Tentative Tract 73507
A. PURPOSE
The purpose of this study is quantify the 50-year storm event and design a preliminary storm drain system for the project that is capable of intercepting and conveying and protecting the project from a 50-year storm event.

B. PROJECT BACKGROUND
The Avanti-North project site consists of approximately 237 acres of vacant land. The adjacent land is vacant to the north, south and west. To the east are multiple single family residential (SFR) developments. It is bounded by Avenue K to the north, Avenue K-8 to the south, Tracts 61680 and 60450 to the East, and 70th Street West to the west. There is an existing Hydrology Study, titled ”Hydrology Study for Portion of Portal Ridge Watershed within Cities of Lancaster and Palmdale (Update of Cities’ Drainage Master Plans)”, prepared by CCL Engineering, Inc (CCL). Sections of this report pertinent to this project were used as the basis for this hydrology study.

The guidelines used for the tentative map stage of development may result in drainage facilities sized smaller than those based on detailed hydraulic criteria as described in Sections 2.7 and 3.7 of the Engineering Design Guidelines (EDG). Approval of a Tentative Map based on requirements of the City’s Subdivision Ordinance will in no way represent approval of the final drainage design. The final drainage facilities will be designed per guidelines in Sections 2.7 and 3.7.

II. DRAINAGE CONCEPT
The existing drainage pattern through the project site is a north-south sheet flow condition. There is a large offsite undeveloped drainage area immediately to the south, which is tributary to Tract 73507.

This offsite drainage area is south of the project site and north of Avenue L, known as Avanti-South.

The drainage area is approximately 246 acres of undeveloped land, which generates a total Q50 of 111 cfs. In the ultimate condition, developed flows from this site would have to be mitigated onsite and reduce the flows to undeveloped conditions prior to discharging downstream. There is tributary drainage areas from developments to the south of Avenue L that currently discharge onto AvantiSouth from two locations. One discharge point includes two existing storm drain outlets located on the north side of Avenue L and 65th Street intersection. The storm drains discharge a total of 435 cfs from a drainage area of 1,484.9 acres. The offsite developed flows discharge into an existing earthen channel which then transitions into sheet flow. The second discharge point is also located on the north side of Avenue L midway between 65th and 60th Streets. An existing storm drain outlet discharges 218 cfs from a drainage area of 1,162.8 acres. The offsite developed flows discharge into a concrete ditch that runs west for several hundred feet and transitions to an earthen ditch as it turns north. Values for developed discharge flows were obtained from a separate hydrology study prepared by CCL, as mentioned above and included in this report as reference documents.

An earthen berm is proposed along the southern right-of-way of Avenue K-8 to direct the offsite sheet flows to the low points. A storm drain inlet structure is proposed at two locations to intercept the undeveloped and developed offsite flows. The runoff from the east will flow into a 72” storm drain that runs north along 65th Street West K-8. The 72” storm drain increases to an 84” downstream of Basin 4. The runoff from the west will flow into a 66” storm drain that discharges directly into Basin 4.

Basin 4 primary outlet will discharge directly into Basin 3. All other Basins will have an individual

I:\80344\DRAINAGE\PRELIMINARY\Report\803-44 Prelim Hydro (TTM73507) Narrative .doc primary and secondary outlet discharging into 84” storm drain, which runs north along 65th Street West.

The Avanti-North development proposes multiple onsite storm drain facilities that will convey the 50- year storm event. The onsite runoff will be collected by curb and gutter and drain into catch basins.

The runoff is then conveyed by storm drain pipe and discharged into onsite proposed detention basins. The basins will individually attenuate the storm flows in order to mitigate for increase in runoff due to proposed development. Inlet stand risers are proposed at basins in order to restrict the flows prior to discharging into 84” storm drain. For a summary of bypass and mitigated flows refer to drainage exhibit and summary table included at the end of Section V. of this report.

