BASIS OF AWARD; BALANCED BID. The Agency shall award the Contract to the lowest responsible Bidder submitting a responsive Bid. The lowest Bid will be determined on the basis of the total Bid price. In the event of any discrepancies, written numbers (e.g., fifty, hundred) will govern over numerical numbers (e.g., 50, 100) on the Price Proposal Form. Also, the sum of all lump sum line items will govern over the “Total Proposed Lump Sum Price” line item. The Agency may reject any Bid which, in its opinion when compared to other Bids received or to the Agency’s internal estimates, does not accurately reflect the cost to perform the Work.

Subsurface or latent physical conditions differing materially from those represented in the Contract; 2. Unknown physical conditions of an unusual nature differing materially from those ordinarily encountered and generally recognized as inherent in work of the character being performed; and 3. Material differing from that represented in the Contract which the Contractor believes may be hazardous waste, as defined in Health and Safety Code Section 25117, that is required to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law. The Engineer will promptly investigate conditions which appear to be Changed Conditions. If the Engineer determines that conditions are Changed Conditions and they will materially affect performance time, the Contractor, upon submitting a written request, will be granted an extension of time subject to Section 6-4.2. If the Engineer determines that the conditions do not justify an adjustment in compensation, the Contractor will be notified in writing. This notice will also advise the Contractor of its obligation to notify the Engineer in writing if the Contractor disagrees. The Contractor’s failure to give notice of Changed Conditions promptly upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection with them. 1. The Contractor shall not be entitled to the payment of any additional compensation for any act, or failure to act, by the Engineer, including failure or refusal to issue a Change Order, or for the occurrence of any event or other cause, unless the Contractor shall have first given the Engineer written notice of potential claim as specified in this Section 2-9. Compliance with this section shall not be required as a prerequisite to notice provisions in Section 6-4.2(4) Extensions of Time, nor to any claim that is based on differences in measurement or errors of computation as to Contract quantities. 2. The Contractor shall provide the Agency with a written document containing a description of the particular circumstances giving rise to the potential claim, the reasons for which the Contractor believes additional compensation may be due and the nature of any and all costs involved within 20 Working Days of the date of service of the written notice of potential claim for Changed Conditions. Verbal notifications will not be accepted. 3. The potential claim shall include the following certification relative to the California False Claims Act, Government Code Sections 12650-12656. “The undersigned certifies that the above statements are made in full awareness of the California False Claims Act, Government Code Sections 12650-12656.

The Contractor’s estimate of costs may be updated when actual costs are known. The Contractor shall submit proof of its actual costs to the Engineer within 20 Working Days after the affected Work is completed. Failure to do so shall be cause to deny any later-filed claim regarding a potential claim described in this Section 2-9. 5. The intent of this Section 2-9 is to have differences between the parties arising under the Contract brought to the attention of the Engineer at the earliest possible time so that such matters can be settled, if possible, or other appropriate action promptly taken. 2-10 DISPUTED WORK ADD 2-10.1 Claims. 1. A Claim is a written demand by the Contractor that seeks an adjustment in the Contract Price, Contract Time, or other relief associated with a dispute arising under or relating to the Contract, including a breach of any Contract provision. A voucher, invoice, or other routine request for payment is not a Claim. 2. A Claim shall conform to these specifications and may be considered after the Agency has previously denied a request by the Contractor for a Change Order seeking the demanded relief. 3. The Contractor shall submit a Claim to the Engineer if a dispute occurs that arises from or relates to the Contract. The Claim shall seek all relief to which the Contractor asserts the Contractor is entitled as a result of the event(s) giving rise to the dispute. The Contractor’s failure to process a Claim in accordance with these specifications shall constitute a waiver of all relief associated with the dispute. Claims are subject to 6-10, “Right to Audit.” 4. The Contractor shall continue to perform the Services and Work and shall maintain the Schedule during any dispute proceedings. The Engineer will continue to make payments for undisputed Services and Work. 5. The Agency’s Claims process specified in the Agency Supplement shall not relieve the Contractor of the Contractor’s statutory obligations to present Claims prior to any action under the Government Code. 6. Except for those final payment items disputed in the written statement required in Section 7-3.2, all Claims of any dollar amount shall be submitted in a written statement by the Contractor no later than the date of receipt of the final payment estimate. Those final payment items disputed in the written statement required in Section 7-3.2 shall be submitted no later than 30 Calendar Days after receipt of the Final Payment estimate. No Claim will be considered that was not included in this written statement, nor will any Claim be allowed for which written notice or protest is required under any provision of this Contract, including Sections 2-9 Changed Conditions, 2-10 Disputed Work, 4-1(22) Protection, 6-4.4 Written Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 00 73 00 AGENCY SUPPLEMENTAL GENERAL PROVISIONS Date Printed: September 12, 2025 Document Version: 1.0 Current Update: May 2023 Page 85 of 286 Notice and Report, or 6-4.2(4) Extensions of Time, unless the Contractor has complied with notice or protest requirements. 7. The Engineer will consider Contractor’s filed Claims, which must be detailed enough so the Engineer can determine the basis and amount of the Claims. Contractor shall provide the Engineer additional information to determine the facts or contentions involved in a Claim if requested by the Engineer. If additional information is needed, Contractor must provide Engineer with this information within a reasonable time of being asked for additional information. Failure to submit such information and details will be sufficient cause for denying the Claims. 8. Payment for Claims shall be processed by the next payment application of their resolution for those Claims approved by the Engineer. The Contractor shall proceed with informal dispute resolution under Section 2-10, Disputed Work, for those Claims remaining in dispute. 2-10.1.1 Initiation of Claim. 1. A Claim is a written demand by the Contractor that seeks an adjustment in the Contract Price, Contract Time, or other relief associated with a dispute arising under or relating to the Contract, including a breach of any provision of the Contract. A voucher, invoice, payment application or other routine request for payment is not a Claim. A Claim shall conform to these specifications and may be considered after the City has previously denied a request from the Contractor for a Change Order seeking the demanded relief. The Contractor shall, consistent with 2-10.1.2, give the Agency written notice of Claim prior to commencing any Disputed Work. Failure to give the notice shall constitute a waiver of all Claims in connection with the Disputed Work. If the Contractor and the Agency are unable to reach agreement on Disputed Work, the Agency may direct the Contractor to proceed with the Work and such direction shall not be construed as the Agency directing the Contractor’s mean-and-methods in the execution of the Work. After the Agency has rejected a Change Order request and prior to proceeding with dispute resolution pursuant to the Public Contract Code, applicable provisions of which are specified below, the Contractor shall attempt to resolve all disputes informally through the following dispute resolution chain of command: For claims with a monetary value of $50,000 or less: i. Project Inspector ii. Construction Manager iii. Deputy City Engineer/Engineering Manager For claims with a monetary value greater than $50,000: iv. Project Inspector v. Construction Manager vi. Deputy City Engineer/Engineering Manager vii. City Engineer viii. City Manager or Executive Manager 2. Consistent with Section 2-10.1.2, the Contractor shall submit a complete report within 20 Working Days after completion of the Disputed Work stating its position on the Claim, the contractual basis for the Claim, along with all documentation supporting the costs, Contract Time, and all other evidentiary materials. At each level of Claim or appeal of Claim the Agency will, within 10 Working Days of receipt of the Claim or appeal of Claim, review the Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 00 73 00 AGENCY SUPPLEMENTAL GENERAL PROVISIONS Date Printed: September 12, 2025 Document Version: 1.0 Current Update: May 2023 Page 86 of 286 Contractor’s report and respond with a position, request additional information or request that the Contractor meet and present its report. When additional information or a meeting is requested the Agency will provide its position within 10 Working Days of receipt of the additional information or Contractor’s presentation of its report. The Contractor may appeal each level’s position up to the Deputy City Engineer/Engineering Manager for claims less than $50,000 and/or up to the City Manager for the City of Carlsbad or Executive Manager for the Carlsbad Municipal Water District for claims greater than $50,000 after which the Contractor may proceed under the provisions of the Public Contract Code. The Agency’s failure to state a position or otherwise respond to a Claim within the timeframes set forth above shall be deemed a rejection of the Claim by the Agency. 3. The authority within the dispute resolution chain of command is limited to recommending a resolution to a Claim to the City Manager for the City of Carlsbad or Executive Manager for the Carlsbad Municipal Water District. Actual approval of the Claim is subject to the Change Order provisions in the Contract. 4. Any remaining Claims not resolved by the informal dispute resolution process described above shall be resolved in accordance with Public Contract Code Section 9204, the relevant portion of which is included below: (d)(1)(A) Upon receipt of a Claim pursuant to this section, the public entity to which the Claim applies shall conduct a reasonable review of the Claim and, within a period not to exceed 45 days, shall provide the Claimant a written statement identifying what portion of the Claim is disputed and what portion is undisputed. Upon receipt of a Claim, a public entity and a Contractor may, by mutual agreement, extend the time period provided in this subdivision. (B) The Claimant shall furnish reasonable documentation to support the Claim. (C) If the public entity needs approval from its governing body to provide the Claimant a written statement identifying the disputed portion and the undisputed portion of the Claim, and the governing body does not meet within the 45 days or within the mutually agreed to extension of time following receipt of a Claim sent by registered mail or certified mail, return receipt requested, the public entity shall have up to three days following the next duly publicly noticed meeting of the governing body after the 45-day period, or extension, expires to provide the Claimant a written statement identifying the disputed portion and the undisputed portion. (D) Any payment due on an undisputed portion of the Claim shall be processed and made within 60 days after the public entity issues its written statement. If the public entity fails to issue a written statement, paragraph (3) shall apply. (2)(A) If the Claimant disputes the public entity's written response, or if the public entity fails to respond to a Claim issued pursuant to this section within the time prescribed, the Claimant may demand in writing an informal conference to meet and confer for settlement of the issues in dispute. Upon receipt of a demand in writing sent by registered mail or certified mail, return receipt requested, the public entity Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 00 73 00 AGENCY SUPPLEMENTAL GENERAL PROVISIONS Date Printed: September 12, 2025 Document Version: 1.0 Current Update: May 2023 Page 87 of 286 shall schedule a meet and confer conference within 30 days for settlement of the dispute. (B) Within 10 business days following the conclusion of the meet and confer conference, if the Claim or any portion of the Claim remains in dispute, the public entity shall provide the Claimant a written statement identifying the portion of the Claim that remains in dispute and the portion that is undisputed. Any payment due on an undisputed portion of the Claim shall be processed and made within 60 days after the public entity issues its written statement. Any disputed portion of the Claim, as identified by the Contractor in writing, shall be submitted to nonbinding mediation, with the public entity and the Claimant sharing the associated costs equally. The public entity and Claimant shall mutually agree to a mediator within 10 business days after the disputed portion of the Claim has been identified in writing. If the parties cannot agree upon a mediator, each party shall select a mediator and those mediators shall select a qualified neutral third party to mediate with regard to the disputed portion of the Claim. Each party shall bear the fees and costs charged by its respective mediator in connection with the selection of the neutral mediator. If mediation is unsuccessful, the parts of the Claim remaining in dispute shall be subject to applicable procedures outside this section. (C) For purposes of this section, mediation includes any nonbinding process, including, but not limited to, neutral evaluation or a dispute review board, in which an independent third party or board assists the parties in dispute resolution through negotiation or by issuance of an evaluation. Any mediation utilized shall conform to the timeframes in this section. (D) Unless otherwise agreed to by the public entity and the Contractor in writing, the mediation conducted pursuant to this section shall excuse any further obligation under Section 20104.4 to mediate after litigation has been commenced. (E) This section does not preclude a public entity from requiring arbitration of disputes under private arbitration or the Public Works Contract Arbitration Program if mediation under this section does not resolve the parties' dispute. (3) Failure by the public entity to respond to a Claim from a Contractor within the time periods described in this subdivision or to otherwise meet the time requirements of this section shall result in the Claim being deemed rejected in its entirety. A Claim that is denied by reason of the public entity's failure to have responded to a Claim, or its failure to otherwise meet the time requirements of this section, shall not constitute an adverse finding with regard to the merits of the Claim or the responsibility or qualifications of the Claimant. (4) Amounts not paid in a timely manner as required by this section shall bear interest at 7 percent per annum.

A Subcontractor may request in writing, either on their own behalf or on behalf of a lower tier Subcontractor, that the Contractor present a Claim for work which was performed by the Subcontractor or by a lower tier Subcontractor on behalf of the Subcontractor. The Subcontractor requesting that the Claim be presented to the public entity shall furnish reasonable documentation to support the Claim. Within 45 days of receipt of this written request, the Contractor shall notify the Subcontractor in writing as to whether the Contractor presented the Claim to the public entity and, if the original Contractor did not present the Claim, provide the Subcontractor with a statement of the reasons for not having done so. (e) The text of this section or a summary of it shall be set forth in the Plans or Specifications for any Public Works Project that may give rise to a Claim under this section. (f) A waiver of the rights granted by this section is void and contrary to public policy, provided, however, that (1) upon receipt of a Claim, the parties may mutually agree to waive, in writing, mediation and proceed directly to the commencement of a civil action or binding arbitration, as applicable; and (2) a public entity may prescribe reasonable Change Order, Claim, and dispute resolution procedures and requirements in addition to the provisions of this section, so long as the contractual provisions do not conflict with or otherwise impair the timeframes and procedures set forth in this section.

