Summary
Tehama County has no mandate to remove existing lawns, but new and rehabilitated landscaping in the unincorporated county over set size thresholds must meet a turf water budget under the county's Water Efficient Landscape Ordinance.
Portions of landscaped areas in public and private projects such as parks, playgrounds, sports fields, golf courses, or school yards where turf provides a playing surface or serves other recreational purposes are considered recreational areas and may require water in addition to the maximum applied water allowance. A statement shall be included with the landscape design plan, designating recreational areas to be used for such purposes and specifying any needed amount of additional water above the maximum applied water allowance.(3)Estimated Applied Water Use.a.When required the estimated applied water use shall not exceed the maximum applied water allowance.b.When required a calculation of the estimated applied water use shall be submitted with the landscape documentation package.

Full Breakdown
Chapter 17.85, the Water Efficient Landscape Ordinance, applies in the unincorporated area of Tehama County, not inside Red Bluff, Corning or the City of Tehama, to new commercial/industrial landscaping of 2,500+ square feet and new or developer-installed residential landscaping of 2,500+ (multi-family) or 5,000+ square feet (owner-installed) that needs a building permit, plan check or design review. Turf areas count toward the project's Maximum Applied Water Allowance, calculated using the county's 54.74 reference evapotranspiration rate. Turf used as a playing surface in parks, sports fields, golf courses or school yards is classed a 'recreational area' and may draw water beyond that allowance.
Violations & Fines
WELO compliance is checked at building-permit, plan-check or design-review stage for qualifying projects; the code sets no stand-alone turf-replacement fine: noncompliant landscape plans are simply not approved until brought into conformance.
