An underground storm drain system was installed to collect and convey runoff for the rough graded condition. This pipe design is shown on City of Carlsbad Drawing No. 295-2. The hydrologic calculations for the storm drain system is contained in the study by P&D Technologies entitled "Hydrology Study for Carlsbad Tract No. 85-35, Aviara Units D & E." The study considered the site to be a future multi-family residential project with a storm drain system designed accordingly. Existing Conditions The City of Carlsbad constructions drawings referenced above have been As-Built approved and accepted. The site is rough graded on an approximate 6% grade in a northerly to southerly direction. Little to no vegetation exists on the graded soil. Surface drainage swales collect the^ storm runoff and concentrate it into the existing temporary desilting basins at the southerly end of the site. An underground 18" reinforced concrete pipe (RCP) collects the surface runoff, conveying it offsite to an existing 24" RCP. An ungraded natural Coastal Resource Area lies to the east of the site. The storm runoff from this area flows onto the site and is collected into an existing concrete ditch. The ditch directs the runoff into the existing underground storm drain system. Adjacent properties to the north, west, and south flow away form the site and do not appear to impact the hydrologic pattern of the site. Proposed Development The site is proposed as a multi-family residential project with private roads. The existing storm drain system will be realigned within the travelled way of the proposed private street traversing the site. The P&D Hydrology Study assumed a multi-family residential runoff coefficient, therefore, it is expected that a realigned 18" RCP storm drain will be sufficient for this project. The City of Carlsbad construction drawings show flow rates and velocities for the storm drain pipes. The final engineering hydrology study shall use the Rational Method to check the proposed street flows and pipe size of the realigned 18" RCP. The study shall be in conformance with the latest City of Carlsbad Master Drainage and the Carlsbad Drainage - Design Criteria handout. 94/160-R GORDON BRICKEN & ASSOCIATES CONSULTING ACOUSTICAL and ENERGY ENGINEERS April 18, 1994 REVISED ACOUSTICAL ANALYSIS SIX UNIT SUBDIVISION CITY OF CARLSBAD Prepared Gordon Bricken President /mmb Prepared for: MR.

A comprehensive list of recommendations and requirements is given in the following summary. Details are discussed in the body of the report. A. EXTERIOR NOISE CONTROL The project will not exceed 60 dBA CNEL as required by the City. B. INTERIOR NOISE CONTROL The buildings would be expected to be constructed, as a minimum, in accordance with the outline of Table 3. However, the following interior mitigation measures must be incorporated into the project to produce 45 dBA CNEL:,r (1) Add STC 25 glazing -- all Plan 1 Bedrooms 1 and 3; all Plan 2 Bedrooms 2/3 {2} Add STC 27 glazing -- Plan 2 Master Bedroom Note, that the only windows affected are those with a visual sight-line to the rail line. C. VENTILATION When calculations depend on having windows closed, as it is in this case, it is good practice to provide adequate fresh air ventilation without resorting to the opening of the windows, should the occupant desire not to do so. Air conditioning is recommended for all units. 1621 East Seventeenth Street, Suite K • Santa Ana, California 92701 • Phone (714) 835-0249 FAX (714)835-1957 94/160-R GORDON BRICKEN & ASSOCIATES CONSULTING ACOUSTICAL and ENERGY ENGINEERS 1.0 INTRODUCTION This report presents the results of a noise impact and design study of the proposed six unit subdivision project located between Date and Olive Avenues in the City of Carlsbad. Included in this report is a discussion of the expected exterior community noise environment and the recommendations for control of noise in the interior living areas. A vicinity map showing the general location of the construction site is presented on Exhibit 1 -- Site Location Map. The proposed development consists of six, single family detached dwellings. The east boundary of the site is 109 feet from the railroad tracks, which is the only potential major source of noise. Houses are interposed between the site and the tracks as well as a wall which extends along the backside of Olive. The site plan is shown on Exhibit 2. 2.0 APPLICABLE NOISE CRITERIA The City of Carlsbad requires all residential projects to conform to the requirements of Table 1. TABLE 1 APPLICABLE NOISE CRITERIA^ Exterior 60 dBA CNEL Interior 45 dBA CNEL (1) Please see NOISE RATING METHODS (Appendix 1) for a complete explanation of acoustical terminology. 1621 East Seventeenth Street, Suite K • Santa Ana, California 92701 • Phone (714) 835-0249 FAX (714) 835-1957 94/160-R 3.0 rMEASURED NOISE LEVELS i A measurement was conducted at the site on April 6, 1994. The chart is shown on Exhibit 3. The sound level is set by the freeway which is partially visible from the site. The average sound level was 52 dBA. A train passby registered a maximum 82 dBA with a Single Event Exposure Level of 86 dBA SENEL {This term forms a portion of the CNEL equation) . 4.0 DESIGN NOISE LEVELS 4.1 ROADWAY Interstate 5 is within 1,600 feet of the project site. Tamarack Avenue and Carlsbad Boulevard are the nearest surface streets of any consequence. Tamarack Avenue is approximately 1,100 feet from the site, while Carlsbad Boulevard is approximately 1,300 feet from the site. These roadways will not impact the site at these distances. Interstate 5 is approxi- mately 1,600 feet from the project site. This distance, along with building and terrain shielding between the freeway and the site, minimize the noise impact of Interstate 5 on the project site. Thus, roadway noise will not impact the project site. This line serves Santa Fe Railroad freight trains and Amtrak passenger trains at the present time. It is proposed as a route for the North County Transit District commuter rail service. 4.2 RAILROAD A line of the Santa Fe and Amtrak railroads passes to the east of the project site at a distance of 109 feet. The CNEL equation is of the form: CNEL = SENEL + 10 LOG W - 49.4 (Equation 1) where W = Nd + 3*Ne + 10*Nn Nd = Number of Trains 7 A.M. to 7 P.M. Ne = Number of Trains 7 P.M. to 10 P.M. Nn = Number of trains 10 P.M. to 7 A.M. The calculations, according to the HUD Methodology, were carried out to determine this rail line's impact on the site for freight and Amtrak operations. The HUD calculations produce a value called the Day-Night Noise Level {LDN) . This term is calculated the same way as the CNEL equation except the term, W = Nd + Ne + Nn) . The LDN and CNEL figures are almost always within 0.5 dBA. 94/160-R The HUD calculations are contained in Appendix 2. The NCTC levels were based on Equation 1 and field measure- ments of the Los Angeles Metrolink Commuter Trains were used. The results of these calculations yield a railroad noise level of 67 dBA LDN(CNEL) without accounting for the effect of the houses between the tracks and the site. The LDN and CNEL terms are essentially equal. The railroad parameters used for the railroad noise calculations are given in Table 2.

