GENERAL INFORMATION AND DEFINITIONS
A. Subdivision Approval Process
The process that the City of El Mirage uses to approve a subdivision is as follows:
1. Pre-application Conference. Prior to the submission of a preliminary plat, the subdivider
shall contact the Planning DirectorDevelopment Services Department and any other
administrative personnel or private agencies to determine procedures and requirements
for filing the sketch plat and preliminary and final plats. Availability of public water and
sewer or requirements when public systems are not readily available. Zoning
requirements on the property. Requirements of the duly adopted General Plan for major
and minor streets, land use, drainage, schools, parks, and other public open space. The
location and extent of any floodplains.
As a part of this contact, the subdivider may discuss with the Development Services
Department Planning Director, his or her tentative proposals for the development of the
property. The subdivider shall submit, and the Development Services Department
Planning Director shall review and comment on, a sketch plat prior to the preparation of
a preliminary plat. The Development Services Department Planning Director shall make
the review and make its comments known to the subdivider within five days from the
date of the review. The sketch plat shall contain or show two-foot contours and shall
address the requirements of division.
The purpose of this pre-application procedure is to determine any problems with the
proposed development before expenses are incurred in the preparation of a preliminary
plat. No official action is required other than to offer appropriate comments on the
proposal and indicating suitability for proceeding through the platting process.
2. Preliminary Plat Application. A Preliminary Plat Application shall be submitted to the
Development Services Department Planning Director or designee. The preliminary plat
shall consist of a drawing or drawings and supporting material and information a
prescribed by these regulations. The preliminary plat drawing shall be prepared at a
scale of one-inch equals 100 feet or larger for subdivisions where the majority of the lots
are less than five acres in size. The scale may be reduced to one-inch equals 200 feet for
subdivisions in which the minimum lot size is five acres or more. The face of the
drawing shall contain information as stated in Zoning Code §155.031 (A). The
preliminary plat shall include all information as requested in Chapter 1, Section B-1 of
this Manual.
3. Preliminary Plat Approval. The preliminary plat shall be approved by the Development
Services Department El Mirage Planning Commission once the El Mirage Technical
Advisory Committee (TAC) comments and redlines have been satisfied. The preliminary
plat shall be effective for one year from the date of approval. The subdivider may apply
in writing for, and the Development Services Department Planning and Zoning
Commission may allow for, up to a six-month extension.
4. Final Plat Application. The applicant/subdivider shall submit a Final Plat Application
together with the requirements in §155.032Chapter 1, Section B-2 of this Manual. Upon
submittal of all required supporting materials, the Development Services Department
Planning Director shall review them for completeness to determine whether a complete
final plat submittal has been made and shall refer the material to appropriate agencies for
review and comment. Upon being notified of the comments and any necessary approvals
of reviewing agencies, the Development Services Department Planning Director shall
forward the final plat, comments and approvals of reviewing agencies and pertinent
supporting materials to the Council. Incomplete final plats, or final plats for which
necessary approvals have not been secured, shall not be forwarded to Council for action.
5. Final Plat Approval. Following receipt of the final plat, the recommendation from the
Development Services Department Planning Director and Chairperson of the Planning
and Zoning Commission that the final plat complies with the preliminary plat, and
required supporting materials, the Development Services DepartmentCity Council shall
either approve the final plat or disapprove the final plat and notify the subdivider of the
conditions to be met to gain approval. If disapproved final plat is modified and
resubmitted to the Development Services Department City Council at a later date for
their consideration, the Development Services Department Council may require the
concurrent submittal of an updated ownership and encumbrance report or title opinion.
6. Plat Recording. The City Clerk shall record the Final Plat after Development Services
Department City Council approval and gathering of signatures. Preliminary Plats and
phasing plans are reviewed by the TAC Committee and approved by the Development
Services Department Planning Commission for the City. Final Plats are approved by the
Development Services Department City Council as a consent item on the Council
Agenda. The Engineering Division approves all street designs and engineering drawings
associated with right-of-way and drainage improvements proposed for construction in
the development. The Zoning Administrator reviews, approves and inspects the
landscaping in the City’s ROW and common shared areas.
B. Use of Professional Surveyors and Engineers
Drawings and maps required for the pre-application conference and Preliminary Plat
submittals need not be prepared by registered land surveyor or engineering professionals. A
licensed Land Surveyor registered in the State of Arizona shall prepare the Final Plat Map.
All other drawings, engineering drawings and final maps submitted for approval shall be
prepared by a licensed Professional Engineer registered in the State of Arizona.
C. Request for Design Exception
Technical provisions of this Design & Development Standards Manual may be waived or
modified through a Request for Design Exception. A copy of the request document, which
is located in the Appendix R of this Manual, shall be filled out and submitted to the
Engineering Division. There is no guarantee that the request will be approved.
D. Phasing Plans
Preparation of phasing plans shall be required when phasing of lot sales or public
improvements is proposed. The TAC Committee may approve preliminary and final phasing
plans. Phasing plans shall be considered when performance bonds or other final assurances
are accepted for proposed improvements.
E. Certificate of Correction or Change
Administrative changes to a plat may be approved through a Certificate of Correction or
Change. An application for a Certificate of Correction or Change may be considered and
approved by the City Engineer. Changes that can be approved administratively must be

Street Design for Developments Located Adjacent to Impediments
Where a development abuts or contains the right-of-way of a railroad, a limited access
highway, an irrigation canal or other physical impediment, or abuts a commercial or
industrial land use, the TAC Committee may recommend location of a street approximately
parallel to and on each side of such right-of-way at a distance suitable for appropriate use of
the intervening land. Such distance shall be determined with due regard for approach grades,
drainage, bridges, or future grade separations.
J. Street Design in Relation to Topography
Streets shall be so arranged in relation to existing topography as to produce desirable lots of
maximum utility, streets of reasonable gradient and facilitation of efficient drainage patterns.
K. Alleys
Alleys may be included but shall not be required in residential, commercial, or industrial
developments, except that alleys shall be required in all developments where:
1. The development abuts an existing, partially dedicated alley(s).

C-4
LOT PLANNING AND DESIGN
A. Lot and Block Arrangement and Dimensions
1. Lot width, depth, area, and building setbacks shall comply with the minimum
requirements of the El Mirage Zoning Ordinance and shall be appropriate for the location
and character of the proposed development, and for the type and extent of street and
utility improvements being installed.
