HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR CITY OF SANTA ANA 7. Alternatives to the Proposed Project 7.4.6 Hazards and Hazardous Materials Past and present uses and activities within the project area have known or suspected contamination of soils. Development and redevelopment in accordance with the NHSP would result in similar impacts to health and safety impact related to the presence of known or suspected on site contamination. Future development has the potential to be exposed to suspected sites, and demolition activities may expose construction workers to asbestos containing materials or lead based paints. This alternative would result in the same impacts related to hazards and hazardous materials as the proposed project. 7.4.7 Hydrology and Water Quality The project area is currently developed. Development and redevelopment in accordance with the NHSP would result in a similar amount of impervious surfaces as the proposed project. No changes to the volume or velocity of stormwater would occur because the project area is built out and the area of impervious surfaces is not expected to change. Short -term construction related and long -term water quality would be similar to the proposed project since future projects under this alternative would be required to comply with the Construction General Permit, requiring implementation of a Storm Water Pollution Prevention Plan (SWPPP for projects one acre in size or more, and prepare a Water Quality Management Plan for all for all projects that meet the thresholds. Therefore, this alternative would be less than significant with mitigation and have similar hydrology and water quality impacts as the proposed project 7.4.8 Land Use and Planning Unlike the proposed project, this alternative would not require a zoning ordinance amendment, a zone change, or a General Plan amendment. However, this alternative would not meet the goals of the housing element to the same degree because this alternative would not result in an increase in affordable housing allowed on site. In addition, this alternative would not support the Iand Use Element Policy 2.4 to the same degree as the project because it would not result in enhancements to the existing sidewalks. This alternative would not provide a catalyst for revitalizing the corridor. As a result, impacts related to land use would greater, but less than significant. Under this alternative, grading and construction noise would be similar to the proposed project since development would continue to be allowed in accordance with the NHSP. Stationary noise sources associated with new commercial development would have the potential to increase noise levels at adjacent properties, similar to the proposed project. Operational traffic related noise would be less since this alternative would generate less vehicle trips. Overall, noise impacts would be less than the proposed project. 7.4.10 Population and Housing Population and housing impacts would be increased by this alternative. This alternative would result in approximately 10,000 employees due to the increase in approximately 4.9 million square feet of commercial uses. This alternative would allow 320 residential units. As a result, the jobs - housing balance for the project Page 76 PlaceWorkr
