Topic:  #PP02-S-12 Preliminary Plat,  The Reserve at Glanaman

Topic Description:

The applicant is seeking Preliminary Plat approval to divide approximately 47.56 acres into twenty-three (23) single-family residential lots ranging in size from ± 1.00 to 9.15 acres.  The property is zoned Residential (R-1) and is located on the north side of Airlie Road (Route 605), east of its intersection with Sundance Drive, in the Scott Magisterial District. 

The applicant has a companion Special Exception application requesting a waiver of the public water requirement and to permit a community water system.  The Board of Supervisors previously approved a Special Exception to permit the construction of a street in the floodplain.  A request to develop the subdivision on private streets has been withdrawn from consideration.  

Section 9-7 of the Subdivision Ordinance requires that "…all preliminary plats approved by the Planning Commission shall be referred to the Board of Supervisors at its next regularly scheduled meeting…If the Board takes no action on the preliminary plat referral, the preliminary plat shall be deemed approved in accordance with the actions of the Planning Commission."

The Planning Commission staff reports are available upon request.

Requested Action of the Board of Supervisors:

No action is necessary, unless a majority of the Board wishes to consider this preliminary subdivision application, and if the companion Special Exception request for a community water system is approved.  On June 26, 2003 , the Planning Commission voted to approve the Reserve at Glanaman Preliminary Plat, subject to the conditions noted below. 

1.            The Final Plat shall be in general conformance with the Preliminary Subdivision Plat entitled "The Reserve at Glanaman" dated June 9, 2003 and received in the Planning Office on June 9, 2003 . 

2.            Prior to Final Plat and Final Construction Plan approval, the applicant shall submit a detailed landscape plan as required pursuant to Section 7-600 of the Zoning Ordinance for review.

3.            All road design and construction shall be in accordance with VDOT’s Subdivision Street Requirements, Road and Bridge Standards, and Drainage Manual.

4.            At the time the streets are accepted into the Secondary System of State Highways for maintenance, a permit application, as-built plans and continuous bond will need to be provided by whomever is maintaining the private waterline to cover the waterline within the right-of-way.

5.            The sight distance profile shall indicate the design speed or posted speed used to calculate the sight distance.

6.            Details for the entrance on Route 29 that is to be used for the emergency access shall be provided to ensure the entrance is sufficient to accommodate emergency vehicles.

8.            The right-of-way width on Nicole Way shall transition at a defined point rather than the gradual narrowing.

9.            It appears that the easement for the waterline is being shown crossing the right-of-way, but there cannot be any easements within the proposed right-of-way dedication.

10.        If any work outside of the proposed road construction is to be conducted prior to house construction (overlot grading, cut and fill on individual lots, stockpiles, borrow areas, etc.), these areas shall be included in the E&S plan on the final construction plans.

11.        All intermittent streams shall be protected during construction.

12.        Sediment traps shall be used only for areas with less than three (3) acres of total drainage. 

13.        Sediment basins with drainage areas over twenty (20) acres shall be sized using the TR-55 method.

14.        Disturbance of cover on steep slopes shall be avoided, if at all possible.  Where needed, soil stabilization matting shall be used.

15.        Clearing and grading shall be limited to those areas needed to accommodate the proposed roads and infrastructure as indicated on Sheet 10 of the Preliminary Plat.

16.        Approval of over-lot grading plans and lot-specific erosion and sediment control plans shall be reviewed for approval prior to the receipt of the final building permits.

17.        All State and Federal permitting requirements shall be met prior to Final Construction Plan approval.

18.        A final floodplain study and dam construction plan shall be submitted for review prior to Final Construction Plan approval.

19.        The Applicant shall obtain a CLOMR/LOMR from FEMA prior to Final Construction Plan approval.
