STORMWATER MANAGEMENT AND FLOOD PROTECTION
All facilities and methods discussed in this section shall meet current APWA and building code requirements.
(1)
Applicability. The provisions of this chapter apply to all land disturbance construction activities including residential (single-family and multifamily), commercial and industrial development. Stormwater detention facilities shall be constructed and in operation prior to any construction of impervious surface and so noted on the engineering drawings.
(2)
Developer responsibility. There are many methods and/or combination of methods, which may be utilized to provide the amount of storage required. It is the responsibility of the developer to choose which method or combination of methods he or she will use. All required improvements must be designed and built according to the latest edition of the Kansas City Metropolitan APWA unless otherwise required by the City of Belton. Whenever these two are in conflict, the more restrictive applies.
(3)
Methods of storage. The following is a list of various methods of detention including conditions and limitations, which shall be observed in the selection of a method of detention.
a.
Rooftop storage.
1.
Building codes require roof load designs for rain and snow. The design load may be converted to an equivalent water depth in inches, which can be safely contained on flat roofs.
2.
The maximum storage allowed for design purposes should not exceed this depth unless a building is designed to withstand a greater roof-load. The depth of water can be controlled by proper sizing of downspouts and by constructing scuppers through the parapet walls.
3.
Overflow drains should be used to protect against possible roof overloading. Roof-water tightness is required to prevent leakage from water accumulation.
b.
Parking lots.
1.
Considerable area in commercial areas is occupied by parking lots. Planned correctly these paved areas can provide adequate detention with minimum inconvenience to the public and without functional interference. This method involves storage of runoff in depressions constructed near drains.
2.
In parking lots, detention is permitted to a maximum depth of seven inches. The maximum limits of ponding may not be designed closer than ten feet from a building unless waterproofing of the building and pedestrian accessibility are properly documented.
When detention is used on parking lots by means of retaining walls or curbs, these retaining walls and curbs shall be constructed with reinforced concrete and constructed according to APWA standards.
c.
Recreation areas.
1.
Recreation areas, such as open space or sports fields, generally have a substantial area of grass cover which can have high infiltration rates. A secondary use of such recreation areas can be made by providing for limited detention storage of runoff from adjacent areas. Because these areas are not used during periods of precipitation, detention ponding should not impede their primary use.
2.
To minimize the effects of detention, the recreation area should be designed so that it will thoroughly drain. Additionally, the vegetation used on the area should be tolerant of periodic inundation and wetness. The developer and the parks and recreation department should work closely to provide open space that can also be used for limited detention storage.
d.
Dry reservoirs. Dry reservoirs shall be designed in accordance with the latest revision of the Standard Specifications of the Kansas City Metropolitan Chapter of the American Public Works Association as modified below:
1.
Earth bottoms. All dry detention facilities shall be constructed with earth bottoms unless there is not sufficient runoff to support a plant community as determined by the director of public works. The pond bottom shall be designed as a wetland and plantings shall be installed in accordance with wetland design criteria as specified in the latest revision of the Mid-America Regional Council and American Public Works Association "Manual for Best Management Practices for Stormwater Quality."
2.
Maintenance.
(i)
Stormwater facilities shall be maintained by the owner or other responsible party as outlined in a maintenance agreement approved by the city council at the time of final plat approval.
(ii)
Disposal of waste from maintenance of facilities shall be constructed in accordance with applicable federal, state and local laws and regulations.
(iii)
Records of installation and maintenance and repair shall be retained by the owner or other responsible party for the current five-year period and shall be made available to the city public works department upon request.
(iv)
Any failure to maintain a stormwater facility in accordance with city requirements or to correct problems with a stormwater facility as required by the city after receipt of due notice shall be handled under the procedure for nuisances as outlined in the Belton City Code.
3.
Inspection.
(i)
Stormwater systems shall be inspected by the city public works department during and after construction and annually thereafter to assure consistency with the approved stormwater management plan.
(ii)
All stormwater systems shall be subject to the authority of the on-site detention inspection program of the city public works department to ensure compliance with this Code and may be inspected when deemed necessary.
