Vantage to Pomona Heights Chapter 3 230 kV Transmission Line Project FEIS Affected Environment PAGE 3-287 must be removed from state-owned aquatic lands. NNR‐8 proposes to cross state-owned aquatic land and may require a ROE. Additionally, as part of the ROE, potential encroachment on the littoral (area of a sea, lake, or river located close to the shore) and near shore environment may impact aquatic species and associated habitat. These impacts may require Habitat Stewardship Review by the DNR and mitigation measures as part of the conditions of the temporary agreement. 3.14.3.3 Local Jurisdiction (County/City) Shoreline Development/Shoreline Management Act In Washington, the Coastal Zone Management Act is implemented through the SMA. The SMA regulates most shorelines of the state including marine waters, streams and rivers (with a mean annual flow of 20 cubic feet per second or more), lakes and reservoirs, or water areas of the state (larger than 20 acres) associated wetlands and portions of the flood plain. The SMA regulates wetlands with 200 feet of shoreline water bodies and wetlands associated with these water bodies. The SMA is implemented through a permit program for activities in and on the shorelines of the state. Permits are issued by local governments. For the proposed Project, the transmission line structures located with 200 feet of the shoreline for a crossing of the Columbia River by Route Segment 3b below the Wanapum Dam in Kittitas and Grant counties, Route Segment 3c below the Priest Rapids Dam in Benton and Grant counties, or Route Segment NNR-8 below the Wanapum Dam in Kittitas and Grant counties would require a Shoreline Substantial Development Permit. The permits are issued by the counties if permit applications comply with the local shoreline master program for the county and the policies and provisions of the SMA. The WDOE has primary responsibility to review issued permits for compliance with the shoreline master program. Most developments that meet a specific dollar threshold are considered substantial developments and require a Substantial Development Permit. Under certain circumstances, local governments can allow deviations from shoreline master program requirements through variance or a Conditional Use Permit. Critical Areas Ordinance The Washington State Growth Management Act identifies five Critical Areas in each Washington state county in accordance with RCW 36.70A.170. Critical areas include the following areas and ecosystems: a) wetlands; b) areas with a critical recharging effect on aquifers used for potable water; c) fish and wildlife habitat conservation areas; d) frequently flooded areas; and e) geologically hazardous areas. Counties that are covered under the Growth Management Act are required to protect Critical Areas (Washington State Department of Community, Trade and Economic Development 2003). Local Critical Areas In general, Benton, Grant, Kittitas, and Yakima counties identify the following as local critical areas: wetlands; critical aquifer recharge areas, and frequently flooded areas. These resources are addressed in Sections 3.14.2.1 – Wetlands, 3.14.2.2 – Critical Aquifer Recharge Areas, and 3.14.2.1 – Floodplains of this document, respectively. Floodplain Permit If a project is located in a mapped 100-year floodplain, the local government requires that a permit be obtained prior to development. Proposed projects are reviewed and conditions imposed on any permits issued to reduce the potential for damage from floodwater. Permits are required for any development in the floodplain.
