Proposed slope embankments along adjoining property lines and street frontages shall have a slope not steeper than one foot on three feet (33 1/3%) unless an adequate stabilization or retaining wall is provided as approved by the Planning Board or the Building Inspector. All slopes shall be adequately stabilized with topsoil and seeding or other approved planting with appropriate ground cover as approved by the Building Inspector.
The finished grade at a point not less than 10 feet from the building shall be set so as to be pitched away from the top of the nearest foundation at least 12 inches in 10 feet, except that the finished grade shall be no less than 10 inches lower than the top of the nearest foundation at a point no less than 10 feet opposite open porches, patios and pedestrian ramps.

All finished grades within 10 feet of the building shall pitch away from the building at a grade rate of not less than 10%.

All applications for a building permit and a certificate of oc-cupancy for a subdivision, business or commercial development shall be referred to the Planning Board for its review and approval pursuant to this chapter.
