BACKGROUND INFORMATION: California enacted Senate Bill (SB) 5 in 2007 titled "Central Valley Flood Protection Act of 2008." SB 5 defines "urban level of flood protection" as the "level of protection that is necessary to withstand flooding that has a one -in -200 chance of occurring in any given year, using criteria consistent with, or developed by, the California Department of Water Resources." The bill is intended to strengthen flood management within the Sacramento -San Joaquin Valley region. This act and subsequent amendments required the affected communities to amend their General Plans no later than July 2, 2015 and Zoning Ordinances within 12 months of the completion of the General Plan Amendment. According to the Best Available Maps (BAM) published by the Department of Water Resources, City of Lodi generally falls into the Zone X500 (tan shaded area) with some area inside the Zone AE and Zone X (blue shaded area) as indicated in Exhibit A. Zone X500 is defined by the BAM as: "the areas of 0.2 percent annual chance flood, areas of the one percent chance flood, with average depths of less than one -foot or with drainage areas less than one square mile." The definition of flooding by the Federal Emergency Management Agency (FEMA) is considered as areas with flood depth of more than three feet. When SB 5 was implemented, staff interpreted the above referenced map to mean that all new developable areas inside the 2010 General Plan are in the 500 -year zone and are therefore within the 200 -year flood protection area. This interpretation eliminated the need for a General Plan Amendment. Current staff recently revisited past analysis and concluded that the City must still amend the General Plan and Zoning Code with a defined 200 -year floodplain map in order to comply with the SB 5 requirements. Although there is no specific enforcement authority for the requirement, SB 5 requires cities and counties to make a finding related to the 200 -year level of flood protection as part of the entitlement process or risk potential litigation. SB5 requirements are State requirements that exceed FEMA's 100 -year flood protection requirement. The City is fully compliant with FEMA's 100 -year flood protection requirement. Staff solicited Kjeldsen, Sinnock & Neudeck, Inc. (KSN) to prepare a proposal to develop the 200 -year floodplain map. The map will be used by the City to establish findings for new developments relating to the 200 -year flood protection level. KSN is a well-established civil engineering firm that specializes in flood protection and is considered an expert regarding SB 5 requirements. KSN has worked with the ---- APPROVED: Steph chwabauer,City'Manager K:\WP\FLOOD\SB 5 CertificationCPSA_KSN_SB5.doc 11/27/2017 Adopt Resolution Authorizing City Manager to Execute Professionat Services Agreement with Kjeldsen, Sinnock & Neudeck, Inc., of Stockton, for 200 -Year Floodplain Evaluation and Delineation ($228,800), and Appropriating Funds ($228,800) December 6, 2017 Page 2 State on SB 5 at both policy and technical levels, and they have been involved with numerous projects related to SB 5 in San Joaquin County, Sacramento County, and the surrounding areas. KSN has prepared the 200 -year floodplain maps for the cities of Lathrop and Stockton. KSN's proposal includes collecting existing flood and topographic data, performing hydraulic and hydrologic analysis of the Mokelumne River, and the City of Lodi, to determine the 200 -year flood protection boundary, and developing the 200 -year flood protection map. After the map is completed, KSN will assist the City in acquiring State approval as required by SB 5, before adoption by the City. Upon State approval, City staff will follow up with the General Plan and Zoning Code amendments. Staff recommends Council authorize the City Manager to execute a Professional Services Agreement with Kjeldsen, Sinnock & Neudeck, Inc., of Stockton, for 200 -year floodplain evaluation and delineation, in an amount not to exceed $228,800; and appropriating funds in the amount of $228,800 from the Fund Balance of the Community Development Fund (Fund 270). The cost of the 200 -year flood protection certification services and all other related costs will be reimbursed by development. Staff will return with a resolution creating the fee, consistent with the notice required by state law. FISCAL IMPACT: If this work is not performed on a citywide basis, each development will be required to obtain individual compliance. This approach is not efficient and will slow the pace of development and the resulting fee revenues realized by the City. Since SB 5 applies only to developments approved after July 2016, the total cost of the 200 -year flood protection certification services and all other related costs will be reimbursed by development.

