O Coastal PAmo ree Area Type. qt Nmd Banks Identifying nwnbw or 1enw Of x+0001 dmuments Approximately 500tF of bank will be stabilized along the shoreline of Willow Lake. The banks along the shoreline of Duck Island will also be stabilized. Materials used will either be slope paving or dumped rock. The bank area of the Mill River will be impacted slightly during construction. Heavy equipment used while constructing the inlet may compact surrounding vegetation on the bank. All performance standards set forth for bank areas will be met. The physical stability of the banks will improve as they are presently unstable. The water carrying capacity of the Mill River, inlet channel, and Willow Lake will remain the same. Groundwater and surface 'water quality will actually improve as erosion will be ,decreased significantly. All altered areas of bank where wetland vegetation will be altered will be replaced with indigenous plant species. Much of the bank area to be disturbed adjacent to Willow Lake consists of little or no wetland vegetation. 20 of eroding banks on each side of the backwater area of the inlet channel will be filled and piped for the purposes of constructing the access road.

During these construction activities all proper erosion and sediment control measures will be installed to manage erosion problems and to trap sediment from entering stream waters or wetlands. These measures will protect the wetlands as well as water quality. After construction is completed all areas will be stabilized and re- vegetated with indigenous plant species. Most areas of bordering vegetation wetland will not be lost, only altered slightly during construction, with the exception of approximately 600SF of DFW that will be filled for the construction of the access road. Individual wetland species that may be lost along the shoreline of Willow Lake during bank stabilization will be replaced elsewhere along the shoreline of Willow Lake.

PWdocum*nts Stream water from the Mill River will be divertdd away from the inlet channel to Willow Lake, and the Lake will Figures 3, 5 be drained when the dam is breached. Conventional dredg- 6, 8 -14 ing equipment will excavate at a maximum approximately 9,000 cy. yds. of sediment from the lake bottom. The dredged material will be transported to the containment area via the proposed access road. Approximately 45'± of the inlet channel adjacent to the Mill River will be piped. Approximately 20' of a backwater area of the in- let channel will be piped for the construction of the access road. Fish will either move downstream into the ill River when the dam is breached or will stay behind and be reclaimed. Other wildlife such as ducks will be moved to the backwater area from the Mill River also located in the Park. 91 Part V.- Addltional InformaKon for a Department of th Per it ' - COEAppricatkxn t �It��iean "Jer loop of adjacent Mill River 2. now fimrtinning as an int channel (to be provided by COE) (Name of waterway) 3.

The present eutro- phication of the lake and associated shoreline erosion problems have rendered the 4 acre± waterbody almost unusable for pedal boats and fishing. Aggravated shoreline erosion has contributed to reduced water quality as well as to the loss of significant trees by root exposure and subsequent rot. Excessive nutrients delivered to Willow Lake from upstream and in -lake sources has resulted in accelerated macrophytic and algal growths. The proposed implementation plan will remove in- lake and shoreline nutrient contributions, and will divert upstream out -of -lake nutrient sources. The prinicipal actions associated with the lake restoration program involve the dredging of about 9,000 Cy, at a maximum, of nutrient laden but otherwise clean hydrosoils, and their ultimate disposal within the park confines into a designed containment area. Another portion of the proposed action involves the construction of 500! LF of either slope paving or dumped rocks to control shoreline erosion and 800! LF of erosion protection to preserve the outer limits of an eroded alluvial island within the lake which is a bird sanctuary. Finally, lake level controls at the inlet and the outlet are proposed to divert nutrients from upstream sources during storms and draw the lake down for occasional maintenance. Finally, swaled basins, grading, and landscaping are proposed to limit storm water pollutional effects within the park limits.
