City of Fort Collins Water Utilities 700 Wood Street Ft. Collins, CO 80521 RE: REVISED Timberline Road Wetland Mitigation Revegetation Services Biohabitats Proposal No. 11910.01 Dear Mr. Taylor: Thank you for asking Biohabitats to assist the Fort Collins Water Utilities with wetland revegetation at the Timberline Road mitigation site. As we discussed at the January 31, 2011 meeting with Natural Areas, we understand that Water Utilities is seeking assistance to develop and implement a planting plan to meet the requirements of U.S. Army Corps of Engineers Section 404 Permit Number 200380268. Background. To compensate for loss of wetlands during the City's Timberline Road project, 1.36 acres of wetland (0.95 acre of vegetated wetland and 0.41 acre of open water) were authorized as mitigation in 2004. Based on wetland parameters of vegetation, hydrology, and soils determined by a site inspection conducted by Biohabitats on August 17, 2010, the area of vegetated wetland that meet performance standards is currently 0.24 acres. To achieve the total 0.95 acres of wetland mitigation, 0.71 acres of vegetated wetland remains to be created. This letter outlines our proposed scope of work and fee for developing a planting plan and implementing the recommended improvements to achieve the desired mitigation project. Approach. Biohabitats' approach will aim to maximize success of the on -site vegetation by planning for the uncertainties that have been identified since the initial mitigation project. First, the planting plan will be based on a characterization of soils and observed depths to groundwater during field visits in order to integrate salinity, flooding, and other features critical to plant survival. Second, the plan will utilize a mix of plant species with varying tolerances to flooding and salinity. Finally, the wetland planting plan will aim to cover a slightly greater area and higher density than needed to help ensure success in the event of some plant loss. Please note that because the final cost of planting materials and installation cannot be determined until the planting plan is complete, we propose completing the revegetation project in two phases: Phase 1 Planting Plan Development and Phase 2 Implementation, as described below. Phase 1 — Planting Plan Development As shown on the attached Exhibit, there.are 8 wetland areas with low and medium density vegetation that will be the focus of the revegetation plan as discussed in Biohabitats' 2010 wetland report to the USACE. To comply with the Section 404 permit, the planting plan will incorporate 860 willow live stakes and 11 native cottonwood trees along with appropriate wetland plug species. Specific species selection and planting locations will be based on a site visit and data collection as described below, in addition to the information that we have already gathered. 1. Biohabitats will visit the project site to gather more detailed information on soil characteristics, planting locations appropriate for specific species, extent of surface water, depth to groundwater, and invasive species types and distribution. 2. In each of the 8 proposed planting areas and in up to 2 additional locations in existing good quality vegetation, Biohabitats will make soil boreholes using a hand auger, will collect samples for soil texture characterization in the field as well as laboratory analyses, described further below. We anticipate digging each borehole to a depth of approximately 12 to 24 inches. In each borehole, we will observe vertical soil conditions throughout the rooting zone and depth to groundwater. 3. One soil sample from each borehole will be submitted to a local laboratory (e.g., Accutest Laboratory in Wheat Ridge) for general chemistry analyses necessary to help inform plant selection. Example parameters may include alkalinity, pH, phosphorous, nitrogen, organic content, and specific conductance. 4. The soil sampling locations and the targeted revegetation areas will be mapped in GIS and placed on an aerial photograph as the base map for the planting plan. Results of the field and laboratory tests from the successful high vegetation areas and the low vegetation areas will be compared to identify any major differences or possible constraints. 5. We will prepare a draft wetland planting plan and draft construction cost estimate to revegetate the targeted areas and meet the mitigation requirements. At this time, we anticipate that the plan will cover a minimum of 0.72 acres of vegetated wetland, but may extend to up to one acre to help ensure successful cover. 6. A copy of the draft plan will be submitted to the City for review and comment. At the same time as the City's review, we will coordinate with the USACE to ensure their acceptance of the mitigation project. 7. Upon receipt of the City's comments and confirmation from USACE, Biohabitats will produce a final plan along with a construction cost estimate, which we will submit to the City as the Phase 2 cost proposal. Phase 2 -- Implementation • Upon receipt of the City's acceptance of the Phase 2 cost proposal, Biohabitats will initiate implementation of the plan. • We will be fully responsible for ordering plant material and all activities related to installation of the wetland plants. • Biohabitats will prepare a draft letter report to the Corps of Engineers describing the revegetation activities and providing photographs and a map documenting site conditions during and after revegetation. Biohabitats will submit a draft to the City for review. We will then prepare a final version for submittal that incorporates the City's comments. Schedule and Fee We are available to assist the City with this project upon notice to proceed, and anticipate that the field work could be conducted this spring. Our goal would be to conduct the planting during the early part of the growing season, assuming the areas are not flooded, so plants have the optimum period of establishment. Our lump sum fee to conduct Phase 1 of the above scope of work is $7,125.00 as broken out below. Staff Hours Rate Labor$ Project Manager — C. Browne 3 $ 145.00 $ 435.00 Engineer/ Sr Scientist — Li hthiser/Backus/Sortman 46 $ 125.00 $5,750.00 Env Scientist — J. Pfister 10 $ 85.00 $ 850.00 Reimburseables—e.g., Field equipment 1 $ 90.00 $ 90.00 Total Project $7,125.00 Not included in this fee is the cost of the laboratory soil analyses which we expect to complete within a budget of $1,500.00. As noted previously, we will submit the Phase 2 cost proposal after completion of the planting plan. Please contact Mike Lighthiser or me at 303-477-0660 or (cbrowne@biohabitats.com and mlighthiser@biohabitats.com ) if you have any questions or wish to discuss the scope of work in more detail.
