HomeMy WebLinkAboutPlanning 2023-09-28 Item 7.2 - Utilities Element - Staff Report and AttachmentsCity of Tukwila Allan Ekberg, Mayor Department of Community Development - Nora Gierloff, AICP,, Director TO: Planning Commission FROM: Nancy Eklund, AICP, Long Range Planning Manager DATE: September 12, 2023 SUBJECT: Tukwila 2024-2044 Comprehensive Plan — Draft Utilities Element ISSUE This is a briefing to the Planning Commission on the proposed updates to the Utilities Element of the Comprehensive Plan. BACKGROUND Public Works, TIS, and Community Development Department Staff have been updating the Utilities Element. There are only a few changes in this element, largely reflecting updates due to information being no longer accurate or current, new "best practice" information, and updated guidance from regional policy document (King County Countywide Planning Policies and Vision 2050). Other items to note about the draft element: • Implementation Strategies - This Element will also contain Implementation Strategies, however those continue to be refined by the various departments to ensure that they are consistent with intended work programs by City Departments. The final list will be provided to the PC later this year. • This Element is currently #12 in the Comprehensive Plan. Because we are consolidating the various elements, that numbering has been removed for the draft. When we finalize the plan, the Element will be renumbered. • The footnotes in Clean version may be relevant only for the track changes version. RECOMMENDATION Staff recommends that the Planning Commission consider the draft Utilities Element and move it forward to a later date in late winter 2024 when the entire draft Plan (including the Implementation Strategies) will be available for review, followed by a public hearing.

PURPOSE The availability and adequacy of utility facilities and services are closely linked to other comprehensive plan elements and goals. The City of Tukwila provides a range of utility facilities and services and also relies on other public and private agencies to provide many of these services. Sewer, water, surface water management, solid waste, electricity, natural gas and telecommunications are addressed in this Element. Policies pertaining to utilities and vegetation are located in the Natural Environment element. The Utilities Element profiles both City and non -City -owned utilities operating within Tukwila. Sewer and water services are provided by the City, adjacent municipalities, and special districts. Surface water drainage is managed locally, but with interjurisdictional and watershed wide cooperative planning and management. The remaining utilities are provided to residents and businesses through franchise agreements between the City and service providers. The Utilities Element establishes a basis for decision-making that is consistent with Washington's Growth Management Act, the Puget Sound Regional Council's Vision 2050, and King County's Countywide Planning Policies, including targets for housing units and employment, which are a basis for determining demand for utility services and infrastructure. These State and regional requirements are fulfilled by the Utilities Background Report, Comprehensive Sanitary Sewer Plan, Comprehensive Water Plan, and the Surface Water Comprehensive Plan. These documents, along with the six-year Capital Improvement Program and the City of Tukwila budget, are adopted by reference in Tukwila's Comprehensive Plan.

SURFACE WATER City of Tukwila ELECTRICITY Puget Sound Energy Seattle City Light NATURAL GAS Puget Sound Energy REGULATORY REQUIREMENTS This element is consistent with Washington State GMA, PSRC Vision 2050, and King County County -wide Planning Policies requirements for utilities planning, based on housing and employment targets. These requirements are fulfilled by the following documents: Utilities Background Report Comprehensive Sanitary Sewer Plan Comprehensive Water Plan Comprehensive Surface Water Management Plan ISSUES Several key issues in meeting the utility needs of the City are addressed in this Utilities Element: Service Extensions. Planned extensions of utility services are based on existing needs, or to accommodate planned growth or growth targets. Coordination of Service Providers. The City -managed utilities must coordinate with adjacent providers that provide utility services to portions of the City. Coordination among Tukwila's three non -City sewer and five non -City water districts is critical. Concurrency and Implications for Growth. Utility projects and other capital facilities must be developed so that improvements are in place by the time they are needed, to address growth and to accommodate growth targets. Environmental Sustainability. Utility planning and operations requires compliance with federal and state laws including the Clean Water Act, NPDES, ESA, State Waste Discharge Permit, and contribute to watershed -wide restoration efforts to preserve the quality of the natural environment.

