You can make a difference in the future of Greenwood Lake. Here's how:


  • Volunteer with us
  • Attend monthly Commission meetings on the fourth Wednesday of every month
  • Contact your local, county, state, and federal legislatures to support ongoing efforts of the Commission
  • Limit use of fertilizers and pesticides (only non-phosphorus fertilizers are permitted)
  • Use and dispose hazardous products properly
  • Do not pollute storm drains
  • Clean up after your pet
  • Don't feed wildlife
  • Pump out septics
  • Replace foam dock floats with rigid plastic floats
  • Don't litter
  • Dispose all waste properly


  • Speed limit: 45MPH from dawn to dusk / 15MPH from dusk to dawn
  • Permits are required for replacing and/or building a new bulk head and/or boat house
  • Permits are available from NJ DEP and NY DEC for use of herbicides


  • Retaining walls, seawalls, bulkheads, etc. would be considered an improvement to a single family dwelling, and are eligible for a Highlands Rules "in-house" exemption under 7:38-2.4(b)1.  "In-house" means you don't have to apply for a formal Highlands exemption. This "in-house" exemption is valid, so long as it pertains to a single family dwelling lawfully in existence on August 10, 2004 or prior, and provided the lot upon which the home is situated has  not been further subdivided since August 10, 2004.  All other property owners (such as commercial marinas) must apply for, and receive, a formal Highlands exemption, NJAC 7:38-2.3(a)4.  West Milford is authorized to issue these latter exemptions.
  • There any number of Freshwater Wetlands permits that may/may not be required, depending on each particular situation of what the land owner would like to do.  These may include General Permit Nos. 1, 13, 19, 20, and 26 or in some cases an Individual Permit.  In some situations, a Freshwater Permit is not required.  There are many scenarios with near and in-water situations, and sometimes there is no easy answer on whether permits are required. The NJDEP should be contacted for guidance on your individual circumstance. 
  • Under the Flood Hazard Rules, what permits may/may not be required also depends on the particular situation, no easy answer.  However, if needed, available permits are Permit-By-Rule and Individual Permit. Again, call the NJDEP for guidance. 
  • Due to its being an interstate water, Greenwood Lake is a non-assumed water; therefore, in addition to any required DEP permits, property owners must apply to and receive a Nationwide Permit from USACOE.
