PB 24 19 TheWayMaker LLC 40 Eagle Ridge Way Draft Resolution

5 10. The Applicant’s contractor, Paul Grabowski, testified that he cleaned out the drainage ditch, placed riprap and replaced 2-12” clay drainage pipes that were broken and blocked with debris with a 36” concrete elliptical pipe. 11. The Objector’s engineer, Mr. Keller, testified and provided exhibits as to what he characterized as a more direct and voluminous flow of water downhill into Llewellyn Park properties subsequent to the installation of the new 36” pipe. 12. Testimony from the Applicant’s Engineering Expert, Jesse Cokeley, P.E. established that the Applicant submitted a storm water management site plan that included a drainage plan. 13. Originally the project was believed to be a minor development and so Applicant installed a permitted dry well system to capture the required 3” of rainfall displacement created by the construction of the pool and pool house (and the outfall of the boulder wall.) 14. When it was determined by Township officials that the project was a major development, the requirements for stormwater management as per the DEP regulations and Township Ordinances required the system to include peak flow drainage for a 2-year, 10 year, and 100-year storm and ground water recharge. Therefore, a new underground system was designed and Applicant further proposed to replace the impervious driveway pavement with pervious pavers. 15. Engineering expert Cokeley testified that the stormwater management system submitted with the Application is designed to maintain 100% of the average recharge volume and that it meets or exceeds the required run-off for a 2-, 10- and 100-year storm.
