PROJECT PROPOSAL:
The proposed project involves the final remediation of the Ascon landfill and includes the following entitlement requests:
Coastal Development Permit No. 16-016: To implement the final remedial action plan for the site with grading involving more than 25,000 cubic yards of import/export within the Coastal Zone.
Conditional Use Permit No. 16-034: To permit: 1) a 6 ft. tall aluminum fence with 6.5 ft. tall pilasters at a 3 inch front setback along Hamilton Ave. and Magnolia St. instead of a minimum 15 ft. setback; and 2) gated access to the site.
The Ascon Landfill Site is a vacant 38-acre property at the southwest corner of Magnolia Street and Hamilton Avenue. The site operated as a waste disposal facility from 1938 through 1984. Since 1984, waste materials have not been accepted and the site has remained a closed landfill facility. The Department of Toxic Substances Control (DTSC) is the lead agency overseeing the remediation of the site. DTSC certified the Environmental Impact Report (EIR) and approved the Remedial Action Plan (RAP) for Ascon landfill in June 2015. The final remediation for the site includes excavation and offsite disposal of waste, grading of the site, construction of an engineered protective cap over the site with a vapor collection system, a perimeter maintenance road, and two stormwater detention basins.
The applicant is requesting the reduced front setback for the decorative aluminum fence because providing the required 15 ft. setback would raise the vegetated cap and the southwest portion of the cap cannot be raised further due to geotechnical stability concerns. The additional setback would also impact the access road located behind the fence that is needed for long-term operation and maintenance of the cap. In addition to the decorative aluminum fence proposed along the street frontages, a 6 ft. tall vinyl coated chain link fence is proposed along the majority of the south and west property lines except where existing industrial buildings and fencing adjoin the western boundary of the site. The site currently has gated access along both streets.
The project narrative (Attachment No. 4) provides a brief background of the previous activities at the Ascon landfill and describes the main components of the final remediation, haul route, site access, import/export volumes, and approximate timeline of at least 18 months to completion. The final remediation work will be conducted between the hours of 7:00 a.m. and 6:00 p.m. Monday through Saturday, with employee arrival, safety meetings, and workday preparations (e.g. equipment inspections) beginning as early as 6:00 a.m.
Upon completion of the final remediation, the site will have a sloping drought-tolerant vegetated cap that rises gradually from the Magnolia and Hamilton street frontages to a maximum height of approximately 32 feet at the southwest (interior) corner of the site.
CEQA:
The project is covered under the EIR for the ASCON Landfill RAP (State Clearinghouse No. 2013041010) certified by the Department of Toxic Substances Control in June 2015.
PLANNING ISSUES:
⁻ Compatibility of the proposed final remedial action plan and fence with the surrounding area.
