P1113 City of Fort Collins user experience than a wider trail corridor, which feels more like a roadway A wide trail corridor will decrease a user's desire to return to the trail system A narrower trail corridor constructed with the SWECO 480 will be more intimate and will blend better into the natural terrain, and will provide access with all terrain vehicles If certain sections of the reroutes must be accessed by vehicle by local land lessees, then ATI would accommodate this by cutting a wide enough bench to accommodate these vehicles This is not recommended by ATI because the overall trail experience will be less attractive to all user groups besides the ranchers ro � Ridge Top of the Proposed n ■ Arrowhead Trails Inc was incorporated in 1994 to assist agencies,

Trails, Inc has been instrumental in developing trail design and construction standards in the State of Colorado Colorado State Parks and the International Mountain Bicycling Association have incorporated our design and construction standards into their Trail Master Plans literature, and several published books Numerous agencies have utilized these standards in their requests for bid proposals ATI revised and developed the following standards based on USFS trail standards and its own experience working on numerous trail projects Designated Trails A designated trail is a trail that has been accepted, mapped, managed and improved to agency standards as a main route with a definable user use Designated trails have trailhead signs maps and improved corridors and surfaces unlike non -designated social trails Concrete, crusher fines and natural surface trails of various widths can be considered designated These trails serve a purpose and are considered permanent improvements to the property Designated trails help promote sustainability and resource protection and provide for specific recreational opportunities such as hiking, wildlife viewing mountain bike riding, and horseback riding Mountain Bike Trails Mountain bike specific trails or "purpose built trails" have changed the design of sustainable trail systems A mountain bike trail typically has a rolling and curving flow Mountain bikers prefer trails with low to moderate grades for ascending and higher grades for more challenging descents over stable rock Rolling grade dips and contouring curves promote water drainage, tend to curb the higher speeds associated with descents and provide an enjoyable kinesthetic experience to the mountain biker Equestrian Trails Equestrian trails should be designed with wider corridors, gradual curves, and a more direct alignment Equestrian trails are designed for the enjoyment of the rider and the horse An equestrian rider likes rides to scenic vistas, venous loop and destination opportunities with access to a water source Low grades and stable soils are desired for the most sustainable trail tread surface Social Trails Social trails are non -designated trails created by users for specific recreational uses of the property The tread surface of a social trail is typically very narrow and not well defined Some social trails along the shorelines of the lake get covered during periods of high water Braided social trails are not uncommon along the lake shoreline The most predominant type of social trails have been created by angling and boating access Social trails down to the lake tend to follow the fall line and can create erosion problems Social trails tend to develop where lake access points are not designated and improved Social trails show a need for a path to a desired recreational access point Some social trails may be recommended for improvement based on the need for access along the lake Social trails that are redundant or cause erosion by following bad alignments will be considered for closure and rehabilitation Social trails created by anglers are typically faint and experience limited and dispersed use These social trails will develop again if closed Angling social trails are generally considered reasonable for the use intended and should incur limited improvements and monitored Accessible Trails Many parks and open space areas are constructing accessible hard and soft surface trails as part of their trail systems Accessible trails have a firm, stable surface that meet the Americans with Disabilities Act (ADA) Accessibility Guidelines (ADAAG) Accessible trails should allow relatively easy access for wheelchairs strollers, and visually and mobility impaired users Accessible trails can be constructed from concrete asphalt or crusher fines to provide all weather routes for all visitors Accessible trails should be designed and constructed at less than an 8% grade to promote accessible use The trail tread should be free of obstacles excessive outsloping and cracks and gaps in the trail surfacing Sustamabie Trails "Sustamabdity on natural surface trail corridors is defined as the characteristic of a travel surface to support currently planned and future uses with minimal impact to the natural systems of the area Sustainable trails have negligible sod loss or movement while allowing the naturally occurring plant