STATEMENT OF WORK
PERCHE CREEK TRAIL ALIGNMENT PROJECT
City of Columbia
Sally Smith, Bill Jones, Sammy Wammy, Truman Tiger
February 11, 2007
The groupÕs goal is to develop a preliminary location for the Perche Creek Trail along the western border of Columbia between Interstate 70 and its intersection with the MKT trail. The trail will be part of the Columbia PedNet trail system that connects different sections of the city and neighborhoods in the community. We will develop a trail location that provides an enjoyable experience for users that also addresses the concerns of our client, which include construction cost limitations, ADA accessibility issues, land ownership rights, among others.
1. Before performing actual field work, the group must establish a rough outline of the trail location based on a number of forms of data including:
a. Topographical maps and digital elevation maps of the area
The topographical maps will be used to identify low-slope areas for the trail which the client has identified as highly desirable; these include areas that do not contain any large slopes such bluffs, hills, ravines, or other natural features. These maps will also help identify any smaller tributaries of Perche Creek which may need to be avoided.
b. Flood data maps
Flood-plain and flood-way maps will be used to identify locations where the trail cannot be located based on established guidelines provided by the City.
c. Parcel maps
Parcel maps will be used to identify land ownership.
d. Easement data
Easement data, obtained through county deeds and maps will be used to identify parcels that the City of Columbia already has some access to for construction.
e. Aerial imagery
Aerial imagery will be combined with the data mentioned above to identify a preliminary location for the trail based on factors such as tree cover, land type, and proximity to certain physical features.
This data will allow us to identify landowners that may be affected by the trail and whose property we might cross while performing field data acquisition. Contact will be made with affected landowners before fieldwork is performed.
2. After determining a preliminary trail route, field work will be performed to establish a much more exact trail location. Field work will allow us to identify issues that may not have been visible or noticeable in our preliminary data gathering. This determination will be based off of several on-site factors as we walk the trail location.
Team members will walk the trail looking at drainage patterns (including ravines, small tributaries and ditches,) specific land cover, scenic value, trail grade, potential neighborhood connections and connections with other trails, specific bridge locations, and other concerns as provided by the client.
3. The next step is to assemble and combine data gathered and compiled during our initial research with data gathered during our on-site examination of the trail location. We will then produce a draft of the final map(s). The draft will be used to walk the trail once again with GPS gathering tools so we can more precisely map the trail location. It is during this step that we will confer with staff members from the City of Columbia as the client deems necessary to make sure the trail meets technical expectations. If there are problems with our findings, they will be addressed, the trail will be remapped, and we will continue with that process until it meets their specifications. Maps will be created using Arc programs.
4. The final step is producing the final map(s) and creating any associated reports and presenting them to the client.
1. Final map with location of the trail and any necessary bridges or other construction needs. Also marked will be locations of potential neighborhood connections and other trail connections, land ownership, existing and planned developments, potential bridges and span lengths, trail alignments along the creek and trail lengths, total elevation change and maximum grade, parking areas, and rest areas.
2. Any supplementary maps deemed necessary by the client.
3. A report with information on our decision-making when the trail location was decided upon.
Schedule of Methodology
A rough outline of the trail location based on data gathered from topographical, flood data, and parcel maps as well as parcel data and aerial imagery will be finished by February 28. Landowners affected by our study will also be notified by that date.
Field work based on the preliminary map will be performed throughout March. Data will be gathered and compiled throughout the first two weeks of April with a first draft completed and presented to the client by April 10.
The final map(s) will be produced in the last two weeks of April.
A presentation of the final map and associated report will be made during the first week of May.
Weekly or bi-weekly contact will be made with the client as either group deems necessary. E-mail and phone contact information has been shared and all team members are reasonably accessible.
ROLES AND RESPONSIBILITIES
The client is asked to provide information and provide guidance on legal matters relating to land ownership issues, budget issues, and engineering concerns related to trail construction. They are asked to identify problems they may see in our assessment of trail location and make us aware as early as possible of changes that might be needed.
The following roles will likely change as we get deeper into the project, but based on initial assessments, this is our current thinking.
Truman Tiger will serve as liaison between team and client and any other organizations that may be involved in the project. He will participate in field work and contribute in decision-making for trail location.
Sammy Wammy will serve as writer for many of the documents needed during the project. He will also participate in field work and contribute in decision-making for the trail location especially in areas concerning terrain.
Bill Jones will serve as data manager for the project and assist with map creation. He will participate in field work while contributing to the decision-making process for trail location.
Sally Smith will serve main consultant for map creation. She will also participate in field work while contributing to the decision-making process for trail location.
Truman will handle most correspondence between the team and the client including their representative. During face-to-face meetings, all team members will contribute to discussions with the client.
None at this time.
