This SWPPP conforms with the required elements of the Permit and with the required elements of the General Permit issued by the State of Califomia, State Water Resources Control Board (SWRCB). This SWPPP will be modified and amended to reflect any amendments to the Permits, or any changes in construction or operations that may affect the discharge of pollutants from the construction site to surface waters, groundwaters, or the municipal separate storm sewer system (MS4). The SWPPP will also be amended if it is in violation of any condition of the Permit or has nol achieved the general objective of reducing pollutants in storm water discharges. The SWPPP shall be readily available on-site for the duration of the project. 500.2 Vicinity Map The construction project vicinity map showing the project location, surface water boundaries, geographic features, construction site perimeter, and general topography, is located in Attachment A.

Coincidental to the clearing operations, erosion and other pollution prevention measures were installed under separate contract (by others). 500.3,3 Nature of Fill Material and Existing Data Describing the Soil Existing site features include existing streets to be removed and/or joined, unimproved native hillsides which have been previously cleared and an active streambed where stumps remain from past clearing operations. Some "unsuitable" areas have been identified on the project documents as areas to be excavated to approved limits and replaced. These areas are generally located near and in the streambed. Major excavation consists primarily of dense rock overlain by clayey topsoils with scattered boulders. Existing site features that, as a result of past usage, may contribute pollutants to storm water (e.g., toxic materials that are known to have been treated, stored, disposed, spilled, or leaked onto the construction site) include: K None known Embankment constmction will require sorting, stockpiling and crushing to size the material to be excavated. Crushing equipment will be utilized concurrent with excavation and embankment operations. 500.3.4 Soil Stabilization (Erosion Control) Soil stabilization, also referred to as erosion control, consists of source control measures that are designed to prevent soii particles from detaching and becoming transported in storm water runoff Soil stabilization BMPs protect the soil surface by covering and/or binding soil particles. This project will incorporate minimum temporary soil stabilization requirements, temporary soil stabilization measures required by the contract documents, and other measures selected by the 500-3 storm Water Pollution Prevention Plan (SWPPP) RANCHO SANTA FE ROAD NORTH, PHASE 2 Contract No. CONTRACT NO. 3907 CMWD PROJECT NOS. 3887 & 3923 contractor. This project will implement the following practices for effective temporary and final soil stabilization during construction: 1) Preserve existing vegetation where required and when feasible. 2) Apply temporary soil stabilization (erosion control) to remaining active and non-active areas as required by the Construction Site BMPs Manual and the Special Provisions. Reapply as necessary to maintain effectiveness. 3) Implement temporary soil stabilization measures at regular intervals throughout the defined rainy season to achieve and maintain the contract's disturbed soil area requirements. When the project's Special Provisions require it, temporary soil stabilization will be implemented 20 days prior to the defined rainy season. 4) Stabilize non-active areas within 14 days of cessation of construction activities. 5) Control erosion in concentrated flow paths by applying erosion control blankets, check dams, erosion control seeding, and lining swales as required in the special provisions. 6) Apply seed to areas deemed substantially complete by the RE during the defined rainy season. 7) At completion of construction, apply permanent erosion control to all remaining disturbed soil areas as required in the special provisions. Sufficient soil stabilization materials will be maintained on-site to allow implementation in conformance with Caltrans requirements and described in this SWPPP. This includes implementation requirements for active and non-active areas that require deployment before the onset of rain. Implementation and locations of temporary soil stabilization BMPs are shown on the Water Pollution Control Drawings (WPCDs) in Attachment B and/or described in this section.

Examples include the procedures used by Riverside County, Los Angeles County, Orange County, City of San Francisco, City of Oakland, Denver Urban Drainage District, and references from APWA and ASCE. County Flood Control has evaluated precipitation and stream flow recorded data since the Flood Control District was established in 1968. Extensive analysis ofthe methodology for the rational and unit hydrograph procedures has also been accomplished. This includes analysis of the runoff process and comparison of the two methods. This experience provides a basis for the development of this report. in 1969, Design and Construction of Sanitary and Storm Sewers and the 1992 Design and Constmction of Urban Storm water Management Systems were published by the American Society of Civil Engineers and the Water Environmental Federation.

