This chapter shall be known and may be cited as the ‘Township of Aston Erosion and Sedimentation Control Ordinance.’’ (Ord. 360. Passed 9-19-90.)
The purpose of this chapter is to regulate the modification of the natural terrain, the alteration of drainage, and the maintenance of artificial structures and surfaces within the Township of Aston so as to assure and safeguard the health, safety, morals, and general welfare of the citizens of the Township of Aston. (Ord. 360. Passed 9-19-90.)
