C. 
Final Stormwater Management Plan.
1. 
Following the review of the preliminary stormwater management plan and after the general approval of the preliminary plan by the Village, a final stormwater management plan shall be prepared for each phase of the proposed project as each phase is developed. The submittal of the final plan shall coincide with application for final approval of the development and shall constitute a refinement of the concepts approved in the preliminary plan. It is important to note that if a project is to be phased, the total area of the conceptual project is to be considered in all calculations and that facilities should be designed for each phase which would be compatible with those of the total development plan. The final stormwater management plan shall specifically enumerate the private property responsible for the maintenance of the stormwater control facilities and all appurtenances, including architectural screenings and plantings, and shall include all maps, calculations necessary for the approval of the plan by the Village.
2. 
The final stormwater management plan shall be reviewed by the Village. If it is determined that the proposed development will provide control of stormwater runoff in accordance with the purposes, design criteria and performance standards of this chapter and will not be detrimental to the public health, safety, and general welfare, the Village shall approve the plan or conditionally approve the plan, setting forth in writing, the conditions thereof. If approved, a drainage permit for the development shall be granted.

If it is determined that the proposed development will not control stormwater runoff in accordance with this chapter, the Village shall disapprove the stormwater management plan and the application and data shall be returned to the applicant for corrective action and resubmittal.
[Ord. No. 481, 5-13-2013]
A. 
Unless otherwise approved, the following rules shall govern the design of improvements with respect to managing stormwater runoff:
1. 
In determining the amount of stormwater runoff from a development it is important for the designer to relate the methodology to be used in his calculations to the proportionate size of the tributary watershed area. In developments of twenty-five (25) acres or less, the Rational Method of calculating the quantity of runoff shall be used. Optionally, in developments of twenty-five (25) acres or less, those persons not wishing to calculate the quantity of water to be retained may use the attached tabular form.[1] Developments where the area developed is greater than twenty-five (25) acres and up to two hundred (200) acres shall be designed using the Unit Hydrograph Method. The preferred method of hydrograph development shall be as described in the Soil Conservation Service publication "Urban Hydrology For Small Watersheds" (Technical Release No. 55 - June 1986). Use of methods other than those described shall be upon the approval of the Village.
[1]
Editor's Note: This table is included as an attachment to this chapter.
2. 
Development design. Streets, blocks, depth of lots, parks, and other public grounds shall be located and laid out in such a manner as to minimize the velocity of overland flow and allow maximum opportunity for infiltration of stormwater into the ground, and to preserve and utilize existing and planned streams, channels and detention basins, and include, whenever possible, streams and floodplains within parks and other public grounds.
3. 
Enclosed systems and open channels. The design criteria for storm drainage facilities, shall be submitted to and approved by the Village.
4. 
Methods of controlling downstream flooding. The Village shall determine whether the proposed plan will cause or increase downstream local flooding conditions. This determination shall be made on the basis of existing downstream development and drainage system capabilities and an analysis of stormwater runoff prior to and after the proposed development. If the Village determines that the proposed development will cause or increase downstream local flooding conditions during the design storm, provisions to minimize such flooding conditions shall be included in the design of storm drainage improvements and/or the temporary controlled detention of stormwater runoff and its regulated discharge to the downstream storm drainage system.
5. 
Downstream improvements. Improvements to minimize downstream flooding conditions may include, but not be limited to, the construction of dams, dikes, levees, and floodwalls; culvert enlargement; and channel clearance and modification projects.
6. 
Detention basins. Temporary detention of stormwater runoff may be used in developments in order to minimize downstream flooding conditions. Temporary storage facilities will not be required in situations where the installation of such a facility would adversely affect the environment or where the site discharges directly into a major stream or system component. The design of temporary detention facilities shall be in accordance with the following design criteria:
a. 
Storage volume requirements.
(1) 
Sufficient storage volume shall be provided to prevent local flooding damage. Such volume shall be adequate to contain the differential volume of runoff which would result from the design storm occurring on a fully developed site minus the volume of runoff which would result from the design storm occurring over an undeveloped site. Inflow rates into the storage basin shall be determined utilizing either the Rational Method or the Unit Hydrograph Method dependent on the development size limitations and methodologies described in Subsection (A)(1) of this Section. The minimum rainfall event to be utilized in determining the detention storage volume shall be based on the twenty-five-year rainfall event.
(2) 
When utilizing the SCS method of hydrograph development (Technical Release No. 55), the minimum rainfall events shall be based upon the twenty-four-hour point rainfall as indicated in Technical Paper No. 40, published by the Department of Commerce, Weather Bureau.
(3) 
In the event of special circumstances, the Village may require the use of storms of greater magnitude. When utilizing the Rational Method for runoff computations, the rainfall intensity (I) and runoff coefficient (C) shall be based upon the area being fully developed in accordance with the planned land usage.