There is an existing 72” storm drain (DWG. No. PMT 03-03954) along Avenue K that conveys flows from the SFR developments located east of the project site. A proposed 42” storm drain is proposed along Avenue K to convey offsite flows from the west. Both the proposed 42” and existing 72” storm drains will join with the proposed double 84” storm drain at Avenue K and 65th Street West intersection. In the ultimate condition, the trapezoidal channel will be removed and replaced with (2) 84” storm drain pipes. The proposed double 84” storm drain will run north and join to and existing 84” storm drain located on 65th Street West at Avenue J-12. Based on reference plans, the double 84” storm drain (DWG. No. PMT 04-00132) has a capacity of 750-800 cfs.

A. HYDROLOGY
The hydrology software program used for this study was HydroCalc 0.3.1-Beta. This program is based on the Modified Rational Method and is approved by the Los Angeles Department of Public Works (LADPW). These calculations compute design discharge rates within the delineated watershed boundaries. Discharges are computed based on the formula Q=CIA, where:

Q=Discharge in (cfs)
C=Runoff Coefficient based on Land Use
I=Rainfall Intensity (in./hr.)
A=Area (acres)
The runoff coefficient models the amount of flow that reaches storm drain facilities versus the portion of rainfall that infiltrates to the soil. The runoff coefficient is dependent on the amount of impervious cover and the rainfall intensity. The rainfall intensity is a measure of the rate of the rainfall and varies with the watershed time and concentration. The watershed time of concentration at any given point is defined as the time it would theoretically take runoff to travel from the most upstream point in the watershed to the subject location. Discharges have been computed for 50-year hypothetical storm return frequencies. The basic assumptions and criteria for use in runoff computations are:
 Soil Type: 134
 Initial area and flow path: varies
 Land Use: Based on impervious percentage (Natural, Single Family (SF) 7,200 -10,000 S.F.

Lots)
The rainfall intensity used for the 50-Year storm events is based on data obtained from LADPW 50-Yr. 24-Hr. Isohyet for Lancaster West, Figure 1-H1.67. The soil type number was also obtained by using the same Figure and 1-H1.66. Refer to Appendix E for Figures.

B. HYDRAULICS
The hydraulic study for the existing trapezoidal open channel was performed using the Water Surface Pressure Gradient (WSPG Version 2.40) program. It is a hydraulic analysis model that computes and plots uniform and non-uniform steady flow water surface profiles and pressure gradients in open channels or closed conduits with irregular or regular sections. The flow in a system may alternate between super critical, subcritical or pressure flow in any sequence. The program will also analyze natural river channels although the principle use of the program is intended for determining profiles in improved flood control systems. The WSPG program was originally developed by the Los Angeles County Flood Control District also known as program number F0515.

The pipe hydraulic calculations included in this report were performed by using the Manning’s equation in the AES HELE 1 software program. Additional information on pipe reaches is provided in Section V. Refer to existing channel and pipe hydraulic calculations included in Appendix F.

IV. HYDROLOGIC ANALYSIS
The hydrology study presented in this report includes the offsite undeveloped condition and onsite post-development condition for the 50-Year storm event. These calculations were also performed for use in unit hydrograph analysis. The analysis for this project consists of one analysis that will include

I:\80344\DRAINAGE\PRELIMINARY\Report\803-44 Prelim Hydro (TTM73507) Narrative .doc all tributary drainage areas to Tract 73507 including the offsite developed areas south of Avenue L.

The hydrology data for the tributary offsite watersheds south of Avenue L was obtained from Hydrology Study for Tract 53229, prepared by CCL Engineering, Inc. Refer to Appendix G for supporting documents.

A. OFFSITE UNDEVELOPED AND DEVELOPED CONDITION HYDROLOGY The offsite hydrology study consists of approximately 245.7 acres of undeveloped land immediately to the south of Avenue K-8. Moreover, an additional 2,647.7acres of developed areas south of Avenue L are accounted for in this study. The 50-Year discharge rates for the developed areas were obtained from a separate hydrology study prepared by CCL. In general, the site’s natural drainage pattern is a south-north sheet flow condition that is relatively flat with a grade of approximately 1.2%. The entire site consists of soil type 134. The total discharge at any given point was determined by simply adding the discharge rates. The total 50-Year discharge rates and drainage areas are labeled on the Offsite Hydrology Map-Sheet 1. Refer to Appendices A and F for calculations and hydrology Map, respectively.

