The Town of Olive’s Flood Advisory Committee is undertaking a Local Flood Analysis (LFA) for the hamlet of Shokan and expanding an existing Local Flood Analysis for the hamlet of West Shokan. In addition, a stormwater analysis study will be conducted for the portions of Shokan not directly affected by river flooding. The studies began in July 2025 and will conclude within a year.
Three public meetings are planned to share study results and obtain input from residents on the locations and suspected causes of flooding. The engineering firm carrying out the LFA and supporting the town’s flood committee is SLR Consulting.
This webpage will be used to post announcements and distribute documents to the public.
Public Meetings

Public Meeting #1 – Thursday, September 11 at 6:30 pm
Save the date! The first meeting to introduce the projects to residents of Shokan and West Shokan will be held September 11 starting at 6:30 pm at the Town Meeting Hall, 50 Bostock Road, Shokan, NY. The town flood committee and SLR will give a brief overview of the LFA process and then begin gathering information from residents. Large format maps will be provided for residents to identify their properties and explain any flooding issues they have experienced. What are your experiences for flooding and stormwater? Do you have suggestions? The town and SLR want to hear from you!
Public Meeting #2 – Date to be Determined
After the first public meeting on September 11, engineers from SLR will test a range of strategies to reduce flooding for their effectiveness using engineering analysis. SLR will present the initial results at a second public meeting and again gather public input. The second public meeting will be held in West Shokan on a date to be announced.
Public Meeting #3 – Date to be Determined
By public meeting #3, engineers at SLR will have evaluated the most effective strategies offer flood reduction benefits for their feasibility, cost, and funding sources. They will present those findings to the Olive Town Board and hamlet residents at this final public meeting.
If you can’t make the public meetings
We hope you can join us in-person, but if you aren’t able to attend a public meeting you can provide input to SLR’s engineers by emailing info@ashokanstreams.org.

LFA Study Areas
Shokan – This is the first known study of flood risk in the hamlet of Shokan. Shokan recently became eligible for local flood analysis funding provided by the Ashokan Watershed Stream Management Program and NYC Department of Environmental Protection. The LFA program was developed from 2012-2014 by counties and NYC Watershed organizations in response to severe flooding in the 2010s and 2011. The Shokan study area is centered on a branch of Butternut Creek with flows fed by the slopes of Ticetonyk Mountain. The Butternut Creek runs south for about three miles from the outlet of a small pond to the Ashokan Reservoir. The creek is known to flood in several locations on Bostock Road and Red Maple Road and in low-lying areas where Black Alder Road meets Red Maple Road.

West Shokan – The town completed a Local Flood Analysis of most of the hamlet of West Shokan in 2017. In the eight years since that study, the town has implemented most of the priority recommendations. However, several areas adjacent to the original study area that were not addressed in 2017 remain prone to flooding and will be the focus of this new analysis. These areas include the lower reaches of Maltby Hollow Brook, an upstream portion of the Bush Kill above the confluence with Maltby Hollow, and an area near Lang Road fed by small tributaries that drain into the Ashokan Reservoir.