systems to inhabit the area, recognizing required pruning and eventual removal of certain plants over time Sustainable trails will not adversely affect the naturally occurring fauna Sustainable trail design will accommodate existing and future uses while only allowing appropriate uses The sustainable trail will require little rerouting and minimal maintenance over extended periods of time " - January 1991 National Park Service, Rocky Mountain Region Arrowhead Trails Inc wants to emphasizee that the construction of full bench trail construction consist of excavation of the trail tread to virgin soil Re -compaction of excavated material into the trail tread can compromise the integrity of the tread surface and may cause excessive erosion Avirgin cut with the disposal of spoils from the cut and the back slope cut is extremely important to ensure that the trail corridor appears natural and sustainable Trail Standards • Align trails using the natural topography of the land with a rolling contoured design • Ensure trail grades do not exceed % of the alignment cross slope • Align trails to ensure that water exits the trail tread often • Rolling grade dips should be the standard water drainage feature • Multi -use trails should be constructed with a 4-6 foot -wide trail tread • Singletrack trails should be constructed with an 18-36 inch -wide trail tread • The average maximum grade of the trail tread should not exceed 8% • The maximum grade of the trail tread should not exceed 10-15% • Trail grades should be checked with a clinometer during layout • Back slopes should be constructed between a 1 1 and 2 1 ratio • Trail tread outslopes should bebetween 6-1 % • Trail tread outslopes should be checked with a digital level •Adequate directional signage should be provided Trail System Standards • Provide sufficient trail map information so that a user with average ability can find the trailhead and have a reasonably good idea of where the trail leads • The trail system is signed well enough that an average user can follow the trail in all kinds of weather during its normal season of use The trail system has no unmarked unreasonable safety hazards that would not be expected by the average user of that type of trail during its normal season of use • Trail alignments are located in an area that minimizes its impact to native flora and fauna • Trail alignments do not unreasonably infringe upon the privacy of adjacent landowners • The trail system is reasonably free of logs brush, rocks, man-made hazards, and other obstructions that would prevent or deter use by users unless specifically designed for as a freestyle riding feature • Construction of bridges, ramps, retaining walls, steps and should be well designed stable, and properly constructed to assume no additional risk to the user A i i torusner Fines Trail in Buena Vista ARROWHEAD TRAILS, INC 11121 County Road 240 Salida, CO 81201 719-539-2817 Main Office 719-221-1049 Danna

RFP for Soapstone Prairie trail construction and design This implementation will complete the trails goal for the Bobcat Ridge Natural Area based on the trails master plan for the park r r Tp Ridge NA Existing Ridge to be Improved ATI has constructed numerous crusher fines trails throughout Colorado Our company has written literature and taught numerous agencies about the art of constructing these specialty trails ATI has continued to acquire specialized machinery to aid in the construction of crusher fines trails In 2007, ATI constructed a 7,500 linear foot crusher fines trail for Eagle Ranch in 3 weeks The purchase of a SWECO-RTC rubber track carrier with a mechanized dump bed further enhanced our ability to produce crusher fines trails quickly and efficiently The 3,500 linear foot extension of the ADA crusher fines trail will require a short reroute starting at bridge #3 to reduce the grades The SWECO 480 can quickly re -cut this portion of trail and prepare the bathtub excavation required to install the Mirafi landscaping weed prevention fabric and 4-6 inches of Buff, 3/8 inch minus crusher fines material used on the previously built CF trails at Bobcat Ridge ATI confirms that the Buff material obtained from Colorado Lein is the most appropriate material to continue the trail surfacing Despite its light color, the material compacts and wears well in the climate and conditions The existing CF trail constructed two seasons ago is still in excellent condition Colorado Lein had to prepare additional materials for the previous project and will most likely have to be contacted prior to construction to ensure that enough of the Buff material is crushed and available at the time of the project construction To properly install a CF trail the material must be placed, shaped, wetted to saturation, and properly compacted with a slight crown or outslope Grades should not exceed 8% for any distances and despite the short re-route section the remainder of the alignment will not need grade adjustments ATI was able to obtain sufficient water with our 500-gallon water tank and pump system to effectively wet the surfacing for compaction Shaping is very important to the process Without proper wetting, shaping, and compacting the trail surfacing, the trail surfacing has a potential to unravel and allow vegetation to grow within the trail itself Because the trail is aligned through grasslands, the possibility for this is higher, but can be controlled with weed control mitigations if necessary Poor wetting and compaction can also lead to

