High Ground Access Points
Public safety is the top priority of the Ball Administration, not only in Ellicott City but across Howard County. That is why the Ball Administration is moving forward with flood mitigation projects that will take significant amounts of water off of Main Street during severe weather events. However, it is still important to have tools available that can help people to safety when severe weather strikes. The outdoor tone alert system, along with the existing wireless emergency alert system, stream monitoring devices, and other communications channels are part of a comprehensive system working together to protect public safety.
The National Weather Service advises that when flooding occurs, the best thing to do is exit the floodplain if it is safe to do so. The High Ground Access Points, detailed on the map below are meant to show ways to exit the floodplain at different points on Main Street. It is important to note that due to the unpredictable nature of floods, some routes may be impassable.
In 2019, "High Ground" signs were placed along Main Street identifying routes out of the floodplain. In each parking lot in Old Ellicott City, informational signs were installed explaining the access points. The Ball Administration also be provided signs, table tents, and window clings that businesses can display to provide this important information to their customers.
Private Access Point Gates
In addition to the High Ground Access Points, the County has agreements with two property owners in Historic Ellicott City (8044 and 8060 Main Street) on private property that allow people to quickly get off Main Street in the event of a severe weather emergency. Each point has a staircase that leads to a space above Main Street where people can wait out severe weather more safely. These two gates remain secured during non-emergency times but will automatically open in the event of high-water and/or the issuance of a Flash Flood Warning in Historic Ellicott City.
The gates can be opened by the County’s public safety team remotely and on-site. Additionally, the gates are equipped with high water sensors, and a pin code can be used to unlock the gates if needed. Community members and visitors are advised to call 9-1-1 to request the pin code if they need to seek higher ground, and the gates are locked.

Frequently Asked Questions
Why do we need the Safe and Sound Stream Debris Removal Program?Areas that experience flooding during major rain events may benefit from the removal of debris in nearby streams. Excess stream debris can cause localized flooding when constriction points along the stream become blocked by debris and cause a backup of water onto roads and other infrastructure. The most common constriction points are the undersides of bridges and culvert openings. Culverts are the pipes and concrete structures that carry streams under roads. When these blockages occur, the resulting flooding can create a threat to human safety, personal property, public infrastructure, and the environment. Stream Corridor Assessments completed by S & S Planning and Design after the 2011 and 2016 floods in Ellicott City documented debris blockages as contributors to flooding and recommended that a debris management program be instituted. Channel maintenance for debris has been ongoing on the Hudson Branch in Ellicott City since 2015 and is now being expanded in both geography and frequency. To minimize the risks associated with stream debris, Howard County is sending Howard EcoWorks into nine flood-prone streams after qualifying weather events to assess for accumulation of debris, determine what is appropriate to remove, and then remove debris that has the potential to contribute to localized flooding.
What is stream debris?In this context, stream debris is anything within the stream or immediately along its banks that threatens to move downstream during high flow events and has the potential to clog culverts or other constriction points, which can result in local flooding. This may include logs, branches, trash and/or other bulk material.
Where is stream debris being removed?Debris is being assessed, and removed if needed, at dozens of sites on public properties and on Columbia Association property along nine Howard County streams. These sites have been chosen because they are locations that are known to experience, or contribute to, localized flooding.
What if I see debris that could create a blockage in an area not covered by this program?Please report such debris using the County’s “See, Click, Fix” application, linked here: https://en.seeclickfix.com/md_howard-county
When is the debris removed?Debris will be removed after any rain event of 2” or greater accumulation in a 24-hour period, or after an hour of sustained winds over 30mph. Within three business days of a qualifying wind or rain event, each of the locations will be inspected for accumulation of debris and need for removal. Within fourteen business days of the inspection, the material that was identified for removal during the inspection will be removed.
Who is identifying and removing the debris?Debris will be identified and removed by Howard EcoWorks or the County Bureau of Highways.
Why don’t inspection crews remove debris immediately after identifying an accumulation?Inspection results are analyzed before removing material because some locations may have a more immediate need for removal than others, based on stream conditions, threat to property or infrastructure and weather forecasts.
Why are the results reported as “cubic yards of debris removed”?While weight of debris could be used to track this effort, volume (the space that an object occupies) is what really causes backups at constriction points such as culverts and bridges. For example, while millions of tiny steel ball bearings may weigh more than all the woody debris removed from a stream, they would not cause as severe of a backup as less dense, but larger, woody debris. A cubic yard can be visualized by picturing a cube that is 3 feet long, by 3 feet wide, by 3 feet deep. The bed of an average full size pickup truck, full but not piled higher than the edges of the bed, will hold 2.5 cubic yards of material.
Why has the debris been left as a pile along the side of the road?The County or Howard EcoWorks may need to temporarily stage debris along the side of the stream or road for later pickup due to vehicle availability and amount of debris. These piles will be removed within the fourteen business day timeframe that begins immediately following a significant wind or rain event. Click here to review a flow chart of the stream debris removal process.
Why is debris being removed only from public property and CA property?To begin this process as quickly as possible, public properties have been selected because access to private property relies on the permission of private landowners which often takes several months for the County to acquire. Pre-existing agreements between Columbia Association and Howard County provide the County with access to Columbia Association’s private parcels, without necessitating the process of acquiring permission to enter individual parcels.
How will the County and Howard EcoWorks determine what debris to remove?Priority debris for removal includes 1) debris within and immediately upstream of culverts or other areas of constriction, 2) debris that has the potential to mobilize during an event and create a blockage downstream and 3) debris that otherwise poses or may pose a risk to adjacent infrastructure. Debris is typically composed of fallen trees and logs and may also contain smaller branches, overhanging branches and vines and trash / bulk material. Consideration for removal is given to the size of the debris relative to downstream constrictions, potential for the material to mobilize or create a hazard during a storm event and the location of the debris in stream bed or on the stream bank. The area of inspection is up to approximately bankfull elevation. The bankfull elevation is the same as the ordinary high water mark (OHWM); in many channels this is the point where water begins to flow out onto its floodplain. If stream banks are armored, live, overhanging branches <3” in diameter will be removed. If stream banks are unarmored, trees and limbs <12” in diameter will be removed if they are considered priority as defined above.
