KCROS East Plum Thicket-Manzanita Social Trail Conversion Plan Prepared by Jeff Lyslo and Dan Mullins, Volunteer Trail Coordinators March 2017
Overview There are a number of existing social trails between Mountain Laurel, Manzanita and Woodruff Streets. In the Trails Master Plan (TMP), these are identified for upgrading and incorporation into the recognized and sanctioned trail system. This report and study has been assembled to facilitate accomplishing that TMP goal. Summary of There is approximately 3,800 linear feet and 7 different segments of existing social trail in the project area. Some of this trail is in reasonably good shape and only needs to be de-bermed and widened slightly. Elsewhere, trails are sitting on property boundaries and need to be relocated away from boundaries. There are other sections that run along fall line and are eroded and need to be re-located to bring it up to community trail standards.there are multiple connections and possible connections to other existing trails that are addressed as part of this study to create maximum efficiency in the whole trail system. The total length of the trails when implemented as recommended would be approximately 4,325 ft. When completed, the trails should meet the all standards the community has set out for new trail construction. This document represents an analysis of what the current issues / deficiencies are in meeting these standards, along with recommendations for how to remediate these issues and an action plan for implementation. This plan was developed by Jeff Lyslo and Dan Mullins, volunteer trail coordinators, in March of 2017. The guiding principles in developing recommendations : Create trails that will conform with community set standards for new trails. Construction of 24 inch wide, hand built, natural trail surfaces. Create trails that will be durable / minimize erosion. Preserve cultural artifacts in the study area. Maximize distance from private property boundaries where practical. Create maximum connectivity with surrounding existing trails Increase trail user safety Better protection of Open Space Resources The existing trails have been broken down into 12 segments that have similar characteristics. For each segment, there is a page describing the current trail conditions, associated photos, recommendations to address problems and an estimate of the time and materials required to implement the recommendations. Summary of Some of the recommended solutions contained herein include: re-routes, de-berming and widening of trails, creation of drainage dips, boardwalks through wet sections and 1 bridge to cross a semi-permanent water feature. General to all segments, Staff will do a walk-through assessment of plants in the project area to be sure there are no biology issues that need to be addressed. Full implementation of the recommendations contained in report will create a sustainable set of trails for many years in the future and create multiple stacked loops with other portions of the existing trail system. Following this overview, there is an index map of the trail segments. At the end of this document, there is a summary spreadsheet of key project metrics, listed by segment.

Segment 1 From west end connection to crusher fine trail to connection with segment 2. This is an efficient alignment for east-west travel on the trail. Approximate Length : 335 feet 1. The segment has good cross slope (photo 1) and good sinuosity (photo 2), creating short, well drained sections. 2. The tread is narrow and slightly cupped in places. 3. The current alignment has good separation from all property boundaries Maintain the existing segment : 1. Keep the current alignment 2. Widen the tread to 24 inches 3. De-berm where tread is cupped 4. Disperse spoils from items 1 and 2. 5. Add 2-4 drainage dips, evenly spread out, along longer straight sections. Details Map and Descriptions : Drainage Segment 1 Crusher fine trail (red) Photos : Photo 1 : Good cross-slope and separation from property lines, looking east. Estimated Time and Resources to Implement 12 man-hours, Trail Club volunteer time No additional resources Photo 2 : Good sinuosity of existing alignment creating short tread sections Photo 3 : West intersection with crusher fine trail, looking east Photo 4 : East intersection with segment 2, looking southwest
