Changes

The area of Broomall’s Lake has resettled and is now a meadow with a free-flowing stream running through it. We have observed deer grazing as well as other wildlife. Due to the lack of rain as well as the change in hydrology, Broomall’s Run, as it passes through Glen Providence Park, appears to have a much lower flow. A great deal of sediment from the lake has also been deposited in the stream and probably in the pond. We are watching closely and consulting with experts to learn about the short and long term impacts on the stream and the pond. 

Construction

To the best of our knowledge, plans for construction of the dam and two way road continue with Media Borough as the project manager and is slated to begin in late 2018. We are not aware of either Delaware County or Broomall’s Lake Country Club (BLCC) agreeing to be owner — a requirement for DEP permit. Friends of Glen Providence Park continues to advocate for full stream restoration and an environmentally sensitive bridge across Broomall’s Run that addresses the community’s transportation needs. 

Zoning & BLCC Development

Media Borough has begun the process of changing the zoning of a few parcels in town to MERC (Municipal, Educational, Recreational, Community) and one under consideration is the BLCC property. This property has been used recreationally for nearly 100 years as a private swim club, and is one of the only remaining large tracts of undeveloped land in Media Borough. Delaware County’s Open Space Plan of 2015 encourages municipalities to “take full advantage of their planning and zoning powers to protect sites and land resources of community importance.” (Open Space and Recreational Plan, Vol. 1, Chapter 3, p. 29; Delaware County Planning Department, 2015.)

BLCC leadership is strongly opposed to this zoning change, expressing their desire to retain the right to develop their land, which they estimate to be worth more than 12 million dollars if developed into 17 townhouses, as stated in their attorney’s letter to Media Borough dated September 29, 2017. Many club members who attended a Borough Workshop meeting expressed surprise at the club’s opposition to preserving this historic tract of land. 

A group has emerged in support of preserving open space in Media called Keep Media Green. Friends of Glen Providence Park supports the preservation of the BLCC property as open space. It will protect the vulnerable Ridley Creek Watershed, of which Broomall’s Run is a part, will help keep storm runoff and flooding more manageable within the park, and will help to mitigate the effects of development all around Glen Providence Park and Media Borough. You can find Keep Media Green on Facebook. 

Footbridge

Friends of Glen Providence Park continues to work with a community coalition that has made proposals to, and met with, Delaware County Council about a way to establish a pedestrian footbridge at the partially removed dam — we expect to have an update soon.

Partial breach of Broomall’s Dam when it was completed in July

On February 22, about 100-150 people crowded into the Media Borough Parlor Room to meet with officials from the PA Department of Environmental Protection (DEP) to discuss the planned partial breach of Broomall’s dam in late April.

After some time to look over the technical plans and respond to residents’ questions, the DEP presented the why’s and how’s of the removal of Broomall’s Dam for safety reasons. Roger Adams, Division Chief of Dam Safety, gave a compelling presentation of the dangers to human life and property when a dam fails. Examples include the Bayless Dam, in which 10” of rain caused a catastrophic failure.

High hazard dam in poor condition

Of the 3,371 dams in Pennsylvania, only 754 are high hazard dams. While Broomall’s Dam is smaller than large dams like the Youngstown Dam, it is still categorized as a High Hazard C-2 dam, based on the amount of water and sediment held back and the height. It is also a High Hazard dam in poor condition. Even if the dam is rebuilt, it will again be a High Hazard C-2 dam.

Broomall’s an orphan dam that is deteriorating

Duke Adams (no relation to Roger), took up the presentation and discussed the issues around ownership. The dam was built in 1883 by John Broomall for ice harvesting. In 1980 the Army Corps of Engineers found the dam to be structurally in poor condition. In 1996 the roadway was closed for safety reasons. No party, not Broomall’s Lake Country Club (BLCC), Media Borough or Delaware County have been willing to take up the maintenance responsibilities over this time. The DEP has considered Broomall’s Dam an “orphan dam” because of the lack of responsible or willing owner.

In June 2014, Delaware County, BLCC and Media Borough signed a stipulation and order. Duke Adams explained that this order means that Media Borough would manage the reconstruction of the dam, and Delaware County would take ownership of the downstream face, and BLCC would be the owner and responsible party for the upstream face.

