§ 10-1-1  PURPOSE OF ENGINEERING DESIGN GUIDELINES AND POLICIES.

     The purpose of the Engineering Design Guidelines and Policies (this Chapter or these Guidelines) is to provide both general information and specific design guidelines 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 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 Guidelines to establish a complete set of design criteria; however, certain guidelines must be followed to provide consistency for the sake of maintenance, repair or replacement.

(Ord. 1282, § 1.1, passed 11-7-2006)

§ 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.  Updates will be published and made available periodically.  The City Engineer may provide a "Memorandum of Clarification" to all Guidelines holders on an as-required basis.

     (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 (Vol. II, Appendix 10-B).  The physical limits of the Rural Area are shown on Apache Junction Standard Detail AJ-12.1.

          (3)     Portalis (Vol. II, Appendix 10-C). The physical limits of Portalis are shown on Apache Junction Standard Detail AJ-12.1.

(Ord. 1282, § 1.2, passed 11-7-2006)

§ 10-1-3  INTENT.

     These Design Guidelines and Policies 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.

(Ord. 1282, § 1.3, passed 11-7-2006)

§ 10-1-4  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 Guidelines 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 guidelines.  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 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.

          (4)     When washes cross a property, an erosion hazard 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.

     (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 City Engineer, all developments within the city shall be serviced by the Apache Junction Water Company 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 City Engineer, all developments within the city shall provide for the discharge of domestic and other liquid waste into the sewage system provided by Superstition Mountains Community Facilities District (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.

     (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 guidelines 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 (Vol. II, Chapter 2) and/or Zoning Ordinance (Vol. II, Chapter 1), the current adopted International Building Code, Standard Specifications, and these Guidelines, as appropriate.

     (F)     Order of precedence.  It is not intended by these Guidelines 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 Guidelines 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 Guidelines shall prevail.

     (G)     Definitions and abbreviations.  The words, abbreviations or phrases used in these Guidelines 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.

(Ord. 1282, § 1.4, passed 11-7-2006)

§ 10-1-5  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 Guidelines.

     (B)     All construction of public infrastructure shall be in accordance with the approved plans, the latest City of Apache Junction Engineering Design Guidelines and Policies (this Chapter), the Apache Junction Standard Details set forth in Vol. II, Appendix 10-D to this Chapter, the Uniform Standard Details and Uniform Standard Specifications published by the Maricopa Association of Governments (MAG), the 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:

          (1)     Conceptual site/improvement plans.

               (a)     A developer may prepare and submit a conceptual site/improvement plan for purposes of discussion with Development Services and Public Works.  This "courtesy review" would 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 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 1 city benchmark.  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 benchmark shall be verified by the construction contractor during construction.

          (3)     Right-of-way.  When required, the acquisition and dedication of new street right-of-way and/or easements (utility, drainage and the like) shall be determined and coordinated through the city.  Deeds containing legal descriptions and accompanying exhibits for these rights-of-way, easements, tracts and/or parcels used to dedicate or cause to be dedicated to the city shall be prepared and sealed in accordance with the requirements of the Arizona State Board of Technical Registration and submitted to the city for approval and recordation prior to final plan approval.

          (4)     Street lights.  Street lights are required on all public streets within or adjacent to the proposed development per city regulations.  Plans for these facilities must be included in the overall submittal.  Street lights are not required in the specially designated Rural Area.

          (5)     Utilities.

               (a)     All utility designs must be in accordance with city standards, utility company standards, the latest State and County Health Department requirements, and approved by each respective agency prior to the issuance of city permits.  The developer shall:

                    1.     Coordinate the plans with all of the appropriate utility companies; and

                    2.     Place a "utility coordination block" on the cover sheet showing the names of the utility companies, and the date plans were submitted to each company or agency.

               (b)     Utilities for new development shall be placed underground in accordance with Apache Junction City Code, Vol. II, Chapter 6, Landscaping.

               (c)     Existing and proposed locations must be shown on plans to reduce the possibility of conflict and damage.  Correcting conflicts shall be the responsibility of the developer.  All relocation costs must be borne by the developer.

               (d)     In the case of large projects where the improvements cannot be shown on 1 plan sheet, the plans must include a general Master Utility Plan for the development.  This Master Utility Plan shall appear on 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 sink 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, and building foundation 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 comments will be compiled and consolidated by the Apache Junction Development Services Department and returned to the developer.  All such comments shall be incorporated into the plans and reports by the developer for resubmittal.

               (b)     Water plans that are in the Arizona Water Company's jurisdiction will be submitted to Arizona Water Company for its review and approval.

               (c)     Sewer plans will be submitted to Superstition Mountains Community Facilities District for its review and approval.

          (8)     Plan approval.

               (a)     Final plan approval is required prior to the start of construction.  Plans are considered approved when all appropriate sign-offs have been obtained.

               (b)     Plan approval is valid for 1 year.

               (c)     If construction is not started within 1 year of the issuance of permit, the plans must be resubmitted for review and reapproval, and the appropriate fees must be re-paid.  The updated plans will be subject to review under the code in force at the time of the new review.

          (9)     Construction.

               (a)     Construction permits are required for each phase of each type of construction activity within the city.  Any contractor found working on a project without an official set of approved plans and permits shall discontinue work.  Prior to the issuance of a permit, the developer shall provide the appropriate assurance of construction for the off-site improvements per city regulations.

               (b)     The city's review of all NPDES submittals including NOI, NOT and SWPPP is intended as review only and does not constitute approval of the methods or plans for cleaning the stormwater and protecting the waters of the United States.  The contractor is solely responsible for insuring that all requirements of the Clean Water Act are strictly enforced.

          (10)     Preliminary and final plat.  Preliminary and final plat requirements, see Vol. II, Article 10-8 of this Chapter.

