Include any details necessary to adequately explain the scope and/or operation of the proposed project. You may also include any background information and supporting statements regarding the reasons for, or appropriateness of, the application. Use an addendum sheet if necessary. Description/Explanation: The applicant proposes to demolish one existing two-family home and to develop a two-family, residential air-space condominium project on .16 acre infill site within the Local Coastal Program and the Beach Area Overlay Zone (BAOZ). The site is located at 3648 Carlsbad Blvd. between Juniper and Cherry Avenues. The development of the proposed condominium project requires the processing and approval of a Planned Development Permit, Site Development Plan, Coastal Development Permit, Tentative Parcel Map and two Minor Variances. The Tentative Parcel Map associated with the subdivision is considered minor because it involves the division of land into four or fewer condominiums. Topographically, the site is generally flat with an elevation approximately 49 feet above mean sea level (MSL). The site is developed with one two-family home and does not contain any sensitive vegetation. The proposed project contains one, two-story on grade two-family building. The first floor contains two enclosed 2-car garages, two bedrooms and a great room. Access to the parking garages is from a 20 ft. public alley off Juniper Avenue. One guest parking space is located in front of each garage. Both units are a combination of a single level great-room attached to a two-level townhouse wing containing bedrooms, bathrooms, individual stairs and private elevators, and garages. Both homes have similar floor plans consisting of three bedrooms, and unit-one has approximately 3,400 square feet and unit-2 has approximately 3,600 square feet. The front entries face Carlsbad Blvd. and each unit includes patios or balconies and individual private roof deck areas. The underlying lot will be held in common interest divided between the two airspace condominiums. The common area includes, but is not limited to, the driveway and guest parking area and landscaping. The project is an updated Arts and Crafts Prairie House style architecture. Primary building materials include, exposed architectural grade concrete, Palos Verdes stone and tile veneer, tan stucco, metal clad fascia, and recessed metal clad windows and sliding doors. A standing seam metal roof with a 3: 12 roof pitch covers a portion of the building. A combination of pony-wall and wrought-iron railings are used at the balconies and a decorative wrought iron railing surround the roof deck areas. The project has a height limit of 30 feet and the majority of the two-family airspace condominium project has an overall building height of approximately 30 ft. tall as measured from the existing or finished grade, whichever is lower. A stairway and elevator tower located in the middle of the building, extends to approximately 35 feet in height. Roof structures specifically for the housing of elevators and stairways may be erected above the height limits, provided the enclosed area does not provide additional floor area or be taller than the minimum height required to accommodate or enclose the intended use. The flat roof areas and roof decks are approximately 21 feet in height. P-1(8) Page 1 of 1 Revised 07/10 I' .

This checklist contains measures that are required to be implemented on a project-by-project basis to ensure that the specified emissions targets identified in the Climate Action Plan (CAP) are achieved. Implementation of these measures will ensure that new development is consistent with the CAP's assumption for relevant CAP strategies toward achieving the identified greenhouse gas (GHG) reduction targets. In this manner, a project's incremental contribution to a cumulative GHG emissions effect may be determined not to be cumulatively considerable if it complies with the requirements of the CAP, in accordance with CEQA Guidelines Sections 15064(h)(3), 15130(d), and 15183(b). This checklist is intended to assist project applicants in identifying CAP ordinance requirements and demonstrate how their project fulfills those requirements. This checklist is to be completed and included in applications for new development projects that are subject to discretionary review or require a building permit. APPLICATION SUBMITTAL REQUIREMENTS ..i1111 The completed checklist must be included in the project submittal package or building permit application. Application submittal procedures can be found on the City of Carlsbad website. This checklist is designed to assist the applicant in identifying the minimum CAP-related requirements specific to their project. However, it may be necessary to supplement the completed checklist with supporting materials, calculations or certifications, to demonstrate full compliance with CAP requirements. For example, projects that propose or require a performance approach to comply with energy-related measures will need to attach to this checklist separate calculations and documentation as specified by the ordinances . ..i1111 If an item in the checklist is deemed to be not applicable to a project, or is less than the minimum required by ordinance, an explanation must be provided to the satisfaction of the Planning Division or building official. ..i1111 The requirements in the checklist will be included in the project's conditions of approval or issuance of building permit. ..i1111 Details on CAP ordinance requirements are available on the city's website. P-30 Page 1 of 7 RECF~IVED JUL 1 ~ 2019 CITY OF CARLSBAD PLANNING DIVISION Revised 04/19 City of Carlsbad Climate Action Plan Consistency Checklist STEP 1: LAND USE CONSISTENCY The first step in determining CAP consistency for discretionary development is to assess the project's consistency with the growth projections used in the development of the CAP. This section allows the city to determine a project's consistency with the land use assumptions used in the CAP. Projects found not to be consistent with the CAP's land use assumptions and that are projected to emit at or above the CAP screening threshold of 900 metric tons of CO2 equivalent (MTCO2e) GHG will be subject to a project- specific analysis of GHG emissions' impact on the environment in accordance with the requirements of the California Environmental Quality Act (CEQA). This may result in GHG-reducing mitigation measures applied as a condition of project approval in addition to compliance with the CAP ordinance requirements identified in Step 2 of this checklist. Checklist Item (Check the appropriate box and provide an explanation and supporting documentation for your answer) A Is the proposed project consistent with the existing General Plan land use and specific/master plan or zoning designations? OR, If the proposed project is not consistent with the existing land use plan and zoning designations, does the project include a land use plan and/or specific plan, master plan or zoning designation amendment that would result in an equivalent or less GHG-intensive project when compared to the existing designations? Yes No □ If ''Yes", proceed to Step 2 of the checklist. For the second option under Question A above, provide estimated project-related GHG emissions under both existing and proposed designation(s) for comparison. GHG emissions must be estimated in accordance with the City of Car1sbad Guidance to Demonstrating Consistency with the Climate Action Plan. If "No", proceed to Question B. B. The CAP established a screening threshold of 900 MTCOielyear for new development projects to assist in determining consistency with the CAP. The types and sizes of typical projects listed below have been determined to correspond to the CAP screening threshold. Will the proposed land use change result in the construction of less than any one of the following? • Single-Family Housing: 50 dwelling units • Multi-Family Housing: 70 dwelling units • Office: 35,000 square feet • Retail Store: 11,000 square feet • Grocery Store: 6,300 square feet • Other: If the proposed project is not one of the above types, provide a project-specific GHG emissions analysis to determine whether it is below the 900 MTCOie/year screening threshold. If ''Yes", proceed to Step 2 of the checklist □ □ If "No", the project's GHG impact is potentially significant and must be analyzed in accordance with CEQA. Applicant must prepare a Self-developed GHG emissions reduction program in accordance with the City of Car1sbad Guidance to Demonstrating Consistency with the Climate Action Plan to demonstrate how it would offset the increase in emissions over the existing designations. The project must incorporate each of the applicable measures identified in Step 2 to mitigate cumulative GHG emissions impacts unless the decision maker finds that a measure is infeasible in accordance with California Environmental Quality Act Guidelines Section 15091 . Mitigation in lieu of or in addition to the measures in Step 2 may be required, depending on the results of the project-specific GHG impact analysis. Proceed and complete a project-specific Self-developed GHG emissions reduction program and Step 2 of the Checklist. P-30 Page 2 of 7 Revised 04/19 City of Carlsbad Climate Action Plan Consistency Checklist STEP 2: CAP ORDINANCE COMPLIANCE REQUIREMENTS Completion of this checklist will document a project's compliance with CAP ordinances, and in turn, demonstrate consistency with the applicable measures and actions of the CAP. The compliance requirements in this Step 2 apply to development projects that require a building permit. All other development projects shall implement all emissions-related mitigation measures from the General Plan Update EIR.

