coordination with state and federal agencies. Furthermore, the City’s Specific Planning process has already resulted in the creation of connected open space corridors throughout the Planning Area which contain much of the sensitive habitat in the Planning Area.

Impacts related to conflicts with local ordinances protecting biological resources were found to be less than significant (GP EIR page 4.8-79) because while buildout of the Planning Area would result in impacts to biological resources, all development would be subject to and consistent with the city’s ordinances and policies such as the Tree Preservation Ordinance. Therefore, impacts related to conflict with local ordinances were found to be less than significant.

Impacts related to conflict with the provisions of an adopted Habitat Conservation Plan, Natural Conservation Community Plan, or other approved Conservation Plan were found to be less than significant because there are no adopted plans which apply to the Planning Area.

All of the analyses described above are based on the potential impacts of grading and general development within the Planning Area, and the HE Addendum noted that the Housing Element neither changed the boundaries of the Planning Area nor the locations of potential grading and development within the Planning Area. Therefore, the GP EIR and Addendum analyses of biological resources adequately and appropriately describe the potential impacts of the Project. The Project area is within a developed and urbanized location of the Planning Area, where significant impacts to biological resources would not be expected to occur. Further, as described in the environmental setting, the site has been previously disturbed and graded pursuant to previously approved development entitlements, and federal permits for loss of wetlands were effectuated. No sensitive biological resources remain on the site.

The previously evaluated project in the MND included a request for a Section 404 Individual Permit from the US Army Corps of Engineers and a Section 401 of the Clean Water Act permit certified by the Central Valley Regional Water Quality Control Board to allow the fill of various wetlands and waters on the site. The wetland features onsite consisted of several scattered ephemerally wet features and an unnamed tributary to Pleasant Grove Creek, flowing from south to north through the far western portion of the site. The wetlands delineation identified a total of 1.95 acres of potentially jurisdictional waters including 1.695 acres of wetlands and 0.258 acres of other waters. The wetlands consist of 0.554 acres of vernal pools, 0.859 acres of seasonal wetlands, 0.143 acres of seasonal wetland swale, and 0.139 acres of seasonal marsh. Other waters include 0.248 acres of intermittent drainage and 0.010 acres of a drainage ditch. The MND required mitigation measure BIO#1 to ensure appropriate permits were obtained from the US Army Corps and a Clean Water Act Section 401 permit. Compliance with the mitigation measure would ensure the proposed discharge complies with all State water quality requirements. Further, the MND required mitigation measure BIO#2 to ensure the project complied with the City’s best management practices for water quality control and Storm Water Pollution Prevention Plan (SWPP). Both of these mitigation measures were satisfied prior to the start of any grading activities for the site. At this time, the entire sites have been mass graded. All required permits for site development related to biological resources have been obtained and effectuated.

The previous MND surveyed the project site for the presence of eight special-status plant species (i.e., these include Sanford’s arrowhead, bigscale balsamroot, Boggs Lake hedge-hyssop, Ahart’s dwarf rush, Greene’s legenere, dwarf downingia, slender Orcutt grass). The survey results found that no occurrences of the aforementioned species where found on the property. Furthermore, the applicant retained a biologist with Adema Environmental who produced a Biological analysis (Attachment 3), which found no new or significantly increased impacts to biological resources on the site which would occur with the construction of the Project. Therefore, revised or new mitigation is not required; the adopted MND mitigation listed below remains applicable to the Project.

The previous MND found the site contained potential habitat for several special-status invertebrates, amphibians, and bird species listed by the California Department of Fish and Game. Although none of the special status wildlife species were observed onsite, the loss of vegetation could destroy unobserved nesting habitat for birds. Mitigation Measure BIO#3 requested that pre-construction surveys be completed to confirm the absence of special status wildlife. As previously mentioned, the project site has been previously mass graded and disturbance of the site has occurred. The Project will not result in any new or modified impacts to biological resources. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR have occurred.”
Mitigation Measures: Applicable mitigation measures from the MND are below; no new measures are warranted for this Project.

MITIGATION MEASURE BIO#2: Prior to grading and excavation activities on-site, the developer shall obtain a grading permit to ensure that the project is in compliance with City’s best management practices for water quality control and the Storm Water Pollution Prevention Plan (SWPPP).

MITIGATION MEASURE BIO#3: A qualified biologist shall perform pre-construction surveys for nesting birds and raptors at least 30 days in advance of construction if construction is planned during January to July. If the survey does not identify any special-status birds or raptors species, no further mitigation is required. If nesting is found to be occurring, avoid disturbance of the nest site with a suitable buffer zone. The on-site biologist shall consult with the California Department of Fish & Game to determine the size of the no-

A cultural resources survey report prepared by ECORP, dated August 2009 was completed with the MND. The report concluded that no cultural resources are known to exist on the project site.

Standard mitigation measures in the General Plan EIR will be applied to reduce impacts to cultural resources, should any be found on-site. The mitigation measure requires that in the event of a discovery of buried archeological or historic deposits, project activity in the vicinity to be halted until a qualified archeologist can assess the resources and provide management. This mitigation need not be applied herein, as it is already applicable and required of the Project pursuant to the General Plan EIR. The Project will not result in any new impacts beyond those already discussed and disclosed in the WRSP EIR and MND; therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.” Mitigation Measures: None required for this Project.

However, based on the existing Industrial land use designation the project was therefore assumed for development with industrial uses in the citywide environmental analyses, such as in the Amoruso Ranch Specific Plan, which updated the City’s General Plan. The project is therefore consistent with the current citywide assessment of energy demand, and it is determined it would not result in substantial unplanned demands, nor would it result in inefficient, wasteful, or unnecessary consumption of energy; therefore, impacts were found to be less than significant. Pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.” Mitigation Measures: None required for this Project.

Same No No No None
Discussion: The MND did not address climate change or greenhouse gas emissions because the MND determined there were no thresholds of significance against which to measure the impacts of the project and as a result the project was evaluated qualitatively relative to its incremental contribution to the overall issue of global warming. While the MND did not evaluate impacts related to greenhouse gas (GHG) emissions, the potential environmental impact of GHG emissions was known or could have been known with reasonable diligence at the time of the adoption of the MND, but no one raised the issue to the City. According to case law, a supplemental or subsequent EIR therefore may not be required here simply because the City is considering changes to a project that was approved based on an MND before CEQA expressly required GHG analysis.

(See Citizens Against Airport Pollution v. City of San Jose (2014) 227 Cal.App.4th 788, 806-808 [upholds addendum for changes to an approved airport master plan even though the underlying 1997 EIR and 2003 Supplemental EIR did not address GHG impacts]; see also Citizens for Responsible Equitable Environmental Development (CREED) v. City of San Diego (2011) 196 Cal.App.4th 515, 530-532; and Concerned Dublin Citizens v. City of Dublin (2013) 214 Cal.App.4th 1301, 1318-1320.). It is acknowledged that the project would include sources of greenhouse gas emissions; however, the project also includes mitigating features that are beneficial in terms of minimizing greenhouse gas emissions. Based on these reasons, this Project would not make a significantly greater contribution to GHG emissions than what was previously evaluated. Thus, based on a body of case law, the MND’s lack of GHG analysis does by itself not preclude adoption of an addendum for the proposed project and pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR have occurred” relative to GHGs.

Mitigation Measures: None required for this Project.

Same No No No
g) Expose people or structures either directly or
indirectly to a significant risk of loss, injury or
death involving wildland fires?
Same No No No
Discussion: The MND found that the previously evaluated project has a Light Industrial zoning and the potential for future users to have hazardous materials on-site could occur. However, it is unknown at this time if any hazardous materials will be used or stored on-site. The California Health and Safety Code and local City Ordinances regulate the handling, storage, and transportation of hazardous and toxic materials.

The California Health and Safety Codes require a Risk Management and Prevention Program (RMPP) for those uses that handle specified quantities of toxic and/or hazardous materials. Also, businesses that handle toxic or hazardous materials are required to complete a Hazardous Materials Management Program (HMMP). Furthermore, all business owners must file a site-specific business plan with the City Fire Department before a new building is occupied. All plans would need to specify what materials would be used or stored on-site and what to do in the event of an accident and which transportation routes would be used. With the implementation of the HMMP and business plan requirements, the use of storage of hazardous materials on-site would be reduced to less than significant levels with the appropriate aforementioned implementation HMMP and business plan requirements.

