This proposal was prepared with the help of our subconsultant, Anderson Consulting Engineers (ACE) who brings their considerable experience with hydraulic modeling, analysis, and Conditional Letter of Map Revision (CLOMR) submittals and will ensure the analysis fully meets City and County requirements. Some of these requirements include the new City floodplain modeling report guidelines and the conversion of all prior work into the more recent NAVD88 vertical datum. The proposal includes a budget for King Surveyors to supplement available topographic data as well the fees for the City, County, and FEMA review. Please note that the attached Scope of Work assumes that work will be conducted on a time and material basis with a not-to-exceed budget. Based on recent discussions about potentially increasing modeling efforts, an optional task is included for the development of a 2-dimensional model for your consideration. As in the past, level of efforts and costs associated with any of the tasks can be modified based on input from the project team. We sincerely hope the attached proposal meets your current needs. Please review the enclosed materials and do not hesitate to contact me (303-477-0660) if you have any questions or require any additional information. Thank you for the opportunity to conduct this work. Sincerely, BIOHABITATS, INC. _______________________________ Claudia Browne Contract Manager Kingfisher Point Ecological Restoration Project Final Design and Permitting Proposal Restore the Earth & Inspire Ecological Stewardship 1 06/06/2016 SCOPE OF WORK 1. Biohabitats will develop the final design and produce design/build construction documents for the ecological restoration of the Kingfisher Point Natural Area, covering the Poudre River channel and floodplain on Natural Areas property from Lemay Avenue to Timberline Road, including edge enhancement along Gadwall Pond, and wetland creation in nearby ponds using excess excavated material. The restoration design will be based on the concept dated April 22, 2015, which was developed through the collaboration of Biohabitats and Natural Areas staff. 2. In addition, Biohabitats will prepare and submit a permit application for US Corps of Engineers 404 wetland permitting, prepare and submit a request for ESA clearance from US Fish and Wildlife Service, and, working with our subconsultant Anderson Consulting Engineers (ACE), prepare and submit a Conditional Letter of Map Revision (CLOMR) for City, County and Federal review. WORK PLAN TASK 1 PROJECT KICKOFF, COORDINATION MEETINGS, DATA REVIEW, & FIELD ASSESSMENT a. Biohabitats will meet with Natural Areas staff for a kick-off meeting to review this scope and discuss actions that have occurred since the concept plan. The meeting will cover:  project tasks and schedule  updates on property issues, project limits, and site access  shared understanding of the concept design elements and the overall approach  roles, expectations, and communication  integration of diversion dam and ditch modifications  existing information that may be needed for permitting  any remaining data gaps and how to fill them  finalization of design objectives and project outcomes b. Biohabitats will prepare a preliminary schedule of project phases (i.e., design, permitting, and construction) to reflect updated conditions and understanding. As part of this task, c. Biohabitats will review existing data and collect any remaining readily-available information that is needed for design, including: flood maps, modeling & documentation; available ESA documentation; and; historical documents and precedents related to potential visitor experience features. d. Biohabitats will meet with City Stormwater staff to introduce them to the project and solicit any relevant input that they may have. We will also discuss the floodplain permitting process and expectations. Kingfisher Point Ecological Restoration Project Final Design and Permitting Proposal Restore the Earth & Inspire Ecological Stewardship 2 06/06/2016 e. Biohabitats will complete field work to support design development and permit application preparation. The effort will include wetland delineation within the project area (excluding pond islands). We will look at ground elevations, vegetation, locations of existing key features, indicators of wetland hydrology, channel and floodplain conditions, and potential locations for visitor experience features. Visits to facilitate the calibration and development of the hydraulic model are also included. Deliverable will be the revised project phasing schedule. TASK 2 DESIGN DEVELOPMENT a. Biohabitats, with our subconsultant Anderson Consulting Engineers, will complete a hydraulic analysis of the project reach. Based on lessons learned from previous projects, this