§ 10-1-1 PURPOSE OF ENGINEERING STANDARDS.
The purpose of the Engineering Standards ("this Chapter" or "these Standards") is to provide both
general information and specific design standards to inform developers and their designers of the planning
and designing of public and private infrastructure within the City of Apache Junction. Design concepts and
1
specific technical data are outlined, but are not intended to supersede sound engineering judgment.All
plans are to be prepared with these concepts in mind and will be reviewed accordingly.No attempt has
been made in these standards to establish a complete set of design criteria; however, certain standards must
be followed to provide consistency for the sake of maintenance, repair or replacement.
§ 10-1-2 SECTIONS.
(A)Generally.This Chapter is divided into individual sections and specially designated areas, which
cover specific elements of the design and development review process.It begins with general information
followed by specific technical details.Staff updates will be published and made available periodically on
an as needed basis.The city engineer may provide a "Memorandum of Clarification" to portions of the
standards on an as -required basis.Clarifications will posted on the city website and at the City Clerk's
Office.
(B)Specially designated areas.The specially designated areas are included as individual separate
elements of this Chapter and are as follows:
(1)Downtown Area Vol. II, Appendix 10-A).The physical limits of the Downtown
Area are shown on Apache Junction Standard Detail AJ-12.1.
(2)Rural Area (A.J.C.C., Vol. II, Appendix 10-B).The physical limits of the Rural Area are
shown on Apache Junction Standard Detail AJ-12.1.
(3)Lost Dutchman Heights (A.J.C.C.,Vol. II, Appendix 10-C).The physical limits of Lost
Dutchman Heights are shown on Apache Junction Standard Detail AJ-12.1.
§ 10-1-3 INTENT.
These Engineering Standards are intended to be used in conjunction with the specifications of the land
development, subdivision, zoning, floodplain, grading, landscaping and other appropriate ordinances of the
city, and such other agencies as may have jurisdiction.
§ 10-1-4 GENERAL INFORMATION.
(A)All development within the city shall comply with all requirements of the city codes, ordinances,
procedures, rules, regulations, guides and manuals.Copies of these documents, with revisions, are on file
in the Apache Junction City Clerk's office.Preliminary and final design plans shall be prepared in
accordance with these standards.
(B)All construction of public infrastructure shall be in accordance with the approved plans, the latest
City of Apache Junction Engineering Standards (this Chapter), the Apache Junction Standard Details set
forth in A.J.C.C., Vol. II, Appendix 10-D to this Chapter, the current Uniform Standard Details and

Arizona Department of Transportation ("ADOT"), American Water Works Association ("AWWA"),
American Association of State Highway and Transportation Officials ("AASHTO"), American Public
Works Association ("APWA"), Arizona Department of Environmental Quality ("ADEQ") and by the city
as follows:
2
(1)Conceptual site/improvement plans.
(a)A developer may prepare and submit a conceptual site/improvement plan for purposes
of discussion with the development services department and the public works department. The Preliminary
Design Review process will provide general directions, comments and requirements, which may aid the
developer in the production of his or her final plans.City staff will reserve specific directions, comments
and requirements at the time of formal plans submission.
(b)In certain cases, such as projects with access off major thoroughfares, or projects
located in areas of major drainage concerns/problems, a conceptual plan may be required in order for the
development services department and the public works department to assess concerns and provide
recommendations.
(2)Horizontal and vertical control.
(a)The developer's engineer shall prepare plans in conjunction with established and
verified horizontal control available adjacent to the site, and with vertical datum as provided by the city.
(b)Benchmarks shall be clearly indicated on the cover sheet, and temporary benchmarks
shall be clearly indicated on each plan/profile sheet of the improvement plans.All plans shall reference a
minimum of two city benchmarks for horizontal control and a minimum of one benchmark for vertical
control. Horizontal and vertical controls used for the project shall be identified on the cover sheet and shall
include the basis of bearings, and the city benchmark numbers, description and latest elevation.The
benchmarks shall be verified by the construction contractor during construction.
(c)All CAD drawings shall be referenced to a minimum of two known Maricopa County
Department of Transportation ("MCDOT") Geodetic Densification and Cadastral Survey ("GDACS")

(d)In the case of large projects where the improvements cannot be shown on one (1) plan
sheet, the plans must include a general Master Utility Plan for the development.This Master Utility Plan
shall appear on one (1) sheet and be included with the improvement plan set. The Master Utility Plan shall
include proposed street light locations.
(6)Soils report.The developer shall provide a soils investigation report for each project. Areas
of unsuitable soil and areas that have large shrink and swell potential, as well as areas of subsidence or
fissures, will require special treatment during project construction.The developer's engineer shall note
these areas and special treatment requirements from the soils report on the plans.The report shall
investigate soil conditions for structural thickness for all streets, percolation rates for dry wells or retention
basins, building foundation allowable loads, and retaining wall allowable loads.
(7)Plan review.
(a)Once the plans for the development have been prepared, they shall be submitted to the
development services department with the appropriate development and review fees. Once submitted, they
will be distributed to the appropriate city departments and Fire District for their review and comment. These

