Fiscal Impact Funding for the Westside Road Bridge over Canyon Hollow Creek Replacement Project (Project) is from the Highway Bridge Program (HBP) at 88.53 percent, while the remaining funds, 11.47 percent, will be matched with City or Redding (City) Traffic Impact Fees (TIF). An additional $2,633,760 in HBP grant funds have been allocated to the City for the Project. However, no additional TIF funds need to be allocated at this time. These additional grant funds will allow staff to complete the project design and advertise for construction. Previously allocated HBP funds in the amount of $1,447,470 were insufficient to complete the project. The total bridge project (including design, environmental, right-of-way, and construction) is estimated to be approximately $4,651,446, with $4,081,231 funded by the HBP program and the remaining $570,215 coming from Citywide TIF. Alternative Action The City Council (Council) may choose not to accept the additional grant funding. In this case, the City would lose $2,633,760 in grant funding for the project and additional City funds would need to be used to complete the project. Alternatively, the Council could choose not to proceed with the project and the City would need to reimburse the California Department of Transportation (Caltrans) for costs incurred to date. Report to Redding City Council March 11, 2024 Re: 4.11(b) --Accept Grant Funds and Adopt Budget Resolution Page 2 Background/Analysis On August 5, 2015, the Council appropriated HBP funds in the amount of $1,270,410 to hire a consultant to support staff in the preparation of design and construction documents for the project. In addition, $177,060 in HBP funds were previously appropriated on March 6, 2012 for the initial request for the proposal process and project scoping. As the project has proceeded through the various stages of design, environmental review, and right-of-way, the estimates and plans have become more refined and detailed. Staff submitted the required documentation to Caltrans, the agency that administers the HBP Program, to request additional HBP funds to fully fund the project. On January 4, 2024, Caltrans approved the City's request. Construction for the bridge is anticipated to begin in Summer 2024 and continue through Fall 2025. Environmental Review This action, accepting additional grant funding, is not a project as defined under the California Environmental Quality Act. On June 16, 2020, the Council approved the Mitigated Negative Declaration and Mitigation Monitoring Program, and approved the Project. No further action is required. Council Priority/City Manager Goals This agenda item is a routine operational item.

Report to Redding City Council June 8, 2020 Re: 4.11(b) --Eastside Road and Westside Road Bridges Replacement Project Page 2 Background/Analysis The project is located on the east side and west side of State Route 273, respectively, approximately 650 feet south of the intersection of State Route 273 and Buenaventura Boulevard. The project will replace the existing Eastside Road Bridge with a new two-lane, two span cast -in-place reinforced concrete slab -bridge. The proposed structure will provide two 12 foot travel lanes, 8 -foot shoulders, one 6 -foot wide sidewalk, and concrete barriers. Approximately 300 feet of roadway will be reconstructed at both approaches to conform to the new bridge. The Westside Road Bridge will be replaced with a new two -lanes three -span cast -in-place reinforced concrete slab -bridge.

The IS shows that the proposed project could have a significant " ��"''I ological resources, but with implementation of mitigation measures, those impacts wild°`be reduced to a level considered less than significant. The mitigation measures and conservation measures to be implemented are common practices and include, but are not limited to; biological pre -construction surveys, impact minimization, exclusionary fencing, and erosion control. Based on the conclusions made in the IS, a MND was prepared. The MND describes the project, including mitigation measures, and makes the determination that there will be no significant effect on the environment provided that the defined mitigation measures are implemented as part of the project. In addition, a MMP has been written and incorporated into the MND (CEQA Section 21081.6). The MMP will be used by City staff, contractors, agencies, and monitoring personnel during and after the project to ensure effective implementation of the adopted mitigation measures outlined in the MND. Report to Redding City Council June 8, 2020 Re: 4.11(b) --Eastside Road and Westside Road Bridges Replacement Project Page 3 The IS/MND/MMP documents were sent to the State Clearinghouse for a 30 -day public review period and distribution to pertinent state agencies. They were sent to local resource agencies, the Shasta County Clerk, and posted on the Public Works Department website. A public notice was also sent to landowners in the vicinity of the project and posted in the local newspaper. Two comment letters were received during the public comment period. Responses to the comment letters have been prepared and are attached to the final MND. The City is the lead agency for the project pursuant to CEQA. As the lead CEQA agency, the Council is authorized to adopt the MND per Redding Municipal Code Section § 18.24.070.E and state law.