Ofthe 28 Land Uses, 15 have densities of one or more dwelling units per acre and are listed in Table III with respect to their Land Use Element Number. The effective percent impervious is based on discussions with the Planning Department, evaluation of typical land use pattems, amount of roofs, driveways, parking surfaces, etc. that are direct/indirect connection to the storm system and the Soil Conservation Service (SCS) criteria in the County Hydrology Manual. Attachment E Computational Sheet for Determining Run-on Discharges INSTRUCTIONS M Item A. The runoff coefficient represents the percent of water, which will run off the ground surface during the storm. Values of the coefficient, "C*', can be determined from Figure 8I9.2A, "Runoff Coefficients for Undeveloped Areas", and Table 819.2B, "Runoff Coefficients for Developed Areas", from Caltrans, ' Highway Design Manual, Fifth Edition. • Refer to the Caltrans Highway Design Manual, Topic 819 - Estimating Design Discharge, for a more detailed explanation on calculating weighted runoff coefficients for areas containing varying amounts of different cover. • Item B. Rainfall intensity, in millimeters per hour, is the average rainfall intensity for the selected frequency. Refer to the County Flood Control, or U. S. Army Corps of Engineers manuals for rainfall intensity values. • Item C. Drainage area in square kilometers includes impervious and pervious areas and surfaces covered by buildings. • SWPPP preparer shall provide calculations for offsite run-on if flow quantities ^ are not available via the project design documents (Drainage Report, Hydrology ^ Report, etc.) • The rational method should not be used for drainage areas greater than 1.3 km^ ^ (130 ha).

To obtain authorization for proposed storm water discharges to surface waters, pursuant to this General Permit, the landowner (discharger) must submit a Notice of Intent (NOI) with a vicinity map and the appropriate fee to the SWRCB prior to commencement of constmction activities. In addition, coverage under this General Pennit shall not occur until the apphcant develops a Storm Water Pollution Prevention Plan (SWPPP) in accordance with the requirements of Section A of this pennit for the project. For proposed constmction activity conducted on easements or on nearby property by agreement or permission, or by an owner or lessee of a mineral estate (oil, gas, geothennal, aggregate, precious metals, and/or industrial minerals) entitled to conduct the activities, the entity responsible for the constmction activity must submit the NOI and filing fee and shall be responsible for development of the SWPPP. 5. If an mdividual NPDES Permit is issued to a discharger otherwise subject to this General Permit or if an altemative General Pennit is subsequently adopted which covers stonn water discharges regulated by this General Pennit, the apphcability of this General Pennit to such discharges is automatically tenninated on the effective date ofthe individual pennit or the date of approval for coverage imder the subsequent General Permit. 6. This action to adopt an NPDES pennit is exempt fix)m the provisions of the California Environmental Quality Act (Pubhc Resources Code Section 21100, et seq,) in accordance with section 13389 ofthe CaHfomia Water Code. 7. The SWRCB adopted the Califomia Ocean Plan, and the RWQCBs have adopted and the SWRCB has approved Water Quality Control Plans (Basin Plans). Dischargers regulated by this General Permit must comply with the water quality standards in these Basin Plans and subsequent amendments thereto. 8. The SWRCB finds storm water discharges associated with constmction activity to be a potential significant sources of pollutants. Furthennore, the SWRCB finds that stonn water discharges associated with constmction activities have the reasonable potential to cause or contribute to an excursion above water quality standards for sediment in the water bodies listed in Attachment 3 to this pennit. 9. It is not feasible at this time to establish numeric effluent hmitations for pollutants in storm water discharges from constmction activities. Instead, the provisions of this General Permit require implementation of Best Management Practices (BMPs) to control and abate the discharge of pollutants in storm water discharges. 