Bank stabilization060170 1 of 5 OPERATIONS AND MANAGEMENT PLAN VILLAGE OF BUFFALO GROVE BUFFALO CREEK STREAMBANK STABILIZATION PROJECT – PHASE 3 1.0 OVERVIEW 1.1 Purpose The Village stabilized portions of Buffalo Creek within the Buffalo Grove Golf Course with funds provided by the United States Environmental Protection Agency State and Tribal Assistance Grant (STAG) and the Lake County Stormwater Management Commission (WMB grant). The funding agencies require a monitoring and maintenance plan as part of the project. Areas disturbed by the installation of the streambank protection project were planted with native vegetation. These plants help stabilize the streambank and provide wildlife habitat. The long-term management and maintenance of the rock toe and native plants are essential for long-term performance of the project. 1.2 Responsible Parties The Village of Buffalo Grove is responsible for the management of the streambank stabilization areas. The Village may elect to contract with other firms/organizations certain maintenance/monitoring services to ensure proper management of the area. 1.3 Record Keeping Separate and distinct records shall be maintained by the Village for all tasks performed associated with this plan. The records shall include the dates of maintenance visits and the specific work performed. 1.4 Budget Maintenance and replacement costs need to be a part of the Village’s budget. Frequent maintenance program work execution will lead to less frequent and less costly long-term maintenance and repair, possibly requiring replacement. The maintenance provisions of this plan may need to be adjusted based on experience recorded over the initial period of occupancy. 060170 2 of 5 1.5 Interpretation as to Requirements Under This Management Plan Parts of this Management Plan are required under the Village’s Watershed Development Ordinance. Therefore, the interpretation of the maintenance requirements set forth in this Management Plan shall be interpreted on the basis of the intent and requirements of said Ordinance. Specific areas of concern are identified on the Construction Plans. 2.0 STRUCTURES Structures associated with the streambank stabilization project include storm outfalls, storm sewer pipes, and stone toe along the streambank. It is recommended that these structures be inspected twice per year. An inspection checklist is provided below. If any problems are noted, then the repair or replacement of the structure may be warranted. This may require consultation with a Professional Engineer to determine the types of repair or replacement options. 2.1 General - ____ Litter and debris, remove ____ Accumulated sediment, shall be disposed of properly, along with any wastes generated during maintenance operations 2.2 Storm Structures – Pipes/Outfalls ____ Debris blockages, remove ____ Separation of joints, repair ____ Cracks, breaks, or deterioration of concrete, repair ____ Differential settlement, repair ____ Scour and erosion, repair and reseed ____ Damage by debris, ice, or freezing, repair Streambank ____ Debris blockages, remove ____ Erosion, repair ____ Undermining, repair ____ Damage or deterioration, repair 3.0 VEGETATION This section describes the monitoring and management of vegetation within the streambank stabilization project area. Disturbed streambank areas were restored with native vegetation. 060170 3 of 5 3.1 Monitoring Semi-annual monitoring, to be performed in May/June and September, is recommended. Perform a meander survey of each vegetative community. Record all species encountered. Make qualitative observations such as bare spots, species composition (including percent cover), herbivory, presence/location of weedy species, and erosion problems. Report on condition of any native woody live plant material. Record any fauna observed. Take representative photographs. Establish permanent photograph locations so photographs can be reviewed over time. 3.2 Management, Prairie Plants The following text provides a general schedule for management tasks for the establishment of a wet-to-mesic prairie plant community. The actual schedule may vary based on the conditions in any given year and recommendations from personnel familiar with natural areas management. 3.2.1 Typical First Year Management Actions To prevent weed seed development, mow the naturalized areas to a height of 6-8 inches when the vegetation reaches 12 inches approximately 2-to-4 times. Mowing (including weed whipping) shall take place prior to or when non-native and weedy species are flowering so as to prevent seed set. Prevent clippings from smothering native plant seedlings. Cut no more than 4-6 inches to help limit excess clippings. Control undesirable plant species, when present in small quantities, by hand pulling prior to the development and maturity of the plant. Hand removal shall include the removal of all aboveground and belowground stems, roots, and flower masses prior to development of the seeds. For larger areas of non-native or weed species, apply herbicide (as appropriate) to the weedy species by a licensed herbicide applicator that has obtained the proper permits. Do not use herbicides that can harm aquatic organisms. Spot herbicide applications are preferred, either by backpack spray treatments or hand wicking. Consult with natural areas management specialist. Re-plant barren areas as directed by natural areas specialist. Assess need for control of nuisance wildlife (e.g., Canada geese) and coordinate with wildlife agencies for appropriate action(s). 