In 2012, BLCC sued Media Borough over its plan for a one-lane compromise for the bridge  — a solution that was supported by borough residents, Friends of Glen Providence Park, and the majority of Borough Council. Shortly thereafter the dam began to deteriorate significantly, with entire pieces of wall crumbling on the upstream and downstream side. The DEP elected to lower the water level to its absolute minimum in June 2013, and when the lake level was not maintained, the DEP returned and lowered it again in March 2016.

Eliminate the hazard

However, due to continual delays and a lack of clarity of an owner (none of the three parties has stepped forward and take responsibility to date), the DEP has decided to eliminate the hazard of the dam. By removing nearly all of the standing water and a significant amount of liquid sediment, the pressure on the dam walls will be reduced. The hazard category will be lowered to C-4.  Their presentation highlighted the dangers of allowing high hazard dams to remain in place.

Work begins in early May

The work on the dam will begin around May 9th and should conclude within two months. During construction, the entire corner of 3rd and West Street will be closed to all traffic and the entrance to BLCC swim club will be closed, to reopen once the partial breach is complete.

The main spillway of the dam will be removed, as will the waterfall. Broomall’s Lake will drain almost completely and construction access into the lake will remain until the dam is reconstructed. The original stream of Broomall’s Run will find its own course and several springs that feed into Broomall’s Lake may make their appearance.

The DEP reported that before dam removal begins, up to two weeks will be spent to remove the PA Threatened Northern Redbelly Turtle (Pseudemys rubriventris) and native snapping turtles, which will be relocated to the pond in Glen Providence Park. The invasive Red-eared slider (a similar looking turtle) will be removed and donated to science programs. Other fish, frogs and invertebrates will have to find their way during the draining of the lake or they will perish. Traps to capture turtles were set on April 24th. 

Loss of pedestrian and bicycle access for Upper Providence for 2 years or more

The likely reason why so many people came to the meeting was due to the disruption of pedestrian and bicycle access across the dam starting at the end of April, and lasting until the proposed dam reconstruction. Roger Adams could not say how long the period between dam removal and dam reconstruction would be, but did not hesitate to say at least two years. (The dam reconstruction permit has not been approved or scheduled to date.)

There were a number of questions from the audience on the issue, particularly focused on Upper Providence residents who use Third Street frequently to walk into Media. Safety issues were also raised by residents, particularly the concern that if there were no access at all, some daring individuals would somehow find a way that would most likely be very unsafe. The DEP indicated that there might be a possibility of installing a temporary pedestrian bridge.

Stream Restoration

A benefit of dam removal is the re-establishment of open waterways and natural streams. Artificial dammed bodies of water not only present a hazard of failure on the downstream side, but they also hold back aquatic life and sediment that contribute to the overall health of our waterways. 

Pedestrian Bridge

A coalition of Upper Providence and Media neighbors and Friends of Glen Providence Park is working to establish a temporary pedestrian footbridge to maintain the connection between Media and Upper Providence in the time period between dam removal and dam reconstruction. The proposed footbridge is modular and can be relocated into Glen Providence Park at one of the former bridge sites once dam reconstruction begins. If you are interested in supporting this effort, please contact us.

On Wednesday, February 22 at 6pm, at the Media Borough Parlor Room, area residents will have an opportunity to hear from the PA Department of Environmental Protection (DEP) in a Public Informational Meeting about the planned partial breach of Broomall’s Dam, currently scheduled for April 30th.

The partial breach will reduce the safety hazard of the orphaned dam which is in severe disrepair.

However, the partial breach will render the road impassable to pedestrians and bicycles in addition to cars for two years or more, until the proposed dam reconstruction is complete. With no parties yet willing to claim ownership of the current or proposed dam, it is uncertain how long this pre-construction phase will last.

Temporary Pedestrian Bridge?

Friends of Glen Providence Park has requested Media Borough Council to consider the construction of a temporary pedestrian bridge during this pre-construction phase. We feel it is in the best interest of Media Borough and Upper Providence to maintain this connection.

