Where it is desired to subdivide a parcel of land that, because of its size or location, does not permit a normal lot or street area, there may be established a “place.” Such a place may be in the form of a court, non-connecting street or other arrangement, provided, however, that proper access shall be given to all lots from a dedicated place (street or court). If any dead-end place, court or cul-de-sac is more than 250 feet in length, it shall terminate in an open space, preferably circular having a minimum radius of 60 feet. Except in unusual instances, no dead-end street or place shall exceed 500 feet in length. All site improvements for places or planned area developments shall meet City standards for public improvements where possible to assure adequate protection of the public’s health, safety, and welfare. To this extent all access drives shall be paved to a minimum outlined in Section 170.07(14) and have geometric layout characteristics to provide for adequate parking areas and access by emergency vehicles. Sanitary sewer mains and manholes shall be provided so that each building is connected by means of an appropriate sized service line to the main that will be dedicated to the City along with appropriate access and maintenance easements. The water supply system shall likewise be constructed to public standards and dedicated to the City with appropriate easements to assure adequate domestic flow and metering as well as fire protection.
