Public Meeting - Drains on Monday, May 28, 2018
Disclosure of Pecuniary Interest and the General Nature Thereof - None disclosed.
Prior Municipal Drain - Branch "C"
The purpose of the meeting was to review the process to date, discuss the technical
aspects of the engineers report only. At the last meeting on March 26, 2018 it was
determined that there were property line adjustments due to a severance that needed
to be considered. Changes to the report have been made.
Henry Huotari from Parsons Inc. was in attendance to discuss details of the Prior
Drain that runs along Fruit Ridge Line in the Municipality of Central Elgin. The
Municipality installed some catch basins and pipe systems some time ago on Fruit
Ridge Line and outlet them on private property into a ravine, which led South to
the Prior Drain. Unfortunately these systems were installed without legal status
under the Drainage Act which has led to erosion issues on private property that
was brought to our attention by landowners. We are here to remediate those issues
and provide legal status for the Drain.
The proposed design to alleviate erosion issues on the McQuiggan property will involve
the reconstruction of the tile outlets through a gabion basket headwall. Sub-drain
will be used behind the headwall to capture any excess surface water that percolates
through the granular backfill behind the headwall. The clay tile will be connected
to a new corrugated plastic pipe and this will outlet through the headwall. Any
overland flow will spill over the headwall into the stream channel. The channel
immediately downstream of the headwall will be reconstructed and an erosion control
blanket will be placed to a distance of approximately 20 meters downstream of the headwall.
The natural channel and tile drain will be incorporated into Prior Drain Branch
Geotextile and rip rap shall be placed at the second catch basin outlet to mitigate
the erosion that is occurring. The catch basin outlet will continue to as overland
flow until it connects with the natural channel.
The proposed ditch along the property line of Lots 17 and 18 will be cleaned out,
widened and the side slopes will be reconstructed and berms installed to facilitate
better drainage and minimize future erosion. The ditch will be extended to connect
with Prior Drain Branch ‘B’ via overland flow paths through the treed swamp at the
south end of the ditch. This ditch/open drain was designed to convey, at a minimum,
the 2 year storm flow of 178 l/s. This ditch shall provide sufficient outlet for
the road authority drainage and all lands connected to this drain. This proposed
ditch shall form the part of Prior Drain Branch 'C'.
There were no questions from any affected landowners or Council members, the meeting
was adjourned, and a provisional By-law concerning Prior Drain Branch 'C' will be
placed on a future agenda for Council's consideration.
The total cost for this project is $76,047.58 which includes all administration, construction,
and engineering costs.