php?t=344100 I ATI has executed numerous design/build trail construction projects throughout Colorado Cheyenne Mountain State Park, Curt Gowdy State Park, and Bobcat Ridge Natural Area are examples of some of the mufti -use trail systems we have completed Recent Press Curt Gowdy Trail System was lust voted best new trail system by Men's Journal The Best of 2007 Issue The article following from the December Issue of Mountain Flyer Curt Gowdy► State Park, Cheyenne, WY This just -opened 17-mile loop is, for the time being, the best undis- covered singletrack in the West, with several natural rock features that lend to freerides (and some modest beginner trails, too) w at Bobcat Ridge NA M �JDLMV I ran at efoocat Ridge to be Improved ATI has constructed numerous crusher fines trails throughout Colorado Our company has written literature and taught numerous agencies about the art of constructing these specialty trails ATI has continued to acquire specialized machinery to aid in the construction of crusher fines trails In 2007, ATI constructed a 7,500 linear foot crusher fines trail for Eagle Ranch in 3 weeks The purchase of a SWECO-RTC rubber track carrier with a mechanized dump bed further enhanced our ability to produce crusher fines trails quickly and efficiently The 3,500 linear foot extension of the ADA crusher fines trail will require a short reroute starting at bridge #3 to reduce the grades The SWECO 480 can quickly re -cut this portion of trail and prepare the bathtub excavation required to install the Mirafi landscaping weed prevention fabric and 4-6 inches of Buff, 3/8 inch minus crusher fines material used on the previously built CF trails at Bobcat Ridge ATI confirms that the Buff material obtained from Colorado Lein is the most appropriate material to continue the trail surfacing Despite Its light color, the material compacts and wears well in the climate and conditions The existing CF trail constructed two seasons ago is still in excellent condition Colorado Lein had to prepare additional materials for the previous project and will most likely have to be contacted prior to construction to ensure that enough of the Buff material is crushed and available at the time of the project construction To properly install a CF trail the material must be placed, shaped, wetted to saturation, and properly compacted with a slight crown or outslope Grades should not exceed 8% for any distances and despite the short re-route section, the remainder of the alignment will not need grade adjustments ATI was able to obtain sufficient water with our 500-gallon water tank and pump system to effectively wet the surfacing for compaction Shaping is very important to the process Without proper wetting, shaping, and compacting the trail surfacing the trail surfacing has a potential to unravel and allow vegetation to grow within the trail itself Because the trail is aligned through grasslands, the possibility for this Is higher, but

all projects This is why our trails are so popular, not just sustainability put lust "pure fun to ride , run or hike " Just ask your staff and your visitors Numerous design and grade mistakes can be made during this stage ATI has extensive experience in this process We use a variety of design tools to achieve our goals GPS units, various mapping software programs, topographic maps, sod maps, aerial photographs, Google Earth, and clinometers ensure the most appropriate layout is obtained for the project Arrowhead Trails, Inc walked the proposed ADA portion of the trail and a portion of the hikers -only loop during the site visit on March e, 2008 The ADA trail alignment extends west from the north parking lot near the Lindenmeier Site/ Roman Cabin area The terrain in this location is very appropriate for the ADA trail alignment The portion of the hiker only trail that the bidders walked during the site visit began west of the ADA overlook The alignment ascended a drainage valley to the top of a flat ridge top, and then descending down a parallel drainage to the east ending near the cabin site The side slopes ranged from 20-30% The locations of the trail alignments have been determined by the city and they appeared appropriate However, the grades of the proposed layout of this trail are slightly steep for the side slopes The alignment will need to be realigned to incorporate a more sustainable trail tread ATI can bring the existing proposed alignment up to industry standards incorporating the design principals discussed below The Soapstone Prairie site trail plan recommends separate use trails This has become the norm for many other trail systems and works well at Bobcat Ridge Natural Area ATI understands this decision as a management tool for Soapstone Prairie A short portion