Why maintain the connection:

• Safety: We are concerned that people will attempt to find a way to cross the breach that is unsafe.
• Economics: Many people walk to Media for shopping and great events like Dining Under the Stars. Some people commute to work from UP to Media on foot — across Broomall’s Dam on 3rd Street!
• Community: 3rd Street is a valuable connection between Upper Providence and Media neighbors and activities.
• Best Practices: It is a PennDOT recommendation in their Design Manual to continue pedestrian access during construction (Chapter 6.14, Pedestrian Facilities and the Americans with Disabilities Act, 2012.).
• Time: 2-3 years is a long time to have this connection broken.

If you’d like to see a temporary pedestrian bridge, please come to the meeting and make your voice heard.

In addition, it is our understanding that the 3rd Street entrance to the park will be closed while the DEP is removing the dam, which is expected to take about 60 days.

Friends of Glen Providence Park continues to support dam removal and stream restoration with an environmentally sensitive connection between Upper Providence and Media, which will minimize damage to the park. 

Third Street Dam Safety Workshop

Monday, August 20, 4:30-6:00 p.m.

At the dam site

Is the dam safe for now?

We encourage park users, those who live downstream and schools and community groups who use the park to attend and learn about how the dam operates, why the dam has been deemed unsafe, and what measures are or should be in place to protect people downstream in the event of an emergency. Mr. Reisinger will discuss dam basics as well as an evaluation of the current dam’s safety, and what measures citizens and those downstream can take to ensure their own personal safety. He will discuss the requirements for an Emergency Action Plan (EAP). The Third Street Dam is a high hazard dam in poor condition. After reconstruction it will continue to be a high hazard dam due to its potential impacts on human life in the case of failure.

Delaware County, BLCC and Media Borough invited to attend

Media Borough Engineer Bob Johnston will attend, and at this time no other officials or BLCC leadership have responded. Currently Broomall’s Lake Country Club operates the dam, and it is presumed that they will continue to be the operators. Delaware County and Broomall’s Lake Country Club, according to the stipulation, will be sharing responsibility for the dam after reconstruction;  Media Borough will maintain the roadway atop the dam.

Bring Questions

There will be ample time for questions and answers, and we are thankful to Mr. Reisinger for taking the time to educate our community about the state of the Third Street Dam.

Friends of Glen Providence Park, after carefully doing research and weighing the evidence, has decided to fully support dam removal and stream restoration as the most promising option for the resolution of the 3rd Street Project. But the question on everyone’s mind seems to be:

What would Broomall’s Lake look like if it became Broomall’s Run again?

Look upstream, look downstream. You see a babbling brook, a creek, surrounded by woods and rocks. There are some wetlands, which are precious birthing grounds for turtles, frogs and fish. You see trees such as Sycamore, Tulip Poplar, American Beech, Oaks and Maples. You see shrubs like Witch Hazel and Spicebush. (Yes, there are some invasives…more on that later.) Some experts think that there are some natural waterfalls, undoubtedly smaller than the man-made one, because of the significant drop at the dam. Apparently, pre-dam, the same area was where people forded the creek, hinting that there may be bedrock beneath the dam somewhere.

Contrary to common belief, dam removal and stream restoration does not ultimately result in horrible mud flats and mosquitos. Nature finds equilibrium and sediment runs downstream while plants get seeded. With some help from restoration experts, some tree planting and perhaps some earth moving, things return to a “new normal.” In fact, it’s more like the “old normal,” before the dam was built.

Going with nature, by removing the dam and restoring the stream, will save a great deal of money and effort. When humans go against nature, it’s always costly. Right now, Broomall’s Lake needs expensive dredging because it is filling up with sediment. Why is it filling up with sediment? Because there is not supposed to be a lake or dam.

And what about that sediment? According to American Rivers regional experts, sediment in Pennsylvania’s old dams is rarely dangerously toxic, though it’s not spa-worthy mud.

And the State of Pennsylvania and American Rivers both know a thing or two about dam removal, stream restoration and management of sediments. Pennsylvania is the country’s leader in dam removal, probably because we are a large old state with a lot of old, old dams. American Rivers has been assisting public and private entities to clean up their waterways across the country. If you think Broomall’s Dam is a big project, look at the recent removal of Elwha Dam.
