INTRODUCTION This Environmental Impact Report (EIR) has been prepared for the City of Carlsbad to evaluate the potential impacts of the construction of Stagecoach Park. The park is designated in the La Costa Master Plan and the City's Park and Recreation Element as a community park. The Daon Corporation (developer of the La Costa Community) has dedicated a portion of the site to the City and is in the process of dedicating the remaining portions. The schematic development plan evaluated in this EIR was prepared for the City by the Daon Corporation. Additional alternatives are also evaluated. Issues addressed in this EIR include those identified by the City Planning Department staff when the Initial Study for the project was completed. Additional issues identified during the preparation of the EIR have also been included. Although the "proposed project" evaluated in this EIR is a "schematic master plan", it contains sufficient detail to allow a reasonable assessment of potentially significant environmental impacts that may be associated with the construction of the park. The City staff determined that an EIR is required for this project pursuant to Section 15065 of the State "Guidelines for the Implementation of the California Environmental Quality Act", as of January 1984 to assess the impacts of the current proposed amendments. This EIR has been prepared in accordance with the California Environmental Quality Act of 1970, the State guidelines for implementation of the act (the "State CEQA Guidelines") as adopted by the California Resource Agency (amended through January 1984), and the City of Carlsbad Guidelines for the Implementation of CEQA of 1970. The determination that the City of Carlsbad is the "lead agency" is made in accord with Section 15367 of the State CEQA Guidelines, which defines the lead agency as "the public agency with the principal responsibility for carrying out or approving a project." The environmental impacts which could result from the project were identified by the City staff through completion of an environmental checklist and were determined to be sufficient to warrant preparation of an EIR. An effort has been made during the preparation of the EIR to contact affected agencies, organizations and persons who may have an interest in this project. Information, data and observations resulting from these contacts are included where relevant. Responses to Notices of Preparation (NOP) are contained in Appendix A. Agencies or interested persons not contacted or who have not responded to the request for comments about the project during the preparation of the DEIR will have the opportunity to comments during the period of circulation of the Draft EIR. Comments received by the City on the Draft EIR together with the responses to such comments will be included in the Final EIR in accordance with the guidelines of the State and the City. I-i Relevant reports and other reference materials from which data or conclusions contained in this EIR have been drawn are listed in Section VII, "References". The numbers in parentheses in the text of this EIR, (e.g., A-i; B-3) refer to the document of that number listed in Section VII which supports the statement or finding. These documents are available for public review at the central offices of the City of Carlsbad Planning Department. The State's adopted Guidelines for Implementation of the California Environmental Quality Act require that each EIR must contain eight areas of description and analysis. These subject areas, and the corresponding sections in this Supplemental EIR where they are addressed, are listed below. Required Description and Analysis Section of EIR 1.

SUMMARY A. Preface This section presents a review of the principal findings of this Environmental Impact Report. During the report's preparation, several important factors basic to the design and proposed uses of the subject park proposal became apparent. These center on the need for additional active recreation uses in Carlsbad and their inclusion in the current Stagecoach Park plan, while at the same time preserving and enhancing the site's natural and historic features. The relationship between these two factors was considered throughout the assessment and evaluation portions of this report. The alternatives section contains two design concepts which specifically address the retention of the most important natural and historic features without sacrificing the active recreation uses. B. The Project This Environmental Impact Report (EIR) is prepared for a development proposal for Stagecoach Park in the southeast portion of the La Costa community prepared by the Daon Corporation. The schematic master plan provides for active and passive recreational facilities. The active facilities include five baseball/multi-use fields, two tennis courts, two basketball courts and a community center (gymnasium). Group picnicking is located within the active area and casual picnic areas are included in the passive area. Other facilities include a concession stand and restrooms. C. Environmental Issues The following summarizes the areas of potential environmental impact and mitigation measures evaluated in this EIR (See Table S-i): 1. Biological Resources: Implementation of the proposed park design will result in the elimination of the majority of wildlife uses now on the site. Re-establishment of the riparian associated vegetation is possible over a five year span, however the proposed grading will not allow for the recovery of the fresh water marsh habitat. Construction of the park and adjacent residential developments will narrow the existing streambed, and the loss of the habitat will be significant. Degradation of the site's natural features will occur even if there is no on-site development as a result of increased urbanization in the surrounding area. Mitigation measures include alternative designs which would reduce the area to be developed for recreation purposes, re-establishment of the woodland and emergent vegetation in a re-aligned channel, and acquisition and preservation of an equivalent sized area upstream which contains woodland and adjacent open field habitat. II-1 2. Drainage/Soils: Implementation of the proposed park design will result in the construction of a grass-lined open channel above and south of the existing streambed if Alternative Is of the La Costa Racquet Club Tentative Map resolution is implemented. A hydrology study has been completed which shows that the proposed channel would carry the anticipated flow of 712 cfs. If Alternative lb of the La Costa Racquet Club Tentative Map is chosen, a crib wall will be constructed immediately north of the existing streambed. The resulting channel may be too narrow to carry the flows calculated in the hydrology study. 3. Archaeological/Historical Resources: The adobe ruins of the Ybarra home are intended to be preserved within the park as a historical interest point, according to Parks Department staff. This is not clearly shown on the present site plan and grading, as proposed in the preliminary plans, would likely result in removal of the ruins to accommodate the recreational facilities. This impact can be mitigated by revising the grading plans to assure the preservation of the ruins. There are no above ground remnants of the barn left. Mitigation of the barn site includes excavating, mapping and locating the structure in relation to the house. 4. Land Use Compatibility: The park will be compatible with the community to be developed in the surrounding area. Facilities provided by the park will be a public benefit to future residents. No adverse land use impacts are anticipated to result from construction of the park. 5. Traffic/Circulation: Vehicular access to the park site will be taken from Mission Estancia. Pedestrian access will be available through two walkways extending into the residential area north and east of the park. While a single vehicular access point as currently proposed would adequately serve the park, it would be much more desirable to have two access points. This would help to alleviate possible congestion and mitigate safety concerns. Proposed parking could be deficient if active use of all facilities in the park occurs at the same time. Mitigation measures include having the park access road, assuming there is only one access road, being two lanes in each direction; alignment of the access road with Calle Acervo; pedestrian and vehicular access to adjacent residential areas; and preparation of a detailed parking analysis once specific park uses have been finalized to insure the adequacy of the parking area. 6. Noise/Lighting: Noise and lighting effects generated by recreational activities within the park may affect nearby residences. Noise will be the most noticeable in the evening and on weekends. Night time lighting may also impact the residences closest to the park. These effects can be reduced by limiting the evening hours of operation, controlling sound level of public address systems, and shielding of ball field lighting. 11-2 D. Alternatives to the Proposed Project The EIR analyzes several alternatives to the proposed project. Included are two alternatives (i.e., Alt. la and Alt. lb) for treatment of the streambed adjacent to the La Costa Racquet Club's southern slope area. These are discussed in the appropriate sections throughtout this report. Section V, Alternatives contains a discussion of several other project options. The "No Project" alternative would keep the site in its natural state except to the degree that the site would be modified by surrounding development. Two alternatives consider redesign of the park to provide essentially the same facilities as the proposed project design, while having less of an effect on the stream channel area and historic resources. The alternatives section also considers more intensive urban uses of this site (i.e., commercial, industrial, or residential uses). E. Analysis of Long-Term Effects The primary long-term effect of the proposed project is the commitment of the site to public park uses. The cumulative long-term effects of the park and other nearby development are: *Reduction of wildlife habitat; *Increase in traffic, which will impact streets in the vicinity of the park; and *Minor increase in noise levels due to increases in traffic levels. 11-3 TA&E S-i SUMMARY OF FINDINGS I.

