WHERE & HOW WE BUILD MATTERS FOR WATER SAVINGS

1 SMALLER LOT SINGLE FAMILY DEVELOPMENT

Studies found 10 to 60% water savings with increased density

• f single-family residences.

2 MULTI FAMILY DEVELOPMENT

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.

3 EFFICIENT LANDSCAPING AND IRRIGATION

Landscape code requirements can reduce outdoor water use by 35-50%.

4 INDOOR WATER USE

Water efficient fixtures and appliances, building and plumbing codes can have significant savings.

• 1. Reduce the amount of water needed for irrigation by enhancing soil

conditions, appropriate plant types and landscape design.

• 2. Decrease water waste by improving site-specific water efficiency

Enhancing soil conditions, appropriate plant types and landscape design. :

Improving site-specific water efficiency through irrigation system design, best practices and technology.

Water Efficient Irrigation Systems

• Water-use management plan or water

budget.

• Hydrozones that group similar water

demands by irrigation zone.

• Non-potable water source.
• Separate irrigation meters.
• Irrigation system design.
• Irrigation shutoff valve.
• Efficient emitters.
• Master valves and flow sensors.
• Smart irrigation system controllers.
• Rain sensors.
• Soil moisture sensors.
• Overhead (spray) irrigation.

– Allowable only where sufficient width exists to prevent waste. – Pop-up height consistent with mature height of plants being watered – minimum of 6 inches. – Pop-up spray heads equipped with internal check valves, internal pressure regulations, and matched precipitation rate spray and rotary nozzle. – Rotors equipped with internal check valves and pressure regulations are more efficient than spray heads. – Head-to-head coverage.

• Drip systems.

– Point source drip or subsurface drip irrigation for all trees, shrubs, perennials and annuals. – Internal check valves at each drip emitter and for subsurface drip systems. – Subsurface drip irrigation may be used for turf or grass areas. – Bubblers may be substituted for drip emitters.

Alternative and/or Complement to a Landscape Ordinance

• TIME OF DAY/SEASON: Outdoor irrigation is prohibited

between 11 AM to 7 PM from May through September of each year.

• WATER WASTE: Vehicle washing is only allowed with the use
• f a shut-off hose nozzle.
• WATER WASTE: An outdoor irrigation system may not be
• perated while a leak from it exists.
• WATER WASTE: All swimming pools, hot tubs and spas must

be covered to prevent evaporation when not in use. Swimming pools may only be emptied once per year.

• WATER WASTE: Water system leaks from private water lines

shall be repaired by the owner or property manager within fifteen (15) days of initial notification by the County or the

• wner’s knowledge of the leak. Proof of repair shall be

provided to the County upon completion of the repair when such notification is requested.

MECHANISM OPTION C | WATER CONSERVATION ORDINANCE

Alternative and/or Complement to a Landscape Ordinance

• TYPE OF PLANT MATERIAL: Planting sod or grass seed that

contains Kentucky bluegrass is not permitted

• IRRIGATION: Drip system requirements.
• HOAs: Must include conservation requirements in

convenants and file with County.

• WATER SUPPLY BUDGET: Set water budget lower than SEO

well standard.

• INDOOR: Requires water efficient plumbing fixtures.
• METERING: Requires self reporting on well meters.

Water Efficiency Programs & Water-Land Use Nexus Recommendations (2015)

• 1. Common landscape and

irrigation regulations.

• 2. Contractor certification

program.

• 3. Outreach and education

program.

GENERAL INTENT AND BENEFITS

 Promote the value and benefits of landscapes while recognizing

need for efficient use of water outdoors and prevent waste

 Focus on new construction/rehabilitated projects  Promote standardization of best management practices across

the SMWSA area by providers that voluntarily elect to adopt

 Encourage efficient use of water through use of a maximum

landscape irrigation water budget

 Encourage local agencies to designate necessary authority to

implement and enforce provisions

SOIL AMENDMENT AND PREPARATION STANDARDS

TOP 10 RECOMMENDATIONS

38

LANDSCAPE CRITERIA

• Soil amendment & preparation
• Mulching

IRRIGATION SYSTEM CRITERIA

• Master shut-off valve & flow sensors
• Pressure-regulating devices
• Dedicated non-res landscape meters
• Irrigation system design specs
• Weather/soil moisture sensors
• Sprinkler spacing
• Emission device specs

HYDROZONE REQUIREMENTS

CONSIDERATIONS FOR LOCAL UTILITIES

39

• Compare Top 10 to existing requirements

▪Consider updating standards/regs ▪Update materials that recommend but don’t require

regulatory changes

• Identify potential departmental

roles/responsibilities for implementing - reviewing plans, audits reports, etc.

• Determine local enforcement mechanisms
• Consider a pilot phase

What do most of f us do when we hear something that’s too good to believe?

Frederick Landscaping Updates

Current status

• 20% of all Business Light Industrial and Industrial sites

must be landscaped including

• Turf (irrigated)
• Trees – site and street (irrigated)
• Shrubs (irrigated)
• FLOWERS!?! (irrigated)
• Why don’t rocks count as landscaping? – Or - If I

mow the weeds, does that count?

• Parking lot landscaping

Frederick Landscaping Updates

Desired status

• Landscaping to improve the look of business

parks

• Businesses shouldn’t have to take out a

second mortgage to finance watering the required landscaping

• Straightforward rules that small business
• wners can understand and maintain
