Civil Engineering Plan Review No. 1
Dear Mr. Springer:
I have reviewed the plans and have the following questions and comments. Please review these comments and address them when you submit your final civil engineering plans for review.
These comments are from your land use application. You are still required to submit plans for civil engineering review prior to be able to construct this project.
All plans, reports and calculations need to have a current stamp and signature from a civil engineer registered in the State of Washington.
All information needed by the contractor to construct these improvements needs to be shown on the civil engineering plans. (i.e. trench sections, vault sections, plan views of all pipe
connections, test pit locations, electrical connection etc.) Please add the additional information to the plans.
Please review section 3-3.6.5 of the 1992 DOE Stormwater manual. This will outline the requirements for soils investigation. Additional information will be required based on the manual.
The soils investigation needs to be stamped by the civil engineer or the soils specialist who performed the testing.
The infiltration gallery bottom is required to be 36” above the highwater table. The report says that the highwater table is 72” below grade. Please revise the design to meet this
requirement.
The infiltration gallery is required to infiltrate the 100-year design storm. The calculations appear to use the 10-year design storm. Please clarify or revise the plans as required.
Please show where the roof drains are located, how they are being connected and where they are being connected to the conveyance system.
The oil water separator specified on the plan is actually a grease interceptor. Please specify another model and type of oil water separator for this project.
If the oil water separator is not rated for truck loading than place bollards around the vault and add a detail to the plans.
All pump wiring shall be Class 1, Div 1, intrinsically safe electrical components and assembly. Please add this note to the plans.
If you have any questions, please do not hesitate to call me at the Community Development Department at (360) 458-8438.
Sincerely,
Jim Gibson
Development Review Engineer
