Executive Summary Residents have raised concerns about speeding and traffic safety at the intersections of Batiquitos Drive and Aviara Drive, La Costa Avenue and Camino De Los Coches, and Tamarack Avenue and Sunnyhill Drive. They have also requested the installation of all-way stop control at these three intersections. In response to the requests, all-way stop analysis was performed for each of the three intersections in accordance with the guidelines found in the California Manual on Uniform Traffic Control Devices, or CA MUTCD. Based on the analysis performed, these intersections satisfied at least one of the all-way stop criteria to justify consideration of all-way stop control. Staff recommend the installation of all-way stop control at the intersections of Tamarack Avenue and Sunnyhill Drive, La Costa Avenue and Camino De Los Coches and Batiquitos Drive and Aviara Drive to enhance traffic safety. Explanation & Analysis Multi-Way Stop Analysis All-way stop analysis, in accordance with the guidelines found in the CA MUTCD, considers vehicular, pedestrian and bike volumes as well as other factors such as collision history, sight distance, movement conflicts and traffic operations to determine if all-way stop control is TRAFFIC SAFETY & MOBILITY COMMISSION May 4, 2026 Item #2 Page 1 of 17 justified at a particular intersection. The analysis conducted by staff is structured around the following four primary criteria and four optional criteria: Criteria A of the CA MUTCD multi-way stop criteria allows consideration of a multi-way stop as an interim measure prior to installation of a traffic signal. Criteria B allows for consideration of a multi-way stop when there have been five or more reported collisions within a 12-month period that are susceptible to correction by a multi-way stop. Criteria C evaluates the traffic volumes to determine if a multi-way stop can be considered. Criteria C is satisfied if: 1) The vehicle volume entering the intersection from the major street, total of both approaches averages at least 300 vehicles per hour for any eight hours of an average day; and 2) The combined vehicular, pedestrian and bicycle volumes entering the intersection from the minor street, averages at least 200 units per hour for the same eight hours with an average delay to minor street vehicular traffic of at least 30 seconds per vehicle during the highest hour. 3) If the 85th-percentile approach speed of the major-street traffic exceeds 40 mph, the minimum vehicular volume warrants are 70% of the values provided in Part 1 and 2. Criteria D allows consideration of a multi-way stop where no single criterion is satisfied but where Criteria B and C are satisfied to 80% of the minimum values. Optional Criteria In addition to the four criteria listed above, the CA MUTCD includes optional criteria which also can be considered. The optional criteria are described as: A. The need to control left-turn conflicts; B. The need to control vehicle/pedestrian conflicts near locations that generate high pedestrian volumes; C. Locations where a road user, after stopping cannot see conflicting traffic and is not able to negotiate the intersection unless conflicting cross traffic is also required to stop; and D. An intersection of two residential neighborhood collector (through) streets of similar design and operating characteristics where all-way stop control would improve traffic operational characteristics of the intersection. Analysis Results Staff evaluated the subject three intersections in accordance with the guidelines mentioned above. Based on the analysis results, each of these locations has satisfied at least one of the criteria for all-way stop consideration. Table 1 summarizes the analysis results, and the CA MUTCD work sheets are provided in Exhibits 2, 3 and 4. May 4, 2026 Item #2 Page 2 of 17 Table 1: Multi-way Stop Analysis Results Summary INTERSECTION Criteria A B C D Optional Interim Measure Collision History Traffic Volumes Satisfy 80% of Criteria B & C A Left- turn Conflicts B Vehicle & Pedestrian Conflicts C Sight Distance D Neighborhood Collector Streets Batiquitos Drive and Aviara Drive No No No No No Yes No No La Costa Avenue and Camino De Los Coches No No Yes No No Yes No No Tamarack Avenue and Sunnyhill Drive No No No No No Yes No No The following sections provide further explanation for the criteria each intersection satisfied. Intersection of Batiquitos Drive and Aviara Drive Batiquitos Drive and Aviara Drive are both classified as Local/Neighboring Streets in the