FEMA Storm Drainage Outfalls
Project complete.

Update 8/6/2013:
The Oufall project work is substantially complete!  Thank you to all for your patience and cooperation as the work interrupted the flow of traffic!    The next phase of the stormwater work is installation of the collection system that will convey stormwater to the outfalls and into the Corp ponds.  The collection system work has started and you can follow its progress on the 2009 FEMA Drainage Mitigation, 13th St to 16th St project page.

Update 7/29/2013:
The 1300 block of Main Street will be closed from 7:00 am to 1:00 pm Tuesday, July 30, 2013.  M. L. Albright & Sons will be paving a portion of the 1300 block of Main Street.  Detour routes around the work area will be signed and access preserved for local businesses. Dairy Queen’s drive through will remain open.  This work is final paving of the Outfalls portion of the FEMA funded Stormwater Drainage Mitigation project.
 
Update 7/11/2013:
Final work placing large riprap in the Levee ditch (see picture below) is wrapping up this week as is the backfill and prepping for pavement at the 9th street outfall. Hydro seeding in the Levee park areas disturbed by construction is being coordinated with the Corps of Engineers’ irrigation schedule.  Next time you are in the park area along the bypass, check out the work at the ponds.

Work will be reestablished just west of the Main Street/13th Street intersection beginning Friday, July, 12 to place the last manhole and sections of pipe. Both lanes of Main Street will remain open with lanes shifting to accommodate the work zone. Dairy Queen’s drive thru will remain open throughout!

Update 7/1/2013:
The Levee Bypass will be opened to traffic Tuesday, 7/2/2013 at 5:00 AM.  Thank you for your patience during this closure!

Update 6/27/2013:
Work in the Levee Bypass continued this week.  The recent rains caused sufficient delay that a one day extension of the closure is required.  Paving of the Levee Bypass Road is now scheduled for Monday, July 1.  The road will re-open to traffic on Tuesday, July 2.

The City of Lewiston Public Works Department and the project contractor, M. L. Albright & Sons, will be working thru the weekend to ensure the work is completed as quickly as possible. 

Informational signs with closure dates were installed Thursday, June 13 and detour routes around the work area will be signed. The Corps of Engineer’s walking path along the crest of the levee will remain open to all users throughout the project.

During the coming week (June 3) , Delsol Lane and Main Street will be affected while the final stormwater pipes, catch basins, and manhole are installed with work in 13th Street to follow.  Two lanes of traffic will be maintained at both of these work zones.

The boring equipment was moved to the 13th Street outfall location.  The photo below shows an easy entry past the crane in the Cafe' Sage parking lot.  This is a great up-close location to see construction equipment in action, so grab a coffee and pastry or some lunch and sit outside to watch the action!

The railroad remains open during construction.  The photo below shows the train passing over the 13th Street bore.

All of the boring work is being completed by the bore casing, head, and augur shown in the photo below.  The inside diameter of the casing is either 48" or 54" depending on the location.  If you are no taller than 4.5" feet, you could stand inside the casing!  That is how big it is!