10. Discharges of non-stonn water may be necessary for the completion of certain constmction projects. Such discharges include, but are not limited to: irrigation of vegetative erosion control measures, pipe flushing and testing, street cleaning, and ^ dewatering. Such discharges are autiiorized by this General Permit as long as they (a) do ^1 comply with Section A.9 of this General Permh. (b) do not cause or contribute to violation of any water quality standard, (c) do not violate any other provision of this General Permit, (d) do not require a non-storm water pennit as issued by some RWQCBs, '^""^ (®) not prohibited by a Basin Plan. If a non-stonn water discharge is subject to a separate peimit adopted by a RWQCB, die discharge must additionally be authorized by the RWQCB pennit. 11. Following adoption of tiiis General Pennit, tiie RWQCBs shall enforce tiie provisions herein including the monitoring and reporting requirements. 12. Following public notice in accordance with State and Federal laws and regulations, the SWRCB in a pubhc meeting on June 8, 1998, heard and considered all comments. The SWRCB has prepared written responses to all significant comments. 13. This Order is an NPDES permit in compliance with section 402 ofthe Clean Water Act (CWA) and shall take effect upon adoption by tiie SWRCB provided the Regional Administrator of tiie USEPA has no objection. If tiie USEPA Regional Administrator objects to its issuance, the General Permit shall not become effective until such objection is withdrawn. 14. This General Permit does not authorize discharges of fill or dredged material regulated by tiie U.S. Amay Corps of Engineers under CWA section 404 and does not constitute a waiver of water quality certification under CWA section 401. IT IS HEREBY ORDERED tiiat all dischargers who file an NOI indicating tiieir intention to be regulated under tiie provisions of tiiis General Permit shall comply witii tiie following: A. DISCHARGE PROHIBITIONS: 1. Autiiorization pursuant to this General Pennit does not constitute an exemption to applicable discharge prohibitions prescribed in Basin Plans, as implemented by tiie nine RWQCBs. 2. Discharges of material otiier tiian storm water which are not otherwise autiiorized by an NPDES pennit to a separate storm sewer system (MS4) or waters ofthe nation are prohibited, except as allowed in Special Provisions for Constmction Activity, C.3. 3. Stonn water discharges shall not cause or tiu-eaten to cause pollution, contamination, or nuisance. 4.

Erosion Control Erosion control, also refened to as "soil stabilization" is tiie most effective way to retain soil and sediment on tiie constraction site. The most efficient way to address erosion control is to preserve existing vegetation where feasible, to limit disttirbance, and to stabilize and revegetate disttu-bed areas as soon as possible after grading or consttiiction Particular attention must be paid to large mass-graded sites where tiie potential for soil exposure to tiie erosive effects of rainfall and wind is great. Mass graded consttiiction sites may be exposed for several yeais while tiie project is being built out. Thus, tiiere is potential for significant sediment discharge from tiie site to surface waters. At a minimum, tiie discharger/operator must implement an effective combination of erosion and sediment contt-ol on all disttirbed areas during the rainy season These disttiri>ed areas include rough graded roadways, slopes, and building pads. Until pennanent vegetation is estabhshed, soil cover is tiie most cost-effective and expeditious mrthod to protect soil particles from detachment and transport by rainfall. Temporary soil stabilization can be tiie single-most important factor in reducing erosion at constraction sites. The discharger shall consider measures such as: covering witii mulch temporary seedmg, soil stabilizers, binders, fiber rolls or blankets, temporary vegetation' permanent seeding, and a variety of other measures. 4 12 The SWPPP shall include a description of tiie erosion conttol practices, including a time schedule, to be unplemented during constraction to mmimize erosion on disttirbed areas of a consttuctton site. The discharger must consider tiie fiill range of erosion conttol BMPs. The discharger must consider any additional site-specific and seasonal conditions when selecttng and unplementing appropriate BMPs. The above listed erosion conlrol measures are examples of what should be considered and are not exclusive of new or mnovattve approaches cunently available or being developed. a. The SWPPP shall include: (1) An outline of tiie areas of vegetative soil cover or native vegeution onsite which will remam undisttirbed during tiie consttiiction project. (2) An outlme of all areas of soil disttirbance