SR - AGR-6227 - EISENHOWER PARK BOOSTER PUMP INSTALLATIONAGENDA ITEM May 12, 2015 TO: Honorable Mayor and Members of the City Council THRU: Rick-Otto FROM: Marie KnigJ Community 1. SUBJECT ReviewedNerifie City Manage Finance Dire All To Be Presented By: Marie Knight X Cons Calendar _ City Mgr Rpts Council Reports Legal Affairs Boards /Crates _ Public Hrgs Admin Reports Plan /Environ Contract with Clean Cut Landscape in the amount of $89,971.00 for installation of an irrigation booster pump at Eisenhower Park. 2. SUMMARY Due to insufficient water pressure at Eisenhower Park a new irrigation booster pump will be installed. This project is consistent with the City's irrigation efficiency efforts, including the future project to install a Calsense irrigation control system at Eisenhower Park later this year. The pump will allow for greater efficiency of the Calsense system by providing the ability to deliver the proper amount of water over a shorter period of time, making it possible to fit watering schedules into limited windows of available time. 3. RECOMMENDED ACTION Approve Contract and authorize the Mayor and City Clerk to execute on behalf of the City. 4. FISCAL IMPACT Funds are available to cover the cost of the Contract as follows: 511.7021.56015.20184 (Booster Pump Installation at City Parks) $89,971.00 5. STRATEGIC PLAN GOAL(S) 3a: Renovate, refurbish and improve public use places and spaces that are functional and safe. ITEM 3�- Jq , 05/12/15 6. GENERAL PLAN IMPLEMENTATION Policy 5.1 Maintain existing City parks at levels that provide maximum recreational benefit to City residents. 7. DISCUSSION and BACKGROUND Background Eisenhower Park is a large -scale (16.46 acres) active community park that was acquired in 1969. The park features a reservable green space, meandering stream, walking paths, tot lot, and a lake for fishing. Often, as a city's population grows and demand on utilities expands, water pressure that was adequate in the design and development of a project is not sufficient 20 or 30 years later. This is the case with Eisenhower Park. The existing irrigation system does not have the adequate water pressure needed to efficiently operate valves at the outer edges of the park, and a consequence of this is that water cannot be efficiently delivered to adequately irrigate the landscape. While we endeavor to reduce the amount of water used for landscape purposes, landscape that is irrigated must be done as efficiently as possible. Discussion The new booster pump will be located above - ground and installed on a concrete pad approximately 6'x 5' in size. It is the City's intent to locate the pump in the same enclosure housing the irrigation backflow device. This new booster pump is consistent with the City's efforts to improve efficiencies in the delivery of irrigation water, and will become an integral partnering component to the new Calsense irrigation control system at Eisenhower Park planned for later this year. The current operating pressure for Eisenhower Park's irrigation system does not allow for maximizing the use of the watering window during park closure hours from 11:00 pm — 5:00 am. In order to maximize use of the available watering time window, it is necessary to operate multiple valves concurrently. The proposed booster pump will increase the operating pressure to the system, allowing for multiple valves to water at the same time, thereby delivering water to the landscape more efficiently. Paired with the planned installation of a Calsense weather -based irrigation control system, a more efficient delivery of water to the landscape can occur. By maximizing the use of available time to water, the Calsense system is able to push the maximum available water out, optimizing delivery by pairing valves by their water demand. This also improves the ability to use multiple start times for each zone, maximizing penetration of water into the soil and minimizing runoff. The Community Services Department sent out a public /formal bid for this work based on approved plans, details and specifications (Bid #145 -41 Eisenhower Park Booster Pump Installation). Bids were received on April 2, 2015 from five qualified contractors. The Community Services Department has selected Clean Cut Landscape as the lowest responsible bidder to complete this work. The contractor will commence work on this project on or about June 1, 2015 and said work will be completed in less than 30 working days. ITEM 05/12/15 The amount of the bid received from Clean Cut Landscape is $81,792.00. The Contract provides for a contingency amount of 10% ($8,179.00) for a total contract amount of $89,971.00. The contingency amount will only be used in the event of unforeseen conditions and circumstances that may arise during the course of this job. 8. ATTACHMENTS Bid Abstract Draft Contract ITEM 05/12/15
