HomeMy WebLinkAboutCollege Street Trail Connection Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Thom White, Superintendant of Parks and Cemetery Ron Dingman, Director of Parks and Recreation Chuck Winn, Assistant City Manager SUBJECT: College Street Trail Connection MEETING DATE: August 24, 2009 AGENDA ITEM TYPE: Consent Item RECOMMENDATION: Approve the College Street Trail Connection as proposed in the August 13, 2009 Wetland and Clean Water Act Jurisdictional and Trail Location Assessment. BACKGROUND: On April 27, 2009 in a 5 – 0 vote the Bozeman City Commission directed staff “to work with the Gallatin Valley Land Trust [GVLT] to construct a trail connection from Black Avenue at College Street to connect east to the Gallagator Trail System in consultation with the homeowner’s association at College Street Condos” (Attachments 1 and 2). Additionally, Commissioner Becker suggested involving the Wetlands Review Board. Since late April, Staff, representatives of the College Street Condominium Association, GVLT, members of the Recreation and Parks Advisory Board, members of the Wetland Review Board and independent scientists and engineers have met on-site on numerous occasions to discuss the proposed trail route through the College Street Right of Way (Attachment 3). The Wetland Review Board submitted a “Field Meeting Summary” on June 4, 2009 which included several “Observations” and “Recommendations” (Attachment 4). One trail recommendation included performing formal wetland delineation if a 404 permit application [to fill the wetland] is sought. Ron Orton of Allied Engineering was contacted by College Street Condominium Association member Jerry Gossel to perform a wetland assessment. Todd Hoitsma also donated time and expertise to the delineation project at the request of GVLT (Attachment 5). The August 13, 2009 report concluded: [S]ince the trail will not result in the placement of fill in the wetland and that the ditch is likely not jurisdictional under the CWA [Clean Water Act], the trail should be established in such a manner that will limit destruction of vegetation and be in an agreeable location for surrounding residents. Permitting will not be necessary if wetland areas are avoided regardless of jurisdictional status. As outlined in the previously mentioned letter from the Wetland Review Board, vegetation along the corridor provides important functions not 90 only for wildlife, but privacy issues for landowners in the vicinity. The current trail configuration appears to address landowner concerns. Planting of barrier shrubs to promote security and reduce visual and noise impacts and/or solid fencing could be part of the consideration for the trail corridor. FISCAL EFFECTS: The proposed trail will be funded and constructed by GVLT with assistance and oversight from City Staff. Additional maintenance by the City Parks Division will be needed for this section of trail. ALTERNATIVES: As suggested by the City Commission.

BACKGROUND: Since the construction of the College Street Condominiums in 1991, the public has utilized the sidewalk along the north edge of the condos as an access to the Gallagator Trail system. A portion of this walk lies within the ROW but jogs onto private property about half way in as it travels east. Because of the close proximity to the adjacent homes, and occasional conflicts between pedestrians and homeowners, GVLT has proposed to develop a trail connector from Black Ave. to the Gallagator Trail. This would be constructed within the College Street ROW. By developing this trail connector, both the homeowners at the College Street Condominiums and the public would benefit from an increased buffer distance. FISCAL EFFECTS: The proposed trail would be funded and constructed by GVLT with assistance from City staff. Additional maintenance by the City Parks Division will be needed for this section. 6992 ALTERNATIVES: As suggested by the City Commission.

Box 1230 Bozeman, MT 59771-1230 Dear Commissioners and City Staff, Gallatin Valley Land Trust is seeking permission to construct a trail - described in detail below - within the College Street right-of-way, connecting South Black Street to the Gallagator Linear Park. GVLT would coordinate this project in partnership with the City Parks Department. GVLT believes it is important and logical to create a trail connection in this location to directly access College, which is one of the most important east-west streets in this area of our community, providing a connection to residential neighborhoods, commercial destinations, and the MSU campus. Project Description: As illustrated on the attached map, an approximately 300-foot long, six-foot wide natural fines trail would be constructed through a 60-foot wide parcel of City-owned property which is the easternmost section of the College Street right-of-way. The new trail would connect the intersection of South Black Street and College Street to the existing spur trail that connects the Gallagator Trail to Alderson Street. Located entirely within the public right-of-way, the trail would be part of the City’s “Main Street to the Mountains” trail system, providing a non- motorized public bicycle-pedestrian pathway. The College Street right-of-way parcel is heavily overgrown with trees and bushes. Along the parcel’s northern side, within the public right-of-way, there is a powerline corridor that consists of a raised berm with several powerline polls on it. At the base of the berm, along its south side, is a drainage ditch that was dug many years ago. GVLT proposes weaving the trail through the central portion of the right-of-way on the south side of the drainage ditch, cutting as little vegetation as possible and leaving as much of a vegetated buffer as possible between the trail and the apartments that border the south side of the public property. GVLT believes the trail should not be located on top of the berm or in the bottom of the drainage ditch for the following reasons: Ø A trail on top of the berm would be unsafe because a bicyclist who crashed over the side would face a potential fall, that could result in significant injury. Ø Trail users on top of the berm would be looking down into the backyard of the residence to the north, greatly reducing privacy for this property owner and potentially resulting in conflicts between the residents and trail users. Ø Placing the trail in the low area at the base of the berm would require cutting significant amounts of vegetation resulting in greater habitat destruction, and would present drainage challenges that would be difficult or impossible to resolve. 7194 • GVLT • P.

