(f)

Construction and work such as walkways, driveways, landscaping or any structure shall be installed so that the construction of same will not interfere with drainage. All sidewalks, driveways, patios and other flat work shall be at an elevation relative to the foundation wall so that water will drain away from the structure on all sides and off the lot in a manner which will provide reasonable freedom from erosion and permanently pocketed surface water.

(g)

The flow from off-site tributary areas that are tributary to an intermittent stream or overflow route that must pass through the parcel must be identified on the grading plan and must be designed in such a way to adequately convey the flow of all surface water for a 100-year storm frequency without damage to adjoining structures.

(h)

All overflow routes for the 100-year storm and for accumulated stormwater runoff from several lots or from off-site catchment areas must be clearly designated on the grading plan with the total width of the flow route contained within an easement for drainage purposes.

Ord. No. 08-50, § 2(exh. A(16.10)), 8-12-2008)
