(A) Roads. The design of all roads shall be considered in relation to existing and planned roads, to reasonable circulation of traffic, topographical conditions, to runoff of storm waters, and to the proposed uses of the areas to be served.
(1) Where adjoining areas are not subdivided, the arrangement of roads in new subdivisions shall make provisions for the proper projection of roads. When a new subdivision adjoins unsubdivided land susceptible of being subdivided, then the new road shall be carried to the boundaries of such unsubdivided land. Where new roads extend existing adjoining roads, their projections shall be at the same or greater width, but in no case, less than the minimum required width.
(2) The minimum road design standards of the city, including road width and grade standards, shall be observed by the subdivider, as set forth in § 155.16.
(3) Straight segments of at least 50 feet in length shall be introduced between reverse curves on city streets and alleys.
(4) Insofar as practical, road intersections shall be at right angles and no intersection shall be at an angle of less than 45 degrees. It must be evidenced that safe and efficient traffic flow is encouraged.
(5) Private roads shall not be approved nor shall public improvements be approved for any previously existing private road.
(6) Where a proposed plat is adjacent to a highway, the City Council may require the subdivider to provide a service road along the right-of-way.
(7) The road arrangements shall not be such as to cause hardship to owners of adjoining property in platting their own land and providing convenient access to it.
(8) At road intersections, curb lines shall be rounded at a radius of not less than 15 feet.
(B) Easements.
(1) Utility easements at least ten feet wide shall be provided for utilities where necessary. They shall be centered on rear and other lot lines or within alley rights-of-way. They shall have continuity of alignment from block to block. At deflection points, easements for pole line anchors shall be provided where necessary.
(2) Where a subdivision is traversed by a water course, drainage way, channel, or road, there shall be provided a storm water easement or drainage right-of-way substantially with the lines of such water course, together with such further width or construction or both as will be adequate for stream channel, but also adjoining areas that have been subject to flooding in years of heavy runoff.
(C) Lots.
(1) Where possible, side lot lines shall be at right angles to straight or radial to curved road lines. Each lot shall front on a public road or highway. Lots with frontage of two parallel roads shall be permitted only under unusual circumstances.
(3) Lot remnants which are below the minimum lot size must be added to adjacent or surrounding lots rather than be allowed to remain as an unusable outlot or parcel unless the owner can show plans consistent with the purpose of this chapter for the future use of such remnants.
