Re: Old Town North Fourth Filing; Fort Collin, Colorado
Dear Stormwater Utility,
Old Town North Fourth Filing consists of primarily of the replat of Tract HHH to create an
additional lot on Block 9 that was considered with the original Old Town North design. Old Town
North Fourth Filing will also consist of completing the lots adjacent to Osiander Street that were not
completed with the original Old Town North development due to the Dry Creek floodplain defined at
the time of development of Old Town North. The Dry Creek floodway has since been redefined by
the Flood Insurance Rate Map (FIRM) Map Number 08069C0977G; Panel 977 of 1420; map dated
June 17, 2008.
The drainage basin for the affected area of block 9, Old Town North included with this project was
included in the Drainage, Sediment/Erosion Control and Stormwater Quality Report for Old Town
North Third Filing as approved by the City of Fort Collins Stormwater Utility. Drainage,
Sediment/Erosion Control and Stormwater Quality the affected area of block 9, Old Town North
included with this project have been accommodated with the Old Town North Third Filing
development.
All runoff from the affected area of block 9, Old Town North included with this project, is conveyed
to four (4) curb inlets on the south side of Osiander Street near the southwest corner of the
intersection of Osiander Street and Redwood Street. Runoff is then conveyed northerly across
Osiander Street and ultimately to the Old Town North Third Filing rain garden located at the east end
of Old Town North Third Filing. Refer to Basins 3 and 3A on Sheet 19 of 27, Master Drainage Plan
included with the Old Town North Third Filing utility plans and Drainage, Sediment/Erosion Control
and Stormwater Quality Report attached with this addendum for immediate reference.
