Fourth Review of Civil Construction Documents
Mr. McInnis:
The City of Yelm has completed the third review of the proposed Planned Residential Development. Your application included:
Transmittal
Comments regarding Third Review letter from City of Yelm
Full Size Plans
Drainage and Erosion Control 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. The bold information following the comment is how we would like to address this issues.
Sewer Review:
The plans do not show or called out the fittings or types of connections, valves, bends or couplers used on the reclaim water line relocation. These should be shown on the plans. Please
provide a revised sewer sheet with these call outs.
Pump Control Panels are not allowed on living spaces. It is unclear if the locations are living spaces or not. Please provide documentation showing this is not a living space. You
can provide this by fax or email.
All utility crossing need to have 18” of separation or sleeving will be required. The sewer and reuse water lines will need to be sleaved when conflicts with domestic water. Concrete
encasement is not allowed. This does not need to be addressed on the plans however we will require at preconstruction meeting.
The step system is utilizing OSI 20 GPM pumps. It is recommended that 2” service lines be installed between the tanks and sewer mains. This does not need to be addressed on the plans
however we will discuss at the preconstruction meeting.
Sta. 3+00 has 2-11.25 degree bends called out. I do not see a reason for these to be installed. Please remove these callouts at the time of sewer sheet resubmittal.
Looking at the process for relocation of the water sewer and reuse mains it appears that couplings would be more benificiatial to use instead of tapping. These does not need to be addressed
on the plans however will be discussed at the preconstruction meeting.
Water Review:
The Master Meter and Reduced Pressure Backflow Assembly can not be installed direct.
Please show and call out on the plans, the 10x10x3 Tee or the hot tap for the connection of the domestic water supply from the 10” main to the 3” water meter for the buildings. This
does not need to be addressed on the plans however will be discussed at the preconstruction meeting.
Please show and call out on the water plans, the Hot Tap or Tee for the irrigation connection. This does not need to be addressed on the plans however will be discussed at the preconstruction
meeting.
Please show and call out the Hot Tap or Tee for the fire system on the water plans.
This does not need to be addressed on the plans however will be discussed at the preconstruction meeting.
Fire sprinkler meter, potable irrigation meter and irrigation water meter will need to have reduced pressure backflow assembly installed behind meters. This needs to be addressed on
the water plan and resubmitted for approval.
Planning Review:
Landscape Plans were not included. Please provide a final set of landscape plans. This comment as been shown on all review letters. Please submit the landscape and irrigation plans
for review and approval.
Please review and revise the water and sewer plans as requested. You may email the 3 sheets to me for review and approval. If you have any additional questions or comments please do
not hesitate to call or contact me at jimg@ci.yelm.wa.us.