Project Location Stagecoach Park is located in the southeast portion of the La Costa Community, within the City of Carlsbad, California. La Costa is located 2.6 miles inland from the Pacific Ocean and approximately 6.5 miles southeast of the commercial center of Carlsbad (see Figure 1). The park site is a short distance southeast of the La Costa Avenue and Rancho Santa Fe Road intersection (see Figure 2). The park will front on the planned Mission Estancia (see Figure 3). B. Project Background The La Costa Master Plan was first adopted by the Carlsbad City Council on September 5, 1972 (Ordinance #9322). The latest revision to the Master Plan was adopted on October 5, 1982 (Ordinance #9647) (A-i, p. I-i). The La Costa community contains 5,584 acres, of which 5,287 acres are located within the boundaries of the City of Carlsbad. The remaining portions of the community are located in the City of San Marcos and the County of San Diego. Approximately 3,200 acres of the territory within Carlsbad have been developed, approved for development, or are in the process of being approved (A-i, P. I-i). Stagecoach Park is designated as area SE-11 in the Master Plan and is to be dedicated to the City as required by the existing Parks Agreement (resolution No. 6830) (A-i, p. V-5, V-b). Approximately 20 acres have been transferred to the City and an additional 8 acres are in the process of dedication. In 1981, the Daon Corporation (developer of La Costa) had a schematic master plan prepared for Stagecoach Park. The objective of the study was to assist the Park and Recreation Commission and its staff in developing improvement designs for Stagecoach Park. Two alternative designs were prepared as well as preliminary cost estimates for site grading. The design concept for southeast portion of La Costa provides for the widest diversity in housing types and lifestyles structured around a community core. Medium and medium-high density residential development is clustered within this core and is linked with southwest portion of La Costa and a large community park by an extensive open space system (A-i, p. Ill-I). Stagecoach Park is located within the community core area (see Figure 4). The community core area is designated as a Special Treatment Area in the Carlsbad General Plan (A-i, p. 111-3, 111-6). The City's General Plan states that a Specific Plan should be prepared for the Special Treatment area. The La Costa Master Plan fulfills this requirement and provides that future development be reviewed in accordance with the La Costa Development Plan Review Process.

This 496 unit subdivision is located adjacent to the Stagecoach Park on the north. The approval provides two alternatives for treatment of the streambed adjacent to La Costa Racquet Club's southern slope area. Alternative la provides for the developer to construct the slope at a ratio of 2.5:1 (as shown on the TM) if the City determines that the existing riparian area in Stagecoach Park can be eliminated. In exchange for allowing for granting slope rights onto City property, the developer shall agree to construct such drainage improvements at the base of the slope as determined by the City Council (A-13, P.2). Alternative lb provides that if the City has not made a determination concerning the riparian area by April 23, 1985, the developer may elect to construct a combination cribwall and slope in lieu of the slope identified in Alternative la. The developer and the City will adjust the property line between the tentative map and the park site so that the slope and cribwall will be entirely within the developer's property. Any land lost from the park site shall be replaced by the Daon Corporation on an equal square foot basis for other land to be included in the ultimate boundaries of the park (A-13, p.3). If a cribwall is constructed, it is to be suitably landscaped with appropriate materials so that an aesthetically pleasing appearance shall result when viewed from the park. Such landscaping shall be permanently irrigated and maintained by a homeowner's association. If a cribwall is constructed, a biologist shall be present on-site during construction and a detailed restoration plan shall be prepared by the biologist and implemented by the developer if appropriate (A-13, p.3). C. Project Characteristics Community parks are defined by the City of Carlsbad as a facility of 20 to 50 acres designed to serve the broad recreational needs of several neighborhoods" (A-3, p. 17). Stagecoach Park is to be built on a 28-acre site dedicated for park purposes by the Daon Corporation (A-i, p. 111-8). The schematic master plan for Stagecoach Park provides for both active and passive recreational facilities (see Figure 5). The active facilities include five baseball/multi-use fields, two tennis courts, two basketball courts and a community center (gymnasium). Group picnicking is located within the active area to allow for organized festivities to take place in conjunction with sporting events. The passive area is intended to serve as a casual picnic area where informal play activities can take place. Other facilities provided in the park include a concession stand and restroom. 111-6 1-4 )-1 PARK ENTRY Ii.EV 2ID30 MISSION FIGURE 5 Schematic Site Plan 30 The park will be developed in four phases. The phases are: Phase I (1985-86) Design total park. West Section - 15 acres a. Grading; b. Landscaping; and c. Site development. -lighted multi-use playfields, -picnic/passive areas, -parking lot (80 spaces), -tot lot -historical preservation, -hardcourt play areas, -tennis courts, -maintenance building/restroom, and -walkways. East Section - 13 acres a. Grading; and b. Site development. -multi-use lighted play fields, -parking lot (60 spaces), -entry road, -restroom, -concession stand, -walkways, and -landscaping. Phase II (West Center Section) (1987-88) a. Construct a 10,000 sq.ft. community center. Only one vehicle entry/exit is provided for the park to permit optimum park supervision. Parking areas have been located in the interior of the park to allow for greater supervision and to allow for the maximum buffer planting along Mission Estancia. Walks within the park are sufficiently wide to allow for service and emergency vehicle access (A-2). Additional walks will extend from the northwest and southwest corners of the project area. These trails are part of a system which connects this proposed park with other trails and open space areas. They are not a part of this project. 111-8 To create maximum active recreation area, the natural contour of the land is to be reshaped for playing fields and other active recreational uses. The amount of cut and fill required to construct the park is estimated to be 222,000 cubic yards (cu. yds.) of cut and 190,000 cu. yds. of fill. Consequently, 32,000 cu..yds. of earth will have to be removed from the site. The intent of the park development plan is to reduce the City's current deficiency in athletic fields and to preserve the ruins of the Ybarra adobe house in a "historical area." The remains of the adobe barn will be removed by the grading operation. The schematic plan designates a portion of the park as an "historical area." However, the area is not precisely located on Figure 5 and will have to be moved to the west. Within this area a plaque and display are to be erected to memorialize the site. Definitive plans are to be developed by the Parks Department concerning the content and arrangement of the historical area (B-7). D. Statement of Objectives The objective of the City's Parks and Recreation Element is to establish a Parks and Recreation Development Program for the City that provides optimum recreational opportunities for all the residents (A-3, p.1). The development of Stagecoach Park as a community park furthers the implementation of this objective by providing: ° A major active-use area that will be operated on a regular schedule; o Less active-use and passive areas requiring a minimum level of maintenance; and ° Use areas for organized groups (A-3, p. 10). In addition, Action Plan 1.4:2 of the Parks and Recreation Element specifies that the City will "develop a preservation program for the existing stagecoach stop at Stagecoach Community Park as a mark of historical identity to the community" (A-3, p. 8). A specific objective of the park plan is to establish such a preservation program.. A "Playing Field Analysis" was completed by the Parks and Recreation Director in August, 1984 (A-14). This document has been endorsed by the Parks and Recreation Commission as defining the need for additional athetic fields within the City. The report recomends standards for the ratio of fields per 1,000 population and identifies the following deficiencies in the number of fields available: Field Classification Youth Softball/Baseball Adult Softball Youth Soccer Adult Soccer Youth Football Adult Football # Deficiencies 4 10 2 2 1 0 111-9 The report further notes that: (1) public demand for league playing fields is increasing; (2) there is a lack of lighted fields; (3) all existing sites are overcrowded; and (4) Carlsbad School District fields are used at their maximum capacity. The Stagecoach Park development plan will meet some of the existing deficiencies by providing the following facilities within the park: play apparatus; turfed multi-use playing fields; gymnasium; tennis and/or racquetball courts; and on-site parking (A-3, p. 20). E. Relationship to Regional and Local Plans The construction of Stagecoach Park implements a portion of the Revised Parks and Recreation Element of the General Plan (A-3). The dedication of the site also implements the public parks provision of the La Costa Master Plan (A-i, p. V-5). The City General Plan and the La Costa Master Plan are the only adopted plans relating to park facilities in the City of Carlsbad. F. Related Projects Stagecoach Park is the only public park planned to be constructed on the southeast side of Rancho Santa Fe Road within the City of Carlsbad. No other parks are planned in the adjacent areas. The La Costa Master Plan provides for a high school site directly across Mission Estancia from Stagecoach Park. When constructed, recreational facilities at the school presumably will be available for public use during non-school hours. However, the construction of this school is not planned in the foreseeable future (B-4). C. Approvals Required The developer of the La Costa Racquet Club project will be required to obtain permits from the U.S. Fish & Wildlife Service and the U.S. Army Corps of Engineers to construct the slope, or cribwall, in the watercourse. A 1603 agreement will have to be executed by the California Department of Fish and Game and the City of Carlsbad. 