The Contractor remains responsible for details and accuracy, for coordinating the work with all other associated work and trades, for selecting fabrication processes, for techniques of assembly, and for performing work in a safe manner. B. The review of shop drawings, data, and samples shall NOT be construed: 1. As permitting any departure from requirements of the Standard Specifications ; 2. As relieving the Contractor of responsibility for any errors, including details, dimensions, and materials; 3. As approving departures from details furnished by the District, except as otherwise provided herein. C. If a submittal describes variations and shows a departure from requirements of the Standard Specifications which the District finds to be in the interest of the District and to be so minor as not to involve a change in cost or time for performance, the District may return the reviewed drawings without noting an exception. D. Submittals will be returned to the Contractor under one of the following codes. 1. Code 1 - "NO EXCEPTIONS TAKEN" is assigned when there are no notations or comments to the submittal. When returned under this code the Contractor may release the equipment and/or material for manufacture. 2. Code 2 - "MAKE CORRECTIONS NOTED/CONFIRM" is assigned when notation and comments to the submittal are minor and only a confirmation of the notations and comments is required by the Contractor.

The Contractor may release the equipment or material for manufacture; however, all notations and comments must be incorporated into the final product. 3. Code 3 - "AMEND/RESUBMIT” is assigned when notations and comments are extensive enough to require a resubmittal due to noncompliance with the Standard Specifications. The omissions and nonconforming items must be corrected and the entire package resubmitted. This code generally means that the equipment or material cannot be released for manufacture unless the Contractor takes full responsibility for providing the submitted items in accordance with the Standard Specifications and with all comments and notations incorporated into the final product.

This consent may be withdrawn in whole or in part by SDG&E at any time Consentee fails or refuses to comply with the terms herein, if Consentee constructs improvements other than those described herein as shown on Exhibit “A,” or if Consentee’s Improvements or the method used by Consentee in the construction and installation of said improvements is determined to be in violation of any federal, state, city, county or other governmental entities, laws, ordinances, or regulations, including regulations of the Public Utilities Commission for the State of California. 3 Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 8.

Such removal, restoration, or alteration shall be at the sole cost and expense of Consentee and shall not result in any cost or expense to SDG&E. If Consentee fails to remove, restore, or alter within ninety (90) days after notice, SDG&E shall have the right to remove or alter Consentee’s Improvements and restore the SDG&E Easement area, all at the sole expense and risk of Consentee, which expense Consentee agrees to pay to SDG&E promptly upon demand. 9.

The provision of this paragraph shall not in any way limit any of Consentee’s other obligations or liabilities under this Agreement. If, at any time, a public entity assumes Consentee’s title or interest in or accepts dedication of Consentee’s Improvements, such public entity shall be permitted to self-insure the obligations set forth in this section. 14. Consentee agrees to submit plans for review and approval to SDG&E Land Management prior to commencement of any additional work not expressly permitted hereunder following initial construction and installation of Consentee’s Improvements in the SDG&E Easement area. Such additional work may be approved in SDG&E’s sole discretion and may be subject to approval by the California Public Utilties Commission. 15.

No.: 213-050-16-00 SR: RW#:_ THIS JOINT USE AGREEMENT, dated jAMyAfty 102024 (“Agreement”), by and between SAN DIEGO GAS & ELECTRIC COMPANY, a California corporation (“SDG&E”), and THE CITY OF CARLSBAD, a municipal corporation (“CITY”), is made with reference to the following facts: A. SDG&E is engaged in the business of transmitting and distributing gas and electricity within the City of Carlsbad, County of San Diego, State of California, and holds an easement for gas facilities and appurtenances (“SDG&E Facilities”) located in, upon, over, under, and across that certain easement and right-of- way granted to SDG&E per document recorded on June 27, 1960, as Doc. No. 1960-0129530 of Official Records (“Easement”). B. CITY is now acquiring or has acquired fee title for public street purposes in, upon, over, under, and across the real property described in Exhibit “A” (“City Parcel”), which is attached hereto and by this reference made a part hereof, and intends to construct, operate and maintain therein a publicly dedicated street the location of which is shown on Exhibit “B” attached hereto and made a part hereof. A portion of the proposed dedicated public street will traverse the Easement and shall be referenced to in this agreement as the “Joint Use Area.” C. The dedicated public street referred hereto is shown on the El Camino Real Roadway Improvement Plans No. 6072, Federal No. 5308 (021) FERPL16,a copy of which is on file in the office of the City Engineer of the City of Carlsbad. D. The CITY’S proposed public street dedication serves to widen the existing El Camino Real roadway, which dedication is anticipated to encroach upon the Joint Use Area. E. To accommodate the CITY’S street widening project, SDG&E has been requested by the CITY to consent to the public street dedication within the Joint Use Area. Transfer Tax: None SAN DIEGO GAS & ELECTRIC COMPANY 1 Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC F. CITY and SDG&E desire to provide for the joint use of the Joint Use Area for the construction, operation, and maintenance of the CITY’S public improvements related to the public street dedication consisting of a public street, sidewalk, storm drain and driveway (“CITY Facilities”) and the SDG&E Facilities in, over, under, and across the Joint Use Area. NOW, THEREFORE, for valuable consideration, receipt of which is hereby acknowledged, the parties hereby agree as follows: SDG&E hereby consents that the CITY Facilities may be constructed and maintained over, upon and across the Joint Use Area as shown on said Exhibit “B” subject to the following: (a) In the event that the future use or alteration of the Joint Use Area by the CITY (or a third party involved in a request by the CITY) for streets or public improvements incidental thereto, shall at any time or times necessitate a rearrangement, relocation or reconstruction of any of SDG&E’s Facilities or the acquisition of additional property easements, or both, pursuant thereto, the same shall be performed by SDG&E, or by any other party with the consent of SDG&E, at the cost and expense of the CITY. (b) In the event that the future use of SDG&E’s Easement or the Joint Use Area shall at any time or times necessitate a rearrangement, relocation or reconstruction of the CITY’S Facilities on the Joint Use Area, the same shall be performed at the cost and expense of the CITY. (c) All uses of the Joint Use Area by either party shall be such as will not permanently interrupt the use or operation of the facilities therein of the other party; uses of the Joint Use Area by either party which temporarily interferes with the use of the other party, will be made only when reasonably necessary and will be promptly terminated as soon as the necessity no longer exists. (d) SDG&E retains the right to review and approve the specific locations of all facilities on the Joint Use Area to avoid conflicts with existing and future SDG&E Facilities. Such approvals may be granted by SDG&E’s “Letter of Permission for Grading and Construction of Improvements” and those approvals shall not be unreasonably withheld. (e) If the CITY shall hereafter vacate or abandon, in whole or in part, the Joint Use Area, the CITY shall, in the vacation or abandonment proceedings, reserve to SDG&E all rights owned by SDG&E prior to the execution of this Agreement. (f) Notwithstanding SDG&E’s consent of the City Facilities into the Joint Use Area, the parties agree and acknowledge that this Agreement and not that certain Franchise Agreement between the City and SDG&E effective June 4, 1953, which allows SDG&E to transmit and distribute gas within the City of Carlsbad and for other purposes as may be amended, and any subsequent or successor gas franchise agreement between the parties (“Franchise Agreement”), shall control use of the Joint Use Area. SDG&E is retaining its priority easement interest, which shall not become subject to any Franchise Agreement. 2 Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC (g) Except as expressly herein set forth, this Agreement shall notin any way alter, modify or terminate any of SDG&E’s prior rights in the Joint Use Area.

