Grading shall not produce large, flat planes or sharp angles or intersection with the natural terrain. Slope catch points shall be rounded to blend with existing terrain.

No grading shall be commenced until the tentative map or tentative parcel map has been approved, a tree protection plan has been approved, a grading plan has been approved and a grading permit is issued. Issuance of building permits or release of security for improvement agreements may be conditioned upon receipt of approved written assurance by a registered civil engineer that the lot grading and building pad elevations have been done in conformance with the approved plan and/or geotechnical requirements.

D. No fill slopes proposed shall be steeper than two horizontal to one vertical, unless otherwise approved by the City Engineer.

E. No cut or fill slopes shall encroach on any street right-of-way within the subdivision, except where the City Engineer determines that topographical conditions warrant such slopes to be in rights-of-way and said slopes are approved by the City Engineer.

F. When it is determined by the City Engineer that the actual or proposed grading for the subdivision will create a nuisance or hazard to other properties, public ways or public facilities due to erosion from stormwater or rainfall, no grading shall commence or continue without specific consent in writing from the City Engineer.

G. Retaining walls shall be constructed where slopes within heretofore designated limits are exceeded and when said walls are required by the City Engineer. Said walls shall be constructed according to plans prepared by a registered Civil Engineer and approved by the City Engineer.