111-10 IV. ENVIRONMENTAL IMPACT ANALYSIS A. Biological Resources Environmental Setting: The Stagecoach Park site lies in an area of gently sloping hills with an intermittent stream flowing along the northern edge of the site. The watershed of the stream above the park site is about 600 acres. Upstream of the site an oak woodland of Coast Live Oaks (Quercus agrifolia) occurs in association with the stream. On-site the stream has a willow woodland of Arroyo Willow (Salix lasiolepis) in the upper area, and a freshwater marsh, dominated by rushes (Scirpus californicus) in the lower area (Figure 6). Two large and prominent eucalyptus trees (E. globulus) occur near the lower portion of the on-site channel. Aside from a mesquite (Prosopis glandulosa var. torreyana) and prickly-pear cactus (Opuntia ficus-indica), the remaining area is vegetated by non-native ruderal vegetation, indicating past over-grazing of the area. The stream is part of the Batiguitos Lagoon watershed. The stream and its associated riparian vegetation serve as a focus for regional wildlife activity. The surface water draws wildlife to the channel. The emergent, mesic-associated vegetation creates a cover habitat which shelters certain bird species for resting, nesting and feeding. The willow woodland provides higher relative humidities, resulting in a favorable habitat for certain small birds, such as black phoebe and possibly the Bell's vireo, as well as amphibians. The section of the linear, riparian system occurring on-site is an important link in this regional resource. Development of downstream areas has considered the importance of this habitat and has attempted to maintain wildlife habitat along its course. The open field habitat, although of little importance botanically, serves as foraging habitat for area predators, such as coyote, bobcat and hawks. Deer also may range into the area from brush-covered slopes to the east. Relationship of the Setting to the Proposed Project: The proposed project is an active recreation-oriented community park. Several baseball diamond fields are planned as the major feature of this community park. The construction of residential dwellings in areas surrounding the proposed park site will generate a substantial group of park users, especially children and juveniles. Many park users will be involved with the baseball and soccer activities. Many may also interact with the streambed. Although development of the adjacent residential areas is not a part of the proposed project, such development will result in a loss of a large open field habitat. The relative size of the open habitat in the proposed park site is small in comparison to that planned for residential development. The proposed park project involves regarding the site and realigning the present streambed. IV-1 FIGURE 6 Vegetation Features Stagecoach Park Site 3a) No Scale An approved residential project on the adjacent, northern boundary, the La Costa Racquet Club condominiums (CT 84-7), will potentially involve the proposed park plan. The impact of this condominium project relates to an option given ihe project proponents by the City Council to either (1) grade the entire area in and north of the creek channel and thereby relocate the drainage or (2) place a crib wall adjacent to the present streambed. The first of these alternatives involves alteration of a natural water course and would require an agreement with the California Department of Fish and Game and probably the U.S. Army, Corps of Engineers. Under the preliminary grading plan for the parks, the City of Carlsbad would be required to obtain these permits or agreements if the City and developer opt for the crib wall design. Environmental Impacts: Implementation of the proposed park site design will result in the elimination of the majority of wildlife uses now available on the site. Its impact will also depend upon which option is chosen by the adjacent project developer and City. Riparian Habitat The loss of these wildlife habitats must, however, be evaluated in light of proposed adjoining projects. The most immediate is that of a (Alternative la) slope placement or (Alternative lb) crib wall on the north side of the site, in association with the La Costa Racquet Club condominia (CT 84-7). Alternative la The stream will be altered by grading the northern slope to a 2.5 to 1 slope to the relocated stream bed where a 4:1 grasslined slope and a rockline channel will be created. The possible effect from the alteration of the stream hydrology is increased siltation, eventually ending up in Batiguitos Lagoon. Filling of the riparian wetland associated with this grading alternative is a significant biological impact and was so stated in the environmental documentation of the adjacent residential development. For this reason of significance the developer chose to look at the option of Alternative 2. Alternative lb Placement of a crib wall would allow retention of the riparian habitat. Some minor disturbance of this stream might occur as short-term impacts associated with construction of the structure. The impact of implementation of this alternative, relative to the wetland habitat, would not be significant. Further it would not involve the need for processing of State 1603 (1601 in the case of a City of Carlsbad application) or possibly a federal 404 permit from the Corps of Engineers. The alternative would leave woodland habitat which would attenuate noise and visual disturbance from park use and the woodland streambed will remain a visual ammenity. Iv-3 Open Field Habitat Loss of the open field habitat by development of the remainder of the proposed park site (but more significantly by development of adjoining areas) will eliminate foraging habitat for wildlife and probably cause the relocation of the red-tailed hawk which now uses the on-site eucalyptus trees. The remaining open space area which now occurs downstream is probably not adequate to maintain this bird in the area since its quality has been reduced by the cosmetic landscaping treatment it has received. The proposed project impact on open space is considered not significant but does represent an incremental loss which contributes to a significant loss of this habitat. Mitigation Measures: A No Project alternative for park site development would not avoid the impacts possible from slope grading or crib wall placement associated with the adjacent residential development. The open field habitat would be maintained by such an alternative however. The continued residential development in the vicinity would result in increased use of this riparian and open area by children and juveniles. Such an unattended use would fatally degrade the habitat insofar as wildlife use is concerned. Loss of riparian and open field wildlife habitat by implementation of the proposed park design can be compensated in several manners. (1) Redesign A redesign to allow for retention of the stream-associated function of the site and still permit sports recreation-oriented use would reduce biological impacts to riparian habitat. The long-term viability of the stream-associated wildlife habitat will be jeopardized by the close proximity of children and juveniles who would be drawn by their curiosity to the site. Fencing might prevent random access, but in any case considered, the habitat quality will deteriorate from what it is now. Reduction of the project's sports recreation scope and redesign of the project to retain the drainage as it occurs now would involve a 100 foot buffer distance from the centerline of the stream thread. (2) Restoration Alternative C-i discussed in the alternatives section of the DEIR would involve restoration of a woodland which, initially, would have a lower wildlife value and no assurance of full establishment, especially with children and juveniles drawn into the area. Re-establishment of the riparian-associated vegetation, especially cat-tails (Typha) and willows is possible over, perhaps, a five year span. The proposed, reworked land contours would not allow recovery of the marsh habitat, however. This restoration, presumably, would be an aspect of a 1603 or 1601 Agreement, as well as a 404 permit resolution. The encumbrance of these additional permitting procedures and their associated mitigation measures would add substantially to the cost of the project. IV-4 (3) Off-Site Preservation The proposed project will reduce riparian habitat areas. Acquisition and preservation of an equivalent sized area upstream which contains woodland and adjacent open field habitat may be possible. Typically compensation actions require 3 or 4 times the area involved as compensation. Suitable land of such a magnitude does not appear in the immediate vicinity of the project. This sort of off-site mitigation might involve another drainage system. IV-5 B. Drainage/Soils Environmental Setting: The proposed part site contains approximately 26 acres lying east of Rancho Santa Fe Road roughly one quarter of a mile south ot La Costa Avenue. A riparian habitat exists along the northerly boundary that carries surface drainage from the east through the property to the west. This drainage basin is known as the Encinitas Creek Basin. Short grasses cover the rolling hills of the site, sloping northwesterly to the limits of the heavily vegetated riparian habitat along the north boundary. The highest elevation is around 240 feet above mean sea level at the southeasterly project boundary with the lowest elevation being around 160 feet above mean sea level at the most southwesterly corner of the site (See Figure 7). 