The MND found that during construction activities there is the possibility that potentially hazardous materials might be stored or used at the project site. The developer (during construction) is required to comply with all California Health and Safety Codes and local City Ordinances regulating the handling, storage and transportation of hazardous and toxic materials. The California Health and Safety Codes require a Risk Management and Prevention Program (RMPP) for those uses that handle specified quantities of toxic and/or hazardous materials.

The project site is not located within an airport land use plan area, no airports are located within two miles of the project site, and the project site is not located within the vicinity of a private airstrip. The project site is within an area of the City currently receiving emergency services and the project would not increase the demand for emergency services beyond that identified in the General Plan EIR.

The proposed project use does not significantly change the project’s potential impacts related to hazardous materials, and it will also be subject to the City’s existing regulations and permits that would prevent significant impacts. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.”

The proposed project has been evaluated by the City to ensure the design continues to meet current adopted stormwater quality design standards. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred” as it relates to hydrology and water quality impacts Mitigation Measures: None required for this Project.

XI. Land Use and Planning
Where Impact
Was Analyzed
in Prior
Environmental
Documents.

The MND found that the previously evaluated project was consistent with the policies of the Zoning Ordinance and General Plan, which are adopted for the purpose of avoiding environmental effects. These conclusions remain applicable to the proposed project. The proposed industrial buildings are consistent with the zoning and land use designations of the site. City staff has determined that the project is consistent with the standards and guidelines outlined in the City’s Zoning Ordinance, Community Design Guidelines, and the North Roseville Area Design Guidelines, including setbacks, landscaping, lighting, and building architecture to fit in with the surrounding community. The project will not divide an existing community and no conflicts with policies adopted for the purpose of avoiding or mitigating an environmental effect have been identified.

The Project is substantially consistent with the build out assumptions and would not increase the severity of already identified significant impacts; therefore, there would be no new significant impacts not previously identified in the MND relative to land use. Thus, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred” relative to land use and planning Mitigation Measures: None required for this Project.

Discussion: The MND addressed construction noise, and found that surrounding uses may experience short-term increases in noise levels.

However, these increases would only occur for a short period of time. When conducted during daytime hours, construction activities are exempt from Noise Ordinance standards, but the standards do apply to construction occurring during nighttime hours. While the noise generated may be a minor nuisance, the City Noise Regulation standards are designed to ensure that impacts are not unduly intrusive. Based on this, the MND found that impacts would be less than significant. This conclusion remains appropriate and applicable to the Project.

The MND found the buildout in the area would result in an increase in the ambient (background) noise level in the project area. In particular, point source noise form vehicular traffic is anticipated to raise the ambient noise level in the area. However, the MND found that the anticipated level of traffic is within the limits anticipated by the General Plan EIR and CIP EIR for build out of the project site. The future users on-site will be required to maintain noise levels in accordance with the City’s Noise Ordinance. Based on this, the MND found that impacts would be less than significant. This conclusion remains appropriate and applicable to the Project.

Discussion: The MND indicates that the City’s General Plan examined Citywide service needs based on land use designations, so any project consistent with existing land use designations would not negatively impact services. The proposed project remains consistent with the land use designation of the site, and therefore this conclusion remains appropriate for this Project. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.”

Discussion: The MND indicates that the City’s General Plan examined the level of park services that would need to be provided in order to serve planned growth in the community. This was based on land use designations, so any project consistent with existing land use designations would not cause any unforeseen or new impacts related to the use of existing or proposed parks and recreational facilities, or related to the construction or expansion of recreational facilities. The proposed project remains consistent with the land use designation of the site, and therefore this conclusion remains appropriate for this Project. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.”

Discussion: The MND determined the previously evaluated project would result in less than significant impact on traffic and transportation.

The project site was anticipated for development and transportation/traffic impacts were analyzed in General Plan EIR and 2020 CIP EIR. The 2020 CIP EIR was prepared for the Transportation System Capital Improvements Program Update that reflected changing conditions and ensured an adequate transportation system was in place.

A long-term traffic analysis has been prepared for the project by DKS Associates (dated July 27, 2007) and analyzed the project’s potential level of service impacts at the City’s existing intersections. The results of the study did not identify any significant impacts to the City’s CIP intersections. The traffic analysis was reviewed by the City’s Public Works Department, Engineering Division, and found to be adequate to support the findings.

Further, a short-term traffic analysis was prepared for the project by Fehr & Peers Transportation Associates (dated August 5, 2008). The short-term analysis looked at transportation impacts as a result of the trip generation created by the project and evaluated turning movements and site and circulation improvements. The analysis also evaluated the improvements to the City’s existing roadways and circulation system that are proposed as part of the project as well as the City proposed improvements adjacent to the project site. The analysis was reviewed by the City’s Public Works Department, Engineering Division, taking into account the City of Roseville level of service policies and improvement standards. The analysis determined, and the Engineering Division concurred, that the existing traffic levels of service do not meet City level of service standards and, the proposed project plus development of the adjacent Parcel 49 project, would exasperate traffic conditions.

However, with the proposed improvements, the project would restore traffic operations to better than “no project” levels. The project drive aisle depths and internal circulation were also found to be adequate for the project and do not present a known traffic hazard.

The MND also analyzed the left-hand turn lane at the intersection of the HWY 65 fly-over and the jughandle and found that it presented a vehicular safety issue. The previously approved roadway improvements proposed with the project would improve vehicular safety and circulation in the area would improve with the project and emergency access will not be negatively impacted. However, a Focused Access Evaluation of the project was prepared by Fehr & Peers Transportation Associates (dated July 27, 2022) (Attachment 2) found that the second driveway along Industrial Avenue would permit all turning movements. The same study also found that the driveway closest to the HWY 64 fly-over would only permit inbound and outbound movements to right-turns only.

Given the foregoing changes introduced by the Project, these changes would not as compared to the MND result in a new significant impact or significant impacts that are substantially more severe than significant impacts previously disclosed. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred” as it relates to transportation impacts.

Mitigation Measures: None required for this Project.

Discussion: In addition to archeological resources, tribal cultural resources are also given particular treatment. Tribal cultural resources are defined in Public Resources Code Section 21074, as either 1) a site, feature, place, geographically-defined cultural landscape, sacred place, or object with cultural value to a California Native American Tribe, that is listed or eligible for listing on the California Register or Historical Resources, or on a local register of historical resources or as 2) a resource determined by the lead agency, supported by substantial evidence, to be significant according to the historical register criteria in Public Resources Code section 5024.1(c), and considering the significance of the resource to a California Native American Tribe. The MND had a cultural resources survey report completed by ECORP, dated August 2009. The report concluded that no cultural resources are known to exist on the project site. While it is anticipated that there will be no impacts to cultural resources, the project will be conditioned to adhere to the General Plan EIR mitigation measures that require, in the event of a discovery of buried archeological or historic deposits, project activity in the vicinity to be halted until a qualified archeologist can asses the resources and provide management. Consistent with the MND, impacts to potential cultural resources are therefore considered to be less than significant and pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.” Mitigation Measures: None required for this Project.

Discussion: The MND found that the previous project would have a less than significant impact on utilities and services. The proposed project has been analyzed by City and external service and utility providers, and has been found to be consistent with standards, and utilities and service demands are within the scope of the previously analyzed project. Furthermore, Citywide planning of water supply and sewer infrastructure is based on land use, and the Project is consistent with the existing land use designation. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.” Mitigation Measures: None required for this Project.

