1 2 3 4 5 6 7

Projections for future population and drivers of growth. Uniform application to all developments. Adequacy, sustainability, and vulnerability of the water supply. The type of development occurring in the community and where it should occur. The source, capacity, and conditions of a community’s water supply, distribution systems, and water related infrastructure. Health conditions of the watershed. Current programs and projects.

BEST PRACTICES

PLANNING PLANNING & & POLICY POLICY MAK MAKING ING

The sustainability of a community is dependent upon the availability of water; considerations of future water needs must be integral to decision making.

BEST PRACTICES

ADEQU ADEQUATE AND TE AND SUST SUSTAIN AINABLE ABLE WA WATER TER SUP SUPPL PLY REQUIREME REQUIREMENT NT

Since water is a limited and constrained resource, prior to approving new development, the water supply should be demonstrated as adequate and sustainable.

Toolbox 2.

Clear definition of adequate and sustainable supply including demonstration of water availability and time period. Water demand projections for new development. Water right inventory and legal demonstration. Uniform application to all developments. Expert review process. Maps of water resource areas.

BEST PRACTICES

WA WATER TER SMAR SMART T LAND USE LAND USE POLICY POLICY

As a population increases, the demands

• n water

supply and water related infrastructure including water treatment plants, delivery systems, wastewater and watersheds will also increase.

Toolbox 3.

Promote higher density and compact development, especially where there is adequate infrastructure. Promote water saving landscaping standards. Promote the use of new water e

efficient plumbing and building standards.

Land Use Methods to Save W ater.

1

SMALLER LOT SINGLE FAMILY DEVELOPMENT Studies found 10 to 60% with water savings with increased density of single family residences, mostly due to less irrigated lot area. Savings increase as lot size decreases. Sweet s spot is 7 to 10 DU/A.

2

MULTI FAMILY DEVELOPMENT Multifamily units consume 35 to 50% less water than SF detached homes. If a high-density development requires cooling towns, the saving may decrease. LANDSCAPING AND IRRIGATION RESTRICTIONS Turf area restrictions and xeric landscape requirements can reduce water by 35-50%.

BEST PRACTICES

HEAL HEALTHY & THY & RESILIENT RESILIENT WA WATERS TERSHEDS HEDS

The effects of increasing development, climate change, and natural hazards can all degrade the quality of the watershed impacting both water yield and water quality.

Toolbox 4.

Minimize pollution from urban and agricultural runoff. Minimize sedimentation due to soil disturbances, vegetation loss, and erosion from new roads and development. . Minimize destruction of riparian areas resulting from development and change in climate. Plan for inconsistencies and vulnerabilities in the watershed due to drought and natural disaster. Reduce impervious surfaces and rapid runoff to increase infiltration from natural precipitation. .

01 01 02 02 03 03 04 04

Adopt stormwater management and site development standards that utilize low impact design best practices. Adopt development standards for soil erosion mitigation. Adopt plans for disaster mitigation, stormwater management, and watershed management Map sensitive areas: watersheds, wetlands, riparian corridors, infiltration zones, groundwater basins, and disaster prone areas.

05 05

Adopt surface and groundwater districts with standards to protect water bodies and aquifers.

06 06 07 07 08 08

Adopt stream buffers and setbacks to protect water quality. Adopt vegetation protection standards to protect riparian corridors. Create zoning districts with lower densities and/or cluster development to protect surface and ground water sensitive areas.
