Council expressed support for the draft document and requested minor updates and additional information, which have been incorporated into the draft WIDIIS document. Staff requests Council’s review and adoption of the WIDIIS. Update Since the prior draft, the West Innovation District Integrated Implementation Strategy has been refined to provide greater clarity, alignment with adopted City plans, and improved usability as an implementation tool. Updates were made to the Sustainability and Resilience Evaluation Criterion to strengthen the strategy’s emphasis on reducing car dependence, expanding multimodal access, and improving connectivity in a manner consistent with the Envision Dublin MultiModal Thoroughfare Plan (pg. 37). Additional clarity was provided on the purpose of the character areas and select character area labels were updated to more accurately reflect current and planned uses, including renaming the Premier Athletic Complex as the Premier Athletic & Recreation Campus and the Business Park as Employment District (pg. 6). Minor clarifications were also made to improve readability, including added introductory language to the Priority Matrix distinguishing the meaning of its symbols (pg. 34). The implementation framework itself was also enhanced to better support project sequencing and decision-making. Additional context was added to each of the twelve implementation recommendations to clarify the intended land use outcomes enabled by each investment. The introduction to the recommendations was revised to more clearly describe how projects are organized based on development dependencies and how the Development Area summaries should Office of the City Manager 5555 Perimeter Drive • Dublin, OH 43017 Phone: 614.410.4400 Memo Memo re.

Finally, the Monitoring and Updating section was updated to document that the strategy reflects the best available planning, engineering, and market information as of April 2026, reinforcing transparency and setting appropriate expectations for future updates as conditions evolve (pg. 37). Summary The WIDIIS illustrates the vision for the West Innovation District (WID) as outlined in the Envision Dublin Community Plan. The innovation analysis, character areas, opportunity areas and development pods will help guide the implementation of the WIDIIS and assist the City with strategic investments and infrastructure phasing. The plan will be a tool, providing a basis for evaluating priorities for development in the WID. The detailed memo from the April 13, 2026 introduction is included for Council’s reference and provides significant background information and a detailed description of the draft WIDIIS.

Encompassing approximately 2,250 acres along the City’s western edge, the District includes the City’s most substantial opportunity for employment-generating land uses. As a key employment and innovation area within the City and the region, the WID is intended to support research, technology, and high- quality employment uses that complement surrounding neighborhoods and adjacent jurisdictions. City Council’s 2025 and 2026 goals to accelerate and catalyze economic development in the District underscored the need for a coordinated and strategic approach to infrastructure investment and implementation. The Strategy builds directly on the policy direction established through Envision Dublin and the adopted West Innovation District Special Area Plan. Those plans define the District’s boundaries, land use framework, development character, and supporting infrastructure principles. Rather than revisiting those policy decisions, this Strategy translates them into an actionable implementation framework that clarifies how and when infrastructure investments should occur, how development areas may be sequenced, and how public and private investment can be aligned around shared priorities. The Strategy provides a coordinated roadmap for guiding public infrastructure investments that support site readiness, orderly growth, and long-term economic development in the WID. It integrates previous and ongoing planning efforts related to transportation, utilities, economic development, housing, and parks and recreation into a unified decision-making framework. By aligning infrastructure planning with future land use expectations and development intensity, the Strategy helps prioritize investments that advance Council’s goals, reinforce the District’s intended role, and support consistent and coordinated actions across City departments, development partners, and neighboring jurisdictions. The WID's regional context is a critical consideration throughout this work. The District is influenced by surrounding jurisdictions, regional transportation networks, and broader economic trends. Infrastructure decisions within the District have implications beyond City boundaries, making thoughtful coordination and long range planning essential to achieving both local and regional objectives. This Strategy emphasizes collaboration to ensure infrastructure investments support shared outcomes over time. The Strategy was developed through a deliberate and transparent process that included technical analysis of transportation, utility, and site readiness conditions, coordination across City divisions, engagement with key partners and stakeholders, and direction from City Council. That direction helped shape priorities and ensure the Strategy reflects community values, adopted policy, and implementation expectations. The Strategy is intended to improve predictability in development review, optimize land and infrastructure planning, enhance connectivity, and improve utility capacity. These efforts support an authentic identity for the WID as Dublin's premier employment and innovation center. 1East of SportsOhio, looking southwest WID Geography WID WID+ Plain City R a i l Dublin FRANKLIN CO.MADISON CO.UNION CO.DELAWARE CO. Columbus N The WID is located along Dublin’s western edge and encompasses the City’s largest concentration of employment-oriented land. The district covers approximately 2,250 acres from Avery Road west into Madison County, and State Route 161 south to Rings Road. While outside the City’s corporate limits, an additional 4,841 acres is designated as the WID+, and extends into Union County and further into Madison County. The WID+ plays an important role in long-term infrastructure planning and regional coordination. Existing utility constraints limit near-term development in the WID+. Envision Dublin Future Land Use Map Economic Role of the WID The WID and WID+ geography contain 89% of Dublin’s Flex Innovation land and 100% of its Industrial land based on the Envision Dublin Future Land Use Map. This concentration of employment-oriented land uses positions the WID as Dublin’s primary opportunity to accommodate future job growth and innovation. In 2025, City Council established a goal to Accelerate Economic Development in the West Innovation District, recognizing that the district offers a unique opportunity to broaden the City's business portfolio and drive innovation and growth in the region. City Council reaffirmed this goal in 2026 to catalyze economic development in the WID.

As illustrated on the left side of the graphic, this work spans multiple domains including economic development, housing, transportation, parks, utilities, and special area planning, and reflects plans and initiatives developed from the late 2000s through more recent years. Studies and plans that have an arrow at the end indicate work that is ongoing. A key objective of this effort was to acknowledge that this policy landscape is dynamic and evolving, and to intentionally incorporate work that, while still underway, has become clearer and more actionable over time. This integration is not meant to stall progress, but rather to align it and feed it back into the City’s existing implementation mechanisms, including the capital improvements program, annual work programs and budgets, operational decisions, and private development actions. On the right side of the graphic, this structure translates integrated policy into coordinated action and measurable outcomes. All of this ultimately serves Dublin’s broader vision of being a global city of choice, where sustainability, resilience, and connectivity are foundational principles guiding both public investment and private development decisions. 3 Process The Strategy was developed through a structured process combining technical analysis, stakeholder engagement, and City Council direction at key milestones. The team reviewed adopted plans and current infrastructure initiatives, conducted site visits with City staff, and performed technical analysis across land use, transportation, utilities, housing, and economic development. Focused interviews with property owners, institutional partners, neighboring jurisdictions, and Council members ensured alignment on development expectations, market readiness, and policy direction. The Strategy was developed in active coordination with several concurrent City initiatives. These efforts informed each other and will directly advance or shape implementation. visits with City staff, and performed technical analysis across land use, transportation, utilities, housing, and economic development.