The City of Carlsbad is proposing to widen a segment of El Camino Real’s (ECR) northbound lanes for approximately 1,400 feet between Cinnabar Way and Camino Vida Roble. In addition to the widening, signing and striping improvements will extend along ECR between Poinsettia Lane and Camino Vida Roble. The Project is located outside of the coastal zone in south- central Carlsbad. See Appendix A for a Vicinity Map. This redevelopment project is subject to the requirements of the San Diego Regional Municipal Separate Storm Sewer System (MS4) Permit (Order No. R9-2013-0001, amended by Order No. R9-2015-0001 and Order No. R9-2013-0100) as well as the City of Carlsbad Engineering Standards. In accordance with City of Carlsbad Storm Water Standards Volume 5 Carlsbad BMP Design Manual (City BMP Manual), the Project qualifies for the Green Streets exemption from Priority Development Project (PDP) requirements. Pursuant to the PDP exemption, the Project is not required to submit a PDP Storm Water Quality Management Plan (SWQMP) or hydromodification management analysis. The drainage analysis associated with the Project can be found in the El Camino Real Improvements Project Final Drainage Report prepared by Dokken Engineering dated February 9, 2021. 2 Water Quality Treatment Requirements The Project proposes to redevelop ECR and must satisfy the federal, regional, and local permanent storm water treatment requirements described in the City BMP Manual. This technical memorandum demonstrates that the storm water requirements are met by utilizing the USEPA Green Streets guidance through incorporation of a biofiltration BMP as well as source control and site design BMPs. The Project is exempt from the additional PDP requirements described in the City BMP Manual and the MS4 Permit. The Project is also subject to the temporary storm water treatment requirements of the Statewide Construction General Permit (Order No. 2009-0009-DWQ), which will be documented in the Storm Water Pollution Prevention Plan prepared by the contractor prior to initiating construction activities. This technical memorandum will focus on the permanent storm water treatment requirements and proposed strategies. 2.1 Federal and State Regulations The federal Clean Water Act (CWA) Section 402 requires point source discharges to be covered by a National Pollutant Elimination System (NPDES) permit. The CWA authorizes and enables states to perform many of the permitting and enforcement aspects of the NPDES program. Depending on the project location, NPDES requirements are implemented by the State Water Resources Control Board (SWRCB), the local Regional Water Quality Control Board, and/or the governing municipality. 2.2 Regional Regulations The regulating body for this project, located in the City of Carlsbad, is the California Regional Water Quality Control Board for San Diego- Region 9, otherwise known as the San Diego Regional Water Quality Control Board (SDRWQCB). The Project involves discharges of municipal storm water and is therefore subject to the SDRWQCB MS4 permit. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Storm Water Technical Memorandum 2 In May 2013, the SDRWQCB issued the MS4 permit (Order No. R9-2013-0001), which identifies storm water requirements for new development and redevelopment projects, to the San Diego area municipal co-permittees. The May 2013 permit was amended in February 2015 by the adoption of Order No. R9-2015-0001. The permit was modified again in November 2015 by Order No. R9-2015-0100. The modified 2015 MS4 permit went into effect February of 2016. Recognizing that structural Best Management Practice (BMP) pollution control implementation standards and techniques will not always be feasible for all new development and redevelopment projects, the SDRWQB included USEPA Green Streets and other exemptions to the PDP project classification that allows for flexibility in how treatment is achieved for each project. See below for an excerpt taken from Provision E.3.b.(3) of the 2013 MS4 permit as applicable to this project: (3) Priority Development Project Exemptions Each Copermittee has the discretion to exempt the following projects from being defined as Priority Development Projects: (a) New or retrofit paved sidewalk, bicycle lanes, or trails that meet the following criteria: (i) Designed and constructed to direct storm water runoff to adjacent vegetated areas, or other non-erodible permeable area; OR (ii) Designed and constructed to be hydraulically disconnected from paved streets or roads; OR (iii) Designed and constructed with permeable pavements or surfaces in accordance with USEPA Green Streets guidance. (b) Retrofitting of redevelopment of existing paved alleys, streets or roads that are designed and constructed in accordance with the USEPA Green Streets guidance. The Project design is consistent with the USEPA Green Street guidance and therefore meets condition (b) for PDP exemption. 2.3 Local Requirements The City of Carlsbad published “City of Carlsbad Engineering Standards: Volume 5 Carlsbad BMP Design Manual” effective February 16, 2016 to provide technical guidance on meeting the City’s storm water management requirements and in compliance with the SDRWQCB 2013 MS4 permit. Contained within the City BMP Manual, the City Storm Water Standard Questionnaire (Form E-35) cites the exemption from PDP requirements for projects constructed in accordance with USEPA Green Streets guidance. The Project will utilize the Green Streets exemption following the BMP Design Fact Sheets located in Appendix E of the City BMP Manual. The County of San Diego Green Street standard plans and design guidance supplement the City guidance. 3 Project Description The Project is located within the City of Carlsbad along ECR, between Poinsettia Lane and Camino Vida Roble. The widening is proposed to complete a missing operational segment of ECR as outlined in the City General Plan. The road is proposed to be widened by a variable distance up to approximately 14 feet from the existing edge of pavement. The proposed northbound lanes will be 11 feet wide with adjacent gutter, curb, and Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Storm Water Technical Memorandum 3 sidewalk. The proposed improvements include a new curb inlet, headwall, storm drain pipe extension, and a stormwater treatment feature. Additional improvements include signing, striping, lighting, and landscaping. 4 Existing Drainage Conditions The Project area is located within the San Marcos Creek and the Encinas Creek watersheds. Generally, runoff originating north of Cinnabar Way is tributary to Encinas Creek and runoff generated south of Cinnabar Way is tributary to San Marcos Creek. Runoff generated from the Project area between Poinsettia Lane and approximately 250 feet south of Cinnabar Way is collected by existing storm drain inlets within the curb and gutter. The inlets connect to underground storm drain systems that ultimately discharge to an unnamed tributary of San Marcos Creek. Flow that bypasses the inlets located 250 feet south of Cinnabar Way drains to Encinas Creek. The only proposed improvements within the San Marcos Creek watershed includes signing and striping. The remainder of the Project is located within the Encinas Creek watershed. Runoff generated between Cinnabar Way and the high point 350 feet south of Camino Vida Roble generally flows to a low point approximately 200 feet north of Cinnabar Way. This portion of ECR is crowned in the center of the roadway, causing runoff to collect along the outside curbs, gutters, and dikes. The northbound lanes, which will be impacted by the Project, drain towards the low point where there is a gap in the dike. Runoff drains through the opening to a natural depression where it is collected by a 24-inch reinforced concrete pipe (RCP) underground storm drain system. This system runs west under ECR to an inlet beyond the southbound lane and continues to the northwest where it eventually discharges to Encinas Creek. From the high point to the intersection of ECR and Camino Vida Roble, ECR is super-elevated to the west toward the raised median, causing runoff to flow to and along the raised median. Runoff generated north of the high point flows to the north, across the ECR southbound lanes, and then west down Camino Vida Roble. This runoff is collected on Camino Vida Roble by the 24-inch RCP underground storm drain system noted above. There are no known existing storm water treatment BMPs within the Project area. 5 Proposed Drainage Conditions The Project proposes to maintain the existing flow patterns. The roadway widening and proposed curb, gutter, and sidewalk requires a new inlet at the low point. The inlet will connect to the existing 24-inch RCP. The grading required for the widening also requires the existing 24-inch RCP to be extended and the existing headwall to be removed and replaced. The proposed Green Streets feature is located between Cinnabar Way and Camino Vida Roble and consists of a 400-foot long biofiltration BMP between ECR’s northbound lanes and the proposed sidewalk. A series of curb cuts are proposed to discharge runoff from ECR to the surface of the biofiltration BMP. An 8-inch perforated underdrain system will collect the treated runoff, which discharges into a proposed cleanout adjacent to the biofiltration BMP. The proposed cleanout discharges to the proposed inlet and existing storm drain system via an 18-inch RCP. Runoff collected along the surface of the biofiltration BMP that exceeds the treatment capacity will discharge back to the roadway via a curb cut at the downstream end of the biofiltration BMP. See Section 6.3 for more details regarding the Green Street BMP selected for the Project. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Storm Water Technical Memorandum 4 6 Storm Water BMPs 6.1 Source Control BMPs Source Control BMPs will be implemented to reduce pollutants that enter the storm drain system from the Project area. Source Control BMPs that will be employed for this project include: • SC-2: Identify the Storm Drain System Using Stenciling or Signage • SC-6: Plazas, Sidewalks, and Parking Lots A storm drain stencil or sign will be provided for the proposed combination inlet. The City of Carlsbad will continue to clean and maintain sidewalks to prevent the accumulation of litter and debris. See Appendix B for the Standard Project Requirement Checklist. 6.2 Site Design BMPs Site Design BMPs will be implemented through the design and construction phases and include practices that preserve natural drainage pathways and reduce the rate and/or volume of storm water runoff. Site design BMPs that will be employed for this project include: • SD-1: Maintain Natural Drainage Pathways and Hydrologic Features • SD-2: Conserve Natural Areas, Soils, and Vegetation • SD-3: Minimize Impervious Area • SD-4: Minimize Soil Compaction • SD-6: Collect Runoff • SD-7: Landscape with Native or Drought Tolerant Species The Project has been designed to maintain natural drainage pathways and hydrologic features by minimizing grading and disturbance of vegetation. The Project minimizes impervious areas to the maximum extent practicable by proposing minimum sidewalk and lane widths. Areas of cut and fill will be minimized to conserve natural areas and vegetation by utilizing 2:1 horizontal to vertical slopes to tie into existing grades at the limits of work. The Project proposes to use landscaping to convey and treat runoff from impervious areas. All landscaped areas will utilize native and/or drought tolerant plants. 6.3 Green Street Elements In accordance with the USEPA Green Street Municipal Handbook, the Project will utilize bioretention with an underdrain to meet the storm water treatment requirements for the project. This BMP type is more specifically referenced as biofiltration by the City BMP Design Manual. Infiltration rate testing was performed at two locations adjacent to the proposed BMP. Results of the testing indicate that infiltration is infeasible. Infiltration test results were consistent with the Natural Resources Conservation Service (NRCS) soil mapping, which indicates low infiltration potential due to the prevalence of Hydrologic Soil Group Type D soils. See Appendix F for the infiltration test results, Infiltration Feasibility Form I-8, and the NRCS Web Soil Survey. The proposed Green Streets feature is located between Cinnabar Way and Camino Vida Roble and consists of a 400-foot long biofiltration BMP between ECR’s northbound lanes and the proposed sidewalk. A series of curb cuts are proposed to discharge runoff from ECR to the surface of the biofiltration BMP. Check dams are proposed to maximize the treated volume along the sloped biofiltration BMP. Storm water will be treated by filtering through layers of the biofiltration BMP including 3 inches of mulch, 18 inches of engineered soil Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Storm Water Technical Memorandum 5 media, 3 inches of sand and gravel (choker or filter course layer), and 12 inches of gravel. Due to the poor infiltration conditions of the underlying soils, the sides and bottom of the biofiltration BMP will be lined with a 30-millimeter plastic liner. An 8-inch perforated underdrain system with overflow risers and cleanouts will span the length of the biofiltration BMP to collect the treated runoff, which discharges to the downstream storm drain system. The biofiltration BMP will treat existing, replaced, and new impervious surfaces along the ECR northbound lanes south of the high point near Camino Vida Roble. Due to the topography, existing storm drain facilities, and low infiltration rates, it is infeasible to treat runoff originating north of this high point. See Appendix E for an exhibit that shows the location of the biofiltration BMP and the treated impervious areas. The sum of the impervious areas treated by the biofiltration BMP exceeds the total new and replaced impervious surface area for the Project. Although the Project is not subject to PDP requirements, the treated area is consistent with such requirements. Table 1 summarizes the approximate water quality areas. Table 1: Treatment Area Summary Table Proposed New/Replaced Impervious Area Treated Impervious Area (square feet) (square feet) 46,400 48,000 To demonstrate that the Project meets equivalent PDP requirements using Green Street methods, a design capture volume (DCV) for the project was determined, which was used to size the proposed biofiltration BMP. The Green Street project equivalent DCV for the project is 3,148 cubic feet. See Appendix C and Appendix D for the DCV and BMP sizing calculations, respectively. No credits for site design could be applied and, due to poor infiltration conditions, only 315 cubic feet of stormwater is considered to be reliably retained by the biofiltration BMP pore spaces based on the Simple Sizing Method for Biofiltration BMPs included in Appendix D. In order to meet the equivalent PDP requirements, the BMP must either treat 1.5 times the remaining DCV (Option 1) or biofilter as flow-thru design with a BMP volume including pore space and ponding sized at 75% of the remaining DCV (Option 2). Additionally, the biofiltration BMP minimum treatment surface area requirement is 3% of the contributing area times the adjusted runoff factor or coefficient. The design calculations show that the proposed biofiltration BMP sizing satisfies both Option 1 and 2 as well as the minimum 3% surface area requirement. Based on the proposed surface ponding and media thicknesses, the minimum biofiltration footprint is 1,778 square feet compared to the proposed 1,800 square foot biofiltration BMP treatment surface area. 7 Operations and Maintenance The property owner for the Project is the City of Carlsbad. The proposed BMP requires regular maintenance to operate effectively and as designed in order to meet the requirements of the MS4 permit. Maintenance is needed at more frequent intervals shortly after construction to establish vegetation, which reduces to quarterly, then annually or as needed. The BMP is accessible by vehicle and on foot via ECR. There is no street parking adjacent to the BMP, however, the adjacent bike lane and shoulder could accommodate maintenance vehicles with minor traffic control. An existing sewer easement near the south end of the BMP is also a viable access point. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Storm Water Technical Memorandum 6 Equipment required for BMP maintenance is standard for public works. Weeding and waste removal are the most common maintenance tasks associated with the BMP. Trash, debris, and weeds are most easily removed by hand, as necessary. If smaller rain events result in standing water for more than a day, cleanout flushing of the underdrain system will restore functionality in most cases. Local BMP guidance suggests that with proper maintenance, replacement of soil and/or gravel media layers will be required approximately once every ten years. See Appendix G for an operations and maintenance schedule. 8 Conclusion The El Camino Real Improvements Project proposes widening and adding sidewalk to the northbound lane of ECR between Cinnabar Lane and Camino Vida Roble as well as signing and striping improvements to the northbound lanes of ECR between Poinsettia Lane and Camino Vida Roble. One 400-foot long biofiltration BMP was proposed and sized to the maximum extent practical (MEP) in accordance with the USEPA Green Street guidance. The proposed biofiltration BMP treats approximately 48,000 square feet of impervious area, which exceeds the total new and replaced impervious area generated by the Project. The proposed 1,800 square foot biofiltration BMP treatment surface area exceeds the minimum biofiltration footprint of 1,778 square feet. The Project qualifies for the Green Streets PDP exemption and complies with regional MS4 permit. This storm water technical memorandum demonstrates that the Project is compliant with all applicable federal, state, regional, and local storm water treatment requirements. 9 References City of Carlsbad, February 2016.

This questionnaire must be completed by the applicant in advance of submitting for a development application (subdivision, discretionary permits and/or construction permits). The results of the questionnaire determine the level of storm water standards that must be applied to a proposed development or redevelopment project. Depending on the outcome, your project will either be subject to ‘STANDARD PROJECT’requirements or be subject to ‘PRIORITY DEVELOPMENT PROJECT’ (PDP) requirements. Your responses to the questionnaire represent an initial assessment of the proposed project conditions and impacts. City staff has responsibility for making the final assessment after submission of the development application. If staff determines that the questionnaire was incorrectly filled out and is subject to more stringent storm water standards than initially assessed by you, this will result in the return of the development application as incomplete. In this case, please make the changes to the questionnaire and resubmit to the city. If you are unsure about the meaning of a question or need help in determining how to respond to one or more of the questions, please seek assistance from Land Development Engineering staff. A completed and signed questionnaire must be submitted with each development project application.

STEP 5CHECK THE APPROPRIATE BOX AND COMPLETE APPLICANT INFORMATION My project is a PDP and must comply with PDP stormwater requirements of the BMP Manual. I understand I must prepare a Storm Water Quality Management Plan (SWQMP)for submittal at time of application. My project is a ‘STANDARD PROJECT’ OR EXEMPT from PDP and must only comply with ‘STANDARD PROJECT’ stormwater requirements of the BMP Manual. As part of these requirements, I will submit a “Standard Project Requirement Checklist Form E-36” and incorporate low impact development strategies throughout my project. Note: For projects that are close to meeting the PDP threshold, staff may require detailed impervious area calculations and exhibits to verify if ‘STANDARD PROJECT’ stormwater requirements apply. My Project is NOT a ‘development project’ and is not subject to the requirements of the BMP Manual.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

