Recreation RECOMMENDED ACTION : DEPT.HD.&#f CITY ATTY- CITY MGR. b- Adopt Resolution No. da 1. ?,3 , approving the Zone 19 Community Park Master Plan and direct staff to proceed with environmental and permit processing. I ITEM EXPLANATION : Zone 19 Community Park is 24 acre park located in the Southwest Quadrant of the City and in the northern portion of the Aviara community (refer to Exhibit 2). Development of the park is outlined in the Parks and Recreation Element of the General Plan and is needed to meet the standards established under the Growth Management Plan (3 acres park per 1000 population). A project design team was formed that consisted of City staff from various departments as well as the City’s park planners, P&D Consultants. After data gathering, site analysis, and preliminary discussions of the initial program for the park, several conceptual layouts were produced for consideration. On November 20, 2000, staff presented an update on the progress of the master plan to the Parks and Recreation Commission. Staff explained two alternative park layouts and described the proposed public outreach program. An “open house/ public workshop” was held on December 7,200O at the Dove Library. The workshop was noticed using mailings and newspaper advertisements. Staff and the consultants were in attendance to explain the exhibits and to encourage input from the attendees. Comment forms were provided. Approximately 45 residents attended the open house and staff received valuable input from the citizens. Following the public meeting, the design team met and analyzed the public input. Along with the expertise of staff, they developed the final program for the park and recommended the “preferred alternative”. The proposed Zone 19 Park Master Plan is attached as Exhibit 3. Amenities include: One *Large soccer field w/ 2 smaller over-lay fields One *Ball field Two *Basketball courts (half court design) One Large tot lot Walkways and trails *will include sports lights. One Community center (approx. 17,000 square feet) One Large picnic area Two Restrooms One Maintenance bldg. Parking (approx. 175 spaces) The community center is intended to be different than the City’s other community centers. It will be slightly smaller and will not include a gymnasium. The vision for the center is to accommodate meetings, banquets, weddings, dance classes, and other like uses. Additionally, ’ there will be a “senior component” that will include a dedicated “senior family” room for “drop in” services that cater to seniors (e.g. library, meeting rooms, computer station, occasional health services, etc). The architecture is proposed to present a generally higher quality of aesthetics than the more purely functional designs of Calavera Hills and Stagecoach community center/gymnasiums. AB# 16: lo& Page 2 The recommended plan was presented to the Parks and Recreation Commission on January 22, 2001. After reading a letter addressed to the Commission advocating the development of a new pool complex as soon as possible, and hearing public comment from a citizen requesting the same, the Commission directed staff to investigate the possibility of incorporating a pool into the Master Plan. The incorporation of an Olympic size pool complex into the plan would result in the displacement of the soccer fields and either the community center g baseball field. Currently, the Capital Improvement Program outlines the future pool to be located in Alga Norte Park. For a variety of reasons, staff continues to believe that this is the best location for the pool and recommends the Zone 19 Community Park Master Plan be approved as presented. Finally, due to the “senior component” of the community center, staff presented the plan to the Senior Commission on February 1, 2001. The item was informational only, and the Commission generally approved of the plan. Should Council approve the Master Plan, staff will proceed with submittal of the plan for environmental review and processing of a Conditional Use Permit by the Planning Commission. Should Council wish to investigate including a pool at Zone 19 Park, staff will conduct additional design studies, and return to the Parks and Recreation Commission and/or City Council for further direction, ENVIRONMENTAL REVIEW No environmental review has taken place to date on the Zone 19 Community Park. The site itself was identified in the Pacific Rim (a.k.a., Aviara) Master Plan Environmental Impact Report (1987) as a future park site. Staff is requesting that Council approve the Zone 19 Community Park Master Plan and direct staff to submit the project for environmental review and processing of a Conditional Use Permit. FISCAL IMPACT: In the Fiscal Year 2000-2001 Capital Improvement Program (CIP), Council has appropriated the following funds: In the proposed FY 2001-2002 CIP, staff has presented a recommendation to increase the park construction budget (based on the preliminary cost estimates developed through the Master Plan process), as well as merging Phase I and II (to complete the entire park at one time). These funding issues are anticipated to be addressed by Council during the upcoming CIP review. EXHIBITS: 1. Resolution No.J&/=?3approving the Zone 19 Community Park Master Plan 2. Location Map 3.

