Building a Strategic Plan for the Mill River Greenway by The Conway School

BUILDING A STRATEGIC PLAN FOR THE MILL RIVER GREENWAY The Mill River Greenway would connect communities living along the Mill River to the area's rich history, recreational land, ecological wonders, bike paths, and hiking trails. It would build community engagement, get people outside, and provide historic and cultural educational opportunities. This document seeks to inspire the foundation of a strategic plan for the Mill River Greenway by identifying opportunities for ecological and human corridors and considering how the two intersect. Context sensitive solutions and broad recommendations are made for the Mill River Greenway Initiative to continue their success in creating the Mill River Greenway.

The Conway School is the only institution of its kind in North America. Its focus is sustainable landscape planning and design and its graduates are awarded a Master of Science in Ecological Design degree. Each year, through its accredited, ten-month graduate program students from diverse backgrounds are immersed in a range of real-world design projects, ranging from sites to cities to regions. Graduates play significant professional roles in various aspects of landscape planning and design.

EXECUTIVE SUMMARY A greenway that runs along the historic 15-mile Mill River and connects the eight villages of Goshen, Williamsburg, Haydenville, Leeds, Florence, Bay State, Northampton, and Easthampton provides opportunities for people to reconnect to the rich historical and ecological resources of the Mill River. Since 2009, the Mill River Greenway Initiative has gathered research data including existing maps, information about projects and initiatives, subcommittee findings, and feasibility studies to begin the process of implementing the Mill River Greenway. The Conway School was commissioned to compile the data,

collect community feedback, and then formulate a framework for moving the greenway forward. The process of the Conway School project started with creating a data gap analysis to show missing data components for each section of the greenway. Through organizing all existing data by village, a methodology was devised which identified potential ecological and human corridors for the greenway. Based on existing site conditions, cultural resources and surrounding ecology, summary maps were developed to delineate areas favorable for ecological and human connections. The size of the greenway, spanning 15 miles over eight villages, presented

some challenges for this project. In addition, the lack of site specific data also limited the ability to provide site-specific solutions. To address this situation, context sensitive solutions, or implementation options based on specific sets of existing conditions, were identified for both human access and ecological restoration. These can be used at a site scale after more detailed site analysis is completed. To move the Mill River Greenway forward, broad recommendations are provided that address the need for organizational structure, partnerships, and stewardship of this valuable resource.

The Mill River Greenway would stretch 15 miles passing through 8 villages, interconnecting diverse ecological resources with the rich historic heritage of the Mill River.

Building a Strategic Plan for the Mill River Greenway

INTRODUCTION Bringing people back to the river Greenways, while varying in definition and form, provide connections for people and nature within the landscape. They can be composed of trails, bike paths, wetlands, waterways or woodlands, or a combination of all these. They can be one contiguous path or a network of trails. Ultimately, greenways weave together the paths of people, plants, wildlife and water.

The Mill River Greenway Initiative (MRGI) is a group of community members from eight villages (Goshen, Williamsburg, Haydenville, Leeds, Florence, Bay State, Northampton and Easthampton) who are envisioning a 15-mile greenway along the historic Mill River. Understanding the rich history of the river, MRGI defines The Mill River Greenway as a nonmotorized network of pedestrian paths, bikeways, sidewalks, and recreational areas that bring people back to the river. This greenway would enhance community engagement,

highlight cultural and historic features, restore ecological systems, and link open space and other recreational opportunities.

From acting as a vegetated buffer to protect natural habitats to reducing the impacts of flooding, greenways can be designed to sustain the natural landscape. At the same time, they encourage connections between communities, historic sites, and recreational opportunities that can support a regionâ&#x20AC;&#x2122;s environmental, economic, and social health.

The Mill River Greenway is not one single continuous path but rather a network of trails consisting of scenic lookouts, bike paths, hiking trails, historic sites, and recreational facilities.

Building a Strategic Plan for the Mill River Greenway

HIGHLIGHT: MRGI In 2009, a citizensâ&#x20AC;&#x2122; advocacy group formed with the aim of making good design a central feature in downtown Northampton where the Mill River ran before 1940. Later that year, a dozen Northampton and Williamsburg residents gathered to extend the idea of good design to the whole Mill River. By spring of 2010, MRGI numbered some three dozen members and held bi-monthly meetings, established an agenda to collect archival materials, held community meetings, and worked on a series of projects.