Residential Neighborhood and Sub -Area Vitality. City -planned utility improvements and extensions place priority on improving and sustaining residential neighborhood quality and livability. Utility investments affect neighborhood quality of life and the ability to realize established visions for specific sub -areas. System Rehabilitation, Replacement, and Retrofit. Much of the City's utility infrastructure has reached or is near its life expectancy. Rehabilitation or replacement of these systems is needed to ensure their continued reliability. Federal, State and, local polices require utility system improvements to comply with new regulations. SYSTEM DESCRIPTIONS WATER AND SEWER The City of Tukwila purchases all of its water from the Cascade Water Alliance under a contract through the year 2064. Tukwila's Comprehensive Water System Plan identifies areas of water supply and distribution deficiency, and the six-year Capital Improvement Plan proposes corrective improvements. See Map 12-1. The Tukwila sewer system is exclusively a collector system with no treatment component. King County DNRP Wastewater Treatment Division provides Regional wastewater treatment at the South Treatment Plant in Renton. The Comprehensive Sewer System Plan identifies deficiencies in the system, and corrective improvements are proposed in the six-year Capital Improvement Plan. See Map 12-2. Certain areas of the City are served by other water and sewer providers, which develop their own plans in coordination with the City of Tukwila. Tukwila's Comprehensive Water System and Sewer System Plans are adopted by reference as part of the Comprehensive Plan. Those system plans identify present and future improvements and establish certain required levels of service and priorities for system improvements. Level of service standards are also established by applicable Board of Health regulations, the Uniform Plumbing Code, and the Uniform Fire Code. Consistent with State mandates, Tukwila revises and updates system plans to assure consistency with the Comprehensive Plan and the Capital Improvement Program. SURFACE WATER MANAGEMENT Tukwila's surface water system consists of both built stormwater drainage infrastructure and surface waters such as rivers and creeks. All of the city's sub -basins drain to the the Green/Duwamish River. For locations of surface water management facilities, see Map12-3.