2. Where lots are more than double the minimum required area for the zoning district, the
City may require that the lots be arranged so as to allow further subdivision and the
opening of future streets where they would be necessary to serve the potential lots, all in
compliance with the El Mirage Zoning Ordinance.
1.3. Dimensions of corner lots shall be large enough to allow for erection of buildings,
observing the minimum setbacks from both streets. Depth and width of properties
reserved or laid out for business, commercial, or industrial purposes shall be adequate to
provide for the off-street parking and loading facilities required for the type of use and
development contemplated, as established in the El Mirage Zoning Ordinance.
4. Maximum length of blocks, measured along the centerline of the street, and between
intersecting street centerlines shall be 1,000-feet or 15 times the minimum lot width
required in the Zoning District. Cul-de-sacs shall not exceed 600-feet in length.
2.5. The lot arrangement shall be such that there will be no foreseeable difficulties, for
reasons of topography or other conditions, in securing building permits to build on all lots
in compliance with the El Mirage Zoning Ordinance or in providing driveway access to
buildings on the lots from an approved street.
B. Relationship of Lots to Streets
1. Side lot lines shall be substantially at right angles or radial to street lines.
2. Every lot shall abut upon a public street or private street or access way designed and
appropriate for providing vehicular access.
3. Lot lines for private streets constructed to less than City street standards shall be extended
to the center of the street. Net lot area, for conformance with the minimum required lot
area for the zoning district, shall not include the street easement or tract area.
4. Double frontage and reversed frontage lots shall be avoided except where necessary to
provide separation of residential development from traffic arterials, to overcome specific
disadvantages of topography and orientation or Single-family residential lots extending
through the block and having frontage on two parallel streets shall not be permitted
except where the second street is designated as a collector or arterial street. The rear lot
line of through lots shall be buffered as determined by the Development Services
Department.
4.5. Lots shall not, in general, derive access exclusively from an arterial street. Where
driveway access from an arterial street may be necessary for several adjoining lots, the
City may require that the lots be served by a combined access drive in order to limit
possible traffic hazards on the street. Where possible, driveways should be designed and
arranged so as to avoid requiring vehicles to back into traffic on arterial streets.
C. Utility Easement Planning
1. Where alleys are provided, four-foot aerial overhead easements on each side of alley shall
be provided by dedication.
2. Guy and anchor easements shall be one-foot wide on each side of a lot line and
approximately 35-feet in length measured from the rear lot line.
SECTION G
ADMINISTRATIVE CHANGES TO A RECORDED PLAT
Minor changes may be accomplished without re-recording the plat through the Certificate of Correction
administrative process. Allowable changes under this process are engineering errors and name changes,
typographical errors, misspellings, etc. Administration changes to the recorded plat must be reviewed by
the Development Services DepartmentPlanning Director, prior to recording.

shall be made on the face of the plat listing all corrections made and the book and page
numbers where the original plat was recorded. The Development Services Department
director shall review the plat for corrections, secure the signatures of the proper public
officials on the corrected plat, and present approve the plat to the Development
Services Department City Council for the reaffirmation of their approval and submit
the plat to the County Clerk for recording. The recording of the corrected plat shall
void the incorrect original plat, and the County Clerk shall note “Void” across the face
of the incorrect plat.
B. Procedure
1. If, after the approval and recording of the final plat, a subdivider wishes to modify the
location of lot lines on part or all of the recorded plat, and if there is no change in the
location or size of dedicated streets or other dedicated public land, the subdivider shall
submit a new final plat drawing with the lotting arrangement revised. The
Development Services DepartmentPlanning Director shall determine which of the
required supporting materials shall be resubmitted with the revised final plat. The plat
shall be marked the “Resubdivision of ” under the name of the
development and shall be processed as a final plat.
2. If, after the approval and recording of a final plat, a subdivider wishes to change the
street or public land location, size, or arrangement of a part or all of the platted area,
the resulting subdivision shall be treated as a new submittal with both a preliminary
plat and a final plat required. The subdivision shall be identified as the “Resubdivision
of ”. Any action of the Development Services Department City
Council approving the resubdivision shall contain clear reference to the vacation of
public lands as appropriate.

poles.
2. Installation of new facilities or major enhancements to existing facilities shall be installed
underground unless it can be demonstrated that the public’s general health, safety and welfare
are affected by the underground installation. The fact that an underground installation is more
costly than an overhead installation shall not, in and of itself, constitute a health or safety
issue.
3. All above ground appurtenances that are required to provide services shall be designated and
installed with attention to minimizing the number of appurtenances, joint location,
combined use with existing boxes, and shared facilities where ever possible. All locations
will meet industry standards for sight distance locations, all industry safety requirements
and the aesthetic requirements of the City. A permit shall be issued for the installation or
conversion of any overhead to underground facilities. The issuance of a permit in violation
of any requirements will not void the permitee’s responsibility unless the standard
installation is clearly noticed and approved separately from normal permit requirements.

1. Traffic Signs and Pavement Markings – All new developments and roadway projects shall
provide the required traffic control signs, street name signs, sign posts and pavement
markings on all streets and intersections. The Developer is responsible to furnish and install
the signs, posts and markings. Final Certificate of Completion and Construction bonds
will not be released and streets will not be opened to the public until all signs and markings
have been installed.
2. Signing and Striping Plan – shall be submitted to the Engineering Division and
approved through the plan review process. All new and existing signs shall be shown on the
plans. It is the Design Engineers’ responsibility to design the Signing and Striping Plan to

2. Street Classification Map. Whenever the development embraces any part of a street
designed in the adopted Streets Classification Map, such street shall be platted in conformity
therewith.
3. Continuation. The arrangement of streets shall provide for the continuation of principal
streets between adjacent properties when the continuation is necessary for convenient
movement of traffic, effective fire protection, for efficient provision of utilities, and
where the condition is in accordance with the General Plan. If the adjacent property is
undeveloped and the street must be a dead-end street temporarily, the right-of-way shall
be extended to the property line and there shall be a notation on the subdivision plat that
land outside the normal street right-of-way shall revert to abuttors whenever the street is
continued. The city may limit the length of temporary dead-end streets in accordance
with the design standards of these regulations.Street layouts shall provide for the
continuation of existing collector streets in adjacent areas, and such other streets as the
City Engineer may designate.