§ 10-1-5 POLICIES RELATED TO DEVELOPMENT IMPROVEMENTS.
The following sections outline the city's policies related to various improvements associated with the
development process.They are by nature general in scope.Reference should be made to the appropriate
sections within the balance of these standards for specific details.
(A)Street improvement policy.
(1)All developments within the city shall provide an interior street system adequate to ensure
that all parcels and/or facilities within the development shall have reasonable access to the balance of the
public street system.Further, they shall provide access into the development for public service and/or
emergency operations.Such facilities shall be of such width and structural strength as to provide safe and
unrestricted access.
(2)In single-family developments it is the intent of the city that the street system be designed in
conformance with current street classifications.There shall be minimal direct access to the collectors,
secondary streets, and extremely limited access to the arterials.
(3)When the development occurs adjacent to a boundary street, it is the city's policy that it shall
be the responsibility of the developer to install improvements along their frontage to the ultimate grade and
alignment for that boundary street. This may include removal and replacement of the existing street surface
to the centerline if that structure is inadequate to meet the current design standards.Concrete curb and
gutter, concrete sidewalk, street lighting, landscaping, irrigation and burial of overhead utilities will be
required, at the sole or substantial expense of the developer.
(B)Storm drainage policy.
(1)It is the city's policy that all developments within the city shall provide sufficient
retention/detention so as to minimize the adverse impact of that development on its downstream neighbors.
To that end, all development shall provide sufficient on -site retention/detention to contain, at the least, the
runoff generated by storm event falling on that property (see A.J.C.C., Vol. II, § 10-4-2(A)(1) and (2)).
Such retention/detention facilities shall be separate and distinct tracts or drainage easements within the
development and shall be planned for accordingly.
(2)Further, it is the city's policy that all developments shall provide adequate drainage facilities
so as to convey runoff, generated both on and off the project, around or through the project in such a manner
as to ensure that the structures will be free from flooding and that there is reasonable access for emergency
and public service vehicles.The developer shall install storm sewers, channels and/or other physical
improvements necessary to achieve this result.
(3)The Drainage Design Manual for Maricopa County;Volume I,Hydrology,shall be used to
determine peak discharge volumes for design purposes, and Volume II,Hydraulics is to be utilized as a
basis for design guidance and criteria.
6
(4)When washes cross a property, an erosion ha7ard setback from the edges of the wash(es)
will be determined by the development services department and no buildings will be constructed within the
setback without industry acceptable erosion hazard setback mitigation techniques and structures.
(C)Water line extension policy.It is the city's policy that all development within the city shall have
an adequate and secure source of potable water.Therefore, unless specifically excepted in writing by the
Apache Junction Water Utilities Community Facilities District ("WUCFD") or the Apache Junction Water
District ("AJWD"), all developments within the city shall be serviced by AJWD or Arizona Water
Company.Further, the developer shall extend the system to and through the development as necessary to
ensure adequate supply to the development. If deemed necessary and appropriate, the developer shall extend
the water distribution system to the extremities of the project so as to ensure that more distant potential
users shall have reasonable access to the potable water source.
(D)Sewer line extension policy.It is the city's policy that, unless specifically excepted in writing by
the Superstition Mountains Community Facilities District No. 1 ("SMCFD"), all developments within the
city shall provide for the discharge of domestic and other liquid waste into the sewage system provided by
SMCFD. All developers shall be required to extend to and through their project a sewage collection system
of a size sufficient to dispose of these wastes to the SMCFD's system.When deemed appropriate and
necessary, the developer shall extend the main trunk and/or collector lines to the upstream extremities of
the project so as to provide reasonable access for potential upstream users to the SMCFD's sewage system.
Owners of developments outside the city limis but within the CAG 208 Plan boundaries must annex into
the city and enter into a development agreement to do so which is binding to successors in interest.
(E)Site development policy.It is the city's policy that all development within the city shall be
designed and constructed in such manner as to provide a safe and pleasant environment for the current and
future citizens of Apache Junction.To that end, the appropriate standards have been established for site
development, to include:public and/or private access for general and special uses; water and sewage
systems; on -site and off -site drainage; irrigation; landscaping; storm retention; street lighting, traffic control
and public utilities as may be required. The structures themselves are to be constructed in accordance with
the Subdivision Regulations (A.J.C.C. Vol. II, Chapter 2) and/or Zoning Ordinance (A.J.C.C., Vol. II,
Chapter 1), the current adopted International Building Code, Standard Specifications, and these standards,
as appropriate.
(F)Order of precedence.It is not intended by these standards to repeal, abrogate, annul or in any
way impair or interfere with existing provisions of other laws or ordinances except those specifically
repealed with private agreement, or with restrictive covenants running with the land to which the city is a
party.Where these standards impose a greater restriction on land, buildings or structures than is imposed
or required by such existing provisions of law, ordinance, contract or deed, the provisions of these standards
shall prevail.
(G)Definitions and abbreviations.The words, abbreviations or phrases used in these standards may
be found in the Maricopa Association of Governments Uniform Standard Specifications for Public Works
Construction (Standard Specifications) and Uniform Standard Details for Public Works Construction
(Standard Details). All other words or phrases shall be per the generally accepted meaning of the English
language.

