IrvineRanch Water District has been a pioneer in establishing site-specific water budgets for its customers. However,establishing a water budget requires certain data, and if landscaping is at the site, this means obtaining thesquare footage of the irrigated area. On-site measurements are time-consuming and not always cost-effective.Aerial photography can be more cost-effective per site, but still can be cost-prohibitive to obtain. This paper discusses a cost-effective methodology for sizing landscape areas researched by IRWD that is accurate in determiningwater budgets for single-family residences. This methodology can be adopted by any water agency. Its keyrequirements are as follows:ensure customer confidence in the allocation byincluding landscape areas that fall within 1 standard deviation of mean, not median lot size;develop allocations that truly promote efficient irrigation practices byincluding landscape areas that fall within 1 standard deviation of mean, not 2 standard deviationsfrom mean; and,develop a method that can be used universally in any community for a nominal cost that does not require individual measurements, only lot sizes required. Lot size informationtypically is available from property tax assessors or real estate data. Includes 2 references, tables.
