RE: Civil Engineering Review No. 2
Prairie Business Park
Project No. SPR-02-8321-YL
Dear Mr. Nettleton:
I have reviewed the plans submitted and dated 01/17/03. The following are comments from the above referenced plans and need to be addressed on the future submittal. I have organized
these comments by sheet number.
Sheet 1 of 4
The manual requires test pits to be excavated in the location of the infiltration facility. The test pits are not located in the infiltration facility however they will be allowed.
The engineer will have to verify soil conditions during the construction of the gallery.
Sheet 2 of 4
The construction entrance has been removed from the plans. A construction entrance may be required if deemed necessary by the city inspector.
Sheet 3 of 4
Please verify the locations of the referenced details. There are many callouts for details referenced on sheet 5. Sheet 5 was not included in the plan set.
The observation wells will require H-20 load rated covers to be located in the parking area. I was unable to locate the detail addressing this comment.
The sanitary sewer system needs to be designed and shown on the plans. See the development guidelines for the requirements. Include the calculations, details, locations and connections.
The Technical Specifications you submitted are out of date. Refer to the Development Guidelines dated July 1999. All information required to construct the utilities needs to be shown
on the construction plans.
The water system needs to be called out in detail. Show all pertinent City of Yelm water details on the construction documents.
The water main system needs to be constructed of PVC. The City of Yelm does not utilize DIP. Please revise the callouts for the 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.
Sheet 4 of 4
Using the extended foundation as part of the bioswale design has been approved in the past. However you will be required to submit the foundation design now to gain civil engineering
approval to construct the bioswale. The foundation design that was submitted does not address the extended footing for this design. Please resubmit the required information addressing
the extended footing.
Redline Drawings:
Please see redline drawings for clarifications of the above comments. Their may be additional comments on the redline drawings not addressed by the above text.
The City of Yelm is researching the previous land use decisions for this property. If there is any outstanding issues from those land uses, they may add additional comments and or requirements
to this project.
Please review and revise your engineering drawings. When you resubmit your package, please send 4 revised sets and two drainage reports. 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