In November 2010, MRGI partnered with Smith Collegeâ&#x20AC;&#x2122;s Center for Environment, Ecological Design, and Sustainability (CEEDS) to begin a partnership that has resulted in a series of research and professional projects. In 2012, three members of MRGI stepped up to volunteer as comoderators: John Sinton, Gaby Immerman, and Neal Bastek. The highlight of that year was a charrette led by faculty and alumni from the Landscape Architecture and Regional Planning Department of the University of Massachusetts.

Over the course of the next three years, MRGI added 250 members and began a series of 10 riverwalks from the end of the river in Easthampton to the Williamsburg Dam Disaster site. MRGI spawned neighborhood committees in Williamsburg, Leeds, and Bay State and has self-guided riverwalk brochures for downtown Northampton and Leeds with a new one slated for Florence in 2015. In 2014, through its 501(c)(3) fiscal agent, the Connecticut River Watershed Council, MRGI raised funds from its members and entered an agreement with the Conway School to assemble the elements and create a structure for a strategic plan. For more information about The Mill River Greenway Initiative, visit: http://millrivergreenway.org

MRGI's mission is to reconnect communities living along the Mill River to the assets of the river including its historic significance and ecological importance.

Introduction

PROJECT GOALS & SCOPE Benefits of this document This document begins to compile the information that MRGI has gathered since 2009 when the members first conceived the Mill River Greenway. Organizing the existing research, maps, projects, and case studies, the Conway project team explores the complex process of identifying potential connections along the Mill River. Guided by MRGI’s goal to bring people back to the Mill River by highlighting historical and ecological resources, the project team focused the project’s scope to include data organization, assessment criteria, and recommendations for future tasks and projects.

The scaffolding resources and increase human access to benefit both by analyzing ecological factors such as wildlife habitat and protected land, and human connections such as land ownership and historic sites near the river. This document also offers a methodology for organizing existing MRGI data and identifies a criteria for future human and ecological greenway opportunities. Lastly, it suggests next steps that will ensure the continued implementation of the Mill River Greenway.

This project provides a framework that can be compared to a scaffolding for future implementation of the Mill River Greenway. Each component of the scaffolding moves the greenway forward. The bulk of this document focuses on context analysis incorporating community feedback, identifying ecological and human corridors, and generating context sensitive solutions based on existing site conditions. All of these will result in broad recommendations for the organization. The context will be elaborated on the following pages. A study methodology will then explain the process for identifying ecological and human corridors. Ecological and human corridors will be identified, and strategies for their intersections will be discussed. Lastly, broad recommendations will be made regarding next steps for MRGI to move forward with greenway planning.

Mill River Watershed Facts

The Mill River is located within the Connecticut River Watershed, and is part of the Pioneer Valley. The area is noted for its soils because it was once part of the glacial Lake Hitchcock that deposited ancient nutrient-rich sediment suitable for farming. Along with farming, the area has a long history of industry and water-powered industry along the many rivers that run through the area.

HISTORY OF THE MILL RIVER The Nonotuck Native Americans had a permanent settlement in Northampton until 1654 when two dozen families of English Colonists occupied the area, centering their village where the Northampton Court House is currently located. The colonists exiled most of the Nonotuck Peoples by the year 1670. For the first 150 years of colonial settlement in the Mill River watershed, most of the population remained in the area that is now downtown Northampton. By the 1660s, the

settlers built two dams on the Mill. The first was just south of the current South Street Bridge at Clark Avenue, and the second dam was at Paradise Pond (see map on page 14). After the American Revolution in the late 1700s, people began to settle upstream of Paradise Pond. By 1820, a string of factory villages had been established including Paper Mill Village in Bay State, and in Florence, Leeds, Haydenville, and Searsville. They thrived with the production from grist, saw, fulling, and textile mills.

By 1850, Florence had become the most important industrial site in the watershed with its silk and brush industries. Bay State became the site of cutlery and agriculture implement enterprises.

Context

1850 - Florence had become the most important industrial site in the watershed with its silk and brush industries.

