REFLECTING ADDENDUM 3
the nature of the work or from the action of the elements, or from any unforeseen obstructions or difficulties which may be encountered in the prosecution of the work; for all risks of every description connected therewith; for all expenses of the work, as herein specified; for all liability and other insurance, for all overhead and other expenses incident to the work; all according to the Contract Drawings, the Special Provisions, the Details, the instructions and the requirements of the City.
Article III. Labor Discrimination.
Attention is directed to Section 1735 of the Labor Code, which reads as follows:
"No discrimination shall be made in the employment of persons upon public works because of the race, color, national origin or ancestry, or religion of such persons and every contractor for public works violating this section is subject to all the penalties imposed for a violation of this chapter." In connection with the performance of work under this contract, the Contractor agrees as follows:
(a) The Contractor will not willfully discriminate against any employee or an applicant for employment because of race, color, religion, ancestry, or national origin. The Contractor will take affirmative action to ensure that applicants are employed and that employees are treated during employment without regard to their race, color, religion, ancestry, or national origin. Such action shall include, but not be limited to, the following: employment, upgrading, demotion or transfer; recruitment or recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship. The Contractor agrees to post in conspicuous places, available to employees and applicants for employment, notices to be provided by the awarding authority setting forth the provisions of this Fair Employment Practice section. (b) The Contractor will send to each labor union or representative of workers with which he or she has a collective bargaining agreement or other contract or understanding, a notice, to be provided by the awarding authority, advising the said labor union or worker's representative of the Contractor's commitments under this section, to employees and applicants for employment. (c) The Contractor will permit access to his or her records of employment, employment advertisements, application forms and other pertinent data and records by the Fair Employment Practices Commission, City of Ukiah or any other appropriate agency of the State of California designated by the awarding authority, for the purposes of investigation to ascertain compliance with the Fair Employment Practices section of this contract. (d) A finding of willful violation of the Fair Employment Practices section of this Contract or of the Fair Employment Practices Act shall be regarded by the awarding authority as a basis for determining the Contractor to be not a "responsible bidder" as to future contracts for which such Contractor may submit bids, for revoking the Contractor's pre-qualification rating, if any and for refusing to establish, reestablish or renew a pre-qualification rating for the Contractor.
The City of Ukiah shall deem a finding of willful receipt of written notice from the Fair Employment Practices Act to have occurred upon that it has investigated and determined that the Contractor has violated the Fair Employment Practices Act and has issued an order under Labor Code Section 1426 or obtained an injunction under Labor Code Section 1429.
Upon receipt of such written notice from the Fair Employment Practices Commission, the City shall notify the Contractor that unless he or she demonstrates to the satisfaction of the awarding authority within a stated period that the violation has been corrected, his or her pre-qualification rating will be revoked at the expiration of such period. (e) The Contractor agrees that should the City determine that the Contractor has not complied with the Fair Employment Practices section of this Contract, then pursuant to Labor Code Section 1735 and 1775 the Contractor shall, as a penalty to the City, forfeit for each calendar day or portion thereof,
RIVERSIDE PARK REGENERATION 90 Spec No.24-05
REFLECTING ADDENDUM 3
for each person who was denied employment as a result of such non-compliance, the penalties provided in the Labor Code for violation of prevailing wage rates. Such monies may be recovered from the Contractor. The City may deduct any such damages from any monies due the Contractor. (f) Nothing contained in this Fair Employment Practices section shall be construed in any manner of fashion so as to prevent the City or the State of California from pursuing any other remedies that may be available at law.
(g) Prior to awarding the Contract, the Contractor shall certify to the awarding authority that he or she has or will meet the following standards for affirmative compliance, which shall be evaluated in each case by the awarding authority:
(1) The Contractor shall provide evidence, as required by the City that he or she has notified all supervisors, foremen and other personnel officers in writing of the content of the anti-discrimination clause and their responsibilities under it.
(2) The Contractor shall provide evidence, as required by the City, that he or she has notified all sources of employees’ referrals (including unions, employment agencies, advertisements, Department of Employment) of the content of the anti-discrimination clause. (3) The Contractor shall file a basic compliance report, as required by the City. Willfully false statements made in such reports shall be punishable as provided by law. The compliance report shall also spell out the sources of the work force and who has the responsibility for determining whom to hire, or whether or not to hire.
(4) Personally, or through his or her representatives, the Contractor shall, through negotiations with the unions with whom he or she has agreements, attempt to develop an agreement which will:
a. Spell out responsibilities for nondiscrimination in hiring, referral, upgrading and training. b. Otherwise implement an affirmative anti-discrimination program in terms of the unions' specific areas of skill and geography to the end that qualified minority workers will be available and given and equal opportunity for employment.
(5) The Contractor shall notify the City of opposition to the anti-discrimination clause by individuals, firms or organizations during the period of its pre-qualification. (h) The Contractor will include the provisions of the foregoing paragraphs 1 through 5 in every first tier subcontract so that such provisions will be binding upon each such subcontractor. (i) The "Fair Employment Practices Certification" must be completed and signed prior to the time of submitting the bid.

The SWPPP will be revised when:
• There is a 2022 CGP violation (2022 CGP Section VI.Q.1); • There is a reduction or increase in total disturbed acreage (2022 CGP Section III.F.2. and F.4);
• BMPs are not effective and are not resulting in a reduction or elimination of pollutants in stormwater discharges and authorized non-stormwater discharges (2022 CGP Section VI.Q.1 and Attachment E Section III.C.5);
• There is a change in the project duration that changes the project Risk Type (2022 CGP Section III.F.1);
• Dischargers with projects where all construction activities (including passive treatment, active treatment systems, and/or active equipment) will be suspended for 30 days or more (2022 CGP Section III.G);
• There is a change in construction or operations that may affect the discharge of pollutants to surface waters, groundwater(s), or a municipal separate storm sewer system (MS4) (2022 CGP Sections IV.O. and VI.Q.1); or
When deemed necessary by the QSD. The QSD has determined that the changes listed in Table 1-1 can be field determined by the QSP. All other changes will be made by the QSD as formal amendments to the SWPPP.

Section 1 SWPPP Requirements
1.1 INTRODUCTION
This Stormwater Pollution Prevention Plan (SWPPP) is designed to comply with California’s General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities (2022 CGP), State Water Resources Control Board (State Water Board) Order No. 2022-0057-DWQ (NPDES No. CAS000002) (Appendix S). This SWPPP has been prepared following the 2022 CGP SWPPP Template for Traditional Projects provided in the California Stormwater Quality Association (CASQA) Stormwater Best Management Practice (BMP) Handbook: Construction (CASQA 2023).
This project is considered a traditional construction project.
In accordance with the 2022 CGP, Section IV.O, this SWPPP is designed to address the following:
• Identification of all pollutants, their sources, and control mechanisms, including sources of sediment associated with all construction activities (e.g., sediment, paint, cement, stucco, cleaners, site erosion);
• Pollutant source assessments, including a list of potential pollutant sources and identification of site areas where additional BMPs are necessary to reduce or prevent pollutants in stormwater and authorized non-stormwater discharges, per the minimum requirements when developing the pollutant source assessment; • Description of site-specific BMPs implemented to reduce or eliminate stormwater pollution;
• Where not otherwise required to be under a Regional Water Quality Control Board (Regional Water Board) permit, all non-stormwater discharges are identified and either eliminated, controlled, or treated;
• Site BMPs are effective and result in the reduction or elimination of pollutants in stormwater discharges and authorized non-stormwater discharges from construction activity to the Best Available Technology/Best Control Technology (BAT/BCT) standard; and;
• Stabilization BMPs are installed to reduce or eliminate pollutants after construction is completed are effective and maintained; and
• Calculations and design details, as well as BMP controls, are complete and correct.
The Riverside Park Regeneration Project (Project or Site) comprises approximately 8.6 acres, of which 6.52 will be disturbed. The Project is located at 1281 E Gobbi Street in Ukiah, California.
The property is owned by the City of Ukiah and is being developed by the City as a park. The project’s location is shown on the Site Maps in Appendix A.

