After a long season of activities, our Park lawns will be closed for lawn restoration on September 23, 2019. Each lawn will be aerated, a process in which small cores are pulled from the soil. By removing these cores, the soil is able to better absorb water, take in air, and reduce the compaction caused by the thousands of people who have enjoyed the lawns this past summer. Cool night temperatures during the fall are best at establishing healthy root systems. Each lawn is then reseeded and fertilized to prepare lush grass for next spring.
You may have noticed that it has rained quite a bit this season. Madison Square Park received 20% more rain between January and June than average. Many of these rainfall events resulted in heavy downpours. We all enjoy a sunny day on the Oval Lawn, but our lawns are also an important piece of green infrastructure, capturing rain runoff during downpours that would otherwise go into our sewer systems. During heavy rainstorms, combined sewers receive higher than normal flows in which NYC’s water treatment plants cannot accommodate. When this occurs, a mix of stormwater and untreated sewage discharges directly into the City’s waterways. Healthy lawns help absorb water runoff and keep our sewer systems running properly.
We appreciate your cooperation during these closures and your assistance in helping to keep our lawns healthy and our waterways clear. We anticipate our lawns to be open again in May 2020 for daily use.