It was determined that the overall character and quality of this park should be commensurate with the City’s existing community parks, but that the design program may vary. With each park developed in Carlsbad, better ways to provide amenities and analysis of which amenities best serve the public are incorporated into new designs. The vision for this park was one that included a balance of active and passive uses. The community center would not house a gymnasium (Poinsettia Community Park will ultimately have a gym), but would provide more opportunities for meeting rooms, a large multifunction space, and banquet accommodations. The aesthetics of the building would be upgraded from the existing, more institutional designs of the City’s existing coxnmunity centers/gym.nasiums to a warmer, more inviting architecture. After an initial vision and program were established, the second step of the planning process included a detailed analysis of the opportunities and constraints and feasibility of accommodating the desired facilities on the site. The findings of this step led to the following conclusions which were key factors in determining the park plan. 1. 2. 3. The park development should avoid impact to the sensitive habitat areas along the north and west edges of the park site. The topography of the site would not easily allow the creation of a continuous level area throughout the park. A site development approach which would include several terraces would allow more efficient use of the site and produce a more aesthetic park design. The lighted sports fields should be located in the west and central portions of the park. This conclusion was due to the topography and configuration of the park site and where there was the best opportunity to create pads of sufficient size to accommodate sports fields, and the goal to not locate the lighted fields immediately adjacent to the residential units east and south of the park. These conclusions provided a framework for several initial concept park designs. Ultimately two concepts were considered, Preliminary Concepts A and B (refer to Appendices A.2 and A.3). The Preliminary Design Concepts A and B prepared in the third step are differentiated by one major item, the location of the Community Building and the parking associated with the building. Each alternative was seen as having advantages and disadvantages, but the team evaluation and community workshop comments led to the conclusion that a variation of Plan B best achieved the objectives of the park. In the preferred master plan (frontispiece), the Community Building is on the west, allowing this important facility to take advantage of r Bi P&D Consultants, Inc. ES- 1 City of Carlsbad P:L4D&IlNUone 19Wirtcr PlmUl9 muter phdoc C C t- C r Zone 19 Community Park Master Plan northerly and westerly views to the surrounding hills and ocean. The picnic and play areas on the east allowed parking to be provided closer to those facilities. The third step also included the ongoing evaluation of draft space program for the Community Building and the functional relationships within the building. The fourth step involved conducting a public workshop/open house. This workshop was held on December 7,2000, at the Dove Library. Public input was recorded and integrated, where appropriate, into the design (refer to Appendix A.4). The fifth step included a continued refinement of the park plan in response to comments from staff and the public and the completion of a final Community Building space program and identification of key operational characteristics. With the determination that the preferred location of the Community Building was on a site with significant view potential, the concept architectural design was begun to take maximum advantage of that potential. The last step focused on the building design alternatives and confirmation that building design issues inherent to the site could be successfully addressed. Similar to the park planning process, there were key factors in determining the building plan. 1. The total site area available for the building is specifically defined by the site topography and adjacent habitat. Also important are setbacks from the habitat for fire safety. Buildings closer than 60 feet to the habitat areas may have limitations on the use of windows and other design features. The building program needed to be accommodated within the available area and allow for the desired windows, terraces, and other architectural features that would contribute to the quality of the building and experience of those who use it. 2. The building space program includes a variety of uses which could be going on at the same time. The four major use areas needed to be configured to be consistent with their unique use characteristics, and allow appropriate access to administrative and support areas. The building plan also needed to permit operational flexibility for the City staff, such as opening a portion of the building for after-hours use while securing other areas, and scheduling diverse activities simultaneously without conflict. The Community Building Concept Floor Plan (Exhibit J) places the four major use areas in the four quadrants of the building, based on their specific needs and use characteristics. The multifunction room is located in the northwest quadrant, the location of the best view, with access to a large outdoor terrace, restroom facilities, and a kitchen. The meeting room is located in the northeast quadrant, with access to a separate, smaller terrace and the kitchen. The senior drop-in center with senior family room is in the southwest quadrant, close to both handicapped and regular parking. It also has a separate terrace and a small restroom facility. The activity room, a space for active uses such as dance, martial art, and exercise classes, is in the southeast quadrant. The activity room has access to a second set of restrooms. All four major use areas are supported by the administrative area located near the entrance. P&D Consulfanfs, Inc.

