Approval of the Traffic Calming Plan for Implementation on Unicornio Street
3 Recommended Actions
Adopt a resolution approving the traf fic c alming plan for implementation on Unicornio Street.
Executive Summary
The city has been addressing residents’ speeding concerns on Unicornio Street between El Fuerte Street and Rancho Cortes using the 2011 edition of the Carlsbad Residential Traffic Manageme
nt Program. This street qualified for traffic calming consideration through Phase 2 o
f the program with a measured critical speed – the s peed at which 85% of the vehicles were traveling at or below – of 32 mph.
This traffic calming pla n , consisting of two speed cushions for Unicornio Street, received s
upport from the residents and non-resident property owners as measured by a mail support survey as outlined in the program.
Staff presented the proposed traffic calming plan and associated mail survey results for Unicornio Street to the Traffic Safety & Mobility Commission and the commission voted in support of the project.
The City Council’s approval is required to implement the traffic calming plan under the program’s project approval process.
Explanation & Analysis
Overview
Residents in the area contacted the city with concerns about speeding on Unicornio Street. In response, staff initiated the Residential Traffic Management Program’s Phase 1 process and deployed temporary speed feedback signs on the street. These signs were deployed for a two- week period and served two purposes:
• To colle
ct speed data with the display off
• To educate drivers of their traveling speeds with the display on June 23, 2026

At the same time as the traffic calming process was underway on Unicornio Street, staff were also working on an update to the Residential Traffic Management Program, which was approved as the Carlsbad Traffic Management Program by the City Council on April 14, 2026. As noted in the City Council memorandum dated Aug. 28, 2025, (Exhibit 2), staff continued processing the proposed traffic calming on Unicornio Street using the previous 2011 version of the traffic management program. (Exhibit 3)
The critical speed on Unicornio Street was measured to be 32 mph and therefore met the 32 mph threshold to be eligible for Phase 2 of the 2011 program, so staff initiated the Phase 2 process for Unicornio Street for traffic calming consideration.
A traffic calming concept plan consisting of two speed cushions on Unicornio Street between El Fuerte Street and Rancho Cortes was then developed in coordination with the Transportation, Fire and Police departments.
Neighborhood meeting
Staff invited residents and non-resident owners within the project area to a neighborhood meeting on April 17, 2025, to discuss traffic calming strategies and gather feedback on a traffic calming concept plan featuring two speed cushions on Unicornio Street. Staff members from the Transportation, Fire and Police departments participated in this neighborhood meeting.
Mail survey
Under the 2011 program, a proposed traffic calming plan requires the support from the residents and non-resident owners in the project area as measured by a mailed support survey.
The survey is considered valid if 50% or more of the residents and non-resident owners return the completed survey. Positive support is indicated by 67% or more of the surveys returned in support of the traffic calming plan. Survey results for Unicornio Street are summarized in the table below.

The 2011 Residential Traffic Management Program states that, “a duly noticed public meeting will be held by the City Council to receive the recommendations of the Traffic Safety Commission for Phase II implementation.”1
Fiscal Analysis
Sufficient funding is available in the Traffic Improvement Program, Capital Improvement Program Project No. 6070, to complete the project. The available funds and estimated construction costs are shown in the following table:
Traffic Improvement Program
Capital Improvement Program Project No. 6070
Total appropriation to date $4,188,000
Total expenditures and encumbrances to date -$3,190,568 Total available balance $997,432
Traffic calming for Unicornio Street
Construction contract (estimated) -$20,000
Construction contingency (estimated) -$5,000
Construction management, inspection and material testing (estimated) -$5,000 Total estimated construction costs -$30,000
Remaining balance $967,432
Additional appropriation needed $0
Next Steps
With City Council’s approval, staff will move forward with implementation of the traffic calming plan on Unicornio Street. Because the estimated construction cost falls within the threshold for the minor public works contract process, staff will solicit bids from contractors for construction of the project. Carlsbad Municipal Code Section 3.28.040 authorizes the City Manager to award the construction contract in an amount less than $220,000 to the selected contractor.
Environmental Evaluation
The proposed action to approve the traffic calming plan on Unicornio Street for implementation is categorically exempt from the environmental review under California Environmental Quality Act, or CEQA, Guidelines Section 15301 because it involves the maintenance, repair, or minor alteration of existing facilities with negligible or no expansion of the existing or former use. No exceptions to the categorical exemption as set forth in CEQA Guidelines Section 15300.2 or Carlsbad Municipal Code Section 19.04.070(C) apply.

EXECUTIVE SUMMARY
In all areas of Carlsbad, daily commuter traffic or other types of traffic drive on neighborhood streets.
Speeding and/or excessive volumes may cause residents to become alarmed about safety and quality of life. When the tranquility and ambiance of the neighborhood is disrupted by drivers speeding or trying to find short-cuts, concerned citizens contact City officials.
This scenario, repeated each day in some areas of the City, alerted the City Council to the need for a comprehensive citywide program to minimize excessive speeds and high volumes in neighborhoods.
Similar problems in California and throughout the country have inspired engineering solutions called traffic calming, which is a method of slowing cars and discouraging cut-through traffic. With traffic calming in mind, the City Council elected to use a citizen-based approach to develop such a program, appointing a committee of seven citizens to work with staff in developing solutions for any Carlsbad neighborhoods seriously affected by traffic problems.
The citizen's committee developed a three-phase approach to addressing traffic problems in Carlsbad neighborhoods. After reviewing and evaluating programs from many cities, the committee recommended a program it suitable for Carlsbad and which would achieve the three goals that must be met if traffic calming is to be successful. The first requirement is support of the residents in any neighborhood where such calming is needed. Second, the traffic calming measures must meet with the approval of emergency agencies concerned about response times, as well as the needs of other utilities whose large vehicles could be adversely affected or damaged by the traffic calming measures. Finally, the residents must be willing to live with the actual traffic calming measures designed to slow traffic and cut-through traffic volumes in their neighborhood.
This document represents the first revision to the initial program developed by the Carlsbad Residential Traffic Management Program Committee. The primary reasons for revising the program were to add lower cost traffic management tools such as residential stop signs and speed cushions and to establish benchmark criteria for the funding of future traffic calming projects. The revised program is divided into the following three phases:
Phase I: application of enforcement and education to resolve non-compliance issues.
Phase II: utilizing engineering-based measures to increase compliance with posted speed limits and discourage cut through traffic.
Phase III: development and implementation of a comprehensive plan comprised of traditional traffic calming measures to address traffic issues while enhancing the residential character of the street.
Ultimately leading to improvement in the quality of life of affected neighborhoods, the Carlsbad Residential Traffic Management Program is still another way in which the City provides for the health, safety and welfare of its citizens.

