Presentation Abstract
Coastal processes function on a larger scale than most individual properties can appropriately accommodate. Property frontages typically range on the order of 10s of meters, whereas coastal processes (such as sediment transport) often span 100s of meters or more. These scales pose a challenge for implementing natural and nature-based approaches on many individual properties. Neighbourhood-scale designs have the potential to avoid the site limitations posed by individual properties as well as distribute costs and benefits across a broader community. However, there are few examples of neighbourhood-scale projects being implemented within the Salish Sea to date. Northwest Hydraulic Consultants (NHC) – on behalf of the Stewardship Centre for British Columbia (SCBC) and in collaboration with the Town of Qualicum Beach and the Comox Valley Regional District – developed three neighbourhood-scale coastal adaptation concepts that incorporate Green Shores® for Homes principles and guidance. As part of the project, three conceptual designs were developed for two sites on the east coast of Vancouver Island. A marsh terrace concept was developed to replace an existing hard revetment, and a vegetated backshore nourishment was designed to adapt to sea level rise for two sections of shoreline at a site in Royston, BC. A gravel beach and headland concept was also developed to re-naturalize a long section of existing hardened shoreline in Qualicum Beach, BC. This presentation will introduce the project goals, the project sites, design concepts and anticipated costs, compliance with Green Shores® for Homes guidance, as well as relevant local, provincial, and federal regulatory agency requirements. Challenges and opportunities for future implementation (such as permitting requirements and cost-sharing) will be highlighted.

Neighbourhood-Scale Coastal Adaptation with Green Shores: Challenges and Opportunities
Coastal processes function on a larger scale than most individual properties can appropriately accommodate. Property frontages typically range on the order of 10s of meters, whereas coastal processes (such as sediment transport) often span 100s of meters or more. These scales pose a challenge for implementing natural and nature-based approaches on many individual properties.
