(a) In sloping terrain, streets shall generally run parallel to the contour of the land or preferably cross at a slight angle therewith. The general objectives are to avoid steep street grades, heavy concentrations of storm surface runoff, abnormal differential in building elevations at opposite sides of the street and excessive grading operations. Appropriate treatment shall be given to encourage the preservation of existing views, wooded areas, creeks and other attractive natural features of the plat.
(b) Where an approved plan designates an area to be preserved as natural areas, prior to clearing the land, the designated natural areas shall be protected during the entire construction period of improvements with orange vinyl latticed construction fencing of a minimum height of four (4) feet, secured with metal t-posts, demarcating the approved limits of clearing on the site. Where the established limits of clearing run through a tree of nine (9) inches or more diameter at breast height (DBH), the fencing shall circle the tree no closer than six (6) feet from the trunk or other methods approved by the Building Commissioner. The applicant shall be responsible for maintenance of the fencing at all times.
(Ord. 26-2006. Passed 3-28-06.)
Dead-end streets designed to be permanent shall be prohibited. In case a street over 150 feet in length is to be temporarily stub-ended, an interim turnaround will be required. A notation shall be placed on the final recorded plat that such temporary or interim turnaround area shall automatically be vacated upon authorized extension and construction of the street. The terminal end shall be extended to the boundary lines of the subdivision.
(Ord. 120-91. Passed 8-9-93.)
The length of a cul-de-sac street shall normally not be greater than 600 feet as measured from its intersection with another street to the start of the circular turnaround area. A "T" or "Y" shaped paved space may be approved in the place of the required turning circle. The terminal device shall not be extended to any boundary line and normally shall be at least 100 feet therefrom.
(Ord. 120-91. Passed 8-9-93.)
Where a subdivision abuts or contains an existing or proposed arterial street, involving heavy volumes of high speed vehicular traffic, the Planning Commission may require marginal collector streets, a nonacess reservation along the rear property and such other treatment as may be necessary for adequate protection of the proposed industrial, commercial or residential development to assure separation of through and local traffic. Before requiring any marginal streets or reverse frontage arrangements, the Commission shall take into account and decide upon the physical location of the major public utility lines as they relate to the existing and potential development along both side of the highway.
(Ord. 120-91. Passed 8-9-93.)
Industrial, commercial or residential building sites along railroads should normally have extra lot depth to permit deep setbacks for such building development and uses. The streets or roads serving such development shall be so located as not to interfere with the possible future construction of grade crossing or grade separation facilities along adjacent major traffic routes.
(Ord. 120-91. Passed 8-9-93.)
