14.04.060 Joshua tree relocation methodology.
(A) A tree spade shall be used to prepare the transplant site and excavate the Joshua tree and root system. Soil profile can influence Joshua tree root mass and should be taken into consideration when selecting tree spade size. General tree spade sizing guidelines as follows:
(1) Forty-two-inch spade for western Joshua trees under one meter in height.
(2) Fifty-four-inch spade for western Joshua trees one to two meters in height.
(3) Ninety-inch spade for western Joshua trees two to four and one-half +/- meters in height.
(B) Joshua trees to be transplanted shall be prepared by creating earthen berms around the perimeter of the tree for pre-soaking operations.
(C) The northern face of each tree shall be marked at the base with spray paint to aid in proper orientation during transplanting. The trees shall be orientated at the receiving site in the same direction as the original location.
(D) Only trees less than or equal to 15 feet in height, and in good condition are recommended for transplanting. Each western Joshua tree that is transplanted shall have tree inventory data collected according to the tree inventory technical specifications.
(E) A water regimen shall be conducted to ensure survivability. All trees shall receive a pre-soaking approximately one week prior to transplanting. Each tree shall have an earthen berm built around the perimeter, large enough to accommodate 20 gallons of water to ensure the root ball will hold together and to minimize transplant shock.
(F) Each tree shall be placed in the receiving hole in the appropriate geographic orientation and backfilled with native or mineral amended soil. The original soil line on the trunk should be slightly higher than adjacent grade to allow the transplanted tree to settle to the appropriate grade. The hole shall be filled with water and the tree will be slightly agitated to dislodge any air bubbles that could create root rot.
(G) Earthen berms shall be created around each tree after transplant to ensure western Joshua trees can receive up to five gallons of water per watering event. Each western Joshua tree will be hand watered (top to bottom) every two weeks for up to six weeks following transplanting. All trees shall be watered for one year: The trees should be watered three times in the spring, one time in the summer, and one time in the fall with three gallons of water per watering event. The proponent must notify the Landscape Superintendent, City Arborist or appointed designee in advance of each watering event to ensure compliance with the watering regimen maintenance period.
(H) A daily pre-transplant operation safety briefing shall be conducted to ensure all applicable safety regulatory requirements have been met. All personnel working in and around equipment shall wear hard hats, reflective safety vests and protective eye wear.
(I) Protection of Public and Private Property. The proponent shall be responsible for the protection of all public and private property and improvements within and adjacent to all work areas including but not limited to: plant material, lawns, sprinkler systems, drains, fencing, block walls, brick or masonry work, sidewalks, street paving, street lights, traffic signals, utility pedestals and all other public or private improvements.
(J) Restitution for Public or Private Property Damage. Any improvements removed or damaged, other than those scheduled for removal shall be replaced in kind at the proponent’s expense to the absolute satisfaction of the Grounds and Green Spaces Superintendent and/or private property owner. Replacement shall take place no later than five working days from the date of damage, unless otherwise authorized by the Grounds and Green Spaces Superintendent.
(K) Underground Service Alert. The proponent shall be responsible for contacting Underground Service Alert, securing a dig-alert ticket, and allowing the time required by law for members to respond and mark their underground infrastructure prior to conducting any western Joshua tree transplanting operations. The proponent shall analyze and respect all utility markings and transplant western Joshua trees with care to avoid contact with any underground infrastructure within the transplant zone. (Ord. 1614 § 4 (Exh. I), 2023; Ord. 1556 § 1, 2020)
14.04.070 Desert vegetation preservation criteria.
All development proposals for land which contains desert vegetation shall be subject to the following provisions regarding the preservation of native desert vegetation both on- and off-site:
(A) The minimum standard of preservation shall be:
(1) Two California junipers per gross acre, averaged for the gross site area covered by the development application; or
(2) Where soil conditions or conditions of the California juniper prohibit the preservation of two trees per acre, or where the total number of healthy trees per gross acre is not equal to two per acre, the minimum standard of preservation will be determined by a desert native plant specialist and confirmed by the City’s Landscape Architect, or in lieu thereof, the Director of Public Works’ designee, in accordance with the following criteria:
(a) Soil characteristics of a proposed area for relocation of vegetation,
(b) Health of the native desert vegetation, including damage to trunk or root system,
(c) Size of the Joshua tree and the location to where the tree will be transplanted,
(d) A suitable top-root ratio;
(3) Where possible, a minimum of two California juniper trees per gross acre shall be retained undisturbed on site. California junipers are valuable components of the native desert vegetation and it is desirable to retain specimens whenever possible. However, California junipers do not transplant well, are large plants which are difficult to incorporate into landscaping and are not readily available as nursery stock;
(4) To enhance the likelihood of survival, native desert vegetation that cannot be fenced and left undisturbed will not be left in place while grading. The options for preserving trees on site after grading are the following:
(a) Move the vegetation slated to remain on site to a holding area. After grading has been completed, move vegetation once again to a permanent location.
(b) Grade in Phases. Ready the area to receive vegetation first, then transplant and complete grading.