MAGDICH, City Attorney California corporation By: By: Name: Title: Attachments: Exhibit A — Scope of Services Exhibit B — Fee Proposal Exhibit C — Insurance Requirements Exhibit D — Federal Transit Funding Conditions (if applicable) Funding Source: (Business Unit & Account No.) Doc ID:K:\WP\PROJECTS\PSA's\2017\KSN Floodplain PSA.doc CA:Rev.01.2015 8 Exhibit A/B SCOPE OF WORK City of Lodi 200 -Year Floodplain Evaluation & Delineation California state law requires all cities and counties within the Sacramento -San Joaquin Valley, as defined in California Government Code Section 65007(g), to make a Finding related to an urban level of flood projection (200 -Year) before (1) entering into a development agreement; (2) approving a discretionary permit or entitlement for any property development or use, or approving a ministerial permit that would result in construction of a new residence for a project that is located in a flood hazard zone; or (3) approving a tentative map/parcel map. The City of Lodi (City) has requested that Kjeldsen, Sinnock, & Neudeck, Inc. (KSN) conduct a 200 -Year floodplain evaluation for Lodi, and delineate the extents and depths of the Lodi 200 -Year floodplain (200 -Year Floodplain Map). The 200 -Year Floodplain Map will be used by the City when making a Finding related to an urban level of flood projection for new development. The following scope of work describes the tasks necessary to develop the 200 -Year Floodplain Map. Task 1- Project Management This task includes the management activities to ensure that the project is completed on time, within budget, and adequately resolves the issues facing the City of Lodi. This will include preparing invoices and coordinating amongst the differing disciplines involved in the project. The Kick-off meeting will be scheduled shortly after the notice to proceed is received. Deliverables: Kick-off meeting, invoices. Task 2 - Topographic Data Acquisition and Processing Topographic data is needed for both hydraulic modeling and floodplain mapping. To defray costs, KSN proposes to use the Light Detection and Ranging (LiDAR) data acquired by the California Department of Water Resources (DWR) in support of its Central Valley Floodplain Evaluation and Delineation Program (CVFED). This post - processed LiDAR will provide KSN with bare earth topographic data for non -channel areas suitable for hydrologic and hydraulic modeling and floodplain mapping tasks. Upon receipt of the CVFED LiDAR data from DWR, KSN will process this data into a digital elevation model (DEM). KSN will perform a quality control check by comparing field surveyed locations against the elevations determined from the LiDAR. For the hydrologic modeling, topographic data needs extend beyond the areas captured under CVFED. In order to meet this need, KSN will acquire topographic data from the National Elevation Dataset (NED), which is maintained by the United States Geological Survey (USGS). This coarse data (approximately 10 meter resolution) will only be used to delineate watershed boundary extents for the hydrologic modeling. No hydraulic modeling or floodplain delineation will be performed on this topographic data. Deliverables: DEM can be provided upon request. Task 3 - Field Data Collection We have reached out to a number of public agencies (EBMUD, DWR, and San Joaquin County) to ascertain if an existing hydrologic and hydraulic models for the Mokelumne River between Camanche Dam and Lodi exists. We Corporate Office. 711 N Pershing Avenue 1 Stockton, CA 95203 1 209-946-0268 1 vwvnwi.ksninc.com West Sacramento' 1550 Harbor Boulevard. Suite 212 j West Sacramento. CA 95691 916-403-5900 Ii( CITY OF LODI 200 YEAR FLOODPLAIN MAP S November 3, 2017 IN {, Page 2 of 7 have not been able to locate any existing models, therefore new Mokelumne River models will need to be developed. (We will utilize existing models for Bear Creek and Pixley Slough to delineate floodplains in southern Lodi.) In order to develop quality hydrologic and hydraulic models, detailed information for bridges, culverts, dams and channels are needed. KSN has identified the below structures on the Mokelumne River for which detailed information will need to be acquired. A tiered approach to collecting this data will be utilized. KSN will first exhaust municipal, county, and state records for as -built drawings of the below structures. Once as- built drawings are located, they will be examined to ensure that they contain sufficient information for the modeling effort. If any structures still lack sufficient information, KSN field survey crews will be deployed to capture the remaining information. Mokelumne River • Central California Traction Company Railroad (CCTC) • California Highway 99 — North Bound • California Highway 99 — South Bound • Union Pacific Railroad • Woodbridge Dam • Lower Sacramento River Road • Golf Cart Path approximately 0.4 miles downstream of Lower Sacramento Road The primary limitation of LiDAR topographic data is that the LiDAR beams are reflected by water, thus resulting in no reliable information below the surface of water bodies. In order to accurately portray the channel capacity and flood wave routing for the Mokelumne River, additional data will be needed. KSN will deploy field crews