The Walley Creek Streamkeepers were understandably worried in August 2021 when we heard that the property beside Pipers Pub (4670 Hammond Bay Rd.) was was for sale. Our group formed when a similar high density subdivision on Hammond Bay Road was granted a development permit within the watercourse protection area.  We've since heard that those homes have problems with flooded basements during rain storms, despite sump pumps moving water out.

The property beside Piper's Pub contains two important wetlands associated with Walley Creek, which manage flow and filter the water as it flows downstream.  For development near wetlands a 15m setback is the default, and the Development Permit Area guidelines outline more details on what is required on specific sites.  You can read the City of Nanaimo's description of their watercourse protection here.  

In February 2023, when the property sold, we streamkeepers wrote a letter to Mayor and Council on behalf of our group, and encouraged concerned neighbors who contacted us to do the same. 

A development permit for 4670 Hammond Bay Rd. was approved by City Council on July 8, 2024.  To see it, go to What's Building in My Neighborhood, and type 4670 as the address and Hammond Bay into the next drop-down box.  Make sure the "show inactive" box is ticked above, then click on the S that comes up on the map..   Two pages of the permit are included below for reference.  To our great relief, the developer is not planning to create any road access to Hammond Bay through the wetland or across the creek. Also, the wetland areas have been protected as parks, and the riparian area boundary is being respected.   What a difference from the last development in our watershed, and an important step to protecting all the plants and animals that thrive in this healthy ecosystem!

In 2017 we picked up the USHP survey where we'd left off at McGuffie Road.  Reach 4 flows through a strata development where people have literally built right on top of the creek.  There are bridges, hardscaping, and no regard for a riparian buffer.  

North of Vista View Cresent are two large wetlands: one is natural, the other is a man-made stormwater detention pond behind a chainlink fence.

At Vista View the City path starts again, and Walley Creek flows parallel to this paved path that gets lots of foot and bike traffic from local residents.  The path continues east and ends near the source of Walley Creek, at Frank J. Ney Elementary school.  We came across a couple of storm drains that empty into the creek behind a townhouse complex south of the Hungarian Cultural Centre.  The City of Nanaimo interactive web map shows that these pipes are conveying rain water into the creek from developed areas between the Linley Valley and Rocky Point.  (To see storm drains: open the interactive web map, then click on themes > utilities, then on the left side click the box that says "storm".  You have to be zoomed in really close for the utilities to show up.)

As we walked upstream the creek switches from one side of the paved path to the other. When we crossed over the paved path to continue measuring, we were awed to see a bat fly back and forth across the stream, dipping into the surface of the water several times before disappearing into a cavity in a nearby tree.  When we reported this to a bat biologist she said it's very unusual to see a bat during the day and we may nave seen a thirsty nursing mother!  The "bat tree" below is obviously also a snack bar for woodpeckers, nestled in a grove of Fir and Spruce trees.

The creek and riparian area along this path are so beautiful.  There is old evidence of logging, but the alders and Cedar have grown up and there is a rich diversity of native species including Oregon grape, trailing blackberry, salal, salmonberry, ferns, vanilla leaf, and skunk cabbage.  The creek flows over silty bottom, with an occasional boulder, but there is relatively little cobble or gravel in the stream bottom upstream of McGuffie Road.  This means the habitat isn't ideal for fish spawning, or the invertebrates fish love to eat.

As we noticed often during our survey, however, the creek supports a wide variety of life besides fish.  After crossing Williamson Road we spotted this little frog cooling off in the water.  Herpetologist Elke Wind advised us that Walley Creek and its wetlands are important breeding habitat for frogs and salamanders that spend the rest of their time in forested areas like the Linley Valley.  Protecting migratory corridors between these two areas (forest and stream) will be crucial for the survival of these fragile species.

Upstream from Williamson Road Walley Creek flows between Harry Wipper Park and the outdoor classroom used by students at Frank J Ney Elementary school.  Here the dominant species is alder, with a few sword ferns.  The skunk cabbage and salmon berry tend to get trampled by children exploring and learning outdoors, and the stream is choked with small woody debris.  With enough flow and slope, small woody debris can have a healthy scouring effect, but if it plugs up the flow it can create erosion on the banks.  This is not a big problem at the headwaters of the creek since the flows are small, even in the winter.  
The question of how to improve biodiversity and stream health at this site is not an easy one to answer.  When the school was built it's likely an excavator dug a channel to encourage the stream to flow in its present path, and to drain water away from the construction site.  Since the original sponge-like infiltration area has been drastically reduced by development in this area we must now look for ways to prevent any further loss of wetland area here at the headwaters, and throughout the watershed.

The beginning of the end.  Just before we reached Entwhistle Drive, the water disappeared.  In the winter there is surface water on either side of Entwhistle Drive as far east as Springfield Place.  Our August Stream survey, however, ended here. 

As Nanaimo continues to grow, there is pressure to increase density on the suburbs.  While this is a smart strategy to combat urban sprawl, it should not be at the expense of life-sustaining wetlands and streams like Walley Creek.  This photo was taken in 2016 before a townhouse complex was built between Fillinger Crescent and Entwhistle Drive.