Hege Sorrow, AIA TransPacific Architects ATTACHMENT 17 1. Locating Open Recreational Space in Front Yard Setback JUSTIFICATION FOR VARIANCE By law a Variance may be approved only if certain facts are found to exist. Please read these requirements carefully and explain how the proposed project meets each of these facts. Use additional sheets if necessary. Explain what special circumstances are applicable to the subject property, including size, shape, topography, location or surroundings, whereby the strict application of the zoning ordinance deprives such property of privileges enjoyed by other property in the vicinity and under identical zoning classification: The lot is a substandard lot at 6,890 square feet, which falls below the 7,500 square foot minimum lot size. There is a 15 ft. private road easement, a standard utility easement, and a 15 ft. fire lane designation. Because any new vehicle access is denied from Carlsbad Blvd., access to the site is from a 20 ft. wide public alley off Juniper Ave. that terminates at the rear of the site. There, the 15 foot wide private road easement, standard utility easement, and 15 fl. fire lane designation extend across the entire width of the site. This precludes locating the open recreational space in the rear yard. The easements have also resulted in increasing the size of the rear yard from the required 12'-6" to the easement required 15 feet. Explain why the granting of the variance does not constitute a grant of special privileges inconsistent with the limitations upon other properties in the vicinity and zone in which the subject property is located and is subject to any conditions necessary to assure compliance with this finding: The granting of locating the open recreational space in the front-yard setback, directly facing Carlsbad Blvd, where no driveway or vehicle access is allowed, and has a substandard sidewalk and parkway of only 6 feet, and provides the open space with unobstructed ocean views, is not a special privilege based on the substandard lot size, lhe two easements and a fire lane designation. Explain why the granting of the variance does not authorize a use or activity which is not otherwise expressly authorized by the zone regulation governing the subject property: The granting of a variance to locate the required open recreational space in the front-yard setback area does not authorize a use which is not otherwise expressly permitted by the zoning regulations. Therefore, the locating of unit one's open recreational space in the front-yard does not authorize a use or activity which is not authorized by the code. Explain why the granting of the variance is consistent with the general purpose and intent of the General Plan and any applicable specific or Master Plans: The proposed use is a two-family dwelling, consistent with the Residential High (RH) Density designation as discussed above. If located within the coastal zone, explain why the variance is consistent with and implements the requirements of the certified local coastal program and that the variance does not reduce or in any manner adversely affect the protection of coastal resources. P-4 The granting of a variance is consistent with and implements the requirements of the Local Coastal Program and will not have an adverse effect on coastal resources and will have no impacts on sensitive environmental resources. Therefore, granting such a variance will not adversely affect the Local Coastal Program. Page 4 of 4 Revised 04/15 ATTACHMENT 17 DESCRIPTIVE EXPLANATION AND JUSTIFICATION FOR GRANTING A VARIANCE The proposed project is located on Carlsbad Boulevard where all the lots on the entire block have no vehicle access directly onto Carlsbad Blvd. Instead all the lots get their access from alleys, which are accessed from either of the two side streets. The proposed site's access is by means of a rear 20 ft. public alley, which besides serving the project site, also provides access for the lots to the south of the site. The alley itself terminates at the proposed site. There a 15 foot wide private easement extends across the entire rear width of the site. None of the adjoining properties, who have easement rights, currently or historically access their properties from the project site. It's a dead-end private street with no outlet(s}, and that no one but the proposed project owner need to cross in order to access their property. The lot to the north has its access from the adjoining side street. The Planning code essentially only addresses vehicle access from the 'front' street, which in our case, is for all practical purposes, is prohibited. Therefore, the only way then to have any vehicle access is to utilize the rear alley, which is what all but one of the lots on the block already do. Therefore, the rear (alley) access is consistent with the existing pattern of site development. This creates a situation where the 'normal' tendency to locate the required private open recreational space(s) in the rear yard is not possible because that space has significant use restriction which limit the permitted uses to only providing access to the private enclosed garages and the guest pa rking. In addition, the site is blessed with having an outstanding view of the ocean from the front yard. Without the need to provide for a driveway and guest parking, the entire front yard area is now available for use as open recreational area. The proposed design is to locate a 348 square foot 'garden patio', surround by a series of low walled landscape walls that provide visual and acoustical privacy. The proposed open recreational space is only 32 percent of the front-yard setback area. The granting of this variance is in keeping with the spirit and intent of the planning code, makes for good architectural and community engagement designs, and is in keeping with the existing use pattern of similar properties lots fronting on that sect ion of Carlsbad Blvd., to use their front yards as open recreational areas. Who in their right mind, would locate the private recreational space to rear yard, and not take advantage of the view? This variances only allow us to achieve the same uses that are already granted to all the other properties on the block, and the street.

Clearly identi fiable front doors and porches enhance the street scene and create opportunities for greater social interaction within the neighborhood. Building entries and windows should face the street. Front porches, bay windows, courtyards and balconi es are encouraged. Garages Homes should be designed to feature the residence as the prominent part of the str ucture in relation to the street. A variety of garage configurations should be used to improve the street scene. This may include tandem garages, side-loaded garages, front- loaded garages, alley-loaded garages and recessed garages. Street Design An interconnected, modified (grid) street pattern should be incorporated into project designs when there are no topographic or environmental constraints. Interconnected streets provide pedestrians and automobiles many alternative routes to fo llow, disperse traffic and reduce the volume of cars on any one street in the neighborhood. Streets should be designed to provide both vehicular and pedestri an connectivity by minimizing the use of cul- de-sacs. The street network should also be designed to create a safer, more comfortable pedestrian and bicycl ing environment. Local residential streets should have travel and parking lanes, be sufficiently narrow to slow traffic, provide adequate access for emergency and service vehicles and emergency evacuation routes for residents and include parkways with trees to form a pleasing canopy over the street. Local residential streets are the public open space in which children often play and around which neighborhoods interact. Within this context, vehi cular movement should be additionally infl uenced through the use of City-accepted designs for traffic calming measures. Parkways Street trees should be planted in the parkways along all streets. Tree species should be selected to create a unified image for the street, provide an effective canopy, avoid sidewalk damage and minimize water consumption. Pedestrian Walkways Pedestrian walkways should be located along or visible from all streets. Walkways (sidewalks or trails) should provide clear, comfortable and direct access to neighborhood schools, parks/plazas and transit stops. Primary pedestrian routes should be bordered by residential fronts, parks or plazas. Where street connections are not feasible (at the end of cul-de-sacs), pedestrian paths should also be provided.

Policy 44 is geared toward multiple, one-family or multiple two-family developments projects where multiple buildings are proposed in close proximity. The policy does not apply to one, single-family home. However, it technically applies to one, two-family homes. The policy would not apply to a multiple-family building containing three or more units. City Council Policy 44 allows a project to propose an architectural style that complies with the purpose and intent of the policy which states: 'The purpose and intent of the architectural guidelines is t o ensure that a variety of architectural elements are incorporated into sin gle-family homes and two-family structures so that they: a) are visually interesting, b) have sufficient building articulation to reduce their bulk and mass, c) are in scale to their lot size, and d) strongly contribute to the creation of livable neighborhoods.' 1 ATTACHMENT 16 ARCHITECTURAL GUIDELINES 1 . 0 THE ARCHITECTURAL STYLE of the Breakers' View building is an updated version of the Arts & Craft Prairie House Style. The two-story Pallas Verde stone building, ninety- one feet long, has three nearly continuous horizontal bands, at three different vertical locations, and on every building elevations. This strong horizontal elements give structural theme and design unity to each and every building elevation. These long low layered lines reflect the shapes of where land and sea intersect and are expressed in the interplay of roof, balcony and landscape planter wall elements and the vertically of key architectural elements, together producing a dynamic and graceful cohesive architectural design. The first band is located at grade level and is a series of low, exposed architectural-grade concrete landscape- planter walls, which are essential to forming a strong visual foundational-base where the building appears to have organically grow out of the site, (and not just dropped down on a flat lot), and thus integrating the building design and the site design into a unified whole. The second band is the required Policy 44 -Single Story Building Edge. (Guideline #9.c option used) Again, this element is also comprised of three primary parts. The first part, is the 'clerestory awning'. This element is key to setting a human scale to the architecture, and a signature design feature of the Prairie House style -eliminating the 'headers' or short pieces of wall that extend between the top of the doors or windows, and where they meet the ceiling/ floor assembly that is above them. The first floor has a ceiling height of eleven-feet, a floor-to-floor height of twelve-feet, and with eight- foot opening heights at all doors and windows, which leaves a problematic four-foot high section of header- wall. This is resolved by replacing the 'header' with a twelve-inch thick, by eighteen-inch deep, low-roof element or 'clerestory awning roof' element, then replacing the piece of 'short-wall' with clerestory windows, that fill the space between the top of clerestory awing and the bottom of the floor/ ceiling 2 assembly above. The second part of the Single Story Building Edge band, is the cantilevering of the second floor framing out two-feet beyond the exterior walls, thereby creating a first floor roof edge. The eighteen- inch high, two-part, accent colored, and stepped clerestory awning roof fascia assembly integrates the first floor roof with the clerestory awning below and the balcony guardrails above. The third part of the Single Story Building Edge band are the second-floor balcony guardrails, who's color accented wall-caps and wrought iron decorative handrails, provide a ATTACHMENT 16 cohesive design detail, that simultaneously allows for accommodating changes in floor plans and exterior elevations, and still maintains overall architectural design consistency. The third band are the flat-roofs / roof-decks over the second-floor. Repeating the same thickness, profile, color scheme, and cantilever distance as the first floor roof edge, the second floor lower roof lines unifies the massing of building and emphases the horizontal lines of the building. 1 . 1 TH E E NT RY to the project is from Carlsbad Boulevard for pedestrians, vehicles gain access to the garages and guest parking through the rear alley that is entered off Juniper Avenue. There are separate pedestrian decorative walkways extending from the public sidewalk to private covered entry porches for each unit, and each entry is located on separate sides of the building. When viewed from the front, only one unit entry can be seen at time, giving the impression that the building is a single family home. Unit One's entry is on the North side, and Unit Two's entry in on the South side. The entry walkways are separated from the first -floor front-yard recreational view patio by architectural concrete landscape planters that provide both physical and visual privacy from the walkways, as well as Carlsbad Blvd. Both entryways extend from the front street to the rear guest parking and driveway areas. Two pedestrian gates provide access control to the walkways, as a legacy (1926) private driveway access easement precludes providing a driveway access control gate at the public alley, and thereby insuring the complete inability to properly secure the site. 1 . 2 f L O O R P LA N S A N D E L EV AT I O N S The proposed two-family residential air-space condominium project proposes a deviation to the architectural guideline #1 of City Council Policy No.44 which states: All residential projects shall be required to have a minimum number of different floor plans, different front and corresponding matching rear elevations with different color 3 schemes ... , ... 2-4 unit dwellings shall provide 1 floor plan and 2 different elevations. Policy 44 is geared toward multiple, one-family or multiple two-family developments projects where multiple buildings are proposed in close proximity. The policy does not apply to one, single-family home. However, it technically applies to one, two-family homes. The policy would not apply to a multiple-family building containing three or more units. ATTACHMENT 16 City Council Policy 44 allows a project to propose an architectural style that complies with the purpose and intent of the policy which states: 'The purpose and intent of the architectural guidelines is to ensure that a variety of architectural elements are incorporated into single-family homes and two-family structures so that they: a) are visually interesting, b) have sufficient building articulation to reduce their bulk and mass, c) are in scale to their lot size, and d) strongly contribute to the creation of livable neighborhoods.' The proposed deviation is to provide: 1) two different floor plans, and 2) one single integrated exterior elevation design that creates a visual impression of a single two-story single-family home, and not that of a two-story stacked-flat apartment building. The proposed floor plans and elevation designs meet the purpose, intent and all other requirements of the Policy 44. Below are the justifications for the deviation and an illustration of how compliance will be achieved. 1.3 THE FLOOR PLAN for each of the two units is comprised of two parts, a front section of the building that faces directly onto Carlsbad Boulevard with unobstructed white-water ocean views from both units, and a rear section that opens onto a public ally for vehicle access, a driveway for two enclosed garages and guest parking. The front portion of the building is arranged in a two-story 'stacked-flats' configuration. The rear portion of the building is arranged in a two-story, side-by-side, town-house configuration. The stacked flat configuration of the front portion of the building was to insure that both units had full and equal ability to take advantage of the outstanding beach views. Doing this gives each unit the same plus forty-foot wide unobstructed view from their great-rooms, patio or balcony and roof deck. The town-house configuration of the rear portion of the building allows for two side-by-side two-car enclosed garages, first and second floor bedrooms and baths, individual stairs, private elevators, separate roof decks, and most importantly, separate street facing entry walkways with covered entry porches. While the floor plan for rear portion of the building is the same for both units, by necessity, the floor plan for each unit in the front portion must be different to accommodate the separate street entryways, since they are on opposite sides of the building. Unit One's entry in on the north side, and Unit Two's is on the south side. 4 ATTACHMENT 16 1.4 THE EXTERIOR ELEVATIONS as proposed clearly meet the requirements of Policy 44 which states: 'Every house should have a coherent architectural style. All elevat ions of a house, including front, side and rear, should have the same design integrity of forms, details and materials. The discussion above in the Architectural Style section above describes in detail how compliance is to be achieved. But a more significant issue is what consideration should be given for the fact that the project is acting as a buffer between the forty-five foot high, three and one-half stories condo building immediately to the south and the more residential scaled two-story single-family and multiple residential units extending t o the north. 2.0 To minimize the impact of the proposed project on the property immediately adjoining to the north, the higher slopped roof has been setback between seven and twelve feet from the edge of the lower roof, and t hirty-feet from the rear property line. A R C H I T E C T U R A L M A T E R I A L S A N D D E TA I L S Th e proposed two-family building provides covered first level porches, en tryways and patio's, second story ba lconies and third story roof decks. The building has a variety of materials consisting of tan stucco, stone and tile veneer, met al clad wood fascia, recessed metal-clad casement window, entry & sliding doors, and exterior bi-fold doors. A standing seam metal roof with a 3:12 pitch covers a portion of the building.