The 1874 Flood was a devastating event that obliterated Skinnerville and destroyed all factories from Williamsburg Center to Leeds. This flood coincided with the decline of water power, as steam-powered factories began to dominate in the 1870s and were later replaced by new sources of electricity in the early 1900s. At that time, the Mill River was no longer used for power, and instead became a part of Northamptonâ&#x20AC;&#x2122;s tourist economy.

1890S

Several Northampton residents considered plans to beautify the river which had become a place to dump effluent. The river, however, flooded far too often and destructively, so in 1940 the United States Army Corps of Engineers diverted the river away from downtown Northampton. The map on page 15 shows the historic and current routes of the Mill River south of the Army Corps diversion.

The line in purple delineates the route the Mill River naturally took east through historic Northampton before the Army Corps of Engineers diverted its path west in 1940 (see bottom image, right). The main reason the Corps diverted its path was because the river flooded frequently and destructively through Northampton.

COMMUNITY MEETINGS Community meetings were held to identify areas that local residents consider both opportunities and concerns for the greenway on February 2 and February 29, 2016. At the first meeting, three map sections (south, central, and north) were posted around the room, and the participants were prompted to make notes on the maps or draw potential connections.

At the second meeting, the methodology for considering future ecological and human corridors was presented. Community members considered specifics including the logistics of greenway development. Because MRGI had already established many connections in the region, community leaders, ecologists, designers, and residents came together from all eight villages for the first time

to discuss a more cohesive vision. The image on the bottom right shows community members discussing â&#x20AC;&#x153;What excites them about the Mill River Greenwayâ&#x20AC;?, and the other four images were taken during the milling activity when participants wrote notes on each map.

STUDY METHODOLOGY

Study Methodology

IDENTIFYING CORRIDORS The question guiding this project is â&#x20AC;&#x153;How can a greenway enhance ecological resources and improve human access along the Mill River to benefit both?â&#x20AC;? If a greenway brings people and ecology together, criteria is needed to examine the ecological resources surrounding the Mill River and also determine the human circulation patterns that can provide favorable access to these and other resources along the Mill River Greenway. The following two pages present the methodology to determine criteria, analyze existing conditions and identify opportunities. The hiking area in Devil's Den located in the northwestern reach of the Mill River is an example where human and ecological corridors intersect.

Human corridors and ecological corridors can coexist, but first a methodology is needed to identify where these corridors should or should not be implemented.

Building a Strategic Plan for the Mill River Greenway

ECOLOGICAL CORRIDORS Ecological Corridors The ecological significance of the diverse critical habitat and wildlife corridors along the 15 miles of the Mill River greenway is considerable. BioMap2, jointly produced by the Natural Heritage and Endangered Species Program (NHESP) and the Nature Conservancy, is a strategic program to identify areas critical to biodiversity conservation in Massachusetts. BioMap2 provides a framework that identifies mostly unprotected habitats of rare animal and plant species and prioritizes natural communities. Together with a map that identifies existing protected lands, new opportunity areas become evident for the expansion and conservation of ecological corridors within the greenway. This process is further elaborated in the Ecological Corridors section.

BIOMAP2 PRIORITY LAND TO PROTECT

OPPORTUNITIES FOR ECOLOGICAL CORRIDORS To identify ecological corridors, priority habitat areas were mapped with existing protected land to identify corridor opportunities.

or a bike path. The Human Corridors section of this plan analyzes MRGI's identified opportunities in order to identify future opportunities. In order to perform this analysis, it was necessary to create criteria that help evaluate the quality of the existing corridors.

Where do people currently access the river and how? What are the issues of concern for landowners related to greenway planning and implementation? The answers to these questions identify opportunities for creating or enhancing access to the river.

Thorough review of MRGI data, including previous and current greenway projects, and discussion with community members led to the identification of four considerations that formed the criteria for analysis.

Human corridors include points of access, such as a parking lot with a trailhead. They also include connections between points of access to the river, such as a riverside trail

Looking at human proximity and topography reveals different ways of connecting people to the river.

ECOLOGICAL CORRIDORS

Glacial Lake Hitchcock in green (left) expanded across Vermont, New Hampshire, Massachusetts and Connecticut at its largest extents approximately 14,000 years ago. This glacial lake created the unique corridor of the Connecticut River and the Pioneer Valley. A variety of species call this corridor home including those depicted on the right.

