Related California's proposed massive rental complex on 1601 Mariposa Street is too big for Potrero Hill


It is important to expand housing and grow Potrero Hill responsibly.

RELATED CALIFORNIA PLANS TO BUILD A 4-STORY, 40 FT. TALL, AND 320-UNIT RENTAL COMPLEX AT 1601 MARIPOSA STREET, ON THE BLOCK THAT RUNS ALONG 18TH STREET BETWEEN CAROLINA  AND ARKANSAS STREETS. SOME PARTS OF THE BUILDING WILL BE 5 STORIES HIGH AND EXCEED 40 FT. THIS MASSIVE COMPLEX COULD BRING WELL OVER 700 NEW RESIDENTS TO POTRERO HILL. THE PROPOSED PROJECT INCLUDES ONLY 272 PARKING PLACES DESPITE TRAFFIC STUDIES SHOWING DEMAND FOR 465. AS PROPOSED, 1601 MARIPOSA IS CONSDERABLY LARGER AND DENSER THAN ANYTHING IN OUR NEIGHBORHOOD.

THE DEVELOPER PLANS TO LIMIT OPEN SPACE AND BUILD A MERE 16 FEET AWAY FROM LIVE OAK SCHOOL’S CLASSROOM WINDOWS. THE BUILDING WILL TOWER OVER THE SCHOOL’S COURTYARD PLAY AREA, SHADOWING IT FOR MUCH OF THE SCHOOL YEAR. THE BUILDING WILL ALSO CAST SHADOWS ON JACKSON PARK WHERE THE COMMUNITY GARDENS ARE LOCATED.

ALONG WITH OTHER PROJECTS IN THE PIPELINE, 1601 MARIPOSA WILL HAVE A SIGNIFICANT IMPACT ON TRAFFIC, PARKING AND TRANSIT. LARGE INCREASES IN THE NUMBER OF RESIDENTS WILL OVERBURDEN OUR ALREADY LIMITED OPEN SPACES, OUR INCREASINGLY CROWDED STREETS AND OUTDATED INFRASTRUCTURE.

ENVIRONMENTAL STUDIES INDICATE THAT THE SITE CONTAINS ASBESTOS, AND UNDERGROUND OIL TANKS THAT HAVE LEAKED AND CONTAMINATED THE SOIL AND GROUNDWATER WITH BENZENE AT LEVELS THAT ARE WELL ABOVE THE RISK LEVEL FOR CANCER. THESE CONDITIONS POSE HEALTH HAZARDS DURING CONSTRUCTION TO SURROUNDING RESIDENTS, TO NEIGHBORING HIGH SCHOOLS, TO LIVE OAK SCHOOL AND TO THE CHILDREN WHO PLAY IN JACKSON PLAYGROUND.

THE EASTERN NEIGHBORHOODS PLAN INCLUDED AN ENVIRONMENTAL IMPACT REPORT (EIR), THAT DIDN’T CONSIDER THE PROJECT’S PECULIAR AND SIGNIFICANT IMPACTS AT THIS SITE, AND DIDN’T CONSIDER THE CUMULATIVE IMPACT OF MULTIPLE PROJECTS IN THE NEIGHBORHOOD. THE SF PLANNING DEPARTMENT SHOULD NOT GRANT A COMMUNITY PLAN EXEMPTION AND REQUIRE A FULL EIR BEFORE ANY APPROVALS ARE GRANTED.
