1.0 Background

Over the past year, Gateway National Recreation Area staff have noted damage to existing fencing in the Staten Island locations of Gateway National Recreation Area. Removal of damaged fencing at Riis Park was added in response to concerns expressed by constituents. It was decided to combine all the repair work into one contract in the interest of expediency.

2.0 Scope

This project will provide services for the repair or replacement of existing fencing in the Fort Wadsworth and Miller Field locations and removal of damaged fencing at Riis Park in Gateway National Recreation Area.

3.0 Objectives

The objective of this project is to repair existing damaged fencing in-kind for aesthetics as well as function. In some cases, the fence damage makes it easier for the public to access unsafe areas of the parks, such as structurally unstable gun batteries. In Riis Park, fencing has been damaged by vehicles in multiple locations and is heavily rusted. For a long length of 4’ chain-link fence in Riis, the mesh was washed off in the Sandy storm surge and never replaced.

Replacements will be done as part of a future project in 2021 provided that funding is found.