DISADVANTAGED BUSINESS ENTERPRISES (DBE) The contractor, subrecipient or subcontractor shall take necessary and reasonable steps to ensure that DBEs have opportunity to participate in the contract (49 CFR 26). To ensure equal participation of DBEs provided in 49 CFR 26.5, the Agency shows a contract goal for DBEs. The prime contractor shall make work available to DBEs and select work parts consistent with available DBE subcontractors and suppliers. The prime contractor shall meet the DBE goal shown elsewhere in these special provisions or demonstrate that they made adequate Good Faith Efforts (GFE) to meet this goal. An adequate GFE means that the bidder must show that it took all necessary and reasonable steps to achieve a DBE goal that, by their scope, intensity, and appropriateness to the objective, could reasonably be expected to meet the DBE goal. If the DBE goal is not met, the contractor needs to complete and submit the DBE GFE documentation as described in Local Assistance Procedures Manual (LAPM) Chapter 9, Section 9.8 within 5 (five) days of bid opening. It is the prime contractor’s responsibility to verify that the DBE firm is certified as a DBE on the date of bid opening by using the California Unified Certification Program (CUCP) database and possesses the most specific available North American Industry Classification System (NAICS) codes and Work Code applicable to the type of work the firm will perform on the contract. Additionally, the prime contractor is responsible to document this verification by printing out the CUCP data for each DBE firm. A list of DBEs certified by the CUCP can be found at: https://dot.ca.gov/programs/civil-rights/dbe-search. DBE participation will only count toward the California Department of Transportation’s federally mandated statewide overall DBE goal if the DBE performs a commercially useful function under 49 CFR 26.55. Credit for materials or supplies the prime contractor purchases from DBEs counts towards the goal in the following manner: • 100 percent counts if the materials or supplies are obtained from a DBE manufacturer. • 60 percent counts if the materials or supplies are obtained from a DBE regular dealer. • Only fees, commissions, and charges for assistance in the procurement and delivery of materials or supplies count if obtained from a DBE that is neither a manufacturer nor regular dealer. 49 CFR 26.55 defines "manufacturer" and "regular dealer." The prime contractor receives credit towards the goal if they employ a DBE trucking company that performs a commercially useful function as defined in 49 CFR 26.55(d) as follows: • The DBE must be responsible for the management and supervision of the entire trucking operation for which it is responsible on a particular contract, and there cannot be a contrived arrangement for the purpose of meeting DBE goals. • The DBE must itself own and operate at least one fully licensed, insured, and operational truck used on the contract. • The DBE receives credit for the total value of the transportation services it provides on the Contract using trucks it owns, insures, and operates using drivers it employs. • The DBE may lease trucks from another DBE firm, including an owner-operator who is certified as a DBE. The DBE who leases trucks from another DBE receives credit for the total value of the transportation services the lessee DBE provides on the Contract. • The DBE may also lease trucks from a non-DBE firm, including from an owner-operator. The DBE that leases trucks equipped with drivers from a non-DBE is entitled to credit for the total value of transportation services provided by non-DBE leased trucks equipped with drivers not to exceed the value of transportation services on the contract provided by DBE-owned trucks or leased trucks with DBE employee drivers. Additional participation by non-DBE owned trucks equipped with drivers receives credit only for the fee or commission it receives as a result of the lease arrangement. • The DBE may lease trucks without drivers from a non-DBE truck leasing company. If the DBE leases trucks from a non-DBE truck leasing company and uses its own employees as drivers, it is entitled to credit for the total value of these hauling services. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 3 of 21 October 2023 • A lease must indicate that the DBE has exclusive use of and control over the truck. This does not preclude the leased truck from working for others during the term of the lease with the consent of the DBE, so long as the lease gives the DBE absolute priority for use of the leased truck. Leased trucks must display the name and identification number of the DBE. A. Nondiscrimination Statement The contractor, subrecipient or subcontractor will never exclude any person from participation in, deny any person the benefits of, or otherwise discriminate against anyone in connection with the award and performance of any contract covered by 49 CFR 26 on the basis of race, color, sex, or national origin. In administering the Local Agency components of the DBE Program Plan, the contractor, subrecipient or subcontractor will not, directly, or through contractual or other arrangements, use criteria or methods of administration that have the effect of defeating or substantially impairing accomplishment of the objectives of the DBE Program Plan with respect to individuals of a particular race, color, sex, or national origin. B. Contract Assurance Under 49 CFR 26.13(b): The contractor, subrecipient or subcontractor shall not discriminate on the basis of race, color, national origin, or sex in the performance of this contract. The contractor shall carry out applicable requirements of 49 CFR 26 in the award and administration of federal-aid contracts. Failure by the contractor to carry out these requirements is a material breach of this contract, which may result in the termination of this contract or such other remedy as the recipient deems appropriate, which may include, but is not limited to: (1) Withholding monthly progress payments; (2) Assessing sanctions; (3) Liquidated damages; and/or (4) Disqualifying the contractor from future bidding as non-responsible. C. Prompt Progress Payment In accordance with California Business and Professions Code section 7108.5, the prime contractor or subcontractor shall pay to any subcontractor, not later than seven days after receipt of each progress payment, unless otherwise agreed to in writing, the respective amounts allowed the contractor on account of the work performed by the subcontractors, to the extent of each subcontractor’s interest therein. In the event that there is a good faith dispute over all or any portion of the amount due on a progress payment from the prime contractor or subcontractor to a subcontractor, the prime contractor or subcontractor may withhold no more than 150 percent of the disputed amount. Any violation of this requirement shall constitute a cause for disciplinary action and shall subject the licensee to a penalty, payable to the subcontractor, of 2 percent of the amount due per month for every month that payment is not made. In any action for the collection of funds wrongfully withheld, the prevailing party shall be entitled to his or her attorney’s fees and costs. The sanctions authorized under this requirement shall be separate from, and in addition to, all other remedies, either civil, administrative, or criminal. This clause applies to both DBE and non-DBE subcontractors. D. Prompt Payment of Withheld Funds to Subcontractors The Agency may hold retainage from the prime contractor and shall make prompt and regular incremental acceptances of portions, as determined by the Agency, of the contract work, and pay retainage to the prime contractor based on these acceptances. The Agency shall designate one of the methods below in the contract to ensure prompt and full payment of any retainage kept by the prime contractor or subcontractor to a subcontractor. The Agency shall include either Method 1, Method 2, or Method 3 below and delete the other two. Method 1: No retainage will be held by the Agency from progress payments due to the prime contractor. Prime contractors and subcontractors are prohibited from holding retainage from subcontractors. Any delay or postponement of payment may take place only for good cause and with the Agency’s prior written approval. Any violation of these provisions shall subject the violating contractor or subcontractor to the penalties, sanctions, and other remedies specified in Section 7108.5 of the California Business and Professions Code and Section 10262 of the California Public Contract Code. This requirement shall not be construed to limit or impair any contractual, administrative or judicial remedies, otherwise available to the Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 4 of 21 October 2023 contractor or subcontractor in the event of a dispute involving late payment or nonpayment by the contractor, deficient subcontractor performance and/or noncompliance by a subcontractor. This clause applies to both DBE and non-DBE subcontractors. Method 2: No retainage will be held by the Agency from progress payments due to the prime contractor. Any retainage kept by the prime contractor or by a subcontractor must be paid in full to the earning subcontractor within seven (7) days after the subcontractor’s work is satisfactorily completed. Any delay or postponement of payment may take place only for good cause and with the Agency’s prior written approval. Any violation of these provisions shall subject the violating contractor or subcontractor to the penalties, sanctions, and remedies specified in Section 7108.5 of the California Business and Professions Code and Section 10262 of the California Public Contract Code. This requirement shall not be construed to limit or impair any contractual, administrative or judicial remedies, otherwise available to the contractor or subcontractor in the event of a dispute involving late payment or nonpayment by the contractor, deficient subcontractor performance and/or noncompliance by a subcontractor. This clause applies to both DBE and non-DBE subcontractors. Method 3: The Agency shall hold retainage from the prime contractor and shall make prompt and regular incremental acceptances of portions, as determined by the Agency of the contract work and pay retainage to the prime contractor based on these acceptances. The prime contractor or subcontractor shall return all monies withheld in retention from all subcontractors within seven (7) days after receiving payment for work satisfactorily completed and accepted including incremental acceptances of portions of the contract work by the Agency. Any delay or postponement of payment may take place only for good cause and with the Agency’s prior written approval. Any violation of these provisions shall subject the violating prime contractor or subcontractor to the penalties, sanctions, and other remedies specified in Section 7108.5 of the California Business and Professions Code and Section 10262 of the California Public Contract Code. This requirement shall not be construed to limit or impair any contractual, administrative or judicial remedies otherwise available to the contractor or subcontractor in the event of a dispute involving late payment or nonpayment by the contractor; deficient subcontractor performance and/or noncompliance by a subcontractor. This clause applies to both DBE and non-DBE subcontractors. Any violation of these provisions of Prompt Progress Payment and Prompt Payment of Withheld Funds to Subcontractors shall subject the violating prime contractor or subcontractor to the penalties, sanctions and other remedies specified therein. These requirements shall not be construed to limit or impair any contractual, administrative, or judicial remedies otherwise available to the prime contractor or subcontractor in the event of a dispute involving late payment or nonpayment by the prime contractor, deficient subcontract performance, or noncompliance by a subcontractor. E. Termination and Replacement of DBE Subcontractors The prime contractor shall utilize the specific DBEs listed to perform the work and supply the materials for which each is listed unless the contractor obtains the Agency’s written consent. The prime contractor shall not terminate or replace a listed DBE for convenience and perform the work with their own forces or obtain materials from other sources without prior written authorization from the Agency. Unless the Agency’s prior written consent is provided, the contractor shall not be entitled to any payment for work or material unless it is performed or supplied by the listed DBE on the Exhibit 15-G Construction Contract DBE Commitment form, included in the Bid. Termination of DBE Subcontractors After a contract with a specified DBE goal has been executed, termination of a DBE may be allowed for the following, but not limited to, justifiable reasons with prior written authorization from the Agency: 1. Listed DBE fails or refuses to execute a written contract based on plans and specifications for the project. 2. The Local Agency stipulated that a bond is a condition of executing the subcontract and the listed DBE fails to meet the Local Agency’s bond requirements. 3. Work requires a contractor's license and listed DBE does not have a valid license under Contractors License Law, or is not properly registered with the California Department of Industrial Relations as a public works contractor. 4. Listed DBE fails or refuses to perform the work or furnish the listed materials (failing or refusing to Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 5 of 21 October 2023 perform is not an allowable reason to remove a DBE if the failure or refusal is a result of bad faith or discrimination). 5. Listed DBE's work is unsatisfactory and not in compliance with the contract. 6. Listed DBE is ineligible to work on the project because of suspension or debarment. 7. Listed DBE becomes bankrupt or insolvent or exhibits credit unworthiness. 8. Listed DBE voluntarily withdraws with written notice from the Contract 9. Listed DBE is ineligible to receive credit for the type of work required. 10. Listed DBE owner dies or becomes disabled resulting in the inability to perform the work on the Contract. 11. The Agency determines other documented good cause. To terminate a DBE or to terminate a portion of a DBE's work, the contractor must use the following procedures: 1. Send a written notice to the DBE of Contractor’s intent to use other forces or material sources and include one or more justifiable reasons listed above. Simultaneously send a copy of this written notice to the Agency. The written notice to the DBE must request they provide any response within five (5) business days to both the Contractor and the Agency by either acknowledging their agreement or documenting their reasoning as to why the use of other forces or sources of materials should not occur. 2. If the DBE does not respond within 5 business days, Contractor may move forward with the request as if the DBE had agreed to Contractor’s written notice. 3. Submit Contractor’s DBE termination request by written letter to the Agency and include: • One or more above listed justifiable reasons along with supporting documentation. • Contractor’s written notice to the DBE regarding the request, including proof of transmission and tracking documentation of Contractor’s written notice • The DBE's response to Contractor’s written notice, if received. If a written response was not provided, provide a statement to that effect. The Agency shall respond in writing to Contractor’s DBE termination request within 5 business days. Replacement of DBE Subcontractors After receiving the Agency’s written authorization of DBE termination request, the Contractor must obtain the Agency’s written agreement for DBE replacement. The Contractor must find or demonstrate GFEs to find qualified DBE replacement firms to perform the work to the extent needed to meet the DBE commitment. The following procedures shall be followed to request authorization to replace a DBE firm: 1. Submit a request to replace a DBE with other forces or material sources in writing to the Agency which must include: a. Description of remaining uncommitted work items made available for replacement DBE solicitation and participation. b. The proposed DBE replacement firm's business information, the work they have agreed to perform, and the following: • Quote for bid item work and description of work to be performed • Proposed subcontract agreement and written confirmation of agreement to perform on the Contract • Revised Subcontracting Request form • Revised Exhibit 15-G: Construction Contract DBE Commitment 2. If Contractor has not identified a DBE replacement firm, submit documentation of the Contractor’s GFEs Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 6 of 21 October 2023 to use DBE replacement firms within 7 days of Agency's authorization to terminate the DBE. The Contractor may request the Agency's approval to extend this submittal period to a total of 14 days. Submit documentation of actions taken to find a DBE replacement firm, such as: • Search results of certified DBEs available to perform the original DBE work identified and/or other work the Contractor had intended to self-perform, to the extent needed to meet the DBE commitment • Solicitations of DBEs for performance of work identified • Correspondence with interested DBEs that may have included contract details and requirements • Negotiation efforts with DBEs that reflect why an agreement was not reached • If a DBE's quote was rejected, provide Contractor’s reasoning for the rejection, such as why the DBE was unqualified for the work, or why the price quote was unreasonable or excessive • Copies of each DBE's and non-DBE's price quotes for work identified, as the Agency may contact the firms to verify solicitation efforts and determine if the DBE quotes are substantially higher • Additional documentation that supports the GFE The Agency shall respond in writing to the Contractor’s DBE replacement request within five (5) business days. The Contractor must submit a revised Subcontracting Request form if the replacement plan is authorized by the Agency. F. Commitment and Utilization The Agency’s DBE program must include a monitoring and enforcement mechanism to ensure that DBE commitments reconcile to DBE utilization. The bidder shall complete and sign Exhibit 15-G: Construction Contract DBE Commitment included in the contract documents regardless of whether DBE participation is reported. The bidder shall provide written confirmation from each DBE that the DBE is participating in the Contract. LAPM Exhibit 9-I: DBE Confirmation or equivalent form and DBE’s quote must be submitted. The written confirmation must be submitted no later than 4pm on the 5th day after bid opening. If a DBE is participating as a joint venture partner, the bidder shall submit a copy of the joint venture agreement. If the DBE Commitment form, Exhibit 15-G, is not submitted with the bid, it must be completed and submitted by all bidders to the Agency within five (5) days of bid opening. If the bidder does not submit the DBE Commitment form within the specified time, the Agency will find the bidder’s bid nonresponsive. The prime contractor shall use each DBE subcontractor as listed on Exhibit 15-G: Construction Contract DBE Commitment unless they receive written authorization for a termination or replacement from the Agency. The Agency shall request the prime contractor to: 1. Notify the Resident Engineer or Inspector of any changes to its anticipated DBE participation 2. Provide this notification before starting the affected work 3. Maintain records including: • Name and business address of each 1st-tier subcontractor • Name and business address of each DBE subcontractor, DBE vendor, and DBE trucking company, regardless of tier • Date of payment and total amount paid to each DBE (see Exhibit 9-F: Monthly Disadvantaged Business Enterprise Payment) If the prime contractor is a DBE contractor, they shall include the date of work performed by their own forces and the corresponding value of the work. Before the 15th of each month, the prime contractor shall submit a Monthly DBE Trucking Verification (LAPM Exhibit 16-Z1) form. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 7 of 21 October 2023 If a DBE is decertified before completing its work, the DBE must notify the prime contractor in writing of the decertification date. If a business becomes a certified DBE before completing its work, the business must notify the prime contractor in writing of the certification date. The prime contractor shall submit the notifications. Upon work completion, the prime contractor shall complete a Disadvantaged Business Enterprises (DBE) Certification Status Change, Exhibit 17-O, form and submit the form within 30 days of contract acceptance. Upon work completion, the prime contractor shall complete Exhibit 17-F: Final Report – Utilization of Disadvantaged Business Enterprises (DBE), First-Tier Subcontractors and submit it within 90 days of contract acceptance. The Agency will withhold $10,000 until the form is submitted. The Agency releases the withhold upon submission of the completed form. G. Running Tally of Attainments For projects awarded on or after March 1, 2020, but before September 1, 2023: After submitting an invoice for reimbursement that includes a payment to a DBE, but no later than the 10th of the following month, the prime contractor/consultant must complete and email the Exhibit 9-F: Disadvantaged Business Enterprise Running Tally of Payments to business.support.unit@dot.ca.gov with a copy to local administering agencies. For projects that are awarded on or after September 1, 2023: Exhibit 9-F is no longer required. Instead, by the 15th of the month following the month of any payment(s), the prime contractor must now submit Exhibit 9-P to the Local Agency administering the contract. If the Contractor does not make any payments to subcontractors, supplier(s) and/or manufacturers they must report “no payments were made to subs this month” and write this visibly and legibly on Exhibit 9-P. H. Commercially Useful Function DBEs must perform a commercially useful function (CUF) under 49 CFR 26.55 when performing work or supplying materials listed on the DBE Commitment form. The DBE value of work will only count toward the DBE commitment if the DBE performs a CUF. A DBE performs a CUF when it is responsible for execution of the work on the contract and is carrying out its responsibilities by actually performing, managing, and supervising the work involved. If a DBE does not perform or exercise responsibility for at least 30% of the total cost of its contract with its own work force, or the DBE subcontracts a greater portion of the work of a contract than would be expected on the basis of normal industry practice for the type of work involved, it will be presumed that the DBE is not performing a CUF. Additionally, the DBE must also be responsible, with respect to materials and supplies used on the contract, for negotiating price, determining quality and quantity, ordering the material and installing (where applicable), and paying for the material itself. The Contractor must perform CUF evaluation for each DBE company working on a federal-aid contract, with or without a DBE goal. Perform a CUF evaluation at the beginning of the DBE’s work, and continue to monitor the performance of CUF for the duration of the project. The Contractor must provide written notification to the AGENCY at least 15 days in advance of each DBE's initial performance of work or supplying materials for the Contract. The notification must include the DBE's name, work the DBE will perform on the contract, and the location, date, and time of where their work will take place. Within 10 (ten) days of a DBE initially performing work or supplying materials on the contract, the Contractor shall submit to the LPA the initial evaluation and validation of DBE performance of a CUF using the LAPM 9-J: Disadvantaged Business Enterprise Commercially Useful Function Evaluation. Include the following information with the submittal: • Subcontract agreement with the DBE • Purchase orders • Bills of lading • Invoices • Proof of payment Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 8 of 21 October 2023 The Contractor must monitor all DBE’s performance of CUF by conducting quarterly evaluations and validations throughout their duration of work on the contract using the LAPM 9-J: DBE Commercially Useful Function Evaluation. The Contractor must submit to the AGENCY these quarterly evaluations and validations by the 5th of the month for the previous three (3) months of work. The Contractor must notify the AGENCY immediately if the Contractor believes the DBE may not be performing a CUF. The AGENCY will verify DBEs performance of CUF by reviewing the initial and quarterly submissions of LAPM 9-J: DBE Commercially Useful Function Evaluation, submitted supporting information, field observations, and through any additional AGENCY evaluations. The AGENCY must evaluate DBEs and their CUF performance throughout the duration of a Contract. The AGENCY will provide written notice to Contractor and DBE at least two (2) business days prior to any evaluation. The Contractor and DBE must participate in the evaluation. Upon completing the evaluation, the AGENCY must share the evaluation results with the Contractor and DBE. An evaluation could include items that must be remedied upon receipt. If the AGENCY determines the DBE is not performing a CUF the Contractor must suspend performance of the noncompliant work. The Contractor and DBEs must submit any additional CUF related records and documents within five (5) business days of AGENCY’s request such as: • Proof of ownership or lease and rental agreements for equipment • Tax records • Employee rosters • Certified payroll records • Inventory rosters Failure to submit required DBE Commercially Useful Function Evaluation forms or requested records and documents can result in withholding of payment for the value of work completed by the DBE. If the Contractor and/or the AGENCY determine that a listed DBE is not performing a CUF in performance of their DBE committed work, immediately suspend performance of the noncompliant portion of the work. The AGENCY may deny payment for the noncompliant portion of the work. The AGENCY will ask the Contractor to submit a corrective action plan (CAP) to the AGENCY within five (5) days of the noncompliant CUF determination. The CAP must identify how the Contractor will correct the noncompliance findings for the remaining portion of the DBE's work. The AGENCY has five (5) days to review the CAP in conjunction with the prime contractor’s review. The Contractor must implement the CAP within five (5) days of the AGENCY's approval. The AGENCY will then authorize the prior noncompliant portion of work for the DBE's committed work. If corrective actions cannot be accomplished to ensure the DBE performs a CUF on the Contract, then the Contractor may have good cause to request termination of the DBE. I. Use of Joint Checks A joint check may be used between the Contractor or lower-tier subcontractor and a DBE subcontractor purchasing materials from a material supplier if the contractor obtains prior approval from the LPA for the proposed use of joint check upon submittal of the LAPM 9-K: DLA Disadvantaged Business Enterprises (DBE) Joint Check Agreement Request form. To use a joint check, the following conditions must be met: • All parties, including the Contractor, must agree to the use of a joint check • Entity issuing the joint check acts solely to guarantee payment • DBE must release the check to the material supplier • LPA must authorize the request before implementation • Any party to the agreement must provide requested documentation within 10 days of the LPA's request for the documentation • Agreement to use a joint check must be short-term, not to exceed 1 year, allowing sufficient time needed to establish or increase a credit line with the material supplier Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 9 of 21 October 2023 A request for a joint check agreement may be initiated by any party. If a joint check is used, the DBE remains responsible for all elements of 49 CFR 26.55(c)(1). Failure to comply with the above requirements disqualifies DBE participation and results in no credit and no payment to the Contractor for DBE participation. A joint check may not be used between the Contractor or subcontractor and a DBE regular dealer, bulk material supplier, manufacturer, wholesaler, broker, trucker, packager, manufacturer’s representative, or other persons who arrange or expedite transactions. 2. BID OPENING The Agency publicly opens and reads bids at the time and place shown on the Notice to Contractors. 3. BID RIGGING The U.S. Department of Transportation (DOT) provides a toll-free hotline to report bid rigging activities. Use the hotline to report bid rigging, bidder collusion, and other fraudulent activities. The hotline number is (800) 424- 9071. The service is available 24 hours 7 days a week and is confidential and anonymous. The hotline is part of the DOT's effort to identify and investigate highway construction contract fraud and abuse and is operated under the direction of the DOT Inspector General. 4. CONTRACT AWARD If the Agency awards the contract, the award is made to the lowest responsible and responsive bidder. 5. CONTRACTOR LICENSE The Contractor must be properly licensed as a contractor from contract award through Contract acceptance (23 CFR 635.110). 6. CHANGED CONDITIONS A. Differing Site Conditions 1. During the progress of the work, if subsurface or latent physical conditions are encountered at the site differing materially from those indicated in the contract or if unknown physical conditions of an unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in the work provided for in the contract, are encountered at the site, the party discovering such conditions shall promptly notify the other party in writing of the specific differing conditions before the site is disturbed and before the affected work is performed. 2. Upon written notification, the engineer will investigate the conditions, and if it is determined that the conditions materially differ and cause an increase or decrease in the cost or time required for the performance of any work under the contract, an adjustment, excluding anticipated profits, will be made and the contract modified in writing accordingly. The engineer will notify the contractor of the determination whether or not an adjustment of the contract is warranted. 3. No contract adjustment which results in a benefit to the contractor will be allowed unless the contractor has provided the required written notice. 4. No contract adjustment will be allowed under this clause for any effects caused on unchanged work. [This provision may be omitted by the Local Agency, at their option.] B. Suspensions of Work Ordered by the Engineer 1. If the performance of all or any portion of the work is suspended or delayed by the engineer in writing for an unreasonable period of time (not originally anticipated, customary, or inherent to the construction industry) and the contractor believes that additional compensation and/or contract time is due as a result of such suspension or delay, the contractor shall submit to the engineer in writing a request for adjustment within 7 calendar days of receipt of the notice to resume work. The request shall set forth the reasons and support for such adjustment. 2. Upon receipt, the engineer will evaluate the contractor's request. If the engineer agrees that the cost and/or time required for the performance of the contract has increased as a result of such suspension and the suspension was caused by conditions beyond the control of and not the fault of the contractor, its suppliers, or subcontractors at any approved tier, and not caused by weather, the engineer will make an adjustment (excluding profit) and modify the contract in writing accordingly. The contractor will be notified of the engineer's determination whether or not an adjustment of the contract is warranted. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 10 of 21 October 2023 3. No contract adjustment will be allowed unless the contractor has submitted the request for adjustment within the time prescribed. 4. No contract adjustment will be allowed under this clause to the extent that performance would have been suspended or delayed by any other cause, or for which an adjustment is provided or excluded under any other term or condition of this contract. C. Significant Changes in the Character of Work 1. The engineer reserves the right to make, in writing, at any time during the work, such changes in quantities and such alterations in the work as are necessary to satisfactorily complete the project. Such changes in quantities and alterations shall not invalidate the contract nor release the surety, and the contractor agrees to perform the work as altered. 2. If the alterations or changes in quantities significantly change the character of the work under the contract, whether such alterations or changes are in themselves significant changes to the character of the work or by affecting other work cause such other work to become significantly different in character, an adjustment, excluding anticipated profit, will be made to the contract. The basis for the adjustment shall be agreed upon prior to the performance of the work. If a basis cannot be agreed upon, then an adjustment will be made either for or against the contractor in such amount as the engineer may determine to be fair and equitable. 3. If the alterations or changes in quantities do not significantly change the character of the work to be performed under the contract, the altered work will be paid for as provided elsewhere in the contract. 4. The term “significant change” shall be construed to apply only to the following circumstances: • When the character of the work as altered differs materially in kind or nature from that involved or included in the original proposed construction; or • When a major item of work, as defined elsewhere in the contract, is increased in excess of 125 percent or decreased below 75 percent of the original contract quantity. Any allowance for an increase in quantity shall apply only to that portion in excess of 125 percent of original contract item quantity, or in case of a decrease below 75 percent, to the actual amount of work performed. 7. BEGINNING OF WORK, TIME OF COMPLETION AND LIQUIDATED DAMAGES The Contractor shall begin work within 15 calendar days after the issuance of the Notice to Proceed. This work shall be diligently prosecuted to completion before the expiration of WORKING DAYS beginning on the fifteenth calendar day after the date shown on the Notice to Proceed. The Contractor shall pay to the City/County the sum of $ per day, for each and every calendar days’ delay in finishing the work in excess of the number of working days prescribed above. 8. BUY AMERICA Buy America Requirements apply to steel and iron, manufactured products, and construction materials permanently incorporated into the project. Steel and Iron Materials All steel and iron materials must be melted and manufactured in the United States except: 1. Foreign pig iron and processed, pelletized, and reduced iron ore may be used in the domestic production of the steel and iron materials [60 Fed Reg 15478 (03/24/1995)]; 2. If the total combined cost of the materials produced outside the United States does not exceed the greater of 0.1 percent of the total contract amount or $2,500, materials produced outside the United States may be used if authorized. Furnish steel and iron materials to be incorporated into the work with certificates of compliance and certified mill test reports. Mill test reports must indicate where the steel and iron were melted and manufactured.