(iii)
Routine or area inspections shall be based upon such reasonable selection processes as may be deemed necessary to carry out the objectives of this chapter, including but not limited to, random sampling and/or sampling in areas with evidence of stormwater pollution, illicit discharges, or similar factors. Refer to Chapter 11, Article V of the city's Code of Ordinances for details on illicit discharges and the enforcement of the prohibition of illicit discharges.
e.
Permanent lakes. Permanent lakes must be constructed according to the Kansas City Metro APWA standards and specifications.
f.
Underground storage.
1.
Stormwater runoff may be controlled by a holding tank or large size pipe. This method should be limited to areas where surface ponding is prohibited due to lack or high cost of available land or areas where the surface topography is not conducive to above-ground storage.
2.
These systems must be designed so that the water surface from the 25-year storm does not exceed the elevation of the top of the storage pipe or vault or come within six inches of the bottom of any inlet grate or exceed the top of any upstream pipe; and provision must be made to safely control the 100-year storm.
3.
Underground storage systems must be designed to be relatively maintenance free by using adequate trash screens at all inlets to the system and at the control structures avoiding the use of moving parts and avoiding the use of small control pipes and narrow weir openings.
4.
Privately maintained underground storage systems located on private property must be constructed of materials which have a similar expected life as that of the project. Tanks, vaults or oversized pipes and multiple parallel pipes may be used in these private systems.
5.
All underground storage systems must have a reasonable number and type of access locations to allow easy inspection and maintenance.
(4)
Payment in lieu of detention. Properties located within the Markey Regional Detention Watershed (defined as that property set out on Exhibit A) in lieu of providing for on-site detention in conjunction with improvements to the property, as required by section 32-1(1) of the UDC, may make a payment in lieu of storm water detention to the city (the "payment") and utilize the city's regional detention facility as shown on Exhibit A, (the regional detention facility). In order to be authorized to make a payment and utilize the regional detention facility the following must take place:
a.
For development of property being platted. An application (the "application") on forms provided by the public works department must be submitted at least 30 days prior to the planning commission's consideration of a preliminary plat which seeks to use the regional detention facility in lieu of providing for on-site detention.
b.
For development of property not being platted. If the proposed improvements to the property do not require a plat nor modifications to an existing plat, the application must be provided with the site plan submitted for development review.
c.
A drainage study (the "drainage study") must be filed with the application and contain all of the information regarding the development proposed for the property being platted and it's storm water detention needs. The drainage study shall be based on APWA 5600 and City of Belton's standards as set out in section 36-69(b) of the UDC. The drainage study shall also include: a) an analysis of the proposed and existing runoff conditions of the site; b) an analysis of the capacity of downstream storm sewers, proposed storm sewer improvements and detention/retention ponds; c) a review of drainage areas that are adjacent to or that flow through the property being platted; and d) any and all other information reasonably request by the city (the "study").
The director of public works or his designee shall have the sole discretion to approve of the study and shall include such decision for approval to the city council as part of its consideration of the agreement (the "agreement") as described below.
d.
The details of the payment shall be set out in the agreement between the city and the applicant and shall be expeditiously approved by the city council:
1.
In the case of a development requiring a plat, the agreement shall be approved by the city council in conjunction with the approval of the preliminary plat.
2.
In the case of a development which does not require a plat, the agreement shall be approved by a resolution or motion of the city council.
e.
In all regards, the payment shall be calculated at a rate (the "rate") of $5,900.00 per impervious acre of development as set out in the approved study. The payment for the property being developed shall be made to the city before a building permit will be issued for the development. After March 1, 2015 the rate shall be increased every March 1st using an escalator fact based upon the Consumer Price Index for Construction.
(5)
Dams, retention basins and siltation control. Where dams are proposed in any subdivision, they must be designed by a professional engineer registered in the state. A preliminary engineering report including soil investigations and design procedures must be submitted to the director of public works for review. When a dam is planned on private property, the engineer must certify that the dam is constructed according to the approved plans and specifications.
(6)
Stream buffer protection.
a.
Applicability. This section applies to all land or new development within the stream corridor, as defined by this section and applied to designated stream segments identified on the Belton Stream Order Map and incorporated as a part of this section. No development shall occur on a parcel of land that is within or partially within the defined stream corridor, except in accordance with this section. This section does not apply to land or to development which:
1.
