Project Understanding and Approach Project Need: The City of La Quinta, in cooperation with California Department of Transportation (Caltrans), proposes to replace the existing Avenue 50 Low -Water Crossing (LWC) (i.e., an at -grade road across the channel bed) with a new "all- weather" Bridge over the La Quinta Evacuation Channel (City Project No. 2019-02) (herein referred to as the Project). Avenue 50 must be closed periodically due to flooding following heavy storms, thus cutting off access to a nearby school and blocking one of the City's major east -west arteries. The Project is funded by Federal Highway Bridge Program (HBP) administrated by Caltrans Local Program. HBP will reimburse 80% of the project cost while the remaining 20% Local Match of the cost will be from the City and/or CVAG Measure "A" local funds. CVAG Measure "A" funds, if used, participate 75% of the Local Match. The Project will construct a 4 -lane bridge with enhancement in traffic capacity from the existing 3 -lane LWC. Additional roadway improvement features include ADA -compliant sidewalks, shoulders, and a pained median. The new bridge is intended to provide an ultimate geometric cross section per the City's General Plan. The structure will be construed in stages to maintain access to existing traffic, pedestrians, and bicyclists. The Project includes channel invert grading, channel slope protection, and the relocation or adjustment of existing utilities. Existing Roadway Conditions: Please refer to Exhibit C-1 for the following technical discussion. General - Avenue 50 in an east -west direction is classified in the City's General Plan as a Primary Arterial with a 108' Right of Way, a 16' raised median, 8' shoulders, and one I V and one 12' lane in each direction with 6' sidewalks behind the curbs. Th project site is within the City's Image Corridor. The 8 -foot -wide shoulder is considered a Class II Bike Lane per the General Plan and Avenue 50 in is this area is not designated as a Golf Cart Trail. Avenue 50 is posted for 50 mph. Horizontal - East and west of the project, Avenue 50 consists of two lanes in each direction with a raised median. The street reduces to one westbound lane and two eastbound lanes through the channel and a continuous sidewalk on the north side. At Washington Street on the west end of the project area, Avenue 50 is striped for one westbound through lane and two dual left - turn lanes. It is believed that the reason for the short dual left -turn lanes is due to the limited room within the roadway taper to provide one long left -turn lane. Vertical - Starting from Washington Street and going east, Avenue 50 rises and has a crest vertical curve with the highpoint approximately 300 feet from Washington Street. Based on Caltrans HDM the curve is insufficient and supports a speed of 40 miles per hour. The grade reaches the elevation of the channel bottom about 900 feet east of Washington and remains flat through the existing concrete low-water crossing before rising again and cresting at 1,300 feet from Washington Street. The Avenue 50 grade then slopes downward as it goes east. Existing Sections - o West of the channel, beginning at Washington Street the curb -to -curb width is 76 - feet supporting one right turn lane, one WB through lane, two left -turn lanes, and two eastbound lanes. There is a sidewalk on the north side. o Through the channel Avenue 50 transitions to two eastbound lanes and one westbound lane and sidewalk on the north side. The sidewalk is on the concrete - surface of the LWC. o East of the channel Avenue 50 resumes to 76 feet from curb -to -curb with a 12' raised median, curb and gutter and 6' sidewalk on both sides. Existing Right of Way — The existing City right of way between the crest vertical curves east and west of the channel is 60 feet wide. CVWD owns the right of way in the triangular areas of the channel grading as well as the swath along the Channel. Available information shows that a portion of the Elementary School property extends beyond its fence along the back of sidewalk. Also, the Homeowner Association of the development in the southeast quadrant of the project has a property line behind the existing back of walk. Existing Utilities — Based on field reconnaissance and review of available documents, the following observations are made: o IID Transmission — Crosses Avenue 50 west of the channel, then proceeds easterly along the north top of slope. The transmission pole east of the channel is located within the vertical depression of Avenue 50. o IID Distribution — Overhead on the northwest quadrant of the project beyond the top of slope. It joins the Transmissions poles and continues east. o CVWD Sewer — Sewer lines in Avenue 50 flow east to the channel. The sewer line flows south westerly in the channel. The sewer systems converge in the channel north of Avenue 50 and pumped in an 18" force main easterly along Avenue 50. The pump station is on the top of the northeast berm of the channel. o Sothern Cal Gas — 3" gas line passes through the south side of Avenue 50. o CVWD Water — an 18" waterline passes along Avenue 50, 23 feet north of the street centerline. Page 19 o Telephone — Frontier has an underground line along the south side of Avenue 50. o Cable TV — Spectrum is overhead on the northwest side of the channel, goes underground and crosses Avenue 50. Then this utility may share the conduit with Frontier as it goes east on the south side of Avenue 50. o Storm Drain — An 18" RCP flows from the northeast corner of Washington Street and Avenue 50 intersection and outlets into the channel approximately 65 feet north of Avenue 50 centerline. Proposed Roadway Improvements: Typical Section — A majority of the proposed curb -to -curb typical section follows the existing section east of the channel. There are two exceptions to this section. One is the introduction of Type 85 Barriers on the bridge to protect pedestrians from traffic at a posted speed limit greater than 45 MPH. This is a Caltrans mandatory design requirement. If the proposed painted median and travel lanes remain 12 feet wide, the overall bridge width will be 4 feet wider than the HBP-programed bridge width to accommodate for the two barriers. The second exception is the introduction of a Westbound right -turn lane at Washington. Assuming the right -turn improvement is not part of the Troutdale development, the traffic signal will also be improved. Avenue 50 Road Profile Improvements - The objective of the road profile is more than raising the road to allow the channel drainage to adequately flow. It is to