Ecological Corridors

THE ECOLOGICAL CONNECTION What is an ecological corridor? The Mill River’s current landscape was shaped by the retreat of the glacially formed Lake Hitchcock (on page 22). Silts and clays from the bottom of Lake Hitchcock provide a thriving environment for a diversity of flora and fauna in this corridor. The Mill River watershed’s 1,330 feet of elevation change made the river conducive for hydro-power. While the mills provided a source of power for the settlers, they also were responsible for much damage and alteration to the river corridor leading to subsequent contamination.

The river’s health has rebounded since villages were no longer able to dump effluent into the water and water regulations have become stronger. Today, clear water babbles south exposing beautiful stones and supporting the life of many rare species including salamanders, turtles, and fish. (Sinton, 2016) Still, many threats to the river are visible. In denser areas, developed land abuts the river with little to no riparian buffer. Homes are continuing to be built between the river and the various roads that border it, further reducing vegetated buffers.

Runoff from pollutant-ridden roads, fertilized lawns, and dense housing developments flows into the Mill River untreated. Limiting development directly along the river and encouraging vegetated buffers for properties that already border the river will reduce the impact of contaminated runoff and help to stabilize the banks. Ecological corridors are created through connecting healthy space and critical habitat through enhancing the ecology along the river. This section will identify areas already protected and land included in the Natural Heritage and Endangered Species’ BioMap2 throughout the watershed in order to identify opportunities for connecting ecological corridors.

Construction projects directly along the Mill River are still in progress and should be limited for the health of the Mill River to ensure public access to the river's edge. Erosion and sediment control are critical to preserving the health of the river.

Some properties directly abut the Mill River. Stormwater runs off of roofs directly into the water. These properties were built before regulations restricted development within 200 feet of a river's edge. This pattern removes riparian habitat.

Building a Strategic Plan for the Mill River Greenway

EXISTING CONDITIONS Biomap2 Critical Habitat Protecting the quality of habitat along the Mill River can increase the ecological value of the greenway by strengthening and connecting existing corridors. The user experience would also be enhanced by connecting conservation parcels and providing potential public access routes. BioMap2 was designed by the Natural Heritage & Endangered Species Program (NHESP) and the Nature

Conservancy. Its mission is to guide strategic biodiversity conservation in Massachusetts over the next decade. BioMap2’s data consists of a combination of Core Habitat and Critical Natural Landscapes. Core Habitat refers to habitat that is “critical for the long-term persistence of rare species and other Species of Conservation Concern”, while Critical Natural Habitat consists of “large landscape blocks that provide habitat for wide-ranging native species” (BioMap2).

BioMap2 Core Habitat & Critical Natural Landscape

Notice on the map below that large patches of Critical Natural Landscape lie west and east of the river while core habitat lies directly along the river. The river is home to species of concern including the Eastern Box Turtle, the Ocellated Darner, Adder’s Tongue Fern, and the Jefferson Salamander. BioMap2 is designed to protect ecologically important lands from development by creating a guide for strategic land acquisition. An abundance of critical habitat is found within the Mill River watershed, indicating that this is a critical area to protect with appropriate ecological connections.

Existing Protected Land

CHAPTER 61 Chapter 61 is a law designed by the Massachusetts Legislature to tax property in Massachusetts at its timber, agricultural, or recreational value rather than its development value. Landowners who enroll their land in the program receive property tax reduction in exchange for a lien on their property. This also gives the town the right of first refusal, which is a temporary form of protection. The legislation was approved in 1973 and known as Chapter 61, the Forestland Act; Chapter 61A, the Farmland Assessment Act; and Chapter 61B, the Open Space Act.