to capture detailed channel cross sections for the reach being hydraulically modeled. This station and elevation data will be incorporated into the hydraulic model. Areas between the surveyed locations will be interpolated by HEC - RAS automated routines and reviewed by the hydraulic modeler. Deliverables: None anticipated; however the field notes and total station records can be provided upon request. Task 4 - Hydrologic Analysis In order to develop an accurate hydraulic model, the amount and timing of floodwaters expected in the waterways needs to be known. Therefore KSN will develop a detailed hydrologic model for the Mokelumne River using the Hydrologic Engineering Center's Hydrologic Modeling System (HEC -HMS) Software. Using the LiDAR and NED topography, KSN will delineate subbasins for the Mokelumne River Watershed upstream of the Woodbridge Dam. Applicable hydrologic characteristics (e.g. lag time) for each subbasin will be calculated from the below data sources and the resultant data entered into modeling software. • Precipitation — NOAA PF server • Land cover — NLCD • Soil data — WebSoil Mart • Peak streamflow records — USGS Gage Websites • Camanche Dam information — EBMUD or public records for Stage -Storage curves and flood storage reserve. K s CITY OF LODI 200 YEAR FLOODPLAIN MAP November 3, 2017 Page 3 of 7 The initial model results will be calibrated with the flow records from the 1955 peak flow event at the USGS Gage 11323500 — Mokelumne River below Camanche Dam. The calibrated model peak flow results will then be compared to a Bulletin 17B/C analysis of the same Mokelumne River gage. The resulting 200 -year hydrographs developed for the Mokelumne River will then be used in the hydraulic modeling. For the Bear Creek and Pixley Slough model, we will utilize the modeling already conducted by Stockton to develop 200 year flood hydrographs. A meeting with City Staff will be held to discuss the results of the hydrologic analysis. Deliverables: Hydrologic technical memo (approximately 4-6 pages) with all HEC -HMS model inputs and outputs in digital format and supporting spatial data in ESRI GIS format; Hydrologic Analysis Review Meeting. Task -5 Hydraulic Analysis In order to determine the 200 year level of flood protection for Lodi, the hydrographs developed in the hydrologic modeling need to be routed through the Mokelumne River, Bear Creek, and Pixley Slough. KSN will do so using the Hydrologic Engineering Center's River Analysis System (HEC -RAS). In order to minimize the amount of time and modeling required to determine the 200 year level of flood protection in Lodi, KSN proposes to start the hydraulic modeling upstream of where the current effective FEMA 500 year floodplain starts. This is the first location where the 500 year flow leaves the Mokelumne River channels downstream of Camanche Dam and thus represents the earliest that the 200 year flow would do the same. It is located approximately two miles upstream of the CCTC Railroad crossing of the Mokelumne River. The downstream limit of the Mokelumne River study is proposed to be near the downstream limits of the town of Woodbridge. This location is recommended due to the potential for floodwaters to leave the channel and potentially impact Lodi and is approximately one mile downstream of Lower Sacramento Road. The limits of study for the Mokelumne River are presented below in Figure 1. KSN's proposed hydraulic modeling approach is the exact same in nature as to how the CVFED models were developed with one notable exception: one comprehensive hydraulic model will be utilized instead of CVFED's dual model approach. This approach takes advantage of the nearly five years in technological improvements in hydraulic modeling: specifically two dimensional hydraulic modeling. KSN will develop a single HEC -RAS model which models both the channel portions of the Mokelumne River and the overbank floodplains in one single package. KSN will model the channel of the Mokelumne using HEC-RAS's one dimensional unsteady flow computational engine, while the overbanks will be modeled using HEC-RAS's two dimensional computational engine. Unlike in the CVFED program, Lodi will be able to take advantage of HEC-RAS's inbuilt ability to transfer flows between the two different routines. CVFED had to make due with manual transfers between HEC -RAS and FLO-2D which increased time, introduced multiple avenues for errors and required additional model stabilization efforts. The structure data and channel data collected during the field data collection phase will be used to supplement the LiDAR topographic data. The connection between the one dimensional and two dimensional domains will be made using HEC -RAS lateral weir connections and will be placed at the point where the slope breaks away from the Mokelumne River. K CITY OF LODI 200 YEAR FLOODPLAIN MAP N November 3, 2017 in Page4of7 Manning's roughness values for the channel and overbank areas, which affect how quickly the floodwaters move through the system, will be calculated based upon a combination of site visits, field data collection photography, aerial imagery, and publically available land cover data. _g" 411 h�1-.11004 Ciry of Lodi • Mp1elw:nne Ri.er::4Ar L..1, L00(CpL ' need Ina..mnee Tonna A.

