*In 2007, the property received a variance approval that allowed a maximum of 25,796 ft2 of disturbance. (Case BA-06-12)
Background
The property currently contains an abandoned rock cut and building pad that started construction in 2007.
New Single Family Residence

Pool
Pools are proposed at the east and west ends of the residence.
Materials
No proposed material details have been provided at this point.
Landscaping
No proposed landscaping details have been provided at this point.
Land Disturbance
The building pad slope of 56% allows a disturbance of 8.4% of the lot but the property has an approved variance that allows up to 25,796 ft2 of area to be disturbed and a maximum driveway slope of 30%. The applicant has proposed a net disturbance of approximately 17% (25,796 ft2).
Grading and Drainage
There will be grading associated with the construction of the property in order to properly retain the “pre vs post” storm water volumes for the 100-year, 2-hour rainfall event.
Sewer
A new sanitary sewer system has previously been proposed for the property.

C. A recent aerial photo of the site (less than 1 year old), with topography, lot lines, and the building footprint superimposed on it, and identification of significant natural features as well as adjacent lots and structures within 100 feet of the perimeter of the subject property (min. 24”X 36”), and the location of the driveway access in relation to the nearest roadway.