of this trail is appropriate for a designated ADA portion of trail that extends west from the parking lot to a natural level overlook Mountain bikers and equestrians will be excluded from using the hiker only trails within the more intricate terrain Mountain bikes will be permitted on all other multi -use trails Equestrians will be restricted from the hiker only trails and the northern portion of the site Most of the equestrian use trails are located in the flatter, gentle terrain and should be accessed from the southern most parking lot This will reduce the impact of trailers traveling through the site Encourage equestrian use at one trailhead with ample trader parking and encourage hikers, runners and bikers at different trailhead with no trader access The expansive nature of the site leads land managers to expect hikers to generally stay in closer proximity to the northern parking lot Mountain bikers and equestrian will utilize trails that extend further Generally speaking, mountain bikers can travel farther distances than the other two user groups Equestrians are typically the most impacting user group, especially in wet sods, and will cover moderate to long distances A 24-inch wide trail tread is recommended for the hiker only trail ATI has the ability to build hand built trail with little disturbance, adequate drainage, rolling contour design, and appropriate grades based on the half rule and existing variable sideslopes Some portions of this trail may be built with the two mini -excavators ATI owns It will be similar to the Ginny Trail at Bobcat Natural Area Arrowhead Trails, Inc has built trails across gently sloping terrain with various construction techniques A single ditch or double ditch construction is one effective way to accommodate the limitations of flat terrain This method of construction utilizes the SWECO 480 by excavating material from the ditch construction on one or both sides and pulls and compacts the material into the center of the alignment This provides a slightly elevated trail tread and provides a place for excess water to drain to Using excess soils and rock for large rolling grade dips also enhances sustainabdity and the "fun factor" The City of Fort Collins has expressed the desire to retain the look of the ranch style double track prevalent on the site In many locations the double track is in good condition with the center of the trail alignment being slightly raised and vegetated in comparison to the compacted trail tread of the double track Arrowhead Trails, Inc would consider two additional construction techniques in addition to the previously mentioned ditch technique ATI can place a road base or crusher fines material along the double tracks only, raising the trail tread slightly to prevent the erosion and cupping of the trail from the higher impacts of equestrian and motor vehicles This could be installed using a splitter on the rear of the dump truck and would actually lay two separate tread alignments along the existing double track preserving its current ranch style double track, by keeping the vegetation in the center Looks greatl ATI could also enhance the existing ranch double track with minimal disturbance and minimal excavation techniques This would be accomplished with some rerouting and minimal regarding utilizing all terrain vehicles and specialized ATI constructed harrows The use of our specialized rock rake will also enhance this type of construction The City of Fort Collins will be responsible for the decision of which type of construction technique desired Each has its advantages and different degrees of costs and complications All can be executed by Arrowhead Trails, Inc with approval from the city Arrowhead Trails, Inc recommends that all reroutes of the existing trail alignment be constructed with a narrower trail corridor if vehicle access is not required The narrower corridor will be more aesthetic, less impact during construction and will provide a better user experience than a wider trail corridor, which feels more like a roadway A wide trail corridor will decrease a user's desire to return to the trail system A narrower trail corridor constructed with the SWECO 480 will be more intimate and will blend better into the natural terrain, and will provide access with all terrain vehicles If certain sections of the reroutes must be accessed by vehicle by local land lessees, then ATI would accommodate this by cutting a wide enough bench to accommodate these vehicles This is not recommended by ATI because the overall trail experience will be less attractive to all user groups besides the ranchers Ridge Top of the Proposed Hikers Only Trail rovi Proposed Alignment of the Eastern Loop Arrowhead

