SUBJECT: Amendment #1 (Additional Service Request #5) Dockweiler Drive Extension Dear Carla,
The City of Santa Clarita (City) would like to redesign 13th Street from Railroad Avenue to Dockweiler Drive and Dockweiler Drive from 13th Street to Placerita Canyon Road to match the future Shadow Box offsite improvements. The improvement changes consist of the following:
• Wider 13th Street / Railroad Avenue intersection to accommodate a WB-67 vehicle and a separate bike path at grade railroad crossing
• Wider 13th Street for three (3) westbound lanes and five (5) eastbound lanes • Interim curve/future four-legged signalized 13th Street/Dockweiler Drive intersection • Dockweiler Drive with six (6) lanes between 13th Street and 12th Street • Signalized intersection at Dockweiler Drive/12th Street • Dockweiler Drive/Placerita Canyon Road intersection with revised water quality basin locations
• Dockweiler Drive transition south of Placerita Canyon Road • Dockweiler Drive Storm Drain realignment and modifications with new street alignment • Infiltration basin north of the wider 13th Street
• 2400 linear feet open concrete channel for existing pass-thru stormwater flows from 13th Street to the Railroad Avenue bridge over Little Placerita Creek These proposed improvements will be reviewed by the City at the 30%, 60%, 90%, 100% and Final phases.
The project will need to obtain new Railroad permits and approvals from CPUC and SCRRA for the 13th Street at Grade Railroad Crossing. Environmental permitting will be required for open channel outlet to Little Placerita Creek.
The City also would like to complete the Dockweiler Drive Plans, Specifications and Estimates (PS&E) and environmental permitting for the rest of the project from south of Placerita Canyon Road to the existing upper Dockweiler Drive. This segment has minor adjustments and changes.
MNS submitted the 100% PS&E package in June of 2021. Thereafter, the project was put on hold due to the impending Shadow Box and the Master’s University developments. MNS will need to address the City’s 100% comments, submit the final PS&E and address the City’s final comments.

Task 4 – Environmental Permitting
MNS team member Rincon Consultants, Inc. (Rincon) will prepare the reports and obtain the required environmental permits.
To date, Rincon has prepared the following technical reports to support the permitting effort for the project:
• Jurisdictional Delineation Report (July 2021)
• Coastal California Gnatcatcher Report (July 2021)
• Rare Plant Survey and Report (July 2021)
• Biological Resources Assessment (December 2021)
Due to several regulatory changes and the Project redesign, the Jurisdictional Delineation Report will need to be updated. In addition, the 2021 Coastal California Gnatcatcher Report and Rare Plant Survey Report will be updated with more recent data collected during the proposed 2025 survey.
Rincon also prepared the Biological Resources Assessment, which will require updates to reflect the redesign of 13th Street. To accurately reflect the re-design and meet the anticipated needs of the regulatory agencies, the text and figures outlining the project description, project footprint, and impacts to jurisdictional waters will be updated.
Additionally, the results of the Jurisdictional Delineation Report, Coastal California Gnatcatcher Survey Report, and Rare Plant Survey Report will be summarized in the Biological Resources Assessment.
Project impacts to jurisdictional waters are anticipated during the construction of the 13th Street improvements and the pedestrian bridge over Newhall Creek. Rincon will prepare the appropriate permit application packages.
Rincon proposes the following tasks:
4.1 Project Re-initiation/Management - Up to two Rincon staff will attend up to two virtual 1-hour project team meetings with MNS and the City to review the Project’s newly proposed design and project schedule. Rincon will prepare notes following the meetings and distribute them to the project team.
Rincon will be highly responsive to project management and coordination with the various parties involved to ensure all project requirements described above are met in an efficient and cost-effective manner. Rincon will provide regular communication to MNS and City staff as needed, throughout the course of the permitting process regarding project needs, changes, schedule, budget, and deliverables. This task includes miscellaneous activities required to manage the various tasks above such as regular e- mail and telephone communications and other tasks associated with contract administration and client coordination.
