1 EXECUTIVE SUMMARY
At the request of Raney Planning & Management, Inc (Applicant), Huffman‐Broadway Group, Inc. (HBG) conducted an Aquatic Resources Delineation (ARD) within the Badger Park Project development area in Healdsburg, California (ARD “Review Area”). The purpose of this ARD is to provide technical information for the Corps to determine if the aquatic resources delineated within the Review Area are potentially subject to: (1) US Army Corps of Engineers (Corps) and US Environmental Protection Agency (US EPA) jurisdiction under Section 404 of the Clean Water Act (CWA) (33 U.S.C. 1344) based on consistency with the August 29, 2023 WOTUS Rule, and (2) Corps jurisdiction under the Rivers and Harbors Act of 1899 (RHA) (33 U.S.C. Sec. 401 et seq.).

Data collection, analysis, identification, and delineation of aquatic resources potentially subject to CWA was conducted consistent with the August 29, 2023 WOTUS Rule and supporting Corps and US EPA guidance document including the Corps’ 1987 Wetlands Delineation Manual (Corps Delineation Manual), the Corps’ 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual:

Arid West Region (Version 2.0) (Regional Supplement), and the OHWM Field Guide (Lichvar and McColley 2008), and the National Ordinary High Water Mark Field Delineation Manual for Rivers and Streams: Interim Version (Gabrielle, et al., 2022).

Aquatic resources in the form of wetlands and tributaries (streams with an OHWM) were found within the Review Area. Appendix A, Figure 6 shows the aquatic resources identified and delineated which are potentially subject to Corps and USEPA Section 404 CWA jurisdiction.

The portion of the Russian River that is within and adjacent to the Review Area has been determined not to be subject to RHA jurisdiction by the San Francisco District.

1.1 Background
At the request of Raney Planning & Management, Inc. (Applicant), Huffman‐Broadway Group, Inc. (HBG) conducted an Aquatic Resources Delineation (ARD) within the Badger Park Project development area in Healdsburg, California (ARD “Review Area”). The purpose of this ARD is to provide technical information for the Corps to determine if the aquatic resources delineated within the Review Area are potentially subject to: (1) US Army Corps of Engineers (Corps) and US Environmental Protection Agency (US EPA) jurisdiction under Section 404 of the Clean Water Act (CWA) (33 U.S.C. 1344) based on consistency with the August 29, 2023 WOTUS Rule, and (2) Corps jurisdiction under the Rivers and Harbors Act of 1899 (RHA) (33 U.S.C. Sec. 401 et seq.).

1.2 Review Area Location
The Review Area for the ARD is east of Highway 101 (Appendix A, Figures 1 - 3). The northeastern portion of the Review Area is accessible from Heron Drive. The approximate center point of the 18.78- acre Review Area is Latitude 38.609038° north and Longitude 122.857856° west.

1.5 EnvironmentalSetting
This section presents background environmental information on the Review Area from published sources, which is augmented with observations made during the initial site reconnaissance.

1.5.1 Land Use
The Review Area consists of a public park and undeveloped lands (Appendix A, Figure 3).

1.5.2 Topography
The topographic relief on the majority of the Review Area is relatively flat with gently rolling landscapes, ranging between 78 and 100 feet MSL1 with slopes ranging between 0 and 5 percent (USGS 1 MSL = Mean Sea Level.

Item 7.c
509 of 697

1.0 Introduction
3 7.5' Healdsburg Quadrangle).

1.5.3 Geology
The Review Area consists of a mosaic of alluvial fans and terraces derived from alluvium derived from sedimentary rock; and flood plains composed of sandy and gravelly alluvium (NRCS 2023).

1.5.4 Vegetation
Valley Foothill Riparian
Structure. Mature riparian ecosystems include canopy trees with a canopy cover of 20 to 80 percent, a subcanopy tree layer and an understory shrub layer. Generally, the understory is impenetrable and includes fallen limbs and other debris. In the CDFW List of Natural Communities the area mapped as Valley Foothill Riparian within the floodplain of the Russian River and dominated by willow trees would be referred to as North Coast Riparian Scrub.

Composition. The Valley Foothill Riparian habitat on the Project Site consists of the forested area between the developed portion of Badger Park and the Russian River. Dominant species in the canopy layer of the on-site riparian habitat include arroyo willow (Salix lasiolepis), black cottonwood (Populus trichocarpa), box elder (Acer negundo), and a lesser number of other native trees such as California bay (Umbellularia californica), Coast live oak (Quercus agrifolia), and blue elderberry (Sambucus cerulea).

The canopy layer of this habitat on the project site also includes a considerable number of non-native tree privet (Ligustrum lucidum) and a single Canary Island palm (Phoenix canariensis).

The understory of the extensive Valley Foothill Riparian habitat within the park is thick growth of mostly non-native plants that includes species such as greater periwinkle (Vinca major), English ivy (Hedera helix), poison hemlock (Conium maculatum), sweet fennel (Foeniculum vulgare), giant reed (Arundo donax), blue lilly (Agapanthus praecox), purple dead nettle (Lamium purpureum), curly dock (Rumex crispus), and sour grass (Oxalis pes-caprae), but also native species such as California blackberry (Rubus ursinus), common bedstraw (Gallium aparine), California bee plant (Scrophularia californica), and water sedge (Carex aquatilis). Plant species growing along the edge of the riparian habitat closest to the mowed play fields included fruit trees (Prunus sp.), tree privet, French broom (Genista monspessulana), California blackberry, and lemon balm (Melissa officinalis).

An unnamed creek runs along the northern border of Badger Park (between Badger Park and Heron Drive), enters the site near the northwest corner of the site, and traverses south through the Coastal Oak Woodland and Valley Foothill Riparian areas of the site before emptying into the Russian River near a large clump of arroyo willows. The tree canopy within and along the banks of this stream is mainly arroyo willow, tree privet, blue elderberry, Coast live oak, a few valley oak (Quercus lobata), and an understory consisting mainly of California blackberry.

Coastal Oak Woodland
Structure. The overstory of Coastal Oak Woodlands consists of deciduous and evergreen hardwoods (mostly oaks), sometimes mixed with scattered conifers. In mesic sites, the trees are dense and form a closed canopy. In drier sites, the trees are widely spaced, forming an open woodland or savannah. The understory is equally variable. In some instances, it is composed of shrubs from adjacent chaparral or Item 7.c
510 of 697

1.0 Introduction
4 coastal scrub which forms a dense, almost impenetrable, understory. More commonly, shrubs are scattered under and between trees. Where trees form a closed canopy, the understory varies from a lush cover of shade-tolerant shrubs, ferns, and herbs to sparse cover with a thick carpet of litter. When trees are scattered and form an open woodland, the understory is grassland, sometimes with scattered shrubs. The interrelationships of slope, soil, precipitation, moisture availability, and air temperature cause variations in structure of Coastal Oak Woodlands. These factors vary along the latitudinal, longitudinal and elevational gradients over which Coastal Oak Woodlands are found.

Composition. The Coastal Oak Woodland on the Project Site is continuous with the Valley Foothill Riparian habitat but is found further inland from the Russian River. Tree canopy composition of Coastal Oak Woodlands on the Project Site is dominated by Coast live oak (Quercus agrifolia), with several California buckeye (Aesculus californica), and a large numbers of non-native tree privet are also present. Typical understory plants in the onsite Coast Live Oak Woodlands include California blackberry, English ivy, elderberries, poison oak (Toxicodendron diversiloba), and multiflora rose (Rosa multiflora), among others.

Urban
Structure. The structure of urban vegetation varies, with five types of vegetative structure defined:
tree grove, street strip, shade tree/lawn, lawn, and shrub cover. Tree groves, common in city parks, green belts, and cemeteries, vary in height, tree spacing, crown shape, and understory conditions, depending upon the species planted and the planting design. The juxtaposition of urban vegetation types within cities produces a rich mosaic with considerable edge areas. The overall mosaic may be more valuable as wildlife habitat than the individual units in that mosaic.

Composition. The Urban habitat on the Project Site consists primarily of the developed portions of the Project Site (including the play fields, tot-lot, parking lot and other amenities where some remnant native trees may be present but where most vegetation consists of non-native species or plants used in landscaping), the community garden, and an adjacent small field of non-native grasses and herbaceous species that is considered a ruderal habitat. The composition of the vegetation within the Urban habitat is discussed below, however, note that investigators did not attempt to catalog vegetation within the community garden as the Project proposes no change to the community garden.

The area of the parking lot is mostly paved, but trees are planted within islands and medians consisting mostly of common hackberry (Celtis occidentalis) and with Empress tree (Paulownia tomentosa) planted along the edge of the dog park. Several Coast redwood trees (Sequoia sempervirens) have been planted in the southeast corner of the parking lot. The tot-lot was apparently constructed in a small area of native Valley oaks as tree canopy in this area consists of several remnant valley oak trees.

Other landscaping in this area includes attractive species such as Chinese fringe flower (Loropetalium chinesnse). The Urban habitat also includes the grassy fields that are mowed and used as play fields and the dog park. These areas were freshly mowed at the time of the field reviews, but grasses and herbaceous plants identifiable along the edges of these areas revealed that vegetation is non-native grass species such as wild oat (Avena fatua), ripgut brome (Bromus diandrus), foxtail barley (Hordeum murinum), perennial ryegrass (Festuca perennis), and Kentucky bluegrass (Poa pratensis), and common non-native herbaceous species (or forbs) such as spring vetch (Vicia sativa), redstem filaree (Erodium Item 7.c

1.0 Introduction
5 cicutarium), cut-leaf geranium (Geranium dissectum), dandelion (Taraxicum officinale), bristly 0xtongue (Helminthotheca echioides), bull mallow (Malva nicaeensis), bur clover (Medicago polymorpha), and white clover (Trifolium repens).

The Urban habitat also includes a ruderal field vegetated primarily with non-native weedy species in the northeast portion of the project area between the community garden and the forest habitat along the river. This ruderal field is not mowed. Vegetation includes the non-native grasses and forbs found in the play fields such as wild oat, ripgut brome, foxtail barley, spring vetch, dandelion, and cut-leaf geranium, but also species such as curly dock, greater periwinkle, bedstraw, wild radish (Raphanus sativa), pennyroyal (Mentha spicata), and Himalaya berry (Rubus armeniacus), and other larger plants such as non-native sweet fennel (Foeniculum vulgare) and native California blackberry.

Riverine (adjacent area of the Russian River)
Structure. Intermittent or continually running water distinguishes rivers and streams. A stream originates at some elevated source, such as a spring or lake, and flows downward at a rate relative to slope or gradient and the volume of surface runoff or discharge. Velocity generally declines at progressively lower altitudes, and the volume of water increases until the enlarged stream finally becomes sluggish. Over this transition from a rapid, surging stream to a slow, sluggish river, water temperature and turbidity will tend to increase, dissolved oxygen will decrease, and the bottom will change from rocky to muddy. Riverine systems are often lacking in vegetation.

