This work is to be done as a part of the Midtown Urban Renewal District term contract for architectural and engineering services. We understand that the goal of this project generally is to determine the size and extent of wastewater infrastructure required to serve the Midtown and Downtown Urban Renewal Districts at full buildout,particularly as it relates to the upgrades of existing facilities. This project is being undertaken because there are concerns that uncertainty around wastewater facility needs are negatively impacting development. Specifically,developers are being required to expand infrastructure on an inefficient piecemeal basis adding cost to projects while not necessarily improving the capacity of the entire system. To do this,a build out analysis will be performed to determine the amount of development that can be supported under current zoning. The amount of development possible measured in square footage for commercial development and number of dwelling units for residential development,will be used,in conjunction with the Wastewater Collection Facility Plan and any other applicable documents to determine future wastewater flows and from that,the City and HDR will derive facility sizing using their existing wastewater facility model. A detailed scope of services for the project is outlined below and a map showing the proposed study area is attached for reference. Scope of Work: Phase 1-Project Initiation This phase of the project will include project initiation and planning tasks,including scoping,contract preparation,and meetings with the City of Bozeman. All project management tasks,client meetings and sub- consultant coordination for tasks beyond project initiation will be allocated to the remaining project phases. Phase 2—Review of Existing Documents To complete the buildout analysis,it will be necessary to have a thorough understanding of applicable plans and regulatory documents. These include,but may not be limited to: • Wastewater Collection Facilities Plan Update-June 2015 • City of Bozeman Zoning Code • City of Bozeman Community Plan Additionally,interviews or the use of questionnaires with City of Bozeman staff may be required to fill any gaps in information. Sewer Capacity Analysis Scope of Work Page 2 Base maps including required information such as sewer sub-basins,parcels,and zoning boundaries will be created. It is intended that the maps be created with existing information obtained from the City of Bozeman. Phase 3—Buildout Scenario To appropriately estimate wastewater facility needs for the study area as it redevelops,it will be necessary to create a reasonable buildout estimate for the area. From this buildout scenario,wastewater flows will be estimated. The buildout scenario will be based on current zoning and assumptions on maximum potential redevelopment in order to generate a conservative estimate of wastewater flows. Specific tasks within this phase include: • Examination of existing conditions in the study area related to existing development,lot patterns and infrastructure. • Identification of development and re-development lots and parcels. • Creation of development assumptions for items that may impact development yield but are not specified in the zoning code. (For example,while structured parking may be allowed in the zoning code and would increase development yield,we would assume that it is unlikely to occur for economic reasons within the Midtown District.) • Based on City zoning,building setback,height,parking and open space requirements,a typical Floor Area Ratio (FAR) of development will be created. This FAR will be applied to previously identified development sites to derive a total amount of building square footage per site. • For sites with existing buildings slated for redevelopment,existing flows will be estimated based on the FAR of the existing structures. • Assumptions will be made regarding the use of the development,either commercial,residential,or mixed,in order to estimate wastewater flows. Phase 4—Allocation of Wastewater Flows to Parcels From the buildout scenario,the amount of wastewater flowing from each development parcel will be estimated based on the parcePs use. Specific tasks within this phase include: • Reconciliation of per acre wastewater flows from Wastewater Collection Facilities Plan with buildout scenario units (square foot or acres for commercial development,number of dwelling units for residential development). • Determine wastewater flows from parcels or groups of parcels as appropriate. Phase —Systems Impact Analysis Working with City Engineering staff,Sanderson Stewart will provide anticipated wastewater flows from each development parcel or group of parcels,which will then be modeled by the City of Bozeman and HDR. Specific tasks within this phase include: • Assign each development parcel to a wastewater main based on existing basins. • Aggregate flows from development parcels to specific wastewater mains. • Based on estimated flows,determine needed wastewater main sizes (by City of Bozeman and HDR). Sanderson Stewart will coordinate with HDR on the format of information to be provided for modeling. Phase 6—Summary Report A summary report will be prepared in memo format to document the analysis and identify future actions.The information collected during the project will include the following: • Study area boundary and rationale • Summary of existing conditions of the wastewater collection system within the study area • General build out assumptions and methodology Buildout scenarios for development parcels Sewer Capacity Analysis Scope of Work Page 2 Summary of system impacts • Targeted improvements and action items Fees and Billing Arrangements: Midtown District Proposed Fees Phase Fee 1.