CARLSBAD RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
1 CARLSBAD
RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
INTRODUCTION
Virtually every day, on many residential streets, Carlsbad residents are faced with the potentially dangerous intrusion of speeding vehicles and/or cut-through traffic. Carlsbad streets have experienced escalating traffic impacts due to population and employment growth. As a result, an increasing number of citizens have expressed concerns to City officials, the Police Department and Engineering staff about these traffic problems.
Carlsbad residents are not unique in voicing such concerns. Cities throughout the United States have struggled with the issue of escalating traffic speeds and volumes on residential streets. As a result, citizens have asked that their neighborhood quality of life be improved through a reduction of vehicle speeds and volume. Many desire the simple pleasure of being able to walk or ride bicycles through their neighborhoods without fear of vehicular traffic, a key factor in neighborhood livability.
"Livable" cannot be precisely defined as it relates to community or neighborhood. However, the residents' expectation that fewer vehicles should be speeding down neighborhood streets is an indication of their desire to reside in a livable neighborhood. Characteristics of such a desirable neighborhood include:
a sense of community
a safe place to walk or bicycle
interaction among neighbors
a general feeling of security and safety
the opportunity for residents to enjoy their homes and property streets that do not penalize drivers traveling at the posted speed limit
"Traffic calming" is a term that has, in recent years, become synonymous with providing the means to slow vehicles, reduce cut-through traffic volumes and help achieve a livable community. Through the use of a variety of measures, physical or otherwise, traffic calming helps reduce the undesirable effects of the motor vehicle in residential neighborhoods.
In response to the concerns of Carlsbad residents, the City Council has established the Carlsbad Residential Traffic Management Program, referred to as the CRTMP, to address neighborhood concerns about unwanted traffic. The Institute of Transportation Engineers (ITE), an international organization of transportation professionals, has defined traffic calming as:
"The combination of mainly physical measures that reduces the negative effects of motor vehicle use, alters driver behavior and improves conditions for non-motorized street users."
Carlsbad's Residential Traffic Management Program is designed to have significant neighborhood involvement. Staff plans to work closely with residents to identify problems and their solutions and to gather the support necessary to ensure the success of any traffic calming plan that may merit adoption.
Communication with the residents at each step is critical and the urgency of plan development will not June 23, 2026

2 be allowed to override the need for thorough understanding, commitment and approval by the neighborhood.
Since neighborhood involvement is the key, the program is designed to solicit and encourage residents' active participation in identifying concerns, developing reasonable solutions and supporting the final outcome. In the traffic engineering field, the manner in which this occurs is a process that contains the elements of the “4E's":
Education
Engineering
Enforcement
Enhancement
By utilizing the "4E" process, which incorporates a comprehensive, integrated involvement of concerned residents, the challenge of identifying and resolving problems can successfully take place.
The basic elements of the 4E process include:
Education: Providing resource materials and information to residents to inform them about all aspects of traffic calming.
Engineering: Physical measures and other techniques utilized in the traffic calming program that are based upon input and concurrence by residents, engineering principles, financial and environmental considerations.
Enforcement: Police presence and selective enforcement of vehicle code violations.
Enhancement: Using special treatments in the physical measures through design and/or landscaping features to improve livability, aesthetics, community pride.
This program has been established with and conforms to authority and responsibility given to local authorities by the California Vehicle Code to protect the health and welfare of its citizens. Additionally, it meets one of the goals in the Circulation Element of the General Plan that states Carlsbad is a "City with an integrated transportation network, serving local and regional needs, which accommodates a balance of different travel modes based upon safety, convenience, attractiveness, costs, environmental and social impacts".
It is the policy of the State of California that all persons have an equal right to use public streets and that no agency may restrict the use of streets to only certain individuals. With certain exceptions provided for in the California Vehicle Code, the specific authority to regulate travel upon streets can only occur in specific instances related to:
implementation of the Circulation Element of the General Plan criminal activity
regulating or prohibiting processions or assemblages
streets dividing school grounds to protect students attending such schools or school grounds

CARLSBAD RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
3 Requests to implement the CRTMP will ultimately be considered through the process outlined in this program. Careful consideration will be given to each request to ensure that it meets State law and the criteria contained in the program.
GOALS
The City Council established the CRT MP as a countermeasure to intrusion by excessive traffic and/or higher than normal vehicle speeds in the neighborhood and thus, to help improve the quality of life.
With a defined traffic management process and established procedures contained in this document, Carlsbad residents will have the measures and techniques ("tools") at their disposal to avert many negative impacts associated with vehicular traffic on residential streets.
The goals of a traffic management program include:
improving the quality of life in the neighborhood
creating safe streets by reducing the collision frequency and severity reducing negative effects of motorized vehicles
design of features that encourage self-enforcement
PROGRAM STRATEGIES
The City of Carlsbad strives to achieve neighborhood livability through implementation of current standards and policies. Managing traffic is a key component in this endeavor and one that is vital for promoting characteristics of livable neighborhoods. Therefore, strategies are needed to identify and address issues revolving around speeding, excessive volumes and safety concerns on residential streets when it occurs. These strategies include:
developing recommendations that adhere to State law
satisfactorily addressing legal and liability issues
preserving reasonable emergency vehicle access and response time consistent with response standards
maintaining reasonable vehicular access
promoting neighborhood safety for pedestrians, bicyclists, motorists and residents encouraging and incorporating citizen participation in identifying traffic calming measures and techniques
utilizing City resources and funds efficiently and effectively utilizing a combination of education, engineering, enforcement and enhancement (4E's) maintaining, encouraging and enhancing pedestrian, bicycle, transit and alternative modes of travel
balancing on-street needs (such as parking) with the reasonable and safe function of the street considering achievable options for funding
According to the ITE resource, “Transportation and Land Developm ent, 2 nd Edition”, residential streets should ideally be designed and constructed to a “residential neighborhood scale” to achieve vehicle speeds and traffic volumes consistent with typical neighborhood uses. Residential neighborhood scale is June 23, 2026

CARLSBAD RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
4 typically accomplished by restricting roadway length so that a driver slows, stops, or makes a significant turning movement every 300-700 feet. Drivers tend to comply with speed limits in residential neighborhoods when the effective, uninterrupted street length is less than 700 feet.
Complaints related to excessive vehicle speeds often originate on residential streets that have not been designed to this residential neighborhood scale. The CRTMP attempts to resolve these types of speeding issues by installing a series of traffic management measures to reduce the effective street length so that a driver slows, stops, or makes a significant turning movement every 300 to 700 feet.
Traffic management measures are recommended to be spaced, on average, at approximately 500 foot intervals. The traffic management strategies included in the CRTMP toolbox are designed to work in concert with one another to limit the effective, uninterrupted length of an existing street to approximately 500 feet, which should result in a reduction in vehicle speeds and render the route less attractive to cut-through traffic.
PROCEDURES
The procedures to implement traffic management measures and techniques are described on the following pages and are referred to as phases. In general, the established procedures are consistent with the methodology currently used in Carlsbad to address any traffic-related concerns. The procedures require, and are designed to encourage, substantial neighborhood participation, following the process used by staff to formulate solutions to problem locations and the methods for proposing those solutions to the Traffic Safety Commission and City Council for final resolution.
Carlsbad's Residential Traffic Management Program has been developed as a three- ph ase program,
consisting of the following structure approach:
Phase I : Enforcement and Education
Phase II : Traffic Management
Phase III : Traffic Calming
The program is designed in such a way that residents of each street with identified problems, and with neighborhood support and commitment, can play a part in the program. The cost, complexity, effectiveness and impact to residents increase with each phase. Phase I features are generally considered simple improvements that can be initiated internally and provided by city staff. Phase II consists of cost-effective traffic management features that may reduce vehicle speeds but may also penalize those who drive at the legal speed limit. Phase III features are the most effective at traffic calming but are expensive and may negatively impact parking.

