In a subsequent zoning process, staff will request that the area proposed for annexation be assigned the Suburban Residential (R-2) zoning district.  Utility service for the properties is provided by the Nolensville/College Grove Utility District (water) and Metro Water Services (sewer). The project will not impact the City's water/sewer infrastructure. 

The proposed non-binding R-2 plan for the property shows 19 total lots with an overall density of 0.67 units per acre.  This plan is consistent with the requirements of the Brentwood Municipal Zoning Ordinance. Note that the proposed internal roadway right-of-way will need to be adjusted to Collector Street standards since Sam Donald Road is an Arterial Street on the Major Thoroughfare Plan. Streets that feed into Arterials need to be designed to Collector Street standards.  The plan shows two proposed stub-streets -- one to the east and one to the west -- which will allow for appropriate future connectivity.  The property is currently zoned Municipal Growth Area 1 (MGA-1) by Williamson County. The tract can be developed under the existing zoning classification in the County.  The district standards require a minimum lot area of one acre and a gross density of one dwelling unit per acre. However, there are differences in the technical standards related to accessory uses and structure standards. MGA-1 allows the following:

1. Accessory dwelling units within an existing dwelling unit (interior apartment) or as a separate structure -- converted garage, carriage house or stable;
2. Only one accessory dwelling unit, regardless of the number of principal dwellings located on a single parcel are permitted;
3. Accessory dwellings shall be limited to 750 sq. ft. or 25% of the square footage of the principal structure, whichever is greater. In no case shall the accessory dwelling be more that 75% of the square footage of the principal dwelling; and 
4. Interior apartments may be contained within the existing house or attached onto the exterior. They must be constructed so that the exterior appearance of the home is maintained. A second front door is not permitted.

Staff notes that there is an existing access easement that runs along the western side of the property that serves two existing properties to the south.  Staff has discussed this with the applicant and indicated the need for that easement to be placed in common open space in any future subdivision and for a new easement to be created that will serve the easternmost lot to the south.  The applicant has agreed.  The new easement (in common open space) will allow the lot on the east to access the new cul-de-sac.  The other lot to the west will continue to use the existing easement on a more limited basis, as it will also tie into the cul-de-sac.  The non-binding plan provides a right-of-way dedication along Sam Donald Road for the future realignment of that road when the intersection of Split Log Road and Sam Donald Road is completed in the future.  The applicant has obtained an updated Sewer Availability Letter from Metro Water and Sewer and an availability letter from Nolensville/College Grove for water.
