A. 
For any of the activities regulated by this chapter, the final approval of subdivision and/or land development plans, the issuance of any building or occupancy permit, or the commencement of any land disturbance activity may not proceed until the property owner or developer or his/her agent has received written approval of a drainage plan from the Borough of Waynesboro.

The drainage plan shall be designed and certified by a professional engineer (P.E.), registered in the Commonwealth of Pennsylvania to perform such duties.
[Amended 3-19-2008 by Ord. No. 1071]
A. 
Exemptions are as follows:
(1) 
Any regulated activity that would create 2,500 square feet or less of impervious area is exempt from the provisions of this chapter. This criteria shall apply to the total development (entire parent tract) even if the development is to take place in phases. The date of adoption of this chapter shall be the point from which to consider tracts as parent tracts for which impervious area shall be inclusively considered. The developer shall be responsible to ensure that exempted activities shall maintain sound building and construction practices such that the quantity, velocity and direction of the resulting stormwater runoff will adequately protect health, safety, or other property from possible injury.
[Amended 3-19-2008 by Ord. No. 1071]
(2) 
Land disturbance associated with existing one- and two-family dwellings, subject to conditions described in Subsection A(1) of this section.

Notification of developer.
(1) 
For activities regulated by this chapter, the Borough of Waynesboro shall notify the developer, in writing, within 90 calendar days after official submission, whether the drainage plan is consistent with this chapter. Should the drainage plan be determined to be consistent with this chapter, the Director of Engineering will forward an approval letter to the developer.

H. 
The developer shall be responsible for completing an as-built survey of all stormwater management facilities included in the approved drainage plan. The as-built survey and an explanation of any discrepancies with the design plan shall be submitted to the Director of Engineering of the Borough of Waynesboro for final approval.

Time period for completion of construction.
(1) 
After the approval by the Borough Council of the Borough of Waynesboro of a drainage plan the developer shall have a period of three years to complete construction of the stormwater management facilities as shown on the approved drainage plan. This three-year time period shall commence on the date that the Borough Council of the Borough of Waynesboro approved the drainage plan. If stormwater management facilities included in the approved drainage plan have not been constructed, or if an as-built survey of these facilities has not been approved within this three-year time period, then the Borough of Waynesboro may consider the drainage plan disapproved and may revoke any and all permits. Drainage plans that are considered disapproved by the Borough Council of the Borough of Waynesboro shall be resubmitted in accordance with § 238-17 of this chapter.

If stormwater management facilities included in the approved drainage plan have not been constructed, or if an as-built survey of the facilities has not been approved within this additional three-year period, then the Borough of Waynesboro may consider the drainage plan disapproved and may revoke any and all permits. Drainage plans that are considered disapproved by the Borough Council of the Borough of Waynesboro shall be resubmitted in accordance with § 238-17 of this chapter.

A modification to a submitted drainage plan for a development site that involves a change in stormwater management facilities or techniques, or that involves the relocation or redesign of stormwater management facilities, or that is necessary because soil or other conditions are not as stated on the drainage plan (as determined by the Director of Engineering), shall require a resubmission of the modified drainage plan consistent with § 238-4 of this chapter and be subject to review as specified in § 238-5 of this chapter.
B. 
A modification to an already approved or disapproved drainage plan shall be submitted to the Director of Engineering of the Borough of Waynesboro, accompanied by the applicable review fee. A modification to a drainage plan for which a formal action has not been taken by the Director of Engineering of the Borough of Waynesboro shall be submitted to the Director of Engineering Borough of Waynesboro, accompanied by the applicable review fee.
