Seminar Description:
In 2019, the California Center for Urban Horticulture, UC Davis, created the SmartLandscape initiative to determine if low water use landscapes could be designed, installed, managed, and maintained to meet the Model Water Efficient Landscape Ordinance (MWELO). For MWELO performance approach compliance, Maximum Applied Water Allowance (MAWA) is greater than the Estimated Water Use (ETWU).?While MWELO compliance is determined by estimating water use for a specific landscape area, the SmartLandscape initiative will validate compliance by measuring Actual Water Applied (AWA). SmartLawn demonstration plots (cool and warm season turf) and SmartScape I and II were designed and planted irrigated by sub-surface and surface irrigation dispersion and smart controller technology.   



This presentation will provide data confirming MWELO compliance of SmartLawn and SmartScape landscapes by utilizing AWA versus ETWU and how AWA data was utilized to confirm calculate the actual plant factors for SmartLawn and SmartScape landscapes.  Comparison of AWA plant factors will also be compared to the plant factors assigned by WUCOLS IV.  Measuring and employing AWA data is the definitive method for confirming MWELO compliance versus using ETWU for both SmartLawn and SmartScape demonstration landscapes. 




Learning Objectives:
1. Low water use landscapes, warm season turfgrass and mixed shrub and trees, can be designed, installed, managed, and maintained to meet the Model Water Efficient Landscape Ordinance at UC Davis.
2. Measuring and using actual water applied data provides definitive confirmation for MWELO compliance versus using ETWU.
3 Landscape irrigation replacement strategy for MWELO compliance is challenging.
