Integrated Pest Management Policy and Implementation Guidelines for the City of Orange
The City has an Integrated Pest Management Program (IPM) which focuses on the long-term prevention and/or suppression of pest problems through a combination of techniques including pest identification, monitoring, prevention, and treatment tactics to help maintain landscape and tree health and keeping fields and parks safe and usable for the public. Pests include weeds, invasive species, rodents, and insects. Our IPM is well supervised, regulated and permitted by the Orange County Agricultural Commissioner. Please click here to view the City's IPM Policy and Implementation Guidelines. As part of our IPM, the City may use a variety of pesticides to treat for pests which may include herbicides, rodenticides, insecticides, and fungicides. All products used are approved by the Orange County Agricultural Commissioner and are applied according to the manufacture’s specifications. The type of product and amount used varies, depending on the pest problem and location. Please click here for a potential list of products.
The majority of the spraying in large turf areas is done in the spring time to eliminate broadleaf weeds that displace grass and create clumping and tripping hazards. This work is usually completed by the start of summer (depending weather and other factors). Spot spraying for weeds is done minimally in turf and planters to eliminate weeds and in paved areas to reduce cracks, lifting and other hazards. Playgrounds are not sprayed and mulch is placed around trees and planters to suppress weeds and reduce the use of pesticides. When spraying does occur in parks, signage is put up indicating the area is being sprayed and is closed until dry.

Santiago Hills Park – Pesticide-Free Maintenance Pilot Program
In response to concerns from members of the community regarding pesticide use in city parks, Santiago Hills Park has been selected for a pesticide-free maintenance pilot program starting September 2019. The program will provide pesticide-free maintenance for a minimum of one year. This includes eliminating the use of all pesticides, to include herbicides, rodenticides, and insecticides as part of regular maintenance practices. Over the course of the year, staff will evaluate operational and financial impacts of eliminating pesticides while providing a pesticide-free maintained park for community members who prefer this option. The intent for the pilot program is for it to be a representative of options for future consideration throughout the park system if determined to be safe, functional, and acceptable to the community at-large.
The Santiago Hills Park pesticide-free maintenance pilot program has been in place now for 8 months. During the course of this year long program, staff has been assessing several factors to get a better understanding of the impacts of eliminating the use of pesticides. Factors assessed include the type and percentage of problematic weeds, hardscape conditions, tripping hazards, effects of insects/rodents, and change in appearance (aesthetics). At the end of April 2020, staff conducted a walkthrough to evaluate park conditions and compare the findings to what was documented at the end of last year. Merchants, the City’s contractor, continues to mow, edge, and perform all other tasks contained in the contract specifications. With the large amount of rain over the last couple of months, there has been a significant increase in broadleaf weeds, mainly pink and burr clover. As of April, 80% of the turf now contains some broadleaf weeds. The slope alongside the parking lot has seen an increase of 30% in weeds and there is an increase in weeds in sidewalk cracks. The pink clover continues to bloom during the spring season resulting in more bees being attracted to the area while the burr clover has started to produce prickly “stickers.” Staff anticipate the springtime will continue to bring on a robust growth of all plants and weeds. During the final quarter of the program, the effects of the spring growth will be monitored and documented. If any of these conditions cause safety or accessibility concerns, staff will evaluate steps that can be taken to address the issues.
On December 6th staff did the first quarterly walkthrough to evaluate park conditions and compare the findings to what was documented at the start of the program. Merchants, the City’s contractor, has continued to mow, edge, and perform all other tasks contained in the contract specifications. Conditions noted include an increase from less than 3% of broadleaf weeds (primarily clover) to 50% of the turf area now contains some broadleaf weeds, while some areas as large at 100 square feet or more are completely covered by clover. With this increase however, to the average park patron, the overall appearance of the park has not changed. This is a larger increase in weeds then staff expected. The warm fall temperatures and the early rain are suspected to be a major factor in the increase. Past experience indicates that in the spring time these weeds will proliferate and areas of clover growth will flower, attracting more bees. Other conditions noted in the walk through include an increase in turf damage caused by crows feeding off of worms and grubs, leaf curl caused by Aphids (a type of bug) in newly added plants near the restroom building, and an increase in weeds in sidewalk cracks. Staff will continue to monitor these conditions and address sidewalk weeds with weed-whacking at the surface level. If, over the course of the next several months, these conditions create safety or accessibility issues for park users, staff will evaluate additional steps (at an additional cost) that can be taken to address the concerns (i.e. increase mowing frequency, hand-weeding cracks for a better effort to remove roots, evaluate non-toxic insect/bug repellants, etc.).
