In addition to the general development standards described in Section 1165.04 above, residential PUDs shall meet the following development standards:
(a) Clustering Residential Development and Required Open Space.
Clustering residential density is encouraged to provide required common open space. A minimum of twenty percent (20%) of the land developed for residential purposes in a PUD-RS project shall be reserved for common open space. This required amount of common space shall be established as common open space, under one ownership, and provision shall be established for maintenance and care. The legal articles relating to any organization of property owners in the development charged with such open space maintenance shall be submitted to the Municipality and publicly recorded with Lorain County Recording Office. The Municipal Council may require as a condition of final approval, any evidence deemed necessary to document that the required common space will remain in its stated condition as long as the development exists (including such as legal documents, deed restrictions, conservation easements, etc.).
(b) Clustering Residential Density.
To achieve a clustering of residential density and to provide for the required common open space, the lot area requirements for residential land uses may be reduced from the densities required under the district(s) applying to the property at the time of application by up to twenty percent (20%). The lot width and yard requirements for residential lots may also be reduced as needed to accommodate a variety of structural patterns, clustering designs, and housing types.
(c) Residential Dwelling Types.
Along with clustering residential density, a PUD-RS may include a mixture of dwelling types, including single-family detached dwellings, two-family units, zero lot-line units, and multiple-family units provided the maximum density requirements of Section 1165.05 (b) are not exceeded.