ENVIRONMENTAL SETTING The Eastside and Westside Road Bridges are located on the east side and west side of State Route 273, respectively, approximately 650 feet south of the intersection of State Route 273 and Buenaventura Boulevard. The bridges are located on major urban collectors that serve various commercial businesses. Eastside Road and Westside Road are located in an urban area, are bordered by commercial and industrial. Eastside Road and Westside Road Bridges Replacement Project Page 1 May 2020 City of Redding Public Works Department, Engineering Division Mitigated Negative Declaration businesses, and are separated by the Union Pacific Railroad and State Route 273. Canyon Hollow Creek runs beneath the two bridges, from the west toward the east. FINDINGS AND DETERMINATION The City of Redding conducted an Initial Study (attached) that determined that the proposed project could have significant environmental effects on biological resources. Use of specific mitigation measures identified below will avoid or mitigate the potentially significant environmental effects identified, and the preparation of an environmental impact report will not be required. If there are substantial changes that alter the character or impacts of the proposed project, another environmental impact determination will be necessary. Prior to approval of th'P�`ct;'"the'ency may conclude, at a public hearing, that certain mitigation NV measures idee Mitigated Nowe Declaration are infeasible or undesirable. In accordance with CEQA See�7 715074.1, the lead ag r may delete those mitigation measures and substitute other measures that 1t termines are equtvalore effective. The lead agency would adopt written findings that teasures) is equip t or more effective in mitigating or avoiding potential significant effer�and that it would not cause any potentially significant effect on the environment. 1.

Description of Project: 's Name and Address: CITY OF REDDING (I), Office (0), and (GI), General The City of Redding, in cooperation with the California Department of Transportation (Caltrans); is proposing to replace the Eastside Road Bridge (Bridge No. 06C0085) and Westside Road Bridge (Bridge No. 06CO071) over Canyon Hollow Creek with wider concrete slab bridges in the City of Redding, Shasta County, California. The Eastside and Westside Road Bridges are located on the east side and west side of State Route 273, respectively, approximately 650 feet south of the intersection of State Route 273 and Buenaventura Boulevard. The bridges are located on major urban collectors that serve various commercial businesses as well as residents and visitors to the area (Figure 1. Project Vicinity; Figure 2. Project Location). Page 1 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study The purpose of the project is to provide crossings over Canyon. Hollow Creek that can withstand modern traffic loading demands and meet modern safety standards. Constructed in the 1950s, both of the existing Canyon Hollow Creek bridges have deficient structure widths that match neither the roadway shoulder or sidewalk widths on the approach roadways. As a result, they have both been listed as functionally obsolete. The proposed Project will replace the existing bridges with structures that meet current state and federal bridge standards. The Project will replace the existing Eastside Road Bridge with a new two-lane two -span bridge. The proposed bridge will be a cast -in-place, reinforced concrete slab bridge. The proposed structure will provide two 12 -foot travel lanes, 8 -foot shoulders, and concrete barriers. A 6 -foot wide sidewalk will be constructed on the east side of the bridge to accommodate pedestrian traffic and the new bridge wil of 48'-11" between edges of deck. The overall superstructure depth is F-5"", 63 feet. The longer replacement bridge will decrease the restriction In sI annel at the brin` eland!Omwill provide a smoother transition between the wide upstream c�'1 and thenarrow chdownstream. The soffit elevation of the proposed bridge cq It; will be rail approximately two ��' to pass the 100 -year flood event with no freeboard. Approxrrntj 300 feet of road will' reconstructed at both approaches to raise the road to the higher bride' evation and conform to the new bridge width. Construction will be staged over two construction} s to allow a single lane of alternating traffic controlled by temporary signals. In addition to the repl`ae}gent oE� =Eastside =Pp j f J EI%IF.'

