Local Engineering Context

Authority Having Jurisdiction: City of Alexandria Department of Transportation & Environmental Services / Department of Planning & Zoning
Building Code: 2021 Virginia Construction Code (2018 IBC with Virginia amendments) with City of Alexandria amendments
Energy Code: N/A
Local Market: National Landing (the branded development zone spanning parts of Alexandria and Arlington anchored by Amazon HQ2) is generating major civil engineering demand — large mixed-use sites, underground parking, streetscape improvements, and utility extensions in an environment with active WMATA infrastructure beneath many parcels. Old Town's historic grid simultaneously produces a steady stream of infill and adaptive reuse civil scopes requiring careful coordination with Alexandria's Heritage Resource staff.
Climate & Engineering Conditions: Zone 4A mixed-humid; Potomac River proximity creates flood zone constraints for Old Town Waterfront and low-lying parcels; annual rainfall of ~40 inches and Chesapeake Bay watershed designation require Virginia DEQ-compliant stormwater management for virtually all disturbed-area thresholds; impervious cover limits apply in many zoning overlay districts.
