ARCHITECTURAL GUIDELINES OVERVIEW The objective of the Design Guidelines is to provide a framework for helping to shape the architecture and landscape within a pedestrian friendly community by constructing homes developed from the building traditions of the Northwest and the rural vernacular. The guidelines should not limit creativity, but should encourage a variety of building solutions that will complement each other. It is the responsibility of every Owner and architect/builder to become familiar with the Design Guidelines. . The construction process at Discovery Bay begins with understanding how to proceed with the Design Review Process. This ensures that each Owner will be a good neighbor and have good neighbors. Section 2 describes the Design Review Process. Sections 3, 4, and 5 address specific design requirements, both mandatory and discretionary, followed by Section 6 that deals with construction regulations. The objective of these Design Guidelines and the Design Review Board (ORB) is to preserve, protect and enhance the existing forest and natural environment around Discovery Bay and avoid harsh ,contrasts between the natural landscape and anything built upon it. Homes should incorporate unique design solutions that are responsive to the specific Homesite's topography, regional climate, and rural environment. Implementation of the design objectives is the responsibility of the Discovery Bay Association (the "Association") and the DRB on a site-specific basis. The duties and responsibilities of each of these entities are also set forth in the Declaration of Covenants, Conditions, and Restrictions for Discovery Bay. , \ . MAY -) )f " h \)\ . I .

LANDSCAPE STANDARDS OVERVIEW The beauty of Discovery Bay resonates from the many wonderful distant vistas punctuated with sunset and sunrise views of the bay itself, The challenge of landscape design is to seamlessly merge the built environment with the natural setting, This will be accomplished primarily through limiting the introduction of non-native plant material. Please appreciate that your first neighbors are the wildlife that has lived at Discovery Bay for years, The existing native vegetation has survived the foraging patterns of your wildlife neighbors and offers you an excellent example of which plants will flourish within your building envelope. Successful landscaping at Discovery Bay will embrace the variety of native plants unique to your Homesite and complementing them with a minimum of plants selected from the Approved Plant List (a Preliminary Plant List has been attached). 5.1 General Design Consideration . The challenge of landscape design constructed is to harmoniously integrate building structures and other elements into the natural setting rich with intrinsic values and to perpetuate the existing landscape, To ensure that the original environment and the intrinsic character will be preserved, there will be a limit to the quantity of plants that do not naturally occur within the Discovery Bay area, Non-native plant material is restricted to the Private Areas within your Building Envelope that are screened from public view, Plant composition should include sizes and quantities that mimic what is naturally occurring on your Homesite, The goal is to save or recreate a landscape that appears native and flows seamlessly, The objective of landscape design is to ensure that the natural environment is preserved, protected, and enhanced, This requires an especially sensitive approach to landscape design that starts with the protection and preservation of the existing environment and provides the foundation for the experience of living at Discovery Bay. This will be accomplished by maintaining a Nature's Envelope that results from containing the majority of all construction activity within the designated Building Envelope, 5.2 Homesite Area Construction activity including grading, building site access and the storage of materials, all must occur within the Building Envelope, Construction activity that may occur outside the Building Envelope includes driveways, utilities, BMPs, and any revegetation of preexisting disturbed areas, Therefore, all constructed improvements, (i.e. screen walls, retaining walls, decks, and all other landscape elements, etc,), shall be located within the Building Envelope. The function of the Building Envelope is to define the maximum allowable buildable area on your Homesite and to contain the extent of impact resulting from construction. Each Homesite consists of three distinct zones with unique landscape characteristics: the Nature's Envelope, the Transitional Area, and the Private Area. . 5.2.1 Nature's Envelope Area The Nature's Envelope area is that portion of each Homesite that lies outside of the Building Envelope and must remain natural and undisturbed, The Nature's LOG ITEM # _ rL( Page 1 _oUL \ MAY - 9 2005 " r' , ':. ; 1- '.Ji"; ~ L~;'l,,:.,~. . Envelope includes all indigenous vegetation and land features such as drainage corridors and steep slopes, rock outcroppings, and open space easements, Landscaping within the Nature's Envelope area is restricted to cleaning of debris and limited tree limbing to enhance views and remove dead limbs, Any portion of the Nature's Envelope that is disturbed during construction shall be re-vegetated to a natural state at the Owner's cost. Due to the short growing season a sub- alpine environment, supplemental irrigation may be required to establish the native plant material. Trees may continue on the drip irrigation system; however it is recommended that once they are established the supplemental irrigation be decreased and eliminated, If the Nature's Envelope area is not re-vegetated the Design Review Board will evaluate the disturbance and cost of restoration and the Homeowner/Contractor will be billed for the cost. The final construction approval will be withheld until payment is received, Approval from the Design Review Board must be granted prior to performing any work in the Nature's Envelope area except for construction of the driveway. 5.2.2 Transitional Area . The Transitional Area is that portion of the Building Envelope that is beyond the wall of a residence or improvement and is visible from adjacent properties, streets, or public spaces. The purpose of the Transitional Area is to provide a transition between the Nature's Envelope Area and the Private Area, This Transitional Area should incorporate native densities, sizes and plant species that enable the landscape design to blend into the Nature's Envelope area. Only the plants found on the Approved Plant List in Appendix B may be used within the Transitional Area, 5.2.3 Private Area The Private Area is that portion of the Building Envelope that is not visible from adjacent properties, streets, public spaces, or common areas. The Private Area is intended to be the least restrictive with respect to the plants that may be planted within this area, The Private Area will be the smallest landscape area within the Building Envelope, This is the least restrictive area for plant material and the only area where non-native or ornamental plants may be introduced, Their survival rate is limited due to wildlife and the sub-alpine climate, It is recommended to limit the use of non-native or ornamental plant material and to utilize the Approved Plant List found in Appendix B-1, The overriding landscape goal is to ensure a harmonious blending with the surrounding native mountain environment. Therefore, the visibility of any turf areas and/or other non-indigenous plants must be screened and contained from adjacent Homesites, streets, and common areas, .
