RFP P1113 Trail Design and Construction for Soapstone and Bobcat Natural Areas OPENING DATE 3 00 P M (Our Clock) March 19 2008 To all prospective bidders under the specifications and contract documents described above the following changes are hereby made ADD ➢ Scope of Services The specific deliverable products expected of the Contractor for each phase includes the following Final construction design and plan Estimated construction costs broken down by element (e g trail construction by machine trail construction by hand ADA trail switchback construction wooden bridges rehabilitation improvement/repair of existing two track as needed etc ) and total cost ➢ Phase II trails will use existing roads as much as possible but some new construction will be necessary for re routing around unsustainable alignments or for new connections We had specified 48"widths as the maximum for these b ut in reality they could be as wide as 96 depending on the ultimate uses (e g will serve as a trail and a maintenance vehicle access) ➢ Crusher fines for the ADA trails will need to be purchased and transported to the sites However at Soapstone if gravel is needed for any aspect of trail construction or improvement/repair of existing two track there is a supply available for use on site It may not be appropriate for all uses ➢ At Soapstone to the extent that the cattle tanks on site are operating the contractor may obtain water from them for trail construction purposes ➢ Map attached Please contact John D Stephen CPPO CPPB Senior Buyer at (970) 221 6777 with any questions

TRAILS PHASE 11 East Loop BOUNDARY \ / \ East Loop\ /\ PHASE 1 ROAD R6MuteS 16 mi S] I A Project Description Soapstone Prairie Soapstone Prairie Natural Area encompasses 18 728 acres of shortgrass prairie foothills shrubland cliffs and rock outcrops wetlands springs and prairie streams It is part of the Meadow Springs regional conservation focus area and an essential piece of the Laramie Foothills Mountains to Plains Project through which numerous partners are working to conserve nearly 200 000 acres of habitat working landscape and wildlife corridor between the Front Range and the High Plains The site is located approximately 25 miles north of Fort Collins and is bordered on the west by Larimer County s Red Mountain Open Space and on the north by the City of Cheyenne s Cheyenne Ridge Most of the eastern boundary is adjacent to the City of Fort Collins Utilities Meadow Springs Ranch The south edge is bordered by private properties Elevations on the site range from 6 000 feet on the eastern edge to 7 200 on the western boundary with the Red Mountain property Research conducted by the City of Fort Collins Natural Areas Program staff Colorado Natural Heritage Program Rocky Mountain Bird Observatory and other organizations has noted that Soapstone Prairie is home to globally rare ecosystems and prairie grasslands that offer high quality critical habitat for wildlife including pronghorn swift fox black tailed prairie dogs and mule deer Soapstone Prairie is also one of the last places in Colorado where elk still venture out onto the plains The land supports more than 130 species of birds including nesting golden eagles and burrowing owls prairie falcons ferruginous hawks long billed curlews and mountain plovers An amazing array of wetland and riparian systems including marshes, seeps springs and streams support the federally threatened Colorado butterfly plant and other imperiled plant species Areas of gnarled and aged jumpers centuries old ponderosa pines and even a relict stand of aspen are found in western sections of the property Culturally Soapstone Prairie is rich in human history dating back thousands of years The most significant cultural feature on Soapstone Prairie is the Lmdenmeier Archaeological Site a National Historic Landmark Recognized worldwide as one of the most well preserved and extensive Folsom occupations in the American West the history of the Lindenmeier Archaeological Site dates back over 12 000 years This site was excavated in the 1930 s by the Smithsonian Institution and the Colorado Museum of Natural History (now known as the Denver Museum of Nature and Science) and many of the artifacts collected at that time are archived and on display at the City of Fort Collins Museum The majority of the collection is at the Smithsonian Institution and a smaller collection is housed at the Denver Museum of Nature and Science In addition archaeological surveys conducted in the summers of 2006 and 2007 by researchers from Colorado State and Southern Methodist Universities documented numerous sites of other cultural interest on the property Currently Soapstone Prairie Natural Area is leased for cattle grazing Pedestrian use on open space lands is a staple recreation and many natural areas are designated as on trail only to help protect sensitive resources Because of its large size sensitive ecosystems critical wildlife habitats important cultural and archaeological sites and easily eroded geological features Soapstone Prairie will also be designated 7 as an on trail only natural area In addition on trail only use allows for cultural resources to remain in place and for the unique opportunity to interpret these features within the landscape in which they occur The City of Fort Collins has prepared a management plan for Soapstone Prairie Natural Area and a conceptual trail plan (see map Page 3) Both the management plan and conceptual trail plan have been reviewed by the public adjacent landowners Colorado Division of Wildlife and the City of Fort Collins Land Conservation Stewardship Board The conceptual trail plan for Soapstone Prairie currently includes two phases Phase I has three separate trail systems located in different areas of Soapstone Prairie Natural Area The trails will consist of four types of trails ADA hike hike/bike and all use There will be no motorized use trails Trail construction may need to accommodate livestock grazing (e g fences gates) Trail contractor will coordinate with the Natural Areas Program Land Manager regarding the grazing/ranching operations during design and construction Significant historical or pre historical artifacts may be encountered during trail construction in those cases construction in the area would need to be halted temporarily and an archaeological expert (to be provided under separate contract) would need to be contacted immediately The following map indicates the conceptual trails plan at full build out including approximately 39 miles of public access trails Actual locations of some trails will differ from the conceptual trail map below — final trail locations will be determined as crews work to find suitable terrain scenic view points and appropriate accessibility Hiking opportunities will be available on ail trails mountain biking will be available on all but the western loop near the Undenmeier site parking area and equestrians will have access to most trails in the southern two-thirds of the property A portion of trail at the Lindenmeier Site will be 100%ADA compliant Trail construction will be phased in over time Bobcat Ridae Bobcat Ridge Natural Area encompasses 2 600 acres of foothills grassland shrubland and ponderosa pine/Douglas fir forest The site is located west of Masonville Colorado and ranges from 5 000 to 7 200 foot elevations Portions of the site are adjacent to Roosevelt National Forest There are also three separate in holdings totaling 160 acres owned and managed by the U S Forest Service (USFS) The Bobcat Fire of 2000 burned about 2/3 of the forest on the site The site supports a diversity of wildlife species including elk mule deer bobcat mountain lion black bear turkey blue grouse coyote red-tailed hawk golden eagle and rattlesnake Bobcat Ridge also contains several known historical and pre historical sites including tips rings Approximately 16 miles of hiking biking and horseback riding trails were built in 2006 and 2007 and are open to public use The 4 mile Valley Loop Trail is all use with approximately 0 25 miles in crusher fine surface From the point where the crusher fine ends to the historic homestead cabin the trail grades are at or near ADA standards This portion of the trail will be converted to crusher fines Contract Phases Phase I of trail construction will consist of approximately 14 miles of 24 — 48 natural surface trail at Soapstone Prairie This work will include two loops from the future north parking lot in the vicinity of the Lindenmeier Site/ Roman Cabin area a connection from the northwest corner of Soapstone Prairie Natural Area to Red Mountain Open Space and a loop trail from the south parking lot SOAPSTONE NATURAL AREA TRAILS PHASES N PHASE' \\ / \_14 miles ROAD \\ NA BOUNDARY \/ Additionally 3 500 feet of ADA crusher fine trail will be built at Bobcat Ridge in the existing