               (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 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 desirable as a safety measure.

          (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.

               (b)     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 T-configuration.  The sight visibility triangle, or sight triangle, consists of 3 sides that are formed by 2 intersecting access ways and a line connecting the 2 (see Apache Junction Standard Detail AJ-27.1).

     (C)     Sight distance.

          (1)     Adequate sight distance shall be provided at all intersections, alleys and driveways (see Apache Junction Standard Detail AJ-26.1).

          (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.

          (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 2-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.  Unusual conditions may cause cross-slope requirements to vary, but normally, the desirable cross-slope is 2%, with a maximum cross-slope of 3% and a minimum cross-slope of 1%.  Any deviation from the desirable 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 Vol. II, § 10-3-6(D) for street widening guidelines.

          (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 guidelines.

          (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, ease of maintenance and pleasing appearance.

               (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 4 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 guide traffic.

          (2)     The pavement section for tapers shall be per these Guidelines.  See Table 10-3.1 under 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.

          (6)     The 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.

          (5)     Utility adjustments and concrete collars shall be completed prior to application of surface treatment.

          (6)     A soil test and a street structural section recommendation by a qualified geotechnical firm shall be required unless the City Engineer gives written permission not to.

     (B)     Rigid pavement.  Rigid pavements, such as portland cement concrete, are generally not used for city streets.  If rigid pavements are used, each design must be approved by the City Engineer on an individual basis.

     (C)     Decorative pavement.

          (1)     The use of decorative concrete must be approved by the City Engineer.  Decorative concrete will not be placed in arterial through lanes.  When approved, it shall be constructed in accordance with MAG Standard Specifications Sections 340 and 725 (Class A concrete) with a minimum thickness of 8 inches.

          (2)     The use of interlocking paving blocks must be approved by the City Engineer.  When approved, they shall be installed in accordance with the manufacturer's guidelines.  In addition, a minimum of 25 paving blocks of the type installed must be deposited free of charge at the city's maintenance yard for future city maintenance operations.

     (D)     Miscellaneous pavement standards.

          (1)     For cases where the full depth of base course cannot be constructed due to insufficient cover over existing facilities, the city reserves the authority to approve equivalent alternate designs if justified.

          (2)     The minimum pavement cross-sectional requirement for temporary turnarounds, which are constructed at project phase lines, is 6 inches of aggregate base course over 6 inches of subgrade; see MAG Standard Specifications Sections 301, 310 and 702.  If the temporary turnaround is constructed at a project boundary, a surface course of 2 inches of asphaltic concrete is required in addition to the base and subgrade noted above; see MAG Standard Specifications Sections 321 and 710, without lime.

          (3)     Temporary pavement cross-sections shall consist of 2 inches of asphaltic concrete over 6 inches of aggregate base course over 6 inches of subgrade, see the same MAG Standard Specifications sections noted above.

          (4)     The edge of the temporary pavement and the perimeter of a paved temporary turnaround shall be constructed with a thickened edge per MAG Standard Detail 201, Type "B."

§ 10-3-6  STREET IMPROVEMENTS.

     (A)     Medians.

          (1)     Median widths.  Median widths (raised and not raised) are as shown on Apache Junction Standard Details AJ-20.4 and AJ-20.5.

          (2)     Median curbs.  Median curbs shall be installed per Apache Junction Standard Details AJ-20.4 and AJ-20.5.

          (3)     Median curb termination.

               (a)     Medians shall terminate in a bullet nose per MAG Standard Detail 223.  Concrete pavers may be used in lieu of concrete when approved by the City Engineer.

               (b)     At intersections, medians shall terminate at a point perpendicular to the curb return adjacent to the median's bullet nose per Apache Junction Standard Detail AJ-25.1 or as directed by the city.

          (4)     Median openings.

               (a)     Raised medians on major streets are provided to reduce conflicts and improve traffic flow.  Careful consideration should be given to requests for median cuts to ensure that the purpose of the median is not defeated by a proliferation of indiscriminate median cuts.

               (b)     There are 2 types of median cuts used in Apache Junction. 

                    1.     Full access.  The full access cut allows left turns from the street into a site as well as left turns from a site onto the street.

                    2.     Partial access.  The partial access opening allows left turns from the street into a site, but it prohibits left turns from a site on to the street.  The partial access opening allows fewer traffic conflicts and has a lower potential for accidents than the full access opening. 

               (c)     Median openings shall be designed per the following criteria.

                    1.  Median opening spacing is measured from the center of the median opening to the center of the adjacent median opening or intersection.

                    2.     In general, full access median cuts may be provided at 1/6-mile or 880-foot points along an arterial street.  Additional median openings are allowed but should be the partial access type.

                    3.     A median cut closer than 880 feet to an arterial-to-arterial intersection shall be the partial access type.

                    4.     Median cuts less than 660 feet from an arterial-to-arterial intersection are not allowed.

                    5.     Median cuts less than 660 feet from any signalized intersection or an intersection likely to be signalized are not allowed.

                    6.     Median cuts less than 880 feet from a freeway interchange generally are not permitted, although each case will be evaluated based on the configuration of the particular interchange.

                    7.     Adjacent median cuts should not be so closely spaced as to eliminate all of the area available for landscaping in the median.

                    8.     Left turn storage shall be provided for both directions on the major street.

                    9.     There may be unique geometric conditions at some locations that would affect the ability to provide a median cut.  Variations from these Guidelines may be appropriate depending on the particular design features of the street under consideration.  Variations may be approved by the City Engineer.

               (d)     The design and construction of median openings for private businesses shall be the responsibility of those establishments, subject to approval by the city.

          (5)     Median landscaping.

               (a)     Landscaping within a median shall be approved by the city's Parks and Recreation Department. 