provide travelers with a safe design with stopping sight distance consistent with the posted speed limit while minimizing the length of construction to reduce construction staging, drainage and utility impacts. The HBP funding document provided with the RFP showed a possible profile design. Based on available information including preliminary hydraulic runs, as described later in this section, a profile solution has been designed and is seen in Exhibit C-1 to demonstrate our team's understanding of the project challenges. Bridge Length - The reasoning behind exhibiting a bridge length of 180 feet is detailed elsewhere. The final length will be determined using verifiable data. However, we are aware that the existing span of the top of the downstream channel (North) of Avenue 50 is 170 feet. Bridge Height — Using the WSE and Freeboard elevations discussed elsewhere in this section, the minimum centerline elevation was established by combining the bridge deck thickness to the additional elevation due to the bridge cross slope and channel skew. Based on available topographic information, the crest curve over the channel is slightly higher than both of the existing crest curves east and west of the channel. The profile seen in Exhibit C-1 provides a straight grade from the westerly crest curve. The advantage to this design as opposed to introducing a sag curve is that the ride is smoother for travelers following the speed limit, and it is not necessary to collect the drainage east of the crest in a sump because drainage is collected on Avenue 50 east of Washington Street. Flow traveling east is collected in a slump, which protects the capacity of the existing storm drain systems east of the project. Troutdale Development — Fortunately the proposed Avenue 50 entrance to Troutdale Development is located at the existing crest vertical curve where the improvements will join existing. Therefore, assuming Troutdale is constructed first, there will be minimal impact to the driveway. Reconstruction may be limited to minor grade changes to the easterly curb return. Proximity to Residences — Raising the roadway by approximately 18 feet will make it at the same level as the house on southeast corner of the project site. By visual inspection it is uncertain if the backyard property is protected by a tubular steel fence with thick vegetation or if there is a solid block wall that will serve as a noise barrier when the bridge improvements are completed. Either way, noise and possibly privacy impacts are expected, and mitigation will be addressed in the environmental document. Channel ad Drainage: The major watercourse located within the project reach is the La Quinta Evacuation Channel (LQEC). The channel serves as a flood control system for a sizable drainage area of the City of La Quinta including Bear Creek and the Oleander Basin. The segment of the LQEC located upstream and downstream of Avenue 50 is an earthen channel and it is confined in a well- defined channel configuration through the project site. The width of the channel through the project site, measured perpendicular to the general flow path, is approximately 170 feet. The depth varies but it is typically about 12 feet. The gradient of the channel near the Avenue 50 LWC is relatively flat, approximately 0.0003. The LQEC upstream of Avenue 50 under Washington Street consists of a concrete lined trapezoidal channel with a bottom width of 50 feet, depth of 16.5 feet and sides lopes of 1.5:1. The Coachella Valley Water District (CVWD) operates and maintains the channel reach of the LQEC. The peak Standard Project Flood (SPF) for the LQEC is 7,600 CFS. Based on the Flood Frequency Curve (FFC) for Whitewater River and using the ratio between the SPF and the 100 -year flow, it is estimated that the Q100 is approximately 4,100 CFS. CVWD's Ordinance 1234.2 that was adopted in 2017 states that all its regional and tributary flood control channels will be designed based on the 100 -year Plus Design Standard. This standard requires that flood control channels will be sized to convey the tributary Q100 with a minimum freeboard of 3 feet. An additional freeboard of 1 -foot might be required at bridge crossings. Page 1 10 Review of the flood plain map published by FEMA reveals that the existing LQEC appears to have the capacity to convey the 100 -year flow rate (i.e., the floodplain is contained within the limits of the existing channel). The flood hazard designation is shown as Zone "A", a 100 -year flood hazard area with "no base flood elevation determined". Channel and Drainage Project Approach The preliminary hydraulic study will focus on evaluating the impacts to the existing floodplain (or channel water surface) elevations and flow velocities of the LAEC due to the proposed roadway widening and bridge improvements. The study will also focus on the scour potential of the channel under the proposed bridge. The project team will utilize a steady-state hydraulic model (HEC -RAS computer model) to determine the preliminary channel capacities, floodplain elevations, backwater effects, and identify any deficiencies with the existing bridge/channel structures (pre -project condition or existing floodplain condition). The hydraulic model will also be utilized to determine the impacts to the surrounding improvements (i.e., golf course and existing homes) due to the proposed new bridge including changes to the natural geomorphic stream pattern (post -project condition or proposed floodplain condition). The floodplain study will be performed based upon the 100 -year flood flow with a minimum of 3 feet of freeboard. The scour study will be performed to satisfy Caltrans' and CVWD's requirements. In order to satisfy Caltrans' requirements, the appropriate equations in the HEC -18 manual will be used to estimate the magnitude of the local pier scour, local contraction scour and abutment scour components expected under design flow conditions for both the pre -project and post - project conditions. Long-term degradation of the channel will also be evaluated. To satisfy CVWD's scour requirements, a general scour for the existing and with -project conditions will be computed using the Blench Regime Equation in conjunction with the pier scour, contraction scour, and abutment scour as defined in the HEC -18 manual. The project team will review and identify the required channel improvements and scour protection required for the project. Preliminary grades and elevations will be determined, and a plan view shows the limits of improvements, identifying the work to be constructed, miscellaneous