The report documents the design process, the alternatives considered, and the preferred master plan for the park. The master plan was prepared and reviewed by a team comprised of City staff from the departments of Community Development, Recreation, Planning, Engineering, Public Works, General Services (Parks), and a consultant team comprised of a park planner, landscape architect, environmental analyst, and architect. The process included progress presentations to the Parks and Recreation Commission, and progress meetings involving all City departments who would have some responsibility for the construction and ongoing operation and maintenance of the park. The public had an opportunity to review the park planning process at an early date during the first Parks and Recreation Commission Meeting when two preliminary design concepts were under consideration. The public workshop was held at the Dove Library, and opinion forms were provided to allow specific comments to be submitted. The Parks and Recreation Element of the Carlsbad General Plan, and the City’s Growth Management Program, divide the City into four quadrants and 25 “zones” called Local Facilities Management Zones. The Zone 19 Community Park is located in the Southwest Quadrant, and is intended to be utilized for community-level park facilities serving the entire City, but more specifically, citizens of the southwest quadrant of Carlsbad (Exhibit A). The park site is located north of the intersection of Poinsettia Lane and Ambrosia Lane (Exhibit B). The 24.25-acre site was acquired as part of the Aviara Master Plan process and is on the northerly edge of that master-planned community. It is adjacent to residential development on the east and south, an industrial park to the north, and open space to the north and west (Exhibit C). The proposed facilities within the park are to serve a variety of outdoor activities including field sports, passive outdoor areas for individual and group play, and picnic areas. Also included is a Community Building with specially designed spaces for active uses such as dance, exercise, and martial arts, a space for meetings, a senior “family room”, and a large multipurpose area. The recreation facilities for the park and the support facilities, such as maintenance areas and parking, are consistent with the standards of the Recreation Department. The park program was also developed to help meet the facility standards adopted by the Parks and Recreation Commission. The park is intended to be an important new addition to the Carlsbad park system and provide for the increasing community recreation needs in this area of the City. The public comments and the evaluation by the City/consultant team led to the preparation of a third plan, a variation of one of the two alternative concept plans. This plan is identified as the preferred master plan. r P&D Consultants, Inc. 1 City of Carlsbad P:UDMlNU.me 19iMastcr PImEl muter plmdoc C C Zone 19 Community Park Master Plan This report contains both the preliminary design concepts and the preferred master plan. It also describes the key background information that affects the park plan and master plan level grading, landscaping, and utility plans for the park. All the park facilities are expected to be built in one phase, with the potential exception of the Community Building. The Community Building may be included in a later phase. The timing for the implementation of the park facilities and the Community Building will be addressed through the City’s Capital Improvement Program. r P P P r r 1 P i r P r r r lm P&D Consultants, Inc. 2 City of Carlsbad P P 7 P P P P P no scale Southwest Quadrant I 19 I Local Facilities Management Zones City of Carlsbad Regional Location Exhibit A page 3 no scale y9 1 Community Park Vicinity Map Exhibit B Page 4 F Community Park F / Aerial Photograph f Exhibit C Page 5 P Zone 19 Community Park Master Plan P P C - r C c- f r Section 2 Existing Conditions The park is located in the northern part of the City of Carlsbad’s Local Facilities Management Plan Zone 19 at the intersection of Poinsettia Lane and Ambrosia Lane. Its relatively high elevation provides excellent distant views to the north and west. The overall park site is 24.25 acres, with approximately 5 acres of that sensitive habitat areas. The majority of the remaining area of the site is currently being used for agriculture. The site is surrounded by an industrial park on the north, residential development on the east and south, and open space on the west. There are 116 feet of elevation change from the highest to the lowest point within the park boundary. The steepest slopes, some over 25%, occur in the areas of sensitive habitat. Generally, the west part of the park drains to the south and the east part drains to the north. There is a Carlsbad Municipal Water District easement with an 1 g-inch water line and 12-inch recycled water line on site that connects to adjacent developments. It is expected that a portion of the easement and water lines will need to be relocated as a part of the park