Q^^^^ 1998 Rancho Santa Fe Road Project • Acoustical Assessment Report City Of Carlsbad SUMMARY Noise sensitive receivers in the project vicinity include four residences located along the western portion of the project site along Rancho Santa Fe Road and approximately six residences located at the intersection of Melrose Drive and Corintia Street. Future noise levels generated by project traffic from the proposed road widening would exceed the Federal Highway Administration and California Department of Transportation's noise criteria at the four homes located along Rancho Santa Fe Road. A noise barrier constructed along the western right-of-way of Rancho Santa Fe Road, south of Meadowlark Ranch Road, would be required to mitigate the noise impact at the single family residences. Noise unpacts at the remaining residences and adjacent land uses would be less than significant. &ASSOCIATES X cn/.,.,. c.„.,.,,.. octotjer 26, 1998 Rancho Santa Fe Road Project • Acoustical Assessment Report City Of Carlsbad 1.0 INTRODUCTION This noise study is provided for the proposed Rancho Santa Fe Road Bridge Replacement project. The proposed project is located within the City of Carlsbad and City of San Marcos. The City of Carlsbad is the lead agency for the project. The project would also be federally funded, therefore, Caltrans is a responsible agency. This study documents the existing noise level based on noise measurement and modeling. The future noise levels were calculated based on the proposed project's roadway design and traffic volume conditions. Noise sensitive receivers were identified and noise barriers have been evaluated where necessary to achieve applicable noise criteria. 2.0 PROJECT DESCRIPTION 2.1 Project Location and Setting The project site is located near the southeastern portion of the City of Carlsbad. The regional project location is depicted in Figure 1 and the project vicinity is shown in Figure 2. The area of potential effect associated with the project includes an approximate 450 linear foot distance along Rancho Santa Fe Road immediately south of Meadowlark Ranch Road. The engineering design along this 450-foot section of road was completed by the City of San Marcos as part of a separate road widening project. Adjacent to the project site are an industrial business park, undeveloped land and approximately ten residences located within two residential areas. One residential area is located along the western portion of the site near the intersection of Melrose Drive and Corintia Street. These residences are located within the City of Carlsbad. The second residential area consists of four homes located on the west side of Rancho Santa Fe Road immediately south of Meadowlark Ranch Road. These homes are located within the County of San Diego. An acoustical study was prepared evaluating noise impacts along this section of road as part of the City of San Marcos' Rancho Santa Fe Road widening project (RECON 1998). 2.2 Project Characteristics The City of Carlsbad's proposed Rancho Santa Fe Road improvement and bridge replacement project would realign and widen approximately 3,500-linear feet of Rancho Santa Fe Road (S-10) from two wmm &ASS0C1ATES October 26, 1998 Orange County San Diego Mexico 1" -8 Miles Tijuana Rancho Santa Fe Road Bridge Replacement - Acoustical Assessment Report Regional Map FIGURE BASE MAP SOURCE: USGS 7.5 Minute Series, Rancho Santa Fe Quadrangle 1"-2000' Rancho Santa Fe Road Bridge Replacement - Acoustical Assessment Report Vicinity Map FIGURE Rancho Santa Fe Road Project • Acoustical Assessment Report City Of Carlsbad lanes to an ultimate six-lane Prime Arterial Roadway from just south of Questhaven Road to just north of Melrose Drive in northern San Diego County. Roadway Realignment The proposed widening and realignment project is part of the City of Carlsbad's General Plan to upgrade Rancho Santa Fe Road to meet its designation as a Prime Arterial Roadway. A Prime Arterial Roadway has a 126-foot right-of-way containing six travel lanes, a bike lane, an 18-foot raised median, sidewalks, curb, and gutter. The new bridge over San Marcos Creek is planned to accommodate the Prime Arterial Roadway. The bridge replacement project would involve construction of a new bridge in a location west of the existing bridge. The existing bridge will be demolished: The northerly roadway approach for the new bridge(s) wiU be approximately 2,200 feet long and includes the reconstruction of the La Costa Meadows Drive/Rancho Santa Fe Road intersection, and reconstruction of approximately 300 feet of La Costa Meadows Drive east of the intersection. The realigned Rancho Santa Fe Road wiUbe constructed to the full width on the east side of the median, with sidewalks, curb and gutter, and street lights from the bridge to north of Melrose Drive. The west side of the roadway will be constructed with 32 feet of paving adjacent to the median curb. The current alignment of Melrose Drive would be altered to accommodate the proposed widening of Rancho Santa Fe Road. The Melrose Drive/Rancho Santa Fe Road intersection would be moved approximately 400 feet to the north of the present intersection. Melrose Drive would be realigned from the Corintia Drive/Melrose Drive intersection where Melrose Drive would extend to the northwest to the realigned Melrose Drive/Rancho Santa Road intersection. Corintia Drive would be extended east to cormect with the realigned Melrose Drive. 