Concurrent Projects Premier Athletic and Recreation Campus Vision Framework Establishes a long-term vision and master plan framework for an athletic complex within the WID, integrating recreation, economic vitality, and open space connectivity. Passenger Rail Study Identifies the optimal location for a new passenger rail station and guides land use and development of surrounding City-owned land within the WID. Setback and Mounding Study Develops landscape, screening, and development standards for industrial and manufacturing uses in the WID, providing a foundation for zoning updates and design guidelines. Signature Trail Study Establishes a vision and implementation framework for an east-west trail corridor connecting parks, neighborhoods, and destinations across the City, terminating in the WID. Tuttle Crossing Boulevard Extension A planned westward extension of Tuttle Crossing Boulevard, including new roundabouts and multimodal improvements. The extension is a long-range priority for opening undeveloped land in the WID and improving regional connectivity. University Boulevard Phase 3 The next phase of University Boulevard extension, programmed in Dublin's 2026–2030 CIP, that will complete north-south connectivity through the WID. SR 161 Corridor Study SR 161/Post Road serves as the primary east-west corridor of the WID. This study will evaluate long-range roadway improvements critical to WID access and regional connectivity. ODOT Thoroughfare Plan Coordination Ongoing ODOT thoroughfare planning along the SR 161/Post Road corridor will shape long-range roadway improvements critical to WID access and regional connectivity. The City should actively coordinate with ODOT to ensure WID priorities are reflected in the thoroughfare plan. 4 The Framework translates the WID vision into clear and actionable guidance by moving from a broad economic strategy to coordinated investment at the parcel level. It is organized around four interconnected components that work together to support implementation of the plan. Innovation serves as the foundational driver, establishing the economic and innovation strategy that guides decisions within the district. The character areas describe the intended role and feel of different parts of the district, guiding how development should be arranged and how places relate to one another. The Infrastructure Opportunity Areas identify groups of similarly situated locations where infrastructure capacity and investment needs align, helping prioritize and coordinate public improvements. Development Areas then apply a focused lens at the parcel level, illustrating how individual sites can be activated through coordinated public and private investment. Together, these components create a cohesive framework that aligns policy, infrastructure, and development decisions to support implementation of the WID vision. FRAMEWORK Innovation The motivational force behind the economic development strategy for the district Character Areas The place-based organizational framework to be realized through development Infrastructure Opportunity Areas Broad identification of similarly situated infrastructure capacity areas Development Areas Focused lens identifying how individual parcels can be activated through coordinated investment 5South of 161 near the railroad, looking southeast Innovation Innovation districts are geographically concentrated employment centers designed to accelerate collaboration, knowledge exchange, and business growth in high value industries. Unlike conventional business parks, they create the conditions for sustained, high wage employment by supporting companies across the full arc of growth, from early discovery and research through scaled operations that are embedded in the regional economy. Dublin's Innovation Ecosystem Dublin has established strengths in advanced and innovation driven sectors, including logistics, transportation equipment manufacturing, computer and software industries, life sciences and medical equipment, and advanced and precision manufacturing. Between 2020 and 2025, Dublin based companies secured 30 Department of Defense SBIR awards and $26.9 million in federal research funding. For a city of Dublin’s size, this level of activity reflects a strong base of firms engaged in applied research, product development, and commercialization. The WID builds on this momentum by providing the space, infrastructure, and flexibility needed to support the next stage of growth. It is designed to accommodate uses and scales of activity that are not available in other parts of the City, offering a distinct environment for firms as they expand, evolve, and move toward larger scale production and market presence. Defining District Roles Within Dublin’s Innovation Portfolio As one of the City’s seven business districts, the WID provides the scale, infrastructure capacity, and flexibility needed to support later stage innovation activities that require larger sites, specialized facilities, and operational intensity. These include advanced manufacturing, production, logistics-related uses that cannot be accommodated in more urban or constrained settings. The West Innovation District Innovation Implementation Strategy establishes the framework for how this district contributes to the citywide innovation ecosystem. Through its implementation, the strategy will strengthen Dublin’s ability to retain and grow innovative companies by providing a critical link between earlier stage innovation and long term, scalable operations. Character Areas Approach to Character in the WID Cluster Innovation in Strategic Nodes. Establish distinct, character-based nodes that foster a density of opportunities for collaboration and the necessary spaces and infrastructure to realize innovation. Areas such as the Multimodal Hub, Innovation Campus, and PARC will be the core of the district’s innovation identity and drive activity and interest in the West Innovation District. Enable High-Quality, Flexible Growth. The remainder of the district will support opportunistic economic development. These areas will be flexible to respond to market needs but always aligned with Dublin’s high standards for design, sustainability, resilience, and connectivity. Monitor and Align Regional Growth. For areas outside the WID, proactively engage with regional partners to align external growth with the Innovation District’s mission and vision, ensuring that infrastructure, land use, and economic development reinforce shared goals. At more than 2,200 acres, the West Innovation District is significantly larger than a typical innovation district. This scale requires differentiation rather than uniformity. The strategy intentionally embraces that diversity by organizing the district around three complementary character approaches that explain how different areas support innovation at different stages and serve distinct roles within the broader district. Character areas such as the Employment District, Premier Athletic and Recreation Campus, Multimodal Hub, Health and Research Corridor, and Innovation Campus help distinguish the varied functions, development patterns, and levels of intensity across the West Innovation District. Together, these areas differentiate focused environments for research, collaboration, mobility, and institutional investment from larger employment and growth areas designed for flexibility and long term evolution. This mix creates a continuum of innovation environments where character, infrastructure, and development align to guide coordinated action while reinforcing a cohesive identity for the district as a whole. 6 EMPLOYMENT DISTRICT Infrastructure Opportunity Areas Significant infrastructure investments are necessary to realize the WID vision. This section summarizes the water, sewer, and transportation infrastructure needs in the WID in order to assist the City in identifying investment priorities and making requests for capital funding. Stormwater infrastructure was considered at a high level for the district but was not reviewed to the same degree as water and sanitary utilities since site readiness is not as dependent on stormwater. The City of Dublin’s Stormwater Design Manual is the governing policy document when considering stormwater design on individual sites. The overall infrastructure investments required across the WID and WID+ have been grouped into “Opportunity Areas” based upon development readiness. The ability to serve areas with water and sewer infrastructure is a primary driver, as it enables roadway construction and ultimately supports future development. Accordingly, the Opportunity Areas are numbered to reflect their level of development readiness from a water and sewer infrastructure perspective. Opportunity Area 1 represents land that is the most development-ready in the district, with water and sewer infrastructure readily available. The construction of major roadway corridors and multimodal hubs will improve site access and mobility. Opportunity Area 2 represents land that is in need for offsite sewer or water extensions, or both. The construction of roadways will also be required to provide site access in conjunction with utility infrastructure. Opportunity Area 3 represents land that requires the same infrastructure improvements as Opportunity Area 2, but also requires additional jurisdictional coordination due to its location outside of the Dublin Water and Sewer Service Area. Opportunity Areas 4 & 5 represent land that is outside of the WID boundary, in an area referred to as the WID+. The path to infrastructure has additional challenges compared to areas within the WID. A GIS Web Experience has also been created. This interactive tool is designed to support the City’s evaluation of potential utility extension scenarios, enabling interactive exploration of alternative build-out configurations at a planning level. The platform was specifically created to support the City in discussions with developers and capital planning decisions. The transportation assessments presented in this section build upon the foundation established in the Envision Dublin Multimodal Thoroughfare Plan. Several transportation planning and engineering studies within the WID are also underway concurrently. Refined corridor alignments from these ongoing efforts are incorporated throughout the exhibits, and references to the active studies are included where relevant. The utility assessments in this section are at a planning-level of detail. Final capacity constraints and detailed infrastructure sizing will depend on information from the Water Utility Master Plan (WUMP), the Sanitary Sewer Utility Master Plan (SSUMP), and subsequent detailed engineering phases. 