(A) The arrangement of thoroughfares and streets shall conform as nearly as possible to a comprehensive plan. Streets normally shall connect with streets already dedicated in adjoining or adjacent subdivisions, or provide for future connections to adjoining unsubdivided tracts, or shall be a reasonable projection of streets in the nearest subdivided tracts. The arrangement of thoroughfares and streets shall be considered in their relation to the reasonable circulation of traffic, to topographic conditions, to runoff of storm water, to public convenience and safety and in their appropriate relation to the proposed uses of the area to be served.
(B) Minor streets should be so planned as to discourage their use by non-local traffic. Deadend streets will be permitted where topography or other conditions justify their use, and shall normally not be longer than 500 feet, including a turnaround which shall be provided at the closed end, with an outside curb radius of at least 40 feet and a right-of-way radius of not less than 50 feet.
(C) Where the plat to be submitted includes only part of the tract owned or intended for development by the subdivider, a tentative plan of a proposed future street system for the unsubdivided portion shall be prepared and submitted by the subdivider.
(D) When a tract is subdivided into larger than normal building lots or parcels, the lots or parcels shall be so arranged as to permit the logical location and opening of future streets and appropriate resubdivision, with provision for adequate utility connections for the resubdivision.
(E) Under normal conditions, streets shall be laid out so as to intersect as nearly as possible at right angles, except where topography or other conditions justify variations. The minimum angle of
intersection shall be 80 degrees. Street intersection jogs with an off-set of less than 125 feet shall be avoided.
(F) Wherever the proposed subdivision contains or is adjacent to a railroad right-of-way or the right-of-way of a limited access highway or thoroughfare, provision should be made for a marginal access street approximately parallel and adjacent to the boundary of the rights-of-way, or for a street at a distance suitable for the appropriate use of land between the street and right-of-way. The distance shall be determined with due consideration of the minimum distance required for approach connections to future grade separations or for lot depths.
(G) (1) Alleys shall be provided in commercial and industry districts, except that this requirement may be waived where other definite and assured provision is made for service access, such as off-street loading, unloading and parking consistent with and adequate for the uses proposed. Except where justified by special conditions, such as the continuation of an existing alley in the same block, alleys shall not be less than 20 feet.
(2) Deadend alleys may be approved if adequate turn-around facilities are provided at the closed end.
(H) Dedication of half streets will not be approved, except where it is essential to the reasonable development of the subdivision and in conformity with the other requirements of these regulations where it is found that it will be practical to require the dedication of the other half when the adjoining property is subdivided or where it becomes necessary to acquire the remaining half by condemnation so it may be improved in the public interest.
(I) (1) For all public ways hereafter dedicated and accepted, the minimum right-of-way widths for streets, thoroughfares, alleys or pedestrian ways included in any subdivision shall not be less than the minimum dimensions for each classification as follows:
Alley | 20 feet |
Major thoroughfare | 80 feet |
Marginal access street | 24 feet |
Minor street | 40 feet |
Pedestrian way | 8 feet |
Secondary thoroughfare | 60 feet |
(2) Where existing or anticipated traffic on major and secondary thoroughfares warrants greater widths of rights-of-way, these shall be required.
(J) (1) The grades in all streets, thoroughfares, collector streets, minor streets and alleys in any subdivision shall not be greater than the maximum grades for each classification as follows:
Alley | 8% |
Major thoroughfare | 5% |
Minor street | 8% |
Secondary thoroughfare | 5% |
(2) In addition, there shall be a minimum grade on all streets and thoroughfares of not less than 1%.
(K) All proposed streets shall be offered for dedication as public streets. No private streets will be allowed.