details, and typical section will be provided. Based upon our recent dealings with CVWD on maintenance access ramps for their channel, the Project Team will prepare a preliminary design for CVWD's maintenance access ramps. It is understood that CVWD already has an existing access ramp on the east side of the LQEC just north of the existing pump station. CVWD might need additional access ramps at the northwest corner and /or southwest corner of Avenue 50 and the LQEC. This task item will be shown as an optional task in the proposal. The Project Team performed an initial bridge hydraulic study in support of the existing condition and 2 bridge alternates: (1) A two -span, 130 -foot bridge measured along the current roadway alignment and a 3 -span, 180 -foot bridge. The analysis was performed based on the estimated Q100 of 4,100 CFS with 2 feet of debris on each side of the pier. It was assumed that the width of the pier column is 30 inches. Below are the results of the preliminary hydraulic analysis at the upstream end of the proposed bridge. There is not much variance between the 100 -year water surface elevations (WSE) between the 180 -foot and 130- foot bridge. Additionally, the hydraulic results from both - r' alternates are relatively close to the hydraulic results under the existing condition. This is primarily due to the flat R= gradient of the LQEC. Additionally, Mission Drive located downstream of Avenue 50 LWC acts as ag rade - 1 control structure, as it is 6 feet higher than the invert of the 3$0 -FOOT ALTERNATE 330 -FOOT ALTERNATE channel, causing a backwater effect that propagates upstream through Avenue 50 LWC. The difference is in the flow velocities. The flow velocities associated with the 130 -foot bridge are higher than the 180 -foot bridge due to the constricted opening. Both alternates also show higher flow velocities when compared to the existing condition. However, the higher flow velocities are considered inconsequential in terms of scour because they are less than 5 FPS. The Project Team will prepare a roadway and bridge deck hydrology study in support of the roadway and bridge deck drainage design using the Riverside County Flood Control District's (RCFCD) Rational Tabling method. The hydrology study will be performed based on the existing and proposed conditions. Additionally, since the roadway over the bridge will be higher than the existing roadway easterly of the bridge, a sump or low point on the roadway will result, which necessitates the construction of an underground facility and catch basin system that will drain the sump and discharge the flow into the LQEC downstream of Avenue 50. The Project Team will prepare design plans for that proposed drainage system including the underground drainage facility designated as South Alternate 1 as identified in the City of La Quinta's Focused Area Drainage Study dated 2016. That proposed facility will be constructed as a parallel system to increase the flow capacity of the existing system and Page 1 11 it will include secondary overflow inlets at the existing catch basins to provide an additional and emergency outlet for the tributary flow in the event the existing catch basins become clogged with sediment and urban trash. Stage Construction: The objective of stage construction is to keep Avenue 50 open to traffic, pedestrians, and bicyclists during construction. A minimum of one lane in each direction will be open with safe pedestrian and bicyclist access. Two strategies are possible. One strategy is to build the bridge one half at a time. The second strategy is to build the entire bridge in one stage. 1) Half/Half Bridge Construction - a. Description - One half of the bridge is constructed along remoor Marin. -PASS Ave BY - with as much of the roadway pavement, curb, gutter, and Edge of Pavement 50 sidewalk on the same side as bridge as possible. Due to the Grace "3WMM grade differential of approximately 18 feet at the bridge Needed "' , approaches, the open roadway should be offset to provide a proper horizontal clearance to a temporary shoring system that f is to be designed by the contractor. The shoring system can be _ a conventional sheet or solder piling or a wrapping MSE wall. Kfail K -hail : Temporary Shoring at Adding a K -rail, the roadway is then approximately 12 feet Approaches from the ultimate roadway centerline at the east and west end ExisGn$18' CVWID 6Natermain of the bridge. The offset will taper to zero as construction goes Proud in Place further from the bridge. Currently there is insufficient roadway STAGE 1 section to build half of the bridge and provide two 12 -foot HALFIHALF SCENARIO lanes and pedestrian access twelve feet from centerline. Approximately Eight to Ten feet of additional pavement will be needed at the channel crossing location to provide for two 12' lanes, a K -rail, and five-foot wide pedestrian and bicyclist access. For this proposal, the additional paving is being referred to as a mini -by-pass. Grading of the existing side slope will extend approximately 700 feet to the west and 350 feet to the east. Approximately 300 feet of existing curb, gutter, and sidewalk east of the channel crossing will need to be removed. Further studies will determine which side should be built first. b. Half/Half Bridge Construction Pro's and Con's Pro's - Mini -By -Pass is for a short duration. Traffic is back on the roadway beginning in Stage 2. Staging provides an opportunity for utilities to relocate without disrupting service. Con's - Two stage construction costs more than One Stage and takes longer to construct. 2) One Stage Bridge Construction a. Description — The entire bridge is built in one stage as well as most of the roadway improvements and one side of the channel improvements. Like the Half/Half Bridge Construction above, traffic is reduced to 40 miles per hour, and the offset of traffic follows reverse curves with a minimum radius of 650 feet with a short tangent. Temporary shoring walls will be installed to reduce the offset of the bypass from the end of the bridge and keep it inside existing CVWD right of way. b. One Stage Bridge Construction Pro's and Con's Pro's — Construction time is shorter, and cost less than Two -Stage construction. Con's — This strategy may cause too much right of way TCE or grading impact to be feasible. More development topography and right of way information is needed to confirm. This strategy does not accommodate the staged relocation of utilities. The preferred strategy will be determined during the development of Conceptual Stage Construction Plans. The selected strategy