4.2 Technical Reports
A. Jurisdictional Delineation Report Update - Rincon will conduct a jurisdictional delineation survey of the Project area and 100-foot buffer to verify the extent/condition of aquatic resources delineated in 2021. Rincon will prepare an updated Jurisdictional Delineation Report that will reflect the survey findings and regulatory changes that have occurred since 2021, including text and figures. In addition, the previous vegetation community and land cover mapping will be verified.
Assumptions:
• A Rincon Senior Biologist and Associate Biologist will conduct the jurisdictional delineation field survey on one calendar day.
• Rincon will address one round of comments from MNS and City staff (one round total) on the report.
• The report will be included in the permit application packages. • • If the 2023 jurisdictional delineation data from Shadowbox Studios becomes available for use on this Project, a jurisdictional delineation field survey would not be required upon direction of the City. The Jurisdictional Delineation Report would then be updated utilizing the 2023 delineation data from Shadowbox Studios for the drainage at 13th Street, the 2021 delineation data from Rincon at Newhall Creek, and the text and figures would be updated to address the recent regulatory changes.
B. Protocol Coastal California Gnatcatcher Surveys and Report Update - Rincon will conduct protocol surveys for Coastal California Gnatcatcher (CAGN) and prepare an updated report. Per U.S. Fish and Wildlife (USFWS) CAGN survey protocol (USFWS
1997), Rincon will notify the appropriate USFWS office in writing, at least ten working days prior to the anticipated start date of survey work and receive approval prior to beginning work. If surveys are conducted during the breeding season (March 15 - June 30), a minimum of six (6) surveys are required, to be conducted at least one week apart.
If conducted between July 1 and March 14, a minimum of nine (9) surveys are required, to be conducted at least two weeks apart. The surveyor must hold a Recovery Permit issued by USFWS under Section 10(a)(1)(A) of the Endangered Species Act authorizing CAGN survey efforts.
After conducting the required focused surveys, Rincon will prepare a survey report for submittal to MNS and City staff for review, prior to submittal to USFWS. The survey area will include the Project disturbance area and a 100-foot buffer.
Assumptions
• Rincon will conduct nine field surveys with one biologist in areas of suitable habitat.
Each survey will be conducted by a local and permitted biologist within a 4-hour timeframe, including travel. Our estimated cost would decrease if surveys were to be conducted during the breeding season (only six surveys required). • We assume that survey results will be negative based on the 2021 negative survey results. This task does not include preparation of a Biological Assessment (BA) or other documentation addressing the presence of listed species. • Rincon will address one round of comments from MNS and City Staff and one round from USFWS staff (two rounds total) on the report.
• The report will be included in the permit application packages.
C. Protocol Rare Plant Survey and Report Update - Rincon will conduct a protocol rare plant survey and prepare an updated report. Prior to conducting the protocol rare plant field survey, Rincon will conduct a desktop review of the CDFW California Natural Diversity Database (CNDDB); USFWS Critical Habitat Portal; CDFW Special Vascular Plants, Bryophytes, and Lichens List; the CDFW State and Federally Listed Endangered, Threatened, and Rare Plants of California; and the California Native Plant Society (CNPS) online Inventory of Rare and Endangered Vascular Plants of California to determine if any additional special status plants were recorded on-site or in the Project vicinity.
A Rincon Senior Botanist and Associate Biologist will conduct one protocol rare plant field survey of the Project area and a 100-foot buffer, conducted in the appropriate season when detection of potentially occurring rare plants would be present and
flowering (spring). The survey will be conducted to determine the presence or absence of rare plants in general accordance with CDFW (2018) and CNPS (2001) survey guidelines. The survey will include an evaluation of habitat suitability to support rare plant species based on site conditions and the characteristics of rare plant species that may occur in the vicinity. A Rare Plant Survey Report will be prepared to present the results of the desktop review and field survey.
Assumptions
• A Rincon Senior Botanist and Associate Biologist will conduct one protocol rare plant field survey on one calendar day in spring (seasonally timed to allow for detection). • We assume that survey results will be negative based on the 2021 negative survey results.