Section 2 Project Information
2.1 PROJECT AND SITE DESCRIPTION
2.1.1 Site Description
The Riverside Park Regeneration Project site is Risk Level 2 that will include approximately 6.52 acres of ground disturbance located at 1281 East Gobbi Street in Ukiah, California (see Sheet L0.0 in Appendix A). The project site is located at the eastern end of East Gobbi Street in Riverside Park. The project site is located approximately 200 feet west of the Russian River.
The project is located at latitude 39.143399, and longitude -123.182880.
2.1.2 Existing Conditions
As of the initial date of this SWPPP, the project site is undeveloped with some vegetated areas, some dirt roads, and three debris piles of concrete, asphalt, and street sweepings. Some household debris is also present in scattered locations. Parts of the project site were previously used at different times for sewage treatment ponds, a trap shooting range, and a police shooting range. The sewage treatment ponds and shooting ranges were previously removed by 1978. Soil sampling and analysis was conducted to test for residual contamination; the results of this analysis are in Appendix Q. The results identified one hot spot of soil with lead and pesticides at concentrations above regulatory action levels (see Sheet L1.3 in Appendix A). This hot spot area will be removed and disposed of at an offsite disposal facility permitted to accept the waste.
2.1.3 Existing Drainage
The project site is relatively level and hummocky with three debris piles. The elevation of most the project site ranges from 580 to 585 feet above mean sea level (msl). The two small jurisdictional wetlands shown on Sheet L1.2 are seasonal wetlands likely fed by groundwater or underflow from the river and are as low as 572 feet above msl. The three debris piles shown on Sheet L1.2 rise as high as about 594 feet above msl. Surface drainage at the site is internal and does not directly drain to the Russian River. Stormwater infiltrates into the onsite soil or flows to the internal jurisdictional wetlands. Existing site topography, drainage patterns, and stormwater conveyance systems are shown on Sheet L1.0 in Appendix A.
The project does not directly discharge to any surface water bodies. However, the site is about 200 feet west of the Russian River. This reach of the river is identified as a 303(d) listed water body: Russian River HU, Upper Russian River HA, Ukiah HSA. The water quality impairments (303 (d) list and TMDLs identified in the 2022 CGP Table H-1 for the receiving waters are identified in Table 2-1.

for the 2022 CGP
2.1.4 Geology and Groundwater
The site is underlain by a heterogenous mix of mostly gravel, sand, and silt from previous poorly-documented fill events. Groundwater occurs beneath the site at a few feet below grade, and is likely a combination of groundwater migrating from upland areas from the west and underflow from the Russian River. The groundwater gradient is unknown but assumed to be southerly since the Russian River also flows south.
2.1.5 Project Description
Project grading will occur on approximately 6.52 acres of the project site, which comprises approximately 76 percent of the total area. The limits of grading are shown on Sheet L1.3 through L1.6 in Appendix A. Grading will include both cut and fill activities. About 1,140 cubic yards of clay soil would be imported to the site because the existing soils are of poor quality for vegetation. Approximately 90 cubic yards of decomposed granite would be imported and installed on the walking pathways shown on Sheet L2.0 in Appendix A.
For export, about 228 cubic yards of contaminated soil will be disposed of at an offsite facility permitted to accept the waste (see Sheet L1.3 in Appendix A). The soil sampling report in Appendix Q provides further information regarding the contaminated soil. Approximately 2,260 cubic yards of existing waste piles (see Sheet L1.2 in Appendix A) consisting of concrete, relic asphalt, and other debris will be removed and recycled to the extent possible at a facility permitted to accept the material. Approximately 1,002 cubic yards of selected non-native invasive plant species such as Himalayan blackberry and other exotic species would be removed using hand tools and light equipment such as a weed whacker. The non-native vegetation will be sent to an offsite green waste facility.
Construction activities will be conducted in phases: (1) removal of contaminated soil and debris piles, (2) grading to final topography and installation of public access improvements as shown on Sheet L2.0 in Appendix A, and (3) revegetation.
2.1.6 Developed Condition
Post-construction surface drainage will be internal with stormwater infiltrating into the subsurface or flowing to the two jurisdictional wetlands, as it does now. Post-construction drainage patterns and conveyance systems are presented on Sheets L2.0 and L2.1 in Appendix A.

2.2 PERMITS AND GOVERNING DOCUMENTS
In addition to the 2022 CGP, the following documents have been taken into account while preparing this SWPPP:
• Regional Water Board Basin Plan requirements
• Contract Documents
• County of Mendocino: Flood Hazard Zone Development Permit
2.3 STORMWATER RUN-ON FROM OFFSITE AREAS
Run-on to the site could be generated by overland flow during storm events from offsite areas west of the project site. However, the areas west of the project site are vineyards that control erosion on their site and run-off from the vineyards would be negligible, if any. Nonetheless and as required by the 2022 CGP, silt fences will be installed along the entire border of the project site to manage run-on, if any, as shown on Sheet L1.0 in Appendix A.
CASQA Traditional SWPPP Template 2-4 March 2024
for the 2022 CGP
2.4 FINDINGS OF THE CONSTRUCTION SITE SEDIMENT AND
RECEIVING WATER RISK DETERMINATION
A construction site risk assessment has been performed for the project and the resultant risk level is Risk Level 2.
The risk level was determined through the use of the R-value determined from EPA’s Rainfall Erosivity Factor Calculator for Small Construction Sites at: https://lew.epa.gov/ in accordance with the State Water Board Guidance for multi-year projects at:
https://www.waterboards.ca.gov/water_issues/programs/stormwater/smarts/construction/do cs/rfactor_guide.pdf, and K and LS using the SWRCB GIS file at:
ftp://swrcb2a.waterboards.ca.gov/pub/swrcb/dwq/cgp/Risk/. The risk level is based on project duration, location, proximity to impaired receiving waters, and soil conditions. A copy of the Risk Level determination with the PRDs is included in Appendix B.
Table 2-3 and Table 2-4 summarize the sediment and receiving water risk factors and document the sources of information used to derive the factors.

Risk Level 2 sites are subject to both the narrative effluent limitations and numeric action limitations (NALs). The narrative effluent limitations require stormwater discharges associated with construction activity to minimize or prevent pollutants in stormwater and authorized nonstormwater through the use of controls, structures and best management practices (BMPs).
Discharges from Risk Level 2 site are subject to NALs for pH and turbidity shown in Table 2-5.
This SWPPP has been prepared to address Risk Level 2 requirements (2022 CGP Attachment D).

2.5 CONSTRUCTION SCHEDULE
The site sediment risk was determined based on construction taking place between June 1, 2024, and October 14, 2024. Modification or extension of the schedule (start and end dates) may affect risk determination and permit requirements. The LRP shall contact the QSD if the schedule changes during construction to address potential impact to the SWPPP. The estimated schedule for planned work can be found in Appendix E.
CASQA Traditional SWPPP Template 2-6 March 2024

2.6 POTENTIAL CONSTRUCTION ACTIVITY AND POLLUTANT
SOURCES
Appendix F includes a list of construction activities and associated materials that are anticipated to be used onsite as well as the pollutant source assessment form that was completed for the project. These activities and associated materials will or could potentially contribute pollutants, other than sediment, to stormwater runoff.
A list of construction activities and associated materials that are anticipated to be used on site is provided below. These activities and associated materials could potentially contribute pollutants, other than sediment, to stormwater runoff:
• Excavation and removal of three concrete debris piles and one contaminated soil hot spot (sediment, lead, and residual pesticides)
• Grading and excavation to rework topography and install irrigation system (sediment) • Pouring of concrete pad for kiosk (pH)
• Equipment leaks (fuel, oil, lubricants, coolant)
• General construction waste and litter
The anticipated activities and associated pollutants were used in Section 3 to select the BMPs for the project. Locations of anticipated pollutants and associated BMPs are shown on Sheets L1.0 and L1.1 (BMPs) and L1.3 (contaminants) in Appendix A.
Additionally, proper measures will be taken to ensure that trench spoils or any other soils disturbed during construction activities that are contaminated are not discharged with stormwater or non-stormwater discharges into storm drains or water bodies (except pursuant to a separate NPDES Permit). If contaminated soil is found on site, and the responsible party cannot be identified or fails to take action, the soil will be sampled to determine proper handling and protect public safety. The appropriate local, State, and federal agencies along with the appropriate Regional Water Board will be notified when contaminated soils are observed.
For sampling requirements for non-visible pollutants associated with construction activity, please refer to Section 7.7.1. For a full and complete list of onsite pollutants, refer to the Safety Data Sheets (SDS), which are retained onsite at the construction trailer or are available electronically at the site.
2.7 TMDL REQUIREMENTS
The Russian River is not listed in the 2022 CGP Appendix H. Although the Ukiah reach of the Russian River is a 303(d) listed water body identified for aluminum, manganese, sediment, and temperature, TMDLs have not yet been established for these parameters in this reach of the river.
2.8 IDENTIFICATION OF NON-STORMWATER DISCHARGES
Non-stormwater discharges into storm drainage systems or waterways, which are not authorized under the 2022 CGP and listed in the SWPPP, or authorized under a separate NPDES permit, are prohibited. There are no authorized non-stormwater discharges from this site. Steps will be taken, including the implementation of appropriate BMPs, to ensure that unauthorized discharges are eliminated, controlled, disposed, or treated on-site.
Discharges of construction materials and wastes, such as fuel or paint, resulting from dumping, spills, or direct contact with rainwater or stormwater runoff, are also prohibited.

3.2 EROSION AND SEDIMENT CONTROL
Erosion and sediment controls are required by the 2022 CGP to provide effective reduction or elimination of sediment related pollutants in stormwater discharges and authorized nonstormwater discharges from the Site. Applicable BMPs are identified in this section for erosion control, sediment control, tracking control, and wind erosion control.
3.2.1 Erosion Control
Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to prevent soil particles from detaching and becoming transported in stormwater runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles.
This construction project will implement the following practices to provide effective temporary and final erosion control during construction:
1. Preserve existing vegetation where required and when feasible.
2. The area of soil disturbing operations shall be controlled such that the Contractor is able to implement erosion control BMPs quickly and effectively.
3. Stabilize non-active areas within 14 days of cessation of construction activities or sooner if stipulated by local requirements.
4. Control erosion in concentrated flow paths by applying erosion control blankets, check dams, erosion control seeding, or alternate methods.
5. Prior to the completion of construction, apply permanent erosion control to remaining disturbed soil areas.
Sufficient erosion control materials shall be maintained onsite to allow implementation in conformance with this SWPPP.
The following erosion control BMP selection table, Table 3-2 indicates the BMPs that will be implemented to control erosion on the construction site. Fact Sheets for temporary erosion control BMPs are provided in Appendix G.
These temporary erosion control BMPs shall be implemented in conformance with the following guidelines and as outlined in the BMP Factsheets provided in Appendix G. If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets.