1. Surface Drainage Approximately 712 cubic feet per second of surface drainage can be anticipated during a 100 year frequency rain storm within the existing drainage channel along the north boundary ot the site. This quantity was taken from a Drainage Analysis prepared for the So-Cal Development Plan immediately north ot the site (A-il). The Drainage Analysis is a H.E.C. I analysis of a grass lined open channel drainage structure that corresponds to Alternative la channel described in Section lll.B. The contiguration evaluated proposes a grass lined channel with a base width of 16 feet, side slopes of 4 to 1 constructed at an average channel slope ot .4. The depth of flow, using a 712 C.F.S. rate equated to slightly over 4 feet with a surface width ot slightly over 49 feet. The flow of 712 C.F.S. calculated in the Drainage Analysis was based on "rull" development in the drainage basin, including Stagecoach Park. 2. Soils and Geology No known site specific soils or geological investigation has been performed for the proposed park development, immediately to the north, however, is the La Costa Racquetball Club (So-Cal) development proposal that has been approved by the City of Carlsbad. Due to the proximity or this development to the park proposal, it is reasonable to assume that similar soils and geological conditions would exist at both sites. Preliminary Soils and Geological Report for the So-Cal Development has been utilized to evaluate the potential impacts in the in-situ soils and geological conditions could have on the park development plan (A-12). A review of the site exploration map contained within the soils and geological investigation identifies three boring holes very near the proposed Stagecoach Park. They are B-6, B-5 and B-4. An itemization of the findings are as follows: B-6 - Location - Northwest Boundary of Park Lands Elevation - 14 A.M.S.L. + IV-6 Estancia / L.. 41 '0 .- '1 -4 / / r— Cut 4 FIGURE 7 Topography No Scale Surface natural soils to three feet consists of silting clay, with high moisture content. Del Mar Formation, interbedded claystone, siltstone and sandstone was found from 3 to 18 feet deep. Some water seep occurred at 9 and 17 foot depths. Interbudded sandy claystone and silty sandstone was found from 18 to 30 feet in depth. B-5 - Location - Northerly Boundary of Park Lands, Elevation - 202 A.M.S.L. + Surface natural soils to 2.5 feet consisted of sandy clay with numerous angular volcanic pebbles and cobbles. Santiago Peak volcanics exist from 2.5 feet to 10 feet in depth where refusal occurred. B-4 - Location - Northeasterly of the Park Proposal, Elevation - 220 A.M.S.L. + Alluvium, sandy clay to 10 feet in depth with rapid water seep at 8 feet and the boring abandoned at 10 feet due to caving. Based upon the above borings, as well as the others performed by Geo Soils, it was their conclusion that the La Costa Racquetball Club development was geotechnically feasible. There was no evidence of major landsliding nor other geological hazard that would preclude development. The likely materials available for fill construction on site would include natural soil, alluvium, Del Mar formation claystone and the Santiago Peak volcanics. High moisture content of the claystone materials may pose some grading difficulties and may be mixed with other on site materials to obtain the desired moisture content. Environmental Impacts: 1. Surface Drainage A conceptual grading plan has been prepared (see Figure 8) for the Stagecoach Park Schematic Master Plan (see Figure 5). The existing drainage pattern of the park site is to the west and north. This drainage pattern will be the same after the grading is completed. The conceptual park grading plan is intended to provide the maximum area suitable for athletic fields. If Alternative la is selected for the La Costa Racquet Club (see Section III.B) the streambed will be reconfigured (See Fig. 9). As noted above, the drainage analysis calculated a flow 712 cfs. through the channel. This calculation includes the development of Stagecoach Park (B-8). The effect of reconfiguring the streambed will be to narrow it into a 58-foot grass-lined channel slightly elevated and south of the existing streambed. Maintenance of the channel will be required to keep it clear of obstructing vegetation. Further, the existing riparian habitat will be removed by this alternative (see Section IV.A).

I'I.SO' Figure 9 Cross Sections No Scale If Alternative lb is selected for the La Costa Racquet Club (see Section III.B) the existing streambed will remain and a crib wall will be constructed immediately north of the streambed. The conceptual park grading plan will narrow the drainage channel along the northern park boundary. When coupled with the crib-wall placement proposed for the La Costa Racquetball Club, the resulting channel may be too narrow to carry the flows as calculated in the Drainage Analysis. However, the City's intent is to revise the grading plan if the curb wall is constructed. 2. Soils and Geology Assuming that the La Costa Racquetball Club soils report can be utilized as a guide to the soils in the park area, it appears that no significant soil or geological hazard exists that would preclude the park development. The potential exists, however, to encounter hard formational soils that may require blasting. Groundwater is anticipated within the alluvial areas of the site and may pose some grading difficulties. Mitigation Measures: 1. Surface Drainage A number of options are available to accommodate the surface flow across the proposed Park site. They are as follows: a. Leave the existing channel in its present state and avoid grading within this area. b. Construct a grass lined, concrete lined, or rock lined channel within the site of an appropriate size and configuration to adequately carry this flow. c. Construct a subsurface drainage system, at an appropriate size, of reinforced concrete or other similar structural materials. The benefits and disadvantages of the above drainage options are discussed below. Drainage Option 1 If the existing drainage channel is determined to be of significant biological value, then this alternative (see alternative C-i, page V-2) is the most appropriate. Based upon the existing channel configuration it is suggested that grading occur no closer to the flow line of the creek than about 40 feet. This rough number was derived from estimating a 100 year storm flow depth of 4 to 5 feet with a channel width of roughly 30 to 40 feet. A detailed drainage analysis of the existing flow characteristics of the natural channel should be done in conjunction with the detailed IV-11 development plans for the park in order to verify the validity of the above suggested grading limits. Leaving the drainage course in its natural state will reduce the development costs of the park development. This option, however, reduces the available gross park area for development of the playing fields and associated facilities. A Preliminary Grading Study should be performed in order to determine if all of the proposed facilities could be constructed within the reduced useable park area if this option is adopted. Draina2e Option 2 This options calls for the construction of an open channel configuration either grass lined, rock lined or concrete lined. Each of these can be constructed at a large variety of configurations dependent upon cost and land area constraints. The proposed channel should be evaluated with regard to land area constraints as well as cost. The use of rock rip-rap siding or concrete lining will increase or decrease the channel size respectively. Again, a detailed evaluation should be performed in conjunction with the development plan for the site. Should this option be adopted, the biological value, if any, of the existing riparian habitat would be destroyed. 2. Soils and Geolo A detailed soil and geological investigation is recommended for the verify the assumptions made in the Impacts section above. Volcanic could be encountered requiring difficult ripping or the potential blasting at depth. Fill slopes should be constructed at gradient 2-1/2:1 (horizontal to vertical). Cut slopes within the Del Mar claystone should be constructed at gradients of 2-1/2:1. If thes are less than 10 feet in height, they may be constructed at gradi 2:1. Cut slopes in the Santiago Peak volcanics may be constructe gradients of 1-1/2:1 with the approval of Carlsbad's City Enginee IV-1 2 site to rocks C. Archaeological/Historical Resources Environmental Setting: The project site is located in a region which contains a large number of archaeological sites, as well as containing ruins of historic interest. The La Costa Land Company properties, within which the project site is located, have been the subject of intensive archaeological surveys. The results of these surveys are contained in two documents; "An Intensive Archaeological Reconnaissance of the La Costa Land Company Property, Carlsbad, California" (A-8); and "Archaeological Test Program at Site W-945, La Costa S.E., Carlsbad, California" (A-9). Both of these studies are on file at the City of Carlsbad Planning Department, and should be referred to for detailed background data on the archaeological context and resources of the La Costa area. There are over 60 archaeological sites known in the vicinity of the Batiquitos Lagoon. These sites range in significance, are representative of several cultural groups, and span a period of many thousand years. The local region is also of historic interest. The area was probably crossed by both the Portola expedition of 1769 as well as the de Anza expedition of 1776. The principal route (El Camino Real) between the Missions and presidos of "Alta California" is within close proximity to the subject property. Cattle ranching in the local area, which continues today, dates to the ranchos of the early nineteenth century. Relationship of Setting to the Proposed Project: There are no known archaeologic sites within the boundaries of the proposed project. A 40 by 45 meter archaeological site, known as W-945, is located adjacent to the southwestern border of the subject property (A-8). This site was originally recorded by Russell Kaldenberg in 1975. It was tested in 1976 and was found to be of "moderate significance" and recommended for a limited data recovery program. This program, which involved the excavation of several one-meter square pits was completed in 1984 (A-9). The results of this later study are not currently available. Development of the proposed project will not impact this archaeologic site. The ruins of an adobe house and barn are located on a rise in the central-eastern portion of the project site. The house ruins consist of several low adobe walls, while the barn remains are limited to a rectangular mound. The adobe ranch house was built by Andreas Ybarra in the mid-1840's. It is known to have served as the headquarters for the Rancho Ybarra in 1842. By the mid-1860's the ranch house had become a stage stop for rest and food, on the two-day trip between San Diego and Los Angeles. The barn was probably built during this time. In the late 1860's the ranch was sold to