Helix is a Special District

A special district is a local government agency formed by voters to perform a  needed service, such as water or sewer. Most are governed by a Board elected from their communities and are effective service providers because they are held to high standards of transparency and accountability.

Open Meetings

The Ralph M. Brown Act requires that the public is notified of Board meetings and able to attend.

Full Disclosure

The Fair Political Practices Commission requires Board members and Helix staff to file a Statement of Economic Interest annually, reporting any gifts or monies received.

Ethics Training

Assembly Bill 1234 requires Board members to attend ethics training upon election or appointment, and re-certify every two years.

Financial Audits

State law requires special districts to submit regular audits performed by a certified public accountant to ensure public funds are properly managed. The audits are public documents filed with the state and county controller.

Public Review

Special districts must upload their financial reports and Board member and employee compensation to the state controller’s website for public review.
