9 Conner Creek Greenway Plan
Before cars and skyscrapers, Detroit was a natural prairie with wetlands, streams and creeks. Early settlers fi rst used canoes to travel along the Detroit River. Beginning in the 1700s, ferries transported people between Detroit and Windsor across the river. By 1882, ferries moved people to and from Belle Isle. (Baulch 2006)
The area around Conner Creek was inhabited by Algonquin and Iroquois indigenous people who fi shed and camped near its shore. Flowing from present-day Warren to the Detroit River, the creek provided a throughway for transporting furs and handmade items for trade with Europeans.
In 1700, the creek was named Trombley’s Creek after a powerful family that had settled nearby. This area experienced the same dramatic landscape change common to the region. Forests were cleared to make room for farming, granaries, and saw mills. Early
Conner Creek in the 1880s and 1890s:
“The picturesque Conner’s Creek Valley was perhaps one of the last…to be given up to the white settlers. The valley was afforded shelter from the harsh winter winds and an abundance of wild life inhabited the woods and drank from the creek. The stream teemed with fi sh that could be easily caught and edible nut trees grew on the banks… Each season brought new attractions to the creek and the valley. During the winter the valley was a winter wonderland that echoed with children’s laughter and squeals of delight as they coasted merrily down the snowy hillsides…After the spring fl oods had swirled through the high banks of the valley in a river of muddy water, the surrounding woods and hillsides took on a new life. Waxy yellow buttercups, pink hepatica, yellow adder’s tongue, blue violets, and purple wild geraniums bloomed in wild profusion. In the summer the vines of luscious black thimble berries laced the hill sides…and wild grapes, fed by the stream, grew large and juicy. The woods surrounding the creek were mostly of hard wood; maples, oak, hickory, elm, and black walnut. Here and there willows dipped graceful branches into the water. In the fall these trees turned the landscape into a Figure 3: Sanborn Maps Of The Greenway Area riot of color, while hickory nuts and black walnuts From 1930 To 1950 littered the ground….” (Watson 1907)

Conner Creek was a people to Southeastern Michigan and to the eastside good source of wholesome recreation. It was a of Detroit. In 1818, the creek was renamed Conner’s favored place for children to swim and catch frogs Creek in honor of the wealthy Henry Conner who despite being surrounded by smoky industrial had married a member of the Trombley family.

Farms dominated the creek’s edge during the 1800s, The city asked Edward H. Bennett to address this using it as a key source of water and transportation area as a part of his 1915 Plan for Detroit. Bennet had for their products. To make room for increasing assisted Daniel Burnham on the famous 1909 Plan farms, several portions of the creek were piped of Chicago and he went on to create City Beautiful underground.

By 1914, developing newspapers reported the city as failing to provide a greenway that ran six miles north from the river playgrounds for 78,000 of its 85,000 children. (Comey 1915).

Decades of natural degradation, social upheaval, and economic decline have left residents around the airport, and along the greenway, with few natural amenities. In addition, multiple schools and a police station have been removed from this area. The number of public institutions has decreased over time. Sanborn maps show a loss of housing in the southwestern portion of the corridor. Finally, despite the overall residential loss, single- family home lot sizes throughout this corridor have remained relatively consistent.
Conner Creek Greenway will return natural recreation to Detroit’s eastside along the path over the underground creek. Providing indigenous vegetation will provide children an outdoor classroom reminiscent of the children catching frogs in the 1920s. Winter sports like sledding and snow ball fi ghts might restore children’s enjoyment of the space, and landscaping will reintroduce the riot of color people experienced in the 1880s. We hope that greenway paths can produce wholesome recreation and mingling of neighbors the park commission strove for in the 1920s. Finally we hope that the greenway will be a restorative feature on the eastside that will help overcome the social struggles facing the area’s residents. The Conner Creek Greenway gives residents of Detroit’s eastside an opportunity to celebrate their natural and cultural past by enjoying their lives today.

16 CURRENT DEMOGRAPHICS
Income and race data from the U.S. Census Bureau in 2000 are important as they refl ect a large and disadvantaged population in our study area. Figure 6, illustrates the median household income where the northern areas (illustrated in darkest green) have higher median household incomes and lower incomes are clustered in the center (illustrated in light green). It is important to note, however, that areas with the highest median income do not earn more than approximately $53,000 per year. Though the entire study area is dominated by African American populations, the southern portion of the map, fi gure 7, has the highest concentration (as illustrated by the darker purple).

