The numbered responses correspond with the numbered paragraphs on your letter. 1. No comment required. 2. No comment required. 3. The State Lands Commission and the City of Carlsbad will be involved in the review and approval of the desilt basin. The City of Carlsbad will issue the grading permit after all resource agency reviews and applicable mitigation measures have been secured. In addition, the project underwent the standard public review process for a project in the coastal zone. This includes State Clearinghouse (SCH) review which distributes the environmental review to all potentially affected resource agencies (SCH #94051035). 4. The basin's design proposed with this master tentative map application has been made available to Mr. Taschner. The specific design will be completed as part of the final map approval. It is not typical to approve a specific design (for a facility like this) at the tentative map stage. Final designs result from detailed plan check efforts that follow, and must be in conformance with, previous tentative map approvals made by the City Council and/or Planning Commission. The environmental impacts of the final design can not exceed those assessed with the tentative map approval. In addition, there has been a thorough analysis of east side and west side (of the railroad tracks) alternative drainage alignments. The alignment submitted with this master tentative map represents a worst case scenario from an environmental standpoint for a westerly drainage system. Although the proposed basin can be fully mitigated as outlined in the Mitigated Negative Declaration, it will likely be replaced by another basin as the result of a re-design intended to eliminate the assessed impacts. This re-design is part of the final design effort which will undergo City and resource agency review. 5. The discharge of drainage at this location has been considered during the review of the former educational master plan project as well as the on-going Batiquitos Lagoon Enhancement Plan. No negative impacts have been identified. 6. The proposal to construct needed underground piping along non-constrained roads and railroad rights of way does not need close environmental review prior to final design for an area that had previously received approvals for development and infrastructure construction. 2O75 Las Palmas Drive • Carlsbad, California 92OO9-1576 • (619) 438-1161 POINSETTIA SHORES MASTER TENTATIVE MAP CT 94-01/HDP 94-03 - LOU TASCHNER JUNE 28, 1994 PAGE 2 _ ___ The involvement of resource agencies will prevent the approval and construction of any basin in delineated wetland areas. The intent of the biological report was to determine the environmentally preferred drainage alignment: east or west of the railroad tracks. The impacts to sensitive lagoon and wetland areas associated with the demolition/expansion of the existing east side basin led to the conclusion that the west side basin was preferred since less biological impacts would be involved. 7. As part of concurrent processing and plan checking efforts by the applicant, a re-design is being finalized which will either remove or greatly reduce the impacts to the recent coastal sage re-growth. Either through mitigation, a re-design, or a combination of the two, no biological impacts will occur. 8. The applicant has complied with the requirement to assess drainage alignment alternatives in coordination with the City in processing the master tentative map application. The proposed alignment, accounting for minor re-design considerations, is the preferred alignment from an engineering, environmental and cost effective standpoint; and it is consistent with the City's Master Drainage Plan and the facility requirements of Zone 9. 9. The alignment and cost estimate attached to the letter overlooks (1) the difficult depths at which the pipeline will need to be constructed, (2) the modifications and additional biological impacts to the existing basin (as documented in the project's biological assessment report), and (3) the overall needs of the Master Drainage Plan (including the area on the west side of the railroad tracks) and is a departure from the Zone 9 Local Facilities Management Plan. In summary, the environmental review associated with the master tentative map is adequate for a tentative map approval. Final design can not result in additional or more significant environmental impacts. All applicable resource agency reviews and approvals are still required prior to final map approval. The comparison of impacts between an east side and west side basin concluded that the westerly alignment is preferred. The Planning Commission hearing date for this project is tentatively scheduled for July 6, 1994. I can be reached at (619) 438-1161 extension 4441 if you need to contact me.