Is on land covered by an approved, unexpired final plat, preliminary plat, memorandum of understanding (MOU) or preliminary plan, where such approval was given prior to the effective date of the ordinance from which this section is derived;
2.
Is covered by an unexpired building permit issued prior to the effective date of this section, in accordance with the City Code, and platting was not required prior to issuance of a building permit;
3.
Is being used for agricultural operations; or
4.
If a development obtains a Federal Clean Water Act Individual 404 Permit allowing a stream to be relocated or otherwise altered, this section will apply to the new stream location and order. A copy of the approved 404 Permit shall be submitted with the buffer plan.
(i)
No development shall be approved that proposes development on any parcel of land wholly or partially within the defined stream corridor unless the proposed development is in compliance with the applicable provisions of this section.
(ii)
Except as otherwise provided by this section, the director of public works shall administer, implement and enforce the provisions of this section. The director may delegate any powers or duties granted by this Code to other city personnel or authorized representatives.

Any action or inaction which violates the provisions of this chapter or the requirements of an approved plan may be subject to the enforcement actions outlined in this section. Any such action or inaction which is continuous with respect to time is deemed to be a public nuisance and may be abated by injunctive or other equitable relief. The imposition of any of the penalties described in the following subsections shall not prevent such equitable relief.
(1)
Notice of violation. If the city determines that an applicant or other responsible person has failed to comply with the terms and conditions of a permit, an approved site plan or the provisions of this chapter, it shall issue a written notice of violation to such applicant or other responsible person. Where a person is engaged in activity covered by this chapter without having first secured the appropriate approvals therefore, the notice of violation shall be served on the owner or the responsible person in charge of the activity being conducted on the site. The notice of violation shall contain:
a.
The name and address of the owner or the applicant or the responsible person;
b.
The address or other description of the site upon which the violation is occurring;

(2)
Penalties. In the event the remedial measures described in the notice of violation have not been completed by the date set forth for such completion in the notice of violation, anyone or more of the following actions or penalties may be taken or assessed against the person to whom the notice of violation was directed. Before taking any of the following actions or imposing any of the following penalties, the director of public works shall first notify the applicant or other responsible person in writing of its intended action, and shall provide a reasonable opportunity, of not less than ten days (except that in the event the violation constitutes an immediate danger to public health or public safety, 24 hours' notice shall be sufficient) to cure such violation. In the event the applicant or other responsible person fails to cure such violation after such notice and cure period, the director of public works may take anyone or more of the following actions or impose anyone or more of the following penalties.
(3)
Stop work order. The director of public works may issue a stop work order which shall be served on the applicant or other responsible person. The stop work order shall remain in effect until the applicant or other responsible person has taken the remedial measures set forth in the notice of violation or has otherwise cured the violation or violations described therein, provided the stop work order may be withdrawn or modified to enable the applicant or other responsible person to take necessary remedial measures to cure such violation or violations.
(4)
Withhold certificate of occupancy. The city may refuse to issue a certificate of occupancy for the building or other improvements constructed or being constructed on the site until the applicant or other responsible person has taken the remedial measures set forth in the notice of violation or has otherwise cured the violations described therein.
(5)
Suspension, revocation or modification of permit. The director of public works may suspend, revoke or modify the permit authorizing the land development project. A suspended, revoked or modified permit may be reinstated after the applicant or other responsible person has taken the remedial measures set forth in the notice of violation or has otherwise cured the violations described therein, provided such permit may be reinstated (upon such conditions as the director of public works may deem necessary) to enable the applicant or other responsible person to take the necessary remedial measures to cure such violations.
(6)
Civil penalties. In the event the applicant or other responsible person fails to take the remedial measures set forth in the notice of violation or otherwise fails to cure the violations described therein within ten days (or such greater period as the director of public works shall deem appropriate) (except that in the event the violation constitutes an immediate danger to public health or public safety, 24 hours' notice shall be sufficient) after the director of public works has taken one or more of the actions described above, the director of public works may impose a penalty not to exceed $1,000.00 (depending on the severity of the violation) for each day the violation remains unremedied after receipt of the notice of violation.
(7)
Criminal penalties. For intentional and flagrant violations of this chapter, the director of public works may issue a citation to the applicant or other responsible person, requiring such person to appear in (appropriate municipal, magistrate or recorders) court to answer charges for such violation. Upon conviction, such person shall be punished by a fine not to exceed $1,000.00 or imprisonment for 60 days or both. Each act of violation and each day upon which any violation shall occur shall constitute a separate offense.