Parks and the International Mountain Bicycling Association have incorporated our design and construction standards into their Trail Master Plans, literature, and several published books Numerous agencies have utilized these standards in their requests for bid proposals ATI revised and developed the following standards based on USFS trail standards and its own experience working on numerous trail projects Designated Trails A designated trail is a trail that has been accepted, mapped, managed and improved to agency standards as a main route with a definable user use Designated trails have trailhead signs, maps, and improved corridors and surfaces unlike non -designated social trails Concrete crusher fines, and natural surface trails of various widths can be considered designated These trails serve a purpose and are considered permanent improvements to the property Designated trails help promote sustainability and resource protection and provide for specific recreational opportunities such as hiking, wildlife viewing, mountain bike riding, and horseback riding Mountain Bike Trails Mountain bike specific trails or "purpose built trails" have changed the design of sustainable trail systems A mountain bike trail typically has a rolling and curving flow Mountain bikers prefer trails with low to moderate grades for ascending and higher grades for more challenging descents over stable rock Rolling grade dips and contouring curves promote water drainage, tend to curb the higher speeds associated with descents, and provide an enjoyable kinesthetic experience to the mountain biker Equestrian Trails Equestrian trails should be designed with wider corridors, gradual curves, and a more direct alignment Equestrian trails are designed for the enjoyment of the rider and the horse An equestrian rider likes ndes to scenic vistas, various loop and destination opportunities with access to a water source Low grades and stable soils are desired for the most sustainable trail tread surface Social Trails Social trails are non -designated trails created by users for specific recreational uses of the property The tread surface of a social trail is typically very narrow and not well defined Some social trails along the shorelines of the lake get covered during periods of high water Braided social trails are not uncommon along the lake shoreline The most predominant type of social trails have been created by angling and boating access Social trails down to the lake tend to follow the fall line and can create erosion problems Social trails tend to develop where lake access points are not designated and improved Social trails show a need for a path to a desired recreational access point Some social trails may be recommended for improvement based on the need for access along the lake Social trails that are redundant or cause erosion by following bad alignments will be considered for closure and rehabilitation Social trails created by anglers are typically faint and experience limited and dispersed use These social trails will develop again if closed Angling social trails are generally considered reasonable for the use intended and should incur limited improvements and monitored Accessible Trails Many parks and open space areas are constructing accessible hard and soft surface trails as part of their trail systems Accessible trails have a firm, stable surface that meet the Americans with Disabilities Act (ADA) Accessibility Guidelines (ADAAG) Accessible trails should allow relatively easy access for wheelchairs strollers, and visually and mobility impaired users Accessible trails can be constructed from concrete, asphalt or crusher fines to provide all weather routes for all visitors Accessible trails should be designed and constructed at less than an 8% grade to promote accessible use The trail tread should be free of obstacles, excessive outsloping, and cracks and gaps in the trail surfacing Sustainabis Trails "Sustainabdity on natural surface trail comdors is defined as the charactenstic of a travel surface to support currently planned and future uses with minimal impact to the natural systems of the area Sustainable trails have negligible sod loss or movement while allowing the naturally occumng plant systems to inhabit the area, recognizing required pruning and eventual removal of certain plants over time Sustainable trails will not adversely affect the naturally occumng fauna Sustainable trail design will accommodate existing and future uses while only allowing appropnate uses The sustainable trail will require little rerouting and minimal maintenance over extended penods of time " - January 1991 National Park Service, Rocky Mountain Region Arrowhead Trails, Inc wants to emphasizee that the construction of full bench trail construction consist of excavation of the trail tread to virgin sod Re -compaction of excavated material into the trail tread can compromise the integrity of the tread surface and may cause excessive erosion Awrgin cut with the disposal of spoils from the cut and the back slope cut is extremely importantto ensure that the trail corridor appears natural and sustainable Trail Standards • Align trails using the natural topography of the land with a rolling contoured design • Ensure trail grades do not exceed % of the alignment cross slope • Align trails to ensure that water exits the trail tread often • Rolling grade dips should be the standard water drainage feature • Multi -use trails should be constructed with a 4-6 foot -wide trail tread • Singletrack trails should