The City of Elk Grove desires to preserve the existing trees within the City whenever reasonably possible. The City wants to preserve the historic and aesthetic character of the community as described in the General Plan, of which older trees are a critical component. In doing so, the City is establishing these regulations as a way to protect the health and integrity of the City’s existing urban forest while providing for an optimal level of species and age diversity. Further, the City recognizes that trees provide numerous benefits to the community, including improving water quality, providing shade for buildings, providing shelter for animals and other plants, and reducing pollution, thereby positively impacting the health and welfare of the community. Older, more mature trees are often the most effective types of trees for achieving these objectives. These provisions are intended to complement and strengthen zoning, subdivision, and land use standards and regulations, while at the same time recognizing the rights of individual property owners. It is, therefore, the objective of these provisions to preserve existing trees through both the development review process and subsequent activities such as work within the canopy or within the critical root zone of trees and provide a process for replacement in instances where preservation is not reasonably possible.

A. Landmark Tree Generally. A landmark tree is a tree that has been determined and designated, by resolution of the City Council, to be of high value to the community because of its species, size, age, form, historical significance, or some other professional criterion.
B. Process for Designating a Landmark Tree.
1. Any person may submit a proposal to designate a tree as a landmark tree. Proposals shall be submitted to and reviewed by the Development Services Director. The Development Services Director shall route the application to the City Arborist for review and comment. Upon review and recommendation by the Development Services Director and City Arborist, the proposal shall be submitted to the City Council for review and action.
2. If a tree proposed as a landmark tree is located on private property and the property owner is not the person submitting the proposal, the application shall be routed to the property owner for their review and comment.
3. The City Council may only approve designating a tree(s) as a landmark tree if the property owner has given their consent to the designation.
C. Criteria for Landmark Tree. A tree may be designated a landmark tree if it meets any of the following criteria:
1. The tree is an outstanding specimen of a desirable species;
2. The tree is one of the largest or oldest trees in the City;
3. The tree is of historical interest;
4. The tree is of distinctive form; or
5. The tree is an unusual species, significant grove, or is otherwise unique.
D. Benefits of Landmark Tree Designation. Owners of property upon which a landmark tree is located are eligible to receive benefits for the care and maintenance of their landmark tree. Typical benefits may include:
1. Discounts by participating local contractors and arborists for work on landmark trees. The City does not guarantee that discounts will be given in all cases but may work with landmark tree owners in securing a contractor discount on an individual basis.
2. Owners shall receive a resolution of appreciation from the City Council.
3. Free consultation and advice from the City Arborist for the landmark tree.
E. Removal of Landmark Tree Designation. The designation of a tree as a landmark tree may be removed based upon the following process:
1. If the landmark tree is located on private property, the property owner shall submit a request for removal of landmark tree designation to the Development Services Director.
2. If the landmark tree is located on City property or within the public right-of-way, the Public Works Director shall submit a request for removal of landmark tree designation to the Development Services Director.
3. The Development Services Director shall review all requests for removal of landmark tree designation and route the request to the City Arborist for review and recommendation. The City Arborist shall prepare a report identifying the health and character of the landmark tree. The Development Services Director shall then prepare a report and recommendation for the City Council.
4. The City Council shall consider the recommendation of the Development Services Director and City Arborist and take action to either retain or remove the landmark designation of a tree. Removal of landmark tree status shall be completed through adoption of a resolution of the City Council. [Ord. 24-2015 §8 (Exh. F), eff. 2-12-2016; Ord. 6-2011 §4, eff. 3-25-2011]

[Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 6-2011 §4, eff. 3-25-2011]
A. Application Procedure.
1. Generally. When a tree permit is required by this chapter, the person or property owner desiring to complete the work shall make an application for a tree permit to the Development Services Department on a form provided by the City. The application form shall be accompanied by the following information so that the City may adequately review the request. The application may cover one (1) or more trees.
a. A brief statement of the reasons for the proposed work;
b. Consent of the owner of record of the land on which the proposed activity is to occur;
c. A tree survey with the accurate location, number, species, size (DSH), critical root zone (CRZ), and approximate age (if known) of the tree or trees subject to the application;
d. If the project involves other discretionary development, then this survey must be part of the total development plan and must also describe any tree or trees which could be affected by the proposed development, and accurate trunk locations shall be indicated on all construction plans;
e. Payment of any permit fee or deposit shall be authorized by City Council resolution; and
f. Any other pertinent information requested by the City Arborist.
