The following items comprise the infrastructure deficiencies associated with the TEDD. TRANSPORTATION 1. Bozeman Municipal Code (BMC) 38.400 requires the following upgrades to the transportation system in the vicinity of the proposed area: a. Cedar Street is classified as a Local Street. Cedar Street must be constructed to a local street standard per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including complete construction of the road with minimum 31-feet width curb-to-curb and sidewalk on both sides of the street. b. L Street is classified as Collector Street. L Street must be constructed to a collector standard within the boundaries of the Blight area per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including complete construction of the road with minimum 48-feet width curb-to-curb and sidewalk on both sides of the street. Additional right-of-way must be obtained to construct the necessary improvements. Lastly, safety improvements are required at the railroad crossing to convert the railroad crossing at L Street to a Quiet Zone. c. Front Street is classified as a Local Street. Front Street must be constructed to a local street standard within the boundaries of the Blight area per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including complete construction of the road with minimum 31-feet width curb-to-curb and sidewalk on both sides of the street. Additional right-of-way is needed to construct this street at some locations. d. Birch Street is classified as a Local Street. Birch Street must be constructed to a local street standard per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including complete construction of the road with minimum 31-feet width curb-to-curb and sidewalk on both sides of the street. Additional right-of-way is needed to construct this street. e. N Broadway Avenue is classified as Collector Street. N Broadway must be constructed to a collector standard within the boundaries of the Blight area per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including construction of streets, curb and gutter, and sidewalk on both sides of the street where not already constructed. f. E Avocado Street is classified as Collector Street. E Avocado Street must be constructed to a collector standard within the boundaries of the Blight area per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including construction of a portion of the street, curb and gutter where not yet constructed, and sidewalk where not yet constructed on each side of the street where. g. Pear Street is classified as a Local Street. Pear Street must be constructed to a local street standard per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including complete construction of the road with minimum 31-feet width curb-to-curb and sidewalk on both sides of the street. h. Bohart Lane is classified as a Local Street. Bohart Lane must be constructed to a local street standard per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including complete construction of the road with minimum 31-feet width curb-to-curb and sidewalk on both sides of the street. i. E. Oak Street is classified as a Local Street. E. Oak Street must be constructed to a local street standard per the City of Bozeman Design Standards and Specifications Policy and Bozeman Transportation Master Plan including complete construction of the road with minimum 31-feet width curb-to-curb and sidewalk on both sides of the street. j. Bond Street and Gold Avenue do not have sidewalks, and sidewalks must be constructed to connect the pedestrian infrastructure on these streets. SANITARY SEWER 1. BMC 38.410.070 requires sanitary sewer mains to be installed to serve the area located in the proposed TEDD, and the mains must be installed in accordance with the City of Bozeman Design Standards and Specifications Policy as well as the City Wastewater Collection Facilities Plan Update. Much of the area located in the proposed TEDD does not have any sanitary sewer mains to provide sanitary service. The City of Bozeman Wastewater Collection Facilities Plan calls for a 30-inch diameter sanitary sewer main to be installed from Rouse Avenue at the intersection with Bond Street, extending down Bond Street and Gold Avenue to L Street and continuing to the southeast on Bohart Lane. 2. BMC 38.410.070 requires sanitary sewer mains to be installed to serve development where there is currently no sanitary sewer service. Minimum 8-inch diameter sanitary sewer mains would be required at multiple locations through the proposed TEDD area to provide sanitary sewer service depending on future development plans. In general, sanitary sewer mains would be located within street right-of-way unless it is not possible to locate mains in the streets. 3. BMC 38.410.060 requires easements for all sanitary sewer mains where not located in public right-of-way. Easements are needed from L Street to the existing sanitary sewer main in Gold Avenue to allow for the proposed sanitary sewer trunk main to serve this area. WATER 1. BMC 38.410.070 requires water mains to be installed to serve the area located in the proposed TEDD. Water mains must be constructed to the standards defined in the City of Bozeman Design Standards and Specifications Policy and the City of Bozeman Water Facility Plan. Minimum 8-inch diameter water mains would be required at multiple locations through the proposed TEDD area to provide potable water service depending on future development plans. In general, water mains would be located within street right-of-way unless it is not possible to locate mains in the streets. 2. BMC 38.410.060 requires easements for all water mains where not located in public right-of- way. FLOODPLAIN 1. The recently updated Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) will be officially adopted into local floodplain regulations (Division 38.600 BMC) within the next 12 months. These maps will be used for project planning purposes given the likelihood that development will occur after the new maps are adopted. These updated maps place a portion of the proposed TEDD area into the floodway and 100-year floodplain. BMC 38.600.240.A.1 prohibits new construction of any residential, commercial or industrial structure in the floodway. Compliance options are limited to siting all building improvements outside of the floodway, or seeking and receiving official FEMA revision of the floodway. Any allowable encroachments into the floodway must show no-rise in the Base Flood Elevation. If the no-rise standard cannot be met then official FEMA revision of the BFE and resultant flood hazard mapping will be required through the CLOMR/LOMR process. Any encroachment into Zone AE as shown on the new FIRMs must be authorized under a City of Bozeman Floodplain Permit. 2. BMC 38.600.210.A.4.c requires utility transmission lines carrying toxic or flammable materials to be buried at least two times the calculated depth of scour. STORMWATER 1. The City Design Standards and Specifications Policy (DSSP) Section (A)(4) Water Quality states a drainage system must be installed with all future development including post-construction storm water management controls that are designed to infiltrate, evapotranspire, and/or capture for reuse the post-construction runoff generated from the first 0.5 inches of rainfall from a 24-hour storm preceded by 48 hours of no measurable precipitation. For projects that cannot meet 100% of the runoff reduction requirement, the remainder of the runoff from the first 0.5 inches of rainfall must be either: a. Treated onsite using post-construction storm water management control(s) expected to remove 80 percent total suspended solids (TSS); b. Managed offsite within the same sub-watershed using post-construction storm water management control(s) that are designed to infiltrate, evapotranspire, and/or capture for reuse; or c. Treated offsite within the same subwatershed using post-construction storm water management control(s) expected to remove 80 percent TSS. 2. DSSP Section (C) Water Quantity requires on-site detention with release rates limited to predevelopment runoff rates. Retention ponds must be sized based on a 10-year, 2-hour storm intensity. WATER RIGHTS 1. BMC 38.410.130 (A) (1) states Cash-in-lieu (CIL) of water rights must be provided prior to any future development approval, so the City can purchase water rights for new source water supply to offset new demands in the proposed TEDD area. ENVIRONMENTAL 1. Any development on the subject property will be evaluated by the City to ensure that proposed development and land uses in the application are consistent with permissible uses for this brownfield land under the EPA document to protect health, welfare, and safety. The EPA imposed Institutional Controls on Real Property per Document No. 2554371, or amended.
