Main Street, Suite 101 Bozeman, Montana 59715 (406) 556-7100 MONTANA STATE UNIVERSITY INNOVATION CAMPUS PHASE I—INFRASTRUCTURE IMPROVEMENTS BOZEMAN,MONTANA ENGINEERING REPORT EDA Grant Application Data Introduction: A.I. Investment(Project)Region The Region where the project is located: This proposed project, the MSU Innovation Campus, is located in the southwestern region of Montana within the Northern Rocky Mountain Economic Development District, in Bozeman, Montana, and within Gallatin County, State of Montana. That district encompasses the two counties of Park and Gallatin. However, the service area of the Bozeman-Belgrade-Livingston area extends nearly to Butte to the west and Billings to the east and Helena to the north. This regional hub is best exemplified, perhaps, by the fact that the Gallatin Airport has the highest number of passengers boarding annually within the State of Montana. The Region that will benefit from the project: Though the project is located within the City of Bozeman, adjacent to the campus of Montana State University, this project will potentially have a much wider benefit geographically than the region identified above. As one of the primary research institutions of the State of Montana, the benefit of MSU's mission extends well beyond this region to the borders of Montana and beyond. For example, as an agricultural research institution, crops are grown every year in Montana and other states that have benefitted from research accomplished by MSU researchers. This example can be expanded, with direct ties to MSU programs related to the fields of bio-science, photonics and in scores of other areas. As an educational institution, MSU provides highly trained, educated workforce across the spectrum. For example, MSU is the home of the Montana Manufacturing Extension Center (MMEC) which got its start with the EDA-funded University Technical Assistance Program (UTAP), a highly successful University Center. Though the project is located within Bozeman, the proposed MSU Research Park will have beneficial economic impacts well beyond the immediate geographic region. A.2. Investment(Project)Description General Project Description: This project consists of the installation of all infrastructure required to develop a university-related research park, the Montana State University Innovation Campus, on 41.98 acres adjacent to Montana State University and located in Gallatin County within the State of Montana. The components of the proposed project included within this application are: Municipal Water Services: New 8" pipe, consisting of 1,773 lineal feet, will be installed in Technology Boulevard. The new pipe will connect to the existing 8" terminations at each existing Technology Boulevard termination(east and west). The new Technology Boulevard water main will involve a water Page I of 14 MONTANA STATE UNIVERSITY INNOVATION CAMPUS PHASE I—INFRASTRUCTURE IMPROVEMENTS BOZEMAN,MONTANA ENGINEERING REPORT crossing under the unnamed tributary of Catron Creek. New 8" service stubs will be installed at 8 locations. Each 8" stub will terminate with a 2" blowoff assembly. New 6" fire hydrant assemblies will be installed at 4 locations. The new water lines are designed to meet DEQ Circular-1 requirements and City of Bozeman modifications for water transmission. Municipal Sewer Services: New 8" SDR35 PVC will be installed in Technology Boulevard and within a 30' utility easement that is located between Technology Boulevard and College Street aligned north and south. Per City of Bozeman design standards, a 12' all-weather access road will be provided within the easement. There are two proposed points of connection to the City sewer mains. One located at the current east termination of Technology Boulevard and the other will be the existing main in College Street. In total 1707 lineal feet of 8" pipe will be installed, along with 14 manholes. The new sewer lines are designed to meet DEQ Circular-2 requirements and City of Bozeman modifications. Streets, Curbs and Gutter: Technology Boulevard length is approximately 1,761 lineal feet and South 27`h Street is approximately 768 lineal feet. Technology Boulevard has a 60' right-of-way having two different widths: 35 feet wide for 1,241 lineal feet and 38 feet wide for 520 lineal feet. South 27'h Street has a 80' right-of-way and driving lanes that are separated by a 15' boulevard for 768 lineal feet. Storm Sewer/Drainage: New 434 lineal feet of 18" and 372 lineal feet of 24" pipe will be installed in Technology Boulevard and South 271h Street. In addition, four City of Bozeman standard curb inlets, four City of Bozeman standard combination curb inlets, and three storm manholes will be installed. Three detention ponds areas will be graded. Other components: A/E services will include typical construction administration services consisting of: construction inspection, shop drawing reviews, payment applications reviews, and typical services. In addition, the services will include construction surveying. Dry Utilities: Provision of needed electrical, natural gas, and fiber optics distribution systems will not be included within the scope of work of this application. Instead, funds will be provided by the state of Montana to install this infrastructure which will be coordinated by the A/E firm during construction phases. The following pages of the report are formatted for a concurrent review by the Montana Department of Environmental Quality(MDEQ)and the City of Bozeman(COB). JaA Page 2 of 14 MONTANA STATE UNIVERSITY INNOVATION CAMPUS PHASE I—INFRASTRUCTURE IMPROVEMENTS BOZEMAN,MONTANA ENGINEERING REPORT The purpose of this report is to outline the infrastructure and improvements that must be completed for the Montana State University Innovation Campus (MSUIC) connections to the City water and sewer utilities in College Street and Technology Boulevard. At full development the campus will consist of 41.98 acres of buildings, parking, landscaped areas, wetlands, streets, and sidewalks and will serve as a university related research park. A master site plan has been completed to show the MSUIC vision for the property and is attached to this report. The property will be developed in multiple phases as tenants are established. This first phase of construction will only consist of the major infrastructure which includes: water, sanitary sewer, storm sewer, gas, power, telephone, streets and sidewalks (South 27th Street and Technology Boulevard), landscaping, and trails. Site plans for the roads and trails have been included with this report. The project is located on the 41.98 acre Tract C-IA of the Amended Plat of West College Minor Subdivision No. 195 located in the Northwest 1/4 and Northeast 1/4, Section 