The arrangement, character, extent and location of all streets and driveways shall conform to the Land Use and Thoroughfare Plan of current adoption by the Municipality of Twinsburg. Where such streets are not shown on the Land Use and Thoroughfare Plan, the arrangement of the streets in the subdivision shall either provide for the continuation or appropriate projections of existing principal streets in surrounding areas or conform to a plan for the neighborhood approved or adopted by the Planning Commission to meet a particular situation where topographical or other conditions make continuance or conformance to existing streets impractical. Provisions shall be made for future extension of streets and drives to adjacent unplatted lands so that the entire area can be served with a coordinated street system.
(a) Street Names. Street names shall not duplicate or be similar to any other existing road names in the Municipality. The Planning Commission shall approve all street names.
(b) Dedication of Streets to Public Use. The developer shall dedicate to public use all land within the right-of-way of all public streets within a subdivision.
(c) Street Design Layout.
(1) Residential subdivisions: The road design should encourage appropriate traffic circulation and provide adequate access by fire fighting apparatus and emergency vehicles. Provision shall be made by the developer for continuance of the road pattern where required by the Planning Commission in accordance with these regulations.
(2) Commercial subdivisions: The street pattern within commercial subdivisions should be planned to connect with arterial or collector streets so as not to generate traffic on local streets or near residential areas. Streets from commercial subdivisions should intersect arterial or collector streets so as to cause the least possible interfer-ence with traffic movement on such streets.
(3) Industrial subdivision: The street pattern within industrial subdivisions should be planned to connect with arterial or collector streets so as not to generate traffic on local streets. Streets from industrial subdivisions should intersect arterial or collector streets so as to cause the least possible interference with traffic movement on such streets. Streets from industrial subdivisions shall not directly connect with local streets within a residential subdivision.
(d) Classification of Streets and Private Driveways. Streets shall be classified as follows:
(1) Interstate highways, freeways and expressways. Interstate highways, freeways and expressways shall be planned for continuation of major interstate and interstate high speed traffic of large volumes between areas within and outside of the state. All location of such highways and intersections shall be by Federal, State and City agreement.
(2) Arterial streets. Arterial streets shall be planned for continuation of movement of fast traffic between points of heavy traffic generation and from one section of the community to another. They shall contain as few intersections with minor streets as possible. Such thoroughfares should traverse the community and should be spaced approximately one (1) mile apart.
(3) Collector streets. Collector streets shall provide a traffic route from local streets to arterial streets. Collector streets normally contain a relatively large number of intersections with local streets and few intersections with arterial streets. These streets should be spaced at least one-fourth mile apart. No private driveways shall abut upon a collector street.
(4) Local streets. Local streets shall provide direct and full access to each abutting lot, site or structure, and shall be laid out so that their full use by through traffic will be discouraged. Normally each end of a local street shall connect into another local street, collector street, or arterial street.
(5) Loop streets. Loop streets shall provide direct and full access to each abutting lot, site or structure and shall be laid out so that their use will in general accommodate only the lots, sites and structures fronting the street or drive and discourage through traffic. Each end of a loop street shall connect to the same local street, collector street, or arterial street and shall not be cross connected to any other local collector or arterial street at any portion throughout its length.
(6) Cul-de-sac or dead end streets. Cul-de-sac and dead end streets shall be constructed with a cul-de-sac or turn around area and be designed to provide direct and full access to each abutting lot, site or structure. The cul-de-sacs or dead end streets shall be laid out to accommodate only those lots, sites and structures fronting the street and cul-de-sac.
(7) Six unit drives (Private). Six unit drives may be in general private driveways to service up to six building sites on one lot cluster site.
(8) Two unit drive (Private). Two unit drives shall be in general private driveways to service building sites for two lots, two building sites and/or structures containing two units or double occupancy or use.
(9) Single unit drives (Private). Single unit drives shall be in general private driveways to service building sites for one lot, one building site and/or single structures designed for the purpose of a single occupant or use.
(e) Streets, Drives and Driveway Right-Of-Way Width for Public and Private Use. Minimum permanent unobstructed public or private right of way, easement or common area width for street, drive and driveway areas for street and drive pavements, curbs, treelawns, sidewalks, sewers, water lines, driveway aprons and utilities shall conform to the following minimum widths:
(1) Interstate Highways, Freeways and Expressways by agreement with the City.
(2) Arterial and Collector streets, eighty feet (80').
(3) Local streets and drives, loop streets and drives and dead end streets and drives, sixty feet (60').
(4) Private drives for single, two and six unit occupant uses, no easement or right of way area required.
(f) Utility Easements. Easements of minimum width of twelve feet (12') shall be provided on each side of rights of way, easements of common areas for private streets and drives proposed for access to sites proposed for lots and/or structures for three (3) or more units.
(g) Pavement Widths, Grades and Design Speed. The following minimum pavement widths as measured from back of curb to back of curb when curb is required, requirement of curb, percentage of grade and design speed (not necessarily legal speed) shall be used for all designs of streets and drives for public or private development.
