Prior to approval of the constructed stormwater management facilities of the approved drainage plan, the developer must provide a schedule of inspections along with a final inspection and submission of as-built drawings to the Township Engineer. These inspection provisions pertain only to construction activities regulated by the plan preparation provisions of Article IV. However, any activities granted exemption from plan preparation provisions as described in §§ 91-12 and 91-36 and therefore exemption from the inspection provisions must manage stormwater in the manner specified in the other provisions of this chapter.
A.
The developer must submit a certification by a Pennsylvania-registered professional engineer, which certifies that all elements of the approved drainage plan have been constructed as designed and approved.
B.
The Township Engineer or a designee shall inspect all phases of development of the site, including but not limited to:
(1)
Completion of preliminary site preparation, including stripping of vegetation, stockpiling of topsoil and construction of temporary stormwater management and erosion control facilities.
(2)
Completion of rough grading prior to placing topsoil, permanent drainage or other site development improvements and ground covers.
(3)
During construction and installation of the permanent stormwater facilities at such times to be specified by the Township Engineer.
(4)
Upon completion of permanent stormwater management facilities, including established ground covers and plantings.
(5)
Upon completion of any final grading, vegetative control measures or other site restoration work done in accordance with the approved drainage plan.
C.
No work shall begin on a subsequent stage until the preceding stage has been inspected and approved by the Township Engineer or the designee.
D.
It is the responsibility of the developer to notify the Township Engineer or the designee 48 hours in advance of the completion of each identified phase of development.
E.
In the event that the Township Engineer or designee discovers that the work does not comply with the approved drainage plan or any applicable laws and ordinances, the township shall stop work until connections are made. Any portion of the work that does not comply with the approved plan must be corrected by a developer within 30 days. No work may proceed on any subsequent phase of the drainage plan, the subdivision or land development or building construction until the required corrections have been made.
F.
If at any stage of the work the Township Engineer or the designee determines that the soil or other conditions are not as stated or shown in the approved drainage plan, he or she may refuse to approve further work and the township may revoke approvals until a revised drainage plan is submitted and approved, as required by § 91-16 of this chapter. If the revised drainage plan cannot remedy the situation, then the township reserves the right to cancel the township approval and to halt all work except for that work required to close-out the activity and return the site to preactivity conditions as much as is reasonably possible.
G.
If the Township Engineer or designee discovers that the facilities or measures installed may be in violation of Chapter 102, Erosion Control, of the Clean Streams Law[1] provision, the Engineer or designee will refer these violations to the appropriate Conservation District.

Editor's Note: See 35 P.S. § 691.1 et seq.
When the developer has completed all of the required facilities, he or she shall notify the township in writing by certified or registered mail and shall send a copy of such notice to the Township Engineer. The township shall, within 30 days after receipt of such notice, authorize the Township Engineer to inspect the required facilities. Following this final inspection, the Township Engineer shall promptly file a report, in writing, with the township and shall mail a copy of the report to the developer by certified or registered mail. The report shall be made and mailed within 30 days after receipt by the Township Engineer of the aforesaid authorization by the township.
Following final inspection, the developer shall submit drawings bearing the seal of a Pennsylvania-registered professional engineer indicating the as-built improvements called for in the approved plan.
