Mayor Walter E. Washington unveiled his 1977 legislativce proposals decriminalize minor traffic offenses and urging Congress to give the greater home rule and full voting representation in Congress.

The package of more than 150 legislative items contains many proposals previously introduced but acted upon before last year's adjournment of Congress and the City Council.

"I think we're very hopeful that the overwhelming number of these things will be adopted," said Judith Rogers, the mayor's special assistant for legislation, she said, 67 of 84 legislative proposals by the mayor were approved in some form by the Council.

One of the major new proposals from the mayor would allow creation of a civilian authority to handle minor traffic and parking offenses that now are resolved in D.C. Superior Court.

Douglas N. Schneider Jr., director of the transportation department, said specifics of the plan will not be made final for another month. Generally, Schneider said, minor cases would be heard by civilan officers rather than judges.

The plan is designed to cut down a heavy traffic violations case load and speed up the processing procedure for such offenses. The proposal also includes a request to beef up the city's traffic force for ticketing, towing and impounding cars and placing "boots" that immobilize vehicles whose drivers have unpaid tickets.

Another legislative proposal would require licensing of paramedics who staff the city's 11 specially-equipped mobile intensive care units and also provide liability insurance for doctors who give advice to the paramedics over the telephone during emergency treatment.

The mayor also is asking the Council fro legislation that would require the installation of approved smoke detectors in all city residences.

Many of the other proposals to be given to the Council involve updating existing laws that have become outmoded during the 105 years that the District has been without home rule, Rogers said.

For example, the city's standards on licensing veterinarians are still governed by a 1907 law passed when animal husbandry was the principal concern of such doctors, she said. "The standards and sophistication of the trade have changed a lot since then," Rogers said.

The mayor also wants authority for the city to sign longer term contracts - which he says would save the city money - and sell up to $100 million in general obligation bonds, once a congressional audit of city finances is complete. Currently, the city has $50 million in bonding authority.

In addition to full voting representation in Congress, which would replace the city's single nonvoting delegate with two senators and at least two representatives, the mayor to impose a commuter tax.
