No. 07-26 §1, 12-27-07) SECTION 420.030: APPLICABILITY This Chapter shall apply to all land development activity on property containing a stream protection area as defined in Section 420.020 of this Chapter. These requirements are in addition to and do not replace or supersede any other applicable buffer or floodplain requirements established under State 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. 1. Grandfather provisions. This Chapter shall not apply to the following activities: a. 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 Chapter. b. 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. c. 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 Chapter. 560 § 420.030 Stream Buffer Protection Regulations § 420.030 d. 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 Chapter. 2. Exemptions. The following specific activities are exempt from this Chapter. Exemption of these activities does not constitute an exemption for any other activity proposed do a property. a. Activities for the purpose of building one (1) of the following: (1) A stream crossing by a driveway, transportation route or utility line; (2) Public water supply intake or public wastewater structures or stormwater outfalls; (3) Intrusions necessary to provide access to a property; (4) Public access facilities that must be on the water including boat ramps, docks, foot trails leading directly to the river, fishing platforms and overlooks; (5) Unpaved foot trails and paths; (6) 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. b. Public sewer 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 Section 420.030(2) above. c. Land development activities within a right-of-way existing at the time this Chapter takes effect or approved under the terms of this Chapter. d. Within an easement of any utility existing at the time this Chapter takes effect or approved under the terms of this Chapter, 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. e. 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 Building Department 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 Building Department to be reasonably necessary to correct any impairment such emergency work may have caused to the water conveyance capability, stability or water quality of the protection area. f. 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 561 § 420.030 Riverview Village Code § 420.040 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. g. 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 Chapter, it shall apply to new subdividing 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 under Section 420.040 below. (Ord. No. 07-26 §1, 12-27-07) SECTION 420.040: LAND DEVELOPMENT REQUIREMENTS A. Buffer And Setback Requirements. All land development activity subject to this Chapter 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 Chapter, 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. 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. C. All land disturbance activities shall be carried out in such a manner as to minimize inconvenience and harm to adjacent properties and property owners. 1. Where a parcel was platted prior to the effective date of this Chapter, and its shape, topography or other physical condition prevents land development consistent with this Chapter, and the review of the Building Department finds and determines that the requirements of this Chapter prohibit the otherwise lawful use of the property by the owner, the Board of Adjustment of the Village of Riverview 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 Board of Adjustment of the Village of Riverview shall grant no variance from any provision of this Chapter without first conducting a public hearing on the application for a variance and authorizing the granting of the variance by an affirmative vote of the Board of Adjustment. The Village of Riverview shall give public notice of each such 562 § 420.040 Stream Buffer Protection Regulations § 420.040 public hearing in a newspaper of general circulation within the Village of Riverview. The Village of Riverview 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. Variances will be considered only in the following cases: a. When a property's shape, topography or other physical conditions existing at the time of the adoption of this Chapter prevents land development unless a buffer variance is granted. b. Unusual circumstances when strict adherence to the minimal buffer requirements in the Chapter would create an extreme hardship. Variances will not be considered when, following adoption of this Chapter, 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. 4. The following factors will be considered in determining whether to issue a variance: a. The shape, size, topography, slope, soils, vegetation and other physical characteristics of the property; b. The locations of all streams on the property, including along property boundaries; c. The location and extent of the proposed buffer or setback intrusion; 563 § 420.040 Riverview Village Code § 420.060 d. Whether alternative designs are possible which require less intrusion or no intrusion; e. The long-term and construction water quality impacts of the proposed variance; and f. Whether issuance of the variance is at least as protective of natural resources and the environment. (Ord. No. 07-26 §1, 12-27-07) SECTION 420.050: COMPATIBILITY WITH OTHER REGULATIONS AND REQUIREMENTS This Chapter 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 Chapter should be considered minimum requirements, and where any provision of this Chapter imposes restrictions different from those imposed by another 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. 07-26 §1, 12-27-07) SECTION 420.060: ADDITIONAL INFORMATION REQUIREMENTS FOR DEVELOPMENT ON BUFFER ZONE PROPERTIES Any permit applications for property requiring buffers and setbacks hereunder must include the following: 1. A site plan showing: a. The location of all streams on the property; b. Limits of required stream buffers and setbacks on the property; c. Buffer zone topography with contour lines at no greater than five (5) foot contour intervals; d. Delineation of forested and open areas in the buffer zone; and e. Detailed plans of all proposed land development in the buffer and of all proposed impervious cover within the setback. 2. A description of all proposed land development within the buffer and setback; and 3. Any other documentation that the Building Department may reasonably deem necessary for review of the application and to insure that the buffer zone ordinance is addressed in the approval process. All buffer and setback areas must be recorded on the final plat of the property following plan approval. A note to reference the vegetative buffer shall state: "There shall be no clearing, grading, construction or disturbance of vegetation except as permitted by Stream Buffer Protection Ordinance 07-26 (Chapter 420)." (Ord. No. 07-26 §1, 12-27-07) 564 § 420.070 Stream Buffer Protection Regulations § 420.090 SECTION 420.070: RESPONSIBILITY Neither the issuance of a development permit nor compliance with the conditions thereof nor with the provisions of this Chapter shall relieve any person from any responsibility otherwise imposed by law for damage to persons or property; nor shall the issuance of any permit hereunder serve to impose any liability upon the Village of Riverview, its officers or employees for injury or damage to persons or property. (Ord. No. 07-26 §1, 12-27-07) SECTION 420.080: INSPECTION A. The Building Department may cause inspections of the work in the buffer and setback to be made periodically during the course thereof and shall make a final inspection following completion of the work. The permittee shall assist the Building Department in making such inspections. The Building Department shall have the authority to conduct such investigations as it may reasonably deem necessary to carry out its duties as prescribed in this Chapter and for this purpose to enter at reasonable time upon any property, public or private, for the purpose of investigating and inspecting the sites of any land development activities within the protection area. B. No person shall refuse entry or access to any authorized representative or agent who requests entry for purposes of inspection, and who presents appropriate credentials, nor shall any person obstruct, hamper or interfere with any such representative while in the process of carrying out official duties.