Segment 2 Details Map and Descriptions : A fall line short cut from the crusher fine trail to the main trail (at the intersection of segments 1 and 3). This segment is present because users traveling north on the crusher fine trail and turning east on the main drainage trail find this route more efficient than continuing to the west end of segment 1. Approximate Length : 100 feet Drainage 1. The segment is fall line over it s entire length, which will lead to erosion with time. 2. Most of the tread grade is in excess of 10% (greater than standards) 3. There is minor erosion but this would increase with greater use when adopted into the system Although this segment has significant technical deficiencies, use patterns indicate it will continue to be used because it is a highly efficient route. It will difficult to close because of this efficiency and there are not any viable and efficient route options, given the proximity to property boundaries to the south and presence of segment 1 to the north. 1. Keep the current alignment 2. Harden the southwest / steepest portion to prevent erosion. This is preferred to wooden water bars because cycling traffic will go across stones but tend to go around water bars. We believe water bars will lead to 2 trail braids and erosion, where as a hardening solution with rocks or masonry pavers will not. 3. Add 1 drainage dip mid way on the hardened section and one dip at the bottom of the hardened section. This will prevent water flow and erosion below the hardened section. 4. In lower section, create short tread segments (~ 25 ft) by building earthen drainage dips. 5. Widen tread to 24 inches as needed Estimated Time and Resources to Implement Photos : Crusher fine trail (red) Segment 2 30 man-hours, trail club volunteers Staff assistance to procure and deliver hardening materials Photo 1 : Steep fall line alignment, looking southwest. Photo 2 : Steep fall line alignment, looking from crusher fine trail northeast. ~ 120-140 sq. ft of rock or masonry pavers for hardening (2 ft wide x 60-70 ft long)
Segment 3 Details Map and Descriptions : From the intersection of segments 1 and 2, east to the pinch point between the property lines to the south and the stream course to the north. This segment is largely acceptable in its current form. Approximate Length : 215 feet 1. The segment has reasonable cross-slope along most of its length (photo 1) 2. Current grade is less than 10% (within standards, photo 1) 3. There is minor erosion and cupping (photo 1) Segment 3 Drainage The only potential issue with this current alignment is that on the east end, the trail gets fairly close to properties to the south. However, with the stream course to the north, there is very limited room to move the trail north and gain space from the property boundaries. This would also require adding a fall line segment to the west to rejoin segments 1 and 2, which is not desirable. Photos : Crusher fine trail (red) Property Boundaries (dashed magenta) Additionally, the houses sit up considerably higher than the trail and have some large trees between the houses and the trail. This combination leads to minimal viewscape impact of the trail on the houses to the south. Considering these observations, we believe the existing alignment works well. 1. Keep the current alignment 2. Widen the tread to 24 inches 3. De-berm where tread is cupped 4. Add 2-4 drainage dips, evenly spread out, along longer straight sections. Estimated Time and Resources to Implement 8 man-hours, Trail Club volunteer time No additional resources Photo 1 : Slightly cupped and narrow tread Cross-slope from left to right. Looking west.
Segment 4 Details Map and Descriptions : From the pinch point between the drainage and property boundaries on the west (east end segment 3) and the Mountain Laurel-Purple Ash connector crusher fine trail on the east. The trail is composed of 2 straight fall line segments. Approximate Length : 360 feet Mountain Laurel- Purple Ash connector 1. The segment is composed of 2 straight fall line sections (photo 1) 2. The tread is narrow and slightly cupped in places. 3. The current alignment has good separation from all property boundaries proposed re-route The current alignment does not meet current trail standards because it is running along fall line. With increased use after adoption into the trail system, this will eroded easily and be difficult to maintain. To address this, a new alignment is proposed to the north, with greater cross slope and greater sinuosity which will lead to a better drained and more durable tread surface. This alignment has the additional benefit of maximizing distance from houses on both the the south and north side of the Open Space. Photos : Fall line segment in photo 1 1. Re-route segment to the north per the map (photo 2). 2. Build re-route to new trail standards ; 24 inch tread, 3-5 deg outslope, etc. 3.