The Surface Water Comprehensive Plan contains an inventory of existing facilities and identifies current system deficiencies and planned improvements. It evaluates the system under present development conditions and identifies remedies for segments of the system where problems exist or are likely to develop in the future as a result of growth and development. Proposed improvements are included in the Six -Year Capital Improvement Program (CIP). The City reviews and updates its Surface Water Management Plan annually to assure consistency with this Plan, State and local regulations, the CIP, and other ongoing City planning processes. Map 12-1: Water Districts Map 12-2: Tukwila Sewer System Map 12-3: Surface Water Management Facilities Image TURNING WASTE INTO ENERGY King County's Cedar Hills Landfill is the destination for much of Tukwila's solid waste. The landfill has a gas -to -energy project which leads to cleaner air and reductions in greenhouse gas emissions. In 2021, the landfill generated an average of about 6,500 standard cubic feet per minute of landfill gas. This gas is transmitted to the Bio Energy Washington (BEW) gas -to -energy plant and converted into pipeline -quality biogas. The renewable gas produced equals the amount of energy needed to meet the natural gas needs of over 17,500 homes in King County. Image source: King County Solid Waste Division SOLID WASTE Solid Waste collection, transportation and disposal in Tukwila is governed by State and local regulations, an interlocal agreement with King County, and collection contracts with solid waste providers. Through a competitive ten-year contract with the City, as of November 1, 2023, Recology provides comprehensive garbage, recyclings, and food and yard waste collection services to residential, multifamily, and commercial customers. Residential garbage collection is voluntary. The City's solid waste is ultimately taken to King County's Cedar Hills Landfill for disposal. As part of the Solid Waste Interlocal Agreement (ILA) with King County, Tukwila and other parties Page 4 of 14 https://tukwilawa.sharepoint.com/sites/departmentofcommunitydevelopment/dcdplanning/long range planning/2024 comprehensive plan/00 - planning commission coordination/2023-09-28 mtg/utilities element/utilities -12 -single column (track changes 9-13-23).d 34 UTILITIES Existing Comprehensive Plan (with proposed changes) * Provide references (source, date, page) for all data added * Footnotes include explanations for why text was changed, as well as references the source of the addition. will develop plans and alternatives to waste disposal at Cedar Hills Landfill in advance of its closure in 2038. ELECTRIC POWER Electric power involves both transmission systems and distribution systems. Tukwila's electric power is provided by Puget Sound Energy, with approximately 3,800 customers, and Seattle City Light, serving approximately 5,700 residential and 1,000 commercial customers in Tukwila. Both companies operate under non-exclusive franchise agreements with the City. See Map 12-4. Electrical Service Providers Map 12-4: Electric Service Providers Plans from both Seattle City Light and Puget Sound Energy place a priority on using energy conservation as a way to increase service capacity. Puget Sound Energy estimates that half of its long-term need for electric power can be met by energy efficiency and additional wind -power. The rest is likely to be met with added natural gas-fired resources. To meet future demand, some new transmission lines and substations will be built in Tukwila, and existing ones rebuilt and/or maintained. Distribution plans include line and station projects. Future distribution improvements will be required to meet the demands of Tukwila's projected growth. Seattle City Light's plans for future distribution capacity include additional feeder capacity that is expected to meet demand in Tukwila through the year 2031. Seattle City Light intends to meet electrical load growth through conservation and new generation resources powered by renewable energy. NATURAL GAS Puget Sound Energy, an investor-owned utility, builds, operates and maintains natural gas facilities serving approximately 3,400 customers in Tukwila. Puget Sound Energy covers virtually all of Tukwila with their main distribution lines. The utility foresees no difficulties in meeting future demand during the planning period. No major improvement projects are planned at this time. For natural gas service areas in Tukwila, see Map 12-5. TELECOMMUNICATIONS As telecommunications technologies have evolved, convergence of these technologies has occurred, resulting in multiple communication services migrating into consolidated networks. Telecommunications in Tukwila includes both wired and wireless telephone services, cable and satellite television, and high-speed broadband technology. Through partnerships with franchised telecommunications companies, internal public works projects and completion of capital projects, the City has a robust conduit infrastructure that would enable and facilitate Page 5 of 14 https://tukwilawa.sharepolnt.com/sites/departmentofcommunitydevelopment/dcdplanning/long range planning/2024 comprehensive plan/00- planning commission coordination/2023-09-22 mtg/utilities element/utilities-12 -single column (track changes 9-13-23).docx 35 UTILITIES Existing Comprehensive Plan (with proposed changes) * Provide references (source, date, page) for all data added * Footnotes include explanations for why text was changed, as well as references the source of the addition. future fiber optic connectivity projects benefitting the City, its residents and businesses, and project partners. The City has joined a connectivity consortium of cities and other public partners that would construct and maintain a regional fiber-optic telecommunications system. This fiber-optic system would provide redundancies, enhance communications networks, and emergency operations. Natural Gas Provider Map 12-5: Natural Gas Service CABLE AND SATELLITE TELEVISION The City of Tukwila has a non-exclusive franchise agreement with Comcast Corporation to construct, operate and maintain a cable system in compliance with Federal Communications Commission (FCC) regulations. Comcast's network provides high-definition television capacity and high-speed internet access through cable modems, and includes coaxial and fiber optic cabling systems deployed both underground and overhead using utility poles leased from power and telephone companies. Satellite television competes directly with cable television by delivering hundreds of channels directly to mini -dishes installed in homes and businesses throughout Tukwila. WIRELINE AND WIRELESS COMMUNICATIONS Many companies offer telecommunications services including integrated voice and data, and voice over internet protocol(VoiP) technology. CenturyLink, the Incumbent Local Exchange Carrier (ILEC), is now joined by several Competitive Local Exchange Carriers (CLECs) in providing more communications service options to Tukwila residents and businesses. With expansion of telecommunications infrastructure, new technologies and competition, telecommunications utilities are expected to meet voice, video and broadband demands during the planning period. GOALS, POLICIES AND STRATEGIES GOAL 1 Utility services and facilities that meet the community's current and future needs in a safe, reliable, efficient, economic, and environmentally responsible manner.

UTILITIES NOT OPERATED BY THE CITY Aside from water, sewer and surface water management, most utilities serving the residents of Tukwila are not owned or operated by the City. While the City can provide input on planning efforts for these utilities, it does not directly control service rates or the exact location of new infrastructure. Private utilities are required to obtain any City permits necessary to operate or install infrastructure within the City and must comply with all applicable City and State regulations. Image Source: Puget Sound Energy ➢ POLICIES FOR NON -CITY -OWNED UTILITIES Non -City -owned utilities develop strategic and operational plans with varying degrees of input and involvement from the City. They set capacity and service levels on an area -wide basis, and rely on the local government's involvement to ensure that capacity is sufficient. As a condition of applying for a permit, new development that uses non -City owned water and sewer utilities is required to obtain a letter of service availability. This letter establishes that utility service meeting City standards is either available or will be available prior to occupancy.

