Pad elevations and building locations must be accurate to 1/10th of a foot as compared to the approved site plan or an amended site plan. The requirements in this subsection may be waived at the discretion of the Town Engineer. 12. Stabilization of Slopes: Slope stabilization is required as set forth in the Town’s most recently adopted version of the International Building Code, as amended. 13. Pre-Grading: A grading or building permit shall not be conditioned on altering, modifying or not utilizing existing grading, if the existing grading work was completed in conformance with valid permits, and does not present a threat or danger to the proposed development or neighboring properties. This provision does not prevent the Town Engineer from requiring necessary documentation of site suitability to assure soil stability, compaction, and other geotechnical purposes. 14. Restoration of Graded Surfaces: a. Vegetation shall be reestablished on all exposed fill slopes, cut slopes, utility lines, driveway(s), and graded surfaces, except for cosmetic landscaping abutting buildings in accordance with the standards established in Article VI of this Ordinance.

The re- vegetation process shall be completed prior to the final approval by the Town Manager or authorized designee, unless a specific exemption is granted by the Town Manager or authorized designee. Grading and other improvements for drainage and erosion control purposes shall also be completed and re- vegetated/landscaped prior to final inspection. 15. Dust Control: During all grading, and until re-vegetation or site restoration is completed, dust should be minimized by application of approved dust control methods. C. Exemptions: 1. Lots used for governmental purposes and owned by utility companies that are regulated by the Arizona Corporation Commission, and lots owned by other political subdivisions of the State or Federal government, are exempt from the hillside disturbance limitations of Sections 5.02 and 5.04. 2. A 20’ wide band of primary driveway access (measured from the back of curb to the nearest point of intersection with any portion of the house, the garage door or a carport or covered driveway, if any) is excluded from the hillside disturbance limitations. 3. A 10’ wide utility trench exemption may be allowed, subject to written confirmation of the requirement from the utility company stating that the trench must be outside the driveway access exemption. Such exempted area must be re-vegetated in accordance with subsection 5.02(B)(14). 4. Single-Family Residential lots zoned R1-6, R1-6A, R1-8, R1-8A, R1-10 and R1-10A shall be 100% disturbable and exempt from the hillside disturbance limitations. 5. Non-residential property in Commercial or Industrial zoning districts shall be 100% disturbable and exempt from the hillside disturbance limitations. SECTION 3. The Subdivision Ordinance, Article 5 (Grading Standards), Subsection 5.04.A (Purpose; Methodology), is hereby amended as follows: A. Purpose; Methodology. The purpose of these hillside regulations is to limit the amount of hillside disturbance within each subdivision. The amount of hillside area that may be disturbed shall be based on the severity of the slope. Hillside areas shall mean any area having slopes equal to or greater than 10 20%, as measured from a topographical contour map prepared and stamped by an Arizona-registered land surveyor. The Town requires the submission of topographic contour maps having contour intervals not greater than two feet and 2220339.2 7 at a scale not smaller than 1” = 20’ for sites less than 10 acres. Sites 10 to 100 acres may utilize contour intervals not greater than five feet at a scale not smaller than 1” = 50’. Sites over 100 acres may utilize contour intervals not greater than five feet at a scale not smaller than 1” = 100’. Individual non-contiguous areas of hillside or non-hillside that are less than 500 square feet that are located within larger areas non-hillside or hillside, respectively, may be included with the larger area of non-hillside or hillside that surrounds it. Whether a subdivider chooses the Lot-by-Lot Hillside Protection Option or the Hillside Transfer and Protection Option as set forth in SubSections 5.04.G.1 and 5.04.G.2, respectively, the actual square footage of disturbance permitted within one slope interval may be transferred into areas having lesser degree of slope. The percent of slope shall be determined by the spacing between the contours lines as shown on the preliminary plat. Following are the land disturbance allowance of slope interval areas of 500 square feet or more: Percent of Slope Preservation Requirement (%) Disturbance Allowance (%) <10 0 100 10 - <20 70 30 20 - <30 80 20 30 and more 90 10 PERCENT OF SLOPE PRESERVATION REQUIREMENT (%) DISTURBANCE ALLOWANCE (%) 0 – 20% 0 100 % 20% + 60% 40% SECTION 4. The Subdivision Ordinance, Article 5 (Grading Standards), Subsection 5.04.B (Exemption; Calculations), is hereby amended by adding a new Subsection, 504.B.1.c, to read as follows: c. All lots and uses deemed exempt under Subsection 5.02.C of this Article. SECTION 5. The Subdivision Ordinance, Article 5 (Grading Standards), Section 5.04 (Hillside Disturbance), is hereby amended by deleting the Illustration of Preservation Requirement, in its entirety. SECTION 6. If any section, subsection, sentence, clause, phrase or portion of this Ordinance is for any reason to be held invalid or unconstitutional by the decision of any court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of this Ordinance. SECTION 7. The Mayor, the Town Manager, the Town Clerk and the Town Attorney are hereby authorized and directed to execute all documents and take all steps necessary to carry out the purpose and intent of this Ordinance.