NCTD figures obtained from Mr. Peter Aaland, NCTD on 4/13/94. The existing houses sit on a bluff overlooking the railroad line. They are at the same approximate elevation as the project site. The bluff, the houses, shed, and the wall at the end of Olive form a barrier which will reduce the sound levels of the railroad. The barrier setup was simulated with a computer model. The calculations were carried out for four locations on the site located in the front and rear yards' of the two project lots nearest the tracks. The calculations are contained in Appendix 3. The results are 58.1 to 60.0 dBA CNEL based on the projected rail level. The results were derived another way as well. The sample train was measured at 86 dBA SENEL. Using the 94/160-R train operation figures given in Table 2, the resulting CNEL value at the measurement point would be 54 dBA CNEL. This is 3 to 6 dBA less than the calculation. Therefore, there is reasonable assurance that the calculated value is a worst case scenario. 4.3 AIRCRAFT There are no concentrated aircraft operations in the vicinity of the project site. Thus, aircraft noise will not impact the site. 5.0 MITIGATION MEASURES 5.1 EXTERIOR The exterior noise levels do not exceed 60 dBA CNEL. The site complies with the City requirements. 5.2 INTERIOR The City's exposure criteria for new resi- dential construction requires that the interior noise environment, attributable to outside sources; be limited to 45 CNEL. Analysis and recommendations for control of outdoor-to-indoor noise intrusion are presented in this section. ' The exterior-to-interior noise reduction expected for the planned construction was based on a detailed analysis of sample rooms and units planned for the development. Calculations of the expected typical noise reduction performance were performed for sample rooms. The analysis was based on the typical spectra expected for the primary sources of community noise impact, the typical octave-band transmission loss for each element in the planned building shell, the relative square footage of each element of the planned building shell, the expected typical interior surface treatment, and the acoustical absorption coefficient for each interior surface treatment. Corrections1 for the "A" Weighted room absorption factors are also included. Each component of the building shell (e.g. exterior wall, windows, doors, etc.) provides a different amount of transmission loss for each "A" Weighted octave- band of community noise. With the knowledge of the 94/160-R building shell components and their individual octave band transmission loss values for the noise sources, calculations of the composite building shell transmission loss can be made for each room. The characteristics of the basic building shell are given in Table 3.

