RE: ST05-01 Deforest Road Reconstruction
Thanks. I will redesign and see if my numbers work. I forgot to talk about the contract amendment. We
will need to discuss when you get a chance

Dan,
Due to the additional drainage area and time of concentration of 15 min, it is the City's position for storm
sewer Line B to have parallel 36" RCP from the end of concrete to approximately the upstream end of the
existing 36" RCP. Please take a look at the attached spreadsheet for my draft design and use it to come
up with your final design. This design will allow the 10 year storm event in the pipe with minimal overflow
during the 25, 50 and 100 year events. We have also reviewed that the HGL is still below the adjacent
finish floor elevations.
This design will provide adequate capacity within the project limits. This will also prevent removal of the
existing concrete, screen wall and damage to the pond bank. In the future, the capacity of the existing
downstream system can be increased. We will finish our review of the plans sometime next week.
Thank You,
George Marshall, P.E.
