Multiple Vessel Mooring System -
Ad Hoc Committee Pilot Program Evaluation
Final Report
City Council Study Session
June 10, 2014
Background
"Multiple Vessel Mooring System" (MVMS) currently
allowed per NBMC 17.60.040 (13)(1)(c) & 17.01.030 0)(15) in
the single -point mooring fields onlX (e.g. NHYC and BYC fields)
Pilot Program Evaluation
- - - -- - ----- - ------- - ----------------
- ------
► February 2014:
Mayor Hill tasked the Harbor Commission to:
Study the MVMS in the double -point mooring areas; and
Return to Council with a recommended pilot program
Purpose of the Pilot Program:
Provide amenities to the mooring community by providing an easier
way to moor a vessel
Decrease the mooring field footprint, therefore increasing usable
water area
Provide a convenient load /unload point for a water taxi system

► Newport Mooring Association Outreach (discussed later)
Ad -Hoc Committee Findings
► No pilings
Too "permanent" for pilot project (does not allow for adjustment)
Possible view issue
► Work/Wash -Down Float (NMA suggestion)
► Legal Concerns with City Owned Dock? (liability)
► No Electricity/ No Water
Too complex for pilot program
Must be buried at least 5' below sediment surface (Corps requirement)
Proximity to street -end required for utilities
Possible future option
►
Ad -Hoc Committee Findings cont'd
Possible Mooring Locations for
MVMS
Existing permittees volunteer for
pilot project
No charge for floats
Permittees continue paying normal
annual mooring permit fee
Permittee's mooring equipment
stored out of water
► C Field (City owned moorings for visiting boaters)
► D Field (Proximity to Harbor Resources)
► H & J Fields (Large field, high visibility)
Ad -Hoc Committee Findings cont'd

Anchor options:
Existing buoy, weight & chain method
Helix anchor & elastic band method
Hybrid (weight + bands)
Floating Dock with Buoy, Weight 8, Chain Method

Community Surveys
Newport Mooring Association Survey Results (web)
"Do you want floating docks ?"
61 responses
85% negative
"Would you volunteer your mooring for a pilot program ?"
54 responses
I "yes"
"What are the top priorities for mooring permittees ?"
39 responses
Top Priority: Shore -side work dock (charge batteries, overnight, light
mechanic work etc...)
Community Surveys (cont'd)
► City Survey
No survey performed yet (short study period)
Options:
Survey prior to pilot study
Survey during pilot program after floats are installed

Conclusions &v Recommendations
Implement Pilot Program for at least 2 summers
Install 6 floats (or more ... or less per Council direction)
40'— 50' long
6' wide

fiberglass, aluminum etc...)