3.4. Frontage on Improved Streets. No subdivision shall be approved unless the area to be
subdivided shall have frontage on, and access from, an existing street and unless the street is:
A street shown upon a plat approved by the City and recorded in the County Recorder’s
office. The street or highway must be suitably improved as required by Maricopa Association
on Governments (MAG) Specifications, or be secured by a performance bond required under
the City’s Subdivision Regulations, with the width and right-of-way required by these
regulations or the General Plan. Wherever the area to be subdivided is to utilize existing road
frontage, the road shall be suitably improved as required by these regulations and as outlined
in this manual.
4.5. Future Street Extensions. Proposed streets shall be extended to the boundary lines of the
tract to be subdivided, unless prevented by topography or other physical conditions, or
unless in the opinion of the City, the extension is not necessary or desirable for the
coordination of the layout of the subdivision with the existing layout or the most
advantageous future development of adjacent tracts.Certain proposed streets, as
designated by the City Engineer, shall be extended to the development boundary to
provide future connection with adjoining unplatted lands. In general, these extensions
should not be farther apart than the maximum permitted length of a block, as specified
herein.
5. Local Street Arrangement. Local streets shall be so arranged as to discourage their use by
traffic originating outside the immediate neighborhood. Local streets shall be discontinuous
and generally should be interrupted with jogs and offsets. Four-way intersections of local
streets should be avoided. Local roads shall be curved wherever possible to avoid
conformity of lot appearance.
6. Marginal Access and Reverse Frontage Streets. Lots intended for single-family residential
use shall not front or have access from arterial streets. When a proposed development
abuts or contains an existing or proposed arterial street, the arrangement of interior streets
and lots shall prohibit marginal access streets and minimize reverse frontage streets, and
shall provide non-access easements along the arterial street, or such other treatment as may
be justified for protection of properties from the nuisance and hazard of high volume
traffic and for preservation of the traffic function of the arterial street.
7. Access Provisions for Development Boundary Constraint. When a residential subdivision
abuts the right-of-way of a railroad or limited access highway or abuts a commercial or
industrial land use, the City Engineer may require location of a street approximately
parallel to such right-of-way or use at a distance suitable for appropriate use of intervening
land, such distance being determined with due regard for approach grades, drainage,
embankments, bridges, and future grade separations.
8. Dead End Streets. Dead End Streets shall be prohibited except in locations approved by the
City Engineer for future street connection to adjacent unplatted lands.
a.
Where a street does not extend to the boundary of a subdivision and its continuation
is not required by the city for access to adjoining property, its terminus shall normally not
be nearer to the boundary than 50 feet. However, the city may require the reservation of
an appropriate easement to accommodate drainage facilities, pedestrian traffic, or utilities.
A cul-de-sac shall be provided at the end of a permanent dead-end street in accordance
with city construction standards and specifications.
8.b. For greater convenience to traffic and more effective police and fire protection,
permanent dead-end streets shall, in general, be limited in length in accordance with the
design standards of these regulations.
9. Maximum Lengths for Blocks and Cul-de-sacs.
a. Maximum length of blocks in residential areas, measured along the centerline of the
street, and between intersecting street center lines, shall not exceed 1000-feet or 15
times the minimum lot width required in the zoning district. Blocks shall be as long
as reasonably possible under the circumstances within the above maximums in order
to achieve depth and possible street economy and to reduce the expense and safety
hazard arising from excessive street intersections.
b. The maximum length of cul-de-sac streets shall not exceed 600-feet, measured from the
intersection of right-of-way lines to the extreme depth of the turning circle along the
cul-de-sac street center line, unless specifically approved by the Engineering
Division. An exception may be made where topography constrains the number of
adjacent lots served and shall not be made merely because the tract has restrictive
boundary dimensions. In such cases, provision should be made for extension of the
street pattern to the adjoining unplatted parcel and a temporary turnaround installed,
or to alter the street pattern to eliminate the constraint. Cul-de-sac streets shall
terminate in a circular right-of-way 60-foot in radius with an improved unobstructed
traffic turning circle of at least 48 feet in radius. Refer to City Detail EM-114.
c. Blocks shall have sufficient width to provide for two tiers of lots or appropriate depths.
Exceptions to this prescribed block width shall be permitted in blocks adjacent to major
streets, railroads, waterways, or parks.
b.d. In long blocks the City Council may require the reservation of an easement through the
block to accommodate utilities, drainage facilities, emergency access, or pedestrian
traffic.
10. Railroads and limited access highways. Railroad rights-of-ways and limited access
highways where so located as to affect the subdivision of adjoining lands shall be treated
as follows:
a.
In residential districts a buffer strip at least 25 feet in depth in addition to
the normal depth of the lot required in the district shall be provided adjacent to the
railroad right-of-way or limited access highway. This strip shall be part of the platted
lots and shall be designated on the plat: “This strip is reserved for screening. The
placement of structures, except for street signs and lighting is prohibited.”
b. In districts zoned for business, commercial, or industrial uses, the nearest street
extending parallel or approximately parallel to the railroad shall, wherever
practicable, be at a sufficient distance therefrom to ensure suitable depth for
commercial or industrial sites.
c. Streets parallel to the railroad when intersecting a street which crosses the railroad at
grade shall, to the extent practicable, be a distance of at least 150 feet from the
railroad right-of-way. The distance shall be determined with due consideration of the
minimum distance required for future separation of grades by means of appropriate
approach gradients. This distance shall be reviewed as part of a Traffic Impact Study
and increased as necessary based on the volume, configuration, etc. as determined by
the Traffic Engineer.
11. Widening and realignment of existing streets. Where a subdivision borders an existing
narrow street or when the General Plan or Zoning Ordinance indicates plans for
realignment or widening of a street that would require the use of some of the land in the
subdivision, the applicant shall be required to improve and dedicate at his or her expense
the areas for widening or realignment of the streets. The streets shall be improved and
dedicated by the applicant at his or her own expense to the full width as required by these
subdivision regulations. Land reserved for any road purposes may be counted in satisfying
yard requirements of the Zoning Ordinance, whether the land is to be dedicated to the
municipality in fee simple or as an easement for future expansion or as a private street.