The PG&E gas line relocations and AT&T underground will require trench �exd�lion depths up to approximately 12 feet deep, and approximately 20 to 25 feet downstream or upstream of the proposed bridge. The proposed method of relocation would be open trenching with excavators or other similar excavation equipment. The in -channel work area extends approximately 25 -feet upstream and downstream of the new bridges to allow access into the channel during construction and underground utility relocations. Page 2 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study Additional Project work includes extending the sidewalk along some approaches, storm drain. modification, paving, striping, and sign installation. Two staging areas are proposed for the Project. The first staging area is within in a disturbed dirt area located at the northeast quadrant of the Eastside Road Bridge. The second staging area is a paved section of abandoned roadway located 130 -feet north of the Westside Road Bridge. Roadway and structure improvements fall within City and private right-of-way. It is anticipated the Project will require sliver strips of right-of-way to be acquired for the proposed bridge replacements, and an encroachment permit will be obtained from Caltrans for construction access (Figure 3. Project Features).

Surrounding Land Uses and Setting: Initial Study The majority of the Project area is comprised of highly urbanized, industrial land uses including Pacific Supply building materials storage yard, Redding Lumber Transport storage yard, and Fife Metal Fabricating storage yard. Adjacent land uses include commercial uses including Redding Veterinary Clinic, River City Auto, and American Appliance. Canyon Hollow Creek flows through the Project area in a west to east orientation and confluences with the Sacramento River approximately 0.56 -mile east of the Project area. The Union Pacific Railroad (UPRR) train tracks also run through the Project area in a north/south orientation. This area of Canyon Hollow Creek corridor to the east of Eastside Road is zoned as Open Space. The elevation within the Project area is approximately 495 feet above mean sea level. The City of Redding has annual temperatures ranging from a,es Fahrenheit to a low of 49 degrees Fahrenheit. The average annual rainfall is 3`fhes, and't `'p` faphy within the Project area is flat. l=.. 10.

The ms s roject is �n the of Redding, Shasta County, which is at the northern end't `the gigenN--,,—,- 1 nto V 4 Air Basin (NSVAB). The NSVAB is bounded on the north and west by by Mouz�ii Range and on the east by the southern portion of the Cascade Mountain Range and the ethe Sierra i fSO{Sl ��” �€ t,, Nevada range. These mountain ranges form a substantial phy� bar t '�,j tally created pollution as well as that transported northward on prevaihn�`� ��F in the Sacramento metropolitan area. In 1994, the air districts in the Northern Sacramento Valley Planning Area (NSVPA), which includes the SCAQMD jurisdiction, prepared an Air Quality Attainment Plan for ozone. This plan was updated in 1997; 2000; 2003; 2006, 2009, 2012, and again in 2015. Like the preceding plans, the 2015 plan focuses on the adoption and implementation of control measures for stationary sources, area -wide sources, indirect sources, and public information and education programs. The 2015 plan also addresses the effect that pollutant transport has on the NSVPA's ability to meet and attain the state standards. The Air Quality Attainment Plan provides local guidance for air basins to achieve attainment of ambient air quality standards. Areas that meet ambient air quality standards are classified as attainment areas, while areas that do not meet these Page 16 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study standards are classified as nonattaimment areas. Areas for which there is insufficient data available are designated unclassified. The attainment status for the Shasta County portion of the NSVAB is included in the table below.

California standards for ozone, carbon monoxide (except8-hourLake Tahoe), sulfur dioxide (1 and 24 hour) nitrogen dioxide, and particulate matter (PM10, PM2.5, and visibility reducing particles), are values that are not to be exceeded. All others are not to be equaled or exceeded. California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations. 2. National standards (other than ozone, particulate matter, and those based on annual arithmetic mean) are not to be exceeded more than once a year. The ozone standard is attained when the fourth highest 8 -hour concentration measured at each site in a year, averaged over three years, is equal to or less than the standard. For PMI 0, the 24 hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 µg/m3 is equal to or less than one. For PM2.5, the 24 hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard. Contact the U.S. EPA for further clarification and current national policies. 3. Concentration expressed first in units in which it was promulgated. Equivalent units given in parentheses are based upon a reference temperature of 25°C and a reference pressure of 760 torr.