Residential projects as per Policy 44 require a minimum of four out of the eight following architectural design details. The proposed two-family home incorporates all eight of the design details listed. 1-Second-floor balconies and roof decks have two-part guardrails. Each guardrails has a lower two-foot high wood-framed pony wall, with an attached, eighteen-inch high wrought iron decorative handrail, with an overall total height of forty-two inches. 2-Exposed architectural concrete structural-tower structures, incorporating fireplaces, fire pits and BBQ's. Towers elements extend from grade level through and above both the lower and upper roofs. These design elements create the strong vertical lines that create the visual design tension between the horizontal and vertical architectural elements. 3-Exposed architectural concrete planter walls at finish grade 4-Custom standing seam metal roof with integral concealed gutters 5-Vertical wood, stucco and concrete pilasters that create recessed doors and window wall panels. 6-Exterior wall finishes that include exposed architectural concrete walls, precast concrete wall panels with architectural concrete or textured wood finishes, wood trim and casings at balcony rails, and exterior wood siding and trim elements 7-Wood and concrete accent materials at walls and roofs 8-Stair and elevator towers with roof deck access and mechanical equipment penthouses. 2.2 ROOF DESIGN & HEIGHTS: The proposed design has three different roof levels. The lowest roof level is comprised of the flat roof area, plus the individual roof decks, has a height of 21 feet (maximum height of 24'-0") and an area of 2,030 square feet (45%). The next roof level is the sloped standing seam metal roof with a 3:12 roof pitch, has a maximum height of 30'-0" and an area of 1,768 square feet (40%}. The third roof level is the stair/elevator penthouse roofs. It is a sloped standing seam metal roof with a 3:12 pitch and a maximum height of 35 feet and has the smallest area of the three at 734 square feet (15%}. 6 0 ATTACHMENT 16 2 .3 POLICY 44 -SINGLE STORY BUILDING EDGE: Architectural Guideline No. 9 -C: a single story building edge element with a minimum width of 3 feet wid e, for 40% of the total building perimeter.

WIRE FRAUD ALERT This Notice is not intended to provide legal or professional advice. If you have any questions, please consult with a lawyer. All parties to a real estate transaction are targets for wire fraud and many have lost hundreds of thousands of dollars because they simply relied on the wire instructions received via email, without further verification. If funds are to be wired in conjunction with this real estate transaction, we strongly recommend verbal verification of wire instructions through a known, trusted phone number prior to sending funds. In addition, the following non-exclusive self-protection strategies are recommended to minimize exposure to possible wire fraud. • NEVER RELY on emails purporting to change wire instructions. Parties to a transaction rarely change wire instructions in the course of a transaction. • ALWAYS VERIFY wire instructions, specifically the ABA routing number and account number, by calling the party who sent the instructions to you. DO NOT use the phone number provided in the email containing the instructions, use phone numbers you have called before or can otherwise verify. Obtain the number of relevant parties to the transaction as soon as an escrow account is opened. DO NOT send an email to verify as the email address may be incorrect or the email may be intercepted by the fraudster. • USE COMPLEX EMAIL PASSWORDS that employ a combination of mixed case, numbers, and symbols. Make your passwords greater than eight (8) characters. Also, change your password often and do NOT reuse the same password for other online accounts. • USE MULTI-FACTOR AUTHENTICATION for email accounts. Your email provider or IT staff may have specific instructions on how to implement this feature.

