(a) Internal service roads may be required to provide adequate access to multiple lots. In particular, the Planning Commission may require the development of internal service roads where such facilities can provide access to signalized intersections, where service drives may minimize the number of driveways, and as a means to ensure that traffic is able to more efficiently and safely ingress and egress. Internal service roads shall consist of either "frontage roads" or "reverse frontage roads" including the driveways that connect to adjacent streets or parking areas. All internal service roads shall be designed, constructed and maintained in accordance with the following standards:
(1) Location - Frontage roads and reverse frontage roads shall generally be parallel to the front property line and may be located either in front of, or behind, principal buildings and may be placed in required yards. In considering the most appropriate alignment for an internal service road, the Planning Commission shall consider the setbacks of existing and/or proposed buildings and anticipated traffic flow for the site.
(2) Alignment - The alignment of the service road can be refined to meet the needs of the site and anticipated traffic conditions, provided the resulting terminus allows the drive to be extended through the adjacent site(s). This determination may require use of aerial photographs, GIS property maps, topographic information and other supporting documentation as required for the respective development application.

(3) Access Easement - An internal service road shall be wholly located within an access easement permitting traffic circulation between properties. The easement shall be recorded with the Butler County Recorder's Office as a condition of approval.
A. In any development containing commercial, retail, service related uses or mixed use developments containing a residential land use component, an internal service road shall have a minimum pavement width of 24 feet, measured face to face of curb with an approach width of 36 feet at intersections.
B. The frontage road or service drive shall be constructed to meet the City of Trenton public street construction standards for base and thickness of asphalt or concrete.
C. In any development containing residential land uses exclusively, a frontage road shall have a minimum pavement width of 20 feet. The Planning Commission may waive the request of curb and gutters for an internal private service road.
(4) Maintenance Agreement - The applicant proposing any internal service road intended to be owned and maintained as a private roadway shall record a maintenance agreement at the time of recordation of the access easement. The maintenance agreement shall delineate the parcels included within the maintenance agreement area and provide for the routine maintenance, repair and upkeep of the private roadway infrastructure and any associated facilities. The maintenance agreement shall run with the property and be wholly enforced upon subsequent property owners served by the internal service road. A copy of the maintenance agreement evidencing proof of recordation shall be submitted to the Zoning Administrator prior to any work commencing on the project.