General Plan Mobility Element and are located within southwest quadrant of the city, see Exhibit 1. Batiquitos Drive is a two-lane road with a striped median and an approximately curb-to-curb width of 46 feet. Bike lanes are provided on both sides of Batiquitos Drive and no on-street parking is permitted. It has a posted speed limit of 40 mph. This segment of Batiquitos Drive runs in an east–west direction. There is an uncontrolled marked crosswalk enhanced with Rectangular Rapid Flashing Beacons, or RRFBs, crossing Batiquitos Drive on the west leg of the intersection for pedestrians accessing the Aviara Golf Club and the Batiquitos Lagoon trail to the south. Aviara Drive is a two-lane roadway with parking permitted in both directions. It has a roadway width of 40 feet. Aviara Drive runs in a north-south direction terminating at Batiquitos Drive where it meets the driveway for the Aviara Golf Club. Both Aviara Drive and the golf club driveway are controlled by a STOP sign at this intersection. City staff have received concerns regarding speeding and safety at this intersection, along with requests to install all-way stop control. In response to these requests, traffic data was collected on February 4, 2026, for an all-way stop analysis. The collected counts indicate that 221 pedestrians used the intersection over the course of a typical day. With access to the trail and the Aviara Golf Club, installation of an all-way stop control at this intersection would help reduce conflicts between vehicles and pedestrians, thereby satisfying Optional Criterial B. Therefore, staff recommend implementing an all-way stop at the intersection of Batiquitos Drive and Aviara Drive. With the installation of an all-way stop, the existing RRFBs will be removed as RRFBs are warning devices and are not allowed at controlled crosswalk location per CA MUTCD. Intersection of La Costa Avenue and Camino De Los Coches La Costa Avenue and Camino De Los Coches are both classified as Neighborhood Connector Streets in the General Plan Mobility Element and are located within the city’s southeast May 4, 2026 Item #2 Page 3 of 17 quadrant, see Exhibit 1. La Costa Avenue runs in an east–west direction and Camino De Los Coches intersects it at a T-intersection currently controlled by a STOP sign. West of Camino De Los Coches, La Costa Avenue is a four-lane road with a striped median and an approximately curb-to-curb width of 64 feet. East of the intersection, between Camino De Los Coches and Circulo Sequoia, it’s a two-lane road with an intermittent raised median. It has a curb-to-curb width ranging from 40 feet to 64 feet. The posted speed limit west of Camino De Los Coches is 45 mph and reduced to 35 mph east of the intersection. Bike lanes are provided on both sides of La Costa Avenue and no on-street parking is permitted. Camino De Los Coches is a two-lane roadway with a striped median. It has a consistent roadway width of 64 feet and a posted speed limit of 40 mph. Bike lanes are also provided on both sides of Camino De Los Coches and no on-street parking is permitted. City staff have received concerns regarding safety at this intersection, along with requests for an all-way stop. In response to these requests, traffic data was collected on August 23, 2025, for the all-way stop analysis. During the peak eight-hour period, an average of 323 vehicles entered the intersection from La Costa Avenue, while a combined total of 177 vehicles, pedestrians and bicyclists entered from Camino De Los Coches over the same eight-hour period. The 85th percentile speeds on La Costa Avenue were recorded at 45 mph eastbound and 42 mph westbound. Under Criteria B, Part 3, when the 85th percentile speed on the major street exceeds 40 mph, the minimum volume thresholds may be reduced to 70%. Since the measured 85th percentile speeds exceed 40 mph on La Costa Avenue, this intersection qualifies for evaluation under the reduced thresholds. This adjustment results in minimum volume requirements of 210 vehicles on the major street, La Costa Avenue, and 140 units on the minor street, Camino De Los Coches. Based on the collected data, the intersection of La Costa Avenue and Camino De Los Coches satisfies Criteria C for consideration of all-way stop control. Additionally, this intersection is in proximity to the La Costa Town Square, La Costa Canyon High School, Stagecoach Community Park and a church, facilities that generate high bicyclists and pedestrian activities. Traffic counts indicate that 115 bicyclists and 252 pedestrians