RE: Rainier View Estates – SUB-05-0531-YL
Third Review of Civil – Site Construction Documents
Mr. Foley:
The City of Yelm has completed the third review of the proposed Subdivision. Your application included:
Full Size Plans
11x17 utility Systems Plan
Response to 08-08-07 Comments from the City
Quiet Title Action
Storm Drainage Report
Water Well Decommission Report
We have reviewed the plans for compliance with the City of Yelm Development Guidelines, the DOE Stormwater Manual and general standards of civil engineering practice. The following
comments need to be addressed before the plans may be approved for construction. Our comments are summarized below:
Sewer Comments:
Vertical deflection is shown on the drawings for the 2” step mainline. Pipe deflection is not allowed.
The pipeline is show at greater than 7’ of depth. This is too deep. The elevation of the pipe should have 60” of cover.
Sta. 6+79, reference is made to “new End of Line Stationed between Clean-Out and Ball Valve cover.” Please clarify what this is referring too.
Reference is made to “Sewer Key Notes” at Sta. 6+79. What is this referring too?
No “Air release Assembly” is needed at Sta. 0+09.00.
Water Comments:
If the contractor is going to test against the existing gate valve at Sta. 0+00 if will be there responsibility to make sure it is in proper working order.
Water. On sheet C6, the utility crossing note # 3 calls out 8” Ductile Iron, should this read 8” PVC to be consistent with the plans or D.I. will need to be approved by the City of
Yelm Water Department and Engineering. (Drawing show’s 8” C-900 CL. 150 PVC.)
Landscape Comments:
Street trees on “non-sidewalk” side of street to be planted within the 5-foot planter strip directly behind curb, not on private property.
Clearly show access to the “Durant Street Path” from the development, pathway location and materials.
Display hydroseed within all planter strips and storm ponds.
Clean and reseed if needed the area between the “Durant Street Path” and the back perimeter fencing along the west property line. Please make this a note on the final landscape plans.
Irrigation Comments:
A complete irrigation plan needs to be submitted and approved prior to civil plan approval. See conditions of approval no 13.
Engineering Comments:
Locate street sign at the cul-de-sac indicating the future street connection location to the northwest. Please make this a note on the final landscape plans.
The cover of the construction plans notes a 17’ legal description gap that you are adding improvements too. You will be required to show ownership of this area prior to final plat approval.
The civil plans will be approved however this does not alleviate the responsibility of the owner to show ownership of this area. I was unable to verify this comment was complied with.
The planner was out of the office at the time of this letter. I will verify and if so please disregard.
Please review and revise the plans to address the above referenced comments. When the project is resubmitted you will need to submit 4 sets of plans, 2 stormwater reports. The project
engineer should include a written response with the resubmittal, indicating how all the review comments above have been addressed or responded to. This will significantly expedite our
review of the project. If you have any additional questions or comments please do not hesitate to call or contact me at jimg@ci.yelm.wa.us.
