Method Detection Limit (MDL) - the minimum concentration of a subst ance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero
Matrix Spike (MS/MSD) - Client sample spiked with identical conc entrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix.

Matrix - the component or substrate that contains the analyte of interest (e.g., - groundwater, sediment, soil, waste water,e t c ) Laboratory Control Sample (LCS ad LCSD) - A known matrix spiked with compounds representative of the target analyte(s). This is used to document laboratory performance.

Duplicate - a field sample and/or laboratory QC sample prepared in duplicate following all of the same processes and procedures used on the original sample (sample duplicate, LCSD, MSD)
Blank (Method/Preparation Blank) -MB/PB - An analyte-free matrix to which all reagents are added in the same volumes/proportions as used in sample processing. The method blank is used to document contamination resulting from the analytical process.

Practical Quantitation Limit/Reporting Limit/Limit of Quantitation (PQL /RL/LOQ) - a laboratory determined value at 2 to 5 times above the MDL that can be reproduced in a manner that results in a 99% confidence level that the result is both accurate and precise. PQLs/RLs/LODs reflect all preparation factors and/or dilution factors that have been applied to the sample during the preparation and/or analytical processes.

Precision (%RPD) - The agreement among a set of replicate/duplicate measurements without regard to known value of the replicates Surrogate (S) or (Surr) - An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen method of analysis
Tentatively Identified Compound (TIC) -A compound not contained within the analytical calibration standards but present in the GCMS library of defined compounds. When the library is searched for an unknown compound, it c an frequently give a tentative identification to the compound based on retention time and primary and secondary ion match. TICs are reported as estimates and are candidates for further investigation.

Units: the unit of measure used to express the reported result - mg/L and mg/Kg (equivalent to PPM - parts per million in liquid and solid), ug/L and ug/Kg (equivalent to PPB - parts per billion in liquid and solid), ug/m3, mg/m3, ppbv and ppmv (all units of measure for reporting concentrations in air), % ( equivalent to 10000 ppm or 1,000,000 ppb), ug/Wipe ( concentration found on the surface of a single Wipe usually taken over a 100cm2 surface) B - Indicates when the analyte is found in the associated method or preparation blank D - Surrogate is not recoverable due to the necessary dilution of the sample E - Indicates the reportable value is outside of the calibration range of the instrument but within the linear range of the instrument (unless otherwise noted) Values reported with an E qualifier should be considered as estimated.

H- Indicates that the recommended holding time for the analyte or compound has been exceeded J- Indicates a value between the method MDL and PQL and that the reported concentration should be considered as estimated rather the quantitative NA - Not Analyzed
N/A - Not Applicable
ND - Not Detected at a concentration greater than the PQL/RL or, if reported to the MDL, at greater than the MDL.

NR - Not recoverable - a matrix spike concentration is not recoverable due to a concentration within the original sample that is greater than four times the spike concentration added
R- The % RPD between a duplicate set of samples is outside of the absolute values established by laboratory control charts S- Spike recovery is outside of established method and/or laboratory control limits. Further explanation of the use of this qualif ier should be included within a case narrative
X -Used to indicate that a value based on pattern identification is within the pattern range but not typical of the pattern found in standards.

Further explanation may or may not be provided w
ithin the sample footnote and/or the case narrative.

DEFINITIONS:

Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value.

ProUCL computes and outputs H-statistic based UCLs for historical reasons only.

H-statistic often results in unstable (both high and low) values of UCL95 as shown in examples in the Technical Guide.

It is therefore recommended to avoid the use of H-statistic based 95% UCLs.

Use of nonparametric methods are preferred to compute UCL95 for skewed data sets which do not follow a gamma distribution.

Note: Suggestions regarding the selection of a 95% UCL are provided to help the user to select the most appropriate 95% UCL.

Recommendations are based upon data size, data distribution, and skewness.

These recommendations are based upon the results of the simulation studies summarized in Singh, Maichle, and Lee (2006).

However, simulations results will not cover all Real World data sets; for additional insight the user may want to consult a statistician.

It is therefore recommended to avoid the use of H-statistic based 95% UCLs.

Use of nonparametric methods are preferred to compute UCL95 for skewed data sets which do not follow a gamma distribution.