7 In Opportunity Area 1, water and sewer infrastructure is readily available and therefore represents the most development-ready areas in the district. Sewer & Water Infrastructure This area is located within the Dublin Water and Sewer Service Area and within the existing Post pressure district, as evaluated in the Envision Dublin Water Infrastructure Report. Parcels are adjacent to existing water mains and sewer mains within their respective sanitary sewersheds (South Fork Indian Run, Cosgray, and Cramer North). While existing water lines and sewers are in close proximity to serve the larger opportunity area, some utility main extensions will be required within the boundaries of Development Areas, to be more defined in coordination with future planning of site development and related infrastructure. On-site utility extension requirements will vary based on individual site development plans and will necessitate detailed engineering and design by developers as part of the development review process. Note, based on projected full buildout of future land uses identified in Envision Dublin, capacity of the existing trunk sewer serving the South Fork Indian Run tributary area is expected to be exceeded, necessitating future downstream capacity improvements. Development triggers and recommendations for these anticipated capacity upgrades will be addressed in the forthcoming Sanitary Sewer Utility Master Plan. Modernize Cosgray Road Cosgray Road reflects a rural 19th century county road typology, which falls short of modern transportation, safety, and multimodal infrastructure standards. Improving Cosgray Road to a modern street section is important to support development in Opportunity Area 1. The City’s Multimodal Thoroughfare Plan calls for a 4-lane divided section on Cosgray Road. The future geometry, typical sections, and intersection control are being studied in coordination with both Premier Athletics & Recreation Campus (PARC) planning and study of the larger Cosgray Road corridor from SR-161 to Rings Road. Construct University Boulevard Phase 1 and Phase 2 have been built, and a study to determine the alignment for Phase 3 was conducted and the alignment is included in the strategy. Constructing Phase 3, which is identified as a Commuter Boulevard, will provide access for adjacent development and mitigate stress on the existing and future street network. Construct New Street 4 to 500 +/- feet east of Railroad The New Street 4 alignment was refined as a part of this effort in coordination with PARC planning. However, the precise alignment of New Street 4 and location at which it will cross the railroad will be determined through a full future alternatives evaluation and public engagement process. The construction of this street, identified as a Commuter Boulevard, will help to shift east-west traffic away from residential areas along Shier Rings Road and should be constructed to a point approximately 500 feet east of the railroad at the limit of future railroad bridge approach embankment. Additionally, the construction of a new US- 33 overpass as a part of the roadway will shift local traffic away from interchange areas at Post Road and Avery-Muirfield Dr. Opportunity Area 1 Construct Additional Multimodal Improvements The Signature Trail runs through this area and is assumed to need a right-of-way (ROW) of approximately 30 feet per the Signature Trail Plan dated 12/8/2025. Additionally, there are two planned mobility hubs identified in Envision Dublin in this area. Mobility investments will support the vision for innovation and connectivity in this district. Additional planned Neighborhood Boulevard streets will also need constructed on a project-by-project basis. 8 In Opportunity Area 2, significant offsite sewer and/or water extensions will be required to support future development. Opportunity Area 3 will require similar offsite utility extensions; however, additional jurisdictional coordination will be necessary because this area lies outside the Dublin Water and Sewer Service Area. Opportunity Area 2 was split into Areas 2A and 2B to reflect the sewershed boundaries for Cosgray and Hayden Run. The construction of roadways and multimodal infrastructure will also be required in these areas to establish adequate site access in conjunction with utilities. Opportunity Areas 2A, 2B & 3 Sewershed Boundaries 9 Construct Sewer Mains (Areas 2A & 3) Areas 2A and 3 will require offsite sewer main extensions within the Cosgray sewershed, the first originating from the existing sewer main at Larne Dr. and Cosgray Road, the other originating south of the Eiterman Road and University Boulevard roundabout. Implementing the extension from Larne and Cosgray will require modification to the existing Cosgray sewershed tributary area and approval from the City of Columbus. Based on development densities outlined in Envision Dublin, this sewershed has been determined to have sufficient capacity to handle the anticipated flows. Area 3 will require additional coordination because it lies outside the Dublin Water and Sewer Service Area. Extending service to Area 3 will require engagement with the Ohio Environmental Protection Agency (OEPA) to modify the 208 Boundary for sewer service, along with updates to the utility service agreements with the City of Columbus. Area 3 also falls within the sewer jurisdiction of Madison County and/or the Mid-Ohio Water and Sewer District, requiring further coordination with these entities. The required offsite sewer extensions and the associated delineated service areas by parcel for Areas 2A and 3 in the Cosgray Sewershed are shown on the map to the right.

(approx. 2 miles of pipe). Based on the development densities outlined in Envision Dublin, the Hayden Run sewershed has sufficient capacity to accommodate the expected flows associated with future development. The required offsite sewer extensions and the corresponding delineated service areas by parcel for Area 2B within the Hayden Run Sewershed are shown on the map to the right. Please note, service accessibility is likely to change as parcels are subdivided and evaluated on a case-by-case basis. The proposed offsite sewer extensions are shown as gravity mains and are preliminary in nature, based on a remote analysis of existing elevations. A more detailed engineering analysis will be required to confirm feasibility and determine whether pump stations and force mains may be necessary in certain locations.

Area 3 lies outside the Dublin Water and Sewer Service Area, therefore a modification to the utility service agreements with the City of Columbus will be necessary. Additionally, Area 3 is outside of the existing pressure district (Post) evaluated by the Envision Dublin Water Infrastructure Report. The northern water extension would provide service to portions of Area 2A and to Area 3 and include proposed extensions from both the Darree Fields water tank and SR 161 and Crosby Court. The loop consists of segments W1A, W1B, W2A, W2B, W2C, and W2D. Segments W2B and W2C are currently shown to follow the alignment of New Street 1. However, portions of this corridor are outside the Dublin Water and Sewer Service Area. Either an alternative alignment (water alignments only or water and street alignments) or detailed coordination with the City of Columbus would be required to implement this portion of the northern water extension.

The loop including proposed segments W1A, W1B, W3A, W3B, W3C, W3D, and W3E. Please note, this concept assumes outer loop segments will likely require 12” diameter pipes based on projected future land uses and population growth. An additional connection, Segment W4A, is also recommended. This segment consists of a 16-inch diameter water main along Shier Rings Road between Eiterman Road and Cosgray Road. W4A is intended to complete the inner water loop, creating system redundancy and reducing strain on both the existing and expanded water network as water demand increases with full build-out of the WID. At this stage, pipe size and other infrastructure improvements are considered highly variable, as final requirements will depend on actual land use, development intensity, and timing of build-out. Additionally, service accessibility may shift as parcels are subdivided and evaluated on a case-by-case basis.

However, the precise alignment of New Street 4 and location at which it will cross the railroad will be determined through a future alternatives evaluation and public engagement process in coordination with future PARC and Passenger Rail Station planning. A bridge over the railroad and the final construction of New Street 4 will provide an east- west route for local traffic and an alternative to SR-161 or Rings Road. The overpass will support removal of the at-grade crossing of Houchard Road across CSX. This portion of the street, identified as a Commuter Boulevard, is recommended to have utility mains extended along it at the time of construction due to the coordination that will be required with the property owners of the developed properties in this area. Additionally, since the necessary utility main extensions will require a modification to the existing Cosgray sewershed tributary area and approval from the City of Columbus, this portion of the street being built may be contingent on that approval to ensure utility availability. Construct New Street 1 from Tuttle Crossing Boulevard to SR-161 The construction of this street as a Connector Boulevard will provide a modern roadway alternative to Houchard Road that is aligned completely west of the railroad. It will also form a street grid with other elements of the Multimodal Thoroughfare Plan that promotes flexible circulation in the WID and WID+ and connects with regional routes. In addition to network connectivity, this roadway will also provide access to multiple developable parcels in the western portions of WID. Improve SR-161 ODOT recently commissioned a study of SR-161 (MAD-UNI-FRA-161 Study) to evaluate the impacts of anticipated development on and around the SR-161 corridor between US-42 and the US-33 interchange. That study recommended Phase 1 build improvements to SR-161 adjacent to Opportunity Areas 2 and 3. Those improvements include expansion of SR-161 to a 4-lane divided roadway west of Cosgray Road and future railroad-grade separation with CSX tracks located west of Houchard Road. Those Phase 1 improvements should be planned in coordination with ODOT and other regional partners. Construct Tuttle Crossing Boulevard from Wilcox Road to New Street 1 The Tuttle Crossing Boulevard alignment, west of Cosgray Road, was refined as a part of this effort, yet, a more detailed engineering study is needed and is advancing on a parallel path. The construction of this roadway as a Connector Boulevard will benefit the WID and the Southwest Area and provide a 2nd grade-separated rail crossing. The future roadway will mitigate potential increases in traffic on Rings Road and Churchman Road and facilitate access to and from I-270. This investment is dependent on other phases of the roadway being built in order for it to provide the regional transportation connections between SR- 161 to I-270. It is also dependent upon obtaining