POLICIES AND ORDINANCES
THAT FACILITATE
BROADBAND DEPLOYMENT
Diane Kruse diane@NEOconnect.us
Policies and ordinances can be adopted by local governments to reduce the capital costs of broadband deployment. This paper discusses the best practices and impacts of implementing a dig once and/or shadow conduit policy, as well as other policies to consider for advancing broadband deployment.
1
Implement Policies and Ordinances that are Broadband Friendly
Municipalities and Counties have the power to significantly reduce the capital costs of
broadband infrastructure deployment. Whenever possible, cities and counties can put in
place policies and ordinances to help encourage broadband investment. These policies
can be implemented to facilitate investment from the private sector and can also be used
to gain substantial assets that can be leveraged for broadband deployment.
Sixty to eighty percent of a fiber optic network’s capital costs are in opening a trench, or
in directional boring or in burying conduit that will house fiber optic cable. Policies that
encourage placement of conduit or fiber optic cable when a trench is open eliminate
much of the capital costs for network deployment. By coordinating with other City,
County, or State capital projects, additional conduit can be placed within an open trench
when other work is being performed in the right of way. Types of projects where
additional conduit could be installed might include - sidewalk improvements, street
light and trails construction and maintenance, road construction and road widening
projects, and any underground utility project.
A “Dig Once” Policy or a Shadow Conduit Policy typically has the following
components:
• All public works or installation of other telecom, cable or utility infrastructure
allows for conduit to be placed on behalf of the local or State government and any
other entities that want to participate. If there is an open trench, the policy
provides for coordination of street cuts and excavations with utilities, public
works, developers, and other interested parties. This maximizes the opportunity
for broadband-specific conduit installation, while minimizing cost, community
disruption and damage to existing infrastructure.
• A notice period informing other entities that an open trench will be available for
placement of their conduit and/or fiber optic facilities.
INCREMENTAL COST TO INSTALL SHADOW CONDUIT
IS $2 - $7 PER FOOT.
COST TO INSTALL NEW CONDUIT AS A STANDALONE
PROJECT IS $25 - $35 PER FOOT.
TYPICALLY, SHADOW CONDUIT REPRESENTS 1-2% OF A
ROAD IMPROVEMENT’S TOTAL PROJECT BUDGET.
2
• Allows for shadow conduit to be placed on behalf of the local and/or State
government. The installation of empty and/or spare conduit by a public agency
when excavations occur in the public right of way, with the local government
agency’s costs limited to the incremental costs of the conduit only.
A standard, conduit-specification document can be developed that addresses capacity,
separation of facilities, proper sizing and placement. The specification document also
addresses access to the conduit with detailed provisions for vaults and all access points.
Cost sharing or cost recovery stipulations can be put in place for materials and labor
assignment. Engineering specifications and drawings that address conduit sweeps,
bend radius and physical placement requirements can be provided with the standard
conduit specification.
Additionally, various government agencies can establish Joint Trench Agreements and
Joint Build Agreements with other telecommunications, cable or utility providers. Cost
for placement of conduit or fiber will be shared amongst all entities, allowing each to
take advantage of the other’s trenching. Standardization of agreements for potential
owners of underground infrastructure, can be established to ensure all parties are aware
of joint trenching opportunities.
Examples of Government Agencies that have Implemented a “Dig
Once” Policy and the Results
There are hundreds of examples of municipalities, counties, states, and federal initiative
that are using smart conduit construction, “Dig Once” policies and/or shadow conduit
policies to gain assets and attract potential partners to improve broadband services
within the community.
Municipal Examples
The Cities of Santa Cruz, San Francisco, and Gonzales, California have all implemented
“Dig Once” policies. Codes in each City now provide for improved communication with
potential stakeholders, as well as mandatory installation requirements for excavators. In
Santa Cruz the policies mandate that City Staff communicate with all excavators in the
City, and coordinate trench access for interested parties. Further, City Staff are directed
to work with the construction contractors to create cost-effective upgrades in the City’s
Public Right of Way (PROW). The City of Santa Cruz has also identified the importance
of maintaining the integrity of the PROW, and will suspend standalone construction in
the PROW.