Soil Preparation-Roughening
The three piles of concrete debris shown on Sheet L1.2 will be removed and will be recycled or disposed of at an offsite facility permitted to accept the materials. The one contaminated soil hot spot shown on Sheet L1.3 will be removed and will be disposed of at an offsite facility permitted to accept the materials.
The topography of the site will be graded to flatten the existing hummocky nature, as shown on Sheet L1.3. The two jurisdictional features (i.e., seasonal wetlands) will be cordoned off with silt fencing and will not be disturbed.
Following most of the debris and vegetation removal, rough grading would be implemented within approximately 3.39 acres of the site, including site recontouring to remove relic berms and realign site drainage. Some of the debris removal would need to occur following rough grading necessary to facilitate the removal. Approximately 0.42 acres of fine grading would occur in the upper terrace to redirect drainage away from the adjacent vineyard located to the west. As depicted on Sheet L1.3 n Appendix A, a series of berms and basins would be reconstructed on the site, designed to allow for seasonal off-channel habitat. To facilitate the reestablishment of seasonal wetlands on site, the project will place and compact a 2-inch base layer in re-contoured basins (in and below the 587 elevation contour). As the existing soils are degraded and do not support wetland vegetation, approximately 1,140 cubic yards of clay soil would be imported for this purpose. The site would be planted with ecologically appropriate wetland vegetation (as shown on Sheets L3.0 and L3.1 in Appendix A), with temporary irrigation to establish plantings (as shown on Sheets L4.0, L4.1, and L4.2 in Appendix A).
Inert soil moved during grading would be redistributed onsite at a location southeast of the park’s main parking lot (and south of the BMX track), which currently is used as overflow parking. Disturbed soils throughout the site would be stabilized and reseeded with ecologically appropriate grasses.
3.2.2 Sediment Controls
Sediment controls are temporary or permanent structural measures that are intended to complement the selected erosion control measures and reduce sediment discharges from active construction areas. Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water.
The following sediment control BMP selection table indicates the BMPs that will be implemented to control sediment on the construction site. Fact Sheets for temporary sediment control BMPs are provided in Appendix G.
These temporary sediment control BMPs will be implemented in conformance with the following guidelines and in accordance with the BMP Fact Sheets provided in Appendix G.

3.3.2 Materials Management and Waste Management
Materials management control practices consist of implementing procedural and structural BMPs for handling, storing, and using construction materials to prevent the release of those materials into stormwater discharges. The amount and type of construction materials to be utilized at the Site will depend upon the type of construction and the length of the construction period. The materials may be used continuously, such as fuel for vehicles and equipment, or the materials may be used for a discrete period, such as soil binders for temporary stabilization.
Waste management consists of implementing procedural and structural BMPs for handling, storing, and ensuring proper disposal of wastes to prevent the release of those wastes into stormwater discharges.
Materials and waste management pollution control BMPs will be implemented to minimize stormwater contact with construction materials, wastes, and service areas; and to prevent materials and wastes from being discharged offsite. The primary mechanisms for stormwater contact that shall be addressed include:
• Direct contact with precipitation
• Contact with stormwater runon and runoff
A list of construction activities is provided in Section 2.6. The following Materials and Waste Management BMP selection table, Table 3-5, indicates the BMPs that shall be implemented to

3.5 POST CONSTRUCTION STORMWATER MANAGEMENT MEASURES
Post construction BMPs are permanent measures installed during construction, designed to reduce or eliminate pollutant discharges from the site after construction is completed.
This site is subject to the post-construction requirements of an existing NPDES Phase I or Phase II MS4. ☐ Yes ☒ No
The following source control, site design, and treatment control post-construction BMPs to comply with 2022 CGP Section IV.N.3 have been identified for the site.
The Project includes site recontouring and revegetation with native plants to create about six acres of varied-elevation seasonal floodplain wetlands for storm water and floodwater retention, bio-infiltration, groundwater recharge, and native habitat. An earthen berm would be constructed to enhance wetlands, and new native wetland plantings would be installed. In addition, transitional planting and upland area planting with native trees, shrubs, grasses and annual plants would enhance upland areas. The Project’s upland area plantings are designed to incorporate ecologically-appropriate riparian plants, native to the local region of the Russian River, complying with the California Department of Water Resources (DWR) Model Water Efficient Landscape Ordinance (MWELO).
The Project would implement soil restoration to improve soil moisture retention and microbial balance and provide the essential foundation for restoring the site’s plant communities. Clay soil would be imported for this purpose, described in Section 2.1.5. This portion of the project would also focus on expanding the edge of the riparian forest and restoring site grasslands. The proposed planting plan for this restoration is depicted on Sheets L3.0 and L3.1 in Appendix A.
The proposed irrigation plan is depicted on Sheets 4.0, 4.1, and 4.2.
Completion of the planting and irrigation system would control post construction runoff through improved evapotranspiration by the improved vegetation, improved retention of stormwater for infiltration, and maintaining drainage internal to the project site through infiltration and drainage to the two seasonal (jurisdictional) wetlands internal to the project site.
A plan for the post construction funding and maintenance of these BMPs has been developed to address at minimum five years following construction. Through various partnerships with the Mendocino RCD, Peregrine Audubon, the Sanhedrin Chapter of the California Native Plant Society, the City will conduct ongoing management of the site to include community park patrol, bird walks, invasive plant removal, native plant maintenance, and site monitoring. The post construction plan described above will be funded and maintained as described in the Operations and Maintenance Plan that will be uploaded with the Notice of Termination.

Section 7 Construction Site Monitoring Program
7.1 Purpose
This Construction Site Monitoring Program was developed to address the following objectives:
1. To demonstrate that the site is in compliance with the Discharge Prohibitions and Numeric Action Levels (NALs);
2. To determine whether non-visible pollutants discharged from the construction site and are causing or contributing to exceedances of water quality objectives;
3. To determine whether immediate corrective actions, additional BMP implementation, or SWPPP revisions are necessary to reduce pollutants in stormwater discharges and authorized non-stormwater discharges;
4. To determine whether BMPs included in the SWPPP are effective in preventing or reducing pollutants in stormwater discharges and authorized non-stormwater discharges.
7.2 Applicability of Permit Requirements
This project has been determined to be a Risk Level 2 project. The 2022 CGP identifies the following types of monitoring as being applicable for a Risk Level 2 project.
Risk Level 2
• Visual inspections of BMPs;
• Visual monitoring of the site related to qualifying precipitation events; • Visual monitoring of the site for non-stormwater discharges; • Sampling and analysis of construction site runoff, if any, for pH and turbidity; • Sampling and analysis of construction site runoff, if any, for non-visible pollutants identified during the pollutant source assessments when applicable; and • Sampling and analysis of construction site runoff, if any, as required by the Regional Water Board when applicable.
7.3. Weather and Precipitation Event Tracking
Visual monitoring and inspections requirements of the 2022 CGP are triggered by a Qualifying Precipitation Event. The 2022 CGP defines a Qualifying Precipitation Event as any weather pattern that is forecast to have a 50 percent or greater Probability of Precipitation (PoP) and a Quantitative Precipitation Forecast (QPF) of 0.5 inches or more within a 24-hour period. The event begins with the 24-hour period when 0.5 inches has been forecast and continues on subsequent 24-hour periods when 0.25 inches of precipitation or more is forecast.
7.3.1 Weather Tracking
The QSP should daily consult the National Oceanographic and Atmospheric Administration (NOAA) for the Forecast Weather Table Interface. These forecasts can be obtained at http://forecast.weather.gov. Weather reports should be printed and maintained with the SWPPP in Appendix M. Record the date and time the forecast was printed.
CASQA Traditional SWPPP Template 7-2 March 2024
for the 2022 CGP
7.4 Monitoring Locations
The project site drains internally and does not directly drain to the Russian River. In the unlikely event that drainage from the construction site is discovered, monitoring locations will be selected based on the location of the drainage.
Whenever changes in the construction site might affect the appropriateness of sampling locations, the sampling locations shall be revised accordingly. All such revisions shall be implemented as soon as feasible and the SWPPP amended. Temporary changes that result in a one-time additional sampling location do not require a SWPPP amendment.
7.5 Safety and Monitoring Exemptions
Safety practices for sample collection will be in accordance with the [ENTER TITLE AND PUBLICATION DATE OF CONTRACTOR’S HEALTH AND SAFETY PLAN FOR THE PROJECT OR PROVIDE SPECIFIC REQUIREMENTS IN THIS SECTION]. A summary of the safety requirements that apply to sampling personnel is provided below. • List or state none [To be provided by contractor]
This project is not required to collect samples or conduct visual observations (inspections) under the following conditions (see Section III.B of the 2022 CGP):
• During dangerous weather conditions such as electrical storms, flooding, and high winds above 40 miles per hour;
• Outside of scheduled site operating hours; or
• When the site is not accessible to personnel. Scheduled site business hours are: 7 a.m. to 6 p.m., Monday through Friday.
If monitoring (visual monitoring or sample collection) of the site is unsafe because of the dangerous conditions noted above, then the QSP shall document the conditions for why an exception to performing the monitoring was necessary. The exemption documentation will be filed in Appendix N and must be included in the Annual Report.
7.6 Visual Monitoring
Per Section III.B.2. of Attachment D in the 2022 CGP, “For inactive projects, dischargers may reduce the visual inspection frequency and suspend sampling per Section III.G of the 2022 CGP.
Dischargers shall provide an explanation with supporting information for all missed visual inspections or sampling required by this Attachment, to be included in the Annual Report.” Visual monitoring includes observations and inspections. Inspections of BMPs are required to identify and record BMPs that need maintenance to operate effectively, that have failed, or that could fail to operate as intended. Visual observations of the site are required to observe storm water drainage areas to identify any spills, leaks, or uncontrolled pollutant sources.
Table 7-1 identifies the required frequency of visual observations and inspections. Inspections and observations will be conducted at the locations identified in Section 7.6.3.