1.5.5 Soils
Soil survey information for the Review Area was obtained from the National Resources Conservation Service (NRCS) Web Soil Survey (NRCS 2022) (Appendix C). Four (4) different soil types (Pleasanton loam, 0 to 2 percent slopes, Pleasanton gravelly loam, 2 to 5 percent slopes; Flood plains / Sandy and gravelly alluvium; and Yolo sandy loam, 0 to 2 percent slopes) are mapped by NRCS within the Review Area as described in Appendix C, Table 1. The table summarizes the soil units and soil associations, together with their physical and hydrologic characteristics that were identified as being present based on a Natural Resources Conservation Service Custom Soil Resources Report prepared for the Review Area.

1.5.6 Climate.

Based on WETS Station “HEALDSBURG, CA” precipitation and temperature data for the period of record (1971 – 2022), the average annual precipitation amount received approximately 6.5 miles from the site is 41.67 inches received as rainfall and 0.00 inches received as snow. The average minimum and maximum precipitation amount ranges between 0.05 and 8.08 inches. The wettest months, in which average monthly rainfall exceeds 7.00 inches, are January, February, and December (8.01, 7.78, and 8.08 inches) with the lowest average amount occurring in July and August (0.05 and 0.09 inches).

Record data also indicates that the annual average daily temperature is 60.6 ° F. Average high and low temperatures range between 74.1 ° F and 47.0 ° F with the coldest months typically including January and December where temperatures are in the upper 30s and the hottest months being July and August where temperatures are in the lower 70s. The annual growing season with a 50% probability of having days above 32° F is 302 days (February 7 to December 6), and, with a 70% probability of having days above 32° F, is 321 days (January 29 to December 16) (Appendix D).

Item 7.c

1.0 Introduction
6 1.5.7 Hydrology
Watersheds. A review of the US Geological Survey (USGS) National Hydrography Dataset (NHD) Hydrologic Unit Code (HUC) data shows that the Review Area lies within the 8‐digit HUC (18010110) “Russian” subbasin and the 12-digit HUC (180101100605) “Brooks Creek-Russian River” subwatershed.

Direction of Surface Water Flow. Surface water that flows within the Review Area is the direct result of precipitation and associated stormwater runoff. This stormwater is collected by an incised natural drainage which directs flows to the southern edge of the Review Area. Streamflow from the Project Site stream travels south southwesterly towards and into the Russian River. Russian River surface flows run into the Pacific Ocean (Appendix F).

1.5.8 FEMA Flood Zone
FEMA Flood Insurance Rate Map for “Sonoma County” 06097C0551E (Effective Date: 12/2/2008) indicates the Project Site is within of FEMA zoning associated with an annual chance flood hazard (AE:
1% Annual Chance Flood Hazard; and Regulatory Floodway) (Appendix A, Figure 4).

1.5.9 Aquatic Resources
National Wetlands Inventory. Appendix A, Figure 5a, U.S. Fish and Wildlife Service National Wetlands Inventory Mapping, shows Palustrine, Emergent Persistent, Seasonally Flooded (PEM1C) and Riverine Lower Perennial, Unconsolidated Bottom, Permanently Flooded (R2UBH) wetlands within the Review Area.

1.6 Disclaimer
Huffman-Broadway Group, Inc., on behalf of the Applicant, has made a good‐faith effort herein to thoroughly describe and document the presence of potential factors that the Corps may consider in asserting jurisdiction pursuant to Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act. Nevertheless, the Applicant reserves the right to challenge or seek revision to any areas over which the Corps may assert such jurisdiction, should such jurisdiction be further clarified or altered through formal guidance, assertions, or disclaimers of jurisdiction over other properties, court decisions, or other relevant actions.

7 2.0 DELINEATION METHODS

2.1 Overview
HBG’s investigation focused on the identification and delineation of aquatic resource areas that potentially meet:

1. the definition of Waters of the US (33 CFR 328.3 (a)(1)-(5)) as wetlands or in the absence of wetlands have an Ordinary High Water Mark (OHWM).

2. the definition of Navigable Waters (33 CFR 329.4) by having an OHWM or Mean High Tide Line.

2.2 Preparation
In preparation for detailed field investigations, HBG identified existing landforms within the Review Area that would likely contain aquatic resources that may potentially meet the definition of WOTUS (wetlands and non-wetlands) and/or Navigable Waters by reviewing available online information sources to include: Google Earth Pro and ESRI most current and historical aerial photography and imagery; USGS National Hydrography Dataset watershed mapping; FEMA mapping; National Wetlands Inventory mapping; a NRCS Custom Soil Resources Report; and most current and historical USGS topographic mapping. Review Area-specific LIDAR topographic mapping was also reviewed.

2.3 Field Investigations
HBG conducted field investigations on February 27, 2024 to:

1. Determine the presence or absence of hydrophytic vegetation, hydric soil, and wetland hydrology indicators and document the indicators observed and their location.

2. Determine if the wetland field indicators observed may be “significantly disturbed” or “naturally problematic.”

3. Determine within any drainage and depressional area found if a high water mark is present and document the type of water mark indicators observed and location.

2.3.1 CWA Wetlands Definition and Delineation Methodology Wetlands are defined at 33 CFR § 328.3 (c)(1) as:

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.

The methodology described in the Corps’ Delineation Manual, Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (Regional Supplement), was followed to determine the presence or absence of vegetation, soil, and hydrology indicators.

2.0 Delineation Method
8 was uncertainty regarding application of the delineation methodology or interpretation of field data, the Corps’ 1987 Delineation Manual was referred to.

Vegetation, soil, and hydrology observations were made at sampling locations determined to be representative of landform areas where the soils may potentially flood, pond, and/or saturate.

Vegetation was sampled first. Soil, vegetation, and hydrology observations were recorded on Corps data forms (Wetland Determination Data Form – Arid West Region; Version 2.0) (Appendix E). Sample point locations were documented as polygonal and point features, respectfully using ESRI Apps (Field Maps) in conjunction with a Trimble DA2 Global Positioning System (GPS) receiver with sub-meter accuracy after geo-processing. The data collected was incorporated into the Project database using GIS software.

2.3.2 CWA OTHER WATERS DEFINITION AND DELINEATION METHODOLOGY Other types of CWA WOTUS aquatic resources that are not wetlands as defined at 33 CFR § 328.3 (a) have the following limits of jurisdiction 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.

The meaning of adjacent, high tide line, ordinary high water mark, and tidal waters as described above are defined by 33 CFR § 328.3 (c) follows:

Adjacent means having a continuous surface connection. 33 CFR § 328.3 (c)(2) 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. 33 CFR§ 328.3 (c)(3) Item 7.c
515 of 697

2.0 Delineation Method
9 Ordinary high water mark means that line on the shore established by the fluctuations of water and indicated by physical characteristics such as clear, natural line impressed on the bank, 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. 33 CFR§ 328.3 (c)(4)
Tidal waters means those waters that rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and sun. Tidal waters end where the rise and fall of the water surface can no longer be practically measured in a predictable rhythm due to masking by hydrologic, wind, or other effects. 33 CFR§ 328.3 (c)(5) Field observations of physical features such as those described above which are indicative of a WOTUS Ordinary High Water (OHW) were recorded, if present, on the Corps’ Rapid Ordinary High Water Mark (OHWM) Field Identification Data Sheet (ENG Form 6250, Aug 2021) data form. The methodology used to identify and define an OHWM, if present, was based on the OHWM Field Guide (Lichvar and McColley 2008) and the National Ordinary High Water Mark Field Delineation Manual for Rivers and Streams: Interim Version (Gabrielle, et al., 2022). Given the Review Area is an inland desert, no observations were made to determine the presence/absence of indicators of an HTL. If present, OHWM sample point locations were documented as point features, respectfully using ESRI Apps (Field Maps) in conjunction with a Trimble DA2 Global Positioning System (GPS) receiver with sub-meter accuracy after geo-processing. The data collected was incorporated into the Project database using GIS software.

2.3.3 RHA NAVIGABLE WATERS DEFINITION AND DELINEATION METHODOLOGY Navigable Waters as defined at 33 CFR § 329.4 have the following limits of jurisdiction as:

Non-Tidal Waters
…. 1. The "ordinary high water mark" on non-tidal rivers is the 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; 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. 33 CFR § 329.11 (Geographic and Jurisdictional Limits of Rivers and Lakes)… Corps wetland determination data forms were used to record field observations of physical features indicative of ordinary high water marks (Wetland Determination Data Form – Arid West Region; Version 2.0) (Appendix E).

Navigable Water such as those described above which indicate the presence of a non-tidal Ordinary High Water (OHW) were recorded, if present, on Corps’ Rapid Ordinary High Water Mark (OHWM) Field Identification Data Sheet (ENG Form 6250, Aug 2021) data form. OHWM sample point locations were documented as point features using ESRI Apps (Field Maps) in conjunction with a Trimble DA2 Global Positioning System (GPS) receiver with sub-meter accuracy after geo-processing. The data Item 7.c

2.0 Delineation Method
10 collected was incorporated into the Project database using GIS software.

2.4 Rainfall Analysis
The Corps’ Antecedent Precipitation Tool (APT) was used to assess precipitation conditions within the Review Area 90 days prior to field investigations. The rainfall analysis followed the latest Corps guidance. The purpose of the antecedent precipitation analysis was to aid in: (1) determining if the climatic/hydrologic conditions observed on the site are typical for the time of year in which field investigations were conducted (e.g., rainy season versus dry season); and (2) establishing whether observations made of surface and near-surface hydrology indicators or the lack thereof are the result of naturally problematic hydrology conditions (e.g., drought year, extreme precipitation/stormwater runoff event) preceding the field investigations. The APT assesses the presence of drought conditions and facilitates the comparison of recent rainfall conditions for a given location to the range of normal rainfall conditions that occurred during the preceding 30 years.

2.5 Mapping

2.5.1 CWA Wetland and Other Waters Observations
The GPS data collected during field sampling were incorporated into an HBG Project database using Geographic Information System (GIS) software and were geo-referenced in overlay fashion onto a digital topographic base map (LIDAR) and an orthorectified digital aerial photograph following national mapping standards. Data overlays of indicator observations were mapped to assist in the analysis to determine if areas meet the Corps’ WOTUS definition. The geographic extent of areas identified as being potential wetlands or other waters were mapped and classified to the class level using the US Fish and Wildlife Service’s Classification System for Wetland and Deepwater Habitats (Cowardin et al. 1979).

2.5.2 RHA Navigable Waters Observations
The GPS data collected during field sampling were incorporated into an HBG Project database using Geographic Information System (GIS) software and were geo-referenced in overlay fashion onto a digital topographic base map (LIDAR) and an orthorectified digital aerial photograph following national mapping standards. Data overlays of indicator observations were mapped to assist in the analysis to determine if areas meet the Corps’ Navigable Waters definition. The geographic extent of areas identified as being potential Navigable Waters were mapped and classified to the class level using the US Fish and Wildlife Service’s Classification System for Wetland and Deepwater Habitats (Cowardin et al. 1979).

11 3.0 TECHNICAL FINDINGS
Section 3.1 provides the technical findings regarding an analysis of whether climatic/hydrologic conditions within the Review Area are typical for the time of year in which field studies were conducted.

Section 3.2 provides the results of an analysis to determine if normal circumstances occur in the Review Area. Section 3.3 provides technical findings regarding the presence or absence of wetland hydrophytic, hydric soil, and wetland hydrology indicators observed in aquatic resource areas within the Review Area. Section 3.4 describes technical findings regarding the presence of an Ordinary High Water Mark (OHWM) observed in aquatic resources within the Review Area.

