The layout and design of all subdivision developments and the content of all plats, engineering plans, documentation and other required submission should be in accordance with the standards as contained herein and/or as may be adopted by the Town pursuant to the provisions of subsection 10-14-8A of this chapter.
a. Subdivision Plans Consistent With Street Plan: Subdivision plans shall be consistent with the Master Street Plan as adopted by the Town, as follows:
(1) Collector Streets (Feeder): Where the area of a proposed subdivision includes any collector class streets as shown on the Major Street Plan, the subdivision plan shall incorporate such in the location shown on the Street Plan and the approval of the final plat shall include the dedication of the right- of-way and its improvements in accordance with the applicable Town standards.
(2) Minor Streets (Local Service): Where the area of a proposed subdivision includes any minor class streets, as shown on the Major Street Plan, the subdivision plan shall provide for such street in the approximate location shown on the Street Plan and the approval of the final plat shall include the dedication of the right-of-way and its improvements in accordance with the applicable Town standards. (Any proposed street that would intersect with any composed street that would intersect with any County or State street must have permission from them on their letterhead.)
(3) Deletion Or Realignment: No subdivision plan which proposes the deletion or significant realignment of any street shown on the Major Street Plan shall be given preliminary approval unless and until the Plan shall have been amended in accordance with State law.
b. Relationship To Adjacent Streets: The proposed street system shall properly align and be compatible with adjacent streets.
c. Access To Adjacent Properties: In order to facilitate the development of an adequate and convenient circulation system within the Town and to provide access for the logical development of adjacent properties, the Town may, as a condition of approval, require the subdivision plan to include one (1) or more temporary dead end streets (stub streets) which extend to the boundary of the subdivision. All such stub streets shall be fully developed to the boundary of the subdivision. Any plan for the subsequent development of the adjacent property shall provide for the continuation of any such stub street.
2. Right-Of-Way Width: The minimum width of right-of-way for streets shown on the Major Street Plan shall conform to the width as designated on the Plan. The minimum right-of-way width for the streets not shown on the Plan shall be as follows:
| |
Minor class | 60 feet |
Collector class | 80 feet |
3. Surfacing And Width Of Streets: All streets within and adjacent to the subdivision shall be hard surfaced. The width of the hard surfacing and the location and type of other required street improvements shall be in accordance with applicable street cross section standards adopted by the Town Council.
4. System Design Standards For Streets And Roads:
a. Reverse Curves: Reverse curves shall have a tangent of at least one hundred feet (100'), unless in the opinion of the Planning Commission such is not necessary.
b. Street Intersection: Streets shall intersect each other as nearly as possible at right angles. Minor streets shall approach the major or collector streets at an angle of not less than eighty degrees (80°). Offset in street alignment of more than fifteen feet (15') or less than one hundred twenty feet (120') shall be prohibited.
c. Street Grades: The maximum grade of any street in the subdivision shall be eight percent (8%). Where the observance of this standard is not feasible, the Town Council, subject to the prior recommendation of the Planning Commission, shall have the power to grant an exception when special pavement surfaces and adequate leveling areas are installed and in the opinion of the Town the best subdivision of the land is thereby secured.
d. Street Curves: Where the street lines within a block deflect from each other at any one (1) point more than ten degrees (10°), there should be a connecting curve. The radius of the curve for the inner street line should be not less than three hundred fifty feet (350') for collector class streets, two hundred fifty feet (250') for an important minor class street, and one hundred feet (100') for minor streets.
e. Curbs: Where curbs are required, said curbs at intersections shall be rounded with curbs having a minimum radius or fifteen feet (15') for minor streets and twenty five feet (25') for collector streets. Property lines at street intersections should be rounded with a curve where necessary to fit the curb radius.
f. Street Names: New street names should not duplicate those already existing. A street obviously a continuation of another already in existence should bear the same name. Before the street is named, the proposed name must be submitted to and approved by the Town.
