UPDATE October 4, 2021   


In 2015, the Santiago Hills Landscape Assessment District (SHAD) residents voted to increase  their assessment in order to maintain, repair, and renovate community landscaping over time.   This is referred to as Landscape Maintenance District 15-1 (LMD 15-1).  The project represents   a long-term Capital Improvement effort to re-landscape SHAD as funding accumulated beyond  what is needed for ongoing maintenance.  Funds are utilized based on community input and  prioritization for landscape renovation to replace plants, shrubs, and irrigation beyond their useful  life.   Included is a map of the District and completed projects to date are noted in blue.   

Fiscal Year 2022 (FY22) Capital Improvement Program  

The Fiscal Year 2022 (FY22) Capital Improvement Program includes renovation of corners at   White Oak Ridge and Newport Boulevard and the small median on White Oak Ridge (noted on  the attached map in light orange). As project budget allows, design will include alternates for  parkways from Newport to Trails End (noted on the map in dark orange). This renovation project  will maintain the landscape palette installed at preceding renovated areas in SHAD and will   incorporate overall renovation goals for District landscaping. These goals include an overall  reduction of turf while maintaining sufficient turf area for pets and aesthetic continuity, irrigation   improvements which meet the State Mandate for Water Efficient Landscapes, and removal and  replacement of pepper trees with more appropriate tree species where possible. Renovations  would also consist of establishing ground cover in select and narrow planting areas, installing  mulch in root-bound areas and at the base of trees, and applying appropriate planting and surface  treatment in parkway planter areas which will include the use of turf in select areas with a minimum   width of 30 inches. The design for the project will be put out to bid this fall, with construction starting late spring 2022, and completion of the project is expected by end of summer 2022.  

Next Steps  

The SHAD Capital Improvement funds will need to be replenished following completion of this   project and, as a result, a renovation project is not being scheduled in Fiscal Year 2023. Once  sufficient funds are available to continue with the remaining original landscape renovation,   homeowners will be invited to prioritize additional landscape renovation projects.  The attached map provides an outline of potential areas for future renovation (noted in green).       


March 11, 2021 - IPM Survey Results

In February, the City solicited input from District homeowners regarding interest in maintaining the current Integrated Pest Management (IPM) Program or evaluating an increase to assessment fees in order to transition to an organics only IPM as part of the new landscape maintenance agreement, which is expected to start in July 2021. A letter, dated February 9, was mailed to all District homeowners. An email regarding the letter was also sent to the Landscape Assessment email distribution list. The information was posted on the District’s page on the City’s website, and notification of the update was sent through the NextDoor app. Homeowners were asked to submit input through an online survey (Survey Monkey), via email, or mailing back their input.

The City received a total of 204 survey responses, of which 85% responding support maintaining the current IPM. A total of 12% of respondents would like to evaluate the option to increase assessment fees to transition to an organics only IPM.  The remaining 3% either selected both or did not make a selection.

At the April 13, 2021 City Council meeting, Council will be presented the award for the new landscape agreement, with the recommendation of maintaining the current IPM, consistent with community input received. Once posted, the staff report for the agreement can be found here:  The current IPM is a holistic approach to sustainable landscape maintenance, focusing on managing insects, plant disease, rodents, and weeds through a combination of proper and timely maintenance techniques (i.e. water management, soil fertility management, and proper pruning and trimming). Application of pesticides is utilized as needed to achieve the standard outlined in the scope of work. Staff pre-approves all chemical applications and the City complies with all local, state, and federal laws and regulations. A licensed, contracted pest control operator holding a Qualified Applicator License (QAL) applies any chemicals for pest control as necessary. Before spraying occurs, staff place additional signage in the areas that will be treated. 