CARLSBAD RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
5 PROGRAM ELIGIBILITY
Participation in the Carlsbad Residential Traffic Management Program requires the following:
1. The subject street must meet the legal definition of residence district (as defined by the California Vehicle Code) or designated school zone (as defined by the California Manual on Uniform Traffic Control Devices).
2. The subject street must have a curb-to-curb width of 40 feet or less.
3. A letter sent by a resident or residents requesting that staff consider a subject street for inclusion into the CRTMP process.
Any street that does not meet the program eligibility criteria but is nevertheless considered by city staff to be a candidate for traffic calming will be scheduled for review and possible approval by the Traffic Safety Commission. If the Commission's review leads to the conclusion that the street merits an exception, it will be processed through the CRTMP as if program eligibility criteria were met. Any street recommended by the Traffic Safety Commission as not qualifying for an exception may be requested by a citizen to be reviewed by the City Council for a final determination. The exception process may be used for consideration for inclusion into each phase of the program.

CARLSBAD RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
6 PHASE I: EDUCATION AND ENFORCEMENT
When a resident, or group of residents, from a neighborhood has a traffic-related concern that they believe should be addressed by the Carlsbad Residential Traffic Management Program and have sent a letter to the Traffic Division of the Transportation Department, the process will be initiated in the following manner.
Step 1 Initiate Traffic Request (TR) Procedure
Upon receipt of the correspondence and verification that the subject street satisfies program eligibility requirements, staff will initiate a Traffic Request (TR) that includes the information contained in the letter. The TR is an internal logging and tracking system in the Transportation Division used to initiate action and file correspondence. An engineer will be assigned to investigate and conduct an engineering study of the street(s).
Step 2 Investigation/Studies
Staff will gather preliminary data about the expressed concern. Field reviews and appropriate traffic studies will be conducted. They may include:
geometric conditions of the road volume counts
parking availability/restrictions pedestrian counts location of existing traffic control devices collision analysis speed surveys other studies as determined appropriate
Phase I strategy will be formulated after the data is collected.
Step 3 Coordination with the Police and Fire Departments
Staff will discuss with the Police Department solutions that can be addressed through enforcement. An enforcement strategy will be prepared and implemented by the officer in charge of the Traffic Division of the Police Department. Concurrently, staff will discuss with the Fire Marshal emergency response route issues and other fire safety issues.
Step 4 Issue Work Order
Implementation of Phase I can be accomplished by city forces. Staff can usually issue work orders for the installation of signs or striping or implementation of speed feedback signs.
Step 5 Communication with Residents
Information on appropriate traffic calming strategies and techniques proposed to address the identified concern is shared with the person or group that initiated the request, including information about the issuance of work orders. Staff also outlines the engineering and enforcement approach that will be utilized to mitigate neighborhood concerns.

8 PHASE II: TRAFFIC MANAGEMENT
If all applicable Phase I options have been completed and do not appear to adequately address the problem after being in place for an appropriate amount of time as determined by the city staff, Phase II of the CRTMP may be considered.
Step 1 Written Request
Phase II will be initiated when an affected resident that resides on the street where the concern exists sends a letter to the Traffic Division of the Transportation Department requesting Phase II consideration.
The letter will be generated by a resident, following discussions with city staff to review what might be accomplished through Phase II of the program.
Step 2 Phase II Eligibility Determination
Not all residential streets and/or residential areas will qualify to participate in Phase II of the Carlsbad Residential Traffic Management Program based upon the established process. Eligibility criteria for Phase II are as follows:
1. Completion of Phase I of the CRTMP; and
2. The 85th percentile speed (critical speed) must be 32 miles per hour or greater as determined by a speed survey(s).
Both of the eligibility criteria must be met for a street to be considered for further processing through the CRTMP. However, on a case- by-case basis, city staff may determine exceptions. A street considered as an exception must be approved by the Traffic Safety Commission.
Step 3 Determine Project Area of Influence (PAOI)
The street or streets significantly impacted by neighborhood concerns or potential solutions, including all dwelling units or other land uses bordering the subject street or streets, comprise the Project Area of Influence (PAOI). The PAOI will be established by city staff, with input from the neighborhood representatives. The establishment of the PAOI by staff shall consider the implementation of measures on a roadway system as opposed to singular, isolated installations.
Step 4 Phase II Concept Plan
All residents from the PAOI will be invited to a neighborhood meeting hosted by the city. At the meeting, staff will explain the Phase II process that may lead to installation of the traffic management measures proposed for their neighborhoods. Discussion will include:
neighborhood concerns
traffic data gathered
results from Phase I
potential Phase II solutions
advantages/disadvantages of specific Phase II features
Phase II approval process
A Fire Department representative will be invited to attend the meeting to explain response needs of the emergency service providers and any concerns with potential traffic management on the candidate June 23, 2026