includmg cut or fill areas which wtil be stabilized during tiie rainy season by temporary or pennanent erosion contt-ol measures, such as seedmg. mulch, or blankets, etc. (3) An outHne of tiie areas of soil disttirbance, cut, or fiH which will be left exposed during any part of tiie rainy season, representing areas of potential soil erosion where sediment conttol BMPs are required to be used during constraction. measures. b. c. (4) A proposed schedule for tiie implementation of erosion conttol The S WPPP shall include a description of tiie BMPs and control practices to be used for botii temporary and pennanent erosion contt-ol measures. The SWPPP shall include a description of tiie BMPs to reduce wind erosion at all times, witii particular attention paid to stock-piled materials. 7. Stabilization (1) All disttirbed areas of tiie consttiiction site must be stabilized. Final stabihzatton for tiie puiposes of submitting a NOT is satisfied when: -All soil disttirbing activities are completed AND EITHER OF THE TWO FOLLOWING CRITERIA ARE MET: -A unifomi vegetative cover witii 70 percent coverage has been established OR: -equivalent stabilization measures have been employed These measures include tiie use of such BMPs as blankets, reinforced 13 channel liners, soil cement, fiber mattices, geotextiles, or otiier •"^^ erosion resistant soil coverings or treatments. (2) Where background native vegetation covers less tiian 100 percent of tiie surface, such as in arid areas, tiie 70 percent coverage criteria is adjusted as follows: If tiie native vegetation covers 50 percent ofthe ground surface, 70 percent of 50 percent (.70 X .50=.35) would require 35 percent total uniform surface coverage, 8. Sediment Control The SWPPP shall include a description or illusttation of BMPs which will be implemented to prevent a net increase of sedunent load in storni water discharge relative to preconsttiiction levels. Sediment conttol BMPs are required at appropriate locations along tiie site perimeter and at all operational intemal mlets to tiie storm drain system at all times during tiie rainy season. Sediment conttol practices may include filtration devices and barriers (such as fiber rolls, sih fence, stt-aw bale barriers, and gravel inlet filters) and/or setthng devices (such as sediment ttaps or basms). Effective filttation devices, baniers, and settlmg devices shall be selected, installed and mamtamed properly. A proposed schedule for deployment of sediment control BMPs shall be included m tiie SWPPP. These are tiie most basic measures to prevent sediment fix>m leaving tiie project ; site and movmg into receiving waters. Limited exemptions may be autiiorized by ttie ^ J RWQCB when work on active areas precludes tiie use of sediment conttol BMPs temporarily. Under ttiese conditions, tiie SWPPP must describe a plan to estabHsh perimeter controls prior to the onset of rain. During tiie nonrainy season, the discharger is responsible for ensuring tiiat adequate sediment conttol materials are available to contt-ol sediment discharges at tiie downgrade penmeter and operational inlets in tiie event of a predicted storni. The discharger shall consider a fitil range of sediment contt^ols. in addition to tiie contt-ols hsted above, such as sttaw bale dikes, earth dikes, bmsh baniers, drainage swales, check dams, subsurface drain, sandbag dikes, fiber rolls, or ottier conttols. At a minimum, tiie discharger/operator must implement an effective combination of erosion and sediment contt-ol on all disturbed areas during the rainy season. Ifthe discharger chooses to rely on sediment basins for tt-eatinent puiposes. sediment basins shall, at a mimmum, be designed and maintained as follows: Option 1: Pursuant to local ordinance for sediment basin design and maintenance. provided tiiat ttie design efficiency is as protective or more protective of water quality than Option 3. ) OR 9 14 Option 2: Sedunent basin(s), as measured from tiie bottom of tiie basin to the principal outlet, shall have at least a capacity equivalent to 3,600 cubic feet of storage per acre draining into tiie sediment basin. The lengtii of tiie basm shall be more tiian twice tiie widtii ofthe basm. The lengtii is detemuned by measuring tiie distance between tiie inlet and tiie outlet; and the deptii must not be less than three feet nor greater tiian five feet for safety reasons and for maximum efficiency. OR Option 3: Sedunent basin(s) shall be designed using ttie standard equation: As=I.2Q/Vs Where: As is tiie mmimum surface area for ttapping soil particles