It is not the intent of this ordinance to repeal, abrogate or impair any existing easement, covenant or deed restriction. Where these provisions conflict or overlap, whichever imposes the more stringent restrictions shall prevail. 51.09.030 Amendments For the purpose of providing for the health, safety and general welfare of the community, the City Council may from time to time amend the provisions imposed by these subdivision regulations in the manner prescribed by law. 51.09.040 Variances The Planning Commission may reduce or otherwise vary the requirements of these regulations whenever it encounters the situation described below. In granting such variances, the Planning Commission may require whatever conditions it feels are necessary to secure the basic objectives of the particular regulations. Any variance granted by the Planning Commission shall be noted in its official minutes. A. Hardship. Where the Planning Commission finds that extraordinary hardships or particular difficulties may result from strict compliance with these regulations, they may, after written application by the developer, grant variances to the regulations subject to specified conditions so that substantial justice may be done and the public interest secured. Such variances shall not have the effect of nullifying the intent and purpose of these regulations or the Comprehensive Plan. The Planning Commission shall not grant variances to these regulations unless they make findings based upon evidence presented to them in each specific case that: 1. Because of unusual surroundings, shape or topographical conditions of the specific property, a particular hardship to the owner would result, as S:\ord\subdivision ord.doc 20 distinguished from a mere inconvenience, if the strict letter of the regulations were adhered to. 2. The conditions upon which the request for a variance is based are unique to the property and are not applicable, generally, to other property and have not been created by any person having an interest in the property. 3. The purpose of the variance is not based exclusively upon a desire for financial gain. 4. The granting of the variance will not be detrimental to the public's health, safety or welfare or injurious to property or improvements in the neighborhood in which the property is located. B. Large Scale Residential Developments. The standards and requirements of these regulations may be modified by the planning commission in the case of a plan for a new residential neighborhood which, in the judgment of the planning commission, complies with the objectives of the Comprehensive Plan and Section 50.60.000 of the Zoning Ordinance. C. Design Innovations. From time to time subdivisions may be designed to provide unusual amenities and at the same time fail to conform strictly to the provisions of these regulations. The Planning Commission may waive certain requirements of these regulations in approving subdivisions involving detailed and workable design innovations that would yield an enhanced living environment for future occupants. 51.09.050 Assurance Agreements No plat or plats of any subdivision shall be approved unless the improvements required by this ordinance have been installed prior to such approval or unless the developer shall have signed an assurance agreement to establish the responsibility for the construction of such improvements in a satisfactory manner as specified by the City Engineer and Brookings Municipal Utilities Department. This assurance agreement shall be recorded with the Register of Deeds at the time of the filing of the plat. 51.10.000 ENFORCEMENT A.