used the intersection over the course of a typical day. Implementing all-way stop control would help reduce conflicts between vehicles, pedestrians and bicyclists, thereby satisfying Optional Criterial B. Based on these findings, staff recommend installation of all-way stop control at the intersection of La Costa Avenue and Camino De Los Coches. Intersection of Tamarack Avenue and Sunnyhill Drive Tamarack Avenue and Sunnyhill Drive are designated as a Neighborhood Connector Streets in the General Plan Mobility Element. The intersection is located in the city’s northwest quadrant, see Exhibit 1. The posted speed limit on Tamarack Avenue is 30 mph, whereas Sunnyhill Drive carries a prima facie speed limit of 25 mph. The surrounding land uses is primarily residential with schools nearby. The intersection is side-street stop-controlled on Sunnyhill Drive with a raised crosswalk enhanced with RRFBs on the east leg crossing Tamarack Avenue. Tamarack Avenue has a May 4, 2026 Item #2 Page 4 of 17 roadway width of 48 feet from curb-to-curb, accommodating a travel lane and bike lane in each direction. On-street parking is not permitted in the vicinity of the intersection. Sunnyhill Drive has a roadway width of ranging from 30 to 40 feet accommodating one travel lane and on- street parking in each direction. Following a bike collision in September 2025, staff received a request to install an all-way stop to enhance safety at this intersection. In response to the request, an all-way stop analysis was performed and traffic counts were collected on October 28, 2025. The collected counts indicate relatively high number of bicyclists and pedestrians, 162 bicyclists and 187 pedestrians, used the intersection over the course of a typical day. Field observations further reveal that many of the bicyclists and pedestrians were students traveling to and from nearby schools during school drop-off and pick-up periods. Consistent with the guidelines in the California MUTCD, pedestrian and bicycle volumes may be considered when evaluating the need for all-way stop control, particularly where they contribute to increased conflicts with vehicles. Installing an all-way stop is expected to enhance safety by reducing vehicle speeds, clarifying right-of-way, and providing more consistent crossing opportunities for pedestrians. Based on these factors, staff recommend implementing all-way stop control at the intersection of Tamarack Avenue and Sunnyhill Drive as it satisfies Optional Criterial B. According to the CA MUTCD, RRFBs are warning devices and are not allowed at controlled crosswalk locations, including stop-controlled crosswalks. As such, the existing RRFBs will be removed concurrently with the installation of an all-way stop at Tamarack Avenue and Sunnyhill Drive. The raised crosswalk previously installed to manage speed on Tamarack Avenue will also be removed as vehicles will be required to stop at this intersection with the all-way stop. Community Outreach Staff have notified affected residents, business owners and others who may be interested in the installation of an all-way stop at the subject three intersections. Correspondence received is provided in Exhibit 5. • Doorhangers to residents and property owners adjacent to the intersections • Email to property management company of apartments in the vicinity • City Manager’s Update e-newsletter • Updates Nextdoor Recommendation Based on the findings presented in this report, which are consistent with the criteria described in the CA MUTCD, staff recommend the installation of all-way stop control at the intersections of Batiquitos Drive and Aviara Drive, La Costa Avenue and Camino De Los Coches, and Tamarack Avenue and Sunnyhill Drive. Next Steps Upon receiving support from the Traffic Safety & Mobility Commission, staff will introduce ordinances to establish all-way stop control at the intersections of Batiquitos Drive and Aviara Drive, La Costa Avenue and Camino De Los Coches, and Tamarack Avenue and Sunnyhill Drive for City Council’s adoption. May 4, 2026 Item #2 Page 5 of 17 Once the ordinances are adopted, staff will move forward with the implementation of STOP signs and associated pavement markings at these intersections. High visibility crosswalk markings will be installed along with the all-way stop control. The existing RRFBs at the Tamarack Avenue and Batiquitos Drive intersections as well as the raised crosswalk on Tamarack Avenue at Sunnyhill Drive will be removed concurrently with the installation of all- way stop control.

