DEEP: Navigation Marker Permit

Navigation Marker Permit

Each permit application must satisfy certain requirements under current state regulations.  Below is a description of the criteria used under the Regulations of Connecticut State Agencies Sec.15-121-A5 to review and approve navigation marker permits. Each criteria is listed with further clarifications italicized.

R.C.S.A. Sec.15-121-A5 Permission to place markers.
(e) Criteria for authorization shall include:

  • Signed approval from the Chief Executive Authority (CEA) of the town or designated lake authority in which said marker will be placed; The CEA must be the 1st Selectman, Town Manager, Mayor, or designated Lake Authority Chairman or official.

  • Completeness, accuracy and detail of the application form; The application must be accompanied by an assessor’s map or navigational chart with latitudes and longitudes, or bearings and distances to clearly defined shore objects.

  • Demonstrated need for the proposed markers; In addition to statements, evidence including photos and reports are desired. 

  • Public safety considerations;  The effect on waterway traffic flow and boat maneuverability are analyzed during the site inspection.  Unreasonable restrictions on boating activities are unacceptable.

  • Environmental impact considerations; The surrounding shoreline and bottom are considered from the perspective of erosion, vegetation and sediment disturbance when assessing the effects of a proposed permitted area.

  • Review of possible conflicts with various water use groups.

  • Visibility and durability of proposed markers; These requirements are standardized in our permit guidelines as authorized under paragraph (f) of this section and also in accordance with RCSA Sec. 15-121-A2.

  • Conformity with existing authorizations; Any new permit must not conflict with or lessen the effectiveness of other permits. 

  • Consistency with federal, state and local law.  Self-explanatory.
