Presentation Overview Case Studies Drakes Landing - Bay Friendly Rated, Sheet Mulching Process & Water Savings The Willows – Eco Gardens - Arboretum All-Stars & Community Event Harbor Bay Medians - Bay Friendly Rated, Largest Sheet Mulching Project in Bay Area & 75% projected water reduction Return on Investment – Paying for Renovations Water Use Reductions Maintenance Cost Reductions Sustainable Solutions in Design & Planning Soil Development & Management Fertigation Organic Installation & Maintenance Collaboration – Contractors & Architects
Drakes Landing – 1st Bay Friendly Certified Commercial project in Marin Owner/ Property Manager: Equity Office Properties Commerical Office Park in Larkspur Landscape Designer: Susie Dowd Markarian Completion Date: November 2009 Over 2 acres of lawn were sheet mulched and replaced with low water use plants More than 75% of the plant palette is low water use plants No turf was installed All shrub beds were converted from spray to drip irrigation
Typical Commercal Landscape
Shut off the water Cut the grade at the perimeter, and spread the waste material to sheet mulched over – Zero Waste Project Big Cut / Labor Intensive – a profile is 3” of compost and 3” of mulch, that is tapered back into the landscape.
2 layers of cardboard, overlapped and watered down. Then 3” of compost Cost – on our projects We have found it be only slightly more money to sheet mulch in lieu of the conventional herbicide, rototill w/ 6 cyd/1000sf of nitro.
Hydroseeding the wildflower mix Water Quality Protection Practices Sheet mulching eliminates the need for chemical preemergents and saved 10.45 lbs of Glyphosate herbicide AND 174,000 lbs of grass, roots and dirt from landfill. • Long term maintenance includes Integrated Pest Management • No additional impervious surfaces were added.
Planting and Drip irrigation in process
From the California Water Efficient Landscape Ordinance Prior to Renovation MAWA – Maximum Applied Water Allowance – 2.6M Gallons ATWU – Actual Total Water Used – 2.5M Gallons After Renovation ETWU – Estimated Total Water Used - 2M Gallons ATWU – Actual Total Water Used – 1.2M Gallons 1.4M Gallons/Year or 53% savings after renovations

create a sustainable, water conserving and habitat enhancing landscape that sets a new eco friendly image design intent is to replace the existing turf landscape with a green, eco landscape following the Bay Friendly Landscape Guidelines (BFL) Current estimated water usage for the medians is 3.6 million gallons per year which will be reduced approximately to +/- 1.2 million gallons per year, more than 65% water conservation savings through this design approach.

ROI Quantifying savings in operating costs can sell projects – Water & Maintenance Installation of SMART / ET Controllers can reduce was use by up to 30% and pay for themselves in 1-5 years. Example 8 year old HOA, Altamar at the Ridge, in Brisbane (south of SF) Water is over $9/unit base rate with an average annual rate increase of 12% Install of 11 Hydropoint Controllers, over $50K, paid for in 1 year Typical Landscaping 10 years+ ROI Drakes Landing & Harbor Bay Medians as examples Too far out for many investors to value – similar to the challenge with Solar (17-20 years) Some customers, that don’t flip properties, see value… Community & Environment Education – water, energy, pollution Connecting the quantifiable changes with a project Make an emotional appeal – Polar Bears Saved Create community events

Building Healthy Soils As I have recently learned about soil biology, I have become an advocate and created so many opportunities on our projects. Educating customers, employees and myself… Testing Soil Biology – levels of Bacteria, Funji, Protozoa, Nematodes & Mycorrnizal Colonization Re-specifying or substituting Organic Compost for Nitro (still the dominant spec) Promoting Sheet Mulching in lieu of traditional renovation methods – retain the soil life & Organic matter Applying Compost Tea & Bio-stimulants – regenerate soil biology Proposing Fertigation Systems to deliver organic fertilizer and bio-stimulant Applying compost to turf areas in lieu of fertilizer
The nitrogen-rich compounds found in fertilizer run-off is the primary cause of a serious depletion of oxygen in many parts of the ocean, especially in coastal zones; the resulting lack of dissolved oxygen is greatly reducing the ability of these areas to sustain oceanic fauna. About half of all the lakes in the United States are now eutrophic, while the number of oceanic dead zones near inhabited coastlines are increasing. Fertigation Nutrient Absorption 95% + compared to 10% with dry granular Labor to apply reduced by 90% - Reduces labor & material costs (ROI of 1 year) - Reduces Harmful fertilizer run-off - Reduces water use Healthier plant material also reduces insect and disease activity Why not?
Soil Foodweb Model – who has heard of it? #1 Tool for any landscape manager…. Healthy, living soils feed our landscapes without the need for synthetic fertilizer. Healthy soils reduce water use, reduce maintenance costs and transition us from hurting to healing.