be constructed with an 18-36 inch -wide trail tread • The average maximum grade of the trail tread should not exceed 8% • The maximum grade of the trail tread should not exceed 10-15% • Trail grades should be checked with a clinometer during layout • Back slopes should be constructed between a 1 1 and 2 1 ratio • Trail tread outslopes should bebetween 6-1 % • Trail tread outslopes should be checked with a digital level -Adequate directional signage should be provided Trail System Standards • Provide sufficient trail map information so that a user with average ability can find the trailhead and have a reasonably good idea of where the trail leads • The trail system is signed well enough that an average user can follow the trail in all kinds of weather during its normal season of use • The trail system has no unmarked unreasonable safety hazards that would not be expected by the average user of that type of trail during its normal season of use • Trail alignments are located in an area that minimizes its impact to native flora and fauna • Trail alignments do not unreasonably infringe upon the privacy of adjacent landowners • The trail system is reasonably free of logs, brush, rocks, man-made hazards, and other obstructions that would prevent or deter use by users unless specifically designed for as a freestyle riding feature • Construction of bridges, ramps, retaining walls, steps and should be well designed, stable, and properly constructed to assume no additional risk to the user with weed control mitigations if necessary Poor wetting and compaction can also lead to separation of materials, and ultimately leads to the fines sifting to bottom and the gravel floating to the top, leaving a surface that is "not stable and

Lindenmeler/Roman Loop Trails The eight miles of 12-24" natural surface trail can be constructed with a combination of processes Areas with steeper side slopes will be constructed by hand and areas with slight side slopes can be constructed more efficiently with our mini -excavators, without disturbing anything but the trail Both types of construction will be minimal impact, similar to Bobcat techniques The construction can be completed by the timelines set forth in the RFP ATI is confident, the Phase I trails can be completed by the end of 2008 and guarantees to be completed by April 2009 deadline The terrain and mild winter precipitation of the area will allow for construction well into the fall and winter season If work continues into 2009, it will remain our highest priority, until 100% complete Northwest Red Mountain Connection This 1 2 miles of 24-48" natural surface trail can easily be constructed by the end of 2008 Southwest Loop System This 4 5 mile 24-48" natural surface trail can be constructed by the April 2009 deadline Most likely this section could be completed sooner than this Bobcat Ridge Natural Area This 3,500 linear foot improvement could be completed in three weeks ATI can begin this portion of Phase I in the fall of 2008 Lindenmeler ADA Trail This 1600 Inver foot crusher fines trail will take two weeks to complete ATI can begin this portion of Phase I in the fall of 2008 This trail is to be built at the minimum ADA trail corridor width of 36" Phase II West Connection This 3 5 mile connection to the Red Mountain can be constructed in the Spring of 2009, or winter d weather permits The construction consists of a combination of double track road improvements and new re-route construction ATI recommends the new construction to be 48" natural surface trail unless vehicle access will be required The city will have to determine the use of this new trail and notify the contractor in a timely manner SW Connector This 2-3 miles of new construction can be added to the construction schedule for the West Connection and completed in the Spring of 2009 North Road This 5 mile portion of trail follows the existing double track Improvements include regarding and some needed re-routes to be determined during the design phase The construction can begin in the Spring of 2009, or winter if weather permits East Loop System These trails will follow existing double track roads where sustainable and incorporate some short re-routes recommended by the contractor Several construction techniques described in the Project Approach section above The construction/reconstruction can begin in the Spring of 2009 and be completed by Summer 2009 References Company Resume Arrowhead Trails, Inc is an S-corporation incorporated in the

