The purpose of a Residential Historic Preservation District is to encourage the preservation of historic structures/districts in the City of Clayton and to assure that owners of properties in historic districts are given the opportunity to preserve specific properties/areas. The goals are as follows:
- To allow national historic districts to voluntarily preserve all contributing structures within the residential section of the designated neighborhood
- To provide a mechanism to identify and preserve the distinctive historic characteristics of the City of Clayton which represents elements of the City's cultural, social, economic, political and architectural history
- To foster civic pride in the beauty and noble accomplishments of the past as represented in the City's landmarks and historic districts
- To promote the use of landmarks and historic districts for the education, pleasure and welfare of the people of the City
All residential areas, except areas within Urban Design Districts, that are listed on the National Register of Historic Places are eligible for local designation. Designation of an area is voluntary based upon the criteria listed below:
A National Register Historic District will be considered by the Plan Commission for local designation if a petition containing signatures of owners of no less than 51% of the residential properties in an area designated as a National Historic District is received requesting local designation. The Plan Commission will hold a public information session. After the public information session, a ballot will be sent to the owner of each property in the proposed district to vote on the designation. Only the owner of property is eligible to vote. Each property will be given 1 vote. An affirmative vote of 66% of the properties in the proposed district must be received within 45 days to continue the process. If the requisite affirmative votes are received within 45 days from the mailing date, notice of the proposed designation and a public hearing to be conducted by the Plan Commission will be sent by First Class Mail to all owners within the proposed district as shown by St. Louis County records.
EXCEPTION: Current and future areas designated as Urban Design Districts (UDDs) are excluded from consideration, even if located in a National Register Historic District. These Urban Design District Standards are already special zoning areas with standards specific to each district that are not intended to preclude new development, but rather to encourage quality development whose size, scale, mass and architectural design respects the character of the district and surrounding area. These areas have and will continue to experience redevelopment that has been accommodated by the UDD Standards.