development. The opportunities and constraints are illustrated on Exhibit D. The biological resources are also illustrated on the exhibit and discussed below. Biological Resources An overview biological resource survey was conducted on the property to characterize habitats and document existing conditions. Because of the limitations of this survey, it was not intended to provide census information regarding potentially occurring sensitive plants and wildlife. The agricultural and disturbed habitats that dominate the central portion of the site are unlikely to support sensitive or rare plants or animals; however, the native chaparral habitats on the edge of the site may provide habitat for a variety of potentially occurring flora and fauna. Based upon this biological resources mapping, it was concluded that all preliminary design concepts should avoid potentially significant impacts to the sensitive resources. The Preferred Master Plan was evaluated, and there are no direct impacts to any sensitive biological resources. However the following mitigation measures could be used to avoid potential indirect impacts: l Provide a physical barrier between the construction activities and the sensitive resources to eliminate inadvertent impacts to off-site sensitive resources. l Direct the storm water runoff from the park away from natural resources area. IM P&D Consultants, Inc. 6 City of Carlsbad P:UDMlNUoae 19iMarter PlnnUl9 master plm.doc Zone 19 Community Park Master Plan C l Provide a permanent physical barrier with signage (i.e., “No Trespassing”) around all areas of the park that approach native habitats to reduce human intrusion into biologically sensitive areas. l Design all lighting such that it is oriented to the active use areas and the sensitive resources are shielded.

Literature review, record search, field survey, and testing identified two prehistoric sites within the park property. Both sites have been tested to determine site significance. The first site was identified as significant, and mitigation of impacts was achieved through the completion of a data recovery program. The second site was tested and identified as not significant. Given the presence of a significant cultural resource that may contain burials, monitoring during grading is recommended. 000 PdGD Consultants, Inc. 7 City of Carlsbad PAADMINEone 19iMmter Plan\Zl9 master plaadoc r’ 1 * 1, @ ‘1 ! ’ -cn P 1: 3 P r- P Zone 19 Community Park Master Plan Section 3 Initial Design Concept Studies The two initial design concepts were based on a park development program that included : P P P P P l l l l l l l l l l A full-size lighted soccer field; Two soccer practice fields that overlay the full-size field; A lighted softball/baseball field; A lighted basketball court; A large tot lot; Picnic areas; A Community Building with a Senior Drop-in Center; A park maintenance facility; Restroom building(s); and Parking to support the facilities. The functional relationships between these facilities were analyzed, and these are surnmarized on Exhibit E. With a combination of active and passive recreation uses to be accommodated in the park, it was determined that the lighted, active use areas should be located on the west and north away from the adjacent residential areas. Both concepts locate the soccer fields west of Ambrosia Lane, and the softball field north of the Ambrosia Lane cul-de-sac. It was also determined that the Community Building should be located with some visual and functional separation from the sports fields. The 5,000~SF maintenance facility will provide storage for materials and equipment for maintenance of the park. It will also provide office space and restrooms for the maintenance personnel. Both concepts locate the maintenance facility at the southwest comer of the park that allows for right-in/right-out access to Poinsettia Lane. The restroom building will also provide a storage area to local sports organizations. Both concepts also eliminate the existing cul-de-sac terminus of Ambrosia Lane to allow for a more continuous landscaped entry drive into the park. Preliminary Design Concept A locates the parking on the perimeter of the site to maximize the useable park area and to act as an organizing element. The Community Building is located at the east side of the park with adjacent parking shared with the softball field. A single separate restroom building is located adjacent to the play fields and the tot lot, and the main passive recreation and picnic area is located at the high point of the park with views to the northwest. Preliminary Design Concept B locates the Community Building at the high point of the park to take advantage of the views. The entry drive connects directly to the Community Building and a parking lot that is shared with the soccer fields. The tot lot and passive recreation and picnic areas are located at the east side of the park, with additional parking shared by the P&D Consultants, Inc. 9 City of Carlsbad P:UDMINZoac INaster Plani muter ph.doc C C P Zone 19 Communitv Park Master Plan softball field.

