Annual Landscape Maintenance Calendar

Neighbors express interest in the calendar of our landscaping activities as outlined in the first table below. A local company, Gardeners' Guild, performs ongoing maintenance. We have a signed agreement with very specific weekly and monthly activities identified over the past years working together.

In addition to general landscaping maintenance, other professionals work for us who specialize in pruning and spraying trees and in performing larger-scale landscape improvements such as we've recently completed on the west end of Almenar and the north end of Via la Cumbre. Virtually every winter we prune our large heritage trees, planted along the curbs on many of our streets and in our medians, to ensure their health, beauty, and safety. Similarly, many of us are quite aware of the recent syndrome affecting a few oak species, Sudden Oak Death. We have top University of California and commercial experts consulting on and treating our trees when appropriate. This involves protective spraying during the year.

In the winter and spring (and as needed for safety), we prune shrubs back from the roadways. Then, flower buds develop to provide all the color we love in the spring and summer. And our larger landscaping improvement projects tend to be in the spring and fall, avoiding the heavy rain and erosion season, allowing for gentler rains and cooler seasons to establish our plantings. All of these efforts are complemented by the wildflowers and flowering perennials seeded regularly onto our open hillsides. Notice the colorful displays that begin in late winter and continue through early summer.

If you see areas for improvement, believe something needs to be done, please let us know via your Block Captain (see the 2nd table below), call our GPOA hotline, 461-7338, or send an email to landscaping@greenbrae.org. If it is a real emergency, call Gardeners' Guild at 457-0400.)

www.greenbrae.org…Your Community Website

In 2000, GPOA launched a community web site, www.greenbrae.org, to communicate current information on 'Sudden Oak Death' and other information of general interest and value to our community. On Greenbrae.org you will find links to Sudden Oak Death publications and professionals working hard to solve this syndrome. You can order the same wildflower and perennial seeds we sprayed this October on over 2 acres of open hillsides and medians across Greenbrae. This year the seed mix includes about 50 species and cultivars, from natives to desert species, in our ongoing program to beautify and continuously improve our shared landscaping. We have a Community Events Calendar for you to easily, and on your own, post activities of interest to the community. There is a Community Discussion Forum for you to post and discuss issues of interest. And, soon, we'll have an aerial, photographic map of the whole community for you to peruse. On our Home page, there's a place for you to share ideas with our GPOA Board of Directors. These are neighbors, just like you, who volunteer their time to support the community.

 
Our Next Landscape Improvements

We worked with our landscape architect and consultants to design irrigation and plantings for selected medians on Via la Cumbre, Bretano, Los Cerros, and Almenar. This past summer, we made major improvements to the west end of Almenar Drive (this completes the improvements begun when the utilities from Sir Francis Drake Blvd were moved there years ago) and to the northern end of Via la Cumbre. The plan is to build a decorative entrance wall at the northern end of Via la Cumbre.

Occasionally, neighbors contact us enquiring when their street's median will be improved. In time, we intend to make improvements across Greenbrae. It takes time, money, and personal effort (not just telling others you want it done). Medians and small islands with the highest visibility and traffic are being improved first. Thus, the greatest number of us can appreciate the improvements. As well, areas where eucalyptus were removed is a priority. If you want to participate in planning improvements to an island near your home, please help by organizing your neighbors and contacting GPOA at 461-7338.

 
Landscaping Budget

Our landscape improvements come from our County Service Area 16 (CSA 16) property assessment (not from our voluntary GPOA dues.) The bond issue last year to increase our assessment, to allow us to improve more medians faster, did not pass by the required 2/3's majority. Over 900 homeowners voted on this issue, and if 34 persons had voted for it rather than against it, it would have passed. But, since it was defeated, we are constrained to limited funds each year to make new landscape improvements. Several homeowners have expressed interest in getting their local neighbors together to fund their local island's improvements.