3.1. Precipitation Analysis
According to APT analysis results, the February 2024 field survey for wetland vegetation, hydric soils, and hydrology field indicators and OHWM indicators was conducted during the wet season with a mild wetness drought index within the watershed following a 90-day period of wetter than normal precipitation conditions (Appendix D).

3.2 Normal Circumstances Analysis
An analysis was conducted to determine if “Normal Circumstances” are present in the Review Area.

The following information was considered during the analysis:

The Corps’ Delineation Manual interprets "normal circumstances" as:
…. the soil and hydrologic conditions that are normally present, without regard to whether the vegetation has been removed [7 CFR 12.31(b)(2)(i)] [Manual page 71].

The expired Corps Regulatory Guidance Letter (RGL 90-07) states:
…. 4. The primary consideration in determining whether a disturbed area qualifies as a Section 404 wetland under "normal circumstances" involves an evaluation of the extent and relative permanence of the physical alteration of wetlands hydrology and hydro-phytic vegetation. In addition, consideration is given to the purpose and cause of the physical alterations to hydrology and vegetation. For example, we have always maintained that areas where individuals have destroyed hydrophytic vegetation in an attempt to eliminate the regulatory requirements of Section 404 remain part of the overall aquatic system and are subject to regulation under Section 404. In such a case, where the Corps can determine or reasonably infer that the purpose of the physical disturbance to hydrophytic vegetation was to avoid regulation, the Corps will continue to assert Section 404 jurisdictions. …..

Detailed review of Google Earth Pro aerial photography and imagery from December 1985 to April 2023 shows that land use in the Review Area consists of undeveloped lands.

Based on consideration of the above, normal circumstances are determined to be present given the long-standing nature of the land use.

3.0 Technical Findings
12 vegetation conditions are not significantly disturbed2.

Naturally Problematic Hydrophytic Vegetation Analysis and Determination: Vegetation was determined not to be naturally problematic.
3 Presence of Hydrophytic Vegetation Indicators. Forested wetland areas were dominated by patches of the following facultative wetland species: Box elder (Acer negundo). The facultative species California blackberry (Rubus ursinus) was occasionally present4.

3.3.2 Field Indicators of Hydric Soils
Significantly Disturbed Soil Analysis and Determination. A detailed review of Google Earth Pro aerial photography and imagery of the Review Area and onsite inspection (see Appendix G) indicated soil conditions are not significantly disturbed.

Naturally Problematic Soil Analysis and Determination. The NRCS Custom Soil Resources Report in Appendix C provides detailed soil mapping and descriptions for the Review Area. Onsite examination of soils found that the NRCS soil mapping provided in the report is relatively accurate and the soils examined were determined not naturally problematic.

Presence of Hydric Soil Indicators. Hydric soil indicator F3 (Depleted matrix) was observed during the field survey.

3.3.3 Field Indicators of Wetland Hydrology
Significantly Disturbed Hydrology Analysis and Determination. A detailed review of Google Earth Pro aerial photography and imagery of the Review Area and onsite inspection (see Appendix G) indicated that hydrology conditions are notsignificantly disturbed.

Naturally Problematic Hydrology Analysis and Determination. Based on a review of April 20, 2023 aerial imagery (Appendix A, Figure 3) and onsite APT analysis data (Appendix D), field indicators of wetland hydrology conditions were determined to not be naturally problematic. Based on the APT analysis, wetter than normal precipitation conditions occurred within the Review Area before site investigations.

Presence of Wetland Hydrology Indicators. Wetland hydrology indicators (B1 – Water Marks; B2 - Sediment Deposits; B3 – Drift Deposits; and B10 – Drainage Patterns) were found within the Review Area in the stream channels.

3.3.4 Wetland Aquatic Resources Identified and Delineated A dominance of hydrophytic vegetation or hydric soils was found. Aquatic resources meeting the CWA Section 404 definition of wetlands as provided in Section 4.1(4), below were found based on the collective presence of wetland vegetation, hydric soil, and wetland hydrology indicators. 2 Disturbed areas consist of sites where vegetation, soil, or hydrology indicators may be impacted (obscured or absent) due to recent human activities or natural events. 3 Naturally problematic refers to problem areas that are naturally occurring wetland types that lack indicators of hydrophytic vegetation, hydric soil, or wetland hydrology periodically due to normal seasonal or annual variability, or permanently due to the nature of the soils or plant species on the site. 4 https://cwbi-app.sec.usace.army.mil/nwpl_static/v34/home/home.html Item 7.c

3.4.1 Field Indicators of Ordinary High Water
The following describes indicators of an OHWM in stream channels within the Review Area.

Observable Physical Features. OHWMs were observed within streams in the Review Area (Appendix A, Figure). Physically, streams exhibited bed and bank characteristics. Appendix A, Figure 6 shows locations where streams having an OHWM were identified and measured. Flow indicators within these streams included at least two or more of the following: sand & gravel bars; cut banks; drift: organic; headcuts; rills; scour; vegetation-channel alignment; water level marks; and wrack: woody. Appendix E provides field data sheets. Appendix E provides OHWM widths and latitude/longitude locations where OHWM determinations were made within the Review Area. Appendix G provides representative photographs of stream channel features within the Review Area.

3.4.2 Formation
A detailed review of December 1985 to April 2023 Google Earth Pro historical aerial imagery and onsite inspection indicates the stream channels within the Review Area are naturally formed.

3.4.3 Flow Characteristics
Flow. Online USGS National Hydrography Dataset mapping indicates surface water flow patterns within stream channels are in a southwesterly direction.
5 The Review Area is within the USGS HUC 8 Russian
(18010110) subbasin. Appendix A, Figures 1 and 2 show the Review Area location within the USGS HUC 12 Brooks Creek-Russian River (180101100605) subwatersheds. The majority of surface water that flows within the Review Area to the Russian River is the direct result of precipitation. These flows are conveyed by several intermittent tributaries (Appendix A, Figure 6, see stream segments R2 – R7). The Russian River has a perennial surface flow to the Pacific Ocean (Appendix F). 6 3.4.4 Aquatic Resources Having a High Water Mark Identified and Delineated Non-tidal aquatic resource areas consisting of stream channels with OHWMs were observed within the Review Area (Appendix E).

14 4.0 POTENTIAL WATERS OF THE US (WOTUS)
This section identifies and delineates the geographic extent of aquatic resources found which meet the Clean Water Act (CWA) Section 404 definition of Waters of the US (WOTUS) (33 CFR 328.3 (a)(1)-(5)) based on the technical findings provided in Sections 3.3 and 3.4.

4.1 Definition of WOTUS
33 CFR 328.3 (a)(1)-(5) defines WOTUS as:
(1) Waters which are:
(i) Currently used, or 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; (ii) The territorial seas; or (iii) Interstate waters;
(2) Impoundments of waters otherwise defined as waters of the United States under this definition, other than impoundments of waters identified under paragraph (a)(5) of this section; (3) Tributaries of waters identified in paragraph (a)(1) or (2) of this section that are relatively permanent, standing or continuously flowing bodies of water;
(4) Wetlands adjacent to the following waters: (i) Waters identified in paragraph (a)(1) of this section; or (ii) Relatively permanent, standing or continuously flowing bodies of water identified in paragraph (a)(2) or (a)(3) of this section and with a continuous surface connection to those waters; (5) Intrastate lakes and ponds, streams, or wetlands not identified in paragraphs (a)(1) through (4) of this section that are relatively permanent, standing or continuously flowing bodies of water with a continuous surface connection to the waters identified in paragraph (a)(1) or (a)(3) of this section.

4.2 Geographical Limits of WOTUS
The geographical limit of federal jurisdiction as applies to WOTUS under Section 404 of the CWA are defined at 33 CFR Part 328.4 in the following manner:
(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, or (3) When the water of the United States consists only of wetlands jurisdiction extends to the limit of the wetlands.
33 CFR 328.3(c) provides the following relevant definitions regarding the above-defined geographical limits of federal jurisdiction:
(1) Wetlands means those areas that are inundated or saturated by surface or ground water at a frequency Item 7.c
521 of 697

4.0 Aquatic Resources Potentially Subject to CWA Federal Jurisdiction 15 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.
(2) Adjacent means having a continuous surface connection. (3) 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. (4) Ordinary high water mark means that line on the shore established by the fluctuations of water and indicated by physical characteristics such as clear, natural line impressed on the bank, 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. (5) Tidal waters means those waters that rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and sun. Tidal waters end where the rise and fall of the water surface can no longer be practically measured in a predictable rhythm due to masking by hydrologic, wind, or other effects.

4.3 Aquatic Resources within the Review Area

4.3.1 Wetlands
Based on analysis of the technical findings in Section 3.3.3, aquatic resource areas were identified and delineated within the Review Area that meet the above CWA Section 404 definition of wetlands. This analysis consisted of determining whether at a given location there was a collective presence of hydric soil, wetland hydrology, and hydrophytic vegetation field indicators as required by the 1987 Corps Delineation Manual criteria. Appendix A, Figure 6 shows the locations of wetlands that are potentially subject to Corps and USEPA Section 404 CWA jurisdiction as WOTUS.

4.3.2 Aquatic Resources with An Ordinary High Water Mark Intermittent streams having an OHWM were identified and delineated within the Review Area (Section

3.4.4). The intermittent stream channels within the Review Area direct surface water flows to the Russian River (Appendix F). The Russian River was also identified to have an OHWM. Appendix A, Figure 6 shows other waters (streams/tributaries) that are potentially subject to Corps and USEPA Section 404 CWA jurisdiction as WOTUS.

4.4 Conclusions
Aquatic resources are present which consist of wetlands as defined by 33 CFR 328.3 (a)(4) and tributaries as defined by 33 CFR 328.3 (a)(3). Appendix A, Figure 6 shows the aquatic resources identified and delineated which are potentially subject to Corps and USEPA Section 404 CWA jurisdiction.

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.

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, 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.

INTRODUCTION
The Badger Park Redevelopment Master Plan project is located in the City of Healdsburg, California. The project will expand and upgrade existing amenities such as the parking lot, play structure, and dog park as well as add new amenities such as sport courts and picnic areas. Sensitive receptors in the vicinity of the project site include single-family residences to the east and west as well as multifamily residences the north. The Russian River borders the southern boundary of the project site.

Figure 1 shows the project site plan. Figure 2 shows an aerial photo of the project site.

ENVIRONMENTAL SETTING

BACKGROUND INFORMATION ON NOISE
Fundamentals of Acoustics
Acoustics is the science of sound. Sound may be thought of as mechanical energy of a vibrating object transmitted by pressure waves through a medium to human (or animal) ears. If the pressure variations occur frequently enough (at least 20 times per second), then they can be heard and are called sound. The number of pressure variations per second is called the frequency of sound and is expressed as cycles per second or Hertz (Hz).

Noise is a subjective reaction to different types of sounds. Noise is typically defined as (airborne) sound that is loud, unpleasant, unexpected or undesired, and may therefore be classified as a more specific group of sounds.

