(A) All new or modified public streets constructed after the date of adoption of this chapter shall meet the street construction standards of this section’s table unless waivers are granted in accordance with § 154.003 of this chapter.
(B) If a private street that is proposed for acceptance as a public street does not meet the minimum standards of this section’s table, including the width of right-of-way, that street must be improved to meet the requirements before being accepted as a public street unless waivers are granted in accordance with § 154.003 of this chapter.
(C) All changes of centerline grade shall be connected by vertical tangent curves that provide for clear visibility to satisfy the requirements of § 154.009 of this chapter.
(D) Intersections of public streets shall be at angles as close to 90 degrees as possible and in no case shall two public streets intersect at an angle smaller than 75 degrees. To this end, where one public street approaches another between 75 and 90 degrees, one or both streets shall be curved approaching the intersection. Any variation of an intersection angle from 90 degrees shall be approved by the Town Council or its designee only upon a review of evidence submitted by the applicant that demonstrates that a lesser angle is necessary.
(E) Cross (four-corner) public street intersections shall be aligned on opposite sides of the through street insofar as possible. If it is not possible to align the intersecting streets, a distance of at least 200 feet shall be maintained between centerlines of offset intersecting public streets.
(F) Public street intersections and curves shall be designed to permit adequate visibility for both pedestrians and vehicular traffic in accordance with § 154.009 of this chapter.
(G) All public streets shall have suitable drainage facilities to provide for adequate removal of storm water to prevent flooding and erosion.
(H) Curbs and gutters shall be required on all public streets.
(I) Handicapped accessible sidewalks shall be constructed on at least one side of all public streets.
(J) Shoulders shall be constructed to the same specifications as the traveled way so as to be suitable for use by vehicles of all types that may be reasonably expected to use the travel way of the street.
(K) The final grade level of ditch bottoms along a public street shall be a minimum of six inches below the subgrade level of the street.
(L) All new public streets constructed after the date of adoption of this chapter shall not be isolated from existing public streets by intervening private streets. That is, new public streets must either intersect existing public streets or there shall be a continuous path from a new public street through other new public streets to one or more existing public streets.