water and sewer service in this area to ensure that all parcels in the WID are accessible for development. West of New Street 1, additional segments of Tuttle Crossing Boulevard may be important to unlock areas for development. This is alignment-dependent and subject to further review as part of a separate Tuttle Crossing Boulevard Alignment Study under which, alignment alternatives are being developed and analyzed. Construct Additional Multimodal Improvements There is one planned mobility hub identified in Envision Dublin in this area which is the passenger rail site. The Signature Trail runs through this area and is assumed to need a right-of-way (ROW) of approximately 30 feet to provide a low stress corridor for walkers and rollers to access the passenger rail site. Additional planned neighborhood boulevard roadways will also need constructed on a project-by-project basis. Transportation Investments 14 In Opportunity Areas 4 and 5, access to utility infrastructure presents several challenges. Roadway construction may be closely tied to the availability and alignment of utility services, and in some cases, utilities may need to be extended prior to or concurrently with roadway improvements to unlock development potential. The following summarizes the infrastructure investments needed in this area. Sewer Infrastructure For these areas, extending sanitary sewer service will require a regional approach. Due to natural topographic drainage patterns that direct flow to the west, accommodating sewer needs will likely require a pump station and force main infrastructure. Opportunity Areas 4 and 5 are not included within the tributary area of any existing Dublin or Columbus sanitary sewer system, and existing downstream sewers lack the capacity to accommodate projected flows based on the planned development densities identified in Envision Dublin. Portions of these areas also fall outside the Dublin Water and Sewer Service Area, necessitating updates to the utility service agreements with the City of Columbus. Because of the Ohio EPA 208 Facility Planning Area designations, identifying all of Areas 4 and 5 to be under other management agencies, sewer service development may also require collaboration with additional management agencies, including Madison County, Mid-Ohio Water and Sewer District, and/or Union County and Marysville. In certain locations, existing utilities owned by Marysville and Madison County, as well as planned Mid-Ohio Water and Sewer District infrastructure, will also need to be considered as part of a coordinated regional solution. Extension of existing Dublin sewer infrastructure (assumed by pump stations and force mains) into Areas 4 and 5 will require coordination and acceptance by the designated management agency for the areas to be served. Water Infrastructure The extension of existing water mains will be required to serve these areas. However, portions of Opportunity Areas 4 and 5 already contain existing or planned water infrastructure owned by other service providers (Marysville and Madison County). Extending water service from Dublin and Columbus into areas outside the Dublin Water and Sewer Service Area would require modifications to the existing utility service agreements with the City of Columbus. In addition, these areas fall outside the existing Post pressure district evaluated in the Envision Dublin Water Infrastructure Report, necessitating further coordination to determine appropriate pressure zone and service configurations. Current utility service agreements with Columbus prohibit the extension of water and sewer services from other providers into areas located within Dublin’s corporation limits. If Dublin plans to include portions of Opportunity Area 5, water and sewer service from another provider or providers may be worth consideration. A legal review is recommended to evaluate the authority, constraints, and procedural requirements associated with providing utility service into the WID+, either by extension of Dublin and Columbus infrastructure, or by utilizing other utility service providers such as Marysville or Mid-Ohio Water and Sewer District. Opportunity Areas 4 & 5 Water and Sewer Investments 15 Construct Tuttle Crossing Boulevard Extension to SR-161 The Tuttle Crossing Boulevard alignment was refined as a part of this effort, yet, additional refinement is being advanced under a separate study of alternative alignments and associated impacts. The construction of this roadway as a connector boulevard will facilitate development south of SR-161 in Opportunity Area 4 and will provide a regional traffic benefit by connecting SR-161 to I-270. ODOT recently commissioned a study of SR- 161 (MAD-UNI-FRA-161 Study) to evaluate the impacts of anticipated development on and around the SR-161 corridor between US-42 and the US-33 interchange. This study found that, under full build traffic projections for the year 2050, additional local transportation connections between Plain City and Dublin, like Tuttle Crossing Boulevard, will be needed to improve regional connectivity and limit congestion on SR-161. Improve SR-161 The MAD-UNI-FRA-161 Study described above recommended Phase 1 build improvements to SR-161 which include a 4-lane divided roadway from Warner Road to Cosgray Road and future railroad-grade separation with CSX tracks located west of Houchard Road. Those Phase 1 improvements should be planned in coordination with ODOT and other regional partners. Construct Additional Streets North of SR-161 Other planned roadways north of SR-161 were not studied as part of this report and should be analyzed as part of a future multi-agency thoroughfare planning study led by ODOT and MORPC which will build on the conclusions of the MAD-UNI-FRA-161 Study to develop recommendations for the future street network in this area. The eventual construction of this street network would facilitate development west of Industrial Parkway and provide alternative routes to SR-161, Industrial Parkway, and US-33. Transportation Investments 16 Area A —Neighborhood Commercial Area A is the eastern gateway to the WID, intended to provide neighborhood-serving commercial uses that support the surrounding workforce and residential community. It is among the most development-ready areas in the district, with existing water and sewer service in place and no offsite utility extensions required. The area is characterized by small parcels and fragmented ownership, which may require land assembly and coordination to complete the proposed New Connector Boulevard. Capital investment is otherwise limited to internal utility extensions and site access improvements. Area B — Corporate Office and Institutional Area Area B is positioned along the University Boulevard and Shier Rings Road corridors to accommodate corporate office and institutional uses at a scale consistent with the district's innovation identity. Water and sewer infrastructure is already in place, and no offsite utility extensions are required. Investment will focus on internal extensions and site access improvements advanced through development review. Area B access will benefit directly from University Boulevard Phase 3. Area C — University Boulevard Phase 3 Area Area C is a significant near-term development opportunity positioned along the University Boulevard Phase 3 corridor, intended for a broad mix of uses including mixed-use neighborhood development, residential, and flex and innovation space closer to University Boulevard. Portions of the area are already served by existing infrastructure, but full buildout requires University Boulevard Phase 3 to be constructed first, as it serves as both the primary access route and the utility corridor for this area. Cosgray Road modernization and Cosgray sewer extensions E1 and E2 are also prerequisites, both of which are dependent on Phase 3 being in place. Area D — Suburban Office Center Area D is a development-ready suburban office location with strong visibility and access along the US-33 corridor. Water and sewer infrastructure is in place, and no offsite utility extensions are required. Investment will be limited to internal extensions and access improvements. Area D is well-positioned for near-term private development with minimal public infrastructure commitment required. Area E — Mixed-Use Center Area Area E is envisioned as a higher-intensity mixed-use center anchored by the Ohio University Dublin campus, intended to support innovation, education, and complementary commercial and residential uses. Its activation is closely tied to infrastructure investments being made for the adjacent PARC site, meaning that progress on Area G directly advances Area E. Key prerequisites include Cosgray Road modernization, University Boulevard Phase 3, New Street 4, and coordinated Cosgray sewer main extensions. As PARC-enabling investments advance, Area E should be treated as a concurrent activation opportunity. Development Areas To support the implementation of projects in the WID, Development Areas were identified based on existing and future land uses, as well as the anticipated likelihood of concurrent development activity. Grouping areas with similar infrastructure needs may provide opportunities for coordinated investments that unlock multiple Development Areas simultaneously. 17 Area F — Established Flex Employment Area Area F is the most established employment area in the WID, with a functioning development pattern that demonstrates the district's potential and provides a foundation for adjacent growth. Water and sewer service is fully in place, and no offsite utility prerequisites are required. Area G — PARC Area G is the district's highest-priority activation site, designated for the Premier Athletic and Recreation Campus. The City has identified PARC as the catalytic anchor investment for the WID, and its delivery is expected to generate the activity, identity, and market confidence needed to accelerate private development across adjacent areas. Active planning for the PARC is underway. Achieving service readiness requires a coordinated sequence of investments including Cosgray sewer main extensions from Larne Drive and Cosgray Road, University Boulevard Phase 3, New Street 4, and Cosgray Road modernization. These investments should be treated as a unified delivery effort with PARC activation as the shared outcome. Area H — Future Flex Innovation Area (East) Area H is designated for future flex and innovation employment uses and is positioned to benefit directly from infrastructure investments serving the adjacent PARC site and Area E. It is a near-to-mid-term development opportunity, with buildout contingent on New Street 4, Cosgray sewer main extensions, Cosgray Road modernization. As PARC-enabling investments are delivered, Area H should be evaluated for accelerated marketing to capture overflow demand from adjacent development activity. Area I — Multimodal Hub / Passenger Rail Site Area I is one of the most