• Rincon will address one round of comments from MNS Engineers and City staff (one round total) on the report.
4.3 Biological Resources Assessment
A. Biological Resources Assessment Update - In order to accurately reflect the Project redesign and meet the anticipated needs of the regulatory agencies, the existing Biological Resources Assessment will be updated so that the text and figures outlining the project description, footprint, and impacts to jurisdictional waters will reflect the redesign. Additionally, the report will be updated with the survey results and regulatory and jurisdictional updates from the Jurisdictional Delineation Report. The report will be updated with the results of the protocol surveys for Coastal California Gnatcatcher and Rare Plants. Lastly, an updated literature review will be conducted to identify and analyze the potential impacts for any newly identified sensitive species to occur on-site, and the report will be updated to provide additional or revised avoidance and minimization measures. Notably, since the preparation of the Biological Resources Assessment in 2021, the Crotch’s bumble bee (Bombus crotchii) has become a candidate species under the California Endangered Species Act and will be addressed in the updated report.
Assumptions:
• The Biological Resources Assessment will be updated to reflect a single project design (redesign).
• Any additional changes to the project design are outside of this scope of work. • No fieldwork will be necessary for this task as the fieldwork needed to inform the BRA is included in Tasks 2.1, 2.2, 2.3, and 3.2.
• Rincon will address one round of comments from MNS Engineers and City Staff and one round from CDFW staff (two rounds total) on the report. • The report will be included in the permit application packages.
B. Crotch’s Bumble Bee Habitat Assessment - Rincon will conduct an on-site assessment per CDFW guidelines (2023) of foraging, nesting, and overwintering habitat for Crotch’s bumble bee. The area assessed will include the Project disturbance area and a 100-foot buffer. At this time, Rincon does not suggest conducting a protocol-level survey for the species as it is already known to occur in the project vicinity as documented in CDFW’s CNDDB and is likely present within the Project area; impacts to underground nests can likely be avoided with sufficient avoidance and minimization measures that will be discussed in the Biological Resources Assessment, including but not limited to pre-construction surveys and avoidance of active nests if found.
Assumptions:
• Includes 4 hours of fieldwork for two Rincon Biologists combined conducted on the same day of the jurisdictional delineation survey or rare plant survey, plus 4 hours of office-based support and analysis.
4.4 Regulatory Permitting - As described above, Rincon understands that impacts to jurisdictional waters will occur as a result of construction of the 13th Street improvements, specifically an ephemeral unnamed drainage that is located in the Shadowbox property. In addition, impacts to jurisdictional waters will occur as a result of construction of the proposed pedestrian bridge over Newhall Creek. Due to the design of the bridge, no direct impacts will occur within jurisdictional waters. i.e., the channel bed, banks, and riparian; however, shading impacts to a sensitive natural community are anticipated. Rincon will prepare a California Department of Fish and Wildlife (CDFW) Lake or Streambed Alteration (LSA) Notification and a Los Angeles Regional Water Quality Control Board (RWQCB) Waste Discharge Requirement (WDR) application for the Project. A Clean Water Act Section 404 permit is not required and will not be prepared for the USACE, as waters of the U.S. are not present at the 13th Street improvements, and the waters of the U.S. in Newhall Creek will be avoided and not impacted by the construction of the pedestrian bridge.
A. CDFW Streambed Alteration Agreement - Project impacts to the CDFW- jurisdictional streambed (bed, banks, and riparian vegetation) within the ephemeral drainage near 13th Street due to the proposed construction of the stormwater conveyance system and within Newhall Creek due to the proposed shading associated
with the pedestrian bridge will require a LSA Notification pursuant to § 1600 et seq. of the California Fish and game Code (CFGC). Rincon will prepare the CDFW LSA Notification and supporting documentation, provide it to MNS and the City for review and comment, incorporate any requested changes, and upon your approval, submit the application to CDFW via their Environmental Permit Information Management System (EPIMS). Rincon will attend a pre-application meeting on-site with CDFW if requested by CDFW to discuss the Project and confirm notification requirements. Rincon will review the draft SAA issued and provide recommendations to the project team on any suggested revisions and submit the revisions to CDFW on behalf of the City.