The purpose of the survey is to determine the estimated interior noise levels within the residential structures and recommend mitigation measures for compliance with the California Code of Regulations Title 24 and the City of Carlsbad guidelines and requirements for interior noise. project Location t pescci ptjon The project site is located at 3648 Carlsbad Boulevard, approximately 0.6 miles south of Carlsbad Village Drive and 0.6 miles west of the Interstate 5 (I-5) freeway in the City of Carlsbad, CA. The project vicinity can be seen in Figure 1 on the following page. The project proposes a 2 unit residential development. The project site configuration is provided in Figure 2 on Page 3. The main source for noise is from vehicular traffic from adjacent Carlsbad Boulevard. Acoustjcal Fundamentals Noise is defined as unwanted or annoying sound which interferes with or disrupts normal activities. Exposure to high noise levels has been demonstrated to cause hearing loss. The individual human response to environmental noise is based on the sensitivity of that individual, the type of noise that occurs and when the noise occurs. 4/14/16 1 15143-02 Breakers View Beach House Noise Matthew Castriotta 3648 Carlsbad Blvd., LLC 29888 Sycamore Ridge Road Murrieta, CA 92563 Carlsbad 4/14/16 ATTACHMENT 6 Ldn Contlulllng, /ne,. 42428 Chisolm Trail, Murrieta CA 92562 phone 760-473-1253 Fax 760-689-4943 Figure 1: Project Site Location \ Project Location -.. 2 t l f 15143-02 Breakers View Beach House Noise Matthew Castriotta 3648 Carlsbad Blvd., LLC 29888 Sycamore Ridge Road Murrieta, CA 92563 4/14/16 ATTACHMENT 6 Ldn Conlfu/Hng, lne.. 42428 Chisolm Trail, Murrieta CA 92562 phone 760-473-1253 Fax 760-689-4943 Figure 2: Project Site Configuration CARLSBAD BL VD 3 15143-02 Breakers View Beach House Noise Matthew Castriotta 3648 Carlsbad Blvd., LLC 29888 Sycamore Ridge Road Murrieta, CA 92563 ATTACHMENT 6 Ldn~Hng, lne.. 42428 Chisolm Trail, Murrieta CA 92562 phone 760-473-1253 Fax 760-689-4943 Sound is measured on a logarithmic scale consisting of sound pressure levels known as a decibel (dB). The sounds heard by humans typically do not consist of a single frequency but of a broadband of frequencies having different sound pressure levels. The method for evaluating all the frequencies of the sound is to apply an A-weighting to reflect how the human ear responds to the different sound levels at different frequencies. The A-weighted sound level adequately describes the instantaneous noise whereas the equivalent sound level depicted as Leq represents a steady sound level containing the same total acoustical energy as the actual fluctuating sound level over a given time interval. The Community Noise Equivalent Level (CNEL) is the 24 hour A-weighted average for sound, with corrections for evening and nighttime hours. The corrections require an addition of 5 decibels to sound levels in the evening hours between 7 p.m. and 10 p.m. and an addition of 10 decibels to sound levels at nighttime hours between 10 p.m. and 7 a.m. These additions are made to account for the increased sensitivity during the evening and nighttime hours when sound appears louder. CNEL values do not represent the actual sound level heard at any particular time, but rather represents the total sound exposure. Additionally, Sound Transmission Class (or STC) is an integer rating of how well airborne sound is attenuated by a building partition. STC is widely used to rate interior partitions, ceilings/floors, doors, windows and exterior wall configurations (see ASTM International Classification E413 and E90). The STC number is derived from tested sound attenuation values found at the 1/3 octave band frequencies. These transmission-loss {TL) values are then plotted and compared to a standard reference contour. Acoustical engineers fit these values to the appropriate TL Curve to determine a single STC value found at 500 Hertz. STC is roughly the decibel reduction in noise a partition can provide, abbreviated 'dB'. If an 85 dB sound on one side of a wall is reduced to 50 dB on the other side, that partition is said to have an STC of 35. This number does not apply across the range of frequencies because the STC value is derived from a curve-fit from the tested 1/3 octave band frequencies. Any partition will have less TL at lower frequencies. For example, a wall with an STC of 35 may provide over 40 dB of attenuation at 3000 Hz but only 15 dB of attenuation at 125 Hz. Exterior Noise standards The City of Carlsbad's Noise Element requires that all exterior sensitive areas shall limit noise exposure. For noise sensitive residential land uses, the City has adopted a policy which has 4/14/16 4 15143-02 Breakers View Beach House Noise Matthew Castriotta 3648 Carlsbad Blvd., LLC 29888 Sycamore Ridge Road Murrieta, CA 92563 ATTACHMENT 6 Ldn L:ontluillng, lne.. 42428 Chisolm Trail, Murrieta CA 92562 phone 760-473-1253 Fax 760-689-4943 established a "normally acceptable" exterior noise level goal of 60 dBA CNEL for the outdoor areas and an interior noise level of less than 45 dBA CNEL. For residential properties identified as requiring a noise study, a study shall be prepared by an acoustical professional. This study shall document the projected maximum exterior noise level and mitigate the projected exterior noise level to a maximum allowable noise level as identified in Noise Guideline Manual. Interior Nojse standards California's Title 24 Noise Standards In 1974, the California Commission on Housing and Community Development adopted noise insulation standards for multi-family residential buildings (Title 24, Part 2, California Code of Regulations or CCR). CCR Title 24 establishes standards, based on the U.S. Department of Housing and Urban Development (HUD) requirements, for interior room noise (attributable to outside noise sources). The regulations also specify that acoustical studies must be prepared whenever a multi-family residential or motel/hotel building or structure is proposed to be located near an existing or adopted freeway route, expressway, parkway, major street, thoroughfare, rail line, rapid transit line, or industrial noise source, and where such noise sources create an exterior CNEL (or Ldn) of 60 dBA or greater. Such acoustical analysis must demonstrate that the residence has been designed to limit intruding noise to an interior CNEL (or Ldn) of at least 45 dBA. Analysis procedures Exterior Noise Levels The primary source of noise impacts to the project site will be vehicular noise from adjacent Carlsbad Boulevard. The projected roadway noise levels from vehicular traffic were calculated using the methods in the Highway Noise Model published by the Federal Highway Administration (FHWA Highway Traffic Noise Prediction Model, FHWA·RD-77-108, December, 1978). The FHWA Model uses the traffic volume, vehicle mix, speed, and roadway geometry to compute the equivalent noise level. A spreadsheet calculation was used which computes equivalent noise levels for each of the time periods used in the calculation of CNEL. Weighting these equivalent noise levels and summing them gives the CNEL for the trafficprojections. 4/14/16 5 15143-02 Breakers View Beach House Noise Matthew Castriotta 3648 Carlsbad Blvd., LLC 29888 Sycamore Ridge Road Murrieta, CA 92563 ATTACHMENT 6 Ldn Condu/Hng, lne. 42428 Chisolm Trail, Murrieta CA 92562 phone 760-473-1253 Fax 760-689-4943 Mobile noise levels radiant in an almost oblique fashion from the source and drop off at a rate of 3 dBA for each doubling of distance under hard site conditions and at a rate of 4.5 dBA for soft site conditions. Hard site conditions consist of concrete, asphalt and hard pack dirt wh ile soft site conditions exist in areas having slight grade changes, landscaped areas and vegetation. The future traffic noise model also utilizes the vehicle mix referenced in the City's Noise Guideline Manual of 97.9% Autos, 1.8% Medium Trucks and 0.3% Heavy Trucks for all roadways. The vehicle mix provides the hourly distribution percentages of automobile, medium trucks and heavy trucks for input into the FHWA Model. Carlsbad Boulevard is expected to have 13,700 ADT according to the SANDAG Series 13 Traffic Prediction Model for the year 2035. The speed limit along this segment of Carlsbad Boulevard is 25 MPH. Based on the exterior noise model, the worst-case noise level from the roadway was found to be 63.3 dBA CNEL at the site. The modeling results are shown in Figure 3. No noise barriers, existing structures or topography that may affect noise levels were incorporated in the calculations.

Utilizing the same worst-case noise levels identified above for the building fac;ade the outdoor use area could be exposed to noise levels of 63 .3 dBA CNEL. This noise level is slightly above the normally acceptable level of 60 dBA CNEL but within the conditional compatible levels. As a design feature the project is proposing a solid planter area on the ground level and a solid railing at the second floor balcony that would help shield traffic related noise. To determine the noise level reductions from the solid planter box and railing, the Fresnel Barrier Reduction Calculations were modeled based on distance, source height and receiver elevation. It was found that the shielding would reduce the noise levels at the outdoor use area 3 or more decibels. Therefore, the traffic related noise level would be meet the 60 dBA CNEL goal and no outdoor impacts from the roadways are anticipated. Interior Noise Levels The methodology used to determine the resultant interior noise levels is based upon the exterior noise level minus the sound transmission loss as identified in the American Society of Testing and Materials (ASTM) guidelines: E413 &E90. Standard building construction will provide a noise reduction of approximately 12-15 dBA with a windows open condition and a minimum 20 dBA noise reduction with the windows closed. The exterior noise levels at the proposed structures calculated in terms of dBA are converted to the six octave band sound pressure levels between: 125 -4000 Hertz. Acoustical modeling of the proposed project dwelling units was performed in accordance with the above guidelines and included combining the transmission loss for each of the building components that will reduce the interior noise levels. Building components typically include the windows, exterior doors, and exterior walls. The total noise reduction is dependent upon the transmission loss of each building component, their subsequent surface area, quality of the building/construction materials, a building fac;ade and angle correction. The interior noise level is also dependent on the acoustical energy absorbed within the room based upon the Noise Reduction Coefficients (NRC). NRC is a scalar representation of the amount of sound energy absorbed upon striking a particular surface and the arithmetic value average of sound absorption coefficients indicating a material's ability to absorb sound. The absorption coefficients for individual surface areas such as carpet, drywall and furnishings are used to calculate the interior room effects. The calculated building noise reduction includes 4/14/16 7 15143-02 Breakers View Beach House Noise Matthew Castriotta 3648 Carlsbad Blvd., LLC 29888 Sycamore Ridge Road Murrieta, CA 92563 ATT AC HM ENT 6 Ldn Comlu/Hng, Irie.. 42428 Chisolm Trail, Murrieta CA 92562 phone 760-473-1253 Fax 760-689-4943 both the room absorption characteristics and the transmission loss from the exterior wall assembly. The interior noise reduction calculations were performed using Ldn's interior noise model. The model converts the exterior sound level to octave band frequencies and accounts for the transmission loss, correction factors and room absorption. The floor plans used for this analysis were provided by Transpacific Architects, 2016. The following construction details were utilized for each of the building assemblies to determine the noise reduction characteristics: Exterior walls and roof assemblies must have a Sound Transmission Class (STC) rating of 46 or better. Exterior walls with this rating consist of 2"x4" studs or larger, spaced 16" o.c. with R-13 insulation minimum and an exterior surface of 7/8" cement plaster (stucco). Interior wall and ceiling surfaces shall be at least 1/2" thick gypsum or plaster. Roof assemblies should have a minimum of 1/2" sheathing, R-19 insulation and sealed to prevent noise leaks. Exterior entry doors should be of solid core construction and glass assemblies should be dual- glazed and acoustical sealant applied around the exterior edges. The window and door assemblies are generally the weakest noise reducing component but are the most convenient and cost effective elements to change if additional attenuation is needed. The STC ratings for the glass assemblies and exterior entry doors were calculated in the interior noise model and provided in the findings below. Bathrooms, kitchens, closets and corridors are not required to meet the 45 dBA CNEL standard and therefore were not modeled. All living areas where lower noise levels are essential for conversation and sleep should have carpeting installed; this includes bedrooms. The living and dining rooms were considered to have tile or hardwood flooring and modeling to account for less noise absorption. These rooms and were modeled to determine the interior noise reductions. If the modeled interior noise levels were found to be higher than 45 dBA CNEL in the living areas with the minimum assembly requirements described above additional modeling was performed to determine the minimum STC rating for the glass assemblies to further reduce interior noise levels below the acceptable interior threshold of 45 dBA CNEL. Eiodings The outdoor usable areas will be at or below the City's normally acceptable goal of 60 dBA CNEL with the incorporation of the solid planter and upper level solid rail. The building facade noise levels were determined to be as high as 63.3 dBA CNEL based on the analysis above.

To meet the 45 dBA CNEL interior noise standard, an overall minimum interior noise level reduction of 18-19 dBA CNEL is needed for the proposed project. Therefore a closed window condition is required to reduce interior noise levels to comply with CCR Title 24 and City of Carlsbad requirements. The windows closed condition requires that mechanical ventilation is installed to move air within the structure and control temperatures. The mechanical ventilation must meet the jurisdictional requirements for these dwelling units.