10.12.
Non-Vehicular Access. Access to the parkway, arterial and major collector streets
shall be restricted by use of a one-foot, Vehicular Non-Access Easement (VNAE) at
locations other than street intersections and legitimate driveways.
11.13.
Topography: Streets shall be arranged in relation to topography as to produce desirable
lots of maximum utility and streets of reasonable gradient, safe ingress-egress and to
facilitate adequate surface drainage.
C. Design Standards
material, such as Portland cement concrete, concrete pavers, or other materials approved
by the Engineering Division. The surface should be crowned and have the same cross-
slope as the street pavement.
c. Unpaved and Landscaped Medians. These medians are greater than five-feet in width
and are unpaved. Features present in the median, i.e., landscaping, or other types of median
features shall not restrict sight distances per the City Details EM-158 and EM-159.
Mature vegetation size and maintenance should be considered when designing
landscaping in median areas. At no time should landscaping impede on sight distance
triangles.
4. Curbs. All curbs except for mountable curbs shall conform to the appropriate MAG Standard
Detail and MAG Standard Specifications, except that concrete for curbs shall be Class
‘A’ concrete, per MAG Standard Specification 725. For mountable curbs refer to MAG
Standard Detail 220-2, Type E.
a. Vertical Curbs. Vertical curbs are required for all streets. Vertical curbs with gutter are
to be constructed in accordance with MAG Standard Detail 220-1, Type ‘A’. Vertical
curb and gutter shall match the adjacent pavement slope to the gutter cross section
direction. The curb height shown on the Standard Detail is six-inches, but where fire
lane or public maintenance vehicle access to abutting property must be provided, the
curb must be flush with the adjacent grade. must be provided over the curb, use
mountable curb, per MAG Standard Detail 220-2, Type E.
b. Roll Curb, Ribbon Curb, Maricopa Edge. Roll curb is not allowed along local residential
streets unless approved by the City Engineer. If allowed, roll curb shall be constructed
in accordance with MAG Standard Detail 220-1, Type ‘C’. Ribbon curb may be used
for rural local roads or low volume industrial roads when approved by the City
Engineer. If allowed, ribbon curb shall be constructed in accordance with MAG
Standard Detail 220-1, Type ‘B’. When ribbon curb is used, drainage runoff from the
road shall not drain with the road but shall be directed to roadside ditches. See Chapter 4
for additional details. For rural local roads, a Type ‘A’ Maricopa Edge per MAG
Standard Detail 201 may be used when approved by the City Engineer. When a
Maricopa edge is used, drainage runoff from the road shall not drain with the road but
shall be directed to roadside ditches.
c. Cut-Off Walls. In locations where dip sections are permitted to allow drainage flows to
cross roadways, cut-off walls conforming to MAG Standard Detail 552 shall be
installed. Cut-off walls shall be at least three-feet deep and have a top that is flush
with the pavement surface. The exposed portion of the cut-off wall shall have the
appearance of ribbon curb, with the same width as the street’s regular curb and gutter.
The cut-off walls shall extend across the flow path in the dip section to protect the
pavement structure during runoff flows from a 100-year storm event. Transitions will
be needed between the regular curbs and the cut-off walls at each end of the dip
section.
degrees with approval of the City Engineer) on parkways, expressways, arterial streets and
major collector streets; and by a maximum of 4 degrees (15 degrees with special approval of
the City Engineer) on minor and local collector streets and local streets. An oblique street
should be curved approaching an intersection and should be approximately at right angles
at least 100 feet therefrom. Not more than two streets shall intersect at any one point
unless specifically approved by the City Engineer.
2. 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
intersection is desirable as a safety measure.
3. Intersection Sight Distance. In order to provide the opportunity for vehicles at an
intersection to safely cross or make left or right turns onto a through street, adequate sight
distance must be provided. Sight lines are to be drawn on roadway and landscaping plans to
represent the areas that must be free of all objects and topography in excess of 30-inch above
the roadway surface. City Detail EM-158 depicts the technique used to determine driver’s
eye locations; a line is then drawn to connect these two points. Continuous unobstructed
line of sight must be provided along this line and throughout the approach to the intersection,
providing an unobstructed sight triangle to the side street driver. Vegetation placed within
the sight triangle shall be of a low variety that remains below 30-inch when mature. Trees
can be considered within the triangle as long as the canopy is above 7-feet and if it is a single
trunk variety.
a. Right Angle Intersection. If the street intersection legs meet at an angle of 88 to 90
degrees, the sight distances shown in City Detail EM-158 are to be used to calculate the
sight triangle. If high volumes of truck traffic are anticipated on other than local
Industrial Street, the procedures in the AASHTO publication, A Policy on Geometric
Design of Highway and Streets should be consulted to determine the necessary sight
distances.
b. Skewed Intersections. For skewed intersections where the intersection angles are less
than 88 degrees, sight distances must be calculated in accordance with the procedures
described in Chapter 9 of the AASHTO publication A Policy on Geometric Design of
Highways and Streets.
c. Intersections within or near a curve. Distances ‘A’ and ‘B’ shown in City Detail EM-158
shall follow the street alignment when the intersection is within or near a horizontal
curve.
d. Unobstructed View Easements. Unobstructed view easements should be used as a
means to limit the height of structures, vegetation, and other improvements on corner
properties immediately adjacent to intersections. Unobstructed view easements are not to
be used as a substitute for intersection sight distance. Unobstructed view easements
provide additional visibility around corners for all intersection approaches and should be
applied to the design of perimeter walls and landscape features. Items within the
unobstructed view easements shall be no higher than 30-inch measured from the roadway

STORM DRAINAGE FACILITIES - DESIGN AND CONSTRUCTION
4-1
GENERAL INFORMATION
A. Intent
The guidelines contained in this section are intended to expand upon and supplement
information contained in legally adopted Chapters of the El Mirage City Code. The City will
not recommend for approval any plat which does not make adequate provision for storm or
flood water run-off channels or basins.
B. Requirement for Storm Drainage
All developments within the City shall provide such storm drainage facilities as are necessary
to ensure that all improvements, structures and properties, both within the subject
development and those located upstream and downstream of the development, shall be
protected from the adverse impact of storm water due to the proposed development.