Construction activities are anticipated to involve the operation of diesel -powered equipment. In 1998, the CARB identified diesel exhaust as a Toxic Air Contaminant (TAC). Cancer health risks associated with exposures to diesel exhaust typically are associated with chronic exposure; in which a 70 -year exposure period often is assumed. Although elevated cancer rates can result from exposure periods of less than 70 years, acute exposure (i.e., exposure periods of 2 to 3 years) to diesel exhaust typically are not anticipated to result in an increased health risk because acute exposure typically does not result in exposure concentrations that would represent a health risk. Health impacts associated with exposure to diesel exhaust from Project construction are anticipated to be less than significant because construction activities are expected to occur well below the 70 year exposure od used in health risk assessments. Additionally, emissions would be short- term an �' YY''l nature� and therefore would not generate TAC emissions at high enou, sure ce r tions to represent a health hazard. Therefore, overall exposure of se{`treceptors to slal pollutant concentrations from the proposed Project would bl'YYYs than significant itigation is required. d) Than Significant Imotet.

Discussion The analysis of biological resources presented in this section is based on the Natural Environment Study, Biological. Assessment, and Aquatic Resources Delineation prepared for the Project (Dokken Engineering). a) Less Than Significant with Mitigation Incorporated. Special Status Plant Species Prior to field surveys, a list of regional special status plant species with potential to occur within the Project vicinity was compiled from database searches. After a comparison of habitat Page 22 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study requirements and available habitat in the biological study area (BSA), one special status plant was determined to have a low to moderate potential to occur: silky cryptantha (Cryptantha crinita). Silky cryptantba is not listed as a federal or state protected species, but is listed in the CNPS Inventory of Rare and Endangered Plants on list 113.2. Silky cryptantha is an annual herb inhabiting gravelly streambeds within cismontane woodland, lower montane coniferous forest, riparian forest, riparian woodland, and valley/foothill grassland. The blooming period for the species is April — May and is typically found at an elevation range of 200 — 3,986 feet. Based on the presence of potentially suitable habitat; the species is considered to have a low to moderate potential to occur within the BSA. Field surveys conducted on November 30, 2017 included a habitat assessment, and focused surveys for special -status plant species. During the survey no silky cry_,tantha was observed; however, the survey was not conducted during the species bloo Constt�Ir activities (e.g:r'tding cut and fill) could affect local populations or individuals if they ,��resent. Potential dirffects include injury, mortality, and permanent loss of habitat res u(, from Project construfn. Indirect effects could occur if construction activities result in ation of habitat or wtt duality due to erosion and sedimentation, accidental fuel leaks, anOls. Standard consti n measures and BMPs HAZ-1 through HAZ-5 (included in SecfX, Hazards and Hazardous Materials) and BIO -1 through BIO -3 are included for all proieuirmg eahwork, equipment use, and work near stream channels. These BMPs limit � the poten�rf��n, sedgy tort, and spills, as well as prevent work from occurring inundestgnallrars tij ?ftr7`y'ut'' 4yfr BIO -l. As required bYt City of Retormwater Quality Management and Discharge Control Ordinance, a S��water Polluft ""W revention Plan (SWPPP) will be prepared to address BMPs that will to p' erosicrp sediment loss within the Project site. ytr4, rr S tiffs � t� � i t 4yr„�,5,�i BMPs such as silt fence, rriar seeder, t�``t battles will be placed where needed to prevent sediment from leaving the site rdg# and after`istruction. 13I0-2.

With incorporation of mitigation measure MM -1, the Project's impact on silky cryptantha would be less than significant. Special Status Wildlife Species Four special status wildlife species have a low to moderate potential to occur within the BSA: • Central Valley spring -run Chinook salmon (Oncorhynchus tshawystscha pop. 6) • Sacramento River winter -run Chinook salmon (Oncorhynchus tshawystscha pop. 7) • Central Valley steelhead (Oncorhynchus rnykiss irideus) • Western red bat (Lasiurus blossevilli) Page 23 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study The proposed Project has the potential to cause take of special -status anadromous salmonids if itresults in any one of the following: direct mortality; temporary impacts on habitats such that special -status species suffer from injury, lowered reproductive success, increased stress, lessened fitness, or mortality; permanent loss of habitat critical to a special -status fish species; or a substantial reduction in the quantity or value of fish habitat in which a special -status population occurs. However; NMFS recently issued a letter (WCRO-2019-03759) in response to Caltrans' request to initiate informal consultation. The letter states that NMFS' determined that with the use of BMPs and avoidance/mitigation measures the Project would not be likely to adversely affect Central Valley spring -run ESU Chinook salmon, Sacramento River winter -run Chinook salmon, and Cqtral Valley steelhead.

