Help us be Water Smart - Report water leaks!
If you observe a broken sprinkler or other water leak, give us a call at (530) 757-5620 or email us at firstname.lastname@example.org If the report is after hours and is of an urgent nature, such as a broken line or gushing water, you may also call non-emergency police dispatch at (530) 747-5400 and they will contact our Irrigation staff.
Current Conservation Efforts Underway in Parks and Greenbelts
Our goal is to reduce water consumption by at least 30% within the parks, greenbelts, and streetscapes maintained by the City. Current water conservation measures already implemented, include but are not limited to:
- Implementing deficit based watering rather than optimum irrigation. This results in less overall water consumption and less frequency of watering in parks and greenbelts. Due to inconsistent uniformity in applying the water due to aging infrastructure, deficit watering can result in highly stressed areas in parks and greenbelts. Staff are monitoring and attempting to repair all broken heads, lines and valves to improve overall uniformity and efficiency of all irrigation systems.
- Implementing cycle soak programing for irrigation systems. This programming results in a slower application of water over a longer period of time to help reduce run-off and allow the water to absorb more effectively into the turf and soil. Several higher water volume heads (4 gallons/minute) have been reduced to smaller flow heads (1½ gallons/minute) to assist with a more even distribution of water.
- Currently replacing standalone controllers with SMART or central-based controllers and implementing evapotranspiration (weather based) programs. The City currently has 285 irrigation controllers, with 130 of them being central based.
- Evaluating current park and greenbelt irrigation system performance uniformity and efficiency - Replacing damaged, aged and poor performing heads with high efficiency rotors. About 400 heads and nozzles have been replaced to date, with an estimated 1,500 heads and nozzles to be replaced by next spring.
- Adding flow sensing with master valves to many of the existing City controllers which helps manage water consumption, and receive “real time” high and low flow alarms as well as automatically shutting down irrigation systems for large line and mainline breaks. Additional flow sensing is continuing to be added where applicable.
- Several parks have been comprehensively retrofitted with the new central-based controllers, and the irrigation systems have been upgraded with high efficiency rotors and nozzles. Additional parks and greenbelts will be completed in their entirety over the next two years, with many of them being fully completed by next spring.
- Converting the irrigation of Community Park to well water rather than the City’s potable water system. Other potential locations, such as Northstar and Walnut Parks, are also being explored for potential well conversion for irrigation purposes.
- Conducting water audits and developing more refined annual water budgets for each park and greenbelt location.
- Updating the City’s Landscape Specifications and Guidelines which has not been updated since 2004. This document will assist the City in meeting current and new regulations for water usage, implement best water management practices, and develop additional demonstration turf reduction areas and irrigation improvements.
- This summer, the City is identifying several turf conversion areas in many of the parks and greenbelt areas. These lower public use areas are currently being posted, and irrigation to these areas will either be shut off completely or dramatically reduced in order to maintain any existing trees in the designated area. Future conversions of these areas may include increased mulching, planting of drought-tolerant landscaping, and/or addition of trees. Residents will most likely begin to see re-planting occur in late fall and winter as the weather begins to cool.
More information and maps of designated turf conversion locations within the parks and greenbelts will be coming soon! We encourage residents to check in for periodic updates, and contact the Parks & Open Space division for any further questions or concerns at (530) 757-5656.
