City of La Quinta:
• Planting on Holes 1, 2, 17 & 18 will be completed this week. Next, the crew will perform the final cleaning, weeding, application of weed pre-emergent, and polymer application.
• Trimming of the eucalyptus trees is complete. Ten trees that were uprooted during our most recent wind storm were also removed. No decision has yet been made regarding requests by homeowners willing to pay to have trees removed that are not covered in the perimeter project.
• Trilogy La Quinta has passed all routine compliance inspections by Southern California Air Quality Management District and the City of La Quinta for our dust control mitigation efforts.
• Irrigation is going in on Holes 6 and 7. Planting will follow, with completion by the end of May. Holes 8 and 9 are next on the schedule for irrigation and planting.
Homeowner Reminder and Notice
Pool service providers are still draining pool water onto the golf course perimeter, causing severe slope erosion that requires repair to areas that have already been finalized. PLEASE ADVISE your pool service vendor and your landscaper not to flush water off your property onto the perimeter.
Landscaping on Holes 1,2, 10, 17 and 18 is largely complete. One plant species – Dalea Greggii – has been out of stock at the nursery, but is scheduled for planting late next week. Planting will continue through the summer until the whole project is complete.
Eucalyptus trees on Holes 3, 6, 8 and 9 are scheduled for trimming next week. That completes tree trimming for the entire perimeter. Those trees will be scheduled for trimming again in two years.
April windstorms have caused us to modify the work plan in certain locations. Since Holes 8 and 9 are already treated with a polymer and are in the most wind-prone area, it was decided to delay irrigation and planting until winds subside. Irrigation and planting will begin on Holes 6 and 7 instead.
Polymer stabilization has been delayed while the contractor uses two water wagons full time to mitigate dust issues caused by 50 to 60 mile per hour winds. Polymer stabilization is being applied to the left side of Hole 2 and the right side of Hole 10 this week as a test to determine how well the process will work in planted areas. If the test goes well, a polymer will be applied upon completion of each hole.
Questions were raised regarding the burying of mulch on the golf course perimeter. Petra Geosciences was retained to assess the situation and make a professional determination. Their findings are as follows:
Conclusions and Recommendation
Based on our experience, observations, and conversations with Mr. Ron Englhard, it is our opinion that the activities of burying the mulching residue onsite are not expected to pose a threat to the existing homes.
Further, burial of the mulching residue can continue providing that residue disposal pits are no closer than 15 feet from the closest residential property line and the depth is no more than 4 feet.
Although there are no developments planned for the burial areas discussed in this report, please note that buried organic material will decompose over time resulting in surface subsidence. Accordingly, the residue disposal pits are not suitable for support of buildings, structures or flatwork. As such, we suggest that you consider having the locations of residue disposal pits surveyed and the data kept for future use if development of the golf course is considered.
The areas of the residue disposal have been surveyed and kept with the project documentation.
Damage to Perimeter
There continues to be a handful of incidents of homeowners discharging pool water or dumping yard waste onto the golf course perimeter. Any damage caused by soil erosion will be repaired, waste will be removed and the property owner will be billed for the costs.
Plant material, mulch, and grinding debris has been completely removed from the golf course. The leftover material has been moved to an area behind #15 and is being moved offsite through the back gate to a licensed disposal facility.
A polymer has been applied to 37 acres. The remaining 11 acres are now in the process of being covered. Those golf holes where plants are already being installed will have polymer applied once the planting is complete.
Irrigation and Planting:
Installation of irrigation lines is complete on #1, #17, #18, and #2 fairway and tee. Next on the schedule are #10, #8 and #9 in that order. Planting is in progress on #18 along Trilogy Parkway. Next on the schedule are #1, right side of #18, #2 and #17 in that order.
-The TLQMA Board approved the trimming of Eucalyptus trees in the perimeter. Holes #1, #2, #10, #17, and #18 have been trimmed. These trees were not trimmed during the original clearing process by Pro-Turf.
-Homeowners with pools or water features are reminded that discharging water onto the perimeter landscape area is not permitted. Homeowners are responsible for the repair of erosion caused by runoff from your property.
