BLAKEBURN LAGOONS PARK | Public Information Session 2 | July 19, 2016

Thank you for coming to the second Blakeburn Lagoons Park Public Information Session!We presented two park plan options at the first Public Information Session held in May 2016 and used your feedback to refine the preferred plan to better represent your ideas.

Please review the display boards and share your comments and ideas. We will use your input to further refine and detail the preferred park plan.

OverviewThe Blakeburn Lagoons site is home to two waste settling ponds that were decommissioned in the 1970s. It has been designated for a public park since the 1990s. Recent federal-provincial-municipal funding has now made this possible.

The project will:

Provide a natural oasis for the neighbourhood and entire community

Improve habitat for wildlife, birds and aquatic species

Improve hydrological (water-flow) issues on and around the site

Questions?

Please speak to staff from the City of Port Coquitlam and ISL Engineering and Land Services (who are developing the park design)

GOALS FOR TODAY:1. Outline design goals for the proposed park2. Outline feedback from the May Public Information

Session 3. Present the preferred and refined park plan4. Describe proposed features in the new park5. Get your feedback

2 - PROJECT VISION AND GOALS

PROJECT GOALS

1. Improve site hydrology2. Enhance site ecology3. Introduce public park amenities

PROJECT VISION

The project vision is to convert the decommissioned Blakeburn Lagoons sanitary detention facility into a community scale, natural public park with improved hydrological and ecological function.

Design Response:

Increased car traffic on Elbow Place with a parking lot off the south end

No new parking lot proposed in refined park plan

Existing vegetation retained where possible. Quick park construction in bird non-nesting period

No shelters in the park; open sightlines to and within the park; Vandal Watch program in the park

Disturbance to wildlife habitat during park construction

Concerns about vagrancy and teen use of park at night

We received feedback from you at the May 2016 Public Information Session. Feedback was received through verbal comments and the questionaire form at the event as well as comments through an on-line survey. A summary of the feedback we received is outlined below.

We presented two different park plans at the May 2016 Information Session. Based on your comments and feedback, Park Option #2 (“Nature’s Renewal”) was determined to be the preferred plan. In response to your comments, we have refined the park plan. This plan is shown here today.

DESCRIPTIONThe park concept plan focuses on the enhancement of wildlife habitat and ecological function of the site. Public park access and amenities are introduced but are not the primary design driver.

Features:• Reshaped and connected lagoons converted into

a constructed wetland

• Neighbourhood stormwater redirected to wetlands to retain water levels

• Wetland islands - most dedicated to wildlife habitat

• Multiple vegetative zones (woodland, grassland, emergent wetland) for diverse wildlife habitats

• Wildlife habitat features - tree snags, sunning rocks, bird houses, bat boxes, ephemeral ponds

• Phytoremediation and biofiltration planting to remove contaminants from site soil and water

• Capping of contaminant soils in areas of public access

• Native planting where feasible

• Looped walking trails throughout the park

• Vegetated buffers between environmentally sensitive areas and publically accessible areas

• Viewing platforms and wildlife hides at key vantage points

DESCRIPTIONThe new Blakeburn Lagoons site will be a “constructed wetland” – an artificial water body that will use the natural functions of vegetation, soil, and organisms to improve water quality. In this case, the constructed wetland will also serve as habitat and provide public open space.

The wetlands will be ecologically and hydrologically enhanced by:

• Directing neighbourhood stormwater to the site to help maintain water levels

• Deepened to introduce areas of cooler water

• Linked to allow water movements between the two water bodies

Constructed wetland: under construction

Constructed wetland: post construction

1. SETTLEMENT POND:Stormwater is directed to the wetland, where pollutants settle to the bottom.

2. BIO-FILTRATION BEDS: Water is filtered by micro-organisms and algae. This removes pollutants as well as nitrogen, which helps reduce algal blooms.

3. OUTFLOW:Cleansed water is released into the municipal storm-sewer system or a local water body.

Wet meadow: Surround wetlands and are occasionally submerged. They stabilize banks, provide food for mammals and birds and allow safe access to and from the water.

Emergent plants: Rooted in shallow waters, providing habitat for fish, mammals and birds and removing pollutants from the water.

Water Quality Enhancements: Plants and microbes remove pollutants, metals, harmful bacteria and pathogens, inorganic and organic matter from the water. Plants limit algal growth and oxygenate the water.

Submerged Aquatic Plants:Rooted in deeper waters, they oxygenate the water, provide surface for beneficial bacteria and lessen the effects of decaying material.

Floating Aquatic Plants: Rooted in the banks or bottom, floating plants shade the water below, reduce algae growth, cleanse the water, and provide wildlife food and shelter.

Upland: Woody vegetation surrounds the wet area, providing wildlife food and shelter as well as nesting and predator habitat.

How Wetlands WorkWetlands are complex ecosystems where a range of plants, animals, bacteria and microbes co-exist.
