96% of US adults own a cell phone. In the past eight years the number of people owning smart phones has grown from 35% to 81%. With this increased reliance on mobile connectivity comes the need for increased capacity in cellular networks. Wireless carriers are meeting this need by supplementing their macro cell sites (towers) with antennas referred to as "small cell technology". 'Small cells' are lower power antennas that cover smaller geographic areas to target where more network capacity is needed.

Proposed Design Standards for Small Wireless Facilities (SWF)   

The Seattle Department of Transportation (SDOT) has published SDOT's proposed Director's Rule on Design Standards for Small Wireless Facilities (SWF) attached to public and private poles within City of Seattle right-of-way. These standards are being proposed in order to reduce visual impacts to the streets and sidewalks that form the public right-of-way by establishing rules concerning SWF design. SDOT has completed an environmental review and issued a SEPA* Threshold Determination of Non-Significance (DNS) for this non-project proposed rule.

You can read the proposed SWF design standards here, which include diagrams and photos to help visualize these installations. You can review the SEPA Threshold Determination of Non-Significance (DNS) here, as well as the SEPA Checklist.  

If you have comments on the proposed design standards and the associated SEPA DNS, the public comment period runs for two weeks from February 13, 2020 and closes on February 27, 2020 at 5pm. Comments may be submitted online, by email at, or by mail to: Seattle Dept of Transportation, Attn: A. Nelson, PO Box 34996, Seattle, WA 98124
