CREEKWAY PARK The Big Picture 10 The larger watershed - where is the water coming from? Creekway Park is an opportunity to construct the first portion of the daylighted stream in Hastings Park. The remainder of the stream will be constructed as the redevelopment of Hastings Park frees up space required for the daylighted stream corridor. Historical Streams - Where did they go? Historically, two streams ran through Hastings Park. In predevelopment times, the streams were fed by the upland watershed. Over the years, as the city evolved, this natural source of water has been intercepted by roads, roofs, and pavement and directed into pipes. The streams were completely erased as their ravines were filled in to provide additional land for development. Reviving a lost stream? The construction of the Sanctuary in 2000 was the first step in re-establishing a stream in Hastings Park. The 2010 Master Plan proposes to connect the Sanctuary to the Burrard Inlet with the construction of a daylighted stream within a wide habitat corridor.

When the combined systems are separated, stormwater from neighbourhoods within the watershed will provide water to the Sanctuary and the daylighted stream.

Captured stormwater will be used to feed the daylighted stream. HB Lanarc-Golder Raincoast Applied Ecology Golder Associates Kerr Wood Leidal Drdul Community Transportation Planning
