We have reviewed the Construction Plans for Goodwill as submitted by Folz, Freeman, Erickson, Inc. on

Chnn+ r 1 1
1. At the driveway entrance the removal note for the sidewalk should be changed to bituminous
pathway.
2. An existing hydrant is located on the south side of the driveway entrance. Make a note to protect
existing hydrant.

1. Concrete pedestrian ramps with truncated domes shall be constructed on each side of the
driveway entrance,
2. A commercial concrete driveway apron is required at the entrance. As discussed with the owner a

1 All 12" and 1 5" RCP shall be class 5.
2. The 4" FVC pipe in the in i filtration basins should be tailed out as perforated pipe.
3. CBMH 4 is called out as a 48" diameter structure. The top of the 24" pipe to the south and the
bottom of the 15" pipe to the east will be in conflict with a 48" diameter structure. It appears this
structure needs to be increased to a 6'0 diameter.
4. CBMH 9 in the northwest corner has a future storm sewer extened to the northwest. will CBMH 9
have a hole bulkheaded for this future pipe? Or will a new hole be made with the future
connection?
5. Provide rational sheet calculations for the design of the storm sewer.
6. Insulate all storm sewer /water main crossings.
7. The connection to the existing sanitary manhole shall be core drilled. The pavement section for the
patching is called out as C7.1. (In this set of plans there are duplicate detail sheets, C5.1- C5,3
and C7.1 — C7.3)
8. Verify that the hydrant detail/ specs call out the following information.
Fire hyrlrantc shall inr r an AF( - �,I aterous storz N0771e • The hydra nj i 11,n ❑
