1 FISH HATCHERY PARK JOHNSON CREEK HABITAT RESTORATION Project Funding Request: $612,780 Organization: Contact Name: Alliance of Rouge Community (ARC) Brandy Siedlaczek Chairperson Michigan Avenue, Suite 126 Canton, MI (734) Project Location: Northville, Michigan Wayne County Congressional Districts: M11 Project Duration: PROJECT ABSTRACT The Rouge River watershed is a designated AOC under the Great Lakes Water Quality Agreement (GLWQA), and has three Beneficial Use Impairments (BUIs) associated with fish and wildlife habitat: Degraded Fish and Wildlife Populations, Degradation of Benthos, Loss of Fish and Wildlife Habitat. Rouge River Advisory Council (RRAC), the Public Advisory Council (PAC) for the Rouge AOC, finalized a list of projects that need to be completed in order to remove the habitat BUIs in March As part of that list, habitat restoration on Johnson Creek at Fish Hatchery Park was considered as having significant impact on the removal of the BUIs. The Fish Hatchery Park Habitat Restoration project will result in restoration of 400 feet of shoreline and riparian habitat. PROBLEM STATEMENT Alliance of Rouge Community (ARC) is requesting grant funding for Rouge River Area of Concern (AOC) Northville Habitat Restoration Projects as part of its effort to delist the AOC. The Rouge River watershed is a designated AOC under the Great Lakes Water Quality Agreement (GLWQA), and has three Beneficial Use Impairments (BUIs) associated with fish and wildlife habitat: Degraded Fish and Wildlife Populations, Degradation of Benthos, Loss of Fish and Wildlife Habitat. During the last century, tributaries of the Rouge River have suffered from declining water quality, loss and impairment of aquatic habitat, and increased frequency and magnitude of peak flood flows, primarily due to increasing urbanization within the watershed. The flat river slope and the meandering channel could not pass the large flows associated with major precipitation events. Upstream urbanization continued to exacerbate this problem due to increased amounts of impervious surfaces culminating in floods within downstream local communities. Water quality in recent years, though, has improved since 1992 thanks to the federally-funded Rouge Project. For example, 89 of the 127 miles of the larger streams and tributaries in the watershed are now free from public health threats associated with uncontrolled combined sewer overflow discharges. Water quality improvement is exhibited by

2 increased dissolved oxygen levels needed to sustain fish and aquatic life. Increased populations and diversity of benthos, fish and wildlife have been measured along the river since Also, the U.S. EPA Office of Inspector General declared the Rouge Project a blueprint for success (EPA OIG report number 2002-P-00012). The ARC is the Rouge River Public Advisory (PAC) fiduciary and coordinating organization. Many of the previously completed reports [Ex: Habitat Delisting Targets (2008), Rouge River Delisting Strategy (2012), Upper Rouge Delisting Strategy (2012), and Rouge River BUI Report Card (2013)] listed project types, in addition to specific projects, that needed to be completed in the watershed in order to remove the Habitat BUIs and delist the AOC. The EPA, MDEQ, MDNR, RRAC, and ARC began facilitating the development of the formal list for removal of the Habitat BUIs in This work resulted in the development of a final Rouge AOC Habitat list that was submitted in March The Fish Hatchery Park Habitat Restoration project on Johnson Creek is one of the priority projects on that list due its potential to address the Degraded Fish and Wildlife Populations and Loss of Fish and Wildlife Habitat BUIs. Relevance to Existing Restoration Plans and Priorities - The proposed project responds directly to multiple plans and priorities within the Rouge River AOC: The Rouge RAP Advisory Council s 2016 Rouge River Remedial Action Plan Habitat Projects List identifies these activities as a top priority for delisting the Rouge River AOC. The Rouge River Watershed Management Plan, prepared by the ARC supports river and lake restoration as a key elements in the watershed restoration. Activities respond to the Great Lakes Regional Collaboration Strategy focus on Riverine Habitats and Related Riparian Areas and its long-term goals including conservation of rivers and sustaining native/ migratory fish and aquatic biota/ wildlife. Rouge River Watershed Management Plan Northville Parks and Recreation Master Plan Fish and Wildlife habitat associated with Johnson Creek have been lost and impacted by sedimentation, loss or conversion of riparian vegetation, and streambank armoring with concrete and concrete rubble, reducing its viability as a cold water fishery; the only remaining cold water fishery in the Rouge River. A spring-fed pond, which flows into Johnson Creek, has been degraded by sediment-laden stormwater runoff from the unimproved parking lot at Fish Hatchery