Wentworth Park Phase II has received P&Z approval. Wentworth Park Phase II is going to be a 9 unit office development similar to the Wentworth Park Phase L The main difference is that based on changes in zoning,Wentworth Park Phase II can be sold for medical office use in addition to regular office use. • As part of Jeff Doolittle's comments on the project was one pertaining to the anticipated flows from the project,and the adequacy in regards to installing the 8"sewer pipe at 0.5%slope. Based on our analysis,in order for the 8"pipe to have sufficient flow(self cleansing velocity of 2.5"/sec)at least once per day,the pipe would need to have an instantaneous flow of 0.175 CFS (see attached Manning pipe calculator sheet). This is equivalent to 1.3 gallons/sec. The peak discharge from a typical water closet(toilet)is approximately 1.3 gallons/sec. With 9 units,there : is a high likelihood that during a period when one toilet is flushed, additional water usage from sinks,etc.would be occurring in other unit(s).As such,we do not anticipate any issues with the adequacy of the 8"pipe at 0.5%slope. : Assuming that the above adequately addresses any issues with the 8"pipe,we will revise the plans to address the comment regarding the layout of the sanitary laterals into the first manhole. We are anticipating combining the two laterals from the north building into a single lateral into the manhole similar to the design for the western building. If you have any questions,please feel free to call. Sincerely, • / ,Y' a'a Galen Semprebon,P.E. Executive Vice President : Enclosures: : CC: Jeff Sawyer
