This District has received an application for a Department of the Army permit pursuant to Section 404 of the Clean Water Act (33. U.S.C. 1344) as described below:

APPLICANT:         Howard County Department of Public Works, Utility Design Division
                               Attn: Mr. Wes Daub
                               9250 Bendix Drive
                               Columbia, Maryland 21045

WATERWAY AND LOCATION:  The proposed project improvements extend approximately 29,500 linear feet along the Deep Run stream corridor from Maryland Route 100 north of Coca Cola Drive in Hanover to north of Bellows Spring Elementary School in Howard County, Ellicott City, Maryland.  The study corridor is approximately 150 feet wide, centered on the existing Deep Run Sanitary Sewer.

PROPOSED WORK:  To replace and stabilize the existing Deep Run sewer interceptor, with new pipe ranging from 12 to 30 inches in diameter.  The project will require the following temporary and permanent disturbances to aquatic resources:

  • Stabilization and temporary construction access activities will result in approximately 2,392 linear feet of temporary stream impact and 4,298 linear feet of permanent stream impact due to open trench installation and stabilization through grade control and stream bank treatments.
  • Approximately 36,381 square feet of forested and emergent wetlands are expected to be temporarily impacted due to construction access and sewer installation.
  •  Approximately 14,008 square feet of forested wetland will be temporarily cleared. Areas to remain as emergent wetlands will be restored to existing grade and seeded with native wetland seed.  A 20-foot wide corridor will be maintained over the sewer line.

Avoidance and Minimization:  The Applicant proposes to complete work within the existing Right of Way.  The proposed maintained corridor has been reduced to 20 feet in width.

Mitigation:  As mitigation the Applicant proposes to replant approximately 20,617 square feet of wetlands within the existing Right of Way.

All work will be completed in accordance with the enclosed plans dated October 10, 2018.  If you have any questions concerning this matter, please contact Ms. Jamie Larkin at 410-962-4522 or
