Child proof trash racks or anti-vortex devices shall be constructed at all outlets and designed to facilitate cleaning and avoid clogging caused by debris.
(6) 
Stabilization. Prior stabilization, structures including stilling basins, energy dissipators, and channel lining shall be constructed at the outlets of all basins and emergency spillways. The stabilization structures shall control water to avoid erosion, reduce velocities of released water and direct water so that it does not interfere with downstream activities.
(7) 
Wet Basins. Existing ponds or permanent pool basins can be used provided that they meet the following criteria:
(a) 
The minimum permanent pool level shall be maintained to allow sufficient depth throughout the year to reduce the growth of unwanted vegetation and mosquitoes.
(b) 
The pond must be of sufficient size to allow the appropriate aquatic community needed to maintain a healthy pond ecology.
(c) 
An outlet structure shall be designed to allow complete drainage of the pond for maintenance.
(d) 
The applicant shall submit wet basin planting schedule and method for mosquito control.
The design of a detention facility with a permanent pool shall include the determination of the proposed site's ability to support a viable permanent pool. The design shall take into account for such factors as the required rate and quality of dry weather inflow, the quality of stormwater inflow, seasonal and longer term variations in groundwater table, and effects of suspected pollutant loadings.
(8) 
Basins with Gabion Dams. Gabion outlet control structures for stormwater basins shall be filled with rocks six inches to eight inches in diameter. Outlet flow through the gabions shall be calculated by the following equation:
Q = (0.40 x h x 2)/L
Where:
Q
=
Flow in cubic feet per second (CFS)
h
=
Height of ponding in basin (feet)
w
=
Width of stone structure (feet)
L
=
Average structure thickness (top of berm + bottom of berm)/2
(9) 
Underground Basins. Underground stormwater detention systems can be used where sufficient space is not available for above-ground systems or where underground storage systems are recharging groundwater.
(10) 
Developers are encouraged to use best management practices (BMPs), if appropriate, to provide for additional water quality improvement and groundwater recharge. The methods and design criteria of stormwater controls or BMPs that may be used are described in the Borough Stormwater Management Ordinance [Chapter 23], as amended, and the "Pennsylvania Stormwater Best Management Practices Manual," December 2006, as amended. In evaluating potential stormwater BMPs, the order of preference shall be as follows:
(a) 
Infiltration BMPs.
(b) 
Wet ponds.
(c) 
Artificial wetlands.
(d) 
Minimum first flush detention or dual purpose detention (where appropriate).
7. 
Design Submission.

The center line of all new streets shall be marked with spikes (P.K. nails) and referenced to permanent monuments or structures. Certified copies of this reference information shall be given to both the Borough Engineer and the Borough Office. When final lot grading has been completed and before the issuance of occupancy permits, permanent monuments shall be set by the subdivider, developer, or builder, at all lot corners and angle points, and at all street intersections and intermediate points as may be required.
2. 
Lot Pin Requirements. All lots upon which construction is planned shall be temporarily staked or pinned, or permanently monumented and certified to such by a registered surveyor for the owner, subdivider, builder, or developer, before issuance of a building permit. A signed certificate of compliance must be submitted with a building permit application. Temporary stakes or pins with a surveyor's ribbon attached may be acceptable on existing lots where construction of an accessory building or an addition to the primary structure is proposed, only if construction is begun within 30 days of the certificate of compliance date. Temporary stakes or pins shall remain in place until witnessed and accepted by the Borough Building Inspector. Prior to final approval of a new subdivision plan, all new lot corner markers shall be marked with a minimum 5/8 inch diameter metal pin extending at least 24 inches into the ground and at least one inch revealed above the ground surface, or an equivalent metal marker, approved by the Borough Engineer. Upon completion of construction and final grading, pins shall be replaced with permanent monuments as described in Subsection 1.
3. 
Original Monuments. In situations where they may be of legal or historical importance, the original monuments and marks must not be destroyed, defaced, hidden, or possible confused by creating new monuments and marks unless absolutely necessary, e.g., the originals are decayed, destroyed, or unsafe. In some cases, to be determined by the Borough Engineer, new monuments shall be set as a reference or witness to the original monument to avoid disturbing the original. When in the opinion of the Borough Engineer, the angle point falls in a location that is not appropriate to set a concrete monument, a written request for a waiver shall be submitted for consideration by Borough Council.
4. 
Bench Marks. The Borough elevations are based on the USGS datum. Location and elevation is available to all engineers and surveyors upon request to the Borough Engineer's Office. All contours and elevations shown on the plan must be based on this system.
