GEORGINA ISLAND

Roads Upgrade and Drainage ProjectPresentation to The Community

March 4, 2014

2 Introduction

C.C. Tatham & Associates Ltd. (CCTA) retained by Georgina Island FirstNation (GIFN) to provide professional engineering services for upgrading ofapproximately 10 km of roads;

Introduction

Project includes: Assessment of existing roadway conditions;

Chief Joseph Snake Road, Loon Road, Bear Road and Root Road;

LVM Inc. providing geotechnical advice.

Sidewalk recommendations;

Cost estimates; Drainage improvements;

Life cycle analysis; Recommendations for cost effective reconstruction options;

3 Drainage Overview

Regrading and culvert replacement to provide uniform unobstructed ditches will improve surface drainage;

Chief Joseph Snake Road, Bear Road and Root Road

Drainage Review

Drainage outlets are blocked or missing, restricting flow; Existing ditching is poorly defined, shallow and overgrown;

Drainage concerns between Chief Joseph Snake Road, Turtle Road and the lake related to low topography and maintenance needs;

Outlet improvement at campground on Bear Road.

4 Road Overview

5 Road Overview

Ditching exists only on southwest side, poorly defined and overgrown;Loon Road

Install a French drain on northeast side to collect road surface runoff, discharging to southwest ditch;

Regrade southwest ditch to a uniform positive grade.

6 Geotechnical Evaluation

Thorough evaluation of current roadway conditions:

LVM Investigation

Roadway distresses; Granular base/subbase/surface treatment depths; Road structure materials.

Distresses related to: Relatively flat road profiles; Proximity to wetlands; Undefined outlets and high lake levels relative to road ditches

and road bases; Existing road structure is shallow, substandard granular material; Concluded existing pavements are well beyond their functional service

lives and major rehabilitation is required.

7 Rehabilitation Options

Place 100 mm granular material over existing pavement (utilizing materialquarried on site if available);

Rehabilitation Method - Foamed Asphalt Stabilization

Pulverize granular material and existing road structure to depth of 225mm;

Stabilize pavement surface with expanded (foamed) asphalt to depth of150 mm;

Double layer surface treatment; Regrade all ditches and replace driveway

and road cross culverts.

8 Rehabilitation Options

Full depth excavation;

Other Rehabilitation Options and Lifecycle Analysis

Pulverize asphalt; Mechanical reinforcement. Considers initial capital cost plus 20 years of maintenance; Full depth reconstruction has highest capital cost and 2nd highest

maintenance cost with crack sealing and repaving in year 15; Pulverizing has lowest capital cost and highest maintenance cost with

annual spray patching and surface treatment in years 8 and 16; Foamed asphalt stabilization has 2nd lowest capital cost and lowest

maintenance cost with surface treatment in years 10 and 20; Foamed asphalt stabilization is the most cost effective.

9 Cost Estimates

Foamed Asphalt Stabilization $ 5,560,000;

Construction Cost Estimates

Includes 10% contingency; Includes all drainage improvements within roadway; Assumes imported granular material, may be reduced by use of on-site

quarries; Does not include sidewalk costs; Does not include outlet cleaning/improvements.

10 Sidewalk

Sidewalk 1.5 m widening of south bound lane of road; Low traffic volumes and speeds minimize safety concerns; Delineation of the walkway by line painting; Winter maintenance completed by existing snow removal equipment; Does not alter the established drainage patterns; Does not require work beyond the right-of-way; Estimated construction cost approximately $392,000.

11 Sidewalk

12 Summary

Foamed asphalt stabilization with double surface treatment;

Summary

Most cost effective rehabilitative method to provide adequate structuralcapacity and meet functional service life expectations;

Rehabilitates existing road structure and minimizes placement of newgranulars, thereby reducing costs;

Double surface treatment for hard surfacing is a cost effective alternativeto hot mix asphalt and provides more flexibility during movement of thesubgrade due to frost actions and spring thaw;

Existing granular quarry material may be suitable for this rehabilitationmethod and result in further cost savings.

13 Next Steps

GIFN confirm preferred solution and construction schedule (2014/2015);

Next Steps

Liaison with agencies (MNR, DFO, LSRCA);

Survey drainage outlets;

Assess quality and quantity of island quarry material;

Prepare final design and tender documents;

Circulate to invited contractors for tendering;

Contract award and construction.
