(A) General. Any proposed subdivision containing land that is zoned or otherwise intended to be used for commercial, industrial or multi-family uses is subject to the design standards contained in this section, in addition to those standards applying to all subdivisions of land.
(B) Arrangement of lots and/or blocks. Proposed commercial, industrial or multi-family parcels shall be laid out in such a manner as to provide safe access; harmonious arrangements of land uses; separation of differing modes of transportation; areas for drainage runoff and, where applicable, retention areas; parking; landscape buffers; and utilities.
(C) Frontage. Each lot or parcel shall have the full required frontage on a public road meeting the minimum standards of this chapter.
(D) Streets. If access will be required for large trucks and/or heavy loads, the Commission may increase the construction and design requirements upon the recommendation of the County Engineer. Roads serving primarily non-residential traffic, especially truck traffic, shall not normally be extended to the boundary of adjacent tracts used or zoned for residential purposes, nor shall primarily residential roads be used for access to industrial subdivisions. Multi-family dwelling complexes shall be designed to discourage traffic from using streets designed and constructed primarily for single-family residential use.
(E) Alleys. Alleys may be permitted by the Commission to provide loading and service areas. The alleys shall have a right-of-way width of at least 20 feet and a pavement width of at least 16 feet.
(F) Other. The following items shall be addressed, either through the lot design or through notations placed upon the plat:
(1) Loading docks and parking. Loading docks, truck parking and/or truck turnaround areas shall be designated by the use of signs and pavement markings. These areas shall be separated from parking and access areas used by automobiles or pedestrian traffic. Public streets shall not be used for truck parking, standing or backing.
(2) Fire lanes. Fire lanes shall be required at all entrances and exits to structures and storage areas and at all locations of hydrants, Siamese connections, sprinkler controls or other locations deemed appropriate by the Commission. Fire lanes shall be marked by signs and pavement markings in accordance with current standards and specifications.
(3) Parking lots. Parking lots shall have a hard, dust-free surface and shall be designed to provide safe, well-defined points of ingress and egress. The Commission may require physical barriers, pavement markings, signs and landscaping as it deems necessary to properly channel traffic to designated parking entrances and exits.
(4) Buffers. Subdivisions containing land zoned for commercial or multi-family use shall contain landscaped buffer areas at least 15 feet in depth along all lot lines abutting land zoned for single-family or two-family residential use. Subdivisions containing land zoned for industrial use shall contain landscaped buffer areas at least 25 feet in depth along all lot lines abutting land used or zoned for residential use. The subdivision plans must show the planting details, including the type(s) and height of vegetation and the caliper of trees to be planted. The landscaped buffer shall be at least six feet in height and shall consist of materials which will form a dense screen within two years or an opaque fence shall be constructed to accomplish this purpose. The design and materials of the fence shall be shown on the plans.
(5) Snow storage. Developments which have parking, loading and driveway areas in excess of 40,000 square feet shall contain snow storage areas. Drainage plans shall include plans for the disposal of melt water.
(G) Drainage. A drainage plan meeting the specifications contained in § 156.097 shall be submitted. The system shall be designed so as to minimize the disposal of storm water off-site. The system shall make maximum use of on-site retention ponds or detention basins to minimize the downstream impact of the drainage from the site.
(H) Water and sewer facilities. The Commission may impose requirements as it deems necessary on the installation of water and sewer facilities.
