Dear Mayor & Council:
Re: Cherry Lane Golf Course
Irrigation Water Storage
At your request I have reviewed the submittal made by the Engineers for
Leavitt-NuPacific outlining details for the .construction of a debris screening
structure near the irrigation pump station and for the construction of an off-
season irrigation water storage lagoon located in the southeast corner of the
existing golf course lake.
My comments concerning this submittal are as follows:
Debris Screenin Structure.
1. Locate the structure partially into the east bank of the lake or
construct a compacted earth fill out to and partially along its
north and south side to facilitate access for maintenance and for
removal of the screens for cleaning.
2. Revise the detail sketch to show Screen "A" having a 3/8 inch mesh,
Screen "B" having No. 4 mesh and Screen "C" having No. 16 mesh.
3. Verify that the weight of each screen will not be detrimental to its
removal for cleaning purposes.
In my opinion the intent of the screen structure is .satisfied by the
details shown on the submitted sketches.
