It is the purpose of this chapter to obtain a more creative and imaginative residential environment than would otherwise be possible through strict application of the minimum requirements of the R-L Low Density Residential District, while maintaining the same population densities established in the R-L District. The single family cluster developments are intended to achieve, in a unified development, more flexible spacing of lots and buildings and encourage the following:
(a) In larger projects, a wider variety of dwelling types including conventional single family and single family cluster dwellings;
(b) A more efficient use of land than is generally possible in the R-L zone, resulting in decreased improvement costs;
(c) The creation of functional and interesting residential areas;
(d) The provision of readily accessible recreation and open spaces;
(e) The conservation of natural landscape amenities; and
(f) The separation of pedestrian and vehicular circulation.