Assumptions:
• The SAA Notification will reflect a single project design (redesign). Any additional changes to the project design are outside of this scope of work. • One senior regulatory specialist (or Project Manager) will attend one pre-application meeting onsite with CDFW staff (not to exceed 6 hours total on-site, plus travel). • Existing documentation and survey reports completed previously and as part of this scope of work will be adequate, and no additional biological surveys or reports will be needed other than what is stated herein.
• Rincon will incorporate one round of comments on the SAA Notification package from MNS and City staff (one round total).
• Rincon will incorporate one round of comments on the SAA notification package from CDFW (not to exceed 8 hours).
• The City will provide payment for application fees to CDFW directly. Rincon will calculate the final fee based on the cost of the work in the CDFW-jurisdictional streambed, which is assumed to be provided by MNS.
• The City will provide a copy of the completed CEQA document, proof of payment of CEQA filing fees, and a copy of the Notice of Determination to include in the notification.
B. RWQCB Water Discharge Requirement - Impacts to waters of the State within the ephemeral drainage near 13th Street due to the proposed construction of the stormwater conveyance system will require a WDR pursuant to the Porter-Cologne Water Quality Control Act. The Los Angeles RWQCB requires notification through submittal of a WDR application package. Rincon will prepare the WDR application package and supporting documentation, provide it to MNS and the City for review and comment, incorporate any requested changes, and upon your approval, submit the application to Los Angeles RWQCB electronically. Rincon will attend a pre-application meeting on-site with Los
Angeles RWQCB to discuss the Project and confirm permit application requirements; a pre-application meeting request will be submitted at least 30 days prior to submittal of the application to Los Angeles RWQCB. Rincon will review the draft WDR issued and provide recommendations to the project team on any suggested revisions and submit the revisions to Los Angeles RWQCB on behalf of the City.
Assumptions:
• The WDR application package will reflect a single project design (redesign). Any additional changes to the project design are outside of this scope of work. • One senior regulatory specialist (or Project Manager) will attend one pre-application meeting onsite with Los Angeles RWQCB staff (not to exceed 6 hours total on-site, plus travel).
• Existing documentation and survey reports completed previously and as part of this scope of work will be adequate, and no additional reports will be needed other than what is stated herein.
• Rincon will incorporate one round of comments on the WDR application package from MNS and City staff (one round total).
• Rincon will incorporate one round of comments on the WDR application package from Los Angeles RWQCB (not to exceed 8 hours).
• The City will provide payment for application fees to Los Angeles RWQCB directly.
The final fee is calculated based on the impacted acreage of waters of the State. • The City will provide a copy of the completed CEQA document, proof of payment of CEQA filing fees, and a copy of the Notice of Determination to include in the application.
C. Compensatory Mitigation Planning - Based on the results of the jurisdictional delineation and associated impact analysis, Rincon will facilitate purchasing mitigation credits at Petersen Ranch Mitigation Bank to meet expected CDFW and Los Angeles RWQCB requirements for permanent impacts to jurisdictional waters as a result of the Project. Compensatory mitigation for permanent impacts is a required element of the permit packages. Payment of a fee to the bank is dependent on the acreage and type of mitigation credit needed, which Rincon assumes that the City will pay directly.
Assumptions:
• Facilitation with Petersen Ranch Mitigation Bank will not exceed 10 hours, to be conducted by Rincon Senior Staff.
• The City will provide payment to Petersen Ranch Mitigation Bank directly. The final fee is calculated based on the impacted acreage and type of mitigation credit needed.
Deliverables:
• Jurisdictional Delineation Report Update
• Protocol Coastal California Gnatcatcher Surveys and Report Update • Protocol Rare Plant Survey and Report Update Compensatory Mitigation Plan • Biological Resources Assessment Update
• Crotch's Bumble Bee Habitat Assessment
• CDFW Streambed Alteration Agreement
• RWQCB Waste Discharge Requirement