Perceptions of sound and noise are highly subjective from person to person.

Measuring sound directly in terms of pressure would require a very large and awkward range of numbers. To avoid this, the decibel scale was devised. The decibel scale uses the hearing threshold (20 micropascals), as a point of reference, defined as 0 dB. Other sound pressures are then compared to this reference pressure, and the logarithm is taken to keep the numbers in a practical range. The decibel scale allows a million-fold increase in pressure to be expressed as 120 dB, and changes in levels (dB) correspond closely to human perception of relative loudness.

The perceived loudness of sounds is dependent upon many factors, including sound pressure level and frequency content. However, within the usual range of environmental noise levels, perception of loudness is relatively predictable, and can be approximated by A-weighted sound levels. There is a strong correlation between A-weighted sound levels (expressed as dBA) and the way the human ear perceives sound. For this reason, the A-weighted sound level has become the standard tool of environmental noise assessment.

\\192.168.1.50\Saxelby Acoustics\General\Job Folders\231203 Badger Park Redevelopment Master Plan IS-MND\Word\231203 Badger Park Redevelopment Master Plan.docx The decibel scale is logarithmic, not linear. In other words, two sound levels 10-dB apart differ in acoustic energy by a factor of 10. When the standard logarithmic decibel is A-weighted, an increase of 10-dBA is generally perceived as a doubling in loudness. For example, a 70-dBA sound is half as loud as an 80-dBA sound, and twice as loud as a 60-dBA sound.

Community noise is commonly described in terms of the ambient noise level, which is defined as the allencompassing noise level associated with a given environment. A common statistical tool is the average, or equivalent, sound level (Leq), which corresponds to a steady-state A-weighted sound level containing the same total energy as a time varying signal over a given time period (usually one hour). The Leq is the foundation of the composite noise descriptor, Ldn, and shows very good correlation with community response to noise.

The day/night average level (DNL or Ldn) is based upon the average noise level over a 24-hour day, with a +10- decibel weighing applied to noise occurring during nighttime (10:00 p.m. to 7:00 a.m.) hours. The nighttime penalty is based upon the assumption that people react to nighttime noise exposures as though they were twice as loud as daytime exposures. Because Ldn represents a 24-hour average, it tends to disguise short-term variations in the noise environment.

Table 1 lists several examples of the noise levels associated with common situations. Appendix A provides a summary of acoustical terms used in this report.

\\192.168.1.50\Saxelby Acoustics\General\Job Folders\231203 Badger Park Redevelopment Master Plan IS-MND\Word\231203 Badger Park Redevelopment Master Plan.docx Effects of Noise on People
The effects of noise on people can be placed in three categories:
• Subjective effects of annoyance, nuisance, and dissatisfaction • Interference with activities such as speech, sleep, and learning • Physiological effects such as hearing loss or sudden startling Environmental noise typically produces effects in the first two categories. Workers in industrial plants can experience noise in the last category. There is no completely satisfactory way to measure the subjective effects of noise or the corresponding reactions of annoyance and dissatisfaction. A wide variation in individual thresholds of annoyance exists and different tolerances to noise tend to develop based on an individual’s past experiences with noise.

Thus, an important way of predicting a human reaction to a new noise environment is the way it compares to the existing environment to which one has adapted: the so-called ambient noise level. In general, the more a new noise exceeds the previously existing ambient noise level, the less acceptable the new noise will be judged by those hearing it.

With regards to increases in A-weighted noise level, the following relationships occur:
• Except in carefully controlled laboratory experiments, a change of 1-dBA cannot be perceived; • Outside of the laboratory, a 3-dBA change is considered a just-perceivable difference; • A change in level of at least 5-dBA is required before any noticeable change in human response would be expected; and
• A 10-dBA change is subjectively heard as approximately a doubling in loudness and can cause an adverse response.

Stationary point sources of noise – including stationary mobile sources such as idling vehicles – attenuate (lessen) at a rate of approximately 6-dB per doubling of distance from the source, depending on environmental conditions (i.e. atmospheric conditions and either vegetative or manufactured noise barriers, etc.). Widely distributed noises, such as a large industrial facility spread over many acres or a street with moving vehicles, would typically attenuate at a lower rate.

EXISTING NOISE AND VIBRATION ENVIRONMENTS

EXISTING NOISE RECEPTORS
Some land uses are considered more sensitive to noise than others. Land uses often associated with sensitive receptors generally include residences, schools, libraries, hospitals, and passive recreational areas. Sensitive noise receptors may also include threatened or endangered noise-sensitive biological species, although many jurisdictions have not adopted noise standards for wildlife areas. Noise sensitive land uses are typically given special attention in order to achieve protection from excessive noise.

Sensitivity is a function of noise exposure (in terms of both exposure duration and insulation from noise) and the types of activities involved. In the vicinity of the project site, sensitive land uses include existing singlefamily residential uses to the east and west of the project site and multifamily residential uses to the north of the project site.

EXISTING GENERAL AMBIENT NOISE LEVELS
The existing noise environment in the project vicinity is defined by traffic on Matheson Street, activity at the existing park, and natural sounds such as birds and insects. To quantify the existing ambient noise environment in the project vicinity, Saxelby Acoustics conducted continuous (24-hr.) noise level measurements at three locations on the project site. Noise measurement locations are shown on Figure 2. A summary of the noise level measurement survey results is provided in Table 2. Appendix B contains the complete results of the noise monitoring.

The sound level meters were programmed to record the maximum, median, and average noise levels at each site during the survey. The maximum value, denoted Lmax, represents the highest noise level measured. The average value, denoted Leq, represents the energy average of all of the noise received by the sound level meter microphone during the monitoring period. The 10th percentile value, denoted L10, represents the sound level exceeded 10 percent of the time during the monitoring period.

Larson Davis Laboratories (LDL) model 820 precision integrating sound level meters were used for the ambient noise level measurement survey. The meters were calibrated before and after use with a CAL 200 acoustical calibrator to ensure the accuracy of the measurements. The equipment used meets all pertinent specifications of the American National Standards Institute for Type 1 sound level meters (ANSI S1.4).

FUTURE TRAFFIC NOISE ENVIRONMENT AT OFF-SITE RECEPTORS
Based upon the analysis conducted by the traffic engineer (W-Trans 2024) the proposed improvement to the existing park is predicted to increase daily project trips by 91 vehicles. The proposed project traffic increases are projected to generate a day/night average level of 38.5 dBA Ldn at the existing sensitive receptors along Heron Drive. The existing ambient noise level at these receptors due to traffic along this road was measured to be 55 dBA Ldn at 30 feet to the centerline of the roadway. Sensitive receptors are set back 60 feet from the roadway centerline. Therefore, Saxelby Acoustics estimates an existing traffic noise level of 50.5 dBA Ldn based upon an assumed -4.5 dBA reduction per doubling of distance from a roadway source. The combined noise level of existing plus project traffic would be 50.8 dBA Ldn, resulting in an increase of 0.3 dBA over existing traffic noise levels.

EVALUATION OF PROJECT OPERATIONAL NOISE ON EXISTING SENSITIVE RECEPTORS Outdoor recreational noise associated with the proposed athletic amenities and parking lot traffic circulation are considered to be the primary noise sources for this project. The following is a list of assumptions used for the noise modeling. Project operational noise is assumed to occur during daytime (7:00 am. to 8:00 p.m.) hours only. The data used is based upon Saxelby Acoustics data from similar operations.

Tennis/Pickleball Courts: Pickleball gameplay is expected to produce noise levels of approximately 60 dBA L10 at 25 feet from the edge of the end of a single court and 58 dBA L10 at 25 feet from the edge of the side of a single court.

Basketball Courts: Recreational activity at center of court at 59 dBA L10 at 50 feet. Saxelby Acoustics data.

Play Area: Recreational activity in center of playground area at 59 dBA L10 at 50 feet. Saxelby Acoustics data.

Dog Park: Dogs and people entering dog run area at entrance was found to produce noise levels of 54 dBA L10 at 50 feet. Dogs interacting and playing as well as dog owners interacting with each other and their pets produced 54 dBA L10 at rear boundary of dog run area. Saxelby Acoustics data.

On-Site Circulation: The project is projected to generate up to 91 daily trips with 13 trips (7 in, 6 out) in the evening peak hour (W-Trans 2024). One heavy truck trip was included to account for trash collection. Parking lot movements are predicted to generate a sound exposure level (SEL) of 71 dBA SEL at 50 feet for cars and 85 dBA SEL at 50 feet for trucks. Saxelby Acoustics data.

Saxelby Acoustics used the SoundPLAN noise prediction model. Inputs to the model included sound power levels for the proposed amenities, existing and proposed buildings, terrain type, and locations of sensitive receptors. These predictions are made in accordance with International Organization for Standardization (ISO) standard 9613‐2:1996 (Acoustics – Attenuation of sound during propagation outdoors). ISO 9613 is the most commonly used method for calculating exterior noise propagation. Figure 3 shows noise level contours generated by the project during a peak hour of use.

REGULATORY CONTEXT

FEDERAL
There are no federal regulations related to noise that apply to the Proposed Project.

STATE
California Environmental Quality Act
The California Environmental Quality Act (CEQA) Guidelines, Appendix G, indicate that a significant noise impact may occur if a project exposes persons to noise or vibration levels in excess of local general plans or noise ordinance standards, or cause a substantial permanent or temporary increase in ambient noise levels.

CEQA standards are discussed more below under the Thresholds of Significance section.

State Building Code, Title 24, Part 2 of the State of California Code of Regulations The State Building Code, Title 24, Part 2 of the State of California Code of Regulations, establishes uniform minimum noise insulation performance standards to protect persons within new buildings which house people, including hotels, motels, dormitories, apartment houses, and dwellings other than single-family dwellings. Title 24 mandates that interior noise levels attributable to exterior sources shall not exceed 45 dB Ldn or CNEL in any habitable room. Title 24 also mandates that for structures containing noise-sensitive uses to be located where the Ldn or CNEL exceeds 60 dB, an acoustical analysis must be prepared to identify mechanisms for limiting exterior noise to the prescribed allowable interior levels. If the interior allowable noise levels are met by requiring that windows be kept closed, the design for the structure must also specify a ventilation or air conditioning system to provide a habitable interior environment.

LOCAL
City of Healdsburg General Plan
Policies
Policy S-G-1: New development shall not be approved unless it is generally consistent with the Land Use Compatibility for Community Noise Environments guidelines contained in General Plan Figure 10 and it is demonstrated that the new development will not violate the City’s ordinance regulating excessive noise
Policy S-G-2: The City will require the inclusion of design techniques in new construction that minimize noise impacts, including building location and orientation, building design features, and placement of noise-tolerant components (i.e., parking, utility areas, and maintenance facilities) between noise sources and the sensitive receptor areas where necessary to meet the Land Use Compatibility for Community Noise Environments guidelines contained in General Plan Table 7.

Notes: dBA = A-weighted decibels; Ldn = day-night average noise level 1 Specified land use is satisfactory based on the assumption that any buildings involved are of normal conventional construction, without any special noise insulation requirements. 2 New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements is made and after needed noise insulation features are included in the design. Conventional construction, but with closed windows and fresh-air supply systems or air conditioning, will normally suffice. 3 New construction or development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made and needed noise insulation features included in the design.