2.Most BMPs must be inspected weekly; those identified below must be inspected more frequently. 3 Inspections are required during scheduled site operating hours on days that the forecast predicts at least 0.25 inches of precipitation once the qualifying precipitation event commences.
7.6.1 Routine Observations and Inspections
Routine site inspections and visual monitoring are necessary to confirm that the project is in compliance with the requirements of the 2022 CGP.
7.6.1.1 Routine BMP Inspections
Inspections of BMPs are conducted to identify and record:
• BMPs that are properly installed;
• BMPs that need maintenance to operate effectively;
• BMPs that have failed; or
• BMPs that could fail to operate as intended.
7.6.1.2 Non-Stormwater Discharge Observations
Each drainage area will be inspected for the presence of or indications of prior unauthorized and authorized non-stormwater discharges. Inspections will record:
• Presence or evidence of any non-stormwater discharge (authorized or unauthorized); • Identification and elimination of unauthorized non-stormwater discharges • Pollutant characteristics (floating and suspended material, sheen, discoloration, turbidity, odor, etc.); and
• Source of discharge.
7.6.2 Qualifying Precipitation Event Triggered Observations and Inspections
Visual observations of the site and inspections of BMPs are required prior to a qualifying precipitation event; following a qualifying precipitation event, and every 24-hour period during a qualifying precipitation event. Pre-Qualifying Precipitation Event inspections will be
CASQA Traditional SWPPP Template 7-4 March 2024
for the 2022 CGP
conducted after consulting NOAA and determining that a precipitation event with a 50 percent or greater PoP and a QPF of 0.5 inches or more precipitation within a 24-hour period has been predicted by the National Weather Service Forecast Office.
7.6.2.1 Visual Observations Prior to a Forecasted Qualifying Precipitation Event Within 72 hours prior to a qualifying precipitation event or up to 120 hours prior if extended forecast precipitation data is available, a stormwater visual monitoring site inspection will include observations of the following locations:
• All stormwater drainage areas to identify leaks, spills, or uncontrolled pollutant sources and when necessary, implement appropriate corrective actions. • All BMPs to identify whether they have been properly implemented per the SWPPP and implement appropriate corrective actions, as necessary. • All stormwater storage and containment areas to detect leaks and check for available capacity to prevent overflow.
The QSP must conduct the inspection prior to the qualifying precipitation event. Consistent with the requirements for a qualifying precipitation event, pre-rain BMP inspections and visual monitoring will be triggered by a NOAA forecast that indicates a 50 percent or greater probability of 0.5 inches of precipitation or more in a 24-hour period in the project area.
7.6.2.2 BMP Inspections During a Qualifying Precipitation Event During an extended qualifying precipitation event BMP inspections will be conducted at least once every 24 hours. Qualifying precipitation events are extended for each subsequent 24- hour period forecast to have at least 0.25 inches of precipitation. The BMP inspections are to identify and record:
• If BMPs were adequately designed, implemented and effective. • BMPs that require repair or replacement due to damage. • Additional BMPs that need to be implemented and revise the SWPPP accordingly.
If the construction site is not accessible during the rain event, the visual inspections shall be performed at all relevant outfalls, discharge points, downstream locations. The inspections should record any projected maintenance activities.
7.6.2.3 Visual Observations Following a Qualifying Precipitation Event Within 96 hours following the end of a qualifying precipitation event a stormwater visual monitoring site inspection is required to observe:
• If BMPs were adequately designed, implemented and effective. • BMPs that require repair or replacement due to damage. • Additional BMPs that need to be implemented and revise the SWPPP accordingly.

7.7 Water Quality Sampling and Analysis
7.7.1 Sampling and Analysis Plan for Non-Visible Pollutants in Stormwater Runoff Discharges
This Sampling and Analysis Plan for Non-Visible Pollutants describes the sampling and analysis strategy and schedule for monitoring non-visible pollutants in stormwater runoff discharges from the project site.
Sampling for non-visible pollutants, including those associated with TMDLs will be conducted when (1) a breach, leakage, malfunction, or spill is observed; and (2) the leak or spill has not been cleaned up prior to the rain event; and (3) there is the potential for discharge of non-visible pollutants to surface waters or drainage system.
CASQA Traditional SWPPP Template 7-6 March 2024
for the 2022 CGP
Table 7-2 summarizes the potential non-visible pollutants identified in the pollutant source assessment in Sections 2.6 and 2.7 and the water quality constituent or indicator for that pollutant.

The project has the potential to receive stormwater run-on from the vineyards located adjacent and west of the project site. The run-on has the potential to contribute non-visible pollutants to stormwater discharges from the project.
7.7.1.1 Sampling Schedule
Samples for the potential non-visible pollutant(s) and a sufficiently large unaffected background sample shall be collected during the first eight hours of discharge from rain events that result in a sufficient discharge for sample collection. Samples shall be collected during the site’s scheduled hours and shall be collected regardless of the time of year and phase of the construction.
Collection of discharge samples for non-visible pollutant monitoring will be triggered only when any of the following conditions are observed during site inspections conducted prior to or during a rain event.
• Materials or wastes containing potential non-visible pollutants are not stored under watertight conditions. Watertight conditions are defined as (1) storage in a watertight container, (2) storage under a watertight roof or within a building, or (3) protected by temporary cover and containment that prevents stormwater contact and runoff from the storage area.
• Materials or wastes containing potential non-visible pollutants are stored under watertight conditions, but (1) a breach, malfunction, leakage, or spill is observed, (2) the leak or spill is not cleaned up prior to the rain event, and (3) there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system. • A construction activity, including but not limited to those in Section 2.6, with the potential to contribute non-visible pollutants (1) was occurring during or within 24 hours prior to the rain event, (2) BMPs were observed to be breached, malfunctioning, or improperly implemented, and (3) there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system.
• Soil amendments that have the potential to change the chemical properties, engineering properties, or erosion resistance of the soil have been applied, and there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system.
CASQA Traditional SWPPP Template 7-7 March 2024
for the 2022 CGP
• Stormwater runoff from an area contaminated by historical usage of the site has been observed to combine with stormwater runoff from the site, and there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system.
7.7.1.2 Sampling Locations
Sampling locations are based on proximity to planned non-visible pollutant storage, occurrence or use, accessibility for sampling, and personnel safety. As previously noted, all drainage is internal to the project site; there is no direct drainage to the Russian River. Sampling locations, if any are needed, will be based on observations of the locations of discharge, if any.
If needed, one sampling location would be at the upstream part of the Russin River just adjacent to the upstream (north) edge of the project site. This location has been identified for the collection of an uncontaminated sample of runoff as a background sample for comparison with the samples being analyzed for non-visible pollutants. This location was selected such that the sample will not have come in contact with the operations, activities, or areas identified in Section 7.7.1 or with disturbed soils areas.

7.7.2 Sampling and Analysis Plan for pH and Turbidity in Stormwater Runoff Discharges
Sampling and analysis of runoff for pH and turbidity is required for this Risk Level 2 project, in the event that runoff occurs. This Sampling and Analysis Plan describes the strategy for monitoring turbidity and pH levels of stormwater runoff discharges from the project site and run-on that may contribute to an exceedance of a Numeric Action Level (NAL). Samples for pH and turbidity will be collected at all discharge points where stormwater is discharged off-site.
CASQA Traditional SWPPP Template 7-12 March 2024
for the 2022 CGP
7.7.2.1 Sampling Schedule
Stormwater runoff samples shall be collected for pH and turbidity from each day of a qualifying precipitation event that results in a discharge from the project site, in the event that discharge occurs. One sample from each discharge location will be collected each 24-hour period of active discharge during a qualifying precipitation event. Samples should be representative of the discharge flow and characteristics. Run-on samples shall be collected whenever the QSP identifies that run-on has the potential to contribute to an exceedance of a NAL.
7.7.2.2 Sampling Locations
Sampling locations are based on the site runoff discharge locations and locations where run-on enters the site, accessibility for sampling, and personnel safety. As previously noted, all drainage at the project site is internal; there are no direct discharge locations to the Russian River. Therefore, in the unlikely event of a discharge, pH and turbidity sampling locations, if any are needed, will be based on observations of the locations of run-on and run-off discharge, if any.
7.7.2.3 Monitoring Preparation
Turbidity and pH samples will be collected and analyzed by:

• Do not breathe, sneeze, or cough in the direction of an open sample container.
The most important aspect of grab sampling is to collect a sample that represents the entire runoff stream. Typically, samples are collected by dipping the collection container in the runoff flow paths and streams as noted below.
i. For small streams and flow paths, simply dip the bottle facing upstream until full. ii. For larger stream that can be safely accessed, collect a sample in the middle of the flow stream by directly dipping the mouth of the bottle. Once again making sure that the opening of the bottle is facing upstream as to avoid any contamination by the sampler. iii. For larger streams that cannot be safely waded, pole-samplers may be needed to safely access the representative flow.
iv. Avoid collecting samples from ponded, sluggish or stagnant water. v. Avoid collecting samples directly downstream from a bridge as the samples can be affected by the bridge structure or runoff from the road surface.
Note, that depending upon the specific analytical test, some containers may contain preservatives. These containers should never be dipped into the stream but filled indirectly from the collection container.
7.7.7.2 Sample Handling
Turbidity and pH measurements must be conducted immediately. Do not store turbidity or pH samples for later measurement.
Samples for laboratory analysis must be handled as follows. Immediately following sample collection:
• Cap sample containers;
• Complete sample container labels;
• Place sealed containers in a re-sealable storage bag; • Place sample containers into an ice-chilled cooler;
• Document sample information on the Effluent Sampling Field Log Sheet (Appendix O); and
• Complete the CoC.
All samples for laboratory analysis must be maintained between 0-6 degrees Celsius during delivery to the laboratory. Samples must be kept on ice, or refrigerated, from sample collection through delivery to the laboratory. Place samples to be shipped inside coolers with ice. Make sure the sample bottles are well packaged to prevent breakage and secure cooler lids with packaging tape.
Ship samples that will be laboratory analyzed to the analytical laboratory right away. Hold times are measured from the time the sample is collected to the time the sample is analyzed. The 2022 CGP requires that samples be received by the analytical laboratory within 48 hours of the physical sampling (unless required sooner by the analytical laboratory to meet all hold times).