strategically significant sites in the West Innovation District, designated as the location of a planned passenger rail station. Its development has the potential to catalyze transit-oriented investment across the western portions of the district and establish Dublin's presence on a regional passenger rail network. It is also the most infrastructure-complex area within the WID. Portions of the site lie outside the Dublin Water and Sewer Service Area, requiring OEPA coordination to modify the 208 Boundary and updated utility service agreements with Columbus. This Phase 2 priority development area requires significant infrastructure investment, including the construction of New Street 4 from approximately 500 feet east of the CSX railroad, extending over the rail to New Street 1. This roadway will also accommodate water lines W1A and W1B. It is important to note that this is a long-term priority and is not intended for near-term construction. Additional prerequisites include Cosgray sewer main extensions, New Street 1, and the Northern Water Extension, and segments W2A through W2D along the New Street 1 corridor. Interagency coordination actions should be initiated early, as they carry the longest lead times of any investment in the district. Area J — Houchard Road South Area J represents the largest undeveloped land area in the WID and is designated for flex innovation and employment uses with long-term potential for significant job creation. It is the final phase of WID buildout, requiring the most extensive new infrastructure investment in the district. Development readiness depends on Hayden Run sewer main extensions, the Southern Water Extension, and Tuttle Crossing Boulevard all advancing together as a coordinated package. These investments are co-dependent and must be programmed on a unified schedule. While Area J is a longer-horizon opportunity, early programming of utility extensions in the CIP is essential to ensure the dependency sequence is properly established and that the area can be activated when market demand reaches the western portions of the district. 18 The following pages detail the specific infrastructure needs for each Development Area, along with the planning-level estimates of construction cost. These details are intended to support decision-making and help the City prioritize investments that align with development potential in the WID. The information for each Development Area on the following pages includes several assumptions and caveats, outlined below. Water and Sewer Main Extensions Simplified planning cost per linear foot based on inclusion of the following items and assumptions: • All water main extensions are 12” in diameter, with the exception of the 16” diameter W4A, ductile iron at a depth of 0 to 8 feet, with pipe fittings, bedding, and backfill included. • Fire hydrants installed, spaced 300’ apart. • All sewer main extensions are 15” or 10” diameter, as noted, PVC, with pipe fittings, bedding, and backfill included. • Sewer manholes installed, spaced 300’ apart. • Connection(s) to existing main or previous extension. • Pavement repair/replacement: Limited to no replacement assumed for water main extensions aligned with proposed roadways, moderate pavement replacement assumed for water main extensions aligned with existing roadways. • Additional 30% allotted for miscellaneous and subsidiary construction items such as Maintenance of Traffic, Sediment and Erosion Control, Staking, etc. • Additional 15% planning level contingency added to cover unknown items discovered during survey, design, or construction. • The costs do not include survey, design, right-of-way acquisition, reimbursable utility relocations, or construction management/inspection • Costs are in today’s dollars and do not include inflation. The upsizing of upstream water mains, and other system improvements are likely warranted upon full implementation of Envision Dublin future land use, based on the increase in projected demands. The downstream system improvements in the South Fork Indian Run Sewershed are warranted upon full implementation of Envision Dublin future land use, based on the increase in projected wastewater flows. However, expansion of the water and sewer systems into the WID for one development area alone does not trigger these downstream improvements. More information on overall recommended system improvements as a function of projected increased water demands and sewer flows can be found in the WUMP and the SSUMP. Acreages Developable Area quantities are based on County Auditor acreages when applicable and ArcGIS measurements where parcels are bisected by proposed roadways. Potential setbacks, easements, right-of-way, and other preservation area requirements within these parcels are included in these quantities, as they vary based on specific site characteristics established in the development process such as establishment of land use, zoning, overlays, site configuration, and other factors. Transportation Infrastructure The construction costs of street improvements shown on the Development Area graphics are based on per-linear-foot costs of similar projects including common components such as pavement, curbs, walks, paths, street lighting, street trees, signage, pavement markings, storm sewers, stormwater management, and incidentals. Those per-foot estimates were adjusted to include other construction costs such as bridges, culverts, traffic signals, and/or roundabouts where appropriate and minor water main and sanitary sewer extensions not otherwise covered under specific utility infrastructure investments. See the “Notes” column in the “Infrastructure Needs” tables for information about the assumptions for each particular segment of street. The costs do not include survey, design, right-of-way acquisition, reimbursable utility relocations, or construction management/inspection. Costs are in today’s dollars and do not include inflation. Stormwater The Development Area exhibits show known storm sewers, streams, floodplains, and stormwater basins. All development in the WID will need to manage stormwater quantity and quality according to the Dublin Stormwater Design Manual. Street improvements will also need to follow the Stormwater Design Manual’s requirements for Right-of-Way projects. Costs for right-of-way stormwater management are included in the construction costs listed for streets on the Development Area exhibits. The Development Area exhibits show existing drainage information and identify potential stormwater outlet locations for public and private infrastructure. These outlets have been identified based on GIS-level information and record plans/reports. Evaluating the suitability of these outlet locations is beyond the scope this study; site-specific engineering studies will be required to verify the location, condition, and suitability of these stormwater outlets. It is notable that the watershed divide between the Scioto River and Big Darby Creek is generally located just west of the Franklin–Madison County line, with areas west of the county line draining to Big Darby Creek. The Ohio Environmental Protection Agency (OEPA), through General Permit OHC000006, establishes specific requirements for construction activities within the Big Darby Creek watershed, as detailed in Appendix A of the permit. Preliminary stormwater analysis indicates that portions of Development Area I may be located within the Big Darby Creek watershed and would therefore be subject to these additional requirements. The remaining Development Areas appear to lie within the Scioto River watershed.

This section establishes a sequenced approach for consistently applying the strategy across infrastructure investment, development review, and ongoing planning and funding decisions. Implementation occurs through a set of coordinated processes that shape how the district develops. The City's Capital Improvement Plan (CIP) sequences infrastructure investments based on the strategy’s phasing framework, prioritizing projects that unlock development-ready areas and establish critical transportation and utility networks. Development review applies the strategy at the site level, using it to evaluate rezonings, entitlements, and infrastructure agreements for consistency with planned land use, connectivity, and service capacity. Annual work programs and budgets translate these priorities into near-term actions, advancing design, engineering, and project delivery in alignment with the strategy. Economic incentives reinforce this approach by directing public resources toward projects that support innovation, employment, and catalytic development. Supporting tools extend the strategy’s application across decisions and over time. The interactive mapping platform provides a current view of infrastructure conditions and development readiness, informing project timing and coordination. The strategy also serves as a consistent reference for communicating investment priorities and development expectations. Together, these processes create a cohesive implementation framework that aligns capital planning, development activity, and policy decisions. By embedding the strategy within these mechanisms, the City can coordinate investment, guide growth, and maintain a clear and sequenced path toward full buildout of the West Innovation District. IMPLEMENTATION 32West of Avery & Shier Rings intersection, looking west The WID's build-out follows a deliberate east-to-west logic driven by infrastructure readiness. Opportunity Area 1 is best positioned for near-term activation, as water and sewer service is already accessible across much of the area. Realizing that potential, however, requires targeted investments in road access, utility extensions, and annexation for select parcels. The City has identified the PARC (Development Area G) as its highest-priority activation site. Sewer main extensions through the Cosgray sewershed, University Boulevard Phase 3, New Street 4, and Cosgray Road improvements are the foundational investments required to bring it online. These same projects create immediate spillover benefits, unlocking the Ohio University mixed-use center (Development Area E) and adjacent areas C and H simultaneously. Serving the multi-modal hub and passenger rail site (Development Area I) is a longer- lead effort. Portions of Area I fall outside Dublin's current service area, requiring OEPA coordination to modify the 208 Boundary and updated agreements with Columbus. New Street 1 and the northern water extension are additional prerequisites. In the south, Hayden Run sewershed extensions, the southern water extension, and Tuttle Crossing Boulevard must advance together to bring Development Area J to readiness. The tables below outline the dependency structure governing water and sewer extension sequencing. Independent extensions are the earliest actionable projects; all others must follow their predecessors to operational status before advancing.