Same No No No Same
Discussion: The MND did not previously analyzed the wildfire effects of the project. However, the checklist questions a—d above do not apply, because the project site is not within a Very High Fire Hazard Severity Zone and is not in a CAL FIRE responsibility area. The project receives fire protection from the Roseville Fire Department. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.”
Mitigation Measures: None required for this Project.

b) Does the project have impacts which are
individually limited, but cumulatively
considerable? (“Cumulatively considerable”
means that the incremental effects of a project
are considerable when viewed in connection with
the effects of past projects, the effects of other
current projects, and the effects of probable
future projects.)
Same No No No None
c) Does the project have environmental effects
which will cause substantial adverse effects on
human beings, either directly or indirectly?
Same No No No None
Discussion: The MND concluded that long term environmental goals are not impacted by the proposed project and the cumulative impacts do not deviate beyond what was contemplated by the 2020 General Plan EIR. With implementation of the proposed mitigation measures the project does not have the potential to degrade the quality of the environment, substantially reduce the habitat of any wildlife species nor create adverse effects on human beings. Based on the foregoing, the proposed project does not have the potential to degrade the quality of the environment, substantially reduce the habitat of any wildlife species, or create adverse effects on human beings. Therefore, pursuant to CEQA Guidelines section 15164, subdivision (a), the City finds that “none of the conditions described in Section 15162 calling for preparation of a subsequent FEIR or negative declaration have occurred.”
ENVIRONMENTAL DETERMINATION:

In reviewing the site specific information provided for this project and acting as Lead Agency, the City of Roseville, Development Services Department, Planning Division has analyzed the potential environmental impacts created by this project and determined that the findings of CEQA Section 15162 concerning the decision not to prepare a subsequent EIR or negative declaration and the findings of CEQA Section 15164 concerning the decision to prepare an Addendum can be made. As supported by substantial evidence within the Addendum to the Blue Oaks Commerce Center Mitigated Negative Declaration (Adopted May 27, 2010), the Lead Agency makes the following findings:
[ X ] No substantial changes are proposed in the project which would require major revisions of the previous EIR or Mitigated Negative Declaration.
[ X ] No substantial changes have occurred with respect to the circumstances under which the project is undertaken.
[ X ] There is no new information of substantial importance which was not known and could not have been known with the exercise of due diligence at the time the previous EIR was certified as complete or the Mitigated Negative Declaration was adopted.

DRAFT TECHNICAL MEMORANDUM
Date: July 26, 2022
To: Jack Varozza, PE, City of Roseville
From: John Gard, PE, RSP1, Fehr & Peers
Subject: Focused Access Evaluation for Blue Oaks Commerce Center RS22-4207
This memorandum presents the data collection, analysis, and recommendations of our focused access review of Blue Oaks Commerce Center (BOCC), which is situated south of Blue Oaks Boulevard and east of Industrial Avenue in the City of Roseville (refer to Figure 1 for project location). Our review specifically focuses on two driveways planned on Industrial Avenue that would serve the project’s industrial uses. The remainder of this memorandum is organized into the following sections:

I. Existing Conditions
II. Project Travel Characteristics
III. Project Access Review
IV. Recommendations
I. Existing Conditions
Roadway Network
The following roadways would provide direct vehicular access to the BOCC:

Industrial Avenue – is a two-lane north-south collector street that begins at Washington Boulevard and extends northerly through Roseville into unincorporated Placer County. Along the project frontage, it has a posted speed limit of 45 miles per hour (mph). The travel lanes are divided by either left-turn pockets or a paved median. Industrial Avenue parallels SR 65 between Roseville and Lincoln and is a time-competitive alternate route when SR 65 becomes congested.

Freedom Way – is a two-lane east-west street that begins at Industrial Avenue and terminates at Washington Boulevard. Along the project frontage, it has a posted speed limit of 40 mph and two undivided 16-foot wide travel lanes.

Fidelity Way – is a two-lane north-south street that begins at Blue Oaks Boulevard and terminates at Freedom Way. Along the project frontage, it has a posted speed limit of 30 mph and two undivided 16-foot wide travel lanes. Movements at the Blue Oaks Boulevard/Fidelity Way intersection are controlled by a traffic signal, though northbound left-turns are prohibited.

Industrial Avenue/Freedom Way Intersection
This T-intersection is controlled by a traffic signal. The southbound left-turn movement operates with a flashing yellow arrow, which requires motorists to yield to oncoming traffic (see Image 1). If southbound motorists are required to wait in the left-turn lane for an extended period of time (while waiting to find a gap in northbound traffic), the flashing yellow arrow changes into a solid green arrow, converting the southbound left-turn from a permitted to protected movement.

Image 1: Flashing yellow arrow for southbound left-turn lane on Industrial Avenue Truck Routes
Within the City of Roseville, there are two types of truck routes: Surface Transportation Assistance Act (STAA) routes and local routes. STAA routes allow large trucks to operate on the interstate freeway system and certain primary routes. These trucks, referred to as STAA trucks, are longer than California legal trucks. On surface streets, STAA routes are designated either as Terminal or Service Access routes.

Terminal routes are approved by the agency with jurisdiction over the roadway to enable the truck to reach its ultimate destination. Service Access routes allow STAA trucks to exit the interstate onto a local road, for one mile only, for food, fuel, lodging, or repair.

According to the City of Roseville website1
, STAA Terminal routes exist on Industrial Avenue along its entire length within the City. An STAA Terminal route also exists on the entirety of Fidelity Way. A

California legal truck route exists on the entirety of Freedom Way. Thus, a variety of established truck routes are located in the immediate proximity of the project site. Based on June 2022 traffic counts (described in detail below), trucks constitute about 8% of AM peak hour traffic and 3% of PM peak hour traffic at this intersection.

Traffic Volumes
Traffic volumes on Industrial Avenue and Freedom Way were collected from the City’s ITS traffic count database for Tuesday – Thursday, May 10-12, 2022. Schools were in session at the time of the counts.

The average daily traffic across the three weekdays was 11,200 vehicles on Industrial Avenue north of Freedom Way and 8,100 vehicles south of Freedom Way. Freedom Way east of Industrial Avenue carried 4,800 daily vehicles.

Traffic volumes during the AM and PM peak periods at the Industrial Avenue/Freedom Way intersection were also obtained from the City’s ITS traffic count database for the same three days in May 2022. The busiest hour of travel during the morning occurred from 7:45 to 8:45 AM. The busiest hour of travel during the evening occurred from 4 to 5 PM. Figure 2 shows the existing AM and PM peak hour traffic volumes (averaged for the three days), lane configurations, and traffic control at this intersection.

The City’s ITS count database does not provide data regarding vehicle queue lengths. Accordingly, Fehr & Peers retained NDS to conduct traffic volume and maximum queue length counts on several different weekdays in June and July 2022. The first count was conducted on Wednesday, June 29, 2022 and yielded an unexpectedly high southbound left-turn volume of 458 vehicles from 4-5 PM.2 Because of this anomaly, a second set of observations was conducted from 4-5 PM on Thursday, July 7, 2022.

One last observation was made on Monday, July 11, 2022. Table 1 shows the results of these data collection efforts.

2 The City’s ITS count database was queried and showed a near identical southbound left-turn volume as the traffic count, indicating the observation was not erroneous. The ITS count database showed that midweek volumes tend to be in range of 180 to 240 vehicles per hour. The anomaly on this particular day could have been caused by any number of atypical conditions such as severe SR 65 congestion resulting in diverted traffic to Industrial Avenue, construction activity, special events, or other effects.

On Wednesday, June 29, 2022, a maximum queue of five vehicles was observed during the PM peak hour. One incidence of this queue is shown in Image 2 based on the camera placed at the intersection by NDS. During the observation period on Monday, July 11, 2022, a maximum queue of five vehicles was also observed as shown in Image 3.

Neither video nor photography were available for the count on Thursday, July 7, 2022. NDS staff confirmed the accuracy of this data with the technician who performed the observations.

It is apparent from field observations, review of video collected on June 29, 2022, and the observed maximum queues themselves that many factors (beyond simply the left-turn volume) affect the number of vehicles queued in the southbound left-turn lane. Following is a list of those factors:

1. Level of northbound through/right traffic – these vehicles have the right-of-way and prevent southbound left-turns from occurring.

2. Random versus platooned arrivals on southbound Industrial Avenue – in some instances, vehicles arrived in large platoons (caused by a slow traveling lead vehicle). This quickly filled up the left-turn lane.

3. Driver uncertainty – some motorists appeared unfamiliar with the flashing yellow indication, waiting in the turn lane despite no approaching northbound traffic.

In summary, with respect to vehicle queues in the southbound left-turn lane, maximum queues of 5 vehicles during the PM peak hour are typical, though longer queues can develop under certain conditions (as was evidenced on July 7th). Additionally, since Industrial Avenue and Freedom Way are truck routes, trucks comprise a portion of the left-turn demand. As shown in Image 2, the maximum queue on June 29th included a truck, thereby resulting in a queue that was about 175 feet long.3

Collision History
City of Roseville staff provided data from its collision database for the segment of Industrial Avenue between the Blue Oaks Boulevard overcrossing and Galilee Road for the four-year period from June 2018 to June 2022. Table 2 shows the results. Note that the southbound left-turn flashing yellow arrow had been installed prior to 2018.