TITLE VI ASSURANCES [The U.S. Department of Transportation Order No.1050.2A requires all federal-aid Department of Transportation contracts between an agency and a contractor to contain Appendix A and E. Note: Appendix B only requires inclusion if the contract impacts deeds effecting or recording the transfer of real property, structures, or improvements thereon, or granting interest therein. Appendices C and D only require inclusion if the contract impacts deeds, licenses, leases, permits, or similar instruments entered into by the recipient.] APPENDIX A During the performance of this Agreement, the contractor, for itself, its assignees and successors in interest (hereinafter collectively referred to as CONTRACTOR) agrees as follows: a. Compliance with Regulations: CONTRACTOR shall comply with the regulations relative to nondiscrimination in federally assisted programs of the Department of Transportation, Title 49, Code of Federal Regulations, Part 21, as they may be amended from time to time, (hereinafter referred to as the REGULATIONS), which are herein incorporated by reference and made a part of this agreement. b. Nondiscrimination: CONTRACTOR, with regard to the work performed by it during the AGREEMENT, shall not discriminate on the grounds of race, color, sex, national origin, religion, age, or disability in the selection and retention of sub-applicants, including procurements of materials and leases of equipment. CONTRACTOR shall not participate either directly or indirectly in the discrimination prohibited by Section 21.5 of the Regulations, including employment practices when the agreement covers a program set forth in Appendix B of the Regulations. c. Solicitations for Sub-agreements, Including Procurements of Materials and Equipment: In all solicitations either by competitive bidding or negotiation made by CONTRACTOR for work to be performed under a Sub- agreement, including procurements of materials or leases of equipment, each potential sub-applicant or supplier shall be notified by CONTRACTOR of the CONTRACTOR’S obligations under this Agreement and the Regulations relative to nondiscrimination on the grounds of race, color, or national origin. d. Information and Reports: CONTRACTOR shall provide all information and reports required by the Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC Local Assistance Procedures Manual Exhibit 12-G Required Federal-Aid Contract Language Page 15 of 21 October 2023 Regulations, or directives issued pursuant thereto, and shall permit access to its books, records, accounts, other sources of information, and its facilities as may be determined by the recipient or FHWA to be pertinent to ascertain compliance with such Regulations or directives.

