Re: Fox Hollow P.U.D
Final Plan Review
BRA File No. 55 -04 -000
Dear Eric:
We have reviewed the updated final plans for the proposed Fox Hollow development as
submitted by Stevens Engineering and have the following comments and/or recommendations
for your consideration:
Site Layout and Utility Plan Sheet 2 of 7
1. Specify on the detail the type of cover to be placed on the curb boxes located in the
pavement. If the type of cover is called out in the specifications please provide a
copy of the section.
2. For the south building the gate valve symbol for both the 6" and 4" valve are not
shown on the drawings. In addition, the 4" gate valve is not called out.
Grading, Drainage and Erosion Control- Sheet 3 of 7
1. Detailed design drawings and calculations for the retaining walls shall be submitted to
the City for review and approval prior to construction.
2. Details should be submitted for the location where the storm sewer is flush with the
retaining wall. To prevent erosion at this location, it is recommended that rip rap be
placed below this pond inlet.
3. The drawings show the Emergency Overflow for the pond over the east retaining
wall. Provide detail of this EOF.

Details- Sheet 6 of 7
1. The cross section view of the Outlet Structure Detail does not match the 3D view. In
the 3D view the two 15" diameter orifices should be raised to match the elevation of
the outlet pipe.
Developer's Agreement
1. Attached is the revised cost estimate for the Plan A improvements.
2. Items such as retaining walls, parking lots and trees are located within the drainage
and utility easements. A paragraph should be included in the Developer's Agreement
stating that the Developer will be responsible for all costs necessary to repair or
replacement private improvements, should the City ever need to repair, replace and
maintain the pond and public utilities located within the easements.
Easements
1. The utilities and ponding area are located within the drainage and utility easements.
General Comments
1. Prior to issuing the grading permit the developer should provide the City with a
signed copy of the easement from Xcel energy.
2. The fire chief should approve the plans prior to the City issuing the grading permit.