B. ONSITE PRE-DEVELOPMENT HYDROLOGY
The onsite pre-development site consists of approximately 237.25 acres, of undeveloped natural land use, which includes detention basins. The entire site consists of soil type 134. The total 50-Year discharge rates and drainage areas are labeled on the Pre-developed Condition Hydrology Map Sheet

2. Refer to Appendices A and F for calculations and hydrology Map, respectively.

C. ONSITE POST-DEVELOPMENT HYDROLOGY
The onsite post-development site consists of approximately 237.25 acres, of residential land use, which includes parks sites and detention basins. The entire site consists of soil type 134. The total discharge at any given point was determined by simply adding the discharge rates. The total 50-Year discharge rates and drainage areas are labeled on the Developed Condition Hydrology Map-Sheet 2.

Refer to Appendices B and F for calculations and hydrology Map, respectively.

V. SUMMARY
Based on the offsite and onsite post-development condition hydrology and unit hydrograph analyses, we conclude that the proposed storm drain system will adequately intercept, convey and protect the project site up to the 50- year storm event.

I. INTRODUCTION
A. Purpose and Scope
The purpose of this study is to analyze the hydrology and hydraulic design for the proposed Avanti South residential development. This key points this study will address are:

1. The proposed building pads will sit above the revised FEMA Floodplain.

2. The proposed development will convey the on-site 25-year design storm via storm drain pipes while conveying the remainder of the 50-year design storm via street gutters. The 50-year design storms will be routed to on-site basins to either retain the design volume or detain 85% of the pre-development peak flow rate (Q).

3. The off-site drainage south of Avenue L shall be routed through the site via storm drain pipes.

B. Methodology and References
This study was performed using the following reference materials and tools:

1. Los Angeles County Department of Public Works Hydrology Manual. January 2006

2. HydroCalc (software)

3. Beltley FlowMaster (software)
C. Location and Description of Property
Figure 1 shows the proposed location of the proposed Avanti South residential development. The overall site includes a 240 acres portion bounded between Avenue L to Avenue K from 62nd Street West to 70th Street West and an 80 acre portion along 70th in Lancaster, CA. The APN’s for the project are 3204-001-195, 3204-001-184, 3204-008-045, 3204-008-047. The site is undeveloped and has some existing vegetation. This site is relatively flat sloping at approximately one percent (1%) from the south to north via sheet flow over the majority of the site. The off-site runoff is concentrated at 65th Street and the easterly boundary of the site. See Appendix C for a copy of the Assessor’s Parcels Map.

III. HYDROLOGY
A. Floodplain Information
Research into the Federal emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) for Los Angeles County, California and Incorporated Area Panel 415 of 2350 Map Number 06037C0415F Effective Date September 26, 2008 shows that the project lies within Zone X determined to be areas of 0.2% annual chance flood; areas of 1% chance flood with average depths of less than 1 foot or with drainage areas less than 1 square mile. (See FIRM attached Appendix C)
B. Overall Watershed Drainage
The project site lies within the Portal Ridge Watershed. This portion of the Portal Ridge Watershed was updated in 2005 via the Hydrology Study prepared for TTM 53229 by CCL Engineering. The noted study analyzed the off-site storm runoff that will affect the subject project as well as the onsite for TTM 53229. There exists (2) 72 inch storm drains in 65th Street West south of Avenue L that outlet to a graded ditch within an easement with a graded swale daylighting several hundred feet north of Avenue L. There are also (2) existing 84 inch storm drains in 65th Street West north of the subject property from Avenue J-12 northerly to Avenue J.

C. Drainage Concept
The noted 2005 hydrology study determined that 435 cfs is conveyed through the existing double 72 inch storm drains at 65th Street West that cross under Avenue L. It also determined that 218 cfs of offsite runoff enters the Avanti South site at the South East Corner (SEC) of the site, which is at Avenue L at the alignment of 62nd Street West. The Walmart project east of the Avanti South site is conditioned to install a storm drain in Avenue L to convey the 218 cfs to outlet at the SEC of the Avanti South site. The Avanti South project will convey the noted 435 cfs via a storm drain in 65th west from Avenue L northerly to Avenue K-8, the noted 218 cfs will be conveyed via a storm drain along the eastern portion of Avanti South to Avenue K-8, then westerly in Avenue K8 to 65th Street. The Avanti North project will then convey this offsite drainage through its site northerly to the existing 84 inch storm drain at Avenue J-12.

