(A) New streets shall be so arranged to provide for the continuation of collector streets between adjacent properties when the continuation is necessary for convenient movement of traffic, effective fire and police protection, efficient provision of utilities, and where the continuation is in accord with the city's future land use plan.
(B) Whenever any subdivision abuts an existing street that is narrower than the standards indicated in this section, the developer shall dedicate right-of-way on the side abutting the subdivision to permit compliance with the right of way width for the designated street classification.
(C) Whenever any subdivision is proposed in such a manner that it will front on either one or both sides of an existing street, the developer shall, at his or her own expense, be required to make improvements to the existing street so that it complies with the standards imposed herein, as determined by the city.
(1) If such a development is proposed to front only one side of an existing street, the cost to improve the street to the standards set herein shall be borne equally by the developer and the city.
(2) If such a development is proposed so that it fronts both sides of an existing street, the cost to improve the street to the standards set herein shall be borne entirely by the developer.
(D) Where a subdivision abuts or contains an existing or proposed arterial or collector street with usage over 1,000 vehicles/day, the City Council may require that access to the street be limited by one of the following means:
(1) That lots be subdivided so that they back onto the arterial street and front onto a parallel local street, thereby creating double frontage lots, and that the developer install screening in a reserve strip along the rear lot lines of the lots;
(2) That the developer create a series of cul-de-sacs, U-shaped streets or short loops entered from and generally at right angles to the arterial street at 500 feet per min intervals, with the rear lot lines of the lots at the termini of the streets backing onto the minor arterial; or
(3) That the developer create a frontage road, separated from the arterial street by a planting strip, but having access thereto at suitable points.
(E) Any subdivision that exceeds a total of 50 lots shall be designed with two entrances accessing an adjoining street to provide alternate access to the subdivision in the event one of the entrances is blocked due to accidents, construction, or unforeseen circumstances. Any subdivision entrance servicing 25 homes or more shall be designed as a collector street.