(2)
In its review of all applications, the city will utilize the U.S. Fish and Wildlife Inventory Map to determine if further study is necessary by an applicant to determine if a wetland is located on property to be developed or upon property included in a land disturbance permit application.
(UDC 2010, § 21.5)
(a)
Introductory provisions.
(1)
Statutory authorization. The Legislature of the State of Missouri has in RSMo. 79.010 et seq., delegated the responsibility to local governmental units, to adopt floodplain management regulations designed to protect the health, safety, and general welfare.
(2)
Findings of fact.
a.
Flood losses resulting from periodic inundation. The special flood hazard areas of the city are subject to inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base; all of which adversely affect the public health, safety and general welfare. The following provisions are subject to change based on the most recent FEMA and SEMA guidelines and regulations.
b.
General causes of the flood losses. These flood losses are caused by:
1.
The cumulative effect of development in any delineated floodplain causing increases in flood heights and velocities; and
2.
The occupancy of flood hazard areas by uses vulnerable to floods, hazardous to others, inadequately elevated, or otherwise unprotected from flood damages.
(3)
Purpose. It is the purpose of this chapter to:
a.
Promote the public health, safety, and general welfare;
b.
To minimize losses;
c.
To establish or maintain the community's eligibility for participation in the National Flood Insurance Program (NFIP) as defined in 44 Code of Federal Regulations (CFR) 59.22(a)(3); and
d.
To meet the requirements of 44 CFR 60.3(d) by applying the provisions of this chapter to:
1.
Restrict or prohibit uses that are dangerous to health, safety or property in times of flooding or cause undue increases in flood heights or velocities;
2.
Require uses vulnerable to floods, including public facilities that serve such uses, be provided with flood protection at the time of initial construction; and
3.
Protect individuals from buying lands that are unsuited for the intended development purposes due to the flood hazard.
(b)
Methods used to analyze flood hazards. The flood insurance study (FIS) that is the basis of this chapter uses a standard engineering method of analyzing flood hazards which consist of a series of interrelated steps.
(1)
Selection of a base flood that is based upon engineering calculations which permit a consideration of flood factors such as its expected frequency of occurrence, the area inundated and the depth of inundation. The base flood selected for this chapter is representative of large floods which are characteristic of what can be expected to occur on the particular streams subject to this chapter. It is in the general order of a flood which could be expected to have a one percent chance of occurrence in any one year as delineated on the Federal Insurance Administrator's Flood Insurance Study and illustrative materials for Cass County, Missouri dated January 2, 2013, as amended, and any future revisions thereto.
(2)
Calculation of water surface profiles is based on a standard hydraulic engineering analysis of the capacity of the stream channel and overbank areas to convey the regulatory flood.
(3)
Computation of a floodway required to convey this flood without increasing flood heights more than one foot at any point.
(4)
Delineation of floodway encroachment lines within which no development is permitted that would cause any increase in flood height.
(5)
Delineation of flood fringe, i.e., the area outside the floodway encroachment lines that is still subject to inundation by the base flood.
(6)
All methods used to calculate water surface profiles, floodway boundaries and fringes shall conform to the latest FEMA and SEMA guidelines.
(c)
Applicability. This chapter applies to all lands within the jurisdiction of the City of Belton, Missouri identified as numbered and unnumbered A zones and AE zones, on the Flood Insurance Rate Maps (FIRMs) for Cass County on map panel numbers 29037C0004F, 29037C0009F, 29037C0010F, 29037C0012F, 29037C0016F, 29037C0017F, 29037C0028F, and 29037C0036F, dated January 2, 2013 as amended, and any future revisions thereto.
(d)
Compliance. No development located within the special flood hazard areas of this community may be located, extended, converted or structurally altered without full compliance with the terms of this chapter and other applicable regulations.
(e)
Abrogation and greater restrictions. It is not intended by this chapter to repeal, abrogate or impair any existing easements, covenants or deed restrictions. However, where this chapter imposes greater restrictions, the provisions of this chapter prevail. All other ordinances inconsistent with this chapter are hereby repealed to the extent of the inconsistency only.
