AGENDA OF: June 3, 2009 Application complete date: April 10, 2009 Project Planner: Pam Drew Project Engineer: Eva Plajzer SUBJECT: CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING - Request for the adoption of a Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program and the approval of a Coastal Development Permit, Hillside Development Permit, Special Use Permit, and Habitat Management Plan Permit to widen a 4,600-foot (0.87 mile) length of El Camino Real between Tamarack Avenue and Chestnut Avenue in the Mello II Segment of the Local Coastal Program and within Local Facilities Management Zone 1 and 2. I.RECOMMENDATION That the Planning Commission ADOPT Planning Commission Resolution No. 6560 ADOPTING a Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program, and ADOPT Planning Commission Resolution Nos. 6561, 6562, 6563, 6564, APPROVING Coastal Development Permit (CDP 07-22), Hillside Development Permit (HDP 07-02), Special Use Permit (SUP 07-04), and Habitat Management Plan Permit (HMP 07-08) based on the findings and subject to the conditions contained therein. II.INTRODUCTION The City of Carlsbad Engineering Department has submitted a capital improvement project to widen and improve an approximately 4,600-foot or 0.87 mile length of El Camino Real from Tamarack Avenue north to Chestnut Avenue. El Camino Real is a major north/south roadway serving as a vital parallel circulation element to Interstate 5 (1-5). The project proposes to widen this section of El Camino Real to full prime arterial standards. This section of roadway, from Tamarack Avenue to Chestnut Avenue, is one of the few remaining sections of El Camino Real that has not been widened to its full width of 6 travel lanes with 3 northbound and 3 southbound lanes. The proposed 116- to 126-foot wide roadway improvement would include storm water treatment control boxes, sidewalks, bike lanes, and three traffic lanes on both sides of a landscaped median island. The project is subject to a Coastal Development Permit (CDP) since the southern portion of the project is in the Coastal Zone (2,988 linear feet are within the Coastal Zone boundary and 1,612 linear feet are outside the Coastal Zone boundary). A Hillside Development Permit (HDP) is also required due to the existing steep slopes on the west side of El Camino Real that exceed a height of fifteen feet. A Special Use Permit (SUP) is also required because the project falls within Area 2 of the El Camino Real Corridor Development Standards. The standards affect development on both public and private property, including on land within the public right-of-way. Primarily, the CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 Page 2 project is subject to the grading and landscaping provisions of the standards. Because the project will have impacts to sensitive habitat due to the installation of storm drain inlet boxes and associated energy dissipaters on the east side of El Camino Real, a Habitat Management Plan Permit (HMP) will also be required. III. PROJECT DESCRIPTION AND BACKGROUND The project is located in the northeastern part of the City as shown on the attached location map. Residential development surrounds the project site on both sides of El Camino Real. The east side has a bike lane, sidewalk, above grade utilities, and a drainage basin. Most of this area on the east side is open space with a mix of native and non-native grasses and low shrubs. The northern portion of the east side of the project is a vertically cut bank. Approximately 2,988 linear feet of El Camino Real (southern end) is within the coastal zone and approximately 1,612 linear feet (northern end) is not in the coastal zone. El Camino Real is classified as a Prime Arterial in the City's Circulation Element. Currently it is a four-lane roadway between Chestnut Avenue and Tamarack Avenue. The proposal is to widen this segment to its full width of 6 travel lanes with 3 northbound and 3 southbound lanes. The Traffic Analysis Report prepared by Linscott Law and Greenspan Engineers, dated April 20, 2006 (LLG 2006), states the traffic forecast analysis shows that in 2030 the El Camino Real and Tamarack Avenue intersection would result in a level of service (LOS) F during the AM and PM peak hours without improvements. Intersection Improvements at El Camino Real/Tamarack Avenue The project includes an additional northbound and southbound through lane on El Camino Real, and an additional northbound left-turn lane on El Camino Real at the intersection with Tamarack Avenue. With these improvements in place, future 2030 operating conditions would result in LOS D or better in the AM peak hour and LOS C in the PM peak hour, according to the Traffic Analysis Report (LLG 2006). Accommodating the additional northbound and southbound lanes, just north of the intersection, would consist primarily of re-striping the existing roadway, as sufficient width exists within the current roadway geometry. Associated signal modifications to accommodate the new lane configuration would also be provided. Intersection Improvements at El Camino Real/Chestnut Avenue At the El Camino Real/Chestnut Avenue intersection, the project would result in the removal of the existing free