               (b)     Landscaping within a median along a public street shall be maintained by the city.

     (B)     Curbs and gutters.

          (1)     Vertical curbs.

               (a)     Vertical curbs are required for all streets except local residential and the designated special area:  Rural Area.

               (b)     The vertical height of the curb shall be 6 inches on arterial or collector streets unless otherwise approved to match existing conditions. 

               (c)     Installation shall be per MAG Standard Detail 220, Type "A" or MAG Standard Detail 222, Type "A." 

               (d)     Vertical curbs shall be 6 inches at all medians and edge of roads with landscaping, equipment or vertical structures. 

               (e)     Six-inch vertical curb will be used at all curb returns on public local residential street intersections.

               (f)     Six-inch vertical curb will be used at all curb returns on public local residential street intersections with collector or arterial streets.

          (2)     Roll curbs.  Roll curbing is required for public local residential streets except where vertical curb is required (curb returns and the like) and is to be constructed in accordance with MAG Standard Detail 220, Type "C" or "D."

          (3)     Ribbon curbs.  Where ribbon curb is needed and approved by the City Engineer for public streets, the installation of the ribbon curb is to be per MAG Standard Detail 220, Type "B."  Transition from vertical curb and gutter or roll curbing to ribbon curb shall be with a curb termination.  Installation of the curb and gutter transition is to be per MAG Standard Detail 221.

          (4)     Curb returns.  All curb returns shall be constructed with vertical curb.  Curb returns shall have a minimum drop of 0.20 of a foot around the return.  Maximum drops shall not exceed 5% along the face of the curb at the sidewalk ramp.  See Table 10-3.2 for minimum back of curb radii for curb returns at intersections.

          (5)     Height transitions.  Transitions in curb height shall occur within the curbing at an intersection between curb returns or between the wings of a driveway (from 6 inches to 4 inches for example).

          (6)     Curb removal and replacement.  If existing curb and gutter must be removed and replaced, the existing asphalt pavement must be sawcut and removed to a minimum width of 2 feet from the lip of the new gutter.  Replacement of asphalt pavement shall match existing asphalt and base thickness at a minimum.

          (7)     Valley gutters. Valley gutter and aprons, where required, are to be installed per MAG Standard Detail 240.  Valley gutters are to have a minimum drop across the intersection of 0.25 foot.  Valley gutters and aprons shall be constructed with Class "A" concrete.

               (a)     Transverse valley gutters are prohibited from being used within the city.  If a transverse valley gutter is proposed, it must be approved by the City Engineer.

               (b)     Asphalt valley gutters are not allowed on public streets.

               (c)     Locations of valley gutters.  Valley gutters may only be used across collector streets, and local residential streets.  Exceptions must be approved by the City Engineer.

     (C)     Turning lanes.  A separate turning lane permits separation of conflicting traffic movements and removes turning vehicles from the intersection area.  Right-turn lanes shall be provided on major arterial streets at all street intersections, and at driveways where warranted.  For left-turn lanes at signalized intersections, dual turn lanes should be considered when the turn volume exceeds 200 vehicles per hour, the opposing through volume exceeds 1,000 vehicles per hour, or the delay to left turning vehicles exceeds 45 seconds.  Abrupt reduction of alignment and sight distance standards should be avoided.  The minimum length of these lanes must be approved by the City Engineer and are:

     (D)     Street widening.

          (1)     Projects widening existing pavement are required to sawcut and remove a 2-foot minimum section of the existing pavement continuous along the edge of the existing pavement.

          (2)     Projects that are required to widen existing pavement shall provide on the plan and profile sheets, as a minimum, existing elevation, grades at the centerline, sawcut line and gutter line at 50-foot intervals, unless a smaller interval is required by the Development Services Engineer.

          (3)     Also the plan sheets shall show the existing cross-slope from the existing centerline of the street to the sawcut line and from the sawcut line to the lip of proposed gutter at the same 50-foot intervals.  The existing and proposed cross-slopes are to be within 1% to 3% with a desired 2%.  The existing pavement must be sawcut to a line that achieves the 1% to 3% or rebuilt from the street centerline.

          (4)     When existing paving has been installed without surface course, the developing project shall install surface course to the centerline.  The surface course shall be tapered beyond the centerline to provide a smooth transition.  The Development Services Engineer shall assess the amount of tapering required to make a smooth transition to the existing pavement.

          (5)     The developer's engineer will be required to investigate existing pavement for composition, structural capacity and stability.  If after the developer's engineer's investigation, the city determines the existing pavement section is below current standards, the developer's engineer shall call out a sawcut at the construction centerline and replacement of the existing pavement with new pavement per city guidelines.

     (E)     Partial street and half-street improvements.

          (1)     Generally, a developer is required to construct the full street cross-section for the streets internal to the development and a portion of the streets surrounding the development.  For partial or half-street designs, a 24-foot minimum width from lip of gutter to the edge of the asphaltic pavement and a striping plan is required.  The partial street construction standards are per Apache Junction Standard Detail AJ-21.1.

          (2)     For all streets, pavement tapers shall be constructed to provide transitions between newly constructed and existing roadway sections as deemed necessary by the Development Services Engineer.

     (F)     Public alleys.

          (1)     New residential alleys are not allowed in Apache Junction.

          (2)     Commercial alleys are to be 24 feet wide.  Surfacing is to be per MAG Standard Detail 202.

          (3)     Projects that have an alley system within or contiguous to the project which will be used as a primary means of access shall have an alley that is a minimum of 24 feet wide and paved.  Paving shall be per MAG Standard Detail 202.

          (4)     Projects that have an alley system within, or contiguous to the project, which will not be used as a primary means of access, are required to surface the alley with a minimum of 6 inches of aggregate base course (ABC).   