Willson, Suite E • Bozeman, MT 59771 • • 406-587-8404 • Fax 406-582-1136 • www.gvlt.org • landtrust@gvlt.org • Signage: At the west end of the new trail, where it intersects the Black Street sidewalk, GVLT would place a standard trail totem with a “Main Street to the Mountains” sign and directional signage. A smaller 4”x4” post with “Dogs on Leash” and “No Motorized” signs would also be installed at this trail entrance. On the east end of the new trail where it intersects the existing trail, a simple directional sign and post would be installed indicating the connection to College Avenue and Black Street. Trail Construction: Trail layout would be flagged by GVLT and approved by the City Parks Department prior to construction. GVLT would coordinate and supervise construction using City approved trail standards, and the work would be done using volunteers and donated materials. Every effort will be made to minimize the cutting of vegetation and the disturbance to wildlife habitat. This trail segment would be included in GVLT’s Adopt-A-Trail Program to assist with long-term maintenance. We anticipate construction taking place this summer. Background: This undeveloped section of the College Street right-of-way has a sidewalk running along its south side which was constructed as part of the College Street Apartments, which border the south side of the public property. For many years, trail users have used this sidewalk and a short section of user-created path to travel between the Gallagator Linear Park and South Black Street. Several of the apartment owners have objected to this use and over the last couple years have repeatedly tried to close this informal pedestrian connection. Reports of conflicts between some of the apartment owners and trail users came to GVLT’s attention in the fall of 2007. When the apartments were built in the early 1990s by Clair Daines, Inc., a reduced front yard setback was granted to the developer. The five-foot wide sidewalk was built along the north side of the apartments and outside this ten-foot wide setback. The very close proximity of the sidewalk to the front of the apartments is one of the reasons for the apartment owners’ objection to the public use. The section of the sidewalk starting at South Black and running in front of units 1-4 is located within the public right-of-way. The sidewalk then bends to the south into private property between units #4 and #5 and then terminates just beyond the last unit, #7. The user-created path continues across public property from the sidewalk’s dead end approximately 75 feet to intersect Gallagator trail spur at the north end of the bridge crossing Mathew Bird Creek. In an effort to try to resolve the conflicts between apartment owners and trail users, I met with the condo owners two times, in the spring of 2008 and fall of 2008. The apartment owner’s main complaint was about a lack of privacy due to the reduced front yard setback and close proximity of the sidewalk to their front porches. They also expressed concerns and fears about liability, dogs off leash, reduced property values, increased crime, vandalism, etc. I presented the owners with several possible solutions: Ø Allow the public to use the sidewalk but move the existing social trail at the end of the sidewalk further to the north to increase a buffer for the last apartment. 7295 • GVLT • P. O. Box 7021 • 25 N. Willson, Suite E • Bozeman, MT 59771 • • 406-587-8404 • Fax 406-582-1136 • www.gvlt.org • landtrust@gvlt.org • Ø Build a new trail from the bend in the sidewalk that would provide a buffer for the last three condos. Ø Build a new trail that is completely within the right-of-way and separate from the sidewalk. One of the apartment owners supported allowing public use of the sidewalk with an improved reroute at the end of the sidewalk or at the bend in the sidewalk. The other three owners opposed any public access to the sidewalk or any trail improvements within the right-of-way. The apartment owners’ association has since placed a sign on the sidewalk that indicates the sidewalk is only for the homeowner’s use and the use of their invited guests. In the latest development a formal police report was filed by one of the apartment owners against a neighbor who walked down the sidewalk to access the Gallagator Linear Park. Liability Concerns: GVLT has contacted City Staff to discuss the apartment owners’ liability concerns and it is our understanding based on these discussions that the apartment owners would not have any liability in relation to the proposed trail if it is within the public right-of-way. No Action Alternative: GVLT believes that taking no action is not a viable alternative as it would fail to resolve the inherent conflicts in the situation, and the two exiting trail spurs in the vicinity do not meet the need that would be addressed with the proposed trail: Ø The public has been using the sidewalk and the existing user-created path to access the community trail system for over 20 years, since the apartments were first developed. Unless a better alternative is provided the trail user/apartment owner conflicts will persist. Ø While there are two other trail connections in the area – at the south end of South Black and at the terminus of Alderson – both of these trail spurs connect to streets that lack a complete sidewalk system, forcing people to walk in the street. Also, neither of these spurs provides a good connection to an east-west street. In conclusion, we request the City’s approval and support for building a safe and useable connector trail through this public right-of-way. We believe our proposal represents the best solution for providing an adequate buffer to address the privacy issues raised by the apartment owners, while providing an important new connector trail that will enhance the walkability of the neighborhood, and be an asset to the community trail system.

