The project involves approval of a Removal Action Workplan (RAW) for the 2330 Monroe Street Affordable Housing Project (Site). DTSC is overseeing cleanup at the Site under a Standard Voluntary Agreement (HSA-FY19/20-122) with Freebird Development Company. The purpose of the RAW is to reduce the potential risk to human health and the environment from the contaminants of concern (COC) which include lead, arsenic, and pesticide; 4,4’-DDE in soil.
As described and discussed in the RAW, a cap is proposed as the remedy to prevent exposures between Site soils and future on-Site residents. The cap consists of the following elements which are identified in the approved design of the affordable multifamily residential project:
• Building foundations;
• Other hardscape including driveways, parking lots, sidewalks, patios, and other surfaces that prevent direct contact with Site soils; and
• At least 2 feet of suitable soil or landscaping material placed above a marker fabric.
DTSC utilized information and analysis in the Mitigated Negative Declaration (MND) for the 2330 Monroe Street Affordable Housing to support a final determination about the type of environmental document required to be prepared for the proposed 2330 Monroe Street Affordable Housing Project Removal Action Workplan as provided by Sections 15162, 15163, and 15164 of the CEQA Guidelines. Specifically, the MND analyzed potential impacts related to contaminated soils in Section 5.9 (Hazards and Hazardous Materials) and potential impacts related to grading and construction in Section 5.3 (Air Quality), Section 5.4 (Biological Resources), Section 5.5 (Cultural Resources), Section 5.7 (Geology and Soils), Section 5.13 (Noise), and Section 5.17 (Transportation/Traffic).
