RE: Yelm Senior Center Civil Engineering Review No. 1
City of Yelm Project No. CUP-03-8336-YL
Dear Mr. Merritt:
I have reviewed the plans received on January 12, 2004. The following are comments from the above referenced plans and need to be addressed on the future submittal. I have organized
these comments by page number. If a sheet number is not included, then there are no comments at this time for that sheet.
Sheet C0.1
The approval block should read Development Review Engineer. Typical all sheets
Sheet C1.1
Add Basis of Bearings to all sheets. Please do not reference another survey, put the description information on the plans.
Sheet C3.1
The maximum slope on the filter strip should be 5%
Please add the wheel stop detail to the plans.
The filter strip will need to have sod installed. The hydroseed will not have time to mature before stormwater is introduced to the system.
Show ADA ramps where required on the side plan or label where sidewalk is flush with asphalt.
Sheet C4.1
Remove the pig port and install an end of line cleanout at end of sewer line.
The step sewer system should be a duplex pumping system.
Sewer callout No. 2 should have one gate valve located on the west side of the tee. The valve on the north side is shown on the service detail and will be a ball valve only used for
testing the service line. It will be buried after testing. I did not want the contractor to think a gate valve was required at the north location.
What is the existing valve located at the entrance for?
Add the trench detail to the plans.
Min. cover over the step main in 60”
Show a hose bib within 50’ of the step tank.
Add the missing information for the step sewer connection to the bridge.
Sheet C4.2
Show duplex system details on the plan.
Sheet C 5.1
The asphalt section on the frontage should be 3” instead of 2”. The development guidelines are in error.
The driveway concrete approach should be 30’ instead of 26’.
Please review and revise your engineering drawings. When you resubmit your package, please send 4 revised sets. 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
Jim Gibson
Development Review Engineer
