Moncton

Location: Riverfront Park

Address: Moncton, NB

The LID demonstration site at the Riverfront Park was designed in consultation with CBCL Ltd, in Halifax, as well as the property owners and Atlantic Stormwater Initiative staff. The LIDs were located on a part of the property that has experienced flooding and that is easily accessed by the public.

The site was designed to be able to handle the first 15 mm of a rain event on site. A combination of a vegetated bioswale with several examples of permeable hard-surface options was installed in October 2016.

The bioswale is placed along the riverside edge of the parking lot to best capture the runoff from the surrounding parking lot. The bioswale has a 0.5 m deep bed of aggregate, acting as water storage, and connects to the municipal storm drain system. This is covered by topsoil and compost and has been planted with native species.

The permeable hard surface options were installed on a 1 m-deep bed of aggregate, topped with a 5-15 cm thick layer of pea gravel. The following were then installed in adjacent sections:

Grass grid pavers, supplied by Core Systems

Gravel grid pavers, supplied by Core Systems

Concrete grass pavers, supplied by Shaw Brick

Cement semi-permeable pavers,  supplied by Shaw Brick

A 200 sq. ft permeable asphalt pad was installed by Dexter Construction.

The excavation work was completed by Price Landscaping, and the Petitcodiac Watershed Alliance were invaluable assistance with filling and planting the bioswale.

Aggregate for the site was supplied by Dexter Construction.

Signs will be installed at the site to highlight key features.