As a resident of Carlsbad and someone that lives close to this intersection and drives through it each day, I agree that having a stop sign at this location would be an improvement- the challenges that you mentioned in your flyer ( making it easier for cars to turn, reducing speeds, and improving pedestrian access) would all be improved with this stop sign. Thanks for your time. Ben Rubenson CAUTION: Do not open attachments or click on links unless you recognize the sender and know the content is safe.

I will be out of town so here are my comments. The only time of the day where this could be an issue is when school let's out at La Costa Canyon HS. 3:00-3:30. The rest of the day most traffic is East and West on La Costa. (Most people turning from Los Coaches to westward La Costa roll through the stop. Police enforcement should be increased) Installing an all way stop would adversely affect traffic for 23 hours each day. It already takes 15 minutes to get to the freeway from La Costa Oaks due to increased traffic, lane and speed limit reductions. What is the problem you're trying to solve and is it significant enough to affect traffic all day? Jim Hissong Carlsbad Resident.

We have lived at the address below since 2000. Our home is about 0.25 miles from the subject intersecƟon. We support the proposal to add an all-way stop at this intersecƟon. In or about 2010, the City of Carlsbad increased the speed limit on BaƟquitos Drive from 35mph to 40mph from Aviara Parkway to Golden Star Lane. The speed limit from Poinseƫa Lane to Golden Star was also increased from 40mph to 45mph. We were disappointed by The City’s decision because we felt that many drivers would ignore the posted speed limits and it would be dangerous to the many residents and hotel guests who walk on and across BaƟquitos Drive. Our worst fears were realized. We applauded The City’s decision to reduce the speed limit from Poinseƫa to Golden Star several years later however the speed problem persists today. We have observed limited to no speed enforcement on BaƟquitos Drive over the past ~26 years For those who are unfamiliar with this part of Carlsbad, BaƟquitos Drive has become a convenient “cut-through” for those traveling from Poinseƫa Lane to El Camino Real. The numerous traffic signals and heavier traffic counts on the arterial streets, Poinseƫa and Aviara Parkway, make BaƟquitos a quicker way to reach El Camino Real, even if one were to observe the posted speed limit. It is quite surprising that the 40mph speed limit on Aviara Parkway, a 4 lane road with a conƟnuous raised median is the same as the speed limit on BaƟquitos Drive, a 2 lane street with effecƟvely no median and terrain and curves that create limited visibility in several areas. We were never informed as to the raƟonale for the speed limit changes on BaƟquitos Drive. We simply concluded that the traffic engineers and/or consultants who worked on this maƩer neither lived in this secƟon of Aviara nor did they have family that lived here. We are pleased that The City is focusing on our neighborhood once again. As a result, we would also support a review of the speed limit on BaƟquitos Drive in addiƟon to the placement of an all- way stop at Aviara Drive.

Ave And Sunnyhill Dr. Hello, My name is Nicholas Houts. I live at 4043 Sunnyhill Drive. I am for the All-Way Stop at the Intersections of Tamarack Avenue and Sunnyhill Drive. I have lived on Sunnyhill for 29 years, so I am very familiar with this intersection. Over the last few years, I have noticed that the traffic on Tamarack has increased dramatically. When the City installed the raised crosswalk/speed hump on the east side of the intersection, I wondered why not an All-Way-Stop instead. Since the raised crosswalk was installed, my family and I have been frustrated with this intersection to the point that we have to stop walking southbound on Sunnyhill Drive to cross the street. Also, we avoid using the intersection to make a left turn onto Tamarack from the north side of Sunnyhill Dr., as traffic is too unpredictable due to limited visibility and the speed of east-west traffic on Tamarack. I believe that making this intersection an All-Way Stop would increase safety for both pedestrians and drivers. Along with slowing down vehicles traveling on Tamarack Ave. and Sunnyhill Drive. Thank you to the Commission for recognizing that this intersection needs improvement.

We have observed people speeding on this street for many years - driving at well over the posted limit of 40 mph! The problem has been exacerbated by the populaƟon growth in the past several years along with drivers wanƟng to avoid the traffic lights on Aviara Parkway. Puƫng an all-way stop at Aviara Drive and BaƟquitos Drive would be helpful but likely will not solve the problem. Some drivers will simply speed from Poinseƫa Drive or Aviara Parkway to that point! What could help is more police presence to enforce the speed limit on BaƟquitos Drive and more all-way stops (along BaƟquitos Drive) so that people know they cannot race through the area. Specifically, I suggest addiƟonal all-way stops along BaƟquitos Drive at Spoonbill and Kestrel. It is imperaƟve that something be done to prevent a serious accident from occurring.

We would like to attend the meeting regarding this proposal, but if we are unable to do so, we wanted our approval and support to be noted by email. We live in the Aviara neighborhood of Cantata II on Savannah Lane, and our home backs up to Batiquitos Drive. Because of our proximity to the roadway, we have directly observed traffic conditions at this intersection and along Batiquitos Drive. We strongly support the proposed stop due to the following concerns, especially since the speed limit on Batiquitos Drive was raised to 40 mph:  Increased vehicle speeds along Batiquitos Drive, often in excess of 40mph, which creates a more dangerous environment for drivers, pedestrians, cyclists, and nearby residents.  Drivers frequently disregard the three pedestrian crosswalks at Golden Star Drive, Aviara Drive, and Spoonbill Lane, proceeding through even when the warning lights are flashing and pedestrians are in the crosswalk. Many of us who are walking our dogs are forced to dodge oncoming traffic.  Around 7:30 each morning, students traveling eastbound towards Aviara Oaks Middle School on e-bikes often race down Batiquitos Drive, creating additional safety concerns when combined with fast-moving vehicle traffic.  Vehicles exiting the Aviara Golf Course Clubhouse and the Ember and Rye Restaurant sometimes pull onto Batiquitos Drive after drivers may have been drinking, which raises additional safety concerns.  An all-way stop would help slow westbound traffic; there is a blind curve when approaching Golden Star Lane which makes it difficult to see approaching vehicles traveling at high speeds.  Increased traffic noise and a general sense that traffic has become less safe for nearby residents. We believe an all-way stop would improve safety, calm traffic, reduce noise, and make the intersection safer for everyone who uses it. Thank you for your consideration and for your continued work to improve traffic safety in Carlsbad.

