Benefits for Property Managers


California Landscape Budgets Program provides you with a FREE water management tool to help you and your customers:

  • Easily track irrigation water use
  • Reduce water bills
  • Improve the health, appearance, and value of landscapes
  • Protect the environment by decreasing urban runoff
  • Maintain compliance with NPDES requirements
  • Identify those accounts that are over-watering for further discussion with the landscape contractor.

Two Simple Questions:

  1. Do you know how much your association paid for water used to irrigate your landscapes during the past month?
  2. Do you know how much your association SHOULD HAVE paid for water used to irrigate your landscapes during the past month?

The Landscape Performance Certification Program gives you the right answers to both these questions, month after month, at NO COST to you or your customers.

How It Works:

The California Landscape Budgets Program creates a loop of accountability between the HOA Board, the Property Manager, and the Landscape Contractor.  A customized water budget is created for each irrigation meter using:

1. Data from Your Site

We take certain basic information from your property, such as contact information, location, and irrigated landscape area for each dedicated irrigation water meter, and store this information on our secure webpage for your viewing only.

2. Consumption Data from Your Water Retailer

Every month, your water retailer sends us a download of the consumption for all your irrigation accounts.

3. Data from Weather Stations

We obtain a daily data download from the (California Irrigation Management Information System) Spatial CIMIS network of stations.  We use data from a combination of local weather stations closer to your meter location.  Contained within this information is an “index” number known as the Evapotranspiration* (ETo).

*Evapotranspiration: The combined process of both evaporation from the soil and transpiration through plant foliage.

4. Putting It All Together

We then create a water budget for the site.  This budget is an estimate of the monthly water requirements for a specific irrigation meter, and is calculated using these formulas:
(Budget for Turf) + (Budget for Shrubs & other) = Meter Budget

Calculating Budget for Turf (in CCFs, or billing units):
(ETo x Kc* x (Turf irrigated area in acres) x 36.3)/IE

ETo: daily evapotranspiration rate provided by Spatial CIMIS network of stations.
Kc* for turf (warm season grass): varies depending on the growing season, for example January is 0.58 and July is 0.718
IE: Irrigation Efficiency is 0.8 or 80%

Calculating Budget for Shrubs and other (in CCFs, billing units):
(ETo x Kc** x (non-turf irrigated area in acres) x 36.3)/IE

Kc** for shrubs and others is 0.5