right turn islands located at the northwest and southwest corners of the intersection and replace these with standard curb returns, pedestrian ramps, and associated signal modifications to accommodate the road widening improvements. These intersection improvements must satisfy Americans with Disabilities Act (ADA) requirements, and therefore, ramps that meet ADA gradient criteria would be constructed near the northwest and southwest corners to connect the improvements to existing sidewalks. Roadway Improvements The proposed roadway improvements would result in a total width of 126 feet including: • 8-foot-wide bike lanes on both sides of the roadway • Three southbound lanes, 12 feet wide each CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 Page 3 • Three northbound lanes, 12 feet wide each • An 18-foot-wide landscaped median island • 5 !/2-foot-wide sidewalks on both sides of the roadway In the middle section of the roadway, the roadway would transition between the previously discussed typical sections to a modified width of 116 feet including: • A 6 '/2-foot wide bike lane on the west side of the roadway • A 5-foot-wide bike lane on the east side of the roadway • Three southbound lanes, 12 feet wide each • A 14-foot-wide landscaped median island • Three northbound lanes, 11 Vz feet wide each • 5 '/2-foot-wide sidewalks on both sides of the roadway Storm Drain Improvements Currently, the roadway in the project area exhibits erosion on the embankment on the east side of El Camino Real, pavement cracking and weathering, and bumps and sags. Storm water from the storm drains currently outlets at erosive velocities into a ditch east of the roadway. Storm drains within this area would be replaced and/or improved. The project includes the placement of erosion protection at the outlets of the storm drains within the ditch to remedy the erosion problem. The pavement for the roadway would be overlaid with asphalt concrete and/or replaced with a full structural section as necessary. Brow ditches are proposed along the east side of El Camino Real to prevent hillside storm water from flowing over the sidewalk and onto El Camino Real. Brow ditches will also be placed along the top of the retaining walls to prevent storm water flow over the walls. The sizes of the brow ditches would vary from approximately 12-inch minimum depth to 24-inch maximum depth. Grading/ Retaining Walls Minor grading would occur along the west side of El Camino Real to accommodate construction of proposed retaining walls. The height of the retaining walls would vary from 1-foot to a maximum of 15.5-feet high. The walls are proposed to be constructed with a boulderscape architectural treatment. The walls will be located approximately at the midpoint of the project, within the right-of-way of the road. Additional minor grading behind and at the top of the retaining walls would occur to construct brow ditches and drainage facilities. The width of the grading ranges from 5 to 8 feet. In the northeastern portion of the project area, approximately 300 linear feet south of Chestnut Avenue, there will be minor and major grading across four parcels (APNs 167-230-24, 25 and 167-154-15, 16) that would not result in impacts to existing housing or acquisition of property. The contour grading, at a 1.5:1 slope, would avoid having to construct tall walls on the existing steep slopes in this area. There is an existing paved driveway to access the property in this area, which will be re-graded and paved. The entire graded area will be hydro-seeded to prevent erosion and to make the slope more aesthetically pleasing and naturally appearing. Estimated grading quantities include 14,198 cubic yards (cy) of cut, 3,731 cy of fill with 10,467 cy of export. CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 Page 4 Landscaping/ Irrigation A Landscape Concept Plan has been prepared as part of the project to provide a transition between the ornamental landscaping and natural landscaping on either side of El Camino Real. The Landscape Concept Plan takes into account the City's El Camino Real Corridor Development Standards by incorporating a median landscape treatment that continues adjacent median designs. However, increased planting, and minimized hardscape, is proposed within the medians to off-set the additional hardscape of the proposed road and sidewalk improvements. This will minimize the increases in storm water run-off from the project and meet low impact requirements of the current storm water discharge permit issued by the San Diego Regional Water Quality Control Board. The Landscape Concept Plan includes low water use, minimization of fire hazards, minimization of visual impacts of the proposed retaining walls, and stabilization of disturbed slopes. Lighting Overhead lighting is proposed as part of the project. Lighting would be installed per applicable City standards for wattage and spacing. Eight light poles would produce up to 22,000 lumens and would be staggered at 300-foot intervals along both sides of the project section of El Camino Real. The light fixtures will be bell shaped and match the existing light fixtures on El Camino Real. Bus Stops One existing North County Transit District (NCTD) bus