Community comments and questions. 1. Why did surrounding homes (within 1/2 mile) not get any notice? Found out through our Aviara Master Assn office thankfully. 2. What is the problem you are attempting to solve? What is wrong with the existing light with its left turn signal that I use constantly? Were you concerned about the long light for people leaving the Sanderling community? Are you trying to slow down all traffic....after school traffic will likely be quite a frustrating challenge when it becomes now super slowed down. Might stricter enforcement of existing laws work better. More red light cameras, finally encouraged by new California laws, SB 720 and AB 645 and more VISIBLE speeding enforcement, especially on Aviara Parkway and Batiquitos would be great! Late night speed races still happen on Batiquitos! 3. I thought we were all going to the much detested roundabouts? Thank heavens there probably is not enough room? Kids and dog walkers crossing would have no chance at all with a roundabout. 4. I walk my dog in the area at least twice a day. I have seen no one observing that area from the city. How were these three intersections selected? I never saw a traffic study at that intersection. 5. Being right near a rather large elementary/middle school you have tons of children on e-bikes. Do they get any training on this? I can only surmise children will be at risk with California rolling stops and people quickly accelerating. At least with a stop light, the kids have some indication when it is safe to cross. 6. Are there any warnings about upcoming 4 stop sign intersection? How many feet in advance? Will they be reflective/lit at night? Will you make sure that landscaping does not block the signs? I was the one who spent over 3 years with Carlsbad traffic personnel getting the 3 crosswalks on Batiquitos. As a dog walker, I can assure you that people rarely slow down unless you wave your arms at them, and, they even more rarely stop. They look right at you as they go by with the crossing indicator light flashing on. I am thinking of photographing license plates. Should I send those to the police? Would they send out a letter with the rules on crossing indicator lights to those motorists? ENFORCEMENT would be nice and there is a camera right on the lamp post directed toward the lagoon parking entry at the SW Corner of Spoonbill & Batiquitos! 7. Have you considered reducing the speed on Aviara Parkway and/or Batiquitos?.Then assign someone to enforce sporadically. These are my initial thoughts. I do hope that they are considered, and my questions perhaps even answered during the meeting on Monday at 4 pm. I do not know their answers, but I do know that I want safe intersections, for car drivers and passengers and people, especially children, and pets walking or otherwise crossing streets. 13 Thank you for your consideration and reading to the end.

I strongly support this proposal. As residents of Isla Mar, my spouse and I rouƟnely walk along BaƟquitos Drive and we experience many speeding vehicles passing that intersecƟon. Crossing the street there requires care, even with the help of the pedestrian crossing and flashing yellow lights that are available to warn drivers of pedestrians. There is a lot of speeding on BaƟquitos in both direcƟons, but especially by vehicles coming down the hill from the west. Also, Aviara maintenance workers driving uƟlity vehicles rouƟnely cross BaƟquitos Drive at that intersecƟon which puts them in danger of a collision. Lastly, as a related maƩer, the intersecƟon of BaƟquitos Drive and Kestral is another scary place to cross BaƟquitos due to speeding vehicles coming from the west and the limited sightline as the vehicles crest the hill and BaƟquitos curves towards the Kestral and Melodia Terrace cross streets. The city should consider the addiƟon of a crosswalk at Kestral with flashing yellow lights that would slow down the traffic and greatly improve the safety of pedestrians there.