(f)
Interpretation. In their interpretation and application, the provisions of this chapter will be held to be requirements, will be liberally construed in favor of the governing body, and will not be deemed a limitation or repeal of any other powers granted by state statutes.
(g)
Warning and disclaimer of liability. The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on engineering and scientific methods of study. Larger floods may occur on rare occasions or the flood heights may be increased by manmade or natural causes. This chapter does not imply that areas outside the floodway and flood fringe or land uses permitted within such areas will be free from flooding or flood damage. This chapter does not create a liability on the part of the City of Belton or any officer or employee thereof, for any flood damages that may result from reliance on this chapter or any administrative decision lawfully made under this chapter.
(h)
Severability. If any section, clause, provision, or portion of this article is adjudged unconstitutional or invalid by a court of appropriate jurisdiction, the remainder of this article shall not be affected thereby.

(UDC 2010, § 21.7; Ord. No. 2012-3880, § 3, 12-18-2012)
Editor's note— *A recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick-disconnect type utilities and security devices, and has no permanently attached additions.
Located within areas of special flood hazard are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters that carry debris and potential projectiles, the following provisions apply:
(1)
The community shall select and adopt a regulatory floodway based on the principle that the area chosen for the regulatory floodway must be designated to carry the waters of the base flood without increasing the water surface elevation of that flood more than one foot at any point;
(2)
The community shall prohibit any encroachments, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge;
(3)
If requirements are satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this chapter; and
(4)
In unnumbered A zones, the community shall obtain, review and reasonably utilize any base flood elevation or floodway data currently available from federal, state or other sources.
(UDC 2010, § 21.8)
(a)
Additional buffer requirements. All land development activity subject to this chapter shall meet the following requirements:
(1)
A buffer plan approved by the director of public works is required for all projects where development or redevelopment is to occur on property that includes or is adjacent to a FEMA designated floodplain or land subject to flooding during a 100-year storm event. The plan shall set forth an informative, conceptual, and schematic representation of the proposed activity so as to enable the city an opportunity to make a reasonably informed decision regarding the proposed activity.
(2)
The delineation of the buffer and its component zones shall be shown on any building construction plans, preliminary plat and final plat, as may be required by this Code.

(b)
The required width for all stream buffers shall be a minimum average of 40 feet on each side of the stream beginning at the stream centerline.
(c)
In no case shall the buffer be less than the floodplain limits as shown on the flood insurance rate map (FIRM) and flood boundary and floodway map (FBFM) Cass County Panels dated January 2, 2013 as amended, and any future revisions thereto.
(d)
If stream buffers, or stream channels, are disturbed or destroyed during development activities, they shall be restored using native vegetation or plantings as outlined in required "Planting Palette."
(e)
The following structures, practices, and activities are permitted in the stream buffer, with specific design or maintenance features, subject to the review and approval of the city:
(1)
Activities for the purpose of building one of the following:
a.
A stream crossing by a driveway, transportation route or utility line;

(UDC 2010, § 21.10; Ord. No. 2012-3880, § 3, 12-18-2012)
STORMWATER MANAGEMENT AND FLOOD PROTECTION
All facilities and methods discussed in this section shall meet current APWA and building code requirements.
(1)
Applicability. The provisions of this chapter apply to all land disturbance construction activities including residential (single-family and multifamily), commercial and industrial development. Stormwater detention facilities shall be constructed and in operation prior to any construction of impervious surface and so noted on the engineering drawings.
(2)
Developer responsibility. There are many methods and/or combination of methods, which may be utilized to provide the amount of storage required. It is the responsibility of the developer to choose which method or combination of methods he or she will use. All required improvements must be designed and built according to the latest edition of the Kansas City Metropolitan APWA unless otherwise required by the City of Belton. Whenever these two are in conflict, the more restrictive applies.
(3)
Methods of storage. The following is a list of various methods of detention including conditions and limitations, which shall be observed in the selection of a method of detention.
a.
Rooftop storage.
1.
Building codes require roof load designs for rain and snow. The design load may be converted to an equivalent water depth in inches, which can be safely contained on flat roofs.
2.
The maximum storage allowed for design purposes should not exceed this depth unless a building is designed to withstand a greater roof-load. The depth of water can be controlled by proper sizing of downspouts and by constructing scuppers through the parapet walls.
