I'll transcribe and try to sum up some of San Diego's:
County of San Diego:
Measure A: San Diego County road repair, transit, traffic relief, safety and water quality measure.
40 year half-cent local sales tax to fund basic road repair, public transit and water pollution prevention.
Measure B: Ordinance amending the county general plan, county zoning map and county code, and adopting the Lilac Hills Ranch specific plan.
Amends general county zoning plan to allow for a specific new housing development (1,746 houses + commercial centers + parks/trails)
City of San Diego:
Stadium boondogles:
Measure C: Downtown stadium intiative.
Increases hotel room tax from 10.5% to 16.5% and removes existing 2% room tax for tourism marketing to fund a $1.8 billion stadium/convention center annex downtown. Basic breakdown of costs: Stadium $650 million (private), land aquisition $200 million (public), convention center $600 million (public), joint use portion $350 million (public).
Measure D: Facilities and tourism tax initiative.
Increases hotel room tax from 10.5% to 15.5% and removes existing 2% room tax for tourism marketing. Channels funds for downtown convention center, but specifically not a contiguous expansion to the current convention center. Creates overlay zone for convention center and sports facilities and allows for current stadium property's sale for education/park use. Honestly the whole things is a bit convoluted in its goals and impact.
The rest:
Measure E: Charter Amendment regarding qualifications, vacancy, and removal for mayor, city attorney and council.
Measure F: Charter Amendment regarding required term of service for certain terminations or suspensions of deputy city attorneys.
Measure G: Charter Amendments regarding the citizen's review board on police practices.
Measure H: Charter Amendments regarding purchasing and contracting processes for the city of San Diego.
Measure I: Charter Amendment regarding Balboa Park and San Diego High School.
Measure J: Charter Amendment regarding use of lease revenue from mission bay park.
Measure K: Charter Amendment requiring run-off election for the offices of mayor, city attorney and council member.
Measure L: Charter Amendment requiring citizen's initiative and referendum measures to be placed on November general election ballots, unless the council decides to submit them to voters earlier.
Measure M: Affordable housing: increasing the limit on the number of units the city and certain public agencies are allowed to help develop.
Measure N: Non-medical cannabis business tax.
Establishes a gross receipts tax on pot businesses in the city if Prop 64 is approved.
