c. PRZ-13. Discussion and Inuut on Residential Green Buildine Measures for a Future Ordinance Ms. Nerland summazized the staff report. She noted that at this time, there is no U.S. Green Building Council rating system for residential construction and that it was between one to two yeazs into the future. On September 10, 2003, the Alameda County Waste Management Authority (ACWMA) made a presentation to the Planning Commission regarding its new Green Points rating system for single-family residential projects. The Planning Commission believed that single-family residential buildings in PUD zoning districts should be required to meet the 50-point threshold and be encouraged to strive for the 60-point threshold, with five-point incremental increases each year. City Council then directed staff to re-examine the issue with respect to an ordinance versus imposition of an ad hoc condition of approval In April, 2004, following the staff report, the City Council directed staff to proceed with drafting an ordinance after seeking input from a number of stakeholders in the process, including the development community, the Chamber of Commerce, the Economic Vitality Committee, the Pleasanton Energy Committee, the Housing Commission, and the Planning Commission. Ms. Nerland summarized the five issues that were asked of each body: L Is ACWMA's "New Home Construction Green Building Guidelines" the appropriate rating system to use for single-family homes? Ms. Nerland noted that the Housing Commission and Chamber of Commerce believed that this should not be an ordinance, but should be a mazket-driven approach with incentives. The ordinance proponents believed that the certainty provided by an ordinance would be desirable to the development community. Staff believes that the issue of whether to address societal issues by an incentive, market-driven approach versus government regulation is not new to green building or to the City. The decision would ultimately be made by the City Council. She also noted that the menu approach of the ACWMA guidelines does allow developers to pick items based on the mazket. 2. If the ACWMA rating system is used for single-family residences, are the proposed 50- and 60-point thresholds appropriate? Should any required point level increase on a yeazly basis as initially recommended? In general, there was not support for increasing the threshold by five points every year without some kind of review. PLANNING COMMISSION MINUTES July 14, 2004 Page 8 of 24