This will require as m^ch as 15 dBA interior noise reduction at the first floor level (60- 45=15) and 22 dBA at the second floor level (67-45=22). Specific room calculations were carried out to determine whether additional mitigation is needed. The calculations are contained in Appendix 4, and the results are given in Table 4 on the following page. 94/160-R TABLE ROOM NOISE REDUCTION VALUES PLAN ROOM Living/Dining Kitchen/Nook Family Master Bedroom Bedroom 2 Bedroom 3 Living Room NOISE (dBA) REDUCTION 19* 21 21 23 24 25 26 25* 26 28* 21 23* 23 25 27 28* 21 23* 24 26 20* 21 22 23 25 26 CONSTRUCTION MINIMUMS Table 3 T-3 + STC 25 (1> glazing T-3 + STC 27 glazing T-3 + STC 27 glazing + Baffled Roof T-3 + STC 30 glazing + Baffled Roof T-3 + STC 33 glazing + Baffled Roof T-3 + STC 35 glazing + Baffled Roof Table 3 T-3 + STC 25 glazing Table 3 Table 3 T-3 + STC 25 glazing T-3 + STC 27 glazing T-3 + STC 27 glazing + Baffled Roof T-3 + STC 30 glazing + Baffled Roof Table 3 Table 3 T-3 + STC 25 glazing T-3 + STC 27 glazing T-3 + STC 27 glazing + Baffled Roof Table 3 T-3 + STC 25 glazing T-3 + STC 27 glazing T-3 + STC 30 glazing T-3 + STC 30 glazing + Baffled Roof T-3 + STC 33 glazing + Baffled Roof (2) (2) (2) Dining Room 30*Table 3 94/160-R TABLE 4 -- Continued ' ROOM NOISE REDUCTION VALUES PLAN ROOM Family Room Kitchen/Nook Bedroom 4 NOISE (dBA) REDUCTION 23* 25 27 25* 26 19 22* 24 26 / o \Master Bedroom^' Bedroom 2/3 19 21 22* 24 26 21 23* 23 25 27 CONSTRUCTION MINIMUMS Table 3 T-3 + STC 25 glazing T-3 + STC 27 glazing Table 3 T-3 + STC 25 glazing Table 3 T-3 + STC 25 glazing T-3 + STC 27 glazing T-3 + STC 30 glazing Table 3 T-3 + STC 25 glazing T-3 + STC 27 glazing T-3 + STC 30 glazing T-3 + STC 30 glazing + Baffled Roof Table 3 T-3 + STC 25 glazing T-3 + STC 27 glazing T-3 + STC 27 glazing + Bafflejd Roof T-3 + STC 3d glazing + Baffled Roof Satisfies requirement Please see Appendix 5 for an explanation of STC ratings.

Since community noise is seldom constant, varying from moment to moment and throughout the day, the "A" weighted noise level needs to be further described to provide meaningful data. The Environmental Protection Agency, Federal Department of Transportation, foreign countries and private consultants are now using three time-exceeded percentile figures to describe noise, which are: (1) Lqrt is the noise level which is exceeded 90% of any sample time period (such as 24 hours) and is used to describe the background or ambient noise level. (2) LCQ is the noise level which is exceeded 50% of the time. It is the median level. (3) LIO is the noise level which is exceeded 10% of the time and is a good descriptor of fluctuating noise sources, such as vehicular traffic. It indicates the near-maximum levels which occur from grouped single events. Being related to the subjective annoyance to community noise, it is a good design tool 1621 East Seventeenth Street, Suite K • Santa Ana, California 92701 • Phone(714) 835-0249 Page 2 of 3 in the planning of acoustical barriers. More recent noise assessment methods are based on the equivalent energy concept where L /vl represents the average energy content of a fluctuating noise source over a sample period The subscript (x) represents the period in which the energy is computed and measured. Current practice references the quantity to either one (1) hour, eight (8) hours, or twenty- four (24) hours. When referenced to one (1) hour, L is also sometimes called HNL (Hourly Noise Level) . Since L is the summation of the functional productseq * of noise level and duration, many combinations of noise level, duration time and time history can make up the same L value. Thus, an L /-.. equals 50 means only that the average noise level is 50 dB. During the 24-hour period there can be times when the noise level is higher than 50 dB, and times when it is lower. If the period of the measurement is only a single event, the energy content is not averaged. The energy expression for a single event is simply the sum of the functional product of the noise level and duration time of the event. This term is called L or SENEL (Single Event Noise Exposure Level)1. The summation of L values averaged over one hour is L ,1V,e y eq (1) ' Leq(8)' Snd Leq(24)' L is further refined into L, (Level Day-Night) and CNEL (Community Noise Equivalent Level) , where noises that occur during certain hours of the day are weighted (or penalized) because they are considered subjectively more annoying during these time periods: (1) Ldn is the sound level in dBA which corresponds to the average energy content of the noise being measured over a 24-hour period including a 10 dBA weighting penalty for sound levels which occur during the nighttime hours of 10:00 P.M. to 7:00 A.M. This is a rating method recommended by the Environmental Page 3 of 3 Protection Agency because it takes into account those subjectively more annoying noise events which occur during the sleeping hours. (2) CNEL. is the sound level in dBA which corres- ponds to the average energy content of the noise being measured over a 24-hour period including a five (5) dBA penalty for noise which occurs during the evening hours of 7:00 P.M. to 10:00 P.M., and a ten (10) dBA 'weighting penalty for noise that occurs during the night- time hours of 10:00 P.M. to 7:00 A.M. For typical high- way vehicular traffic situations, computer analysis has shown that CNEL and L, correlate within 0-5 dBA.an The percentile figures LIO/ Lso' and Lqn can be directly scaled from a graphical recording of the measured noise over a particular time period. They are also convenient to implement in automatic measurement equipment. Energy parameters Le' Lea' Ldn' an<^ CNEL require expensive and complicated equip- ment. As a result, engineers have devised ways of estimating L (and hence, L, ) using standard instrumentation and methods.

Not all similar products provide the same STC number. Attached are listings of ratings of the larger glazing manu- facturers. Every manufacturer listed does not have tests on every configuration. Absence of data, however, may simply be a reflection of an incomplete product file on our part. One may not transfer ratings for product types. Also, many of these products are special frame configurations, seal configurations, and glass configurations. Therefore, you must be certain to specify the correct frame and glass combinations.