Outdoor areas must be shielded. 4 New construction or development should generally not be undertaken. 5 Outdoor private use areas 6 Outdoor active use areas, excluding balconies Policy S-25: Where construction occurs that would result in a potentially-significant impact on noisesensitive uses, require use of noise-reducing measures that may include the following:
a. Equip internal combustion engine-driven equipment with intake and exhaust mufflers that are in good condition and are appropriate for the equipment.
b. Locate stationary noise-generating equipment as far as possible from sensitive receptors in the vicinity. c. Utilize "quiet" air compressors and other stationary noise sources where technology exists. d. Erect temporary noise control blanket barriers in a manner to shield noise sensitive uses. e. Control noise levels from workers’ amplified music so that sounds are not audible sensitive receptors in the vicinity.

CRITERIA FOR ACCEPTABLE VIBRATION
Vibration is like noise in that it involves a source, a transmission path, and a receiver. While vibration is related to noise, it differs in that noise is generally considered to be pressure waves transmitted through air, whereas vibration usually consists of the excitation of a structure or surface. As with noise, vibration consists of an amplitude and frequency. A person’s perception to the vibration will depend on their individual sensitivity to vibration, as well as the amplitude and frequency of the source and the response of the system which is vibrating.

Vibration can be measured in terms of acceleration, velocity, or displacement. A common practice is to monitor vibration measures in terms of peak particle velocities in inches per second. Standards pertaining to perception as well as damage to structures have been developed for vibration levels defined in terms of peak particle velocities.

Human and structural response to different vibration levels is influenced by a number of factors, including ground type, distance between source and receptor, duration, and the number of perceived vibration events.

Table 7, which was developed by Caltrans, shows the vibration levels which would normally be required to result in damage to structures. The vibration levels are presented in terms of peak particle velocity in inches per second.

Table 7 indicates that the threshold for architectural damage to structures is 0.20 in/sec p.p.v. A threshold of

0.20 in/sec p.p.v. is considered to be a reasonable threshold for short-term construction projects.

IMPACTS AND MITIGATION MEASURES

THRESHOLDS OF SIGNIFICANCE
Appendix G of the CEQA Guidelines states that a project would normally be considered to result in significant noise impacts if noise levels conflict with adopted environmental standards or plans or if noise generated by the project would substantially increase existing noise levels at sensitive receivers on a permanent or temporary basis. Significance criteria for noise impacts are drawn from CEQA Guidelines Appendix G (Items XI [a-c]).

Would the project:
a. Generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?
b. Generate excessive groundborne vibration or groundborne noise levels? c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? The proposed project is not located within two miles of a public or private airport, therefore item “c” is not discussed any further in this study.

In practice, more specific professional standards have been developed.

These standards state that a noise impact may be considered significant if it would generate noise that would conflict with local project criteria or ordinances, or substantially increase noise levels at noise sensitive land uses. The potential increase in traffic noise from the project is a factor in determining significance. Research into the human perception of changes in sound level indicates the following:
• A 3-dB change is barely perceptible,
• A 5-dB change is clearly perceptible, and
• A 10-dB change is perceived as being twice or half as loud.

A limitation of using a single noise level increase value to evaluate noise impacts is that it fails to account for pre-project noise conditions. Table 8 is based upon recommendations made by the Federal Interagency Committee on Noise (FICON) to provide guidance in the assessment of changes in ambient noise levels resulting from aircraft operations. The recommendations are based upon studies that relate aircraft noise levels to the percentage of persons highly annoyed by the noise. Although the FICON recommendations were specifically developed to assess aircraft noise impacts, it has been accepted that they are applicable to all sources of noise described in terms of cumulative noise exposure metrics such as the Ldn.

TABLE 8: SIGNIFICANCE OF CHANGES IN NOISE EXPOSURE
Ambient Noise Level Without Project, Ldn Increase Required for Significant Impact <60 dB +5.0 dB or more
60-65 dB +3.0 dB or more
>65 dB +1.5 dB or more
Source: Federal Interagency Committee on Noise (FICON).

Based on the Table 8 data, an increase in the traffic noise level of 5 dB or more would be significant where the pre-project noise levels are less than 60 dB Ldn, or 3 dB or more where existing noise levels are between 60 to 65 dB Ldn. Extending this concept to higher noise levels, an increase in the traffic noise level of 1.5 dB or more may be significant where the pre-project traffic noise level exceeds 65 dB Ldn. The rationale for the Table 13 criteria is that, as ambient noise levels increase, a smaller increase in noise resulting from a project is sufficient to cause annoyance.

Temporary Construction Noise Impacts
With temporary noise impacts (construction), identification of “substantial increases” depends upon the duration of the impact, the temporal daily nature of the impact, and the absolute change in decibel levels. Per the City of Healdsburg Municipal Code, construction activities operating outside the hours of 7:30 am and 6:00 pm Monday through Saturday and any time on Sunday are prohibited.

The City has not adopted any formal standard for evaluating temporary construction noise which occurs within allowable hours. For short-term noise associated with Project construction, Saxelby Acoustics recommends use of the Caltrans increase criteria of 12 dBA (Caltrans Traffic Noise Protocol, 2020), applied to existing Item 7.c

This level of increase is approximately equivalent to a doubling of sound energy and has been the standard of significance for Caltrans projects at the state level for many years.

Application of this standard to construction activities is considered reasonable considering the temporary nature of construction activities.

PROJECT-SPECIFIC IMPACTS AND MITIGATION MEASURES
Impact 1: Would the project generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Traffic Noise Increases at Off-Site Receptors
The existing ambient noise level in the project vicinity was measured to be 55 dBA Ldn. Based upon the Table 8 criteria, the significance threshold for ambient noise environments less than 60 dBA Ldn is +5.0 dBA Ldn. Based upon the projected addition of 91 daily project trips, an increase in traffic noise level of 0.3 dB is predicted.

This is lower than the minimum threshold for significance. Therefore, impacts resulting from increased traffic noise would be considered less-than-significant, and no mitigation is required.

Operational Noise at Existing Sensitive Receptors
Compliance with City Noise Level Standards
The City of Healdsburg noise level standards require that new projects in the vicinity of existing sensitive receptors generate noise levels no greater than 60 dBA L10 during daytime (7:00 a.m. to 10:00 p.m.) hours at residential-zoned properties.

As shown on Figure 3, the project is predicted to expose nearby residences to noise levels up to 61 dBA L10 at receptors to the north. This would exceed the City’s noise level standard. This is a potentially significant impact and requires mitigation.

To mitigate this impact, Saxelby Acoustics recommends the construction of a 6-foot-tall sound wall along the northern boundary of the project site. Figure 4 shows the location of the wall and the resulting noise level contours. With the wall, project noise levels would be reduced from 61 dBA L10 to 55 dBA L10 at the property boundary, which is less than the City’s 60 dBA L10 standard. Therefore, mitigation measure 1(a) would reduce this to a less-than-significant impact.

Analysis of Long-Term Project-Related Increase Significance As shown in Table 2, the existing ambient noise level at sensitive receptors set back from Heron Drive was measured to be 47 dBA L10 during daytime hours. The proposed project is predicted to generate noise levels of up to 46 dBA at the nearest sensitive receptors. The ambient (47 dBA L10) plus project (46 dBA L10) noise level would be 49.5 dBA L10, resulting in an increase of 2.5 dBA L10 over the ambient noise levels. At the sensitive receptors along Heron Drive, ambient noise levels were measured to be 57 dBA L10 and project noise levels are predicted to be 48 dBA L10, resulting in a combined noise level of 57.5 dBA L10 and a 0.5 dBA increase. According to Table 8, where noise levels are less than 60 dB, an increase of +5.0 dB or greater would be considered significant. Based on the greatest predicted increase of 2.5 dB, this would be a less-than-significant impact.

During the construction phases of the project, noise from construction activities would add to the noise environment in the immediate project vicinity. As indicated in Table 3, activities involved in construction would generate maximum noise levels ranging from 76 to 90 dBA Lmax at a distance of 50 feet. Construction activities would also be temporary in nature and are anticipated to occur during normal daytime working hours.

Caltrans defines a significant increase due to noise as an increase of 12 dBA over existing ambient noise levels; Saxelby Acoustics used this criterion to evaluate increases due to construction noise associated with the project. As shown in Table 5, construction equipment is predicted to generate noise levels of up to 90 dBA Lmax at 50 feet. Construction noise is evaluated as occurring at the center of the site to represent average noise levels generated over the duration of construction across the project site. The nearest residential uses are located approximately 450 feet as measured from the center of the project site. At this distance, maximum construction noise levels would be up to 71 dBA. Daytime maximum noise levels in the vicinity of the sensitive receptors were measured to range from 49-71 dBA. Therefore, project construction would not cause an increase of greater than 12 dBA over existing ambient noise levels.

Noise would also be generated during the construction phase by increased truck traffic on area roadways. A project-generated noise source would be truck traffic associated with transport of heavy materials and equipment to and from the construction site. This noise increase would be of short duration and would occur during daytime hours.

Although construction activities are temporary in nature and would occur during normal daytime working hours, construction-related noise could result in sleep interference at existing noise-sensitive land uses in the vicinity of the construction if construction activities were to occur outside the normal daytime hours.

Therefore, impacts resulting from noise levels temporarily exceeding the threshold of significance due to construction would be considered potentially significant. Mitigation measure 1(b) would reduce construction noise impacts to less-than-significant.

Mitigation Measure(s)
Implementation of the following mitigation measures would reduce the above impact to a less-than-significant level.
1(a) The proposed project must include the construction of a 6-foot-tall barrier at the northern boundary of the project site as shown in Figure 4. The barrier height shall be relative to the residential building pads or the pickleball courts/dog park, whichever is greater. Noise barrier walls shall be constructed of concrete panels, concrete masonry units, earthen berms, or any combination of these materials that achieve the required total height. Wood is not recommended due to eventual warping and degradation of acoustical performance. These requirements shall be included in the improvement plans prior to their approval by the City.
1(b) The City shall establish the following as conditions of approval for any permit that results in the use of construction equipment:
• Construction shall be limited to 7:30 a.m. to 6:00 p.m. Monday through Saturday. • All construction equipment powered by internal combustion engines shall be properly muffled and maintained.

In addition, the project contractor shall place such stationary construction equipment so that emitted noise is directed away from sensitive receptors nearest the project site.
• Unnecessary idling of internal combustion engines is prohibited. • The construction contractor shall, to the maximum extent practical, locate on-site equipment staging areas to maximize the distance between construction-related noise sources and noise-sensitive receptors nearest the project site during all project construction.

Timing/Implementation: Implemented prior to approval of grading and/or building permits Enforcement/Monitoring: City of Healdsburg
Implementation of mitigation measures 1(a) would help to reduce construction-generated noise levels. With mitigation, this impact would be considered less-than-significant.

Transportation Noise on Project Site (Non-CEQA Issue)
Exterior Transportation Noise
Compliance with City’s standards on new noise-sensitive receptors is not a CEQA consideration. However, this information is provided here so that a determination can be made regarding the ability of the proposed project to meet the requirements of the City of Healdsburg for exterior noise levels at new uses proposed under the project.

