HomeMy WebLinkAbout7th & Aspen TIS Memo MONTANA | WASHINGTON | IDAHO | NORTH DAKOTA | PENNSYLVANIA 406.586.0277 tdhengineering.com 234 East Babcock Street Suite 3 Bozeman, MT 59715 MEMORANDUM Date: April 15, 2024 TDH Job No.: B24-008 To: Cody Flammond, PE - City of Bozeman Engineering Department From: Cody Croskey, PE Subject: 7th & Aspen Affordable Housing – Phases 1&2 Trip Generation and Traffic Impact Study Objectives The purpose of this memo is to provide average daily and peak hour trip generation estimates for Phase 1 & 2 of the 7th & Aspen Affordable Housing project and to clarify the objectives of the forthcoming Traffic Impact Study (TIS) for this project based on recent directives received from the City Engineering Department. Phases 1 and 2 will consist of demolishing a house/office and the Aaron’s retail store at 706 and 654 N. 7th Avenue and constructing two new 46 and 50-unit multifamily apartment buildings. The average day and peak hour vehicle trip generation values for the removed uses and proposed apartment buildings are attached along with the ITE land use description and peak hour trip generation sheets for reference. While the AM and PM peak hour trip generation values for this project are well below the 100 peak hour trip threshold typically used to determine if a traffic impact study is required for a development, the City Engineering Department is requiring that a traffic impact study be performed given the location and access off of N. 7th Ave. which is MDT jurisdiction (see email from Taylor Lonsdale attached). A formal TIS is currently being developed by the traffic consultant for this project to address the any specific objectives required by the City and MDT. The study will include an analysis of this development’s traffic projections and recommendations to address any resulting improvements needed for safety and operations of the adjacent street network. Please let me know if you have any questions or require any additional information in the meantime.

Access to individual dwelling units is through an outside building entrance, a lobby, elevator, and a set of hallways. Multifamily housing (low-rise) (Land Use 220), multifamily housing (high-rise) (Land Use 222), off- campus student apartment (mid-rise) (Land Use 226), and mid-rise residential with ground-floor commercial (Land Use 231) are related land uses. Land Use Subcategory Data are presented for two subcategories for this land use: (1) not close to rail transit and (2) close to rail transit. A site is considered close to rail transit if the walking distance between the residential site entrance and the closest rail transit station entrance is ½ mile or less. Additional Data For the six sites for which both the number of residents and the number of occupied dwelling units were available, there were an average of 2.5 residents per occupied dwelling unit. For the five sites for which the numbers of both total dwelling units and occupied dwelling units were available, an average of 96 percent of the total dwelling units were occupied. The technical appendices provide supporting information on time-of-day distributions for this land use. The appendices can be accessed through either the ITETripGen web app or the trip generation resource page on the ITE website (https://www.ite.org/technical-resources/topics/trip- and-parking-generation/). It is expected that the number of bedrooms and number of residents are likely correlated to the trips generated by a residential site. To assist in future analysis, trip generation studies of all multifamily housing should attempt to obtain information on occupancy rate and on the mix of residential unit sizes (i.e., number of units by number of bedrooms at the site complex). The sites were surveyed in the 1990s, the 2000s, the 2010s, and the 2020s in Alberta (CAN), California, District of Columbia, Florida, Georgia, Illinois, Maryland, Massachusetts, Minnesota, Montana, New Jersey, New York, Ontario (CAN), Oregon, Utah, and Virginia.

The building typically houses a single tenant. It is a location where affairs of a business, commercial or industrial organization, or professional person or firm are conducted. General office building (Land Use 710) is a related use. Additional Data Attorney office, mortgage company, financial advisor, insurance agency, home health care provider, and real estate company are examples of tenants included in the small office building database. The diversity of employer types results in a wide range in employee density in the database. Densities range from a high of 1,300 to a low of 240 square feet per employee with an overall average of nearly 600 square feet per employee (a value much larger than the average observed in a general office building study sites). In addition to the significant difference in employee density, small office buildings tend to be dominated by a single tenant (or very few) that are more service-oriented than a typical general office building. The result is more frequent and regular visitors and higher trip generation rates. The technical appendices provide supporting information on time-of-day distributions for this land use. The appendices can be accessed through either the ITETripGen web app or the trip generation resource page on the ITE website (https://www.ite.org/technical-resources/topics/trip- and-parking-generation/). The sites were surveyed in the 1980s and the 2010s in Alberta (CAN), California, Texas, and Wisconsin.

A variety store is commonly referred to as a “dollar store.” Items typically sold at a variety store include kitchen supplies, cleaning products, home office supplies, food products, household goods, decorations, and toys. The store can be stand-alone or located within a shopping plaza or strip retail plaza. Free-standing discount store (Land Use 815) is a related use.

We given the locaon we can’t waive a TIS for this. You will need to work with MDT on this one as it takes access from N 7th Ave which is MDT jurisdicon. We will generally fo llow MDT’s requirements related to a TIS for this one. A’er you talk with MDT on their requirements lets have a call to discuss further and ensure that MDT and City are aligned. You can reach out to Krisna Kilts (kkilts@mt.gov) and Ted Jones (tejones@mt.gov) at MDT to start the process. Krisna is the Bu/e District Traffic Engineer and Ted Jones is the Bozeman Maintenance Chief. Please let me know if you have any quesons.

Cody & Taylor, Please see the a/ached trip generaon esmates for the 7th & Aspen Affordable Mixed-Use Residenal Mulfamily project located at 706 & 726 N. 7th Avenue. The project phasing is shown below as discussed at the Pre-App Meeng on January 16th. - Phase 1 will consist of a new 46-unit residenal bu ilding at 706 N. 7th Avenue. - Phase 2 will consist of approximately 75 dwelling units and roughly 10,000 SF of undesignated commercial space at 726 N. 7th Avenue. 2 Phase 1 is expected to generate 15-AM and 15-PM new peak hour trips and Phase 2 is expected to add 54-AM and 56- PM peak hour trips, respecvely. As we start the Site Plan process for Phase 1, we would like to know if Phase 1 (and potenally both phases if Master Planned) qualify for a waiver from the TIS requirement based on the a/ached peak hour trip generaon.