Joseph S. Mannasse and Marcus Schiller of San Diego. They expanded the house and stocked the rancho with cattle. Successful completion of the railroad between San Diego and Los Angeles, in 1887, ended the stage runs. The property went through several owners, and for a brief period in the late 1880's, was used by group of German emigrees, who formed a colony called Olivenhain. The ranch house, barn, and related wood frame structures associated with the Olivenhain Colony appear to have been abandoned sometime shortly before or after the turn of the century. IV-13 Impact: Additional information of the history of the ranch house can be found in two reports which are on file at the City of Carlsbad Planning Department; "The Andres Ybarra Ranch House And the Rancho Las Encinitas" (A-6), and "Colony Olivenhain". The rancho house site has been recorded by the San Diego Museum of Man, and has been given the site designation of W-948. It has not been designated by federal state or local authorities as a historic landmark. The Stagecoach Park site was originally selected by the City of Carlsbad for a park, at least in part, because of the Ybarra ranch house ruins. Both schematic alternative plans for the park include a small historical area within which the ruins of the ranch house are to preserved. Representatives of the City's Parks and Recreation department have indicated that the ruins for the Ybarra Ranch house are to be preserved within the proposed park (B-7). This preservation would not include the traces of the barn. Despite this, review of preliminary grading plans indicate that it is doubtful that grading of the extent needed to develop the proposed park facilities could be undertaken without destroying the ranch house ruins. Plans have not been finalized to the point where it is possible to verify this conclusion. In addition, no current plans address the disposition the house remains. At the present time the house ruins are surrounded by a chain link fence to prevent vandalism. This is consistent with current City policy, as expressed in the City's Parks and Recreation Element, which calls for preservation of the ranch house ruins. As a result, destruction of the ranch house remains would probably require a General Plan Amendment. A letter from the Carlsbad Historical Society, expressing their desire for the preservation of the Ybarra Ranch House remains is included as Appendix B. In addition, the Historical Society also recommended that the slope adjacent to the ranch house ruins and the nearby stream be retained for passive recreation use. Mitigation Measures: Preservation of the ranch house ruins presents several problems. The remains of the adobe walls are extremely fragile and are being rapidly eroded by the weather. At a minimum, some type of shelter or roof would have to be constructed over the remains to prevent further destruction. Provision would also have to be made to prevent public access to the wall remants. This could either entail retention of the present fence or construction of another barrier. A bronze plaque describing the ranch house and stage stop was made several years ago for installation at the site once development of the park had occurred (B-7). Preservation of the barn remains is probably not warranted given their condition. The barn should be mapped and located in relation to the ranch house. An archaeologist should also be present during any earthmoving activities likely to impact the barn area. IV-14 Any development proposal which would destroy the ranch house remains would require more extensive mitigation measures. At a minimum this would mean archaeoigoical mapping and survey as well as text excavations. Additional excavation might be needed, based on the results of the initial excavations. A specific condition of approval for the La Costa Master Plan states that "All archaeological or historic areas which cannot be satisfactorily salvaged shall be covered or preserved as open space" (A-i, p. II-1). IV-15 D. Land Use Environmental Setting: The Stagecoach Park site is located in the La Costa Southeast community (A-i, p. III-0. This community is planned for a wide variety of housing types structured around a community core. The northern portion of the community core is designated for professional uses by the La Costa Master Plan (see Figure 4). Medium and medium-high density (4-10 & 10-20 du/ac.) residential development is clustered within the community core between the commercial area and Stagecoach Park. North and west of the community core is an existing medium-high density residential area of the La Costa Southwest community. Development to the south and east of the core is planned for very-low density estate type housing. Immediately south of the park site, across Mission Estancia, is a designated high school site (see Figure 4). The agreement between the San Dieguito Union High School district and the Daon Corporation requires the District to purchase the site prior to 1995 (B-4). The district's intent is to purchase the site sometime after 1990 and to construct a school when funding becomes available and a sufficient number of students reside in the area. The school is planned for a student population of 2500. Currently the district has no high schools located within the City of Carlsbad. A junior high school site is located in the La Costa Southwest community and will probably be developed prior to the high school site. Within the North City West area of the City of San Diego the district is establishing joint uses of athletic fields with the City. District representatives indicate a willingness to establish the same type of joint use activities with the City of Carlsbad (B-4). Relationship of the Setting to the Proposed Project: The park development master plan illustrated in Figure 5 will provide multi-use athletic fields, tennis courts, basketball courts, a community center and passive recreation area. These uses are compatible with the residential areas surrounding the park site. The parking areas have been located in the interior of the park to allow for greater supervision and to allow for more buffer planting along Mission Estancia (A-2). Two extensions of the park will provide walkways from the commercial and residential areas to the interior of the park. A dense tree planting program is envisioned in the master plan for the periphery of the park. This planting will help buffer the park's daily activities from nearby residences. Environmental Impacts: The park will have beneficial land use impacts because it will provide active and passive recreational facilities for the adjacent medium-high density housing areas. Walkway access from the housing areas will increase the accessibility of the park facilities. Long-term future beneficial impacts can result if the park and school facilities are jointly developed and operated. No significant adverse land use compatibility impact are anticipated to result from the development of the park. Other impacts (e.g., noise, lighting, traffic, etc.) are addressed in their respective sections of this EIR. IV-16 The relationship of Stagecoach Park to the proposed high school south of Mission Estancia, as well as to adjacent residences, is an important land issue concern. Both the high school and most of the adjacent residences will be at higher elevations than the Park. As a result, the park's playing fields and other active recreation areas will be visible from the surrounding area. The elevation is such that landscaping, even after the trees mature, will not completely shield the park from the surrounding area. The visual impact is impossible to quantify without more detailed grading plans and site design concepts, both for the proposed park and for the surrounding area. The proximity and visibility of the park in relation to the proposed high school strongly suggests that the park will become a focus for activity by high school students. Vehicular and pedestrian traffic are likely to be the most noticeable effects. A number of the medium and medium-high density residental units approved for development to the north of the project site will have a clear view of the Park. The clearest views will be from south oriented windows and patios of those units which face the Park. Other units in these residential developments will be shielded to a greater or lesser extent depending on the elevation and the location of residential buildings to the south of them. The actual extent of this land us impact cannot be determined without more detailed information on the proposed residences. Adherence to mitigation measures described in the noise, lighting and traffic sections of this report should reduce any potentially significant adverse impacts to acceptable levels. Mitigation Measures: No land use compatibility mitigation measures are required. Alteration of the sites shape by trading some of the area in its westerly portion for an equal area in the eastern portion, would provide additional land for active recreation uses. This would in turn help ameliorate various land use related concerns, including historic site, preservation and retention of the stream channel; see Section V, Alternatives for greater detail. IV-17 E. Vehicle Circulation and Parking Existing Traffic Conditions: The information presented in this section is primarily drawn from studies completed by Weston Pringle and Associates. The site is currently vacant and Mission Estancia has not been constructed. Rancho Santa Fe Road is a north-south arterial to the west of the site which is in various stages of development. In the environs of the site, Rancho Santa Fe Road is currently two lanes with full development being completed as adjacent land develops. Existing daily traffic on Rancho Santa Fe Road is approximately 5,700 vehicles adjacent to the site. The intersection of Rancho Santa Fe Road and La Costa Avenue, northwesterly of the site is currently signalized. Figure 10 illustrates the existing and proposed road system in the area. Trip Generation: Due to the very general nature of the planned use of the park, estimating trip generation must also be general. The City of San Diego utilizes a rate of 40 daily trip ends per acre for a developed park. SANDAG utilized a rate of five trip ends per acre for parks in the Carlsbad Transportation Study Traffic Model. The Institute of Transportation Engineers publication "Trip Generation" indicates a rate of six daily trip ends per acre based upon limited data. Since the