While I appreciate the city's commitment to traffic safety, I believe that an all-way stop at this specific location is an inefficient solution that does not align with the actual traffic patterns of our neighborhood. I urge the Commission to consider the following points during the May 4 meeting: 1. Lack of Traffic Volume The cross-traffic at this intersection is consistently minimal. Batiquitos Drive serves a limited number of residential homes, while the opposing side consists of the driveway for the Hyatt golf clubhouse. Under the California Manual on Uniform Traffic Control Devices (MUTCD), stop signs should be installed based on specific volume thresholds. Installing an all-way stop where volume is naturally low leads to "stop sign fatigue," where drivers—realizing there is rarely a reason to stop—begin to roll through or ignore the sign entirely, creating a greater safety hazard than a free-flowing intersection. 2. Environmental and Efficiency Impacts Adding an unnecessary stop-and-start cycle at this intersection will lead to increased idling and vehicle emissions. Forcing every vehicle on Aviara Drive to come to a complete stop and then accelerate from zero creates a recurring "pulse" of acceleration that increases fuel consumption. This is contrary to the city’s broader sustainability goals and unnecessarily disrupts the efficient flow of traffic on a primary neighborhood thoroughfare. 3. Commercial vs. Community Interest The current configuration safely handles the volume of residents living on Batiquitos Drive and surrounding streets. The proposed change appears to prioritize the convenience of resort and golf club guests over the daily flow of the permanent residents who live along these streets. Public infrastructure decisions should prioritize the long-term efficiency of the community over the peak-hour convenience of a private commercial entity. 4. Alternative Solutions for Speeding If the city’s goal is to reduce speeding as stated in the notice, there are more effective traffic-calming measures available that do not penalize every driver and the local community. Options such as enhanced 17 striping, radar feedback signs, or "narrowing" the perceived lane width are proven to reduce speeds without the negative externalities of an all-way stop. I request that the Commission reject the recommendation for an all-way stop at Batiquitos Drive and Aviara Drive and instead direct staff to perform a more comprehensive volume study that accounts for the disparity between resident needs and resort traffic. Thank you for your time and for considering the perspective of the local residents who will be most impacted by this change.

Given that the intersection is in near proximity to an elementary school that has only increased in student population, the limited sight capabilities from Batiquitos on to Aviara because of elevation change, and the increased speed limits on Batiquitos from the original warrents.

CAUTION: Do not open attachments or click on links unless you recognize the sender and know the content is safe. Sent from my IPhone Traffic Safety & Mobility Commission Monday, May 4, 4 p.m. City Council Chamber 1200 Carlsbad Village Drive Good afternoon, City of Carlsbad and Traffic Safety and Mobility Commission, My name is Vitali Rodriguez, and I am a resident of Carlsbad. I’m here today to speak in support of installing all-way stop signs, with flashing lights and crosswalks, at the intersection of Camino De Los Coches and La Costa. This is not a new concern. According to the city’s own records, this intersection was evaluated as far back as 2018 and was found to meet the criteria for an all-way stop under the California Manual on Uniform Traffic Control Devices. At that time, staff recommended installation, but the Commission did not move forward with it. Now, nearly eight years later, this continues to be an ongoing safety issue for our community. On August 16, 2024, my son was nearly struck by a speeding vehicle at this intersection—an experience that was deeply frightening for our family, especially as it happened just one day before his 8th birthday. It is a moment I will never forget. While I am incredibly grateful that he was not hurt, the incident highlighted how vulnerable pedestrians are at this crossing. Since then, I have continued to notice how frequently this intersection is used by children and families. Students and friends from Mission Estancia Elementary, Diegueño Middle School, and La Costa Canyon High School regularly walk or bike through this area. Neighbors also cross here to access Los Coches Village Shopping Center, and many parents with young children and their pets use this route to reach Stagecoach Park. These are not isolated incidents—they reflect a real and ongoing risk. On October 31, 2025, Halloween night, we also had a high school-aged neighbor and friend who was struck by a vehicle at this same exact location and spent two days in the hospital recovering from his injuries. His mother told me, and I quote: “I get emotional because I know what it felt like to rush to a trauma center. It’s a miracle my son is alive.” This incident occurred at night, when visibility is even more limited. This is why I strongly encourage not only the installation of all-way stop signs and crosswalks but also flashing lights to improve visibility—especially during nighttime hours. Simple measures like this can make a meaningful difference in helping drivers recognize the intersection sooner and slow down. While I understand that different traffic control options have been considered, including signals and roundabouts, the fact remains that this intersection has already met the criteria for all-way stop signs since 2018. In the interest of safety, I respectfully urge the Commission to take action now, before another serious or preventable tragedy occurs. Our community has been waiting for years. We simply want a safer environment for our children, our families, and everyone who uses this intersection. Thank you for your time, your consideration, and your commitment to community safety.

