imbedded chain-link fence shall be installed on the disturbance limit line
as identified on the approved site plan for the site. The disturbance limit
boundary shall be established and staked by an Arizona-registered land
surveyor. No disturbance limit fencing shall be located outside of the
surveyor’s staked area. Appropriate warning signs in English and Spanish
shall also be posted at least every 100 linear feet on the required fencing.
The Town Manager or authorized designee shall inspect the fence,

construction prior to the issuance of the building/grading permit for the
site. Such fencing and signage shall be maintained in place throughout the
grading/construction process and shall only be removed after a final
inspection or Certificate of Occupancy has been issued by the Town.
These regulations may be waived by the Town Manager or authorized
designee if 100% of the lot on which the construction activity is permitted
has been graded or disturbed as part of an approved subdivision grading
permit.

a. It is recommended that all proposed non-disturbance areas or
Hillside Protection Easements be located not closer than:
1. Eight feet from any building.
2. Five feet from the outside face of any retaining wall where
the retaining wall is supporting a fill slope.
3. One foot from the “day lighted” top of a maximum one to
one cut slope, the toe of such slope beginning at the bottom
2220339.2

where the retaining wall is supporting a cut slope.
4. Three feet from the outside face of any other wall or fence
or the edge of any fill grading.
5. One foot from the edge of any cut grading.
6. Ten feet from any sewer lateral, or five feet from the edge
of any utility line trench, whichever is greater.
b. If disturbance does take place within a non-disturbance area or
within a Hillside Protection Easement, all construction and grading
activity on the site shall stop, pursuant to a Town-issued stop work
order. The stop work order shall remain effective until the
property owner and the property owner’s authorized
representatives, either jointly or severally, do all of the following:
1. Provides the Town with a revised site plan prepared by an
Arizona-registered land surveyor that accurately depicts the
area and size, in square feet, of the disturbance into the
non-disturbance area(s) or Hillside Protection Easement
area(s).
2. Provides the Town with re-vegetation and irrigation plans
prepared by an Arizona-registered landscape architect for
the non-disturbance or Hillside Protection Easement area(s)
disturbed.
3. Causes the non-disturbance area(s) or Hillside Protection
Easement Area(s) to be re-vegetated and irrigated
according to the submitted and approved re-vegetation and
irrigation plans.

Town Manager or designee, per square foot of disturbance
that occurred within the non-disturbance areas or Hillside
Protection Easements on the property.
10. Columbaria Disturbance Exemptions by Special Use Permit: The
development of columbaria, including any accompanying features such as
walkways, may be exempted from the regulations of this Subsection

landscaping architect, which plan meets the applicable landscaping
regulations of Article VI, Section 6.05 of this Ordinance, is
submitted and approved by the Town Manager or authorized
designee.
11. Pad Elevation and Building Location Certifications: Prior to the
approval of any building stem wall inspection or a pre-slab inspection,
whichever occurs first, the property owner or his/her designee shall
provide the Town with a certification statement that is prepared, stamped
and signed by an Arizona-registered land surveyor, that certifies the
finished floor elevation(s) and the horizontal location of the building. 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.

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

b. A re-vegetation plan shall be submitted with and approved as part
of the landscape plans for the lot or parcel disturbed. 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:

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.

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

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

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.