of a certam size; Vs is tiie settlmg velocity of tiie design particle size chosen; and Q=C x I x A where Q is tiie discharge rate measured in cubic feet per second; C is tiie runoff coefficient; I is tiie precipitation intensity for tiie 10-year. 6-hour rain event and A is tiie area draining into tiie sediment basin m acres. The design particle size shall be tiie smallest soil grain size I detennined by wet sieve analysis, or tiie fme silt sized (0.01mm) particle, ^Jj and tiie Vs used shall be 100 percent of tiie calculated settling velocity. The lengtii is determined by measuring tiie distance between the inlet and tiie outiet; tiie lengtii shall be more ttian twice tiie dimension as ttie width; ttie deptti shall not be less ttian ttiree feet nor greater than five feet for safety reasons and for maximum efficiency (two feet of storage, two feet of capacity). The basin(s) shall be located on ttie site where it can be maintained on a year-round basis and shall be maintained on a schedule to retain ttie two feet of capacity; OR Option 4: The use of an equivalent surface area design or equation, provided tiiat the design efficiency is as protective or more protective of water qualitv tiian Option 3. 1 J A sedunent basin shall have a means for dewatering witiim 7-calendar days following a stonn event Sediment basins may be fenced if safety (worker or pubhc) is a concem. The outflow fiom a sediment basm ttiat discharges into a nattiral drainage shall be ^ provided witii outiet protection to prevent erosion and scour of tiie embankment and ^ cnaimel. 15 The discharger must consider any additional site-specific and seasonal conditions when selecttng and designing sedimem contt-ol BMPs. The above listed sediment control measures are examples of what should be considered and are not exclusive of new or innovative approaches cunently available or being developed. The SWPPP shall include a description of tiie BMPs to reduce tiie ttacking of sediment onto public or pnvate roads at all times. These pubhc and private roads shall be mspected and cleaned as necessary. Road cleaning BMPs shall be discussed in tiie SWPPP and will not rely on tiie washing of accumulated sediment or silt into tiie storni drain system. 9. Non-Storm Water Management Describe all non-stonn water discharges to receivmg waters tiiat are proposed for tiie constt-uctton project. Non-storai water discharges should be ehmmated or reduced to tiie extent feasible, hiclude tiie locations of such discharges and descriptions of all BMPs designed for ttie contt-ol of pollutants in such discharges. Onetime discharges shall be momtored during tiie time tiiat such discharges are occuning. A qualified person should be assigned tiie responsibility for ensuring tiiat no materials ottier ttian storni water are discharged m quantities which will have an adverse effect on receivmg waters or stonn dram systems (consistent witti BAT/BCT), and ttie name and contact number of ttiat person should be included in tiie SWPPP document. Discharging sedim water which wiU cause or contribute to an exceedance ofthe apphcable RWQCB's Basm Plan from a dewatering site or sediment basin into any receiving water or storni drain witiiout filttation or equivalent treattnent is prohibited. ^0. Post-Constmction Storm Water Manaqement Tlie SWPPP shall include descriptions of tiie BMPs to reduce pollutants in stomi water discharges after all consttiiction phases have been completed at tiie site (Post- Consmictton BMPs). Post-Constraction BMPs include tiie minimization of land disttirbance. ttie mmimization of impervious surfaces, treattnent of storni water mnoff rsurilTo th^''? biofilter BMPs. use of efficient inigation systems, H ' "^T '^"""^^^^ " '^^^ appropriately designed and consttucted energy dissipation devices. These must be consistent witii all local post-consttuctton storni water managemem requirements, policies, and guidelines The discharger must consider site-specific and seasonal conditions when designing tiie ^m^L^J^^i K maintenance of conttol practices after constt^^^tion is completed shall be addressed, including short-and long-temi fimding sources and tiie 16 11. Maintenance. Inspection, and Repair The SWTPP shall mclude a discussion of the program to inspect and mamtain all BMPs as identified in tiie site plan or other nanative documents tiu-oughout the entire duration of tiie project. A quahfied person will be assigned tiie responsibility to conduct inspections. The name and telephone number of that person shall be listed in the SWPPP document.