area has unique assets which will connect people to destinations including churches, schools, parks, and markets. See Appendix C for a complete list of assets near the greenway.
Community Asset Identifi cation Assets were documented within the study area. To assemble this community asset inventory, the project team conducted numerous site visits and windshield surveys and consulted local telephone books and web pages. Additionally, the team spoke with persons residing in the community and took photographs to identify probable user destinations. As a result of the team’s multi-pronged approach, an extensive asset inventory list was developed. To further ensure the accuracy of the list, the team contacted the asset locations by telephone to verify their existence. Mapping the community assets with Geographic Information Systems (GIS) in the project area allowed for an analysis of proximity of assets to the Greenway.
Proximity to destinations is key in determining whether a potential user will utilize the walkway:

Community feedback suggested selecting at least one church from each section (South, Central, and North) of the Greenway that was within a one half mile buffer. Schools Schools are valuable assets that will not only attract users but will also be key in programming. There are approximately 20 schools within one half mile of the Greenway, but there are many other educational institutions within the study area including Wayne County Community College. Approximately 34 educational institutions within the study area that offer after-school programs, such as tutorial, art and crafts. (See Appendix: D Schools Offering After- School Programs).
There are seven public educational institutions within one half mile of the Greenway that may be ideal for programming:

Libraries Libraries in the study area are valuable assets that can assist with programming and provide a destination for potential Greenway users. There are three public libraries in the study area including Chandler Park, Jefferson and Monteith Libraries.
Parks/Playfi elds Parks/Playfi elds are community assets that have the greatest potential for attracting users. These assets already exist and have physical and recreational facilities.
Shopping As in many Detroit neighborhoods, our communities have few markets or grocery stores and existing stores are not evenly distributed throughout the study area. For example, the Warren Conner Shopping Plaza is in the central section near the Greenway and it does not have a food market. However, Joe Randazzo’s fruit/vegetable market is located in the northern end of the study area. A number of party stores are located within walking distance to the Greenway, but the availability of affordable, good Figure 11: Educational Resources within Study Area

The involvement of the Detroit Department of Transportation (DDOT) can contribute Assets can also provide opportunities for to more walkable and healthy living environments.
Unfortunately, Detroit is ranked last in reliable public transportation among the nation’s largest cities (Colden 2000). This is primarily due to local government’s decisions to cut bus lines and eliminate jobs. The recent change to Detroit’s public transportation system presents a challenge to encouraging distant residents to use the greenway. Therefore, public transportation may severely limit opportunities for users. Figure 12: Key Nodes and Common Areas
20 The majority of Detroit’s Department of Transportation bus lines run along the major streets such as Conner Street, Gratiot Avenue, and Jefferson Avenue in our study area (see Figure 13). Using data from the City of Detroit’s Planning & Development Department, we created a graduated color GIS map to analyze ridership of the bus lines for the whole city. According to a representative from the home offi ce of DDOT, bus line ridership is categorized in three groups, high, medium and low. The representative from the offi ce has extensive knowledge of each of the bus lines and defi ned these categories based on working experience at DDOT. Therefore, these categories are not quantifi able. Lastly, bus lines selected for this analysis only included those which run through our study area. It is important to note that ridership alone does not measure quality public transportation services.
Our fi ndings indicate that the majority of bus lines have high ridership throughout our study area, but many are concentrated in the southwestern side (illustrated in dark blue see Figure 14 and Figure 15). Our proposed greenway has a long segment which Figure 14: Detroit Bus System Ridership runs down Conner Street. DDOT bus lines on the southern end may easily connect to Conner Street, however, the northeastern portion is less accessible. Transit-dependent users in this quadrant will not benefi t from the greenway if they cannot access it. In addition, the majority of youth between the ages of fi ve through 17 are located in the northeastern area and they are potential users we wish to attract (see Figure 8: Percentage of Children Age 5- 17). Transportation accessibility is a challenge for youth, in particular, those seeking green spaces and recreational activity. Most importantly, medical journals note that youth, seniors, and minorities are sub-groups who are more at risk of obesity (Goran 2001; Geffken 2001; Sallis 2000). Therefore an increase in bus service will be needed to provide youth living farther from the greenway with better access.
In contrast to this challenge in the northeast, adults 65 and over (primarily located on the south-west area) should not have a problem accessing the greenway via public transportation. Promoting and programming the greenway targeted for seniors on Figure 13: Detroit Bus Lines in Study Area the lower southwest-end will help improve health of
21 Conner Creek Greenway Plan this population.
It is also important to note that compared to the rest of the city bus lines, the Conner Bus Line number 13 has the greatest number of stops (Refer to Appendix E). The large number of bus stops offers users the most opportunities to access the greenway from Conner Street. Programming and design locations should consider the bus stops as they are major sites where transit riders enter and exit the greenway.

