Lino Lakes Public Services Department <br />600 Town Center Parkway <br />Lino Lakes, MN 55014 <br />(651) 982 -2440 Fax (651) 982 -2439 <br />Memorandum <br />To: Mayor Bergeson and City Council Members <br />From: Rick DeGardne , Public Services Director <br />Date: April 30, 2008 <br />Re: Rain Sensor Retro -fit Program Options <br />During the April 7, 2008 City Council Work Session, staff was directed to provide some <br />alternatives pertaining to the rain sensor retro -fit program. After contacting area <br />distributors /contractors, staff has determined that most economical way to acquire the rain <br />sensors is through Toro's program. The City can purchase between 100 - 500 contractor <br />grade rain sensors annually at a cost of $50 each (Retails for $117). Based upon City <br />Council discussion, staff recommends purchasing 200 rain sensors for 2008 and <br />reevaluating the program next year. <br />Option #1 — Make available the rain sensors for $50. Residents would be responsible to <br />install them. Staff would follow up to verify that the rain sensor is properly installed and <br />functioning. There would be no net impact to the Water Operating Budget (Buy the rain <br />sensors for $50 and sell them for $50). <br />Option #2 — Make available a rain sensor and installation for $50. After contacting area <br />irrigation contractors, staff recommends utilizing Northway Irrigation to install the rain <br />sensors. Northway Irrigation has agreed to a price of $37.50 per installation. They are also <br />a Toro distributor. City staff would set up appointments and be the primary contact for <br />residents. This would also provide an opportunity to perform a system audit (if the resident <br />is interested) to ensure that the irrigation system is performing properly /efficiently. <br />Northway Irrigation is a licensed contractor. The maximum impact to the Water Operating <br />Budget would be $7,500 (200 installations @ $37.50). <br />Option #3 — Provide a rain sensor and installation at no cost to the homeowner. This option <br />would most certainly provide the best opportunity of having irrigation systems equipped <br />with rain sensors. The maximum impact to the Water Operating Budget would be $17,500 <br />(200 installations @ $87.50). <br />C: \Documents and Settings\ rick .degardner.METRO- INET\Desktop \Rain Sensor Options 4- 23- 08.doc <br />
