Rain Garden and Tree Filter Installation
Horne Street Elementary School is located in Dover, New Hampshire and is within the Berry Brook watershed. Horne Street School has been a focal point of the Berry Brook project providing a location to encourage community outreach and exposure to stormwater managment practices. As part of a Watershed Assitanced Grant, a Rain Garden and Tree Filter (completed Raingarden shown on left, Tree Filter under construction shown on right) were completed on the school grounds. These installations took place during the last few days of the school term in 2011 and we thank everyone, including the teachers, staff, and parents, at the Horne Street School for their continued support of this project!
A watershed curriculum was developed and provided to the students of Horne Street School. This curriculum contained learning activities related to the installation of the bio-retention systems and introduced students to the concepts of the water cycle, function of a watershed, infiltration of stormwater, a visit to Berry Brook (the waterbody that receives the stormwater runoff from their school) and an exploration of the life forms that live in Berry Brook.
Residents of the Berry Brook watershed were invited to a community outreach meeting to introduce the Restoration of Berry Brook Project. Invitations written by project team member Lori Chase and reviewed by the project team were mailed by the Dover Department of Public Works. On June 7 from 6:30 to 8:00 p.m., forty residents attended a presentation by the project team followed by questions and discussion. In addition, at the community meeting announcements of the available opportunities to participate in the rain barrel project, to install residential rain gardens, and to have a residential stormwater audit were presented. The rain barrell workshop took place on June 21st from 5:00 to 6:00 p.m. where attendees received their requested rain barrels.

On June 22, 2011 a Strafford County Community Service work crew worked with Prof. David Burdick of the University of New Hampshire to remove invasive species from the wetland restoration site at the waterworks. Targeted species included oriental bittersweet. Additional invasive plant management, particularly of Japanese knotweed will occur during construction activities and a long-term invasive management plan will be developed for the site.
Berry Brook clean-up days were scheduled from June 22 through 25. Streamside residents received a letter from the City informing them that workers would we coming along the stream across their property unless the landowner objected. A crew worked from the Cocheco River confluence upstream to Roosevelt Avenue. At Sixth Street they piled a truckload of trash and debris, including construction materials and tires from the area downstream of Dover Crossing condos. Debris removed is depicted in the photograph to the right. The crews will return in the fall after more intensive preparation with riparian landowners for access to the stream bed.
In addition, prior to restoration activities at the Water Works site, the City removed debris including general refuse, steel, concrete and transit pipe, railroad ties, and other materials which accumulated at the site in it's 100+ year history of municipal use. This debris was segregated and disposed at appropriate recycling or waste disposal facilities.
Monitoring of Aquatic Life
Three different sections of Berry Brook were electrofished on May 26, 2011. An upper site located upstream of Ash St., a middle site located upstream of Hough St. and a lower site located upstream of Sixth St. Various aquatic species were collected during the survey including white sucker, American eel, fallfish, common sunfish and hatchery brook trout.