9 street. Also, a Police Department representative will be invited to attend the meeting to respond to questions about enforcement issues.
Staff, using the data collected in Phase I, and working with affected residents, will draft a plan of proposed Phase II measures within the boundaries of the PAOI. Since Phase II measures are limited in application, they may not be appropriate for a given situation. For example, if a subject street does not feature intersections, residential STOP signs would not be appropriate. Staff will work with residents to prepare the Phase II concept plan which will be presented to the neighborhood via mail survey for support.
The concept plan will be presented to the Traffic Safety Coordinating Committee to allow city staff such as Fire Department and Police Department representatives to review and comment.
Step 5 Mail Support Survey for Phase II Concept Plan
A mail support survey will be conducted by City staff upon completion of the Phase II concept plan developed by staff. The purpose of the survey will be to determine if the neighborhood (as defined by the PAOI) is in favor of the proposed plan.
Residents and non-resident owners within the PAOI are eligible to participate in the mail support survey.
Distribution of the support survey will be conducted by the City through the mail. The survey will be considered valid if a minimum of 50% of the residents contacted fill out and return the completed survey. Staff will then analyze the returns to determine if 67% or more of the PAOI community responding supports the Phase II plan.
If the Phase II concept plan includes measures with vertical deflection such as speed cushions or speed tables, support for these measures from residents directly affected will be highly desirable. Staff will work with these residents and will strive to balance the concerns of individual residents with the overall success of the concept plan as a system of interdependent features. Since the success of Phase II will be dependent on the spacing of proposed features, the removal of any measure from the concept plan due to lack of support may have a detrimental effect on the concept as a whole.
If 50% of the surveys are not returned, an outreach program may be initiated by the resident(s). Re- survey will occur after all steps established in the outreach program are completed. A re-survey will be valid if 50% or more of the surveys are returned to staff. If the plan is not approved by 67% or more of the returned surveys, the resident(s) may request that staff develop an alternative plan or abandon their efforts. A revised Phase II plan will be tested by the support survey process in this step. If the revised plan fails to garner support of the residents in the PAOI after the second survey, no further surveys will be conducted by City staff for a minimum of one year.
Step 6 Final Approval by the City Council
The approved Phase II concept plan will be brought forward to the Traffic Safety Commission for recommendation and to hear public testimony on the matter. A duly noticed public meeting will be held by the City Council to receive the recommendations of the Traffic Safety Commission for Phase II implementation. If Council decides that Phase II is acceptable as presented, it will so indicate by adopting an ordinance authorizing installation of residential STOP signs and/or other proposed measures and authorizing the appropriation of any necessary funds . The Council may consider other June 23, 2026

10 options such as returning to the neighborhood for refinement of the Phase II concept plan or proceeding to Phase III of the CRTMP.
Step 7 Phase II Implementation
Implementation of Phase II, in most cases, will be performed by city forces via work orders issued by staff.
Step 8 Phase II Monitoring
Phase II measures that have been installed will be monitored for effectiveness during the first year following completion of the installation. Staff will analyze traffic data results, accident history, observed deficiencies and/or impacts of the Phase II measures, comments, and suggestions or complaints received.
If some residents of the neighborhood believe that the impacts and results of Phase II do not meet their expectations, they may request removal of the permanent measures. The request for removal must follow the Traffic Calming Measures Removal Process and be submitted at least one year from date of Phase II installation.

11 PHASE III: TRAFFIC CALMING
If applicable Phase II options have been evaluated and do not appear to adequately address the problem as described previously, Phase III of the CRTMP may be considered. Phase I II of the CRTMP is designed to allow traditional traffic calming measures to be used in areas where Phase II options have not adequately resolved the traffic issues. Due to the potential fiscal impacts of Phase III and probable
impacts to parking capacity and limit access to properties, residents will be required to first utilize Phase II measures before requesting to proceed to Phase I II. Phase I II measures will be limited to locations where re-routed traffic will only impact higher classified roadways. Residents have the option to bypass Phase II only if funding is privately secured and all Phase III criteria are satisfied.
Step 1 Written Request
Phase I II will be initiated when the affected residents send a letter to the Traffic Division of the Transportation Department requesting Phase III consideration. The letter will be generated by the residents following discussions with city staff, study of Police Department results of Phase II, and anticipation of what might be accomplished through further utilization of the CRTMP process. The Phase III process will require an evaluation of a qualification criteria as well a neighborhood-initiated support petition.
Step 2 Project Scoring and Qualification Criteria
Candidate streets will be evaluated on the following factors and associated points for the purpose of establishing a project score for funding considerations . Streets with a score exceeding 50 points will be eligible for Phase III.
Criteria and points assigned are as follows:
1. Travel Speed (maximum 40 points):
6 points for each mile per hour the 85 th percentile speed is over 32 miles per hour.
2. Traffic Volumes (maximum 30 points):
Typical weekday ADT divided by 100 and rounded to the nearest whole number or the weekday peak hour volume divided by 10 and rounded to the nearest whole number.
3. Collision History (maximum 15 points):
Five points will be assigned for each correctable collision on a street, including intersections, within the past five years. A correctable collision is one that might have been prevented by the installation of a traffic control device or traffic calming measure.
4. Sidewalks (maximum 5 points):
5 points if no sidewalk or pedestrian pathway exists on either side of the street. 5 points if no sidewalk or pedestrian pathway exists along at least one side of the street.
5. School Proximity (5 points maximum):
5 points if school grounds abut the candidate street.
3 points if the PAOI is within 500 feet of school grounds. 1 point if the PAOI is located within 1,000 feet of school grounds.

14 Step 3 Neighborhood Support Petition
If the subject street meets the Phase III Qualification Criteria, concerned residents will need to establish resident support for continuation of the Phase I II process. The support petition is initiated by the neighborhood representative and serves as the mechanism to establish that residents’ support the City's consideration of a Phase I II traffic calming project. Documentation of support for consideration of a future project is indicated by a simple majority (50% plus one signature) of those eligible individuals located within the PAOI that sign the petition. The petition form will be developed by staff but it will be the responsibility of residents to circulate the petition and submit the results.
Step 4 Project Funding
Upon satisfaction of Steps 2 and 3 of the Phase I II process, the subject street may be considered for funding as a future project through the Capital Improvement Program (CIP) process. If more than one CRTMP project is submitted in a given fiscal cycle, priority will be established by the Phase II I Qualification Criteria scoring. Many different fiscal factors must be considered to establish if and to what level funds will be allocated for projects on the priority list. Staff will recommend a funding level and the City Council will consider and adopt the annual budget before the fiscal year ending on June 30.
As an alternative to the City funding the design and construction of Phase III improvements, residents may choose to collect funds themselves in any manner they choose, including the formation of an assessment district. This private funding must be for 100% of the project cost including design, construction, inspection, administration and contingency costs associated with the project. Private funds must be deposited with the city prior to proceeding to Step 4.
Phase III will not proceed until funding source is identified and funds are secured.
Step 5 Kick-off Meeting with the Neighborhood
All individuals from the PAOI will be invited to a neighborhood kick-off meeting hosted by the City. At the
meeting, staff will explain to those in attendance the Phase I II process that may lead to installation of the traffic calming measures proposed for their neighborhoods. Discussion will include:
neighborhood concerns
traffic data gathered
results from Phase I and II
potential solutions
traffic calming plan development process
before and after traffic study process
A Fire Department representative will attend the meeting to explain response needs of the emergency service providers and any concerns the Fire Department has with potential traffic calming on the candidate street. Also, a Police Department representative will attend the meeting to respond to questions about enforcement issues.
Step 6 Develop the Conceptual Neighborhood Traffic Calming Plan By meeting and working closely with the residents, staff will be able to assist in:

