Draft Plan Public Comment Window Now Closed 

The Howard County Department of Planning and Zoning (DPZ) greatly appreciates the many comments submitted on the draft Ellicott City Watershed Master Plan during the public comment window from July 21 to August 28, 2020. Comments received are being considered as DPZ works with its consultant team to finalize the plan. DPZ will compile all comments into a summary to be transmitted to the Planning Board and County Council this fall as part of the legislative process to adopt the master plan as a general plan amendment.

The draft master plan is a comprehensive, long-range document creates a community-driven vision for historic Ellicott City and the Tiber Branch Watershed. The plan represents the culmination of a multi-year public outreach process that began in response to the 2016 flooding and builds upon County Executive Ball’s “Ellicott City Safe and Sound” flood mitigation plan. The draft master plan establishes goals, desired outcomes and policies for the next twenty years. It also features conceptual illustrations that can serve as inspiration should specific opportunities arise over time.

Overview

Howard County launched its master plan process for Ellicott City and its watershed in 2017 with the goal of defining a comprehensive, community-driven vision for rebuilding a stronger and more resilient Ellicott City. The process has incorporated a watershed plan in a way that many traditional master plans do not. Ellicott City's unique topography, hydrology, road network, and mill town heritage will require a tailored, well-planned roadmap for long-term rebuilding. 

Our team of consultants, Department of Planning and Zoning staff, and representatives from multiple county agencies have collaborated to prepare the draft plan. The document is the result of both the project team’s technical expertise and public input collected through many events following the 2016 flood. Supporting technical material and reports associated with the planning effort are available on this webpage.

Plan Background

Plan Background at Master Plan Launch - May 31, 2017: On July 30, 2016, Ellicott City experienced devastating flooding when nearly six inches of rain fell in less than two hours. This flash flood claimed two lives, significantly damaged dozens of businesses and displaced many residents. While Ellicott City has experienced many flood events through its 250-year history, the destruction caused by the 2016 flood was the worst in recent memory.

Following the flood, the overarching goal was to return Ellicott City to normalcy as quickly and affordably as possible. During the recovery phase, Howard County effectively worked to stabilize Ellicott City and repaired and replaced damaged infrastructure; in some cases in a utilitarian fashion (i.e., asphalt was poured on damaged sidewalk areas instead of concrete or brick replacement). Merchants, business owners, residents, and many others worked tirelessly to clean up and rebuild. On November 26, these efforts culminated with an official grand reopening and ribbon cutting on Main Street. While Main Street is open, safe and functional, many rebuilding decisions have been postponed until long-term planning efforts are completed.

An engineering consultant was hired to take a fresh look at the entire Ellicott City watershed. The consultant's findings were presented at the May 31 master plan kickoff meeting, and summarized in the 2016 Ellicott City Hydrology/Hydraulic Study report (also known as the "H&H" study). The H&H study is an unprecedented, comprehensive analysis of the Tiber-Hudson watershed. The analysis modeled how certain water retention controls and channel enhancements would reduce the amount of flooding on Main Street in various storm conditions. The results of the hydrologic and hydraulic study, and the dynamic model it created, have been used as a touchstone throughout the master plan process to help guide decisions, set planning parameters, and test choices. 

Plan Background as of November 2018: The master plan was nearing its final phase - the delivery of a draft plan - when the May 27, 2018 flood hit. The draft master plan vision, which remains relevant, stated: "Ellicott City and its watershed is a model, resilient community that thrives by protecting its people, commerce, history, culture and natural environment."

Prior to May 27, the master plan process included the presentation of several draft concepts to the community. Originally, master plan concepts would be recommended as near, medium or longer-term projects. These concepts, presented in March, included a major flood conveyance improvement called "Hudson Bend," a daylit, widened, terraced stream channel spanning from Court Avenue through Lot D.

Following the May 2018 flood, it became a priority to develop an accelerated concept for flood mitigation. The master plan process was paused and the previous five-year plan for flood mitigation developed. Master plan concepts were then developed in response. However, the master plan was again paused following the 2018 election to allow for the new administration to take office. Alternative flood mitigation options were then explored under County Executive Ball's Safe and Sound plan.
