MEMORANDUM
DATE: May 12, 1989
TO: Sherry Albertson -Clark, Senior City Planner
FROM: Bob Smith, Stormwater Utility Manager 6,V
RE: Newnote Annexation Comments
Following are my comments on the Newnote Annexation.
- 1st and 2nd sheets from Fox Meadows Master Plan -- Master plan identifies
40' open channel through the site (see attached)
- Floodplain map, 3rd sheet shows floodplain limits and flood elevation for
the site at these locations. (see attached)
- To meet current floodplain regulations structures need to be flood
proofed to an elevation of 18" above water surface elevation.
Floodproofing equals elevating the structure, floodproofing of doors,
entrances, etc.
- Site drainage could go into lakes (existing) if adequate storage is
available (outlet from H.P. also maybe included in this.)
- Drainage crossing of Harmony unknown at this time. Preliminary design
flows 4500 cfs.
- Issue that needs to be addressed is definition of floodway, by 6" or 1'
rise criteria. City = 6" Federal = 1'
