(A) Open space design, conservation development, planned urban development (PUD).
(1) A better site design technique that concentrates dwelling units in a compact area in one portion of the development site in exchange for providing open space and natural areas in place of buildable area elsewhere on the site.
(2) The minimum lot sizes, setbacks, and frontage distances for the residential zone are relaxed in order to create the open space.
(B) Narrower streets.
(1) In many residential settings, streets can be as narrow as 22 to 26 feet wide without sacrificing emergency access, on street parking, or vehicular and pedestrian safety.
(2) Even narrower access streets or shared driveways can be used when only a handful of homes need to be served. Use of narrower streets will only be allowed on public streets by requesting a variance from Chapter 153 of this code of ordinances or in conjunction with the development of a PUD.
(C) Eliminating curbs and gutters. Elimination of curbs and gutters involves the use of grass swales and ditches as an alternative to curbs and gutters along residential streets. Eliminating curbs and gutters from public streets will only be allowed by requesting a variance from Chapter 153 of this code of ordinances or in conjunction with the development of a PUD.
(D) Alternative turnarounds. Alternative turnarounds are designs for end of street vehicle turnaround that replace cul-de-sacs and reduce the amount of impervious cover created in residential neighborhoods. Numerous alternatives create less impervious cover than the traditional 40-foot cul-de-sac. These alternatives include reducing cul-de-sacs to a 30-foot radius and creating hammerheads, loop roads, and pervious islands in the cul-de-sac center by requesting a variance from Chapter 153 of this code of ordinances or in conjunction with the development of a PUD.
(E) Alternative pavers. Alternative pavers are permeable surfaces that can replace asphalt and concrete and can be used for driveways, parking lots, and walkways. Commercially available pavers are used which contain void spaces for grass or clean, washed stone or gravel. Gravel, cobble, or mulch parking lots are prohibited except for development of one un-attached single-family dwelling private driveway.
