This Article shall be known as the "Florissant Stream Buffer Protection Ordinance."
[Ord. No. 8748, 11-22-2021]
A.
The City of Florissant finds that buffers adjacent to stream systems provide numerous environmental protection and resource management benefits which can include the following:
1.
Protection, restoring and maintaining the chemical, physical and biological integrity of streams and their water resources;
2.
Removing pollutants delivered in urban stormwater;
3.
Reducing erosion and controlling sedimentation;
4.
Protection and stabilizing stream banks;
5.
Providing for infiltration of stormwater runoff;
6.
Maintaining base flow of streams;
7.
Contributing the organic matter that is a source of food and energy for the aquatic ecosystem;
8.
Providing tree canopy to shade streams and promote desirable aquatic habitat;
9.
Providing riparian wildlife habitat;
10.
Furnishing scenic value and recreational opportunity;
11.
Providing opportunities for the protection and restoration of green space.
[Ord. No. 8748, 11-22-2021]
The purpose of this Article is to establish minimal acceptable requirements for the design of buffers to protect the streams, wetlands and floodplains of the City of Florissant; to protect the water quality of watercourses, reservoirs, lakes and other significant water resources within the City of Florissant; to protect Florissant's riparian and aquatic ecosystems; and to provide for the environmentally sound use of Florissant's land resources.
[Ord. No. 8748, 11-22-2021]
The following words, terms and phrases, when used in this Article, shall have the meanings ascribed to them in this Section, except where the context clearly indicates a different meaning:
With respect to a stream, a natural or enhanced vegetated area (established by Section 505.390 below) lying adjacent to the stream.
Any land area susceptible to flooding, which would have at least a one percent (1%) probability of flooding occurrence in any calendar year based on the basin being fully developed as shown on the current land use plan, i.e., the regulatory flood. This pertains to the 100-year floodplain only.
Any manmade paved, hardened or structural surface regardless of material. Impervious cover, includes, but is not limited to, rooftops, buildings, streets, roads, decks, swimming pools and any concrete or asphalt, unless such asphalt or concrete is designed to allow the saturation of water into the ground and is approved by the Director of Public Works as a pervious surface.
Any land change including, but not limited to, clearing, grubbing, stripping, removal of vegetation, dredging, grading, excavating, transporting and filling of land, construction, paving and any other installation of impervious cover.
Those actions or activities which comprise, facilitate or result in land development.
Any land or vegetation change, including, but not limited to, clearing, grubbing, stripping, removal of vegetation, dredging, grading, excavating, transporting and filling of land, that do not involve construction, paving or any other installation of impervious cover.
Those actions or activities which comprise, facilitate or result in land disturbance.
Any plot, lot or acreage shown as a unit on the latest County tax assessment records.
The permit issued by the Building Division required for undertaking any land development activity.
Any individual, partnership, firm, association, joint venture, public or private corporation, trust, estate, commission, board, public or private institution, utility, cooperative, City, County or other political subdivision of the State, any interstate body or any other legal entity.

Belonging or related to the bank of a river, stream, lake, pond or impoundment.
With respect to a stream, the area established by Section 505.390 extending beyond any buffer applicable to the stream.
Any stream, beginning at:
The sloping land that contains the stream channel and the normal flows of the stream. Where no established top-of-bank can be determined, the stream bank will be the "ordinary high water mark" as defined by the Corps of Engineers in Title 33 of the Code of Federal Regulation, Part 3283.3.
The portion of the watercourse that contains the base flow of the stream.
[Ord. No. 8748, 11-22-2021]
A.
This Article shall apply to all land development activity on property containing a stream protection area as defined in Section 505.370 of this Article. These requirements are in addition to, and do not replace or supersede, any other applicable buffer or floodplain requirements established under State or local law and approval or exemption from these requirements do not constitute approval or exemption from buffer requirements established under State law or from other applicable local, State or Federal regulations.
B.
Legal Non-Conforming Provisions. The following shall not apply to this Article:
1.
Work consisting of the repair or maintenance of any lawful use of land that is zoned and approved for such use on or before the effective date of this Article.
2.
Existing development and ongoing land disturbance activities, including, but not limited to, existing agriculture, silviculture, landscaping, gardening and lawn maintenance, except that new development or land disturbance activities on such properties will be subject to all applicable buffer requirements.
3.
Any land development activity that is under construction, fully approved for development, scheduled for permit approval or has been submitted for approval as of the effective date of this Article.
4.
Land development activity that has not been submitted for approval but that is part of a larger master development plan, such as for an office park or other phased development that has been previously approved within two (2) years of the effective date of this Article.
C.
Exemptions. The following specific activities are exempt from this Article. Exemption of these activities does not constitute an exemption for any other activity proposed on a property.
1.
Activities for the purpose of building one (1) of the following:
a.
A stream crossing by a driveway (bridge), transportation route or utility line;
b.
Public water supply intake or public wastewater structures or stormwater outfalls;
c.
Intrusions necessary to provide access to a property;
d.
Public access facilities that must be on the water including boat ramps, docks, foot trails, leading directly to the river, fishing platforms and overlooks;
e.
Foot trails and paths, pervious or impervious, approved only by the Director of Public Works;
f.
Activities to restore and enhance stream bank stability, vegetation, water quality and/or aquatic habitat, so long as native vegetation and bioengineering techniques are used and said work is approved by the Director of Public Works.
2.
Public Line Easements. This includes such impervious cover as is necessary for the operation and maintenance of the utility, including, but not limited to, manholes, vents and valve structures. This exemption shall not be construed as allowing the construction of roads, bike paths or other transportation routes in such easements, regardless of paving material, except for access for the uses specifically cited in Subsection (C)(1) above.
