Did you know there are more than nineteen thousand licensed dogs with the Marin Humane Society? That’s more than fourteen thousand pounds of dog p**p a day!

To protect the water quality in our creeks, bays and ocean, and the health of our families, it's important for all dog owners to pick up after their pets and keep harmful pathogens out of our waterways!

Things to Know Thursdays - Green Stormwater Infrastructure

The terms Green Stormwater Infrastructure (GSI) and Low Impact Development (LID) are similar approaches to stormwater management that protect, restore, or mimic the natural water cycle in the urban environment. Simply put, the goal is to divert stormwater into natural areas where the water can be filtered and infiltrate rather than run directly into storm drains and carry pollutants into our creeks.

Things to Know Thursdays - Cover Your Load / Cubra su carga

It’s a California State Law to have your loads covered when operating vehicle on streets. Trash and debris from an uncovered load can fly away while driving your vehicle and eventually make its way to our storm drain system and waterways. Tips for covering your load https://www.streetstocreeks.org/trash-what-can-i-do

Es una Ley del Estado de California que cubra sus cargas cuando conduce un vehículo en las calles. La basura y la suciedad de una carga descubierta pueden volar mientras conduce su vehículo y, finalmente, llegar a nuestro sistema de desagües pluviales y vías fluviales. Consejos para cubrir su carga https://www.streetstocreeks.org/trash-what-can-i-do