This table shows 9 total collisions at the Industrial Avenue/Freedom Way intersection over the fouryear period. Injuries were reported for 7 of the 9 collisions, but no fatalities occurred. The majority (6 of 9) were multi-vehicle broadside collisions involving southbound left-turn and northbound through motorists. No collisions involved bicyclists or pedestrians. Additionally, no collisions were reported along Industrial Avenue immediately north or south of the intersection.

3 Note that the 5th vehicle in the queue was positioned north of the terminus of the northbound Class II bike lane. The rear bumper of that vehicle was positioned about 180 feet north of the southbound leftturn stop bar, meaning that queued vehicles occupied an average of 36 feet of turn lane space. This is due to the truck that was present and the nature of the permissive left-turn, which tends to result in more of a “rolling queue” versus a stationary queue.

II. Project Travel Characteristics
Project Land Uses and Access
The portion of the BOCC under study is shown on Figure 3. As shown, this portion of BOCC is situated east of Industrial Avenue on both sides of Freedom Way. According to the site plan (source: Blue Oaks Commerce Center, VLMK Engineering+Design, March 2022), the following land uses are planned on each parcel:
• North Parcel – two industrial buildings with a total of 119,000 square feet of floor space. • South Parcel – two industrial buildings with a total of 189,280 square feet of floor space.

In total, the two parcels would comprise 308,280 square feet of industrial space.

A total of 7 driveways would serve the two parcels. Driveways 1 and 2 would be situated along Industrial Avenue, driveways 3 through 6 would be situated on Freedom Way (directly opposite each other), and driveway 7 would be situated on Fidelity Way. This study analyzes what turning movements should be allowed at Driveways 1 and 2. For analysis purposes, both driveways are assumed to permit all turning movements so as to understand travel demands, queuing, etc. under this condition.

Driveways 1 and 2 are described in more detail below:
• Driveway 1 on Industrial Avenue – has already been constructed with curb returns and driveway apron in place. It is situated 215 feet north of Freedom Way.4 The driveway would be 40 feet wide, consist of a 100-foot throat depth, and have curb return radii of 20 feet. A northbound 120-foot right-turn deceleration lane is present. The southbound left-turn at the Industrial Avenue/Freedom Way intersection is 260 feet in length and extends beyond this driveway. • Driveway 2 on Industrial Avenue – has already been constructed with curb returns and driveway apron in place. It is situated 275 feet south of Freedom Way and 340 feet north of the driveway serving 8880 Industrial Avenue.
5 The driveway would be 40 feet wide, consist of a 100-foot throat depth, and have curb return radii of 20 feet. The driveway is situated along a section of Industrial Avenue that has a continuous 650-foot northbound acceleration/deceleration lane that becomes a right-turn lane at Freedom Way. The median of Industrial Avenue is paved with a width of 12 feet in the driveway vicinity.

The following page shows photos of each driveway.

Trip Generation
The “Industrial Park” (Land Use Code 130) category from the Trip Generation Manual, 11th Edition (ITE 2021) was chosen to estimate the project’s trip generation and is defined as follows:

An industrial park contains several individual industrial or related facilities. It is characterized by a mix of manufacturing, service, and warehouse facilities with a wide variation in the proportion of each type of use from one location to another. Many industrial parks contain highly diversified facilities. Some parks in the database have a large number of small businesses and others have one or two dominant industries.

Table 3 shows the project’s estimated weekday AM and PM peak hour trip generation. As shown, the North and South parcels would generate a combined 104 trips during each of the AM and PM peak hours. Trips during these two periods would be highly directional, with about 80% being inbound in the AM peak hour and outbound during the PM peak hour.

Data from the Trip Generation Manual also provides insights into the relative amount of passenger vehicle versus truck traffic at industrial parks. ITE data includes truck trip rate data and total trip rate data for three specific sites. Key findings from this data were:
• During the AM peak hour, trucks ranged from 11 to 13 percent of total trips at the three sites, for an average of 12 percent trucks.
• During the PM peak hour, trucks ranged from 4 to 12 percent of total trips at the three sites, for an average of 8 percent trucks.

This suggests that about 10 trucks are expected to enter/exit the two parcels during each peak hour.

Trip Distribution
Table 4 displays the project’s estimated trip distribution. As shown, separate distribution percentages were derived for passenger vehicles (i.e., primarily employee trips) versus trucks. Whereas passenger vehicles are expected to be generally oriented in proportion to the location of residences, truck trip distribution is more aligned with truck routes and key destinations.

As shown, an estimated 15% of project trips would be distributed to/from the north on Industrial Avenue. Industrial Avenue is expected to be utilized by 20% of outbound project trips to travel westbound on Blue Oaks Boulevard (via Alantown Drive) toward Foothills Boulevard.

Trip Assignment
It is unlikely that project trips distributed to/from the east (i.e., on SR 65 or Washington Boulevard) would use project driveways situated on Industrial Avenue given the proximity and convenience of other more easterly driveways.

Conversely, it is also possible that some trips destined for Industrial Avenue will choose to use driveways on Fidelity Way or Freedom Way, which carry considerably less traffic compared to Industrial Avenue. The traffic assignments that follow consider these behaviors.

Figure 4 shows the existing plus project volumes at the Industrial Avenue/Freedom Way intersection and Driveways 1 and 2 on Industrial Avenue. As shown, Driveways 1 and 2 would each carry 15 or fewer vehicles per hour. The project would cause very modest changes in traffic volumes at the Industrial Avenue/Freedom Way intersection.

III. Project Access Review
The project access review focuses on the following project driveway aspects:

1. Sight distance analysis for southbound left-turn at Driveway 1

2. Maximum queue lengths at Driveways 1 and 2

3. Conflict points in southbound left-turn lane on Industrial Avenue at Driveway 1 Sight Distance Analysis for Southbound Left-Turn at Driveway 1 Motorists desiring to turn left into Driveway 1 could encounter sight distance limitations due to southbound queued vehicles in the Industrial Avenue/Freedom Way southbound left-turn lane. Since Industrial Avenue is posted with a 45 mph speed limit, a design speed of 50 mph was selected for the analysis. Figure 5 shows that under conditions present in Image 5 (i.e., queue of 5 vehicles including one truck), a southbound left-turning vehicle at Driveway 1 would have 375 feet of available sight distance. This is less than the 440 feet required (refer to Figure 5 for calculation details). Thus, insufficient sight distance would be provided for the southbound left-turn into Driveway 1.

Maximum Queue Lengths at Driveways 1 and 2
The modest volumes (15 vehicles per hour or less) turning into and out of Driveways 1 and 2 suggest that maximum queues would typically be one or two vehicles. Both driveways would have throat depths of 100 feet, which is sufficient for either four passenger vehicles, or one truck and one passenger vehicle.

It is possible to stripe a 175-foot southbound left-turn lane in the Industrial Avenue median serving Driveway 2. This would provide adequate stacking for vehicles turning into this driveway.

Conflict Points in Southbound Left-Turn at Driveway 1
Field observations revealed many motorists on southbound Industrial Avenue enter the Freedom Way left-turn at its beginning (versus merging into the lane 100 feet further south for instance). This behavior is especially common among motorists who are following a slower lead vehicle. If southbound left-turns were permitted at Driveway 1 within this turn lane, continuing southbound motorists would encounter vehicles stopped in the turn lane, waiting to turn into Driveway 1. This would introduce a clear and obvious conflict area, which could lead to an increase in rear-end collisions.

Additionally, since queued left-turning vehicles already spill back to Driveway 1, it would not be possible to stripe separate left-turn lanes serving both Driveway 1 and Freedom Way.

IV. Recommendations
Based on the data and analyses presented in this memorandum, the following recommendations are offered at each driveway:

Driveway 1

1. Restrict inbound and outbound movements to right-turns only by constructing a narrow, raised curb on the east edge of the median/left-turn lane. The raised curb would begin 100 feet north of the driveway centerline and end 75 feet south of the driveway centerline. 6 2. Post a One Way Only sign within the raised curb visible to vehicles exiting Driveway 1.

3. Post a No U-Turn sign at the north end of the raised curb or in the adjacent median.

Driveway 2

1. Stripe a 175-foot southbound left-turn lane within the paved median to serve this driveway.

2. Permit all turning movements.

6 A raised curb could be constructed similar to what exists on portions of Hazel Avenue (STAA route) north of Oak Avenue in Sacramento County. The recommended extents of the raised curb consider the minimum distance required to deter direct left-turns, while also not extending the raised curb an excessive distance.

