Applications for each building permit shall be accompanied by a grading deposit.
(a) This deposit shall be used for the verification of finished ground grades to confirm if they conform to the approved grading plan. If necessary, the deposit can be used to grade the site in accordance with approved grading plans. Costs for inspection shall be calculated at a rate of not to exceed fifty dollars ($50.00) per hour.
(b) The developer or builder shall grade in order to establish street, blocks and lot grades in proper relation to each other, as follows:
(1) Streets. Grading of streets shall extend the full width of the right of way. Tree lawns shall be graded at a gradient and prescribed in the City standard details upward from the curb to the right-of-way line whenever possible.
(2) Blocks. Grading shall be designed to divert water from structures, to prevent standing water and soil saturation detrimental to structures and the use of lots, and to preserve desirable site features and grades for safe and convenient access to and around structures.
(3) Lots. The floor elevation of each structure shall be established in proper relation to surrounding grades, driveways and streets. There shall be a minimum grade of five percent around each structure so that water drains to lower areas. Drainage swales shall have a minimum grade of 0.5 percent. Each lot shall have access to a rear yard inlet basin. Lot grading shall be designed so that surface water will drain into the driveway, a drainage structure on the lot, a street gutter and storm sewer or a natural drainage way. Minimum and maximum grades of driveways shall be 0.5 percent and 10.0 percent, respectively. Grade breaks must be no greater than fifteen percent. Grading shall be adjusted so there will be no abrupt grades in front yards and along side lot lines. Earth terraces shall have a maximum side slope ratio of 2.5:1.
(4) Top Soil. If grading results in the stripping of top soil, such soil shall not be removed from any subdivision or used as fill, but shall be saved and uniformly spread over the lots as grading is finished.
