This design will allow parking at the back of curb on both sides of the street or possible bike lanes to be added in the future. 4. Is advance grading variance being requested to grade the lots with construction of infrastructure and to advance grade future phases with the issuance of a grading permit for Phase 1? 5.

If disturbed area is 1 or more acres, obtain a NPDES storm water permit from the Arkansas Department of Environmental Quality prior to the start of construction. 8. Alteration of the water course will require approval from the Little Rock District of the US Army Corps of Engineers prior to start of work. 9.
