March 2001 Rancho Santa Fe Road Project • Acoustical Assessment Report SUMAAARY Existing 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, will be constructed by the City of Carisbad as part of the proposed proj ect to reduce the noise impact at the single family residences. It is possible that the City of San Marcos will construct this section of Rancho Santa Fe Road north of Melrose Drive. If the City of San Marcos constructs this segment, the City of San Marcos would construct the noted noise barrier. Noise impacts at the remaining existing residences within the proj ect study area and adj acent land uses would be less than significant. A single family development named the Meadowlands proj ect is currently under construction at the northwest intersection of Rancho Santa Fe Road and Melrose Drive. As a condition of approval for the Meadowlands project, noise barriers are to be constructed by the developer at the homes adjacent to Rancho Santa Fe Road and Melrose Drive. The height and locations of the noise barriers are based on an acoustical study prepared for that project. March 2001 Rancho Santa Fe Road Project • Acoustical Assessment Report 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 CityofCarlsbad. The regional project location is depicted in Figure 1 and the project vicinity is shown in Bgure Z. 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). In addition, lots for single family residences for the Meadowlands project are currently being graded near the northwest intersection of Rancho Santa Fe Road and Melrose Drive. An j&A^pCIATES. INC.

A m Prime Arterial Roadway has a 126-foot right-of-way containing six travel lanes, bike lanes, to 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 demohshed. *w The northerly roadway approach for the new bridge (s) will 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 cast ~ of the intersection. The realigned Rancho Santa Fe Road will be 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. m 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 cast to connect with the realigned Melrose "* Drive. The potential exists that the City of San Marcos may construct some improvements. However, for the purposes of the analysis conducted for this report it is assumed that these m roadway improvements would be constructed by the City of Carlsbad. March 2001 m m m m Rancho Santa Fe Road Project ^ Acoustical Assessment Report ^ 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 CaUfornia 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 FHWA noise criteria are also used for land 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 (dBA) "penalty" added to noise during the hours of 10:00 p.m. to 7:00 a.m., and a five dBA penalty added to the evening hours of 7:00 p.m. to 10:00 p.m. The five and ten dBA 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. All 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 noise peak hour average sound level is the noise descriptor typically 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 shall not exceed a CNEL of 60 dBA. 3.2 County of San Diego Noise Criteria The County of San Diego's maximum acceptable exterior noise level for new residential development is that the CNEL should not exceed 60 dBA. However, projects that are federally funded are to comply with applicable FHWA standards. March 2001 Rancho Santa Fe Road Project • Acoustical Assessment Report m m m m m 3.3 FHWA/Caltrans Noise Criteria The FHWA follows the noise abatement procedures estabhshed in the Code of Federal Regulations (23 CFR 772). Caltrans also follows the noise abatement procedures as well as policies established 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 i shows the FHWA 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 typically is applied where frequent human use occurs such as swimming pools and common use areas at multi-family residences and the backyards of single family homes. TABLE 1 Noise Abatement Criteria Houriy A-Weighted Average Sound Level - decibel (dBA) Activity Category LJh) — : Description of Activity Category A 57 (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. B 67 (Exterior) Picnic areas, recreation areas, playgrounds, active sports areas, parks, residences, motels, hotels, schools, churches, libraries and hospitals. C 72 (Exterior) Developed lands, properties, or activities not included in Categories A or B above. D — Undeveloped lands. E 52 (Interior) Residences, motels, hotels, public meeting rooms, schools, churches, libraries, hospitals and auditoriums. The FHWA considers that a traffic noise impact occurs when the predicted traffic noise levels with project approach within 1 dBA, or exceed the Noise Abatement Criteria. The FFIWA specifies that the Noise Abatement Criteria, when approached or exceeded, requires the consideration of traffic noise abatement measures. March 2001 ii m m m ii Rancho Santa Fe Road Project • Acoustical Assessment Report 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 number and t3^es of vehicles on the roadway, W vehicle speeds, and physical characteristics of the road and topography; as well 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 calibrated 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 Melrose 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 Cadsbad (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 limit for both Rancho Santa Fe Road and Melrose Drive is 45 miles per hour. This speed correlated well with the results of the noise measurement and were used in the noise modeling for these roads. The modeled values were within 1 dBA of the measured noise levels which confirms the assumptions used in the noise model. 5.0 EXISTING CONDITIONS Site A, as depicted onFigureS, 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 walls, buildings, 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 dBA and occurred both during the morning commute and the evening commute hours. ^rajirtWwM TWiiM^<HHw|>i« ^^^^^ March 2001 Q Noise Measurement Location O Noise Modeling Receptor PROJBn'GRADMG SOUItCB Dojdcm^&^neertn^^gM^^ Scde in Feet Rancho Santa Fe Road Bridge Replacement ^Acoustical Assessment Report .

The traffic noise at these residences is primarily associated with Melrose Drive, and to a lesser extent, Rancho Santa Fe Road. The homes at this area have existing sound walls approximately 5 to 6-feet in height. The noise measurement, conducted approximately 10 feet in front of the sound walls resulted in an average sound level of 63 dBA. The traffic noise level from Rancho Santa Fe Road was observed to typically range from 52 to 58 dBA at Site B. Tahle 3 depicts the results of the noise measurement adjacent to Melrose Drive.