3.0 NOISE CRITERIA This report follows the noise criteria and policies established by the City of Carlsbad, County of San Diego, as well as the California Department of Transportation (Caltrans) and the Federal Highway Administration (FHWA). These guidelines establish procedures for noise studies regarding traffic noise prediction, noise analyses And noise abatement criteria. The proposed project is located within portions of the City of Carlsbad, County of San Diego and City of San Marcos. The City of Carlsbad and the County of San Diego noise criteria are applied within the applicable local jurisdiction area. Caltrans and FFIWA noise criteria are also used for land &ASS0C1ATBS A CtUf.rnU Cirft, October 26, 1998 Rancho Santa Fe Road Project • Acoustical Assessment Report City Of Carlsbad uses adjacent to Rancho Santa Fe Road and where Rancho Santa Fe Road is the predominant noise source. There are no noise sensitive receivers along the project site that are located within the City of San Marcos. The City of Carlsbad describes community noise levels in terms of the Community Noise Equivalent Level (CNEL). The CNEL is a 24-hour average A-weighted sound level with a ten decibel (dB) "penalty" added to noise during the hours of 10:00 p.m. to 7:00 a.m., and a five dB penalty added to the evening hours of 7:00 p.m. to 10:00 p.m The five and ten dB penalties are applied to account for increased noise sensitivity during the evening and nighttime hours. The A-weighted scale measures noise levels corresponding to the human hearing frequency response. AU sound levels in this report are A-weighted. Noise levels at residences immediately adjacent to Rancho Santa Fe Road were also evaluated in terms of the peak hour average sound level. The peak hour average sound level is the noise descriptor typicaUy used by the FHWA and Caltrans when evaluating traffic noise. 3.1 City Of Carlsbad Noise Criteria The City of Carlsbad requires that the maximum acceptable exterior noise level for new residential development shaU not exceed a CNEL of 60 dB. 3.2 County Of San Diego Noise Criteria The County of SanDiego's maximum acceptable exterior noise level for new residential development is that the CNEL should not exceed 60 dB. However, projects that are federaUy funded are to comply with appUcable FFIWA standards. 3.3 FHWA/Caltrans Noise Criteria The FHWA foUows the noise abatement procedures estabUshed in the Code of Federal Regulations (23 CFR 772). Caltrans also foUows the noise abatement procedures as weU as poUcies estabUshed in Caltrans Highway Design Manual Chapter 1100. The FHWA noise abatement criteria categorizes different activities and land uses for the purposes of assessing noise impacts. Table 1 shows the FFIWA noise abatement criteria. The criteria are based on the peak hour (noisiest) average sound level which regularly occurs during a 24-hour period. The noise abatement criteria for outdoor noise exposure typicaUy is appUed where frequent human use occurs such as swimming pools and common use areas at multi-family residences and the backyards of single family homes. ili &ASSOCIATES October 26, 1998 Rancho Santa Fe Road Project • Acoustical Assessment Report City Of Carlsbad TABLE 1 Noise Abatement Criteria Hourly A-Weighted Average Sound Level - decibel [dBJ' Activity Category Uh) Lio(h) Description of Activ'tfy Category A 57 (Exterior) 60 (Exterior) Lands on which serenity and quiet are of extraordinary significance and serve an important public need and where the preservation of those qualities is essential if the area is to continue to serve its intended purpose.

Either Lio(h) or Leq(h) (but not both) may be used on a project. The FFIWA considers that a traffic noise impact occurs when the predicted traffic noise levels approach or exceed the Noise Abatement Criteria. The FHWA specifies that the Noise Abatement Criteria, when approached or exceeded, requires the consideration of traffic noise abatement measures. The FHWA indicates that local State Highway Agencies should use a definition of approach that is at least one dB less than the Noise Abatement Criteria. Caltrans defines approach as being two dB lower than the Noise Abatement Criteria. 4.0 METHODOLOGIES AND INSTRUMENTATION To determine the existing noise levels and potential noise impacts, a 24-hour and short-term noise measurement were conducted adjacent to the project site. The 24-hour noise measurement was made to determine the peak hour average noise level associated with traffic noise from Rancho Santa Fe Road, and to determine the CNEL. Noise modeling was also conducted using Caltrans' SOUND32 traffic noise prediction model (Caltrans 1983). The SOUND32 noise model accepts as input the DUDEK &ASSOCtATES A C.hl.r.l. Ctftt October 26, 1998 Rancho Santa Fe Road Project • Acoustical Assessment Report City Of Carlsbad number and types of vehicles on the roadway, vehicle speeds, and physical characteristics of the road and topography; as weU as receiver and noise barrier heights and locations. The CALVENO vehicle noise emission levels were used in the noise model (Caltrans 1987). The noise measurements were conducted using caUbrated Larson-Davis Laboratories Model 700 (S.N. 2132) and Model 712 (S.N. 0231) digital integrating sound level meters. The sound level meters meet the current American National Standards Institute standard for a Type 1 (Model 700) and Type 2 (Model 712) sound level meters. Traffic counts were made during the short-term noise measurement. The truck percentage used in the noise model was 3.52% medium trucks and 1.24% heavy trucks for Rancho Santa Fe Road. The truck percentage used for Mekose Drive was 1.83% medium trucks and 0.28% heavy trucks. The truck percentages are based on vehicle mix surveys conducted by the City of Carlsbad (City of Carlsbad 1995). To verify the input used in the noise model, the same traffic volume and vehicle composition ratios counted during the noise measurements were used. The posted speed Umit for both Rancho Santa Fe Road and MeUose Drive is 45 miles per hour. This speed correlated weU with the results of the noise measurement and were used in the noise modeUng for these roads. The modeled values were within 1 dB of the measured noise levels which confirms the assumptions used in the noise model. 