10a. Update on water jet skis A CITYOF .-- 1 .. CHANHASSEN 690 COULTER DRIVE • P.O. BOX 147 • CHANHASSEN, MINNESOTA 55317 1 *P.' (612) 937-1900• FAX (612) 937-5739 1 MEMORANDUM 1 TO: Mayor and City Council FROM: Don Ashworth, City Manager 1:wptik.., DATE: July 23, 1990 SUBJ: Update on Water Ski Jets 1 In early July, Councilmember Jay Johnson requested staff to provide 1 an update regarding the water ski jet ordinance. He also requested information regarding registration and licensing requirements. Following that date, we did receive a petition from homeowners on Lotus Lake. As it appeared as though their potential concerns were 1 different than those initially presented by Councilmember Johnson, the two have been included in separate sections of the Council packet. • 1 It would appear from Jim Chaffee's response that the City can improve the overall regulation of jet skis via having our gate 1 attendants verify that both boats and jet skis are registered with the state. We can also check ages as well as inspecting both boats and jet skis for signs of water milfoil. This office would see both of those actions as being positive steps to promote overall 1 water safety. Staff could also be instructed to ensure that the boat access was clearly marked showing the counter-clockwise travel requirement and providing notice that violators will be cited. 1 Given the lateness of the receipt of the homeowner's petition, copying the enclosures referred to in Jim Chaffee's memorandum simply was not possible. Should the Council wish to pursue a 1 review of the Lake Minnetonka ordinance and/or the proposed state law changes, staff should be instructed to place such on the next regular agenda together with any actions proposed to be taken under either the visitor presentation item or this item. 1 1 1 1 13 4 CITY OF 1 CHANHASSEN 690 COULTER DRIVE • P.O.

IDATE: July 5, 1990 1 SUBJ: Water Ski Jets Councilman Jay Johnson would request an update on the water ski I issue as a part of the regular City Council agenda of July 23, 1990. He would anticipate some citizens being present and an early time on that agenda would be desirable. IPoints to be discussed include the necessity to have water ski jets registered and the age which must be attained for operation of I such. Jay, again, would like an update as to the current actions/ progress being made on the Lake Minnetonka ski jet ordinance/ controls. II would request that the information regarding the registration and licensing be submitted to this office as soon as possible. Assuming that there are state laws regarding registration/age, I I see no reason why the City cannot accelerate the probable conclusion from the July 23rd meeting, i.e. the City should be in a position of enforcing age limitations and ensuring that water ski jets are registered. (To ensure non-discrimination, we would I probably want to have our gate attendants verifying that boats were also properly registered. ) I Should you have any questions in regards to this memorandum, please feel free to contact me. 1 cc: Jay Johnson, Councilman Todd Hoffman, Recreation Supervisor Administrative Section, July 9, 1990 Council Packet 1 I I II CITYOF 4 ' II Ile CHANEAssrx ill, k4,.. .„ _ .

I You will note that in the attached Lake Homeowners Association is requesting diligent the fores of the water surface usage ordinance g diligent enforcement with the Carver County Sheriff 's Water aPatrol dan ' for strict enforcements of the rules. ) We have met and have asked II I II Don Ashworth ' Water Jetski Page 2 The petition also requests that the definition of motorboats be clarified. Staff feels that the present definition under our existing ordinance adequately describes any PWC. The ordinance defines motorboats as any watercraft propelled in any respect by ' machinery, including watercraft temporarily equiped with detachable motors. We would have no problem applying this ordinance to personal watercrafts . In addtion, we have discussed the ordinance application to PWCs with several members of the Lotus Lake Homeowners Association. It was agreed that section 6-48 of the ordinance would cover personal watercrafts operation within 100 feet of any shoreline. We are prepared to agressively enforce this portion of the ordinance against all watercraft on Lotus Lake given the ' available resources . The direction of travel for watercraft on Lotus Lake was also ' discussed. You will note that in the ordinance section 6-52 , it states that speeds in excess of 15 mph in other than a counterclockwise pattern of travel is prohibited upon Lotus Lake. This means that if PWCs are operating at less than 15 mph, ' they may operate in a clockwise pattern. In addition, nothing in our ordinance would prevent the PWCs from operating in a • very tight rotation in either direction. ' We also discussed the section of the ordinance regarding slow no wake areas (section 6-49) . This section states that no person shall operate watercraft in any marked slow/no wake ' areas in excess of slow/no wake speed. Slow/no wake areas shall be marked in accordance with the applicable regulations of the State Department of Natural Resources . The location and ' boundaries of each slow/no wake areas are established and are shown on that certain map entitled "Water Surface Use Zoning Map of Chanhassen" dated July 18, 1983, on file in the City ' Hall . Public Safety does have a few concerns regarding this particular portion of the ordinance. It would appear that it is a judgement call on the officers account to establish whether the violator is operating in a wake mode in a no wake area. Secondly, it specifically states that the area has to be marked slow/no wake. RECOMMENDATION: It is Public Safety staff ' s recommendation to actively support enforcement of the existing ordinance on Lotus Lake through the Carver County Sheriff ' s Department Water Patrol . We further recommend to continue to monitor progress regarding the LMCD ordinance regarding the operation of water jetskis on Lake Minnetonka. We will be receiving a copy of the State of II Don Ashworth Water Jetski I Page 3 Minnesota ' s bill that is being supported by the Minnesota I Department of Natural Resources , and would recommend that the City actively support such a law.