     (G)     Sidewalks.

          (1)     Construction standard. Parkway, arterial, collector and local street classifications that have sidewalks shall comply with Apache Junction Standard Details AJ-20.1 through AJ-20.5 in addition to MAG Standard Detail 230 except as otherwise approved by the city.

          (2)     Sidewalk widths.

               (a)     Local street classifications require 4-foot wide sidewalks except in special designated area-Rural Area where no sidewalks are required.  See Apache Junction Standard Detail AJ-20.1 and AJ-20.6.

               (b)     Collector street classification requires a 5-foot sidewalk except in special designated area-Rural Area where no sidewalks are required.  See Apache Junction Standard Detail AJ-20.2 and AJ-20.7.

               (c)     Minor and major arterial street classifications require 6-foot wide meandering sidewalks except in special designated area-Rural Area where no sidewalks are required.  See Apache Junction Standard Detail AJ-20.3 and AJ-20.8.

               (d)     Principal arterial and parkway street classifications require 10-foot wide meandering sidewalks.  See Apache Junction Standard Details AJ-20.4 and AJ-20.5.

               (e)     Sidewalks on bridges are required to be a minimum of 8 feet in width.

          (3)     Width transitions. Sidewalk width transitions shall occur either in the curb return area or across a driveway.

          (4)     Location

               (a)     Sidewalks along collector, arterial and parkway streets shall be detached and linear at a distance as noted per Apache Junction Standard Details AJ-20.2 through AJ-20.5 or as specified by a technical review comment.

               (b)     Sidewalks along local streets shall adjoin the back of the curbing.

               (a)     Existing curb installation.  The installation of a sidewalk ramp in an existing curb shall be made by completely removing the existing curb and gutter.  The existing asphalt pavement shall be removed and replaced as noted in the section on curb and gutter (division (B)(6) above).  The sidewalk ramp will be constructed per MAG Standard Detail 231, Type "A."

               (b)     Tee intersections.  Sidewalk ramps per MAG Standard Detail 233 shall be installed on the perpendicular side of the street at the tee intersections and shall be aligned with 1 of the curb returns on the opposite side of the street.  Where roll curb is constructed, the sidewalk ramp shall be per Apache Junction Standard Detail AJ-22.1.

               (c)     Existing intersections.  Projects that adjoin or include an existing public street intersection in which sidewalk ramp(s) are not existing are required to install the necessary ramp(s) in order to comply with ADA requirements.

     (H)     Driveways.  All driveways within public rights-of-way shall be designed and installed per the following:

          (1)     Residential lots.  Residential lots where the sidewalk is adjoining the roll curb, the driveway shall be installed per Apache Junction Standard Detail AJ-23.1.

          (2)     Commercial and industrial properties.  Commercial and industrial driveways shall be installed per Apache Junction Standard Detail AJ-24.1. 

          (3)     Existing curb installations.  The installation of a driveway in an existing vertical curb shall be made by the complete removal of the curb and gutter.  The existing asphalt pavement shall be removed and replaced as noted in the section on curb and gutter (division (B)(6) above). The driveway shall be constructed per Apache Junction Standard Detail AJ-24.1.

          (4)     Driveway location limitations.

               (a)     New access.  A new access driveway will not be allowed (measured to the driveway centerline):

                    1.     Within 30 feet of any commercial property line, except when it is a joint-use driveway serving 2 abutting commercial properties and access agreements have been exchanged between, and recorded by, the 2 abutting property owners;

                    2.     When the total width of all driveways serving a property exceeds 50% of the curb line frontage;

                    3.     Within 50 feet of the right-of-way line of an intersecting non-arterial street;

                    4.     Within 100 feet of the right-of-way line of an intersecting arterial street; or

                    1.     Residential properties that have frontage on a local street as well as on an arterial or collector street shall only access the local street.

                    2.     In some instances, residential parcels fronting only on an arterial or collector street may be given access if alternate public access is not available and is approved by the City Engineer.  When such access is allowed, the driveway shall be circular or it shall have a turn-around area to ensure that there is no need for backing onto the street.

          (5)     Locations delineated.

               (a)     Commercial and industrial. Commercial and industrial driveway locations shall be delineated on the improvement plans and installed as part of the original curb and sidewalk construction per Apache Junction Standard Detail AJ-24.1.

               (b)     Residential.  Residential driveway locations not delineated on the construction plans shall be identified before the curb, gutter and sidewalk is constructed and approved by the city's Inspector.  The driveways shall be constructed per Apache Junction Standard Detail AJ-23.1.

     (I)     Deceleration lanes.  Deceleration lanes may be required on streets in conjunction with driveways and may require additional right-of-way.  The location and lane length shall be determined on a case-by-case basis and shall be approved by the Development Services Engineer.

     (J)     Bikeways, lanes and paths.

          (1)     Bikeways and bike paths separate from the paved roadway require a minimum of 5 feet for 1-way travel and a minimum of 10 feet for 2-way travel.

          (2)     Each bike lane within the paved roadway requires a minimum of 4 feet of additional pavement.  See Apache Junction Standard Details AJ-20.2, AJ-20.3, AJ-20.7 and AJ-20.8.

§ 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.

(Ord. 1282, § 4.1, passed 11-7-2006)

§ 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 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 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 1 dry 12-foot driving lane in each direction.

          (2)     One hundred-year stormwater runoff.

               (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 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 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 hazard area shall conform to the requirements of the latest city floodplain management ordinance.  See Vol. II, § 10-4-13 and Vol. II, Chapter 5.

     (E)     Conditions for developing property in flood areas.