Page 24 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study Western Red Bat The nearest recent occurrence of the species is approximately 7.5 miles from the BSA, within the Whiskeytown National Recreation Area. The species is considered to have a low to moderate potential to occur within the BSA. Western red bats may roost individually or in small groups in the riparian trees. If a tree is removed that contains a western red bat nursery colony, the removal could result in mortality or injury of individuals. Indirect impacts may occur from construction disturbance if a bat with pups is present in or adjacent to the study area. Significant noise disturbance could result in mothers temporarily or permanently leaving their pups.

The natural communities of special concern within the BSA are Riverine (Canyon Hollow Creek) and Valley Foothill Riparian (the associated riparian habitat of Canyon. Hollow Creek). Riparian The BSA contains 0.49 acre of riparian habitat (valley foothill riparian). In addition to providing habitat for many wildlife species, riparian areas may provide shade; nutrient or chemical Page 25 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study regulation, stream bank stability, and input for large woody debris or organic matter to the channel, which are necessary habitat elements for fish and other aquatic species. Eastside Road Bridge: The valley foothill riparian community is not well developed on the upstream (west) side of the bridge as the Union Pacific Railroad (UPRR) tracks run parallel to the bridge and UPRR removes all vegetation within their right of way for safety purposes. This riparian area is composed of herbaceous plants and sapling tree species. The valley foothill riparian community is more developed on the downstream (east) side of the bridge and occurs as a dense narrow strip on each side of Canyon Hollow Creek. Westside Road Bradge the valley foothill riparian community is not well developed on the upstream (west)„,,, rie as this area is bordered by an industrial area and Westside ,. i it l f �i k{1 Road The ri�`'vegetatiori ; City of Redding Public Works Department, Engineering Division Initial Study anticipated to revegetate naturally; therefore, the Project impact on riparian vegetation would be less than significant. Standard conservation measures and BMPs HAZ-1 through HAZ-5 and BI0-1 through BI0-5 will be used during construction. Riverine A jurisdictional delineation was conducted on November 30th, 2017 to identify jurisdictional waters of the U.S. and State within the BSA. The results of this delineation were used to determine potential temporary and permanent impacts to identified water features, Canyon Hollow Creek is the only hydrological feature within the BSA. The creek is an intermittent tributary water of the Sacramento River, flowing west to east through the BSA. Delineation results found that approximately 0.61 acres of Canyon Hollow Creek are within the BSA.

The Canyon Hollow Creek corridor may serve as an east -west movement corridor for aquatic and terrestrial wildlife through a heavily developed portion of the City. Although wildlife may avoid the active construction area, the Project would not permanently interfere with the movement of native wildlife. Construction will be short in duration and would occur when fish have no potential to be present. The Project is not anticipated to have any lasting effects to the habitat connectivity for birds; fish, or wildlife.

Discussion a,c,d) No Impact. The Project would not expose people or structures to potential substantial adverse effects, including risk of loss, injury, or death involving rupture of a known fault, strong seismic ground shaking, seismic -related ground failure, or landslides. The Project is not located within an Alquist Priolo Earthquake Fault Zone. The nearest seismic sources are the Hoadley Fault, a Page 33 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study pre -quaternary fault (older than 1.6 million years) approximately 4.5 miles west of the Project site, Bear Creek Fault, also a pre -quaternary fault approximately I I miles southeast of the Project site, and Battle Creek Fault, a quaternary fault (age undifferentiated), approximately 14 miles south of the Project site. Landslides usually occur in locations with steep slopes and unstable soils. According to the California Department ofConservation (CDC) California Geological Survey Seismic Hazards Zonation Program (CDC 2020) the Project area is not within a known area of landslide concern. The majority of the Project area is situated on flan or very gently sloping topography where the potential for slope failure is low. The Project would also have no impact related to seismic -related failure, including liquef _tion, because the potential is believed to be slight at this predominantly flat, low-seismttt�''��tgnd construction in accordance with Caltrans' seismic design criteria will e,na; tliat substait t ; { npacts due to seismic forces and displacements are avoided "alor mimmizs'tthe extent feasibl��t�ie Project is not on a geologic unit or soil that is unstable or that W' ,WO become unstable a ;J ,'result of the Project.