Recently, a significant number of pool owners in the community flushed large amounts of water from their pool equipment down into the perimeter landscape areas. Please be advised that this is not permitted as flushing the pool down the hillside sends mud down into the turf, which damages the contour of the perimeter landscape areas.
We encourage homeowners to communicate this information with your pool service vendors to prevent this from occurring, damaging the perimeter landscape area and golf course. If pools need to be drained or water removed from the pool equipment please be sure to follow the La Quinta ordinance and notify both the City and Maintenance Association in advance.
Those in violation of the ordinance or caused damage may be responsible for the cost of repairs. Thank you for your cooperation as we continue to make progress on the perimeter landscape.
The last “On The Perimeter” stated that in response to complaints to the Air Quality Management District, a comprehensive plan for dust control was developed. This plan included the application of a polymer sealant for those areas that are not being actively worked on and increasing watering for those areas that are being actively worked on installing the irrigation system and plants. The plan was submitted to the City of La Quinta and was accepted and we received the Public Works Permit for the PM-10 Dust Control Plan.
Due to continued complaints to the city from Trilogy residents, the La Quinta Building Department is now requiring a landscape permit and has stopped all work on the project with the exception of dust control and maintenance. The landscape plan has been submitted to the city, but the plan must also include approval from the Coachella Valley Water District. The CVWD application is very specific regarding format. Work is now underway to put the plan into their required format. This process is expected to take as long as two weeks. In the meantime, no installation work can be done on the project.
A viable solution to the problem of the ground material and plant material that has not been ground, as well as the remaining debris piles have been found. A company that specializes in removing unwanted material from job sites and taking this material to licensed processing sites has toured our facility and has quoted a very reasonable cost for removing the material. Our contractor, PTI, has agreed that offsite disposal is the most cost-effective and beneficial way forward and has started to do the preliminary necessary work to accomplish this. The city has approved performing this work while the landscape permit is being obtained. PTI will be able to keep its workforce intact doing this work during the waiting period. The material removal will be started next week.
We will continue to keep you informed of the progress on the permits as well as the unwanted material removal. Thank you for your patience and support.
The cleaning process has been completed on the following holes: 13, 14, 15, and 16. We are continuing clean up this week on holes 11 and 12, which is projected to be completed by February 3.
The subcontractor responsible for grinding up the remaining vegetation will be on site in early February and will grind the acacia pile located on holes 14, 16, and 15. A soil engineer has reviewed the current bury pit program and provided guidance on current and future bury pits. The burying of clean up piles on hole 3 has resumed.
Air Quality Management District
The Air Quality Management District (AQMD) has recently received calls regarding the smoke and dust near our community. Please be advised the smoke, ash, and smell from the burning is not created by us but comes from the farm next door and the AQMD has no jurisdiction over it because it is tribal land.
In response to the AQMD, we have developed a comprehensive plan for dust control. We have increased our dust control efforts with additional watering and have purchased a polymer application which is currently being applied throughout the golf course.
Thank you for your patience and support as we continue to make progress on the perimeter landscape.
The removal process of unground material on hole 3, 6, and 7 has been completed. Piles continue to be removed and transported to the grinding location near hole 15. Piles along the lake on hole 13 and hole 18 will be consolidated near hole 14 as well as the piles of ground material on hole 2 will be moved to hole 8.
The cleaning and clearing process will continue over the next week in areas around hole 4, 15, 14, 13, 12, and 11. A grinding subcontractor will be providing us with a date to grind piles on holes 14 and 16 as well as piles on hole 15 sometime in the near future. Any items considered to be buried will wait for approval by a soil engineer prior to
Thank you for your patience and support as we continue to make progress on the perimeter landscape.
The removal process began for the piles of acacia behind 10 green. The piles are being transported to the grinding location next to the 15th tee. Once those are finished, the piles on hole 3 will be removed and transported, rather than grinding them in place.
The cleaning process on hole 7 will be completed this week. After completion, the cleaning crew will proceed to holes 6, 5, and 4.
Prior to installing the new irrigation, the landscape architect will review the holes in Phase 1 in order to determine which remaining plants will stay and which will be removed.