Biological Resources Letter Report
Blue Oaks Commerce Center ‐ 2200 Freedom Way
December 2022

SUMMARY
Schnitzer Properties(Owner) is proposing to complete development of the 575,505 square foot Blue Oaks Commerce Center office, industrial and retail complex (project). The City of Roseville approved the Blue Oaks Commerce Center in 2010. The Owner constructed the first project building in 2015/2016. The Owner proposes to modify the Project to complete the development of four buildings totaling approximately 310,000 square feet. Project activities would occur within Sections 21 & 22, Township 11N, Range 06E, within the Roseville USGS 7.5' Quad, Placer County Assessor’s Parcel Number (APN) 017‐123‐ 090. (Attachment A: Figure 1 – Location Map)
Original project activities were evaluated and approved under an Initial Study/Mitigated Declaration (IS/MND). The IS/MND identified three biological Mitigation Measures(MMs) to mitigate potential project impacts. The mitigation measures generally included the requirement to obtain regulatory permits for habitat elimination, issuance of a grading permit and coverage under the CA Construction General Permit (CGP), and pre‐construction presence/absence species surveys prior to construction.

After a thorough evaluation of original project documents, species data from multiple sources, and a site visit conducted by principal biologist Carol Adema to document present day site conditions; the Project biologist concluded that no new or significantly increased environmental impacts would occur secondary to the re‐initiation of project activities. As such, no additional MMs beyond those identified in the original project IS/MND will be necessary, though the timing windows mentioned in MM BIO#3 have been updated to reflect present day standards, as discussed in the Conclusions and Recommendations Section.

PROJECT HISTORY & DESCRIPTION
The City of Roseville circulated the IS/MND for public review on April 29, 2010 (SCH# 2010042089), closing for comment on May 29, 2010. Project activities commenced in September 2014 with initial site preparation and grading, including the removal of naturally occurring aquatic features within the entirety of the site, removal of a portion of roadway located on the northwest corner of the project area, installation of stormwater treatment swales along the western border of the property, and concluding in 2017 with the construction of a Federal Bureau of Investigation campus on the southeast corner of the property.

As required by the MMs, the Owner obtained regulatory permits from the U.S. Army Corps of Engineers (USACE), the U.S. Fish & Wildlife Service (USFWS), the CA Regional Water Quality Control Board (RWQCB) (for both Clean Water Act (CWA) and CGP), and the CA Department of Fish and Wildlife. Mitigation credits were then purchased, as stipulated by agency permits. (Appendix A: Regulatory Permits and Proof of ATTACHMENT 3
RE: Biological Resources Letter Report – December 2022 Blue Oaks Commerce Center (APN 017‐123‐090)

Page 2 of 11 ends

Mitigation Purchase) Prior to re‐initiation of ground disturbing activities during the migratory bird breeding season, a pre‐construction survey was conducted by a qualified biologist with negative findings. (Appendix B: Pre‐construction Survey Report)
Initial grading and compaction of the undeveloped portion of the site eliminated all 2.028 acres of naturally occurring on‐site aquatic features and resulted in the installation of stormwater treatment swales along the western border of the property.

The proposed project will allow the development of four industrial buildings totaling approximately 310,000 square feet in size with associated parking, lighting, and landscaping.

PROJECT SPECIFIC IS/MND BIOLOGICAL MITIGATION MEASURES
 MITIGATION MEASURE BIO#1: Prior to the issuance of a grading permit or approval of improvement plans and prior to the filling of any potential wetlands or waters of the US as identified in the wetland delineation, the applicant shall obtain appropriate permits from the US Army Corps (anticipated to be an Individual Permit). Additionally, a Clean Water Act Section 401 permit shall be obtained from the Central Valley Regional Water Quality Control Board (CVRWQCB) to ensure the proposed discharge complies with all State water quality requirements. Additionally, a Fish and Game Section 1601 permit shall be obtained for streambed alterations that are regulated by Fish & Game. The project shall implement the mitigation requirements of these permits to ensure no net loss of wetlands/waters of the US.
 MITIGATION MEASURE BIO#2: Prior to grading and excavation activities on‐site, the developer shall obtain a grading permit to ensure that the project is in compliance with the City’s (Roseville) best management practices for water quality control and the Storm Water Pollution Prevention Plan (SWPPP).
 MITIGATION MEASURE BIO#3: A qualified biologistshall perform pre‐construction surveysfor nesting birds and raptors at least 30 days in advance of construction if construction is planned during January to July. If the survey does not identify any special‐status birds or raptors species, no further mitigation is required. If nesting is found to be occurring, avoid disturbance of the nest site with a suitable buffer zone. The on‐site biologist shall consult with the California Department of Fish & Game to determine the size of the no‐disturbance buffer (typically between 150 to 200 feet). Additionally, if Swainson’s hawk are found to be using the site in any capacity, off‐site mitigation would be required at a ratio deemed suitable by the CDFG.

METHODS
On December 15, 2022, principal biologist Carol Adema conducted a survey for biological and aquatic resources present on‐site within the Biological Survey Area (BSA). The nearly 26‐acre BSA was created by buffering the project area a distance sufficient to analyze project impacts on adjacent resources (approximately 250‐500 feet). The survey took place from approximately 1200‐1600; conditions were cold and sunny with temperatures ranging from the mid‐ to upper‐50’s with a very slight north breeze. The results of the site survey and data analysis are provided and discussed on pages 4‐9 of this letter report.

RE: Biological Resources Letter Report – December 2022 Blue Oaks Commerce Center (APN 017‐123‐090)

Page 3 of 11 ends

Prior to conducting the surveys, past environmental survey reports, maps and documents, existing databases, topographic maps, soil reports, and multiple years of aerial imagery of the BSA were reviewed, and areas of potential habitat noted. Additionally, after conducting the surveys, agency special‐status species lists were reviewed, considering existing conditions observed within the BSA both during the season surveyed as well as all other times of year.

Ms. Wallen obtained lists of special‐status habitats and/or species potentially occurring in the vicinity of the BSA from the USFWS Information for Planning and Consultation (IPac) as well as the USFWS National Wetlands Inventory (NWI). Additionally, a 5‐mile project buffer was applied to execute a search of the CDFW California Natural Diversity Database (CNDDB), while a 9‐quad search (Sheridan, Pleasant Grove, Lincoln, Gold Hill, Rocklin, Citrus Heights, Roseville, Rio Linda, and Folsom) was utilized to query the California Native Plant Society’s (CNPS) Online Rare and Endangered Plant Inventory. The agency lists are provided as Appendix C: Supporting Agency Species Lists. A map of CNDDB occurrences within 5 miles of the project area may be found as Attachment A: Figure 2 ‐ CNDDB Map.

Ms. Wallen conducted a biological survey of the project area and surrounding habitat to examine the site for potentially sensitive biological resources. Survey methodology involved traversing meandering transects through the project area and surrounding habitat where accessible. The surveys were general in nature and were conducted to determine the presence/absence of special‐status species and/or habitats within the BSA and to determine if these resources would be impacted by proposed project activities. After reviewing the original wetland delineation map, areas which had been identified as aquatic habitat prior to site alteration were specifically inspected and evaluated to ensure past features had reestablished. (Attachment A: Figure 3 – Original Wetland Delineation Map) A list of species encountered during the survey is included as Attachment B: Observed Species List and are discussed in the “Results” section.

Following the field survey, the “potential for occurrence” was determined based on the quality and types of habitats observed on‐site. This discussion may be found in the “Results” Section. For plants, assuming suitable habitat is on‐site, potential for occurrence is considered during the appropriate flowering period.

For birds and bats, the potential for occurrence is considered during the appropriate timeframes when these species breed, forage, roost, over‐winter, or stop‐over in the BSA during migration. Any bird or bat species could fly over the BSA; however, this is not considered a potential for occurrence as it would not result in any impact. The categories for the potential for occurrence include:
 None: The species or natural community is not known to occur and has no potential to occur in the BSA based on sufficient surveys, the lack of suitable habitat (including soil, vegetation, connectivity, etc.), and/or the BSA is well outside of the known distribution of the species.  Low: Potential habitat in the BSA is sub‐marginal and the species is not known to occur in the vicinity of the BSA. Protocol‐level surveys are not recommended.  Moderate: Suitable habitat is present in the BSA and the species is known to occur in the vicinity of the BSA.
 High: Habitat in the BSA is highly suitable for the species and there are reliable records close to the BSA, but the species was not observed.
 Known: The species or natural community was detected in the BSA or a recent reliable record exists for the BSA.