The following provision is adopted from 23 CFR Part 230, Subpart A, Appendix A, with appropriate revisions to conform to the U.S. Department of Labor (US DOL) and FHWA requirements. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 2 1. Equal Employment Opportunity: Equal Employment Opportunity (EEO) requirements not to discriminate and to take affirmative action to assure equal opportunity as set forth under laws, executive orders, rules, regulations (see 28 CFR Part 35, 29 CFR Part 1630, 29 CFR Parts 1625-1627, 41 CFR Part 60 and 49 CFR Part 27) and orders of the Secretary of Labor as modified by the provisions prescribed herein, and imposed pursuant to 23 U.S.C. 140, shall constitute the EEO and specific affirmative action standards for the contractor's project activities under this contract. The provisions of the Americans with Disabilities Act of 1990 (42 U.S.C. 12101 et seq.) set forth under 28 CFR Part 35 and 29 CFR Part 1630 are incorporated by reference in this contract. In the execution of this contract, the contractor agrees to comply with the following minimum specific requirement activities of EEO: a. The contractor will work with the contracting agency and the Federal Government to ensure that it has made every good faith effort to provide equal opportunity with respect to all of its terms and conditions of employment and in their review of activities under the contract. 23 CFR 230.409 (g)(4) & (5). b. The contractor will accept as its operating policy the following statement: "It is the policy of this Company to assure that applicants are employed, and that employees are treated during employment, without regard to their race, religion, sex, sexual orientation, gender identity, color, national origin, age or disability. Such action shall include: employment, upgrading, demotion, or transfer; recruitment or recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship, pre-apprenticeship, and/or on-the-job training." 2. EEO Officer: The contractor will designate and make known to the contracting officers an EEO Officer who will have the responsibility for and must be capable of effectively administering and promoting an active EEO program and who must be assigned adequate authority and responsibility to do so. 3. Dissemination of Policy: All members of the contractor's staff who are authorized to hire, supervise, promote, and discharge employees, or who recommend such action or are substantially involved in such action, will be made fully cognizant of and will implement the contractor's EEO policy and contractual responsibilities to provide EEO in each grade and classification of employment. To ensure that the above agreement will be met, the following actions will be taken as a minimum: a. Periodic meetings of supervisory and personnel office employees will be conducted before the start of work and then not less often than once every six months, at which time the contractor's EEO policy and its implementation will be reviewed and explained. The meetings will be conducted by the EEO Officer or other knowledgeable company official. b. All new supervisory or personnel office employees will be given a thorough indoctrination by the EEO Officer, covering all major aspects of the contractor's EEO obligations within thirty days following their reporting for duty with the contractor. c. All personnel who are engaged in direct recruitment for the project will be instructed by the EEO Officer in the contractor's procedures for locating and hiring minorities and women. d. Notices and posters setting forth the contractor's EEO policy will be placed in areas readily accessible to employees, applicants for employment and potential employees. e. The contractor's EEO policy and the procedures to implement such policy will be brought to the attention of employees by means of meetings, employee handbooks, or other appropriate means. 4. Recruitment: When advertising for employees, the contractor will include in all advertisements for employees the notation: "An Equal Opportunity Employer." All such advertisements will be placed in publications having a large circulation among minorities and women in the area from which the project work force would normally be derived. a. The contractor will, unless precluded by a valid bargaining agreement, conduct systematic and direct recruitment through public and private employee referral sources likely to yield qualified minorities and women. To meet this requirement, the contractor will identify sources of potential minority group employees and establish with such identified sources procedures whereby minority and women applicants may be referred to the contractor for employment consideration. b. In the event the contractor has a valid bargaining agreement providing for exclusive hiring hall referrals, the contractor is expected to observe the provisions of that agreement to the extent that the system meets the contractor's compliance with EEO contract provisions. Where implementation of such an agreement has the effect of discriminating against minorities or women, or obligates the contractor to do the same, such implementation violates Federal nondiscrimination provisions. c. The contractor will encourage its present employees to refer minorities and women as applicants for employment. Information and procedures with regard to referring such applicants will be discussed with employees. 5. Personnel Actions: Wages, working conditions, and employee benefits shall be established and administered, and personnel actions of every type, including hiring, upgrading, promotion, transfer, demotion, layoff, and termination, shall be taken without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age or disability. The following procedures shall be followed: a. The contractor will conduct periodic inspections of project sites to ensure that working conditions and employee facilities do not indicate discriminatory treatment of project site personnel. b. The contractor will periodically evaluate the spread of wages paid within each classification to determine any evidence of discriminatory wage practices. c. The contractor will periodically review selected personnel actions in depth to determine whether there is evidence of discrimination. Where evidence is found, the contractor will promptly take corrective action. If the review indicates that the discrimination may extend beyond the actions reviewed, such corrective action shall include all affected persons. d. The contractor will promptly investigate all complaints of alleged discrimination made to the contractor in connection with its obligations under this contract, will attempt to resolve such complaints, and will take appropriate corrective action Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 3 within a reasonable time. If the investigation indicates that the discrimination may affect persons other than the complainant, such corrective action shall include such other persons. Upon completion of each investigation, the contractor will inform every complainant of all of their avenues of appeal. 6. Training and Promotion: a. The contractor will assist in locating, qualifying, and increasing the skills of minorities and women who are applicants for employment or current employees. Such efforts should be aimed at developing full journey level status employees in the type of trade or job classification involved. b. Consistent with the contractor's work force requirements and as permissible under Federal and State regulations, the contractor shall make full use of training programs (i.e., apprenticeship and on-the-job training programs for the geographical area of contract performance). In the event a special provision for training is provided under this contract, this subparagraph will be superseded as indicated in the special provision. The contracting agency may reserve training positions for persons who receive welfare assistance in accordance with 23 U.S.C. 140(a). c. The contractor will advise employees and applicants for employment of available training programs and entrance requirements for each. d. The contractor will periodically review the training and promotion potential of employees who are minorities and women and will encourage eligible employees to apply for such training and promotion. 7. Unions: If the contractor relies in whole or in part upon unions as a source of employees, the contractor will use good faith efforts to obtain the cooperation of such unions to increase opportunities for minorities and women. 23 CFR 230.409. Actions by the contractor, either directly or through a contractor's association acting as agent, will include the procedures set forth below: a. The contractor will use good faith efforts to develop, in cooperation with the unions, joint training programs aimed toward qualifying more minorities and women for membership in the unions and increasing the skills of minorities and women so that they may qualify for higher paying employment. b. The contractor will use good faith efforts to incorporate an EEO clause into each union agreement to the end that such union will be contractually bound to refer applicants without regard to their race, color, religion, sex, sexual orientation, gender identity, national origin, age, or disability. c. The contractor is to obtain information as to the referral practices and policies of the labor union except that to the extent such information is within the exclusive possession of the labor union and such labor union refuses to furnish such information to the contractor, the contractor shall so certify to the contracting agency and shall set forth what efforts have been made to obtain such information. d. In the event the union is unable to provide the contractor with a reasonable flow of referrals within the time limit set forth in the collective bargaining agreement, the contractor will, through independent recruitment efforts, fill the employment vacancies without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, or disability; making full efforts to obtain qualified and/or qualifiable minorities and women. The failure of a union to provide sufficient referrals (even though it is obligated to provide exclusive referrals under the terms of a collective bargaining agreement) does not relieve the contractor from the requirements of this paragraph. In the event the union referral practice prevents the contractor from meeting the obligations pursuant to Executive Order 11246, as amended, and these special provisions, such contractor shall immediately notify the contracting agency. 8. Reasonable Accommodation for Applicants / Employees with Disabilities: The contractor must be familiar with the requirements for and comply with the Americans with Disabilities Act and all rules and regulations established thereunder. Employers must provide reasonable accommodation in all employment activities unless to do so would cause an undue hardship. 9. Selection of Subcontractors, Procurement of Materials and Leasing of Equipment: The contractor shall not discriminate on the grounds of race, color, religion, sex, sexual orientation, gender identity, national origin, age, or disability in the selection and retention of subcontractors, including procurement of materials and leases of equipment. The contractor shall take all necessary and reasonable steps to ensure nondiscrimination in the administration of this contract. a. The contractor shall notify all potential subcontractors, suppliers, and lessors of their EEO obligations under this contract. b. The contractor will use good faith efforts to ensure subcontractor compliance with their EEO obligations. 10. Assurances Required: a. The requirements of 49 CFR Part 26 and the State DOT’s FHWA-approved Disadvantaged Business Enterprise (DBE) program are incorporated by reference. b. The contractor, subrecipient or subcontractor shall not discriminate on the basis of race, color, national origin, or sex in the performance of this contract. The contractor shall carry out applicable requirements of 49 CFR part 26 in the award and administration of DOT-assisted contracts. Failure by the contractor to carry out these requirements is a material breach of this contract, which may result in the termination of this contract or such other remedy as the recipient deems appropriate, which may include, but is not limited to: (1) Withholding monthly progress payments; (2) Assessing sanctions; (3) Liquidated damages; and/or (4) Disqualifying the contractor from future bidding as non-responsible. c. The Title VI and nondiscrimination provisions of U.S. DOT Order 1050.2A at Appendixes A and E are incorporated by reference. 49 CFR Part 21. 11. Records and Reports: The contractor shall keep such records as necessary to document compliance with the EEO requirements. Such records shall be retained for a period of three years following the date of the final payment to the contractor for all contract work and shall be available at reasonable times and places for inspection by authorized representatives of the contracting agency and the FHWA. a. The records kept by the contractor shall document the following: Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 4 (1) The number and work hours of minority and non-minority group members and women employed in each work classification on the project; (2) The progress and efforts being made in cooperation with unions, when applicable, to increase employment opportunities for minorities and women; and (3) The progress and efforts being made in locating, hiring, training, qualifying, and upgrading minorities and women. b. The contractors and subcontractors will submit an annual report to the contracting agency each July for the duration of the project indicating the number of minority, women, and non-minority group employees currently engaged in each work classification required by the contract work. This information is to be reported on Form FHWA-1391. The staffing data should represent the project work force on board in all or any part of the last payroll period preceding the end of July. If on-the-job training is being required by special provision, the contractor will be required to collect and report training data. The employment data should reflect the work force on board during all or any part of the last payroll period preceding the end of July. III. NONSEGREGATED FACILITIES This provision is applicable to all Federal-aid construction contracts and to all related construction subcontracts of more than $10,000. 41 CFR 60-1.5. As prescribed by 41 CFR 60-1.8, the contractor must ensure that facilities provided for employees are provided in such a manner that segregation on the basis of race, color, religion, sex, sexual orientation, gender identity, or national origin cannot result. The contractor may neither require such segregated use by written or oral policies nor tolerate such use by employee custom. The contractor's obligation extends further to ensure that its employees are not assigned to perform their services at any location under the contractor's control where the facilities are segregated. The term "facilities" includes waiting rooms, work areas, restaurants and other eating areas, time clocks, restrooms, washrooms, locker rooms and other storage or dressing areas, parking lots, drinking fountains, recreation or entertainment areas, transportation, and housing provided for employees. The contractor shall provide separate or single-user restrooms and necessary dressing or sleeping areas to assure privacy between sexes. IV. DAVIS-BACON AND RELATED ACT PROVISIONS This section is applicable to all Federal-aid construction projects exceeding $2,000 and to all related subcontracts and lower-tier subcontracts (regardless of subcontract size), in accordance with 29 CFR 5.5. The requirements apply to all projects located within the right-of-way of a roadway that is functionally classified as Federal-aid highway. 23 U.S.C. 113. This excludes roadways functionally classified as local roads or rural minor collectors, which are exempt. 23 U.S.C. 101. Where applicable law requires that projects be treated as a project on a Federal-aid highway, the provisions of this subpart will apply regardless of the location of the project. Examples include: Surface Transportation Block Grant Program projects funded under 23 U.S.C. 133 [excluding recreational trails projects], the Nationally Significant Freight and Highway Projects funded under 23 U.S.C. 117, and National Highway Freight Program projects funded under 23 U.S.C. 167. The following provisions are from the U.S. Department of Labor regulations in 29 CFR 5.5 “Contract provisions and related matters” with minor revisions to conform to the FHWA-1273 format and FHWA program requirements. 1. Minimum wages (29 CFR 5.5) a. Wage rates and fringe benefits. All laborers and mechanics employed or working upon the site of the work (or otherwise working in construction or development of the project under a development statute), will be paid unconditionally and not less often than once a week, and without subsequent deduction or rebate on any account (except such payroll deductions as are permitted by regulations issued by the Secretary of Labor under the Copeland Act (29 CFR part 3)), the full amount of basic hourly wages and bona fide fringe benefits (or cash equivalents thereof) due at time of payment computed at rates not less than those contained in the wage determination of the Secretary of Labor which is attached hereto and made a part hereof, regardless of any contractual relationship which may be alleged to exist between the contractor and such laborers and mechanics. As provided in paragraphs (d) and (e) of 29 CFR 5.5, the appropriate wage determinations are effective by operation of law even if they have not been attached to the contract. Contributions made or costs reasonably anticipated for bona fide fringe benefits under the Davis-Bacon Act (40 U.S.C. 3141(2)(B)) on behalf of laborers or mechanics are considered wages paid to such laborers or mechanics, subject to the provisions of paragraph 1.e. of this section; also, regular contributions made or costs incurred for more than a weekly period (but not less often than quarterly) under plans, funds, or programs which cover the particular weekly period, are deemed to be constructively made or incurred during such weekly period. Such laborers and mechanics must be paid the appropriate wage rate and fringe benefits on the wage determination for the classification(s) of work actually performed, without regard to skill, except as provided in paragraph 4. of this section. Laborers or mechanics performing work in more than one classification may be compensated at the rate specified for each classification for the time actually worked therein: Provided, That the employer's payroll records accurately set forth the time spent in each classification in which work is performed. The wage determination (including any additional classifications and wage rates conformed under paragraph 1.c. of this section) and the Davis-Bacon poster (WH–1321) must be posted at all times by the contractor and its subcontractors at the site of the work in a prominent and accessible place where it can be easily seen by the workers. b. Frequently recurring classifications. (1) In addition to wage and fringe benefit rates that have been determined to be prevailing under the procedures set forth in 29 CFR part 1, a wage determination may contain, pursuant to § 1.3(f), wage and fringe benefit rates for classifications of laborers and mechanics for which conformance requests are regularly submitted pursuant to paragraph 1.c. of this section, provided that: (i) The work performed by the classification is not performed by a classification in the wage determination for which a prevailing wage rate has been determined; Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 5 (ii) The classification is used in the area by the construction industry; and (iii) The wage rate for the classification bears a reasonable relationship to the prevailing wage rates contained in the wage determination. (2) The Administrator will establish wage rates for such classifications in accordance with paragraph 1.c.