B. Tree Removal as Part of a Development Project. When a development project proposes the removal of trees, no separate application for a tree permit shall be required as part of the application for the development project. However, all the information required under subsection (A) of this section must be included with the development project application and no trees shall be authorized for removal until:
1. The entitlement has been approved; and
2. City staff has field-verified that proposed tree removal is consistent with the approved plan. It shall be the responsibility of the applicant to contact the City for field verification prior to tree removal. Trees to be removed shall be clearly identified in an arborist report and properly marked in the field.
C. Approving Authority. The designated approving authority for tree permits shall be as provided below:
1. Tree Located on Private Land and Not Part of a Development Project. For tree permit work on privately owned land and not in conjunction with a discretionary development project, the Development Services Director shall be the designated approving authority. The Development Services Director shall make a decision on the tree permit application after a recommendation has been provided by the City Arborist.
2. Tree Located on Private Land and Part of a Development Project. For tree permit work that is part of a discretionary development project, the approving authority shall be the same as the approving body for the relevant land use entitlement(s). The approving body shall make a decision after a recommendation from the City Arborist or City staff as a part of the overall development project recommendation. Requests for amendments to the original tree permit work that were approved by the designated approving authority as part of a discretionary development project may be amended by the Development Services Director if either of the circumstances below are present.
a. Deterioration of a qualified tree originally designated for protection when such deterioration is documented and the tree is recommended for removal by the City Arborist; and/or
b. Unforeseen changes or circumstances to the site, structures, or adjoining property impacting a qualified tree designated for protection.
The Development Services Director may elevate amendments to the original approving authority at his/her sole discretion.
3. Tree Located on City-Owned Land. For qualified trees (landmark trees, secured trees, and/or trees of local importance) in the right-of-way and on City property, the Development Services Director shall be the designated approving authority. The Development Services Director shall make a decision on the permit after a recommendation has been provided by the City Arborist and the Public Works Director.
D. Permit Process.
1. Except where otherwise provided by this chapter, a tree permit shall be exercised within twelve (12) months from the date of approval, or other time limit established through a concurrent development project approval. Time extensions, for up to a total of two (2) additional one (1) year terms, may be granted in compliance with the following provisions. A tree permit not exercised within its time limits shall expire in compliance with EGMC Chapter 23.18 (Implementation, Time Limits, and Extensions).
a. Time of Filing. The applicant shall file a written request for an extension of time with the Development Services Director before expiration of the permit, together with the required filing fee.
b. Evidence to Be Provided. The Development Services Director shall determine whether the applicant has made a good faith effort to exercise the permit. The burden of proof is on the applicant to establish, with substantial evidence, that circumstances beyond the control of the applicant (e.g., demonstrated financial hardship, poor weather during periods of planned construction, etc.) have prevented exercising the permit.
c. Action on Extension Request. A tree permit may be extended as follows for no more than two (2) additional one (1) year periods beyond the expiration of the original approval; provided, that the approving authority first finds that there have been no changes in the conditions or circumstances of the site or project such that there would have been grounds for denial of the original project.
i. Development Services Director’s Action. Upon good cause shown, the first extension may be approved, approved with modifications, or disapproved by the Development Services Director, whose decisions may be appealed to the Planning Commission, in compliance with EGMC Section 19.12.130 (Appeals).
ii. Planning Commission Action. One (1) subsequent extension may be approved, approved with modifications, or disapproved by the Planning Commission, whose decisions may be appealed to the City Council in compliance with EGMC Section 19.12.130 (Appeals).
2. If a permit is denied, the Development Services Director shall provide written notification, including the reasons for denial, to the applicant.
3. It shall be the responsibility of the person conducting the permitted work to have the tree permit or a copy of the conditions of approval imposed by the approving body at the tree removal site.