060170 4 of 5 3.2.2 Typical Second Year Management Actions When weed species are present, mow naturalized area to a height of 12 inches. This may occur 2-4 times. Mowing (including weed whipping) shall take place prior to or when non- native and weedy species are flowering so as to prevent seed set. Prevent clippings from smothering native plant seedlings. Cut no more than 4-6 inches to help limit excess clippings. Control of undesirable plant species is likely to consist of herbicide application. Apply herbicide (as appropriate) to the weedy species at the preferred time by a licensed herbicide applicator that has the proper permits. Do not use herbicides that can harm aquatic organisms. Spot herbicide applications are preferred, either by backpack spray treatments or hand wicking. Consult with natural areas management specialist. Re-plant barren areas as directed by natural areas specialist. Assess need for control of nuisance wildlife (e.g., Canada geese) and coordinate with wildlife agencies for appropriate action(s). 3.2.3 Typical Third Year and Beyond Management Actions Undesirable plant species will be controlled (as necessary) by mowing (including weed whipping), hand pulling, or selective herbicide application. At the end of the third growing season, prescribed fire may be introduced if fuel is available. Use personnel familiar with prescribed burns. Obtain necessary permits. Prepare a burn plan. Notify nearby property owners, police, and fire departments. Prescribed burning is typically done between November 1 and April 30. For subsequent prescribed burns, consult with a natural areas specialist for timing (fall or spring burn?, how often to burn (variable between 3-10 years)?) and location (what areas to burn?, what areas to remain as refugia?) of future prescribed burns. If burning is not practical, conduct late winter/early spring mowing with removal of hay. 3.3 Management, Non-Native or Undesirable Woody Vegetation This section describes the selective cutting and disposal of non-native or undesirable woody species. A. Use personnel familiar with identification of plant materials to be removed and native species to remain. Use licensed herbicide applicator for applying herbicides to stumps. B. Cut woody stems to within two inches or less of ground surface. If moved off-site, dispose of brush properly and do not spread seeds/berries of invasive plants to new areas. If on-site brush piles are created, place in open areas away from canopy branches. Brush piles may be used for wildlife enhancement or burned at later date in accordance with burn plan. 060170 5 of 5 C. Apply herbicide to stump. 060170 1 of 6 FINAL PROJECT REPORT VILLAGE OF BUFFALO GROVE BUFFALO CREEK STREAMBANK STABILIZATION PROJECT – PHASE 3 1.0 PROJECT ACCOMPLISHMENTS The Village of Buffalo Grove stabilized a portion of Buffalo Creek and an unnamed tributary to Buffalo Creek within the Buffalo Grove Golf Course. For Phase 3, the Village is stabilized 1,300 linear feet of eroding streambanks with a rock toe and native prairie plants. The project is protecting existing infrastructure (bridges, storm sewer outfalls, and other utilities) from erosive forces. It also reduced the amount of silts and sediments entering the stream and enhanced aquatic habitat. The small riparian buffer should help improve water quality by filtering some of the excess turf management chemicals (e.g., fertilizers, etc.). Changes from the initial grant application included the addition of 870 linear feet of streambank stabilization and replacing vegetated geogrid with rock toe with native plants. The change in streambank stabilization technique was due to the ability to slope back the bank flatter than originally thought was available. 2.0 PROJECT SCHEDULE Intergovernmental Agreement December 31, 2007 Clean Water Act Permit (Corps of Engineers) January 22, 2009 Watershed Development Permit (SMC) January 29, 2009 Begin Work March 2009 Complete Work November 2009 060170 2 of 6 3.0 PROJECT COST SUMMARY Expenses Village Labor $33,821.37 Village Equipment $ 9,629.08 Materials $22,502.77 Consultant Fee (Design/Const Obs) $ 8,500.00 Permit Fees $ 1,200.00 $75,653.22 Reimbursements USEPA – STAG $35,200.00 SMC – WMB $ 8,000.00 Village Share $32,453.22 060170 3 of 6 4.0 POST-CONSTRUCTION PHOTOGRAPHS Looking upstream at upper limits, unnamed tributary to Buffalo Creek.

The project is protecting existing infrastructure (bridge, sidewalk, bike path, storm sewer outfalls, and other utilities) from erosive forces. It also reduced the amount of silts and sediments entering the stream and enhanced aquatic habitat. At the Thompson Boulevard reach, three storm sewer outlet areas were stabilized with riprap. An additional 220 linear feet of streambank were stabilized using bioengineering with rock toe. At Weiland Road, 120 linear feet of streambank was stabilized with gabion baskets. An additional 120 linear feet was stabilized using bioengineering with rock toe. A storm sewer was extended to Aptakisic Creek to solve the eroded gully problem. Rock riprap was placed around the new outfall and a riffle structure installed in front of the Marvins Way culvert. All disturbed streambank areas were stabilized with native vegetation. Willow cuttings were installed along 36 linear feet of gabion baskets. There were some minor changes to the original project drawings. An additional 60 feet of gabion baskets and an additional 40 feet of rock toe were installed to protect the steep streambanks. Also, the riffle structure was installed as a grade control structure to prevent downcutting of the stream. 2.0 PROJECT SCHEDULE Intergovernmental Agreement December 4, 2007 Clean Water Act Permit (Corps of Engineers) February 10, 2009 Watershed Development Permit (SMC) February 18, 2009 Begin Work July 2009 Complete Work November 2009 071765.40 2 of 5 3.0 PROJECT COST SUMMARY Expenses Village Labor $49,405.36 Village Equipment $26,734.75 Materials $15,628.55 Consultant Fee (Design/Const Obs) $ 9,800.00 Permit Fees $ 1,200.00 $102,768.66 Reimbursements USEPA – STAG $25,000.00 SMC – WMB $ 7,500.00 Village Share $70,268.66 071765.40 3 of 5 4.0 POST-CONSTRUCTION PHOTOGRAPHS Thompson Blvd segment – stabilization at two storm outfalls.
