VICTORIA PARK COMPREHENSIVE MASTER PLAN<br />

<strong>Final</strong> <strong>Re</strong><strong>port</strong> • June 2013<br />

Sea Level Rise <strong>Re</strong><strong>port</strong> (2012)<br />

In 2012, faced with the ongoing need to plan for and address the implications <strong>of</strong><br />

climate, a team <strong>of</strong> climate scientists prepared a re<strong>port</strong> on the impacts <strong>of</strong> sea level rise in<br />

<strong>Charlottetown</strong>. The Projecting and Visualizing Future Extreme Levels for Climate Change<br />

Adaptation in <strong>Charlottetown</strong> Harbour, Prince Edward Island, Canada, written by Forbes,<br />

Webster, and MacDonald, summarizes the current understanding <strong>of</strong> sea level rise and<br />

extreme water levels in <strong>Charlottetown</strong> Harbour and presents information on the extent<br />

and depth <strong>of</strong> flooding that may be expected during severe storms over the next 100<br />

years.<br />

The study presents three plausible scenarios for future high water levels in<br />

<strong>Charlottetown</strong> and the surrounding communities. The predictions combine these sealevel<br />

scenarios with statistics for storm effects (combined tide and storm surge water<br />

levels) to project 100-year storm water levels in 2100. The high water levels obtained for<br />

the three scenarios are as follows:<br />

»»<br />

5.00 m Chart Datum, (3.31 m CGVD28)<br />

»»<br />

5.28 m Chart Datum, (3.59 m CGVD28)<br />

»»<br />

5.73 m Chart Datum, (4.04 m CGVD28)<br />

These numbers are respectively 0.77 m, 1.05 m and 1.50 m higher than the historic record<br />

water level.<br />

For planning purposes, the <strong>City</strong> <strong>of</strong> <strong>Charlottetown</strong> currently adopts a flooding prediction<br />

for the harbour derived from a 2002 study (McCulloch et al.). This prediction assumes<br />

a local sea-level rise (including land subsidence) <strong>of</strong> 0.7 m over 100 years and suggests<br />

that a 100-year storm event occurring in 2100 could reach an elevation <strong>of</strong> 4.93 m Chart<br />

Datum, (3.24 m CGVD28).<br />

Forest Management Plan (2006)<br />

The Forest Management Plan for <strong>Victoria</strong> <strong>Park</strong> was written by Gary Schneider <strong>of</strong> the<br />

MacPhail Woods Ecological Forestry Project. The plan looks at the existing woodland<br />

areas <strong>of</strong> <strong>Victoria</strong> <strong>Park</strong> and arrives at several negative conclusions regarding the<br />

forest health. These include the fragmentation <strong>of</strong> the forest, vandalism and litter, an<br />

abundance <strong>of</strong> invasive non-native plant species, and a general lack <strong>of</strong> attention to<br />

forest health.<br />

Many <strong>of</strong> these issued have since been addressed, and to great effect, by the hiring<br />

<strong>of</strong> a <strong>Park</strong>land Conservationist who has instituted many <strong>of</strong> the remediation principles<br />

outlined in the plan. These include the use <strong>of</strong> silviculture techniques, trail renovations,<br />

the removal <strong>of</strong> invasive, and the planting <strong>of</strong> more native plants and trees.<br />

Additional long-term remediation techniques included in the plan were:<br />

»»<br />

Change the way people view <strong>Victoria</strong> <strong>Park</strong><br />

»»<br />

All work should be <strong>of</strong> the highest quality<br />

»»<br />

Plant more native plants and explain why you are doing this work<br />

»»<br />

<strong>Re</strong>novate the existing trail system and make woodland walks more welcoming<br />

»»<br />

Carry out an intensive removal <strong>of</strong> the worst <strong>of</strong> the non-native species<br />

»»<br />

Be friendly to both the forest and its wildlife<br />

»»<br />

Use plants instead <strong>of</strong> fencing wherever possible<br />

Additionally, the most conservative scenario is a minimum <strong>of</strong> 0.70 m higher than the<br />

water level <strong>of</strong> the earlier study. The selection <strong>of</strong> a design-to water level for future<br />

planning purposes is ultimately a municipal planning policy decision. Nonetheless, these<br />

most up-to-date scenarios and their implications require serious consideration, especially<br />

when evaluating shoreline stabilization and open space facility design for <strong>Victoria</strong> <strong>Park</strong>.<br />
