Whenever the surface of a lot or plot is excavated, filled, graded or hard-surfaced with impervious material, positive drainage shall be provided so that a nuisance will not be created. Catch basins properly connected to storm sewers or other approved provisions, such as under-drains, shall be made where water may pocket, to preclude the accumulation of surface water. Surface water shall not be drained onto adjacent properties not in the same ownership without written permission from the owner of the adjacent property, and existing natural ground drainage of the ground area surrounding the lot or plot excavated, filled or graded shall not be impeded. (Ord. 64-24. Passed 3-2-64.)
