RE: Van Norhop Estates – File No. SUB-00-8262-YL
Review No. 2 of Civil Engineering Plans
Dear Mr. Knowles:
Thank you for your June 4, 2001 letter. I have reviewed your letter addressing the comments on this project. As you know the City of Yelm has hired a staff engineer. I will be reviewing
all current and future projects. I will not do a complete re-review of projects already in review however I will do a cursory review. The following comments need to be addressed before
approval of the plans.
General Conditions of Project Approval:
After discussions with Tim Peterson and Cathie Carlson, The City of Yelm would like to vacate the additional 11.5 feet of public right-of-way. Please be advised the location of the
underground utilities may be located in the right-of-way dedicated to your client.
Sheet C4:
The water system construction note no. 8 needs to be revised since the 10” water main has been added in Mill Road S.E. Please remove the reference to 8” size.
Sheet C7:
Please revise the STEP double service detail by adding the redlined comments on the plans.
Storm Drainage:
After discussions with PSE, we would like to have conduit placed at the utility trench crossings of the storm drainage infiltration trenches. This will keep the storm water facilities
from being disturbed during utility trench installation. Please show these on the plan and profile. Coordinate with the trench utilities for the sizes and number of crossings.
Remove the “public” reference to storm drainage on page 1 of the Storm Drainage Report.
Please provide stormwater quality calculations for the improvements in Mill Road SE. If the type 1 catchbasin does not provide the required volume for pretreatment a water quality vault
may be required. As the DOE manual recommends, the water quality facility should also be located “off-line.”
Please return the redlined drawings with your next submittal. If you have any questions please call me at (360) 458-8438 and I will be happy to further assist you.
Respectfully,
City of Yelm Community Development

Development Review Engineer