The electric power and natural gas utilities project adequate capacity during the 20 -year planning period, assuming responsible use of these resources. Electric utility capacity is set regionally, with Tukwila's needs determined and provided for as part of an area -wide system. Similarly, natural gas is provided via a regional delivery system. With new technologies, telecommunications utilities project virtually limitless capacity within the planning horizon. Through long-term Interlocal Agreements (ILAs), the solid waste system will continue to be upgraded to meet Tukwila's current and future needs. The Cedar Hills Landfill expects to reach full capacity in 2025. The current ILA that expires in 2040 addresses the process that cities and King County will follow to develop disposal options prior to Cedar Hills Landfill reaching its full capacity. Tukwila and other suburban cities participate in planning and contribute to reaching regional goals via their recycling and waste reduction strategies and practices. General Policies Policy 1.32 Actively coordinate project implementation with individual utilities, based on Tukwila's Comprehensive Plan and development regulations. Policy 1.33 Require new development that uses non -City -owned water and sewer utilities to obtain a letter of service availability as a condition of receiving a Tukwila permit. Policy 1.34 Require utilities operating in the right-of-way to obtain a franchise that includes service levels and requirements meeting Comprehensive Plan forecasts and other applicable federal, State, and local regulations. Policy 1.35 Encourage utilities to consolidate facilities, use existing transportation corridors, and minimize visual impacts of facilities, where technically feasible.

The City of Tukwila provides a range of utility facilities and services and also relies on other public and private agencies to provide many of these services. Sewer, water, surface water management, solid waste, electricity, natural gas and telecommunications are addressed in this Element. Policies pertaining to utilities and vegetation are located in the Natural Environment element. The Utilities Element profiles both City and non -City -owned utilities operating within Tukwila. Sewer and water services are provided by the City, adjacent municipalities, and special districts. Surface water drainage is managed locally, but with interjurisdictional and watershed wide cooperative planning and management. The remaining utilities are provided to residents and businesses through franchise agreements between the City and service providers. The Utilities Element cstablislestablishhes a basis for decision-making that is consistent with Washington's Growth Management Act, the Puget Sound Regional Council's Vision 2050, and King County's Countywide Planning Policies, including targets for housing units and employment, which are a basis for determining demand for utility services and infrastructure. These State and regional requirements are fulfilled by the Utilities Background Report, Comprehensive Sanitary Sewer Plan, Comprehensive Water Plan, and the Comprehensive Surface Water Management Comprehensive Plan. These documents, along with the six-year Capital Improvement Program and the City of Tukwila budget, are adopted by reference in Tukwila's Comprehensive Plan.

Add all explanations of changes as footnotes. Coordination of Service Providers. The City -managed utilities must coordinate with adjacent providers that provide utility services to portions of the City. Coordination among Tukwila's three non -City sewer and five non -City water districts is critical. Concurrency and Implications for Growth. Utility projects and other capital facilities must be developed so that improvements are in place by the time they are needed, to mcctaddress growth and to accommodate growth targets. Environmental Sustainability. Utility planning and operations requires environmental compliance with federal and state laws including the protectionClean Water Act, NPDES, ESA, State Waste Discharge Permit, and contribute to-ai4watershed--wide restoration efforts; to preserve the quality of the natural environment vitality. Residential Neighborhood and Sub -Area Vitality. City -planned utility improvements and extensions place priority on improving and sustaining residential neighborhood quality and livability. Utility investments affect neighborhood quality of life and the ability to realize established visions for specific sub -areas. System Rehabilitation, Replacement, and Retrofit. Much of the City's utility infrastructure has reached or is near its life expectancy. Rehabilitation or replacement of these systems is needed to ensure their continued reliability. Federal, State and, local polices require utility system improvements to comply with new regulations. SYSTEM DESCRIPTIONS WATER AND SEWER The City of Tukwila purchases all of its water from the Cascade Water Alliance under a contract through the year 2064. Tukwila's Comprehensive Water System Plan identifies areas of water supply and distribution deficiency, and the six-year Capital Improvement Plan proposes corrective improvements. See Map 12-1. The Tukwila sewer system is exclusively a collector system with no treatment component. King County DNRP Wastewater Treatment Division provides Regional wastewater treatment at the South Treatment Plant in Renton. The Comprehensive Sewer System Plan identifies deficiencies Page 3 of 18 https://tukwilawa.sharepoint.com/sites/depertmentorcommunitvdevelopment/dcdplannine/lone ranee plannine/2024 comprehensive plan/00 - Planning commission coordination/2023-09-28 mtg./utilities element'utilit.es -t? - single colurm.docx 47 added UTILITIES Chapter 12 Provide references (source, date, page) for all data Add all explanations of changes as footnotes.