CARLSBAD RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
15 assessing neighborhood needs
identifying alternatives
developing initial plans or solutions
finalizing the comprehensive plan based upon
o sound engineering principles
o neighborhood input
o state-of-the-art traffic calming practices
Throughout design development of the conceptual plan, all residents within the PAOI will be provided updates and will be encouraged to offer input. The residents will be actively involved in all aspects of developing the comprehensive neighborhood traffic calming plan and will be expected to commit the time and effort needed to develop a successful plan. Directly affected residents and property owners will be notified and involved with the development of the conceptual plan.
The length of time needed to develop the conceptual plan is dependent upon the complexity of the issues, the level of neighborhood involvement and support, project cost and the willingness of the residents to aggressively pursue plan development. The series of meetings leading to completion of a final conceptual plan for presentation to the neighborhood could take six months or longer.
Step 7 Mail Support Survey for Final Conceptual Plan
A mail support survey will be conducted by city staff upon completion of the conceptual plan developed by residents and staff and evidence of a generally favorable consensus on the plan by interested residents. The purpose of the survey will be to determine if the neighborhood (PAOI) is in favor of the proposed plan by a super majority (67% or more).
Residents and non-resident owners within the PAOI will be included in the survey, essentially following the eligibility procedures addressed in Phase II. If necessary, and as determined by city staff based upon the proposed conceptual traffic calming plan, additional properties may be included or excluded by expanding or reducing the boundaries of the PAOI. The revised PAOI will become the new PAOI for purposes of the survey and other communications with residents affected by the proposed traffic calming project.
Distribution of the support survey will be conducted by the City through the mail. The survey will be considered valid if a minimum of 50% of those contacted fill out and return the survey. Staff will then analyze the returns to determine if 67% or more of the PAOI community responding supports proceeding to the final plans, specifications and estimates (PS&E) stage and for the installation of temporary features. Staff will notify by mail all individuals within the PAOI of the survey results and the next steps in the process.
If 50% of the surveys are not returned, an outreach program must be developed by the residents with the assistance of staff. Re-survey will occur after all steps established in the outreach program are completed.
A re-survey will be valid if 50% or more of the surveys are returned to staff. If the plan is not approved by 67% or more of the returned surveys, the residents may choose to develop an alternative plan or abandon their efforts. A revised conceptual plan, after an appropriate outreach program, will be tested by the support survey process in this step. If a conceptual plan fails to garner support of the residents in June 23, 2026

CARLSBAD RESIDENTIAL TRAFFIC MANAGEMENT PROGRAM
16 the PAOI after the second survey, no further surveys will be conducted by city staff for a minimum of one year.
If neighborhood support for the Phase III traffic calming concept plan is established, staff can proceed to Step 8.
Step 8 Environmental Review
Upon confirming the neighborhood support for the Phase I II concept plan and funds have been identified, allocated and approved, staff will initiate environmental review of the proposed project through the City of Carlsbad Planning Department. Generally, traffic calming improvements proposed within the existing street right-of-way are found to be exempt from detailed environmental review.
Step 9 Complete Final Design
Final design of the traffic calming plan can be started by staff concurrent with processing the environmental document. However, the final plan cannot be completed beyond the 30% stage until environmental certification is received and funding for the project is secured. Depending upon the complexity of the final plan, a consultant may be hired by the city. After completion of the final design, staff will initiate installation of temporary measures to simulate the effect of the proposed permanent traffic calming measures. The Police and Fire Departments will have considerable input during the final design.
Step 10 Final Approval by the City Council
The approved Phase III design plan will be brought forward to the Traffic Safety Commission for recommendation and to hear public testimony on the matter. A duly noticed public meeting will be held by the City Council to receive the recommendations of the Traffic Safety Commission for the final traffic calming project and to hear public testimony on the matter. If Council decides the project is acceptable, it will so indicate by adopting a resolution authorizing advertising for construction bids, thus taking the first step toward installation of the project. If, on the other hand, the Council does not support the proposal, staff may be directed to abandon the plan, or to return to the neighborhood for refinement of the plan, or to take no further action.
Step 11 Project Construction
Construction of the approved project, in most cases, will be performed by a licensed contractor selected through the city's formal construction bidding process. After a contractor is selected by the city, individuals within the PAOI will be notified of the construction schedule.
Step 12 Project Monitoring
Traffic calming projects that have been constructed will be monitored for effectiveness during the first year following completion of the installation and also during the second year after the installation.
If residents of the neighborhood believe that the traffic calming measures, impacts and results do not meet their expectations, they may request removal of the permanent measures. The request for removal must follow the Traffic Calming Measures Removal Process and be submitted at least one year from date of Phase III installation.

17 Traffic Calming Measures Removal Process (Phase II and III) Individuals within a neighborhood may determine that one or more traffic calming measures should be removed. If so, a petition favoring removal and signed by 80% of the eligible individuals within the PAOI or expanded PAOI, if applicable, must be sent to staff. Eligibility criteria for signing the petition will be the same as for previously indicated voting procedures (one signature per household or property). A sample petition is provided on the next page for use by the neighborhood contact person to collect signatures.
Staff will review the petition, determine if the 80% threshold is met and notify all residents and non- resident owners within the PAOI of the results. No removal petition will be accepted by staff during the test period when temporary measures are being reviewed.
If the petition has 80% or more valid signatures, it will be submitted to the Traffic Safety Commission for consideration. All individuals within the PAOI will be notified in writing of the meeting and will have the opportunity to address the Commission with their concerns. The Traffic Safety Commission recommendation, whether to deny or sustain the removal petition, will be forwarded to the City Council.
All residents and non-resident owners within the neighborhood PAOI will be notified by mail of the date when the City Council will consider their request for removal of the traffic calming measure(s). Each interested resident will have the opportunity to address the City Council. A final decision will be made by the City Council based upon staff input, Traffic Safety Commission recommendations and citizen comments. As appropriate, staff will initiate action on the City Council's decision. All residents and non- resident owners within the PAOI will be notified of the City Council decision by mail.

