HELIX Environmental Planning (HELIX) prepared air quality and greenhouse gas emissions technical reports and a waste management plan for a mixed-use development project on Iowa Street in the North Park area of the City of San Diego. The project proposed a Process Three Site Development Permit, Conditional Use Permit, and Vesting Tentative Map to allow construction of a five-story, mixed-use affordable senior housing development, consisting of 100 one-bedroom and 20 two-bedroom rental units; 3,666-SF of street level retail and commercial space; common areas that included a community center, leasing offices, laundry facilities, community gathering and landscaped areas, and support facilities; and a ground-level parking garage with 113 spaces. In preparing the site for construction, the project required demolition of the existing 20,753-SF commercial building, parking lot, curbs, and sidewalks; vegetation removal; and site grading. Grading of the parking garage required export of approximately 3,478 tons of soil material. In the waste management plan, HELIX identified the quantity of solid waste that would be generated by the project and measures to reduce the potential impacts associated with management of such waste, pursuant to the City of San Diego’s waste reduction ordinances and the waste diversion goals established in State AB 341. The project would exceed the 75 percent solid waste diversion rate goal for waste produced during demolition and construction phases by achieving 92 percent and 79 percent diversion rates, respectively, and would implement sustainability and efficiency measures to further reduce waste generated during operations.
