Subject: Paula Lane
I would like to take this 'opportunity to correct information that, was given at the last
City Council Meeting concerning the subject project. Rollin Bruce presented drainage
calculations to Craig Spaulding and.A1 Cornwell just prior to the meeting on work that we
performed for him three plus years
ago in conjunction with the development of his property. The calculation
package along with his subsequent'pres6ntation implied that we had also reviewed the
drainage calculations by CSW S.tuber- Stroeh, and were in disagreement with their findings.
Mr. Bruce took the posit _ion'that ,an, oversight 'by,CSW'Stuber' ='.S.troeh had occurred because
they had different runoff quantities at -one culvert compared'to our report while making it
appear that we were somehow in agreement with this assessment'.. To this date we have not
been asked by Mr. Bruce or any other party to review any work related to this project.
Hydrology and hydraulic calculations can be complicated at many levels from evaluating
drainage areas, runoff coeffidl ents, times of concentration, etc. and Mr. Bruce does not
have the professional expertise' to'make a qualified judgment in this area. I support Mr.
Bruce's right to say what he wants but not when he attempts to validate his position based
on our-professional experience and reputation when neither was sought.
Sincerely
Steven J. Lafranchi, P.E., P.,L.S..
