A. 
Before submitting the stormwater plan, applicants are urged to consult with the municipality on the applicable regulations and techniques for safely managing runoff from the development site. The municipality may also be helpful in providing necessary data for the stormwater management plan.
B. 
Applicants are encouraged to submit a sketch plan with a narrative description of the proposed stormwater management controls for general guidance and discussion with the municipality and other agencies.
C. 
The preapplication phase is not mandatory; any review comments provided by the municipality are advisory only and do not constitute any legally binding action on the part of the municipality.
A. 
Submission of plans. Stormwater plan applications shall be submitted with the preliminary and final subdivision/land development applications.
B. 
Notification of affected municipalities. The developer is required to notify municipalities immediately downstream of the development site that a stormwater control plan has been submitted. Copies of the plans will be made available to the municipalities upon request. Comments received from any affected municipality will be considered by the Municipal Engineer and county agencies in their reviews.
C. 
Municipal Engineer's review. The Municipal Engineer shall recommend approval or disapproval of the stormwater management plan based on the requirements of the municipal ordinances, the standards and criteria of the watershed plan and good engineering practice. The Engineer shall submit a written report, along with supporting documentation, stating his or her reasons for approval or disapproval.
D. 
Permits required from other governmental agencies. Where the proposed development requires an obstruction permit from the Pennsylvania DEP or an erosion/sedimentation permit from the County Conservation District, final stormwater management plan approval shall be granted subject to the receipt of such permits. No building permit shall be issued, nor construction started, until the permits are received and copies filed with the municipality.
A. 
Upon final stormwater plan approval, receipt of all necessary permits, and recording of the final subdivision or land development plan in the Beaver County Recorder of Deeds office, the applicant may commence to install or implement the approved stormwater management controls.
B. 
If site development or building construction does not begin within two years of the date of final approval of the stormwater management plan, then before doing so, the applicant shall resubmit the stormwater management plan to verify that no condition has changed within the watershed that would affect the feasibility or effectiveness of the previously approved stormwater management controls. Further, if for any reason development activities are suspended for two years or more, then the same requirement for resubmission of the stormwater management plan shall apply.
A. 
If the request for a plan modification is initiated before construction begins, the stormwater plan must be resubmitted and reviewed according to the procedures contained in this article.
B. 
If the request for a plan modification is initiated after construction is underway, the Municipal Engineer shall recommend approval or disapproval of the modification based on field inspection provided:
(1) 
The requested changes in stormwater controls do not result in any modifications to other approved municipal land use/development requirements (e.g., building setbacks, yards, etc.) and
(2) 
The performance standards in Article III of this chapter are met. Notification of the Engineer's action shall be sent to the governing body, which may issue a stay of the plan modification within 14 days and require the permittee to resubmit the plan modification for full stormwater plan review in accordance with the procedures contained in this article.
