Climbers Run Nature Center Pond Maintenance Project - Site Plans and Specifications

This document set comprises the detailed site plans and engineering specifications for pond maintenance work at the Climbers Run Nature Center, a project administered by the Lancaster Conservancy in Pequea, Pennsylvania, located in Lancaster County. The project scope includes dredging the existing pond, repairing the pond berm and outlet structures, installing toe rock protection, constructing an emergency spillway, and stabilizing streambanks. The work also encompasses the installation of a timber boardwalk and timber dock (750 square feet maximum), though these components are designated for separate bidding. The project area encompasses approximately 8 acres within Martic Township, with the pond maintenance disturbance area specifically delineated on the grading and erosion and sediment control plans. Field surveys were completed on January 31, 2024, and the site encompasses multiple soil types including Manor, Newark, and Pequea silt loams. The project is subject to NPDES permit requirements and wetland protection measures, with a seasonal restriction on clearing activities from May 15 through August 15 due to Northern Long-Eared Bat habitat considerations. Sealed bids for the overall site improvements project were due May 19, 2026, at 10 a.m. through the PennBid portal, with bids remaining open for 60 days following opening.

The project is funded in part through a state grant administered by the Pennsylvania Department of Conservation and Natural Resources and is subject to Pennsylvania Prevailing Wage Act requirements. Bidders must submit a lump sum and unit price basis proposal along with bid security equal to 10 percent of the bid amount, workmen's compensation affidavit, Public Work Employment Verification Form, and non-collusion affidavit. The successful contractor will be required to provide performance and payment bonds equal to 100 percent of the contract price. The plans specifically identify that certain components—the wetland boardwalk and pond dock with associated erosion and sediment measures—are marked for site improvements bidding separately, while remaining work constitutes the pond maintenance contract. The Lancaster Conservancy reserves the right to reject any or all bids and waive any defects, errors, omissions, irregularities, or informalities in submitted bids.

12. PROJECT IS LOCATED IN THE OCTORARA FORMATION WHICH IS COMPOSED OF CARBONATE GEOLOGY AND CAN BE PRONE TO SINKHOLES AND OTHER CARBONATE GEOLOGY RISKS. THE LIMITED EARTHWORK NEEDED FOR POND MAINTENANCE AND TO STABILIZE THE STREAMBANK AND IMPROVE POND ACCESS IS NOT EXPECTED TO AFFECT OR INCREASE RISKS ASSOCIATED WITH KARST GEOLOGY. SHOULD A SINKHOLE DEVELOP IT WILL BE HANDLED PER GEOLOGIST

RECOMMENDATION.

13. THERMAL IMPACTS ARE AVOIDED BY MAINTAINING NATURAL SITE DRAINAGE. THE POND IS SPRING FED AND CURRENTLY DISCHARGES TO THE STREAM. DURING THE PROPOSED POND IMPROVEMENTS, POND WATER WILL CONTINUE TO DISCHARGE TO STREAM THROUGH PUMPING AND FILTERING AS SHOWN ON PAGE 47 OF THE REVISED PLAN SET. THE STREAM WILL ALSO USE A PUMP AROUND FOR THE INSTALLATION OF THE ROCK TOE PROTECTION, RIP RAP APRON, AND LOWER PORTION OF THE EMERGENCY SPILLWAY. THERE SHOULD NOT BE LONG OR SHORT TERM THERMAL IMPACTS FROM THE PROPOSED WORK.

14. NO UTILITIES ARE KNOWN TO EXIST WITHIN OR CLOSE PROXIMITY TO THE LIMITS OF EXCAVATION FOR THE WORK SHOWN ON

THE PLANS.

15. APPROXIMATE UTILITY AND EASEMENT INFORMATION HAS BEEN PROVIDED BY THE UTILITY OWNER THROUGH THE PA 1-CALL DESIGN PROTOCOLS. THIS SURVEY/BASEMAPPING HAS BEEN PROVIDED WITHOUT THE BENEFIT OF A PROPERTY TITLE SEARCH, AND THEREFORE DOES NOT GUARANTEE OR IMPLY THE PROPERTY IS NOT AFFECTED BY EASEMENTS, RIGHTS-OF-WAY OR OTHER RESTRICTIONS. IT SHALL BE THE CONTRACTOR'S RESPONSIBILITY TO FIELD LOCATE ALL UTILITIES AND COORDINATE APPROPRIATE RELOCATION EFFORTS WITH THE RESPECTIVE UTILITY COMPANIES.

16. IT SHALL BE THE CONTRACTOR'S RESPONSIBILITY TO FIELD LOCATE ALL UTILTIIES AND COORDINATE APPROPRIATE

RELOCATION EFFORTS WITH THE RESPECTIVE UTILITY COMPANIES.

17. FLUVIAL SYSTEMS ARE DYNAMIC AND CHANGE OVER TIME. THE EXISTING CONDITIONS TYPOGRAPHY REPRESENTS THE CONDITIONS AT THE TIME OF THE FIELD SURVEY. DESIGN MODIFICATIONS MAY BE NECESSARY TO ACCOMMODATE CHANGES IN THE SITE CONDITIONS AT THE TIME OF CONSTRUCTION. LANDSTUDIES SHALL BE CONSULTED TO VERIFY THE EXISTING SITE CONDITIONS AND IDENTIFY CONSTRUCTION MODIFICATIONS THAT MAY BE NECESSARY BASED ON THOSE CONDITIONS.

18. A WETLAND DELINEATION ON THE SITE, INCLUDING A FIELD INVESTIGATION ON NOVEMBER 4, 2020, FEBRUARY 21, 2023. THE RESULTS OF THE INVESTIGATION INDICATE THE PRESENCE OF ONE WETLAND. EXISTING WETLAND BOUNDARIES ARE SHOWN

ON THE PLANS AND BASED ON A FIELD SURVEY PERFORMED BY CS DAVIDSON.

PER THE REQUIREMENTS OF CHAPTER 102 OF THE ADMINISTRATIVE CODES OF TITLE 25 (PA DEP RULES AND REGULATIONS), A COPY OF THE PROJECT SITE'S EROSION AND SEDIMENT POLLUTION CONTROL PLAN AND ITS ACCOMPANYING NARRATIVE MUST BE AVAILABLE ON-SITE DURING CONSTRUCTION UNTIL THE SITE HAS BEEN PERMANENTLY STABILIZED AND FOLLOWING

VERIFICATION FROM THE APPLICABLE REGULATORY AUTHORITY.

19. THE PENNSYLVANIA NATURAL DIVERSITY INVENTORY (PNDI) SEARCH RECEIPT SHOWS THE LIMITS OF DISTURBANCE WITHIN THE VICINITY OF THE NORTHERN LONG-EARED BAT. NO CLEARING ACTIVITIES MAY TAKE PLACE WITHIN THE SEASON

RESTRICTION FROM MAY 15 - AUGUST 15.