Owners, developers, engineers, and/or contractors are required to prepare a Storm Water
Pollution Prevention Plan (SWPPP) for developments within the City of El Mirage with a
disturbed area of one acre or greater, or are part of a common plan of development or sale
that will ultimately disturb one or more acres. The City website contains a SWPPP Guidance
Document to aid in the preparation of a SWPPP. Each development shall comply, as a
minimum, with NPDES notification to the EPA and implementation of SWPPP control
measures, as defined and required by the “Best Management Practices” of the Drainage
Design Manual for Maricopa County.
C. System Classification
1. The "Minor System" (10-year) shall consist of those collection and/or storm water storage
facilities necessary to collect, convey, retain and/or detain storm water runoff from the
more frequent rainfalls. The "Minor System" shall be designed to accommodate storms
up to and including a "10-year storm" and shall be used only when specifically approved
by the City Engineer.
2. The "Major System" (100-year storm of duration as defined by the Drainage Design
Manual for Maricopa County) shall consist of those facilities necessary to convey storm
water runoff from storms up to and including a "100-year storm." It consists primarily of
the planning and/or analysis of the overall drainage system to insure: that there is always
positive drainage from all areas, that the "100-year" flows can safely pass through the
project, and that all structures are above the 100-year water elevation in areas where
temporary and/or long duration ponding may occur as well as those areas lying within the
FEMA floodplain.
D. Drainage Facilities Components
1. Collection System. This portion of the system is intended to collect and convey runoff to
storm water storage, trunk line storm drain facilities and/or outfall into natural and man-
made drainage channel facilities. The storm water drainage system shall be separate and
independent of any sanitary sewer system.
2. Storm Water Storage Facilities. Storm water storage facilities are defined as any
apparatus, device, manmade construction or method for temporarily storing, suspending
storm water runoff and releases by means of basins, channels, swales, wetlands, ponds,
lakes, vaults, cisterns, or any other means approved by the City Engineer. This portion
of the system is intended to retain, detain, store or suspend sufficient volumes of runoff to
minimize the adverse impact of new developments upon downstream areas. All
developments must provide storm water storage facilities, which consist of one or both of
the following as provided below:
a. "On-Site" facilities, for private property to be maintained by the property owner or
owner’s association are required for any or all of the following types of
developments.
(1) Apartment complexes
(2) Town homes, Condos, Patio Homes and/or locations where a Homeowners
Association will maintain the common area and drainage facilities.
(3) Large lot Single Family parcels, where the lot is at least one-half acre or larger.
(Note: this is an option in lieu of "off-site or public facilities").
(4) Industrial Developments including Subdivisions (Note: this is an option in lieu of
"off-site or public facilities").
(5) Commercial Developments including Commercial Subdivisions.
(6) Any lot being developed, permanently or temporarily, for any purpose, including
materials or commodity storage, parking, open space, structures of any kind or
temporary use consistent with the Zoning Code.
b. "Off-Site" facilities, for projects in a separate tract dedicated, as “Public Drainage
Easements”, to the City and to be maintained by an association of owners, are
required of the following types of development:
(1) Single-Family lots (regardless of acreage) that are part of a subdivision.
(2) Planned Area Developments (PAD) or other large master planned developments.
c. Storm water storage facilities shall be protected from further development by a
recorded drainage easement and must be fully improved with landscaping, irrigation
systems, lighting and such other aesthetic improvements as may be required by the
City. Any basin, which is accepted by the City for maintenance, shall be deemed
public property and shall be dedicated to the City in fee simple title. If the City does
not accept a basin for maintenance, the developer shall be responsible for establishing
some satisfactory means to maintain the area.
3. Open Channels. Channels consist of facilities that collect, store, suspend, convey and
discharge accumulated runoff by means respectively described as follows:
a. Natural Channels: Are described as Rivers, washes, arroyos, lakes, wetlands, or other
“volume provided”.
b. All storm water storage facilities are required to provide sufficient volume to retain
100 percent of the 100 year, 1-hour storm (must use 2.4 inches) for the sub-basin that
it serves. The routing of storm drainage for the development shall be through the
storm water storage facilities.
Detention style storm water storage facilities shall be designed for the volumes and
discharge rates as defined by the Flood Control District of Maricopa County for
purposes other than a storm water storage retention function. Design of the facilities
shall meet the criteria of the appropriate recommended procedure level defined by the
ADWR “State Standard for Stormwater Detention/Retention”, SSA8-99 (or current
version).
c. A drainage easement shall be recorded over the tract or parcel containing each storm
water storage facility within the project for both "public" and "private" facilities. The
drainage easement shall include a 20-foot access easement from a paved surface. For
publicly maintained basins, channels and other drainage facilities, the 20-foot access
easement shall connect to a public street.
d. For the complete half right-of-way area of adjacent streets and parkways, a storm
water storage facility located outside of the right-of-way, is required to provide the
equivalent calculated volume required to retain one hundred percent of the 100-year,
1-hour storm (2.4 inches) for that area. The basin is not required to intercept that
right-of-way flow unless required by the City.
e. Storm Water Storage facilities shall not be located within public rights-of-way, water,
sewer or utility easements.
f.
Two or more developers may join together to provide a common retention facility. A
letter of agreement signed by all developers participating in the common retention
area must be presented to the City Engineer, and the recorded plat shall indicate that
the retention area is a joint facility. The joint retention area must meet all criteria as a
single area.
e.g. No 100-year flow line shall encroach upon the minimum building setback line.

Engineer may make exceptions on a case by case basis.
4. The sub-drainage areas for each basin shall be denoted on the plans and the calculations
for each sub-basin storm water storage required shall be provided. Overflow from any
sub-basin may be safely routed to another sub-basin, to ultimately be contained in the
compilation of storm water storage provided. The storm water storage provided shall
contain 100% of the 100-year, 1-hour storm event, as actually routed through the
development. Over sizing (having a capacity greater than the possible capture volume) of
intermediate basins will not be considered for the provision of storm water storage
required beyond the volume of the contributing area.
5. Underground or concealed storm water storage facilities may be considered on a case by
case basis. Installation of approved underground facilities shall conform to Section 4-
2.A.8 and City Detail EM-406.