Bozeman Avenue Bozeman, MT 59715 June 4, 2009 RE: College Street Right of Way Proposed Trail Dear Thom, On May 20, 2009, the City of Bozeman Wetland Review Board (WRB) met with you, Brit Fontenot (City Managers Office), and Bill Vandenbos (Park and Recreation Board) at the College Street right of way (ROW) to review placement of a proposed trail. The ROW is located between Black Avenue and Mathew Bird Creek. The length of the ROW is approximately 300 feet long by 60 feet wide. Within the center of the ROW is a ditch feature that was purportedly created before the 1960s and was used as an irrigation ditch. The ditch is 5 to 10 feet wide and the berm along the entire north side of the ditch was likely created during ditch construction; the berm is less than 6 feet wide. The east end of the ditch is also bermed. The ROW is bordered on the south by the College Street Condominiums and private residences on the north. We were informed that the west end of the current sidewalk along the north side of the condominiums is on City property. Observations made on May 14 and May 20, 2009: • Vegetation within the ROW is comprised of typical riparian species, including dogwood, chokecherry, cottonwood and burdock. • Three soil pits were excavated within the ROW: one at approximately the half-way point between Black Avenue and the creek within the ditch feature, another at the east end of the ditch near the creek and west of the end berm, and the third on the upper terrace adjacent to the central ditch soil pit. Soils were determined to be hydric within the ditch feature and were not hydric on the terrace. • Plant species within the east end of the ditch feature are considered wetland species; however the plant community through the remainder of the ditch was not assessed.. • Soil saturation was noted within 12 inches of the soil surface in the ditch soil pits; the terrace soil pit did not exhibit positive hydrologic indicators and may indicate that the terrace is not a wetland area. • The east half of the ditch feature would very likely qualify as a wetland. However, it is unknown how far the wetland extends toward Black Avenue, or how far the wetland may extend into the wooded terrace adjacent to the ditch. • The wetland is likely under federal jurisdiction because of its close proximity to the creek. • Two trail access points exist in close proximity to the proposed ROW trail: one on Alder Street and the other at the end of Black Avenue. 105 College Street Right of Way Proposed Trail June 4, 2009 2 • The wetland does provide valuable habitat for wildlife, namely avian species. During the site visits several bird species were noted using the ROW, including Pine Siskin, Evening Grosbeak, and Common Flicker. An ornithologist (Kevin Ellison) observed a White- breasted Nuthatch, an uncommon species according to the Montana Natural Heritage Program, in the ROW during the Christmas bird count. • The wetland performs a valuable stormwater retention service given the berm on the east end prevents untreated water from entering the stream. Trail recommendations: o A 404 permit application would be required to fill the wetland. The application must include a formal wetland delineation and survey to determine impact acreage. o It is likely the impact would be less than 0.1 acre and though the work would require a permit, no mitigation would be required by the Army Corps of Engineers. o According to the Army Corps of Engineers, wetland impact should be avoided, secondly, it should be minimized. Avoidance: ƒ There is an option not to build the trail at all, or if built, to not impact any wetlands. The Army Corps will want to know how this impact can be avoided; especially given there are two trail accesses in close proximity. The City should contemplate this issue very carefully; the proximity of the other trail access points is an argument against creating a new trail that will impact wetlands and stream. Minimization: ƒ If the trail is located within the ditch, a boardwalk could be used to minimize wetland impact. ƒ The trail could be placed on the upland terrace. ¾ Regardless how the trail is constructed, a very small wetland impact will likely occur when the ditch is crossed to access the trail to the east. o If the impact is minimized to one small (e.g. <200 square feet) location, a site-specific delineation (only in the location of the impact) could be done to minimize permitting costs. o We recommend minimizing impacts to the riparian vegetation if the trail is constructed. o We also recommend weed control of the ROW and garbage removal whether the trail is constructed or not. The Wetland Review Board would like to commend the Parks and Recreation Board, City Management Office and the Parks Department for seeking input from the WRB for this proposed trail. Please let us know if you would like further clarification or assistance on any of these, or other wetland or natural resource, issues.