schematic plans indicate an active program, it is recommended that a rate of 40 trip ends per acre be utilized. On this basis, the park would be anticipated to generate 1,120 daily trip ends. No data are available relative to peak hour trip generation. Peaks do occur before and after major activities (little league, soccer, etc.); however, these do not generally coincide with normal Street peak hours. These peaks also vary in magnitude and time of occurrence with the season and sport or activity. Trip Assignment: Trip distribution for the park would be directly related to residential intensity and location. Review of the General Plan Land Use Element and La Costa Master Plan was utilized to estimate a geographic distribution for the park. This distribution is illustrated on Figure 11. By applying these distributions to the daily trip generation estimate, project trips were assigned to the street system as indicated on Figure 11. This assignment provides a basis for the traffic analysis portion of this study. Traffic Impact Analysis: The project would generate an estimated 1,120 daily trip ends which is an increase over the 140 daily trip ends contained in the SANDAG Traffic Model for Carlsbad. Due to the local nature of park trips and their minor impact during street peak hours, this difference would not be anticipated to result in a significant traffic impacts. Daily traffic volumes at buildout of the General Plan on Mission Estancia are projected by SANDAG to be 4,500 at Rancho Santa Fe Road and 2,100 at La Costa Avenue. With the project, these volumes would increase to 5,200 and 2,400 respectively. Mission Estancia is classified as a Secondary Arterial in the General Plan and has a daily capacity of 10,000 to 20,000 vehicles. The projected daily volumes with the project are well within the capacity of the Street.

Recreational uses generally occur during non-work periods so that their peak hours are separate. Peak hour trips from Stagecoach Park would not be anticipated to impact the circulation system of the area. Vehicular access to the park was reviewed with respect to traffic operations and safety. The projected daily volume of 1,120 daily trips can be accommodated by the single access indicated on the schematic plans. It is recommended that two lanes be provided in each direction between Mission Estancia and the first internal intersection. This will reduce the potential for traffic congestion during peak ingress and egress periods. Projected daily volumes from the park would not be sufficient to justify signalization of the entrance intersection with Mission Estancia. The schematic site plans indicate that the intersection of the park access road would be located 20 to 50 feet west of the future Calle Acervo intersection while a topographic map and grading plans show the park access and Calle Acervo in alignment. An off-set is not desirable from a traffic operations or safety viewpoint. The park access should be aligned with Calle Acervo in the final design. The intersection of Mission Estancia and Rancho Santa Fe Road will ultimately require signalization as the area develops. Signalization of this intersection would not be required solely by park generated traffic; however, the park traffic would contribute to the need for signalization. The site plan indicates that all vehicular access would be from Mission Estancia. Calle Acervo would provide area access as well as Mission Estancia. Pedestrian and bicycle access should be provided to the residential areas on the west, north and east of the park. This reduces vehicle travel and provides improved safety for pedestrians and bicycles. Parking Impact Analysis: Off-street parking adequacy is a critical factor for parks of this type. Inadequate parking results in vehicles parking on-street on arterials or residential areas which create traffic operational and safety problems. As previously stated the plan indicates 153 off-street parking spaces and the alternate plan includes 140 off-street spaces. Parking needs for parks of this type are directly related to the activity schedule and overall program. Since specific data relative to park use is not available, this analysis is based upon assumptions. As an example, a little league team has 14 players and, for the younger teams, it is not uncommon for all parents to attend. This could result in 28 vehicles per field plus vehicles for coaches, officials, conscessionaires and others. With five fields available, a potential demand for 140 parking spaces can be developed. If a concurrent activity occurs in the community building or the passive areas, a parking deficiency could develop. In addition, the period between the finish of one set of games and start of another could produce several shortages. Summer evenings with ball fields, tennis courts, basketball courts and community building being utilized along with passive areas could also produce parking demands that exceed the supply. IV-21 The preceeding discussion indicates that there is a potential for a parking deficiency with the plan. It is recommended that the final plans be analyzed based upon the actual use program to determine the off-street parking needs. Current planning is insufficient with respect to off-street parking. The principal findings of this traffic study are as follows: 1. The park is estimated to generate 1,120 daily trip ends with a negligible number occurring during the Street peak hours. 2. The total of buildout and project traffic would not exceed the daily capacities of the adjacent streets. 3. A single vehicular access would be adequate to serve the park and projected volumes would not indicate a need for a signalization of the access road/Mission Estancia intersection. 4. While the Rancho Santa Fe/Mission Estancia intersection will ultimately require signalization, the park would not trigger the need on its own. 5. The plan does not indicate a potential for traffic impacts upon local residential streets in the area. 6. The proposed parking supply could be deficient if active use of all facilities in the park occurs simultaneously. Mitigation Measures: The following measures are recommended to mitigate potential traffic impacts of the Stagecoach Park project. 1. The park access road should have two lanes in each direction from Mission Estancia to the first internal intersection. 2. The park access road should be aligned with Calle Acervo. 3. Pedestrian and bicycle access to the adjacent residential areas should be maintained. 4. Preparation of the final plans should include a detailed parking analysis based upon a specific use program for the park to insure adequacy. 5. Inclusion of an additional ingress/egress point if possible. IV-22 F. Noise and Lighting Environmental Setting: At the present time the park site does not contain any noise or light generating activities. Future development plans for the area include residential uses on all sides of the park site. The residential areas are generally at an elevation ten to twenty or more feet above the park site. Consequently, when these areas are developed the housing units will be looking down into the park area. The La Costa Master Plan addresses noise attenuation and establishes physical design standards to attenuate the adverse impacts of noise to the extent possible (A-1, p. 111-12). Relationship of the Setting to the Proposed Project: Noise and lighting pollution generated by park activities will affect the surrounding residential areas. Noise generated by the activities proposed for the park will generally be of short duration bursts of noise rather than continual noise. Noise generated by recreational activities occurring in the park will be primarily daytime and evening noise except for night-time activities related to the use of the athletic fields. Traffic generated noise on Rancho Santa Fe Road and Mission Estancia will be a more persistent noise than park generated noises. On a sustained level, the traffic noise will probably equal, if not exceed, the noise level of the park. Lighting of the athletic fields for night-time use will be directly visible from the residential areas surrounding much of the La Costa Southeast community. Impacts: The residential areas immediately surrounding the park site may be adversely impacted by noise and light pollution resulting from park activities. The severity of these impacts cannot be quantified at this time. However, in a general sense, these impacts will probably approximate the noise and lighting levels associated with large high schools that have both day and night-time athletic events. Weekend and evening noise will be most noticeable to nearby residents, and the sporatic nature of the noise will increase the perceived level of noise. Mitigation Measures: The following noise mitigation measures are listed in the La Costa Master Plan: o Streets schools and park should be designed to achieve a depressed elevation separation from adjacent areas; and 0 Active-play areas should be surrounded by passive park areas. Illustrative examples of noise attenuation measures are contained as Exhibits 111-17 to 21 in the La Costa Master Plan (A-i, pgs. 111-30-32). Additional mitigation measures recommended for inclusion in the park plan are: o Play field lighting should be fully shielded, carefully directed, and constructed in accordance with the City's Building Code; IV-23 o Play field lighting should be prohibited between 9:30 p.m. and sunrise in wintertime and between 10:30 p.m. and sunrise in summertime. This requirement applies to other tennis court areas in La Costa; ° Amplifier levels on public address systems should be established; and Athletic events should be prohibited between 10:00 p.m. and 7:00 a.m. IV-24 V. ALTERNATIVES TO THE PROPOSED ACTION A. No Project A discussion of retaining the status quo condition of a project site is required by CEQA Guidelines. No development of any type would leave the project area as an open field traversed by a small stream. There is a freshwater marsh and willow woodland associates with the stream course. Increased development with resultant increases in human activity on properties adjacent to the project site would have a marked effect on the subject property. A major housing development across the street is under construction. While difficult to quantify, the anticipated effect on the site is outlinedas follows: - Retention of a sizable open space area surrounded by urbanization. - Use of the area by local children as a play area, in