The spending plan calls for using a mixture of gas taxes, vehicle registration fees, the state's general fund, the petroleum inspection fund and bonding toward rebuilding Milwaukee's Zoo Interchange and Hoan Bridge, improving harbors, preserving railroad tracks and training new State Patrol recruits.

He's also proposing adding 67 new auditors and investigators at the Revenue Department.

Walker's budget would lay out more than $7 million for raises for assistant prosecutors and public defenders.

The budget would provide $4.4 million for raises for assistant district attorneys. It also would provide nearly $3 million for raises for assistant attorney generals and assistant public defenders. Walker said the raises are necessary to retain experienced staff and ensure effective prosecutions.

The public safety portion of the budget also calls for police to collect DNA from anyone arrested on suspicion of a felony and a host of misdemeanors. Walker has been signaling for months the spending plan would include that initiative.

His budget also would require GPS monitoring for high-rise offenders subject to restraining orders and eliminating the state Office of Justice Assistance.

Walker's budget doesn't raise hunting or fishing license fees but pumps millions of dollars more into combating aquatic pollution.

The budget Walker released Wednesday would provide an additional $24 million to reduce nonpoint water pollution as well as $85,000 for measuring lake water quality.

The budget would implement a number of recommendations a Texas researcher made to the state Department of Natural Resources last summer on how to improve the agency's relationship with deer hunters, including creating mini-hunts, creating updated maps of the state and continuing chronic wasting disease surveillance.

The budget also would allow the DNR to use $10.5 million in stewardship land acquisition dollars on road repairs and boat access improvements on stewardship property as well as for renovations at the Kettle Moraine Fish Hatchery.

Walker is also proposing a statewide elimination of residency laws that require employees to live in the city or school district where they work.

Milwaukee city officials, including Democratic Mayor Tom Barrett, oppose such a move, which Walker had indicated he may pursue before unveiling his plan. The city's residency rule on the books since 1938.

Removing the residency requirement for Milwaukee schools has been debated for years in the Legislature but never passed. The residency requirements vary across the state and in some places, like Madison and Green Bay, it applies only to agency heads and not rank and file workers.
