(A) Streets shall be designed to comply with the standards set forth in the city’s Public Works Design Manual, standard specifications, and details.
(B) Proposed roads shall conform to the state, county and/or city plans as have been prepared, adopted and/or filed as prescribed by law.
(C) Roads shall be logically related to the topography so as to produce usable lots and reasonable grades. Access shall be given to all lots and portions of the tract in the subdivision, and to adjacent unsubdivided territory unless the topography clearly indicates that the connection is not feasible. Reserved strips and land-locked areas shall not be created. Wherever a tract to be subdivided borders an existing half or partial road, the other part of the road shall be platted within the tract.
(D) If adjoining areas are not subdivided, but may be subdivided in the future, the arrangement of streets must make provision for the proper projection of streets into adjoining areas by carrying the new streets to the boundaries of the new subdivision at appropriate locations.
(E) Streets shall not be arranged in a way that will cause undue hardship to owners of adjoining property.
(F) Local roads shall be laid out to discourage their use by through traffic.
(G) Where possible, arterials shall be protected for use by service roads or marginal access roads.
(H) Cul-de-sac streets are discouraged when through streets are practical. Cul-de-sac streets shall be no longer than 500 feet, unless otherwise approved by the City Council at the recommendation of the City Engineer due to topography, water, or other circumstances.
(I) In those instances where a street is terminated pending future extension in conjunction with future subdivision, and there is more than 200 feet or two dwelling units accessed between the dead end and the nearest intersection, a temporary turnaround that meets the following requirements shall be placed at the closed end:
(1) The temporary cul-de-sac must be placed inside a temporary roadway easement if it is located outside of street right-of-way.
(2) The temporary cul-de-sac shall be paved with bituminous within one year of construction. Other surfaces may be considered and allowed by the Zoning Administrator on a case by case basis.
(3) The developer shall submit a cash escrow in an amount determined by the City Engineer for the removal of the temporary cul-de-sac and restoration of the area, limited to placement of sod and asphalt driveway within the temporary roadway easement.
(4) Temporary “dead-end” public streets associated with providing access for future extension to and through adjacent undeveloped property require concrete curb and gutter installation. Temporary dead-end streets that will be extended as part of a future phase of a development shown on an approved preliminary plat do not require concrete curb and gutter along the radius of the cul-de-sac.
(J) In the platting of small tracts of land fronting on limited access highways or arterials where there is no other alternative, a temporary entrance may be granted with an interim use permit. As neighboring land becomes subdivided and more preferable access arrangements become possible, the interim use permit shall become void.
(K) Access of local streets or driveways onto state and county state aid highways shall not be permitted at intervals of less than 500 feet.
(L) Intersections.
(1) The angle formed by the intersecting of streets shall not be less than 60 degrees with 90-degree intersections preferred.
(2) Intersections of more than four corners shall be prohibited.
(3) Constructed roadways of street intersections shall be rounded by a radius of not less than 20 feet.
(M) Concrete curb and gutter shall be included as a part of the required street surface improvement and shall be designed for installation along both sides of all roadways.
