B.              The agent may authorize the following subdivisions to be developed with one (1) or more new private streets or shared driveways; 

 

1.   A family subdivision.

 

2.   A two-lot subdivision if: (i) the division contains only two lots and the private street will serve only those lots and will be the sole and direct means of access to a public street; and (ii) it is located within the rural areas designated in the comprehensive plan.

 

3.  Subdivisions for attached housing developments and non-residential developments located in a development area designated in the comprehensive plan, where units or groups of units are to be located on individual lots.

 

 

Sec. 14-234  Procedure for authorization to construct private road street and related matters.

 

     A request for authorization to construct one or more private roads in a subdivision and for consideration of a related matter, as provided in sections 14-232 and 14-233, shall be submitted, processed and approved as provided herein:

 

     Requests under sections 14-232(A) or 14-232(B) shall be submitted, processed and acted upon as follows:

Sections out of proposed Subdivision Text Amendment related to

overlot grading plans in the Development Areas

 

 

Sec. 14-313 Overlot grading plan.

 

     Within a development area designated in the comprehensive plan, the subdivider shall submit, prior to or with the final plat, an overlot grading plan showing existing and proposed topographic features to be considered in the development of the proposed subdivision, and   satisfying the following:

 

     A.   The plan shall show all proposed streets, building sites, surface drainage, driveways, trails, and other features the agent determines are needed to verify that the plan satisfies the requirements of this section.

 

B.   The plan shall be drawn to a scale not greater than one (1) inch equals fifty (50) feet.

 

C.   All proposed grading shall be shown with contour intervals not greater than two (2) feet.  All concentrated surface drainage over lots shall be clearly shown with the proposed grading.  All proposed grading shall be shown to assure that surface drainage can provide adequate relief from flooding of dwellings in the event a storm sewer fails.

 

D.   Graded slopes on lots proposed to be planted with turf grasses (lawns) shall not exceed a gradient of three (3) feet of horizontal distance for each one (1) foot of vertical rise or fall (3:1).  Steeper slopes shall be vegetated with low maintenance vegetation as determined to be appropriate by the program authority in its approval of an erosion and sediment control plan for the land disturbing activity.  These steeper slopes shall not exceed a gradient of two (2) feet of horizontal distance for each one (1) foot of vertical rise or fall (2:1), unless the agent finds that the grading recommendations for steeper slopes have adequately addressed the impacts.

 

     E.   Surface drainage shall not flow across more than three (3) lots before being collected in a storm sewer or directed to a drainage way outside of the lots.  No surface drainage across a residential lot shall have more than one-half (1/2) acre of land draining to it.

 

     F.   All drainage from streets shall be carried across lots in a storm sewer to a point beyond the rear of the building site.

 

     G.   The plan shall demonstrate that driveways to lots will not be steeper than twenty (20) percent and shall include grading transitions at the street that the agent determines will allow passenger vehicles to avoid scraping the vehicle body on the driveway or the street.  Additionally, the driveway grading shall provide an area in front of the proposed garage, or an area proposed for vehicle parking where no garage is proposed, that is not less than eighteen (18) feet in length that will be graded no steeper than eight (8) percent..   

 

H.   The plan shall demonstrate that an area at least ten (10) feet in width, measured outward from the face of the structure, has grades no steeper than ten (10) percent adjacent to possible entrances to dwellings.  This graded area shall extend from entrances to driveways or walkways connecting the dwelling to the street.

 

     I.   Any requirement of this section may be waived by the agent as provided in section 14-224.1.  In reviewing a waiver request, the agent shall determine whether an alternative proposed by the subdivider satisfies the purpose of the requirement to be waived to at least an equivalent degree.