On January 26, 2009, it was announced that decision regarding the denial of California's waiver. On May 18; 20+ the enactment of a 35.5 mpg fuel economy standard for automobiles a 2009 EPA granted California the waiver. The granting „ the w ;r 20, nd efforts to overturn rot in Agency, 9th Cir. Jul. le$A would reconsider their #tfttcks. On June 30, 4t allowed California to implement even stronger standards. In 2013 CARB adopted iI`regulation for GHG emissions, establishing GHG emission limits on truck and engine manufacturers that harmonizes with the EPA rule. In 2016, the EPA and the National Highway Traffic Safety Administration (NHTSA), adopted federal Phase 2 standards that built on the Phase I standards to achieve additional GHG reductions. California aligned with these federal Phase 2 standards in 2018. On June 1 2005, Governor Arnold Schwarzenegger signed Executive Order 5-3-05. The goal of this Executive Order is to reduce California's GHG emissions to: 1) 2000 levels by 2010, 2)1990 levels by the 2020 and 3) 80 percent below the 1990 levels by the year 2050. In 2006, this goal was further reinforced with the passage of Assembly Bill 32 (AB 32), the Global Warming Solutions Act of 2006. Page 36 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study AB 32 sets the same overall GHG emissions reduction goals while further mandating that CARB create a plan, which includes market mechanisms, and implement rules to achieve "real, quantifiable, cost- effective reductions of greenhouse gases." Executive Order 5-20-06 further directs state agencies to begin implementing AB 32, including the recommendations made by the state's Climate Action Team. With Executive Order 5-01-07, Governor Schwarzenegger set forth the low carbon fuel standard for California. Under this executive order, the carbon intensity of California's transportation fuels is to be reduced by at least 10 percent by 2020. Climate change and GHG reduction is also a concern at the federal level; however, at this time, no legislation or regulations have been enacted specifically addressing GHG emissions reductions and climate change California in conjunction with several environmental organizations and several other states, sued to fore �t�f�Iii, ulate GHG as a pollutant under the Clean Air Act (Massachusetts vs. [EPA] et alj,497 The court ruled that GHG does fit within the Clean Air Act's definition of Jlutant, and than t�j SPA does have the authority to regulate GHG. Despite the Supreme C'uling, there are no�iulgated federal regulations to date limiting GHG emissions.

In assessing cumulative impacts, it must be determined if a project's incremental effect is "cumulatively considerable." See CEQA Guidelines sections 15064(i)(1) and 15130. To gather sufficient information on a global scale of all past, current, and future projects in order to make this determination is a difficult if not impossible task. As part of its supporting documentation for the Draft Climate Change Scoping Plan, CARB recently released an updated version of the GHG inventory for California (June 26, 2008). Page 37 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study a) Less Than Significant Impact. GHG emissions for transportation projects can be divided into those produced during construction and those produced during operations. For the Project, construction GHG emissions would include emissions produced by onsite construction equipment. As discussed in Section 3, "Air Quality", construction emission would be below threshold's established by CARB, as well as the City's air quality threshold, and would be further reduced through implementation of 13MPs AQ -1. GHG emissions produced during operations are those that result from potentially increased traffic volumes or changes in automobile speeds. The proposed Project will replace the existing Eastside Road and Westside Road bridges with structures that meet current state and federal bridge standards. The Project would not be capacity increasing and the Project would not increase the number of auto tTic system; therefore, no impact to greenhouse gas emissions or N climate chan;t fro rations. The proposed Project contribution to global climate change I sions sidered less than significant. b) No ImpImplementation of Project would not conflict with or obstruct imple "ion of any applicable pti&i, policy or regulation adopted for the purpose of reducing the emissttsof greenhouse gases. As noted in discussion "a" above, and in Section 3, the Project is in ity's air qua_Jity policies and thresholds, and consistent with County and state i lati( the Project would have no impact. #11 —7, NrA Documentation • City of Redding. 2000.