will be based on construction timing, overall construction costs, and impacts on the surrounding area and the relocation of existing utilities. Utility Relocation: Coordination with utility companies will confirm the location of existing utilities, which will play an important role in developing the bridge construction strategy. The key objective is to keep existing services operating during construction. Relocation of major utilities is described in the Construction Staging section below. Due to the proposed profile change, all underground utilities crossing the channel are affected. Based on our understanding of provided information and a site visit, the following is anticipated. o Existing utilities such as So Cal Gas, Frontier, and Spectrum can be relocated inside the bridge cells. o CVWD's 18" Watermain will need to be relocated. The diameter is too large to be located in the bridge. There are three possible relocation scenarios: i. Relocate the waterline underground outside of the bridge footprint prior to the construction of the bridge. The bridge can be built in one or two stages. ii. Protect the line in place during Stage One while the south half of the bridge is under construction. Relocate the waterline beneath the soffit of the south half of the bridge before beginning construction of Stage Two. The bridge profile will be raised by one extra foot to maintain the freeboard. Service disruption is minimal. Page 1 12 iii. Protect the line in place during Stage One while the south half of the bridge is under construction. Then shut down the waterline while Stage Two is under construction. Upon the completion of the bridge, relocate the waterline beneath the closure pour slab. This scenario only works if CVWD will permit a long-time closure of the waterline. o A portion of CVWD's 21" Sewer Force Main will conflict with the west bridge abutment. It is anticipated that a segment between two existing manholes can be realigned by introducing a manhole to create angle points. o The CVWD Sewer Force Main pump station and other sewer facilities immediately north of Avenue 50 can be protected in place. o IID Transmission Poles are not raised to grade but are instead replaced by poles installed next the existing poles. The pole next to the elementary school is replaced by a pole with its base approximately 6 feet higher than the existing pole. Avenue 50 is being raised approximately 18 feet at the location where the transmission lines cross west of the channel. Further study and coordination with IID will determine the extent the poles or lines need to be raised. o IID Distribution on the north side of Avenue 50, west of the channel, appears to be far enough from the proposed improvements to be protected in place. Bridge Alternatives: Superstructure Alternatives - We envision two viable and competitive superstructure alternatives including the Precast Pre - Stressed (PC/PS) Voided Concrete Slab and the Cast -In -Place Pre -Stressed (CIP/PS) Concrete Voided Slab as shown in Exhibit S-1. The modern PC/PS voided concrete slab option can be erected much faster than the CIP/PS voided concrete option while the CIP/PS voided concrete slab is the more economic structure type but requiring falsework in the channel. Both structure options offer the same shallow bridge thickness to span ratio of 3% that will minimize the raise of the deck/road profile to meet hydraulic freeboard requirement for the bridge soffit. The slab voids can serve openings for relocation of the existing small utilities. Pros and cons of both superstructure alternatives will be further studied in accordance with Caltrans Bridge Type Selection process and a Type Selection Report must be prepared for the city and Caltrans' approval. The bridge design must follow Caltrans California Amendments to the AASHTO LRFD Bridge Desing Specifications. Several Caltrans bridge design and detail manuals including the Seismic Design Criteria (SDC) Manual, the latest Standard Plans, Specifications and Special Provisions must be followed. _ 4&'-8--STAGE2COKUMIJGTION _ 45'--- STAGE 1 CONSTRUCTION _ 50 1'- 6•-g_�-0�__ 12'd' 12.4r _ 12'_p" _ 12'-Q" __ 12•'8• PAINTED dQ000❑0000000000000 .0000 00000000o00000 PGM8 VOIDED CONCRETE SLAB - CI PIPS VOIDED COMCREIE SLAB POUR CIP/M VOIDED CONCRETE SLAB TYPICAL SEGTION HONG 94.4.. 49'-Q' - STAGE 2 CONSTRUCTION -ARCHITECTURAL Core ' BARRIER ARID RAILING, Typ yy�(( 30' Dia Cmc COLUMN DN 30^ CI DH TYPE 1 Cane PILE, Typ 5438'-10" - -STAGE 1 CONSTRUCTION 3'-8' C—BARRIER CLQSIIRE rYPE85,Typ- POUR PC/PS VOIDED CONCRETE SLAB TYPICAL SECTION N M] LE OKI` CAP Substructure Alternatives — Based on our preliminary geotechnical data research, the proposed bridge site is not within either Alquist-Priolo Earthquake Fault Zone or Holocene Faults. The fault rupture is considered low, however the preliminary horizontal peak ground acceleration (PGA) at the bridge site was calculated to be slightly higher than 0.6g, which dominates the selection of the substructure type. As noted in the Channel and Drainage section, the bridge length can be from 130 to 180 feet or even 200 feet (depending on the final discussion with CVWD), which will require one or two piers in the channel bed. According to the current Caltrans Seismic Design Criteria, the pier wall as shown in the HBP funding documents is a design feature that is no longer to be used for a new bridge; therefore, the multi -column pier is recommended for the substructure type. CNS reviewed the adjacent Washington Street Bridge Plans and found that the Cast -In -Drilled -Hole (CIDH) Concrete Type I Shaft may be feasible for the proposed bridge structure. Other foundation types, such as driven piles will also be considered during the Bridge Type Selection process. For a slab bridge, a short seat -type abutment on a diaphragm wall with one row of 30 -inch -diameter CIDH concrete piles is the most suitable and cost-effective abutment type. A bridge general plan, shown in Exhibit S-1, reflects the possible superstructure and substructure types of the proposed bridge as discussed above. The exhibit shows the bridge will be constructed in two stages to minimize the project footprint and avoid disrupting utility services. Other construction staging considerations are discussed in the Stage Construction Section. Caltrans Type Selection Approval - The current Caltrans Local Assistance procedures require a Virtual Bridge Type Selection meeting in the PA&ED Phase of the project for HBP-funded bridge projects. There are guidelines for the preparation Page 1 13 of the Bridge Type Selection Report that is to