The project footprint lies within Uie northwestem portion of the Rancho Santa Fe United States Geological Survey 7.5 minute quadrangle; sections 1, 6,19,20,29. 30, 31, 32; Townships 12 and 13 South; Range 3 and 4 West. Road realignment and sewer pipeline. The proposed widening and realignment project is part ofthe City of Carlsbad's General Plan to upgrade Rancho Santa Fe Road to a Prime Artenal Roadway Designation. A Prime Arterial Roadway has a 126-foot nght-of-way containing six travel lanes, a bike lane, an 18 foot raised median, sidewalks, curb, and gutter. The northeriy approach for the new bridge(s) would be approximately 2,200 feet long and include the reconstruction of the La Costa Meadows Drive/Rancho Santa Fe Road intersection, and the reconsanction of approximately 300 feet of La Costa Meadows Drive east of the intersection. The realigned Rancho Santa Fe Road would be constructed to the full width on the east side ofthe median, with sidewalks, curb and gutter, and street lights from the bridge to north of Melrose Drive. The Melrose Drive/Rancho Santa Fe Road intersection would be moved approximately 400 feet to the north ofthe present intersection. Melrose Drive would be realigned from the Comita Drive/Melrose Drive intersection northwest to the realigned Melrose Drive/Rancho Santa Fe Road intersection. Comita Drive would be extended to connect with the realigned Melrose Drive. A 24-inch sewer pipeline would also be installed by the Vallecitos Water Attachment 1 File No. OOC-045 Federal Agency/Permit: Other Required Regulatory Approvals: Califomia Environmental Quality Act (CEQA) Compliance: Receiving Water: District during construction of the bridge. The pipeline would be within the limits of temporary disturbance associated with the bridge and would not result in any additional impacts. The pipeline will be encased with concrete and riprap, with a slope of 1.5:1. will be placed around the pipe. The pipeline, concrete, and riprap will be placed below grade with a minimum of 1 foot of cover over the top. U.S. Army Corps of Engineers Nationwide Permit 14, 18, and 33 California Department of Fish and Game Streambed Alteration Agreement In 1992, the City of Carisbad approved the prehminary alignment for the Rancho Santa Fe Road realignment and Mass Grading Project; the EIR for this project was certified by the City of Carlsbad on April 3, 1992. An addendum to the final EIR was prepared in March 2000 to address the final alignment of Rancho Santa Fe Road. San Marcos Creek, unnamed ephemeral drainages In^acted Waters of the United States: Dredge Volume: Related Projects Inqjiemented/to be Implemented by the Applicant(s): Compensatory Mitigation: Best Management Practices: ^^^^^ The proposed project will permanendy impact 0.42 acre of southem willow scmb, 0.27 acre of disturbed wetlands, and 0.24 acre of unvegetated ephemeral waters of the U.S. Temporary impacts include 0.97 acre of southem willow scmb. 1,227 cubic yards. The City of Carlsbad has implemented two projects in the past five years that have resulted in temporary impacts to San Marcos Creek. The first project consisted of emergency access to repair a dip section ofthe Gibralter Street bridge. The second project replaced and/or repaired pedestrian and golf cart bridges at La Costa. T&mpor&ry impacts for both of these projects are estimated at 0.1 to 0.3 acre. The proposed mitigation program will include a total of 2.2 acres of offsite creation and 1.4 acres of offsite enhancement of jurisdictional southem willow scmb and freshwater marsh. The proposed mitigation area is located immediately east ofthe project area within University Commons along San Marcos Creek. The mitigation area will be preserved as an element of the Fieldstone HCP. In addition, 0.54 acre of jurisdictional southem willow scmb will be restored onsite within the area of impact along San Marcos Creek. All storm drain inlets shall have storm drain inlet filters (e.g.. Fossil filters or their equivalent) to treat urban runoff. Maintenance of these filters shall be conducted per the manufacturers specifications by the City of Carisbad.

Rancho Santa Fe Road North Is shown on the City of Carlsbad General Plan Circulation Element as a Prime Arterial roadway. The project extends from La Costa Avenue northerly to Melrose Drive a distance of approximately 2.25 miles. The project will grade the full road right-of- way of 126 feet and construct four of the ultimate 6 travel lanes. The adjacent landowners will construct the remaining two travel lanes, parkway and median improvements as their property develops. It is the Planning Director's determination that the project is consistent with the City's Hillside Development Ordinance, Chapter 21.95 of the Carlsbad Municipal Code and therefore approves this request based on the following: Findings: Undevelopable areas of the project, pursuant to Section 21.53.230(b) of the Carlsbad Municipal Code, have been properly identified on the constraints map. The project complies with the purpose and intent provisions of Section 21.95.010 of the Carlsbad Municipal Code in that proposed grading has been designed to relate to the slope of the land, the quantity of grading has been minimized and is 7,687 cubic yards per acre which is within the acceptable range listed in