Where a park, playground, school, or public access to water frontage which is shown in the comprehensive development plan is located in whole or in part in the proposed subdivision, the Commission shall request the dedication of such area within the subdivision. The subdivider shall pay for only that portion of the cost of the public site that benefits his subdivision as determined by the Commission. Every subdivider of land for subdivisions not containing public sites shall be requested to provide land or payment in lieu thereof for that portion of benefits from public sites accruing to his land as determined by the Commission. The Commission shall wherever possible, establish the preservation of all natural features which add value to residential developments and to the community, such as large wooded areas, watercourses, beaches, areas of historical significance, and similar irreplaceable assets.

* The minimum required lot depth of 120 feet is assumed.
For slope areas where the average topographic slope is 15 per cent or greater, refer to Chapter 1111, Hillside Regulations.
SUBDIVISION DESIGN STANDARDS
The additional utility easement for a fifty (50) foot right-of-way may be required in order to maintain traffic flow during construction or repair of utilities.
1107.05 Example for Cul-de-sac and Loop Streets
CUL-DE-SAC
LOOP STREET
EXAMPLE OF A SUBDIVISION
1. 15 foot easement for planting screen to provide protection from nonresidential use.
2. 10 foot walk easement gives access to school.
3. Cul-de-sac utilizes odd parcel of land to advantage.
4. Turn-around right-of-way 100 feet in diameter.
5. Street trees planted approximately 50' apart where no trees exist.
6. Additional building setback improves subdivision entrance.
7. Street intersections of right angles reduce hazards.
8. Lot side line centered on street end to avoid car lights shining into residence.
9. Residences opposite street end set back farther to reduce glare from car lights.
10. Three-way intersections reduce hazards.
11. Property lines on 30' radii at corners.
12. Lot side lines perpendicular to street right-of-way lines.
13. Secondary roadway eliminates hazard of entering major thoroughfare from individual driveways.
14. Neighborhood park located near center of tract. Adjacent lots wider to allow for 15 foot protective side line setback.
15. Pavement shifted within right-of-way to preserve existing trees.
16. 10 foot walk easement provides access to park. Adjacent lots wider to allow for 15 foot protective side line setback.
17. Variation of building line along straight street creates interest.
18. Screen planting gives protection from noise and lights on thoroughfare.
19. Lots backing to uncontrolled land given greater depth for additional protection.
20. Low planting at street intersection permits clear vision.
21. Wider corner lot permits equal building setback on each street.
22. Platting of block end to avoid siding properties to residences across street.
