As part of the City of Sarnia’s plan to eradicate phragmites in the municipal stormwater management facilities, closures are taking place this week to assist with phragmites spraying.

During the closures, the entire stormwater facilities will be inaccessible to the public. The closures planned, weather permitting, include:

  • The Suncor Nature Way stormwater facility (1500 Modeland Road);
  • the Heritage Park stormwater facility (1633 Heritage Park Drive); and
  • the 402 Business Park stormwater facility (171 Business Park Drive).

These areas have a high concentration of phragmites, which has been causing damage to stormwater management facilities.

Members of the public have been asked to keep out of these areas for their safety. Signage will be posted 24 hours in advance. A spotter will be on sight for protection of pedestrians who inadvertently enter the trail near the work zone.

Eradication involves spraying the affected areas with pesticide. Following eradication of the phragmites, a suitable seed mix will be applied to allow native species to return to the area and limit the opportunity for invasive species to re-invade. City Staff will consult with Lambton Wildlife Committee and the Sarnia Environmental Advisory Committee to select an appropriate seed mix for the area.
