A new water meter will also be <br />needed to complete this project. The cost of the new meter will add an additional $850.00 <br />to the project. Therefore, the overall project cost is estimated to be $16,333.75. Staff <br />checked references on the top bidders for both the irrigation installation and the plumbing. <br />Anderson Irrigation has extensive experience installing irrigation systems on sports � elds. <br />Cities or agencies that Anderson Irrigation has worked with: Anoka Hennepin School <br />District, City of Blaine, City of Little Canada, City of Otsego, City of Ramsey and the City <br />of Roseville. Village Plumbing, Inc. has worked with several surrounding municipalities <br />such as the City of Shoreview, City of Little Canada and the City of Roseville. <br />The Cummings Park fields serve as one of the two main sport fields in the City. The fields <br />are utilized three seasons of the year by City programs and association programs. The <br />fields were in poor shape last spring/summer and without irrigation, staff found it difficult <br />to fix bare areas and holes. In 2001 when the pavilion was built, the City included <br />installation of a pipe for the possibility of a future irrigation system. This field is heavily <br />used and the result is a poor playing field. The irrigation system will help keep the fields in <br />playable condition. Healthy grass is an essential element of any outdoor sport field. Thick, <br />green, lush turf provides a safer surface for athletes, reducing the amount of injuries <br />experienced on the playing field. It is also aesthetically pleasing. Water is a necessary <br />component to keep turf in healthy condition. It is recommended that turf receive 1" of <br />water per week. Irrigation systems are typically installed to supplement rain water to <br />provide the needed 1" of water per week. As sport fields develop bare spots in high traffic <br />areas such as goal mouths, an irrigation system can assist in keeping newly seeded areas <br />moist to help promote seed germination and long term establishment. Dormant and dry turf <br />grass is more susceptible to long term damage due to the aggressive heavy traffic on sport <br />fields. <br />A soil sample has been collected from Cummings Park and sent to the University of <br />Minnesota for testing. The results of this soil sample will help determine the required <br />nutrient needs of the soil. This will demonstrate how much fertilizer, and what type of <br />fertilizer these fields need. The soil on these fields is primarily a heavy clay content. This <br />type of soil vvorks v�ell with irrigation systems with the most effective method being to <br />apply water slower over longer durations. Fertilization, aeration and irrigation work <br />together to provide q�.ality turf. We will be reviewing our current maintenance practices <br />for this field, in order to maximize the benefits of irrigation. <br />Cost Benefit Analysis <br />The spring and summer of 2009, city staff put together a make shift sprinkler system on <br />occasions at Cummings Park when we had time. This probably occurred once or twice a <br />�nonth. Staff saw a drastic improvement in bare and damaged areas on the field after this <br />I IMet�o-anet. us l ardenhills IPR�PWIParks 11Vlemos I Council Memos 1032910 Cummings Park Irrigation. doc <br />