To view the BMP Manual, refer to the Engineering Standards (Volume 5). 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 questionna ire 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. Only one completed and signed questionnaire is required when multiple development applications for the same project are submitted concurrently. -PROJECT INFORMATION PROJECT NAME: PROJECT ID: ADDRESS: 3648 Carlsbad Blvd. APN: 204-232-12 The project is (check one): D New Development 1lf Redevelopment The total proposed disturbed area is: 6,894 ft2 ( 0.16 ) acres The total proposed newly created and/or replaced impervious area is: 4 984 ft2 ( 0.11 ) acres If your project is covered by an approved SWQMP as part of a larger development project, provide the project ID and the SWQMP # of the larger development project: Project ID SWQMP#: Then, go to Step 1 and follow the instructions.

DISCUSSION ~ VICINITY MAP NTS ATTACHMENT 21 bJiA, Inc. land planning, civil engineering, surveying 3 ATTACHMENT 21 PURPOSE AND SCOPE: The purpose of this report is to publish the results of a hydrology and hydraulic analysis for the proposed condominium project at 3648 Carlsbad Boulevard, City of Carlsbad. The proposed project is a 0.16-acre site. The scope is to study the existing and proposed hydrology and hydraulics as it influences the surrounding properties during a 100-year frequency storm event, and make recommendations to intercept, contain and convey QlO0 to the historic point of discharge. PROJECT DESCRIPTION: The project is located at 3648 Carlsbad Boulevard, near the southwest corner of the intersection of Cherry Avenue and Carlsbad Boulevard, in the City of Carlsbad. The project proposes the development of two condominiums with parking areas. The disturbed area is 0.16 acres; the existing si te is 41 % impervious pre-redevelopment (2,859 square feet) and 72% impervious post- development (4 ,993 square feet). The proposed drainage basin matches th e existing drainage basin in terms of overall area and basin limits. Storm flows affecting the site are limited to the rainfall that lands directly on this property. The following table summarizes the existing condition runoff information from the site. Please refer to th e Existing Condition Hydrology Map for existing drainage area. TABLE I-Summary of Existing Condition Peak Flows Discharge Location Drainage Area 100-Year Peak Flow (acres) (cfs) Carlsbad Boulevard 0.16 0.62 The proposed drainage pattern will be similar as the ex1stmg drainage pattern with some modifications to incorporate the Low Impact Development (LID) Best Management Practices (BMPs) into the project design to mimic the impacts on storm water runoff and quality. The proposed runoff from the project is divided into two separate basin areas. 1) Runoff from the two condominium roofs will be captured and conveyed via roof drains to the proposed flow-through planter for storm water treatment. Runoff will be filtered through the media layer and aggregate storage layer before draining via underdrain pipe to a sidewalk underdrain at the southwest corner of the property. The sidewalk underdrain will direct flow south on Carlsbad Boulevard. Flow will then be intercepted by the existing curb inlet on Carlsbad Boulevard near the southwest corner of the property. 2) Runoff from the landscape, concrete sidewalk, and permeable pavement areas will flow to a 4"- dia PVC storm drain system. The permeable pavement areas will provide pollutant control Breakers View Condominiums Project Number Preliminary Drainage Study bJ.tA, Inc. land planning, civil engineering, surveying 4 • ATTACHMENT 21 treatment of the storm water before discharging into the storm drain system. The storm drain system will run along the northern and southern project boundaries and will direct flow into a proposed underground vault in the southeastern corner of the project. The underground vault will be sized to store the anticipated 0100 storm event volume. A sump pump in the underground vault will pump flows west to the flow through planter for treatment based at a maximum of 0.03 cubic feet per second (13.5 gallons per minute). At this rate the drawdown time of the underground vault is 3.5 hours, less than 96 hours. For stormwater runoff greater than a 100-year storm event, a backup pump will start automatically to empty the underground vault. The table below summarizes the expected cumulative 100-year peak flow rate. Please refer to the Proposed Hydrology Map. Per the San Diego County Rainfall Isopluvial maps, the design 100-year rainfall depth for the site area is 2.7 inches. TABLE 2-Summary of Developed Conditions Peak Flows Drainage Area 100-Year Undetained 100-Year Detained Discharge Location Peak Flow Peak Flow (cfs) (acres) (cfs) Carlsbad Boulevard 0.16 0.78 0.60 STUDY METHOD: The method of analysis was based on the Rational Method according to the San Diego County Hydrology Manual (SD HM). Drainage basin areas were determined from the proposed shown on the tentative parcel map. Initial time of concentration of 5 minutes is used for P6 for 100 year storm, see References. Rainfall Intensity= I= 7.44 *(P6)*(Tc) ~-0·645 P6 for 100 year storm = 2.7" In accordance with the County of San Diego standards, runoff coefficients were based on land use and soil type. An appropriate runoff coefficient (C) for each type of land use in the subarea was selected from Table 3-1 of San Diego Hydrology Manual multiplied by the percentage of total area (A) included in that class. The sum of the products for all land uses is the weighted runoff coefficient (2, [CA]). All landscape and pervious pavement areas were considered 0% impervious, and all roof and concrete areas were considered 95% impervious. For the existing condition, all landscape and concrete areas were tabulated and the total existing si te was calculated to be 41 % impervious. A runoff coefficient of 0.55 was assigned for the existing hydrology. For the proposed condition, OMA Breakers View Condominiums Project Number Preliminary Drainage Study bl--tA, Inc. land planning , civil engineering, surveying 5 ATTACHMENT 21 1, which encompasses the roof area draining to the LID planter, is considered 94 % impervious. A runoff coefficient of 0.87 was calculated for DMA l. DMA 2, which encompasses the landscape, concrete sidewalk, and pervious pavement areas draining to the LID planter, is considered 38% impervious. A runoff coefficient of 0.48 was calculated for DMA 2. See the runoff coefficients and impervious area percentages in the Hydrology and Hydraulic Calculations on the following pages. Also refer to the calculations for sizing the underground vault and LID BMP sizing.

This stored runoff can then be pumped to the flow through planter for treatment. Drainage patterns reflected on the Proposed Hydrology Map will increase the total developed runoff due to an increase in impervious area, however routing runoff, increasing the overall Time of Concentration, and implementing a flow-through planter, permeable pavements and a stormwater vault as proposed within this project will decrease the flow rate at the curb outlet on Carlsbad Boulevard. This project is effective at mitigating the potential impacts that development can have on stormwater runoff. By utilizing the proposed LID systems, this project mitigates both the quantity of runoff generated during storm, and the quality of runoff that will ultimately leave the property. It is our professional opinion that the recommendations provided in this report, and the drainage system as proposed effectively intercept, contain, convey, detain and treat the expected storm water runoff generated by this property to mimic pre-redevelopment conditions.

On a topographic base map, outline the overall drainage area boundary, showing adjacent drains, existing and proposed drains, and overland flow paths. ') ,,. .. 3. Verify the accuracy of the drainage map in the field. Divide the drainage area into subareas by locating significant points of interest. These divisions should be based on topography, soil type, and land use. Ensure that an appropriate first subarea is delineated. For natural areas, the first subarea flow path length should be less than or equal to 4,000 feet plus the overland flow length (Table 3-2). For developed areas, the initial subarea flow path length should be consistent with Table 3-2. The topography and slope within the initial subarea should be generally uniform. 4. Working from upstream to downstream, assign a number representing each subarea in the drainage system to each point of interest. Figure 3-8 provides guidelines for node numbers for geographic information system (GIS)-based studies. 5. Measure each subarea in the drainage area to determine its size in acres (A). 6. Determine the length and effective slope of the flow path in each subarea. 7. Identify the soil type for each subarea. 3-20 • I • Study Area SC .. ,··1 I , ~ 17 l..