§ 10-3-4 DESIGN STANDARDS.
Street design will be in accordance with the following criteria, subject to the approval of the city
engineer.Geometric design standards not specifically included in this standard will conform to the latest
A Policy on Geometric Design of Highways and Streets,published by the AASHTO.
(A)Street right-of-way requirements.
(1)The right-of-way requirements shall be as shown in Apache Junction Standard Details AJ-
20.1 through AJ-20.8.
(2)Right-of-way widths in excess of the standard widths may be required in special
circumstances such as when:
(a)cut or fill slopes cannot be confined within the standard width;
(b)minimum sight distance lines on horizontal curves are not within standards;
(c)minimum sight distances at intersections are not within the standards; and
40
(d)auxiliary lanes are to be provided.
(B)Intersections.Although all intersections share certain common elements, they are not subject to
generalized treatment.
(1)Minimize conflict.To minimize conflicts and provide for anticipated traffic movements,
each intersection must be evaluated with regard to its individual characteristics, and designed based on the
following factors:
(a)traffic factors such as capacities,turning movements,vehicle size and operating
characteristics, vehicle speed, pedestrian movements, transit operations and accident history;
(b)physical factors such as topography, existing conditions, channelization requirements;
and
(c)human factors such as driving habits, reaction to surprises, decision and reaction time,
and natural paths of movement.
(2)Angle of intersection.A right-angle intersection provides the shortest crossing distance for
intersecting traffic streams.It also provides the most favorable condition for drivers to view and judge the
relative position and speed of intersecting vehicles. Where special conditions exist, intersection angles may
diverge from a right angle with approval of the city engineer.
(3)Alignment and profile.Intersections occurring on horizontal or crest vertical curves are
undesirable. When there is latitude in the selection of intersection locations, vertical or horizontal curvature
should be avoided.A line or grade change is frequently warranted when major intersections are involved.
If a curve is unavoidable, it should be as flat as site conditions permit.Where the grade of the through
roadway is steep, flattening through the intersections is mandatory.
(4)Intersection sight visibility.
(a)Sight visibility triangles.Clear lines of sight will be maintained along all streets, alleys
and driveways to assure the safety of motorists and pedestrians.
(1))Lines of sight.Lines of sight will not be obscured between 24 inches and 6 feet through
a triangular area adjacent to a driveway, an alley or a street, where such access ways intersect with another
street in a 1 -configuration.The sight visibility triangle, or sight triangle, consists of three sides that are
formed by two intersecting access ways and a line connecting the two.
(C)Sight distance.
(1)Adequate sight distance shall be provided at all intersections, alleys and driveways.
(2)The determination of whether an object constitutes a sight obstruction shall consider both
the horizontal and vertical alignment of both intersecting roadways, as well as the height and position of
the object.
41
(3)The sight distance required varies according to traffic speeds on the through road. A designer
shall provide the sight distance based on the latest AASHTO Policy on Geometric Design of Highways and
Streets and submit it with the plans.
(D)Street slopes.
(1)Typical street cross -slope.Undivided streets should have a normal crown that is a two-way
cross -slope with the cross-section high point on the street centerline.Divided streets should have cross-
slope on each pavement section. The high point of each slope on each pavement section shall occur on the
edge of the pavement nearest to the median.Existing conditions may cause cross -slope requirements to
vary.The nominal cross -slope is 2%, with a maximum cross -slope of 3% and a minimum cross -slope of
1%. Any deviation from the nominal cross -slope shall be approved by the city engineer.
(2)Cross -slopes in street dip sections.While dip sections are discouraged, where storm
drainage runoff flows must cross the street, dip sections are needed and must be approved by the city
engineer.The pavements through the dip section should have a 1 -way slope (no crown), curbing and
medians must not be raised, and cut-off walls shall be installed in accordance with MAG Standard Detail
552.Transitions back to normal street cross -slopes will be needed at both ends of the dip section.
(3)Existing cross -slope.See A.J.C.C., Vol. II, § 10-3-6(D) for street widening standards.
(4)Longitudinal slope.
(a)The minimum street and gutter slope for public streets is 0.0032 feet/feet (0.32%).
Special approval by the city engineer is required for slopes less than the minimum.
(b)Projects that have any area with less than the approved minimum gutter slope shall
provide construction staking on the actual gutter alignment (not offset) at a spacing not to exceed 25 feet
and have the grades checked by a city engineering inspector immediately preceding the concrete pour.
(c)Grade breaks and grade changes shall be clearly noted and stationed on the grading and
drainage plan and the profile views.
(d)Projects with longitudinal slopes less than 0.32% shall have the gutter lines water -tested
in the presence of and to the satisfaction of the city's inspector.
(5)Vertical curves.Roadways with a longitudinal grade break or grade change of greater than
1.5% shall be required to design and construct a vertical curve along that section of roadway.Vertical
curves shall be designed, at a minimum, per the most current AASHTO standards.
(6)Superelevation.Although the superelevation of roadways is discouraged,unusual
circumstances may require the use of superelevation.The city engineer must approve the use and design
of superelevated roadways.Roadway drainage must be considered in superelevated conditions.
(7)Undulating roadways.Roadways shall be designed to eliminate undulations.In the case
where an existing paved roadway undulates, it shall be removed full width and reconstructed to a new grade
acceptable to the city engineer and the entire cost paid for by the developer.
(8)Side slopes.Side slopes should be designed for functional effectiveness and ease of
maintenance.
42
(a)For areas more than 10 feet from back of curb, slopes of 4:1 or flatter shall be provided.
(b)Steeper slopes may be approved in areas more than 30 feet from back of curb when
soils are not highly susceptible to erosion, or when a cut is not more than 4 feet vertical. Cuts or fills greater
than four feet vertically shall be approved by the city engineer.
(E)Pavement tapers.
(1)Projects are required to provide sufficient pavement tapers at all necessary locations (such
as the beginning or end of a project) to properly transition traffic flow between varying widths of existing
and new pavement.
(2)The pavement section for tapers shall be per these standards.See Table 10-3.1 under
A.J.C.C., Vol. II, § 10-3-5 below.
(3)Pavement tapers shall be constructed with a thickened edge per MAG Standard Detail 201,
Type "B."
(4)Taper length formulas:Taper length for merging traffic situations are calculated by the
following formulas:
(a)When the design speed is 40 mph or less:TL =WxS2
60
(b)When the design speed is 45 mph or greater:TL = WxS
where:
TL =Taper length in feet
S =Design speed in miles per hour.The design speed is 5 mph over the posted speed limit.
W =Width of the offset between the edge of the travel lane and the edge of the lane after the taper
(5)Taper length for non -merging traffic situation (such as where pavement widens with traffic)
is normally 50 feet minimum. However, there may be some instances when more than 50 feet of taper may
be required.The requirement for a longer taper will be determined on a case -by -case basis by the city
engineer.
(6)The city engineer shall investigate the existing conditions and if determined to be
substandard, the project shall sawcut and remove any existing pavement tapers when extending or installing
new pavement improvements.
§ 10-3-5 STREET STRUCTURAL SECTION (AGGREGATE BASE, ASPHALT BASE COURSE
AND ASPHALT SURFACE COURSE).
(A)Flexible pavement.The flexible pavement street structural section for public streets shall be the
minimum depths shown below.