Park. The resulting sediment has been deposited into the pond to a point where it is less than 18 inches deep. This sediment escapes from the pond through the outlet structure and is impairing the stream bottom habitat in Johnson Creek. In addition, the earthen wall separating the pond from Johnson Creek is beginning to fail. In time, the wall will collapse which will eliminate the potential cleansing properties of the pond and transfer the accumulated sediment into the creek. Lastly, the earthen wall is hardened on the Johnson Creek side by a poured concrete wall. Streambanks in the park have been impacted by the removal of native vegetation and historic placement of concrete rubble. Fish Hatchery Park is the only public access point to Johnson Creek. The park was once a federal registered fish hatchery facility the first in the nation. The community would like to celebrate the history of the park by restoring habitat while creating an environmental education opportunity for its residents. To address the ecosystem issues, the following improvements are proposed: 1. Remove accumulated sediment in the pond to create a deeper pool and add woody debris for fish habitat;

3 2. Modify the outlet of the pond to create a fish passage channel between the pond and the creek; 3. Stabilize and naturalize the earthen wall between the pond and the creek; and 4. Stabilize and natural streambanks. In addition, the City will replace the unimproved parking lot and drain the runoff to rain gardens or bioswales in order to improve the quality of runoff to the pond and Johnson Creek. These improvements will reduce the amount of sediment, nutrients, and other pollutants delivered to Johnson Creek, pollutants that impair aquatic habitat and reduce the productivity of fish and wildlife populations. RESTORATION OUTPUTS AND OUTCOMES The Johnson Creek Restoration project will produce the following outputs and outcomes: Outputs Naturalize 400 feet of streambank Remove 120 tons of concrete rubble Plant 30 native riparian trees (3 caliper) Connect 0.6 acres of backwater habitat (the pond) to Johnson Creek Restore 0.2 acres of riparian habitat Reduce sediment loading to Johnson Creek by up to 25 tons per year Outcomes: More diverse and intact riparian habitat Restored backwater habitat function (the pond) as wildlife and fish nursery habitat Greater wildlife diversity and productivity Greater fish productivity Aid in the removal of two Rouge River AOC BUIs: Loss of Fish and Wildlife Habitat and Degradation of Fish and Wildlife Populations LONG-TERM MAINTAINENCE The City of Northville and its partners within the Alliance of Rouge Communities are committed to the long-term sustainability of this project. Though the project will be designed as a sustainable water resource project with low maintenance requirements, long-term care and maintenance will be integrated. The City of Northville Parks and Recreation Department manages Fish Hatchery Park and conducts routine maintenance to maintain the park. A management plan will be developed in cooperation with the Parks and Recreation Department as part of project engineering. PROPOSED WORK The ARC proposes the following task summaries in order to complete the Rouge River AOC Fish Hatchery Park Habitat Restoration project on Johnson Creek. Task 1. Grant Reporting/Administration/Public Outreach Overall Grant/Projects This task includes the following elements associated with the overall grant and project:

4 Perform Grant Management Activities - Grant management services and assure compliance with terms and conditions of the grant will be provided. EAGL Reporting - The Environmental Accomplishments in the Great Lakes (EAGL) semi-annual reporting will be prepared and submitted. Coordinate with Partners Coordination between partners and stakeholders in the project. Throughout the process, active participation will be fostered among the stakeholders. Public Outreach The ARC will reach out to the public to inform them of the proposed activities and to obtain input. There will a focused workshop for the interested public. The ARC will be posting information related to the all projects under this grant on the ARC web site and informational flyers will be distributed to interested organizations and the public at large. Final Report A comprehensive final report summarizing all the activities conducted and outcomes achieved will be completed in draft form and submitted for review. Comments received will be incorporated in to a final version for submittal. Deliverables: Reporting and public meeting(s) Task 2. Preliminary Engineering and Field Investigation For the Johnson Creek Habitat Restoration project, background data will be collected and reviewed. This information will be used as the base map for the design and will form the basis of the design decisions. This work will be completed primarily by the selected engineering consultant with assistance from Northville. The following data