Timing will respond to market demand, funding availability, and private development interest. While multiple projects may advance concurrently, the priorities matrix identifies the sequence in which infrastructure investments should occur.

Development sequencing in the WID follows an east-to- west logic driven by infrastructure readiness. The existing road network supports near-term investment in Areas A through E. Areas G and H depend on Cosgray Road improvements and University Boulevard build-out, both are currently in planning or early design. Areas I and J require entirely new street networks, large-scale annexation, and in some cases federal coordination, placing them in a longer planning horizon. 2. The PARC and University Boulevard are the district's highest-leverage investments. Their delivery unlocks access, utility service, and development potential across multiple adjacent areas simultaneously. Delay to either has compounding effects on the broader build-out timeline that no other single investment can offset. 3. Road access is the threshold condition for development. No parcel can be marketed, entitled, or constructed without a street connection. Recommendations that deliver the first road into an area take precedence over all other investments in that area. 4. Utility extensions must be timed to serve the first developable acreage. Water and sewer infrastructure should be designed concurrently with roadway construction to avoid redundant mobilization. Utility modeling should be tracked and updated wherever development intensity is proposed to exceed the assumptions in Envision Dublin. 5. Utility service in some areas can be provided following annexation into the City. When annexation enables the City to extend infrastructure or recover public investment, it should be treated as a critical dependency and be pursued prior to the infrastructure work itself. Assumptions 34 Implementation Recommendations The recommendations provide project-level implementation guidance for the twelve investments identified in the Priorities Matrix. Projects are organized to reflect the dependency structure established in the Development Area analysis. Reference the Development Area one-pagers and Infrastructure Sequencing for additional detail when considering each investment opportunity. 1. Prioritize Cosgray Sewer Extension B1. As the foundational trunk main serving Development Areas C and G, B1 unlocks sewer access to approximately 90 acres of Flex Innovation, Mixed-Use Neighborhood, and Park/Open Space and enables six downstream extensions that collectively serve the majority of Opportunity Areas 1, 2A, and 3. • Initiate formal coordination with the City of Columbus to modify the Cosgray sewershed tributary area boundary. This is a long-lead regulatory action that should begin independent of design progress. • Advance preliminary engineering to confirm 15" PVC gravity main alignment and grade within the Cosgray Road ROW. • Schedule Cosgray sewer extension B1 construction concurrently with New Street 4 and Cosgray Road Modernization to consolidate ROW disturbance and reduce total mobilization cost. • Establish a Cosgray sewer extension B1 delivery milestone aligned with the PARC construction timeline. 2. Advance University Boulevard Phase 3 to ROW acquisition and construction. Phase 3 provides primary access for Development Areas B, C, and D — designated for Suburban Office, Neighborhood Office, and Flex Innovation — and is a direct predecessor to Cosgray sewer extensions E1 and E2. Area C will remain only partially served until Phase 3 is complete, making timely progression through Detailed Design a near-term priority. • Confirm phasing and alignment with PARC planning as Detailed Design progresses. • Incorporate 12" water main and localized sanitary sewer extensions into the Phase 3 ROW at time of construction to avoid future pavement disturbance. • Engage adjacent property owners in Development Areas C and G during preliminary design to align site access configurations with the final cross-section. 3. Advance Cosgray Road modernization into a widening alternatives study. As the primary north-south spine of the WID, Cosgray Road is a shared prerequisite for Development Areas C, E, G, and H — designated for Flex Innovation, Mixed-Use Center, and Park/Open Space — and a common corridor for sewer and water utility extensions. Depending on the findings of the alternatives study, the project will move into either preliminary engineering or detailed design. • Use the alternatives study to evaluate potential segment phasing from SR-161 to Rings Road and confirm phasing with PARC planning. • Design roundabouts at Fishel Drive South/Heritage Road, Shier Rings Road, the PARC entrance, and Churchman Road concurrently with each roadway phase to avoid redesign costs. • Include the box culvert replacement at Indian Run within the northern segment design scope. • Confirm final geometry, typical sections, and intersection control through the active corridor study before committing to construction documents. • Coordinate landscape buffer and mounding design along Cosgray Road with the residential adjacency standards established through the WID rezoning process. 4. Construct New Street 4 from Cosgray Road to University Boulevard. This segment establishes the primary east-west collector within Opportunity Area 1, unlocking Flex Innovation and Park/Open Space parcels that currently have no viable street access, and will carry Cosgray sewer extensions B2 and D1 after the completion of extension B1. Columbus sewershed tributary area modification approval is a prerequisite for permitting Cosgray sewer extension B2 and should be initiated concurrently with preliminary design. • Finalize street alignment in coordination with PARC planning. • Incorporate Cosgray sewer extensions B2 and D1 into the construction contract as embedded utility scope. • Include a 12" water main extension and a roundabout at the University Boulevard intersection within the project scope. • Initiate Columbus sewershed tributary area modification approval concurrently with preliminary design. 5. Deliver the PARC infrastructure package as a coordinated effort. Cosgray sewer extensions B1 and B2, Cosgray Road Modernization, Houchard Road reconstruction, and New Street 4 between Cosgray Road and the CSX rail line must be sequenced and delivered together to activate the district's highest-priority catalytic site and generate the market signal needed to accelerate private investment in adjacent Flex Innovation and Mixed-Use areas. Establishment of a formal multi-project delivery schedule that treats PARC activation as the shared outcome across all contributing capital projects should be pursued. • Establish delivery milestones for Cosgray sewer extensions B1 and B2 aligned with PARC site construction documents and coordinated with New Street 4 extension. • Advance Houchard Road reconstruction from SR-161 to the northern limit of Development Area G to establish primary vehicular access. 35 6. Construct Cosgray Sewer Extension A1. A1 is independent of all other Cosgray extensions and can advance immediately, enabling Flex Innovation and Industrial parcels in Development Area H, and making it an early opportunity to demonstrate infrastructure progress in the district. • Advance Cosgray sewer extension A1 within the Cosgray Road ROW concurrently with other Cosgray corridor work to consolidate mobilization. • Complete a Job Ready assessment for newly served parcels upon Cosgray sewer extension A1 completion to activate annexation incentives consistent with the Envision Dublin implementation framework. 7. Construct the New Connector Boulevard from University Boulevard to Avery Road. This segment completes the street network serving Development Area A's 35 acres of Suburban Commercial and Suburban Office, establishes direct east-west access, and relieves interchange pressure at US-33 and Avery Road. • Include building and site demolition within the roadway footprint and removal of Old Avery Road within the base construction scope. • Include widening of Avery Road to provide a dedicated northbound left turn lane and dedicated southbound right turn lane. • Incorporate signal replacement at the Avery Road intersection into the project design scope. 8. Acquire ROW for the Signature Trail. The trail corridor provides the primary low- stress multi-modal connection between Development Areas D and I, including access to the planned passenger rail site, and doubles as the proposed ROW for Cosgray sewer extension B4. • Acquire a minimum 30-foot ROW corridor consistent with the Signature Trail Study. • Coordinate trail alignment with the PARC, along with adjacent roadway and utility projects to consolidate ROW acquisition and reduce total construction cost. 9. Begin ROW planning for the New Street 4 extension from University Boulevard to Hospital Drive. The US-33 bridge carries design, environmental review, ODOT coordination, and ROW acquisition timelines that require early action to avoid constraining future development. • Engage ODOT to establish bridge design standards, environmental review requirements, and a formal partnership framework. • Establish bridge finish quality and design standards consistent with the planned Shier Rings-Metro Connector and Emerald Connector bridges. • Begin property owner engagement along the alignment concurrent with ODOT coordination. • Coordinate bridge programming with COTA and regional transit planning to preserve the option for a future transit stop at Hospital Drive. 10. Construct New Street 1 from SR-161 to New Street 4, with Water Extensions W2B and W2C embedded. New Street 1 provides a fully grade-separated north- south alternative to Houchard Road, opens Industrial, Flex Innovation, and Mixed-Use Neighborhood parcels in Development Area I to utility service and development, and extends the WID street grid west as a critical access and utility corridor. • Advance preliminary design in coordination with the Tuttle Crossing Boulevard study. • Incorporate water main segments W2B and W2C into the construction contract, confirming alignment with Columbus service area coordination requirements. • Scope and schedule the southern segment from Rings Road/Tuttle Crossing Boulevard to New Street 4 as a subsequent dependent investment. 11. Construct Cosgray Sewer Extensions B2, B3, and B4 in sequence. These extensions advance the Cosgray trunk main progressively westward through approximately 93 additional acres of Flex Innovation and Industrial land across Development Areas C, G, H, and toward I, with each extension dependent on its predecessor. • Incorporate Cosgray sewer extension B2 into the New Street 4 construction contract to share ROW and avoid future pavement disturbance. • Advance Cosgray sewer extension B3 following Cosgray sewer extension B2 operational status; advance Cosgray sewer extension B4 following Cosgray sewer extension B3 operational status. • Complete a Job Ready assessment for newly served parcels upon Cosgray sewer extension B2 completion to activate annexation incentives consistent with the Envision Dublin implementation framework. • Coordinate Cosgray sewer extension B4 alignment with the Signature Trail ROW to consolidate corridor acquisition. 12. Construct Hayden Run Sewer Extensions with Southern Water Extension and Tuttle Crossing Boulevard as a coordinated Area J package. These investments are co-dependent and must be advanced together to unlock Area J's 646 acres of Industrial and Flex Innovation land, the district's largest Development Area and its longest-horizon employment opportunity. • Advance the Sanitary Sewer Utility Master Plan to confirm Hayden Run sewershed downstream capacity and establish development-trigger thresholds before committing to design. • Construct extensions in the required sequence: Hayden Run sewer extension A1 first, then A2; Hayden Run sewer extension C1 may advance concurrently with Hayden Run sewer extension A2 as it requires only A1; Hayden Run sewer extension A3 and B1 follow Hayden Run sewer extension A2. • Schedule the Southern Water Extension and Tuttle Crossing Boulevard concurrently with sewer extension design to deliver all investments on a coordinated schedule. 36 Capital and Operating Budget Work Sessions CIP and Operating Budget Adoption Project Evaluation Evaluation Criteria 1.

