MOUNTAIN HOUSE SPECIFIC PLAN 6 acres in area. 13oth of the preserved wetlands and adjacent buffer zones are designated as Open 5pacelResource Conservation on Figure 3.1:SPII Land Use. Within the proposed Mountain House Creek corridor,wetlands will be established to offset any loss of wetlands due to construction of the muff-u1 A norrldor. The creek corridor is comprlsed of excavated eharinels that include emergent marsh,seasonal wetlands and riparian scrub wetlands In the lower elevations. A mid-level terrace includes scattered Water quality basins that function as wetlands as well as no woodland and grassland savanna# habitats bordering the lower level ripadan wetlands. An upper terrace borders the mid-level terrace,and includes pedestrian paths within native Oak woodland and grassland habitats area. The Mountain House Creek corridor ranges In wldth from 204 feet to approximately 604 fleet. North of Byron Road,the corridor averages approximately 250 feet in width. Figure 7.11a:Dry Creek Open Space inustrates typical Cross-sections for Dry Creek. The Jurisdictional ditch downstream of the Dry Creek wetlands well be left undisturbed_ The capacily of the ditch maybe expanded by adding engineered fill outside of the jurisdictional area and above the ordinary high water mark,in order to accommodate 1 et} year storm flaws from off site soUrceB. No nn-site stprmwater will be discharged into the Dry Creek wetlands or its downstream ditch. A pedestrian trail may be allowed within the expanded ditch corridor provided it does riot result in disturbar oe of the jurisdictional area SPh Implementation Measures I. _Watlands Mitigation. Wetlands mitigation shall provide for creation of wetlands to replace those which would he las# if any. Mltigatloo, If required by the Clean Water Art,shall occur within the Mountain House and Dry Creek corridors. All mitigation will he as required by the provisions of the Clean Water Act 2. Buffering_ Whore preserved wetlands provide valuable habitat to wildlife, protective fencing,screening or buffers shall be provided where necessary to ml nimixe disruption of habitat areas. The type of protection will vary doppoding an the type and function of the wetland,the adjolning land use and the terrain. 3. MHGSD�RungOFREIEKAFEIFRORta.

Any fencing that is located within the drainage fac]Iltles shall be designed to prevent debris accumulation or otherwlse impact water surface elevations.