§ 10-4-1 INTRODUCTION.
This article has been prepared as a guide for preparation of plans for stormwater drainage systems to
be installed within the City of Apache Junction.This Article along with the city's Standard Details,the
Maricopa Association of Governments ("MAG")Standard Specifications and Details,and the publications
Drainage Design Manual for Maricopa County, Arizona,Volume I,Hydrology and Volume II,Hydraulics
by the Flood Control District of Maricopa County ("FCDMC") should provide all of the information needed
for plan preparation.The Drainage Design Manual for Maricopa County, Arizona,Volume I,Hydrology
and Volume II,Hydraulics have been adopted by the city as a basis for design guidance and criteria, except
as amended herein.
§ 10-4-2 STORMWATER STANDARDS.
The city requires that stormwater runoff for new commercial, industrial, multi -family and residential
developments be managed as follows:
(A)Retention.The required retention to be contained is the stormwater runoff per divisions (A)(1)
and (2) below.Half pavements of the adjoining streets may be considered part of the development.
(1)For the areas north of Baseline Avenue, the following retention requirement shall apply:
One hundred ten percent of the stormwater which falls within the development from a 10 -year storm
of 24 -hour duration (approximately 2.4 inches) 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) (see A.J.C.C., Vol. II, § 10-4-10(B)(1) and (2)).
(2)For the areas south of Baseline Avenue, the following retention requirement shall apply:
Stormwater which falls within the development from a 100 -year storm of 2 -hour duration
(approximately 3.0 inches) must be retained within the boundaries of that development (including
street areas if within a subdivision) (see A.J.C.C., Vol. II, § 10-4-10(B)(1) and (2)).
(3)Surface retention is allowed in all newly developed areas.
(4)Underground retention is only allowed in commercial and industrial areas.
(B)Streets.
(1)Ten-year stormwater runoff Streets must be constructed to carry the stormwater runoff from
a 10 -year storm event as follows:
(a)For local streets, there shall be no curb overtopping with no requirements for dry lane
conditions.
(b)For collector, arterial and parkway streets, there shall be at least one dry 12 -foot driving
lane in each direction.
(2)One hundred -year stormwater runoff
58
(a)Calculated peak flow shall be considered to be contained within the right-of-way with:
1.Six-inch maximum depth over the curb;
2.One hundred cfs maximum flow; and
3.Ten fps maximum velocity.
(b)See A.J.C.C., Vol. II, § 10-4-6 for the street drainage design guide.
(3)Runoff in excess of street capacity.When the stormwater runoff in the streets exceeds the
10 -year or 100 -year conditions stated in divisions (B)(1) and (2) above, the excess flows shall be contained
in an approved storm drain and/or channel system.No open channels are allowed in the city's right-of-
way.
(4)Inverted crown streets.No new inverted crown streets are allowed within the city limits.
(5)Street cross drainage.Cross drainage shall be underground with culverts and bridges.Low
water crossings shall not be used without the city engineer's approval.
(C)Off -site flows.
(1)Off -site flows are flows that originate upstream of the proposed land development site and
have historically traversed either through the site or have been channelized in some form adjacent to the
project.
(a)Land development projects are required to convey the 100 -year, time of concentration
(Tc) peak flows around or through the project site. These off -site flows shall be interpolated from Apache
Junction's Stormwater Master Plan report.
(b)Off -site flows shall not be mixed with any stormwater flows originating from within
the project's contributing drainage area unless specifically approved by the city engineer.
(c)Off -site flows shall be carried through the development and discharged at a location
and in a manner consistent with historical flow patterns without adverse impact to adjacent, upstream or
downstream properties.
(d)Storm drains or box culverts shall be required when off -site flows are discharged from
a development site into public right-of-way.See A.J.C.C., Vol. II, § 10-4-7 for additional information.
(2)Note that "off -site flows" does not include the stormwater runoff from adjacent public right-
of-way that the project must retain in accordance with division (A) above.
(D)Special Flood Hazard Area (FEMA designated area).Any development or construction within
a special flood ha72rd area shall conform to FEMA flood plain development requirements and to the
requirements of the latest city floodplain management ordinance.See A.J.C.C., Vol. II, § 10-4-13 and
A.J.C.C., Vol. II, Chapter 5.

study.Existing washes can be relocated on -site based on a city -approved engineering study showing
adequate capacity and slope for the relocated washes. The washes must enter and leave the subject property
in the historic locations.This shall apply to the following lands within the corporate limits of the City of
Apache Junction, including but not limited to:
1.All special flood hazard areas as defined by FEMA;
2.FEMA zone X-500, also known as Shaded Zone X, as it pertains to alluvial fan or
sheet flooding;

