Development Code Chapter 5 Shoreland & Wetland Mangement RegulationsOrdinance No. 198 Page 1 of 29 CITY OF SCANDIA ORDINANCE NO. 198 AN ORDINANCE AMENDING CHAPTER 5 OF THE SCANDIA DEVELOPMENT CODE, SHORELAND MANAGEMENT REGULATIONS The City Council of the City of Scandia, Washington County, Minnesota hereby ordains: Section 1. Amendment. Chapter 5 of the Development Code of the City of Scandia shall be repealed and replaced with the new Chapter 5, Shoreland Management Regulations, as follows: SECTION 1. STATUTORY AUTHORIZATION AND PURPOSE 1.1 Statutory Authorization. This shoreland ordinance is adopted pursuant to the authorization and policies contained in Minnesota Statutes, Chapter 103F, Minnesota Regulations, Parts 6120.2500 - 6120.3900, and the planning and zoning enabling legislation in Minnesota Statutes Chapter 462. 1.2 Intent and Purpose. The Legislature of Minnesota has delegated responsibility to local governments of the state to regulate the subdivision, use, and development of the shorelands of public waters and thus preserve and enhance the quality of surface waters, conserve the economic and natural environmental values of shorelands, and provide for the wise use of waters and related land resources. This responsibility is hereby recognized by the City of Scandia. The City finds that the uncontrolled use of shorelands of the City affects the public health, safety, and general welfare by contributing to pollution of public waters and potentially decreasing property, public, and natural resource values. It is the intent and purpose of these regulations to: (1) Designate suitable land use districts of each public water body. (2) Regulate the placement of sanitary and waste treatment facilities on lots. (3) Regulate the area of a lot and the length of water frontage suitable for building sites. (4) Regulate the alteration of shorelands of public waters. (5) Regulate alterations of the natural vegetation and the natural topography along shorelands. (6) Conserve natural resources and maintain a high standard of environmental quality. (7) Preserve and enhance the quality of surface waters. (8) Preserve the economic, natural, and environmental values of shorelands. (9) Provide for the utilization of water and related land resources. (10) Maintain water quality, reduce flooding and erosion, and provide sources of food and habitat for a variety of fish and wildlife. Ordinance No. 198 Page 2 of 29 2.0 GENERAL PROVISIONS AND DEFINITIONS 2.1 Jurisdiction. The provisions of this ordinance shall apply to the shorelands of Public Water bodies as defined by Minnesota Statutes, Section 103G.005, Subd. 15 and 15a, and as classified in Section 4.1 of this ordinance. The requirements of Section 6.41B of this ordinance shall apply to all wetlands in the City that are regulated by the Minnesota Wetland Conservation Act and as defined in Minnesota Rules 8420.0111. A body of water created by a private user where there was no previous shoreland may, at the discretion of the governing body, be exempt from this ordinance. 2.2 Enforcement. The City of Scandia is responsible for the administration and enforcement of this ordinance. Any violation of the provisions of this ordinance or failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with grants of variances or conditional uses) constitutes a misdemeanor and is punishable as defined by law. Violations of this ordinance can occur regardless of whether or not a permit is required for a regulated activity listed in Section 3.2 of this ordinance. 2.3 Severability. If any section, clause, provision, or portion of this ordinance is adjudged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this ordinance shall not be affected thereby. 2.4 Abrogation and Greater Restrictions.

Where these controls do not exist, the elevation to which the lowest floor, including basement, is placed or flood-proofed must be determined as follows: Ordinance No. 198 Page 20 of 29 A. For lakes, by placing the lowest floor at a level at least three feet (3’) above the highest known water level, or three feet above the ordinary high water level, whichever is higher; B. For rivers and streams, by placing the lowest floor at least three feet (3’)above the highest known flood elevation.

Under all three approaches, technical evaluations must be done by a qualified engineer or hydrologist consistent with Minnesota Rules, parts 6120.5000 to 6120.6200 governing the management of flood plain areas. If more than one approach is used, the highest flood protection elevation determined must be used for placing structures and other facilities; and C.

Determine Base Density: A. For residential PUDs, divide the suitable area within each tier by the minimum single residential lot area for lakes to determine the allowable number of dwelling units, or base density, for each tier. For rivers, if a minimum lot area is not specified, divide the tier width by the minimum single residential lot width. B. Allowable densities may be transferred from any tier to any other tier further from the waterbody, but must not be transferred to any tier closer to the waterbody. C. All PUDs with densities at or below the base density must meet the design standards in Section 10.6 10.54 Step 4. Determine if the Site can Accommodate Increased Density . A.