EXISTING SITE CONDITIONS
The proposed project area is characterized as vacant, undeveloped land in the southwestern portion of the City of Roseville. The project area is located on the southeast corner of Blue Oaks Blvd. and Industrial Ave. and is bisected by Freedom Way; all observed to have consistent traffic moving quickly during the time of survey. The project area is bordered to the south by an industrial complex and to the east by an office complex and undeveloped field. There is also a rail line located immediately to the west of the site.

There are four man‐made vegetated stormwater receiving swaleslocated along the western border of the project area. These areas appear to be in the process of establishing some riparian vegetation, as designed, to treat site runoff water. Additionally, the swale areas are lined with an erosion control fabric that allows root establishment but prevents rodent burrows. As such, no burrows were observed within the stormwater swale areas.

The topography within the project area is characterized as nearly flat, with a gently sloped landscape south and north toward Freedom Way then heading westtoward the stormwater receiving swale systems.

Secondary to site grading, habitat elimination, and compaction, no wetland features occupy the project site. Additionally, no small mammal burrows or residual soil/spoil mounds were observed anywhere within the site boundaries.

California habitat types are described in the California Wildlife Habitat Relationships(CWHR)system based on classifications created by Mayer and Laudenslayer (1988). The CWHR system was designed to aid in the mapping of habitats utilized by California’s commonly occurring birds, mammals, reptiles, and amphibians. Aside from the created stormwater drainage swale areas, a single habitat type is present within the project area: Annual Grassland, which is described in further detail below. Representative site photos may be found in Attachment C: Site Photos.

Annual Grassland:

Annual Grassland habitat occurs throughout the entire project area. It is comprised mostly of sparse non‐ native annual grasses and herbaceous plant species; likely due to drought conditions combined with the compacted nature of the on‐site soil post‐grading. Annual grassland habitats can be found throughout California and are found on flat plains to gently rolling foothills. Annual grasslands are described as open grasslands composed primarily of annual plantspecies and often consist of a variety of introduced invasive species. Species composition isstrongly influenced by abiotic factors and compositional changesfluctuate seasonally due to the phenology of plants found within an area. Species commonly found within annual grasslands include wild oats (Avena fatua), ripgut brome (Bromis diandrus), red brome (Bromus madritensis), soft chess (Bromus hordeaceus), wild barely (Hordeum spp.), foxtail fescue (Vulpia myuros), filaree (Erodium spp.), and various clovers (Trifolium spp.) among others.

A number of wildlife species may use annual grasslands for breeding and foraging if the habitat issuitable.

RESULTS
A table analyzing the potential for presence of a special‐status species identified by resources agencies within the project area can be found in Attachment D: Special Status Species Table. As stated before, a list of species observed during the survey may be found in Attachment C: Observed Species List. Only RE: Biological Resources Letter Report – December 2022 Blue Oaks Commerce Center (APN 017‐123‐090)

Page 5 of 11 ends

species with a known or historical presence on‐site, that are state or federally listed, or with a moderate or high potential to occur on‐site are analyzed below as part of the Results Section.

The following narrative focuses on a combination of site observations as well as the species identified in agency lists and their potential to occur within the project area. Species and habitat which originally occurred within the project area have been accounted and mitigated for as part of the original Project permitting effort. The IS/MND included applicable MMsthat addressspecial‐status migratory bird species with potential to occur within the project area. There are no critical habitats within the project area.

Sensitive Natural Communities
No sensitive natural communities(SNCs) were determined to occur within the BSA. Prior to alteration, the projectsite hosted vernal pool, wetland, intermittent drainage, and marsh areas. However, grading of the site in 2014 successfully eliminated these features, in accordance with applicable regulatory permits. (Appendix A ‐ Regulatory Permits) Additionally, though listed as having once occurred within 5 miles of the project area in the CNDDB list, the site does not contain Alkali SNCs, nor is it adjacent to any Alkali sources/influences.

Secondary to site grading, habitat elimination, and compaction, the site has not re‐established any wetland features or any other type of SNC.

Plants
The USFWS IPac listed no potential for federally listed plants within the project area, however, the CNPS list does include Sacramento orcutt grass.

Prior to site alteration, special status plant surveys were conducted on May 15 and June 26, 2006 with negative results for listed species. The December 2022 site visit, though not during the flowering window, shows the site to be inundated with the skeletal remains of invasive species such as medusahead (Elymus caput‐medusae) and star thistle (Centaurea solstitialis). Other species observed on‐site included common tarweed (Hemizonia pungens) and hairy hawkbit (Leontodon saxatilis). No wetland plant species were detected within the project area.

The USFWS evaluated the site for occurrence potential for Sacramento orcutt grass (Orcuttia viscida) and slender orcutt grass (Orcuttia tenuis). (Appendix A5: USFWS Concurrence) On March 18, 2008 the USFWS concluded that,
“The Special‐Status Plant Survey did not identify either species occurring on the site, and the Service has determined that the survey was done adequately to demonstrate absence of these species. Therefore, the Service concurs that the proposed project as proposed is not likely to adversely affect the Sacramento orcutt grass and slender orcutt grass.” The present day, post‐grading and habitat elimination yields site conditions consisting of no wetland or vernal pool features. Therefore, in accordance with the USFWS, as no new information has revealed effects of the proposed action that may affect listed species in a manner or to an extent not considered, no new species with potential to occur within the site have been listed, no critical habitat has been designated that may be affected by the proposed project. There are no project description changes that would change a level of potential effect on biological resources. No further action pursuant to the Endangered Species Act is necessary. Similar to the federal ESA, with no habitat or individuals occurring historically and with habitat elimination in 2014 with present day‐maintenance, there is no potential for RE: Biological Resources Letter Report – December 2022 Blue Oaks Commerce Center (APN 017‐123‐090)

Page 6 of 11 ends

state‐listed endangered or threatened species to occur on‐site, and as such coverage under Section 2080 or 2081 of CESA is not warranted.

Invertebrates
Five federally listed invertebrates were found on the official USFWS IPac list: Monarch butterfly (Danaus plexippus) [Candidate], valley elderberry longhorn beetle (VELB) (Desmocerus californicus dimorphus) [Threatened], conservancy fairy shrimp (Branchinecta conservatio) [Endangered], vernal pool fairy shrimp (Branchinecta lynchi) [Threatened], and vernal pool tadpole shrimp (Lepidurus packardi) [Endangered], collectively, vernal pool crustaceans.
 Monarch butterfly: The Monarch overwintersin the coastal CA region and may passthrough the region during migrations. The Monarch relies heavily on milkweed and flowering species during migration and breeding. While the site may have provided some flowering plants priorto wetland feature elimination, in its currently maintained state, there is no potential habitat for breeding or foraging monarchs.  Valley Elderberry Longhorn Beetle: The VELB is found exclusively in blue elderberry (Sambucus nigra spp. caerulea) shrubs in California’s Central Valley where the species utilizes the shrubs for all life stages. Females will lay eggs on the bark of the shrub where they hatch and the larvae will bore into a stem where it will live for one to two years, feeding on the pith. After developing, an adult beetle will exit the stem and emerge to seek a mate. The adults are not particularly strong fliers and do not appear to disperse very far.

There are no elderberry shrubs are present within the BSA, nor within a distance of work to be impacted. The nearest occurrence of VELB occurrence to the project area is approximately 3.8 miles to the west in the foothill canyon areas. Both historically and in its currently maintained state, there is no potential habitat for VELB in any life stage and therefore no potential for impact.  Vernal Pool Crustaceans: Vernal pool fairy shrimp, vernal pool tadpole shrimp, and conservation fairy shrimp are federally listed and as their name suggests, are dependent upon vernal pool environments.

According to a March 18, 2008 USFWS Letter (Appendix A5 – USFWS Concurrence), “Service guideline‐level wet season surveys were completed during the 2005‐2006 and 2006‐ 2007 seasons to determine the status of the vernal pool crustaceans on the project site. The Service has determined that, based on the methods and results outlined in the 90‐day reports, the surveys were performed adequately and the conditions on the site were appropriate to demonstrate absence of these species on the project site. Therefore, the Service concurs that the proposed project as proposed is not likely to adversely affect the vernal pool crustaceans.” The above pre‐construction USFWS designation combined with post‐site alteration conditions that yield no vernal features on‐site, confirm there is no potential for vernal pool crustaceans within the project area. Furthermore, now that all vernal features have been removed, there is no potential for vernal pool crustaceans within the site.

