Riverdale seeks qualified consultants to conduct a vegetation study in 2020

(Update 09/24/19) – The City of Riverdale has issued an RFP (Request for Proposal) from a qualified arborist or vegetation consultant to conduct a study of invasive species in the City’s parks and wild spaces during calendar year 2020.

The City Council approved RESOLUTION 2019-37, which authorized the publication and distribution of the RFP to qualified vendors/consultants. The budget for the project was set at $10,000. Earlier this year, the City set aside up to $20,000 to study the invasive species problem in Riverdale and deal with it accordingly.

A copy of the RFP can be found here. The study is expected to be conducted in the areas indicated as “Active Parks” and “Vacant” areas on the map.

An initial meeting of the City’s Invasive Plant Task Force has been called for Friday, August 3rd at 11am. The meeting will be in Council Chambers at City Hall.

Those present will discuss the on-going problem posed by invasive plant species in Riverdale’s parks, yards, gardens and wilderness areas and the economic costs of allowing these species continue to grow and choke out ground cover on the City’s hillsides and other green spaces.

City Council member Kelly Krell will lead the discussion and chair the meeting.

The meeting is open to the public.

We want you to help us fight the oncoming invasion!

We want you to help us fight the oncoming invasion!

No, this isn’t a warning about pod people or Martians.

But the City of Riverdale is facing an unprecedented invasion and it’s up to all of us to deal with it.

The City is beginning the process of studying and addressing the invasive plant problem in our parks, yards and other green spaces. Species like Garlic Mustard (pictured below) are choking out native plants that provide ground cover and keep our soil from eroding off hillsides, etc.

Already this year, the City has spent over $15,000 to repair an eroded hillside. Imagine how much we might have to spend if this problem goes un-checked and we end up losing larger and larger swathes of growth of underbrush? By studying this problem now and exploring our options, we can avoid a potentially crippling infrastructure problem.

That’s why I formed the Invasive Plant Task Force and asked Council Member Kelly Krell to chair it. I urge any residents who might be interested in participating in the broader public conversation to attend the task force’s first meeting on August 3rd.

The group will study the problem, explore possible solutions and make a recommendation to City Council on what to do (if any action is required). Assuming we do SOMETHING, this group will also help coordinate the actions of the City, its residents and interested/affected businesses.

Your participation is greatly appreciated. Your voice will be heard.