g. Cul-De-Sacs: Cul-de-sacs (dead end streets) shall be used only where unusual conditions exist which make other designs undesirable. Each cul-de-sac shall have a minimum right-of-way width of sixty feet (60') and must be terminated by a turnaround of not less than one hundred feet (100') in diameter. The maximum length of a cul-de-sac street shall be four hundred feet (400'). Surface water must drain away from the turnaround, except that where surface water cannot be drained away from the turnaround along the street due to grade, necessary catch basins and drainage easements shall be provided.
h. Easements: Easements of not less than eight feet (8') on each side of rear lot lines and side lines will be required where necessary for poles, wire, conduits, sewers, gas and water mains, and other public utilities. Easements of greater width may be required along property lines where necessary for surface overflow or for the extension of main sewers or similar utilities.
B. Block Design Standards:
1. Length: The maximum length of blocks generally shall be eight hundred feet (800'), and the minimum length of blocks shall be four hundred feet (400'). In blocks over eight hundred feet (800') in length, the subdivider may be required to dedicate a walkway through the block at approximately the center of the block. Such walkways shall not be less than ten feet (10') in width.
2. Width: The width of blocks generally shall be sufficient to allow three (3) tiers of lots with lots being one hundred twenty feet (120') in width.
3. Use: Blocks intended for business or industrial use shall be designed especially for such purposes with adequate space set aside for off-street parking and delivery facilities.
1. Building Sites: The lot arrangement, design and shape shall be such that lots will provide satisfactory and desirable sites for buildings, be properly related to topography and conform to requirements set forth herein. Lots shall not contain peculiarly shaped elongations solely to provide necessary square footage, which would be unusable for normal purposes.
2. Conformance To Zoning Provisions: All lots shown on the subdivision plat must conform to the minimum requirements of the zone in which the subdivision is located.
3. Corner Lots: Corner lots shall have ten feet (10') extra width to accommodate the additional setback requirements.
4. Angle Of Lot Lines: Side lot lines shall be approximately at right angles, or radial to the street line, except where topographic conditions make it advisable to have side lot lines deflect at sharper angles.
5. Remnants Of Lots: All remnants of lots below minimum size left over after subdividing a larger tract must be attached to adjacent lots rather than allowed to remain as unusable parcels. Protection strips shall not be permitted.
6. Multiple Ownership Of Lots: Where the land covered by a subdivision includes two (2) or more parcels in separate ownership and the lot arrangement is such that a property ownership divides one (1) or more lots, the land in each lot so divided shall be transferred by deed to single ownership before approval of the final plat, and such transfer recorded in the County Recorder's Office before being certified to the Planning Commission by the subdivider or the subdivision shall be considered as a joint project and the final plat shall be signed by all affected property owners.
7. Water, Sewer, Irrigation: Each lot within the subdivision shall be served by the Town water system through lines providing flow for both culinary and fire purposes. Each lot within the subdivision shall be served by the Town sewer system, except that the Town may authorize the development of a subdivision project utilizing septic tanks or other individual disposal facilities where it is determined that connection of the subdivision project to the sewer system is not reasonably feasible. Each lot in the subdivision may be served by an approved irrigation system.
8. Culinary Water And Irrigation Systems:
a. Culinary: All subdivision development applications shall dedicate to the Town, as part of the development approval process, documented and perfected water rights sufficient to service the water needs of the development. All subdivision development must hire an Engineer to test their water system to see if there will be enough pressure to service the water system. All culinary system plans must be approved by the State before construction and after construction. "Water rights sufficient to service the water needs of the development" shall be defined, for residential development, as 1.32 acre-feet per dwelling, assuming a twelve thousand (12,000) square foot lot. This figure is based on State standards and Town historical usages of 0.675 acre-feet of water for indoor use, and 0.645 acre-feet of water for outdoor use, the latter figure being subject by the Town Council or the Town appointed Engineer for lot size variations and water conserving landscaping, or as determined by State regulations.
b. Irrigation: Each lot in the subdivision may be served by an approved irrigation system. (Ord. 17-02, 3-16-2017)
