One of the requirements of the Shoreline Master Program (SMP) Update process is to prepare a Cumulative Impact Analysis (CIA). The purpose of the CIA is to ensure that SMP updates include shoreline policies and regulations that will achieve no net loss of shoreline ecological functions, as the SMP is implemented over time.
ESA Adolfson has prepared a CIA, which describes anticipated shoreline development within the City’s jurisdiction and assesses the cumulative impacts of such development on shoreline ecological functions over the long term. The CIA is intended to inform decisions about where to apply regulations to most effectively protect shoreline ecological functions. According to WAC 173-26-186(8)(d):
“Local master programs shall evaluate and consider cumulative impacts of reasonably foreseeable future development on shoreline ecological functions and other shoreline functions fostered by the policy goals of the act. To ensure no net loss of ecological functions and protection of other shoreline functions and/or uses, master programs shall contain policies, programs, and regulations that address adverse cumulative impacts and fairly allocate the burden of addressing cumulative impacts among development opportunities. Evaluation of such cumulative impacts should consider: (i) Current circumstances affecting the shore lines and relevant natural processes; (ii) Reasonably foreseeable future development and use of the shoreline; and (iii) Beneficial effects of any established regulatory programs under other local, state, and federal laws. It is recognized that methods of determining reasonably foreseeable future development may vary according to local circumstances, including demographic and economic characteristics and the nature and extent of local shorelines.”
