Residential Designed Development Procedure. The purpose of this Section is to provide a permissive, voluntary and alternate zoning procedure in the "A", "B", "C" and "D" single-family residential and "AR" attached residential zoning districts in order to permit greater flexibility in the size and configuration of lots without altering the allowable residential density in these districts and to provide thereby for desirable and proper common open space, tree cover, recreation areas, parks or scenic vistas and the preservation of the natural beauty of the City.
1.
Variation in number, size of lots. The City Council may by ordinance grant a residential designed development permit upon recommendation of the Planning and Zoning Commission, when it finds that the residential designed development proposal is consistent with good planning practice, consistent with good site landscape planning, is not detrimental to the existing and permitted uses in the surrounding area, is deemed desirable to promote the purposes of this Section and is in accordance with the following criteria.
a.
Minimum project area. No residential designed development permit shall be granted for any area of less than four (4) acres.
b.
Gross acreage. The lot sizes within the subdivision may vary from those required by the regulations for the single-family residential zoning district within which the site is located. The maximum number of lots that may be approved shall be computed by including only common area and lot acreage in gross acreage and dividing the gross acreage by the minimum lot area requirements of the district.
c.
Yards. The minimum front yard and side yard requirements for each lot as set out in the regulations for the single-family residential zoning district within which the site is located may be reduced by the City Council and, if so reduced, shall be set out on the preliminary subdivision plan to be submitted in accordance with Chapter 410, Subdivision and Development of Land.
d.
Site and building coverages. The maximum site and building coverage requirements for each lot, as set out in the regulations for the single-family residential zoning district within which the site is located, may be increased by the City Council and, if so increased, shall be set out on the preliminary subdivision plan to be submitted in accordance with Chapter 410, Subdivision and Development of Land. In subdivisions approved prior to July 25, 1983 (adoption of Ordinance Number 1044) that are without a maximum site coverage set out on the preliminary subdivision plan, lots having less than fifty-one percent (51%) of the minimum lot area allowed by the underlying zoning district shall be subjected to the following site coverage percentage: for an A-RDD lot, thirty percent (30%); for a B-RDD lot, thirty-seven and five tenths (37.5%).
[Ord. No. 5418 §1, 2-9-2015]
2.
Common areas. As part of the residential designed development plan, common land for open space of recreational use shall be reserved for common use by all the owners of the residential lots and the subdivision and such common land may be included in the total gross acreage used for determining the number of lots permitted under the minimum lot size provisions of the residential zoning district within which it is located, subject to the following standards and conditions:
a.
Subdivision plat. All such common land shall be shown on the subdivision plat, to be approved by the Planning and Zoning Commission and the City Council and shall be shown as such on the record plat of such subdivision, subject to the restrictions set out below.
b.
Trust indenture. All common land shall be conveyed by the developer in fee simple absolute title by warranty deed to the trustees for the subdivision. The developer shall at the time of recording the record plat of such subdivision record a trust indenture providing that such common land shall be held and maintained by the trustees for the benefit, use and enjoyment of the lot owners, present and future, of such subdivision. Such trust indenture shall provide a uniform means of assessment to ensure that all such common land and any improvements constructed thereon shall be maintained by the trustees for the lot owners in compliance with the ordinances of this City and in such manner that such land and improvements will remain attractive and useful to the lot owners and shall not be injurious to the health, safety and welfare of the lot owners and of residents of surrounding areas or be detrimental to property values of surrounding areas. Such trust indenture shall also provide that the conveyance or change of ownership of any lot shall carry with it ownership in the common land and that no lot owner shall have the right to convey his/her interest in such common land except as an incident of the ownership of the platted lot even though such provisions are not expressly included in the deed of conveyance and shall further provide that no right or power conferred on the trustees by such indenture, in order to comply with the provisions of this paragraph, may be abrogated. All such trust indentures shall be submitted to the City Attorney for approval as to legal form and shall be recorded with the Recorder of Deeds of St. Louis County simultaneously with the recording of the final subdivision plat.
c.
Maintenance of common areas and streets. If the trustees of any such subdivision should fail to maintain any common area or street in accordance with the ordinances of the City or in such manner as to assure their intended use or in such manner as to injure the health, safety or welfare of the lot owners or of residents of surrounding areas or in such manner as to be detrimental to the property values of surrounding areas, the City may bring an action to compel the trustees or lot owners or both to correct any condition in such common area or street failing to meet any of the above standards. In the alternative, the City may correct any such condition in which event the City shall have the right to a lien against each lot in such subdivision for the pro rata cost of labor and material necessary to correct any such condition. The pro rata cost shall be determined by dividing the total cost, as determined by the City, by the number of lots in the subdivision. Any such lien shall bear interest at the rate per annum of two percent (2%) above prime and may be enforced by any means permitted by law or equity. In addition, the trustees or lot owners or both shall be responsible for any attorney's fees incurred by the City.