The two dimensional model will be iteratively refined with added layers of detail being added after to focus efforts on areas actually inundated by the 200 year flood event. Structures in the overbank (e.g. culverts through railway embankments, highway underpasses) will be estimated from aerial imagery and/or site visits and primarily modeled using either lateral structures in the two dimensional grid in the case of culverts, or using topographic adjustments in the case of bridges. This method was used in the CVFED program for selected off -stream structures. Critical topographic features, such as roads, larger ditches, and berms, will have break lines created within HEC - RAS to ensure that the two dimensional grid properly accounts for their impact upon the floodwaters. K S N iE CITY OF LODI 200 YEAR FLOODPLAIN MAP November 3, 2017 Page 5 of 7 The Mokelumne River HEC -RAS model will be calibrated to the 1955 and 2017 flood events at the temporary benchmarks identified in the City of Lodi drawings 86D053 & 017D002. These benchmarks identify high water marks from several different flood events in Lodi. The 1955 event was selected as it was the highest flow event within the period of record for the Mokelumne River Gage below Camanche Dam and for which high water marks were available. The 2017 flood event was selected due to its recentness. As it was so recent, the model will be calibrated to ensure that the hydraulic responses on the rising and falling limbs of the hydrographs will be reflective of current upstream conditions. KSN proposes to acquire the existing City of Stockton 200 year flood model for Pixley Slough and Bear Creek. KSN understands that the specific modeling software that was used in that project has certain versions that preclude expanding the model footprint once built. KSN will evaluate the Pixley Slough and Bear Creek model to determine if the model footprint can be extended further north to the limit of inundation caused by Pixley Slough and Bear Creek. If the model can be extended, KSN will do so and use that information for the Pixley Slough and Bear Creek inundation extents. If, the model is unable to be extended, KSN will extract the necessary information from that model to create a HEC -RAS two-dimensional model accounting for the impacts of Pixley Slough and Bear Creek using similar methods described above for the Mokelumne River's modeling with the exception that a one dimensional component to the model is very unlikely needed to satisfy Lodi's needs. Both the Mokelumne River model and the Pixley Slough and Bear Creek models will be simulated until the flood wave has passed through the model and peak stages have occurred throughout the model. This will ensure that areas of Lodi are not being under predicted for the 200 year flood event. Once the hydraulic analysis is completed, but before the analysis is presented to the expert peer reviewer, KSN will meet with City Staff to review the results of the hydraulic analysis. Deliverables: Hydraulic technical memo (approximately 8-10 pages) with all model inputs and outputs in digital format and supporting spatial data in Environmental Systems Research Institute's (ESRI) Geospatial Information System (GIS) format. Comments and responses from the peer expert review will be included in this technical memo as an appendix. Pre -expert review draft hydraulic results meeting. Post expert review meeting. Task 6 - Map Development KSN will develop both digital and hard copy maps for use in Lodi administering their 200 year floodplain. The maps will be developed using the LiDAR, hydraulic modeling results, and base map data to be provided by Lodi. The maps will be prepared using ArcGIS. The maps will present the 200 year floodplain extents, the 200 year floodplain depths, and the 200 year water surface elevations. While the engineering analyses are underway, KSN GIS Analysts will prepare a draft template for the maps with a layout scheme. The template and layout scheme will be reviewed with appropriate City Staff and any revisions necessary will be incorporated into the template. Raster products will be based upon a 10' cell size. Maximum depth and maximum water surface elevation contours will be developed at whole foot intervals. Maximum depth and maximum water surface rasters will be developed. Once the draft maps have been generated with the engineering analyses results presented, KSN will meet with appropriate City Staff to review the content of the maps evaluating primarily cartographic and aesthetic K CITY OF LODI 200 YEAR FLOODPLAIN MAP NNovember 3, 2017 I� Page 6 of 7 considerations along with GIS spatial file formats and schema. Once any revisions necessary have been incorporated into the maps from that meeting, a final project close out meeting will be held. Deliverables: Final technical memo (compilation of previous TMs) in both digital and hardcopy format. 2 complete sets of hardcopy maps (approximately 24" by 36"). Digital copies of the maps both in portable document format (PDF) and ESRI GIS format. Map and GIS data template meeting. Draft Map Results meeting. Final Project Closeout meeting. To comply with DWR ULOP criteria, the City of Lodi will need to submit the hydraulic model and results to undergo an independent expert peer quality review process. Findings from the review process will be documented provided to Lodi and KSN. KSN will coordinate with both Lodi, and the expert peer reviewer to ensure that the model is revised as appropriate. Should any findings from the quality review process not be incorporated, the reasoning behind the non -incorporation and any supporting justification shall be documented in the final hydraulic technical memo and provided to the expert peer reviewer. After the receipt of the expert peer reviewer's findings, KSN, the expert peer reviewer and City staff will meet to review the findings. Please note the expert peer reviewer must contract directly with the City of Lodi, and is not included in the costs below. KSN will provide the City will recommendations for peer reviewers.