be submitted to Structures Local Assistance (SLA) for review. Caltrans functions units will also review the preliminary channel hydraulics report and the preliminary bridge foundation report. Increase in Vehicle -Miles-Traveled: Per the State Office of Planning and Research (OPR), "Project types that would likely lead to a measurable and substantial increase in vehicle travel generally include the addition of through lanes on existing or new highways..." Since the project increases capacity along Avenue 50 from 3 lanes to 4 lanes, the project has the potential to induce additional vehicle -miles - traveled (VMT). However, since the project improvements are included within SCAG's Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), the increase in VMT resulting from the project would not exceed the threshold established by the City for determining a significant VMT impact. Nevertheless, the project includes the addition of roadway facilities that support the expansion of alternative travel modes. We will quantify the VMT reduction potential of these elements to demonstrate that the project's VMT impact will be less than the increase identified by the RTP/SCS. In addition, the project team has extensive experience working with local agencies to identify and implement a variety of VMT reducing projects and programs. We have worked with CVAG and jurisdictions in the Coachella Valley region to establish frameworks for implementing and funding various projects which will reduce the region's VMT. Right of Way Impacts: Study of right of way documents will confirm the dimensions and alignment of the existing right of way along the entire project limits. Based on available information and a desire for 100 foot Right of Way as mentioned in the RFP, the table below summaries the anticipated estimated impacts. North Side of Avenue 50 AP Number Owner Disposition 646-070-016 Troutdale Village TCE 646-070-005 CVWD Take, Slope Easement and Right of Entry 646-070-001 Desert Sands USD Slope Easement South Side of Avenue 50 AP Number Owner Disposition 770-040-012 00217La Quinta UHC Take, TCE 770-040-001& 004 CVWD Take, Slope Easement and Right of Entry 770-070-15 & 16 Fairways HOA Slope Easements 770-070-017 Private Residence TCE if Noise Barrier is needed On the north side of Avenue 50 it is assumed that the necessary right of way fronting Troutdale Village to accommodate the proposed right turn lane will be dedicated as a condition of approval. Approximately 20 feet of right of way along Avenue 50 will be acquired from CVWD to achieve 50 half street feet wide R/W. According to available records, a portion of the Right of Way fronting the elementary school extends to the back of sidewalk. A small slope easement between the proposed back of walk and existing property fence is anticipated. On the south side of Avenue 50 a small amount of right of way is needed at the southeast corner of Washington Street. And similar to the north side, approximately 20 feet of right of way along Avenue 50 will be acquired from CVWD to achieve 100 feet wide ultimate R/W. The Right of Way along the graded east slope belongs to the Fairways Homeowners Association and will need a slope easement. There is a concern that the proximity of the residence at the corner will experience excessive noise once the bridge opens. It is possible a TCE will be needed in order to construct a noise barrier. Environmental Considerations: Dokken has reviewed the proposed project and determined that the primary environmental constraints for the construction of a new bridge and roadway in place of the existing low-water crossing are related to potential noise impacts to adjacent residents and tribal/cultural/paleontological resources. The City of La Quinta will be the lead agency under California Environmental Quality Act (CEQA). As the Project involves FHWA federal funding administered by Caltrans, Caltrans will be a lead agency under the National Environmental Protection Act (NEPA). Dokken and the environmental lead, Zach Liptak, have vast experience working in the area and with the various regulatory agencies overseeing environmental resources in the region through work on various bridge projects. Dokken's experienced in-house CEQA/NEPA experts, along with noise, biological, cultural resource, and other technical specialists, have the expertise to streamline all required environmental technical studies and the environmental document to ensure that CEQA and NEPA approval remains on schedule and within budget. Vehicle Miles Traveled - Dokken understands that the City has a Vehicle Miles Traveled Analysis Policy to comply with SB 743 under CEQA. As mentioned earlier in this section, the City's threshold of significance for transportation projects is that Page 1 14 the Project cannot result in a net increase of VMT greater than that consistent with the SCAG Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). As the Avenue 50 Bridge Project is currently included in the RTP/SCS, it is anticipated this Project would be consistent with SB 743 requirements and would not result in a significant impact under CEQA. VMT modeling will be conducted consistent with the City guidelines for disclosure purposes and for use in air quality emissions modeling, but no significant impacts or mitigation for VMT under CEQA is anticipated. Noise Impacts - The potential noise impacts associated with the replacement of the existing low-water crossing with a new bridge and widened roadway will be walls with Glass Toas documented in a Noise Study Report and summarized in the environmental document. Dokken is familiar with the Caltrans' federal noise thresholds of 67 dBA and the City's standard conditionally acceptable noise threshold of 65 dBA CNEL (Community Noise Equivalent Level) for residences. Dokken's in-house noise specialists will measure existing noise levels for nearby residents, which are considered sensitive noise receptors, to ensure the noise model accurately predicts future noise volumes as a result of the project. The noise model will predict current, future no -build, and future -build alternative noise levels using the appropriate noise predictive model, TNM 2.5. The existing soundwall along the homes in the southeast may be sufficient to abate future noise along Avenue 50 with the new widened roadway and bridge; however, this will be confirmed with TNM. If additional abatement is necessary, Dokken has utilized a variety of materials such as plexiglass and glass to maintain existing views for residents while sufficiently abating the noise. Biological Resources - Based on