Construction Review
RE: Redline Plans dated April22,2009
Dear Mr. Hanington:
We have received comments from the City of Yelm and or¡r response is as follows:
Sewer Comments:
1.As previously discussed with City of Yelm personnel in January regarding
the STEP sewer alignment, it was established that this property lies at the
edge of its sewer basin. Properties to the south lie in a separate basin and
we were informed by city personnel that it was not necessary to continue
the STEP main all across the property frontage.
A sewer cleanout and subject detail has been added to the plans
The proposed connection to the existing sewer main has been detailed on
the plans.
The service connection to the property has been revised to eliminate the
45-degree bends.
The STEP pipeline callouts have been amended to include fabrication
specifications.
This specification has been added to the plans.
The proposed service connection to the STEP main has been detailed on
the plans.
The STEP Ta¡k Sizing Calculations are included with this letter.