In determining C for the subarea, use future land use taken from the applicable community plan, Multiple Species Conservation Plan, National Forest land use plan, etc. 9. Calculate the CA value for the subarea. I 0. Calculate the L(CA) value(s) for the subareas upstream of the point(s) of interest. 11. Detennine P6 and P24 for the study using the isopluvial maps provided in Appendix B. If necessary, adjust the value for P6 to be within 45% to 65% of the value for P24. See Section 3.3 for a description of the RM calculation process. 3.3 PERFORMING RATIONAL METHOD CALCULATIONS This section describes the RM calculation process. Using the input data, calculation of peak flows and Tc's should be performed as follows: l. Determine T; for the first subarea. Use Table 3-2 or Figure 3-3 as discussed in Section 3.1.4. If the watershed is natural, the travel time to the downstream end of the first subarea can be added to Ti to obtain the Tc. Refer to paragraph 3.1.4.2 (a). 2. Determine I for the subarea using Figure 3-1. If Ti was less than 5 minutes, use the 5 minute time to determine intensity for calculating the flow. 3. Calculate the peak discharge flow rate for the subarea, where Qp = L(CA) I. In case that the downstream flow rate is less than the upstream flow rate, due to the long travel time that is not offset by the additional subarea runoff, use the upstream peak flow for design purposes until downstream flows increase again. 3-22 San Diego County Hydrology Manual Date: Jun.: 2003 4. Estimate the Ti to the next point of interest. 5. Add the T1 to the previous Tc to obtain a new Tc. Section: Page: ATTACHMENT 21 3 23 of26 6. Continue with step 2, above, until the final point of interest is reached. 'Jote: The MRM should be used to calculate the peak discharge when there is a junction from independent subareas into the drainage system. 3.4 MODIFIED RATIONAL METHOD (FOR JUNCTION ANALYSIS) The purpose of this section is to describe the steps necessary to develop a hydrology report for a small watershed using the MRM. It is necessary to use the MRM if the watershed contains junctions of independent drainage systems. The process is based on the design manuals of the City/County of San Diego. The general process description for using this method, including an example of the application of this method, is described below. The engineer should only use the MRM for drainage areas up to approximately I square mile in size. If the watershed will significantly exceed 1 square mile then the NRCS method described in Section 4 should be used. The engineer may choose to use either the RM or the MRM for calculations for up to an approximately I-square-mile area and then transition the study to the NRCS method for additional downstream areas that exceed approximately I square mile. The transition process is described in Section 4. 3.4.1 Modified Rational Method General Process Description The general process for the MRl\1 differs from the RM only when a junction of independent drainage systems is reached. The peak Q. Tc, and I for each of the independent drainage systems at the point of the junction are calculated by the RM. The independent drainage systems are then combined using the MRM procedure described below. The peak Q, Tc, and I for each of the independent drainage systems at the point of the junction must be calculated prior to using the MRM procedure to combine the independent drainage systems, as these 3-23 San Diego County Hydrology Manual Date: June 2003 0 Section: Page: ATTACHMENT 21 3 24 of26 values will be used for the MRM calculations. After the independent drainage systems have been combined, RM calculations are continued to the next point of interest. 3.4.2 Procedure for Combining Independent Drainage Systems at a Junction Calculate the peak Q, Tc, and I for each of the independent drainage systems at the point of the junction. These values will be used for the MRM calculations. At the junction of two or more independent drainage systems, the respective peak flows are combined to obtain the maximum flow out of the junction at Tc. Based on the approximation that total runoff increases directly in proportion to time, a general equation may be written to determine the maximum Q and its corresponding Tc using the peak Q, Tc, and I for each of the independent drainage systems at the point immediately before the junction. The general equation requires that contributing Q's be numbered in order of increasing Tc. Let Q1, T1, and 11 correspond to the tributary area with the shortest Tc. Likewise, let Q2, T2, and Ii correspond to the tributary area with the next longer Tc; Q3, T3, and h correspond to the tributary area with the next longer Tc; and so on. When only two independent drainage systems are combined, leave Q3, T3, and h out of the equation. Combine the independent drainage systems using the junction equation below: Junction Equation: Ti< T2 < T3 3-24 4 I I • ATTACHMENT 21 San Diego County Hydrology Manual Date: June 2003 Section: Page: 3 25 of26 Calculate Qn, Qn, and Qr,. Select the largest Q and use the Tc associated with that Q for further calculations (see the three Notes for options). If the largest calculated Q's are equal (e.g., Oi-1 = Qn > QT3), use the shorter of the Tc's associated with that Q. This equation may be expanded for a junction of more than three independent drainage systems using the same concept. The concept is that when Q from a selected subarea ( e.g., Q2) is combined with Q from another subarea with a shorter T0 (e.g., Qi), the Q from the subarea with the sh011er Tc is reduced by the ratio of the I's (hil1); and when Q from a selected subarea (e.g., Q2) is combined with Q from another subarea with a longer Tc (e.g .• Q3), the Q from the suharea with the longer Tc is reduced by the ratio of the Tc's (T)Ti). Note #1: At a junction of two independent drainage systems that have the same Tc, the tributary flows may be added to obtain the Q~. This can be verified by using the junction equation above. Let Q3, T3, and 13 = 0. When Tr and T2 are the same, 11 and hare also the same, and T1/T2 and h/1 1 = I. T1/T2 and fi/1 1 are cancelled from the equations. At this point, QT1 = QT2 = Qi + Q2. Note #2: In the upstream part of a watershed, a conservative computation is acceptable. When the times of concentration (Tc's) are relatively close in magnitude (within 10%), use the shorter Tc for the intensity and the equation Q = L(CA)l. Note #3:. An optional method of determining the Tc is to use the equation Tc= [(L (CA)7.44 P6)/Q] 155 This equation is from Q = I(CA)I = I(CA)(7.44 Ptlfc645 ) and solving for Tc. The advantage in this option is that the Tc is consistent with the peak flow Q, and avoids inappropriate fluctuation in downstream flows in some cases. 3-25 C 0 I '' • ATTACHMENT 21 STORMTRAP® TYPICAL SPECIFICATIONS FOR "SINGLE TRAP" SYSTEM STORMTRAP INSTALLATION SPECIFICATION 1 STORMTRAP MODULES SHALL BE MQ.NUFACTUREO ACCORDING TO SHOP DRAWINGS APPROVED BY THE INSTALLING CONTRACTOR AND ENGINEER.

