2026 New York General Election

Here are some bills that should be easily passed if not for politics:

Legislation to ensure Nassau’s opioid settlement funds are used only for treatment, prevention and recovery services
A proposal to establish a gas tax holiday to provide relief at the pump amidst soaring fuel prices
“Gio’s Law” which would equip Nassau police vehicles with epinephrine auto-injectors (EpiPens)
“Robbie’s Law,” which would install external defibrillators (AEDs) at all county-owned and operated athletic fields
A proposal to establish a 311 non-emergency hotline – which would have been especially useful during recent blizzards
Legislation to slash the outrageous and illegal fees Nassau homeowners are charged at the County Clerk’s office
Recognizing Juneteenth as an official holiday - like every other town, county or city in our region.

The County must comply with the courts instead of continuing to defend fees that have already been deemed excessive.
Instead of spending taxpayer dollars fighting to preserve a broken fee system, we should be fixing it. This legislation restores fairness and puts Nassau residents first. I am proud to stand behind this legislation and put money back in our neighbors’ pockets.

Deeply concerned with protecting our community from drugs and addiction, Legislator DeRiggi-Whitton has hosted numerous Narcan training sessions to help educate the public on the dangers of drugs and how to administer this potentially lifesaving treatment.

Demanding Action On Opioid Crisis

Delia and her Minority Caucus colleagues are demanding the immediate restoration of $13.7 million in opioid settlement interest and investment income after the money was inappropriately transferred out of the account meant to fight addiction and into the County’s General Fund.

“We cannot allow funding meant for treatment and prevention to be delayed while families are still losing sons and daughters,” Delia said. “This money must be restored and put to work right away.”

Continuation of SEPTIC Program Boosts Environmental Protection Efforts

In March, Delia proudly voted to commit another $2 million in state funds to help homeowners replace aging septic systems.

Eligible Nassau homeowners can be reimbursed for up to 50 percent, capped at a total of $10,000, of the cost of replacing their septic system, or 75 percent of the expense, up to $25,000, for enhanced septic through the S.E.P.T.I.C. (Septic Environmental Program to Improve Cleanliness) program.

Crescent Beach Reopens This Summer

After 17 years of hard work and persistence, Delia is thrilled to announce the Nassau County Department of Health has approved the reopening of Glen Cove’s Crescent Beach for swimmers during the 2026 season!

This was done by employing creative and cutting-edge approaches, such as installing Helix filter systems and a box culvert near the base of the stream, utilizing plantings that naturally absorb bacteria, and creating a new conduit to reduce bacteria levels. Since becoming a Legislator, Delia has secured nearly $1 million in County-level bond authorization to fund improvements that enhanced water quality and will continue to do so in the future.

7. Sustainable Development (p. 9)
I am a strong supporter of community-driven development that emphasizes the principles of smart growth, environmentally friendly LEED construction principles, and preservation of green open spaces. As I described earlier, robust mass transit and walkability are core elements of sustainable development, and modern septic systems and sewer infrastructure will unlock additional opportunities for environmentally sound economic development and downtown revitalization.

Delia DeRiggi-Whitton.docx (NYLCV 2021 Candidate Questionnaire PDF)

Before being elected to the Nassau County Legislature, DeRiggi-Whitton served two terms as a member of the Glen Cove City Council. Long active in senior affairs, she was the Council's liaison to the City's Senior Center and was a member of the City's Senior Advisory Board. As a Legislator, she has actively worked on and filed legislation to keep senior tax abatement legislation in place for the 2017 property tax bill.

3. Transportation (p. 6)
I strongly support transit-oriented and sustainable development. Better mass transit options will also make our communities more walkable, and the sum of these parts will reduce our carbon footprint by empowering people who do not want to drive to pursue a car-free lifestyle without any limitations. One way I followed through on this vision is by securing funding to restore shuttle bus service connecting the Port Washington and Roslyn train stations to better serve industrial parks and senior-living facilities along the route.

One way I followed through on this vision is by securing funding to restore shuttle bus service connecting the Port Washington and Roslyn train stations to better serve industrial parks and senior-living facilities along the route. Nassau County has also continued to provide robust financial support for mass transit (NICE bus) to supplement lost revenue streams caused by a sharp reduction in ridership during the pandemic.

2. Energy (p. 5)
I fully support efforts to increase the County’s reliance on “green” and renewable energy sources such as solar and wind power to reduce our reliance on fossil fuels and improvements to our infrastructure that will make it easier to utilize alternatives such as electric and alternative-fuel cars. Furthermore, I am an ardent opponent of fracking and at the local level spearheaded efforts to enact bipartisan legislation that prohibits the County from using snow-melt pellets made from fracking water.

6. Clean Water (p. 8 - 9)
I am deeply committed to improving water quality and have supported efforts to bolster our sewer infrastructure within my district and throughout our region. The Legislature continues to strongly support the Bay Park Conveyance Project, a nearly half-billion dollar investment in establishing state-of-the-art waste management systems that will greatly enhance the ecological health of the Western Bays and Reynolds Channel.

In addition, I played a role in completing a sewer study in coastal portions of my district, advocated for replacing failing streamside septic systems and assisted in efforts to secure $12 million to repair degrading sewers in Glen Cove. I will continue to be an advocate for improvements in this realm and remain committed to finding long-term solutions for remediating the contamination of Crescent Beach and preserving our single-source aquifer.

In an age of ever-increasing development, I believe it is essential to protect and conserve our natural environment through County-led preservation efforts and emphasizing smart development choices that blend economic development while maximizing the preservation of green spaces in our county. The COVID-19 pandemic only served to further underscore the importance of these spaces as the interest in safe, socially distanced outdoor activities and recreation increased dramatically. I support Nassau County’s efforts to acquire and preserve open space not only for use and enjoyment by the public, but also protect environmentally sensitive parcels and protect our single-source aquifer from contamination and the risk of salt-water infiltration.