19 PROGRAM UPDATE PROCEDURES
It is intended that the Carlsbad Residential Traffic Management Program be dynamic and subject to change. Traffic calming measures, techniques and/or methodologies continue to evolve. What was once in favor and popular to implement may have been subsequently found by agencies to be undesirable, unworkable or unacceptable to the neighborhood.
Revisions to the Carlsbad Residential Traffic Management Program ( CRTMP) are expected. When revisions are suggested, a formal review and approval process of the revision(s) will be followed.
Steps in the revision/update process are as follows:
Step 1 Initiation of Revision
A change or revision may be initiated by the City Council, staff or a citizen. It is suggested that the requested revision be made in writing, with the reasons for or intent of the revision clearly stated. A compelling reason to initiate the update process or to change the process must be offered to be favorably received.
Step 2 Review by Staff
Suggested revisions will be thoroughly researched and reviewed by staff to determine if they are appropriate for inclusion in the Carlsbad Residential Traffic Management Program. Other City departments will also be consulted and, as necessary, comments from stakeholders will be solicited.
Changes to traffic calming measures, procedures or methodologies will only be considered by the Traffic Safety Commission once a year, unless such measures, procedures or methodologies are determined to be illegal.
Step 3 Response to Initiator
Staff will respond in writing to the individual proposing the revisions, commenting on their suitability or requesting additional information as needed. Revisions deemed unacceptable by staff will not be processed further. Revisions recommended by staff for further consideration will be scheduled for discussion at a Traffic Safety Commission meeting. Only those suggested revisions that significantly enhance the overall Carlsbad Residential Traffic Management Program will be considered for acceptance and submitted to the Traffic Safety Commission.
Step 4 Review by the Traffic Safety Commission
All revisions proposed during any 12-month period will be reviewed by the Traffic Safety Commission at the end of such period. The recommendations of the TSC on all such proposed revisions will be forwarded to the City Council. The TSC review meetings will be duly noticed and open to the public for their input on revisions or changes.

20 Step 5 Review and Approval by the City Council
In a public meeting, the City Council will consider the recommendations of the Traffic Safety Commission. Staff may be directed by the Council either to implement the revisions to the program and the supporting documents or to take no action on the requested revision. Noticing procedures for the Council meeting will be the same as for the Traffic Safety Commission meeting and all interested residents will be encouraged to attend the Council meeting to make their opinions known.
Proposed revisions will not interfere with or delay the processing of a neighborhood traffic calming program in progress. A neighborhood that has started development of its traffic calming program will continue the process without change.

21 Measures Not Recommended for Use
Several traffic management measures were evaluated and determined to be unsuitable for use in Carlsbad. Listed following are measures not recommended for installation on public streets and, therefore, not proposed for consideration as part of a neighborhood traffic calming project.
Rumble Strip
A rumble strip is an alteration to the paved street surface by various techniques to draw the driver's attention to a roadway condition. This measure is not acceptable in a residential neighborhood due to the noise and vibration created when a vehicle is driven over the rumble strip.
One-Way Street
A one-way street may encourage increased speeds and may result in additional traffic volumes on a nearby street due to diverted traffic. On a residential street, confusion and wrong-way travel may result as a one-way street is an atypical encounter for drivers when leaving a single-family residence.
Miscellaneous Non-Standard Devices
Signs and/or striping not recognized by the State of California Department of Transportation (Caltrans) as an official traffic control device shall not be used in the public right- of-way. These signs typically include CHILDREN AT PLAY, SLOW and others. Non-official signs are of the novelty type, many have messages that are misinterpreted by drivers, have no legal meaning and their use can expose the City to tort liability. These types of signs do not command the attention or respect of drivers that are repeat users of the street. Using signs that are not officially approved may give a false sense of security to residents. Additionally, the signs raise expectations that some degree of protection is provided through their use when, in reality, this is not the case.
Cul-de-Sacs and Road Closures
Streets have been designed and constructed to facilitate multiple points of egress for the residents and multiple ways for an emergency vehicle to respond to an incident. Basic circulation patterns are intended to remain. Streets will not be truncated through the construction of a barrier to cause a road closure or by converting the end of the street into a cul-de-sac through construction of a turnaround.

TRAFFIC CALMING TOOLBOX
Traffic control devices are those official signs and striping placed in the public right- of-way and recognized by the public such as STOP signs, curve warning signs, centerline striping, etc. These devices have been officially approved by the State of California Department of Transportation (Caltrans) pursuant to legislative authority provide for in the California Vehicle Code.
Traffic calming measures, however, have evolved to include features that may not be officially approved through legislative action by the State of California. Commonly referred to as “tools”, the traffic calming measures or features available for use in Carlsbad are available in this program’s “toolbox”.
Each tool listed is unique and has a specific purpose for addressing residential street traffic concerns that require some form of traffic calming. Each tool has its own set of advantages and disadvantages and a range of costs. More than just a structural feature on a street, traffic calming tools also encompass education, enforcement, engineering and enhancement.
The following pages identify tools that have been endorsed and available for use in Carlsbad.
They were chosen for:
Appropriateness to address traffic concerns in Carlsbad.
Acceptability to stakeholders including the Fire and Police Departments.
Suitability for use in residential neighborhoods.
Each traffic calming measure is briefly described, application for usage listed, and possible advantages and disadvantages outlined. Estimated costs have been provided when the cost of the measure was able to be determined.

This measure is one of the least acceptable to the Fire Department and Police Department; its use requires extensive evaluation of the specific location and impacts to emergency response times.
Cost:
$14,000 to $28,000 each.

Phase III
Semi-Diverter
Description:
Semi-diverters are curb extensions that
restrict movements into a street. They are
constructed to approximately the center of
the street, obstructing one direction of traffic.
A one -way segment is created at the
intersection, while two -way traffic is
maintained for the rest of the block.
Application:
Semi-diverters reduce traffic volume.
Advantages:
Reduces cut-through traffic.
More self-enforcing than signs.
Reduces pedestrian crossing widths.
Opportunity for landscaping.
Disadvantages:
May divert traffic to other streets.
May increase trip lengths.
May require the removal of parking.
Increased maintenance.
Special Considerations:
Restricts access into street while allowing residents access within block.
Potential use must consider how residents will gain access.
In emergency situations, emergency vehicles can gain access.
May increase emergency response times.
Fire Department and Police Department Evaluation:
This measure is one of the least acceptable to the Fire Department and Police Department; its use requires extensive evaluation of the specific location and impacts to emergency response times.
Cost:
$20,000 to $28,000 each.

Phase III
Partial Diverter
Description:
Partial diverters are raised areas placed
diagonally across a f our-legged
intersection (3/4 closure). They prohibit
through movements by creating two "L"
shaped intersections, with one leg having
a right turn.
Application:
Partial diverters help reduce cut -through
traffic. They also minimally decrease
speeds near the intersection.
Advantages:
Reduces cut-through traffic.
Minimal impact to emergency access.
Reduces collision potential.
Opportunity for landscaping.
Disadvantages:
Redirects traffic to other streets.
May increase trip lengths.
Special Considerations:
Problem(s) may be shifted to other streets unless a comprehensive area plan is developed.
Less impact to circulation than a full street closure.
Can be attractively landscaped.
Fire Department and Police Department Evaluation:
This measure is one of the least acceptable to the Fire Department and Police Department; its use requires extensive evaluation of the specific location and impacts to emergency response times.
Cost:
$20,000 to $48,000 each.