Taking a somewhat differing approach, the City of San Francisco’s “Dig Once”/joint
trench policy amends the City’s Public Works Code to guarantee participation and
coordination by utility contractors. Approval by the Public Works Department and the
Department of Technology are required for all applications. Acceptance of plans is
3
contingent on compatibility with installation requirements, and with technical
specifications. City projects are evaluated with a right of way management system, and
by close cost-benefit analysis, to identify, coordinate, and prioritize PROW construction
efforts. The policy also includes a 5-year moratorium on excavating streets that have
been reconstructed, repaved, or resurfaced.1 The ultimate outcome of these policy
amendments is that contractors collaborate with the Department of Technology, which
covers all incremental costs, to install conduit for use by the Department, and also for
future leased facilities.
The City of Gonzales, CA requires all excavators in the Public Right of Way to install
telecommunications conduit, and has instituted common engineering specifications for
these projects. All material and installation specifications are determined by these
policies, and costs are covered by Public Works. Additionally, the City scrutinizes each
potential project for cost benefit and suitability, prior to approval.
The City of Brentwood, CA has had a conduit policy in place since 1999, and has
extended conduit to over 8,000 homes and businesses. The process began with
installations in new home developments, and has expanded across the city footprint. In
2015, the City began offering Gigabit services in partnership with Sonic.net, a Santa
Rosa-based, service provider. Sonic has a lease agreement with the City to install fiber
throughout City conduit and to provide residential and commercial services. In addition
to providing a lease revenue stream to the City, Sonic will also provide Gigabit Services
to the City at no charge, saving around $15,000 per year.2 Additionally, in those
neighborhoods with subscription rates over 30%, the local school will also receive
Gigabit Internet at no charge.3
In Centennial, CO, the City began a fiber optic and conduit initiative in 2008 as a public
works effort connecting city buildings, traffic signals and other public facilities. The City
implemented a “Dig Once” policy that required additional conduit be installed when
work was being done in the right of way. To date, the City has installed more than 60
miles of conduit and fiber optic infrastructure suitable for broadband deployment while
spending less than $600,000. This network is currently valued well over $6 Million. The
City recently engaged in a formal process to incent providers to deploy a Gigabit-
enabled fiber network to every home and business within the city limits. The City
announced an agreement with Ting, an Internet Service Provider. Ting is now using
existing City conduit and fiber to roll out its Gigabit services to the community.

The City of Arvada implemented shadow conduit implementation policies in 2017. The
City has placed a priority on connecting its key government facilities, several smart city
applications, its schools, parks and recreation and emergency first responder locations
with fiber optic cable. The total cost to implement this network is estimated at $13
Million; of which, $9 Million is in the form of directional boring and conduit installation.
As a way to reduce these capital costs, the City is working with the private sector to
share in the cost of installation of conduit on key routes throughout the City.
As the community of Mesa, Arizona, began to grow, community leaders recognized that
telecommunications would be a key element to its success. Mesa was an early adopter of
“Dig Once” policy, placing conduit whenever streets were excavated for any other
infrastructure purpose. Mesa has also taken advantage of non-traditional existing
infrastructure, planting fiber in abandoned conduit that had been used for other utility
purposes. This resulted in a network of 150 - 200 miles of fiber throughout the
community. The investment has paid off in numerous ways over time and helped the
city establish a broadband-friendly environment for economic development, allowing
private sector companies to use the existing conduit and fiber to reduce their overall
costs of infrastructure deployment.
Bozeman, MT invested in multi-duct conduits, making it possible for nonprofit Bozeman
Fiber, who leases the conduit, to reach more residences and businesses with service.
Lincoln, Nebraska invested $700,000 to install a conduit system in 2012. Since then, their
conduit network has grown to more than 300 miles, and has attracted six private carrier
providers who lease the conduit, and who are helping to pay off the initial investment.
County Examples
In California, neighboring Santa Cruz and San Benito Counties have both adopted “Dig
Once” Policies. Santa Cruz County has implemented ordinances that provide for
conduit installation during all underground and repaving construction. The language of
the ordinance states, in part: All construction, reconstruction or repaving of a County right-of-
way will include provisions for the installation of telecommunications cable, conduit and other
related equipment wherever practical and feasible…If a project includes excavation in or adjacent
to a County right-of-way, installation of or upgrades to telecommunications cable, conduit or
other infrastructure will be included as needed.4 San Benito County has incorporated similar
ordinances as part of its multi-use streets policy. County roadway construction projects
involving more than surface pavement work are required to include underground utility
conduit.

