A.SPECIALLY DESIGNATED AREAS The specially designated areas are included as individual separate elements of this manual and are as follows: 1.Downtown Area (Appendix A) a.The physical limits of the Downtown area are shown on Figure 1-1. 2.Rural Area (Appendix B) a.The physical limits of the Rural area are shown on Figure 1-1. 3.Lost Dutchman Heights Area (Appendix C) a.The physical limits of the Lost Dutchman Heights area are shown on Figure 1-1. City of Apache Junction Chapter 1 Introduction Engineering Design Guidelines November 2006 1 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 of Apache Junction, and such other agencies as may have jurisdiction. 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 insure 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 of Apache Junction 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 the said 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 4.2.A. I &2).Such retention/detention facilities shall be separate and City of Apache Junction Chapter 1 Introduction Engineering Design Guidelines November 2006 2 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 insure 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 Manuals 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 accepted 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 said system to and through the development as necessary to insure 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 insure 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 Mountain Community Facilities District.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 district'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 district's sewage system. City of Apache Junction Chapter 1 Introduction Engineering Design Guidelines November 2006 3 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 and/or Zoning Ordinance, the current adopted Uniform 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.

D.CONDUITS, SLEEVES OR CARRIER PIPES Projects that have parkway landscaping with irrigation lines under public streets shall install conduit sleeves for the irrigation line(s) prior to the paving improvements.All parkway landscaping shall be as directed and approved by the Apache Junction Parks and Recreation Department. E.SIGNAGE AND STRIPING All signage and striping shall be per the latest MUTCD and approved by the Development Services Engineer. 3.4 DESIGN GUIDELINES Street design will be in accordance with the following criteria, subject to the approval of the City Engineer.Geometric design standards not specifically included in this Standard will conform to the latest A Policy on Geometric Design of Highways and Streets,published by the American Association of State Highway and Transportation Officials (A.A.S.H.T.0.). A.STREET RIGHT-OF-WAY REQUIREMENTS The right-of-way requirements shall be as shown in Apache Junction Standard Details AJ-20.1 through AJ-20.8. Right-of-way widths in excess of the standard widths may be required in special circumstances such as when: City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 6 1.Cut or fill slopes cannot be confined within the standard width; 2.Minimum sight distance lines on horizontal curves are not within standards; 3.Minimum sight distances at intersections are not within the standards; 4.Auxiliary lanes are to be provided. B.INTERSECTIONS Although all intersections share certain common elements, they are not subject to generalized treatment. 1.Minimize Conflict To minimize conflicts and provide for anticipated traffic movements, each intersection must be evaluated with regard to its individual characteristics, and designed based on the following factors: a.Traffic factors such as capacities, turning movements, vehicle size and operating characteristics, vehicle speed, pedestrian movements, transit operations, and accident history. b.Physical factors such as topography, existing conditions, channelization requirements. 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. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 7 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 twenty-four (24) inches and six (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 three (3) sides that are formed by two (2) intersecting access ways and .a line connecting the two (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. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 8 D.STREET SLOPES I.Typical Street Cross -Slope Undivided streets should have a normal crown that is a two-way cross -slope with the cross-section high point on the street centerline.Divided streets should have cross -slope on each pavement section.The high point of each slope on each pavement section shall occur on the edge of the pavement nearest to the median.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 one-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 Street Widening, Section 3.6.D, for 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 then 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 of Apache Junction Engineering Inspector immediately preceding the concrete pour. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 9 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 said 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 ten feet (10') from back of curb, slopes of 4:1 or flatter shall be provided. b.Steeper slopes may be approved in areas more than thirty feet (30') from back of curb when soils are not highly susceptible to erosion, or when a cut is not more than four feet (4') vertical.Cuts or fills greater than four feet (4') vertically shall be approved by the City Engineer. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 10 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. Table 3.1 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: 2 WXSa.When the design speed is 40 mph or less:IL = 60 b.When the design speed is 45 mph or greater:TL = WxS TL =Taper Length in Feet S =Design Speed in Miles Per Hour.The design speed is five (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 fifty -feet (50') minimum. However, there may be some instances when more than fifty -feet (50') 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. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 11 3.5 STREET STRUCTURAL SECTION (AGGREGATE BASE, ASPHALT BASE COURSE AND ASPHALT SURFACE COURSE) A.FLEXIBLE PAVEMENT The flexible pavement street structural section for public streets shall be the minimum depths shown below.