6. The High Water Level (HWL) shall be denoted on the plans for each basin or ponding area.

3.4. The design engineer is responsible for evaluating site specific design conditions.
4.5. All other applicable City, State, County and Federal Codes and Guidelines.
B. Requirement to Connect
All developments, including single-family residences, are required to connect to the City’s
wastewater system. The connection to the City’s wastewater system and the extension of the
public sanitary sewer are required for all new construction or for modifications to existing
disposal systems.
Waivers to this requirement may be granted if the public sewer is determined to not be
available to the subject property. A public sanitary sewer can be considered “not available”
according to the following:
1. The extension of the sanitary sewer is greater than 1320-feet from the City wastewater
system for a multi-family, commercial or industrial site or within 300-feet and directly
adjacent to a single-family residential lot (see City Code Section 51.049).
2. The applicant demonstrates the inability to obtain necessary easements upon reasonable
pursuit.
3. There is not adequate capacity or depth in the existing public sanitary sewer.
C. Wastewater System Facilities
Water System Facilities include the: lift stations, force mains, chlorine flushers, odor control
sites, and all other appurtenances required for proper treatment, conveyance, and disposal of
wastewater within the system.
It is the responsibility of the design engineer to review the most current edition of the Water
and Wastewater Master Plan and determine what additional wastewater infrastructure is
necessary to serve the proposed development. The Public Works Department will utilize the
most current edition of the Water and Wastewater Master Plan and operational knowledge of
the system to determine which facilities or upgrades are the requirements of the new
development.
D. Exceptions to the Design Guidelines

6-2
DESIGN STANDARDS
A. General
1. Materials. Refer to City Detail EM-101-12 for allowable materials. The design engineer
must specify the exact pipe material in the construction drawings that are in accordance
with the City approved pipe materials. Modifications to the pipe material will require a
formal plan revision and must be approved by the design engineer and the City of El
Mirage.
2. Conveyance. Rights-of-way and easements shall be dedicated prior to any construction or
with the Final Plat of the development.
3. Pavement Replacement. Pavement replacement type and compaction type shall be
indicated per MAG Standard Details and Specifications on each sheet or as modified in
the City of El Mirage General Notes.
B. Classification of Sewer Lines
The City's sewer system includes four classifications of wastewater lines, which are
determined by use or location within the system, identified below: Wastewater lines shall be
sized to accommodate their ultimate service area. Larger mains may be required dependent
upon the maximum flows anticipated with full development of the ultimate service area, with
additional consideration given to land use. The minimum size line for any public main is 8-
inch diameter. Non standardNonstandard sizes will not be allowed unless approved by the
Public Works Department.
1. Service Line. The public sewer pipe that extends and connects the customer’s private
building sewer to the lateral sewer.
2. Lateral Sewer. A sewer pipe that collects flow from one or more services and discharges
to another lateral sewer or a trunk sewer.
3. Trunk Sewer. A sewer pipe that receives flow from lateral sewers and connects to an
interceptor sewer. Trunk sewers are generally 15” in diameter and larger. Trunk sewers
may have some limited connections to services.
4. Interceptor Sewer. A large sewer pipe that receives flows from a number of trunk sewers,
and lateral sewers, and conveys such wastewater to a point for treatment or disposal. No
service connections are allowed into interceptor sewers.
4.5. Cleanouts and lampholes will not be permitted.
C. Location of Sewer Lines
1. Limited Access Parkway - sewer main alignment shall be reviewed individually.
2. Arterial streets - sewer mains shall be offset from the street centerline 13-feet south or
west.
3. Collector streets - sewer mains shall be offset from the street centerline 6-feet south or
west.
4. Local streets - sewer mains shall be offset from the street centerline 6-feet. For
curvilinear streets the offset from the street centerline can range from 6 to 9-feet south or
west.
5. Generally, the intent is to avoid locating the manhole covers so that wheel line of normal
traffic does not track over the casting. The location for the covers and lids should not be
closer than 6-feet from the street drainage flow line or gutter line.
6. All sewers shall be parallel to the centerlines or as close to parallel as possible.
7. In cases where public sewers are authorized outside of public rights-of-way, all such
sewers shall be centered and parallel to the property lines or as close to parallel as
possible.
8. Vertical and horizontal separation from water lines shall be in accordance with MAG
Section 610.5, MAG Standard Detail 404-1 and City Detail EM-402.
9. No part of any manhole shall be located any closer horizontally than the depth of cover or
6-feet, whichever is greater, from any wall, fence or structure, etc.
10. Public sewer lines will not be permitted within the limits of retention/detention basins.
11. Sewer service lines shall not be located under driveways or under concrete aprons
adjacent to driveways.

2. Sewer lines shall be located within public rights-of-way or centered within a 20-foot wide
easement dedicated for sewer line, or within a 30-foot wide easement (minimum width)
dedicated for both water and sewer lines. Larger easement widths with a minimum clear
width equal to twice the depth of cover will be required for deeper installations as
determined by the Public Works Department or Engineering Division.
3. No other parallel utilities shall be located within the public water or sewer easement.
4. Underground retention and above ground retention basins are not permitted to cross or be
within designated public water or public sewer easements.
5. Trees and substantial plantings are not permitted within designated public water or public
sewer easements where the easement provides primary access to the utilities. Plantings
must typically be at least 5’ from the centerline of the pipeline.
E. Cover and Depth
1. Maximum depth for sewer lines and manholes shall be 12-feet unless detailed loading
calculations and materials selection is approved with the written request by the

The City of El Mirage requires all development that disturbs one acre or more to submit the
required Storm Water Pollution Prevention Plan (SWPPP), including the Notice of Intent (NOI).
The owner/developer is still required to submit all required documents to the Arizona
Department of Environmental Quality (ADEQ) as required by law. The site
https://azdeq.gov/node/1143 is designed to provide you with a quick and easy way to file a
Notice of Intent (NOI) online for permit coverage, apply for a waiver, or file a Notice of
Termination (NOT) to terminate coverage under the AZPDES Construction General Permit,
AZG2025-001 or call ADEQ at (844) 827-4768 for assistance.
In addition, the SWPPP shall include all requirements of Maricopa County Rule 310 and all
requirements of the El Mirage City Code as it pertains to storm water. Copies of all
requirements, forms and guidance are available in the latest version of the Drainage Design
Manual for Maricopa County Volume III Erosion Control available at the Flood Control District,
2801 West Durango, Phoenix, Arizona 85009, Phone No (602) 506-1501.
This checklist serves to minimize redline comments on the check prints and to maintain
consistency among plan reviewers on plans for Storm Water and Dust Control Management.
