You can enjoy time with your 4-legged friend in the dog park, practice riding at one of our three skate parks, take up disc golf, or watch your child's face light up as they explore the many playgrounds found around the city.
The Parks Division is responsible for the general maintenance of all public parks and sports field facilities, managing the city's forestry program, mowing, shrub/flower bed management, playground maintenance, open space and trail maintenance. The Parks Division also provides landscape maintenance for designated medians, streetscapes and rights-of-way.
In partnership, the Parks and Recreation Divisions offer residents and their guests multiple city festivals and celebrations throughout the year. Parks Division takes pride in making our city a place where memories can be made by all!
