Grade lines.

[Amended 8-10-1978]A. In all residential districts the finished grade line of all lots at the foundation wall shall be 18 inches above the crown of the road.B. In the residential districts, in the event that the setback is reduced, the required grade line may be reduced proportionately.C. The Building Inspector is hereby granted authority to vary the above grade-line requirements depending upon the nature of the topography involved in all instances.

In the event that drainage problems are indicated, the Building Inspector, before the issuance of a building permit, may make specific requirements as to grading and drainage, including the installation of drainage tile, if required in his opinion.D.

The Planning Board may review, modify or change, upon application, the decision of the Building Inspector herein as to grading and drainage requirements.
