Approve plans and specifications for Phase II of the Landscape Water Management Program (Project R0007). Award construction contract to Valley Crest Landscape Maintenance for $1,343,181, and authorize a 15 percent contingency in the amount of $201,477, for a total amount not to exceed $1,544,658. 2. Transfer $20,000 in project savings from R0006357-5161.001 Landscape Water Management Phase IA to R0007357-5161.001 Landscape Water Management Phase II for non -contract related miscellaneous irrigation equipment. 3. Authorize the City Manager or designee to modify the award in the event that issues of impossibility of performance arise, subject to City Attorney approval. BACKGROUND The City's Landscape Maintenance Districts (LMD) manages 720 acres of landscaping located within approximately 40 independent LMD zones. Over 500 irrigation controllers are used to apply and regulate the amount of water used on the landscaping. Therefore, managing the LMD's water use has been and remains a top priority. The irrigation controller replacement program Iwas created to replace controllers which have exceeded their useful life or are obsolete due to improved technology. When fully phased -in over the next calendar year, staff anticipates the new smart controllers will reduce LMD's water use by 20 to 40 percent, which equates to an annual water savings of approximately 200 to 350 million gallons. A'PRiV D In 2009, staff initiated a process to identify a state-of-the-art irrigation controller that meets the City's high standards. The irrigation controller ultimately selected by the City and installed as part of the Phase 1 and I of this project can automatically manage irrigation programming based on real-time weather conditions, including immediate program shutdown in the event of precipitation that exceeds a preset minimum value. In addition, the selected controller can also be programmed to know the plant type being watered, soil conditions, and sun orientation. All controller settings, programming, operations, system warnings, and consumption reporting is sent and received via wireless technology to as many or as few recipients as deemed necessary by staff. The final phase of this multi -phased irrigation replacement program was approved as part the Fiscal Year (FY) 2010-11 Capital Improvement Program (CIP) budget. This phase will replace 336 irrigation controllers in 21 LMD zones. An invitation to bid for the procurement and installation of LMD irrigation controllers was published October 20, 2010, forwarded to the appropriate trade journals, VIA, and Chamber of Commerce, provided to 22 suppliers on file, and posted on the City website. The bid specifications requested that contractors provide a bid to purchase and install 336 irrigation controllers in locations selected by the City. As this is a public works project procured under the State's Public Works Code, the use of the City's local preference ordinance is precluded by law, and the bid will be awarded to the lowest qualified bidder. The bid process was highly competitive; seven companies submitted bids which were opened November 22, 2010. The bid prices ranged from the the low of $1,343,181 to the high of $1,664,712. The results follow: Company Valley Crest Landscape Rock Bottom Inc. American Landscape Marina Landscape O&J Landscape ISS Grounds Control Green Horizons Landscape Location Bid Amount Calabasas, CA $1,343,181.03 Bakersfield, CA $1,367,386.00 Canoga Park, CA $1,440,745.00 Anaheim, CA $1,496,505.00 Moreno Valley, CA $1,505,102.71 Santa Clarita, CA $1,622,582.54 Escondido, CA $1,664,712.50 A review of the bids was conducted for accuracy and completeness. Staff recommends the project be awarded to Valley Crest Landscape Maintenance, the lowest responsive bidder, for $1,343,181, and authorize a 15 percent contingency of $201,477, for a total amount not to exceed $1,544,658. Valley Crest possesses a State Contractor's License and, is in good standing with the ►0 State Contractor's License Board. Reference checks indicate the contractor has satisfactorily completed similar work for other public agencies. Over the last several years, the City has consistently implemented projects and programs to reduce water use while maintaining landscape at the City's high standards. (Attachment A highlights the programs and projects.) Additionally, the City's controller replacement program was recognized in July 2010 by Water Efficiency magazine, the journal for. water resource management, as "The World's Largest Smart Water Implementation." ALTERNATIVE ACTIONS Other action as determined by the City Council. FISCAL` IMPACT There is no impact to the General Fund, and sufficient funds were approved in the FY 2010-11 CIP Budget. ATTACHMENTS LMD Irrigation Accomplishments Attachment A City of Santa Clarita, Landscape Maintenance Districts Water Management Accomplishments o Completed Phase I and IA of the Irrigation Controller Replacement Program, resulting in the successful replacement of 166 dated irrigation controllers. o Increased use of mulch to keep soil cooler and reduce surface moisture evaporation. o Replaced three miles of turf medians with shrubs and other water -efficient plant material saving an estimated one million gallons of water annually. o Completed median improvement project for Wiley Canyon Road, saving an additional one million gallons of water annually with the replacement of turf with shrubs and update of the 30 -year-old irrigation system. o Installed synthetic turf on Magic Mountain Parkway median. The use of synthetic turf is projected to save more than 75,000 gallons of water each year. o Use self-monitoring irrigation controllers and flow meters which detect problems and automatically shut off City irrigation systems in the event of a main line failure. o Valencia Summit Park - The previous inefficient controller was replaced with a "SMART" controller in August 2009. Comparing the period August 2009 through April 2010 to the previous period, we reduced our consumption by over one million gallons. In fact, this period saw our lowest use in Summit Park in the last 11 years! o During the last year, staff completed a comprehensive irrigation assessment of one of the City's most water -intense landscape maintenance zones. Through the replacement of pressure regulators, irrigation valves and hardware, and irrigation programming adjustments, staff reduced water consumption for this zone by 5,177,068 gallons compared to the previous year.