P-6541115 Pages This report presents the results of our geotechnical investigation on the subject property. The purpose of this study is to evaluate the nature and characteristics of the earth materials underlying the property, the engineering properties of the surficial deposits and their influence on the proposed twin home development. SITE CONDITIONS The subject property is located north of Juniper A venue, along the east side of Carlsbad Boulevard, in the city of Carlsbad. The subject property is a relatively level rectangular residential lot. The site includes a single story residence with an attached garage. Access to the rear of the site is via an alley which enters from Juniper A venue. The property is bounded along the north, south and east by developed residential lots. Vegetation includes grass, shrubs and a few trees. Drainage is generally by sheet flow to the east. PROPOSED DEVELOPMENT Concept plans for the development of the site were prepared by Transpacific Architects. It is our understanding that the project will include demolition of the existing structure and the construction of a new two (2) unit twin home structure. The structure will be constructed slightly below existing Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page6 grade. It is anticipated that excavation of approximately 1. 0 vertical feet will be necessary to achieve pad grade. SITE INVESTIGATION Two (2) exploratory borings were drilled to a maximum depth of20 feet with a tri-pod hollow-stem drill rig. Earth materials encountered were visually classified and logged by our field engineering geologist. Standard penetration tests (SPT) were performed in the hollow-stem borings. Undisturbed, representative samples of earth materials were obtained at selected intervals. Samples were obtained by driving a thin walled steel sampler into the desired strata. The samples are retained in brass rings of 2.5 inches outside diameter and 1.0 inches in height. The central portion of the sample is retained in close fitting, waterproof containers and transported to our laboratory for testing and analysis. LABORATORY TESTING Classification The field classification was verified through laboratory examination, in accordance with the Unified Soil Classification System. The final classification is shown on the enclosed Exploratory Logs. Moisture/Density The field moisture content and dry unit weight were determined for each of the undisturbed soil C 0 Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page7 samples. This information is useful in providing a gross picture of the soil consistency or variation among exploratory excavations. The dry unit weight was determined in pounds per cubic foot. The field moisture content was determined as a percentage of the dry unit weight. Both are shown on the enclosed Laboratory Tests Results and Exploratory Logs. Maximum Dry: Density and Optimum Moisture Content The maximum dry density and optimum moisture content were determined for selected samples of earth materials taken from the site. The laboratory standard tests were in accordance with ASTM D-1557-91. The results of the tests are presented in the Laboratory Test Results. Shear Test Shear tests were performed in a strain-control type direct shear machine. The rate of deformation was approximately 0.025 inches per minute. Each sample was sheared under varying confining loads in order to determine the Coulomb shear strength parameters, cohesion and angle of internal friction. Samples were tested in a saturated condition. The results are presented in the Laboratory Test Results. Sulfate Test A sulfate test was performed on a selected sample in accordance with California Test Method (CTM) 417. The results are presented in the Lab Test Results. Coast Geotechnical GEOLOGIC CONDITIONS ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page8 The subject property is located in the Coastal Plains Physiographic Province of San Diego. The property is underlain at relatively shallow depths by Pleistocene terrace deposits. The terrace deposits are underlain at depth by Eocene-age sedimentary rocks which have commonly been designated as the Santiago Formation on published geologic maps. The terrace deposits are covered by thin soil deposits and, in part, by minor fill deposits. A brief description of the earth materials encountered on the site follows. Artificial Fill (at) No evidence of significant fill deposits were observed on the site. However, minor fill deposits, up to approximately 1.0 foot, are present along the perimeter of the residence. The fill is composed of locally derived silty, fine and medium-grained sand. The rear parking area is covered by approximately 4.0 inches of gravel. Soil (Os) Approximately 8.0 inches of soil was encountered in the exploratory borings. The soil is composed of brown silty fine and medium-grained sand. The soil is generally slightly moist and loose. The contact with the underlying terrace deposits is gradational. C Coast Geotechnical Terrace Deposits (Ot) 0 ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 9 Underlying the surficial materials, poorly consolidated Pleistocene terrace deposits are present. The terrace deposits are composed of tan to reddish brown, fine and medium-grained sand and are generally moist to very moist and weathered in the upper 2.0 to 3. 0 feet. Below the weathered zone, the terrace deposits are in a medium dense to dense condition. The terrace deposits generally exhibit little or no cohesion. Regionally, the Pleistocene sands are considered flat-lying and are underlain at depth by Eocene-age sedimentary rock units. Medium-dense to dense terrace deposits are considered suitable for the support of foundations and fills. Expansive Soil Based on our experience in the area and previous laboratory testing of selected samples, the fill deposits, residual soil and Pleistocene sands reflect an expansion potential in the very low range. Groundwater No groundwater was observed to the depth explored. However, it should be noted that seepage problems can develop after completion of construction. These seepage problems most often result from drainage alterations, landscaping and over-irrigation. In the event that seepage or saturated ground does occur, it has been our experience that they are most effectively handled on an individual basis. Coast Geotechnical Tectonic Setting ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 10 The site is located within the seismically active southern California region which is generally characterized by northwest trending Quaternary-age fault zones. Several of these fault zones and fault segments are classified as active by the California Division of Mines and Geology (Alquist- Priolo Earthquake Fault Zoning Act). Based on a review of published geologic maps, no known faults transverse the site. The nearest active fault is the offshore Rose Canyon Fault Zone located approximately 4.3 miles west of the site. It should be noted that the Rose Canyon Fault is not a continuous, well-defined feature but rather a zone of right stepping en echelon faults. The complex series of faults has been referred to as the Offshore Zone of Deformation (Woodward-Clyde, 1979) and is not fully understood. Several studies suggest that the Newport-Inglewood and the Rose Canyon faults are a continuous zone of en echelon faults (Treiman, 1984 ). Further studies along the complex offshore zone of faulting may indicate a potentially greater seismic risk than current data suggests. Other faults which could affect the site include the Coronado Bank, Elsinore, San Jacinto and San Andreas Faults. The proximity of major faults to the site and site parameters are shown on the enclosed Seismic Design Parameters. Liguefaction Potential Liquefaction is a process by which a sand mass loses its shearing strength completely and flows. The temporary transformation of the material into a fluid mass is often associated with ground motion resulting from an earthquake. C 0 Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 11 Owing to the medium-dense nature of the Pleistocene terrace deposits and the anticipated depth to groundwater, the potential for seismically induced liquefaction and soil instability is considered low. CONCLUSIONS 1) The subject property is located in an area that is relatively free of potential geologic hazards such as landsliding, high groundwater tables, liquefaction and seismically induced subsidence. 2) The existing fill, soil and weathered terrace deposits encountered on the site are unsuitable for the support of proposed footings and concrete flatwork in their present condition. These surficial deposits should be removed and replaced as properly compacted fill for the support of foundations, concrete flatwork and exterior improvements. 3) The proposed development should not adversely affect the adjacent properties provided the recommendations of this report are implemented during the design and construction phases. RECOMMENDATIONS Removals/Recompaction The existing fill, soil and weathered terrace deposits in the building pad should be removed and replaced as properly compacted fill. All fill should be keyed and benched into the underlying terrace Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 12 deposits. Removals should extend a minimum of 5.0 feet beyond the building footprint. A I: I (horizontal to vertical) temporary slope should be graded along the property lines. Fill should be benched into the temporary slope. Additional recommendations will be necessary based on proposed plans and actual field conditions encountered during grading. The depth of removals are anticipated to be on the order of3.5 feet. However, a minimum of 1.5 feet of fill should underlie footings. Most of the existing earth deposits are generally suitable for reuse, provided they are cleared of all vegetation, debris and thoroughly mixed. Prior to placement of fill, the base of the removal should be observed by a representative of this firm. Additional overexcavation and recommendations may be necessary at that time. The exposed bottom should be scarified to a minimum depth of 6.0 inches, moistened as required and compacted to a minimum of 90 percent of the laboratory maximum dry density. Fill should be placed in 6.0 to 8.0 inch lifts, moistened to approximately 1.0 -2.0 percent above optimum moisture content and compacted to a minimum of 90 percent of the laboratory maximum dry density. Fill, soil and weathered terrace deposits in areas of proposed concrete flatwork and driveways should be removed and replaced as properly compacted fill. Imported fill, if necessary, should consist of non-expansive granular deposits approved by the geotechnical engineer. Temporary Slopes/Excavation Characteristics Temporary excavations, up to 5. 0 feet, should be trimmed to a gradient of 1 : 1 (horizontal to vertical) or less depending upon conditions encountered during grading. The terrace deposits exhibit little C 0 Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 13 or no cohesion and some degree of sloughing may occur along the temporary slope face. Based on the concept plans, shoring is not anticipated. Based on our experience in the area, the Pleistocene terrace deposits are easily rippable with conventional medium to heavy earth moving equipment in good working order. Foundations The following design parameters are based on footings founded into non-expansive approved compacted fill deposits or competent terrace deposits. Footings should not span cut/fill transitions. Footings for the proposed structure should be a minimum of 12 inches and 15 inches wide and founded a minimum of 12 inches and 18 inches below the lower most adjacent subgrade at the time of foundation construction for single-story and two-story structures, respectively. A 12 inch by 12 inch grade beam or footing should be placed across the garage opening. Footings should be reinforced with a minimum of four No. 4 bars, two along the top of the footing and two along the base. Footing recommendations provided herein are based upon underlying soil conditions and are not intended to be in lieu of the project structural engineer's design. For design purposes, an allowable bearing value of 1700 pounds per square foot and 2000 pounds per square foot may be used for foundations at the recommended footing depths for single and two story structures, respectively. Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 14 For footings deeper than 18 inches, the bearing value may be increased by 20 percent for each additional foot of embedment and 10 percent for each additional foot of width of footing to a maximum of 3500 pounds per square foot. The bearing value may be increased by one-third for short durations of loading, which includes the effects of wind and seismic forces. The bearing value indicated above is for the total dead and frequently applied live loads. This value may be increased by 33 percent for short durations of loading, including the effects of wind and seismic forces. Sulfate Content Based on selective testing, the soluble sulfate content is negligible. Slabs on Grade (Interior and Exterior) Slabs on grade should be a minimum of 5.0 inches thick and reinforced in both directions with No. 3 bars placed 18 inches on center in both directions. Exterior slabs on grade should be a minimum of 4.0 inches thick and reinforced with No. 3 placed 18 inches on center in both directions. The slab should be underlain by a minimum 2.0-inch coarse sand blanket (S.E. greater than 30). Where moisture sensitive floors are used, a minimum 10.0-mil Visqueen, Stego or equivalent moisture barrier should be placed over the sand blanket and covered by an additional two inches of sand (S.E. greater than 30). Utility trenches underlying the slab may be backfilled with on-site materials, compacted to a minimum of 90 percent of the laboratory maximum dry density. Slabs including 0 Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 15 exterior concrete flatwork should be reinforced as indicated above and provided with saw cuts/expansion joints, as recommended by the project structural engineer. All slabs should be cast over dense compacted subgrades. Exterior slabs should be provided with weakened plane joints at frequent intervals in accordance with the American Concrete Institute (ACI) guidelines. Our experience indicates that the use of reinforcement in slabs and foundations can reduce the potential for drying and shrinkage cracking. However, some minor cracking is considered normal and should be expected as the concrete cures. Moisture barriers can retard but not eliminate moisture vapor movement from the underlying soils up through the slab. Lateral Resistance Resistance to lateral load may be provided by friction acting at the base of foundations and by passive earth pressure. A coefficient of friction of 0.25 may be used with dead-load forces. A passive earth pressure of 200 pounds per square foot, per foot of depth of fill or terrace deposits penetrated to a maximum of 2500 pounds per square foot may be used. Retaining Walls Cantilever walls (yielding) retaining nonexpansive granular soils may be designed for an active- equivalent fluid pressure of 38 pounds per cubic foot for a level surcharge. Restrained walls (nonyielding) should be designed for an "at-rest" equivalent fluid pressure of 60 pounds per cubic foot. Wall footings should be designed in accordance with the foundation design recommendations. Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 16 All retaining walls should be provided with an adequate backdrainage system. A geocomposite blanket drain such as Miradrain 6000 or equivalent is recommended behind walls. The soil parameters assume a level nonexpansive select granular backfill compacted to a minimum of 90 percent of the laboratory maximum dry density. Dynamic (Seismic) Lateral Earth Pressures For proposed restrained walls (non-yielding), potential seismic loading should be considered. For smooth rigid walls Wood (1973) expressed the dynamic thrust in the following form: 6Pe = kb YH2 (non-yielding) where kb is ½ peak ground acceleration equal to 50 percent of the design spectral response acceleration coefficient (Sds) divided by 2.5 per C.B.C. (2007), Y is equal to the unit weight of backfill and H is equal to the height of the wall. The pressure diagram for this dynamic component can be approximated as an inverted trapezoid with stress decreasing with depth. The point of application of the dynamic thrust is at a height of 0.6 above the base of the wall. The magnitude of the resultant is : 6Pe = 20.1 H2 (non-yielding) This dynamic component should be added to the at-rest static pressure for seismic loading conditions. Coast Geotechnical ,-... '-" 0 ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 17 For cantilever walls (yielding), Seed and Whitman (1970) developed the dynamic thrust as: aPe = 3/8 kh YH2 (yielding) The pressure diagram for this dynamic component can be approximated as an inverted trapezoid with stress decreasing with depth and the resultant at a height of 0.6 above the base of the wall. The magnitude of the resultant is: aPe = 7 .5 H2 (yielding) This dynamic component should be added to the static pressure for seismic loading conditions. Settlement Characteristics Estimated total and differential settlement over a horizontal distance of 30 feet is expected to be on the order of 1.0 inch and 3/4 inch, respectively. It should also be noted that long term secondary settlement due to irrigation and loads imposed by structures is anticipated to be 1/4 inch. Seismic Considerations Although the likelihood of ground rupture on the site is remote, the property will be exposed to moderate to high levels of ground motion resulting from the release of energy should an earthquake occur along the numerous known and unknown faults in the region. The Rose Canyon Fault Zone located approximately 4.3 miles west of the property is the nearest known active fault and is considered the design earthquake for the site. Coast Geotechnical Seismic Ground Motion Design Parameters ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 18 Seismic ground motion values were determined as part of this investigation in accordance with Chapter 16, Section 1613 of the 2013 California Building Code (CBC) and ASCE 7-10 Standard using the web-based United States Geological Survey (USGS) ground motion calculator. Generated results including the Mapped (Ss, S1), Risk-Targeted Maximum Considered Earthquake (MCER) adjusted for site Class effects (SMs, SM1) and Design (Sos, S01) Spectral Acceleration Parameters as well as Site Coefficients (Fa, Fv) for short periods (0.20 second) and I-second period, Site Class, Design and Risk-Targeted Maximum Considered Earthquake (MCER) Response Spectrums, Mapped Maximum Considered Geometric Mean (MCEo) Peak Ground Acceleration adjusted for Site Class effects (PGAM) and Seismic Design Category based on Risk Category and the severity of the design earthquake ground motion at the site are summarized in the enclosed Appendix A. Site Class D Seismic Design Category D Ss: 1.161 S1: 0.445 SMs: 1.203 SMI: 0.692 SDs: 0.802 SDI: 0.461 Fa: 1.035 Fv: 1.555 C Coast Geotechnical Preliminary Pavement Design 0 ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 19 The following preliminary pavement section is recommended for proposed driveways: 4.0 inches of asphaltic concrete on 6.0 inches of select base (Class 2) on 12 inches of compacted subgrade soils or 5 .5 inches of concrete on 12 inches of compacted subgrade soils Subgrade soils should be compacted to the thickness indicated in the structural section and left in a condition to receive base materials. Class 2 base materials should have a minimum R-value of 78 and a minimum sand equivalent of 30. Subgrade soils and base materials should be compacted to a minimum of95 percent of their laboratory maximum dry density. Concrete should be reinforced with No. 3 bars placed 18 inches on center in both directions. It is suggested that concrete be underlain by a minimum of 4.0 inches of Class 2 base. The pavement section should be protected from water sources. Migration of water into subgrade deposits and base materials could result in pavement failure. Utility Trench We recommend that all utilities be bedded in clean sand (S.E. greater than 30) to at least one foot above the top of the conduit. The bedding should be moistened and tamped in place to fill all the voids around the conduit. Imported or on-site granular material compacted to at least 90 percent relative compaction may be utilized for backfill above the bedding. ,-. Coast Geotechnical ATTACHMENT 22 February 11, 2016 W.O. P-6541115 Page 20 The invert of subsurface utility excavations paralleling footings should be located above the zone of influence of these adjacent footings. This zone of influence is defined as the area below a 45 degree plane projected down from the nearest bottom edge of an adjacent footing. This can be accomplished by either deepening the footing, raising the invert elevation of the utility, or moving the utility or the footing away from one another. Drainage Specific drainage patterns should be designed by the project architect or engineer. However, in general, pad water should be directed away from foundations. Roof water should be collected and transferred to hardscape. Vegetation adjacent to foundations should be avoided. If vegetation in these areas is desired, sealed planter boxes or drought resistant plants should be considered. Other alternatives may be available, however, the intent is to reduce moisture from migrating into foundation subsoils. Irrigation should be limited to that amount necessary to sustain plant life. All drainage systems should be inspected and cleaned annually, prior to winter rains. Geotechnical Observations Structural footing excavations should be observed by a representative of this firm, prior to the placement of steel and forms. All fill should be placed while a representative of the geotechnical engineer is present to observe and test. C Coast Geotechnical Plan Review 0 ATTACHMENT 22 February 11, 2016 W.O.

