[Ord. No. 2025-09, 1-27-2025]
A. 
Intent. It is the intent of these stormwater provisions to ensure to the greatest extent possible that the stormwater that is generated on a property is retained on that property or transferred from the property to an MSD stormwater system in a controlled manner.
These provisions are intended to control stormwater resulting from a design storm event [15-year, 20-minute] or less intensive storm event. It is recognized that there will be times when a storm event will exceed the design storm event (whether that be from flash flooding, a more intensive storm event, or ground saturation) and will not be entirely controlled.
These provisions are intended to control the stormwater resulting from the property at issue, NOT to control stormwater that flows from other properties onto or through the property at issue.
B. 
Applicability. These provisions shall apply to any driveway greater than twenty (20) feet in width or in any instance where a residential property owner wants to exceed the allowable lot coverage calculation for their property; provided, however, a variance from the lot coverage requirements must be sought by the Board of Adjustment prior to any consideration by the City Council of any additional impervious surface allowances described herein.
C. 
Administration And Enforcement. The administrative and enforcement provisions as outlined below, as amended from time to time, shall be the administrative and enforcement provisions to be used when administering and enforcing this Article.

a. 
Any new detached one- or two-family dwelling.
b. 
Any installation of additional impervious surface on a one- or two-family residential property where the new impervious or semi-pervious surface results in more than the allowable lot coverage maximum as limited by the zoning district.
The requirement of sealed plans from a registered design professional shall not be required in the following instances:
(1) 
Where it can be demonstrated that one hundred percent (100%) of the differential stormwater resulting from the new impervious surfaces shall be directed to an MSD stormwater system that is contiguous with the lot at issue.
(2) 
Where the inspector can determine based upon the site visit required in Section 500.250(F) that differential stormwater resulting from the proposed construction or grading can be totally dissipated within the confines of the development parcel of land without adversely impacting adjacent properties or rights-of-way.
(3) 
Any installation of a retention or detention area including but not limited to rain gardens and dry or wet holding areas.
(4) 
Receptacles including but not limited to pre-engineered rain barrels and cisterns.
Any stormwater control drawings and/or calculations that are required to be sealed shall be sealed by a registered design professional who, by Missouri State law, is permitted to seal such drawings and/or calculations. (see Chapter 327, RSMo.)
G. 
Site Visit. The responsible party shall schedule an inspection of the lot before the issuance of a building permit to determine that the plan submitted will adequately address stormwater control and to allow the inspector an opportunity to have full knowledge of the property before the work commences.
H. 
Ongoing Stormwater Management. The responsible party shall be responsible for controlling all stormwater generated on the property.
I. 
Regulations. Unless otherwise approved by the Director of Community Development or his/her designee in writing, the following principles shall be applied when controlling stormwater:
1. 
If any existing impervious surface is removed during construction or development, that area shall be considered as pervious for the purpose of calculating the differential resulting from the new construction.
Example 1: Replacing a one hundred (100) square foot concrete patio with a two hundred (200) square foot home addition, the stormwater differential to be addressed would be based on the full two hundred (200) square feet of new impervious roof surface.
Example 2: When constructing a new residence on a lot where a house was demolished, the lot will be treated as if it had been entirely undeveloped, thereby requiring one hundred percent (100%) or the stormwater to be addressed in the plan.
Example 3: Adding a second story to an existing building would require a stormwater plan to address the stormwater form the entire roof over the addition.
EXCEPTION: If the new construction results in the impervious surface being replaced with a pervious or semi-pervious surface, the development shall be credited with a net reduction in stormwater run-off for that area of the development.
2. 
The calculation of differential stormwater resulting from the new construction shall assume that the area covered by new impervious materials is replacing pervious areas, regardless of the preconstruction status of the site. Semi-pervious and pervious surfaces replacing impervious surfaces shall be credited as a reduction in stormwater. [Example: A one hundred (100) square foot concrete patio (one hundred percent (100%) impervious surface) that is removed to install a two hundred (200) square foot building addition: the differential is based on two hundred (200) square feet of one hundred percent (100%) impervious surface replacing two hundred (200) square feet of pervious surface.]