3.
Overflow drains should be used to protect against possible roof overloading. Roof-water tightness is required to prevent leakage from water accumulation.
b.
Parking lots.
1.
Considerable area in commercial areas is occupied by parking lots. Planned correctly these paved areas can provide adequate detention with minimum inconvenience to the public and without functional interference. This method involves storage of runoff in depressions constructed near drains.
2.
In parking lots, detention is permitted to a maximum depth of seven inches. The maximum limits of ponding may not be designed closer than ten feet from a building unless waterproofing of the building and pedestrian accessibility are properly documented.
When detention is used on parking lots by means of retaining walls or curbs, these retaining walls and curbs shall be constructed with reinforced concrete and constructed according to APWA standards.
c.
Recreation areas.
1.
Recreation areas, such as open space or sports fields, generally have a substantial area of grass cover which can have high infiltration rates. A secondary use of such recreation areas can be made by providing for limited detention storage of runoff from adjacent areas. Because these areas are not used during periods of precipitation, detention ponding should not impede their primary use.
2.
To minimize the effects of detention, the recreation area should be designed so that it will thoroughly drain. Additionally, the vegetation used on the area should be tolerant of periodic inundation and wetness. The developer and the parks and recreation department should work closely to provide open space that can also be used for limited detention storage.
d.
Dry reservoirs. Dry reservoirs shall be designed in accordance with the latest revision of the Standard Specifications of the Kansas City Metropolitan Chapter of the American Public Works Association as modified below:
1.
Earth bottoms. All dry detention facilities shall be constructed with earth bottoms unless there is not sufficient runoff to support a plant community as determined by the director of public works. The pond bottom shall be designed as a wetland and plantings shall be installed in accordance with wetland design criteria as specified in the latest revision of the Mid-America Regional Council and American Public Works Association "Manual for Best Management Practices for Stormwater Quality."
2.
Maintenance.
(i)
Stormwater facilities shall be maintained by the owner or other responsible party as outlined in a maintenance agreement approved by the city council at the time of final plat approval.
(ii)
Disposal of waste from maintenance of facilities shall be constructed in accordance with applicable federal, state and local laws and regulations.
(iii)
Records of installation and maintenance and repair shall be retained by the owner or other responsible party for the current five-year period and shall be made available to the city public works department upon request.
(iv)
Any failure to maintain a stormwater facility in accordance with city requirements or to correct problems with a stormwater facility as required by the city after receipt of due notice shall be handled under the procedure for nuisances as outlined in the Belton City Code.
3.
Inspection.
(i)
Stormwater systems shall be inspected by the city public works department during and after construction and annually thereafter to assure consistency with the approved stormwater management plan.
(ii)
All stormwater systems shall be subject to the authority of the on-site detention inspection program of the city public works department to ensure compliance with this Code and may be inspected when deemed necessary.
(iii)
Routine or area inspections shall be based upon such reasonable selection processes as may be deemed necessary to carry out the objectives of this chapter, including but not limited to, random sampling and/or sampling in areas with evidence of stormwater pollution, illicit discharges, or similar factors. Refer to Chapter 11, Article V of the city's Code of Ordinances for details on illicit discharges and the enforcement of the prohibition of illicit discharges.
e.
Permanent lakes. Permanent lakes must be constructed according to the Kansas City Metro APWA standards and specifications.
f.
Underground storage.
1.
Stormwater runoff may be controlled by a holding tank or large size pipe. This method should be limited to areas where surface ponding is prohibited due to lack or high cost of available land or areas where the surface topography is not conducive to above-ground storage.
2.
These systems must be designed so that the water surface from the 25-year storm does not exceed the elevation of the top of the storage pipe or vault or come within six inches of the bottom of any inlet grate or exceed the top of any upstream pipe; and provision must be made to safely control the 100-year storm.
3.
Underground storage systems must be designed to be relatively maintenance free by using adequate trash screens at all inlets to the system and at the control structures avoiding the use of moving parts and avoiding the use of small control pipes and narrow weir openings.
4.
Privately maintained underground storage systems located on private property must be constructed of materials which have a similar expected life as that of the project. Tanks, vaults or oversized pipes and multiple parallel pipes may be used in these private systems.
