means a property owner (or legal occupant with written permission of the property owner) who alleges that trees located on the property of another person are causing unreasonable obstruction of his or her pre-existing views or sunlight.

F.

"Pre-existing view or sunlight"

G.

"Primary living areas"

§ 8.13.030. Process for resolution of claims.

To establish view and sunlight rights recognized and established herein, the claimant must follow the process established by this Chapter. First, the claimant must complete the "initial discussion" process described below. Second, if that process does not yield a result mutually satisfactory to the claimant and the tree owner, then the claimant must seek to mediate his/her view/sunlight claim in accordance with this chapter. If the tree owner refuses to mediate or if the mediation is unsuccessful in resolving their differences, then the claimant must attempt to initiate arbitration as set forth hereinafter. If arbitration is not accepted by the tree owner, and the initial discussion and mediation have proved unsuccessful in resolving the view/sunlight claim, the claimant may then initiate litigation to determine his/her view/sunlight claim rights. Except in instances regarding city owned property, no city action or decisions are required to establish or exercise a claimant's view/sunlight rights.

A. Initial discussion. A claimant who believes that tree growth, maintenance or location on another person's property diminishes the beneficial use, economic value and enjoyment of views of his/her property shall first notify the tree owner in writing of such concerns. The notification should be accompanied by personal discussions to work towards a mutually agreeable solution.

  1. If the Parties Agree: Following the initial discussion, if agreement is reached between the parties as to the existence and nature of the claimant's rights and on what restorative action is to be taken on the tree(s) in question, that agreement shall be reduced to writing and executed by all parties concerned. Said agreement must set forth the following:

a. Establishing the claimant's right under Section 8.13.021;

b. Specifying the detail of said right; and

c. Specifying the nature and timing of the action and the parties responsible for performing said action required to effectuate the said rights so established.

  1. If the Parties Do Not Agree: If the parties do not agree as to the rights in question and what action should be taken regarding the tree(s) in question, the claimant must prepare and provide the tree owner a view/sunlight claim and provide a copy of the view/sunlight claim to the City.

B. View/sunlight claim. A "View/Sunlight Claim" shall consist of the following:

  1. A description of the nature and extent of the alleged obstruction, including pertinent and corroborating physical evidence. Evidence may include, but is not limited to, photographic prints, negatives or slides. The evidence must show absence of the obstruction at a point in time during the tenure of the claimant's ownership or occupancy of the claimant's property. Evidence to show the date of property acquisition or occupancy by the claimant must be included;

  2. The location of each tree alleged to cause the obstruction, the address of the property upon which the tree is located, and the present tree owner's name and address;

  3. Evidence of the failure of initial reconciliation, (Section 8.13.030 A) to resolve the dispute. The claimant must provide physical evidence that a written attempt at reconciliation has been made and failed. Evidence may include a copy of and receipt for certified or registered mail correspondence;

  4. Specific restorative action proposed by the claimant to resolve the unreasonable obstruction.

C. View sunlight claim process.

  1. Mediation. If the initial discussion fails to achieve agreement between the tree owner and the claimant, then the claimant, in order to preserve and perfect his/her rights hereunder, shall prepare and deliver to the tree owner a written offer ("offer notice") to submit the dispute to mediation to settle the dispute. Acceptance of mediation by the tree owner shall be voluntary, but the tree owner shall have no more than 30 days from service of the offer notice either to accept or to reject the offer of mediation. Failure to respond within 30 days after the service of the claimant's offer notice shall be deemed rejection of the offer of mediation. If mediation is accepted, the parties shall mutually agree upon a mediator within 21 days of the date the tree owner's acceptance of the offer notice, and should commence mediation within 60 days after the tree owner's acceptance of the offer notice.

The mediator shall use and be governed by this chapter in attempting to help resolve the dispute. The mediator does not have the power to issue binding orders for view or sunlight restorative action, but shall strive to enable the parties to resolve their dispute by written agreement in order to eliminate the need for arbitration or litigation.

  1. Binding arbitration. Where the initial reconciliation and mediation are declined or fail, the claimant shall submit to the tree owner a written offer to propose binding arbitration ("arbitration notice"). The acceptance of binding arbitration by the tree owner is voluntary. The tree owner has 30 days from service of the arbitration notice to either accept or reject binding arbitration. Failure to respond within said 30 days shall be deemed to be a rejection of the offer of arbitration. If binding arbitration is accepted, the parties shall agree on a specific arbitrator within 21 days of the date of the tree owner's acceptance, and shall indicate such agreement in writing. If the parties do not agree on a specific arbitrator within said 30 days, either party may petition the court to appoint an arbitrator.

The arbitrator shall use and be governed by this Chapter to reach a fair resolution of the view/sunlight claim and shall submit a complete written decision to the claimant and the tree owner. This decision shall include the arbitrator's findings with respect to the applicable provisions of Sections 8.13.040 and 8.13.050 of this Chapter, a pertinent list of all mandated restorative actions with any appropriate conditions concerning such actions, and a schedule by which the mandated actions must be completed. The decision of the arbitrator is enforceable under the California Code of Civil Procedure. A copy of the arbitrator's decision shall be submitted by the claimant to the Community Development Department immediately after it is received by the claimant.

  1. Litigation. If arbitration is declined by the tree owner, the claimant may pursue civil action for resolution of his/her view/sunlight claim rights. The litigation must state in the lawsuit that arbitration was offered and not accepted. The litigating claimant shall file a copy of the lawsuit with the City Community Development Department.

c. Soil stability, as measured by soil structure, degree of slope and extent of tree(s) root system;

d. Wildlife habitat.

e. Screening of nearby residences or other structures and, if the tree(s) is restored as proposed by the claimant, the effect such restoration would have on views of the tree owner.

f. Visually pleasing settings or qualities in their own right.

  2. Potential for replacement of removed trees and the number of trees existing in the area;

  3. The variety of tree, whether the tree is a protected tree or has historic value;

  4. Economic value of the tree as measured by the International Society of Arboriculture; and

  5. The hazard posed by a tree to a person or structure on the property of the claimant including, but not limited to, fire danger and the danger of falling limbs or trees.