7.7.7.3 Sample Documentation Procedures
All original data documented on sample container identification labels, Effluent Sampling Field Log Sheet (Appendix O), and CoCs shall be recorded using waterproof ink. These shall be considered accountable documents. If an error is made on an accountable document, the individual shall make corrections by lining through the error and entering the correct information. The erroneous information shall not be obliterated. All corrections shall be initialed and dated.
Duplicate samples shall be identified consistent with the numbering system for other samples to prevent the laboratory from identifying duplicate samples. Duplicate samples shall be identified in the Effluent Sampling Field Log Sheet.
Sample documentation procedures include the following:
Sample Bottle Identification Labels: Sampling personnel shall attach an identification label to each sample bottle. Sample identification shall uniquely identify each sample location. (These location identifiers should be listed in the tables in the SWPPP.) Field Log Sheets: Sampling personnel shall complete the Effluent Sampling Field Log Sheet and Receiving Water Sampling Field Log Sheet (Appendix O) for each sampling event, as appropriate.
Chain of Custody: Sampling personnel shall complete the CoC for each sampling event for which samples are collected for laboratory analysis. The sampler will sign the CoC (Appendix O) when the sample(s) is turned over to the testing laboratory or courier.
7.8 Active Treatment System Monitoring
Will an Active Treatment System (ATS) be deployed on the site? ☐ Yes ☒ No
This project does not require a project specific Sampling and Analysis Plan for an ATS because deployment of an ATS is not planned.
7.9 Passive Treatment Monitoring
Will passive treatment technologies be deployed on the site? ☐ Yes ☒ No
This project does not require a project specific Sampling and Analysis Plan for passive treatment because deployment of passive treatment is not planned.
7.10 Watershed Monitoring Option
This project is not participating in a watershed monitoring option.
7.11 Quality Assurance and Quality Control
An effective Quality Assurance and Quality Control (QA/QC) plan shall be implemented as part of the CSMP to ensure that analytical data can be used with confidence. QA/QC procedures to be initiated include the following:
CASQA Traditional SWPPP Template 7-19 March 2024
for the 2022 CGP
• Field logs;
• Clean sampling techniques;
• CoCs;
• QA/QC Samples, if needed; and
• Data verification.
Each of these procedures is discussed in more detail in the following sections.
7.11.1 Field Logs
The purpose of field logs is to record sampling information and field observations during monitoring that may explain any uncharacteristic analytical results. Sampling information to be included in the field log include the date and time of water quality sample collection, sampling personnel, sample container identification numbers, and types of samples that were collected.
Field observations should be noted in the field log for any abnormalities at the sampling location (color, odor, BMPs, etc.). Field measurements for pH and turbidity should also be recorded in the field log. A Visual Inspection Field Log, an Effluent Sampling Field Log Sheet, [and a Receiving Water Sampling Field Log Sheet] are included in Appendix O.
7.11.2 Clean Sampling Techniques
Clean sampling techniques involve the use of certified clean containers for sample collection and clean powder-free nitrile gloves during sample collection and handling. As discussed in Section 7.7.7, adoption of a clean sampling approach will minimize the chance of field contamination and questionable data results.
7.11.3 Chain of Custody
The sample CoC is an important documentation step that tracks samples from collection through analysis to ensure the validity of the sample. Sample CoC procedures include the following:
• Proper labeling of samples;
• Use of CoC forms for all samples; and
• Prompt sample delivery to the analytical laboratory.
Analytical laboratories usually provide CoC forms to be filled out for sample containers. An example CoC is included in Appendix O.
7.11.4 QA/QC Samples
QA/QC samples provide an indication of the accuracy and precision of the sample collection; sample handling; field measurements; and analytical laboratory methods. The following types of QA/QC will be conducted for this project:
☒ Field Duplicates at a frequency of [5 percent or 1 duplicate minimum per sampling event]
(Required for all sampling plans with field measurements or laboratory analysis) ☐ Equipment Blanks at a frequency of [Insert frequency required by method] (Only needed if the equipment used to collect samples could add the pollutants to sample) ☐ Field Blanks at a frequency of [Insert frequency required by method] (Only required if sampling method calls for field blanks)
CASQA Traditional SWPPP Template 7-20 March 2024
for the 2022 CGP
☐ Travel Blanks at a frequency of [One per sampling event] (Required for sampling plans that include VOC laboratory analysis)
7.11.4.1 Field Duplicates
Field duplicates provide verification of laboratory or field analysis and sample collection.
Duplicate samples shall be collected, handled, and analyzed using the same protocols as primary samples. The sample location where field duplicates are collected shall be randomly selected from the discharge locations. Duplicate samples shall be collected immediately after the primary sample has been collected. Duplicate samples must be collected in the same manner and as close in time as possible to the original sample.
7.11.4.2 Equipment Blanks
Equipment blanks provide verification that equipment has not introduced a pollutant into the sample. Equipment blanks are typically collected when:
• New equipment is used;
• Equipment that has been cleaned after use at a contaminated site; • Equipment that is not dedicated for surface water sampling is used; or • Whenever a new lot of filters is used when sampling metals.
7.11.4.3 Field Blanks
Field blanks assess potential sample contamination levels that occur during field sampling activities. De-ionized water field blanks are taken to the field, transferred to the appropriate container, and treated the same as the corresponding sample type during the course of a sampling event.
7.11.4.4 Travel Blanks
Travel blanks assess the potential for cross-contamination of volatile constituents between sample containers during shipment from the field to the laboratory. De-ionized water blanks are taken along for the trip and held unopened in the same cooler with the VOC samples.
7.11.5 Data Verification
After results are received from the analytical laboratory, the QSP or QSP Delegates shall verify the data to ensure that it is complete, accurate, and the appropriate QA/QC requirements were met. Data must be verified as soon as the data reports are received. Data verification shall include:
• Check the CoC and laboratory reports.
Make sure all requested analyses were performed and all samples are accounted for in the reports.
• Check laboratory reports to make sure hold times were met and that the reporting levels meet or are lower than the reporting levels agreed to in the contract. • Check data for outlier values and follow up with the laboratory.
Occasionally typographical errors, unit reporting errors, or incomplete results are reported and should be easily detected. These errors need to be identified, clarified, and corrected quickly by the laboratory. The QSP or QSP Delegates should especially note data that is an order of magnitude or more different than similar locations or is inconsistent with previous data from the same location.
CASQA Traditional SWPPP Template 7-21 March 2024
for the 2022 CGP
• Check laboratory QA/QC results.
EPA establishes QA/QC checks and acceptable criteria for laboratory analyses. These data are typically reported along with the sample results. The QSP or QSP Delegates shall evaluate the reported QA/QC data to check for contamination (method, field, and equipment blanks), precision (laboratory matrix spike duplicates), and accuracy (matrix spikes and laboratory control samples). When QA/QC checks are outside acceptable ranges, the laboratory must flag the data, and usually provides an explanation of the potential impact to the sample results. • Check the data set for outlier values and, accordingly, confirm results and re-analyze samples where appropriate.
Sample re-analysis should only be undertaken when it appears that some part of the QA/QC resulted in a value out of the accepted range. Sample results may not be discounted unless the analytical laboratory identifies the required QA/QC criteria were not met and confirms this in writing.
Field data including inspections and observations must be verified as soon as the field logs are received, typically at the end of the sampling event. Field data verification shall include:
• Check field logs to make sure all required measurements were completed and appropriately documented;
• Check reported values that appear out of the typical range or inconsistent; Follow-up immediately to identify potential reporting or equipment problems, if appropriate, recalibrate equipment after sampling;
• Verify equipment calibrations;
• Review observations noted on the field logs; and
• Review notations of any errors and actions taken to correct the equipment or recording errors.
7.12 Records Retention
All records of stormwater monitoring information and copies of reports (including Annual Reports) must be retained for a period of at least three years from date of submittal or longer if required by the Regional Water Board. Results of visual monitoring, field measurements, and laboratory analyses must be kept in the SWPPP along with CoCs, and other documentation related to the monitoring. Records are to be kept onsite while construction is ongoing. Records to be retained include:
• The date, place, and time of inspections, sampling, visual observations, and/or measurements, including precipitation;
• The individual(s) who performed the inspections, sampling, visual observation, and/or field measurements;
• The date and approximate time of field measurements and laboratory analyses; • The individual(s) who performed the laboratory analyses; • A summary of all analytical results, the method detection limits and reporting limits, and the analytical techniques or methods used;
• Rain gauge readings from site inspections;
• QA/QC records and results;
• Calibration records;
• Visual observation and sample collection exception records; • The records of any corrective actions and follow-up activities that resulted from analytical results, visual observations, or inspections; • [NAL Exceedance Report].

