INTRODUCTION Benchmark Civil Engineering Services, Inc., (Benchmark) has been retained by Longacre Equine to evaluate the anticipated trip generation and access requirements for their proposed addition of 12 campsites. The site is located at 2101 CR 245, New Castle, CO. II. PROJECTED TRIP GENERATION The National standard to projecting the trip generation for a proposed use is the Institute of Transportation Engineers publication "Trip Generation" (ITE Trip Generation Manual) which is currently in its 10th Edition. The trip generation manual includes studies of numerous land uses including Use 416 Campground/Recreational Vehicle Park. This land use category is appropriate for the proposed Longacre Equinel2 campsites. The data available in the ITE Trip Generation Manual is limited to identifying the weekday AM and PM peak periods of projected trips. The table below indicates the projected trips for this site. Typical for many land uses, the peak hour of traffic is 15% of the total daily traffic so the table below indicates both the weekday AM and PM peak hours as well as the weekday average trips. The table also includes the trip generation associated with the three existing single family residential houses and the barn/boarding operation which are also accessed via the driveway. Any additional use of the driveway would be associated with the adjacent agricultural operations and would not occur on a daily basis. The table indicates that the heaviest traveled peak hour will be 10 trips and the average daily number of trips will be 73. * Based on peak hour being 15% of the Average Daily Traffic (ADT). ** Based on observations of facility operator 250009 Appendix A provides copies of the ITE Trip Generation Manual description and data, 1 Projected Trip Generation AM Peak Trips PM Peak Trips ADT Trips Enter Exit Total Enter Exit Total 2 3 5 3 2 5 34* 12 Campsites ITE Use #416 3 Ext.

ACCESS REQUIREMENTS The majority of the 73 projected daily trips per day will be automobile trips. The AASHTO Green Book includes typical vehicle path requirements and roadway width requirements for different classes of vehicles. The largest typical (widest and largest vehicle path) vehicles will be the single unit trucks which will service the portable toilet pump trucks. These vehicles would be classified as SU 40 trucks (single unit total length 40 feet). This vehicle is eight feet wide and has a turning path maximum width of 14.8 feet. Based on Table 7-107:Roadway Standards the site driveway would be classified as "Semi Primitive with eight foot wide lanes and two foot wide shoulders. The roadway should have a gravel surface. The existing roadways within the property can accommodate the path of a single unit truck or large passenger vehicle (van). Appendix B includes copies of the truck turning path for the SU -40 vehicle. The Garfield County Colorado Land Use and Development Article 7: Standards (Table 7-107 Roadway Standards) indicates that a Semi Primitive Driveway should provide eight foot wide lanes and two foot wide shoulders and that the roadway can have a gravel surface. The existing site driveway provides these requirements as does the existing internal roadway system. Any additional internal roadway segments will also meet this design standard. The design standards and proposed/existing features are included in the table below. 250009 2 Trip Generation and Site Access Report Longacre Equine Campsites February 28, 2019 Table 7-107: Roadway Standards Design Standards Simi Primitive Existing Design Capacity (ADT) 21-100 21-100 Minimum ROW Width (Feet) 40 40 Lane Width (Feet) 8 8 Shoulder Width (Feet) 2 2 Ditch Width (Feet) 4 4 Cross Slope 2% Chip/Seal 3% Gravel 3% Gravel Shoulder Slope 5% 5% Design Speed N/A N/A Minimum Radius (Feet) 50 50 Maximum % Grade 12 12 Surface Gravel Gravel 250009 3 APPENDIX A - ITE TRIP GENERATION MANUAL 10TH ED. Trip Generation and Site Access Report Longacre Equine Campsites February 28, 2019 Land Use: 416 Campground/Recreational Vehicle Park Description A campground and recreational vehicle park is a recreational site that accommodates campers, trailers, tents, and recreational vehicles on a transient basis. They are found in a variety of locations and provide a variety of facilities, often including restrooms with showers and recreational facilities, such as a swimming pool, convenience store, and Laundromat. Additional Data The sites were surveyed in the 1990s, the 2000s, and the 2010s in Rhode Island, Vermont, and Washington.

A typical site surveyed is a suburban subdivision. Additional Data The number of vehicles and residents had a high correlation with average weekday vehicle trip ends. The use of these variables was limited, however, because the number of vehicles and residents was often difficult to obtain or predict. The number of dwelling units was generally used as the independent variable of choice because it was usually readily available, easy to project, and had a high correlation with average weekday vehicle trip ends. This land use included data from a wide variety of units with different sizes, price ranges, locations, and ages. Consequently, there was a wide variation in trips generated within this category. Other factors, such as geographic location and type of adjacent and nearby development, may also have had an effect on the site trip generation. Single-family detached units had the highest trip generation rate per dwelling unit of all residential uses because they were the largest units in size and had more residents and more vehicles per unit than other residential land uses; they were generally located farther away from shopping centers, employment areas, and other trip attractors than other residential land uses; and they generally had fewer alternative modes of transportation available because they were typically not as concentrated as other residential land uses. Time -of -day distribution data for this land use are presented in Appendix A. For the six general urban/suburban sites with data, the overall highest vehicle volumes during the AM and PM on a weekday were counted between 7:15 and 8:15 a.m. and 4:00 and 5:00 p.m., respectively. For the two sites with Saturday data, the overall highest vehicle volume was counted between 3:00 and 4:00 p.m. For the one site with Sunday data, the overall highest vehicle volume was counted between 10:15 and 11:15 a.m. The sites were surveyed in the 1980s, the 1990s, the 2000s, and the 2010s in California, Connecticut, Delaware, Illinois, Indiana, Maryland, Minnesota, Montana, New Jersey, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Vermont, and Virginia.