Fish
The only federally listed fish species found on the official USFWS list is delta smelt (Hypomesus transpacificus). Central Valley steelhead (Oncorhynchus mykiss) is found on the CDFW CNDDB list. Delta RE: Biological Resources Letter Report – December 2022 Blue Oaks Commerce Center (APN 017‐123‐090)

Page 7 of 11 ends

smelt are confined to the Delta region of CA in estuary habitats. Central valley steelhead are found on the Sacramento River and its tributaries, favoring cold and clean water for holding and spawning.

An original feature on‐site was an intermittent drainage, but it was incapable of supporting Central valley steelhead. Present day conditions, where the intermittent drainage has been converted to man‐made stormwater treatment swales, has further eliminated this area as potential habitat for the lone federally listed species found on the agency lists. Therefore, there is no potential for the species to be affected by the proposed project.

Reptiles and Amphibians
No federally listed species were found on the official USFWS IPac list. One special‐status species was returned by the CNDDB search: the western spadefoot toad (WST) (Spea hammondii).

The WST is a relatively small, smooth skinned toad, with white and orange tipped turbercles on its back, and distinctive vertical pupils. It is named for the sharp‐edged “spades” on its hind feet utilized for digging.

The species occupies grassland, sage scrub, and woodland habitats from Tehama County to Baja. The species is dependent on ephemeral pools or slow‐moving water courses that are predator free for breeding. Larval development can be rapid (approximately 30 days) if vernal pools are drying.

There are no vernal features or ephemeral waters found within the project area suitable to support the WST. Additionally, compacted soil would be difficult if not impossible for the WST to dig in, as noted by the absence ofsmall mammal burrows post‐grading and compaction. Therefore, the site does not provide suitable WST habitat.

Birds
No federally listed bird species were identified in the IPaC database search though it identified several listed as Birds of Conservation Concern (BCC) which are addressed in Attachment D. According to The USFWS, “Although the bird taxa included in the BCC 2021 are priorities for conservation action, this list makes no finding with regard to whether they warrant consideration for ESA listing.” (USFWS, 2021) A search of CDFW’s CNDDB identified occurrences of three state‐listed threatened species: the CA black rail (CBRA) (Laterallusjamaicensis coturniculus), the tricolored blackbird (TRBL) (Agelaiustricolor), and the Swainson’s Hawk (SWHA) (Buteo swainsoni).
 CA Black Rail: The CBRA is known to inhabit saltwater, brackish, and freshwater marshes. In California, the San Francisco Bay/Delta region has all three types of marshes. Vegetation of CBRA marshes varies from almost pure pickleweed (Salicornia sp.) to sedges (Carex sp.) and saltgrass (Distichlis sp.) to bulrush (Scirpus sp.) and cattails (Typha sp.). In San Francisco Bay marshes the presence of the CBRA is associated with relatively high values for vegetation height, Frankenia (alkali‐heath) abundance, and insect abundance, but with low values of amphipod abundance (Evens et al. 1986).

The lone occurrence of CBRA within 5 miles of the project area was a single adult male in 2006 located 4.9 miles west of the project area adjacent to Clover creek. Based on the lack of suitable foraging or breeding habitat combined with a lack of known occurrences adjacent to the site, project activities would not result in impacts to the CBRA.

RE: Biological Resources Letter Report – December 2022 Blue Oaks Commerce Center (APN 017‐123‐090)

Page 8 of 11 ends

 Tricolored Blackbird: Current TRBL species studies indicate that primary foraging habitats for TRBL during the breeding season include grasslands, low density shrublands (e.g., alkali scrub), pastures, dry seasonal pools, and certain agricultural crops including alfalfa and rice”. (CDFW, 2018) Tricolors will not settle without access to open water and dominant nest substrate species for TRBL include cattails, bulrushes, Himalaya blackberry, and agricultural silage. Although other plant species are used as nesting substrate, all are either flooded, spinous or otherwise defended against easy access by predators. Strips of emergent vegetation along canals are typically avoided as nest sites. If sites are hard for an observer to reach, the site it is relatively suitable. (Hamilton, 2004) Studies have also found that, “While breeding, most foraging occurs within 2–3 miles (3.2 ‐ 4.8 km) of colony sites.” (Orians 1961, Hamilton et al. 1992)
Current site conditions do not support nesting or suitable foraging habitat and no suitable nesting habitat or open water exists within 3 miles of the project area. The nearest known occurrence of TRBL to the site is approximately 4 miles to the north. The fact that the site lacks suitable nesting or foraging habitat combined with the distance to the nearest known siting which has not been active since 2015 indicate there is no potential for TRBL, and therefore no potential for project impacts to TRBL.
 Swainson’s Hawk: SWHA breeding habitat includes annual grassland areas with scattered trees, large shrubs and is found peripheral to riparian areas. They will often feed in agricultural areas (Goodrich and Smith 2008, p. 120). Young are fed rodents, rabbits, and reptiles. However, when not breeding, adults feed almost exclusively on insects, primarily grasshoppers (Bechard et al. 2010).

Areas they inhabit require at least small tracks of adjacent land containing lightly irrigated agricultural areas particularly with alfalfa and grass hay, or non‐agricultural areas with low or moderate height vegetated areas (Wheeler 2003, p. 274).

Current site conditions are not conducive to breeding rodent populations and are not adjacent to agricultural areas. No rodents or other small mammals were observed during the site visit and no evidence of established populations (burrows) were noted on‐site. This is likely due to soil compaction, which does not allow for burrowing or solid cover plant growth.

Due to a lack of suitable nesting trees or foraging habitat adjacent to or within the site, potential impacts to SWHA are unlikely.

Unlike the species listed above, the BSA may seasonally provide marginal foraging habitat for other avian species protected under the coverage offered by the MTBA. Although a few such species were observed during the survey (Attachment C: Observed Species), there was very little avian activity considering the time of day. This is likely due to consistent noise/disturbance from traffic and active railway to the west combined with the sparsely vegetated (and therefore highly exposed) nature of the site, which provides marginal to poor quality foraging habitat for smaller passerine species. This is likely due to the post‐site compaction nature of the site which contributes to sparsely vegetated landscape, as seeds have a hard time taking in compacted soil on exposed areas. The site offers poor quality foraging habitat for raptors in general as well; likely due to the lack of small mammal burrows, secondary to site compaction. No raptors nor any prey sourcesfor them (including roadkill) were observed during the field visit. No evidence of raptors utilizing the site for prey was detected (i.e. owl pellets, whitewash, down feathers, etc.).

Mammals
There were no special‐status mammalsfound on any of the agency lists. Some that have potential to occur within the general region, but outside the 5‐mile primarily consist of bat species such as hoary bat (Lasiurus cinereus), pallid bat (Antrozous pallidus), silver‐haired bat (Lasionycteris noctivangans), western mastiff bat (Eumops perotis), and Yuma myotis (Myotis yumanensis).

There is no potential roosting habitat on‐site and minimal potential roosting habitat located on properties adjacent to the project area for any of these species with the exception of building ledges as there are few trees, all of which are ornamental in nature, and no rocky cliffs found.

There is potential marginal to poor foraging habitat above the grassland within the BSA, however, it is of lower quality than the greater undeveloped areas to the north and wooded foothill areas to the east where a variety of habitats are present providing a more robust prey base.

Aquatic Resources
A wetland delineation was conducted for the entire original project area in 2005 and finalized in 2006 identifying 2.028 acres of aquatic features representing jurisdictional WOUS. The feature types were comprised of 9 vernal pool features (0.708 ac), 44 seasonal wetland features (0.687 ac), 7 seasonal swale features (0.246 ac), 3 seasonal marsh features (0.139 ac), and 2 intermittent drainage features (0.248 ac). (Attachment A: Figure 3 ‐ Original Wetland Delineation Map).

All features were permanently removed as a result of site grading which occurred in 2014 through 2017.

Present day site conditions indicate no wetland features have re‐established within the project area. Only man‐made stormwater treatment swales lie along the western border of the property, which will not be impacted by project work and are not jurisdictional.

