- OLDENSTATENETDesign Process ' Analyzed extensive mapping resources to understand: existing technical and telecom assets, road andhighway systems, topological factors, socioeconomic composition by region, broadband speeds (or lackthereof) by region, among other factors. Used CPUC middle-mile recommendation routes as anchors for most route solutions adding regional rings. Engaged with a diverse set of community groups to understand needs, requirements, existing assets, andpotential opportunities. Engaged service providers (carriers, vendors, ISPs, etc) to examine potential solution sets. Integrated proposed 18 projects into the initial statewide network recommendation. Identified regions where the unserved population is 50 miles from current design to build fiber paths wherefeasible. Estimated the cost for building proposed routes in preparation for an optimization analysis.

- OLDENSTATENETDesign Factors' Primarily utilize new fiber-optic cable construction where feasible (Caltrans Right of Way). Seek joint build partnerships to reduce costs to the state and to partners. Use long-term Dark Fiber IRUs where appropriate to reduce cost, time to service, and to addresiliency. Align to organizations with existing regional, state, and federal broadband infrastructure funding tomaximize investments, e.g. CASF-funded organizations. Aim for "early wins" to meet expectations of residents, policymakers, and other stakeholders. Utilize well-established best practices in network design principles, protocols, engineering, andoperation.

- OLDENSTATENETSupport for Optimization Process' Inform CDT to enable partner-based optimization and application of available budget. This includes: Providing comprehensive information to drive decision-making for Build vs. Buy vs. Joint Build Working with CDT to determine contingency reserve percentage against 3.28 budget (typically 10-20 /o)Steps to achieving optimization: Show total routes, mileage, and projected cost of statewide Middle Mile Network that would be 100% newly-built fiber,including required equipment and facilities Determine newly-built routes that are no regrets and most feasible within available budget Determine routes for dark fiber IRUs within remaining budget In addition, determine joint-build portions of MM network within remaining budgetFinal CDT decisions for all MM network segments within 3.28 budget (minus contingency): 18 Initial Projects Joint build routes Newly built fiber routes Equipment and facilities Dark Fiber IRU routes