Segment 5 Details Map and Descriptions : Photos : From Mountain Laurel - Purple Ash crusher fine trail on the west to Stone Bridge on the east. Drainage (green line) Property Boundaries (dashed magenta) User Hazard falling into drainage Approximate Length : 605 feet Mountain Laurel- Purple Ash connector crossing proposed re-route Willow section for boardwalk Stone bridge crossing 1. The segment mostly runs right along the south property boundaries (photos 1, 4 and 6) 2. It is pinched in 2 places between the property boundaries and drainage with unsafe user conditions, where users could fall into the drainage (photo1) 3. There is a marshy / willow covered section that runs all the way across the open space, from south property line to north property line (photo 5) 4. The restored stone bridge is at the east end (photo 2) 5) There is an old concrete foundation on the east end of the willow area (photo 3) This is the most difficult section to bring into the system with multiple challenges. The tread needs to be moved off the property lines. Because the drainage pinches the south property lines, this means the alignment needs to be moved north of the drainage axis. To facilitate this, there are two existing drainage crossings which will be used: the Mountain Laurel-Purple Ash crossing (see photo 3 in segment 4) and the old stone bridge (photo 2). drainage pinch point drainage pinch point (photo 1) Old concrete foundation (photo 3) Property Boundaries (dashed magenta) Photo 1 : Current trail pinched between drainage and fence, looking west The middle section of the proposed alignment runs through an area on dense vegetation that is seasonally wet. Because the vegetation runs across the entire width, we believe the best solution is to find a relatively high point in the middle. By being in the middle, maximum property boundary seperation is preserved. Because this is seasonly wet, a raised boardwalk will be needed through this section (approximately 125 ft in length, minimum). This is a recommended solution in the water quality section of the Comprehensive OS Management Plan update. This section should be monitored in the spring to determine if there are additional wet sections that will need more boardwalk. Staff and VCLs will continue to discuss and determine the exact amount of boardwalk needed. Photo 2 : Stone Bridge crossing, east end Finally, the alignment for the re-route has been placed to not disturb the old concrete foundation but is close enough that if the Historical Society wanted to put up informational signage, like they have at the stone bridge, it could be easily incorporated. They should be consulted prior to final design approval for concurrence. 1. Re-route entire segment to the north per the map. 2. Perform a wetlands survey on segment prior to implementation of alignment and plan. 3. Contact Historical Society to provide guidance on importance and protection of identified structures. 4. Build re-route to new trail standards; 24 inch tread, 3-5 deg outslope, etc. 5. Use turf from re-route to reclaim current tread 6. Place temporary buck and rail on either end to discourage continued use of existing alignment until vegetation is established. 7.On west end, bring trail across drainage at existing crossing for Mountain Laurel - Purple Ash trail to tie to re-route of segment 4. 8. On the east end, bring trail across drainage at restored stone bridge. 9. Build a boardwalk through the willow section (~125 feet minimum) Photo 5 : Middle willow section, looking west Photo 6 : Current trail along fence line, looking west Estimated Time and Resources to Implement 55 man-hours for building non-boardwalk sections, Trail Club volunteer time Ranger Staff to deliver and install buck and rail, deliver supplies for boardwalk 80 man-hours to build boardwalk, Trail Club volunteer time Photo 3 : Old concrete foundation Photo 4 : Current alignment (red dashed) along fence and proposed re-route (green dashed), west end looking west
Segment 6 Details Map and Descriptions : From the Stone Bridge on the west to the intersection of the Manzanita segments on the east. Approximate Length : 125 feet Stone bridge Segment 6 Manzanita trails 1. The segment is already mowed for community access to the stone bridge 2. The tread is narrow and slightly cupped. 3. The current alignment does not have issues with proximity to property boundaries. 4. The current alignment does not have issues meeting established trail standards Drainage axis Bridge crossing 1. Keep the current alignment 2. Widen the tread to 24 inches 3. De-berm where tread is cupped 4. Disperse spoils from items 1 and 2 5. Add 1 drainage dip mid-way along segment. 6.

