The model water efficient landscape ordinance of the State of California, as contained in the California Code of Regulations Title 23, Waters, Division 2, Department of Water Resources, Chapter 2.7, Model Water Efficient Landscape Ordinance, and as amended from time to time by the State of California, is hereby adopted by reference as the water efficient landscape ordinance of the Town of Moraga.

Proposed landscape and irrigation plans shall comply with all state requirements of the stormwater control plan (C.3) and the National Pollutant Discharge Elimination System (NPDES) intended to implement stormwater best management practices into the planting, irrigation, and grading plans to minimize runoff and to increase on-site retention and infiltration.

(Ord. No. 298, § 3, 2-9-2022)

A.

Property owners or their building or landscape designers, including anyone requiring a building or planning permit, plan check, or landscape design review from the jurisdiction, who are constructing a new (singlefamily, multi-family, public, institutional, or commercial) project with a landscape area greater than five hundred (500) square feet, or rehabilitating an existing landscape with a total landscape area greater than two thousand five hundred (2,500) square feet, shall comply with Sections 492.6(a)(3)(B) (C), (D), and (G) of the MWELO, including sections related to use of compost and mulch as provided in this section.

B.

The following compost and mulch use requirements that are part of the MWELO are now also included as requirements of this chapter. Other requirements of the MWELO are in effect as adopted by reference in Section 8.178.020.

C.

Property owners or their building or landscape designers that meet the threshold for MWELO compliance outlined in subsection (a) above shall:

1.

Comply with Sections 492.6 (a)(3)(B)(C),(D) and (G) of the MWELO, which requires the submittal of a landscape design plan with a soil preparation, mulch, and amendments section to include the following:

a.

For landscape installations, compost at a rate of a minimum of four cubic yards per one thousand (1,000) square feet of permeable area shall be incorporated to a depth of six inches into the soil. Soils with greater than six percent organic matter in the top six inches of soil are exempt from adding compost and tilling.

b.

For landscape installations, a minimum three-inch layer of mulch shall be applied on all exposed soil surfaces of planting areas except in turf areas, creeping or rooting groundcovers, or direct seeding applications where mulch is contraindicated. To provide habitat for beneficial insects and other wildlife up

to five percent of the landscape area may be left without mulch. Designated insect habitat must be included in the landscape design plan as such.

c.

Organic mulch materials made from recycled or post-consumer materials shall take precedence over inorganic materials or virgin forest products unless the recycled post-consumer organic products are not locally available. Organic mulches are not required where prohibited by local fuel modification plan guidelines or other applicable local ordinances.

2.

The MWELO compliance items listed in this section are not an inclusive list of MWELO requirements; therefore, property owners or their building or landscape designers that meet the threshold for MWELO compliance outlined in Section 14(a) shall consult the full MWELO for all requirements.

D.

If, after the adoption of this ordinance, the California Department of Water Resources, or its successor agency, amends 23 CCR, Division 2, Chapter 2.7, Sections 492.6(a)(3)(B) (C), (D), and (G) of the MWELO requirements in a manner that requires jurisdictions to incorporate the requirements of an updated MWELO in a local ordinance, and the amended requirements include provisions more stringent than those required in this section, the revised requirements of 23 CCR, Division 2, Chapter 2.7 shall be enforced.
