A. No yards or setbacks or minimum lot areas are required in a planned unit development (PUD) except as provided in subsection B of this section.
B. The city may require a buffer strip to be provided along the outer perimeter of the PUD. Such buffer shall be left in a natural state, or it may be landscaped in a formal manner. The buffer shall be of adequate width to maintain compatibility with adjacent existing areas whose setbacks were based on the standards of the underlying zone. Purchasers of lands that contain the buffer area shall have a provision in their warranty deed, or a provision in the restrictive covenants, requiring the retention and maintenance of such buffer area, by either the homeowner or the homeowners' association.
C. The intensity of residential development in a PUD shall be established, initially, by applying the density permitted by the residential zone category in which the PUD is to be established. These permitted densities, generally, are as follows:
Zone District
| Density In Dwelling Units Per Gross Acre (Unless Otherwise Specified)
|
Zone District
| Density In Dwelling Units Per Gross Acre (Unless Otherwise Specified)
|
A single-family district | 4.98 du/ac |
A-1 single-family dwelling district | 3.75 du/ac |
A-3 single-family dwelling district | 4.05 du/ac |
A-4 single-family dwelling district | 5.22 du/ac |
A-5 use district | 0.50 du/net acre |
B multiple dwelling district | 17.42 du/ac |
B-3 use district | 10.87 du/ac |
The permitted density in the underlying zone/district shall act as a guide. As a general guideline, however, the planned unit development may exceed these basic densities by as much as thirty percent (30%) in the A districts, and by as much as twenty percent (20%) in the B and B-3 districts.
Increases in density may be allowed only if the applicant can demonstrate the following:
1. The increased density will result in a more creative or compact design that will produce a more interesting development, or will protect some significant features of the natural environment.
2. The increased density will result in additional common open space for passive or active recreation in addition to the basic five percent (5%) required in subsection E of this section.
3. The increased density will not place a burden on the capacity of roads, water, sewage and drainage facilities.
4. The increased density will not negatively impact adjacent developed or developing areas.
D. Building heights shall be controlled by the height limits set out in the underlying zone district.
E. A PUD shall provide a minimum of five percent (5%) of the total land area in common open space for active and passive recreation.
F. Buildings and streets shall be designed and located to take advantage of and complement the natural terrain.
G. A PUD shall be served by the city water system.
H. A PUD shall be served by the city wastewater treatment system.
I. Individual wells and individual sewerage systems are prohibited in a PUD.
J. Storm water shall be retained on site.
K. Adequate off street parking shall be provided for each dwelling unit in quantity and in locations that do not promote the parking of vehicles in a manner that blocks any part of a traveled road, street or a pedestrian walkway.
L. Sightlines at road or street intersections shall be maintained for the safety of both vehicular and pedestrian movement. No buildings or other structures or vegetation shall be located so as to block sightlines at such intersections.
M. Every dwelling unit shall have access to a public or private street, via laneways, pedestrian walkways, or other access related easements.
N. The city council or the planning and zoning commission may require a traffic impact study from the PUD applicant if in its opinion the increased density requested is such that street capacities may be negatively affected by increased traffic or that the safety and enjoyment of the living environment may be negatively impacted.
O. Street lighting may be required by the city council on recommendation of the planning and zoning commission.
P. The planning and zoning commission may recommend, and the city council may impose, any other development standard it deems necessary or desirable. (Ord. 1069, 1-13-2003)