 
Annual Hydroseeding

This year at Halloween, we spent 2 days spraying seeds of wildflowers and flowering perennials onto medians across Greenbrae. You may have noticed the green slurry of seeds, mulch, and fertilizer sprayed from a huge hydroseeding truck onto our islands. Within the mulch are a broad variety of spring- and summer-flowering annuals and perennials. Each year the show is stronger as species take hold and self-sow. We've added more of the most successful plants to date, plus some new and highly promising species from areas similar to the diverse microclimates and soils we have across Greenbrae.

Each median and hillside has unique characteristics of exposure, soil depth, and rock. So, from the same mix of seeds, each area uniquely germinates and establishes itself. Some areas blossom with many species. In other areas we see only a few (or no) species germinating and growing to size. Yet, overall the number of wildflowers is increasing and many new areas are flowering as never before. Again, our most significant successes are along Almenar, Bretano, and Via la Cumbre-these are streets with large open hillsides. We will continue to seed these areas as well as Via Cheparro, Via Navarro, Via la Paz, and Via Barranca and hope to see an even better show of flowers everywhere in coming years.

In case you are interested in seeding your property, some of the species most successful to date include Clovers (in various colors and good for drawing nitrogen out of the air to the soil); Calendulas; California Poppy; Coreopsis; Farewell-to-Spring; Gazania; Lupines; Pride of Madeira; Tidytips; Baby Snapdragon; Shasta Daisy; and Yarrow. These are 'common names' and you can find them in the Sunset 'Western Garden Book.'

 
Order Your Own Wildflower and Perennial Seeds

On www.greenbrae.org, you can order the same seeds we used, and at a great price! This year, we used seeds from our reliable supplier in California and from a new supplier of desert species down in Texas. We are constantly adding to and adjusting the seed mix to maximize the show of flowers and to infill areas that have no plants. Go to our web site and order the seeds in small or large quantities…and let us know how it works for you.

 
Designing for Now and the Future

For those of you new to Greenbrae, our 'plant palette' and landscaping philosophy include native trees and shrubs (e.g., oaks, red buds, manzanitas, Matilija Poppies) and other plants (e.g., rosemary, Australian Fuchsia, Plumbago, Lemonade Berry) well adapted to our soils and environment-including our climate, deer, insects, and fungi. Plants are placed and selected according to many seasonal factors including flower color and size, leaf form and colors, and the size and density of the tree or shrub when mature (to provide some privacy yet retain views).

One goal is to enhance our landscape with beautiful plantings that require only limited maintenance and irrigation once established. This controls maintenance costs, frees up resources (e.g., money and irrigation water) for other improvements, and helps to ensure landscaping that flourishes and matures for generations to come. Other key goals include the protection of heritage trees, safety of pedestrians and vehicles, and mitigation of fire hazards.

 
Pruning

Late this December, during the dormant season, we again will prune heritage trees along curbs and in medians. This includes trees planted by Greenbrae's developers, such as Sycamores and Silver Maples, as well as native and planted Oaks, Bays, and Pines. The purpose is to preserve the trees by removing dead and dying branches, to create a strong branch structure to minimize structural failures, to ensure long-term beauty and safety, and to direct growth away from traffic into the islands. We credit the systematic, professional pruning and monitoring of our community trees for the quite limited branch and tree failures this November during the incredibly fierce first storm of the season.

Curbside trees are pruned to similar principles and we aim to develop canopied roads. If you want to see how this approach is working out, take a walk or drive up Corte Morada or the 1st block of Bretano Way. (Remember: if you have curbside heritage trees, do not prune them. GPOA does it professionally, with a consistent neighborhood look. We have this scheduled for the last week of December, 2002.)

We also prune out diseased and dying branches on small and large shrubs throughout our islands. Some older, disfigured and highly-woody shrubs are pruned to the ground to rejuvenate them. At first, this creates gaps. Healthy plants rejuvenate with fuller fountains of growth. This helps keep our hillsides green and growing and eliminates fuel that would readily burn in the undesired event of a hillside fire.

Please feel free to let us know what you think – at GPOA's hot line, 461-7338, via your Block Captains, and at landscaping@greenbrae.org. We love to hear the compliments as well as the suggestions. It's only when we really hear from you that we can address specific issues. Here's wishing you a happy and healthy holiday season!