As indicated in Table 2, noise levels measured at various locations along the project site ranged from 46 dBA Ldn to 55 dBA Ldn. This would fall under the “Normally Acceptable” range of less than 70 dBA Ldn established by the City of Healdsburg General Plan (see Table 7). Therefore, the proposed use is compatible with the existing environment and no noise control measures are required.

Impact 2: Would the project generate excessive groundborne vibration or groundborne noise levels? Construction vibration impacts include human annoyance and building structural damage. Human annoyance occurs when construction vibration rises significantly above the threshold of perception. Building damage can take the form of cosmetic or structural.

The Table 4 data indicate that construction vibration levels anticipated for the project are less than the 0.2 in/sec threshold at distances of 26 feet. Sensitive receptors which could be impacted by construction related vibrations, especially vibratory compactors/rollers, are located further than 26 feet from typical construction activities. At distances greater than 26 feet construction vibrations are not predicted to exceed acceptable levels. Additionally, construction activities would be temporary in nature and would likely occur during normal daytime working hours.

This is a less-than-significant impact and no mitigation is required.

Appendix A: Acoustical Terminology
Acoustics The science of sound.

Ambient Noise The distinctive acoustical characteristics of a given space consisting of all noise sources audible at that location. In many cases, the term ambient is used to describe an existing or pre‐project condition such as the setting in an environmental noise study.

ASTC Apparent Sound Transmission Class. Similar to STC but includes sound from flanking paths and correct for room reverberation. A larger number means more attenuation. The scale, like the decibel scale for sound, is logarithmic.

Attenuation The reduction of an acoustic signal.

A‐Weighting A frequency‐response adjustment of a sound level meter that conditions the output signal to approximate human response.

Decibel or dB Fundamental unit of sound, A Bell is defined as the logarithm of the ratio of the sound pressure squared over the reference pressure squared. A Decibel is one‐tenth of a Bell.

CNEL Community Noise Equivalent Level. Defined as the 24‐hour average noise level with noise occurring during evening hours (7 ‐ 10 p.m.) weighted by +5 dBA and nighttime hours weighted by +10 dBA.

DNL See definition of Ldn.

IIC Impact Insulation Class. An integer‐number rating of how well a building floor attenuates impact sounds, such as footsteps. A larger number means more attenuation. The scale, like the decibel scale for sound, is logarithmic.

Frequency The measure of the rapidity of alterations of a periodic signal, expressed in cycles per second or hertz (Hz).

Ldn Day/Night Average Sound Level. Similar to CNEL but with no evening weighting.

Leq Equivalent or energy‐averaged sound level.

Lmax The highest root‐mean‐square (RMS) sound level measured over a given period of time.

L(n) The sound level exceeded a described percentile over a measurement period. For instance, an hourly L50 is the sound level exceeded 50% of the time during the one‐hour period.

Loudness A subjective term for the sensation of the magnitude of sound.

NIC Noise Isolation Class. A rating of the noise reduction between two spaces. Similar to STC but includes sound from flanking paths and no correction for room reverberation.

NNIC Normalized Noise Isolation Class. Similar to NIC but includes a correction for room reverberation.

Noise Unwanted sound.

NRC Noise Reduction Coefficient. NRC is a single‐number rating of the sound‐absorption of a material equal to the arithmetic mean of the sound‐absorption coefficients in the 250, 500, 1000, and 2,000 Hz octave frequency bands rounded to the nearest multiple of 0.05. It is a representation of the amount of sound energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption.

RT60 The time it takes reverberant sound to decay by 60 dB once the source has been removed.

Sabin The unit of sound absorption. One square foot of material absorbing 100% of incident sound has an absorption of 1 Sabin.

SEL Sound Exposure Level. SEL is a rating, in decibels, of a discrete event, such as an aircraft flyover or train pass by, that compresses the total sound energy into a one‐second event.

SPC Speech Privacy Class. SPC is a method of rating speech privacy in buildings. It is designed to measure the degree of speech privacy provided by a closed room, indicating the degree to which conversations occurring within are kept private from listeners outside the room.

STC Sound Transmission Class. STC is an integer rating of how well a building partition attenuates airborne sound. It is widely used to rate interior partitions, ceilings/floors, doors, windows and exterior wall configurations. The STC rating is typically used to rate the sound transmission of a specific building element when tested in laboratory conditions where flanking paths around the assembly don’t exist. A larger number means more attenuation. The scale, like the decibel scale for sound, is logarithmic.

Threshold The lowest sound that can be perceived by the human auditory system, generally considered of Hearing to be 0 dB for persons with perfect hearing.

Threshold Approximately 120 dB above the threshold of hearing. of Pain
Impulsive Sound of short duration, usually less than one second, with an abrupt onset and rapid decay.

Simple Tone Any sound which can be judged as audible as a single pitch or set of single pitches.

TRANSPORTATION INITIAL STUDY CHECKLIST
Item 7.c

1 Draft Transportation Initial Study Checklist for the Badger Park Master Plan Project July 9, 2024
Transportation
The CEQA criteria evaluated are as follows. Would the project:
a. Conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities?
b. Conflict or be inconsistent with CEQA Guidelines § 15064.3, subdivision (b)? c. Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? d. Result in inadequate emergency access?
Project Profile
The Master Plan includes a number of improvements to Badger Park that would enhance its interface with the Russian River and increase its use. The existing playground would be expanded and upgraded, with new play structures and amenities. The dog park would be relocated, remaining approximately the same size but with new amenities. The community garden would approximately double in size. New sports courts would be constructed; none would be intended for league play and they would not be lit. Three new picnic areas with tables are also proposed. Two overlook structures would be constructed at existing promontories on the Russian River and pedestrian trails would be expanded and enhanced. A new restroom building would be added in place of the existing portable toilet. Though Badger Park at one time hosted soccer practices and games, this practice was discontinued in 2021 and is not proposed to be reinitiated. The parking supply would be increased by 21 spaces from the current supply of 46 spaces to 67 spaces.

Transportation Setting
Study Area and Periods
The study area varies depending on the topic. For pedestrian trips it consists of all streets within a half-mile of the project site that would lie along primary routes of pedestrian travel, or those leading to nearby generators. For bicycle trips it consists of all streets within one mile of the project site that would lie along primary routes of bicycle travel. For the safety and operational analyses, it consists of the project frontage.

Consideration was given to the project’s potential trip generation during the a.m. and p.m. peak periods.

The morning peak hour occurs between 7:00 and 9:00 a.m. and reflects conditions during the home to work or school commute, while the p.m. peak hour occurs between 4:00 and 6:00 p.m. and typically reflects the highest level of congestion during the homeward bound commute.

Policies and Standards
The Healdsburg 2030 General Plan includes numerous goals, policies and implementation measures that are related to transportation facilities, as follows.

Goal T-B. Minimal traffic accidents and hazards.

Goal T-D. Bicycle and pedestrian routes and facilities that provide safe and convenient access and an alternative to the use of motor vehicles.

Item 7.c
648 of 697
2 Draft Transportation Initial Study Checklist for the Badger Park Master Plan Project July 9, 2024
Policy T-B-2. Special attention will be given to providing adequate corner sight distances at intersections and private access drives and roadways.

Policy T-D-1. The use of alternative transportation modes shall be encouraged by establishing a safe and convenient bicycle and pedestrian network interconnecting residential areas with recreation, shopping and employment areas.

Policy T-D-3. The City shall develop a citywide system of safe and convenient designated bikeways that serves both experienced and casual bicyclists, and which maximizes bicycle use for commuting, recreation, and local transportation.

Policy PS-28. Complete gaps in the pedestrian and bicycle systems.

Policy PS-29. Maintain the pedestrian and bicycle systems in good condition.

Implementation Measure T-12. Implement the Bicycle & Pedestrian Master Plan as opportunities arise and require development projects to dedicate land and/or construct/install bicycle and pedestrian facilities in coordination with the Plan.

Implementation Measure T-13. Designate and establish specific east-west and north-south bicycle routes through the downtown area where feasible.

Implementation Measure T-14. Continue to place bicycle racks as requested by property owners and demand grows at public destinations.

Implementation Measure T-15. Continue to improve the pedestrian network interconnecting residential areas with recreation, shopping and employment as opportunities arise, including as part of development projects.

Trip Generation
The anticipated trip generation for the proposed project was estimated using standard rates published by the Institute of Transportation Engineers (ITE) in Trip Generation Manual, 11th Edition, 2021, for Tennis Courts (LU #490), as this description most closely matches the changes the project proposes to the existing park facilities. The trip rate does not include an a.m. peak hour rate, but as traffic during the morning peak hour is typically lower, the p.m. peak hour was considered as the most critical. There is also not an in-out percentage provided for the p.m. peak hour so data for Public Parks (LU #411), 55 percent of trips inbound and 45 percent of outbound, was used as the project would likely have similar travel patterns. Based on the application of these rates, the proposed project is expected to generate an average of 91 additional trip per day, with 13 trips added during the p.m. peak hour. This information is summarized in Table 1.

3 Draft Transportation Initial Study Checklist for the Badger Park Master Plan Project July 9, 2024
Circulation System
This section addresses the first transportation bullet point on the CEQA checklist, which relates to the potential for a project to conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities.

Pedestrian Facilities
Existing and Planned Pedestrian Facilities
Pedestrian facilities include sidewalks, crosswalks, pedestrian signal phases, curb ramps, curb extensions, and various streetscape amenities such as lighting, benches, etc. In general, a network of sidewalks, crosswalks, and curb ramps provide access for pedestrians in the vicinity of the proposed project site. • Heron Drive – Sidewalk coverage is provided on Heron Drive with sidewalks on the south side for its entire length and on the north side from 400 feet south of the intersection of South Fitch Mountain Road/Heron Drive to the eastern terminus of Heron Drive. Sidewalks are provided along developed property frontages. Curb ramps and crosswalks at side street approaches but lack truncated domes.

Lighting is intermittently provided by overhead, pedestrian-scale streetlights. • South Fitch Mountain Road – Continuous sidewalks are provided on the south side of South Fitch Mountain Road between its western terminus and Orangewood Drive. Sidewalks are not provided on the north side of the street. Vehicle-scale lighting is provided intermittently along the street. • Continuous sidewalks are present along one side of the entire length Falcon Way, Heron Court, Raven Court, Almond Way, Hummingbird Couty, Quail Court, Carnary Court, Sparrow Court, and Crane Court as well as the streets to the west of Heron Drive within the study area. • No sidewalks are present along the streets east of Almond Way. These streets are local streets that provide access to residences on both sides. Sidewalks are generally not provided along these local streets.

No new pedestrian facilities are planned in the study area according to the Healdsburg Bicycle & Pedestrian Master Plan, Sonoma County Transportation Authority, 2013, nor are any off-site facilities planned as part of the project. The project would, however, provide additional trails through the park and connecting to the Russian River.

Pedestrian Safety
The collision history for the study area was reviewed to determine any trends or patterns that may indicate a safety issue for pedestrians. Collision records available from the California Highway Patrol as published in their Statewide Integrated Traffic Records System (SWITRS) reports were reviewed for the most current fiveyear period available, which was October 1, 2018, through September 30, 2023, at the time of the analysis.