The 240 acre portion of Avanti South will mitigate the on-site storm run-off via four (4) detention basins located along the west side of 65th Street West. The on-site storm flows will be mitigated to 85% of the pre-developed condition out letting into the 65th Street West storm drains. The 80 acre portion of Avanti South will mitigate the storm run-off via three (3) retention basins.

Retention basins are proposed for this portion of the project since there are no proposed storm drains for outlet. The basins will rely on infiltration and the final sizing will be based upon the results of percolation tests.

KHA Project No. 099185002 Page 5 June 21, 2016
D. Project Site Drainage
Existing On-Site Drainage
The site is currently undeveloped natural grade and vegetation. Based on the Modified Rational Method (MODRAT) outlined in the LACDPW Hydrology Manual, using the HydroCalc software, the on-site 50-year pre-development peak runoff flow (Q) for the 240-acre parcel is 26.95 cfs.

Including the off-site flow, the total peak runoff flow is 679.95 cfs. For the 80-acre parcel the predevelopment peak runoff flow (Q) is 9.13 cfs. See Appendix B for HydroCalc data. The 240-acre parcel will utilize detention basins, which will be designed to mitigate the maximum outflow to 85% of the pre-developed peak runoff. The 80-acre parcel will utilize retention basins sized to capture 100% of the 50-year generated runoff volume. Therefore, no runoff will leave the site.

Developed On-Site Drainage
The developed site consists of backbone streets and mass-graded pads for future development.

Runoff will be conveyed to the basins via non-erosive drainage devices including catch basins and street gutters.

Based on the Modified Rational Method (MODRAT) outlined in the LACDPW Hydrology Manual, using the HydroCalc software, the 50-year post-developed runoff volume for the 240-acre and 80- area parcels are 2,224,101 cf and 700,832 cf respectively. See Appendix B for HydroCalc Data.

Since the developed runoff will be split into several sub-areas and captured in catch basins, the peak flows (Q) were analyzed for each drainage area (DMA). The hydrographs for the developed sub-areas were utilized to calculate the required storage of each basin.

IV. PROPOSED DRAINAGE FACILITIES
A. General Description
The project incorporates the following types of drainage facilities:

1. Concrete Street Gutters

2. Local Catch Basins

3. Retention Basins

4. Detention Basins
B. Hydraulic Analyses
According to the current Hydrology Report for the Avanti North property done by MDS Consulting, the 72” storm drain pipe proposed within 65th Street West will be daylighting into the detention basin located north of Avenue K-8. It is assumed that the hydraulic grade line at the basin will be at the invert of the outfall pipe. The 72” main will not be flowing under pressure. Therefore, the hydraulic grade lines of the system will be the same as the depth of flow. The flow depths are shown on the Basin Sections Exhibit in Appendix A.

Report
KHA Project No. 099185002 Page 6 June 21, 2016
C. Facility Design Calculations
Storm Drain Pipes
All storm drain pipes were sized using FlowMaster with Manning’s Formula. Peak flows were determined by establishing a baseline cfs/acre based on impervious data available in the LA County Hydrology Manual. This baseline cfs/acre was used to determine the total cfs flowing to each catch basin’s tributary area
Retention Basin
Retention basins for the 80-acre parcel are sized the hold the entirety of the 50-year storm. The retention rates of the existing soils are assumed to be 3.75 in/hr. This is based on percolation testing of a neighboring property conducted by Earth Systems. These assumed percolation rates will allow the 50-year storm to infiltrate within the required drawdown time. All calculations were performed using HydroCalc. Impervious values for specific plan areas were determined using Appendix D of the LA County Hydrology Manual based on proposed land use.