stop located on the west side of El Camino Real, just south of Chestnut Avenue, would be relocated as part of the project, although the specific location is in the process of being determined in concert with NCTD. No bus turnout will be constructed at the preferred location due to the difficulty bus drivers have pulling back into the lane from the bus turnout, per NCTD. A second bus stop exists along the east side of El Camino Real north of Tamarack Avenue. No improvements or alterations to this bus stop are proposed. IV. ANALYSIS The proposed project is subject to the following regulations: A. General Plan Circulation Element; B. Coastal Development Permit Regulations for the Mello II Local Coastal Program (LCP) Segment and the Coastal Resource Protection Overlay Zone (Chapters 21.201 and 21.203 of the Zoning Ordinance); C. Hillside Development Ordinance (Chapter 21.95 of the Carlsbad Municipal Code); D. Special Use Permit - Scenic Preservation Overlay Zone regulations (Chapter 21.40 of the Carlsbad Municipal Code and the El Camino Real Corridor Development Standards); and E. Habitat Management Plan (Chapter 21.210 of the Carlsbad Municipal Code). The recommendation for approval for this project was developed by analyzing the project's consistency with the applicable City regulations and policies. The project's compliance with each of the above regulations is discussed in detail in the sections below. As shown on the Coastal Development Compliance Table below, the proposed development is in compliance with all applicable regulations. CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3,2009 Page 5 A. General Plan Circulation Element Widening and improving El Camino Real to a six-lane, prime arterial standard is anticipated by the General Plan. This project would implement improvements to El Camino Real consistent with the General Plan. Further, the General Plan contains goals and policies on enhancing the City's image, beautifying the El Camino Real corridor, and improving automobile and pedestrian circulation in Carlsbad. Compliance with some of these standards of the General Plan is outlined in Table A below: TABLE A: GENERAL PLAN COMPLIANCE ELEMENT STANDARD PROJECT COMPLIANCE? Circulation Approve projects adjacent to El Camino Real only if the proposed project is consistent with the El Camino Real Corridor Development Standards Scenic Roadways (Implementing Policies and Action Programs C.7).

Mello II LCP Segment The project site is located within the Mello II Segment of the Local Coastal Program and is not in the appeal jurisdiction. The site is also located within and subject to the Coastal Resource Protection Overlay Zone (Chapter 21.203) of the Carlsbad Municipal Code. The proposed street improvements will not obstruct views of the coastline as seen from public lands or the public right-of-way, nor otherwise damage the visual beauty of the coastal zone. No agricultural uses currently exist on the site. The proposed construction is not located in an area of known geologic instability or flood hazard. Since the site is not located in close proximity to the coast, no public opportunities for coastal shoreline access are available from the subject site. 2.Coastal Resource Protection Overlay Zone The project is consistent with the provisions of the Coastal Resource Protection Overlay Zone (Chapter 21.203 of the Zoning Ordinance) in that the project will adhere to the City's Master Drainage Plan, Grading Ordinance, Storm Water Ordinance, Standard Urban Storm Water Mitigation Plan (SUSMP) and Jurisdictional Urban Runoff Management Program (JURMP) to avoid increased urban run-off, pollutants and soil erosion. The zone is intended to protect sensitive resources. It requires preservation of steep slopes with vegetation (dual-criteria slopes) with some exceptions. Encroachment into dual-criteria slopes is allowed when such CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3,2009 Page 7 encroachment is necessary for reasonable use of the property and when the encroachment does not exceed ten percent (10%) of the total steep (25% or over) slope area of the site. The area of the existing and proposed right of way in the coastal zone is approximately 365,045 square feet. Of that area, 24,461 square feet (or 6.7%) of steep vegetated slopes with protected biological species are impacted. The impact to this area is specifically required to construct the retaining walls to widen the southbound lane of El Camino Real. The retaining walls are necessary because the widening of the roadway cuts into the existing slope, much of which is bare due to the steepness of the slope. No development is proposed in areas of steep coastal bluffs. However, the project includes minor grading along the west side of El Camino Real to accommodate construction of proposed retaining walls to allow the road widening. Additional grading behind and at the top of the retaining walls would occur to construct brow ditches and drainage facilities. The proposed grading at the top of the walls would be very minor and would blend into the natural look of the existing terrain. On the east side of El Camino Real, both minor and major grading would occur in areas of past slope failure