Memorandum
Date: February 24, 2022
To: Jan Eiesland, MIG
From: Michelle Hunt and Rueben Rodriguez
Subject: Vehicle Miles Traveled, Multimodal Access, and Pedestrian Safety at Lawrence Mitty Park and Trail in Cupertino, California
Hexagon Transportation Consultants, Inc. has completed an initial assessment of Vehicle Miles Traveled (VMT), multimodal access, and pedestrian safety at Lawrence Mitty Park and Trail in Cupertino, California. The project site is located on the east side of Cupertino between the Lawrence Expressway and Saratoga Creek. A Master Plan is being developed for the site to plan for the recreation, trail, and open space needs of residents. The Plan will provide a park with recreation activities, facilities for outdoor play and exercise, educational opportunities, and open space. The Master Plan will also extend the existing Saratoga Creek walking and biking trail.

In accordance with Senate Bill (SB) 743 and the City’s Ordinance No. 21-2223, vehicle miles traveled (VMT) has replaced level of service (LOS) for use in transportation analyses pursuant to the California Environmental Quality Act (CEQA). This memorandum evaluates the project’s potential impact on vehicle miles traveled (VMT) and analyzes multimodal access and pedestrian safety. Although LOS is no longer the transportation analysis tool used in assessing the environmental impact of projects, the Cupertino General Plan contains LOS standards with which projects must comply. However, because this project would generate few additional vehicle trips, it is expected to have a negligible effect on intersection operations. Accordingly, City of Cupertino staff have determined that an analysis of intersection levels of service is unnecessary for this project.

Vehicle Miles Traveled
The City adopted a new VMT policy on March 2, 2021 based on the Senate Bill (SB) 743.

According to the City Ordinance, some projects may be screened out, or assumed to have a less- than-significant impact on VMT if they fall within the following categories:

1. Local serving retail of up to 50,000 square feet.

2. 100% affordable housing projects.

3. Projects located within 1/4 mile of Stevens Creek Blvd (from SR 85 east), measured in walking distance.

4. Small projects that generate less than 110 new trips per day, and do not exceed square footage thresholds.

The potential new daily vehicle trips that may be generated by the proposed project were estimated by applying trip rates for public parks published in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition (0.78 daily vehicle trips per acre) to the size of the project site (7.83 acres). Based on the ITE trip rate, the proposed project is expected to generate fewer than 10 Q ...., • ~DAGON l~ANSPO~TATION (ONSULTANTS. INC.

daily vehicle trips each day. This is considered a conservative (high) estimate of project-generated traffic because a portion of the site has limited improvement potential due to Saratoga Creek and other areas will provide for open space with only passive recreational uses rather than more intense, active park uses like sports fields. Furthermore, project vehicle trips are expected to be quite low because there is no direct public vehicle access to the project site (see discussion of multimodal access below).

Therefore, according to the Cupertino VMT policy, the project would qualify as a small project that may be screened out of a detailed VMT analysis and assumed to have a less than significant impact on VMT.

Furthermore, the Lawrence-Mitty site is located within the east side of Cupertino, which is underserved in terms of park space and recreational opportunities for residents. Thus, it is likely that many residents in this area of Cupertino area travel to parks, trails, and open spaces outside the area. For this reason, the project is expected to result in a reduction in the total (boundary) VMT.

Existing Multimodal Access and Pedestrian Safety
The Saratoga Creek Trail is a multi-use path that runs along the west side of Lawrence Expressway and extends from English Drive in the south to Mitty Way in the north. Currently, the trail ends at a gate approximately 40 feet north of the Lawrence Expressway and Mitty Way crosswalk.

The existing pedestrian and bicycle facilities are generally located south of the proposed project site. There are existing pedestrian facilities at the signalized intersections of Lawrence Expressway and Mitty Way and Lawrence Expressway and Moorpark Avenue/Bollinger Road. The intersection of Lawrence Expressway and Mitty Way includes a crosswalk along the south leg with push buttons, curb ramps with truncated domes, and pedestrian signal heads. The intersection of Lawrence Expressway and Moorpark Avenue/Bollinger Road includes crosswalks along each leg with push buttons, curb ramps with truncated domes, and pedestrian signal heads per the requirements set forth in the Americans with Disabilities Act (ADA). The existing pedestrian facilities at these two intersections provide access between the Saratoga Creek Trail and the sidewalks along the adjacent roadways. North of the project site, pedestrian facilities at the signalized intersection of Lawrence Expressway and Southbound I-280 On-Ramp/Calvert Drive are limited to a crosswalk on the east leg. A sidewalk extends south along the east side of Lawrence Expressway to Doyle Road, which provides an indirect connection via local neighborhood streets between the Lawrence/Southbound I-280/Calvert intersection and the Saratoga Creek Trail. While there are short segments of sidewalk along Lawrence Expressway at intersections near the project site, there ae no pedestrian facilities along the east and west sides of Lawrence Expressway that would enable residents to walk from intersection to intersection.