(4) 
Associated with the analysis will be the routing of the storm hydrograph through the basin to determine the effect of the temporary storage on the rate of inflow. As a result of the flood routing procedure, a determination of the required combination to temporary storage volume and outlet controls required to reduce post-development peak outflows to no more than the rate may be made.
b. 
Maximum allowable release rate.
(1) 
The basic design factor used in the determination of the maximum release rate of a detention facility shall be the capability of the downstream system to handle the flow adequately. In general, the maximum release rate shall be defined as the predevelopment runoff resulting from a ten-year return frequency rainfall calculated using the Rational Formula:
Q = CIA
Where:
Q
=
Peak rate of runoff, in cubic feet per second.
C
=
Weighted runoff coefficient (average of the coefficient assigned to the different types of contributing areas).
I
=
Average rainfall intensity, in inches per hour, for the selected frequency and for duration equal to the time of concentration.
A
=
Drainage area, in acres, of the subject property, tributary to point under design.
(2) 
Deviations from the use of this rainfall frequency in design calculations shall be only where approved by the Village. Actual rainfall intensity (I) shall be determined for the time of concentration of the tributary area in its undeveloped and natural state. The runoff coefficient (C) shall likewise be determined for the land in its undeveloped state. In no case shall the release rate exceed the existing safe storm drainage capacity of the downstream system or watercourse.
c. 
Freeboard. The minimum elevation of the top of the detention storage basin embankment shall be at least one (1) foot above the water surface with the emergency spillway flowing at design, or a minimum of two (2) feet above the crest of the emergency spillway.
d. 
Sediment storage. A sediment storage volume of at least five percent (5%) of the total required temporary storage volume for runoff detention shall be provided.
e. 
Outlet control works. Outlet works shall not include any mechanical components or devices and shall function without requiring attendance or control during operation. Size and hydraulic characteristics shall be such that all water in detention storage is released to the downstream storm sewer system within twenty-four (24) hours after the end of the design rainfall.
f. 
Emergency overflow. A method of emergency overflow shall be designed and provided to permit the safe passage of runoff generated in excess of a one-hundred-year storm.
g. 
Other design considerations. All stormwater detention basins shall be designed with the capability of passing a one-hundred-year hydrograph from a fully developed watershed basin through the outlet works without causing a failure of the embankment. It is not the intent of this requirement to entail any additional reduction of the integrity and safety of the structure.
h. 
Design data submittal. In addition to complete plans, the following design data shall be submitted for all temporary detention facilities:
(1) 
Rainfall hydrograph plotted in units of inches per hour as ordinates, and time from beginning of the storm as abscissas.
(2) 
Runoff hydrograph plotted in units of cubic feet per second runoff rate of the tributary area as ordinates, and time from the start of runoff as abscissas.
(3) 
Area - capacity curve for proposed detention facility plotted in units of datum elevation as ordinates, and cumulative volume of storage as abscissas.
(4) 
Discharge characteristics curve or outlet works plotted in units of detention facility water surface elevation as ordinates, and discharge rate for cubic feet per second (cfs) as abscissas.
(5) 
Storage capacity-Inflow and outflow curves in units of accumulated volume as ordinates, and time from the start of runoff as abscissas. Curves shall be so arranged that the vertical distance between the accumulated storage and accumulated discharge will indicate the net volume in storage at any point in time. Curves shall be extended to the time required for complete discharge of all runoff stored in the detention facility.
7. 
Other detention methods.
a. 
In addition to the above criteria, the following detention methods may be utilized to provide temporary detention storage:
(1) 
Wet bottom basins. The minimum normal depth of water before the introduction of excess stormwater shall be four (4) feet. If fish are to be used to keep the basin clean, at least one-fourth (1/4) of the area of the permanent pool must have a minimum depth of ten (10) feet. For emptying purposes, cleaning or shoreline maintenance, facilities shall be provided or plans prepared for the use of auxiliary equipment to permit emptying and drainage. All surface area within the fluctuating limits of the basin storage or that which is susceptible to or designed as overflow areas from storms with a higher return frequency than those utilized in the design of the facility shall be seeded and mulched, sodded or paved.
(2) 
Dry bottom basins. Where possible, these shall be designed to serve secondary purposes for recreation, open space or other types of use which will not be adversely affected by occasional or intermittent flooding. To facilitate interior drainage, pave with concrete. Architectural screenings and/or plantings are required for this type of facility unless specifically excluded by Council action.
(3) 
Rooftop storage. Detention storage may be met in total or in part by detention on roofs. Details of such designs, which shall be included in the drainage permit applications, shall include the depth and volume of storage, details of outlet devices and downdrains, elevations of overflow scuppers, design loadings for the roof structure and emergency overflow provisions.
(4) 
Paved parking lots. May be designed to provide temporary storage of stormwater on all or a portion of their surfaces to a maximum depth of nine (9) inches. Outlets will be designed so as to empty the stored waters in such a time as to create the least amount of inconvenience to the public. Minimum slopes of one percent (1%) and maximum slopes of four percent (4%) are to be utilized.
b. 