During the five-year study period, there were no reported collisions involving pedestrians along Heron Drive and South Fitch Mountain Road.

Project Impacts on Pedestrian Facilities
Given the proximity of residential land uses to the north, east, and west of the site, it is reasonable to assume that some project patrons will want to walk, bicycle, and/or use transit to reach the project site. The project as proposed would improve pedestrian access from 2nd Street. Since the project as proposed would not Item 7.c
650 of 697
4 Draft Transportation Initial Study Checklist for the Badger Park Master Plan Project July 9, 2024
change the frontage with Heron Drive and the nearby pedestrian network is already fully connected the project would have a less-than-significant impact on pedestrian facilities.

Finding – The project as proposed would be compliant with City’s pedestrian policies.

Bicycle Facilities
Existing and Planned Bicycle Facilities
The Highway Design Manual, Caltrans, 2020, classifies bikeways into four categories:
• Class I Multi-Use Path – a completely separated right-of-way for the exclusive use of bicycles and pedestrians with cross flows of motorized traffic minimized. • Class II Bike Lane – a striped and signed lane for one-way bike travel on a street or highway. • Class III Bike Route – signing only for shared use with motor vehicles within the same travel lane on a street or highway.
• Class IV Bikeway – also known as a separated bikeway, a Class IV Bikeway is for the exclusive use of bicycles and includes a separation between the bikeway and the motor vehicle traffic lane. The separation may include, but is not limited to, grade separation, flexible posts, inflexible physical barriers, or on-street parking.

In the project area, a Class II bike lane exists on the north side of South Fitch Mountain Road between Greens Street and 650 feet east of Latimer Road. No bicycle facilities are proposed near the project site in the City of Healdsburg’s Healdsburg Bicycle & Pedestrian Master Plan. Bicyclists ride in the roadway and/or on sidewalks along all other streets within the project study area.

Bicyclist Safety
Collision records for the study area were reviewed to determine if there had been any bicyclist-involved crashes. During the five-year study period between October 1, 2015, through September 30, 2020, there was no reported collision involving a bicyclist along Heron Drive or South Fitch Mountain Road Project Impacts on Bicycle Facilities
The project as proposed would not change any of the streets nor does it front on a street that is planned to have new bicycle facilities. The project would not impact any existing or planned bicycle facilities so the project as proposed would have a less-than-significant impact on bicycle facilities.

Finding – Bicycle facilities serving the project site are compliant with the City’s bicycle policies.

Transit Facilities
Existing Transit Facilities
Sonoma County Transit (SCT) provides fixed-route bus service in Healdsburg. Route 67 provides loop service to destinations throughout the City of Healdsburg and stops adjacent to the project site on Heron Drive and Riverside Club House. Route 67 operates Monday through Saturday from 8:40 a.m. to 4:10 p.m. with headways that range from one hour to one-and-one-half hours.

Two or three bicycles can be carried on most SCT buses. Bike rack space is on a first-come, first-served basis. Riders are responsible for both loading and unloading their bicycles.

Item 7.c
651 of 697
5 Draft Transportation Initial Study Checklist for the Badger Park Master Plan Project July 9, 2024
Dial-a-ride, also known as paratransit, or door-to-door service, is available for those who are unable to independently use the transit system due to a physical or mental disability. SCT Paratransit is designed to serve the needs of individuals with disabilities.

Impact on Transit Facilities
Given the SCT bus route serving the project site and the existing access to the transit stop that is adjacent to the project site, the existing transit route is adequate to accommodate project-generated transit trips.

The project as proposed is not expected to increase the use of existing transit facilities as local parks typically serve local residents and is thus expected to have a less-than-significant impact on transit facilities.

Finding – The project as proposed would be compliant with the City’s transit policies.

Significance Finding – The proposed project would not conflict with any plans or policies for transportation facilities and would improve pedestrian access from 2nd Street. It would have a less-than-significant impact on these facilities.

Vehicle Miles Traveled (VMT)
The potential for the project to conflict or be inconsistent with CEQA Guidelines § 15064.3, subdivision (b) was evaluated based the project’s anticipated Vehicle Miles Traveled (VMT) and the City’s VMT Policy.

The City of Healdsburg has adopted guidelines for the analysis of vehicle miles traveled (VMT). The City’s policy identifies several criteria that may be used to identify certain types of projects that are unlikely to have a VMT impact and can be “screened” from further VMT analysis. One of these screening criteria pertains to small projects, which the City identifies as generating fewer than 110 vehicle trips per day. As shown in Table 1, the proposed project is anticipated to generate approximately one daily vehicle trips, which falls below the City’s threshold. As a result, it is reasonable to conclude that the project can be presumed to have a less-than-significant impact on VMT.

Significance Finding – The project would be expected to have a less-than-significant impact in terms of VMT.

Safety Issues
The potential for the project to impact safety was evaluated in terms of the adequacy of sight distance and the need for turn lanes at the project driveway to accommodate project-generated trips. This section addresses the third transportation bullet on the CEQA checklist which is whether or not the project would substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment).

Site Access
The project site is currently served by a driveway on Heron Drive and the project would not result in any changes to the driveway or trip generation that affect site access, safety, or sight distance.

Consideration was given to the need for a left-turn lane on Heron Drive at the project entrance. However, as all or nearly all trips to the site are from Matheson Street/South Fitch Mountain Road and result in a right turn into the driveway, the volume would not be sufficient to warrant a turn lane, especially on a street with as low a volume as Heron Drive.

Item 7.c
652 of 697
6 Draft Transportation Initial Study Checklist for the Badger Park Master Plan Project July 9, 2024
Significance Finding – The project would not result in any design elements or operational changes that would cause a safety concern. The project would therefore have a less-than-significant impact on safety.

Emergency Access
The final transportation bullet on the CEQA checklist requires an evaluation as to whether the project would result in inadequate emergency access or not.

Emergency response vehicles would be able to access the site via the project driveway on Heron Drive. The existing, 27-foot driveway meets the 20-foot driveway access requirement for emergency vehicles in Ordinance No. 1194, City of Healdsburg, 2019. The addition of project-generated traffic would have no perceptible effect on traffic operation and would therefore result in no increase in response times.

Significance Finding – The proposed project would have a less-than-significant impact on emergency response.

CITY COUNCIL AGENDA STAFF REPORT
MEETING DATE: November 3, 2025
SUBJECT: Foley Family Community Pavilion Phase 1 Operational Plan PREPARED BY: Matt Milde, Recreation Supervisor; and
Anna Grant, Active Adult & Senior Services Supervisor
STRATEGIC INITIATIVE(S):
- Maintain and improve infrastructure and facilities
- Provide effective governance
- Provide resident-driven community services
RECOMMENDED ACTION(S):

Review the proposed Foley Family Community Pavilion Phase 1 Operation Plan for City and City-Partnered events and Facility Use Permits, the proposed criteria and recommendation for events that would remain in the Plaza, and the Parks and Recreation Commission's recommendations and provide direction to staff to incorporate in the Operation Plan for adoption at a future meeting.

COMMUNITY ENGAGEMENT/OUTREACH:

The Foley Family Community Pavilion (the “Pavilion”) project reflects over a decade of community engagement and outreach efforts, including public open houses and public information meetings with the community at-large, design workshops with focus groups such as special event organizers, Healdsburg Chamber of Commerce, and representatives of the Healdsburg Farmers’ Market, and numerous Parks and Recreation Commission, Planning Commission, and City Council meetings and work sessions.

BACKGROUND:

In Spring 2025, Community Services staff began developing an operational plan framework to guide the policies and procedures for managing the Pavilion. This work has been guided by existing City policies, Community Services operation procedures, Municipal Code, community event organizer input, and review of operational models from similar types of facilities. In addition, the Parks and Receation Commission established an ad-hoc committee to work with staff on developing the operational plan.

Item 9.a
669 of 697
Between August to October, staff met with the Parks and Recreation Commission’s Ad Hoc Committee, local nonprofit organizations, community event organizers, and City department teams to review the draft framework and gather feedback. Using that input, staff prepared Phase 1 of the Pavilion’s Operational Plan for the Parks and Recreation Commission’s review and feedback and consideration by City Council. Also, during the creation of the plan, staff solicited and received inquiries from potential users about types of events and potential dates.

Construction of the Pavilion is anticipated to be completed in November 2025. Most of the events that could use the Pavilion under the Phase 1 Operational Plan will be considered by City Council as part of the 2026 Master Calendar of Events in December. Examples of these special events include Vamos al Tianguis beginning in January and the Healdsburg Farmers’ Market in April.

Other activities may be permitted under the Facility Use Permit program.

DISCUSSION/ANALYSIS:

The proposed Foley Family Community Pavilion Phase 1 Operational Plan is comprised of three sections:
• An overview of the facility
• A plan for day-to-day informal use by the public
• Policies and procedures for the management of City and City-Partnered special events and Facility Use Permits
In summary, the proposed plan outlines how the facility will be scheduled and prioritized for use, and the plan defines policies related to daily public use and rental use. At its core, the plan is designed to balance broad public access with the need to facilitate community events within existing budget and staffing capacity.

Section 1 – Facility Overview
The Phase 1 Operational Plan provides a description of the Foley Family Community Pavilion, including its purpose, physical layout, and operational intent. Designed as a flexible open-air venue in the heart of Healdsburg, the Pavilion is the new home of the Healdsburg Certified Farmers’ Markets and serves as a community gathering space intended to reduce the impact of events on the downtown Plaza. The section explains that this operational plan establishes the framework for dayto-day management and City-partnered use, ensuring the facility is managed within existing staffing capacity. At this stage, private and non-City partnered rentals are intentionally excluded until staff resources allow for expansion.

Highlights include:
• Overview of functional areas with capacity and square footage information. • Facility features include: Pavilion, A/V closet, four unisex restrooms, storge room, catering kitchen, designated cooking area, and parking lot.
• On-site utilities include free Wi-Fi, ample power, and access to water. • The role of North Street closures during Pavilion events.

Section 2 – Facility Use Policies and Procedures
Item 9.a
670 of 697
The second section details the policies, operating rules, and staffing structure necessary for maintaining a safe, accessible, and welcoming environment for general public day-to-day use. It outlines hours of operation, public use expectations, and specific restrictions designed to protect the facility and its users. The section also reinforces City ordinances governing alcohol, smoking, pets, motorized devices, and adherence to the Municipal Code and California Vehicle Code.

Lastly, this section provides a clear staffing framework to ensure consistent oversight and maintenance.

Highlights include:
• The Pavilion is open daily from 6:00 a.m. to 10:00 p.m. for passive public use • Groups of 20 people or more require a permit
• Parking lot use guidelines
• Day-to-Day Staffing:
 Full-time Community Services staff are responsible for permits, logistics, and coordination.
 Parks and Facilities Aides handle custodial and event support.  Other City departments—Police, Fire, IT, Public Works, and Central Services—are identified as key partners in ensuring safe and efficient operations.

Section 3 – Permitted Use Policies and Procedures
The final section outlines the procedures for permitted events, including application steps, insurance requirements, and operational guidelines for City and City-partnered uses. This section also outlines use under the existing Facility Use Permit program. Comprehensive subsections address public safety, waste management, alcohol service, food operations, road closures, and environmental compliance.

