PRESENTATION OBJECTIVES

• Describe the circumstances Utah is facing with a growing population and limited water supply.

• Expand integration of water and land use planning

• Foster support for sustainable landscape practices that are designed for our region.

• Encourage adoption of regulations and ordinances to increase water use efficiency and reuse.

• Develop partnerships to promote conservation programs and practices.

NEED FOR PARTNERSHIPS

“State and water conservancy districts should continue to strongly encourage municipal governments to create or update existing ordinances that support conservation. Although education programs

are important, they aren’t enough.”

“Establish better connections between city planning departments and water conservation districts. Development of communities and a continued supply of water are too closely linked to be planned

without one another.”

Jordan Valley Water’s servicearea encompasses much ofthe Salt Lake Valley, including the most rapidly-growing areas in the state. Sources of water include the Provo, Weber and Duchesne rivers, groundwater, and local mountain streams.

Protect what we have• Repair and replacement of existing infrastructure• Watershed and water source protection

Use it wiselyWater conservation – efficient use of a precious resource

Provide for the futureNew water sources and development of new infrastructure

Page 12: Planning for Utahs Water Future

PROTECT WHAT WE HAVE: AGING INFRASTRUCTURE

• Dams• Treatment plants• Power plants• Reservoirs• Thousands of miles of canals,• Pipelines & tunnels

Our infrastructure supports $5.4 trillion in economic activity

Anticipated statewide infrastructure replacement cost through 2060:

$18 BILLION

Page 13: Planning for Utahs Water Future

USE IT WISELYThe state of Utah has set a goal to reduce water consumption by 25% by 2025.

Proposed Conservation Tools:

• Water efficient landscapes –City Ordinances

Park stripsCommercial and residential

• Advanced Metering Infrastructure(AMI)

• Secondary water use metering

• Conservation pricing structure

• Wastewater recycling

PROVIDE FOR THE FUTURENew water supplies and infrastructure will be vital.

Conservation will delay future water development, but expected population growth will eventually drive the need

DESIGN MATTERSContrasting positive spaces (filled with plants) and negative spaces (open gravel or lawn) are the key!

Page 20: Planning for Utahs Water Future

Whenever possible, avoidsprinker boxes, trees or anyobstructions in turf areas.Lowers maintenance andimproves irrigation efficiency.

Negative or “Open” spaces

Positive or “Planted” spaces

PLANTED FRONTAGES DRAW ATTENTION

Gorgeous plantings in the frontages draw attention to businesses- without drawing eyeballs away from street level.

TIP:Dense plantings hide imperfect maintenance!

ELIMINATE GRASS AND/OR OVERHEAD SPRAY IN PARKSTRIPS COMMUNITY-WIDE

Huge benefits to eliminating lawn in parkstrips:

• Reduce negative impact of overspray on asphalt & infrastructure.

• Conserves water.• More attractive, diverse

landscapes.• Creates sense of separation

from roadways.• Waterwise landscapes fare

better during droughts.

MODEL ORDINANCE HIGHLIGHTS:

Colorado Model Ordinance:http://Colorado.gov

• Drip irrigation required in all shrub beds, residential + commercial.

• 4” deep mulch required for all commercial project shrub beds.

• Lawn is not allowed in parkstripsnarrower than 8 feet.

• All systems shall be equipped with an automatic rain shut-off device.

• Minimum width of turf irrigated with sprinklers is 10 feet. Narrower areas must be watered with subsurface drip irrigation.

• Turf limits changed from 33% of total area to 25% in residential settings.

• No new turf in non-residential areas unless it qualifies as a Special Landscape Area or is watered with recycled water.

• Flow sensors are required

California UPDATED Model Ordinance:http://www.water.ca.gov/wateruseefficiency

HOW TO ACHIEVE AN EFFECTIVE WATERWISE LANDSCAPE ORDINANCE

1. Seek input from stakeholders

2. Ordinance must be well written, organized, and comprehensive

3. City councils support, planners require and developers comply

4. Water-efficient landscapes must be attractive and protect property values

5. Caretakers of water-efficient landscapes must water less (ordinance saves water)

6. Most effective when combined with other programs

Page 34: Planning for Utahs Water Future

SAMPLE WATERWISE LANDSCAPE ORDINANCE

• Applicability• All new and expanded development

• Landscape Design• Limited turf• Waterwise plants• Use of mulch

• Irrigation Design• Zonal irrigation• Spray irrigation prohibited on park strips narrower than 8 feet• Irrigation efficiency requirements

• Enforcement• Excessive Water Use
