NOTES:
• All agreed again that the main contributor to the Thorpe road flooding appears to be: 1)
overtopping and failing berms along Chester Ck, south of the City limits. These berms are
located on private property in unincorporated Spokane County. 2) Chester Ck channel south of
the City limits and the Drainage Easement on Harold Orr's property appear to be filling in with
sediment, debris, and trees that are displacing water from the channel.
• City is writing a letter to County re: the Chester Ck channel and berms south of Thorpe Rd and
how the channel needs cleaned and berms need re -built
• All agreed that channel dredging and berm improvement south of Thorpe Rd is VERY
IMPORTANT to the low -flow flooding solution
• The Golf Course staff would like to keep all low flows off the course
• City needs to look into FEMA floodplain regulations for development near or in a "floodway."
• City is looking into dredging the creek channel north of Thorpe Rd. County completed this back
in 1997.
• More survey work along Thorpe Road has been completed by the City. A third 15" culvert was
found near the existing two 15" culverts. All three culverts are blocked/plugged.
• Golf Maintenance staff believes that the below the fine, silty -loam poor draining soils are good,
well draining gravels and sand. Green #5 in the nw corner of Thorpe and Madison is hard to
keep watered. Lots of dry spots.
IDEAS PRESENTED:
NEW:
• Re-establish a ditch along the south side of Thorpe Rd and either:
• 1) Build a new culvert on east end of Thorpe Rd near the roadway low point. Provide new
gallery of deep drywells near the northwest corner of Madison and Thorpe roads. Connect
new drywells to the existing drywell in the east swale.
• 2) Build a new culvert on east end of Thorpe Rd near the roadway low point. Culvert would
flow into a piped system with two new manholes on the north side of Thorpe road. Pipes
would outfall onto golf course near the northwest corner of Madison and Thorpe roads.
• 3) Build a new culvert on east end of Thorpe Rd near the roadway low point. Culvert would
flow into the existing west swale (the swale with no drywell). Provide a pipe in the swale
draining west into Chester Ck downstream of the bridge.

• 4) Build a new culvert on east end of Thorpe Rd near the roadway low point. Culvert would
flow into the existing swales. Re -grade swales to overflow into or around the course and
discharge near the northwest corner of Madison and Thorpe roads.
OLD (from last meeting on 5/18/2011):
• Re-establish a ditch along the south side of Thorpe Rd and either:
• 5) Connect the two existing 15" culverts with 2 manholes, piping the water back into the
creek below the Thorpe Rd bridge over Chester Creek, install a check valve so water from
the creek would not be able to flow back up the pipe.
• 6) Extend and re -open the two existing 15" culverts under Thorpe Road and daylight into the
Par 3 golf course to the north.
• 7) Build a new culvert on east end of Thorpe Rd near the roadway low point and re -grade
the existing swales to overflow into or around the course. Discharge water by providing
conveyance along the west side of Madison Rd and dispose of the water into a deep bio -
infiltration swale on golf course property and within existing "out of play" area(s).