          (1)     (a)     Existing washes are not to be filled or altered without a city-approved engineering 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:

                    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;

                    3.     Local floodplains associated with washes and/or sheet flow having a 100-year peak discharge of 50 cfs or more;

                    4.     Areas within the erosion hazard setback of a watercourse;

                    5.     All floodplains/flood-prone areas and erosion hazard setbacks identified on previously and subsequently recorded subdivision plats; and

                    6.     All floodplains/flood-prone areas and erosion hazard setbacks identified on previously and subsequently drainage studies commissioned by the City Engineer.

               (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 1 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 1 foot is required.

               (b)     A subdivision of 5 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.

               (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 2 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 1 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 1 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.

          (11)     Refer to the city's floodplain management ordinance set forth in Vol. II, Chapter 5 for further information.

     (F)     Stormwater collection and retention plan.  A conceptual stormwater collection and retention plan and a preliminary drainage report shall be submitted to the city with a preliminary plat or site development plan, and shall be approved prior to the approval of the plat or plan.  Drawings, plats, plans and the like shall comply with the city standards, set forth in Vol. II, § 10-4-4(A).

     (G)     Drainage report.  A drainage report shall be submitted to the city wherever development and/or grading is proposed within the city limits.  DEVELOPMENT shall mean any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling.  See Vol. II, § 10-4-4(B).

(Ord. 1282, § 4.2, passed 11-7-2006)

§ 10-4-3  STORMWATER MASTER PLAN.

     The city's "City of Apache Junction Stormwater Master Plan," dated January 2002, shall be used as the basis for any off-site drainage flows.  This Master Plan can be viewed at the City Engineer's office.

§ 10-4-5  HYDROLOGY.

     (A)     General comments.  This section describes the city's policies concerning hydrologic analysis procedures to be used in the city for the planning and design of drainage and flood control facilities and the preparation of accompanying drainage reports.  This section contains recommended procedures, equations, data and basic assumptions which the planner or designer is generally required to use.  If a situation is encountered in which the use of other methods or data in addition to or instead of these are believed to be more appropriate, then the City Engineer should be consulted and advance approval must be received before using them.  When methods or data not described in this Chapter are used, the drainage report must include enough information to enable the city staff to fully evaluate the applicability of the methods and data.

     (B)     Basis of design.

          (1)     The Drainage Design Manual for Maricopa County, Volume I, Hydrology, Section 3, Rational Method, shall be used to determine peak discharges and volumes for design purposes for small, uniform, regularly shaped watersheds less than 160 acres.

          (2)     The Corps of Engineers' HEC-1 or HEC-HMS computer modeling is required for small watersheds that are non-uniform, irregular in shape, when routing of flows are necessary, or for areas larger than 160 acres.

     (C)     Study requirements.  A hydrology study shall be performed for each development within the city.  The study shall define the overall and sub-drainage areas.  It shall also determine appropriate hydrologic data for the following:

          (1)     Off-project areas. The drainage flows for each off-project drainage area tributary to the project shall be computed and submitted in summary form.  These off-site flows will be based on the City of Apache Junction Stormwater Master Plan dated January 2002 (adopted in Vol. II, § 10-4-3) or from consultant's computations where the Master Plan does not cover.

          (2)     Project sub-basins. The project shall be divided into sub-basins tributary to appropriate design points.  The pertinent hydrologic data shall be computed for each and submitted in summary form.

          (3)     Appropriate design points. APPROPRIATE DESIGN POINTS are those points wherein the peak flow rates, or other pertinent data, are needed to determine flow capacity requirements, inflow-outflow relationships and the like.  These points would include but not necessarily be limited to the following: inflow-outflow points of retention/detention basins, up and/or downstream ends of culverts; intake points for storm drains (e.g., inlets, catch basins, scuppers and the like); points immediately upstream and downstream of channel junctions and/or street intersections; others as may be necessary to give a complete hydrologic picture and allow a thorough hydraulic evaluation and/or design of the drainage system.

§ 10-4-8  OPEN CHANNELS.

     (A)     Natural channels. Whenever possible and appropriate, it is the city's preference that existing natural drainage channels be left in a natural state.  When this is the case, a drainage easement or right-of-way shall be dedicated over the 100-year floodplain of the natural drainage way.

     (B)     Man-made channels.  When man-made channels are required, the emphasis would be placed on a "natural" appearance.  Side slopes 6:1 or flatter is preferred with "natural" vegetation planted per the city's Parks and Recreation Department requirements and approval.

          (1)     Design criteria.

               (a)     Open channels.  Open channels are not allowed in the city right-of-way.  Open channels shall be designed to convey at least the 100-year peak discharge within the main channel.

               (b)     Channel details.  Channel lining, freeboard, toe protection, under drains, design velocity, drop structures and the like shall be as shown in the FCDMC Drainage Design Manual, Volume II, Hydraulics.

               (c)     Hydraulic capacity.  The capacity of the drainage channel shall not be impeded or diminished by the lining or landscaping materials.  The conveyance of the historical flows (Qs) shall be substantially maintained.

               (d)     Maximum velocities/erosion protection.  In general, the maximum velocity shall not exceed the scouring velocity of the soil (with natural cover).  When the scour velocity is exceeded, additional erosion protection shall be provided.  The protection may consist of 1 or more of the following:

                    1.     Concrete/gunite lining reinforced with 12 gauge, 4-inch by 4-inch welded wire fabric reinforcement;

                    2.     Natural stone grouted rip-rap 4-inch to 12-inch diameter stones - leave a minimum 1/4 diameter exposed, maximum 1/2 diameter exposed;

                    3.     Check dams at 3-foot elevation intervals; or

                    4.     Dumped rip-rap of sufficient size and depth with calculations showing size and depth.

               (e)     Side slopes.  Channels shall have side slopes that are approved by the city.