Certain areas of the City are served by other water and sewer providers, which develop their own plans in coordination with the City of Tukwila. Tukwila's Comprehensive Water System and Sewer System Plans are adopted by reference as part of the Comprehensive Plan. Those system plans identify present and future improvements; and establish certain required levels of service and priorities for system improvements. Level of service standards are also established by applicable Board of Health regulations, the Uniform Plumbing Code, and the Uniform Fire Code. Consistent with State mandates, Tukwila revises and updates system plans to assure consistency with the Comprehensive Plan and the Capital Improvement Program. SURFACE WATER MANAGEMENT Tukwila's surface water drainage system consists of both built stormwater drainage infrastructure drainage improvements and the natural drainage of the areasurface waters such as rivers and creeks. Except for a small area in the Ryan Way neighborhood, All of the city's sub - basins drainage drain to the is ultimately to the Green/Duwamish River. For locations of surface water management facilities, see Map12-3. The Comprehensive Surface Water Management Comprehensive Plan contains an inventory of existing facilities and identifies current system deficiencies and planned improvements. It evaluates the system under present development conditions and identifies remedies for segments of the system where problems exist or are likely to develop in the future as a result of growth and development. Proposed improvements are included in the Six -Year Capital Improvement Program (CIP). The City reviews and updates its Surface Water Management Plan annuallyregularly to assure consistency with this Plan, State and local regulations, the CIP, and other ongoing City planning processes.

Map 12-3: Surface Water Management Facilities Image source: King County Solid Waste Division} TURNING WASTE INTO ENERGY King County's Cedar Hills Landfill, which is the destination for much of Tukwila's solid waste.r-s also the site of the nation's third largest landfill gas energy project. Methane gas from garbage is processed and purified, then sold to Puget Sound Energy power plants to be used to generate electricity. The landfill has a gas -to -energy project which leads to cleaner air and reductions in greenhouse gas emissions. In 2021, the landfill generated an average of about 6,500 standard cubic feet per minute of landfill gas. This gas is transmitted to the Bio Energy Washington (BEW) gas -to -energy plant and converted into pipeline -quality biogas. The renewable gas produced equals the amount of energy needed to meet the natural gas needs of over 17,500 homes in King County. Converting landfill gas to electricity in this way reduces the landfill's greenhouse gas emissions and provides additional revenue to the County's Solid Waste Division, keeping disposal rates low for residents across King County. Image source: King County Solid Waste Division SOLID WASTE Solid Waste collection, transportation and disposal in Tukwila is governed by State and local regulations, an interlocal agreement with King County, and collection contracts with solid waste providers. Through a competitive tend+ -year contract with the City, as of November 1, 2023, Recology provides comprehensive garbage, recyclingyclables, and food and yard_ waste collection services to residential, multi -family, and commercial customers. Residential garbage collection is voluntary. Tukwila has considered implementing mandatory garbage collection to curb illegal dumping, litter and accumulation of trash/garbage on private property, but garbage collection remains Page 5 of 18 https://tukwilawa.sharenoint.com/sites/depertmentofcommunitvdevelopment/dcdplanning/lone ranee plannine/2024 comprehensive plan/00 - Planning commission coordination/2023-09-28 mreutilities element/utilities -12 - single column.docx 49 added UTILITIES Chapter 12 Provide references (source, date, page) for all data Add all explanations of changes as footnotes.