task will include analyses of more frequent, lower discharge flow events (i.e. 5-year, 2-year, average annual, etc.). This will allow for assessment of project impacts with respect to bank overtopping, trail inundation, and other thresholds for the ecological design. To facilitate the design process and creation of additional cross sections, more detailed survey data will be collected to refine the LIDAR data at critical design locations. Conceptual hydraulic evaluation of proposed improvements and revised proposed project condition hydraulic analysis are also included in the design process. b. Based on our field assessment, data review, and preliminary hydraulic modeling results, Biohabitats will develop the key design elements, such as channel alignment, channel profile and cross section, floodplain grading extent and elevations, and species composition and configuration for planting design. c. The Biohabitats team will also develop the design for a visitor experience feature. We will first create up to 3 schematic-level alternatives, explored in plan, section, and perspective. The schematic alternatives will include possible ideas for programming of any activities with appropriate locations such as the Mulberry trailhead. Biohabitats will meet with Natural Areas staff to review alternatives. Once selected, Biohabitats will further explore the preferred (chosen) alternative, which will include research of specific materials/methods and development of preliminary plan and section views. We will submit to Natural Areas the refined concept of the chosen alternative for their review. Any comments generated from this review will be incorporated into the draft plans. d. Biohabitats will develop a draft restoration design and put together a draft design/build plan set based on available aerial photography and existing contour information. We assume that the 2013 LIDAR derived 1-foot contour data from the Risk Map project will be used for the base topography. The Draft Plan will include floodplain and wetland grading elevations, proposed inundation zones, channel regrading and instream features, details for visitor experience feature, bank treatment approaches, Kingfisher Point Ecological Restoration Project Final Design and Permitting Proposal Restore the Earth & Inspire Ecological Stewardship 3 06/06/2016 planting zones, and plant schedules. The Draft Plan set will be developed to a near- final level so that the CLOMR modeling can be developed and submitted using the Draft Plans. e. Biohabitats will develop a design memorandum which will include an opinion of probable construction cost. The cost estimate will be based on the draft plan set. f. Plan-in-Hand. Upon completion of the Draft Plan, Biohabitats will conduct two plan- in-hand meeting sessions with City Natural Areas staff and other participants, as deemed necessary by Natural Areas, to review the Draft Plan and discuss the design, site constraints, and other pertinent considerations. The two sessions are necessary to fully consider all design items, including planting. The City will compile and submit comments on the draft plan following the meeting sessions. Biohabitats will incorporate these comments into the Final Plan in Task 4. Deliverables will be the schematic alternatives and concept of chosen alternative of the visitor experience feature, draft design plans, and design memorandum with opinion of probable construction cost. TASK 3 PERMITTING & CLOMR SUBMITTAL a. Anderson Consulting Engineers, will complete a hydraulic analysis of the project reach including Effective, Duplicate Effective, and Corrected Effective Condition Hydraulic Analysis and Existing Pre-Project Condition Hydraulic Analysis. Biohabitats’ and ACE will prepare an hydraulic analysis and floodplain/floodway mapping report for the City and County Flood review and approval in accordance with the recently adopted “City of Ft Collins Floodplain Modeling Report Submittal Guidelines.” (Note if possible revisions to the submittal will be made within the existing budget, but it is difficult to anticipate the level of effort required at this time, and revisions may require a time and materials change order.) Biohabitats and ACE will then prepare a Conditional Letter of Map Revision (CLOMR) with all of the required documentation for submittal to FEMA. (The LOMR process will be included in the Construction phase and completed following completion of the project.) Due to the flood hazard changes anticipated as part of incorporating the RiskMAP data into this study, it is estimated that approximately 30 notification letters and accompanying figures will need to be completed as part of this task, whichwill be a considerable effort. It is noted that the CLOMR submittal fee of $8,250 has been included in the review fees associated with this Scope of Work. b. On behalf of the City of Fort Collins, Biohabitats will fulfill all requirements to secure a §404 permit verification under Nationwide Permit 27 Aquatic Habitat Restoration, Establishment, and Enhancement. The components provided will include the following items:  Wetland delineation of the entire project area, including the pond at Cattail Chorus Natural Area that may receive fill material. (This item is covered under the Field Work Task 1d.) Kingfisher Point Ecological Restoration Project Final Design and Permitting Proposal Restore the Earth & Inspire Ecological Stewardship 4 06/06/2016  A pre-application meeting with the USACE.  