Time to ditch those disposable cups, San Marcos river-goers. The city is clamping down on single-use beverage containers in a big league way, with a new ordinance kicking in on May 1 that bans these environmental no-nos along the San Marcos River and in certain city-owned parks, Spectrum Local News reports. The "Reuse at the River" campaign is toeing the green line, pushing for visitors to switch to reusable drinkware like those made of stainless steel, durable plastic, and silicone, according to Spectrum Local News.

The crackdown includes a sweep on cans, plastic water bottles, juice pouches, Styrofoam cups, plastic party cups, and anything that's designed to be used once and then tossed according to the report. If you’re planning on relaxing with a cold one riverside, remember the rule of one: one cooler per person, topping off at a 30-quart capacity, and make sure it's latched tight to avoid any unintentional littering, which nobody wants. Jamie Lee Case, the Parks and Recreation Director, has high hopes, telling Spectrum Local News, “This is a huge step forward for our community and the health of our river,” as stated in Spectrum Local News.

No citations, just education until April 30, 2025, Community Impact explains. And not to worry, there are still "Go Zones" where you can glug your store-bought drinks to your heart's content, including Ramon Lucio Park and a sprinkling of other green spaces.

So remember, starting in May, it's a no-go for single-use sippers in the "No Zones" areas. There will be signage reminding individuals that only reusable containers will be allowed, primarily along the riverbanks, as per Community Impact.
