“My property includes a strip of land surrounding a retention pond. Prior to purchasing my Florida home in 1999, I obtained a written agreement from the HOA Board President to maintain this strip of land. The HOA did not believe they were obligated to do so, but agreed it was reasonable since the strip of land was too large for one landowner to maintain. Twelve year later, the HOA has informed me that they will no longer maintain the strip of land.”
Without seeing the agreement, it’s impossible to give you an opinion on whether or not you can enforce it. You need to have a local attorney review it. Also, probably the HOA documents, since it is fairly common for HOAs to be restricted in their ability to sign long-term agreements.