previously and subsequently drainage studies commissioned by the city engineer.
7.Any ephemeral natural watercourses that convey runoff during rain events.
(b)For the purpose of this section, the following definition shall apply unless the context
clearly indicates or requires a different meaning.
FLOODPLAIN or FLOOD- PRONE AREA.Any land area susceptible to being
inundated by water from any source.For regulatory purposes this involves either a FEMA Special Flood
Hazard Area, areas platted on accepted city plans as being flood -prone or areas near washes which in the
opinion of the Floodplain Administrator may be impacted by water during a base flood.
(2)It is unlawful to divert, obstruct or retard a watercourse.Affected agencies or persons may
seek legal action.
(3)Construction in designated flood zones.
(a)Construction in an AH designated flood zone, as shown on the FIRM, requires an
existing site topography be prepared by a State of Arizona registered land surveyor and a city -approved
engineered grading plan.The lowest floor, garage and equipment is to be designed to be at least one foot
(State of Arizona regulatory flood elevation ("RFE") above the base flood elevation ("BFE")). Certification
by a State of Arizona registered civil engineer stating that the development will not raise the base flood
elevation more than one foot is required.
(b)A subdivision of five or more acres or 50 or more lots located all or partially in an A
designated flood zone shall have the base flood elevations determined for the A Zone.The base flood
elevations may extend outside the A Zone and the limits of the base flood elevations shall be shown on the
grading and drainage plan of the subdivision.The lowest floor, garage and equipment is to be designed to
the RFE.
60
(c)When constructing in an A designated flood zone, without designated floodway and
base flood elevations determined, the lowest floor of a structure shall be a minimum of two feet above the
highest adjacent grade ("HAG") at the pad location of the structure.
(d)Construction in an AE designated flood zone where the floodway and base flood
elevation is determined, the lowest floor of a structure to be constructed outside the floodway shall be a
minimum of 1 foot RFE above the base flood elevation shown on the FIRM.
(e)Construction in Flood Zones A and AE will allow fill dirt to be imported to the site with
a city -approved engineered grading plan. A city excavation and grading permit shall be required.
(f)After construction of the building and after all machinery and/or equipment such as
water heaters, air conditioners and other associated equipment have been installed and the grading around
the building is completed, a State of Arizona registered land surveyor or a registered engineer shall file a
finished construction FEMA elevation certificate for city files.
(4)Any grading resulting in alteration of floodwater capacity or re -alignment of a flood area in
an A Zone area may require an Army Corps of Engineer's 404 Permit and/or FEMA approval.
(5)Manufactured homes shall be elevated so that the bottom of the structural frame or the lowest
point of any attached appliances (e.g., ground -mounted AC unit), whichever is lower, is at or above the
regulatory flood elevation and be securely anchored to an adequately anchored foundation system to resist
flotation, collapse or lateral movement.
(6)Nonresidential buildings constructed in any A Flood Zone are to be elevated or floodproofed
to one foot above the base flood elevation or higher.A certification by a State of Arizona registered civil
engineer is required stating that the development grading and building will not raise the base flood elevation
more than one foot. An as -built FEMA elevation certificate prepared by a State of Arizona registered land
surveyor or registered engineer is also required.
(7)Constructing buildings on posts or pilings does not remove the building from the Special
Flood Hazard Area for flood insurance purposes.The posts or pilings are to be designed to resist lateral
movement due to forces of the floodwaters.
(8)Construction is prohibited in floodways unless it has been determined by a State of Arizona
registered civil engineer that construction will not increase flood levels during the occurrence of the base
flood discharge by any amount.Construction in the FEMA floodways as indicated on the area FIRM map
requires that there be no rise in the 100 -year flood elevation and certification letter by a State of Arizona
registered civil engineer to this.The work may require an Army Corps of Engineers 404 Permit and/or
approval of FEMA.
(9)Waste disposal systems cannot be installed wholly or partially in a floodway.
(10)Removing a property from a FEMA flood zone requires a State of Arizona registered civil
engineer to process a request in accordance with FEMA procedures.

engineer and in the specially designated Rural Area (see A.J.C.C., Vol. II, Appendix 10-B).
(b)Existing dip sections on public streets that are subject to widening requirements
associated with the development of adjacent properties are to be removed or modified.
1.Where the contributing stormwater flows to the existing dip section have been
eliminated or reduced to discharges associated with Apache Junction's design storms and topography
permits, the dip section shall be completely removed and the public street reconstructed.
2.Where topography or existing conditions do not permit the removal, the dip section
shall be modified so that flows associated with Apache Junction's design storms and lesser events are
conveyed via storm drain facilities and discharges associated with larger storm events would be allowed to
flow across the modified dip section in the historic fashion.
(4)Valley gutters.
(a)Valley gutters shall be used to transport runoff across local streets when a storm drain
system is not required.However, valley gutters are generally not acceptable for collector or arterial streets
and may do so only with the approval of the city engineer.
(b)In unusual cases, valley gutters may be required to cross collector streets in which case
a wider eight -foot design width shall be used and must be approved by the city engineer. Mid -block valley
gutters should be avoided.
73
(5)Maintenance.
(a)Access.Open channels to be properly maintained should provide reasonable access for
maintenance.Minimum width of access should be eight feet.Spacing between vehicular access points
should be a maximum of 1/2 mile.A minimum of one access point per subdivision is required.Non-
vehicular access points shall be provided every 660 feet maximum.If the facility is to be city -maintained,
the above minimum requirements are mandatory.
(b)Responsible party.Maintenance of drainage facilities within the city is usually the
responsibility of the property owner or the subdivision's homeowners' association.Specific maintenance
responsibilities should be called out on the recorded plat and the grading and drainage plan.