effect a giant "vacant Lot". - Potential for erosion control problems; currently planned drainage and flood control facilities both above and below the area would have to be reevaluated to determine the effect on the project area. Stream channel downcutting and siltation are both likely to occur as a result of increased runoff from adjacent urbanization. - Loss of the remaining standing walls of the Ybarra adobe due to continued erosion and vandalism. - Public health and safety hazard resulting from lack of supervision and limitation of police access to the area; problems, in particular mosquitos, rats, mice and ground squirrels. - Continued degradation of the areas native wildlife as a result of the surrounding urbanization. B. Commercial/Industrial or Residential Use This alternative considers the use of the subject site for more intensive urban uses than those proposed. Because the site is located within the core area of the planned La Costa community, it would appear to have a development potential either residential use or support commercial and/or light industrial use. The implications of such development are outlined below: - Requirement for a major change in the approved La Costa Master Plan, including plan and zoning changes and land division. - Loss of City required open space/recreation area; additional land of comparable size in the local area would have to be found for another park to off-set the loss. V-i - There would be an increase on service and infrastructure requirements, as well as traffic. The magnitude of such increases would vary greatly with the actual use, although probably within the basic limits of proposed street and utility systems. - All facets of the sites' natural environment and historic resources would be destroyed. C. Park Design Alternatives The alternatives described in this subsection focus on modification to the range and intensity of recreation uses presented for the selected project described in the Project Description. Two such alternatives are discussed. Both were designed to be responsive to the need for additional active recreation areas, while at the same time maximizing the historic and natural factors associated with the site. The alternatives are conceptual only, and include only a preliminary analysis of grading. Alternative C-i. Maximize Historic and Natural Factors Alternative #C-1 seeks to preserve and enhance the natural aspects of the project site to the greatest extent possible, while providing active recreation areas. In addition, an active preservation program, including interpertative displays, of the sites' historic resources would be included. The Community Center, basketball courts and tennis courts would be retained. A generalized concept plan is presented as Figure 12. Specific aspects of this alternative are outlined as follows: - Re-design of the project to allow for retention of the stream bed as it now exists and inclusion of a 150 foot buffer zone along each side of the streams centerline. - Flow restriction measures upstream and siltation control features downstream would be needed to prevent erosion caused by increased runoff. - The Ybarra Adobe ruins, including the site of the barn, would be protected to the maximum extent possible. This would entail an enclosure around the ruins of the main house, and protective fencing. An interpretive display would also be included. V-2 At*11-10FAAa- F-4-1HIstoric Feature FIGURE 12 Alternative #1, Maximize Historic & Natural Features 'No Scale - Introduced plant species would be limited to the maximum extent possible. Native plants would be added to enhance the present vegetation features of the site. - Three of the five multi-use fields shown on the current park plan would be eliminate by this alternative. Shifting the park site to the east has the potential for adding an additional multi-use field. - This alternative also has the potential for adding a second ingress/egress point. The amount of parking would remain the same, but possibly could be decreased if not required as a result of the reduction in the number of playing fields. Alternative C-2. Retention of Stream Alignment /preservation of Main Historic Feature Alternative #C-2 is a plan concept which attempts to retain the stream channel in its current alignment and preserve the ruins of the Ybarra ranch house without the loss of any active recreation uses. The community center, basketball courts and tennis courts would all be retained by this alternative. A generalized concept plan of Alternative #C-2 is presented as Figure 13. Specific aspects of this alternative are outlined below: - The stream would be retained in its current alignment, although an option with this alternative would place a multi-use field in the western portion of the site, eliminating a portion of the southern section of the stream. This section of the park site contains the most disturbed portion of the wildlife habitat. Fill has been placed along Mission Estancia in the portion of the park site (see Figure 6). - The main Ybarra Ranch house ruin would be retained and protected, although the site of the barn would be graded. - Only one of the currently proposed multi-use fields would be lost by this alternative, and this field could potentially be located in the westerly portion of the site. - The parking area would be substantially altered. All of the parking would be in one area, and two ingress/egress points are proposed. - As with alternative #C-1 the westerly portion of the site could be traded for an area east of the site. This would allow for the potential inclusion of an additional playing field. V-4 / I / I I / L . 61 / t.

ANALYSIS OF LONG-TERN EFFECTS A. The Relationship Between Local Short-Term Uses of Man's Environment, and the Maintenance and Enhancement of Long-Term Productivity 1. Cumulative and Long-Term Effects The primary long-term effect of adopting the proposed Stagecoach Park Schematic Master Plan and subsequent construction of the park will be the commitment of the site for public park purposes. Development of the park does not pose long-term risks to health or safety, and does not utilize an area involved in the production of natural resources. Implementation activities related to the proposed park development will result in disruptive short-term impacts associated with construction activities. These impacts will be of minor consequence to the immediately adjacent properties. Several nearby residential and commercial projects have been approved by the City of Carlsbad, or are anticipated to be submitted in the forseeable future. Stagecoach Park and these projects are included in the La Costa Master Plan and are required to be in substantial conformance with the requirements of the Master Plan. The cumulative long-term effects of the proposed park and other related projects are: o Reduction of wildlife habitat; o Increase in traffic, which will impact streets in the vicinity of the park; o Minor increase in noise levels due to increases in traffic levels; and o Potential loss of historic resources. 2. Project Justification Adoption of the Stagecoach Park Schematic Master Plan and subsequent construction of-the park facilities will provide community park facilities for the southeast section of the La Costa community. The intent of the park plan provides for the preservation of the historic ruins located within the project boundaries and implements an action program of the Parks and Recreation Element. The City has a deficiency of playing fields for the current population. Recently the Parks and Recreation Commission has endorsed a set of standards for the number of fields based on population. Stagecoach Park will allow the City to reduce the deficiency in existing recreational facilities (A-7, B-7). VI-1 B. Significant Irreversible Changes Involved in the Proposed Project Development of the park, as currently proposed, would destroy the natural habitat associated with the stream which traverses the site and could adversely effect the remains of the Ybarra ranch house and barn. 1. Significant Unmitigated Effects A. Biology: The proposed project Alternative la will eliminate a majority of the wildlife uses and habitat now located on the site. 2. Adverse Impacts The following adverse impacts will result from the implementation of the proposed Stagecoach Park Master Plan, but they are not considered significant: A. Noise/Lighting: Impacts to adjacent residential areas can be reduced to a less than significant level through implementation of recommended mitigation measures. B. Drainage: Alteration of a natural drainage course with a potential for erosion during construction phases and increased runoff due to urbanization. C. Traffic: Potential adverse traffic condition at the park's entrance and lack of adequate parking during peak park use periods. D. Historic Resources: The preliminary grading plans indicate that the house ruins would be removed, even though the intent of the park Master Plan is to preserve the ruins. If the grading plans are revised, the significance of this impact could be reduced to a less than significant level. 3. Beneficial Impacts These impacts which will result from implementation of the project are: ° Provision of active and passive recreational facilities; and 0 Implementation of one of the City's responsibilities established in the La Costa Master Plan. 4. Environmental Effects Considered But Not Found To Be Significant The Environmental Checklist and Initial Study prepared for this EIR is included as Appendix A of this report. Those impacts considered in the Checklist and determined not to be potentially significant, and not addressed in this EIR, include: VI-2 a. Degradation of water quality; b. Depletion of natural resources; c. Creation of a public health hazard; d. Risk of explosion or release of hazardous substances; e. Change in the distribution or growth rate of the population; f. Housing; g. Air quality; h. Public services; and i. Energy and utilities. C. Growth-Inducing Impacts The future development of Stagecoach Park will not induce additional population or housing growth in the area. The facilities are planned as an integral part of the La Costa Master Plan. The park will provide recreational opportunities for current and future residents of the La Costa community. The scale of the planned facilities will attract few visitors from other areas. VI-3 VII. REFERENCE DOCUMENTS, PERSONS, AGENCIES AND ORGANIZATIONS CONSULTED, AND PREPARERS OF THE EIR A.

