:371 Recommended 2009 action: 372 We have scheduled. another workshop for April 29, 2009. 373 B. Sennett Lake Shoreline Improvement Project 374 In 2008, the City of Roseville completed an exciting partnership project with Prince of 375 Peace Lutheran Church and the Ramsey Conservation District (RCD) to protect the water 376 quality of Bennett Lake. Runoff from. the parking lot and slope adjacent to Prince of 377 Peace Church had been washing down the hill into Central Park, over the years this 378 developed into an erosion issue that washed sediment into Bennett Lake. The shoreline of 379 Bennett Lake has also experienced significant sloughing, causing damage to the lower 380 path. 381 The first phase was done on the church property. The RCD worked with Prince of Peace 382 to make changes to the way their runoff was handled. The improvements included 383 construction of two rain gardens and filling the erosion gully that has formed between the 384 upper and lower pathways. Volunteers from the Church made the improvements in late 385 summer and will maintain these new features. 386 The second phase was a shoreline restoration project for the portion of Bennett Lake 387 located adjacent to the Prince of Peace improvements. The plan was developed by RCD 388 and City staff coordinated. its implementation. The work was completed by Scout 389 members, family, and friends and the Minnesota Conservations Corps, anon-profit 390 organization. 391 In the spring, Dwayne Stenlund, PWETC commissioner, asked if we had any projects ''392 that an Eagle Scout candidate could. help us out with. He recommended that we use Josh 393 Chamberland to lead this first part ofthis project. Josh put together a work plan to 394 complete the project, organizing tools, food, water, and breaks. He spent hours working 395 through the logistics for the project, visiting the site, looking over the plans, and working 396 out how we would accomplish the work. During the two Saturdays that the work was 397 completed, he coordinated the- volunteers and provided supervision. His volunteers 398 completed the first part of the project; removal of buckthorn on the slope between the 399 upper and lower pathways west of the waterfall and the construction of a wave wall to 400 protect the shoreline. 401 This work was completed in August on two separate Saturdays. On the first day, 30 402 volunteers worked for almost S hours removing the buckthorn on the slope between the 403 two pathways.. The buckthorn was laid out and allowed to dry for three weeks. On the 404 second Saturday, the volunteers worked for 5 hours, constructing a. wave wall along the 405 shoreline out of buckthorn to protect the shoreline to be restored. Throughout the project 406 Josh provided leadership to the workers, ensuring that the work was completed as laid out 407 in the plan. 408 During September, members of the Minnesota Conservation Corps completed the work 409 that Josh started, restoring the shoreline and stabilizing the erosion gully between the 410 upper and lower paths. It is anticipated that additional vegetation will be planted along 411 the shoreline in spring 2009. The wave wall will remain in place until the vegetation on 412 this shoreline is established. 413 City of Roseville 2008 Storm Water Annual Report Page 11 of 14