to stabilize the slope and re-establish the initial slope inclination and to replace a driveway access to the properties located at assessor parcel numbers 167-230-24, 25 and 167-154-15, 16. There are no prime agricultural lands near the site. There are sensitive vegetation communities within the Area of Potential Effects (APE) and there will be some unavoidable impact to biological resources. Specifically, the area of impact will be on the east side of El Camino Real in the areas where storm drain outlets are located. Storm water from the storm drains currently outlets at erosive velocities into a ditch east of the roadway. The majority of the existing storm drain system within the project limit is at capacity and therefore the project is proposing to replace and/or improve the existing storm drains and outlets. Rip rap, which would reduce erosive runoff velocities at the storm drain outlets, would be installed on the east side of El Camino Real. Within the areas where the storm drains outlet is where the majority of the impacts to sensitive habitat will occur. However, to reduce these potentially significant impacts to a less than significant level, mitigation measures contained in the project's Mitigation Monitoring and Reporting Program (MMRP), are required. Given the above, the project is consistent with the Mello II land use policies. C. Hillside Development Ordinance (Chapter 21.95 of the Carlsbad Municipal Code) The key purpose and intent of the Hillside Development Ordinance is to assure hillside conditions are properly identified and incorporated into the planning process, and to preserve and/or enhance the aesthetic qualities of natural hillsides and manufactured slopes of the land, minimizing the amount of project grading, especially in highly visible public places. The project is subject to this ordinance due to its proposed grading and construction of retaining walls along the western slope of the project. The applicant has submitted the required slope analysis and profiles that identify the slope conditions. The project area has numerous natural slopes with slope gradients over forty percent, slope heights that exceed fifteen feet, and slopes that are over 10,000 square feet in area. These characteristics would preclude development of these natural slopes per the Hillside Ordinance. Development on land designated for nonresidential development is not required to comply with the volume of grading and slope height requirements. Exclusions are also permitted for grading CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 PageS volumes and slope heights that are directly associated with circulation roadways and collector streets. Outside the coastal zone, hillside areas where a circulation element roadway or a collector street must be located are excluded from the hillside development and design standards of Section 21.95.120, as stated in Section 21.95.130 - Exclusions. The existing steep slopes on the west side of El Camino Real, approximately 1,200 feet south of the intersection of El Camino Real and Chestnut Avenue, and approximately 750 feet north of the intersection of El Camino Real and Tamarack Avenue, are to be cut back for retaining walls, which will allow this section of roadway to be increased to three southbound lanes and include a sidewalk and bike lane. The southernmost retaining wall will be 337 linear feet long with a height ranging from 1 foot to a maximum height of 7.5 feet. There is a small break between the two walls to provide for an existing driveway access. The northernmost wall will be 890 linear feet long with a height ranging from 2 feet to a maximum height of 15.5 feet. These slopes are to be reestablished at a near vertical surface, similar to the existing slope condition. The facade of the walls will have a boulderscape design and will be a similar color to other walls on El Camino Real. A sidewalk will be constructed in front of the walls. The sidewalk will connect with existing sidewalks on the north and south ends of the walls. Drought resistant landscaping will also be planted in front of the walls to soften the mass of the walls. To avoid having to construct tall walls on the existing steep slopes on the east side of El Camino Real, approximately 300 linear feet south of Chestnut Avenue, contour grading is proposed at a 1.5:1 slope. There is an existing driveway to access the property in this area, which will be re- graded and paved. The entire graded area will be hydro-seeded with a native seed mix to prevent erosion and to make the slope more aesthetically pleasing and naturally appearing. The area will have temporary irrigation until the plants are established. The project complies with the Hillside Development Ordinance as shown in Table C below: TABLE C: HILLSIDE DEVELOPMENT REGULATIONS COMPLIANCE STANDARD PROPOSED PLAN COMPLIANCE Grading volumes > 10,000 cu yds/acre allowed if the project qualifies as an exclusion or modification per Section 21.95.130 and 21.95.140. 