When completed, the community will contain a balanced mixture of land uses, a diversity of housing types, recrea-tional amenities, commercial and light industrial activities, and community facilities such as schools, parks, churches and necessary support facilities. 7 The "neighborhood village" concept is used for the entire project. Each village is delineated by one or two dominant residential themes or land uses. These are oriented toward parks or similar amenities to further define the individual neighborhood within the village. The villages are linked by a landscaped pedestrian/vehicular circulation network to provide appropriate access and to unify the overall development. Streetscenes with landscaped open areas are accented by coordinated wall details, paving textures, signage, lighting and street furniture, and entry monuments. Proper landscaping and entry monuments create a formal, dramatic entry experience which defines the individual village identity. Landscape and other buffers are used in transition areas in order to integrate adjacent land uses and to provide an element of privacy which is essential to quality residential living. Architectural elements throughout the project utilize natural tones, textures and materials to reinforce the cohesive community character. All colors within the project shall compliment one another. 8 The following guidelines are formulated in a broad performance standard approach which allows flexibility and encourages innovative design con-cepts. They will provide a general design framework for all residential land uses within the community. 3.2 MASTER PLAN 3.2.1 All development proposals shall be consistent with the land use designations and circulation network defined in the Master Plan for Green Valley. 3.3 SITE GRADING AND IMPROVEMENTS 3.3.1 GRADING Goal: Establish compatible relationships between buildings, landscape areas, parking and adjacent properties with grading techniques that are safe, aesthetic and cost effective. 1. Grading should: a. Minimize soil instability by limiting disruptions of natural ground forms. b. Reflect the recommended procedures as outlined in current soils reports for the area. c. Create interest by complementing existing earth forms. d. Ensure adequate site drainage. e. Provide attractive building sites designed to natural terrain. f. Maximize view potential. 2. Grading should result in a graceful recontouring of the land rather than a large amount of harsh geometric slope banks and pads. TRANSITION AT TOP AND TOE OF SLOPE THIS NOT THIS 3. There should be a smooth, gradual transition where graded slopes meet natural terrain. These slopes should also reflect the flowing natural character of the terrain. Grading and siting techniques should respect natural drainage features and, where possible, utilize these water courses to carry the runoff. THIS NOT THIS 5. Lot grading should be kept to a minimum. Roads and structures should be located for maximum preservation of natural grade and vegetation. 6. Any grades, berms, channels and swales should be an integral part of the grading concept. 7. Surface and sub-surface geological factors shall be respected as determined from grading plan submissions, i.e., rock/caliche, ground water, difficult soils, etc. 8. Methods of grading should be discussed as to export/import situations, pollution control, caliche excavation and removal, if any. 3.3.2 EROSION PREVENTION DURING CONSTRUCTION Goal: Prevent loss of soil by water and wind erosion by creative grading and building techniques. 1. Practical combinations of the following technical principles should be used to provide effective sediment control, a. Expose smallest practical area of cleared land during con-struction. 10