Jerry supplied AESI with a letter from Lynn Bacon with the Wetland Review Board to Thom White the Parks and Cemetery Superintendant dated June 4, 2009. AESI agreed to donate time and resources to investigate the feasibility of the proposed trail system through the City corridor as an independent party. Todd Hoitsma also agreed to donate time to help with the wetland investigation. On July 23, 2009, Ron Orton and Todd Hoitsma collected relevant wetland data associated with the abandoned irrigation ditch within the City right of way. Gary Vodenahl and a GVLT volunteer were also on site to help out with plant identification, soil pit excavation and clearing of weeds within the right of way. Three data points were established within the abandoned irrigation ditch in order to determine wetland status of the area. Methods outlined in the Corps of Engineers Wetland Delineation Manual (1987 Manual) and recently published: Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region. The supplement was established as part of a series of regional supplements intended to provide accuracy of wetland delineations instead of relying wholly on the 1987 Manual. On-site data are gathered for routine determinations and involve simplified methods that result in sufficient qualitative data for making a determination. Data points are established in the field. Vegetation, soil, and hydrologic data are gathered and assessed at each data point. All three parameters must exhibit wetland characteristics before a positive wetland determination is made. If any one of the wetland parameters is not met, the area is classified as a non-wetland. The wetland boundaries and data points are shown on Figure 1. 107 August 13, 2009 Allied Engineering Services, Inc. College Street Right of Way Page 2 A positive wetland determination was made in the vicinity of Data Point 3 near the eastern portion of the ditch. The wetland was mapped generally following the topographic position of the abandoned ditch bottom and following the vegetation dominance of primarily red osier dogwood (Cornus stolonifera), a vegetation species that are generally found in and along wetlands and riparian corridors and appeared to be an indicator of wetland characteristics specific to this site. Hydrology associated with the ditch appears to be primarily groundwater. Water likely moves in a sandy layer approximately 8 inches to 16 inches below the ditch bottom for a portion of the year. Generally, flow is more frequent toward the eastern portion of the right of way near Mathew Bird Creek. This layer in the western portion exhibited redoximorphic features indicating periodic saturation, but this feature may be a relic condition from when the ditch was in operation. No indication of surface water in the abandoned ditch was noted and no indication of drainage to the ditch (except in the immediate vicinity of the ditch excavation) was apparent. There is a substantial berm that appears to have been historically filled that isolates the ditch from Mathew Bird Creek. Background information was used to perform a preliminary Section 404 of the Clean Water Act jurisdictional determination based on the US Army Corps of Engineers (USACE) Jurisdictional Determination (JD) Form Instructional Guidebook developed jointly by the US Environmental Protection Agency (EPA) and the USACE dated May 30, 2007. Our interpretation of the jurisdictional guidance is preliminary because the EPA and USACE make the final determination as to whether a given watercourse or wetland is jurisdictional under the Clean Water Act. The JD guidebook addresses ditches and on Page 36 states “Ditches (including roadside ditches) excavated wholly in and draining only uplands and that do not carry a relatively permanent flow of water generally are not jurisdictional under the CWA, because they are not tributaries or they do not have a significant nexus to TNWs. If a ditch has relatively permanent flow into waters of the U.S. or between two (or more) waters of the U.S., the ditch is jurisdictional under the CWA.” We conclude that since the trail will not result in the placement of fill in the wetland and that the ditch is likely not jurisdictional under the CWA, the trail should be established in such a manner that will limit destruction of vegetation and be in an agreeable location for surrounding residents. Permitting will not be necessary if wetland areas are avoided regardless of jurisdictional status. As outlined in the previously mentioned letter from the Wetland Review Board, vegetation along the corridor provides important functions not only for wildlife, but privacy issues for landowners in the vicinity. The current trail configuration appears to address landowner concerns. Planting of barrier shrubs to promote security and reduce visual and noise impacts and/or solid fencing could be part of the consideration for the trail corridor.