Thank you for your support and patience.
The consolidation piles at the 2nd tee and 2nd green have been ground this week. The piles on the 3rd tee and 6th tee were also ground at the 2nd green. The consolidation pile near the 17th tee was additionally ground. The contractor is doing the final clearing on holes 8 and 9 this week before Christmas. Irrigation installation on Desert Willow will be nearly complete this week as well. The pile near the 4th green has also been removed.
Upon their return in January, grinding on the 10th hole and the 3rd hole will be started. Planting will also be started on Desert Willow near hole 18th tee. The contractors will be trying to subcontract additional grinding work in January in order to clear all areas as quickly as possible.
Final cleaning and grading work on the entire 18th and 1st holes have been completed. Irrigation installation has started on the Trilogy Parkway side of the 18th hole as well as on desert Willow behind the 18th tee. As soon as the irrigation work is completed, planting will begin. The 1st hole irrigation and planting will follow this work. Planting of fragile plants susceptible to frost damage will be put off until after January 15.
Final clearing, grading and consolidation pile grinding on hole 10 is currently being done. Consolidation pile grinding on hole 2 will start after the grinding on 10 is completed. Final clearing and grading of hole 9 will follow hole 10. Our contractor PTI is currently investigating the feasibility of adding a second grinder to the project.
PTI will start using the water wagon when available to spray specific perimeter locations for dust control in the mornings in addition to areas where grinding occurs. Several homeowners have been wetting down their perimeter using their impulse sprinklers. This is greatly appreciated.
A list of homeowner’s tree requests has been compiled. Our architect will be evaluating these requests as to whether each tree is important from a safety or compatibility standpoint. The PLA Committee will be contacting those homeowners that have requested tree removal with the results of our architect’s findings.
The grinding work of the debris piles next to 15 tees continue this week. With the strength of the current Santa Ana winds, work will stay at 15 tees until the winds subside. Grinding of the consolidation piles in Phase 1 on holes 18 and 2 will start when the winds subside. Final clearing on 18 along Trilogy Parkway is also being completed at this time.
Grading on Desert Willow behind the 18th tee has been completed. Initial plant layout and irrigation installation has started along Trilogy Parkway from the Trilogy entrance to Desert Willow. Upon completion of this area, work will begin on hole 1.
Additional dust control measures are being evaluated besides utilizing the golf course sprinkler system. The results from these evaluation will be reported in On The Perimeter as soon as available.
Thank you for your support and patience.
June 6, 2018
We have made an increase to the irrigation for shrubs. Shrub beds are now being watered four three times a day for seven minutes each time. Start times for shrubs are 2 am, 6 am, 5 pm, and 9 pm. This will be the last irrigation time increase for shrubs. The lawns are being watered four times a day for three minutes each time. Start times are 5 am, 6 pm, 10 pm, and 1 am.
We are in the final stretch of trimming back the Texas Rangers. The goal is to cut them back to a lower height and a more natural look. These are the shrubs that grow purple and there are many throughout the community, some are located under window sills and in hedges. Once they are trimmed, the shrubs will look woody, but with the warm weather, they will grow back and look better. The overall goal of trimming back plants is to renovate them and keep them looking natural. Plants get woody over time and this is a way to remedy that. When the Texas Rangers are complete, we will start trimming the oleanders that are too high and woody. We would like to maintain the oleander with selective trimming.
June is the month to begin trimming the fan palms. We will inform you when we begin the trimming sometime this month. We have received work orders for trimming palms; however, we will first complete the street trimming. In addition, palms need to be fully bloomed in order to be trimmed. If they are trimmed too early, there is a risk the bloom will come back.
If you have any questions or concerns, please call Mirna Aceves, Landscape Specialist (760) 702-3017. For after-hours landscaping/irrigation concerns, please call Customer Care (800) 428-5588.
Each week our landscape contractor fields multiple crews that maintain Trilogy’s common areas. The crew rotations shown here are the normal day-in and day-out assignments. Holidays and special events may cause these crew assignments to change.
One use of this information is to be able to anticipate when there may be landscape activities (debris piles, motor noises, dust) that could effect your at-home plans.
