GHD | City of Fortuna | 12577017 | Wetland Delineation 4 All artificial wetlands that are less than an acre in size and do not satisfy the criteria set forth in 2, 3.a, 3.b, or 3.c are not waters of the state. If an aquatic feature meets the wetland definition, the burden is on the applicant to demonstrate that the wetland is not a water of the state” (SWRCB, 2021).
The April 2020 Implementation Guidance for the State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State further clarifies as follows:
Human activity can cause changes to the surrounding landscape (e.g., grading activities, road construction, direct hydromodification) such that wetlands form where wetlands did not previously exist. Where such artificial wetlands are now a relatively permanent part of the natural landscape, and are not subject to ongoing operation and maintenance, they are waters of the state. By requiring that the wetlands are relatively permanent, the framework excludes wetlands that are temporary or transitory. That they are part of the natural landscape also indicates the relative permanence of the wetlands and suggests that the wetland is selfsustaining without ongoing operation and maintenance activities, and provides similar ecosystem services as natural wetlands. By way of example, this category of wetlands includes situations where water flow is permanently redirected as the result of human activity, such as grading in another area, such that new wetlands form in areas that were previously dry. These wetlands may not be natural wetlands because they result from human activity and they were not formed by modifying a water of the state (rather they were an indirect result), but nevertheless they take on the function of natural wetlands such that they should be considered waters of the state. This category would not include artificial wetlands constructed for specific purposes listed in section II.3.d because the construction of the artificial wetlands would be too recent to be deemed “historic” and the artificial wetland would likely require ongoing maintenance such that they would not be deemed “relatively permanent,” and/or the artificial wetland is not part of the “natural landscape” (SWRCB, 2020).
1.4.3 Local Jurisdiction
The PSB is entirely in the jurisdiction of the City of Fortuna General Plan 2030, adopted 2010.
City of Fortuna General Plan 2030
NCR‐2.10 Wetland Identification and Protection.
In considering new development projects, the City shall conduct an initial screening, as described in Policy NCR‐2.6 in order to determine whether the proposal would have the potential to impact wetlands. If the initial screening indicates the potential presence of wetlands, a wetland assessment/ delineation shall be prepared to determine the presence of jurisdictional wetlands. The assessment/delineation, with proposed mitigation, shall be submitted to the City, and appropriate state (CDF&G) and federal (USCOE) agencies for concurrence prior to permitting. Mitigation may include, but may not be limited to, avoidance, minimization of impacts, restoration, off‐site replacement, and/or the use of buffers.
2. Methodology
2.1 Wetland Delineation Approach
GHD environmental scientists conducted the wetland delineation on January 26, 2023. To define a wetland, the USACE requires that vegetation, soil, and hydrology (three-parameters) all show wetland attributes (USACE 1987; USACE 2010). The wetland delineation used USACE criteria from the Regional Supplement to the Corps of Engineers GHD | City of Fortuna | 12577017 | Wetland Delineation 5 Wetland Delineation Manual: Western Mountains, Valleys and Coast Region (USACE 2010). The current standard field forms provided by the USACE (2010) were used to collect vegetation, soils, and hydrology data (Appendix B).
In potential wetland areas, vegetation, soil, and hydrology data were collected in locations most likely to meet all three parameters; i.e. the lowest point of a drainage or locations with hydrophytic vegetation. Data collection points were mapped in the field with an Eos Arrow 100 Submeter Global Positioning System (GPS) Receiver with Global Navigation Satellite System (GNSS) and an iPad running ArcGIS Collector software.
Each data collection point was designated with “Up” and a number (e.g., Up1, Up2). The sampling points were completed to confirm and document the absence of at least one wetland indicator (soils, hydrology, and/or vegetation).
Appendix B contains all datasheets recorded during the delineation.
2.2 Vegetation
Vegetation data collection consisted of listing the dominant species in the herbaceous, shrub, vine, and tree layer within a standard-sized plot determined by the strata layer. Nomenclature follows The Jepson Manual (Baldwin et al. 2012), which was cross-walked to federal standard nomenclature to identify the wetland indicator status. The species’ wetland indicator status for the Western Mountains, Valleys, and Coast Region was noted in the respective column, using the standard reference: National USACE 2020 Wetland Plant List (USACE 2020a). This list classifies species based on the probability that they are found in wetlands (USACE 1987) as follows:
• Obligate (OBL): almost always in wetlands (99% probability) • Facultative Wetland (FACW): usually occurring in wetlands (67% to 99% probability) • Facultative (FAC): commonly occurring in wetlands and uplands (34% to 66% probability of occurring in wetlands)
• Facultative Upland (FACU): usually occurring in uplands (1% to 33% probability of occurring in wetlands) • Upland (UPL): upland obligate, rarely in wetlands (1% in wetlands) Species that do not appear on the list are considered to be in the upland category (USACE 2010). Standard procedures for documenting hydrophytic vegetation indicators were used per the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (USACE 2010).
A complete list of plants documented at the site with respective wetland indicator status is included as Appendix C. photographs have been included as Appendix D. The separate Biological Technical Memorandum documents the location and extent of mapped vegetation alliances and Sensitive Natural Communities within the Project Area (GHD 2023).
2.3 Soils
Hydric soils were defined based on the Regional Supplement to the Corps of Engineers Wetland Delineation Manual:
Western Mountains, Valleys, and Coast Region (Version 2.0) (USACE 2010) procedures in combination with the Natural Resources Conservation Service’s (NRCS) definitions presented in Field Indicators of Hydric Soils in the United States (USDA 2018). Soil pits were dug to an approximate depth of 14 inches. Data on soil color, texture, and redoximorphic features were recorded. Any observed redoximorphic features (iron concentrations) were noted along with their percentage within the soil matrix, and care was taken to distinguish chromas of 1 and 2 indicative of an irondepleted soil within 12 inches of the soil surface (USACE 2010; USDA 2018).
The Munsell Soil Color Book (COLOR, M. 2000) was used to describe the soil colors for the entire depth of the test pit.
Moist, natural soil aggregate (ped) surfaces, which had not been crushed, were used to determine the soil’s color.
Soils with low chroma were verified as being hydric or upland with Field Indicators of Hydric Soils in the United States (Version 8.2, 2018).

