The prescriptive requirements may be used as a compliance option to the model water efficient landscape ordinance. Compliance with the following items is mandatory and must be documented on a landscape plan in order to use the prescriptive compliance option:
A. Submit a landscape documentation package which includes the following elements:
1. Date;
2. Project applicant;
3. Project address (if available, parcel and/or lot number(s));
4. Total landscape area (square feet), including a breakdown of turf and plant material;
5. Project type (e.g., new, rehabilitated, public, private, cemetery, homeowner installed);
6. Water supply type (e.g., potable, recycled, well) and identify the local retail water purveyor if the applicant is not served by a private well;
7. Contact information for the project applicant and property owner;
8. Applicant signature and date with statement:
I agree to comply with the requirements of the prescriptive compliance option to the MWELO.
B. Incorporate compost: At a rate of at least four (4) cubic yards per one thousand (1,000) square feet to a depth of six inches (6") into landscape area (unless contraindicated by a soil test).
C. Plant material must comply with all of the following:
1. For residential areas, install climate adapted plants that require occasional, little or no summer water (average WUCOLS plant factor 0.3) for seventy five percent (75%) of the plant area excluding edibles and areas using recycled water;
2. For nonresidential areas, install climate adapted plants that require occasional, little or no summer water (average WUCOLS plant factor 0.3) for one hundred percent (100%) of the plant area excluding edibles and areas using recycled water; and
3. A minimum three inch (3") layer of mulch must be applied on all exposed soil surfaces of planting areas except in turf areas, creeping or rooting ground covers, or direct seeding applications where mulch is contraindicated.
D. Turf must comply with all of the following:
1. Turf must not exceed twenty five percent (25%) of the landscape area in residential areas, and no turf is permitted in nonresidential areas to comply with the prescriptive compliance option;
2. Turf must not be planted on sloped areas which exceed a slope of one foot (1') vertical elevation change for every four feet (4') of horizontal length;
3. Turf is prohibited in parkways less than ten feet (10') wide, unless the parkway is adjacent to a parking strip and used to enter and exit vehicles. Any turf in parkways must be irrigated by subsurface irrigation or by other technology that creates no overspray or runoff.
E. Irrigation systems must comply with the following:
1. Automatic irrigation controllers are required and must use evapotranspiration or soil moisture sensor data.
2. Irrigation controllers must be of a type which does not lose programming data in the event the primary power source is interrupted.
3. Pressure regulators must be installed on the irrigation system to ensure the dynamic pressure of the system is within the manufacturer's recommended pressure range.
4. Manual shutoff valves (such as a gate valve, ball valve, or butterfly valve) must be installed as close as possible to the point of connection of the water supply.
5. All irrigation emission devices must meet the requirements set in the ANSI standard, ASABE/ICC 802-2014, "Landscape Irrigation Sprinkler And Emitter Standard". All sprinkler heads installed in the landscape must document a distribution uniformity low quarter of 0.65 or higher using the protocol defined in ASABE/ICC 802-2014.
F. At the time of final inspection: The permit applicant must provide the owner of the property with a certificate of completion, certificate of installation, irrigation schedule and a schedule of landscape and irrigation maintenance. (Ord. 1515, 12-15-2015)
