Background/Discussion: |
This program is a three-year plan to convert approximately 58.5 acres of turf in City-maintained landscaped drainage basins into xeriscape areas. Several factors are involved in converting sod to xeriscape, including the cost associated with sod removal, edge preparation, pre-emergent, as well as the installation of 3/4" screened granite, drip irrigation, shrubs, and trees. Maintenance costs of the existing irrigation system would be reduced along with the costs associated with the annual mowing and turf maintenance contract. Removing the grass areas will also reduce water usage and the associated water costs by 50% to 75%. As water management is a key part of Chandler's commitment to a sustainable supply of water in the future, this program fulfills the goals established to reduce water consumption where possible. As a result of Chandler's smart water management, including infrastructure investments, diverse water supplies, water reuse, drought preparation, and water conservation, the city has been able to prosper in its desert environment. The project scope of work consists of preliminary site design concepts, project administration, field survey, geotechnical investigation, utility coordination, permitting assistance, cost estimates, public outreach, and construction document preparation. The agreement completion time is 500 calendar days following Notice to Proceed. Any projects under this program will involve significant public outreach to adjacent residential and business areas prior to conversion to xeriscape. There is a significant saving in money and water from the impact of these projects. It is estimated these project will save the city more than 20 million gallons of water each year, which would result in the city saving more than $50,000 in water usage each year, plus landscape maintenance costs. Of note, this program impacts public drainage areas only; no developed City parks are included. |
