6-iORM DRAINAGE POLICY ,
GENERAL GUIDELINES
1.Storm water which falls within the development from a 10 -year storm of 24 -hour
duration (approximately 2.4 inches [6.1cm])of which the difference between the
natural runoff and the developed runoff must be retained within the boundaries of
that development (including street areas if within a subdivision).The method of
retention is left up to the developer and requires the approval of the City Engineer.
2.Streets must be constructed to carry the runoff from a 10 -year storm between the
tops of curbs.In cases where the peak flows from the design storm exceed the street
capacity, underground pipes of sufficient size to carry the excess must be installed.
Storm drains, when designed as independent structures, shall accommodate a 10-
year storm.
3.The peak flows from a 100 -year storm must be carried within the cross-section
between finished grade at buildings and at least 6"[15.25cm]below finished floor
elevation.
4.Retention basins are permitted to a MAXIMUM of 3 feet [1m]in depth of
impounded water with MAXIMUM side slopes of 4:1 and must be constructed so
that storm water will dissipate within 36 hours after a storm. A 25% freeboard is
recommended.Pumping, surface percolation, controlled or gravity discharge pipe,
and dry wells are acceptable methods.Dry wells must be registered with ADEQ.
5.Retention areas for which the developer does not establish a private means for its
perpetual maintenance acceptable to the City, must be dedicated to the City.Areas
dedicated to the City must meet the design standards and requirements described
in the "Parks, Open Space, and Rights -of -Way Landscape Standards" provided by
the Parks Department.
6.Existing water courses should be maintained and may be required to be dedicated
to the City as drainageways.Underground street crossings for these water courses
shall be sized for a 10 -year flood.
7.Drainage and retention covenants must be described either on the subdivision plat
or a document to be recorded with the Pinal County Recorders Office.A typical
form is provided as Exhibit "B".
8.Developments south of Old West Highway need not include drainage areas upstream
of Old West Highway provided existing structures are measured and a Q10 is
calculated based upon the structure flowing full with a head equal to the existing
highway pavement grade.
9.Apache Junction participates in the National Flood Insurance Program,Federal
Emergency Management Agency (FEMA).All recognized flood plains and
floodways must be delineated on the plans.
Engineering Guidelines
August 1995 12
PRELIMINARY DRAINAGE REPORT
1.A preliminary drainage report shall be presented with preliminary development
plans. Engineering reviews may not be scheduled without this report which shall be

FLOOD PLAIN MANAGEMENT
The City of Apache Junction having entered into the Flood Insurance Program by
Resolution 79-41 adopted on November 7, 1979, is required to provide adequate flood plain
management and control measures, with effective enforcement, consistent with criteria set
forth by the Federal Emergency Management Agency and Section 1910 of the National
Flood Insurance Program Regulations.This action allows residents of the community to
acquire federally subsidized flood insurance, provides for local flood plain management,
allows for a unified national program for managing flood losses and provides for safer
living conditions.
The following excerpts are taken from the Federal Register:
1.Flood Insurance shall not be sold or renewed unless the community has adopted and
uniformly enforces adequate minimum flood plain management regulations.
2.Requires building sites will be reasonably safe from flooding and constructed to
prevent flotation, collapse or lateral movement, with materials resistant to flood
damage and by methods to minimize flood damage.specific requirements are
provided for mobile homes and trailers.
3.Requires public utilities (includes septic systems) and facilities to be constructed to
minimize flood damage and prevent infiltration of flood waters and systems
contamination.
4.Requires confirmation that alteration or relocation of a water -course (wash) does not
adversely effect upstream and down stream properties.
S.Requires assurances that the flood carrying capacity within altered or relocated
portions of watercourses (washes) are maintained.
6.Requires evacuation plan and alternate vehicular access and escape routes be
provided in Arizona.
7.Requires a Registered professional engineer or architect shall certify that flood
proofing methods are adequate to withstand the flood depths, pressures, velocities,
impact, up -lift forces and other factors associated with the base flood elevation.
8.Requires compliance by new construction or expansion by existing developments or
when repair, reconstruction or improvement equals or exceeds fifty (50%) percent
of the value of the existing development.
9.Requires all encroachments, including fill and new construction be prohibited so as
not to increase the base flood elevation.
Engineering Guidelines
August 1995 17
10.Prohibits the placement of new trailers within regulatory floodways.
11.Variances:
a.Granting a variance is generally limited to lot sizes of less than one half
(1/2 )acre.
b.Variances shall not be issued within a designated floodway if m increase in
flood levels would result.
c.Variances shall only be issued with a showing of good and sufficient cause
and exceptional hardship, providing the variance will not result in increased
flood heights, threats to Public safety, Public expense, nuisances or conflicts.
d.Variances will result in increased premium rates for flood insurance as high
as $25 per $100 of insurance coverage.
12.Suspension of the community flood insurance program will result for failure to adopt
or enforce flood plain management regulations.
In order to comply with Federal Requirements developers and engineers shall provide the
following information:
1.Confirm what flood zone the development is located within.
2.Confirm the base flood (Q100) elevation.
3.Confirm the lowest floor (including basement) is elevated or flood proofed to 1 Foot
[.3m1 above the base flood level (additional 1 foot (.3m1 freeboard flood elevation is
recommended).
4.Confirm watercourses enter and leave areas to be developed in their natural
locations, and that flows or highwater elevations are not increased to the detriment
of upstream and downstream properties.
5.Insure that hydrologic data is presented in accordance with the Storm Drainage
Policy in this guide.
Refer to and comply with provisions of the Flood Plain Management Ordinance, Volume
II - Land Development Code, Chapter 5.

and approval.
2.The developer may need to enter into a maintenance agreement on the form
provided by the City (See Exhibit "D").
3.Landscaping themes already initiated within a quarter -mile [400m1 of the proposed
development should be continued, except as required by the Parks Director.
4.A project's landscaping plant materials shall conform to the list contained in the
"Parks,Open Space,and Rights -of -Way Landscape Standards".The Arizona
Department of Water Resources approved list is included in this list, specifically for
the climate and growing conditions present in this area. These plants are considered
to be of low to moderate water use, which will be beneficial to water conservation
measures.
5.All landscaping that requires water for establishment and future growth shall have
an irrigation system designed and constructed with the type of materials and
maintenance practices as specified in the "Parks, Open Space, and Rights -of -Way
Landscape Standards".
