Garden Tour Sneak Peek: The Art of Lawn Replacement

Posted on April 23, 2019 at 9:40 AM by Ann Vallee

Garden Tour Preview This quaint garden in Fairfax proves that good things really do come in small packages! An exceptional example of a turf replacement project, its balance of landscape and art is truly inspirational. 

Interested in taking advantage of the State of California’s Turf Replacement Rebate, owner and professional landscaper Teliha decided to transform the previous lawn into a beautiful spiraling pathway. Matching the theme of mosaics found throughout the garden, each recycled stone is individually decorated with unique clusters of patterned tile or recycled beads, and the pathway is set in sand to make it permeable. Also replacing part of the lawn are native, low-water-use plants and a few veggie crops. Along the lower section of the garden is a creative solution to keeping unwanted visitors at bay: Swathed in vibrant wisteria vines, a column and cable retaining wall keeps deer out without sacrificing the view.


On the day of the Eco-Friendly Garden Tour, May 4, Teliha will be giving a presentation called "The Art of Lawn Replacement" at 11 a.m. and 2 p.m.—definitely one not to miss! Don't forget to register for the free tour to see this beautiful garden in person and to learn more about lawn replacement techniques.

Infrastructure Investments Help Ensure Clean, Reliable Water for the Future

Posted on April 22, 2019 at 3:36 PM by Ann Vallee


sgtp for blog
Constructed in the 1950s, San Geronimo Water Treatment Plant is one of MMWD’s three water treatment facilities. We’re in the midst of a series of phased upgrades to the plants that will extend the lifespan and improve the reliability of our water treatment operations. 
When you turn on your tap and clean water comes out, it’s not by accident. It takes a large and complex system to capture, store, treat and deliver water to your home or business 24/7/365. Though much of that water infrastructure is out of sight, it’s never out of mind for MMWD.

As the oldest municipal water district in California, we face significant challenges in maintaining our aging infrastructure. Parts of our water system date back more than 100 years. Many of our pipes, tanks and pump stations are reaching the end of their useful lives. Over the past 10 years, we’ve invested more than $200 million in capital projects to maintain our system. We expect to invest as least as much over the next 10 years to ensure a clean, reliable water supply for the future.

In short, when you pay your water bill, you are getting much more than just the water you use. You are also helping to take care of the complex system—from reservoirs to pipelines—needed to deliver that water to your tap. 

Did You Know?
  • Marin’s varied topography makes our water system unusually complex. To move water throughout our service area, we rely on 97 pump stations and 128 storage tanks—that’s an order of magnitude more infrastructure than many water agencies our size. 
  • MMWD maintains more than 900 miles of pipeline. Laid end to-end, our pipes would stretch from Marin into Canada! Almost half of our pipes are 50 years or older. 
  • With 18,500 acres of watershed land on Mt. Tam under our care, MMWD is the largest public land manager on the mountain. We’re fortunate to have a source of high-quality water in our backyard, but caring for our watershed lands has a cost. With support from our customers, we’re working to manage the impacts of invasive pest plants and climate change, and to reduce the risk of wildfire to our community.

Garden Tour Sneak Peek: Sophisticated Downslope Water Garden

Posted on April 8, 2019 at 9:57 AM by Ann Vallee

Garden Tour Preview 2 Owned by a planting and green roof designer, this sloping landscape preserves mature oak trees and southern views of Mt. Tamalpias. Several new low-impact design technologies are employed: permeable pavers, rain gardens, swales, bioretention basins and a green roof. The upper and lower garden levels are connected by a grand staircase unfolding onto a meadow of low-water-use grasses. The design incorporates rock outcroppings, stone, concrete and corten retaining walls, all intertwined by a soft path of redwood timbers and crushed stone. The landscape professional who contributed to its design is Holly Selvig of Holly Selvig Landscape Architecture.