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. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 13 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". 3.6 STREET IMPROVEMENTS A.MEDIANS I.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 insure that the purpose of the median is not defeated by a proliferation of indiscriminate median cuts. b.There are two (2) types of median cuts used in Apache Junction. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 14 I)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 sixth -mile or eight hundred eighty feet (880') points along an arterial street.Additional median openings are allowed but should be the partial access type. 3)A median cut closer than eight hundred eighty feet (880') to an arterial -to -arterial intersection shall be the partial access type. 4)Median cuts less than six hundred sixty feet (660') from an arterial -to -arterial intersection are not allowed. 5)Median cuts less than six hundred sixty feet (660') from any signalized intersection or an intersection likely to be signalized are not allowed. 6)Median cuts less than eight hundred eighty feet (880') from a freeway interchange generally are not permitted, although each case will be evaluated based on the configuration of the particular interchange. City of Apache Junction Chapter 3 Street Design and Construction Engineering Design Guidelines November 2006 15 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.

City of Apache Junction Chapter 4 Stormwater Management Engineering Design Guidelines November 2006 26 b)Buoyancy calculations for the public utilities, whether existing or proposed, are required when the pipe diameter is larger than sixteen inches (16"). 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 a.In commercial and industrial areas retention may be accomplished upon paved areas (e.g. impervious surfaces such as asphalt, concrete, etc.)See Section 4.10.E. 3.Underground Storage a.Underground storage utilizes storage tanks, vaults, pipes, etc...to place the required stormwater retention volume underground on the development site.Underground storage is allowed for commercial retail and industrial type projects only.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. 5)Drainage of the structure within the required thirty- six (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. City of Apache Junction Chapter 4 Stormwater Management Engineering Design Guidelines November 2006 27 c.See Section 4.10.L 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 4.10.B.2. a & 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 right-of-ways within the project. b.Freeboard 1)There shall be a minimum of one -foot (1') 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, etc. 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). City of Apache Junction Chapter 4 Stormwater Management Engineering Design Guidelines November 2006 28 A = drainage area, including one-half (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 one-half (1/2) of all abutting streets (square feet) Drywell volumes shall not be included in the proposed storage capacities. 3.Location Retention/detention basins shall be located such that they can intercept the flows from the entire site. 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 of Apache Junction Ordinance and the approved City of Apache Junction Chapter 4 Stormwater Management Engineering Design Guidelines November 2006 29 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 I.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 three (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 one hundred year high water level. c.While it is the City's intent that the "average" depth not exceed three feet, it is also the City's intent that the basins be contoured to present an aesthetically pleasing appearance.Therefore, up to 25% of the bottom area may be up to four (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 one half (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. City of Apache Junction Chapter 4 Stormwater Management Engineering Design Guidelines November 2006 30 2)Side slopes adjacent to walls, fences, hedges, etc. (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, etc. 3.Grading/Landscaping/Joint Use as Parks a.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. 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 ofjoint 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 the following concepts will be used as the basis of reviewing the plans: 1)Curvilinear sides should be used in lieu of long stretches of straight lines. 2)Side slopes should be varied (e.g. start with 6:1 then change to 7-8:1 or more.With appropriate use of landscaping, side slopes can even be reduced to 4:1. 3)Bottom areas should contour to varying depths in lieu of uniform depth/slope. c.The tops and bottoms of side slopes shall be rounded off— generally over a distance of five (5) feet each way of the "PI". d.Landscaping — All landscaping within City right-of-way, easements or dedicated tracts shall be approved by the City Parks and Recreation Department. City of Apache Junction Chapter 4 Stormwater Management Engineering Design Guidelines November 2006 31 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 six inches within the parking area, nor shall it exceed 0.15 feet at the midpoint of any parking space. e.Interference with pedestrian traffic will be minimized in the design of the storage facility. f.A continuous fire access lane shall be provided throughout the development, and it shall be free of ponded water from the retention areas. g.All parking spaces shall be accessible during periods when the basins are filled to capacity, without pedestrians having to cross ponded water deeper than 0.15 feet. 3.Before final plan approval, an approved Drainage Report must show the calculated stormwater storage volume based on runoff from the 100 -year, 2 -hour storm, or the pre -approved 10 -year, 24- hour storm for the Downtown area and in -fill projects North of Baseline Avenue. City of Apache Junction Chapter 4 Stormwater Management Engineering Design Guidelines November 2006 32 F.OVERFLOW/OUTFALL 1.Outfall 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. 3.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. Offsite 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 right- of-ways 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 four (4) horizontal feet from any building or public roadway. 4.Retention/detention facilities shall not be located within twenty (20) feet of an active septic system nor within one hundred (100) feet of an active water well.
