Forks Township is very concerned about water runoff. Developers are required to submit a grading plan for review by the township and must follow the plan before a c.o is issued. Initial grading does sometimes settle and some touch-up work is required and grass must be established before total stabilization occurs.
If you experience problems before all this happens, consult your builder to correct the problem. It is not permitted to intentionally discharge water onto a neighbor's property. Once a certificate of occupancy is issued by the township, any further soil disturbance is the sole responsibility of the homeowner. If any disturbance results in a dispute with neighboring properties, the matter must be handled by civil action between residents.