               (f)     Channel safety.  Channels adjacent to pedestrian walkways (which is not limited to concrete sidewalks), whether located within public right-of-way or on private property shall have safety hand railings per MAG Standard Detail 145 or an equivalent design.

          (2)     Channel types.  The following types of channels are acceptable for use, and can be applied individually or in combinations.

               (a)     Concrete lined. Where used, these types of channels shall have a 4-inch gunite or concrete lining reinforced with 12 gauge, 4-inch by 4-inch welded wire fabric reinforcement.

                    1.     A natural coloring or additive may be allowed or required in some areas.

                    2.     Landscaping adjacent to the channel on both sides is required.

               (b)     Desert landscaped.  Where desired or applicable, landscaped channels can be constructed subject to the following:

                    1.     Maintenance of the channel is considered (e.g., 8-foot bottom provided where necessary).

                    2.     Side slopes can be landscaped with appropriate trees, shrubs and rock features which do not impede with the function of or the maintenance of the channel.

                    3.     Appropriate roughness coefficients (N-values) shall be used in sizing the channel.

                    4.     Appropriate materials as approved by the city shall be used as a channel liner.  The engineer shall take into consideration the potential for erosion and maintenance.

               (c)     Soil cement lining.  The use of soil cement requires special approval by the city, and where approved, this type of channel shall utilize native soils to achieve an integral character with the surrounding area.

          (3)     Dip sections.

               (a)     The design of public streets to create a dip section in which to channelize the stormwater flows of the design storm across public streets is prohibited except where specifically approved by the City Engineer and in the specially designated Rural Area (see 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 8-foot design width shall be used and must be approved by the City Engineer.  Mid-block valley gutters should be avoided.

          (5)     Maintenance.

               (a)     Access.  Open channels to be properly maintained should provide reasonable access for maintenance.  Minimum width of access should be 8 feet.  Spacing between vehicular access points should be a maximum of 1/2 mile.  A minimum of 1 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.

                    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;

                    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 1 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)

               (b)     South of Baseline Avenue:

          VR=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 Design Engineers shall denote on the master drainage map the actual or effective drainage area.  If portions of the project cannot 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 property owner 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 will issue letters of acceptance for maintenance of any public facilities.

     (D)     Grading.

          (1)     Depths.

               (a)     Retention basins are not permitted within the city right-of-way.  Where unusual circumstances are encountered, retention basins may encroach in city right-of-way 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 right-of-way and shall not exceed 1.5 feet of water depth within the city right-of-way unless there is a fence or other similar protection to restrict access to the area.

               (b)     The overall average depth shall not exceed 3 feet without authorization of the city.  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.

               (c)     While it is the city's intent that the "average" depth not exceed 3 feet, it is also the city's intent that the basins be contoured to present an aesthetically pleasing appearance.  Therefore, up to 25% of the bottom area may be up to 4 feet deep.

               (d)     In no case shall the depth exceed 1.0 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 Design Engineer shall endeavor to 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 Guidelines 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 5 feet each way of the "PI."

               (d)     All landscaping within city right-of-way, easements or dedicated tracts shall be approved by the City Parks and Recreation Department.

     (E)     Retention/detention in parking lots.

          (1)     Retention/detention in parking lots of multi-family developments is not allowed.  All retention/detention of such developments shall be in landscaped areas.

          (2)     Retention/detention of runoff in parking lots of industrial/commercial developments is allowed subject to the following guidelines:

               (a)     No more than 50% of the required storage volume may be retained/detained in parking areas.  The balance shall be provided in landscaped areas.  The tributary areas to each basin shall be noted 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 6 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.

          (1)     Off-project flows which historically flowed through the project may be routed through the project.  Off-site runoff volumes shall not be allowed across private lots, streets or public/private access ways.

          (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 rights-of-way nor into public easements.  If necessary, the developer shall relocate conflicting utilities into a new dedicated easement.

          (3)     The top of the retention/detention facilities (e.g., freeboard elevation) shall be at least 4 horizontal feet from any building or public roadway.

          (4)     Retention/detention facilities shall not be located within 20 feet of an active septic system nor within 100 feet of an active water well.

          (5)     A minimum 3 feet of cover (from the bottom of the basin to the top of the pipe) shall be maintained over water and sewer service lines.

     (I)     Disposal/discharge.

          (1)     All retention/detention facilities shall have a positive method of disposing of retained/detained runoff waters.  All water so retained/detained shall be disposed of within 36 hours.  Public streets are not considered an acceptable outlet for disposal of retained/detained runoff, however are considered an acceptable outlet for overflow.  Only under special circumstances with prior city approval should pump disposal methods be used.

          (2)     The minimum allowable pipe size for primary outlet structures is 12 inches.  A headwall (MAG Standard Detail 501-4) and an access barrier (Apache Junction Standard Detail AJ-50.1) shall be constructed at the outlet.

          (3)     Acceptable methods of disposal of accumulated stormwater runoff are:

               (a)     Positive gravity outlet.

                    1.     Surface infiltration. A percolation test is required in each retention basin location to determine natural percolation.  Test results shall be submitted to the City Engineer for approval of the retention basin(s).

                    2.     Drywells.

                         a.     Drywells are permitted when no other means of disposal are available.  Infiltration into the drywell cannot be considered to reduce the size of the retention area.

                         b.     The property owner of record shall be responsible for the design, performance, operation or maintenance of drywells used with on-site retention.

                         c.     Drywells must penetrate at least 10 feet into a permeable stratum and a percolation test must be carried out on the drywell before acceptance.  The percolation test results are to be filed with the Development Services Engineer.

                         d.     Drywells shall comply with the Arizona Department of Environmental Quality (ADEQ) publication Guidance for Design, Installation, Operation, Maintenance, and Inspection of Drywells and the additional requirements described herein.  A copy of the application for registration by ADEQ of the proposed drywell(s) shall be submitted prior to approval of grading plans.

