  12. 12. What is sustainable landscaping?Because that is what Build it Green is trying to accomplish!Sustainable landscaping encompasses a variety of practices that have developed in response toenvironmental issues. These practices are used in every phase of landscaping, including design,construction, implementation and management of residential and commercial landscaping is….. Designing/installing plant material that is appropriate for the specific site, whether the plant material is native or adapted to the soil, weather, and rainfall. Working with nature through the development of construction & maintenance specifications, including soil preparation, irrigation design, plant material, herbicides, etc Using sustainable materials in the construction of site elements Using new technology and practices, including rain-water harvesting, graywater recycling, high efficiency irrigation system, SMART irrigation controller, etc. Following and/or superceding CALGreen Building Code, State and/or City Model Water Efficient Landscape Ordinance
  13. 13. Desirable Landscape Features in Residences:  Attractive, innovative, water conserving and low maintenance  Year-round showing of color, foliage and flowers  Contrasting colors, range of colors provided, varying heights and spreads  Alternatives to lawn and high water use plants/features (except in backyards and/or select locations in front yard)  Vegetable plots  Herb gardens  Fruit trees  Sustainable installation methods with planting and irrigation  Water saving irrigation equipment  SMART irrigation controller, “you set it and leave it”  Use mulch!  Water feature in an appropriate location (high maintenance)  A horseshoe or bocce ball court for entertaining
  14. 14. Build it Green ChecklistLandscape needs to be a minimum of 15% of the site to beeligible for 35 GreenPoints. If not, there are 6 points to receive.1. Group plants by Water needs (hydrozoning). 2 POINTS (MWELO) When irrigating the landscape, design the irrigation system around the plant material it is watering. Put high water use plants together with other high water use plants that have the same sun exposure. Don’t mix high and low water use plants! State MWELO requirement as well Bay Friendly Landscape Guidelines
  15. 15. Build it Green Checklist2. Mulch all planting beds to the greater of 3 inches or local water ordinance requirement. 2 POINTS (MWELO, Bay Friendly (BF)) A perfect depth of mulch for native plants is 2-3 inches. Most local ordinances require 2 inches or more, and therefore, for Build it Green, 3 inches would be the depth. Mulch at 3 inches deep encourages moisture retention, health in the soils and reduces weed germination and moderates the temperature of the soil!
  16. 16. Build it Green Checklist3. Construct Resource-Efficient Landscapes. 5 POINTS (1 on A, 1 on B, 3 on C) (BF) a) No invasive species listed by Cal-IPC (Invasive Plant Council at Plants that have been identified as pests and or invasive are not allowed with Build it Green. Acouple of examples below: Pampas Grass and Agrostis.
  17. 17. Build it Green Checklist3. Construct Resource-Efficient Landscapes. 5 POINTS (1 on A, 1 on B, 3 on C) (BF) b) No plant species will require shearing. This would include hedges, large shrubs in small spaces and many other instances.
  18. 18. Build it Green Checklist3. Construct Resource-Efficient Landscapes. 5 POINTS (1 on A, 1 on B, 3 on C) c) 75% of plants are drought tolerant, California natives or Mediterranean species. Plant California natives that are appropriate for the space, for the site environment, and for the use.
  19. 19. Build it Green Checklist4. Minimize turf in landscape installed by Builder 6 POINTS (2 on A, 4 on B) (MWELO) a) Turf shall not be installed on slopes exceeding 10% and no overhead sprinklers installed in areas less than 8 feet wide.
  20. 20. Build it Green Checklist4. Minimize Turf in Landscape installed by Builder 6 POINTS (2 on A, 4 on B) b) Turf is small percentage of Landscape Area (2 points for <25%, 4 points for <10%) The more turf is limited on your development, the more points you will receive!
  21. 21. Build it Green Checklist5. Plant Shade Trees 2 POINTS Trees that are large enough to shade the roof and pavement on your site are shade trees. Examples of large drought tolerant shade trees (preferably deciduous) are Coast Live Oak, Valley Oak, Red Maple, and many more. Quercus agrifolia Acer rubrum Quercus ilex. Quercus lobata
  22. 22. Build it Green Checklist6. Install high efficiency irrigation systems 5 POINTS (2 on A, 3 on B) (MWELO) a) System only uses low-flow drip, bubblers or sprinklers These systems are much more efficient than an overhead spray system. They provide point-source irrigation. b) System has SMART (weather-based) controller. These controllers are based on CIMIS irrigation information that tracks temperature, wind, solar exposure, rainfall and more.
  23. 23. Build it Green Checklist7. Incorporate two inches of compost in to the top 6 – 12 inches of soil 3 POINTS (BF) Compost can range in material from yard waste that has been composted, green food, vineyard waste and much more. Check out some suppliers we use:Sonoma Compost: N Grow:
  24. 24. Build it Green Checklist8. Rainwater Harvesting System 3 POINTS (1 on each A, B or C) a) Less than 750 gallons of storage capacity b) 750 gallons to 2,500 gallons of storage capacity c) Greater than 2,500 gallons of storage capacity
  25. 25. Build it Green Checklist9. Irrigation system uses recycled wastewater 1 POINT If recycled wastewater is available from your water utility, you can gain one point for the use of this water. Generally, unless the project has its own wastewater treatment plant, it is only available if the City has recycled wastewater available.
  26. 26. Build it Green Checklist10. Submetering for Landscape irrigation 1 POINT (some MWELO) Some municipalities require the submetering of the landscape irrigation. The submeter is to be installed after the point of connection for the irrigation system.
  27. 27. Build it Green Checklist11. Design Landscape to meet water budget 2 POINTS (1 for A, (MWELO) 1 for B) a) Install irrigation system that will be operated at < 70% reference ET b) Install irrigation system that will be operated at <50% reference ET These irrigation points will be dependent on the types of plant material used, the types of irrigation equipment used and the scheduling used by the maintenance/homeowner.
  28. 28. Build it Green Checklist12. Use environmentally preferable materials for 70% of non- plant landscape elements and fencing 1 POINT (MWELO/CALGreen) a) FSC Certified Wood b) Reclaimed materials c) Rapidly renewable materials d) Recycled-content e) Finger-jointed f) LOCAL materials
  29. 29. Build it Green Checklist11. Reduce light pollution by shielding fixtures and directing light downward (CALGreen) 1 POINT This point will be gained, if lighting fixtures are used and if there are specific specifications requiring the use of special shields, directional lighting, etc.