Segment 7 Currently runs from the Stone Bridge - Manzanita intersection and runs to Woodruff St., providing access to the elementary school. An extension is proposed to connect to the concrete trail along the drainage east of Valley Parkway. Approximate Length : 185 feet (school connector ) + 545 feet (Valley Pkwy connection) Details Map and Descriptions : Photos : Stone bridge Manzanita trails Marshy thicket Drainage axis Existing concrete trail (red) Valley Pkwy connection Bridge location Option 1 1. The existing segment is already mowed for community access to the stone bridge 2. The current alignment connects the trail to the elementary school (photo 5). 3. The tread is narrow and slightly cupped (photo 4). 4. The current alignment does not have issues with proximity to property boundaries. 5. The current alignment does not have issues meeting established trail standards 6. The proposed Valley Parkway connection will run through open grassland (photo 3) and will cross a drainage on it s east end (photo1). Segment 7 East Extension, option 1 (red) East Extension, option 2 (green) East Extension, option 3 (magenta) Bridge location Option 1 Bridge location Option 2 Right angle crossing to slow bike traffic Drainage axis Photo 1 : Option 1 bridge location, drainage crossing Looking SW from Valley Pkwy. The extension to Valley Parkway and the existing concrete trail (photo 2) was included in the TMP to create another closed loop within the Ken Caryl trail system. 3 options could be used to connect : 1) Option 1 is closest to the woods on the north edge Pluses: Most efficient route. Narrowest drainage crossing. User-Desired edge effect. Minuses : Bike traffic could flush deer onto Valley Parkway 2) Option 2 runs through the middle of the meadow and has several sharp turns to slow bike traffic prior to drainage and Valley Parkway Pluses : Mitigates wildlife flushing concerns. Still makes direct connection to concrete trail. Minuses : Less efficient than option 1 3) Option 3 follows the existing sidewalk. Pluses : No new disturbance. No wildlife flushing Minuses: No sense of continuation of the trail system along the drainage, creating a discontinuity in an otherwise continuous trail from the top of Lost Canyon through the bottom of the Mastodon trail. The VTCs favor option 1, followed by option 2. Photo 2 : Connection to concrete trail at Valley Pkwy, looking east. Photo 3 : Grassland area of east extension, marshy thicket in background, looking west. Photo 4 : Existing trail, looking NW. Slightly cupped and narrow. Photo 5 : Existing trail, looking SE. Access to elementary school, seen in the background. 1. Keep the current alignment 2. Perform a wetlands survey on segment prior to implementation of alignment and plan. 3. Widen the tread to 24 inches 4. De-berm where tread is cupped 5. Disperse spoils from items 1 and 2. 6. Add 1-2 drainage dips, evenly spread out, along longer straight section. 7. Add eastern extension to Valley parkway, per the map, built to community new trail standards. Final option to be determined by OSC and staff after community input 8. Staff to determine if there are any ROW issues with the bridge on east end and procure any needed permits. VTCs will provide Staff with any supporting documents needed in obtaining permits. 9. Add a bridge, similar in design to trail bridges currently installed on Lost Canyon and High Meadow trails, at the east end of the alignement (photo 1 location). Length 15-20 ft. 10. Add signage on either side of Valley Parkway cautioning trail users about crossing traffic Estimated Time and Resources to Implement 10 man-hours for upgrading existing tread, Trail Club volunteer time 55 man-hours to build eastern extension to Valley Parkway, Trail Club volunteer time 20 man-hours to build and install bridge on eastern end of alignment Open Space Staff to buy materials for bridge.
Segment 8 This segment runs from the intersection of the main west branch to the intersection of the Mountain Laurel access, parallel to Manzanita. Details Map and Descriptions : Photos : Approximate Length : 395 feet 1. The segment runs along several property boundaries backing to Mountain Laurel (photos 1 and 2) 2. Existing tread is narrow but general well drained and has reasonable cross slope 3. There is a drainage and diversion to the east of the existing tread (photos 3 and 4). The existing trail in pretty good shape and could be upgraded to meet new trail standards, however it is too close to several property boundaries (photos 1 and 2). As such, it needs to be moved east. There is a drainage diversion structure that sits about mid way between Mountain Laurel and Manzanita which is ideal for the new alignment. If placed on the west side of this feature, it provides a good cross-slope for drainage and provides viewscape protection for property owners on both sides of the Open Space. This alignment does require a drainage crossing which may be seasonally wet. This crossing may require a board walk for the wet season. This decision can be made after observing the conditions and deciding if it is necessary.