(B) The quantity of California junipers calculated under the minimum standard of preservation as determined above shall be preserved by any combination of the following means:
(1) The development proposal shall be prepared in a manner which retains on site those plants that can be incorporated into the design of the development. Development proposals should use native desert vegetation to landscape on-site detention basins, entry statement areas, and other open space sites whenever possible, where xeric landscaping is appropriate;
(a) California junipers retained on site shall be credited toward the two trees per gross acre or other minimum standard of preservation,
(b) Other methods of preservation as shown in subsection (B)(2) shall not apply to California junipers;
(2) Only after all other options are exhausted, proponents may pay an in-lieu fee to the City to fulfill their obligation of preservation of native desert vegetation. The fee will be used to provide partial funding for the maintenance and coordination of the native desert vegetation banks and preserves. The in-lieu fee will be accepted only when preservation of Joshua and/or juniper trees is not possible due to site constraints that preclude the feasible preservation of desert vegetation, and no alternative preservation options remain. When a proponent must pay an in-lieu fee, the fee shall be calculated on the minimum standard of two trees per acre, less any trees preserved by other means. The in-lieu fee amount shall be determined by resolution of the City Council;
(a) Where California junipers are retained on site, they shall be credited toward the minimum standard or two trees per acre. However, where they cannot be retained undisturbed on site, no in-lieu fee is required;
(3) Any native desert vegetation in excess of the minimum standard for preservation may be removed after the public has had the opportunity to transplant native desert vegetation per subsection (B)(2)(a) of this section, and after the native desert vegetation preservation plan and native desert vegetation removal permit has been approved by the City, or, if applicable, after the payment of the in-lieu fee. (Ord. 1556 § 1, 2020; Ord. 952 § 2, 1992. Formerly 14.04.060)
14.04.080 Maintenance requirements.
Upon completion of construction of the development proposal and after final inspection and acceptance by the City, the following standards relative to ongoing maintenance of native desert vegetation shall apply:
(A) Provisions shall be made assuring, at the expense of the proponent of the development, that desert vegetation preserved on site, in landscape easements, or landscape assessment districts are maintained in a healthy condition for a minimum of two growing seasons.
(B) After one year, an inspection and evaluation of desert vegetation retained on site will be performed by a desert native plant expert, at the expense of the proponent of the development. Based upon this evaluation, if it is determined that any quantity of desert vegetation has died, it will be the responsibility of the proponent to provide replacement desert vegetation as determined by the City Landscape Architect, or in lieu thereof, the Director of Public Works’ designee.
(C) The Director shall require posting of a bond or other appropriate security at the time of development proposal approval to assure maintenance of on-site trees, or trees in landscape easements or assessment districts, for a period of two years. If the project is otherwise required to have a bond posted for landscape maintenance requirements, this requirement shall be incorporated into the same bond. (Ord. 1614 § 4 (Exh. I), 2023; Ord. 1556 § 1, 2020; Ord. 952 § 2, 1992. Formerly 14.04.070)
14.04.090 Unlawful activities prohibited.
(A) Except as provided in this chapter, it is unlawful for any person to damage any desert vegetation as defined in this code.
(B) It is unlawful for any person to falsify any oral statement, paper or document issued to give permission for any person to remove desert vegetation or fail to comply with all conditions or stipulations of this chapter. (Ord. 1556 § 1, 2020; Ord. 952 § 2, 1992. Formerly 14.04.100)
14.04.100 Violation – Penalty.
Penalties for violations of this chapter shall be as specified in Chapter 1.12 PMC.
(A) In addition to other penalties imposed by this code, any person, company, organization, firm or corporation shall be required to replace any damaged, illegally cut, destroyed, killed, removed, mutilated or harvested California junipers, or other desert vegetation pursuant to the recommendation of an authorized desert native plant specialist, to be retained at the expense of the violator. Such specialist shall determine the appropriate number, size, species, location and make written recommendations regarding the replacement of said trees or other desert vegetation. Replacement shall be in sufficient quantities to revegetate the illegally disturbed area either on site or off site within six months of adjudication.
(B) Should the person, company, organization, firm or corporation who committed the violation fail to replace the damaged, cut, destroyed, killed, removed, mutilated or harvested desert vegetation within six months after adjudication, the City may contract to have such plants replaced and the violator shall be charged the replacement costs. Said costs may be placed as a lien on real property. (Ord. 1556 § 1, 2020; Ord. 952 § 2, 1992. Formerly 14.04.110)
14.04.110 Compliance with other laws and regulations.
Nothing in the provisions of this chapter shall relieve nor be interpreted to exempt a proponent of a development proposal from complying with the requirements of the California Desert Native Plants Act, Food and Agricultural Code Section 80001, et seq., and/or any applicable federal laws and regulations. Nor shall any provision of this chapter be construed so as to conflict with, duplicate, or otherwise interfere with general law preemptive of local regulation. (Ord. 1556 § 1, 2020; Ord. 952 § 2, 1992. Formerly 14.04.120)
