Ambler Vale Subdivision (Lot 7): Preliminary Plat PPLT05-SC-022, Scott District


Topic Description:


The applicant is seeking Preliminary Plat approval to divide approximately 5.23 acres into two (2) single-family residential lots of ±3.31 and ±1.92 acres.  These two (2) divisions will exhaust all subdivision potential on the property.  Each property will be served by public water and septic drainfield systems.


Zoning/Acreage/Land Use:


The ±5.23-acre property is zoned Residential (R-1).  Adjacent properties are zoned Residential (R-1) and used for residential purposes.


Requested Action of the Board of Supervisors:


No action is necessary, unless a majority of the Board wishes to consider this preliminary subdivision application.  On July 28, 2005, the Planning Commission voted to approve Ambler Vale Subdivision (Lot 7) Preliminary Plat, subject to the conditions noted below:


  1. The Final Plat shall be in general conformance with the Preliminary Plat entitled "Ambler Vale Subdivision (Lot 7)" dated February 23, 2005, signed by Robert L. Sporles on June 7, 2005 and received in the Planning Office on June 10, 2005, except as modified by these conditions.  This approval is for a maximum of two (2) residential lots.


  1. The County recommends that no below grade basements be constructed on soils with high water table due to wetness unless the foundation drainage system of the structure is designed by a licensed professional engineer to assure a dry basement and preclude wet yards and recirculation of pumped or collected water. Unless, in the opinion of the


County Engineer, the topography of the lot in relation to the overlot-grading plan precludes grading the site to drain the basement to daylight, all basements shall be designed to gravity daylight without assistance from mechanical means. All discharged water (mechanical or gravity) must be conveyed to the subdivision stormwater collection system and discharged through the stormwater management facilities. Drainage easements, where necessary, shall be placed on the final plat. A note shall be placed on the final plat stating, “Basements are not recommended in mapping unit 16B.  A basement in this mapping unit is subject to flooding due to high seasonal water tables. Sump systems may run continuously, leading to possible premature pump failure.”


  1. Driveway culverts shall be designed to pass the 10-year storm.


  1. Access shall be provided to the well lot.


  1. The plan and plat shall reference that no access shall be allowed to Ambler Vale Drive (Private Street).


  1. Entrances shall be constructed in accordance with PE-1 standard with minimum 15” x 30’ culvert pipe.


  1. The house on Lot 7R shall be relocated outside of soil map unit 48B.


  1. Verification as to whether wetlands are present and acquisition of any necessary permits shall be required prior to final construction plan approval due to soils type 16B, which is characterized as having hydric inclusions.


  1. Map units 48B and 440C shall be added to the Interpretive Guide sections along with labeling the version used.  Use the most up-to-date version of the Interpretive Guide.




The property is located south of State Route 674 (Gray’s Mill Road) off Ambler Court in the Ambler Vale Subdivision, Scott Magisterial District.