Create new tread, per the map alignment, 24 inches wide, according to community new trail standards. 4. If needed, on cross slope section of drainage diversion, build up tread with new material instead of cutting into drainage feature. Staff to investigate if this building up is needed or not. 5. Use turf from re-route to reclaim current tread 6. Place temporary buck and rail on either end to discourage continued use of existing alignment until revegetated. 7.

Segment 9 Details Map and Descriptions : Photos : Segment 9 Short connector trail from Mountain Laurel to main Mountain Laurel-Manzanita Open Space. Approximate Length : 195 feet 1. The segment in pinned in by property boundaries on both sides (photo 1) 2. The tread is narrow and slightly cupped in places (photo 1) 3. There is a small tree on the west end that the trail goes under, with branches impeding users (photo 2). short tree re-route Property Boundaries (magenta dashed) There is little that can be modified on the current alignment, due to property boundaries on either side. In photo 2, two braids are seen, associated with users trying to avoid tree branches. The solution is to have a short re-route to the south side of the tree, where the branches are taller. Photo 1 : Narrow, slightly cupped trail. Looking west. 1. Keep the current alignment, except at the tree and have a short re-route around the tree on the south side. 2. Widen the tread to 24 inches 3. De-berm where tread is cupped 4. Disperse spoils to the east in the main Open Space corridor, or possibly for reclamation on south end segment 10 (see segment 10 discussion). Estimated Time and Resources to Implement 8 man-hours, Trail Club volunteer time No additional resources Photo 2 : Lone tree impeding users, causing braid to form Re-route dashed in green; Looking west.
Segment 10 Details Map and Descriptions : This segment runs from the Mountain Laurel connector, which comes in from the west, to the Manzanita connector, which comes in from the east. Segment 10 Approximate Length : 285 feet 1. The segment has reasonable cross-slope along most of its length (photo 3) 2. Most of the current tread is in good shape. 3. Except for the south end, current grade is less than 10% 4. On the south end, there is a short, steep (>10% grade), fall line section. This section is cupped and lightly eroded (photo 2). 5. On the north end, there is a conifer with a broken branch blocking the trail (photo 4) 6. There is a slight drainage low to the west of the trail, in the center of the Open Space between the property boundaries. Photos : Steep section to armor or abandon 3 way connector Property Boundaries (magenta dashed) Drainage low trees as viewscape buffer The bulk of this segment is pretty good, as is. On the north end, the trail does get close to property lines. The alternative would be to move the alignment to the center of the Open Space. However, there is a slight drainage low which could be seasonally wet, which will not be a good location for the trail. In this same area, the property owners have a good viewscape buffer provided by trees. Given these 2 observations, the current alignment is acceptable. On the south end, there is a short fall line section of trail, where segments 8, 9 and 10 come together. Given the re-route of segment 8, this section will be hard to close, due to user efficiency issues. As such, our primary recommendation is to armor the tread surface in the same fashion as segment 2, so that it is viable for both foot and bike traffic. Our alternative recommendation would be to abandon the fall line segment, using the south triangle on the map. This will require buck and rail initially, and possibly planting some trees or shrubs to maintain a longer term closure. Photo 1 : Overview of Segment 10, looking northeast Photo 2 : Steep fall line section on SW end of trail, looking east Photo 3 : Good quality trail in center of segment Drainage low to the left of alignment Estimated Time and Resources to Implement 1. Keep the current alignment, except at the south end. Add a 3-way connector with good cross slope to link segments 8, 9 and 10, per the map 2. Widen the tread to 24 inches as need 3. De-berm where tread is cupped 4. Armor steep section connecting segments 9 and 10, per recommendations of segment 2 5. Remove broken tree limb on north end. 15 man-hours for tread re-habilitation, Trail Club volunteer time 10 man-hours to build 3 way connector, Trail Club volunteer time 20 man-hours for armoring section, Trail Club volunteer time Staff assistance to procure and deliver hardening materials ~ 100 sq. ft of rock or masonry pavers for hardening (2 ft wide x 50 ft long) Photo 4 : Fallen branch over primary trail at east end of alignment, new trail braid forming around west side of tree.