CASE STUDY Darby creek Greenway Plan Administered by the Pennsylvania Department of Conservation and Natural Resources Bureau of Recreation and Conservation, and prepared by the Delaware County Planning Department in 2010, the Greenway Plan for the Darby Creek Watershed was developed as the first phase of greenway implementation. Centered around the Darby Creek watershed which contains 76 square miles and 26 municipalities within Delaware County, the greenway is a proposed continuous network of trails and connections from one end of the watershed to the other. The county’s definition of the proposed greenway is “a linear system of connected natural and man-made elements that function together for public benefit”. The five goals of the Darby Creek Greenway Plan are: 1. Conserving and preserving critical natural resources and unique environmental and historic character. 2. Providing a connected network of greenways that connect people to various destinations both in and out of the watershed 3. Improving and maintaining quality of life, well-being and economic health in the Darby creek watershed 4. Educating the public, policy makers and landowners about the benefits of greenways 5. Providing a framework with actions and policies for greenway implementation After detailing opportunities and challenges of 12 segments of the watershed study area in the plan, the following are examples of the recommendations made by the

There are many different types of greenways. While there are greenways that consist of dirt paths or trails, there are some trails that require a higher level of pavement and maintenance such as the concept drawn above. Depending on the vision, a greenway can contain just one kind of path or a combination of different types of paths.

Human Corridors

THE HUMAN CONNECTION What is a human corridor? The Mill River traverses a variety of physical, historical and ecological landscapes. Within these landscapes, a greenway can link bike paths, roadways, sidewalks, and trails in communities to strengthen peopleâ&#x20AC;&#x2122;s connections to village centers, recreational spaces, historic sites, and areas with ecological significance. From hikers and cross country skiers to history lovers and tourists stopping at a small town cafĂŠ, the Mill River Greenway can provide a diverse network of experiences to a wide range of users.

Reconnecting people to these resources strengthens peopleâ&#x20AC;&#x2122;s relationships to their surroundings but also expands their impact on the land. The human corridor is where the environment and humans come together. Understanding where and how people connect with the landscape provides an analytical framework for planning a greenway along the Mill River. Identifying new opportunities for connecting people to the river required the identification of criteria for human corridors. The criteria chosen included land use, historic significance, open space, topography, and human circulation. These factors contribute

to the variety of ways in which people interact with the river. Analyzing land use, open space and historic land encourages a greenway that respects privacy of private properties while providing public access to historical and recreational resources. Human proximity and existing topography establish opportunity areas where the Mill River could be easily accessible due to the physical features throughout the four towns.

There are many types of human corridors. Some are picnic spots while others are bikeways or trails, or scenic lookouts. For the Mill River Greenway, human corridors are places where humans can renew their connection to the Mill River.

Areas in the southern part of the watershed - Florence Fields corridor, Arts and Industry pocket park, Maines Field lookout, old mill raceways at Federal Street and the old Cutlery Building, and the Hidden Mill River all cluster near village centers where public access exists. These projects previously identified by MRGI consist of ongoing trail systems, research areas, yet to be established pocket parks or lookouts, and historic walking tours. The upper east branch and unused bikeway connector are ongoing trail projects. The Florence Fields corridor is a research area, while Arts & Industry pocket park and Maines Field lookout are yet to be formalized greenway points of access. The old mill raceways, the Hidden Mill River destination, and Brassworks building are historic walking tour opportunities.

Human Circulation

Criteria for analysis of human corridors From the eight opportunity areas that were identified by MRGI, some common characteristics became apparent. Property ownership plays a significant role because peopleâ&#x20AC;&#x2122;s private property is less favorable for greenway projects while publiclyowned land already accommodates public access. Historic sites reconnect people to the cultural resources of

the Mill River and inform them of the riverâ&#x20AC;&#x2122;s rich history. Open space provides opportunities for people to strengthen their relationship to ecological landscapes. Proximity to human circulation patterns determines how accessible the river already is to the community. Lastly, topography affects the types of opportunities available. Bike paths and gathering places such as parks are more likely to exist in flatter areas while hiking trails and lookouts are more likely to occur in steeper areas. Building a Strategic Plan for the Mill River Greenway

These common factors provide the framework for analyzing new human connections to the river. Land ownership, proximity to historic sites, and available open space are favorable for human circulation patterns. Locations of existing bike trails and paths and the existing topography determine the various types of opportunities that are appropriate in different landscapes.

