Page 7 - Efficient Irrigation and Landscape Design Standards

The City of Hayward, CA, has similar goal statements to the California MWELO:
• Encourage the use of a watershed approach and reducing compaction, incorporating organic matter that increases water retention, and promoting productive plant growth that leads to more carbon storage, oxygen production, shade, habitat and aesthetic benefits.
• Establish provisions for water management practices and water waste prevention for existing landscapes.
• Set a Maximum Applied Water Allowance as an upper limit for water use and reducing water use to the lowest practical amount.
From the King County, Washington Municipal Code:
The purpose of this chapter is to preserve the aesthetic character of communities; to improve the aesthetic quality of the built environment; to promote retention and protection of existing vegetation; to promote water efficiency; to promote native wildlife; to reduce the impacts of development on drainage systems and natural habitats; and to increase privacy for rural area and residential zones by:
A. Provide visual relief from large expanses of parking areas and reduce perceived building scale.
B. Provide physical separation between rural area or residential zones and nonresidential zones.
C. Provide visual screens and barriers as a transition between differing land uses.
D. Retain existing vegetation and significant trees by incorporating them into the site design.
E. Provide increased areas of permeable surfaces to allow for:
» Infiltration of surface water into groundwater resources.
» Reduction in the quantity of storm water discharge.
» Improvement in the quality of storm water discharge.
F. Encourage the use of native plant species by their
retention or use in the landscape design.
G. Require water use efficiency through water budgeting and efficient irrigation design standards.
H. Encourage the use of a diversity of plant species that promote native wildlife habitat.

policies are essential to: accommodate growth without large infastructure costs,
protect recreation and habitat, ensure quality
water for the future.