Segment 11 This segment runs from the Manzanita connector, which comes in from the east, to the connection with Mountain Laurel on the north end. Approximate Length : 500 feet Details Map and Descriptions : Segment 11 re-route alignment Property Boundaries (magenta dashed) Photos : Moving crossing east directly across from sidewalk ramp across Mtn. Laurel 1. The segment has several fall lines sections with erosion and deposition (photos 3 and 4) 3. The current grade is less than 10%, except the last 10-15 ft at the Mountain Laurel connection (photo 2). 4. There is a nice gateway feature in the middle of the segment through red rock outcroppings (photos 1 and 3) 5. The trail has good property boundary separation, except near the Manzanita connection. These properties do have good viewscape seperation via trees on their fence lines. The most signifiant problem with this segment are the fall line erosional segments. To make the trail more durable / sustainable, the trail needs to be re-routed per the map, which will create cross slope and shorter segments lengths, which will drain the trail better. The red rock gap / gateway feature will be preserved as this is a key feature for a good user experience. Along the fence line, the west portion will be left as is. If the alignment were moved further north towards Mountain Laurel, there is a slight drainage low that the tread would be in, leading to seasonally muddy conditions. This section to be left along the fence line has good viewscape protection via the trees planted along the fence (photo 4). At Mountain Laurel, the short steep section will be kept (photo 2). This embankment is continuous along the road and difficult to avoid. If a longer tread section were put in, the trail would feel inefficient to foot traffic and short cutting and re-establishment of this alignment is likely. Drainage low trees as viewscape buffer Photo 1 : View of red rock gap from Mountain Laurel. Current trail and re-route (green dashed) annotated. Looking southwest. Current trail 1. Re-route middle section of the trail, per the map, to create better cross-slope, shorter segments and better drainage. Build to new trail standards. 2. Widen the tread to 24 inches as need 3. De-berm where tread is cupped but not re-routed. 4. Use spoils from re-route to reclaim abandoned section of trail 5. Add 2 drainage dips on straight section east of Manzanita connection. 6. Move crossing east to be across from Mtn Laurel sidewalk ramp. Also creates cross slope approaching street. Photo 2 : Connection at Mountain Laurel. Steep section along road embankments.

Segment 12 Details Map and Descriptions : Lower Manor House trail Connection to North Hogback and Pasture trails (east side of road) Photos : Segment 12 This segment runs from Mountain Laurel to the connection (north side of road) to the Lower Manor house connector trail at North Ranch Rd. The current alignment is composed of 2 fall line segments. One segment runs along Manor House Road (photo 3) and one runs from Manor House Rd. to North Ranch Rd. (photo 4) Approximate Length : 480 feet re-route alignment 1. The current alignment is composed of 2 fall line segments (see description above) 3. The current grade exceeds 10% locally 4. There are no property boundaries on this segment 5. There are several abandoned braids on the north segment due to erosion. Segment 11 N. Hogback trail Pasture Trail Photo 1 : View of re-route from Lower Manor House connection. Looking southwest. Segment 11 This segment illustrates trail user s desire to have connected trails. This social trail creates closed loops to the Manor House trail, North Hogback trail and Pasture trails from the Manzanita social trails. As such, this is an important segment to bring into the system as part of this project. The two ends of these segments have a similar elevation. As such, they can be connected via a trail that roughly contours the hill. This will provide good cross slope along the entire length of the segment and avoid the erosional / sustainability issues of the current alignment. The west end can be tied into an existing ramp at the corner of Mountain Laurel and Manor House Rd. Lower Manor House trail N Ranch Rd. 1. Abandon the entire length of the current alignment and re-route, per the map, to create good cross-slope along the entire segment length. Photo 2 : View of re-route approaching Mountain Laurel. Looking west. 2. Build new alignment. 24 inches wide, per community new trail standards 3. Use spoils from re-route to reclaim the abandoned trail 4. Add signage on both sides of Mountain Laurel alerting users to crossing traffic. Photo 4 : Current fall line alignment approaching Lower Manor House trail and North Ranch Rd. Looking east.