LAND USE Land Use - Residential & Commercial Property

Goshen

Many residential and commercial properties back directly up to the Mill River, limiting public access to the river's edge. See appendix for map reference

Respecting the rights of landowners â&#x20AC;&#x201C; residential and commercial â&#x20AC;&#x201C; is an important aspect in determining where greenway facilities or features can be built. Community meetings held for this project served as a voice for landowners who did not want any trespassing to occur on their property. Historically, residential and commercial properties were established in close proximity to the Mill River due to its powerful energy resource for factories and mill industries. Today in Northampton, residential and 32

commercial land ownership is farther east of the river, where the historic river used to flow. (See map on page 15 for the historic channel location.)

Adding trail connections in these areas should be avoided and instead link to a network of existing trails, sidewalks, and other places of interest.

At the northern headwaters in Goshen, there are fewer residentially and commercially developed parcels adjacent to the Mill River which could provide opportunities to build more trails along the Mill River if topography is favorable. From Williamsburg to Northampton, privately-owned properties that border the river start to increase in density as it moves south.

Current use and private ownership at the parcel scale could not be determined at this scale and would be advantageous for continued greenway implementation.

Human Corridors

LAND USE SUMMARY GREEN / more favorable

RED / less favorable

Observations

Areas where residential and commercial land use is less concentrated along the Mill River are shown in green. These areas could result in fewer conflicts with property ownersâ&#x20AC;&#x2122; need for privacy while providing more public opportunities for connections to wilder or less developed areas along the river.

Areas where residential and commercial land use borders the river are shown in red. These sections present opportunities for best management strategies to reduce negative impacts on the river. This can include adding vegetative stream buffers, encouraging lawn alternatives, increasing use of native garden plants, and limiting compaction.

Less concentrated areas of residential and commercial land use along the river provide potential opportunities for new trails and human connections to the river. Concentrated areas of residential and commercial land use moving south can create challenges for creating human connections. Sections in red could lead to stewardship opportunities for people who live along the river to maintain its ecological health and opportunities for stewardship of existing trails. New trails or access would require careful siting and negotiations with landowners.

Note that areas farther north have little to no residential or commercial use along the river with some sections that do not include designated historic or open space. While all of these areas are favorable for a greenway, the areas with existing open space or historic significance should take priority over those with no designated historic sites or open space.

Farther south where the two branches come together, residential and commercial land use become more prevalent while open space or historic sites become fragmented. Connecting these areas, while not conflicting with residential and commercial land use, will need to be addressed on a sitespecific basis.

The raised bike path follows the river's edge near Leeds (top). In many cases, while existing roads make the Mill River very visible to drivers, roads also often act as a barrier preventing human access directly to the river's edge (bottom).

See appendix for map reference

Human circulation patterns help identify appropriate types of greenway opportunities based on the proximity of existing roads, parking areas, and trails to the river. From Goshen to Haydenville, there are fewer roads, which concentrate traffic along main roadways such as Route 9. New trails can be created from these existing roads with the implementation of parking areas with

trailheads that verge towards the river. Where Route 9 parallels the river, between Haydenville and Leeds, it offers high visibility and proximity for people along the road. Simultaneously, roads often act as a barrier preventing people from accessing the riverâ&#x20AC;&#x2122;s edge. Most of the roads are concentrated in the southern areas from Leeds to Northampton. There are two bike trails

Human Corridors

located in this area. The Manhan Rail Trail is a paved trail that is mostly flat with a total length of 6 miles within Easthampton. The trail continues into Northampton where it connects to a network of trails. From Northampton, bicyclists can follow the Mass Central Rail Trail which is a multi-use path that ends in Leeds. Moving north past Leeds, there are no other current bike paths.

HUMAN CIRCULATION SUMMARY YELLOW / Close to roads PURPLE / Farther from or trails roads or trails Areas shown in yellow are generally closer to existing roads and bike paths. These areas offer opportunities for new trails off existing roads where topography permits (see analysis on Page 40). Other opportunities, such as park and ride lots can be provided where bikeways exists.

The river is more secluded in areas that are in purple with fewer roads close to the river. These roads and paths do not border the river and have less human access. They are also less impacted by traffic. Places to park with trailheads towards the river can provide more access.

observations Sections of the river in close proximity to existing roads and trails provide more visible or physical access with potential opportunities for an expansion of trails. This will vary on a site to site basis, as in many cases the road acts as a barrier or there is little room for parking areas.

