COUNCIL AGENDA STATEMENT Item 5 ITEM TITLE: Resolution Id7'6~ Certifying environmental Long Canyon Estates) Meeting Date 5/26/81 impact report EIR-79-2 (Bonita SUBMITTED BY: Director of Planning~ (4/5ths Vote: Yes No~) P.. BACKGROUND 1. The Environmental Impact Report for this project was certified by the Planning Commission on February 28, 1979. The document has not been certified by the City Council because of Council's indication in 1979 that development of large projects easterly of Otay Lakes Road which are tributary to East "H" Street were premature. ? The applicant has now submitted a Sectional P1Jnning Area plan for the overall development and a tentative subdivision map for Phase I of the project for consideration by the City. The plan involves several revisions to the plan presented in the Environ'- mental Impact Report. 3. On March 19, 1981 the Environmental Review Committee held a public hearing to determine the adequacy of EIR-79-2 due to the project revisions and possible chanqes in circumstances during the two year period after preparation of the document. The Committee concluded that the project revisions would not result in any significant environmental impact which was not previously evaluated in EIR-79-2, and recommended certification of the EIR. 4. On April 22, 1981 the Planning Commission recertified the EIR. B. RECOMMENDATION Certify that EIR-79-2 has been prepared in accordance with CEQA, the State EIR gui~elines and the environmental review procedures of the City of Chula Vista. C. PROJECT REVISIONS 1. The phasing of the project has been changed as follows: 1979 Phase No. 1981 revised Phase No. I I II III III IV IV II V V VI VI The proposed changes in phasing are due to the development of the Bonita Haciendas subdivision to the north of Bonita Vista High School with the related extension of streets and utilities which provide access. 2. Avenue. was also The project as previously proposed involved access to Acacia Avenue or Tim That access has been deleted in the applicant's revised plan. Eventual access proposed via "s" Stre"et to a future subdivision to the nOr'thwest of the project.

Therefore, the applicant did not show this connection on the Sectional Planning Area plan. However, the final map has not been recorded on the County subdivision and the connection is highly desirable from an emergency vehicle circulation standpoint. Therefore, a condition of approval has been established to require the connection. 3. The subdivision design in the vicinity of "Q" street and the SDG&E easement has been modified so that a large portion of the unique stand of Cleveland Sage is retained. 4. The proposed 17 acre equestrian center has been deleted and replaced with 24 dwelling units as a part of Phase II of the project. The elementary school/park site has been redesigned and a water tank for the Otay ~unicipal Water District h~s been added. The overall result has been the addition of about 41 dwelling units. D. ANALYSIS 1 . Geology. A detailed geological report was prepared on the first three phases of the project as delineated in the EIR. The revised plan changes the phasing of the project anrl, therefore, it will be necessary to prepare a more detailed teological report on phases II and V prior to submission of a tentative subdivision map for those phases. 2. Soil s . The previously prepared EIR delineates onsite soil conditions which could result in substantial erosion and downstream siltation; also, some onsite soils are hi<;bly eX0ansive or compressible. The recommendations in the EIR, including downstream siltation basins, are adequate to mitigate any potential impact. The modifications to the project do not involve major changes in the grading of the project area, therefore, the previous analysis is adequate. 3. Dra i nage. The EIR identified a potentially significant impact due to a small increase in nm,.off and the inadequacy of downs tream fac il i ti es. The project proponent proposes to install retention basins which will reduce the peak downstream water flow and act as sedimentation basins. The maintenance and operation of these facilities would be the responsibility of an open space maintenance district. ~.. Land Form. The project revisions do not involve any major alteration in the preliminary gradino concept and, therefore, no reevaluation is necessary. 5. Aesthetics. The aesthetic impact of the project was primarily related to the land form altera- tion and removal of vegetation. The grading concept'has not been changed and, then!- fore, the aesthetic impact has not changed. continued \, /02-/6% . . Page 3, Item. 5 f.1eeting Date 5/26/81 6. Schools. The elementary schools serving the project area are shown to be near capacity in the final EIR and it was estimated that the project would generate about 500 elementary school students, roughly the equivalent of an elementary school. These conditions have not changed and the previous analysis is adequate. The secondary schools serving the project area .have experienced a decline in enrollment since certification of the final EIR; therefore, the project will have a less severe impact than that which is portrayed in the final EIR. Building permits for any portion of the development will not be issued until such time as the school districts have informed the City that they can adequately serve the development. 7. Sewer. The final EIR identified a dispute regarding the capacity of downstream sewer lines due to a very flat grade. It is unclear how Phase V of the project would be provided with sewer service. Previously this area would have been served through offsite sewer line extensions within streets. Because the street extensions are no longer proposed, Phase V may be connected to the Bonita Ridge sewer line which has questionable capacity. A solution will have to be reached prior to approval of the tentative map for Phase V. 8. Archeology. Subsequent to the certification of the final EIR, the recommended mitigation measures were implemented, so there will be no significant impact on cultural resources. 9. Biology. The modifications of the project design at "Q" street and the mitigated any significant impact on the stand of Cleveland Sage. seedling culture of other onsite sensitive species can be carried implementation to avoid~ any significant impact. SDG&E easement have Transplantation. and out during project 10. Traffic and Access. The deletion of access to Tim or Acacia Avenues and the access point near the northwest corner of the project would result in the shifting of about 1,740 trips to other access points. A traffic study was prepared on the changes that are currently proposed in the circulation portion of the plan. It was the conclusion of that report that offsite improvements necessary to miti ga te some of the si gnifi cant impacts WQul d become more critical but impacts would be mitigable. by the City Council oT Chula Vista, Ca!ifornia , ., Dated J;.;J. b -PI /o</6t