4. The permit, or the conditions of approval granted by the approving body, shall entitle the applicant to conduct the approved work on the tree(s) identified under the permit. All other work outside the scope of the approved permit shall be considered a violation of this chapter. [Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 24-2015 §8 (Exh. F), eff. 2-12-2016; Ord. 6-2011 §4, eff. 3-25-2011]
Prior to the consideration of a request for tree removal by the designated approving authority or grading within the critical root zone of a qualified tree, the applicant shall retain an ISA certified arborist to prepare a report. The report shall identify the basis, if any, for supporting the removal of the qualified tree(s) and shall be subject to review by the City Arborist. The arborist report shall include an analysis of the following factors:
A. The condition of the tree with respect to disease, general health, damage, structural integrity, and whether or not the tree acts as a host for an organism which is parasitic to another species of tree which is in danger of being exterminated by the parasite;
B. The number of existing trees on the subject property, on adjacent property, and immediately proximate to the subject tree(s) as deemed relevant by the City Arborist, and the effect of the tree removal upon public health and safety, and prosperity of surrounding trees;
C. The number of healthy trees that a given parcel of land will support, with and without the proposed development;
D. The effect of tree removal on soil stability/erosion, particularly near water courses, drainage ditches, or on steep slopes, or the effect on runoff interception;
E. Present and future shade potential with regard to solar heating and cooling;
F. Identification of alternatives that would allow for the preservation of the tree(s) proposed for removal; and
G. Any other information the City Arborist finds pertinent (e.g., site conditions, other vegetation, and utility service). [Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 6-2011 §4, eff. 3-25-2011]
A. Review by Designated Approving Authority. The approving authority shall determine, after preparation of the arborist report and a recommendation by the City Arborist, whether or not the tree(s) cannot or should not be retained. The determination of the approving authority in granting or denying a tree permit for tree removal shall, at a minimum, be based upon the factors analyzed in the arborist report.
B. Findings for Permit Issuance. The designated approving authority shall make at least two (2) of the following findings as part of the approval of a tree permit for tree removal:
1. For development projects, every effort has been made to integrate the existing tree(s) into project design, including the use of minor deviations and/or variances.
2. The effect of the removal of the tree will not negatively impact the health, safety, and prosperity of surrounding trees, or the aesthetics and general welfare of the area.
3. The tree presents a threat to public health and safety and must be removed.
C. Findings for Permit Denial. The designated approving authority shall make all of the following findings as part of the denial of a tree permit for tree removal:
1. Removal of the tree is inconsistent with the standards for tree removal as provided in this section; and
2. The denial of the permit for tree removal will not unreasonably compromise the owner’s rights to enjoy and develop the property. [Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 6-2011 §4, eff. 3-25-2011]
As part of the approval of a tree permit for removal of a tree, the designated approving authority shall require mitigation for the loss of the tree consistent with Article IV (Mitigation for Tree Loss) of this chapter. The requirement for mitigation may be waived under those circumstances provided in EGMC Section 19.12.180 (Alternative mitigation requirements). [Ord. 6-2011 §4, eff. 3-25-2011]
The decision of the designated Approval Authority shall be final unless an appeal is filed in compliance with EGMC Section 23.14.060 (Appeals). [Ord. 6-2011 §4, eff. 3-25-2011]
When mitigation for tree loss is required by this chapter or through the CEQA process, mitigation shall be provided consistent with this article. [Ord. 6-2011 §4, eff. 3-25-2011]
When tree removal is authorized as part of issuance of a valid tree permit, mitigation for the loss shall be provided at a ratio of one new inch DSH of tree for each inch DSH lost (1:1 ratio), unless an alternative mitigation is approved by the City as provided in EGMC Section 19.12.180 (Alternative mitigation requirements). The applicant for the tree permit shall prepare a tree mitigation plan for review and approval by the City Arborist. Only the mitigation authorized under an approved mitigation plan shall be used. [Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 6-2011 §4, eff. 3-25-2011]
Unless an alternative mitigation is approved by the City as provided in EGMC Section 19.12.180 (Alternative mitigation requirements), the City allows all of the following mitigation options, subject to review and approval by the City Arborist, as part of a tree mitigation plan. Mitigation measures or conditions of approval on a project, as imposed by the designated approving authority, may specify which options are available to an applicant.