I am adamantly opposed to this. It would be far more dangerous to pedestrians crossing 4 lanes of highway, hoping all cars stop for them. Pedestrians will get hit. Traffic lights force all cars to stop simultaneously in a given direction, cueing pedestrians that it is safe to cross and allowing pedestrians ample time to cross. The car flow is far more random with stop signs. Additionally, this would create chaos and gridlock, especially when parents are taking children to and from the schools. And the kids on e-bikes? They do stop at red lights, but they do NOT stop at stop signs. Such a dangerous idea. If you really want to slow traffic, install speed bumps. They are cheap and they work. Please don't waste any more of my money on something so absurd.

This request follows a series of serious accidents at this location, including an incident on Halloween evening of 2025 where my son was struck by a speeding vehicle while riding his e-bike. Despite following all safety regulations, he was hit by a driver who was significantly exceeding the speed limit. Most recently, another child—the son of a family friend—was struck in a second incident occurring less than six months later. This intersection serves a high-traffic residential area where families with small children and senior citizens frequently walk. My neighbors and I have reached out on several previous occasions to express our concerns regarding the lack of traffic control and the persistent issue of speeding, yet no corrective action has been taken to date. The safety of our community is at stake, and we can no longer afford to wait for another accident to occur.

As a resident of tamarack I witness rapid speeds on a daily basis. My concern is for the large amount of children who use tamarack as a route to school. I support any means necessary for making our streets safer for the residents of Carlsbad, and slowing down traffic. We have already had two pedestrian fatalities from reckless driving within a mile of this intersection. Please let’s make that the last.

I am very relieved to know that the city is proposing to help with traffic safety in this area by potenƟally puƫng stop signs. Thank you . While this is an improvement, I strongly suggest that a traffic light be put instead along with a pedestrian crossing. La costa Canyon high school is very near to this intersecƟon and there a so many students walking to and from school, walking to and from La costa town square during lunch breaks along with residents doing their daily walks. It is quite a safety issue crossing the street with all the cars turning leŌ or right from either direcƟon . Likewise, the speed through which cars go along La costa avenue is concerning. I have personally witnessed and experienced near collisions because those turning leŌ from Caminos de los coches cannot necessarily see the cars speeding through La costa avenue. I also have seen and heard people doing “donuts” in this intersecƟon almost each night which is such a nuisance to the community. With the new apartments being built nearby, the amount of traffic will significantly increase. For the reasons above, I am fervently hoping the city of Carlsbad put a traffic light in this intersecƟon . Thank you for your aƩenƟon.

This proposed traffic change will undoubtedly improve safety of ingress and egress to my neighborhood and I strongly support it. With no stops on Batiquitos between Aviara Pwy and Poinsettia Ln, there is little motivation for drivers to slow to posted limits. Even with the flashing lights at crossings, I still experience drivers speeding past me while I walk my dog in the crosswalk. This is a much needed safety measure for the neighborhood. I look forward to its implementation.

Twice daily walks (7-9am & 5-7pm) along Batiquitos from the trailhead @ Golden Star and the intersection at Aviara Parkway provide several insights during high traffic periods:  eastbound traffic near the Golden Star trailhead due to the steep hill decline is mostly above posted speed limit  westbound traffic is also mostly above the speed limit due to the steep hill decline from Aviara Parkway intersection  posted speed limit signs along the "flat" stretch of Batiquitos are there but not particularly prominent  short of installing a full four way stop there might be room to discourage excess speed by posting more aggressive and prominent signs  otherwise, I would not object to taking whatever measures are judged necessary to reduce autospeed along the flat stretch of Batiquitos  one additional development worth monitoring is the increased use of "E" bikes that often travel three or more abreast in the bike lanes which are at great risk of collision with cars traveling at excessive speeds.

I support the proposed all-way stop at Batiquitos Dr. and Aviara Dr. I am a frequent pedestrian at that intersection. It is not safe. The vehicles on Batiquitos Dr. frequently exceed the speed limit - often at speeds of 50 mph or faster. Many do not stop at the flashing pedestrian signal. It is risky to allow the intersection to remain without a four-way stop. The intersection is risky for pedestrians and the cross- traffic. Thank you for your consideration of this proposed all-way stop.