This can be further developed in In addition, we participated in the recent Citywide the next phases of the greenway. At this point public Greenway Charrette hosted by the Planning & transportation is a good means of connecting people Development Department.

Their second goal was to overcome current Community organizations might design routes and psychological and physical barriers to Greenway programming for greenways in their service areas, access. One of the most urgent psychological barriers while the organizing body would acquire funding is safety. For instance, they hoped the Conner Creek and handle maintenance for the entire greenway Greenway plan would address appropriate lighting system. This body would also take advantage of to enhance perceptions of safety. Also, dangerous economies of scale by handling maintenance and street crossings pose a physical barrier to access construction of the greenway. the greenway.

Suggestions for the greenway Some main concerns were that the Greenway area included surrounding users with attractive plantings is unsafe and unattractive. One individual noted how in the middle of the urban environment. dirty the neighborhood was and that she currently avoided the area due to personal safety concerns. There was a consensus that the area had a lack of quality destinations to attract people. One resident mentioned how she currently rides her bike to places such as Royal Oak because of the shopping and cultural attractions there. She would be inclined to use the Conner Creek Greenway more often if these destinations were available.
Food Food was the focus of one table of participants at the charrette. Several members hoped that community gardens could occur along the greenway, connecting physical activity and healthy eating together. Others believed that opportunities to purchase locally grown fresh food was lacking and needed in this area. An older gentleman hoped for an ice cream store that could become the focus of his bicycle trips with his grandson.
City Maintenance One table was primarily concerned with cleanliness, or lack thereof. The most frequently made point questioned the ability of Detroit to “green” a place before they bothered to clean the space. Specifi c areas of concern were mentioned as well as general anxiety over brownfi eld sites and illegal dumping sites. Residents wondered how the City’s administration could think that it would be benefi cial to provide green recreational space when they were not providing basic needs to a population whose fi rst concern was not leisure space. Additionally, this table felt that the City was selling prime riverfront property to private developers. Their perception was that Detroit is in such dire need of funds, the City is willing to give up a major asset because the land around the river was already cleaned-up, and developers did not want to clean brownfi eld sites within the interior of the City. The representatives in this discussion felt strongly that the riverfront should be a public space, similar to Chicago, and that Detroit has no right to sell that land.
In addition to a well-maintained greenway charrette participants desired an aesthetically pleasing

Figure 18: Crossing Diffi cult Intersections Along the Fred Pinellas Marquis Trail, Florida Another model city for traffi c calming in an urban environment is Vancouver, Canada. This city is using the familiar traffi c calming strategy of bulb-outs, or curb extensions. Bulb-outs serve the purpose of Figure 19: A Bulb-out in Vancouver, Canada slowing traffi c, creating a safer pedestrian crossing, and provide better visibility for both drivers and pedestrians. Another interesting greenway example is from the city of Tsukuba, Japan. This extensive greenway The Conner Creek Greenway will cross many streets, system links numerous destinations, such as parks, some of which are busy four lane roads. The use of offi ce complexes, and residential and commercial a pedestrian bridge might be used at the northern areas.

Further north, Calgary, Alberta’s Pathways provide The slogan for the Conner Creek Greenway, “Take Canadians with 635 km of pathways and 260 km of on-street bikeways. This massive system has earned the honor of being the most extensive urban pathway and bikeway network in North America. It is vitally important for the Conner Creek Greenway to link into such a system, and Detroit and Southeast Michigan are taking a step in the right direction through their greenway initiative.
Unique Qualities of Greenways The distinctive details of a greenway help create a sense of ownership among its users and make a public space unique and memorable. One example, the Hudson River Park, is very well designated by its distinctive signs and banners. The prominent display Figure 20: Greenway in Tsukuba, Japan of the park’s logo and name ensures that people are aware that they are in the Hudson River Park. The Me to the River,” presents a natural opportunity to Greenway also features distinct art deco style light promote water conservation. Although trees might fi xtures along its path and metal signage inlaid the not be left in the center of the greenway, the example surface. from Japan can serve as a reminder to preserve The Battle Creek Linear Park in western Michigan and respect as much of the surrounding natural environment as possible. The examples from Vancouver could certainly be adapted to Conner Creek to minimize stormwater run-off, especially the infi ltration bulges. Additionally, signs or pamphlets available along the greenway, particularly in Maheras- Gentry Park, could highlight the importance of protecting environmental assets and the importance of individual conservation behavior.
Connecting to a Larger Greenway System Connecting a single greenway into a larger greenway system multiples the benefi t of a single greenway to a region, creating more opportunities to use Figure 21: Art Deco Light Fixtures in Hudson River the greenway for commuting, providing additional Park, New York City recreational possibilities, and protecting future greenway corridor environments. One example of is a paved trail covering more than 17 miles. One this is Hudson River Park.