Phase III
Diagonal Diverter
Description:
Diagonal diverters are raised areas placed
diagonally across a four -legged intersection.
They prohibit through movements by creating
two "L" shaped intersections.
Application:
Diagonal diverters reduce traffic volumes.
They also mini mally decrease speeds near the
intersection.
Advantages:
Reduces cut-through traffic.
Self-enforcing.
Reduces vehicle conflicts.
Opportunity for landscaping.
Disadvantages:
Increases out of direction travel.
Increases trip lengths.
Impedes emergency vehicles.
Special Considerations:
Can be designed to allow emergency vehicle access.
Can be designed to allow pedestrian and bicycle access.
Problem(s) may be shifted to other streets unless a comprehensive area plan is developed.
Less impact to circulation than a full street closure.
Fire Department and Police Department Evaluation:
This measure is one of the least acceptable to the Fire Department and Police Department; its use requires extensive evaluation of the specific location and impacts to emergency response times.
Cost:
$25,000 to $52,000 each.

re: Continuing Unicornio Dangerous Condition Matter
Carlsbad Traffic and Mobility Management:
I wrote to you not less than Eighteen (18) years ago in regards to this exact serious concern. (see attached letter to Murray dated Nov 01, 2008) And many , many times since. Unicornio residents have suffered constant and repeating unsafe conditions in the form of reckless and lawless speeding vehicles, countless near misses, and multiple serious collisions on Unicornio Street. Particularly on the section located between El Fuerte Rd. and Rancho Cortes Street.
My files of communications, statistics, and endless empty promises from the City of Carlsbad occupy several 3-inch thick binders and gigabytes of stored electronic data.
The City’s obvious and blatant lack of concern for the unsafe and dangerous conditions on our street are clearly documented and of record.
The written communication paper trail for these problematic years speaks volumes.
The residents of Unicornio Street have followed the City’s prescribed process to achieve effective and lasting traffic control through nearly 100% involvement and personal participation. We have been beyond reasonable and patient whilst the City has delayed, procrastinated, made empty promises and blown through the city’s self generated action dates.
We are collectively exasperated with cars and trucks driving at very high rates of speed at all hours and with little regard to pedestrians, bicyclists, and residents attempting to enter / exit their respective driveways.
V ehicles passing each other at speeds greater than 50 mph are a regular occurrence.
Further, it is not uncommon for a following vehicle to actually pass residents on the left while the resident is actually TURNING LEFT into their own driveway . It happens frequently and sometime accompanied by horns and finger gestures.
Promises of enhanced police enforcement have not materialized. Unicornio is ‘open season’ for speeding and dangerous driving with virtually zero consequence to the offending driver(s).
Y ears were consumed to eventually have 25mph Seed Limit signs and road surface appliqués installed, yet their net effectiveness is less than dismal.
Near miss accidents and honking horns at the intersection of Unicornio / Cacatua are the norm. So is being awoken in the late hours of the night by vehicles speeding down Unicornio at bold and excessive rates of speed.
Y et again this recent week saw ANOTHER vehicle collision on Unicornio.
When will the city finally perform the speed control and traffic calming promises it has made to our neighborhood ?
Sincerely ,

Re: Your Letter of June 12, 2008
Subject: Unicornio Street Vehicle Speeding - Unsafe Condition Concerns Matter Dear Jim:
I offer my sincere appreciation for your detailed and comprehensive response to my original letter of concern early this recent summer. I was encouraged that you, your engineering department, and the CPD were "all over" this unsafe condition and an effective corrective action plan implementation was immanent.
However, it is now November 2008 and there appears to be no change to report to you.
I have not noticed any new speed limit signs or pavement lettering installed. Nor have I noticed any significant patrol enforcement activities.
Speeding and reckless driving continues. I recently observed what can only be described as the 'closest of calls' of a broadside collision between two vehicles at the comer of Unicornio and Cacatua with the Unicornio Mercedes traveling at least 60 mph and the Cacatua BMW SUV proceeding with a left turn without slowing directly into the path of the speeding Mercedes. The 15 foot long skid marks are still on the pavement.
It is my experience that it is not uncommon to be subjected to hostility and gestures from faster ( usually same direction passing) drivers when I am driving @ 25 mph along Unicornio.
Further, the practice of indiscriminate high speed passing slower vehicles on Unicornio by vehicles primarily travelling from the Rancho Cortes street direction continues.
Again, the 60 foot unmarked width ofUnicomio Street, combined with residences on only one side, and, in conjunction with being void of center line graphics or markings all only serve to present a perception that drivers are travelling a uncontrolled (i.e.: drag strip) section of roadway. Many drivers appear to drive as if they believe there are no rules that apply to Unicornio Street traffic.
As you suggested I have attempted to copy license plate information from some speeding vehicles, but this has been impractical due to the speeds involved, and, I am not comfortable following the offenders to their driveway due to the sometimes aggressive stance many seem to possess.
I continue to trust this matter will be properly addressed, Stephen & Deborah Nash

UNICORNIO STREET SPEEDING CONCERNS
The purpose of this letter is to follow-up to your letter to the Engineering and Police Departments regarding your concerns about speeding on Unicornio Street between El Fuerte Street and Rancho Cortes. You have requested implementation of a corrective action plan and police enforcement of the posted 25 mph speed limit.
I have included a copy of the Carlsbad Residential Traffic Management Program (CRTMP), which contains the city's policies and procedures dealing with the issues of speeding and cut through traffic on residential streets in the City of Carlsbad. It is a three phase program being with Phase I, which deals with traffic calming strategies and less-restrictive engineering solutions indicated as Phase I tools in the toolbox. Read the document through focusing on Phase I, and call me with any questions you may have.
In addition to the Phase I tools in the CRTMP Toolbox, there are a couple of other things you can do to address speeding concerns. You can call Lt. Don Rawson in the Traffic Division of the Carlsbad Police Department at (760) 931-2208, and request installation of the Speed Sentry.
The Speed Sentry is a device that can be installed for a few days on any street light standard that records the speed of each approaching vehicle and provides data printout sheets. The Speed Sentry can be set to one of two modes, each having a different function. When set to a blank screen/stealth mode, it is being used to obtain speed data (drivers display their most typical driving behavior in blank screen/stealth mode). When set to display screen, it is being used as an educational device, to make drivers aware of their current speed and hopefully choosing to slow down if speeding. Data obtained when the Speed Sentry is set to display screen does not represent driver's most typical behavior. Some drivers will slow down when they see the display screen.
Another option available is the Police Department's Neighborhood Speed Monitoring Program.
If you or your neighbors can write down the license plate number of any vehicle you observe to be speeding, you can call it in to Lt. Rawson along with the date, time, and approximate location. The police will run the license plate through DMV and will send a letter to the registered owner of the vehicle. The letter informs the owner that the vehicle was observed to be speeding on Unicornio Street on the specified date and time, that residents are very concerned about speeding, and to please observe the 25 mph speed limit on Unicornio Street. 1635 Faraday Avenue• Carlsbad, CA 92008-7314 • (760) 602-2720 • FAX (760) 602-8562 @ June 12, 2008
UNICORNIO STREET SPEEDING CONCERNS
The letter states that this information will be kept on file and if another speeding complaint is received a uniformed officer will go to their residence to discuss it with them.
Staff field reviewed the existing conditions on Unicornio Street between El Fuerte Street and Rancho Cortes. This segment of Unicornio Street is 40 feet wide curb to curb and meets the California Vehicle Code definition of a RESIDENCE DISTRICT which has a prima facie speed limit of 25 mph. As you mentioned, there is an existing "SPEED LIMIT 25" sign installed on the street light standard for northbound traffic located on the northeast corner at Xana Way.
However, there is no speed limit sign posted for southbound traffic on this segment of Unicornio Street. A work order has been issued to install a new "SPEED LIMIT 25" sign for southbound traffic on Unicornio Street south of Rancho Cortes. This will serve as a reminder to drivers of the 25 mph speed limit on this residential street. In addition, the existing "SPEED LIMIT 25" sign for northbound traffic located on the northeast corner of Xana Way will be relocated to the first street light on Unicornio Street north of El Fuerte Street for northbound traffic. This should improve visibility of this speed limit sign for northbound drivers on Unicornio Street.
Thank you for your concerns regarding traffic safety and for your patience while staff conducted the field studies needed to address and evaluate your concerns. If you have any questions, or want to discuss this further, please give me a call at (760) 602-2734. ~YlA-Y

