More communities now embrace "dig once" policies to facilitate installation of future and current networks. The idea is to be mindful of trenching for transportation and utility projects and encourage collaboration between agencies. However, this is implemented in a variety of ways, some more effectively than others. By establishing requirements for conduit installation in development codes, communities can save big dollars if they build or expand a network in the future.

Communities such as Sandy, Oregon, and Mount Vernon, Washington, have instituted such policies. Both communities require private developers to install conduit when disturbing existing roads or building roads for new subdivision construction. Conduit itself is inexpensive and the digging is already done, so the added burden is light.

Both of these communities have plans, including maps, that allow them to be strategic in where they require conduit to be placed. They are not simply adding conduit blindly, though that policy may be better than doing nothing at all (experts are divided on the matter).

In Sandy, the code change (see Sec. 17.84.60) was a simple expansion of existing policy. The city added "broadband (fiber)" to the list of public facilities, such as public water, sanitary sewer, and storm drainage. Underground communication lines join a list of other required improvements that are to be installed in new developments at no expense to the city. Other items on that list include drainage facilities, mailbox delivery units, street lights and a underground power lines. (see Sec. 17.100.310).