The fi rst attractive feature pedestrian and bicycle route connecting parks and is the detailing of the urban trails. As Robert Searns open space throughout the historic Hudson River describes, “Surfaces ranged from inlaid stone to

In many places, fi nely cut stone curbing was carefully laid to defi ne the trail edges. In places I saw all kinds of natural security fencing created using vines attached to a post and wire framework—a far better look than chain link” (Searns 2001).
Tsukuba also has a unique system of rentals. If one wishes to rent a bike for use on the greenways, they are available at a number of automated city- run stands. The renter drops a 100 Yen coin ($1) in to free the bike, and when the bike is returned, the renter receives their coin back. If the renter leaves the bike at the side of the path, rather than taking the time to return it, a capitalizing child will bring the bike back to a stand to get the coin. As Searns points out, the success of the system is likely at least partly due to the ethical values of the Japanese culture (Searns 2001).

Conner’s current unnecessary width encourages motorists to drive faster than is often considered safe for pedestrians or than is allowed by speed limits. Traffi c calming techniques can be used to increase safety and comfort for Greenway users at these intersections. Pedestrians’ ability to cross streets safely increases disproportionally as the speed of cars decreases (Watson et al. 2003).
Narrowing Conner is the most obvious and needed traffi c calming measure for the Greenway. The traffi c counts for Conner clearly Figure 30: Clearly Marked Crosswalks Can Ease East-West Crossings Where No indicate that the fi ve lanes Traffi c Lights Exist of traffi c are not necessary.
35 Conner Creek Greenway Plan Narrowing the street to make additional room for plantings and the path of the Greenway will also help to slow traffi c along Conner.

After a short period fi xtures settle into their maintained footcandle intensity and this lower level of light extends over the life of the system (Larsen et al. 2000).
To fulfi ll the coverage, minimize light pollution, and promote sustainability goals, we are recommending using a short solar bollard along the greenway. The intensity of light at the source is 18 foot candles which can easily create good coverage and eliminate dark spots when positioned properly. Because they are not connected the power grid, they are environmentally friendly and save up-front underground wiring costs. They are designed for heavy use in public spaces and thus have a reinforced shell with multiple fi nishes to prevent deterioration. The long-lasting lamp and multi-layer exterior allow for approximately fi ve years without maintenance. For outdoor use, no care is required. For scratches and gouges, sanding and repainting with a touch up kit can restore the appearance of a bollard fi xture.
These lamps have solar energy collectors positioned unobtrusively on the fi xture.

SURFACING The surfacing recommendations for the Conner Creek Greenway are based on non-motorized transportation, such as walking, running and biking. The currently constructed portion of the Connor Creek Greenway is black asphalt, and is the material used for surfacing most roads.
Surfacing issues to consider include maintenance, drainage, and the ability to add decoration or directional marking to the surface. As with all physical elements, maintenance of the trail surface will be required. Appropriate drainage structures must be in place to deal with heavy rain events. Access Figure 40: Example of Festival Sign, Washington, DC must comply with the Americans with Disabilities Act (ADA).
44 ADA states that: “An accessible trail is a trail that is accessible to and usable by people with disabilities and meets the minimum guidelines established by the U. S. Access Board. Access routes are stable, fi rm and slip resistant…examples of accessible trail criteria include: surface, maximum running and cross slopes, tread width, passing space, resting intervals, and edge protection” (Americans with Disabilities Act, Accessibility Guidelines 1990). Slopes may not be greater than eight percent and there must be curb- cuts within greenway connectors to allow access for disabled users. “An accessible surface for pathways is defi ned as fi rm, stable slip resistant surface, e.g. concrete, asphalt, compacted crushed limestone...” (Larsen et al. 2000, 3).
Surfacing Options Surfacing options are often determined based on proposed and existing uses. All surfacing can be categorized as either hard or soft. The portion of the Greenway currently constructed is black asphalt, one of the hard surfacing options. There are additional hard surfaces such as porous pavement and poured Figure 41: Curb Cuts Increase Accessibility And Comply in place concrete.

Additional Considerations for Surfacing Research further verifi es that the surfacing options have strengths and weaknesses in terms of maintenance and cost considerations. The following exerpt is taken from American Trails’ Trailbuilding Resources: “These confl icts often lead designers into exploring possible trail surfacing options (of which there is more every year), including: traditional asphalt and concrete permeable asphalt and concrete commercial soil stabilizers, geotextile confi nement systems… In arriving at a recommended trail surface, several key criteria should be considered including:
