channel and preservation of the existing channel.3. Primary play area near Cordera Crest Avenue. Nature play is integrated into the

riparian area next to the stock pond.4. One primary concrete trail and two secondary trails connecting to the adjacent

communities. Several additional secondary crusher fines and single track trails throughout the park.