preliminary literature and records research, Dokken anticipates impacts to biological resources to be minimal due to the lack of suitable habitat and the existing level of disturbance in the parcels adjacent to the roadway. The La Quinta Evacuation Channel is considered a jurisdictional water as it is a realigned natural channel and will require regulatory permitting. The project is also considered a covered project under the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) and the Project will need to be consist with applicable guidelines for biological resources. For consistency with the CVMSHCP, the project is anticipated to conduct surveys for burrowing owls, nesting birds, and potential rare plants. The CVMSHCP does not identify any modeled habitat for covered species occurring within or adjacent to the Project; therefore, no impacts to CVMSHCP Modeled Habitat for Covered Species are anticipated to occur. The minimal potential for biological impacts is supported by the adjacent Troutdale Village Project which conducted biological surveys and concluded no sensitive biological resources would be impacted by the development project. Cultural and Paleontological Resources - Dokken has reviewed the Cultural Resource Investigation for the adjacent Troutdale Village Project, which found that 117 cultural resources have been recorded within one -mile of the development, including 60 prehistoric archaeological sites, two historic period archaeological sites, 40 historic period built -environment resources, one multicomponent site, 13 prehistoric isolated artifacts, and one historic period isolated find. While the low- water crossing is not located along a historic drainage, it is still considered culturally sensitive due to the large number of known resources in the area. Additionally, due to the sensitivity of the area, it is anticipated there will be substantive Native American consultation with the nearby tribes to help identify the potential for prehistoric cultural resources. The Troutdale Village Project tribal consultation efforts resulted in requiring an archaeological monitor be present to observe ground - disturbing construction activities, and likely a similar request will be made for this Project. Dokken's archaeologists have a trusted rapport with the local tribes including the Torres Martinez Desert Cahuilla Indians Cultural Committee and Pattie Garcia -Plotkin, the Tribal Historic Preservation Officer for the Agua Caliente Band of Cahuilla Indians, who will likely request to consult under Assembly Bill 52 and Section 106 on the project. Further, the City's General Plan identifies this area as having a high paleontological sensitivity due to soil unit being mapped as the Lake Cahuilla Beds and have a high potential to have fossilized plants and animals. A paleontological record search will be requested from the Natural History Museum and Western Science Center to determine if any known paleontological resources are known within the Project vicinity and the results along with any necessary avoidance, minimization, or mitigation measures will be disclosed in the CEQA IS/MND. Environmental Documentation - As no significant unavoidable impacts under CEQA are anticipated, environmental compliance under the CEQA is anticipated to be completed utilizing an Initial Study with Mitigated Negative Declaration (ISMND). As VMT has already been addressed by the City of La Quinta's Vehicle Miles Traveled Analysis Policy. Under NEPA, it is anticipated a Categorical Exclusion (CE) would be required by Caltrans, summarizing the results of the technical studies. Dokken will utilize the findings of the technical studies to prepare the necessary CEQA and NEPA documentation for public review and comment.

The Consultant will show the location of the utilities based on the record drawings provided by the utility companies and by the collection of various as -built plans and by information provided by the topographic surveys to prepare a Utility Base Map. Deliverables: Introductory Request for as-builts notices, As -Built Facility Maps, Utility Base Map in CAD. TASK 3 — PRELIMINARY 35% ENGINEERING DESIGN Page 1 18 3.1 Traffic Study KOA will conduct an operational analysis of weekday peak hour conditions at key locations within the City of La Quinta and neighboring jurisdictions. The analysis will evaluate delay and level -of -service (LOS) conditions at the study locations under existing, opening year, and buildout conditions. Traffic counts will be conducted at the study intersections as part of Task 2.1. Future year volume forecasts will be conducted using the Riverside County Transportation Model (RIVCOM) and will incorporate traffic growth associated with cumulative projects throughout the region. In addition, as the construction of the bridge will require the temporary closure of Avenue 50, east of Washington Street, the traffic study for the project will also include an analysis of detour traffic and its impact on the operation of transportation facilities surrounding the project segment. The evaluation of detour traffic will also be conducted using the RIVCOM to determine the most likely alternative routes for detour traffic. To provide a fully comprehensive evaluation of project impacts on transportation facilities, the traffic study will include an assessment of pedestrian and bicycle circulation, an analysis of historical collision data along the segment of Avenue 50, and a calculation of the Traffic Index for the new bridge pavement section. Deliverables: Traffic Study Scoping Document, Traffic Study Report 3.2 Preliminary Floodplain and Bridge Hydraulics Study ACI will perform a 50 -year, 100 -year and 200 -year floodplain and bridge hydraulic analyses based upon the existing and with -project conditions. Caltrans will require the team to perform the 50 -year bridge hydraulics to ensure that the proposed bridge will convey the 50 -year flow plus 2 feet of freeboard. Additionally, Caltrans will require that the proposed bridge is designed to pass the 100 -year flow with no freeboard. The 200 -year flows will be developed as the basis for the scour analysis as required by Caltrans. CVWD's Ordinance 1234.2 that was adopted in 2017 states that all its regional and tributary flood control channels will be designed based on the 100 -year Plus Design Standard. This standard requires that flood control channels will be sized to convey the tributary Q100 with a minimum freeboard of 3 feet. Since CVWD has a higher freeboard requirement than Caltrans requires, ACI will work with the city and Caltrans to streamline