Securing a letter of concurrence from the U.S. Fish & Wildlife Service (FWS) that the project area does not support habitat for Federally threatened Preble’s meadow jumping mouse (Zapus hudsonius preblei), Ute lady’s tresses orchid (Spiranthes diluvialis) or the Colorado Butterfly Plant (Gaura neomexicana var. coloradensis).  U.S. Clean Water Act 404 wetland permit application. (The permit submittal will be based on the Draft Plan). c. Once the permit application is submitted to the USACE, we will track the permit review and serve as the primary point of contact for the USACE, available to answer questions and provide clarifications as needed. Comments by regulatory agencies that impact project goals and objectives will be discussed and resolved with the City, and incorporated into the final design plans, as appropriate. d. Completion of a stormwater management plan (SWMP) as part of the design plans. The SWMP will be necessary for eventual submittal of an application to the Colorado Department of Public Health and Environment (CDPHE) for Stormwater Discharges Associated with Construction Activities permit (COR030000), which will be part of the Construction Services phase not covered under this scope of work. e. Prepare and submit a City erosion control report. This task assumes that the City will approve the project with no additional information requests or production of new supporting documentation. If additional material is needed to gain approval, then the scope and fee would need to be amended accordingly. Deliverables will be permit applications and CLOMR submittal. TASK 4 FINAL DESIGN Final Design/Build Plans. We will prepare the Final Plans to a level suitable for design/build by Biohabitats that will be based on the Draft Plans. The Final Plans will incorporate comments received by the City and regulators, as appropriate, and will include plan views, typical details and cross sections, and planting schedules. Biohabitats will also revise the opinion of probable cost estimate for construction based on the Final Plans. Deliverable: Final design/build plan set with revised opinion of probable construction cost. OPTONAL TASK – 2-D HYDRAULIC MODELING AND INUNDATION MAPPING Should the City want to have more refined hydraulic information for the project design and develop inundation mapping for events less than the 100-year, Biohabitas and ACE would utilize HEC-RAS 5.0 to develop a hybrid 1-D in-channel with 2-D overbank models of the project reach. To provide a Kingfisher Point Ecological Restoration Project Final Design and Permitting Proposal Restore the Earth & Inspire Ecological Stewardship 5 06/06/2016 comparison of pre- and proposed project conditions, it is assumed that the 1-D hydraulic models developed during the design process will be modified to incorporate a 2-dimensional mesh in the overbank. The 2013 LiDAR data and supplemental survey collected by King Surveyors, will be utilized to develop the “top of bank interface” between the 1-D in-channel domain and the 2-D overbank modeling domain. This analysis will help identify the existing locations at which water will first begin to spill out of bank and how the water is conveyed once it is in the overbank. It can also help refine the project design with respect to the establishment of threshold elevations for bank overtopping, trail inundation, or other ecological factors. This task assumes that the pre- and proposed project models would be analyzed with up to 6 discharges (ranging from the average annual discharge up to the 100-year discharge) which would be conducted with a quasi-steady state analysis to define inundation limits and other pertinent hydraulic parameters. For display purposes, unsteady state analyses would be conducted for the 10-year and 100-year events using the hydrographs developed as part of the RiskMAP hydrologic analysis. The mapping software associated with HEC-RAS 5.0 would then be utilized to generate mapping for flood inundation limits, velocity magnitude and vectors, and other applicable hydraulic parameters pertinent to the project design for the modeled discharges. SCHEDULE Biohabitats is available to begin work on these tasks within 5 days upon notice-to-proceed. The table below provides a preliminary schedule which will be revised during Task 1 of the project. Description Duration Approx.