(See the Preferred Master Plan, Exhibit F, and the Park Program and Parking Requirements, Exhibit G.) The modifications to the plan included changing the grading of the site to more closely balance the earthwork cut and fill. As a result, the softball field and picnic area are closer to the same elevation, allowing better circulation between the two. This also creates a landscaped slope backdrop at the park entry. Other changes included making the basketball court a double half court, which allowed it to be more easily integrated into the plan. Also, the restroom building serving the soccer fields was moved to the west side of the fields. The preferred site plan places the park facilities at different elevations, creating a terraced site design. The Community Building is at approximate elevation 322 feet. The center of the soccer fields to the south is about 9 feet lower at elevation 3 13 feet. The center of the softball field is elevation 306 feet, and the tot lot and picnic area are elevation 300 feet. The total elevation change over the developed park acreage is about 30 feet. The terraced park design and the relationship of the park to the surrounding area are illustrated in Exhibit H. The most significant refinement to the plan is the development of the walkway system. Pedestrian access into the park will be primarily from the end of Ambrosia Lane, and secondarily from the southwest comer of the park site. At the Ambrosia Lane entry, a staircase and pedestrian ramp is shown to provide direct access to the soccer fields and to the Community Building. A walkway will parallel the entry drive and the drive to the east parking lot, and a universally accessible walkway/trail connects the softball field, basketball court, picnic and passive recreation areas, and the tot lot and can be used to walk around the perimeter of the park. Also at the east side of the park, a walkway connects to a potential gate which would provide access to the park from the adjacent neighborhood. 000 r r r P&D Consultants, Inc. 12 City of Carlsbad F?lADhiINUone 19\Munr PIan\Zl9 muter plur.doc Zone 19 Community Park Master Plan P r r Exhibit G Park Program and Parking Requirements Program Activity Adult Soccer(‘) Sofiball Practice Soccer(‘) - 2 Basketball Court Tot Lotc2) - 1 large Community Building Maintenance Facility’3’ Picnic Areas (l-acre size) Restroom Buildings(4’ Total Parking Required Total Parking Shown (‘) It is assumed that the two youth/practice soccer fields will be in use at the same- require more parking than the single adult field.

The three primary steps have been the preparation and refinement of a space program for the buildings, particularly the Community Building, identification and evaluation of the site for each structure within the overall park master plan process, and the preparation of an initial floor plan and concept elevations for each building. Architectural Space Program The architectural program for the Community Park is comprised of three building types: Building Approximate Size The detailed design program for the Community Building is illustrated in Exhibit I. The initial program was prepared by the Parks and Recreation staff. The refinement of that program and the determination of key functional relationships occurred throughout the first half of the master plan process and involved the entire City/Consultant Team. Building Site location The overall master plan process for the park produced Preliminary Design Concepts A and B. These are differentiated by one major item, the location of the Community Building and the parking associated with the building. Plan A placed the Community Building on the east side of the site, and parking is located south of the building (Appendix A.2). Plan B places the Community Building on the west side of the site, the highest point, and parking is located between the Community Building and the soccer fields (Appendix A.3). The evaluation of the Preliminary Design Concepts A and B focused particularly on the feasibility of successfully siting a Community Building on the westerly site. The gross area P&D Consultants, Inc. 16 City of Carlsbad P:UDMINUone 19Wuter PlnnU19 muter plna.doc Zone 19 Community Park Master Plan C r C C available of the westerly site is approximately 1.1 acres. For fire safety purposes, the standard building setbacks from the native vegetation is 30 feet if there are no windows, and 60 feet if there are to be windows. The evaluation included plot plan and building footprint studies to determine if a structure of a size sufficient to satisfy the building space program and with the desired window treatments could be sited