§ 10-4-10 DETENTION OR RETENTION FACILITIES.
(A)Retention methods.Allowable methods of providing stormwater retention are:
(1)Surface storage.Where surface storage (i.e., the traditional retention basin) of the required
retention is planned or provided, the basin(s) shall comply with the following:
74
(a)Irregular areas.Retention is to be accommodated within a limited number of well-
defined irregular shaped areas. Pursuant to the Apache Junction City Code, Vol. I, multiple small retention
basins are not acceptable for either public or private developments unless approved by the city engineer for
public developments and by the development services project engineer for private developments and are in
conformance with city standards.
1.To count separate retention areas as one, they must have the same high water
elevation and be connected by equalizer pipes.
2.On -lot retention is prohibited in all residential subdivisions.
3.Maximum depth of the required retention that shall be retained within a surface
retention basin is three feet (see division (D)(1) below).
4.The high water elevation shall be lower than the adjacent grades of adjoining
property unless an engineered berm is approved by the city.
(b)Within city right-of-way or PUE.
1.Retention facilities (surface basins, underground pipes, tanks and the like) are to
be located within the private property or "on -lot" of the proposed land development.Right-of-way areas
shall not be excavated, depressed or encroached upon without prior approval of the City of Engineer. When
allowed, the retention facility shall conform to division (D)(1).
2.Retention area(s) including the high water elevation limits for the design storm can
encroach into public utility easements ("PUE") subject to:
a.Adequate protection and cover is maintained for any existing public utilities.
b.Buoyancy calculations for the public utilities, whether existing or proposed,
are required when the pipe diameter is larger than 16 inches.
c.Where wastewater manholes exist or are planned within the high water limits,
the manholes shall have a watertight frame and cover per MAG Standard Detail 423, and the rim shall be
higher than the high water elevation of the design storm.
(2)Paved surface storage.In commercial and industrial areas retention may be accomplished
upon paved areas (e.g., impervious surfaces such as asphalt, concrete and the like).See division (E) of this
section.
(3)Underground storage.Underground storage utilizes storage tanks, vaults, pipes and the like
to place the required stormwater retention volume underground on the development site.Underground
storage is allowed for commercial retail and industrial type projects only.
(a)The design engineer shall consider the following during the design process for any
project involving underground storage:
1.Venting of the structure;
2.Access to the underground structure for routine maintenance;
75
3.Structural loads including any surface loads;
4.Buoyancy of the structure; and
5.Drainage of the structure within the required 36 hours.
(b)The engineer shall include in the drainage report for the project the justifications, design
criteria,operational and maintenance information for the underground structure and any associated
equipment such as pumps.
(c)See division (L) below for underground storage guidelines.
(B)Sizing.
(1)Basis of design.
(a)All retention/detention facilities shall be sized to retain the storm event falling over the
entire project (gross area including streets) (see division (B)(2)(a) and (b) below).For the purpose of
determining the volume required, the project shall be considered to extend to the centerline of all existing
and/or future streets on the exterior boundaries and to include all interior streets and other rights -of -way
within the project.
(b)There shall be a minimum of one foot freeboard from the water surface elevation to the
lowest building elevation and/or the gutter of the upstream streets.
(2)Volume required.The volume required for each retention/detention basin shall be calculated
as follows:
(a)North of Baseline Avenue:
VR =1.1 x 0.2 (Cpost - Cpre) x A
where:
VR =Retention volume required (cubic feet)
1.1 =An additional 10% of retained volume to account for losses due to sedimentation, weed
growth and the like
0.2 =10 -year, 24 -hour depth of rainfall (2.4 inches/12)
Cpost =a coefficient relating the runoff to rainfall for the proposed construction (per FCDMC
Drainage Design Manual,Volume 1, Table 3.2).
Cpre =a coefficient relating the runoff to rainfall for the existing condition (per FCDMC Drainage
Design Manual,Volume 1, Table 3.2).
A = drainage area, including 1/2 of all abutting streets (square feet)
76
(b)South of Baseline Avenue:
V R=0.25C x A
where:
VR =Retention volume required (cubic feet)
0.25 =100 -year, 2 -hour depth of rainfall (3.0 inches/12)
C = a coefficient relating the runoff to rainfall (per FCDMC Drainage Design Manual,Volume 1,
Table 3.2).
A = drainage area, including 1/2 of all abutting streets (square feet)
Drywell volumes shall not be included in the proposed storage capacities.
(3)Location.
(a)Retention/detention basins shall be located such that they can intercept the flows from
the entire site.
(b)If the basin is located other than at the lowest point of the project, the developer's
engineer shall denote on the master drainage map the actual or effective drainage area.If portions of the
project camiot drain to the primary basin, additional basins shall be added to retain runoff from these areas.
Credit will not be given for providing volume in excess of that needed to retain the required storm event
from a basin's effective drainage area.
(C)Volume certification.The developer will provide the city with certified as -built dimensions of
the basins and the actual volume of storage provided.This must be based on as -built topographic surveys
made by either a civil engineer or land surveyor who is registered to practice in the State of Arizona. These
as -built volumes must reflect permanent finished landscaping in place.The volumes shall be certified by
the design engineer that the volumes provided meet or exceed the required design volumes per city
ordinance and the approved drainage plan.The volume of storage provided must equal or exceed the
approved design volumes before the city engineer will issue letters of acceptance for maintenance of any
public facilities.
(D)Grading.
(1)Depths.
(a)Retention basins are not permitted within the city ROW. Where unusual circumstances
are encountered, retention basins may encroach in city ROW with prior written approval from the city
engineer. When retention basins are allowed to encroach, the basins shall not extend more than 10 feet into
the city ROW and shall not exceed 1.5 feet of water depth within the city ROW unless there is a fence or
other similar protection to restrict access to the area.
(b)The overall average depth shall not exceed three feet without authorization of the city
engineer.If granted, the basin must be fenced to prohibit access or a side slope of 8:1 shall be provided for
a minimum distance of 25 feet measured from the 100 -year high water level.
77
(c)While it is the city's intent that the "average" depth not exceed three feet, it is also the
city's intent that the basins be contoured to present an aesthetically pleasing appearance as determined by
the city engineer. Therefore, up to 25% of the bottom area may be up to four feet deep.
(d)In no case shall the depth exceed one foot without a positive means of disposing of
accumulated runoff.
(2)Slopes, side and bottom.
(a)Bottom.The bottom of all basins shall be sloped towards the discharge points.The
minimum bottom slope shall be 0.5%.
(b)Side slopes.
1.Side slopes adjacent to public rights -of -way, or when there is pedestrian type
access to that portion of the basin, shall have a side slope of 6:1 or flatter.
2.Side slopes adjacent to walls, fences, hedges and the like (e.g., no or limited
pedestrian type access in that area) may have side slopes up to 4:1.
3.Retaining walls (e.g., vertical slopes) may be used in areas adjacent to permanent
walls, fences and the like.
(3)Grading/landscaping/joint use as parks.
(a)1.It is the intent of the city that retention/detention basins present an aesthetically
pleasing appearance. The developer's engineer shall contour the sides and bottoms of the basins to enhance
appearance through varied slopes.
2.The developer and designer shall work with representatives of the city's
development services department and parks and recreation department to determine the need/desirability
and feasibility of joint usage of the basin as a park site.If appropriate, the design shall provide for
appropriate open areas for the recreational facilities.All design shall be approved by the city parks and
recreation department.
(b)It is not the intent of these standards to dictate the specific details of the configuration
to the designers; however, the following concepts will be used as the basis of reviewing the plans:
1.curvilinear sides should be used in lieu of long stretches of straight lines.
2.side slopes should be varied (e.g., start with 6:1 then change to 7-8:1 or more. With
appropriate use of landscaping, side slopes can even be reduced to 4:1.
3.bottom areas should contour to varying depths in lieu of uniform depth/slope.
(c)The tops and bottoms of side slopes shall be rounded off, generally over a distance of
five feet each way of the curve point of intersection ("PI").
(d)All landscaping within city ROW, easements or dedicated tracts shall be approved by
the city parks and recreation department.
78