A. On-Site or Off-Site Replacement. The plan shall specify where the tree(s) shall be planted and how the tree(s) shall be monitored and maintained for a minimum of five years. The City may require the establishment of a performance bond or other surety as a way to ensure that the replacement trees survive for the minimum establishment period as provided in EGMC Section 19.12.190. The City will allow the use of on-site trees planted under a mitigation plan as a way to meet any other on-site landscaping requirement, including parking lot shading, street landscaping, and street trees on residential lots.
B. Payment of an In-Lieu Fee as Adopted by Resolution of the City Council. The applicant may pay an in-lieu fee for the loss of the tree(s) at a rate established by the City Council. Such monies shall be deposited in the tree preservation fund as described in EGMC Section 19.12.220.
C. Credit for Existing Trees Smaller Than When a Permit Is Required. An applicant may be entitled to mitigation credit when they preserve species of trees that are listed in EGMC Section 19.12.040 (Trees of local importance) but are smaller than the size threshold defined in EGMC Section 19.12.040 (i.e., less than six (6") inches DSH). The City Arborist shall make the determination after reviewing the location of the tree(s), the quality of the environment (both pre- and post-project) in which the tree(s) is located, potential impacts to the tree(s) from proposed development, and other relevant factors that the City Arborist deems relevant to the long-term viability of the tree(s). If approved for credit, retained trees shall receive a credit of one (1") inch DSH per tree for trees between two (2") and five (5") inches DSH. The City may require the establishment of a performance bond or other surety as a way to ensure that the tree(s) survive for the minimum establishment period as provided in EGMC Section 19.12.190. [Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 6-2011 §4, eff. 3-25-2011]
A. Except when funded through the tree preservation fund, trees planted as mitigation shall be of an equivalent species as those being removed. For instance, a tree of local importance shall be replaced with another tree of local importance. Landmark trees shall be replaced with a species or species to the satisfaction of the City Arborist, with consideration given to species diversity and ensuring that the right tree is planted in the right location.
B. The following equivalent sizes shall be used whenever new trees are planted (either on site or off site) under a mitigation plan:
1. Smaller than fifteen (15) gallon container = one (1") inch DSH.
2. Fifteen (15) gallon container or larger = two (2") inch DSH. [Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 6-2011 §4, eff. 3-25-2011]
A. Authority and Findings for Granting Alternative Mitigation. The designated approving authority may allow for an alternative mitigation standard than otherwise required under this section; provided, that one (1) of the following findings is made:
1. The tree is diseased, as diagnosed by the City Arborist, and is not treatable;
2. The tree is causing or has a high degree of probability to cause significant property damage to existing structures (e.g., damage to a building foundation, roof, or similar); or
3. The tree is or has a high degree of probability to be a hazard to the public health and safety (e.g., likely to fall into the roadway or onto a habitable structure).
The simple proximity of a tree to a habitable structure or roadway shall not, in and of itself, be grounds for a waiver of the mitigation requirement. Rather, the tree must be, in the opinion of the City Arborist, exhibiting indications that it is likely to fall in the direction of the structure or roadway.
B. Alternative Mitigation Required. In granting an alternative to the mitigation requirement, the designated approving authority shall require that the applicant mitigate for the loss of the tree by requiring that a new tree (minimum fifteen (15) gallon container) be planted in place of the removed tree unless the City Arborist determines that there is no feasible space remaining on the project property for a new tree. The species and final planting location shall be subject to review and approval of the City Arborist to ensure, to the greatest degree possible, that the new tree will not create a similar circumstance in the future. [Ord. 20-2017 §3 (Exh. A), eff. 10-13-2017; Ord. 6-2011 §4, eff. 3-25-2011]
A. Replanting security shall be required for any tree mitigation plan excluding payment of an in-lieu fee. The purpose of such security shall be to guarantee the applicant’s compliance with conditions of approval and City provisions regarding tree protection and preservation. Security may also be required at the discretion of the approving body to insure the completion of any additional work specified as a condition of permit approval or other approvals.
B. The security shall be in the amount of one hundred (100%) percent of the estimated cost of the required work. The applicant shall include the cost estimate as part of the tree mitigation plan for City Arborist review and approval. The terms and conditions of the security shall be reviewed and approved by the Development Services Director prior to approval of the tree mitigation plan.
C. The security may be in the form of a letter of credit, cash deposit, a combination thereof, or other acceptance method of security by the City and shall be approved by the City Attorney.