An acoustical study prepared for that project identified noise impacts exceeding the City's noise criteria for approximately 25 residential lots located adjacent to Melrose Drive and Rancho Santa Fe Road (Segal 1985). Noise barriers were recommended in the acoustical study to mitigate the noise impact to meet the City's applicable noise criteria at the time the development permit appHcation was approved (i.e., 65 dBA L^j. This noise level would comply with FHWA/Caltrans noise criteria. As part of the City's conditions of approval for the Meadowlands project, the developer has built the noise barriers at the residential lots adjacent to Rancho Santa Fe Road and Melrose Drive. March 2001 10 Rancho Santa Fe Road Project • Acoustical Assessment Report 6.0 FUTURE CONDITIONS To determine future noise levels and the significance of potential noise impacts at land uses adjacent to the project site, future year 2015 "built" and future year not built noise levels were calculated using the SOUND32 model. The noise modeling 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 built" traffic volumes and existing roadway constituted the "no build" scenario. The future year 2015 built scenario included the built traffic volumes as well as the proposed roadway improvements. With implementation of the project, the future peak one-hour average noise level is projected to reach approximately 71 dBA 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/FFIWA noise abatement criteria. These and the recently constructed Meadowlands project discussed in the previous section, are the only residences located adjacent to Rancho Santa Fe Road that are within the project limits. Tahle 4 shows the existing, predicted future "built" and future "not built" peak one-hour average noise levels at the receivers.

March 2001 11 Rancho Santa Fe Road Project • Acoustical Assessment Report The future peak hour average noise levei at the residences located along Melrose Drive would range from approximately 60 to 64 dBA. The future noise levels at these residences would be similar with or without the proj ect. This noise level would comply with the FHWA noise abatement criteria. The peak hour average noise level at the homes located on the west side of Melrose Drive (Sites 1, 2 and 3 on Figure 3) would be approximately 60 to 64 dBA associated with traffic noise. This inciudes the noise attenuation associated with the existing five to six-foot high sound wall at the residences. The CNEL would be approximately one dBA 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, Melrose Drive would be aligned farther away from the homes near the intersection of Melrose Drive and Corintia Street. The future noise level at the homes located near the intersection would be approximately one dBA lower with the proj ect as compared to the not built 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 dBA. This noise level complies with the FHWA/Caltrans noise criteria. A child care facility is located at the business industrial park along La Costa Meadows Drive east of Rancho Santa Fe Road. The facility is partially shielded from traffic noise by intervening buildings. The future peak hour average noise level at this location would be approximately 62 dBA. This noise level would comply with the FHWA/Caltrans noise criteria. [& ASSOCIATES. INC. March 2001 12 Rancho Santa Fe Road Project • Acoustical Assessment Report 7.0 NOISE ABATEMENT MEASURES INCORPORATED INTO THE PROJECT Future noise levels would exceed FFIWA/Caltrans noise criteria at four homes located along Rancho Santa Fe Road. Preliminary mitigation measures for the affected homes have been evaluated to provide noise abatement and design information. With an eight-foot high sound wall located along western right-of-way, the future peak hour average noise level would be mitigated to 61 to 62 dBA. 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 Tahle 5. It should be noted that an eight-foot high sound wall is depicted in the engineering design plans as part of the City of San Marcos' Rancho Santa Fe Road widening project. The eight- foot wall 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 will construct an eight-foot high sound wall at these residences. If the City of Carisbad constructs the proposed project first, the City of Carisbad has committed to constructing the noted sound wall proposed by the City of San Marcos (City of Carisbad 1998).

These criteria involve analysis of economic and engineering considerations to determine if the barrier will be constructed with Federal funds. The "reasonable" portion of this analysis includes a cost per allowance per March 2001 13 MEADO\W&ti^OT Sound Wall O Receiver Location PROJECT GRADING SOURCE; ^okker^ngmMnng^ct^^ Scole in Feet Rancho Santa Fe Road Realignment - Acoustical Assessment Report Sound Wall Location FIGURE ii Rancho Santa Fe Road Project • Acoustical Assessment Report benefitted residence, and has been calculated based on the noise attenuation associated with an eight-foot high barrier. The calculation is provided in Attachment 3, and indicates that the cost is $33,000 per benefitted residence. The total reasonable allowance for abatement is $132,000. Utilizing a $14 per square foot construction cost for a noise barrier results in a total cost of approximately $53,760 for the noise barrier. The estimated cost of the noise barrier is less than the reasonable allowance per benefitted residence. Therefore, the cost of the noise barrier is considered reasonable. Caltrans/FFfWA determination of barrier feasibility will be constructed as part of the final project design process. Noise impacts associated with the proposed project would be less than significant at the existing residences located along Melrose Drive, therefore, mitigation measures are not proposed by the City at these residences. 8.0 CONSTRUCTION NOISE Noise generated by construction equipment on this project wouid occur with varying intensities and durations during the different phases of construction: clear and grub, earthwork, base preparation, paving and cleanup. Equipment expected to be used would include tractors, backhoes, pavers and other related equipment. Maximum noise levels at 50 feet range from approximately 75 to 95 dBA for the type of equipment normally used in a project such as this. Project construction will comply with applicable local requirements. Also, the contractor shall comply with ail local sound control and noise level standards, regulations and ordinances which apply to any work performed pursuant to the contract. Each internal combustion engine, used for any purpose on the job or related to the job, shall be equipped with a muffler of a type recommended by the manufacturer. No internal combustion engine shall be operated on the project without said muffler. l&MSOCIAireS, INC.
