Storm drains, when designed as independent structures, shall accommodate a 10- year storm. 3.The peak flows from a 100 -year storm must be carried within the cross-section between finished grade at buildings and at least 6"[15.25cm]below finished floor elevation. 4.Retention basins are permitted to a MAXIMUM of 3 feet [1m]in depth of impounded water with MAXIMUM side slopes of 4:1 and must be constructed so that storm water will dissipate within 36 hours after a storm. A 25% freeboard is recommended.Pumping, surface percolation, controlled or gravity discharge pipe, and dry wells are acceptable methods.Dry wells must be registered with ADEQ. 5.Retention areas for which the developer does not establish a private means for its perpetual maintenance acceptable to the City, must be dedicated to the City.Areas dedicated to the City must meet the design standards and requirements described in the "Parks, Open Space, and Rights -of -Way Landscape Standards" provided by the Parks Department. 6.Existing water courses should be maintained and may be required to be dedicated to the City as drainageways.Underground street crossings for these water courses shall be sized for a 10 -year flood. 7.Drainage and retention covenants must be described either on the subdivision plat or a document to be recorded with the Pinal County Recorders Office.A typical form is provided as Exhibit "B". 8.Developments south of Old West Highway need not include drainage areas upstream of Old West Highway provided existing structures are measured and a Q10 is calculated based upon the structure flowing full with a head equal to the existing highway pavement grade. 9.Apache Junction participates in the National Flood Insurance Program,Federal Emergency Management Agency (FEMA).All recognized flood plains and floodways must be delineated on the plans. Engineering Guidelines August 1995 12 PRELIMINARY DRAINAGE REPORT 1.A preliminary drainage report shall be presented with preliminary development plans. Engineering reviews may not be scheduled without this report which shall be on separate, letter -sized sheets with necessary maps and attachments.Handwritten comments on a plan sheet are not acceptable. 2.Delineate the boundaries of on -site and off -site drainage areas, together with their areas, weighted runoff coefficient, time of concentration, and intensity. 3.Indicate the drainage pattern of all existing and proposed streets and building sites. Label by number the different critical points and where inlets/outlets are to be located. 4.Each sub -area is to be analyzed for the peak flow generated by a 10 -year storm. Use of the rational method is preferred.Hydrology and hydraulics design methods should be taken out of the Maricopa County "Drainage Design Manual"Volumes I, II, M. 5.Inlets shall be designed wherever the flow exceeds the street capacity.They are to be analyzed separately and catch basin computations shall be submitted. 6.Design storm drains and submit design computations showing plan and profile on civil drawings. 7.If storm runoff flows onto the property to be developed from adjacent properties, this must be described in detail.Drainage area, calculated peak flows, and other pertinent runoff data must be presented.If the flow is in a defined channel, the channel can be improved.An 8 -foot bottom to accommodate maintenance vehicles may be required.Special consideration of the use of open channels is to be given on each individual project by the City.Channels for the runoff from areas outside the development may be realigned through the new development.Special precautions at the point of discharge for velocity, erosion and sedimentation must be evaluated. 8.Indicate the retention volume required by the formula: drainage area (S. F.) x C x .2 = retention volume in Cubic Feet.