2.4 Hydrology
Aerial photography and the National Wetland Inventory Mapper were referenced before conducting fieldwork (Appendix A, Figure 3) (NWI 2023). The flood hazard map is also included in Appendix A, Figure 4 (FEMA 2023).
Wetland hydrology indicators, such as drainage patterns, material deposits, soil saturation, high water table, or surface water presence, were recorded in the field. There are no streams or previously mapped aquatic resources within the PSB.
3. Existing Conditions
3.1 Landscape Setting
The PSB is in the Strongs Creek-Eel River watershed which is in the Klamath-Northern California Coastal hydrologic unit. The PSB includes both the northbound and southbound off and on-ramps around the 12th Street interchange on Highway 101 (Appendix A, Figure 2). Elevations in the PSB range from 42 to 50 feet above sea level.
The vegetation around the interchange is dominated by non-native annual grasses and forbs, landscaped trees including Monterrey pine x knobcone pine hybrids (Pinus attenuata x Pinus radiata) and redwood (Sequoia sempervirens), small stands of willows (Salix spp.), alders (Alnus rubra), and blackberries (Rubus spp.) and large stands of California blackberry (Rubus ursinus).
3.2 Climate Conditions
GHD delineated wetlands within the PSB on January 26, 2023. Rainfall for the 2023 water year at the Scotia, California weather station approximately eight miles southeast of the PSB totaled 32.43 inches, which was well above average (25.88 inches) for the end of January (NOAA 2023). Mean annual precipitation in the Project Area ranges from 44 to 48 inches (USDA 2023). A WETS table showing climate data for Scotia, California (8 miles southeast of the PSB) is provided in Appendix E.
3.3 Existing Soils Information
The U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) identifies two soil units within the Project Area (Appendix A, Figure 5 and NRCS report in Appendix F). A brief map unit description, as generated by the NRCS, is provided for each soil unit below (NRCS 2023). Although NRCS soil mapping is informative, the scale is generally too broad to definitively characterize potential wetlands. Please see the full report included as Appendix F for complete details.
Urban land-Friendlycity association, 0 to 2 percent slopes The Urban land-Friendlycity association, 0 to 2 percent slopes map unit composition contains: 65% Urban land, residential, 25% Friendlycity and similar soils, and 10% minor components (consisting of 4% Canalschool, 3% Ferndale, and 3% Carlotta). This soil type comprises 93.5% of the PSB (Appendix A, Figure 5 and Appendix F).
The Urban land-Friendlycity association can be found on alluvial fans and terraces, and the parent material is alluvium derived from metamorphic and sedimentary rock. The Urban land-Friendlycity association consists of silt loam in the top horizon (0-6 inches) above silty clay loam (6-55 inches), and loam on the bottom horizon (55-67 inches). The Urban land-Friendlycity association has a land capability classification (LCC) of 2s without irrigation and 1 with irrigation and is not rated as a hydric soil. The Urban land-Friendlycity association is moderately well drained, and the depth to water table is about 20 to 39 inches.
GHD | City of Fortuna | 12577017 | Wetland Delineation 7 Ferndale, 0 to 2 percent slopes
The Ferndale, 0 to 2 percent slopes map unit composition contains: 85% Ferndale and similar soils, and 15% minor components (consisting of 4% Swainslough, 4% Worswick, 3% Russ, 2% Arlynda, and 2% Madriver). This soil type comprises 6.5% of the PSB and is located on the northern edge of the PSB (Appendix A, Figure 5 and Appendix F).
Ferndale soils can be found on flood-plain steps, and the parent material is alluvium derived from mixed sources.
Ferndale soils consists of silt loam in all horizons (0-50 inches) except for find sandy loam on the bottom horizon (50- 60 inches). Ferndale soils has an LCC of 2s without irrigation and 1 with irrigation and is not rated as a hydric soil.
Ferndale soils are well drained, and the depth to water table is 48 to 60 inches.
3.4 Known Hydrological Resources
The PSB is between the perennial Strong’s Creek to the south, and the perennial Rohner Creek to the north (Appendix A, Figure 3, NWI 2023). Neither creek is within the PSB and no other known hydrological resources are present.
4. Results
The PSB does not contain any wetlands meeting all three parameters for hydrophytic vegetation, hydrology, and hydric soils (Appendix A, Figure 3; Appendix B, Appendix D). Soil pits data was collected from seven locations with drainage or vegetation indicators. However, all seven locations qualified as uplands.
5. Conclusions
The wetland delineation for the Fortuna 12th Street Interchange Project determined that no wetlands or aquatic resources are present, using methods and indicators outlined in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys and Coast Region (USACE 2010). Given that precipitation at the time of the delineation was well above normal, standing water and other wetland indicators would have been apparent. Data forms are attached showing sample plot data collected in seven upland locations (Appendix B).

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

Soil surveys are made to provide information about the soils and miscellaneous areas in a specific area. They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity.
Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape.
Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research.
The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded.
These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties.
While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management.
Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and Custom Soil Resource Report
6 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, Custom Soil Resource Report
11 onsite investigation is needed to define and locate the soils and miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.
