Seek input & comments forconsideration in the selection of thefinal preferred solution
Welcome
Public & Stakeholders should:
Sign the registry
Review the presentation material
Ask questions of the Townshipand/or Consultant
Submit a comment sheet & indicatewhether or not you want to be keptinformed of the process
3Tatham Engineering
The objective of the study is to:
Undertake a review of bridgereplacement alternatives & improvevehicular access to Reinbird Street
The purpose of the study is to:
Develop alternative solutions toimproving vehicular access
Identify the location, extent &sensitivity of affected environments
Assess the alternatives givenpotential environmental impacts
Identify a preferred solution
Establish measures to mitigateadverse impacts
Study Purpose & Study Area Municipal Class EA Process
The study follows the Schedule B Class EA guidelines to include:
Phase 1 Phase 2
Includes opportunity for public input: PIC (today) 30-day review of final report &
findings
Following completion, the Township may proceed to implementation:
Phase 5

Existing conditions:
The existing Reinbird StreetBridge is a 5.5 metre (18’)wide, 15 metre (50’) spanbailey truss bridge installed in1994 and located over theColdwater River. The structurewas repurposed from atemporary structure crossingBayou Canal / WestshoreCrescent
Items identified during the bridge inspection for replacement in 1‐5 years include: Overall structure hand rails,
wingwalls, abutment walls,girder, bracing, coating
Full replacement recommended
Problem Identification
6Tatham Engineering
Existing conditions:
Load limit prohibits:• Fire trucks• Fuel delivery• School buses• Garbage trucks• Construction
equipment• Access for Sewage
Pump Station
Hydraulics assessment: Isolated flooding impacts
at 5 year storm levels.
Low potential for ice ordebris blockage.
Problem Identification Is a 9 tonne load limit appropriate?
In 2018 an Evaluation of theexisting bridge wasundertaken based on 2017bridge inspection and siteinvestigations and measures.A load posting evaluation wascompleted in accordance withthe Canadian Highway BridgeDesign Code (CHBDC). Thetransom (floor beams) are thelimiting factor in load limitsfor the bridge.
Based on the evaluation, the 9tonne load limit is consideredappropriate for single axlevehicles. However, this can beincreased to 17 tonnes for a 2axle vehicle and 24 tonnes fora 3 axle vehicle (recognizingthat the effective load isdistributed over the vehicleaxles).
However, these loads remainrestrictive to heavy vehicles asthey typically exceed thepermitted limits.
Problem statement:
An improved and/oralternative means ofvehicular access isrequired to ReinbirdStreet to ensure safe andefficient access for allresidents, whilstminimizing impacts tothe surroundingenvironments.
BRIDGE LOAD LIMIT
SINGLE AXLE 9tTANDEM AXLE 17tTRI-AXLE 24t
7Tatham Engineering
Key elements of Alternative 1
The load limit remains – onlycars & light trucks can legallycross the bridge.
Safety issues/concerns nototherwise addressed.
Full replacement of thebridge likely needed in 8+/-years
• Bridge abutmentswould be 100 yearsold
• Replace with “fullload” bridge
Do nothing is consideredwhen financial and/orenvironmental costs of otheralternatives outweigh thebenefits.
Alternative 1: Do Nothing
8Tatham Engineering
Key elements of Alternative 2
The existing bridge would berehabilitated to remedy theload limit and support heavyvehicles.
The continued deteriorationof remaining elements maywarrant full replacement in10-30 years
A temporary access road orcrossing would be requiredduring construction.
The character of the bridgeremains unchanged (untilreplacement).
Alternative 2: Rehabilitate Bridge
9Tatham Engineering
Key elements of Alternative 3
Bridge superstructure to bereplaced to support heavyvehicles.
Existing abutments to bemaintained to avoid works inthe Coldwater River.
A temporary access roadwould be required duringconstruction.
Alternative 3: Replace Bridge in Same Location
10Tatham Engineering
Key elements of Alternative 4
Reinbird Road to be extended toconnect to Charles Street.
Some property & natural environmentimpacts will result.
Minor road realignment may be required.
The existing bridge would remain duringconstruction to serve traffic thus noneed for a detour.
New access point benefits residents,service & emergency vehicles.
Minimal work on existing propertiesrequired (driveways, etc.)
Alternative 4: Road Extension Along River
11Tatham Engineering
Key elements of Alternative 5
New access road to be constructed toWest Street to serve all traffic.
New access point benefits residents,service and emergency vehicles.
Some property & natural environmentalimpacts will result.
Minimal work on existing properties –driveway, water and sanitary services;
Alternative 5: Road Extension Between 2 & 4 Reinbird Street
12Tatham Engineering
Key elements of Alternative 6
New access road to beconstructed to West Street.
New access point benefitsresidents, service andemergency vehicles.
Property & naturalenvironment impacts willresult.
Disturbance to existinghomes include:
need new driveways disturb yards
New servicing to allproperties including newSPS connecting to newROW.
Existing SPS to bedecommissioned & replacedalong new road ORplacement of easement.
Alternative 6: New Road Along Rear of Reinbird Street Lots
13Tatham Engineering
Additional Options for Alternatives for 5 & 6:
Extend Reinbird Street northerly to access 4 & 6 River
Street
Extend road & new servicing down Uhthoff Trail,
connecting to Sturgeon Bay Road
The options including construction of a new road down
Uhthoff Trail were not assessed further as their construction
included connecting to West Street which met the needs of
the problem statement
Assessment of Alternatives
14Tatham Engineering
Evaluation of Alternatives
Weighted scoring evaluation has been employed to reflect relative importance of
evaluation criteria & environments.
Evaluation based on impacts to:
• Physical environment
• Natural environment
• Social environment
• Cultural/heritage environment
• Economic environment
• Climate change
• Future community opportunities
• Review Agency
