Site History and Details
It’s important to know the history of this site before we talk about its transformation into new homes and neighborhood serving retail. Below are a few details about the property over the course of the last 100 years:
- A railroad spur, or short segment of track, once bisected the property running north-to-south.
- Safeway Stores, Inc. operated a butter and cream plant and meat distribution plant.
- Safeway, as well as The Hills Brothers/Nestle Company, each operated a coffee depot and offices on the property.
- In 1997, Mackenzie Warehouse, an automotive parts warehouse was established.
- Coach 21, a bus transportation business, arrived in 1985.
- Along Carolina Street, homes were developed as early as 1900.
- By 1914, the residences had been removed and the property was vacant.
- The on-site building along Carolina Street was constructed in 1978.
The land at 1601 Mariposa has had many uses and in order to prepare the property for residential use, Related must address the environmental issues caused by years of commercial and industrial operations. As proposed, the remediation and removal of the materials will be managed and monitored by numerous local and state agencies, including the San Francisco Department of Public Health (DPH), the Bay Area Air Quality Management District (BAAQMD) and the California Department of Toxic Substances Control (DTSC). It is the DTSC that will approve and oversee a remediation plan (also called a “Response Plan”) for the site.
Related California and DTSC are in the midst of finalizing a clean-up agreement for implementation of remediation and mitigation of the environmental concerns. The plan will employ standard measures that have been used regularly in residential development with similar conditions in San Francisco and other parts of the state. Once the remediation and mitigation work is complete, the land can be adapted for housing, parks, and stores.