CHAPTER 1
Introduction
This report has been prepared to document the results and conclusions of an aquatic resources delineation field survey conducted for the Ukiah Riverside Park Regeneration Project (Project).
The Project is located in the City of Ukiah near the Russian River (Figure 1). The study area comprises phase 2 of Riverside Park. Phase 1 was constructed in approximately 2011. The study area was once the location of a City wastewater treatment facility, but has not been used for that purpose in decades. On behalf of Melton Design Group and the City of Ukiah, Environmental Science Associates (ESA) investigated the extent of aquatic resources in the study area that potentially meet the criteria for waters of the U.S.
This report documents the boundaries of the aquatic features within the study area using field data and the best professional judgment of ESA investigators. All conclusions presented should be considered preliminary and subject to change pending review and verification by the U.S. Army Corps of Engineers (USACE).
1.1 Purpose
The purpose of this investigation is to describe and delineate all potential wetlands and other waters of the U.S. within the study area that may be subject to Section 404 of the Clean Water Act. Information from this report may be used in preparing permit applications for future actions proposed in the study area.
1.2 Location
The approximately 8.6-acre study area is located at 1151 East Gobbi Street in the City of Ukiah, in Mendocino County. The study area is near phase 1 of Riverside Park, baseball fields, and a BMX track. The study area is on an unsectioned portion of the Ukiah, California U.S. Geological Survey (USGS) 7.5-minute series quadrangle corresponding to Township 15 north, Range 12 west of the Rancho Yokaya land grant. The approximate centroid of the study area is 39º 08′
36.94″ North, 123º 10′ 58.17″ West. Topography is flat except spoils piles and excavations related to the old wastewater treatment plant. Elevation ranges from approximately 570–587 feet.
The study area is in the floodplain of the Russian River (FEMA, 2019). An aerial photograph map of the study area is provided in Figure 2.

CHAPTER 2
Methods
2.1 Pre-field Review
Prior to conducting fieldwork, the following background tasks were performed:
Review of current and historic Ukiah, California U.S. Geologic Survey (USGS) topographic maps (USGS, 2019);
Review of current and historic aerial photography (Google, Inc., 2019); Review of the online soil survey (NRCS, 2019a) for information about soils and geomorphology;
Review of the National Hydric Soils List (NRCS, 2019b) to determine if any soil mapping unit components are considered hydric;
Review of the National Wetlands Inventory (U.S Fish and Wildlife Service [USFWS], 2019); Review of the San Francisco USACE District Navigable Waterways (USACE, 1971); and Review of the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) (FEMA, 2019).
2.2 Field Survey Methods
The fieldwork was conducted by ESA biologists Chuck Hughes and Elizabeth Hill on May 22, 2019. The delineation used the “Routine Determination Method” as described in the 1987 Corps of Engineers Wetland Delineation Manual (Environmental Laboratory, 1987), hereafter called the “1987 Manual.” The 1987 Manual was used in conjunction with the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (USACE, 2008), hereafter called the “Arid West Supplement.” For areas where the 1987 Manual and the Arid West Supplement differ, the Arid West Supplement was followed. In addition, the Guide to Ordinary High Water Mark (OHWM) delineation for non-perennial streams in the western mountains, valleys, and coast region of the United States (USACE, 2014) was used to identify the lateral limits of streams.
The Arid West Supplement is applicable for use at the site because the study area experiences hot, dry summers typical of a Mediterranean climate, and the surrounding landscape in the bottom of the valley is dominated by oaks (USACE, 2008). The study area is very near the boundary between the Arid West Region (LRR C) and the Western Mountains, Valleys, and Coast Region
2. Methods

(LRR A). The Arid West Supplement was used for this delineation based on landscape, site conditions, vegetation, and climate. The Western Mountains, Valleys, and Coast Region OHWM guide was used for delineating the boundaries of other waters because that guide is more applicable than the Arid West OHWM Guide in the region of the study area.
Three positive parameters must normally be present for an area to be considered a wetland: 1) a dominance of wetland vegetation, 2) presence of hydric soils, and 3) presence of wetland hydrology. ESA assessed presence or absence of positive indicators for wetland vegetation, soils, and hydrology per the 1987 Manual and Arid West Supplement. Data points were recorded on Arid West wetland determination data forms (Appendix A).
At each data point, a visual assessment of the plant cover by species was made. Dominant species were assessed using the “50/20” rule per the Arid West Supplement. Plants were identified to species using The Jepson Manual: Vascular Plants of California, second edition (Baldwin et al., 2012). The Arid West 2016 Regional Wetland Plant List (Lichvar et al., 2016) was used to determine the wetland indicator status of all plants. Soils at each data point were characterized by color, texture, organic matter accumulation, and the presence or absence of hydric soil indicators.
Color was described using the Munsell Soil Color Book (Munsell Color, 2015). Presence of wetland hydrology was determined at each data point by presence of one or more of the primary and/or secondary indicators, per the Arid West Supplement.
For “other waters of the U.S.” to be considered jurisdictional, these features must exhibit a defined bed and bank and an OHWM.
2.3 Mapping and Acreage Calculations
All features, including data points, wetland boundaries, and OHWMs were recorded using a Global Positioning System (GPS) unit (Trimble GeoXT) with real-time differential correction and an instrument-rated mapping accuracy of +/- 1 meter. Boundaries of wetlands were demarcated in the field using GPS by walking the margin of the wetland and taking points at set intervals.
In the office, data from data points and wetland/waters boundaries were downloaded from the GPS unit and mapped using GIS software on an overlay of both topography and geo-referenced aerial photography. GPS-determined wetland/waters boundaries and data points were visually confirmed. Acreage of wetland and waters polygons, and the length of linear features were determined using ArcGIS.
2.4 Limitations
No problems or limitations were encountered.

CHAPTER 3
Regulatory Setting
3.1 2015 Clean Water Rule
In 2015, the USACE and the Environmental Protection Agency (EPA) issued the Clean Water Rule detailing the process for determining Clean Water Act (CWA) jurisdiction over waters of the U.S. The rule is currently in effect in California and 21 other states. The 2015 Clean Water Rule includes a detailed process for determining which areas may be subject to jurisdiction under the CWA, and defines features that are and are not waters of the U.S. Some features may need a significant nexus test to determine if they are a waters of the U.S.
The significant nexus test includes consideration of hydrologic and ecologic factors. The significant nexus test would take into account physical indicators of flow (evidence of an ordinary high water mark [OHWM]), if a hydrologic connection to a Traditional Navigable Water (TNW) exists, and if the aquatic functions of the water body have a significant effect (more than speculative or insubstantial) on the chemical, physical, and biological integrity of a TNW. A significant nexus test includes similarly situated waters in the region. The USACE and EPA will apply the significant nexus standard to assess the flow characteristics and functions of a potential WOTUS to determine if it significantly affects the chemical, physical, and biological integrity of the downstream TNW.
2015 Clean Water Rule Summary
The term “waters of the U.S.” is defined at 33 CFR (Code of Federal Regulations) 328.3(a) as:
(1) All waters which are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; (2) All interstate waters, including interstate wetlands; (3) The territorial seas;
(4) All impoundments of waters otherwise identified as waters of the United States under this section; (5) All tributaries, as defined in paragraph (c)(3) of this section, of waters identified in paragraphs (a)(1) through (3) of this section;
(6) All waters adjacent to a water identified in paragraphs (a)(1) through (5) of this section, including wetlands, ponds, lakes, oxbows, impoundments, and similar waters; (7) All waters in paragraphs (a)(7)(i) through (v) of this section where they are determined, on a case-specific basis, to have a significant nexus to a water identified in paragraphs (a)(1) through (3) of this section. The waters identified in each of paragraphs (a)(7)(i) through (v) of this section are similarly situated and shall be combined, for purposes of a significant nexus analysis, in the watershed that drains to the nearest water identified in paragraphs (a)(1) through (3) of this section. Waters identified in this paragraph shall not be combined with waters identified in paragraph (a)(6) of this section when performing a significant nexus analysis. If waters identified in this paragraph are also an adjacent water under paragraph (a)(6), they are an adjacent water and no case-specific significant nexus analysis is required.
(i) Prairie potholes. Prairie potholes are a complex of glacially formed wetlands, usually occurring in depressions that lack permanent natural outlets, located in the upper Midwest. (ii) Carolina bays and Delmarva bays. Carolina bays and Delmarva bays are ponded, depressional wetlands that occur along the Atlantic coastal plain.

