Engineering report: Manassas advances stormwater retrofits, creek restorations and sidewalk projects
Summary
City engineers described a portfolio of stormwater and transportation projects under design or construction, including creek restorations near Liberia House, pond retrofits and a citywide CCTV program to inventory storm sewer assets.
Manassas engineering staff told the City Council on Jan. 27 that the department is managing roughly $120 million in construction and has multiple stormwater, drainage and pedestrian projects underway.
Engineering Director Lance Kilby and staff highlighted completed and in‑progress projects including the Great Branch and Lucasville pond retrofits, the public‑works pond retrofit, and mobilization for the Wellington Road shared‑use path and the Sudley Road third lane project. Kilby said the department had recently taken over an excavation permit program to oversee fiber and utility trenches and to ensure roads are properly restored.
Why it matters: Improved stormwater infrastructure reduces flooding risk, improves water quality and meets state MS4 requirements. Several projects also involve right‑of‑way acquisition and require coordination with VDOT and private property owners.
Key details - Liberia stream restoration: Staff said the rehabilitation will replant roughly 600 small trees/shrubs and about 120 larger trees, restore trails and rebuild a temporary Boy Scout bridge; Department of Historic Resources coordination was noted because of nearby historic structures (including the Spring House). Engineering said the project uses natural channel design techniques. - CCTV and asset management: The city launched a CCTV inspection program funded with ARPA dollars and implemented the Cartograph asset‑management system to inventory storm sewer condition citywide. - Timeline and coordination: Multiple sidewalk, roundabout and right‑of‑way projects are in 60–90% design; Sudley Road sidewalk work requires acquisition of roughly 29 parcels and will be a longer process. Centerville roundabout is at 90% design; right‑of‑way acquisition involves seven parcels.
Public questions and context Council members asked about public visibility and protections for historic sites near restoration work; engineering staff said stream work had been coordinated with Parks, Culture & Recreation and the Department of Historic Resources and that a structural review of the nearby Spring House is planned. Staff also said some culverts in the city have reached the end of their useful life and emergency repairs—such as the Shannon Lane culvert—were completed in 2024.
Ending Engineering asked for continued patience during construction windows and reiterated that many projects are tied to state and federal funding and require parcel acquisitions or utility coordination before final construction can proceed.