The eastbound downslope on Aviara means that most cars exceed the posted speed of 40 mph. By the Ɵme they approach Bataquitos intersecƟon, if it’s a green light, they head towards the Ambrosia intersecƟon going at speeds that can cause a fatality. The crossing guards have told of having to pull kids out of the crosswalk to prevent them being hit, as cars race through it. Teachers are aware that it is hazardous for the kids on e-bikes, having seen them have to avoid being hit. A teacher passed along to me this weekend, she was aware of two student e-bike collisions that caused serious injuries. Forcing drivers to stop then proceed at a slower speed, will protect children from a high speed collision. And, I,d expect, protect the city from a costly law suit.The hazardous condiƟons are known by the surrounding neighborhoods, the crossing guards and the teachers. Dealing with risk miƟgaƟon preempƟvely with the 4 way stop is a welcome soluƟon. Donna Hunt 1629 Baccharis Sent from my iPad, 苓苔苖苕 Donna Hunt.

This will allow many children living in the surrounding neighborhoods to have safer access to schools and the park. I do think there is a beƩer way to ease the traffic at that intersecƟon with use of a roundabout instead of adding an all way stop. The flow of traffic at this intersecƟon is heavily impacted by traffic to and from La Costa Canyon High School. In the aŌernoon there are many cars turning leŌ from Camino de Los Coches to La Costa Ave, most of which look like high school students. OŌen I see students turn right, to avoid the backed up leŌ turn, then quickly make an illegal u-turn at Calle Pera or SiƟo Lima. This poses an addiƟonal risk for pedestrians and other vehicles. I do worry that an all way stop sign will not help alleviate this traffic congesƟon Jessica Brady Carlsbad Resident 7388 SiƟo Lima CAUTION: Do not open aƩachments or click on links unless you recognize the sender and know the content is safe. 6 Lovelynne Magalued From:Kazim Konyar <KKonyar@csusb.edu> Sent:Monday, May 4, 2026 11:11 AM To:Traffic Subject:Proposed stop sign at the corner of Tamarack and Sunnyhill We live at the corner of Tamarack Ave. and Sunnyhill Dr. We oppose the placement of all-way stops at this corner for the following reasons: 1. There are speed pumps at this intersection that already slows the traffic. 2. There is already a flashing light pedestrian crossing ensuring safe crossing without a need for stop signs. 3. Cars stopping and taking off would result in more exhaust pollution and car noise. Thank you for taking my family's concerns into account.

If the intent is to slow traffic, how about reducing the speed limit and enforcing it! I don’t see how an all way stop is easier than a traffic light for speeding cars to see as they zip down the hill. In addiƟon, many children (and dog walkers) use the pedestrian walk signal that would be eliminated by an all way stop. Very dangerous!

The conversaƟons I’ve had with the traffic engineer and police representaƟves were all directed at Aviara Parkway and Bataquitos, NOT Aviara Drive There are downhill slopes on Aviara Parkway that cause drivers to exceed the posted speed limit of 40 miles an hour 25 mph is rarely observed. If there is a green light at Bataquitos and Aviara Parkway cars going east aŌer the downhill slope, are driving at speeds that will cause a fatality. The children that walk or ride bikes to school have had to be rescued from near misses as drivers try to screech to a stop at the last minute or try to drive through a light that just changed to red. I,ve nearly been hit walking across Aviara Parkway at that intersecƟon, as a woman exceeding the speed limit finally was able to stop halfway into the crosswalk I was in. I had welcomed the idea of a four way stop at Bataquitos and Aviara Parkway since it would force drivers to stop and then proceed slowly to the intersecƟon at Ambrosia and Aviara Parkway by the school. The traffic from outlying areas driving through the neighborhood is increasing while the student populaƟon at the school is growing. I,d like to refocus the CommiƩee on a soluƟon to this higher risk intersecƟon than Bataquitos and Aviara Drive. Funds are limited and protecƟng school children that ride bikes and walk to Aviara Oaks School is a necessity. I,m not sure what steps to take to resolve this. How does the CommiƩee and the City of Carlsbad refocus on a soluƟon to risk miƟgaƟon by Aviara Oaks School? Parents, teachers and the crossing guards are concerned it may not happen before a child is hit, perhaps fatally. How does this become a priority? Donna Hunt, 707 338-3931 .
