No person shall engage in earthmoving sufficiently close to the property line to endanger any adjoining public street, sidewalk, alley or other public or private property without supporting and protecting such public street, sidewalk, alley or other public or private property from settling, cracking or other damage which might result from such earthmoving. If, in the opinion of the Township Engineer, the nature of the earthmoving is such as to create a hazard to life or property unless adequately safeguarded, the applicant shall construct such walls, fences, guardrails or other structures to safeguard the public street, sidewalk, alley or other public property and persons using such, as the Township Engineer may require.
No person shall dump, move or place any soil, bedrock or other material or divert or increase the flow of water so as to cause the same to be deposited upon or roll, flow or wash upon or over the premises of another without the express consent of the owner of such premises so affected, or upon or over any public street, street improvement, road, sewer, storm drain, watercourse or right-of-way or any public property.[1]

If any soil, bedrock or other material or water or liquid is caused to be deposited upon or to roll, flow or wash upon any public property or right-of-way in violation of the above sections of this article, the person responsible shall be notified and shall cause the same to be removed from such public property or way within 36 hours. In the event of an immediate danger to the public health or safety, notice shall be given by the most expeditious means and the material or liquid shall be removed immediately. In the event that it is not so removed, the Township Engineer shall cause such removal and the cost of such removal shall be paid to the Township of Lower Merion by said person responsible and shall be a debt due the Township of Lower Merion. The Township Engineer shall submit a bill for all such costs to said person responsible. All such costs incurred by the Township shall be a personal obligation of said person responsible and shall be a lien upon the premises of such person, and whenever a bill therefor remains unpaid for a period of 60 days after it has been rendered by the Township Engineer, the Township Solicitor shall file a municipal claim or an action of assumpsit for such costs in the manner provided by law for the collection of debts and municipal claims.
