Vancouver B.C/Southwest Canada

Vancouver, British Columbia

  • Introduction

    There is ongoing demand for examples of Green Shore approaches for a range of shore types and physical settings, including conservation and restoration of habitat, as well as alternatives to hardened methods of shore protection. This project example gallery is intended to address a range of coastal development issues including brown field re-development and residential waterfront development as well as public space, walkways and park areas.

    Project Submissions

    To build the gallery, Green Shores is providing an opportunity for design professionals to showcase shoreline projects that incorporate some or all Green Shores principles. Projects need not be eligible for Green Shores certification, but do need to demonstrate environmentally-sensitive design options. All submissions are subject to review and approval by the Green Shores Technical Working Group prior to posting on the Green Shores website. Submitted projects may be used at upcoming practitioner workshops.

    To submit a proposed project, download the submission form here. Instructions for completing the template are included in the body of the document. E-mail the completed form to info@greenshores.ca.

    Project Examples

    Projects are organized according to shore type:

    • Sand and Gravel Beaches
    • Low Banks
    • Coastal Bluffs
    • Rocky Shores
    • Estuaries and Lagoons
    • Altered Shorelines

    For more details on shore types, please refer to Part 1 of the Coastal Stewardship Guidepages 22-32.

     

    Sand and gravel beaches  Sand and Gravel Beaches

    Sand and gravel beaches are found where there’s a significant supply of loose sand, gravel or small cobbles. These materials erode easily and are readily transported by wave and current action.  Features such as spits and coastal lagoons can be created when the sediment associated with longshore drift accumulates. Finer sediments, including gravel and sand, are often moved down the coast by wave action and accumulate as pocket beaches in sheltered bays between headlands, or as gravel beaches near high water in small indentations along the coast. Sand and gravel shores are highly sensitive to human interference and interruption of longshore transport processes. Breakwaters, groynes and modifications to the onshore/offshore movement of sediment transport can have serious effects. Coastal plain shores are also susceptible to flooding during high tides, surges and storm waves.

    Southview Beach, Powell River, BC

     

    Low Banks

    Low banks are formed of sediment less than 5 meters in height. They can be considered small coastal bluffs, as many of the physical processes (wave erosion, sediment transport) are similar, with the exception that upland slope processes (surface and groundwater runoff) affect higher coastal bluffs more than low bank areas.

    Coastal Bluffs

    Coastal bluffs are steep slopes where soil and vegetation cover the underlying rock formations. Many of today’s coastal bluffs were formed at the end of the last ice age. Coastal bluffs are an important source of sediment to beaches and coastal spits. Arresting erosion by hardening the toe of bluffs can lead to starving downstream beaches of these sediments.

    Examples:

    Milner Gardens, Qualicum Beach, BC

     

    Rocky shores  Rocky Shores

    A rocky shore typically consists of a solid rock bench across the intertidal zone, that may or may not extend up to the high tide line.  Thin gravel and boulder veneer deposits are often found on these benches, but usually cover less than 10 percent of the intertidal area. This type of shore can also be a near vertical rock cliff that may extend above and below the intertidal zone. Sand, gravel and cobble sediment deposits often form small beaches near the high tide line.

    Estuaries and lagoons  Estuaries and Lagoons

    Estuaries are formed where a river enters the ocean. Rich nutrients and fine sediments carried by the rivers, the variety of habitat created by the formation of deltas, and the mixing of fresh and salt water make estuaries highly productive. They are important nursery habitats for many kinds of fish and invertebrates. As estuaries are generally protected from large wave exposure, the focus of these examples is on sensitive ecological features, including marine riparian vegetation.

    Examples:

    Dick Murphy Park on Tyee Spit, Campbell River, BC

    Richmond South Dike, Richmond, BC

     

    Altered shorelines  Altered Shorelines

    These are shores that have been modified by human activity. Only a small percentage of British Columbia’s shores have been modified, but that percentage tends to be in some of the most productive coastal habitats because people settle in the same areas that are most favourable to marine life – sheltered bays, estuaries and gently sloping shorelines. For this reason, the impact of human activity is significantly greater in some B.C. coastal ecosystems, such as the Georgia Basin, than simple percentages would indicate.