projects This is why our trails are so popular, not just sustainabdity put just "pure fun to ride, run or hike " Just ask your staff and your visitors Numerous design and grade mistakes can be made during this stage ATI has extensive experience in this process We use a variety of design tools to achieve our goals GPS units, various mapping software programs, topographic maps, sod maps, aerial photographs, Google Earth, and clinometers ensure the most appropriate layout is obtained for the project Arrowhead Trails, Inc walked the proposed ADA portion of the trail and a portion of the hikers -only loop during the site visit on March 51i 2008 The ADA trail alignment extends west from the north parking lot near the Undenmeier Site/ Roman Cabin area The terrain in this location is very appropriate for the ADA trail alignment The portion of the hiker only trail that the bidders walked during the site visit began west of the ADA overlook The alignment ascended a drainage valley to the top of a flat ridge top, and then descending down a parallel drainage to the east ending near the cabin site The side slopes ranged from 20 30% The locations of the trail alignments have been determined by the city and they appeared appropriate However, the grades of the proposed layout of this trail are slightly steep for the side slopes The alignment will need to be realigned to incorporate a more sustainable trail tread ATI can bring the existing proposed alignment up to industry standards incorporating the design principals discussed below The Soapstone Prairie site trail plan recommends separate use trails This has become the norm for many other trail systems and works well at Bobcat Ridge Natural Area ATI understands this decision as a management tool for Soapstone Prairie A short portion of this trail is appropriate for a designated ADA portion of trail that extends west from the parking lot to a natural level overlook Mountain bikers and equestrians will be excluded from using the hiker only trails within the more intricate terrain Mountain bikes will be permitted on all other multi -use trails Equestrians will be restricted from the hiker only trails and the northern portion of the site Most of the equestrian use trails are located in the flatter, gentle terrain and should be accessed from the southern most parking lot This will reduce the impact of trailers traveling through the site Encourage equestrian use at one trailhead with ample trailer parking and encourage hikers runners and bikers at different tradhead with no trader access The expansive nature of the site leads land managers to expect hikers to generally stay in closer proximity to the northern parking lot Mountain bikers and equestrian will utilize trails that extend further Generally speaking mountain bikers can travel farther distances than the other two user groups Equestrians are typically the most impacting user group, especially in wet sods, and will cover moderate to long distances A 24-Inch wide trail tread is recommended for the hiker only trail ATI has the ability to build hand built trail with little disturbance, adequate drainage, rolling contour design, and appropriate grades based on the half rule and existing variable sideslopes Some portions of this trail may be built with the two mini -excavators ATI owns It will be similar to the Ginny Trail at Bobcat Natural Area Arrowhead Trails, Inc has built trails across gently sloping terrain with various construction techniques A single ditch or double ditch construction is one effective way to accommodate the limitations of flat terrain This method of construction utilizes the SWECO 480 by excavating material from the ditch construction on one or both sides and pulls and compacts the material into the center of the alignment This provides a slightly elevated trail tread and provides a place for excess water to drain to Using excess sods and rock for large rolling grade dips also enhances susta inability and the "fun factor" The City of Fort Collins has expressed the desire to retain the look of the ranch style double track prevalent on the site In many locations the double track is in good condition with the center of the trail alignment being slightly raised and vegetated in comparison to the compacted trail tread of the double track Arrowhead Trails, Inc would consider two additional construction techniques in addition to the previously mentioned ditch technique ATI can place a road base or crusher fines material along the double tracks only, raising the trail tread slightly to prevent the erosion and cupping of the trail from the higher impacts of equestrian and motor vehicles This could be installed using a splitter on the rear of the dump truck and would actually lay two separate tread alignments along the existing double track preserving its current ranch style double track, by keeping the vegetation in the center Looks greatl ATI could also enhance the existing ranch double track with minimal disturbance and minimal excavation techniques This would be accomplished with some rerouting and minimal regarding utilizing all terrain vehicles and specialized ATI constructed harrows The use of our specialized rock rake will also enhance this type of construction The City of Fort Collins will be responsible for the decision of which type of construction technique desired Each has its advantages and different degrees of costs and complications All can be executed by Arrowhead Trails, Inc with approval from the city Arrowhead Trails, Inc recommends that all reroutes of the existing trail alignment be constructed with a narrower trail corridor if vehicle access is not mq u� rail The narrower corridor will be more aesthetic, less impact during construction and will provide a better