approval of the project in setting of two different design criteria. The HEC -RAS model will be developed to determine the preliminary channel capacities, floodplain elevations, backwater effects, and identify any deficiencies with the existing bridge/channel structures (pre -project condition or existing floodplain condition). The hydraulic model will also be utilized to determine the impacts to the surrounding improvements (i.e., golf course and existing homes) due to the proposed new bridge including changes to the natural geomorphic stream pattern (post - project condition or proposed floodplain condition). The floodplain study will be performed based upon the 100 -year flood flow with a minimum of 3 feet of freeboard. The scour study will be performed to satisfy Caltrans' and CVWD's requirements. In order to satisfy Caltrans' requirements, the appropriate equations in the HEC -18 manual will be used to estimate the magnitude of the local pier scour, local contraction scour and abutment scour components expected under design flow conditions for both the pre -project and post - project conditions. Long-term degradation of the channel will also be evaluated. AASHTO LRFD-BDS requires; "scour at bridge foundations to be investigated for two conditions: (1) design flood and (2) check flood. Scour for the design flood is based on the 100 -year event or from an overtopping flood of a lesser recurrence interval. Scour for the check flood is based on a higher flood discharge; typically, a 200 -year event." To satisfy CVWD's scour requirements, general scour for the existing and with -project conditions will be computed using the Blench Regime Equation in conjunction with the pier scour, contraction scour, and abutment scour as defined in the HEC - 18 manual. ACI will review and identify the required channel improvements and scour protection required for the project. Preliminary grades and elevations will be determined, and a plan view shows the limits of improvements, identifying the work to be constructed, miscellaneous details, and typical section will be provided. Based upon the results of the HEC -RAS model, ACI will review and identify the required channel improvements and scour protection through the bridge and immediately upstream and downstream of the bridge, as needed. Preliminary grades and elevations will be determined, and limits of improvements will be identified. ACI will prepare a preliminary design for CVWD's maintenance access ramps. It is understood that CVWD already has an existing access ramp on the east side of the LQEC just north of the existing pump station. CVWD might need additional access ramps at the northwest corner and /or southwest corner of Avenue 50 and the LQEC. Deliverables: Floodplain and Bridge Hydraulic Study Report including Construction Cost Estimates for the Channel Slope Lining and Access Ramps 3.3 Roadway Geometric Approval Drawings Page 1 19 The horizontal and vertical layout of Avenue 50 over the La Quinta Evacuation channel is developed based on the existing topography and results of the findings of the project data gathering, review of available data and recommendations provided in the Preliminary Floodplain and Bridge Hydraulics Study. The roadway concept will include a base vertical profile, one base horizontal layout, and one alternative, as directed by the city. Conceptual layouts will be prepared to a 30% level of completion based on approved street sections. Design features are based on the Caltrans Highway Design Manual and AASTHO's Policy on Geometric Design of Highways and Streets and City of La Quinta Standard Plans. Geometric design data and key project features such as bridge abutment locations, roadway approach reconstruction, reconstruction of curb, gutter, and sidewalk, retaining walls, limits of grading, CVWD access ramps, and disposition of existing utilities will be identified. The Geometric Approval Drawings shall contain 20 -scale site layout plans consisting of one title sheet, four plan and profile sheets and one detail sheet that focusses on channel grading. The profile will show the roadway and bridge deck finished surface and the top of rail. Limits of construction, project dimensions, and general identification of work shall be shown on the Geometric Approval Drawings (GAD's). A 40 -Scale Right of Way Requirements map is prepared identifying the existing right of way and parcels and estimation of limits of Temporary Construction Easements and areas of right of way takes for each parcel shown in the table. A Conceptual Construction Cost Estimate for each alternative is prepared based on quantities calculated and available Construction Cost Data. Deliverables: Geometric Approval Drawing (35% complete roadway layout), Draft Right of Way Requirements Map, Conceptual Cost Estimate. 3.4 Bridge and Wall Planning Study The Consultant will perform bridge and wall advance planning study in accordance with Caltrans Office of Special Funded Projects (OSFP) Information and Procedures Guide 3-2. The primary objective for this task is to determine the scope (geometry) and cost of the most feasible bridge and wall types. Internal coordination with the geotechnical engineer and the hydraulic engineer will be made. The bridge planning study will include evaluation of up to two most cost-effective structure types, foundations, bridge lengths, constructability, utility requirements within the bridge, and structural interaction with adjacent roadway facilities. Deliverables: Bridge and Wall General Plans, a Brief Design Memo, and Itemized Cost Estimates. 3.5 Preliminary Stage Construction Plans Upon completion of the GAD, the Preliminary Stage Construction Plans are developed to establish how the bridge is going to be built while minimizing impacts to travelers and utilities. Two Stage Construction Concepts will be investigated. One concept has the bridge built in two phases, one half at a time, and the traffic moved to one the opposite side. The second concept is to build the entire bridge in one phase and two lanes of traffic and pedestrian access are placed on a temporary bypass road. Multiple tiered 40 -scale drawings are prepared showing the limits and offset of the movement of traffic during construction and show typical sections of the bridge structure. Deliverables: Preliminary Stage Construction Plans with a preferred alternative. 