D. Security posted on actual work required shall be maintained for a minimum of five (5) years. The City may require additional length of security of up to ten (10) years when larger trees are being planted and/or site conditions warrant.
E. Any interest gained on security posted by requirement of the City shall accrue to the applicant or his or her designee. [Ord. 24-2015 §8 (Exh. F), eff. 2-12-2016; Ord. 6-2011 §4, eff. 3-25-2011]
The approving authority may mandate any or all of the following control measures to mitigate damage to trees protected through new development project approval:
A. A circle with a radius measurement from the trunk of the tree to the tip of its longest limb plus one (1' 0") foot shall constitute the critical root zone of all trees to be retained and all portions of off-site tree driplines that extend into the site, and shall not be cut back in order to change the dripline. Removing limbs which make up the driplines does not change the protected zones.
B. Chain link or City-approved barrier shall be installed one (1' 0") foot outside the critical root zone of the on-site tree(s) to be retained and all portions of off-site tree(s) driplines that extends onto the site, prior to initiating project construction, in order to avoid damage to the trees and their root systems. The barrier around a tree’s critical root zone may be moved to allow building construction when such encroachment has been previously authorized. The new barrier locations shall be four (4' 0") feet outside the structure wall and/or driveway location. Orange plastic netting is not a permitted barrier type.
C. All driveways which pass through the critical root zone of the on-site trees to be retained and all portions of off-site tree driplines which extend on the site shall be constructed such that the entire driveway section is placed directly above existing grade. No excavation or scarification for driveway construction shall be allowed within the critical root zone except as approved by the City Arborist.
D. Any pruning of retained trees shall be supervised by a certified arborist and shall be completed to the most current ISA standards (“Tree Pruning Guidelines”) and ANSI A300 standards. Branch and limb pruning shall be limited to that which has been deemed necessary in order to correct a safety hazard, structural defect, crown cleaning, or arborist recommended pruning in the tree. Pruning due to canopy encroachment by buildings shall be limited to the minimum amount needed to safely accommodate the structure while still maintaining the tree.
E. All trees on site shall be pruned, as per City Arborist recommendations, prior to starting any site improvements. Any pruning of a tree shall be supervised by a certified arborist.
F. No signs, ropes, cables (other than those which may be recommended by a certified arborist to provide limb support) or any other item shall be attached to the on-site trees to be retained and all portions of off-site tree driplines which extend onto the site.
G. No vehicles, construction equipment, mobile home/office, supplies, materials or facilities shall be driven, parked, stockpiled, or located within the CRZ area of the on-site trees to be retained and all portions of the off-site tree driplines which extend onto the site. No tree toxic materials shall be dumped on the project site (e.g., gasoline, herbicide, salt).
H. No grading (grade cut or fills) shall be allowed within the critical root zone of the on-site trees to be retained and all portions of off-site trees which extend onto the site with the exception of approved encroachment areas on the final development plans. If, in the opinion of the City Arborist, the impact of permitted grading in the critical root zone is severe, then the affected tree shall be retained on site but determined lost, and mitigation as required by the approving body shall be imposed.
I. No trenching shall be allowed within the critical root zone of the on-site trees to be retained and all portions of the off-site tree driplines which extend onto site. If it is absolutely necessary to install underground utilities within the CRZ/dripline of the tree, the utility line shall be bored or drilled under the direct supervision of a certified arborist.
J. Landscaping beneath the on-site trees to be retained and all portions of off-site tree driplines which extend on the site shall be consistent with the irrigation requirements of the protected trees as approved by the City Arborist.
K. Irrigation systems shall be approved by the City Arborist. No trenching for irrigation lines will be permitted under critical root zones without approval by the City Arborist.
L. Prior to installation of new asphalt, weed control chemicals shall not be applied where they can leach into the dripline of any protected tree(s).
M. During construction, the frequency and amount of water for protected trees shall not differ from that received prior to construction, unless otherwise authorized by the City Arborist.
N. Paving within the critical root zone of trees should be stringently minimized and only allowed under approval by the City Arborist. When pavement is absolutely necessary in the determination of the Public Works Director, porous material shall be used, or alternative design solutions may be utilized as approved by the City Arborist.