Additionally, as noted in the February correspondence, the recommendation will include implementing the Consumer Price Index assessment not to exceed 3% annually for Overlay District Assessment No. 15-1 in order to sustain standard landscape maintenance (utilizing the current IPM) and capital improvement projects. The annual public hearing required to provide for the annual levy and collection of assessments for the District is set for the Tuesday, June 8th City Council meeting. Once posted, the agenda and information regarding participation can be found here:

Of those who provided comments with their response, respondents in favor of maintaining the current IPM noted several reasons for their input.  The majority noted they opposed an increase to their assessment while others stated that the cost of an organics only IPM is too expensive.  Several respondents also noted that they want to keep the landscaping as it is, and to continue using the current IPM.

Comments from those in favor of evaluating the option to increase the assessment to transition to an organics only option posed follow up questions including concerns about not being able to view all proposals received and the option of going completely pesticide free, similar to how Santiago Hills Park is maintained.  The City will make public the responses to requests for proposals at the time the contract is presented to the awarding authority (in this case, the City Council).  If a winning proposer has access to the specific details of other competing proposals, then the City is greatly impaired in its ability to negotiate and secure the best possible deal on its constituents’ behalf.  Thus, the City’s interest in keeping these proposals confidential outweighs the public’s interest in disclosure until negotiations with the winning proposer are complete and, therefore, we were unable to share the proposals in advance.

The City did evaluate a pesticide free option, however, due to the labor associated with weeding, the cost to implement this option was not sustainable.  While Santiago Hills Park is maintained pesticide free, the park is approximately 90% turf and 10% planters. The weeds currently growing within the turf are maintained similarly to turf maintenance (i.e. mowed) and provide an adequate green ground cover.  Due to the small percentage of planters, the cost savings from applying pesticides is used to provide additional manual labor to remove the weeds from the planters. Conversely, the landscape in the District has a significant amount of planters, which would require an increase in services for manual weeding. As a result, the money saved by ceasing pesticide applications would not be enough to fund the manual weeding needed throughout the District.

Attached is a summary of the results of the input received, as well as a complete list of comments.  We thank you for your feedback. For questions or comments, please email or call the Community Services Department at 714-744-7274.

Santiago Hills Assessment District Landscape Maintenance Update-February 2021

The current landscape maintenance agreement for the District will expire in June 2021.  The City issued a Request for Proposals (RFP) for a new 4-year term, starting in July 2021 through June 2025. The scope of work includes general maintenance of the landscape, mowing, trimming and implementing the City’s approved Integrated Pest Management Program (IPM).

The IPM focuses on the long-term prevention and/or suppression of pest problems (such as insects, invasive species, rodents, and weeds) through a combination of techniques which includes pest identification, monitoring, prevention, and treatment tactics.  The IPM is regulated and permitted by the Orange County Agricultural Commissioner and utilizes products approved by the Environmental Protection Agency (EPA), which may include synthetic pesticides. To view the City's IPM Policy and Implementation Guidelines, please visit:

At the request of some District community members, the RFP included an option to replace EPA approved pesticides with use of organic pesticides only, recommended by the nonprofit organization Organic Materials Review Institute. This option would continue to use a variety of techniques to focus on the long-term prevention and/or suppression of pest problems, including the use of increased manual labor.

To view the full RFP, please visit:

The proposed cost to continue with the current IPM for the new 4 year agreement is approximately 14% higher than the current agreement and with current assessment fees is financially sustainable through the life of the contract. The organics only IPM, on average, costs 50% more. Budget projections indicate the organic only program is sustainable for the first two years of the agreement. To maintain the use of organics only for the remainder of the agreement, an increase of approximately 45% in assessment fees would be required. The current assessment would need to be increased from the existing range of $394-$613 to approximately $566-856 annually (The figures are current estimates. If an assessment increase is pursued, the true increase would be determined through a contracted independent study.) Factors affecting the cost of the IPM include cost of the product, frequency applied, and labor involved in implementing the IPM.  Both programs require the Consumer Price Index (CPI) of 2-3% annually for Overlay District Assessment No.15-1 in order to continue with standard landscape maintenance and capital improvement projects.  Please click here to see a detailed chart comparing the current IPM and the organics only program, including how each program will be implemented and expected results.