3. 
The calculation of differential stormwater resulting from the new construction shall assume that the area covered by new impervious materials is replacing pervious areas, regardless of the preconstruction status of the site. Semi-pervious and pervious surfaces replacing impervious surfaces shall be credited as a reduction in stormwater. [Example: A two hundred (200) square foot concrete patio (one hundred percent (100%) impervious surface) that is removed to install a two hundred (200) square foot building addition: the differential is based on two hundred (200) square feet of one hundred percent (100%) impervious surface replacing two hundred (200) square feet of pervious surface.]
4. 
All stormwaters shall be conveyed to an approved location by an approved means including but not limited to adequately sized pipes, channels, cisterns, and retention/detention areas. Where possible, sheet drainage should be used in lieu of point drainage.
5. 
No stormwater shall be discharged to an adjoining public or private property in a manner that negatively impacts the adjoining property. Existing conditions shall be the basis for determining negative impact.
6. 
Stormwater shall be directed away from buildings and structures on the lot of issue as well as adjoining lots.
7. 
No point discharge outlet shall be located and directed in the vicinity of any property line if the stormwater discharge from a Design Storm Event can reasonably be expected to flow above ground onto an adjacent property or rights-of-way, unless the owner of the impacted property (or the Director of Community Development or his/her designee, in the case of public rights-of-way) has specifically granted a stormwater easement to the owner of the property which is the source of the stormwater. Point discharge outlets include but are not limited to downspout outlets, sump pump outlets, and yard pop ups.
EXCEPTION: An exception can be granted by the Director of Community Development or his/her designee in the case of public rights-of-way, when an applicant can demonstrate a hardship. When the Director of Community Development or his/her designee determines that no other option exists and the intent of these provisions is met, the outlet may be allowed within ten (10) feet of the property line. The request shall be in writing and addressed to the Director of Community Development or his/her designee, who shall respond to the request within thirty (30) days of the receipt of the request. No response by the Director of Community Development or his/her designee within thirty (30) days shall be the same as granting the request.
The Director of Municipal Operations may permit a curb cut to permit stormwater to discharge directly to the curb/gutter portion of the street. The curb cut shall be permitted only in cases of necessity not merely for the convenience of the applicant.
8. 
No stormwater shall discharge into a sanitary system, except when approved by St. Louis Metropolitan Sewer District (MSD) or when discharging into an approved combination sewer.
9. 
Designing for maximum infiltration and on-site detention of stormwater utilizing rain gardens, cisterns, rain barrels, and similar receiving areas and devices is encouraged.
10. 
All pavement and constructed surfaces shall be considered as one hundred percent (100%) impervious for purposes of calculating differential stormwater.
EXCEPTION:
a. 
Surfaces may be considered as semi-pervious if it can be demonstrated that the surface is designed to allow for a certain percentage of imperviousness and retention.
b. 
Plans sealed by a registered professional may provide a design that allows for varying percentages of imperviousness.
c. 
Surfaces including but not limited to lawn and garden areas may be considered as five percent (5%) impervious.
11. 
Calculations for stormwater control shall be based on a Design Storm Event as defined in Section 500.250(D).
12. 
When controlling differential stormwater, the designer shall not exceed preconstruction conditions including but not limited to volume, velocity, and location of storrnwater discharge.
13. 
Stormwater control structures and systems designed and installed as part of an approved stormwater plan, including but not limited to rain gardens, cisterns, retention areas and detention areas shall be properly maintained at all times.
14. 
Stormwater control structures, including but not limited to ram barrels and cisterns shall be drained to ensure, to the greatest extent possible, that the required holding capacity is available for a designed storm event.
15. 
Stormwater control structures may be inspected periodically to ensure that they are being properly maintained.