the Hillside Development Regulations, and a number of the proposed slopes will be an interim condition that will be modified when the adjacent properties are developed resulting in a lowering of the slope height In several locations. The project complies with Section 21.95.120 of the Carlsbad Municipal Code, and Section 21.95.140 if a modification to the development and design standards is approved in that hillside areas where a circulation element roadway must be located provided the proposed alignment is environmentally preferred and comply with all other city standards are excluded from the hillside development and design standards of Section 21.95.120. Rancho Santa Fe Road is designated as a prime arterial in the circulation element of the general plan and the proposed alignment has been determined to be environmentally preferred in EIR 91-01 for the Rancho Santa Fe Road Realignment and Mass Grading Project certified by the City Council 1635 Faraday Avenue • Carlsbad. CA 92008-7314 • (760) 602-4600 • FAX (760) 602-8559 • www.ci.carlsbad.ca.us ^ J I 1 J HDP 01-11 - RANCHO SANTA FE ROAD WIDENING November 30, 2001 Page 2 on June 2, 1992 and the Addendum dated March 2000. The project design results in grading quantities in the acceptable range. Were the exclusion provisions of Section 21.95.130 of the Hillside Development Regulations not applicable to the project proposed slopes which are not contour graded in addition to slopes over the maximum slope height of forty feet also qualify for a modification to the development and design standards pursuant to Section 21.95.140 (1) in that the proposed design will result in significantly more undisturbed area than requiring additional contour grading adjacent to Habitat Conservation Plan Open Space areas as this would extend slope heights and impact the preserve area and the existing native habitat. 4. The project design substantially conforms to the hillside development guidelines manual in that contour grading will occur where it will not create additional environmental impacts, runoff control will be accomplished as required by the manual through the construction of onsite catchment basins and energy dissipators, and landscaping will be installed to reduce erosion potential. The remaining design guidelines illustrated in the manual are directed at the construction and placement of structures, which are not included in this project. 5. The Planning Director has determined that: a. EIR 91-1 was certified on June 2"", 1992 in connection with the Rancho Santa Fe Road Realignment and Mass Grading project. An Addendum to the Final EIR for the project was prepared and is dated March 2000. The Hillside Development Permit, HDP 01-11 approves the proposed grading design as beirig in conformance with the Hillside Development Ordinance and the environmental impacts of the proposed project were analyzed in EIR 91-1 and the March 2000 Addendum; b. The project has no new significant environmental effect not analyzed as significant in the prior EIR 91-1 or the March 2000 Addendum; c. None of the circumstances requiring a Subsequent EIR or a Supplemental EIR under CEQA Guidelines Sections 15162 or 15163 exist. Conditions: 1. Approval is granted for HDP 01-11, as shown on Exhibit(s) "A" through "W", dated November 30, 2001, incorporated by reference and on file in the Planning Department. Development shall occur substantially as shown on the approved exhibit(s). Any proposed grading and/or development substantially different from this approval as determined by the Planning Director, shall require an amendment to this Hillside Development Permit. 2. The Developer shall implement, or cause the implementation of, the Rancho Santa Fe Road Realignment and Mass Grading Project Final Environmental Impact Report Project Mitigation Monitoring and Reporting Program as listed in City Council Resolution No. 92-152.

Work out the sequencing and timetable for the start and completion of each item such as site clearing and grubbing, grading, excavation, paving, pouring foundations, installing utilities, etc., to minimize the active construction area during the rainy season. Schedule major grading operations for the non-rainy season v>/hen practical. Stabilize non-active areas as soon as practical. Monitor the weather forecast for rainfall. When rainfall is predicted, adjust the construction schedule to allow the implementation of soil stabilization and sediment controls and sediment treatment controls on all disturbed areas prior to the onset of rain. Be prepared year-roimd to deploy soil stabilization and sediment control and sediment treatment control practices as required by Section 2 of this Manual. Erosion may be caused during dry seasons by unseasonal rainfall, wind and vehicle tracking. Keep the site stabilized year-round, and retain and maintain rainy season sediment trapping devices in operational condition. Sequence trenching activities so that most open portions are closed before new trenching begins. Incorporate staged seeding and re-vegetation of graded slopes as work progresses. Consider scheduling when establishing permanent vegetation (appropriate planting time for specified vegetation). Apply permanent erosion control to areas deemed substantially complete during the project's defined seeding window.