3.
Land development activities within a right-of-way existing at the time this Article takes effect or approved under the terms of this Article.
4.
Within an easement of any utility existing at the time this Article takes effect or approved under the terms of this Article, land disturbance activities and such impervious cover as is necessary for the operation and maintenance of the utility including, but not limited to, manholes, vents and valve structures.
5.
Emergency work necessary to preserve life or property. However, when emergency work is performed under this Section, the person performing it shall report such work to the Director of Public Works on the next business day after commencement of the work. Within ten (10) days thereafter, the person shall apply for a permit and perform such work within such time period as may be determined by the review and permitting authority to be reasonably necessary to correct any impairment such emergency work may have caused to the water conveyance capacity, stability or water quality of the protection area.
6.
Forestry and silviculture activities on land that is zoned for forestry, silvicultural or agricultural uses and are not incidental to other land development activity. If such activity results in land disturbance in the buffer that would otherwise be prohibited, then no other land disturbing activity other than normal forest management practices will be allowed on the entire property for three (3) years after the end of the activities that intruded on the buffer.
D.
Any activities approved under a 404 permit issued by the Corps of Engineers and 401 water quality certification issued by the Missouri Department of Natural Resources. After the effective date of this Article, the requirements herein shall apply to new subdivisions and platting activities. Any land development activity within a buffer established hereunder or any impervious cover within a setback established hereunder is prohibited unless a variance is granted pursuant to Section 505.390 of this Article.
[Ord. No. 8748, 11-22-2021]
A.
Buffer And Setback Requirements. All land development activity subject to this Article shall meet the following requirements:
1.
For streams depicted as a solid blue line on the U.S.G.S. map, an undisturbed natural vegetative buffer shall be maintained for fifty (50) feet, measured horizontally, on both banks (as applicable) of the stream as measured from the top of the stream bank. For all other streams subject to this Article, an undisturbed natural vegetative buffer shall be maintained for twenty-five (25) feet, measured horizontally, on both banks (as applicable) of the stream as measured from the top of the stream bank.
2.
An additional setback shall be maintained for twenty-five (25) feet, measured horizontally, beyond the undisturbed natural vegetative buffer, in which all impervious cover shall be prohibited, except pervious paving shall be allowed when reviewed and approved by the Director of Public Works. Grading, filling and earthmoving shall be minimized within the setback.
3.
No septic tanks or septic tank drain fields shall be permitted within the buffer or the setback.
B.
Variance Procedures. Variances from the above buffer and setback requirements may be granted in accordance with the following provisions:
1.
Where a parcel was platted prior to the effective date of this Article, and its shape, topography or other existing physical condition prevents land development consistent with this Article, and the Director of Public Works finds and determines that the requirements of this Article prohibit the otherwise lawful use of the property by the owner, the City Council may grant a variance from the buffer and setback requirements hereunder, provided such variance requires mitigation measures to offset the effects of any proposed land development on the parcel.
2.
Except as provided above, the City Council shall grant no variance from any provision of this Article without first conducting a public hearing on the application for variance and authorizing the granting of the variance by an affirmative vote of the City Council. The City of Florissant shall give public notice of each such public hearing in a newspaper of general circulation within the City of Florissant. The City of Florissant shall require that the applicant post a sign giving notice of the proposed variance and the public hearing. The sign shall be of a size and posted in such a location on the property as to be clearly visible from the primary adjacent road right-of-way.
C.
Variances will be considered only in the following cases:
1.
When a property's shape, topography or other physical conditions existing at the time of the adoption of this Article prevents land development unless a buffer variance is granted.
2.
Unusual circumstances when strict adherence to the minimal buffer requirements in this Article would create an extreme hardship. Variances will not be considered when, following adoption of this Article, actions of any property owner of a given property have created conditions of a hardship on that property.
3.
At a minimum, a variance request shall include the following information:
a.
A site map that includes locations of all streams, wetlands, floodplain boundaries and other natural features as determined by field survey;
b.
A description of the shape, size, topography, slope, soils, vegetation and other physical characteristics of the property;
c.
A detailed site plan that shows the locations of all existing and proposed structures and other impervious cover, the limits of all existing and proposed land disturbance, both inside and outside the buffer and setback. The exact area of the buffer to be affected shall be accurately and clearly indicated;
d.
Documentation of unusual hardship should the buffer be maintained;
e.
At least one (1) alternative plan, which does not include a buffer or setback intrusion, or an explanation of why such a site plan is not possible;
f.
A calculation of the total area and length of the proposed intrusion;
g.
A stormwater management site plan, if applicable; and
h.
Proposed mitigation, if any, for the intrusion. If no mitigation is proposed, the request must include an explanation of why none is being proposed.
D.
The following factors will be considered in determining whether to issue a variance:
1.
The shape, size, topography, slope, soils, vegetation and other physical characteristics of the property;
2.
The locations of all streams on the property, including along property boundaries;
3.
The location and extent of the proposed buffer or setback intrusion;
4.
Whether alternative designs are possible which require less intrusion or no intrusion;
5.
The long-term and construction water-quality impacts of the proposed variance;
6.
Whether issuance of the variance is at least as protective of natural resources and the environment.
[Ord. No. 8748, 11-22-2021]
This Article is not intended to interfere with, abrogate or annul any other ordinance, rule or regulation, Statute or other provision of law. The requirements of this Article should be considered minimum requirements and where any provision of this Article imposes restrictions different from those imposed by any other ordinance, rule, regulation or other provision of law, whichever provisions are more restrictive or impose higher protective standards for human health or the environment shall be considered to take precedence.
[Ord. No. 8748, 11-22-2021]
