This chapter is enacted in recognition of the following facts and for the following reasons:
A. Among the features that contribute to the attractiveness and livability of the city are its trees, both native and introduced, and its views of the San Francisco Bay area, obtained from the variety of elevations found throughout the city.
B. Trees, whether growing singly, in clusters, or in woodland situations, produce a wide variety of significant psychological and tangible benefits for both residents and visitors to the city. Trees contribute to the natural environment of the city by modifying temperatures and winds, replenishing oxygen to the atmosphere and water to the soil, controlling soil erosion, and providing wildlife habitat. Trees contribute to the visual environment of the city by providing scale, color, silhouette and mass, and by creating visual screens and buffers to separate land uses, and promote individual privacy. Trees contribute to the economic environment of the city by stabilizing property values and reducing the need for surface drainage systems. Trees contribute to the cultural environment of the city by becoming living landmarks of the city's history and providing a critical element of nature in the midst of urban congestion and settlement.
C. Views, whether of the San Francisco Bay with its vistas of the city of San Francisco, the varied bridges of the Bay Area, numerous islands and ships, or of the Oakland hills with its vistas of trees and the hills themselves, also produce a variety of significant and tangible benefits for both residents and visitors to the city. Views contribute to the economic environment of the city by substantially enhancing property values. Views contribute to the visual environment of the city by providing inspiring panoramic vistas, and creating distinctive supplements to architectural design. Views contribute to the cultural environment of the city by providing a unifying effect, allowing individuals to relate different areas of the city to each other in space and time.
D. It is recognized that trees and views, and the benefits derived from each, may come into conflict. Tree locations and species selections may produce both intended beneficial effects on the property where they are planted or occur as a result of natural regeneration as well as unintended deleterious effects on neighboring properties of equal or higher elevation. It is therefore in the interest of the public welfare, health and safety to establish standards for the resolution of view obstruction claims so as to provide a reasonable balance between tree and view related values for both private views and protected public views corridor.

For parklands, preserves or other types of open spaces, obstructions of protected public view corridors shall be eliminated or minimized in accordance with said management prescriptions. (Ord. 12622 (part), 2004: prior code § 7-8.035)

A. The claimant shall have no right greater than that which existed at the time of the claimant’s acquisition of the property involved in the view claim and shall provide evidence to provide the extent of said view.
B. The character of the view shall be determined by evaluating:
1. The vantage point(s) from which the view is obtained;
2. The existence of landmarks or other unique features in the view;
3. The extent to which the view is diminished by factors other than the tree(s) involved in the claim.
C. The character of the view obstruction shall be determined by evaluating:
1. The extent of the alleged view obstruction, measured to arrive at a percentage of the total view. Measurement of the alleged view obstruction shall be calculated by means of a surveyor’s transit, or by photography, or both;

d. Historic value.
E. Restorative actions shall be limited to the following:
1. No action;
2. Trimming;
3. Thinning;
4. Topping;
5. Tree removal with necessary replacement plantings.
F. Each type of restorative action shall be evaluated based on the above findings and with consideration given to the following factors:

2. Any adverse impact of the restorative action on the benefits derived from the tree(s) in question;
3. The structural and biological effects of the restorative action on the tree(s) in question;
4. The cost of the restorative action, as determined by consultation with licensed arborists located in Oakland.
G. All restorative actions shall be undertaken with consideration given to the following factors:
1. All restorative actions must be consistent with the tree preservation ordinance as set forth in Chapter 12.36 of this code.
2. Restorative actions shall be limited to the trimming and/or thinning of branches where possible.
3. When trimming and/or thinning of branches is not a feasible solution, topping shall be preferable to tree removal if it is determined that the impact of topping does not destroy the visual proportions of the tree, adversely affect the tree’s growth pattern or health, or otherwise constitute a detriment to the tree(s) in question.
4. Tree removal shall only be considered when all other restorative actions are judged to be ineffective and shall be accompanied by replacement plantngs of appropriate plant materials to restore the maximum level of benefits lost due to tree removal. Replacement plantings can be required on the tree owner’s or the claimant’s property.
5. In those cases where tree removal eliminates or significantly reduces the tree owner’s benefits of visual screening or privacy, replacement screen plantings shall, at the tree owner’s option, be established prior to tree removal; notwithstanding the provisions of subsection (G)(4) of this section, the tree owner may elect tree removal with replacement plantings as an alternative to trimming, thinning or topping.
6. All trimming, topping, thinning and tree removal required under this chapter must be performed by a licensed arborist. (Prior code § 7-8.04)

The cost of all restorative actions, replacement plantings, and arbitration shall be apportioned between the view claimant and the tree owner as follows:

A. Initial Reconciliation. A claimant who believes in good faith that the growth, maintenance, or location of trees situated on the property of another diminishes the beneficial use, economic value and enjoyment of views naturally accruing to the claimant’s property may notify the tree owner in writing of such concerns. The submission of said notification to the tree owner should be accompanied by personal discussions, if possible, to enable the claimant and the tree owner to attempt to reach a mutually agreeable solution to the alleged view obstruction under the terms and conditions of this chapter.
B. Arbitration. In those cases where the initial reconciliation process fails, the claimant and the tree owner may elect binding arbitration to resolve the alleged view obstruction. The view arbitrator shall be fully qualified under the terms and conditions of this chapter and shall be agreed to by both the claimant and the tree owner, who shall indicate such agreement in writing. The arbitration agreement may provide for employment of experts representing the parties or may be limited to an investigation of the view claim conducted by the view arbitrator. The view arbitrator shall follow the terms and conditions of this chapter to reach a fair resolution of the view claim, and shall submit a complete written report to the claimant and the tree owner.
