I PLAN SUMMARY The overall objective of the Tiscornia Estate Specific Plan and EIR is to provide a master program to guide and facilitate the development of the designated 12.2-acre Tiscornia Estate area in Point Richmond. The plan recognizes the unique characte f thio r s sectio f Richmonno respondd dcity'an e neighborhood'd th so an st s concerns for promotiong quality development of the planning area. The specific plan has been prepared in a manner consistent with the requirements of State Plannin d Conservatioan g n Law, Title VII, Articl , eSectio8 n 64540e plaTh n . includes: specifiA • circulatiod c an lane dus n progra areae th r ;mfo • A set of detailed design and development standards for the area; f associateo t se A • d capital improvement requirement sequencesd san ; • A description of suggested cost responsibilities; and descriptioA • f potentiano l environmental impacts associated with development under the plan.

Existing lot lines and street right-of-way lines within the undeveloped areas will be abandoned, and all new development will occur on reconfigured lots with a minimum area of 5,000 square feet. Development is proposed to be gener- ally located around the perimeter of the planning area, while much of the central portio site th e f wiln o maintaine e b l opes da n unitsspacew majorite ne Th e . th f yo have been located on the lower elevations where visual and environmental sensi- tivit generalls i y y lower, and, where previous developmen occurreds ha t priA . - mary^criterio e locatioth n i n f developmenno e preservatiotth sites e wa s th f no planning area's high visua oped an ln space values, includin froy gba m e viewth f so existing residences, view t fro sitesitse ou e viewmd th th e an ,f froso m surrounding areas.
