Smart Growth Protects What We Have: A discussion on Data Centers from the Rural Crescent to the Occoquan Reservoir
Thursday, January 6 at 7:0pm.
Landowners on Pageland Lane have filed a data center development proposal covering more than 2,000 acres next to Manassas National Battlefield Park and Conway Robinson State Forest. Although the plan appears to focus on data centers, it also opens the door to other industrial uses, such as warehouses, that generate truck traffic and the need for a major new road connecting I-66 with the back side of Dulles Airport (Bi-County Parkway).

OBNWRQuarantine at the Occoquan Bay National Wildlife Refuge with Kelley Studholme
Green open space close to home has never been more important.

I love the Spring just before total leaf out, here in Prince William County. We are so fortunate to live in a place near the Occoquan River, Belmont Bay, Occoquan Bay and Potomac River; all of which are tidal, causing a constant ebb and flow of the water and wetland areas. Each day is new and different offering migrating birds and ducks and other water fowl, not to mention the many plants, reptiles, and animals.

Due to the quarantine, I have limited my time outdoors to only a few locations in the area to observe wildlife and get a little exercise. Lately, Occoquan Bay Wildlife Refuge (OBWR) has been my go to place to enjoy nature. My back yard also works but I don't get as much exercise there. Read more...

The diversity of habitat at Silver Lake is an important contributing factor that explains the large variety of birds that can be found there. Once on a Christmas Bird Count, it was so cold that the quarry was one of the only unfrozen bodies of water in the entire count circle. The number and variety of ducks that sought refuge there that year was amazing, read more...