in accordance with Plan B. The studies concluded that the westerly site could accommodate the Community Building. Each of the Preliminary Design Concepts A and B was seen as having advantages and disadvantages, but the team evaluation and community workshop comments led to the conclusion that a variation of Plan B best achieved the objectives of the park. In the preferred master plan (Exhibit F), the Community Building site on the west allows this important facility to take advantage of northerly and westerly views to the surrounding hills and ocean. Architectural Design The building space program includes a variety of uses which could be going on at the same time. The four major use areas are configured to be consistent with their unique use characteristics, and allow appropriate access to administrative and support areas. The building plan also is designed to permit operational flexibility for the City staff, such as opening a portion of the building for after-hours use while securing other areas, and scheduling diverse activities simultaneously without conflict. The Community Building Concept Floor Plan (Exhibit J) places the four major use areas in the four quadrants of the building, based on their specific functions and support requirements. The large multipurpose room is located in the northwest quadrant, the location of the best view, with access to a large outdoor terrace, restroom facilities, and a kitchen. The meeting room is located in the northeast quadrant, with access to a separate, smaller terrace and the kitchen. The senior drop-in center with senior family room is in the southwest quadrant, close to both handicapped and regular parking. It also has a separate terrace and a small restroom facility. The activity room, a space for active uses such as dance, martial art, and exercise classes, is in the southeast quadrant. The activity room has access to a second set of restrooms and a small terrace on the front of the building. All four major use areas are supported by the administrative area located near the entrance. The Community Building Concept Elevations (Exhibit K) illustrate a Spanish/Mediterranean design theme consistent with the prevailing architectural themes throughout Aviara. This is a conceptual design intended to show the general form and character of the building. This final design process will warrant a more focussed design effort and will articulate the architecture to a greater degree. 000 P&D Consultants, Inc. 17 Cify of Carlsbad PAADhlIMZone MMashr PIanU19 muter ph.doc P P ?

The existing cul-de-sac terminus of Ambrosia Lane will be removed and the street will transition to a driveway connecting into the park. The access to the maintenance facility will be from a right-in/right-out driveway connecting to Poinsettia Lane. This access point will be for maintenance vehicles only. Utilities The proposed utility services are illustrated on Exhibit L. Sewer, water, electrical, gas, and cable television connections to the Community Building, Restroom buildings, and the Maintenance Building can be made from the existing utilities located within Ambrosia Lane and Poinsettia Lane. In some cases new public facilities will be required to extend the existing systems from Ambrosia Lane and Poinsettia Lane to the park site. There also exists an existing 30-foot wide water easement to the Carlsbad Municipal Water District that traverses the park site in an east to west direction. There exists an 18-inch steel domestic water main and a 124nch recycled water main within the easement. These two facilities either connect or are planned to connect to the adjacent developments. It is assumed that a portion of the existing easement, domestic water main, and recycled water main will need to be removed and/or relocated as part of the park project. Storm Runoff and Storm Drain Facilities Storm runoff from the park site in the existing pre-developed condition drains north into the natural areas, south into Ambrosia Lane and Poinsettia Lane and west into undeveloped areas. Storm runoff from the park site (i.e., parking lots, playing fields, open areas, and areas adjacent to the buildings) in the developed condition will respect, as much as possible, the pre-developed drainage patterns. The ultimate storm drain design of the park will have to consider the constraints of draining into the natural resource areas and the capacity of the existing storm drain facilities located in Ambrosia Lane, Poinsettia Lane, and the existing downstream facilities. It is presumed that a portion of the developed park site may be diverted south, away from the natural resource areas (Exhibit L).