                         e.     Multiple drywell installations shall be located a minimum of 100 feet apart, unless waived by the City Engineer, and a minimum of 20 feet away from a basin inlet.

                         f.     All drywells draining runoff from more than 1 acre of pavement are to be a dual chamber type similar to the MaxWell dual chamber drywell.

                         g.     For any project involving hazardous materials, including fuels, the drywell must include the "Envibro" Drainage System or equal.

                         h.     Drywells shall be located a minimum of 100 feet away from water wells and underground storage tanks (except stormwater underground storage tanks).

                         i.     Top of the drywell grate shall be set 2 inches above the bottom elevation of the retention basin.

                         j.     Number and type of drywells are to be called out on the engineering plans.

                         k.     Each drywell will be percolation tested after installation and a 50% value of its disposal rate shall be used, up to but not exceeding 0.5 cfs.  The percolation test results are to be submitted to the Development Services Engineer with the final as-built drawings of the Stormwater Collection and Retention Plan.

                         l.     Drywells which encounter perched water shall be sealed in the perched water zone of the well.

                         m.     All drywells shall be registered with the ADEQ and constructed by an ADEQ licensed contractor.  The approved drywell registration shall be submitted to the city by the developer or his or her engineer at the time as-builts are submitted.  A tabulation showing drywell number, registration number, and percolation rate will be added to the grading plan coversheet before submitting as-builts.

                         n.     The property owner of record shall be responsible for the design, performance, operation and maintenance of drywells used with on-site retention.

                         o.     Drywells that cease to drain a project area in a 36-hour period shall be replaced by the maintenance authority with new ones.

                         p.     Drywells are not to be located within public street right-of-way or private street roadway tracts unless authorized by the City Engineer.

                    3.     Storm drain discharge.  Discharge to an existing storm drain with a maximum discharge of 1 cubic foot per second.  A waiver is required.

                    4.     Drainage channel discharge. Discharge to a drainage channel either natural or man-made of sufficient capacity to convey the anticipated flows from the tributary drainage area.  A waiver is required.

                    5.     Prohibited discharge. Water cannot be discharged into a city street, gutter or alley.

               (b)     Pump station (waiver required).

                    1.     Permitted direction:

                         a.     To an open channel, either natural or man-made;

                         b.     Subsurface direction to a nearby storm sewer system with a maximum discharge of 1 cubic foot per second; or

                         c.     Surface to a storm sewer system if pumped water can be discharged directly into a catch basin or other inlet.

                    2.     Water cannot be discharged into a city street, gutter or alley.

                    3.     Pump stations shall comply with the requirements of Chapter 9 of Volume II of the FCDMC Drainage Design Manual, except as noted below.

                         a.     Pumping facilities shall be set at an elevation at or above the anticipated level of the 100-year event, considering that a total power failure may occur.

                         b.     Pumps shall be capable of handling solids up to a maximum of 3 inches.

     (J)     Nuisance water.  Each basin, particularly those used as a park, shall be graded such that there are 1 or more "sump" areas wherein runoff from the more frequent storms and nuisance runoff may be retained/detained without flooding the balance of the basin, with preference to surface percolation.

     (K)     Embankments.

          (1)     Detention or retention facilities should be constructed below the natural ground surface.

          (2)     The use of embankments to impound stormwater runoff requires prior approval by the Development Services Engineer.  Embankments become small dams that can be a serious potential downstream flood hazard.

          (3)     If approval is obtained, all the design requirements shall comply with Section 8.2.3, Embankment Design Criteria, of Chapter 8 of Volume II of the FCDMC Drainage Design Manual.

          (4)     The owner/developer must provide the city with as-built certification by a State of Arizona registered geotechnical or civil engineer experienced in dam technology, that the embankment was designed and constructed properly, is stable and will safely impound the design volumes of water.

     (L)     Underground retention storage requirements.

          (1)     Underground retention shall only be considered in commercial and industrial zoned areas.

          (2)     Each request for underground storage will be evaluated on an individual basis and permitted if approved by the Development Services Engineer.

          (3)     The following guidelines are not meant to be exclusive and, based on the type of underground storage approved, may require additional data and details be submitted to the city.

               (a)     Installation of CMP shall be in accordance with MAG Standard Specification No. 621, MAG Standard Detail 510 and a note on strutting spacing, if required, demonstrating that they are within manufacturer's specification and recommendation for installation.  Excavation, bedding and backfill shall be in accordance with MAG Standard Specification No. 601 and material per MAG Standard Specification No. 760;

               (b)     Provide the depth of groundwater and the depth of the proposed installation.  Provide soil boring results to at least 10 feet below the bottom of the proposed drywell;

               (c)     Demonstration of a 50-year life of the installation (lining and coating must be specified).  Aluminized CMP is usually good for more than 50 years depending on the soil chemistry;

               (d)     Traffic/load bearing capacity of the installation. Pipe gauge and corrugation size of CMP and D-load for RCP must be specified;

               (e)     The storage pipe must drain into a dual chamber drywell.  Include a detail of how the installation will be drained into the drywell.  The standard drywell detail does not address anything other than normal installation.  The sedimentation chamber and drain must be lower than the tank drain so the tank drains completely.  The system must drain within 36 hours;

               (f)     Provide a backfill detail.  Include material and compaction requirements, particularly under the haunches and to the springline of the pipe;

               (g)     Provide a minimum 30-inch diameter manhole shaft at each end of underground pipes up to 150 feet in length.  Underground pipes longer than 150 feet require an additional minimum 30-inch manhole shaft every 150 feet or fraction thereof.  All manhole shafts shall be equally spaced no more than 150 feet measured from center to center.

