RE: Ft. Stevens Elementary School Remodel and Play Shed – City of Yelm Project No. SPR-07-0156-YL Initial Review of Civil Construction Documents
Dear Trent:
The City of Yelm has completed the initial review of the proposed Ft. Stevens Elementary School Remodel and Play Shed. Your application included:
Construction Documents
Stormwater Report
Missing Landscape Plans
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 are from Community Development (Engineering), Water, Sewer and Public Works Departments only. You will need to submit Landscape Plans for review. The following comments need
to be addressed before the plans may be approved for construction. Our comments are summarized below:
Water Comments:
Need to have sleeves or separation between all existing potable water lines and mains from the sewer mains and lines.
Please note any crossings of other utilities on the plan sheets.
Please note on the plans that there must be 10 feet of horizontal and 1 and ½ feet of vertical clearance between sanitary sewer.
Are there any new fire hydrants required for this new building expansion?
Please include and show on the water plans, all location and callouts for all crosses, tees, bends, connections, adapters, couplers, valves and length and size of pipe.
Is there any new water or irrigation meters for this project? If there are, please include them and locations on the water plans.
Crosses require 3 gate valves and tees require 2 gate valves.
Please include and show on plans thrust blocking where required.
Sewer Comments:
Please take note that some of the sanitary sewer gravity flow lines, appear to be at the minimum allow percentage of slope. There will be no allowance for any less of a slope on the
gravity sewer lines per slope requirements.
Please include on the sewer plans location of all connections, valves and bends.
Please include on the sanitary sewer plans and details, the type (Manufacturer) of sanitary sewer step tank.
Step Tank depth of bury not to exceed 60” from top of upper most riser lid to invert of inlet pipe to tank.
Is this a duplex pump system?
Manholes need to be constructed in such a way as to allow NO infiltration. Prefer to have no man holes or piping through the manholes with clean-outs available within the manholes.
No clean out needed at end of service line.
Hose bib req. within 50’ of tank
Supply calculations supporting this proposed tank size.
Need full set of submittals on this proposed tank.
Grading and Stormwater Comments:
Show finish grades on plan sheets.
Show profile drawing which should include all stationing and number of catch basins and manholes, rim elevations, inverts (In and Out), length and size of pipe.
Street:
Please include a plan view that shows spot elevations on curb returns.
Landscape and Irrigation Comments:
Final landscape plans have not been included in the civil plans. Please request 2 sets of final landscape and irrigation plans.
Final landscape plans were not submitted. The civil plans shall include 2 sets of landscaping plans in accordance with Chapter 17.80 YMC, including provisions for irrigation and for
maintenance of landscaping.
As stated in the approval, a Type II landscape buffer consisting of an 8 foot planter strip is required along the east property line. The existing landscape strip located along the
east property line can be continued south to the point where the soccer field begins. The landscape plans shall also include the location of all refuse containers, including access
approved by the service provider.
Construction Plans:
Please include on plans, a Profile Drawing in which should include: Profile grades, Scale for both Horizontal and Vertical, Stationing, vertical elevation increments and existing utilities.
Miscellaneous Items:
Staff or Hearing Examiner Conditions of Approval must be included on the Cover Sheet.
Title Block must be included on all sheets and should include: Design By, Drawn By, Date and Checked By.
Please include sheet numbers and total sheets on all sheets of plan set.
Please include Revision Block on sheets.
I did not see Survey Monumentation on the plan sets; I could only find survey reference points. Stating to expose connection points and verify fittings.
Field verify note on drawing
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.