The landscape concept is illustrated on Exhibits M and N. The groundcover on the existing manufactured slopes along Poinsettia Lane and Ambrosia Lane will be supplemented with informal tree and shrub massing to soften their manufactured character. Similarly, the existing manufactured slopes at the east and southeast corner of the park, adjacent to the existing residential areas, will have supplemental tree and shrub massings to screen views of the parking area. The parking areas will be planted with canopy trees to provide shade and mitigate heat gains from the paved areas, and provide a unifying and identifying element. New manufactured slopes on the perimeter of the park will be planted with native and low- water-use plants that will blend with the existing on- and off-site natural areas. Barrier shrubs will be planted on the manufactured slopes of a size and spacing to discourage intrusion of park patrons into the sensitive habitats of Oak Woodland, Southern Maritime Chaparral, Scrub Oak Chaparral, and Coastal Sage Scrub-Disturbed. The Community Building will be landscaped primarily with lawns and groundcovers so the views to the north and west will not be interrupted. This will also help to mitigate any fire hazards from the adjacent native vegetation. Some trees will be used on the south side of the building and in the terrace area to provide shade and visual softening of the facade. The majority of the park will be planted in lawn for the soccer fields and the softball field, the passive recreation areas, and the picnic areas. Trees will be planted to define the use areas and to provide shade to the picnic areas. Based on the definitions in the City of Carlsbad Landscape Manual, there are four planting Zones within the park boundary. Zone One - comprises the most water- and maintenance-intensive areas and includes the turf ball fields; picnic areas; and high-use areas around the Community Building. Zone Two - comprises the areas of refined maintenance and design and includes the entry area slopes and planting within the parking areas. Zone Three - includes naturalizing and transitional areas such as the revegetated manufactured slopes. Zone Four - includes the existing native undisturbed landscape.

The purpose of this survey was to document existing biological conditions on site, and to identify any sensitive biological resources that may constrain development here. Habitats mapped onsite include coast live oak woodland, scrub-oak-dominated maritime chaparral, southern maritime chaparral, coastal sage scrub - disturbed, non-native grassland, agriculture, ruderal, disturbed, landscaped, and developed. Potential jurisdictional waters exist at the northern portion of the site, where topographical features convey water to a cement-lined brow ditch which occurs along the northern property boundary. The City of Carlsbad (City) Habitat Management Plan (HMP) requires some form of mitigation for all of the habitats mapped within the project site (with the exception of landscaped and developed). Mitigation for impacts to coast live oak woodland can only be achieved by in-kind habitat creation (no net loss); scrub-oak-dominated maritime chaparral and southern maritime chaparral would require in-kind replacement (i.e., offsite acquisition) at a ratio of 3: 1. Coastal sage scrub - disturbed habitat (gnatcatcher - unoccupied in this case) would need to be replaced at a ratio of 1: 1. Non-native grassland would require compensation at a ratio of 0.5: 1, and disturbed/agricultural habitats could be mitigated through a fee charge. Sensitive plants observed on the park site include De1 Mar manzanita (Arctostaphylos glandulosa ssp. crasszjblia), Nuttall’s scrub oak (Quercus dumosa), summer holly (Comarostaphylos diversifolia ssp. diversifolia), wart-stemmed ceanothus (Ceanothus verrucosus) and Palmer’s goldenbush (Ericameria palmeri ssp. palmeri). De1 Mar manzanita is a federally endangered species. All of the above (with the exception of Palmer’s goldenbush) are HMP Covered Species. f F?ADM~NIZO~C 19!bioletter.doc C r C - Mr. Jason Martin January 22,200l CITY OF CARLSBAD Page 2 A general biological resource survey was conducted on the property to characterize habitats and document general existing conditions. Because of the limitations of this survey, it was not intended to provide census information regarding potentially occurring sensitive plants and wildlife. The agricultural and disturbed habitats that dominate the site are unlikely to support sensitive or rare plants or animals; however, the native chaparral habitats on site may provide habitat for a suite of potentially occurring flora and fauna. Based upon this biological resources mapping, P&D implemented a design that would avoid potentially significant impacts to the sensitive resources. The preliminary design plan was evaluated, and there are no direct impacts to any sensitive biological resources. However, P&D recommends the following mitigation measures to avoid potential indirect impacts: l Provide a physical barrier between the construction activities and the sensitive resources to eliminate inadvertent impacts to off-site sensitive resources. l Direct all runoff away from natural resources area. l Provide a permanent physical barrier with signage (i.e., “No Trespassing”) around all development that approaches native habitats to reduce human intrusion into biologically sensitive areas. l Design all lighting such that it is oriented to the active use areas and the sensitive resources are shielded.
