PRE-SOLICITATION NOTICE:

The National Park Service, CONOPS – Central, intends to issue an Invitation for Bid (IFB) for the Entry Courtyard Improvements project at Brown V Board of Education National Historic the Dayton Aviation Heritage National Historic Park in Topeka, KS.

Existing signs will be relocated to concrete viewing areas on NPS property, rather than being within the city’s ROW. The site will be graded so the existing low point where storm water currently pools will be relocated to the turf grass lawn area with drainage directed into an aggregate storage chamber.