Plan approval, issuing permits, and certain grading clearances depend on compliance with the
comments made on the check prints and this checklist. The engineer of record shall satisfy
themselves of the completeness and accuracy of the design. This review shall serve as a courtesy
review only. The Owner is ultimately responsible to ensure that all of the requirements outlined
under AZPDES are followed.
Please upload this checklist and the check prints with your next submittal. Discussion of
redline comments on plans or this checklist should be directed to the City Plan Reviewer.

The following is a checklist of information that is to be included in the SWPPP. Additional
information regarding the data to be included in the SWPPP is provided in the Construction
General Permit issued by ADEQ. The Construction General Permit can be downloaded from:
https://static.azdeq.gov/permits/cgp/2025permit.pdf
Existing Conditions – show existing contours, floodplain limits and any stormwater
structures on or adjacent to the project site.
Construction Activity Description - the SWPPP must contain a description of the purpose
or goal(s) of the construction project (e.g., a single-family residential, commercial
development, etc.). Additionally, the SWPPP must list all soil-disturbing activities
necessary to complete the project (i.e., clearing, excavating, and stockpiling).
Final Slope Grades - Location and steepness of slopes after grading.
Final Drainage Patterns – Drainage patterns of the site after major grading activities and
the location of the points where storm water will discharge from the site.
Disturbed Areas - Location and areas of soil disturbing activities or the total area of the
site where soil will be disturbed. (This must be identified on the map and area called-out).
Undisturbed Areas – The SWPPP shall reflect all areas designated as being undisturbed.
This would include Natural open space, jurisdictional washes (Per section 404 of the
CWA), etc. All designated areas must be delineated/ and fenced-off in the field.
Offsite Flows – Show location of offsite flows including quantities. If offsite flows are
being rerouted through the site, a note should be added to reflect the no disturbance zone.
Erosion and Sediment Controls – The SWPPP must describe the erosion and sediment
4
controls to be used during construction. Such controls include stabilization measures for
disturbed areas and structural controls to divert runoff and remove sediments. Selected
controls must be per the Best Management Practices (BMP) outlined in the latest Drainage
Design Manual for Maricopa County Volume III Erosion Control (ECM).
Best Management Practices (BMPs) – Structural devices or non-structural practices that
are designated to prevent pollutants from entering into storm water flows, to direct flows of
storm water or to treat polluted storm water flows. The emphasis should be placed on
eliminating the source of pollutant(s). All selected BMPs details must be shown on the plan
sheets or included as part of the Storm Water Management Plan.
Sediment Basins - Show location of all temporary or permanent sediment basins to be
installed. Temporary basins may be substituted for permanent basins during grading phase
only. These basins must provide at least 3,600 cubic feet of storage for every acre of
contributing land.
Other Controls – The SWPPP must also include controls that address other potential
sources of storm water pollution, such as:
Construction site waste material storage.
Preventing offsite tracking of sediments and generation of dust.
Hazardous material storage (i.e., fuel, equipment oil, etc.)
Equipment maintenance/ parking areas.
Post-Construction – The SWPPP must include a description of storm water management
controls that will be installed to control pollutants after construction completion.
Future Activities – The SWPPP shall address all grading activities to be performed on any
site that is part of the “greater common plan or development” (i.e., construction of
individual lot(s) within a subdivision).
Location of Controls – the BMPs selected for the site must be shown on the SWPPP,
including the location of each measure used for erosion and sediment control, storm water
management, and other pollution controls.
Inspection and Maintenance Plan – The SWPPP must contain a description of the
procedures that will be used to maintain the BMPs on site. The plan shall include an
inspection and maintenance checklist for each control measure. The checklist must address
specific items to inspect for and evaluation criteria.
Description of Controls – The SWPPP shall include a list of the BMPs to be used at the
site, describing each control and its purpose. Many of the BMPs selected from the ECM
already contain the descriptions and purpose.
Sequence of Major Activities – The SWPPP shall contain a sequence of major activities.
The sequence should address the installation of all controls, earth disturbing activities, and
stabilization activities, and the maintenance required for the controls. The sequence should
indicate, clearly, the order in which these activities will take place along with a proposed
timeline associated with each activity.
In developing a sequence of major activities, the following general principals should be
followed:
1. Install down slope and side slope perimeter controls before the land disturbing activity
occurs.
2. Cover or stabilize disturbed areas as soon as possible. (Under ADEQ’s general permit,
disturbed areas of the construction site that will not be re-disturbed must be stabilized
within 14 days of the most recent land disturbance).
3. Time construction activities to limit impact from seasonal climate changes or weather
events.
5
4. Delay construction of infiltration measures until the end of the construction project, if
possible. Otherwise, provide proper Storm Water Management Controls to eliminate

INTRODUCTION
The purpose of this document is to provide criteria for the preparation of Traffic Impact
Studies for new land developments or additions to existing developments and to establish
the report format for these studies.
STUDY REQUIREMENTS
A Traffic Impact Study prepared by a Registered Professional Engineer in the State of
Arizona is required when a proposed development is anticipated to generate 100 or more
trips per day or as the City deems necessary unless waived in writing by the City
Engineer. In some cases, the City may allow a Traffic Impact Study with a reduced
scope. If the Traffic Impact Study is waived, a Traffic Impact Statement is required that
includes (a) discussion of the site access(es), (b) the total vehicle trips that will be
generated by the development, using the Institute of Transportation Engineers (ITE) Trip
Generation publication (most recent edition), (c) effect of the improvements on the
surrounding area from a traffic standpoint and (d) an exhibit that shows the distances
between the proposed and existing driveways.
STUDY CLASSIFICATIONS
Traffic Impact Studies will be classified into three categories:
Category I-
Those developments that are estimated to generate 500 vehicle
trips or less during either of the a.m. or p.m. peak hours.
Category II-
Those developments that are estimated to generate more than 500
vehicle trips during either of the a.m. or p.m. peak hours but not
more than 1,000 peak hour trips.
Category III-
Those developments that are estimated to generate more than 1,000
vehicle trips during either of the a.m. or p.m. peak hours.