City Council Members,
Living on 3006 Unicornio St. for 38 years I have seen traffic racing down the street way over the Speed Limit. It seems to start at El Fuerte or before and end in Carrillo Ranch while making a left turn. We have seen accidents or near accidents several times. The most recent one in front of our home was a driver crashing his car and severely damaging the car parked in front of my house in the middle of the night and also destroyed our mailbox landing across the sidewalk and on to our lawn.
My next door neighbors front yard and windows in front of his house were broken after making a wrong turn into the driveway. This happened about two months ago and you should have a report on that as well.
Many cars
race by everyday.
I believe we need more than two bumps on this street. Many times I will see cars coming around the corner of Xana way well over the limit as well as from the cars coming out of Carrillo. We need at least three bumps or even four
to be safe. One close after turning on to Unicornio St. from Carrillo and another near half way to Unicornio St and Xana Way
and another near the intersection of Xana Way
and
El Fuerte St.
There was another severe accident at the corner of Unicornio St.and El Fuerte St. just about 2 weeks ago.
Our street black top has been changed only one time in the 38 years we have lived there and that was because I called to complain and someone came out to see it and it was finally redone about a year later. I have seen other streets both at the other end of Unicornio St.
and those on and off of Corinthia have the black top done 4 times.
We have pebbles all over Unicornio St. while every other street in our area had it done, once again less than one year ago.
Please tell us why we have not
been treated so much more like
all the other streets near by!
We are out of town this week and are unable to be at Tuesdays meeting but I am sure some others will be there to ask and answer questions.
Please make sure
this letter will be read at the meeting on Tuesday.
Thank you for listening.

TRAFFIC CALMING UNICORNIO STREET
City Council Meeting
Tuesday June 23 2026 5:00 pm
Unicornio residents have been literally begging the city of Carlsbad to address the continuous unsafe condition of vehicular safety for eighteen years.
We have endured multiple accidents resulting in significant property damage as recently as earlier this month.
Vehicles traveling at high rates of speed make it challenging to simply depart or enter our driveways. Near misses, honking horns, finger gestures, and more are a regular occurrence.
The many promises made by the city for timing, analysis, and corrective action remain unfulfilled. The results of the speed-evaluation process the city has employed are less than accurate and do not reflect what has become the norm for vehicle traffic on Unicornio Street between El Fuerte and Rancho Cortes streets.
Residents on our street include Lawyers, Real Estate professionals, Engineers, and other honorable professionals. We have conducted multiple private speed studies employing calibrated doppler radar equipment and the results speak for average and top speeds well above any of the results published by the city. The statistical results of our private studies are available for any interested party to review.
The majority of the offending drivers appear to originate from the Carrillo development and they regularly treat our street as a Freeway thoroughfare connector to get onto the main streets (such as Alga Rd) as fast as possible. It is not lost on us that somehow, the Carrillo Way street received expedited approval for the installation of SIX speed cushions on a street that is winding and naturally calming to traffic, yet after YEARS of significant efforts by Unicornio residents we have only garnered interim approval for TWO cushions.
Further, in the special meeting in October 2025, we were told the reason for only two cushions directly related to the need for unfettered emergency vehicle traffic flow - Fire / Ambulance / etc. Yet, looking to the city letter of April 7, 2023 regarding the approval of six cushions on Carrillo Way, the issue of emergency traffic is clearly carved-out as a non-issue. This fact begs the question of why a street section of similar length and width (Carrillo Way) receives a fast turn- around approval for six cushions whilst Unicornio is offered only two cushions in spite of a 90% resident request asking for four cushions ? That decision together with the installation of the multiple speed cushions on Carrillo Way only made the speeding traffic on Unicornio worse by increasing the number of vehicles avoiding the Carrillo Way speed cushions.
We are all fortunate we have not endured an incident resulting in significant injury or worse. History shows there have been some very close calls - all directly related to the uncontrolled traffic behavior of drivers traveling Unicornio.
It is far past time that the city expedites the installation of effective traffic calming features, and, hopefully more than just two speed cushions …. the safety of our family, children, walkers, joggers, cyclists, pets, and more is hanging in the balance.
Please do the honorable thing and get this problem handled in a time is of the essence manner.

RE: 3100 Block of Unicornio St - Resurfacing Update
To: Stephen Nash, Cc: Cight
Thomas and Stephen -
An update tor both of you.
November 25, 2024 at 4:10 PM
Details
Unfortunately, I was unable to get your street segment (3100 Unicornio) added to the scope of the resurfacing project taking place on nearby streets.
That's the bad news.
The good news is that City of Carlsbad will be co
Unicornio/Xana and Unicornio/Cacatua where
ting area repairs to the two areas near the T-intersections of e is loose pavement and gravel.
You should see City crews out on y r
pavement markings for the repair
before end of First Week December taking measurements and making I expect for the crew to have repairs complete before the new calendar year.
The long-term fix is to perform full resurfacing on your 3100 block of Unicornio (between Rancho Cortes and El Fuerte, including the Xana Wy Cul-de-Sac). Your block has been added to the 2025 resurfacing project, targeting a construction date during the Last Half of 2025.
As before, you can reach me at my number below, don rt potentially hazardous pavement conditions using the Carlsbad Connects App, Available on iOS and Andro1 https://www.carlsbadca.gov/residents/re12ort-a-problem/carlsbadconnects -Edd ie Wills