Detention Basin
Detention basins for the 240-acre parcel are sized to mitigate 85% of the peak pre-developed flow (Q) for each drainage area. Additional retention volume is provided below the detention floor based on the inverts of connecting storm drain pipes from the drainage areas. To be conservative, infiltration within the retention volume was not taken into account in the detention basin sizing. Detention volumes were determined by adding the volume of the proposed hydrograph that exceeded 85% of the peak runoff flow from the existing hydrograph.

All calculations were performed using HydroCalc. Impervious values for specific plan areas were determined using Appendix D of the LA County Hydrology Manual based on proposed land use.

V. CONCLUSIONS
Impact of proposed development on off-site property and facilities The proposed development results in a decrease in runoff and flow depth to the adjacent roadways adjacent to the site by limiting the flow leaving the site to 85% off the peak predeveloped flow for the 240-acre site. The 80-acre site shall capture and infiltrate 100% of the post-development 50-year design storm. The proposed grading design maintains the historic drainage patterns and adequately conveys all off-site drainage through the site via a proposed storm drain system.

On-site flood protection
The proposed project shall set pads above existing grade ensuring the site will remain outside of the FEMA floodplain.

CITY OF LANCASTER
Appendix E - Noise Assessment
14033‐03 Noise Assessment.docx
August 16, 2022
Mr. Mike White
City Venture
3121 Michelson Drive, Suite 150
Irvine, CA 92612
SUBJECT: AVANTINORTH SPECIFIC PLAN NOISE ASSESSMENT
Dear Mr. Mike White:

Urban Crossroads, Inc. is pleased to provide the following Noise Assessment for the Avanti North Specific Plan development (referred to as “Project”) located on the southeast corner of 70th Street West and W.

Avenue K in the City of Lancaster. The purpose of this Noise Assessment is to evaluate the changes in the Project,specifically as compared to the Avanti North Residential TTM No. 73507, to determine if any additional impacts would occur as compared the Avanti North Specific Plan TTM No. 73507 Noise Impact Analysis (1) (2016 Noise Analysis) prepared for the original Avanti North Specific Plan.

At the time the 2016 analysis was prepared, the original Avanti North Specific Plan was proposed to include up to 758 family detached residential dwelling units and 10.30 acres of park space, referred to hereafter as the “Prior Project”.

The revised Avanti North Specific Plan includes the development of 878 single family detached residential dwelling units and 13.30 acres of park space, to be developed within a single phase, referred to hereafter as the “Currently Proposed Project”. As such, the Currently Proposed Project would result in a net increase of 120 single family detached residential dwelling units and 3.0 acres of park space.

ISSUES NOT REQUIRING DETAILED REEVALUATION
The Currently Proposed Project would result in higher densities within the same Project site as the 2016 study area. The approximately 15 percent increase in residential density would not substantially increase operational noise levels from the Project. As with the Prior Project, the Currently Proposed Project is not expected to include any specific type of operational noise sources beyond the typical noise sources associated with similar residential land uses in the Project study area, such as people and children, garage doors, small air conditioners, and trash collection. Additionally, residential land uses are typically considered noise‐sensitive receiving land uses and not noise generating land uses, such as industrial and large commercial and recreational land uses.

No noise impacts associated with aircraft noise were identified in the 2016 Noise Analysis and no new impacts would be created by the Currently Proposed Project.

The change in land uses would not substantially alter the anticipated construction noise or vibration levels since the distance between construction and the receivers (distance from the edge of the Project boundary)

would not change and there would not be a substantial change in the necessary equipment. However, since construction activities would be similar, the following construction noise abatement measures identified in the 2016 Noise Analysis would continue to be required for the Currently Proposed Project:
 Prior to approval of grading plans and/or issuance of building permits, plans shall include a note indicating that noise‐generating Project construction activities shall only occur between the hours of 7:00 a.m. to 8:00 p.m. on any day with no activity allowed on Sundays. The Project construction supervisorshall ensure compliance with the note and the City shall conduct periodic inspection at its discretion.  During all Project site construction, the construction contractors shall equip all construction equipment, fixed or mobile, with properly operating and maintained mufflers, consistent with manufacturers’ standards. The construction contractor shall place all stationary construction equipment so that emitted noise is directed away from the noise sensitive receivers nearest the Project site.  The construction contractor shall locate equipment staging in areas that will create a minimum distance of 100 feet between construction‐related noise sources and noise‐sensitive receivers nearest the Project site (i.e., the center of the site) during all Project construction.  The construction contractor shall limit haul truck deliveries to the same hours specified for construction equipment (between the hours of 7:00 a.m. to 8:00 p.m. on any day with no activity allowed on Sundays).

