Construction and Demolition Regulations The City of Pleasanton's current C &D (construction and demolition) regulations require 50% diversion of solid waste and recyclables (and 90% diversion for concrete). This standard is consistent with CALGreen's basic requirements for both residential and non- residential projects. The proposed local amendment specifies that the elevated Tier 1 percentages would not be imposed on projects otherwise required to meet Tier 1 standards, and effectively retains the City's current C &D requirements (see proposed PMC 20.26.30.A - which references PMC Chapter 9.21). There is one component of CALGreen where the required basic measure is more stringent than the City's current C &D regulation, i.e., with regard to soil and green debris. Non - residential projects are required to reuse or recycle 100% of soil and green debris, where the City's C &D regulations do not address soil or green debris. Therefore, the local amendment maintains the City's existing C &D regulations for the solid waste and recyclable materials, but adopts the State mandated minimums standards for soil and green debris. Additionally, the proposed amendments stipulate that all other projects (those below the $125K C &D threshold) must meet CALGreen's mandatory basic construction waste provisions. These amendments retain the City's existing requirements for C &D, while adhering to the mandatory State -wide minimums. Alternative Amendment Option While the amendments outlined above are supported by the various boards and commissions that reviewed the matter (Committee on Energy and Environment, Economic Vitality Commission, and the Planning Commission), the City Council may wish to consider other options. The only significant concerns with staff's proposed approach have come from StopWaste.Org, who has expressed concern about the absence of verification procedures for some of the green measures called for in Tier 1. To address this concern, the following options are also available to the Council: 1. Continue to use the Build It Green rating system for residential projects and simultaneously enforce the State mandated requirements of CALGreen. Commercial and Civic projects would be subject to CALGreen Tier 110 in lieu of our current requirements based on LEED, as recommended by staff; or 2. Continue to use the Build It Green rating system for residential projects and simultaneously enforce the State mandated requirements of CALGreen for a period of six (6) months to allow the State to provide the additional guidance that StopWaste.Org feels is currently lacking. Under Alternative 1 above, applicants would have to be versed in both systems (CALGreen and BIG) to ensure that they are not over or under designing their projects. Under Alternative 2, the same challenges would remain, but they would only exist for a period of six (6) months. 10 Tier 1 measures are for the specified , :overed projects, while CALGreen basic measures would apply to all other projects.
