Development and Design Standards
The character of all streets will vary by specific location. Some streets are required to carry a large volume of both automobile and pedestrian traffic and provide a more intense experience, while others will provide more intimately scaled street-space. |
Standard cross-sections for collector and local roadways are provided. Cross-sections for major and minor arterial roadways are determined on a case-by-case basis depending upon specific site conditions. |

Rating | Description | General Criteria |

2 | Good to Fair | The tree is typical of the species and/or has less than 20% dead wood in the crown, only one or two minor problems that are easily corrected with normal care. |
3 | Fair | The tree is not typical of the species and/or has less than 30% deadwood in the crown, one or two minor problems that are not eminently lethal to the tree, and no significant decay or structural problems, but the tree must have remedial care above normal care in order to minimize the impact of future stress and to ensure continued health. |
4 | Fair to Poor | The tree is typical of the species and/or has significant problems such as 30% to 50% deadwood in the crown, serious decay or structural defect, insects, disease or other problems that can be eminently lethal to the tree or create a hazardous tree if not corrected in a short period of time or if the tree is subjected to additional stress. |
5 | Poor | The tree is not typical of the species and/or has over 50% deadwood in the crown, major decay or structural problems, is hazardous or is severely involved with insects, disease, or other problems, that even if aggressively corrected, would not result in the long-term survival of the tree. |