The haul route exhibit shall design delivery routes to minimize the exposure of sensitive land uses or residential dwellings to delivery truck‐related noise.

As in the 2016 Noise Analysis, with the incorporation of these measures impacts would remain less than significant.

The on‐site traffic noise analysis in the 2016 Noise Analysis conservatively uses future maximum traffic noise level volumes for adjacent roadways, thus the identified noise barriers and interior mitigation would be similar for any unit fronting Avenue K, 70th Street West, 65th Street West, and Avenue K-8.

Thus, the Currently Proposed Project would still be required to construct 6-foot-high noise barriers for the outdoor living areas(backyards) of the lots adjacent to Avenue K, 70th Street West, 65th Street West, and Avenue K-8. As in the 2016 Noise Analysis, with the incorporation of this noise barrier on‐site traffic noise impacts would remain less than significant.

ISSUES REQUIRING DETIALED REEVALUATION
The greatest potential for new noise impacts resulting from the Currently Proposed Project are related to off‐site traffic noise impacts associated with the redistribution of traffic and changes in off‐site traffic volumes on surrounding off‐site roadway segments.

OFF‐SITE TRAFFICNOISE ANALYSIS
Traffic generated by the Project will influence the traffic noise levels in surrounding off‐site areas. To quantify the off‐site traffic noise increases on the surrounding off‐site areas, the 2016 Noise Analysis Mr. Mike White

evaluated changes in traffic noise levels on roadway segments surrounding the Project site based on the change in the average daily traffic (ADT) volumes. The traffic noise levels provided in the 2016 Noise Analysis are based on the traffic forecasts found in the Avanti North Specific Plan Traffic Impact Analysis prepared by Urban Crossroads, Inc. in July 2016. (2) The 2016 off‐site traffic noise analysisindicated that the Project’s contributions to roadway noise level increases at adjacent sensitive land uses will be less than significant under existing and future conditions.

To quantify the off‐site traffic noise increases on the surrounding off‐site areas, this analysis also evaluates changes in traffic noise levels on roadway segments surrounding the Project site based on the change in the average daily traffic (ADT) volumes. The traffic noise levels provided in this noise analysis of the currently Proposed Project are based on the traffic forecasts found in the Avanti North Specific Plan Focused Traffic Assessment prepared by Urban Crossroads, Inc. in August 2022. (3) Noise contours presented in Tables 1 through 4 represent the distance to noise levels of a constant value and are measured from the center of the roadway for the 70, 65, and 60 dBA noise levels. The noise contours do not take into account the effect of any existing noise barriers or topography that may affect ambient noise levels. In addition, since the noise contoursreflect modeling of vehicular noise along area roadways, they appropriately do not reflect noise contribution from the surrounding commercial uses within the Project study area. Tables 1 to 4 present a summary of the unmitigated exterior traffic noise levels for the 38 study area roadway segments analyzed from the without Project to the with Project conditionsin each of the timeframes: Existing and Year 2020 conditions. Appendix 1 includes a summary of the traffic noise level contours for each of the four traffic scenarios.

EXISTING CONDITION PROJECT TRAFFICNOISE LEVELS
Table 5 presents a comparison of the Existing without and with Project conditions CNEL noise levels.

Table 1 showsthat the exterior noise levels are expected to range from 56.4 to 72.6 dBA CNEL for Existing without Project conditions. Table 2 presents the Existing with Project conditions noise level contours that are expected to range from 56.4 to 72.7 dBA CNEL. As shown on Table 5 the Project is expected to generate an exterior noise level increase of up to 2.8 dBA CNEL. Based on the significance criteria in Section 4 of the 2016 Noise Analysis, no segments will experience a significant unmitigated exterior noise level impact due to the Project’s contribution to off‐site traffic volumes under Existing conditions.

