A. The quality of design of the urban area is dependent on the quality of design of the individual subdivisions that compose it. Good community design requires the coordination of the efforts of each subdivider and developer of land within the urban area. Therefore, the design of each subdivision shall be prepared in accordance with the principles established by the general plan for land, circulation, community facilities and public utility services and in accordance with the following general principles:
1. It is intended that the urban area should be designed as a group of integrated residential neighborhoods and appropriate commercial and industrial and public facilities. The neighborhood as a planning unit is intended as an area principally for residential use, and is of a size that can be served by one elementary school. Space for religious, recreational, education and shopping facilities to serve the residents of the neighborhood should be provided and designed as an integral part of each neighborhood;
2. The size of lots and blocks and other areas for residential, commercial, industrial and public uses should be designed to provide adequate light, air, open space, landscaping, off street parking and loading facilities;
3. The arrangement of lots and blocks and the street system should be designed to make the most advantageous use of topography and natural physical features. Tree masses and large individual trees should be preserved. The system of sidewalks and roadways and the lot layout should be designed to take advantage of the visual qualities of the area; and
4. Circulation within the urban area shall be provided in accordance with the following design criteria:
a. Each subdivision shall provide for the continuation of all arterial streets and highways as shown on the major street plan. Arterial streets should be located on the perimeter of the residential neighborhood;
b. Minor streets should be designed to provide access to each parcel of land within the residential neighborhood and within industrial areas, and in a manner that will discourage use by through traffic. They should be planned so that future urban expansion will not require the conversion of minor streets to arterial routes;
c. Collector streets should be designed to provide a direct route from other minor streets to the major street system;
d. Ingress and egress to residential properties should be provided only on minor streets; and
e. Pedestrianways should be separated from roadways used by vehicular traffic. Sidewalks should be designed to provide all residential building sites with direct access to all neighborhood facilities, including the elementary school, parks, playgrounds, churches and shopping centers.
