Murrieta Creek Multi-Use Trail (Lake or Streambed Alteration Agreement No. EPIMS-RIV-43632-R6)

Murrieta Creek Multi-Use Trail (Lake or Streambed Alteration Agreement No. EPIMS-RIV-43632-R6)

The California Department of Fish and Wildlife (CDFW) has executed and issued a Lake and Streambed Alteration Agreement (EPIMS-RIV-43632-R6), pursuant to Fish and Game Code section 1602, to the project Applicant, City of Lake Elsinore, as represented by Remon Habib. The Project is limited to construction of a multi-use trail that will be a 10-foot-wide paved trail within the Lake Elsinore Back Basin. Split rail fencing will be mounted on either side of the trail with a 2-foot-wide decomposed granite or native landscape recovery zone between the fence and the asphalt path, for a total permanent impact width of 20 feet. The proposed Project will also include a single Arizona crossing and a span bridge and the replacement and extension of a pipe culvert to cross four existing ephemeral drainage features that intercept the trail. The Arizona crossing will be located at the northernmost corner of Como Street and Stoneman Street and will consist of a concrete apron and rock splash pad. The approximately 55 feet long span bridge will be located at the terminus of Ontario Way and will be constructed either as cast-in-place concrete abutments spanned by hollow-core precast concrete planks, or an alternate clear span design such as open bottom arch culverts. It will completely span the ephemeral feature, with no footings or other material placed within the feature. It is anticipated that the crossings will require the use of a backhoe and/or mini excavator for the cast-in-place concrete abutments, and an articulated lift to hoist the hollow-core precast concrete planks into position. Impacts from the installation of the crossings will be confined to the permanent and temporary impact footprint. The existing culvert located at the eastern end of the trail will be replaced and extended to accommodate the trail width. The Project will require a total of approximately 2,765 cubic yards of asphalt (consisting of 655 cubic yards (cy) of hot mix asphalt,1,850 cy of Class II aggregate base, and 260 cy of DG) imported to the site. Earthwork would include approximately 9,405 cy of cut and 6,375 cy of fill, resulting in export of 8,363cy and import of 5,335 cy. Cut and fill slopes would be a maximum 2:1 gradient. Temporary steel plate bridges and/or other temporary clear span means required of the contractor would be implemented during construction should any of the avoided features need to be temporarily crossed during construction. Temporary construction access will be provided via existing paved roadways, the Levee Trail, and within the temporary impact area. Temporary construction staging areas will also be located onsite within the mapped temporary impact area or off-site within the existing disturbed and developed areas.
