A Planned Residential Development shall comply with the following supplemental requirements.
(a) Landscaping. All development, street right-of-ways and corridors, and common open space shall be landscaped according to an overall plan and shall be implemented by phases as units are completed and weather permits. Plantings, walls, fencing, and screens shall be so designed and located as to optimize privacy and aesthetic quality without encroaching upon required automobile site distances. Natural wooded areas shall be preserved and maintained for landscaping and screening to the greatest extent possible.
(b) Topography - Natural Features. The PRD shall be designed to take advantage of the topography of the land in order to utilize the natural contours, and to minimize destruction or alteration of water courses, natural vegetation, trees, and topsoil. The natural features and other distinctive characteristics of the site shall be integrated into the plan to create variations in the arrangements of buildings, open spaces and site features. A program for preserving and quickly recreating an attractive landscape environment shall be part of any development.
(c) Grading. Grading and site preparation for areas other than building sites, streets, sidewalks and utilities shall be limited to disturbing the minimum amount of vegetation and other topographic features.
(d) Development Layout. Dwelling units shall be grouped or clustered so as to break up the development arrangement, maximize privacy, collect and maximize the common open space and promote the individual character and coordinated layout of each lot, cluster and grouping. Streets and cul-de-sacs shall be laid out so as to utilize natural contours and discourage through and high speed traffic.
(e) Solid Waste Storage and Disposal. All rubbish and garbage shall be stored in wholly screened or fenced storage areas acceptable to and regulated by the City.
(f) Circulation.
(1) The vehicular circulation system and parking facilities should be designed to fully accommodate the automobile, service equipment, and emergency safety vehicles with safety and efficiency, but without permitting said facilities to dominate and destroy the form of the area. Driveways for group developments should intersect with local streets at locations where the traffic can be controlled and operated effectively with the minimum interference to the capacity and flow on the existing streets.
(2) The pedestrian circulation shall be designed through an inter-connecting walkway system to promote easy and direct barrier free access to all areas of the development. The walkways do not necessarily have to be at the front of the units and next to the streets. Walkways through common open space should be encouraged.
(3) Wherever possible, the major vehicular and pedestrian circulation patterns shall be completely separate and independent from one another.
(4) Street and sidewalk alignments, and the alignments for utilities should be parallel to contours, in valleys or on ridges where possible, in common open areas, and, as permitted by the Planning Commission and Council, in areas served by private drives or cul-de-sac streets.
(5) There shall be no direct access from individual residences to a major thoroughfare and direct access from residences to collector thoroughfares shall be minimized.
(6) Connection to the City’s sidewalk network and any hike and bike trails, if applicable, shall be provided unless it is not feasible as determined by the City.
(g) Phased Development. If the development is to be implemented in phases, each phase shall have adequate provision for access, parking, storm water management and other public improvements to serve the development in accordance with the applicable criteria set forth. Each phase shall be provided with temporary or permanent transitional features, buffers, or protective areas in order to prevent damage to completed phases, to future phases and to adjoining property. A performance bond on all improvements and amenities shall be furnished to the City prior to initiating construction on the first phase of the development.
(h) Compliance with Other Ordinances. In addition to complying with the requirements of this chapter, an applicant applying for a Conditional Use Certificate for a Planned Residential Development shall comply with the appropriate provisions of the City's Subdivision Regulations and other Sections of the Zoning Code not in conflict with the specifications contained in these regulations.