5.0 EXISTING CONDITIONS Site A, as depicted on Figure 3, was monitored from 11:00 a.m. on Tuesday, July 15, 1997 to 11:00 a.m. on Wednesday, July 16, 1997. The primary noise source at the measurement site is traffic on Rancho Santa Fe Road. Site A was selected to provide an unobstructed view of the Rancho Santa Fe Road (i.e., no intervening waUs, buUdings, topography etc.). Table Z depicts the hourly average sound levels during the measurement period at Site A. The peak (noisiest hour) average noise level was 70 dB and occurred both during the morning commute and the evening commute hours. A short-term noise measurement was also conducted at the residential area located at the northwest intersection of Mekose Drive and Corintia Street (Site B, Figure 3). The traffic noise at these residences is primarUy associated with Mekose Drive, and to a lesser extent, Rancho Santa Fe Road. The homes at this area have existing sound waUs approximately 5 to 6-feet in height. The noise measurement, conducted approximately 10 feet in front of the sound waUs resuked in an average sound level of 63 dB. The traffic noise level fiom Rancho Santa Fe Road was observed to typicaUy range from 52 to 58 dB at Site B.

The noise modeUng included the future year 2015 traffic information and the physical improvements shown on the preliminary designs for the road widening and intersection improvements. The future year 2015 "not buUt" traffic volumes and existing roadway constituted the "no build" scenario. The future year 2015 buUt scenario included the buUt traffic volumes as weU as the proposed roadway improvements. With implementation of the proj ect, the future peak one-hour average noise level is proj ected to reach approximately 71 dB at the backyards of the residences located along the west side Rancho Santa Fe Road and south of Meadowlark Ranch Road (Sites 4, 5, and 6 on Figure 3). This noise level would exceed Caltrans/FHWA noise abatement criteria. These are the only residences located adjacent to Rancho Santa Fe Road that are within the project limits. Tabk 4 shows the existing, predicted future "buUt" and future "not buUt" peak one-hour average noise levels at the receivers. The future peak hour average noise level at the residences located along Melrose Drive would range from approximately 60 to 64 dB. The future noise levels at these residences would be similar with or without the project. This noise level would comply with the FFIWA noise abatement criteria. DUDEK &ASS0C1ATES A Cillf.rHl.

This includes the noise attenuation associated with the existing five to six-foot high sound waU at the residences. The CNEL would be approximately one dB greater than the peak hour average noise level. The noise level increase would primarily result from future traffic growth along Melrose Drive rather than noise impacts associated with the project. As indicated in the preliminary design plans for the project, Mekose Drive would be aUgned farther away from the homes near the intersection of Mekose Drive and Corintia Street. The future noise level at the homes located near the intersection would be approximately one dB lower with the project as compared to the not buUt scenario. The noise impact associated with the project at these homes would be less than significant. The business industrial park includes several outdoor lunch areas. Most of the lunch areas are located along the east sides of the buildings which provide noise attenuation from the traffic noise. However, a lunch area is located on the south side of the southern most building in the industrial complex. The peak one-hour average noise level at this location would be approximately 66 dB. This noise level compUes with the FFIWA/Caltrans noise criteria. mmmm &ASSOCIATES A C.lll.Tnl.

The faciUty is partiaUy shielded from traffic noise by intervening buildings. The future peak hour average noise level at this location would be approximately 62 dB. This noise level would comply with the FHWA/Caltrans noise criteria. 7.0 MlTIGATIGN Future noise levels would exceed FHWA/Caltrans noise criteria at four homes located along Rancho Santa Fe Road. PreUminary mitigation measures for the affected homes have been evaluated to provide noise abatement and design information. With an eight-foot high sound waU located along western right-of-way, the future peak hour average noise level would be mitigated to 61 to 62 dB. The location of the proposed noise barrier is depicted on Figure 4- A comparison of the noise reduction provided by various barrier heights is shown in Table 5. It should be noted that an eight- foot high sound waU is depicted in the engineering design plans as part of the City of San Marcos' Rancho Santa Fe Road widening project. The eight-foot waU height shown in the engineering design plans is based on the acoustical assessment prepared for the City of San Marcos. Assuming the City of San Marcos constructs this segment of Rancho Santa Fe Road, the City of San Marcos wiU construct an eight-foot high sound waU at these residences. If the City of Carlsbad constructs the proposed project first, the City of Carlsbad has committed to constructing the noted sound waU proposed by the City of San Marcos (City of Carlsbad 1998).