5.
All underground storage systems must have a reasonable number and type of access locations to allow easy inspection and maintenance.
(4)
Payment in lieu of detention. Properties located within the Markey Regional Detention Watershed (defined as that property set out on Exhibit A) in lieu of providing for on-site detention in conjunction with improvements to the property, as required by section 32-1(1) of the UDC, may make a payment in lieu of storm water detention to the city (the "payment") and utilize the city's regional detention facility as shown on Exhibit A, (the regional detention facility). In order to be authorized to make a payment and utilize the regional detention facility the following must take place:
a.
For development of property being platted. An application (the "application") on forms provided by the public works department must be submitted at least 30 days prior to the planning commission's consideration of a preliminary plat which seeks to use the regional detention facility in lieu of providing for on-site detention.
b.
For development of property not being platted. If the proposed improvements to the property do not require a plat nor modifications to an existing plat, the application must be provided with the site plan submitted for development review.
c.
A drainage study (the "drainage study") must be filed with the application and contain all of the information regarding the development proposed for the property being platted and it's storm water detention needs. The drainage study shall be based on APWA 5600 and City of Belton's standards as set out in section 36-69(b) of the UDC. The drainage study shall also include: a) an analysis of the proposed and existing runoff conditions of the site; b) an analysis of the capacity of downstream storm sewers, proposed storm sewer improvements and detention/retention ponds; c) a review of drainage areas that are adjacent to or that flow through the property being platted; and d) any and all other information reasonably request by the city (the "study").
The director of public works or his designee shall have the sole discretion to approve of the study and shall include such decision for approval to the city council as part of its consideration of the agreement (the "agreement") as described below.
d.
The details of the payment shall be set out in the agreement between the city and the applicant and shall be expeditiously approved by the city council:
1.
In the case of a development requiring a plat, the agreement shall be approved by the city council in conjunction with the approval of the preliminary plat.
2.
In the case of a development which does not require a plat, the agreement shall be approved by a resolution or motion of the city council.
e.
In all regards, the payment shall be calculated at a rate (the "rate") of $5,900.00 per impervious acre of development as set out in the approved study. The payment for the property being developed shall be made to the city before a building permit will be issued for the development. After March 1, 2015 the rate shall be increased every March 1st using an escalator fact based upon the Consumer Price Index for Construction.
(5)
Dams, retention basins and siltation control. Where dams are proposed in any subdivision, they must be designed by a professional engineer registered in the state. A preliminary engineering report including soil investigations and design procedures must be submitted to the director of public works for review. When a dam is planned on private property, the engineer must certify that the dam is constructed according to the approved plans and specifications.
(6)
Stream buffer protection.
a.
Applicability. This section applies to all land or new development within the stream corridor, as defined by this section and applied to designated stream segments identified on the Belton Stream Order Map and incorporated as a part of this section. No development shall occur on a parcel of land that is within or partially within the defined stream corridor, except in accordance with this section. This section does not apply to land or to development which:

(UDC 2010, § 21.5)
(a)
Introductory provisions.
(1)
Statutory authorization. The Legislature of the State of Missouri has in RSMo. 79.010 et seq., delegated the responsibility to local governmental units, to adopt floodplain management regulations designed to protect the health, safety, and general welfare.
(2)
Findings of fact.
a.
Flood losses resulting from periodic inundation. The special flood hazard areas of the city are subject to inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base; all of which adversely affect the public health, safety and general welfare. The following provisions are subject to change based on the most recent FEMA and SEMA guidelines and regulations.
b.
General causes of the flood losses. These flood losses are caused by:
1.
The cumulative effect of development in any delineated floodplain causing increases in flood heights and velocities; and
2.
The occupancy of flood hazard areas by uses vulnerable to floods, hazardous to others, inadequately elevated, or otherwise unprotected from flood damages.
(3)
Purpose. It is the purpose of this chapter to:
a.
Promote the public health, safety, and general welfare;
b.
To minimize losses;
c.
To establish or maintain the community's eligibility for participation in the National Flood Insurance Program (NFIP) as defined in 44 Code of Federal Regulations (CFR) 59.22(a)(3); and
d.
To meet the requirements of 44 CFR 60.3(d) by applying the provisions of this chapter to:
1.