collection needs will be completed in order to develop the design, allow for project permitting and provide baseline data for construction. Health and Safety Plan (HASP) Development A site specific health and safety plan will be developed for the project. Potential hazards will be identified, and steps will be outlined to reduce risk to employees and visitors to the site. The HASP will also detail steps for emergency response, including directions and a map to the nearest emergency room/urgent care. QAPP Development - In accordance with federal requirements all environmental measurements undertaken in support of this project will be required to be conducted under a formal quality management protocol. A project specific Quality Assurance Project Plan (QAPP) will be prepared and submitted for review and approval prior to beginning any data collection activities. Primary data gathering will include field information for design and post measurements of metric outputs. Topographic Survey A survey of the ground surface elevation will be conducted. The surveys will include the location of existing or abandoned structures and utilities. Property boundaries will be established from recorded legal description. Flagged wetland boundaries will also be surveyed. Hydrologic and Hydraulic Analysis

5 The frequency, stage, and velocity of flows in Johnson Creek are important factors in the design of the restoration plan. Johnson Creek is an ungagged stream. A long-term flow record does not exist. Flow frequencies and magnitude will be estimated using numerical runoff calculations for small ungagged watersheds. A hydraulic model will be developed to analyze flow stage, flow velocity, and shear stress within the channel. These model outputs will in turn be used to develop design criteria. Wetland Assessment/Riparian Vegetation Mapping - Professional wetland scientists and ecologists will conduct a field survey of the site. The survey will determine the location and type of wetlands present, and map riparian vegetation communities within 20 feet of the channel along the north side. The jurisdictional limits of wetlands will be flagged for surveying during the topographic surveying. Delineation of wetland boundaries is necessary to evaluate and quantify project impacts. Geotechnical Investigation Streambank soils will be field characterized to qualitatively determine composition (clay, silt, sand, gravel, organic) and stratification. This information will inform design decision making for streambank grading and stabilization methods. Sediment Analysis Sediment samples will be collected from within the pond for waste characterization and determining disposal requirements. The samples will be analyzed based on the State of Michigan protocol for dredge characterization which includes Metals, Volatile and Semi-Volatile compounds, and PCB scans. TCLP will be run on samples that laboratory results indicate detectable levels of interest within the dredging protocol. Threatened & Endangered Species (T&E) - Since all federal agency grant programs require at least a programmatic environmental assessment that must consider potential impacts to federally and state-listed T&E plant and animal species, T&E information will be collected. The Michigan Natural Features Inventory (MNFI) maintains a continuously updated natural heritage database that provides a comprehensive source of existing data on Michigan's endangered and threatened plant and animal species. Records in the database indicate that a qualified observer has documented the presence of T&E species within a specified distance (usually 1.5 miles). The absence of records in the database within the vicinity of a project site does not preclude the potential presence of T&E species. Furthermore, the U.S. Fish and Wildlife Service (USFWS) publishes a county distribution list of federally listed threatened, endangered, proposed, and candidate species. This list indicates the potential for T&E species to be present within the county where a project is located (or neighboring counties). However, unlike the MNFI database, this list does not necessarily indicate documented presence of T&E species. The project area (i.e., potential disturbance limits) will be visited by qualified ecologists and evaluated for suitable T&E species habitat and potential presence of listed species that occur within a 1.5-mile radius of the project site (based on the MNFI database and the USFWS Northville species list). Only those T&E species that have the potential to be impacted by the proposed project, based on physical site characteristics, will be targeted for site-specific field surveys. Deliverables: T&E Summary HASP, Base Map, Geotechnical and Soil Characterization Summary, Wetland Delineation Report, Task 3. Design/Permitting This task will include hydraulic modeling as required, development of construction design plans, technical specifications, and construction cost estimating.

