HUMAN INTERVENTION CAUSES BEACH EROSION ON PUBLIC COASTLINE

Oceanside prides itself on the fact that it is located along some of the finest beaches in British Columbia. People from around the world come here to enjoy the coastline and many of them retire here after multiple vacations. As a result the population is growing rapidly and demands on the shoreline have increased.

Parksville Beach has changed a great deal since I graduated from high school. Over time pavement, fences, grass fields, and blasted rock have taken over from the natural aquatic grass and sand. A hovercraft, operating from the coast guard station at the end of the point, regularly drove out over a flat beach at low tide and launched itself into the water. Today a massive gravel bar has emerged just off shore from this same point.

According to some experts the erosion of the Parkville’s shoreline may be the result of tidal and storm pressures being deflected into the bay by this large gravel bar. As a result the city has installed sections of blasted rock to prevent the paved road from being washed away. The City of Parksville is considering more changes to the shoreline in an attempt to stop this type of erosion.

The main change to that section of coastline is the massive blasted rock causeway built by Surfside RV Resort, dividing the Englishman River Estuary Floodplains from the Strait of Georgia. Man made changes to the natural coastline effect the flow of water by redirecting tidal and storm surges. All along the coast private land owners have installed dikes, concrete walls, and other barricades in order to alter the natural erosion of the shoreline.

An area known as the ‘Queen’s Land’ along all waterways was once protected from development but today it is very easy to obtain a license which allows property owners to alter the coast. Governments at all levels have abandoned the protection of the shoreline in exchange for increased tax revenue from expensive waterfront properties. However, there remains a legal right of way along all waterways which is accessible to the general public which can not legally be blockaded by private property owners because the ‘Queen’s land’ belongs to all citizens of Canada.

In September the Stewardship Centre for British Columbia announced that it had been awarded a grant of $100,000 by the Real Estate Foundation of British Columbia for the Green Shores sustainability project. With a focus on social and economic development, the Green Shores Project aims to promote healthy coast and marine ecosystems by planning a design while working to benefit the environmental. It provides positive examples for property owners, developers and design professionals to address environmental and sustainability issues associated with increased waterfront development. Unfortunately, as a non-profit society it cannot enforce it’s recommendations but does provide information and tools to assess shoreline property and habitat protection.

“The need for sustainable approaches to waterfront development in the Georgia Basin and Strait of Georgia is accentuated by unprecedented residential and commercial growth,” said Project Coordinator Patrick Walshe. “Frequently we try to immobilize shorelines with cookie cutter solutions, yet too often this destabilizes the shore and its ecosystems, jeopardizing our coastal resources as well as the beauty and character of our coastal communities. There are many green alternatives in our tool kit, which can be catered to solve site specific issues more effectively.”

The project team will help to educate land managers, designers, planners, developers and builders working on ocean front development on Vancouver Island and the Georgia Basin, in an effort to develop alternative design concepts.