All of the guidelines may not apply to a specific site and additional recommendations may be necessary during the grading phase. Site Clearin& Trees, dense vegetation, and other deleterious materials should be removed from the site. Non- organic debris or concrete may be placed in deeper fill areas under direction of the Soils engineer. Subdraina&e 1. During grading, the Geologist and Soils Engineer should evaluate the necessity of placing additional drains. 2. All subdrainage systems should be observed by the Geologist and Soils Engineer during construction and prior to covering with compacted fill. 3. Consideration should be given to having subdrains located by the project surveyors. Outlets should be located and protected. Treatment of Existin& Ground 1. All heavy vegetation, rubbish and other deleterious materials should be disposed of off site. 2. All surficial deposits including alluvium and colluvium should be removed unless otherwise indicated in the text of this report. Groundwater existing in the alluvial areas may make excavation difficult. Deeper removals than indicated in the text of the report may be necessary due to saturation during winter months. 3. Subsequent to removals, the natural ground should be processed to a depth of six inches, moistened to near optimum moisture conditions and compacted to fill standards. Fill Placement 1. Most site soil and bedrock may be reused for compacted fill; however, some special processing or handling may be required (see report). Highly organic or contaminated soil should not be used for compacted fill. 2. Material used in the compacting process should be evenly spread, moisture conditioned, processed, and compacted in thin lifts not to exceed six inches in thickness to obtain a uniformly dense layer. The fill should be placed and compacted on a horizontal plane, unless otherwise fowid acceptable by the Soils Engineer. (1) ATTACHMENT 22 3. If the moisture content or relative density varies from that acceptable to the Soils engineer, the Contractor should rework the fill until it is in accordance with the following: a) Moisture content of the fill should be at or above optimwn moisture. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or removal areas should be considered in addition to watering during fill placement, particularly in clay or dry surficial soils. b) Each six inch layer should be compacted to at least 90 percent of the maximum density in compliance with the testing method specified by the controlling governmental agency. In this case, the testing method is ASTM Test Designation D-1557-91. 4. Side-hill fills should have a minimwn equipment-width key at their toe excavated through all surficial soil and into competent material (see report) and tilted back into the hill. As the fill is elevated, it should be benched through surficial deposits and into competent bedrock or other material deemed suitable by the Soils Engineer. 5. Rock fragments less than six inches in diameter may be utilized in the fill, provided: a) They are not placed in concentrated pockets; b) There is a sufficient percentage of fine-grained material to surround the rocks; c) The distribution of the rocks is supervised by the Soils Engineer. 6. Rocks greater than six inches in diameter should be taken off site, or placed in accordance with the recommendations of the Soils Engineer in areas designated as suitable for rock disposal. 7. In clay soil large chunks or blocks are common; if in excess of six (6) inches minimwn dimension then they are considered as oversized. Sheepsfoot compactors or other suitable methods should be used to break the up blocks. 8. The Contractor should be required to obtain a minimwn relative compaction of 90 percent out to the finished slope face of fill slopes. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment. If fill slopes are built "at grade" using direct compaction methods then the slope construction should be performed so that a constant gradient is maintained throughout construction. Soil should not be "spilled" over the slope face nor should slopes be "pushed out" to obtain grades. Compaction equipment should compact each lift along the immediate top of slope. Slopes should be back rolled approximately every 4 feet vertically as the slope is built. Density tests should be taken periodically during grading on the flat surface of the fill three to five feet horizontally from the face of the slope. (2) ATTACHMENT 22 In addition, if a method other than over building and cutting back to the compacted core is to be employed, slope compaction testing during construction should include testing the outer six inches to three feet in the slope face to determine if the required compaction is being achieved. Finish grade testing of the slope should be performed after construction is complete. Each day the Contractor should receive a copy of the Soils Engineer's "Daily Field Engineering Report" which would indicate the results of field density tests that day. 9. Fill over cut slopes should be constructed in the following manner: a) All surficial soils and weathered rock materials should be removed at the cut-fill interface. b) A key at least 1 equipment width wide (see report) and tipped at least 1 foot into slope should be excavated into competent materials and observed by the Soils Engineer or his representative. c) The cut portion of the slope should be constructed prior to fill placement to evaluate if stabilization is necessary, the contractor should be responsible for any additional earthwork created by placing fill prior to cut excavation. 10. Transition lots (cut and fill) and lots above stabilization fills should be capped with a four foot thick compacted fill blanket (or as indicated in the report). 11. Cut pads should be observed by the Geologist to evaluate the need for overexcavation and replacement with fill. This may be necessary to reduce water infiltration into highly fractured bedrock or other permeable zones, and/or due to differing expansive potential of materials beneath a structure. The overexcavation should be at least three feet. Deeper overexcavation may be recommended in some cases. 12. Exploratory backhoe or dozer trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. Gradini Observation and Testini 1. Observation of the fill placement should be provided by the Soils Engineer during the progress of grading. 2. In general, density tests would be made at intervals not exceeding two feet of fill height or every 1,000 cubic yards of fill placed. This criteria will vary depending on soil conditions and the size of the fill. In any event, an adequate number of field density tests should be made to evaluate if the required compaction and moisture content is generally being obtained. 3. Density tests may be made on the surface material to receive fill, as required by the Soils Engineer. (3) ATTACHMENT 22 4. Cleanouts, processed ground to receive fill, key excavations, subdrains and rock disposal should be observed by the Soils Engineer prior to placing any fill. It will be the Contractor's responsibility to notify the Soils Engineer when such areas are ready for observation. 5. A Geologist should observe subdrain construction. 6. A Geologist should observe benching prior to and during placement of fill. Utility Trench Backfill Utility trench backfill should be placed to the following standards: 1. Ninety percent of the laboratory standard if native material is used as backfill. 2. As an alternative, clean sand may be utilized and flooded into place. No specific relative compaction would be required; however, observation, probing, and if deemed necessary, testing may be required. 3. Exterior trenches, paralleling a footing and extending below a 1 : 1 plane projected from the outside bottom edge of the footing, should be compacted to 90 percent of the laboratory standard. Sand backfill, unless it is similar to the inplace fill, should not be allowed in these trench backfill areas. Density testing along with probing should be accomplished to verify the desired results.