Minnesota’s Dakota County is the third largest county in the state, and has realized
significant cost and service benefits in maintaining a “Dig Once” policy. Close
partnerships between the County and municipalities since the 1980’s have been
fundamental in expanding infrastructure and delivering services. Since beginning fiber
installs in 1998, the County has connected government offices, traffic lights, schools,
parks, and many other public institutions with more than 350 miles of fiber. Estimated
cost avoidance for the County due to the conduit and existing network so far has been
over $10 million.5 And by installing conduit in trenches that are already open, they have
reduced the capital costs of connecting their communities by roughly 80%. Furthermore,
application of the policy has increased infrastructure reach into rural areas.
Reaching the County’s, roughly 400,000 citizens with broadband is expensive since two
thirds of the County is rural. Dig-once policies combined with collaborative solutions
are a key part of the County’s broadband philosophy. Expansion is guided by a strategy
of collaborative development, and cost sharing with any, and all partners. Working
relationships with local utilities, school districts, and local service providers reduce
upfront and operating costs, while joint efforts with the cities reduce cost, dilute risk,
and increase benefits. Furthermore, with shared ownership and access to this valuable
asset, local governments are now far better positioned to take advantage of future
opportunities.
State Initiatives
Another great example of “Dig Once” policy and infrastructure management can be
seen in the efforts made by the Utah Department of Transportation (UDOT). In 1999
Utah changed its state law to allow for access to the Right of Way (ROW) on Interstate
Highways. UDOT has since collaborated in many public-private-partnerships, and now
uses this newly accessible ROW for installation of conduit and fiber, to support their
Intelligent Transportation System (ITS).
Since that time, UDOT has increased its partnership portfolio, in a successful effort to
decrease capital costs for ITS projects. Private partner assets have been leveraged to take
advantage of fiber resource sharing and conduit trading opportunities. Best practices
have been integrated across the board, and include the mandatory installation of conduit
on all road construction projects, the creation of a service provider and partners list, bi-
monthly review meetings with telecom providers, and a wish list from service providers
for future joint efforts.
The State of California passed legislation in 2016 that enacts a “Dig Once” policy for the
State Department of Transportation (DOT). The DOT is required to develop guidelines
to facilitate the installation of broadband conduit on state highway rights-of-way by

January 1. 2018. The bill (AB 1549) “requires the Department of Transportation to notify
companies working on broadband deployment of Department-led highway construction
projects and authorizes those companies to coordinate with the Department on conduit
installation.” 6
Federal Government Initiatives
In 2011 and 2012, the U.S. Government Accountability Office examined proposed federal
“Dig Once” policies that would require the deployment of broadband conduit in
conjunction with federally funded highway construction projects. Their research was
meant to determine the value of such policies in decreasing deployment costs and
eliminating the need for multiple excavations.7 Their findings revealed that such policies
would likely have several advantages. Along with increasing access to, and reliability of
broadband networks, other advantages of these policies would include decreasing
construction costs, as well as the frequency of construction on major highways.
Building on this earlier work, the 2015 “Broadband Opportunity Council Report and
Recommendations” document further validated the added value of “Dig Once” policies.
The U.S. Department of Commerce and U.S. Department of Agriculture promoted “Dig
Once” policies as best practices for Local and State Governments. The report describes
“Dig Once” policies as providing important cost benefits, “by coordinating
infrastructure projects and allowing conduit to be laid alongside transportation, water
and other projects”. Additionally, they highlight that such policies “promote broadband
competition, reduce costs for broadband providers and decrease road-related costs from
repeated excavation”. 8
Other Policies to Consider
Along with comprehensive “Dig Once” policies, additional best practices include
streamlining the permitting and make-ready processes, creating policies to manage
abandoned underground facilities, redefining broadband “utility” codes and
construction standards, and managing a set aside fund to support “Dig Once” practices.
Fundamental to all the efforts detailed in this white paper, is the establishment of a
comprehensive GIS database. This resource provides real time information on current
and proposed infrastructure and capacity, and is a mission-critical tool for planning,
budgeting, and collaboration.

Streamlined Permitting & Make Ready Processes
A slow permitting process can add uncertainty in the construction timeline as well as
significant costs. Crews sit idle while waiting for permitting approvals and this adds to
the overall cost of construction. Streamlined Permitting can be implemented by using an
encroachment permit process. This can place the approval of projects solely in purview
of the public works department. Limiting this process to one department can
significantly reduce costs, miscommunication, and delays in the approval process.
Additionally, a bulk permitting process can enable a single approval for multiple
activities, further streamlining the overall process.
