PROVIDENCE — Several environmental bills are poised for votes and hearings this week. One of the most significant for supporters of open-space protection is an amendment (S2591 and H7651) to state building laws that allow wetlands to be included in calculations that determine a buildable lot and the number of units per lot.

The so-called “Dry Lands” bills are opposed by the Environment Council of Rhode Island (ECRI) and Save The Bay. Both organizations point to legislation passed by the General Assembly in 2015 that creates statewide standards for wetland buffers and setbacks. The regulations have yet to be issued by the Department of Environmental Management (DEM). ECRI and Save The Bay say those standards are needed before new building rules can be acted on by the General Assembly.

DEM is seeking a six-month extension to write those wetland regulations. Both bills are scheduled to be heard April 27 at Senate Committee on the Environment and Agriculture.

The relaxed building rules are supported by the Rhode Island Builders Association (RIBA). The construction advocacy group insists that the legislation gives cities and towns the right to control development. During a March 10 House hearing, William Walsh, a RIBA lobbyist, said the effort reverses a trend that makes it hard to build what he called “middle-class housing.” Those impediments include the high price of open space, large lot requirements, and excessive regulatory burdens and expenses “that continue to thwart the recovery of the building industry as well as the state,” he said.

In 2013, then-Gov. Lincoln Chafee signed into law a bill that allows unbuildable sloped land to be considered part of a buildable lot size.

Healthy food advertising. A bill that would prohibit the advertising of food and drinks that are not allowed in schools passed the Senate on April 14. The House Committee on Health, Education and Welfare will hear the bill next. The advertising would be prohibited from school buildings, buses, athletic fields, scoreboards and vending machines. The bill is backed by the American Heath Association and the American Cancer Society.

Light bulbs. The Senate Committee on the Environment and Agriculture will hold a hearing for a bill that would establish a statewide drop-off program for light bulbs that contain mercury, such as compact fluorescent light bulbs.

Solar permitting. The Senate passed a bill that would create a task force to study the creation of statewide permitting regulations for installing residential and small-scale commercial rooftop solar installations. The bill was referred to the House Finance Committee.