Temporary signage would be used to alert motorists and non - motorized travelers to any Project detour, decreased speeds, uneven pavement, etc. throughout the Project alignment and controlled through -traffic would be allowed to pass during construction_ Emergency response vehicles would be given priority access through the Project site. Operation of the completed Project would have no impact on traffic operations. The Project would have a less -than -significant impact on emergency response and evacuation plans during construction. g) Less Than Significant Impact. The use of construction equipment in and around vegetated areas increases the potential for wildfire ignition. Operation of the Project would not increase the existing wildfire potenti_l, however, the standard specifications require internal combustion t engines to be equt�t��4lperational spark arrester, or the engine must be equipped for the �5 prevention of#rile potenti`t wildfire ignition would be less than significant. • 1J https /� SWRCIM5 ��trz • January 25 Mitigation None necessary. 2020.

Discussion a) Less Than Signipcant Impact. The Project will disturb greater than one acre, therefore a Construction Storm Water General Permit (CGP) is required to address storm water runoff. The permit will address clearing, grading, grubbing, and disturbances to the ground, such as stockpiling, or excavation. The permit also requires the Cite and the Contractor to prepare and Page 43 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study implement SWPPP with the intent of keeping all products of erosion from moving off site into receiving waters. The SWPPP includes BMPs to prevent construction pollutants from entering storm water runoff, The Project would not involve any discharges of waste material into ground or surface waters and would be subject to the terms and conditions included in permit authorizations anticipated to be required from the Central Valley RWQCB, CDFW, and the Corps. In addition to the CGP, SWPPP, and City Construction Standards, these permits will condition the Project to implement measures that will prevent degradation of water quality. In addition, construction and operation of the Project would not violate any water quality standards or waste discharge requirements established by the Central Valley RWQCB in its Basin Plan for the Sacramento River and San Joaquin River Basins. b) Less Than Sign The Project would not directly or indirectly result in the construction cl�',�,.<tiat woul`d�,`;` �tl�ze groundwater supplies.

To support adherence with federal, state, and local regulations/ policies conservation measures 1310-1 through BIO -5 and HAZ-1 through HAZ-5 have been incorporated into the Project. d) Less Than Significant Impact. A portion of the Project area is located within a -Zone AE of the FEMA Special Flood Hazard Area; however, replacement of the Eastside Road Bridge would remove an existing pier within Canyon Hollow Creek, increasing flood capacity. The new bridges Page 44 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study would be constructed to adequately pass flows associated with a 100-yearstorm event, and would not increase risk in release of pollutants due to Project inundation. The threat of tsunami wave is not applicable to inland communities such as Redding. Seiches could potentially be generated in either Shasta or Whiskeytown Lakes during an earthquake; however, as identified in the Health and Safety Element of the General Pian, if a seiche over 65 feet in height were to overtop Shasta Dam, or in the event of dam failure, the proposed Project area would be outside of the inundation zone. e) No Impact. Construction and operation of the Project would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan.

Construction noise during this Project would be intermittent; and noise levels would vary depending on the type of construction activity. The lowest construction equipment -related noise levels would be 55 dBA at a distance of 50 feet for sound from a pick-up truck. The highest noise levels for this Project are anticipated to be up to 101 dBA at a distance of 50 feet for an impact pile driver. Noise volumes at the closest residence approximately 550 feet from the impact pile driver are anticipated to temporarily experience Page 48 Eastside Road and Westside Road Bridges Replacement Project May 2020 City of Redding Public Works Department, Engineering Division Initial Study noise volumes at approximately 80 dBA, which is lower than the existing ambient 88 dBA freight train noise. While the impact pile driver will be the dominant noise source during construction, it will be intermittent and temporary, and received at a volume lower than other existing intermittent ambient noise.