Dakota County Minnesota has developed an award-winning software to manage project
permitting called the One Stop Roadway Permit Shop. The system provides users with
access to twelve different permits, including utilities and rights of way permits, and
notifies them when a project of interest is being planned. 9 This system incorporates the
“Dig Once” and Shadow Conduit Policy components discussed above. It has been
tremendously successful and saves approximately $4,000 per year for each agency
involved.10
One of the most unpredictable and costly components of fiber optic construction is the
“make-ready” process. “Make-Ready” refers to the inspections, engineering, and
rearrangements necessary to accommodate the installation of multiple cables on a utility
pole. Make-ready engineering for placement of fiber optic cables needs to comply with
the National Electric Safety Code (NESC). Compliance may include moving existing fiber
optic cable, increasing the load bearing ability of poles, and/or the transfer or replacement of
existing poles required to accommodate the attachment of new cables.
At times, the make-ready process can require multiple companies to dispatch crews with
specialized equipment and bucket trucks to move their physical attachments on the
communications portion of utility poles, causing slowdowns and duplicate expense for
deployments. One-Touch Make-Ready or One Truck-Roll Procedures & Policies will
enable and encourage all work to be completed by a single company, in one service trip.
Streamlining this time-consuming and high-cost activity will save significant amounts of
time and money.
Policies for Abandoned Fiber and Conduit
Create an Abandoned Fiber and Conduit Policy to regain control of abandoned facilities.
Any abandoned fiber and/or conduit that is left vacant, and is not claimed by the owner
within a designated time period, would revert to the local government agency.
Additionally, abandoned water and sewer lines can be repurposed to house fiber and

conduit. Communities must make sure to create a process to identify, inventory and
manage potential assets.
Encourage Standards for Placement of Conduit and/or Fiber in New Developments.
The integration of broadband “utility” codes into land development policies and city
ordinances ensures uniform and standardized placement of conduit and/or fiber optic
facilities. These land development codes would require all new commercial and
residential developments to install fiber optic infrastructure. New building codes could
describe the specific and compatible communications components and architectures of
all new construction. Further, theses codes could describe the development and use of
City/County rights-of-way for communications connectivity, and could specify
standardized wiring requirements for new buildings.
Standardize Pole Attachment Rates for Placement of Aerial Fiber
Pole attachment rates vary dramatically across jurisdictions and among utility
companies. Rates are typically charged per pole per year, for attaching aerial fiber on
existing utility poles, and can range from $4 to $26 per pole. Lowering and
standardizing pole attachment rates will eliminate uncertainty and reduce operating
expenses.
Set up funding mechanisms or Set-Asides to allow for adoption of these policies.
Conduit is not expensive, but without a funding mechanism to cover installation costs,
valuable joint build and open-trench opportunities can be lost. A funding set-aside or
budget process must be put in place to allow for implementation of these policies. The
funding mechanism will allocate monies to build broadband infrastructure when
opportunities arise and the fund would maintain a reserve or set-aside for unanticipated
projects.
Keep a GIS database of all infrastructure, and provide for a process to submit plans.
Develop a policy that all construction permits issued would require the submission of
final as-built drawings. This policy would define all planning and construction
documentation requirements for utilities, developers, contractors and others in an
appropriate GIS format. Policies can then be implemented to facilitate investment from
the private sector, and can also be used to leverage assets owned by the county or
municipality. Removing roadblocks and creating efficiencies are key municipal
contributions to facilitate, encourage, and support investment.
Use of Existing Assets. Existing assets can include tower facilities, water towers, land,
rights of way, existing conduit and existing fiber. Sixty to eighty percent of a fiber optic
9
network’s capital costs are in opening a trench or in burying conduit that will house
fiber optic cable. Using existing conduit substantially reduces the capital costs of
network deployment. If a municipality has existing conduit or fiber, these assets can be
leveraged to entice further deployment of investment by the private sector. New
networks can and are built on the foundation a community’s already existing fiber
and/or conduit as well as available land.
Economic Incentives. Economic incentives as well as logistic assistance from a city can
help pave the way for more powerful broadband service. Most tax incentives are
implemented at the State-level, but the City could influence the State’s consideration of
providing tax incentives in the form of accelerated depreciation, reduced property taxes
and reduced sales taxes.
Conclusion
The good news for local governments looking to provide their constituents with next-
century broadband is that they have the power to generate revenue and mitigate costs.
By implementing “Dig Once” policies, streamlined permitting processes, and creating
“make-ready” and conduit standards, your community can lay a solid foundation for a
robust, fiber-optic, broadband network.