                    1.     A 30-inch manhole frame and cover can be used at grade with a concrete collar where subject to wheel loads.  Provide assurance that the pipe will structurally accommodate the manholes where there is traffic loading on the manhole.

                    2.     The manhole shaft is to be 30 inches in unobstructed diameter.  No projections or obstructions are permitted into the manhole shaft.  If the manhole shaft is to be provided with a ladder, the distance from any part of the ladder measured on the side of the ladder to the opposite wall of the manhole shaft shall not be less than 30 inches.  This may result in the necessity of a larger diameter manhole to accommodate a ladder.  Show a detail of how the ladders are to be anchored.  Specify material to be used for the ladders in order to assure a 50-year life.

               (h)     Provide assurance that the material used for the piping is suitable for the site's soil (letter from the Soils Engineer);

               (i)     Specify water-tight manufactured joints;

               (j)     Provide end walls for pipe per manufacturer's recommendation with a detail or MAG Standard Detail 427;

               (k)     Cover to be 3 feet minimum in traffic areas (or manufacturer's recommendation); and

               (l)     RGRCP is suggested for strength and durability.  Structural strength calculations based on subgrade capacity are required in areas subject to wheel loads.

          (4)     The above requirements are to be shown or specified on the plan or otherwise satisfactorily addressed.  The requested assurances are to be provided for the city's project file.

     (M)     Operation and maintenance.

          (1)     Maintenance of on-site detention or detention facilities within the city shall be the responsibility of the property owner or the subdivision's homeowners' association.

          (2)     All retention basins that will be maintained by the city shall be improved by the developer per city guidelines for retention basin development and installed prior to the city's acceptance of the retention.  Retention basins, when not privately maintained, shall be dedicated to the city in fee title as stormwater retention basins or drainage rights-of-way.  In the case where private retention basins receive water, other than that which falls upon the property and adjacent streets and/or alleys, the areas shall be designated as easement areas for retention purposes and shall have a recorded restrictive covenant requiring perpetual maintenance.

     (N)     Retention basins within SRP transmission line rights-of-way.

          (1)     Retention basins are to be designed to the latest SRP's requirements.

          (2)     Developer shall submit drawings to the city and SRP for approval. SRP will consider both existing and planned future power facilities in their review.  SRP approval letter shall be forwarded to the city 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 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.  Private easements and covenants shall be prepared and recorded by the developer or representative after review and approval of the associated documents.

     (D)     It is the developer's or property owner's responsibility to execute or cause the execution of the legal documents.  The developer or engineer shall return the executed documents 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 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.

(Ord. 1282, § 4.11, passed 11-7-2006)

§ 10-4-12  CONSTRUCTION AND INSPECTION.

     (A)     City policy requires that a responsible professional (e.g., civil engineer of record, land surveyor and the like) 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.

     (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.

(Ord. 1282, § 4.12, passed 11-7-2006)

          (11)     Prohibits the placement of new manufactured homes within regulatory floodways;

          (12)     Variances:

               (a)     Granting a variance is generally limited to lot sizes of less than 1/2 acre.

               (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 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.

          (3)     Confirm the lowest floor (including basement) is elevated or floodproofed to 1 foot above the base flood level (additional 1 foot freeboard flood elevation is recommended).

          (4)     Confirm watercourses enter and leave areas to be developed in their natural locations, and that flows or highwater elevations are not increased to the detriment of upstream and downstream properties.

          (5)     Ensure that hydrologic data is presented in accordance with the guidelines found in this article.

          (6)     Refer to and comply with provisions of Vol. II, Article 5-1, Floodplain Management.

§ 10-A-1  GENERAL COMMENTS.

     This Appendix 10-A describes the Engineering Design Guidelines for the special designated area known as the Downtown Area and the Central City District (CCD) zoning classification.

(Ord. 1282, Appendix A § 1, passed 11-7-2006)

§ 10-A-2  INTENT.

     The Downtown Area and its CCD zoning classification will be a mixed-use area that will include commercial and residential in a walking environment.

(Ord. 1282, Appendix A § 2, passed 11-7-2006)

§ 10-A-3  LOCATION.

     The Downtown Area and its CCD zoning classification is shown on Apache Junction Standard Detail AJ-12.1.

(Ord. 1282, Appendix A § 3, passed 11-7-2006)

§ 10-A-4  DESIGN GUIDELINES.

     The Design Guidelines are as detailed in the City of Apache Junction's Commercial Design Guidelines.

      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."

(Ord. 1282, Appendix B § 1, passed 11-7-2006)

§ 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.

(Ord. 1282, Appendix B § 2, passed 11-7-2006)

§ 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 right-of-way 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.

     (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.

      10-C-4     Design guidelines

§ 10-C-1  GENERAL COMMENTS. 

     This section describes the Engineering Design Guidelines for the special designated area known as “Portalis.”

(Ord. 1282, Appendix C § 1, passed 11-7-2006)

§ 10-C-2  INTENT.

     Portalis 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 and a good lifestyle.

(Ord. 1282, Appendix C § 2, passed 11-7-2006)

§ 10-C-3  LOCATION.

     Portalis is shown on Apache Junction Standard Detail AJ-12.1.

(Ord. 1282, Appendix C § 3, passed 11-7-2006)

§ 10-C-4  DESIGN GUIDELINES.

     (A)     Street section and right-of-way requirements.

          (1)     The principal arterial and parkway roadways are shown in the Portalis Master Street Plan prepared for Arizona State Land Department by URS.  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 Portalis including 2 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.

          (2)     On-site area stormwater management will need to meet the requirements of this Engineering Design Guidelines and Policies, Vol. II, Article 10-4.

          (3)     A number of washes in the Portalis 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.