14, Township 2 South, Range 5 East, P.M.,M., City of Bozeman, County of Gallatin, State of Montana. More specifically, the project is located between College and Garfield streets and between Bozeman Gateway Subdivision and Advanced Technology Park. The property is zoned BP (Business Park). Per communications with the City, the property, which also includes the unnamed tributary of Catron Creek, is not within a mapped floodplain. The site is comprised of native grasses and wetlands, an un-named tributary of Catron Creek, an existing gravel roadway, and buildings. The buildings will be demolished before the first phase of construction. The existing buildings were originally used by the Montana State University Agriculture Department. The wetlands within the property have been delineated and are shown on the plans. A report was prepared by Hyalite Environmental, LLP titled "Wetland Delineation Report MSU Innovation Campus Bozeman, MT" dated November 2013. This report can be provided upon request. In addition to the wetland delineation report, Hyalite also prepared an environmental narrative. A nationwide permit will be required for the construction activities that disturb wetlands, specifically the crossing of Technology Boulevard. In keeping with the historic drainage patterns on the property, stormwater will be conveyed to the wetlands at pre-development flow rates. The wetlands are an important feature on the property that provide a means of sediment, nutrient, and pollution removal; and flood control. The wetlands are also a significant feature that the City wants to see implemented into the design of the site. Wetlands and creek corridors are very important to the community and need to, as much as possible, be kept in their natural aesthetic nature. The wetlands corridor, which includes the watercourse setbacks, consists of approximately 13%of the entire site area. The following project summary provides an overview of the preferred alternatives developed through addressing project goals and objectives, design requirements, MSUIC requirements, and City coordination during the design of the project. 1. Transportation Network— approximately 2,500 linear feet of roadway will be constructed. The new roads will consist of installing new roadway between the current terminations of Technology Boulevard, between the Bozeman Gateway and Advanced Technology Park Page 3 of 14 MONTANA STATE UNIVERSITY INNOVATION CAMPUS PHASE I—INFRASTRUCTURE IMPROVEMENTS BOZEMAN,MONTANA ENGINEERING REPORT subdivisions. Additionally, a portion of South 271' Street will be installed between the new portion of Technology Boulevard and the existing Garfield Street. 2. Water System Transmission - new 8"pipe will be installed in Technology Boulevard. The new pipe will connect to the existing 8"terminations at each existing Technology Boulevard termination(east and west). The new Technology Boulevard water main will involve a water crossing under the unnamed tributary of Catron Creek. The new water lines are designed to meet DEQ Circular-1 requirements and City of Bozeman modifications for water transmission. 3. Sanitary System Conveyance — new 8" SDR35 PVC will be installed in Technology Boulevard and within a 30' utility easement that is located between Technology Boulevard and College Street aligned north and south. Per City of Bozeman design standards, a 12' all- weather access road will be provided within the easement. There are two proposed points of connection to the City sewer mains. One located at the current east termination of Technology Boulevard and the other will be the existing main in College Street. The new sewer lines are designed to meet DEQ Circular-2 requirements and City of Bozeman modifications. 4. Stormwater Structures—See Storm Water Report. The new water main includes approximately 1750 linear feet of 8" CL51 DIP AWWA 151, fire hydrant assemblies, gate valves, bends and fittings, and 8"stubs w/2"blowoff assemblies. Also, in coordination with the future College Street widening project in the spring of 2015, we are requesting the City provide 8"stubs off the College Street main to serve future pad sites on the north end of the MSU Innovation Campus, to prevent any future street cuts. Additionally, future MSUIC pad sites near the south boundary will be serviced by the Garfield Street 8"main. Street cuts will be required for any Garfield Street services. The two sewer extensions include the installation of approximately 1709 and 224 linear feet, respectively. One extension will begin at a new"doghouse"manhole on the existing 15"main in College Street and extend south in a 30' utility easement for approximately 734 linear feet to Technology Boulevard and then west approximately 975 linear feet. The other extension will begin at easterly termination of Technology Boulevard and extend to the west approximately 224 linear feet. No service wyes will be installed. However, 8"stubs will be provided at various manholes to be extended into development areas as tenants are established and sites designed. The format of the remainder of this report follows Circular DEQ-1, Chapter 8 and Circular DEQ-2, Chapter 30, and the corresponding applicable Circular sections for information contained in the Contract Documents. This engineering report demonstrates construction document compliance with Circular DEQ-1, Chapter 8 "Transmission Mains, Distribution Systems, Piping & Appurtenances" for the water connection, and Circular DEQ-2,Chapter 30"Design of Sewers"for the sanitary sewer connection.

Page 9 of 14 MONTANA STATE UNIVERSITY INNOVATION CAMPUS PHASE I—INFRASTRUCTURE IMPROVEMENTS BOZEMAN,MONTANA ENGINEERING REPORT 32 DESIGN CAPACITY AND DESIGN FLOW Per a letter from the City of Bozeman Engineering Department, the existing sewers in both College Street(15" main) and Technology Boulevard(8"main) have the capacities for the proposed MSUIC flows. The letter has been provided with this report. Sewage from MSU Innovation Campus will be conveyed to City mains at two different locations. The contributing area to the Technology Drive connection point consists of approximately 4.7 acres with the College Street connection having approximately 24.2 acres. Using the BP zoning designation for the property, Table V-1 in the City of Bozeman Design Standards Manual, was used to select a design flow rate of 960 gallons per acre per day for the development. The average daily flows for the development were calculated by delineating the MSUIC property into contributing areas based on where sewage would be conveyed. Using the contributing areas and the design flow rate and also the 150 gallons per acre per day infiltration rate, average daily flows were calculated for each respective area.