The steepness of slopes along the river vastly affects the character of the river, and types of greenway opportunities. The steeper slopes offer more dramatic views and could require erosion control in places. Steeper greenway sites

Flatter areas suggest different opportunities. They tend to be either floodplain or wetland habitat, or have already been developed. Flatter areas would also be easier to access with mixed use trails, gathering places, and interpretive signs.

The yellow areas denote relatively flatter land relative to its surroundings abutting the Mill River. Flat land may be more suitable for paved multi-use paths and walking trails.

Shown in purple are areas where steeper land is adjacent to the Mill River. Steeper sections may provide more hiking opportunities where trails can reach scenic views. These areas may be tougher to design based on slope stability and other factors.

Areas where the land is flatter provide more opportunities for humans to access the Mill River. Steeper areas, while more difficult to reach, can enhance different user experiences through challenging hiking trails, mountain biking trails, and park and ride scenic lookouts.

STRATEGIES

ECOLOGICAL AND HUMAN INTERSECTIONS How should ecological and human corridors intersect? In order to continue to create a greenway that both connects humans to the Mill River and enhances the ecological habitat, the intersections of ecological and human corridors must be carefully considered. Throughout the greenway, there are areas of critical ecological habitat. In many areas, human use has resulted in accumulated trash, compaction, unregulated mountain biking, river channelization, and erosion.

Moving forward, human impacts on the environment should be carefully considered, avoided, minimized or mitigated while best management practices should be considered. Designing low impact paths, planting vegetated riparian buffers, and incorporating green slope stabilization methods will be necessary to ensure the long-term stability of the landscape. The Department of Natural Resources (DNR) in Georgia has a thorough guide for slope stabilization. The diagram below depicts one method presented in their Streambank and Shoreline Stabilization guide. This method incorporates a vegetated

geogrid that uses both plantings and a natural geotextile material to strengthen riverbank slopes. (Georgia Environmental Protection Division, 2011) Along with minimizing human impacts, stewardship of the river is needed along its length. Stewardship groups should be established based on location. After assessing the health of the Mill River, these groups can form around areas that need ecological restoration including slope stabilization, invasive species mitigation, habitat enhancement, and corridor extension. These areas can also be used as research sites, and be adopted by friends groups.

Ecological Restoration Options Based on Existing conditions While identifying appropriate implementation options for human access is an integral part of the Mill River Greenway, context sensitive solutions for ecological conditions are also needed. The restoration options in the green boxes below can be applied to specific sites based on the existing conditions of the Mill River at that location. Further research will be required to identify areas where ecological solutions are necessary and human access should be limited. There are several resource assessment tools available that result in data that could guide future decisions. The

method used should be simple and easily replicable by volunteer groups. One method is the Stream Corridor Assessment Survey (SCA, see box on right). Below, the chart identifies four conditions that are found along the Mill River with solutions that respond to those conditions. More detailed solutions can be found on pages 50 and 51. In order to complete these solutions, a strong non-profit structure is necessary to coordinate volunteer efforts, write grants, and provide the framework needed for future efforts. Non-profit status for MRGI could result in a variety of benefits related to funding of projects and overall donations. See Recommendations section for more information.

STREAM CORRIDOR ASSESSMENT SURVEY The SCA Survey is a simple, easily replicable resource assessment tool developed by the state of Maryland. It was designed to assess the physical conditions of a stream system and identify the location of a variety of common environmenal problems within stream corridors. Data gathering consists of walking along the river and plotting through GPS-specific locations of environmental concern that can be mapped for future planning and assessment. The SCA methodology is recommended because it is a simple process where an entire system can be assessed over a long period of time by people with limited technical skills.

Mapping trail options supports the planning of the greenway by providing an overview of possible connections. Illustrating conceptual ideas in a detailed network map of proposed trails could provide a platform for grant applications and targeted fundraising. It can also designate potential and existing destinations that have not yet been accessed while assessing user demand on areas without trails.

Building a Strategic Plan for the Mill River Greenway

Given the scope of this project, the following are broad recommendations that can move the overall greenway project forward.

Categories such as community meetings, existing mapping, vegetation type, parcel data information, and historic points of interest are the few that are used to determine progress and next steps. Continuing to fulfill the data gaps and addressing the next steps for each village effectively will enable MRGI to engage in a comprehensive strategy.
