The Town has experienced a recurring flooding problem in the Central Basin, which will not be solved unless future development flows are diverted away from the do~mtown areas, and a storm system to convey water to the City Park box culvert is constructed. We would, therefore, recommend that the first phase of construc- tion focus on the installation of the Railroad Avenue System, Much of this work can be completed by Town forces, which may help the Town when applying for block grant funding or economic development grants. The total cost of the Central System is estimated at $416,800 for the piped system, and approxima- tely $348,000 for a concrete channel system (assuming reinforced concrete pipe is used). Development of the systems proposed for the East and West Flow Paths will be dependent upon the deve 1 opment of properti es tri butary to the systems. Currently Ordway West is proposing single-family construction, and already has a series of new streets in pl ace on the property. Similarly, the property north of Ordway West has rough cut streets. Within the East Flow Path, the RGF property is currently developing plans to construct multi-family units, and development planning is undero'/ay. For these reasons, it is recol1111ended that the second phase of construction of the storm drainage system be the systems servi ng those three proposed developments. Constructi on of these segments will advance the diversion concept, and also help to solve an existing poor drainage conditions adjacent to the Nursing Horoo. Phase 3 is recol1111ended to be the regrading of the Town of Ordway Ditch, and the construction of the box culvert under the railroad at Colorado Highway 71. The construction of the box culvert will effectively eliminate the shallow flooding which would occur along Railroad Avenue. Once the box has been built, discussions should begin with the property owners, and County, concerning the outfall channel for the East Flow Path to Lake Meredith. Construction of this box will substantially eliminate all of the floodplain shown on the Town of Ordway Flood Hazard Boundary Map (FHBM). Later phases must be advanced as development proceeds. With the constructi on of Phases 1 through 3, the maj ority of the exi sti ng storllltolater '-f.. ."J I I I i I ----
