Po Policy and Re Regulations Matter. SM SMALLER LOT SI SINGL GLE FAMILY DEVELOP OPMENT 1 Studies found 10 to 60% water savings with increased density of single- family residences. 2 MU MULTI FAMI MILY DEVELOPME MENT Multifamily units consume 35 to 50% less water than single family detached homes. If a high-density development requires cooling towers, the savings may decrease or be eliminated. EF EFFICIEN ENT LAN ANDSCAP CAPIN ING AN AND IR IRRIG IGATIO ION 3 Landscape code requirements can reduce outdoor water use by 35- 50%. IN INDOOR OOR WATER USE 4 Water efficient fixtures and appliances, building and plumbing codes can have significant savings.

The Master Plan 7

“ The general location and extent of an adequate and suitable supply of water.” IF the master plan includes a water supply Colorado Co element, the planning commission shall consult with the entities that supply water for use Master Ma r Planning within the [jurisdiction] to ensure coordination on water supply and facility Re Requirements planning , and the water supply element shall identify water supplies and facilities sufficient to meet the needs of the public and private infrastructure reasonably anticipated or identified in the planning process.

Integrating Water into the Comprehensive Plan Plan Components Definition and Description Opportunities to Connect to Water • Vision A statement of the desired future of the Integrate principles of sustainability and resiliency into the community and the ideals the community community’s vision. aspires to achieve. Community Profile An overview of the community’s trends • Ensure the water supply projections and population projects and future demographics. are aligned, regardless of number of water providers. • Inventory and evaluate water infrastructure for conveyance, treatment and resiliency. • Assess watershed health. • Identify challenges and opportunities with managing water supply, water demand, watersheds and aquatic ecosystems. • Goals, Objectives and A statement of desired community Identify water-resource related goals and desired policy Strategies conditions, targets for achieving goals, and actions, including regulatory recommendations. courses of action or tasks to achieve each objective. Future Land-use Plan A map and/or plan which identifies the • Identify specific geographic areas where future development types of land uses that are desired for should be mitigated to protect critical water resources. • different districts in the future. Foster more efficient land-use development patterns through compact form. • Ensure future growth is designated in areas where water is available, sustainable and resilient. Implementation Plan A work plan that prioritizes future actions • Ensure implementation of priority water-related projects, and investments. policies and programs by creating a detailed action plan.

The Role of Compact Form in Water Savings What percentage of total development pattern will yield water saving benefits?

A. ADEQUATE WATER SUPPLY C.R.S. § 29-20-302(1) “sufficient for build-out of the proposed development in terms of quality, quantity, dependability, and availability to provide a supply of water for the type of development proposed and may include reasonable conservation measures and water demand management measures to account for hydrologic variability ” 14

State of Colorado Requirement for Applying Water Adequacy Review Counties Municipalities Size of Development for Adequacy Determination 2 or more lots 50 or more lots State Engineer Review Required Not Required, Optional Determination Timing Flexible within Flexible development review 15

BEST PRACTICES 1. Identify Permitted Water Source 2. Provide Proof of Water Rights 3. A Requirement/Methodology for New Development Water Demand 4. Specific Water Supply Adequacy Verification Process 5. Specific Water System, Distribution, and Connection Standards 6. Define Potable Water Standards and Verification Process 7. Link Water Supply and Zoning 8. Include Conservation & Efficiency Requirements 6. Clarify Timing for When Proof Required in Approval Process 16

Breaking Down The Water Supply Requirements You Are Answering These Questions That Match These Requirements 1. How much water is requires for the = water demand calculation new development? 2. Where is the water going to come = the water source(s) from? = adequacy verification process 3. Is the water supply adequate and sustainable? = water quality test 4. Is the water supply potable? = water system design 5. How will the water be delivered? = plan approval process 6. When will you require proof? 17