(1)(iii) of this section. Work performed in such a classification must be paid at no less than the wage and fringe benefit rate listed on the wage determination for such classification. c. Conformance. (1) The contracting officer must require that any class of laborers or mechanics, including helpers, which is not listed in the wage determination and which is to be employed under the contract be classified in conformance with the wage determination. Conformance of an additional classification and wage rate and fringe benefits is appropriate only when the following criteria have been met: (i) The work to be performed by the classification requested is not performed by a classification in the wage determination; and (ii) The classification is used in the area by the construction industry; and (iii) The proposed wage rate, including any bona fide fringe benefits, bears a reasonable relationship to the wage rates contained in the wage determination. (2) The conformance process may not be used to split, subdivide, or otherwise avoid application of classifications listed in the wage determination. (3) If the contractor and the laborers and mechanics to be employed in the classification (if known), or their representatives, and the contracting officer agree on the classification and wage rate (including the amount designated for fringe benefits where appropriate), a report of the action taken will be sent by the contracting officer by email to DBAconformance@dol.gov. The Administrator, or an authorized representative, will approve, modify, or disapprove every additional classification action within 30 days of receipt and so advise the contracting officer or will notify the contracting officer within the 30–day period that additional time is necessary. (4) In the event the contractor, the laborers or mechanics to be employed in the classification or their representatives, and the contracting officer do not agree on the proposed classification and wage rate (including the amount designated for fringe benefits, where appropriate), the contracting officer will, by email to DBAconformance@dol.gov, refer the questions, including the views of all interested parties and the recommendation of the contracting officer, to the Administrator for determination. The Administrator, or an authorized representative, will issue a determination within 30 days of receipt and so advise the contracting officer or will notify the contracting officer within the 30–day period that additional time is necessary. (5) The contracting officer must promptly notify the contractor of the action taken by the Wage and Hour Division under paragraphs 1.c.(3) and (4) of this section. The contractor must furnish a written copy of such determination to each affected worker or it must be posted as a part of the wage determination. The wage rate (including fringe benefits where appropriate) determined pursuant to paragraph 1.c.(3) or (4) of this section must be paid to all workers performing work in the classification under this contract from the first day on which work is performed in the classification. d. Fringe benefits not expressed as an hourly rate. Whenever the minimum wage rate prescribed in the contract for a class of laborers or mechanics includes a fringe benefit which is not expressed as an hourly rate, the contractor may either pay the benefit as stated in the wage determination or may pay another bona fide fringe benefit or an hourly cash equivalent thereof. e. Unfunded plans. If the contractor does not make payments to a trustee or other third person, the contractor may consider as part of the wages of any laborer or mechanic the amount of any costs reasonably anticipated in providing bona fide fringe benefits under a plan or program, Provided, That the Secretary of Labor has found, upon the written request of the contractor, in accordance with the criteria set forth in § 5.28, that the applicable standards of the Davis-Bacon Act have been met. The Secretary of Labor may require the contractor to set aside in a separate account assets for the meeting of obligations under the plan or program. f. Interest. In the event of a failure to pay all or part of the wages required by the contract, the contractor will be required to pay interest on any underpayment of wages. 2. Withholding (29 CFR 5.5) a. Withholding requirements. The contracting agency may, upon its own action, or must, upon written request of an authorized representative of the Department of Labor, withhold or cause to be withheld from the contractor so much of the accrued payments or advances as may be considered necessary to satisfy the liabilities of the prime contractor or any subcontractor for the full amount of wages and monetary relief, including interest, required by the clauses set forth in this section for violations of this contract, or to satisfy any such liabilities required by any other Federal contract, or federally assisted contract subject to Davis-Bacon labor standards, that is held by the same prime contractor (as defined in § 5.2). The necessary funds may be withheld from the contractor under this contract, any other Federal contract with the same prime contractor, or any other federally assisted contract that is subject to Davis-Bacon labor standards requirements and is held by the same prime contractor, regardless of whether the other contract was awarded or assisted by the same agency, and such funds may be used to satisfy the contractor liability for which the funds were withheld. In the event of a contractor's failure to pay any laborer or mechanic, including any apprentice or helper working on the site of the work all or part of the wages required by the contract, or upon the contractor's failure to submit the required records as discussed in paragraph 3.d. of this section, the contracting agency may on its own initiative and after written notice to the contractor, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds until such violations have ceased. b. Priority to withheld funds. The Department has priority to funds withheld or to be withheld in accordance with paragraph Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 6 2.a. of this section or Section V, paragraph 3.a., or both, over claims to those funds by: (1) A contractor's surety(ies), including without limitation performance bond sureties and payment bond sureties; (2) A contracting agency for its reprocurement costs; (3) A trustee(s) (either a court-appointed trustee or a U.S. trustee, or both) in bankruptcy of a contractor, or a contractor's bankruptcy estate; (4) A contractor's assignee(s); (5) A contractor's successor(s); or (6) A claim asserted under the Prompt Payment Act, 31 U.S.C. 3901–3907. 3. Records and certified payrolls (29 CFR 5.5) a. Basic record requirements (1) Length of record retention. All regular payrolls and other basic records must be maintained by the contractor and any subcontractor during the course of the work and preserved for all laborers and mechanics working at the site of the work (or otherwise working in construction or development of the project under a development statute) for a period of at least 3 years after all the work on the prime contract is completed. (2) Information required. Such records must contain the name; Social Security number; last known address, telephone number, and email address of each such worker; each worker's correct classification(s) of work actually performed; hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in 40 U.S.C. 3141(2)(B) of the Davis-Bacon Act); daily and weekly number of hours actually worked in total and on each covered contract; deductions made; and actual wages paid. (3) Additional records relating to fringe benefits. Whenever the Secretary of Labor has found under paragraph 1.e. of this section that the wages of any laborer or mechanic include the amount of any costs reasonably anticipated in providing benefits under a plan or program described in 40 U.S.C. 3141(2)(B) of the Davis-Bacon Act, the contractor must maintain records which show that the commitment to provide such benefits is enforceable, that the plan or program is financially responsible, and that the plan or program has been communicated in writing to the laborers or mechanics affected, and records which show the costs anticipated or the actual cost incurred in providing such benefits. (4) Additional records relating to apprenticeship. Contractors with apprentices working under approved programs must maintain written evidence of the registration of apprenticeship programs, the registration of the apprentices, and the ratios and wage rates prescribed in the applicable programs. b. Certified payroll requirements (1) Frequency and method of submission. The contractor or subcontractor must submit weekly, for each week in which any DBA- or Related Acts-covered work is performed, certified payrolls to the contracting agency. The prime contractor is responsible for the submission of all certified payrolls by all subcontractors. A contracting agency or prime contractor may permit or require contractors to submit certified payrolls through an electronic system, as long as the electronic system requires a legally valid electronic signature; the system allows the contractor, the contracting agency, and the Department of Labor to access the certified payrolls upon request for at least 3 years after the work on the prime contract has been completed; and the contracting agency or prime contractor permits other methods of submission in situations where the contractor is unable or limited in its ability to use or access the electronic system. (2) Information required. The certified payrolls submitted must set out accurately and completely all of the information required to be maintained under paragraph 3.a.(2) of this section, except that full Social Security numbers and last known addresses, telephone numbers, and email addresses must not be included on weekly transmittals. Instead, the certified payrolls need only include an individually identifying number for each worker ( e.g., the last four digits of the worker's Social Security number). The required weekly certified payroll information may be submitted using Optional Form WH–347 or in any other format desired. Optional Form WH–347 is available for this purpose from the Wage and Hour Division website at https://www.dol.gov/sites/dolgov/files/WHD/legacy/files/wh347/.pdf or its successor website. It is not a violation of this section for a prime contractor to require a subcontractor to provide full Social Security numbers and last known addresses, telephone numbers, and email addresses to the prime contractor for its own records, without weekly submission by the subcontractor to the contracting agency. (3) Statement of Compliance. Each certified payroll submitted must be accompanied by a “Statement of Compliance,” signed by the contractor or subcontractor, or the contractor's or subcontractor's agent who pays or supervises the payment of the persons working on the contract, and must certify the following: (i) That the certified payroll for the payroll period contains the information required to be provided under paragraph 3.b. of this section, the appropriate information and basic records are being maintained under paragraph 3.a. of this section, and such information and records are correct and complete; (ii) That each laborer or mechanic (including each helper and apprentice) working on the contract during the payroll period has been paid the full weekly wages earned, without rebate, either directly or indirectly, and that no deductions have been made either directly or indirectly from the full wages earned, other than permissible deductions as set forth in 29 CFR part 3; and (iii) That each laborer or mechanic has been paid not less than the applicable wage rates and fringe benefits or cash equivalents for the classification(s) of work actually performed, as specified in the applicable wage determination incorporated into the contract. (4) Use of Optional Form WH–347. The weekly submission of a properly executed certification set forth on the reverse side of Optional Form WH–347 will satisfy the requirement for submission of the “Statement of Compliance” required by paragraph 3.b.(3) of this section. Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 7 (5) Signature. The signature by the contractor, subcontractor, or the contractor's or subcontractor's agent must be an original handwritten signature or a legally valid electronic signature. (6) Falsification. The falsification of any of the above certifications may subject the contractor or subcontractor to civil or criminal prosecution under 18 U.S.C. 1001 and 31 U.S.C. 3729. (7) Length of certified payroll retention. The contractor or subcontractor must preserve all certified payrolls during the course of the work and for a period of 3 years after all the work on the prime contract is completed. c. Contracts, subcontracts, and related documents. The contractor or subcontractor must maintain this contract or subcontract and related documents including, without limitation, bids, proposals, amendments, modifications, and extensions. The contractor or subcontractor must preserve these contracts, subcontracts, and related documents during the course of the work and for a period of 3 years after all the work on the prime contract is completed. d. Required disclosures and access (1) Required record disclosures and access to workers. The contractor or subcontractor must make the records required under paragraphs 3.a. through 3.c. of this section, and any other documents that the contracting agency, the State DOT, the FHWA, or the Department of Labor deems necessary to determine compliance with the labor standards provisions of any of the applicable statutes referenced by § 5.1, available for inspection, copying, or transcription by authorized representatives of the contracting agency, the State DOT, the FHWA, or the Department of Labor, and must permit such representatives to interview workers during working hours on the job. (2) Sanctions for non-compliance with records and worker access requirements. If the contractor or subcontractor fails to submit the required records or to make them available, or refuses to permit worker interviews during working hours on the job, the Federal agency may, after written notice to the contractor, sponsor, applicant, owner, or other entity, as the case may be, that maintains such records or that employs such workers, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds. Furthermore, failure to submit the required records upon request or to make such records available, or to permit worker interviews during working hours on the job, may be grounds for debarment action pursuant to § 5.12. In addition, any contractor or other person that fails to submit the required records or make those records available to WHD within the time WHD requests that the records be produced will be precluded from introducing as evidence in an administrative proceeding under 29 CFR part 6 any of the required records that were not provided or made available to WHD. WHD will take into consideration a reasonable request from the contractor or person for an extension of the time for submission of records. WHD will determine the reasonableness of the request and may consider, among other things, the location of the records and the volume of production. (3) Required information disclosures. Contractors and subcontractors must maintain the full Social Security number and last known address, telephone number, and email address of each covered worker, and must provide them upon request to the contracting agency, the State DOT, the FHWA, the contractor, or the Wage and Hour Division of the Department of Labor for purposes of an investigation or other compliance action. 4. Apprentices and equal employment opportunity (29 CFR 5.5) a. Apprentices (1) Rate of pay. Apprentices will be permitted to work at less than the predetermined rate for the work they perform when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the U.S. Department of Labor, Employment and Training Administration, Office of Apprenticeship (OA), or with a State Apprenticeship Agency recognized by the OA. A person who is not individually registered in the program, but who has been certified by the OA or a State Apprenticeship Agency (where appropriate) to be eligible for probationary employment as an apprentice, will be permitted to work at less than the predetermined rate for the work they perform in the first 90 days of probationary employment as an apprentice in such a program. In the event the OA or a State Apprenticeship Agency recognized by the OA withdraws approval of an apprenticeship program, the contractor will no longer be permitted to use apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is approved. (2) Fringe benefits. Apprentices must be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the apprenticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage determination for the applicable classification. If the Administrator determines that a different practice prevails for the applicable apprentice classification, fringe benefits must be paid in accordance with that determination. (3) Apprenticeship ratio. The allowable ratio of apprentices to journeyworkers on the job site in any craft classification must not be greater than the ratio permitted to the contractor as to the entire work force under the registered program or the ratio applicable to the locality of the project pursuant to paragraph 4.a.(4) of this section. Any worker listed on a payroll at an apprentice wage rate, who is not registered or otherwise employed as stated in paragraph 4.a.