Workforce Housing & Housing Tax Credit

The act allows a board of county commissioners and the governing body of a municipality to sell and dispose of property owned by the county or municipality, as applicable, to provide for affordable housing and allows a municipality to enter into a long-term rental or lease agreement for the development of affordable housing.     The act allows for the approval of a mutijurisdictional housing authority at a biennial local election instead of only during a general election or an election held on the first Tuesday in November of an odd-numbered year. The ballot question about establishing the authority may be combined with a question about a tax, impact fee, multiple-fiscal year debt, or other financial obligation.     The act allows a board of county commissioners to use ad valorem tax revenue for housing authorities, housing programs, and workforce housing.     The act entitles an entity subject to income tax to which a middle-income housing tax credit is transferred by a governmental entity or quasi-governmental entity to claim the credit without owning an interest in a qualified project.     The sale and use of construction materials by contractors is exempt from taxation if the materials are used by the state in its governmental capacity only. The act provides that 'governmental capacity' includes the construction of workforce housing projects undertaken by counties.(Note: This summary applies to this bill as enacted.)

Water Projects Eligibility Lists

Maddy summaryThis bill approves specific updates to eligibility lists for two Colorado water funding programs. It adds new drinking water projects (like Delta County's distribution system) and modifies existing entries (such as adding "green infrastructure" to Loveland's project), while deleting completed projects (like Kiowa's). These changes determine which local water districts, municipalities, and property associations can access financial assistance from the Drinking Water Revolving Fund and Water Pollution Control Revolving Fund.

Protecting Colorado's National Public Lands

Maddy summaryThis Senate Joint Resolution expresses Colorado's legislative support for maintaining national public lands under federal stewardship and opposes efforts that would reduce public access or weaken environmental review laws. The resolution specifically targets potential erosion of bedrock federal laws like NEPA and FLPMA, which require public input and balanced resource management. It calls on state and federal officials to defend statutory safeguards that ensure public lands serve broad public benefits rather than narrow special interests. This non-binding resolution does not change any laws but serves as a formal statement of legislative intent and values regarding public land management.

John 'Jack' Thurman Memorial Highway" in honor of a World War II Marine Corps veteran.

Coal Transition Community Investment

The act establishes a first and preferred opportunity for available employment for coal transition workers in coal transition communities (hiring preference). A business entity located in a coal transition community that is engaged in the business of constructing or operating railroads, utilities, energy generation facilities, or advanced manufacturing facilities (covered business) is required to comply with the hiring preference. A covered business does not include the state government or a local government.     A covered business is required to make good faith efforts to provide a hiring preference to a coal transition worker who meets the qualifications for an employment position (qualified coal transition worker). A covered business may hire an individual who is not a qualified coal transition worker only if a qualified coal transition worker did not apply for employment with the covered business, each qualified coal transition worker declined a job offer from a covered business, or a qualified coal transition worker's qualifications did not meet the qualifications of other candidates for the same job.     If a qualified coal transition worker applies for employment with a covered business, the covered business is required to report specified information annually to the just transition office. The executive director is required to adopt policies and procedures to implement the act. A hiring preference does not apply if a covered business places an existing employee in another employment position with the covered business or to the extent that a hiring preference conflicts with the terms of a collective bargaining agreement that applies to the relationship between a covered business and its employees.     Currently, a public entity is not allowed to invest public funds in certain types of investments, such as equity instruments, instruments convertible to equity, or equity interests, or to deposit public funds with any person except certain depository institutions, which are primarily banks. The act authorizes a public entity to deposit or invest, either directly or through an investment firm or other third party authorized by the public entity, public funds from a payment or settlement that the public entity has received to offset the socioeconomic impacts to a community or government from the closure of a coal mine or coal power generating station in any investment permitted by an investment policy approved by the public entity.(Note: This summary applies to this bill as enacted.)
