Land Disturbance
A net disturbed area of 49.50% (76,879 ft2) currently exists on the lot and the building pad slope of 22.20% allows a disturbance of 16.22% (25,168 ft2) the lot. The applicant has proposed a net disturbed area of approximately 49.50% (76,879 ft2), which matches the existing net disturbance.
Grading and Drainage
There will be grading associated with the construction in order to properly retain the “pre vs post” storm water volumes for the 100-year, 2-hour rainfall event. Stormwater generated onsite will be retained in underground pipes located within and along the driveway.
Sewer
The property has an existing connection to the City of Phoenix sewer system.