14,198 cu yds/acre for the circulation roadway. Exclusion allowed for grading of circulation element roadways with an environmentally preferred alignment. A portion of the east side of El Camino Real, approximately 300 linear feet south of Chestnut Avenue, will be graded with a 1.5:1 slope to eliminate the need for a tall retaining wall. Yes Maximum manufactured slope height: 40 feet. Project contains existing slopes over 40 feet in height. However, no slopes or walls are proposed over 40 feet in height for El Camino Real, which is a Circulation Element roadway. Yes CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 Page 9 TABLE C: HILLSIDE DEVELOPMENT REGULATIONS COMPLIANCE CONTINUED STANDARD PROPOSED PLAN COMPLIANCE Contour grading: Required for manufactured slopes greater than 200 feet in length and visible from a circulation roadway, collector street or usable public open space. The area to be graded on the east side of El Camino Real will be graded with a 1.5:1 slope, and will be hydro-seeded to give the slope a more aesthetically pleasing and naturally appearing look. Yes Screening of slopes.The two proposed retaining walls would be constructed with a naturalized boulderscape architectural treatment that would look similar to existing conditions, and over time, the proposed drought resistant landscaping would mature and further soften the visual appearance of the retaining walls. Yes Landscape manufactured slopes consistent with City's Landscape manual. The wall accommodates landscape pockets to allow for vegetation plantings to help screen and soften the wall. Yes D. Special Use Permit (Chapter 21.40 of the Carlsbad Municipal Code and the El Camino Real Corridor Development Standards) A Special Use Permit is required for development within the El Camino Real Scenic Corridor Overlay Zone. The purpose of the overlay is to preserve the scenic qualities and maintain and enhance the appearance of the roadway through design concepts and development standards. This section of El Camino Real is defined as area 2, located from Chestnut Avenue south to the Country Store. The Corridor Development Standards identifies this area or segment as dominated by residential uses. Many of the standards discussed in the regulations pertain to such details as signage, setback from roadway, and building height, which do not apply to the proposed project. The project would incorporate other design features such as sidewalks and would not modify the existing identified design theme of suburban residential. Overall, the project would not conflict with the El Camino Real Corridor Development Standards. Table D explains how the project is consistent with the intent and applicable standards. CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 Page 10 TABLE D: EL CAMINO REAL CORRIDOR COMPLIANCE AREA 2 STANDARDS PROJECT COMPLIANCE Maintain and enhance the roadway appearance. Grading of the steep slope on the east side of El Camino Real would be more aesthetically pleasing and naturally appearing than having to erect a tall retaining wall in this area to accommodate the expanded roadway. The two proposed retaining walls on the west side of El Camino Real would be constructed with a naturalized boulderscape architectural treatment that would look similar to existing conditions, and over time, the proposed drought resistant landscaping would mature and further soften the visual appearance of the retaining walls. In addition, a native hydro-seed mixture will be sprayed on the disturbed slopes to give the area a more natural appearance. Yes Provide median island and parkway landscaping consistent with standards. Median island landscaping is proposed within the project and is consistent with Corridor Standards and the City's Landscape Design Guidelines. However, increased planting, and minimized hardscaping, is proposed within the medians to off-set the additional hardscaping of the proposed road and sidewalk improvements. This will minimize the increases in storm water run-off from the project and meet low impact requirements of the current storm water discharge permit issued by the San Diego Regional Water Quality Control Board. Yes Contour grading should be employed along the corridor to help retain the natural rolling hillside qualities. The area to be graded on the east side of El Camino Real will be graded with a 1.5:1 slope, and will be hydro- seeded to make the slope more aesthetically pleasing and naturally appearing. The contour grading is in place of a tall retaining wall. The contour grading will help retain the natural rolling hillside qualities of this area of El Camino Real. Yes CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 Page 11 E. Habitat Management Plan (Chapter 21.210 of the Carlsbad Municipal Code) The project's Area of Potential Effects (APE) covers approximately 16 acres. The area is surrounded by residential development. Above ground utilities exist along the length of both sides of the APE and a concrete-lined drainage ditch occurs along a portion of the project's west side. There is a small grove of mature eucalyptus trees located at the northwest corner of the APE, and south of the eucalyptus grove, there are several private residences with a gravel covered driveway connecting El Camino Real to asphalt-paved private driveways. The portion of the APE located south of the residences has steep slopes overlain by a relatively level vegetated area. A drainage ditch is