Soil binders are materials applied to the soil surface to temporarily prevent water-induced erosion of exposed soils on construction sites. Soil binders typically also provide dust, wind and soil stabiHzation (erosion control) benefits. This is one of five temporary soil stabilization altematives to consider. Appropriate Soil binders are applied to disturbed areas requiring short-term temporary Applications protection. Because soil binders can often be incorporated into the work, they may be a good choice for areas where grading activities will soon resume. Limitations • Soil binders are temporary in nature and may need reapplication. • Soil binders require a minimum curing time until fiiUy effective, as prescribed by the manufacturer, wiiich may be 24 hours or longer. • Soil binders will generally experience spot failures during heavy rainfall events. If runoff penetrates the soil at tiie top of a slope treated v«th a soil binder, it is likely that the runoff will imdercut the stabilized soil layer and discharge at a point further down slope. • Soil binders do not hold up to pedestrian or vehicular traffic across treated areas. • Soil binders may not penetrate soil surfaces made up primarily of silt and clay, particularly when compacted. • Some soil binders may not perform well with low relative humidity. Under rainy conditions, some agents may become slippery or leach out of the soil. 4» Caltrans Stomi Water Quality Handbooks Construction Sito Best Management Practices Manual November 2000 Soil Binders SS-6 1 of 5 SS-5 Soil Binders May not cure if low temperatures occur within 24 hours of application. Standards and General Considerations Specifications • Regional soil types will dictate appropriate soil binders to be used. • A soil binder must be environmentally benign (non-toxic to plant and animal life), easy to apply, easy to maintain, economical, and shall not stain paved or painted surfaces. • Some soil binders are compatible with existing vegetation. • Performance of soil binders depends on temperature, hiunidity, and traffic across treated areas. • Avoid over-spray onto the traveled way, sidewalks, lined drainage channels, and existing vegetation. Selecting a Soil Binder Properties of common soil binders used for erosion control are provided on Table 1. Use Table 1 to select an appropriate soil binder. Factors to consider when selectiag a soil binder include the following: ^j?] • Suitability to situation - Consider where the soil binder will be applied; if it needs a high resistance to leaching or abrasion, and wliether it needs to be compatible with any existing vegetation. Determine the length of time soil stabilization will be needed, and ifthe soil binder will be placed in an area where it will degrade rapidly. In general, slope steepness is not a discriminating factor for the listed soil binders. The soil binders in Table 1 may also be used for dust control using the provided dust control appUcation rates. The dust control appUcation rates will not be adequate to provide protection from water-induced erosion. • Soil types and surface materials - Fines and moisture content are key properties of surface materials. Consider a soil binder's ability to penetrate, likelihood of leaching, and ability to form a surface crust on the surface materials. • Frequency of appHcation - The frequency of appHcation can be affected by subgrade conditions, surface type, traffic volumes, climate, and maintenance schedule. Frequent applications could lead to high costs. Application fi^quency may be minimized if the soil binder has good penetration, low evaporation, and good longevity. Consider also that frequent application will require frequent equipment clean-up.

Application Procedures • Apply loose straw at a minimirai rate of 3,570 kg/ha (4,000 lb./acre), or as indicated in the project's special provisions, either by machine or by hand distribution. • The straw mulch must be evenly distributed on the soil surface. • Anchor the mulch in place by using a tackifier or by "punching" it into the soil mechanicaUy. • A tackifier acts to glue the straw fibers together and to the soil surface. The tackifier shaU be selected based on longevity and ability to hold the fibers ia place. • A tackifier is typically applied at a rate of 140 kg/ha (125 Ib/ac). In windy conditions, the rates are typically 200 kg/ha. • Methods for holding the straw mulch in place depend upon the slope steepness, accessibility, soil conditions and longevity.

The foUowing types of temporary stream crossings shall be considered: • Culverts - Used on perennial and intermittent streams. • Fords - Appropriate during the dry season in arid areas. Used on dry washes and ephemeral streams. Avoid use on perennial streams. • Bridges - Appropriate for streams with high flow velocities, steep gradients and/or where temporary restrictions in the channel are not allowed. Design and instaUation requires knowledge of stream flows and soU strength. Designs shaU be prepared under dfrection of, and approved by, a registered civU and/or stmctural engineer. Both hydraulic and constmction loading requirements shaU be considered with the foUowing: • Comply with the requirements for culvert and bridge crossings, as contained in the Caltrans Highway Design Manual, particularly if the temporary stream crossing wiU remain tiirough the rainy season. • Provide stabiUty in the crossing and adjacent areas to withstand the design flow. The design flow and safety factor shaU be selected based on careful evaluation of the risks due to over topping, flow backups, or washout. • InstaU sediment traps immediately downstream of crossmgs to capture sediments. See BMP SC-3, "Sediment Trap". • Avoid oU or other potentiaUy hazardous waste materials for surface treatment.