Projects that reduce car dependence, expand multimodal access consistent with the Envision Dublin Multi-Modal Thoroughfare Plan, or improve connectivity are prioritized. The Project Evaluation framework provides City staff with a consistent set of criteria to assess development proposals, including those that may deviate from the WID Special Area. The intent is to encourage flexibility, while ensuring that opportunities are evaluated holistically and transparently. JAN. FEB. MAR. APR. MAY JUN. JUL. AUG. SEP. OCT. NOV. DEC. Operating Budget Development Budget Development Continuous Monitoring The strategy should be regularly tracked for progress, assessed for effectiveness, and updated periodically. The diagram below illustrates how this could be integrated into the City's existing annual budget process. Monitoring & Updating This strategy was developed using available planning, engineering, and market information as of April 2026. The strategy should be monitored regularly for implementation progress, effectiveness, and relevance. As development intensity increases, utility infrastructure should be reassessed against the assumptions established in Envision Dublin. All road alignments identified in this strategy are conceptual and will require further study and design as development advances. Key milestones, such as significant progress on the PARC, may necessitate an update. As conditions evolve, development interest accelerates, or new studies refine infrastructure assumptions, the strategy should be updated to reflect current conditions and evaluated on a case-by-case basis. Adopt Plan Evaluate Plan Prepare Update Strategy Management CIP Budget Development 37 Phasing Approach Phasing Overview • Phase 1: Site Readiness and Core Infrastructure • Phase 2: Catalytic and Anchor Developments • Phase 3: Ecosystem Buildout Phase 1: Site Readiness and Core Infrastructure Phase 1 focuses on establishing the foundational conditions necessary for development to occur. Investments in this phase are targeted to remove critical constraints and create confidence in the district’s readiness. Phase 1 investments are designed to set the stage for private development without overbuilding infrastructure ahead of demand. Primary actions include: • Advancing priority utility extensions and roadway improvements that unlock multiple development sites (see Priority Matrix) • Establishing district access, internal connectivity, and initial public realm improvements • Implementing regulatory adjustments and governance structures needed to support development review and coordination • Aligning near-term capital investments with the most development- ready Opportunity Areas The Phasing Approach provides a flexible roadmap for advancing development in the WID over time. Rather than a rigid timeline, the phasing framework aligns physical readiness with policy intent to guide investment decisions. The approach recognizes that implementation will be iterative and overlapping, influenced by market demand, funding availability, and regional coordination. Phase 2: Catalytic and Anchor Developments Phase 2 is defined by visibility. Where Phase 1 removes constraints, Phase 2 demonstrates through built projects that the WID is open, investable, and distinct. The Premier Athletic and Recreation Campus (PARC) and the multimodal hub are the anchors of this phase not simply because they are large investments, but because they generate the kind of activity, identity, and foot traffic that signals to the private market that the district has arrived. A company evaluating a site decision responds to evidence of commitment. Phase 2 provides that evidence. Primary actions include: • Construction of PARC as a multi-use destination that activates the district's core and demonstrates placemaking quality • Advancement of the multimodal hub to establish multimodal access and catalyze transit-oriented development on adjacent Dublin- owned parcels • Targeted utility and roadway upgrades that extend Phase 1 core infrastructure into Opportunity Areas 2A and 2B • Intensified engagement with private developers to align site development timing with infrastructure delivery Phase 3: Ecosystem Buildout Phase 3 represents longer-term buildout as infrastructure networks mature and development demand expands across the district. Phase 3 reinforces the WID as a complete, resilient innovation ecosystem rather than a single-purpose employment area. Primary actions include: • Expansion into additional Development Areas as capacity and access are established • Delivery of complementary uses, services, and amenities that support workforce attraction and retention • Incremental completion of internal street networks, public spaces, and quality-of-life infrastructure • Continued adaptation of priorities based on market conditions and regional growth 38 To: Members of Dublin City Council From: Megan D.

