A. 
The following criteria are to be applied in the design and development of stormwater drainage facilities:
1. 
Stormwater collection systems.
a. 
Design frequency. Ten (10) year frequency rainfall amounts from technical papers published by the U.S. Weather Bureau shall be used to determine the discharges for the design of storm sewers, inlet capacities and such appurtenances.
b. 
Hydrologic design. Hydrologic designs and summary runoff computations shall be prepared by a professional engineer registered in the State of Missouri and must be made using the Rational Method (with "C" factors based upon percent of impervious site area from the tabulation in this paragraph), Soil Conservation Service Technical Release 55 (TR-55) or other technical method acceptable to the City. If other methods than the two (2) noted herein are proposed, then approval must be obtained from the City.

c. 
Hydraulic design. Hydraulic computations for pipes and ditches shall use open-channel, pressurized pipe, culvert, orifice and weir equations and coefficients generally accepted by the civil engineering community. The project engineer shall clearly document the sources used for hydraulic design.
d. 
Conveyance on streets. The 10-year storm flow shall be allowed to be conveyed on all streets to a depth of two (2) inches above the roadway centerline, but in no case shall the stormwater extend either to more than fourteen (14) feet beyond the edge of pavement or back of curb or outside the street right-of-way.
e. 
Maintenance during construction.
(1) 
Straw bale barriers, silt fences or similar erosion control features must be provided during construction to control the transport of silt from the site and into the public streets or storm water system.
(2) 
Seeding and mulching or sodding of earthen improvements must made as soon as possible after completion of the improvements.
(3) 
Prior to acceptance by the City all features must be free of sediment and a sufficient stand of grass or other protective measures must be established to retard erosion and control the transport of sediment.
(4) 
If the developer fails to provide adequate maintenance and the facilities become inoperative or ineffective, the City of Sikeston may perform remedial work at the developer's expense.
2. 
Stormwater detention or retention facilities.
a. 
When required. Detention or retention systems will be required for development sites from which the post-development 10-year discharge would exceed the 10-year pre-development discharge and where the existing downstream drainage facilities have inadequate capacity to accept the additional post-development discharge from the site. Design computations will be required to demonstrate that no detention is required. Developments without detention or retention must be individually approved by the City Manager or his/her designee.
b. 
Detention design frequency. Detention basins shall be designed to receive the 10-year post-development discharge and limit the maximum discharge from the site to the 2-year pre-development discharge. Computations must be provided for the basin volume and for the performance of the control structure.
c. 
Detention volume for sites of 20 acres or less. For sites of twenty (20) acres or less the volumes for detention basins shall be determined by either a routing of the 10-year hydrograph through the basin and control structure by an acceptable computer-based hydraulic routing program or by providing a volume equivalent to provided one thousand eight hundred (1,800) seconds of storage of the difference between the 10-year peak post-development discharge and the 2-year peak pre-development discharge.
d. 
Detention volume for sites of over 20 acres. For sites of over twenty (20) acres the volumes for detention basins must be determined by routing the 10-year hydrograph through the basin and control structure with an acceptable computer-based hydraulic routing program.
e. 
Retention basin design. Storm water retention basins or hybrid detention/retention basins may be used to take advantage of soil infiltration to reduce the peak rate of discharge. Discharge from such basins shall not exceed the 2-year pre-development flow. Design seepage rates shall not be more than ten percent (10%) of that observed by on-site percolation tests or indicated by soil report data. The total volume of no-discharge retention-only basins shall not be less than that required to contain the total volume of runoff from an eight and one-half (8.5) inch rainfall event as indicated by Table 2-1 of TR-55.
f. 
Forms of detention and retention. Detention and retention basins may be provided in the following forms:
(1) 
Drain-dry earthen basins with maximum 4:1 side slopes, concrete lined low-flow channels and a one (1) foot minimum freeboard,
(2) 
Permanent ponds with maximum 4:1 side slopes, minimum permanent water depth of three (3) feet and two (2) foot minimum freeboard,
(3) 
Underground piping and basins with provisions for silt control and removal,
(4) 
Parking lots to a maximum depth of twelve (12) inches.
(5) 
The above list of design options is not intended to preclude the use of innovative design concepts.
g. 
Detention and retention facility design and site details. The design and site details for detention and retention basins must provide for the following:
(1) 
Adequate space and legal authority for access (a minimum of fifteen (15) feet around top of slopes) must be provided for maintenance and inspection.
(2) 
The facilities must be designed and have emergency spillways to allow passage of a 100-year developed runoff without detriment to the structure and must limit backwater to avoid damage to the improvements on the site.
(3) 
Low-flow openings of less than twelve (12) inches in diameter or minor dimension shall be provided with a two (2) inch bar screen with a net opening area of at least one hundred forty-four (144) square inches.
h. 
Maintenance during construction.
(1) 
Detention or retention facilities must be constructed before other major site disruption to allow the features to be used for the control of the transport sediment.
(2) 
Accumulated sediment must be removed whenever the presence of such sediment degrades the performance of the structure in the control of transport of sediment.
(3) 
If the developer fails to provide adequate maintenance and the facilities become inoperative or ineffective or become a nuisance, the City of Sikeston may perform remedial work at the developer's expense.