Highlights include:
• Defines rental tiers prioritizing use of the Healdsburg Farmers’ Market followed by Citysponsored and co-sponsored events. • Organizations may submit a request for a special event partnership that is reviewed by City Council.
• Rental use of the Pavilion may occur between 6:00 a.m. – Midnight including set-up and cleanup; Event hours must be held between 7:00 a.m. – 10:00 p.m. • No deposits or fees required for the Healdsburg Certified Farmers’ Market of City-partnered events.
• Incorporates access to the Pavilion under the City’s Facility Use Permit program. A Facility Use Permit would allow individuals or organizations access to the Pavilion for a wide range of activities or events that does not otherwise require a special event permit. This permit is applicable to organized activities between 20-100 persons, and is available for a Citysponsorship if approved by the Community Services Director. Examples of past activities that occurred under a Facility Use Permit include the Healdsburg Garden Club’s annual plant sales in West Plaza Park, Healdsburg Museum’s History Talks in the Plaza, and Redwood Empire food distribution at the City Hall Parking Lot.

Item 9.a
671 of 697
In summary, the Phase 1 Operational Plan is intended to ensure that the Foley Family Community Pavilion becomes a vibrant community asset; one that supports the Healdsburg Farmers’ Market, enhances opportunities for community gatherings, provides space for special events with a varying degree of space needs.

Considerations:

Healdsburg Certified Farmers’ Market – The Healdsburg Farmers’ Market has an existing use agreement with the City for the use of West Plaza Parking Lot and the Plaza that will need to be updated and presented to City Council at a future meeting.

Private and Non-City Partnered Events – The FY25-26 adopted budget does not contain dedicated appropriations for operating the Pavilion. Therefore, the proposed operational plan reallocates existing budget and staffing resources from already-planned events at other locations to the Pavilion.

In addition, by prioritizing our daily management and our foundational users, the City can refine operational logistics, staffing, preventative maintenance practices, and community access protocols before expanding to include private and non-City partnered uses in the future when appropriate budget and staffing allocations are available. This phased approach would help the City develop the overall operational plan that ensures that the Pavilion operates efficiently, sustainably, and equitably for all.

Finally, once the City opens the facility to non-City or non-City partnered events, we must open the facility to all events, including private events: restricting special events in the Pavilion to only certain designated groups could be an unlawful restriction of speech. While the First Amendment allows the City to regulate time, place, and manner of expression in public spaces in service of an important governmental interest, such as public safety and quiet enjoyment, it does not allow us to choose one group over another. For example, we can implement limitations as to the number of events, but we can’t restrict the types of events or event sponsors.

Continued Use of the Plaza – After careful consideration, staff recommends that the City specify specific parameters for continued use of Plaza Park for special events in an effort to ease the impact special events have of the Plaza and to ensure the investment the community has made to the Foley Family Community Pavilion is maximized. Staff proposes that special event use of the Plaza continue under the following parameters that would be designated as “Signature Events”:
• City-managed special events
• Facility Use Permits (activities under 100-people approved by the Community Services Director)
• Co-organized Events that meet Section 8 of the Policy for Special Events and City Partnerships that have been approved by City Council
• Long-standing community events that serve a broad demographic Based on the above requirements, the following events are proposed to be Signature Events that would continue to be hosted in the Plaza:
• Tuesdays in the Plaza
Item 9.a
672 of 697
• Merry Healdsburg
• Dia de Muertos
• Fourth of July Celebration (Parade & Duck Dash)
• Sundays in the Plaza
• Unanticipated events that may arise as a result of an unforeseen or unanticipated significant event or occurrence, such as the Welcome Home celebration following the Kincade Fire Policy and Code Revisions – Upon the final determination of operation plan by City Council, several updates to the Healdsburg Municipal Code and Policy for Special Event and City Partnerships would need to occur. In the future, the City Council will also need to amend the Adopted Fee Schedule to incorporate proposed fees.

Parks and Recreation Commission’s Recommendation
The Parks and Recreation Commission reviewed the proposed Foley Family Community Pavilion Phase 1 Operational Plan at its October 21 meeting. Following discussion and public comment, the Commission voted to recommend that the City Council approve the Operational Plan with the following modifications:

1. The Commission recommends that the Healdsburg Jazz Festival’s Juneteenth Celebration be designated as a Signature Event for 2026 and remain in the Plaza for 2026.

Background: Healdsburg Jazz Executive Director Gayle Okumura Sullivan addressed the Commission, noting that performers for the 2026 Juneteenth Celebration, scheduled for Saturday, June 13, have already been confirmed. Because the Pavilion will not be available for use until after the Saturday Farmers’ Market concludes, the Festival’s pre-scheduled program would be adversely affected if required to relocate. Beginning in 2027, the Jazz Festival intends to move the Juneteenth Celebration to a Sunday, allowing the event to transition to the Pavilion.

2. The Commission recommends that staff evaluate the feasibility of introducing non-City partnered and private events at the Pavilion prior to the start of the FY 26–28 budget cycle.

Background: The Pavilion’s operation is not funded in the FY 25–26 budget; therefore, the proposed Phase 1 Operational Plan allocates existing resources toward the Healdsburg Farmers’ Market and City-sponsored events through the remainder of FY 25–26 by relocating some existing events (i.e., from the Plaza and City Hall parking lot) to the Pavilion. Under the current plan, staff would prepare an expanded operational model for non-City partnered and private rentals as part of the FY 26–28 budget process, with potential implementation beginning July 1, 2026. However, recognizing growing community interest and potential demand for use of the Pavilion, the Commission recommended that City Council direct staff to explore funding opportunities within the FY 25–26 budget to enable additional event uses sooner.

ENVIRONMENTAL STEWARDSHIP:

Item 9.a
673 of 697
• The Operational Plan includes comprehensive plan for addressing garbage, waste, and composting for daily operations and special events.
• The Organizer would be required to utilize as many reusable and compostable materials as possible to move towards zero-waste events, and would be required to meet or exceed all current waste and conservation requirements that are in place by the State, County and/or City at the time of the events.
• California law (AB 2176) requires special events and public venue facilities with more than 2,000 participants per day to develop and implement a waste management plan. As a condition of approval, the Organizer must submit a detailed waste management plan and will be expected to follow their plan during their permitted activities.

ALTERNATIVES:
• Approved proposed plan incorporating some or all of the recommendations of the Parks and Recreation Commission.
• Recommend denial of the proposed plan or recommend changes to the proposed plan. The Pavilion would be open the public, but no events would occur in the space, which may have a negative impact on the Healdsburg Farmers’ Markets and City-sponsored events.

FISCAL IMPACT:

The Pavilion is not funded in the FY 25–26 budget; therefore, the proposed Phase 1 Operational Plan reallocates existing budget and resources, primarily from Special Events and Park Maintenance programs, through the remainder of FY 25–26.

ENVIRONMENTAL ANALYSIS:

Review of a proposed operational plan for the Foley Family community Pavilion is not subject to the provisions of the California Environmental Quality Act ("CEQA") because it is not a project, since it will not have a direct or reasonably foreseeable indirect impact on the environment. In addition, special events are considered normal operations of existing facilities for public gatherings (CEQA Guidelines Section 15323).

Section 1: Overview
The Foley Family Community Pavilion serves as a dynamic, open-air venue in the heart of Healdsburg, designed as the home for the Healdsburg Farmers’ Markets, and a welcoming space for community events and gatherings. Designed to enhance Healdsburg’s communal life and lessen the impact events have on the Healdsburg Plaza, the Pavilion supports a diverse range of uses maintaining a strong emphasis on versatility. This operational plan establishes the framework for day-to-day management, outlines rental guidelines, and defines procedures that ensure the Pavilion remains a well-maintained and vibrant community asset.

The focus of the operational plan is to ensure that the City and Healdsburg-based community groups under City partnership can utilize the facility and gain a clear understanding of this new community asset. At the same time, it allows the City to prepare for managing the facility within existing staff capacity. Accordingly, events hosted by local non-profit organizations or community groups, in addition to private rentals, are not included in the initial operational plan but will be evaluated and considered at a future date.

Pavilion
The Foley Family Community Pavilion is a versatile open-air facility designed to accommodate a wide range of community gatherings, public events, and special activities. The Pavilion features access to four unisex restrooms, scattering kitchen, storage room, a/v closet, and utilities including water, power, and free public Wi-Fi. Permitted community events will have access to the Catering Kitchen and the outdoor Designated Cooking Area.

The Catering Kitchen provides a convenient space for food staging and service, but renters are responsible for supplying their own catering staff, equipment, and serving supplies. The kitchen is equipped with a 3-door commercial refrigerator, deep sink, and serving table to support event needs. However, it does not include a warming oven, stove, microwave, freezer, or garbage disposal. Renters should plan accordingly and make arrangements for any additional equipment required for their event.

The Pavilion storage room is reserved for City-owned items that support the operation and maintenance of the facility, including excess or backup equipment, custodial supplies, and event-related materials. Dedicated lockers within the storage area are provided for on-site staff to store personal belongings and personal protective equipment (PPE). A designated portion of the storage room is also allocated year-round for the Healdsburg Certified Farmers Market to store a moderate amount of essential equipment used for each market. The storage area is not open to the general public, and renter access is restricted solely to custodial supplies needed during their event.

Pavilion Parking Lot
The Pavilion Parking Lot, which contains 42 spaces, will remain open for general public use unless it is specifically reserved in conjunction with a Pavilion rental. Event organizers may reserve the lot for event-related purposes such as food trucks, vendor booths, tents, ticketed parking, or other approved programming. Access to power is available throughout the lot.

All parking lot rentals must be arranged in advance through the rental application process, with the requested hours of use clearly identified in the rental agreement. Renters are responsible for managing all logistics associated with their use of the lot, which may include traffic control, signage, staffing, and fee collection if applicable. At the conclusion of the rental, the lot must be returned to its original condition.

North Street Closure
Event organizers may request the closure of North Street as part of their rental application.

Approval of any street closure is contingent upon review by the City and rental use of the Item 9.a
677 of 697
Pavilion Parking Lot. When North Street is closed, the Pavilion Parking Lot may not be utilized for ticketed parking.

Under rare circumstances, the City may require the renter to hire a professional traffic management vendor to conduct the closure and provide the necessary equipment and signage.

Any contracted traffic management vendor must comply with the Department of Transportation’s Manual on Uniform Traffic Control Devices (MUTCD).

Section 2: Facility Use Policies and Procedures
To ensure a welcoming and enjoyable experience for all, visitors of the Foley Family Community Pavilion are asked to follow the Pavilion’s policies and procedures. These guidelines promote safe, respectful, and responsible use of the space to help protect both the facility and those who enjoy it. By following these facility rules, visitors will help keep the Pavilion a vibrant, well-maintained venue for community events, casual gatherings, and programs.

The facility is regulated under the Healdsburg Municipal Code, specifically Chapter 12.28 (Parks) and Chapter 12.24 (Special Events); Section 8 of City of Healdsburg Resolution 150- 2023 (Policy for Special Events and City Partnerships) relating to City-Partnered Special Events; the California Vehicle Code; and the site-specific policies described in this document.