The minimum freeboard from the maximum water ponding elevation to lowest sill elevation of adjacent buildings or structures shall be one (1) foot.
[Ord. No. 481, 5-13-2013]
A. 
Stormwater Channel Location. Generally acceptable locations of stormwater runoff channels in the design of a subdivision may include but not be limited to the following:
1. 
In a depressed median of a double roadway, street, or parkway, provided that the median is wide enough to permit maximum three to one (3:1) side slopes.
2. 
Centered on back lot lines or entirely within the rear yards of a single row of lots or parcels.
3. 
In each of the foregoing cases, a drainage easement to facilitate maintenance and design flow shall be provided and shown on the plat. No structures will be allowed to be constructed within or across stormwater channels.
B. 
Storm Sewer Outfall. The storm sewer outfall shall be designed so as to provide adequate protection against downstream erosion and scouring.
C. 
Lot Lines. Whenever the plans call for the passage and/or storage of floodwater, surface runoff, or stormwater along lot lines, the grading of all such lots shall be prescribed and established for the passage and/or storage of waters. No structure may be erected in these areas which will obstruct the flow of stormwater. Additionally, installation of fences and the planting of shrubbery or trees within the areas will not be permitted. Changes in the grade and contours of the floodwater or stormwater runoff channels will not be permitted unless approved in writing by the Village.
D. 
Manholes. All sanitary sewer manholes constructed in a floodplain or in an area designed for the storage or passage of floodwater or stormwater, shall be provided with either a water-tight manhole cover or be constructed with a rim elevation of the design storm, whichever is applicable to the specific area.
E. 
Easements. Permanent easements for the detention and conveyance of stormwater, including easements of access to structures and facilities, shall be dedicated to the public.
F. 
Drainage Permits. A drainage permit for projects including detention facilities can be granted by the Building Official only after the final stormwater management plan has been approved by the Village and all covenants and easements have been dedicated, accepted, and recorded, and all required maintenance assurances and required bonds have been executed.

[Ord. No. 481, 5-13-2013]
Upon approval of the stormwater management plan by the Village, and acceptance of the applicant's assurances of performance and maintenance as provided in this chapter, the Building Official shall issue a drainage permit. The permit shall set forth the terms and conditions of the approved stormwater management plan.
[Ord. No. 481, 5-13-2013]
Those wishing to occupy a development without completing the construction in conformance with the approved final stormwater management plan shall deposit with the Building Official a performance bond, cash escrow, certified check, or other acceptable form of performance security for the full amount of the work to be done as determined by the Village. Only upon completion of the construction in conformance with the approved final stormwater management plan, shall an occupancy permit be issued.
[Ord. No. 481, 5-13-2013]
Any person aggrieved by any final decision of the Village may seek review by a court of competent jurisdiction in the manner provided by the laws of the State of Missouri.
[Ord. No. 481, 5-13-2013]
A. 
The violation of any provision of this Chapter is a misdemeanor. Any person, firm, association, partnership or corporation convicted shall be subject to a fine not to exceed five hundred dollars ($500.00); and the Village of Country Club, Missouri, shall further have the authority to maintain suits or actions in any court of competent jurisdiction for the purpose of enforcing any provisions of this thereof; and in addition to other remedies, institute injunction, mandamus, or other appropriate action or proceeding to prevent such unlawful erection, construction, reconstruction, alteration, conversion, maintenance, or use, or to correct or abate such violation, or to prevent the occupancy of the building, structure, or land. Each day any violation of this Chapter shall continue shall constitute a separate offense. Additionally, the Building Official may, upon ten (10) days' written notice, revoke the occupancy permit issued or to withhold the issuance of any building permit for any or all premises for which the facility exists, abuts or purports to support in the approved stormwater management plan or in the alternative, may order utilities disconnected. Nothing in this Section shall prevent the Director of Health and Welfare from exercising his authority in relation to nuisances.
B. 
Notwithstanding any other provision of this Chapter, whenever any property, based on the latest revision of this policy, is determined to need stormwater detention facilities which have a capacity of less than one thousand (1,000) cubic feet, the developer may pay to the Village, in lieu of constructing required stormwater detention facilities, not less than one dollar ($1.00) for each cubic foot of required detention. This money shall be used by the Village to construct drainage improvements within the drainage basin where the stormwater facilities should have been constructed. A waiver of the detention facility requirement may not be allowed if the Village has made a finding that there is a significant drainage problem below the property where the waiver is proposed even though the detention facility is marginally efficient. The Village may consider in making such determination that the discharge of any additional waters at an increased rate onto the properties below is not desirable due to significant drainage problems that exist on subservient properties. Annually in July, the payment in lieu of construction fee shall be revised by the Village to reflect the annual percentage change in construction cost by using the Construction Price Index, increase or decrease, from the previous twelve (12) months.