Therefore, off‐site traffic noise impacts under the currently Proposed Project would be less than significant.

14033‐03 Noise Assessment.docx
YEAR 2020 PROJECT TRAFFICNOISE LEVEL CONTRIBUTIONS
Table 6 presents a comparison of the Year 2020 without and with Project conditions CNEL noise levels.

Table 3 shows that the exterior noise levels are expected to range from 62.8 to 73.4 dBA CNEL for Year 2020 without Project conditions. Table 4 presents the Year 2020 with Project conditions noise level contours that are expected to range from 62.8 to 73.4 dBA CNEL. As shown on Table 6 the Project is expected to generate an exterior noise level increase of up to 1.3 dBA CNEL. Based on the significance criteria in Section 4 of the 2016 Noise Analysis, no segments will experience a significant unmitigated exterior noise level impact due to the Project’s contribution to off‐site traffic volumes under Year 2020 conditions. Therefore, off‐site traffic noise impacts under the currently Proposed Project would be less than significant.

The off‐site traffic noise analysis presented in Tables 5 and 6 indicate that the Project’s contributions to roadway noise levels at adjacentsensitive land uses will be lessthan significant under existing and future conditions and would be consistent with the findings in the 2016 Noise Analysis.

CONCLUSIONS
This Focused Noise Assessment evaluates the proposed the changes in the Project, specifically as compared to the Avanti North Residential TTM No. 73507, to determine if a net increase of 120 single family detached residential dwelling units and 3.0 acres of park space will result additional impacts as compared the 2016 Noise Analysis for the original Avanti North Specific Plan. The proposed changes would not substantially increase operational noise levels or result in impacts relative to aircraft noise.

The on‐site noise compatibility impacts would be the same and would require similar mitigation measures as identified in the 2016 Noise Analysis. The changes in the land use density and park size would not substantially change the construction noise or vibration analyses as all equipment would be at similar distances to off‐site receivers as assessed in the 2016 Noise Analysis. Based on the changes in traffic distribution resulting from the proposed changes as evaluated in the Avanti North Specific Plan Focused Traffic Assessment (1), noise level increases along all roadway segmentssurrounding the Project site would be less than significant and no new noise impacts would occur due to the Currently Proposed Project. If you have any questions, please contact me directly at (619) 778‐1971.

AVANTI NORTH SPECIFIC PLAN FOCUSED TRAFFIC ASSESSMENT
Mr. Mike White,
This letter has been prepared to document the findings for the focused traffic assessment for the proposed Avanti North Specific Plan (Project) located on the southeast corner of 70th Street West and W. Avenue K in the City of Lancaster. Specifically, this traffic assessment has been prepared to determine if the development of the proposed Project will increase the anticipated traffic deficiencies compared to the Avanti North Residential TTM No. 73507, September 26, 2016, prepared by Urban Crossroads, Inc., referred to hereafter as the “2016 Traffic Study.”

PROJECT OVERVIEW
The proposed Project includes the development of 878 single family detached residential dwelling units and 12.9 acres of park space, to be developed within a single phase. A preliminary site map is shown on Exhibit 1.

STUDY AREA
The study area utilized for this analysis is consistent with the 2016 Traffic Study.

TRIP GENERATION
In order to develop the traffic characteristics of the proposed Project, trip-generation statistics published in the Institute of Transportation Engineers (ITE) Trip Generation Manual (11th Edition, 2021) was used to estimate the trip generation. For purposes of this analysis, the following land use codes and vehicle mixes have been utilized:
• Single Family Detached Housing (ITE Land Use Code 210) • Public Park (ITE Land Use Code 411)
The proposed project trip generation rates are summarized in Table 1. The trip generation for the proposed Project is summarized in Table 1, which shows the Project is anticipated to generate 8,290 two-way trip-ends per day with 615 AM peak hour trips and 827 PM peak hour trips.