on the master drainage map.
(b)No more than 50% of the required parking spaces shall be covered by stormwater
retention/detention.
(c)Storage system shall be designed to store the first 30% of the required runoff volume
off paved areas (to avoid nuisance water constantly ponding on the pavement).
(d)Depth of water shall not exceed six inches within the parking area, nor shall it exceed
0.15 feet at the midpoint of any parking space.
(e)Interference with pedestrian traffic will be minimized in the design of the storage
facility.
(f)A continuous fire access lane shall be provided throughout the development, and it shall
be free of ponded water from the retention areas.
(g)All parking spaces shall be accessible during periods when the basins are filled to
capacity, without pedestrians having to cross ponded water deeper than 0.15 feet.
(3)Before final plan approval, an approved drainage report must show the calculated stormwater
storage volume based on runoff from the 100 -year, 2 -hour storm, or the pre -approved 10 -year, 24 -hour
storm for the Downtown Area and in -fill projects north of Baseline Avenue.
(F)Overflow/outfall.
(1)Each project shall be designed such that the "ultimate" outfall for all drainage in excess of
the 100 -year, 2 -hour storm is routed to a public street, storm drain, drainage channel or natural watercourse.
The outfall shall be accessible without draining over private property.
(2)If such an outfall does not exist, the project must provide an outfall.
(G)Overflow/conveyance.

project.Off -site runoff volumes shall not be allowed across private lots, streets or public/private access
ways.
79
(2)Runoff volumes in excess of those required to be retained/detained may be routed directly
through the outfall, although they shall be routed via the retention/detention facilities.
(H)Location/conflicts with existing utilities.
(1)Retention/detention facilities shall not encroach into existing easements for private utilities
without written approval of the encroachment from all utilities using the easement.
(2)Retention/detention facilities shall not encroach into public ROW nor into public easements.

existing and planned future power facilities in their review.SRP approval letter shall be forwarded to the
city engineer before final city approvals.
§ 10-4-11 DRAINAGE EASEMENTS AND COVENANTS.
For a drainage easement, the following apply:
(A)A drainage easement is an area designed and used for conveyance and/or retention of stormwater
runoff in which nothing can be placed which will impede, divert or cause the runoff to have an adverse
affect on adjoining property.
(B)The city engineer requires that all drainage easements and covenants be recorded on a subdivision
plat or for those projects that do not require a land subdivision map or plat, the easements and covenants
will be recorded by a separate instrument or document.
(C)Public easements and covenants shall be prepared and recorded by the city engineer.Private
easements and covenants shall be prepared and recorded by the developer or representative after review
and approval of the associated documents.
84
(D)It is the developer's responsibility to execute or cause the execution of the legal documents. The
developer shall return the executed documents to the city engineer along with any recording fees as well as
provide recorded copies of all private easements in order to receive construction document approval and/or
permits.
(1)Public drainage easements.A public drainage easement is required if the stormwater
conveyance or storage occurs per the following:
(a)The conveyance is through city property.
(b)The storage is on city property.
(c)Where stormwater is conveyed from public right-of-way onto private property.
(d)Public easements can only be extinguished through city council action.
(e)The developer's engineer shall provide the following documents with the construction
documents for the preparation of a public drainage easement:
1.A sealed legal description of the easement area (Exhibit "A") (see Figure 10-7.1
in Article 10-7); and
2.A graphic exhibit of the easement area (Exhibit "B")(see Figure 10-7.2 in Article
10-7).
(2)Private drainage easements.Where the stormwater runoff will be retained on private
property in which any of the following is true, a private drainage easement is required.
(a)Where the stormwater is conveyed across property lines; or
(b)Where stormwater is stored in a common retention area.
(3)Temporary drainage easements.Where the stormwater is retained in an area subject to
future development, the easement can be described as a "temporary drainage easement." These easements
are treated the same, as regular drainage easements in that they are required to be recorded and can only be
extinguished through the submittal of revised easement documents for city review and approval and the
subsequent recording.
(4)Drainage covenants.A drainage covenant is a restrictive promise specifying the use of the
property relating to storm runoff, drainage and retention. A drainage covenant shall be recorded for private
property when it conveys or retains stormwater runoff from public streets or property.
§ 10-4-12 CONSTRUCTION AND INSPECTION.
(A)A responsible professional (e.g., civil engineer of record, land surveyor and the like) must certify
that the drainage and retention facilities were constructed in accordance with the approved plans or as noted
on provided as -built plans and that the facilities conform to city standards.
85
(B)The responsible professional shall utilize the drainage and retention certification letter, Exhibit
10-4.2 following the text of this Article to certify the stormwater management facilities.