Hendershot, P.E., Director of Utilities & Stormwater Management Chris Will, AICP, Senior Planner Jenna Goehring, Economic Development Administrator Zach Hounshell, Planner II Mara Hunter, Management Analyst Re: West Innovation District Integrated Implementation Strategy - Update Overview Following the November 2025 City Council Retreat and review of recommendations, a final draft of the West Innovation District Integrated Implementation Strategy (WIDIIS) was prepared. The strategy is intended to advance the principles and recommendations outlined in Envision Dublin to help guide West Innovation District (WID) development in a way that supports long-term goals with greater predictability. It focuses on refining infrastructure needs by aligning ongoing transportation, water and sanitary sewer planning efforts to ensure infrastructure adequately supports future development. In addition, the process coordinates projects within the WID by analyzing planning and development activity across the WID Area Boundary, including how growth in neighboring jurisdictions may influence the District’s future. The purpose of this meeting is to share the final draft of the West Innovation District Integrated Implementation strategy prior to returning to City Council with a final strategy for review and adoption. Background In 2024, City Council adopted the Envision Dublin Community Plan, which includes land use recommendations, roadway improvements, infrastructure needs, economic growth and parks and open space recommendations. The Community Plan update was an extensive process spanning eighteen months with a focus on community engagement, coordination with other plans and policies, collaboration with surrounding jurisdictions and updates to six Special Area Plans, including the WID. The draft Community Plan was reviewed by the Envision Dublin Steering Committee, and the Planning and Zoning Commission recommended approval to City Council for Office of the City Manager 5555 Perimeter Drive • Dublin, OH 43017-1090 Phone: 614-410-4400 • Fax: 614-410-4490 Memo Memo – West Innovation District Integrated Implementation Strategy Update April 7, 2026 Page 2 of 6 adoption. The Community Plan, as it pertains to the WID, increased area plan boundaries, focuses on recommendations that support the City’s Economic Development Strategy, highlights the potential future rail site, recommends a mixed-use center adjacent to Ohio University’s Dublin Campus, incorporates increased flex innovation uses to promote additional employment opportunities and provides uses that transition from a higher intensity of development within the Ohio University/U.S. 33 corridor. In 2025, City Council adopted Res. 01-25, establishing five visionary goals, one of which was to Accelerate Economic Development in the West Innovation District. The purpose of this goal was to spur development and infrastructure investment in the District by developing a strategic implementation plan that leverages the District's premier location, regional connectivity and partner institutions. As a result of this goal, the City contracted with Planning NEXT, with support from EMH&T, to create the WIDIIS, combining the City’s strategic framework, Envision Dublin, the Economic Development Strategy, the Housing Study and Strategy, transportation networks, the WID Special Area Plan and the Ohio Environmental Protection Agency State Water Quality Management Plan. The WIDIIS process began with a comprehensive review of adopted plans, technical studies and active infrastructure initiatives relevant to the WID. This initial effort established a shared understanding of existing conditions, validated key assumptions from Envision Dublin, and clarified how concurrent efforts, such as water and sanitary sewer utility master planning, would inform and support the strategy's development. An orientation workshop and site tour with City staff followed, grounding the project team in the District’s physical conditions, development patterns, and market dynamics. Through this early work, priority sites were identified based on ownership, development interest, and alignment with City objectives. The project team then engaged directly with stakeholders through focused interviews with institutional partners, neighboring jurisdictions and City Council members. These conversations helped identify priorities, constraints, and implementation considerations, and informed assumptions about market readiness, infrastructure timing, and regulatory needs. Throughout the process, ongoing coordination with City staff and the consultant teams ensured alignment across concurrent planning efforts within the WID. Council’s policy direction in 2025 also prompted several studies and strategies intended to aid in the implementation of their visionary goal. Throughout 2025, staff members have undertaken efforts to focus on master planning (Premier Athletic and Recreation Campus, which is following the WIDIIS timeframe, West Dublin Rail Station), utility and infrastructure planning (WIDIIS, Water and Sanitary Sewer Utility Master Plans) and thoroughfare planning (University Boulevard Extension, Signature Trail Alignment, ODOT’s 161 Corridor Study, New Road 4 Alignment, Cosgray Road Improvements). Staff members have also recently engaged with neighboring jurisdictions on the SR 161 Corridor Study to coordinate on various planning efforts. Although several consultants are engaged with each project, Staff members and Planning NEXT have collectively captured the work and recommendations for each project under the ‘umbrella’ of the WIDIIS as a coordinated, focused effort. In 2026, City Council refined their goal to Catalyze Economic Development in the West Innovation District. Since its refinement, the project team has continued to refine the WIDIIS to advance strategic infrastructure and development initiatives to unlock the District’s full economic and innovation potential. The final version of the WIDIIS was drafted as a result of all of these efforts. Memo – West Innovation District Integrated Implementation Strategy Update April 7, 2026 Page 3 of 6 Strategy Document Introduction The WID is Dublin’s primary opportunity for long-term economic growth and innovation. Located along the City’s western edge and encompassing approximately 2,250 acres, the District is intended to enable employment-generating uses focused on research, technology, and innovation that complement surrounding neighborhoods and regional economic activity. City Council’s 2025 and 2026 goals to accelerate and catalyze economic development in the WID underscored the need for a clear and coordinated approach to infrastructure investment and implementation. The Strategy builds on the policy direction established in the Community Plan and the adopted West Innovation District Special Area Plan by translating those policies into an actionable framework. Rather than revisiting land use decisions, it clarifies how infrastructure investments should be sequenced, how development may advance over time, and how public and private investments can be aligned to support site readiness, orderly growth, and the District’s role as Dublin’s premier employment and innovation center. Framework The WIDIIS framework is organized around four integrated components that guide implementation. Together, these components align policy, infrastructure planning, and development activity to support implementation of the WID vision: Innovation Innovation establishes the economic direction for the WID and guides policy and investment decisions by aligning development with Dublin’s broader innovation ecosystem. Innovation districts concentrate jobs, talent and collaboration to drive high-value economic growth, building on Dublin’s and the Columbus Region’s strengths in advanced manufacturing, logistics, software and life sciences. At approximately 2,250 acres, the WID is larger than a typical innovation district Memo – West Innovation District Integrated Implementation Strategy Update April 7, 2026 Page 4 of 6 and therefore requires a differentiated approach, offering space, infrastructure and flexibility not available elsewhere in the city. As one of Dublin’s seven business districts, it supports innovation along a continuum and scaled production, and the Implementation Strategy positions the WID as a critical link within Dublin’s innovation portfolio, bridging early-stage innovation with long-term economic growth. Character Areas Character Areas define the intended role and identity of different parts of the District, guiding land use patterns and relationships among places. As previously seen by City Council, the character areas designate areas where strategic nodes of development can foster innovation and collaboration, where certain areas of the District can capitalize on opportunistic economic development, and where the City can monitor and help align regional growth outside the boundaries of the WID. Infrastructure Opportunity Areas Infrastructure Opportunity Areas identify locations with shared infrastructure conditions and investment needs, helping prioritize public improvements. This component was previously shared with City Council at the November 2025 Council Retreat, and separates the WID and WID+ areas between land that can be immediately serviced with public infrastructure today (Opportunity Area 1), to areas outside the existing WID boundaries that require both regional and utility partnership coordination (Opportunity Areas 4 & 5). This component is specific in the infrastructure expansions required to align with the recommendations of land use in the Envision Dublin Future Land Use Plan and the recommendations of public transportation networks within the Envision Dublin Thoroughfare Plan. Development Areas Development Areas apply this guidance at the parcel level, illustrating how individual sites may advance through coordinated public and private investment. The development areas are based on the boundaries of the WID Special Area Plan and splits the land into 10 development areas. Each area includes public infrastructure needed for full development buildout consistent with the recommendation assumptions of the Future Land Use Plan, as well as cost estimates for public infrastructure. In addition to the development areas within the strategy, a GIS Web Experience has also been created. This interactive tool is designed to support the City’s evaluation of potential utility extension scenarios, enabling interactive exploration of alternative build-out configurations at a planning level. The platform was specifically created to support the City in discussions with developers and capital planning decisions. A demo of the GIS tool will be provided during the presentation. Implementation The WIDIIS embeds the District’s priorities into the City’s core decision-making processes by aligning capital project planning, development review budgeting, and state and local economic incentives. Tools such as the Capital Improvement Plan, development review processes, annual work programs and state and local economic development support programs guide infrastructure investment and development sequencing to support predictable and coordinated outcomes. Supporting tools, including interactive mapping and consistent reference materials, provide clarity on investment priorities and development expectations as the District builds out. Implementation is supported by a flexible phasing approach that aligns physical readiness with Memo – West Innovation District Integrated Implementation Strategy Update April 7, 2026 Page 5 of 6 policy intent rather than relying on a fixed timeline. Development is expected to occur incrementally and, in some cases, concurrently, with timing influenced by market conditions, funding availability, and regional coordination. The priorities matrix in the WIDIIS identifies the critical infrastructure investments that either enable development to occur or represent opportunistic moves that unlock multiple areas simultaneously. Timing will respond to market demand, funding availability and private development interest. While multiple projects may advance concurrently, the priorities matrix identifies the sequence in which infrastructure investments should occur. Next Steps Following the April 13 City Council meeting, the project team will incorporate Council’s feedback and complete final edits to finalize the strategy document. The team plans to return to Council to share the final draft document for review and adoption. Recommendation Staff is seeking feedback from council on the following discussion questions: Memo – West Innovation District Integrated Implementation Strategy Update April 7, 2026 Page 6 of 6 1. Is Council supportive of the direction of the WIDIIS? 2. Are the recommendations clear on what is necessary to implement infrastructure in the District? 3. Are there other infrastructure priorities that Council would like clarity on or would like to be seen as a priority in the matrix? 4. Are there additional considerations Council would like to be included in the WIDIIS?