Restrict or prohibit uses that are dangerous to health, safety or property in times of flooding or cause undue increases in flood heights or velocities;
2.
Require uses vulnerable to floods, including public facilities that serve such uses, be provided with flood protection at the time of initial construction; and
3.
Protect individuals from buying lands that are unsuited for the intended development purposes due to the flood hazard.
(b)
Methods used to analyze flood hazards. The flood insurance study (FIS) that is the basis of this chapter uses a standard engineering method of analyzing flood hazards which consist of a series of interrelated steps.
(1)
Selection of a base flood that is based upon engineering calculations which permit a consideration of flood factors such as its expected frequency of occurrence, the area inundated and the depth of inundation. The base flood selected for this chapter is representative of large floods which are characteristic of what can be expected to occur on the particular streams subject to this chapter. It is in the general order of a flood which could be expected to have a one percent chance of occurrence in any one year as delineated on the Federal Insurance Administrator's Flood Insurance Study and illustrative materials for Cass County, Missouri dated January 2, 2013, as amended, and any future revisions thereto.
(2)
Calculation of water surface profiles is based on a standard hydraulic engineering analysis of the capacity of the stream channel and overbank areas to convey the regulatory flood.
(3)
Computation of a floodway required to convey this flood without increasing flood heights more than one foot at any point.
(4)
Delineation of floodway encroachment lines within which no development is permitted that would cause any increase in flood height.
(5)
Delineation of flood fringe, i.e., the area outside the floodway encroachment lines that is still subject to inundation by the base flood.
(6)
All methods used to calculate water surface profiles, floodway boundaries and fringes shall conform to the latest FEMA and SEMA guidelines.
(c)
Applicability. This chapter applies to all lands within the jurisdiction of the City of Belton, Missouri identified as numbered and unnumbered A zones and AE zones, on the Flood Insurance Rate Maps (FIRMs) for Cass County on map panel numbers 29037C0004F, 29037C0009F, 29037C0010F, 29037C0012F, 29037C0016F, 29037C0017F, 29037C0028F, and 29037C0036F, dated January 2, 2013 as amended, and any future revisions thereto.
(d)
Compliance. No development located within the special flood hazard areas of this community may be located, extended, converted or structurally altered without full compliance with the terms of this chapter and other applicable regulations.
(e)
Abrogation and greater restrictions. It is not intended by this chapter to repeal, abrogate or impair any existing easements, covenants or deed restrictions. However, where this chapter imposes greater restrictions, the provisions of this chapter prevail. All other ordinances inconsistent with this chapter are hereby repealed to the extent of the inconsistency only.
(f)
Interpretation. In their interpretation and application, the provisions of this chapter will be held to be requirements, will be liberally construed in favor of the governing body, and will not be deemed a limitation or repeal of any other powers granted by state statutes.
(g)
Warning and disclaimer of liability. The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on engineering and scientific methods of study. Larger floods may occur on rare occasions or the flood heights may be increased by manmade or natural causes. This chapter does not imply that areas outside the floodway and flood fringe or land uses permitted within such areas will be free from flooding or flood damage. This chapter does not create a liability on the part of the City of Belton or any officer or employee thereof, for any flood damages that may result from reliance on this chapter or any administrative decision lawfully made under this chapter.
(h)
Severability. If any section, clause, provision, or portion of this article is adjudged unconstitutional or invalid by a court of appropriate jurisdiction, the remainder of this article shall not be affected thereby.

(UDC 2010, § 21.7; Ord. No. 2012-3880, § 3, 12-18-2012)
Editor's note— *A recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick-disconnect type utilities and security devices, and has no permanently attached additions.
Located within areas of special flood hazard are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters that carry debris and potential projectiles, the following provisions apply:
(1)
The community shall select and adopt a regulatory floodway based on the principle that the area chosen for the regulatory floodway must be designated to carry the waters of the base flood without increasing the water surface elevation of that flood more than one foot at any point;
(2)
The community shall prohibit any encroachments, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge;
(3)
If requirements are satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this chapter; and
(4)
In unnumbered A zones, the community shall obtain, review and reasonably utilize any base flood elevation or floodway data currently available from federal, state or other sources.
(UDC 2010, § 21.8)