Preliminary Subject to Revision
(iii) Pocosins. Pocosins are evergreen shrub and tree dominated wetlands found predominantly along the Central Atlantic coastal plain.
(iv) Western vernal pools. Western vernal pools are seasonal wetlands located in parts of California and associated with topographic depression, soils with poor drainage, mild, wet winters and hot, dry summers. (v) Texas coastal prairie wetlands. Texas coastal prairie wetlands are freshwater wetlands that occur as a mosaic of depressions, ridges, intermound flats, and mima mound wetlands located along the Texas Gulf Coast.
(8) All waters located within the 100-year floodplain of a water identified in paragraphs (a)(1) through (3) of this section and all waters located within 4,000 feet of the high tide line or ordinary high water mark of a water identified in paragraphs (a)(1) through (5) of this section where they are determined on a case-specific basis to have a significant nexus to a water identified in paragraphs (a)(1) through (3) of this section. For waters determined to have a significant nexus, the entire water is a water of the United States if a portion is located within the 100-year floodplain of a water identified in paragraphs (a)(1) through (3) of this section or within 4,000 feet of the high tide line or ordinary high water mark. Waters identified in this paragraph shall not be combined with waters identified in paragraph (a)(6) of this section when performing a significant nexus analysis.
If waters identified in this paragraph are also an adjacent water under paragraph (a)(6), they are an adjacent water and no case-specific significant nexus analysis is required. 33 CFR 328.3(b) says:
The following are not ‘‘waters of the United States’’ even where they otherwise meet the terms of paragraphs (a)(4) through (8) of this section.
(1) Waste treatment systems, including treatment ponds or lagoons designed to meet the requirements of the Clean Water Act.
(2) Prior converted cropland. Notwithstanding the determination of an area’s status as prior converted cropland by any other Federal agency, for the purposes of the Clean Water Act, the final authority regarding Clean Water Act jurisdiction remains with EPA.
(3) The following ditches:
(i) Ditches with ephemeral flow that are not a relocated tributary or excavated in a tributary. (ii) Ditches with intermittent flow that are not a relocated tributary, excavated in a tributary, or drain wetlands. (iii) Ditches that do not flow, either directly or through another water, into a water identified in paragraphs (a)(1) through (3) of this section.
(4) The following features:
(i) Artificially irrigated areas that would revert to dry land should application of water to that area cease; (ii) Artificial, constructed lakes and ponds created in dry land such as farm and stock watering ponds, irrigation ponds, settling basins, fields flooded for rice growing, log cleaning ponds, or cooling ponds; (iii) Artificial reflecting pools or swimming pools created in dry land; (iv) Small ornamental waters created in dry land;
(v) Water-filled depressions created in dry land incidental to mining or construction activity, including pits excavated for obtaining fill, sand, or gravel that fill with water; (vi) Erosional features, including gullies, rills, and other ephemeral features that do not meet the definition of tributary, non-wetland swales, and lawfully constructed grassed waterways; and (vii) Puddles.
(5) Groundwater, including groundwater drained through subsurface drainage systems. (6) Stormwater control features constructed to convey, treat, or store stormwater that are created in dry land. (7) Wastewater recycling structures constructed in dry land; detention and retention basins built for wastewater recycling; groundwater recharge basins; percolation ponds built for wastewater recycling; and water distributary structures built for wastewater recycling.
The following terms are defined in 33 CFR 328.3(c):
(1) Adjacent. The term adjacent means bordering, contiguous, or neighboring a water identified in paragraphs (a)(1) through (5) of this section, including waters separated by constructed dikes or barriers, natural river berms, beach dunes, and the like. For purposes of adjacency, an open water such as a pond or lake includes any wetlands within or abutting its ordinary high water mark. Adjacency is not limited to waters located laterally to a water identified in paragraphs (a)(1) through (5) of this section. Adjacent waters also include all waters that connect
3. Regulatory Setting
Ukiah Riverside Park Regeneration Project 11 ESA / 181242 Aquatic Resources Delineation Report July 2019
Preliminary Subject to Revision
segments of a water identified in paragraphs (a)(1) through (5) or are located at the head of a water identified in paragraphs (a)(1) through (5) of this section and are bordering, contiguous, or neighboring such water. Waters being used for established normal farming, ranching, and silviculture activities (33 U.S.C. 1344(f)) are not adjacent.
(2) Neighboring. The term neighboring means:
(i) All waters located within 100 feet of the ordinary high water mark of a water identified in paragraphs (a)(1) through (5) of this section. The entire water is neighboring if a portion is located within 100 feet of the ordinary high water mark;
(ii) All waters located within the 100-year floodplain of a water identified in paragraphs (a)(1) through (5) of this section and not more than 1,500 feet from the ordinary high water mark of such water. The entire water is neighboring if a portion is located within 1,500 feet of the ordinary high water mark and within the 100- year floodplain;
(iii) All waters located within 1,500 feet of the high tide line of a water identified in paragraphs (a)(1) or (a)(3) of this section, and all waters within 1,500 feet of the ordinary high water mark of the Great Lakes. The entire water is neighboring if a portion is located within 1,500 feet of the high tide line or within 1,500 feet of the ordinary high water mark of the Great Lakes.
(3) Tributary and tributaries. The terms tributary and tributaries each mean a water that contributes flow, either directly or through another water (including an impoundment identified in paragraph (a)(4) of this section), to a water identified in paragraphs (a)(1) through (3) of this section that is characterized by the presence of the physical indicators of a bed and banks and an ordinary high water mark. These physical indicators demonstrate there is volume, frequency, and duration of flow sufficient to create a bed and banks and an ordinary high water mark, and thus to qualify as a tributary. A tributary can be a natural, man-altered, or man-made water and includes waters such as rivers, streams, canals, and ditches not excluded under paragraph (b) of this section. A water that otherwise qualifies as a tributary under this definition does not lose its status as a tributary if, for any length, there are one or more constructed breaks (such as bridges, culverts, pipes, or dams), or one or more natural breaks (such as wetlands along the run of a stream, debris piles, boulder fields, or a stream that flows underground) so long as a bed and banks and an ordinary high water mark can be identified upstream of the break. A water that otherwise qualifies as a tributary under this definition does not lose its status as a tributary if it contributes flow through a water of the United States that does not meet the definition of tributary or through a non-jurisdictional water to a water identified in paragraphs (a)(1) through (3) of this section. (4) Wetlands. The term wetlands means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.
(5) Significant nexus. The term significant nexus means that a water, including wetlands, either alone or in combination with other similarly situated waters in the region, significantly affects the chemical, physical, or biological integrity of a water identified in paragraphs (a)(1) through (3) of this section. The term ‘‘in the region’’ means the watershed that drains to the nearest water identified in paragraphs (a)(1) through (3) of this section. For an effect to be significant, it must be more than speculative or insubstantial. Waters are similarly situated when they function alike and are sufficiently close to function together in affecting downstream waters.
For purposes of determining whether or not a water has a significant nexus, the water’s effect on downstream paragraph (a)(1) through (3) waters shall be assessed by evaluating the aquatic functions identified in paragraphs (c)(5)(i) through (ix) of this section. A water has a significant nexus when any single function or combination of functions performed by the water, alone or together with similarly situated waters in the region, contributes significantly to the chemical, physical, or biological integrity of the nearest water identified in paragraphs (a)(1) through (3) of this section. Functions relevant to the significant nexus evaluation are the following:
(i) Sediment trapping,
(ii) Nutrient recycling,
(iii) Pollutant trapping, transformation, filtering, and transport, (iv) Retention and attenuation of flood waters,
(v) Runoff storage,
(vi) Contribution of flow,
(vii) Export of organic matter,
(viii)Export of food resources, and
(ix) Provision of life cycle dependent aquatic habitat (such as foraging, feeding, nesting, breeding, spawning, or use as a nursery area) for species located in a water identified in paragraphs (a)(1) through (3) of this section.
(6) Ordinary high water mark. The term ordinary high water mark means that line on the shore established by the fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank,
3. Regulatory Setting
Ukiah Riverside Park Regeneration Project 12 ESA / 181242 Aquatic Resources Delineation Report July 2019
Preliminary Subject to Revision
shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas. (7) High tide line. The term high tide line means the line of intersection of the land with the water’s surface at the maximum height reached by a rising tide. The high tide line may be determined, in the absence of actual data, by a line of oil or scum along shore objects, a more or less continuous deposit of fine shell or debris on the foreshore or berm, other physical markings or characteristics, vegetation lines, tidal gages, or other suitable means that delineate the general height reached by a rising tide. The line encompasses spring high tides and other high tides that occur with periodic frequency but does not include storm surges in which there is a departure from the normal or predicted reach of the tide due to the piling up of water against a coast by strong winds such as those accompanying a hurricane or other intense storm.
The limits of jurisdiction are identified in 33 CFR 328.4 as:
(a) Territorial Seas. The limit of jurisdiction in the territorial seas is measured from the baseline in a seaward direction a distance of three nautical miles. (See 33 CFR 329.12) (b) Tidal Waters of the United States. The landward limits of jurisdiction in tidal waters:
(1) Extends to the high tide line, or
(2) When adjacent non-tidal waters of the United States are present, the jurisdiction extends to the limits identified in paragraph (c) of this section.
(c) Non-Tidal Waters of the United States. The limits of jurisdiction in non-tidal waters:
(1) In the absence of adjacent wetlands, the jurisdiction extends to the ordinary high water mark, or (2) When adjacent wetlands are present, the jurisdiction extends beyond the ordinary high water mark to the limit of the adjacent wetlands.
(3) When the water of the United States consists only of wetlands the jurisdiction extends to the limit of the wetland.
3.2 Traditional Navigable Water
Navigable waters of the United States are defined in 33 CFR § 329.4 as “…those waters that are subject to the ebb and flow of the tide and/or are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. A determination of navigability, once made, applies laterally over the entire surface of the waterbody, and is not extinguished by later actions or events which impede or destroy navigable capacity.” Traditional navigable waters include all of the “navigable waters of the United States” as defined in 33 CFR § Part 329.4 as well as by numerous decision of the federal courts; those water bodies the USACE has determined are a navigable water of the U.S. pursuant to 33. CFR § 329.14; plus all other waters that are navigable-in-fact. The definition of “navigable-in-fact” comes from a long line of court cases originating with Daniel Ball, 77 U.S. 557 (1870).
3.3 Ephemeral, Intermittent, and Perennial Streams
An ephemeral stream has flowing water only during, and for a short duration after, precipitation events in a typical year. Ephemeral stream beds are located above the water table year-round.
Groundwater is not a source of water for the stream. Runoff from rainfall is the primary source of water for stream flow. An intermittent stream has flowing water during certain times of the year, when groundwater provides water for stream flow. During dry periods, intermittent streams may not have flowing water. Runoff from rainfall is a supplemental source of water for stream flow. A perennial stream has flowing water year-round during a typical year (82 Federal Register 1860).

