<br />CASE # I <br /> <br />IRRIGATION FOR RIVERDALE PARK - 2008 PARKS CAPITAL IMPROVEMENT <br />By: Mark Riverblood, Parks Supervisor <br /> <br />Background: <br /> <br />The 2008, Parks Capital Improvements Program (CIP), identifies irrigation as a need for <br />Riverdale Park. Earlier this year, the Park and Recreation Commission forwarded a work plan to <br />City Council that scheduled this project for construction in the fall of 2008. <br /> <br />The impetus for this project is that during dry periods the turf quality declines substantially, <br />resulting in a park space that is unattractive and underutilized. In addition, the park has been the <br />subject of significant volunteer tree planting contributions, (with many of the park trees <br />negatively affected during droughty periods). The most recent tree planting was the 2008 Arbor <br />Day collaboration between the Environmental Policy Board and Village Bank of Ramsey. <br />Further, neighbors of the area have been watering trees for many years with garden hoses relative <br />to a concern for the trees. <br /> <br />Observations: <br /> <br />The 4-acre Riverdale Park was dedicated to the City as part of the platting of the Rivenwick <br />single family home subdivision along the Mississippi River in the 1990's. The park's primary <br />purpose is to serve as a neighborhood resource for those residents south of Trunk Highway 10 - <br />169 near the future Mississippi West Regional Park, and Ramsey's boundary further to the east. <br />Since the initial construction of the park, many townhome units have been platted west of <br />Riverdale Park. The attached map shows the proximity of the hundreds of families who benefit <br />from the park. <br /> <br />Also attached are the CIP worksheet, and the schematic of the proposed irrigation project. Below <br />are the estimated construction costs of this project, as well as the annual anticipated operation <br />expenses. <br /> <br />Irrigation Detail <br /> <br />Irrigation, 12-zone, 2-wire system <br />Watermain connections, concrete pad, RPZ <br />Electric service, (Connexus) . <br />Meter socket and minor electrical <br />Contingency <br />Trenching, blacktop repair, restoration etc. by city forces <br />Total <br /> <br />$36,000 <br />$6,000 <br />$1,600 <br />$900 <br />$500 <br />N/C <br />$45,000 <br /> <br />The irrigation system annual operating cost is estimated at approximately $1,778 per acre (2009 <br />dollars). This includes water, electricity, repairs and maintenance activity such as winterization. <br />This project at 4-acres then should be considered to require about $7,112 per year, in relation to <br />
