Local governments may assist in this process by adopting related policies and resolutions, and by identifying structures which should not be rebuilt or repaired after substantial flood damage or destruction. Parks, Recreation, and Open Space well as a recreation trail system, linking major streets and parks and recreation nodes, while providing a safe and aesthetic transportation alternative. When compl eted thi s trail system will connect the Cities of Wheat Ridge and Arvada to the future South Pl atte River trail system, which will extend into downtown Denver, along the Pl atte River Greenway. The escal ating cost of government and an increasing demand by the publ ic for more efficient provision of public services has forced government, at all levels, to consider multiple use opportunities of public projects. M impor- tant aspect of this demand is the combination of parks and outdoor recreation activities and facilities with stream corridors and urban drainageways. Recreation use potential of the lower Clear Creek corridor has been recog- nized by all governmental entities, state, regional, county and local, having jurisdiction along Clear Creek. The trail improvements pl anned as a part of this study are discussed in detail in the Commentary of each Major Drainageway Pl an drawing in this report. RECOMMENDED STRUCTURAL IMPROVEMENTS The lower Clear Creek Master Drainage Pl an has identified several areas along the corridor where the trail system is i ncompl ete. In conj unct i on wi th recommended improvEffients and modifications, the required maintenance and access service roads for the creek have been integrated into the pl anned and exi sting recreation trail system. When compl eted, the combination hi kerf biker/maintenance trail system will parallel lower Clear Creek's entire length from its confluence with the South Platte River to Youngfield Street. This multiple-use facility will provide maintenance access to the creek as Concern by the involved entities to reduce flood hazards at several locations along lower Clear Creek has resulted in the development of certain select, or 1 imited, structural improvements at major street crossings. In accordance with the "Selected Phase B Plan" for lower Clear Creek, recommendations have been made for bridge and/or channel improvements at Kipl ing Street, Tennyson St reet, Lowell So ul ev ard, Denver and Ri 0 Grande We stern Ra il road, Pecos Street and the confl uence wi th the South Pl atte River. Channel and bridge improvements have been designed util izing the design criteria contained in the Denver Regional Council of Government's Urban Drainage Criteria Manual, vollll1es 1 and 2, and other acceptable criteria for the Denver metropolitan area. Appendix C contains the recommended structural criteria for pl anning and design of major drainageway improvements on lower Clear Creek. During final design care must be taken at transitions to the natural channel to ensure that the character and magnitude of fl oodwaters does not cause more hann than fonnerly. The Ci ty of Wheat Ri dge has acqui red much flood-prone 1 and along the creek and has dedicated it to park and open space uses. The Wheat Ridge Greenbelt and trail system has been pl anned and partially constructed along the creek within Wheat Ridge's jurisdiction, from Youngfield to Wads\\Orth. The Colo- rado Division of Highways has planned, and is constructing, a hiker/biker/ maintenance trail system along Cl ear Creek from Wads\\Orth to Interstate-25 in conjunction with their Interstate-76 construction project. A trail presently exists from Broadway to the confl uence with the South Pl atte River, in Adams Co unty. Reach III B (gOO-Feet Upstream of Kipl ing Street to Upper Limit of Study Area Sta. 559+O0 to Sta. 658+00). The adopted strategy for floodpl ain management in this segment is Floodplain Preservation. No structural improvements are recommended in thi s reach.
