<br />subdivisions as well as the Downtown Fort Collins Airport and low-income residential housing. <br />The North College Avenue Corridor and the East Mul~erry Corridor are also within the hazard <br />area. The City and County have identified northeast Fort Collins as the logical growth and <br />expansion areas for new development. <br /> <br />, <br /> <br /> <br />, <br /> <br />e <br /> <br />Proposed Proiect <br />The Dry Creek drainage basin covers an area of approximately 65 square miles. <br />Currently, there are over 8.0.0 structures subject to flooding within the effective FEMA regulatory <br />floodplain of Dry Creek. The goal of the project is to build structural flood control features to <br />remove flood impacts to existing and future City aq:d County developments while providing <br />enhanced water management and flood control benefit~ for the Irrigation Company. <br />i <br /> <br />ECI, Inc. prepared a project feasibility study ih cooperation with Nolte Associates, Inc., <br />Steigers Corporation and BBC Research and Consulting. The feasibility study analyzed several <br />alternatives for the proposed improvements and, using the least-cost approach, recommended the <br />improvements outlined below. <br /> <br />The project involves maximizing the use of detention capability existing in the private <br />Douglas Reservoir owned by the Irrigation Company; in lieu of building a new storage facility. <br />In return for being allowed to use an existing irrigatidn storage reservoir for stormwater storage, <br />the City and County would pay one-half the cost of a new 42-inch irrigation water supply <br />pipeline. The pipeline will provide a capacity of75 d's between Douglas Reservoir and the Terry <br />Lake Inlet Feeder Canal. Its purpose is to allow better water management to the Irrigation <br />Company and the Dry Creek lower basin. <br /> <br />e <br /> <br />The project design features include the following: , <br />1. Segmented enhanced regulating weil1 on the spillway for Douglas Reservoir - <br />$3.0.0,.0.0.0 ' <br />2. Overflow spillway segment on the Larimer County Ditch at its junction with Dry <br />Creek and the feeder canal from Douglas Reservoir - $45,.0.0.0 <br />3. Pipeline irrigation conveyance - $6,6.0.0,.0.00 <br />4. Additional flood control storage in the middle basin - $2,247,.0.0.0 <br />5. Additional detention near the Larimer~ W eld canal - $157,.0.0.0 <br />6. Control structures and Terry Lake Cmital improvements - $582,.0.0.0 <br />7. Easements for existing storage behin4 road and railroad fill- $891,.0.0.0 <br />8. Modifications to the Larimer- Weld cljnal- $2.0.0,0.0.0 <br />9. East Vine diversion channel- $l,.o.o.o;.o.o.o <br />1.0. SCADA System (instrumentation/flood warning) - $8.0,0.0.0 <br /> <br />The cost estimate for this alternative inclUding contingencies for engineering design, <br />permitting, legal and construction fees is $12.6 mi1l~on. <br /> <br />Public Involvement <br />Throughout the planning and feasibility studies for this project, the City and County have <br />focused substantial efforts to provide information (;>ll the project to the public.