CHAPTER 4
Setting
4.1 Study Area
The study area is in a valley of the Russian River, in the inner North Coast Range. The Russian River is approximately 150 feet east of the study area. There is a corridor of riparian vegetation along the river outside the study area. The study area is located on a flood terrace of the river.
Most of the terrace is used for agriculture, primarily vineyards and pear orchards. The natural vegetation is valley oak woodland.
The study area is at the site of the former City wastewater treatment facility. The former treatment facility is no longer present and was likely removed between 1958 and 1975 (USGS, 2019). Other portions of the former treatment facility are now used for baseball fields, a BMX track, and phase 1 of Ukiah Riverside Park. The study area has experienced substantial ground disturbance in the past as a result of the former treatment facility. Topography is mostly level except for artificial excavations and spoils piles.
The climate in the region consists of cool, wet winters and hot, dry summers. The mean annual precipitation in Ukiah is 37.35 inches and mean annual temperatures range from an average maximum temperature of 73.5 degrees Fahrenheit to an average minimum temperature of 43.6 degrees Fahrenheit (Western Regional Climate Center, 2019; NWSFO, 2019). Precipitation from July 1, 2018 through May 22, 2019 totaled 43.67 inches, which is 119% of the average annual rainfall for that period (NWSFO, 2019). Ukiah received over three inches of precipitation in the week preceding the field work (NWSFO, 2019).
4.2 Soils
The soil map (Figure 3) indicates two soil map units in the study area (NRCS, 2019a). A brief description of each primary soil within each map unit is provided below. All colors refer to moist soil. Both soil map units are listed as hydric where the necessary landform occurs (flood-plains; NRCS, 2019b).
Russian loam, 0–2% slopes. Russian soils formed in alluvium from sedimentary rocks and occur on flood plains and low stream terraces. They are well-drained, with moderate permeability and slow runoff, with occasional flooding. A typical profile of Russian loam has:
0–38 inches Very dark grayish brown (10YR 3/2) neutral loam. 38–65 inches Very dark grayish brown (10YR 3/2) neutral very fine sandy loam.

Preliminary Subject to Revision
Xerofluvents, 0–2% slopes. These soils are on flood plains along rivers or streams or on alluvial fans with a Mediterranean (xeric) moisture regime. Flooding may occur in winter. The vegetation on xerofluvents is commonly mixed forest or grass and shrubs (NRCS 1999).
4.3 Hydrology
The entire study area is in the watershed of the upper Russian River (HUC 1801011004). As discussed previously, the study area is located within the floodplain of the river, and the river is approximately 150 feet east of the study area. There are no traditional navigable waters in or near the study area. The lowest reach of the Russian River is considered a traditional navigable water from Vacation Beach approximately 13.6 miles downstream to the mouth of the river (USACE, 1971). The study area experiences flooding from the nearby Russian River during times of high water.
4.4 Vegetation
Plant communities are assemblages of plant species that occur together in the same area, and are defined by species composition and relative abundance. The entire study area has experienced substantial soil disturbance in the past and vegetation is mostly dominated by nonnative ruderal species. The northern end of the study area contains old spoils piles of asphalt that are covered largely with nonnative invasive Himalayan blackberry (Rubus armeniacus) with some native shrubs including coyote brush (Baccharis pilularis) and blue elderberry (Sambucus nigra ssp. caerulea). The southern end of the study area is dominated by nonnative annual grasses including wild oat (Avena fatua), rye grass (Festuca perennis), and bromes (Bromus spp.). Vegetation in seasonal wetlands is described in Chapter 5.1. A list of plant species recorded at data points is in Appendix B. Representative photographs of the study area are in Appendix C.

5.1 Aquatic Resources
The aquatic resources delineation identified 0.178 acre of aquatic resources within the study area, consisting of two seasonal wetlands. Aquatic resources were classified using the Classification of Wetlands and Deepwater Habitats of the United States (“Cowardin Classification”) (FGDC, 2013). Details of the wetlands are provided in Table 1 and described below. Figure 4 shows the location and extent of the wetlands. The Aquatic Resources Spreadsheet is in Appendix D.

5.1.1 Wetlands
Seasonal Wetland 1
Seasonal wetland (SW) 1 is in the bottom of an artificially excavated pit (Appendix C, Photo 2).
During the time of the survey, SW-1 had hydrophytic vegetation dominated by rye grass (Festuca perennis; FAC) and dock (Rumex sp.; at least FACW). A few willows (Salix sp.) and cottonwoods (Populus fremontii ssp. fremontii) grow along the margin of SW-1. Soils were clearly disturbed from previous activities in the study area. Nevertheless, a horizon at six inches met the redox dark surface indicator. The soil was saturated one inch below the surface at data point 1, and a few other areas within SW-1 had surface water ponded to a depth of up to a few inches.

5. Results
Ukiah Riverside Park Regeneration Project 18 ESA / 181242 Aquatic Resources Delineation Report July 2019
Preliminary Subject to Revision
There are two sources of hydrology for SW-1. The first is surface water runoff from uplands that collects in the bottom of the pit. The second is from flood events of the Russian River. When the water surface elevation of the river reaches approximately 589 feet, water will flow through an eroded gully, away from the river, and into the pit. The bottom of the pit is approximately 574 feet in elevation. The sides of the gully are eroding into an old dirt road (Appendix C, photo 5), and sediment consisting of gravel and sand is splayed into the bottom of the pit. There is no splay of sediment on the river-side of the gully. There is no clear, natural line on the side of the gully indicating an ordinary high water mark. Water will only flow through the gully during flood events. In years in which the river reaches a sufficient flood elevation, SW-1 may be inundated to a depth and for a duration much longer than in other years where upland precipitation runoff is the sole source of hydrology. The base flood elevation (1% chance of being equaled or exceeded in a given year) is approximately 593.5 feet (Appendix E).
Seasonal Wetland 2
SW-2 is in the bottom of an artificially excavated ditch (Appendix C, photo 7). The ditch begins at a culvert outfall that discharges stormwater during rainfall events. The ditch outfalls into the Russian River, although the ditch loses a distinctive bottom and banks near the River. There is no indication from historic topographic maps that the ditch is a relocated tributary (USGS, 2019).
The bottom of the ditch is not uniformly sloped. The western end of the ditch does not fully drain and may retain water up to several inches deep. During the survey, SW-2 had hydrophytic vegetation and soils similar to SW-1. Hydrology indicators were fine sediments on the bottom few inches of plant stems and the FAC-neutral test.
5.2 Clean Water Rule Analysis
Table 2 summarizes the application of the clean water rule to the aquatic resources in the study area.
5.2.1 Seasonal Wetland 1
The pit containing SW-1 was dug for the purpose of gravel extraction. While the pit is located at the former wastewater treatment facility that once operated in the study area, it was dug as a source of gravel. The City of Ukiah noted in a 1999 memorandum (Appendix F) that a longtime City Employee indicated the pit “was a naturally occurring gravel deposit that the City excavated.”
33 CFR 328.3(b)(4)(v) excludes pits excavated in dry land for obtaining gravel that fill with water as waters of the U.S. Such features are not waters of the U.S., even where they include wetlands that would otherwise meet the terms of paragraphs (a)(4) through (a)(8). The pit was dug in the floodplain of the Russian River, but the area surrounding the pit is uplands. The pit was dug in dry land, for the purpose of gravel extraction, and hence is not a waters of the U.S.

Preliminary Subject to Revision
5.2.2 Seasonal Wetland 2
SW-2 is in the bottom of an excavated ditch. The ditch is not a relocated tributary or excavated in a tributary. There are no tributaries shown in the study area on any of the USGS (2019) topographic maps, including the oldest one reviewed from 1957. The ditch flows ephemerally during precipitation events. The ditch receives flow from the outfall of a City stormwater culvert and conveys stormwater from the culvert outfall to the Russian River. 33 CFR 328.3(b)(3)(i) excludes as waters of the U.S. ditches with ephemeral flow that are not a relocated tributary or excavated in a tributary. The ditch meets this definition. 33 CFR 328.3(b)(6) excludes as waters of the U.S. stormwater control features constructed to convey stormwater that are created in dry land. The ditch also meets this definition. The ditch was dug in the floodplain of the Russian River, but the area surrounding the ditch is uplands. Features that meet the definition of sections (b)(3) and (b)(6) are not waters of the U.S., even where they include wetlands that would otherwise meet the terms of paragraphs (a)(4) through (a)(8).