(1) of this section, must be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under this section must be paid not less than the applicable wage rate on the wage determination for the work actually performed. (4) Reciprocity of ratios and wage rates. Where a contractor is performing construction on a project in a locality other than the locality in which its program is registered, the ratios and wage rates (expressed in percentages of the journeyworker's hourly rate) applicable within the locality in which the construction is being performed must be observed. If there is no applicable ratio or wage rate for the locality of the project, the ratio and wage rate specified in the contractor's registered program must be observed. b. Equal employment opportunity. The use of apprentices and journeyworkers under this part must be in conformity with Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 8 the equal employment opportunity requirements of Executive Order 11246, as amended, and 29 CFR part 30. c. Apprentices and Trainees (programs of the U.S. DOT). Apprentices and trainees working under apprenticeship and skill training programs which have been certified by the Secretary of Transportation as promoting EEO in connection with Federal-aid highway construction programs are not subject to the requirements of paragraph 4 of this Section IV. 23 CFR 230.111(e)(2). The straight time hourly wage rates for apprentices and trainees under such programs will be established by the particular programs. The ratio of apprentices and trainees to journeyworkers shall not be greater than permitted by the terms of the particular program. 5. Compliance with Copeland Act requirements. The contractor shall comply with the requirements of 29 CFR part 3, which are incorporated by reference in this contract as provided in 29 CFR 5.5. 6. Subcontracts. The contractor or subcontractor must insert FHWA-1273 in any subcontracts, along with the applicable wage determination(s) and such other clauses or contract modifications as the contracting agency may by appropriate instructions require, and a clause requiring the subcontractors to include these clauses and wage determination(s) in any lower tier subcontracts. The prime contractor is responsible for the compliance by any subcontractor or lower tier subcontractor with all the contract clauses in this section. In the event of any violations of these clauses, the prime contractor and any subcontractor(s) responsible will be liable for any unpaid wages and monetary relief, including interest from the date of the underpayment or loss, due to any workers of lower-tier subcontractors, and may be subject to debarment, as appropriate. 29 CFR 5.5. 7. Contract termination: debarment. A breach of the contract clauses in 29 CFR 5.5 may be grounds for termination of the contract, and for debarment as a contractor and a subcontractor as provided in 29 CFR 5.12. 8. Compliance with Davis-Bacon and Related Act requirements. All rulings and interpretations of the Davis-Bacon and Related Acts contained in 29 CFR parts 1, 3, and 5 are herein incorporated by reference in this contract as provided in 29 CFR 5.5. 9. Disputes concerning labor standards. As provided in 29 CFR 5.5, disputes arising out of the labor standards provisions of this contract shall not be subject to the general disputes clause of this contract. Such disputes shall be resolved in accordance with the procedures of the Department of Labor set forth in 29 CFR parts 5, 6, and 7. Disputes within the meaning of this clause include disputes between the contractor (or any of its subcontractors) and the contracting agency, the U.S. Department of Labor, or the employees or their representatives. 10. Certification of eligibility. a. By entering into this contract, the contractor certifies that neither it nor any person or firm who has an interest in the contractor's firm is a person or firm ineligible to be awarded Government contracts by virtue of 40 U.S.C. 3144(b) or § 5.12(a). b. No part of this contract shall be subcontracted to any person or firm ineligible for award of a Government contract by virtue of 40 U.S.C. 3144(b) or § 5.12(a). c. The penalty for making false statements is prescribed in the U.S. Code, Title 18 Crimes and Criminal Procedure, 18 U.S.C. 1001. 11. Anti-retaliation. It is unlawful for any person to discharge, demote, intimidate, threaten, restrain, coerce, blacklist, harass, or in any other manner discriminate against, or to cause any person to discharge, demote, intimidate, threaten, restrain, coerce, blacklist, harass, or in any other manner discriminate against, any worker or job applicant for: a. Notifying any contractor of any conduct which the worker reasonably believes constitutes a violation of the DBA, Related Acts, this part, or 29 CFR part 1 or 3; b. Filing any complaint, initiating or causing to be initiated any proceeding, or otherwise asserting or seeking to assert on behalf of themselves or others any right or protection under the DBA, Related Acts, this part, or 29 CFR part 1 or 3; c. Cooperating in any investigation or other compliance action, or testifying in any proceeding under the DBA, Related Acts, this part, or 29 CFR part 1 or 3; or d. Informing any other person about their rights under the DBA, Related Acts, this part, or 29 CFR part 1 or 3. V. CONTRACT WORK HOURS AND SAFETY STANDARDS ACT Pursuant to 29 CFR 5.5(b), the following clauses apply to any Federal-aid construction contract in an amount in excess of $100,000 and subject to the overtime provisions of the Contract Work Hours and Safety Standards Act. These clauses shall be inserted in addition to the clauses required by 29 CFR 5.5(a) or 29 CFR 4.6. As used in this paragraph, the terms laborers and mechanics include watchpersons and guards. 1. Overtime requirements. No contractor or subcontractor contracting for any part of the contract work which may require or involve the employment of laborers or mechanics shall require or permit any such laborer or mechanic in any workweek in which he or she is employed on such work to work in excess of forty hours in such workweek unless such laborer or mechanic receives compensation at a rate not less than one and one-half times the basic rate of pay for all hours worked in excess of forty hours in such workweek. 29 CFR 5.5. 2. Violation; liability for unpaid wages; liquidated damages. In the event of any violation of the clause set forth in paragraph 1. of this section the contractor and any subcontractor responsible therefor shall be liable for the unpaid wages and interest from the date of the underpayment. In addition, such contractor and subcontractor shall be liable to the United States (in the case of work done under contract for the District of Columbia or a territory, to such District or to such territory), for liquidated damages. Such liquidated damages shall be computed with respect to each individual laborer or Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 9 mechanic, including watchpersons and guards, employed in violation of the clause set forth in paragraph 1. of this section, in the sum currently provided in 29 CFR 5.5(b)(2)* for each calendar day on which such individual was required or permitted to work in excess of the standard workweek of forty hours without payment of the overtime wages required by the clause set forth in paragraph 1. of this section. * $31 as of January 15, 2023 (See 88 FR 88 FR 2210) as may be adjusted annually by the Department of Labor, pursuant to the Federal Civil Penalties Inflation Adjustment Act of 1990. 3. Withholding for unpaid wages and liquidated damages a. Withholding process. The FHWA or the contracting agency may, upon its own action, or must, upon written request of an authorized representative of the Department of Labor, withhold or cause to be withheld from the contractor so much of the accrued payments or advances as may be considered necessary to satisfy the liabilities of the prime contractor or any subcontractor for any unpaid wages; monetary relief, including interest; and liquidated damages required by the clauses set forth in this section on this contract, any other Federal contract with the same prime contractor, or any other federally assisted contract subject to the Contract Work Hours and Safety Standards Act that is held by the same prime contractor (as defined in § 5.2). The necessary funds may be withheld from the contractor under this contract, any other Federal contract with the same prime contractor, or any other federally assisted contract that is subject to the Contract Work Hours and Safety Standards Act and is held by the same prime contractor, regardless of whether the other contract was awarded or assisted by the same agency, and such funds may be used to satisfy the contractor liability for which the funds were withheld. b. Priority to withheld funds. The Department has priority to funds withheld or to be withheld in accordance with Section IV paragraph 2.a. or paragraph 3.a. of this section, or both, over claims to those funds by: (1) A contractor's surety(ies), including without limitation performance bond sureties and payment bond sureties; (2) A contracting agency for its reprocurement costs; (3) A trustee(s) (either a court-appointed trustee or a U.S. trustee, or both) in bankruptcy of a contractor, or a contractor's bankruptcy estate; (4) A contractor's assignee(s); (5) A contractor's successor(s); or (6) A claim asserted under the Prompt Payment Act, 31 U.S.C. 3901–3907. 4. Subcontracts. The contractor or subcontractor must insert in any subcontracts the clauses set forth in paragraphs 1. through 5. of this section and a clause requiring the subcontractors to include these clauses in any lower tier subcontracts. The prime contractor is responsible for compliance by any subcontractor or lower tier subcontractor with the clauses set forth in paragraphs 1. through 5. In the event of any violations of these clauses, the prime contractor and any subcontractor(s) responsible will be liable for any unpaid wages and monetary relief, including interest from the date of the underpayment or loss, due to any workers of lower-tier subcontractors, and associated liquidated damages and may be subject to debarment, as appropriate. 5. Anti-retaliation. It is unlawful for any person to discharge, demote, intimidate, threaten, restrain, coerce, blacklist, harass, or in any other manner discriminate against, or to cause any person to discharge, demote, intimidate, threaten, restrain, coerce, blacklist, harass, or in any other manner discriminate against, any worker or job applicant for: a. Notifying any contractor of any conduct which the worker reasonably believes constitutes a violation of the Contract Work Hours and Safety Standards Act (CWHSSA) or its implementing regulations in this part; b. Filing any complaint, initiating or causing to be initiated any proceeding, or otherwise asserting or seeking to assert on behalf of themselves or others any right or protection under CWHSSA or this part; c. Cooperating in any investigation or other compliance action, or testifying in any proceeding under CWHSSA or this part; or d. Informing any other person about their rights under CWHSSA or this part. VI. SUBLETTING OR ASSIGNING THE CONTRACT This provision is applicable to all Federal-aid construction contracts on the National Highway System pursuant to 23 CFR 635.116. 1. The contractor shall perform with its own organization contract work amounting to not less than 30 percent (or a greater percentage if specified elsewhere in the contract) of the total original contract price, excluding any specialty items designated by the contracting agency. Specialty items may be performed by subcontract and the amount of any such specialty items performed may be deducted from the total original contract price before computing the amount of work required to be performed by the contractor's own organization (23 CFR 635.116). a. The term “perform work with its own organization” in paragraph 1 of Section VI refers to workers employed or leased by the prime contractor, and equipment owned or rented by the prime contractor, with or without operators. Such term does not include employees or equipment of a subcontractor or lower tier subcontractor, agents of the prime contractor, or any other assignees. The term may include payments for the costs of hiring leased employees from an employee leasing firm meeting all relevant Federal and State regulatory requirements. Leased employees may only be included in this term if the prime contractor meets all of the following conditions: (based on longstanding interpretation) (1) the prime contractor maintains control over the supervision of the day-to-day activities of the leased employees; (2) the prime contractor remains responsible for the quality of the work of the leased employees; Docusign Envelope ID: EF952C20-29BD-4008-858B-AEBF4E8803CC 10 (3) the prime contractor retains all power to accept or exclude individual employees from work on the project; and (4) the prime contractor remains ultimately responsible for the payment of predetermined minimum wages, the submission of payrolls, statements of compliance and all other Federal regulatory requirements. b. "Specialty Items" shall be construed to be limited to work that requires highly specialized knowledge, abilities, or equipment not ordinarily available in the type of contracting organizations qualified and expected to bid or propose on the contract as a whole and in general are to be limited to minor components of the overall contract. 23 CFR 635.102. 2. Pursuant to 23 CFR 635.116(a), the contract amount upon which the requirements set forth in paragraph (1) of Section VI is computed includes the cost of material and manufactured products which are to be purchased or produced by the contractor under the contract provisions. 3. Pursuant to 23 CFR 635.116(c), the contractor shall furnish (a) a competent superintendent or supervisor who is employed by the firm, has full authority to direct performance of the work in accordance with the contract requirements, and is in charge of all construction operations (regardless of who performs the work) and (b) such other of its own organizational resources (supervision, management, and engineering services) as the contracting officer determines is necessary to assure the performance of the contract. 4. No portion of the contract shall be sublet, assigned or otherwise disposed of except with the written consent of the contracting officer, or authorized representative, and such consent when given shall not be construed to relieve the contractor of any responsibility for the fulfillment of the contract. Written consent will be given only after the contracting agency has assured that each subcontract is evidenced in writing and that it contains all pertinent provisions and requirements of the prime contract. (based on long-standing interpretation of 23 CFR 635.116). 5. The 30-percent self-performance requirement of paragraph (1) is not applicable to design-build contracts; however, contracting agencies may establish their own self-performance requirements. 23 CFR 635.116(d). VII. SAFETY: ACCIDENT PREVENTION This provision is applicable to all Federal-aid construction contracts and to all related subcontracts. 1. In the performance of this contract the contractor shall comply with all applicable Federal, State, and local laws governing safety, health, and sanitation (23 CFR Part 635). The contractor shall provide all safeguards, safety devices and protective equipment and take any other needed actions as it determines, or as the contracting officer may determine, to be reasonably necessary to protect the life and health of employees on the job and the safety of the public and to protect property in connection with the performance of the work covered by the contract. 23 CFR 635.108. 2. It is a condition of this contract, and shall be made a condition of each subcontract, which the contractor enters into pursuant to this contract, that the contractor and any subcontractor shall not permit any employee, in performance of the contract, to work in surroundings or under conditions which are unsanitary, hazardous or dangerous to his/her health or safety, as determined under construction safety and health standards (29 CFR Part 1926) promulgated by the Secretary of Labor, in accordance with Section 107 of the Contract Work Hours and Safety Standards Act (40 U.S.C. 3704). 29 CFR 1926.10. 3. Pursuant to 29 CFR 1926.3, it is a condition of this contract that the Secretary of Labor or authorized representative thereof, shall have right of entry to any site of contract performance to inspect or investigate the matter of compliance with the construction safety and health standards and to carry out the duties of the Secretary under Section 107 of the Contract Work Hours and Safety Standards Act (40 U.S.C. 3704). VIII. FALSE STATEMENTS CONCERNING HIGHWAY PROJECTS This provision is applicable to all Federal-aid construction contracts and to all related subcontracts. In order to assure high quality and durable construction in conformity with approved plans and specifications and a high degree of reliability on statements and representations made by engineers, contractors, suppliers, and workers on Federal-aid highway projects, it is essential that all persons concerned with the project perform their functions as carefully, thoroughly, and honestly as possible. Willful falsification, distortion, or misrepresentation with respect to any facts related to the project is a violation of Federal law. To prevent any misunderstanding regarding the seriousness of these and similar acts, Form FHWA-1022 shall be posted on each Federal-aid highway project (23 CFR Part 635) in one or more places where it is readily available to all persons concerned with the project: 18 U.S.C. 1020 reads as follows: "Whoever, being an officer, agent, or employee of the United States, or of any State or Territory, or whoever, whether a person, association, firm, or corporation, knowingly makes any false statement, false representation, or false report as to the character, quality, quantity, or cost of the material used or to be used, or the quantity or quality of the work performed or to be performed, or the cost thereof in connection with the submission of plans, maps, specifications, contracts, or costs of construction on any highway or related project submitted for approval to the Secretary of Transportation; or Whoever knowingly makes any false statement, false representation, false report or false claim with respect to the character, quality, quantity, or cost of any work performed or to be performed, or materials furnished or to be furnished, in connection with the construction of any highway or related project approved by the Secretary of Transportation; or Whoever knowingly makes any false statement or false representation as to material fact in any statement, certificate, or report submitted pursuant to provisions of the Federal-aid Roads Act approved July 11, 1916, (39 Stat. 355), as amended and supplemented; Shall be fined under this title or imprisoned not more than 5 years or both."
