An applicant for a building permit for a new single family residence or non-residential project subject to this chapter where the aggregate landscaped area of the project is greater than 500 square feet but less than 2,500 square feet shall, as a condition of obtaining a building permit, submit a Landscape Documentation Package or a landscape plan compliant with the Prescriptive Compliance Option in this chapter. The application process shall include establishing a MAWA for the project.
(a) Except as otherwise provided, an applicant for a building permit for a project described in section 86.703(a) shall submit a Landscape Documentation Package with the permit application.

(c) The Landscape Documentation Package required by subsection (a) shall contain the following:
(1) A project description that includes the date, project applicant, project location identified by address or parcel/lot number, total landscaped area in square feet, project type (e.g., new, modified, public, private, cemetery), water supply type (e.g., potable, recycled, well, graywater), checklist of all documents included in the Landscape Documentation Package, and project contacts for the applicant and property owner if different.
(2) A soil management report that complies with section 86.708 that analyzes soil composition within each landscaped area of the project.
(3) A landscaping and irrigation plan that complies with section 86.709 that describes the landscaping and irrigation for the project.
(4) A water efficient landscape worksheet that complies with section 86.711 that calculates the MAWA and the ETWU for the project.
(5) A grading design plan that complies with section 86.710 that describes the grading of the project.
(6) Evidence of compliance with section 86.718 for projects with model homes.
(a) The soil management report shall contain the following information:
(1) An analysis completed by a properly certified or accredited laboratory using accepted industry protocol. The analysis shall be of the soil for the proposed landscaped areas of the project that includes information about the soil texture, soil infiltration rate, pH, total soluble salts, sodium, and percent organic matter.
(2) Recommendations about soil amendments that may be necessary to foster plant growth and plant survival in the landscaped area using efficient irrigation techniques. Locally produced, non-petroleum based soil amendments shall be preferred.
(b) When a project involves mass grading of a site the applicant shall submit a soil management report that complies with subsection (a) above with the Certificate of Completion required by section 86.725.
(c) In projects with multiple landscape installations (i.e., production home developments) a soil sampling rate of 1 in 7 lots or approximately 15 percent will satisfy this requirement. Large landscape projects shall sample at a rate equivalent to 1 in 7 lots. Mass grading projects shall provide a soil sampling test for every 25,000 square feet of area graded.
