(A) The road, street and alley design shall provide direct access to all lots and parcels of land within the subdivision and shall provide for continuity of arterial or collector roads and streets. The Plan Commission may require the extension of certain roads, streets or alleys, to the exterior boundary of the subdivision and may require the subdivider to provide a partial right-of-way along an exterior boundary line to correspond to an existing public right-of-way on adjoining lands, or for the purpose of extending arterial or collector roads.
(B) Alleys may be required in a subdivision of land designated as commercial or industrial districts. Residential alleys are not recommended.
(C) The minimum width of rights-of-way shall be 60 feet. A cul-de-sac shall terminate with an 80 foot diameter circle for auto traffic and a 100-foot diameter circle in commercial or industrial subdivisions. The length of a street ending in a cul-de-sacs is limited to 1,200 linear feet unless the Plan Commission determines that a longer length will not be detrimental to local traffic flow. Geometric designs for the turn-around other than a circle may be used at the terminus.
(D) Rights-of-way for alleys, when required by the Plan Commission in a commercial or industrial district, shall have a total width of 20 feet. All others shall not be less than 12 feet.
(E) All roads and streets must conform to the Thoroughfare Plan.
(F) (1) New half or partial streets are permitted only:
(a) Where the subdivider obtains an agreement in writing to dedicate and improve as required the other half of the street when the adjoining property is subdivided;
(b) Where essential to reasonable subdivision of a tract in conformance with the other requirements and standards of these regulations; or
(c) Where needed to complete existing streets.
(2) Where an existing street traverses or abuts the subdivision, the entire right-of-way required by these regulations, or as much as is possible within the subdivision, must be provided. The right-of-way must be measured from the centerline of the existing roadway.
(G) (1) Frontage roads separate local traffic from the higher speed through-traffic of major transportation arteries.
(2) Frontage roads may also be required by the Plan Commission to be located outside the right-of-way of arterial roads and streets when the average daily traffic exceeds 8,000 vehicles on two-lane roads and 15,000 vehicles on four-lane roads and the speed limit exceeds 40 mph, or when the number of curb cuts creates a traffic hazard or major flow impediment.
(3) Design of frontage roads shall be based on providing access to the property, maintaining circulation of traffic within the subdivision, providing for parking requirements and surface drainage.
Design of curb or edge of pavement radii shall conform to the applicable standards adopted by the town.
(4) Minimum sight distance at intersections should be sufficient to avoid the hazard of a collision between a vehicle starting from a “stop” position and the vehicle approaching the intersection from the left or right.
(H) Conduit for the installation of cable television cable shall be installed by the developer.
(I) All street plans shall conform to the current design standards adopted by the town. There shall be no private roads.