3.6 Preliminary Roadway Drainage Study The hydrology study will be performed based on the existing and proposed conditions. Additionally, since the roadway over the bridge will be higher than the existing roadway easterly of the bridge, a sump or low point on the roadway will result, which necessitates the construction of an underground facility and catch basin system that will drain the sump and discharge the flow into the LQEC downstream ofAvenue 50. ACI will prepare design plans for that proposed drainage system including the underground drainage facility designated as South Alternate 1 as identified in the City of La Quinta's Focused Area Drainage Study dated 2016. That proposed facility will be constructed as a parallel system to increase the flow capacity of the existing system and it will include secondary overflow inlets at the existing catch basins to provide an additional and emergency outlet for the tributary flow in the event the existing catch basins become clogged with sediment and urban trash. This scope will include preparation of a roadway drainage study report and hydrology maps including preliminary construction costs for the proposed drainage improvements. Deliverables: Preliminary Roadway Drainage Study Report and Plans including Construction Cost Estimates for the Proposed Drainage Improvements 3.7 Preliminary Geotechnical Study As part of the preliminary geotechnical study, no geotechnical explorations and testing are planned. The geotechnical information available in the vicinity of the project site will be used to perform preliminary engineering analyses and reporting. Two reports are planned to be prepared during this phase as summarized below: Preliminary Foundation Report (PFR) and Preliminary Geotechnical Report (PGR). Deliverables: PFR and PGR 3.8 Bridge Aesthetics and Landscape Modifications Study Bridge Aesthetics and Landscape Modifications Study consists of conducting a site visit to evaluate the existing site conditions and current aesthetics conditions and participate in a landscape and aesthetics kick-off meeting. Then utilizing the feedback and comments received from the landscape and aesthetics kick-off meeting up to 6 color exhibits illustrating proposed aesthetics concepts will be created and a Conceptual Landscape Plan will be prepared illustrating the intended design elements for review and approval. This task includes two photo simulations illustrating the current and proposed project conditions. The assumed limits of the landscape are the median and parkway adjacent to Doral St. only. Deliverables: Up to six color aesthetics exhibits, One Conceptual Landscape Plan, Two Photo Simulations illustrating before and after the project improvement conditions. Page 1 20 3.9 Bridge Type Selection Study Based on the final approved roadway geometric design drawings for the preferred structure alternative, the Consultant shall prepare preliminary bridge design in approximately 30% design completion level including performing preliminary structural design and seismic analyses in accordance with Caltrans bridge design standards and California -amended AASHTO LRFD Bridge Design Specifications. This step of bridge type selection shall be completed and approved by the city before extensive bridge design work for the final PS&E is performed. The two most feasible and cost-effective structure options shall be identified. CNS will evaluate seismic performance of the preferred structure option to satisfy Caltrans' Seismic Design Criteria. CNS will work with the team's geotechnical engineer to determine the foundation type, and the hydraulic engineer to establish the water surface elevation, freeboard, and bridge length to accommodate the designated flood rate. The preliminary structure study shall be summarized in a Bridge Type Selection Report (BTSR). The Consultant shall submit the BTSR to the city and Caltrans for review and concurrence. The Consultant shall attend a virtual bridge type selection meeting with Caltrans SLA and respond to comments. Deliverables: Bridge Type Selection Report and Response to Agency Review Comments 3.10 Preliminary Right of Way Supports and Cost Estimates Monument will evaluate the potential right-of-way requirements, affected parcels, and associated preliminary capital costs related to each alignment alternative under consideration for the proposed project.

Dokken will also work with KOA to estimate project -related VMT for use in operational air quality emissions modeling for use in the Air Quality Report. It is assumed that the Project will result in a less -than -significant impact relating to VMT as the Project is currently included City's General Plan and in SCAG's Regional Transportation Plan / Sustainable Communities Strategy and would not result in a net increase in VMT above what is included in those plans. As the project will expand Avenue 50 from 3 lanes to 4 lanes along the project segment, the project represents an increase in roadway capacity, and therefore has the potential to result in an increase in VMT. Thus, a VMT analysis will be prepared for the project using the RIVCOM model runs conducted for the project as part traffic study outlined in Task 3.1. Per the City of La Quinta Vehicle Miles Traveled Analysis Policy, transportation projects will result in a significant VMT impact when the project results in a net increase in VMT greater than that consistent with the increase outlined in SCAG's Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). The Federal Transportation Improvement Program (FTIP), which serves as the basis for SCAG's RTP, includes the project improvements (RIV 16090 1 /RIV 18040 1). Thus, the potential increases in VMT resulting from the project are already reflected in the RTP/SCS and the project is not anticipated to result in a significant VMT impact. Nonetheless, the project is providing additional project features which will reduce the VMT impact of the project. This includes the addition of Class Il bicycle lanes and pedestrian facilities, which will eliminate an existing gap in the City's bicycle and pedestrian networks. In addition, the bicycle lanes will be designed to accommodate neighborhood electric vehicles (NEVs), expanding the NEV network coverage within the City. KOA will quantify the VMT reduction associated with these facilities based on the latest information from the California Air Pollution Controller Officers Association (CAPCOA). If necessary, KOA will work with the City to identify other projects or programs that can be implemented to further reduce the VMT of the project. Deliverables: VMTAnalysis Technical Memorandum 4.15 Administrative Initial Study/Mitigated Negative Declaration (IS/MND) Dokken, will incorporate the purpose and need/project description and the technical studies into the draft document.