ASSUMPTIONS/ LIMITATIONS 1. The design covered in this scope of work will be based on the final restoration concept, dated 04/22/2015 2. This scope of work ends at the completion of final design plans. It does not include any construction services, which will be the project phase that follows final design. When final design is complete, Biohabitats will submit a proposal to the City for construction. 3. Biohabitats’ scope of work does not include an assessment of water rights, property ownership, or other legal issues that may be associated with the project. The City is responsible for confirming that the project is permissible under water law. 4. This scope of work assumes that a FWS concurrence letter for Ute Ladies’-tresses orchid. Colorado Butterfly plant, and Preble’s meadow jumping mouse is sufficient to obtain the 404 permit. If a Biological Assessment or formal FWS consultation is required, the scope and budget would need to be amended accordingly. In addition, this scope of work assumes that Natural Areas staff will provide species information on Ute Ladies’-tresses and Preble’s meadow jumping mouse to help obtain FWS approval of the project. 5. Wetland delineation will not include pond islands since they will not be impacted by the proposed work. 6. This scope of work assumes that the wetland and open water impacts will require a Nationwide Permit 27 Aquatic Habitat Restoration and Enhancement. If, for some unanticipated reason, a different type of permit is required, then the scope and budget Kingfisher Point Ecological Restoration Project Final Design and Permitting Proposal Restore the Earth & Inspire Ecological Stewardship 7 06/06/2016 would need to be amended to include the work necessary to address the additional regulatory issues. 7. Hydraulic modeling and analysis will be limited to the study reach. Sediment transport analysis and modeling are not included. 8. The scope of work does not include identification or remediation of hazardous, toxic or radioactive waste, special-status species surveys, or detailed biological inventories. 9. The Natural Areas Department is responsible for coordinating project-related planning activities with their staff. 10. Alterations in the scope of the project, such as additional design iterations, additional meetings, presentations or exhibit displays, or deliverables other than those explicitly identified in the task descriptions, will be considered change orders and may entail additional charges. 11. This proposal is valid for a period of 60 days, after which it may be renegotiated. ADDITIONAL SERVICES Services in addition to those described above are to be compensated on a Time and Materials basis (unless otherwise noted) per Biohabitats’ contracted rate schedule, attached. Additional services will include (but are not limited to) additional meetings and field visits and major revisions to and/or expansion of scope of services. Whenever practical, changes, additions, or modifications to the scope of services shall be authorized by written change order request; however, the absence of such a written change order shall not act as a bar to payment of fees due Biohabitats, provided the change was in fact approved and ordered by the Client or Owner. Payment Terms INVOICES FOR SERVICES AND/OR EXPENSES DESCRIBED HEREIN ARE DUE AND PAYABLE UPON COMPLETION. All amounts not paid within 35 days shall be subject to a late payment interest charge at the rate of (1.5) percent per month, (eighteen percent APR) from the date of invoice. In the event that Biohabitats does not receive payment within 60 days from the date of the invoice, Biohabitats, after giving seven days written notice to the Client, may suspend or terminate the contract without causing any type of financial or legal penalty or action against Biohabitats by the Client or Owner. Work may commence once the Client has paid in full all amounts due for services rendered and expenses incurred, including interest on past due invoices. This proposal is based on a continuous work process. If the work schedule is delayed and/or the project scope or budget is changed, Biohabitats can provide additional services upon agreement by the Client to pay for additional services fees. Extensive itemized breakdowns of hourly activities or provision of detailed backup for reimbursed expenses for accounting purposes are not a normal procedure; however, at the Client’s request, Biohabitats will provide this service at an hourly rate of $65.00 (sixty-five dollars) per hour.
