The web's mother lode of free irrigation information!
Below are spreadsheets for various purposes related to irrigation.
This spreadsheet creates an irrigation schedule and does all the water useage calculations required when designing landscape and irrigation in areas under the jurisdiction of the Los Angeles County Planning Department, California. Print out each page of the spreadsheet and include them with your plans when submitting to the county for review, approval, or permits. This spreadsheet is intended for design professionals, assumes you have a basic understanding of irrigation design, and contains only minimal instructions for use.
This is a chart of "official" monthly ETo values for various areas of Los Angeles County. It was prepared by LA County and is used with the spreadsheet above.