STATEMENT OF NON—SIGNIFICANT ENVIRONMENTAL EFFECTS If you have answered yes to one or more of the questions in Section Ibut you think the activity will have no significant environmental effects, inaicats your reason. D.Lvw; This project is part of the Parks and Recreation Element of the General Plan for community park development. The plan as submitted relocates an existing riparian area consisting of bull rushes, cattails, willows and eucalyptus trees to the -northern border of the park. The new channel will be constructed as to engineering specifications and replanted to re-establish the riparian area. The existing drain channel would be a safety and health hazard to the planned use of the park. This existing waterway will be required to accomodate a high volume of water during inclement weather and from upstream housing development, thus creating oncompatible uses. The necessity to develop and landscape the park to meet the need of the community outweighs the leaving of the riparian area in its original location. III.

DISCUSSION OF VIRO.\NTAL EVALUTION The City is requesting a conditional use permit for the constructi of a 28-acre community park in the southeastern portion of the city. Construction of the proposed park would require apprixi- mately 220,000 cubic yards of cut and 190,000 cubic yards of fill. The design of the proposed park would also impact .an exist riparian habitat. Due to the number of potential impactsinvolvec with this project staff believes that a focused Environmental Imp Report should be prepared. This EIR should discuss biology, archeology, land use compatibility, traffic,, soils, and drainage. .7- IV. DETERMINATION. (TO BE CC1'ffLETED BY 11 PLANNING DEPAR1iv!r) On the basis of this initial evaluation: - I find the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECJARATICt1 will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A conditional negative declaration will will be prepared. ._. I find the proposed project MAY have a significant effeci on the environment, and an EVIROMTAL IMPACT REPORT is required.

Lake Ave. (Suite 207) Pasadena, CA 91104 Dear Mr. Secord: Sorry to take so long to get back to you, but I felt the Stagecoach Park/Ybarra Ranch matter should be discussed formally with the Carlsbad Historical Society board and membership. This was done at our meeting of January 22. Although the Carlsbad Historical Society has no authority to approve or to veto city projects, the city does take our recommendations seriously and has required developers to change their plans to accommodate our suggestions. From the information we have gathered on the site we have made a number of observations: 1. The plans under consideration seem to be dominated by active playing fields, with some passive areas and a small designated historic site. 2. Cn viewing the site, we found the first area acproached to be the flatest, apparently a flood plain. On the plans it was designated a "passive area" and was generally unaltered. The plans also indicated that an important Eucalyptus tree and a prominent knoll were proposed to be destroyed in order to create flat Daying fields. 3. We also found interesting old adobe ruins, part of the Ybarra Rancho, which date back to the 1840's. These ruins overlook a meandering stream and recall memories of an earlier time when the site may have been a stop on the stagecoach route, atop which relied on the all-year stream for its water. Scattered remnants of barns and corrals and the hundred year-old tree reinforce the history of the site. Willows and the stream bed probably remain much as they did when the site was occupied. Behind the ruins a knoll rises, over which the stages may have arrived from the north. In our discussion of this matter, we could not help but consider the historical versus the recreational value of the site. 2. Maximizing either clearly compromises the other. The plan now seems to maximize active playing fields, at great expense and at great cost to the historical resources on the site. Of most historical importance is the relationship between the adobe ruins and the waterway, for this is probably why the building was located here. It is our strong recommendation that the ruins, the slope down to the creek (including the large Eucalyptus) and the existing watercourse should all be preserved as a historic/passive recreational environment. The flood plain and the upland knoll back to the proposed road could both be developed into active playing fields, parking lots, and recreational buildings without destroying the imprrtant historic elements. The Carlsbad Hist±cal Society would like to go on record as recommending the acquisition of the remaining pieces of the site and development of the park take place with these design objectives in mind. With all good wishes. Sincerely yours, k ey Armour President Carlsbad Historical Society APPENDIX C RESPONSES TO COMMENTS RESPONSE TO COMMENTS 1. Department of California, Department of Fish and Came dated April 8, 1985 The Park Master Plan is now being redesigned to allow retention of the streambed and to include siltation control measures. The City's landscape architect has been instructed to incorporate the existing riparian area into the Master Plan for the park as well as maintain the area devoted to playing fields to the extent possible to provide the active recreation area much needed by the little league, soccer league, and other groups within the City. The City Parks Department is in communication with Department representatives and has scheduled site visits to discuss recommendations of the Department and establish an understanding of modifications to be made to the project. 2. San Dieguito Union High School District dated April 1, 1985 Comment noted. 3. Carlsbad Historical Society (undated) The retention of the relationship between the stage-stop and the stream will remain under the modified plan presently being completed by the City Parks Department. (See response to Fish and Game comments above.) This modified plan preserves the stage-stop and the large Eucalyptus trees contained on the site.

Observations: We viewed plans dominated by active playing fields, with some passive areas and a small designated historic site. We visited the site. The site was quite surprising after viewing the plans. The first area approached was the fla,,sçnd generally least interesting. Apparently a flood plain,,it Jas designated as a "passive area", and generally unaltered. On the other hand, a charming riparian envircunent, an important large Eucalyptus tree and a prominent knoll were?2e destroyed in order to create flat playing fields. Interesting adobe ruins which overlook the meander iiig stream hearken back memories of earlier times when the ruins were a stagecoach stop which. relied on the all-year stream for its water. Scattered remnants of barns and corrals, and the hundred year-old tree reinforce the history of the site. Willows and the stream bed must remain much. as they did when the site was occupied. Behind the ruins, a knoll rises, over which the stages probably arrived from the north. We were asked whether we thought the historicity of the site would be altered if the ruins were relocated. Comments.: One cannot help but want to consider the historical versus recreational value of this site. Maximizing either clearly compromises the other. The plan as now layed-out attempts to maximize active playing fields, at great monetary expense, and great cost to the historical resources on the site. Of most historical importance is probably the relationship between the stage-stop (ruins) and the waterway, fd'r, this is surely why the building was located here. The ruins, the slope down to the creek (including the large Eucalyptus) and the existing watercourse should be preserved as an historic/passive recreational environment. The flood plain, and the upland knoll back to the proposed road could both be developed into active playing fields, parking lots and recreational buildings without destroying the important historic elements. We recommend acquisition of the remaining pieces of the site and development of the park take place with these design parameters in mind. Submitted by: Kip NcBane 8 photos attached
