RE: Discovery Counseling – SPR-04-0200-YL
Review of Engineering Construction Documents
Mr. Bromberg:
The City of Yelm has completed the initial review of the proposed Discovery Counseling Center. Your application included:
Engineering Plans dated June 20, 2005
Civil Plan Review Application
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:
Cover Sheet (sheet 1 of 6):
Add the surveyors name to the cover sheet. Also add the basis of bearings, vertical datum and horizontal datum to all sheets.
This project will be served by Ycomm Networks for Communications.
Street and Utility Site Plan (sheet 2 of 6):
The backflow device should be a Double Check Valve instead of the proposed pressure reducing backflow prevention valve.
The water meter and DCV will need to have H-20 load bearing boxes and covers.
Street Details (sheet 3 of 6):
Detail F D1-2 needs to show the CSTC and ballast being extended to the centerline of the roadway.
Detail G D1-2, the ballast in not required by the city under the alley and the paving section should be 2” in thickness.
Detail E D1-2 should be 16’ in width
Utility Details (sheet 4 of 6):
The Double Check Valve assembly detail on sheet 4 of 6 needs to be replaced with the approved City of Yelm detail.
Stormwater and Grading Plan (sheet 5 of 6):
Show how the storm water is going to be treated and contained on 2nd Ave.
Revise the curb bulb out to meet the dimensions shown in City of Yelm detail no. 4-8B. Also add the detail to the plan.
The city agreed to defer the sidewalk installation for this proposal. However the area that the sidewalk was expected to be installed in needs to remain unused so the sidewalk may be
installed in the future.
The onsite stormwater design needs more information. It appears that the storm water is being directed to the alley entrance. This project must contain all runoff on site and not direct
it to the adjacent properties.
The frontage improvements need more detail to be constructed. Please add additional vertical elevations to the design.
Please provide engineering calculations showing the stormwater system will be adequate to infiltrate the stormwater.
Landscape Plan:
Street trees and planter strips are deferred as part of the road frontage deferral. Grass shall be planted behind curb in that area.
Add one deciduous tree in the planter strip between the alley and the parking stall adjacent to the alley. (See attached plan)
Conditions of Approval: (How and when they are to be met)
TFC charge will be paid at engineering approval.
Will be addressed by engineering documents.
No water and sewer calculations are required at this time.
Will be addressed by engineering documents.
Will be addressed by engineering documents
Will be addressed by engineering documents
It has been expressed that the applicant is going to use a residential garbage can
This has been addressed.
Will be addressed with the engineering design approval.
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 is required to 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.