located along the southern half of the east side of the APE. A cleared area is maintained along the eastern edge of the drainage. A paved sidewalk runs along the east side of the APE, most of which is open space with a mix of native and non-native grasses and low shrubs. The northern portion of the east side of the project is a vertical cutbank. Six existing storm drains on the east side of El Camino Real would be replaced and/or improved. The project includes the placement of erosion protection (rip rap) in the ditch to prevent erosion at the outlets. All impacts to sensitive vegetation communities would occur in these areas due to the repair work to the outlets and the installation of the rip rap, according to a Biological Resources Technical Report (Dudek 2007) that was prepared for the project. The report states that implementation of the proposed project would potentially result in the direct permanent loss of the vegetation community and non-natural land, which would directly impact sensitive wildlife species that depend on the native vegetation. Direct permanent impacts to vegetation communities listed as Habitat Management Plan (HMP) habitats in the City's HMP would be considered significant. The project's Mitigated Negative Declaration, discussed below, includes mitigation measures to reduce potential impacts to less than significant. Therefore, the proposed project would comply with the HMP guidelines and requirements and would be consistent with the Carlsbad HMP. V. ENVIRONMENTAL REVIEW Staff conducted an environmental impact assessment to determine if the project could have a potentially significant effect on the environment pursuant to CEQA Guidelines and the Environmental Protection Ordinance (Title 19) of the Carlsbad Municipal Code. The assessment determined the project has potentially significant impacts in the areas of biological resources, cultural resources, geology/soils, hazards/hazardous materials, hydrology/water quality, public services, transportation/circulation, utilities and service systems, and mandatory findings of significance. To reduce these potentially significant impacts to a less than significant level, compliance with the recommended mitigation measures is necessary. Based on the above, the Planning Director issued a Notice of Intent to adopt a Mitigated Negative Declaration (MND) for the project on October 30, 2007. A standard comment letter was received during the 30-day public review (October 30, 2007 - November 30, 2007) from the Native American Heritage Commission. In response, staff contacted Dave Singleton, Program Analyst with the Native American Heritage Commission. Staff faxed a copy of the Cultural Report for his review. Dave Singleton faxed a letter back stating he was satisfied with the mitigation and monitoring measures for Cultural Resources. The Native American Heritage Commission's letter and staffs response to the letter, are included as part of the Planning Commission Resolution for the Mitigated Negative Declaration. CDP 07-22/HDP 07-02/SUP 07-04/HMP 07-08 - EL CAMINO REAL ROAD WIDENING June 3, 2009 Page 12 The draft MND evaluated potential environmental impacts within the APE, which was assumed to be approximately 18.5 acres in size. This acreage was estimated under a worst-case assumption in the total acreage. Since the 30-day public review of the draft MND, the City has conducted additional engineering studies on the project, resulting in minor changes to the size and boundary of the APE. Three main changes were made to the APE. First, some areas within the APE were determined not to be required as part of the proposed road improvements, including the rectangular area south of Tamarack Avenue. Second, it was determined that an approximately 11,000-square-foot area, located on the east side of El Camino Real, will require grading and was therefore added to the APE. Third, a new storm drain improvement was added to the APE. As a result of these changes, the APE's acreage has been reduced from approximately 18.5 acres to approximately 16 acres. As a result, biological resource impacts to sensitive vegetation communities and jurisdictional areas have decreased from what was calculated in the Draft MND, and impacts to non-native grassland have been eliminated entirely. In addition, there is an increase in plantings, and minimization of hardscaping, within the medians to off-set the additional hardscaping of the proposed road and sidewalk improvements. This will minimize the increases in storm water run-off from the project and meet low impact requirements of the current storm water discharge permit issued by the San Diego Regional Water Quality Control Board. These changes are reflected in the attached memorandum from Shawn Shamlou, Environmental Planner for Dudek, dated December 15, 2008. The minor changes to the EIA Part II do not require recirculation of the Mitigated Negative Declaration since the changes are consistent with the description of "new information" in CEQA Section 15073.5(c)(4), which states recirculation is not required if "new information is added to the negative declaration which merely clarifies, amplifies, or makes insignificant modifications to the negative declaration."
