Staff's PWDG Plan has the Manassas National Battlefield Park "covered". The existing data center opportunity zone overlay district (DCOZOD) does not.
The National Park Service's 9/19/2022 Comment Letter on the PWDG Plan Amendment states:
"The PW Digital Gateway Draft dated August 15, 2022, although not a perfect proposal, encourages mitigations to reduce viewshed impacts, and recommends the preservation of historic structures, landscapes and cemeteries. The Plan establishes preservation easements for key Battlefield lands..."
Staff's PWDG Plan recommends the following:
Screening techniques such as berming, planting trees, and preservation of existing tree canopies be employed in areas where there are viewshed impacts from Manassas National Battlefield Park.
Building heights for individual data centers: established based on existing and/or proposed topography, tree cover and vegetation (informed by detailed viewshed studies performed with each site-specific zoning review).
Height limitations to protect specific viewsheds be evaluated during rezoning, using LIDAR (Light Detection and Ranging) technology-assisted line-of-sight analyses, drone vertical horizon visual testing, Augmented Reality, massive digital imaging, or other similar techniques and technologies.
The DCOZOD zoning regulations do not limit or otherwise address the height of data centers, even though they are visible to the Manassas National Battlefield Park from sites along Ball Ford Road.
The DCOZOD requires only non-reflective earth tone colors and cosmetic façade treatments.