6 During the design phase of the project, plans will be advanced to 30% design drawings, with additional engineering, planning, design refinement/modifications, stakeholder collaboration, and Technical Team review and feedback. Following this review, the design drawings produced will be advanced to 50% design for review and then to 95%. Final plans and specifications will be developed following the last review. The design will take into account the technical needs as follows: Streambank Naturalization Plans, sections, details, and specifications will be developed for removal of existing vegetation and concrete rubble; grading of streambanks to a stable angle of repose; and establishment of native riparian vegetation. Trees removed from the streambank will be salvaged and used to create large woody debris structures in the stream. Pond (Backwater) Restoration Plans, sections, details, and specifications will be developed for restoration of the backwater pond, including removal and disposal of sediment, repair/fortification of the earthen dike, removal of the concrete seawall and naturalization of the shoreline along Johnson Creek. Trees salvaged from site clearing will be used to create loafing logs in the pond for waterfowl and turtles, and structure for fish. The pond outlet will be replaced with a rock ramp constructed with cobble and boulders to allow fish to move freely between Johnson Creek and the pond. Long-term Management Plan A long-term management plan will be prepared during the design phase, to coordinate and plan management activities needed to ensure project sustainability. Additionally, this task will include permitting services with the intended purpose of obtaining the Joint Permit from the MDEQ. The following activities will be completed as part of this task: Prepare a pre-application meeting package with pre-application meeting fee and work to schedule a site meeting and project review meeting with MDEQ Division staff. The purpose of a formal pre-application meeting is to review statutory permitting requirements. A Joint Application for Permit will be completed, including all necessary attachments. Quantities of cuts and fills in wetlands, streams, and floodplains will be calculated from the design drawings and tabulated. Basis of Design Report detailing the final design will be prepared (Supporting data, analyses, computations, and modeling will be presented in a concise format. Periodic communication with District permitting staff will allow dialogue on design before the Joint Permit Application is submitted. This will include project partner meetings which will allow for exchange of ideas, discussion of concepts and concerns culminating in the development of a prudent, feasible, and permittable project design upon completion. This process will help ensure that a permittable project is designed and will facilitate the permitting process. Deliverables: MDEQ Permit and 95% Plans & Technical Specifications Task 4. Contract Documents and Contractor Selection The design plans and technical specifications developed under Task 3 for will be finalized in the contract bid documents. A Northville plan approval package will be prepared and submitted to the planning commission for approval. All contractual front end specifications will be developed and all funding grant requirements will be addressed and incorporated (signage, etc.).

7 The contractor bidding processes will be administered, including issuing the bid package, and selection of the construction contractor, and contracting with the chosen contractor. The Engineer of Record will assist with the bidding processes by conducting the pre-bid meetings, answering questions/providing clarifications to bidders, drafting addendum as needed, evaluating bids submitted and providing a recommendation for contractor selection. This task will include the following subtasks to aid the in the procurement of a qualified contractor for each construction project. Prepare a Pre-Bid Meeting agenda; Prepare for a Pre-Bid Meeting, to include a site field trip; Respond to questions for clarification on the contract documents; Prepare, as needed, Addendum for the bid process; Review/analysis of Contractor s bids; Provide Engineer s Recommendation for contractor selection; and Budget vs. Bid analysis and site recommendations; Deliverables: Contract Contract Bid Documents, Advertisement for Bid, Bid Tabulation, and Construction Contractor Task 5. Construction/Construction Oversight The contractor selected will complete the construction in accordance with the construction documents. Construction oversight will be provided during construction. Quantitative and qualitative measures will be employed to track progress in both project implementation and to assess project results. Field Engineering Oversight Services This will include all functions and activities necessary to provide the oversight necessary so that all materials provided and work performed is in conformance with the project plans and specifications.