(b)Variances shall not be issued within a designated floodway if any 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 and expense, nuisances or conflicts.
(d)Variances will result in increased premium rates for flood insurance.
(13)Failure to adopt or enforce floodplain management regulations will result in suspension of
the community flood insurance program; and
(14)FEMA elevation certificate prepared by a State of Arizona registered civil engineer or land
surveyor is required.
(C)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 or determine the base flood (Q100) elevation.

§ 10-A-1 GENERAL COMMENTS.
This Appendix 10-A describes the engineering design guidelines for the special designated area
known as the "Downtown Core Area" and the 8-3 zoning classification.
§ 10-A-2 INTENT.
The Downtown Core Area will be a mixed -use area that will include commercial and residential in a
walking environment.
125
§ 10-A-3 LOCATION.
The Downtown Core Area is shown on Apache Junction Standard Detail AJ-12.1.
§ 10-A-4 DESIGN GUIDELINES.
The design guidelines are detailed in the City of Apache Junction's Commercial Design Guidelines
and the Apache Junction Main Street Design Dictionary.
APPENDIX 10-B:RURAL AREA
Section

10-B-3 Design guidelines
§ 10-B-1 GENERAL COMMENTS.
This section describes the Engineering Design Guidelines for the special designated area known as
the "Rural Area."
§ 10-B-2 INTENT.
The Rural Area is intended to have a rural character to it with no curb, gutter, sidewalk or street
lights. The terrain and vegetation shall be minimally disturbed.
§ 10-B-3 DESIGN GUIDELINES.
(A)Street section and right-of-way requirements.See Apache Junction Standard Details AJ-20.6
through AJ-20.8 for the street section and ROW requirements for the Rural Area.
(B)Curb and gutter.No curb and gutter shall be constructed normally, but special circumstances
may require some.The city engineer will decide when curb and gutter and the type shall be required.
(C)Sidewalk.No sidewalk shall be constructed in the Rural Area.
(D)Street lights.No street lights shall be constructed in the Rural Area.
(E)Vertical profile of street.The vertical profile of a street in the Rural Area should have the
proposed edges of pavement near the existing ground to reduce the need for constructed slopes and to
facilitate overland drainage and/or existing wash crossings in dip -sections.
126
(F)Stormwater drainage.The stormwater drainage shall normally be conveyed across the Rural
Area streets in a dip -section per MAG Standard Detail 552.The dip -section shall only be used where:
(1)The calculated Q100 drainage flow will be less than 12 inches maximum depth at the dip-
section.
(2)The calculated Q100 drainage flow velocity at the dip -section shall not be detrimental to a
vehicle crossing the dip -section.
(3)A dip -section needs to act as a spillway area for a larger drainage flow that will not be able
to be conveyed totally under the street section (e.g., FEMA designated areas) when the depth or velocity
is too great for a normal dip -section.
(G) The city engineer shall reserve the right to require modifications to the above standards along
major arterial streets within the Rural Area.

10-C-4 Design guidelines
§ 10-C-1 GENERAL COMMENTS.
This section describes the Engineering Standards for the special designated area known as "Lost
Dutchman Heights."
§ 10-C-2 INTENT.
Lost Dutchman Heights is the area south of Baseline Avenue.This area will become the southern
portion of Apache Junction and has great potential for large parks, waterways, trail systems, residential,
commercial, light industrial and business park users, and a good lifestyle.
§ 10-C-3 LOCATION.
Lost Dutchman Heights is shown on Apache Junction Standard Detail AJ-12.1.
§ 10-C-4 DESIGN GUIDELINES.
(A)Street section and right-of-way requirements.
127
(1)The principal arterial and parkway roadways are shown in the Lost Dutchman Heights
Concept Plan prepared for Arizona State Land Department, a copy of which is on file in
the development services department.The streets are detailed in Apache Junction Standard
Details AJ-20.4 and AJ-20.5 and include 10 -foot meandering sidewalks and raised
landscaped medians.
(2)The remaining street sections are detailed in Apache Junction Standard Details AJ-20.1
through AJ-20.4.
(B)Utility locations.
(1)No utilities shall be constructed under the pavement areas in the principal and parkway
section streets except to cross intersections.
(2)The utility locations shall be:
(a)The sewer and water locations shall be on opposite sides of the roadway between the
back of curb and sidewalk (see Standard Details AJ-20.9 and AJ-20.10).
(b)The other utilities (gas, telephone, cable TV and the like) shall be located between the
sidewalk and right-of-way line (see Standard Details AJ-20.9 and AJ-20.10).
(C)Street lights.The street lights for the principal arterial and parkway street sections shall be
double -masted and mounted in the median.
(D)Stormwater management.
(1)There are a number of large washes that traverse the Lost Dutchman Heights area including
two FEMA "floodplain" designated washes (Weekes Wash and Siphon Draw).All streets crossing these
washes will need to have a method of conveying the 100 -year storm runoff under the streets, and provide
for overtopping of larger storm events to be contained within the crossing.
(2)On -site area stormwater management will need to meet the requirements of A.J.C.C., Vol.
II,Engineering Standards, Article 10-4 of this Chapter.
(3)A number of washes in the Lost Dutchman Heights area have been designated "Waters of
the U.S." and may require an Army Corps of Engineers "404 Permit" to develop within or adjacent to
these designated washes.