CONCLUSIONS AND RECOMMENDATIONS
Present day recommendations from various regulatory agencies suggest that for the northern CA region, pre‐construction avian surveys should be conducted during the typical migratory bird breeding season from February 1 through August 31 to ensure nesting activities are not disturbed by construction activities. Additionally, surveys should be conducted no more than two weeks in advance of commencement of construction and should be repeated if a lapse in construction of two weeks or greater occurs.

With adherence to the MMs from the original IS/MND including minor modifications to the timing of surveys; impacts to special status species would be eliminated, minimized, and sufficiently mitigated.

Consequently, the proposed project would not result in any new significant biological resource impacts or in a substantial increase in the severity of the previously identified biological resource impacts described in the IS/MND. No additional mitigation measures are required.

Subject: Request for Concurrence on the Blue Oaks-Washington Project in Roseville, Placer County, California
Dear Mr. Jewell:

This letter aclrnowledges the U.S. Fish and Wildlife Service's (Service) November 6, 2007, receipt of the U.S. Army Corps of Engineers' (Corps) November 1, 2007, letter requesting initiation of section 7 consultation under the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.) (Act). The consultation concerns the possible effects of the proposed Blue Oaks-Washington project (proposed project) on two federally-listed species, the endangered vernal pool tadpole shrimp (Lepidurus packardi) and the threatened vernal pool fairy shrimp (Branchinecta lynchi) (collectively, the vernal pool crustaceans).

The findings and recommendations in this consultation are based on: O) the March 31, 2006, Information to Support Formal Section 7 Consultation, Blue Oaks-Washington Property, Placer County, California, prepared by ECORP Consulting, Inc. (ECORP); (2) the July 6, 2007, and July 24, 2007, Wet Season 90-day Reports of Findings Regarding Federally Listed Branchiopods for the proposed project; (3) the October 10, 2006, Special-Status Plant Survey for the proposed project; (4) various e-mails between Cynthia Hertzog ofECORP and Jana Milliken of the Service; and (5) other information available to the Service. A complete administrative record is on file at the Sacramento Fish and Wildlife Office.

The proposed project involves construction of a mixed commercial and industrial business park south of Blue Oaks Boulevard, between Washington Boulevard and Industrial Avenue ·near Roseville. According to the information provided, construction will necessitate the filling of

1.953 acres of seasonal wetland habitat.

Mr. Michael S. Jewell 2
Service guideline-level wet season surveys were completed during the 2005-2006 and 2006-2007 seasons to determine the status of the vernal pool crustaceans on the project site. The Service has determined that, based on the methods and results outlined in the 90-day reports, the surveys were performed adequately and the conditions on the site were appropriate to demonstrate absence of these species on the project site. Therefore, the Service concurs that the proposed project as proposed is not likely to adversely affect the vernal pool crustaceans.

Although not included in y.our initiation request, the proposed project site is within the range of ~d contains suitable habitat for the Sacramento orcutt grass ( Orcuttia viscida) and slender orcutt grass (Orcuttia tenuis). The Special-Status Plant Survey did not identify either species occurring on the site, and the Service has determined that the survey was done adequately to demonstrate absence of these species. Therefore, the Service concurs that the proposed project as proposed is not likely to adversely affect the Sacramento orcutt grass and slender orcutt grass.

Unless new information reveals effects of the proposed action that may affect listed species in a manner or to an extent not considered, a new species is listed or critical habitat is designated that may be affected by the proposed project, or if the project description changes, no further action pursuant to the Act is necessary.

If you have any questions or concerns regarding this consultation, please contact Jana Milliken or the Acting Sacramento Valley Branch Chief, at (916) 414-6645.

Sincerely,
Peter A. Cross
Deputy Assistant Field Supervisor

RE: Blue Oaks Commerce Center, City of Roseville, Placer County, California – Preconstruction Nesting Bird Survey
Dear Ms. Gray:

At your request, ECORP Consulting, Inc. (ECORP) conducted a nesting bird survey for the Blue Oaks Commerce Center project site located in the City of Roseville, Placer County, California.

The project site is bounded by Blue Oaks Boulevard on the north, Industrial Avenue on the west, and Washington Boulevard on the east. This survey included all trees and open areas located within the project site, and all suitable habitats within publicly accessible areas within 300 feet of the project.

The Federal Migratory Bird Treaty Act (MBTA) protects most naturally occurring birds (including common species) and makes it illegal to take, possess, export, transport, sell, purchase, barter or offer for sale, purchase, or barter any migratory bird, or the parts, nests, or eggs of such a bird except under the terms of a valid permits issued pursuant to Federal regulations. The California Fish and Game Code §3503 makes it unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by this code or any regulation pursuant thereto. All raptors (owls, hawks, eagles, and falcons), including their nests, are protected from take pursuant to the California Fish and Game Code §3503.5, and the MBTA, among other federal and state regulations. Potential tree-nesting raptors within this region include Great Horned Owl (Bubo virginianus), Red-tailed Hawk (Buteo jamaicensis), White-tailed Kite (Elanus leucurus), Cooper’s Hawk (Accipiter cooperii), and American Kestrel (Falco sparverius), among others. Potential ground-nesting raptors include Northern Harrier (Circus cyaneus) and Burrowing Owl (Athene cunicularia).

This survey was conducted via visual observation on March 19, 2015 by ECORP senior biologist Keith Kwan. Binoculars (10x40 magnification) and a spotting scope (20-60x magnification) were used to assist with field identification and observations. Trees were visually inspected from multiple angles for active nests, and transects were walked through open areas to locate potential ground-nesting species. Transects were spaced approximately 50 feet apart to ensure complete coverage.

During this survey, no active bird nests were found within the project site and the 300-foot survey area. The project site has been previously graded and treated with hydroseed erosion control. There are no trees on the project site, but several are located offsite, along Industrial Avenue in the industrial development to the south. A list of birds observed is included as Attachment A.

Cliff Swallows (Petrochelidon pyrrhonota) are beginning to nest under the Blue Oaks Boulevard overpass at Industrial Avenue, but these should not be affected by site construction, which is over 300 feet away.

In conclusion, no active bird nests were found during the survey conducted on March 19, 2015.

It is recommended that a follow up survey be conducted if no construction activity occurs within 14 days of this survey, as new nests could be built within the survey area at any time during this period.

If you have any questions feel free to contact me at (916) 782-9100.

Sincerely,
IL-£,__.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below. The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area.

However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site-specific (e.g., vegetation/species surveys) and project-specific (e.g., magnitude and timing of proposed activities) information.

Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of project level impacts.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site-specific and project-specific information is often required.

Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly.

For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following:

1. Draw the project location and click CONTINUE.

2. Click DEFINE PROJECT.

3. Log in (if directed to do so).

4. Provide a name and description for your project.

5. Click REQUEST SPECIES LIST.

Listed species and their critical habitats are managed by the Ecological Services Program of the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic and Atmospheric Administration (NOAA Fisheries ).

Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list. Please contact NOAA Fisheries for species under their jurisdiction.

1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows species that are candidates, or proposed, for listing. See the listing status page for more information. IPaC only shows species that are regulated by USFWS (see FAQ). 1 2

Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report.

Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4- week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high.

How is the probability of presence score calculated? The calculation is done in three steps:

1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.

2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.

3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.

To see a bar's probability of presence score, simply hover your mouse cursor over the bar.

Breeds Apr 1 to Jul 31
probability of presence breeding season survey effort no data Breeding Season ( )
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.

Survey Effort ( )
Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys.

To see a bar's survey effort range, simply hover your mouse cursor over the bar.

No Data ( )
A week is marked as having no data if there were no survey events for that week.

Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure.

To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the list of migratory birds that potentially occur in my specified location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location.

The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development.

Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area.

It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool.

What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets.

Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.

How do I know if a bird is breeding, wintering or migrating in my area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may query your location using the RAIL Tool and look at the range maps provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:

1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);

2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and

3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing).

Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.

What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur.

Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Facilities
National Wildlife Refuge lands
Any activity proposed on lands managed by the National Wildlife Refuge system must undergo a 'Compatibility Determination' conducted by the Refuge. Please contact the individual Refuges to discuss any questions or concerns.

There are no refuge lands at this location.

Wetlands in the National Wetlands Inventory
(NWI)
Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District.

Wetland information is not available at this time
This can happen when the National Wetlands Inventory (NWI) map service is unavailable, or for very large projects that intersect many wetland areas. Try again, or visit the NWI map to view wetlands at this location.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis.

The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems.

Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site.

Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery.

Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies.

Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.