In the project vicinity, bicycles are permitted to ride on Lawrence Expressway. Bicycle detector pavement markings are provided on the roadway shoulders at the approaches to signalized intersections on Lawrence Expressway. Due to the high speed and volume of traffic on the expressway, bicyclists are advised to exercise caution.

The Sterling Barnhart Park is located at the southwest corner of the Lawrence Expressway and Mitty Way intersection. Pedestrian and bicycle access between the Saratoga Creek Trail and the adjacent Rancho Rinconada neighborhood is available through the park. The unsignalized intersection of Sterling Boulevard and Barnhart Avenue, located on the residential (west) side of the Sterling Barnhart Park and Saratoga Creek Trail includes a marked crosswalk on the north leg.

crosswalk includes curb ramps with truncated domes in conformance to the ADA. The crosswalk also has pedestrian crossing warning signs (signs W11-2 and W16-7P in the California MUTCD) and an overhead light to ensure visibility of pedestrians at night.

The project site has an existing driveway along Lawrence Expressway that is used by City maintenance vehicles. The existing driveway is located approximately 620 feet south of the Lawrence Expressway and Southbound I-280 On-Ramp/Calvert Drive intersection. The existing driveway provides sufficient storage for two vehicles to park side-by-side, without encroaching on the adjacent southbound shoulder area of Lawrence Expressway.

There is no on-site public parking and no direct vehicular access to the project site or Saratoga Creek Trail for the general public. To access the site by vehicle, visitors need to park on the adjacent residential streets near Sterling Barnhart Park and walk through the park to the multi-use path. Alternatively, park and trail visitors may park in the residential neighborhood east of Lawrence Expressway and then use the crosswalk on the south leg of the Lawrence/Mitty intersection.

Design Considerations and Recommendations
The project should connect to the existing pedestrian and bicycle facilities near the project site. The project site will serve as the northern most point of the Saratoga Creek Trail. The existing Saratoga Creek Trail ends near the southern edge of the site. It is recommended that the project tie-in to the existing trail to provide bicycle and pedestrian connectivity to the Lawrence Expressway and Mitty Way intersection and to Sterling Barnhart Park. The signalized crosswalk at the intersection of Lawrence Expressway and Mitty Way is adequate and there are no recommended changes to the existing pedestrian facilities at this intersection. Crosswalk visibility enhancements should be considered at the uncontrolled crosswalk at the intersection of Sterling Boulevard and Barnhart Avenue per the FHWA’s Guide for Improving Pedestrian Safety at Uncontrolled Crossing Locations.

Enhancements to improve crosswalk visibility may include high visibility crosswalk striping and parking restrictions on the crosswalk approaches so there is adequate sight distance for motorists on the approaches to the crossings and ample sight distance for pedestrians attempting to cross.

Alternatively, a bulb-out could be constructed to allow the pedestrian to see past the parked vehicle along the street.

There is no trail connection north of the project site. However, adjacent to the project site, bicycles are permitted on Lawrence Expressway. The project should consider providing inbound access for southbound Lawrence Expressway bikes near the north end of the project site. Note that the on-site design, signage, and pavement markings of this inbound bicycle access point should discourage and/or prevent wrong way bike use and pedestrian use. Multimodal improvements that would connect to the north end of the project, such as adding a Class II bike lane designation on southbound Lawrence Expressway and/or adding a crosswalk on the south leg of the Lawrence/Calvert/I-280 southbound on-ramp intersection that would connect to the Class I mixed- use trail on the east side of Lawrence Expressway should be considered.

The project site should continue to provide a city maintenance driveway adjacent to Lawrence Expressway. The driveway should be located at least 500 feet south of the Lawrence Expressway and Southbound I-280 On-Ramp/Calvert Drive intersection, which would be a sufficient distance to satisfy the California Department of Transportation (Caltrans) Highway Design Manual (HDM) stopping sight distance for a design speed of 55 miles per hour (mph). Note that Lawrence Expressway currently has a posted speed of 50 mph. The project driveway should provide sufficient space for a pick-up truck with a small trailer (i.e., a trailer that holds maintenance equipment such as a lawnmower) to park outside the gate without encroaching on the Lawrence Expressway VMT, Multimodal Access, and Pedestrian Safety at Lawrence Mitty Park/Trail February 24, 2022 P a g e | 4
roadway and should be designed per the County’s standards for driveways on County expressways. Furthermore, the site plan should allow vehicles to turn around within the driveway or within the project site to avoid the need for vehicles to back out onto Lawrence Expressway.
