Re: Today’s Dental - City of Yelm Project Number - SPR-07-0135-YL
Review No.2 Site Construction Documents
Mr. Goroch:
The City of Yelm has completed the second review of Today’s Dental. Your application included:
Original sets of red-lined plans
Revised sets of plans
Revised final landscape plans were not included
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:
Step Sewer:
Sheet Note # 17 on sheet # C11.01 indicates that the existing STEP Tank behind to existing house is to be demolished. This tank along with all equipment within the tank (pump etc) belongs
to the City of Yelm and must be removed and delivered to the Sewer Department. The contractor will bare all costs associated with this including removal and disposal of septage from
within the tank.
Sheet # C31.01 shows the existing STEP Tank that serves the existing Dental Office being demolished. This tank is in use by the adjoining business as well and provisions need to be made
for disposal of sewage from this business if this tank is removed.
Sheet # C14.01 shows separate service lines leaving the new 8000 gallon STEP Tank. This should show only one 2” service line. Please see development guidelines.
The existing STEP Tank at Today’s dental is not H-20 Load bearing rated and must be protected. No parking over this tank.
Pump Control Panels for these 2 tanks need to be either mounted on a building or a remote post. If a remote post is used, the material must be “unistrut’
Hose bibs must be installed within 50’ of the pump end of each tank.
Submittals must be received and approved by the City of Yelm Sewer Department for this new tank.
The method of taping the existing Sewer main must be outlined.
Please show the Depth of Bury for this new tank.
Water:
The developer is responsible for the cost of the fire hydrant locks and the City of Yelm Water Department will order and install them. The project will not be final until the City of
Yelm has received the payment in full for the fire hydrant locks.
The irrigation service line from Yelm Ave doesn’t exist or domestic.
The water meter for the existing building is at the fence of Ichiban Teriyaki property line and dentist property.
They should install an irrigation service line along with the Domestic service line or use one of the two existing water meters for the irrigation system. This will require a backflow
assembly behind this meter.
The fire hydrant runs need to be hot tapped, not cut in Tee’s. See NOTE three of page C 24.01.
On both fire hydrant runs, they should use field lock gaskets and mega lug for thrust or put an ecology block behind the fire hydrants.
The service line to the domestic meter should be a 1 1/2 inch, not 1 ¼ inch service line.
All water line crossing the sewer mains will be required to have a 20 foot sleeve on them or 18 inches of separation.
Comment Response # 38 refers to a water note on sheet C03.01. I did not find this sheet, please clarify or add the sheet to plans.
The existing and proposed 6” waterlines should be C-900 pipe not 6” Ductile Iron.
Landscape and Irrigation:
Revised final landscape plans were not included
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 steveh@ci.yelm.wa.us.