The developer should first estimate the number of vehicle trips that will be
generated by the proposed development and provide this information along with the other
suggested study elements of the Traffic Impact Study to the City for Review and approval
prior to the start of construction.
4
TRAFFIC STUDY ANALYSIS AND APPROACH
The following presents the specific items to be included in a Traffic Impact Study.
Study Area
a) All site driveways
All categories
b) All major intersections within 1 mile of the study site,
either signalized or un-signalized.
All categories
c) All driveways where traffic movements could be
affected by new driveway traffic movements.
All categories
d) Additional locations as requested by the reviewing
agency.
All categories
Study Time Frame
The study should include, as a minimum, an analysis of the expected traffic conditions
for the time period when the development is expected to open. The opening day
conditions should include all of the proposed development traffic as if the development
was fully completed and occupied.
Additional study years should be included as follows:
Category I:
Opening year and 5 years in the future.
Category II:
Opening year, 5 years and 10 years in the future.
Category III: Opening year, 5 years, 10 years and 20 years in the future.
The study for phased construction developments should include an analysis for each year
that planned new phased construction is to be started. In addition, the required 5, 10 or 20
year analysis after the start of the last phase of the development as stated above for the
specific categories.
Analysis Time Periods
The study should include an analysis of the impact of the development traffic for the
typical adjacent street peak hour conditions which normally occur within the time periods
from 6:00 to 9:00a.m. and 3:30 to 6:30p.m. on a typical weekday and an analysis of the
impact of the development daily weekday traffic generated on the adjacent street system
and site driveways. In addition, if requested by the City, additional time periods and or
weekend analysis may be required in the study if the developer has unusual peaking
5
characteristics or if the adjacent non-site traffic conditions warrant an analysis of other
peak traffic time periods.
Data Collection
The traffic impact study should include information on the following existing and
proposed conditions within the study area:
a) Traffic Volumes
1. Existing and proposed traffic volumes for the adjacent existing and
proposed intersections and driveways to include daily weekday a.m. peak
hour and p.m. peak hour (and other time periods as noted in the previous
section). Daily traffic volumes should be provided as a 24-hour directional
roadway section count and peak hour volumes should be provided by
specific intersection or driveway turning movement directions.
2. Existing traffic volume data should be adjusted to average conditions
based on City adjustment factors or appropriate adjustment factors
available from other public agencies.
3. Projected traffic volumes should be based on available traffic projections
from the Maricopa Association of Governments (MAG), other appropriate
documented traffic projected sources or historical traffic volume trends.
Projected traffic volumes shall include adjustments, as necessary, to
reflect other adjacent future development.
b) Land Use
1. Existing and proposed land use in the study area should be discussed and
included in the study as it impacts the proposed development street system
or driveways.
c) Roadway Conditions
1. Existing and proposed roadway conditions shall be identified including
pavement type, width, traffic lanes, medians, curb and gutter, speed limits,
horizontal and vertical curvature and traffic control devices.
d) Crash Experience
1. Crash experience should be documented for the past 36-month time period
for the adjacent roadway system included within the study area.
6
Trip Generation
The trip generation for the proposed development shall be estimated using the latest
edition of Trip Generation published by ITE. Exceptions to the use of this document
must be approved by the City and may include actual traffic generation counts from a
similar existing facility having the same size and surrounding area characteristics or from
other recognized sources that provide trip generation data not included in the ITE manual.
If proposed within the Traffic Impact Study, adjustments to the site traffic generation
should be documented to reflect site traffic interaction, pass-by traffic, use of other
modes of transportation, carpooling or other means of trip reduction. Trip reduction
methods should be discussed with the City prior to use within the report.
Trip Distribution and Assignment
Site traffic shall be assigned to the proposed site driveways and street intersections
included within the study area based on an analysis of the market area for the proposed
development. The market area will vary based on the type and location of the
development. However, as a minimum, the following guidelines should be used:
● Residential trip distribution should be based on the locations of employment
and commercial attractions and the available street system.
● Commercial, industrial and office trip distribution should be based on the
surrounding population densities and the available street system.
The area to be constructed in the development of the site trip distribution should normally
be within a 10-mile radius of the study site. However, other conditions of the proposed
development, the adjacent street system and the location of site traffic attractors and
generators may indicate the need to expand or reduce the area of influence.
Traffic Analysis
The study should include the following minimum items for analysis.
a) Traffic flow conditions, including the level of service using the latest edition of
the Highway Capacity Manual (Special Report 209, Transportation Research
Board)
1. An analysis of the existing traffic conditions.
2. An analysis of the future non-site traffic conditions.
3. An analysis of the traffic conditions with the addition of site traffic.
7
b) Roadway capacity conditions using generally accepted daily volume traffic
demand compared to roadway cross sections.
1. Existing traffic conditions
2. Future non-site traffic conditions.
3. Future traffic conditions with the addition of site traffic.
c) Intersection and driveway traffic control device requirements using results of the
items below and the Federal Highway Administrations (FHWA) Manual on
Uniform Traffic Control Devices for Streets and Highways (edition adopted by
the Arizona Department of Transportation)
1. Existing conditions.
2. Future non-site conditions.
3. Future total traffic conditions.
d) Intersection and driveway geometrics using recognized accepted formulas with
documentation provided within the report.
1. Analyze adequacy or need for additional through traffic lanes or auxiliary
right or left turn lanes for existing, future non-site and future total traffic
conditions and include storage requirements.
2. Analyze potential conflicts of proposed driveway locations with existing
and/or proposed adjacent driveways or intersection traffic lane
configurations for the future total traffic conditions.
e) Crash summary and identification of trends and/or potential safety hazards.
f) Other analysis as requested by the City or as may be required due to the type and
location of the proposed development.
1. Weaving analysis.
2. Parking analysis.
3. On-site circulation including queuing analysis at major on-site turning
movement locations and for drive thru lanes. The effective length of a
vehicle shall be measured in increments of 25-feet. Drive thru
establishments shall be provided with adequate queue storage capacity to
accommodate normal peak queues for the specified land use.
8
4. Site access quantity, location and traffic lane configuration.
g) Mitigation measurements
All recommended on-site and off-site improvements required to mitigate projected
traffic congestion or safety issues shall be identified with the resultant traffic flow
conditions indicated for comparison to the “before conditions”.