Approximately 75% of Tukwila residents subscribe to curbside garbage services, and the remaining 25% either self haul to King County's Bow Lake Transfer Station in Tukwila or use other disposal methods. The City's solid waste is ultimately taken to King County's Cedar Hills Landfill for disposal. As part of the Solid Waste Interlocal Agreement (ILA) with King County, Tukwila and other parties will develop plans and alternatives to waste disposal at Cedar Hills Landfill in advance of its closure in 2038. ELECTRIC POWER Electric power involves both transmission systems and distribution systems. Tukwila's electric power is provided by Puget Sound Energy, with approximately 3,800 customers, and Seattle City Light, serving approximately 5,700 residential and 1,000 commercial customers in Tukwila. Both companies operate under non-exclusive franchise agreements with the City. See Map 12=- 4. Electrical Service Providers Map 12-4: Electric Service Providers Plans from both Seattle City Light and Puget Sound Energy place a priority on using energy conservation as a way to increase service capacity. Puget Sound Energy estimates that half of its long-term need for electric power can be met by energy efficiency and additional wind -power. The rest is likely to be met with added natural gas-fired resources. To meet future demand, some new transmission lines and substations will be built in Tukwila, and existing ones rebuilt and/or maintained. Distribution plans include line and station projects. Future distribution improvements will be required to meet the demands of Tukwila's projected growth. Seattle City Light's plans for future distribution capacity include additional feeder capacity that is expected to meet demand in Tukwila through the year 2031. Seattle City Light intends to meet electrical load growth through conservation and new generation resources powered by renewable energy. NATURAL GAS Puget Sound Energy, an investor-owned utility, builds, operates and maintains natural gas facilities serving approximately 3,400 customers in Tukwila. Puget Sound Energy covers virtually all of Tukwila with their main distribution lines. The utility foresees no difficulties in meeting Page 6 of 18 https://tukwilawa.sharepoint.com/sites/depertmentorcommunitvdevelopment/dcdplanning/lone ranee plannine/2024 comprehensive plan/00 - Planning commission coordination/2023-09-28 mtg./utilities element/utilities -12 - single column.docx 50 added UTILITIES Chapter 12 Provide references (source, date, page) for all data Add all explanations of changes as footnotes.

TELECOMMUNICATIONS As telecommunications technologies have evolved, convergence of these technologies has occurred, resulting in multiple communication services migrating into consolidated networks. Telecommunications in Tukwila includes both wired and wireless telephone services, cable and satellite television, and high-speed broadband technology. Through partnerships with franchised telecommunications companies, internal public works projects and completion of capital projects, the City has a robust conduit infrastructure that would enable and facilitate future fiber optic connectivity projects benefitting the City, its residents and businesses, and project partners. The City has joined a connectivity consortium of cities and other public partners that would construct and maintain a regional fiber-optic telecommunications system. This fiber-optic system would provide redundancies, enhance communications networks, and emergency operations. Natural Gas Provider Map 12-5: Natural Gas Service CABLE AND SATELLITE TELEVISION The City of Tukwila has a non-exclusive franchise agreement with Comcast Corporation to construct, operate and maintain a cable system in compliance with Federal Communications Commission (FCC) regulations. Comcast's network provides high-definition television capacity and high-speed internet access through cable modems, and includes coaxial and fiber optic cabling systems deployed both underground and overhead using utility poles leased from power and telephone companies. Satellite television competes directly with cable television by delivering hundreds of channels directly to mini -dishes installed in homes and businesses throughout Tukwila.

UTILITIES NOT OPERATED BY THE CITY Aside from water, sewer and surface water management, most utilities serving the residents of Tukwila are not owned or operated by the City. While the City can provide input on planning efforts for these utilities, it does not directly control service rates or the exact location of new infrastructure. Private utilities are required to obtain any City permits necessary to operate or install infrastructure within the City and must comply with all applicable City and State regulations. Image Source: Puget Sound Energy POLICIES FOR NON -CITY -OWNED UTILITIES Non -City -owned utilities develop strategic and operational plans with varying degrees of input and involvement from the City. They set capacity and service levels on an area -wide basis, and rely on the local government's involvement to ensure that capacity is sufficient. As a condition of applying for a permit, new development that uses non -City owned water and sewer utilities is required to obtain a letter of service availability. This letter establishes that utility service meeting City standards is either available or will be available prior to occupancy. The electric power and natural gas utilities project adequate capacity during the 20 -year planning period, assuming responsible use of these resources. Electric utility capacity is set regionally, with Tukwila's needs determined and provided for as part of an area -wide system. Similarly, natural gas is provided via a regional delivery system. With new technologies, telecommunications utilities project virtually limitless capacity within the planning horizon.
