RE: Civil Engineering Review No. 3
Prairie Business Park
Project No. SPR-02-8321-YL
Dear Mr. Nettleton:
I have reviewed the plans submitted and dated 06/02/03. The following are comments from the above referenced plans and need to be addressed on the future submittal.
The sanitary sewer system has been shown in plan view on the plans. I was unable to locate the keynotes calling out the sewer construction notes and engineering calculations. Please
submit the calculations showing that the 3,000-gallon step tank will serve this project. All information required to construct the utilities needs to be shown on the construction plans.
(As noted in the February 26, 2003 letter)
The water system as shown meets the requirements of the City of Yelm Development Guidelines and is approved as designed. If you choose the water main can be reduced to 8” in diameter.
8” is the minimum allowable size.
The fire hydrant callout needs to be revised to refer to an 8” hydrant. If you choose to retain the 10” waterline, than show how the hydrant will be connected to the 10” watermain.
The building is required to have fire hydrant coverage to all parts of the building. The maximum length of coverage from each fire hydrant is 150’. Currently the single fire hydrant
does not meet this requirement. (As noted in the February 26, 2003 letter)
The foundation design has been approved with the following revision. The minimum allowable frost cover is 18”. The plan shows 12”. Please revise.
Please review and revise your engineering drawings. When you resubmit your package, please send 4 revised sets and a letter addressing all the above referenced comments. If you have
any questions or comments, please call me at (360) 458-8438 and I will be happy to further assist you.
Respectfully
City of Yelm Community Development
