small number of arroyo willows (Salix lasiolepis, FACW) occur on the southern boundary along Civic Center Way that have an understory of upland weeds including carnation spurge (Euphorbia terracinna, UPL), ripgut brome (Bromus diandrus, UPL), and summer mustard (Hirschfeldia incana, UPL).
The area immediately west of the potential wetland areas (described below) is dominated by areas of pampas grass (Cortederia selloana, FACU), carnation spurge (Euphorbia terracinna, UPL), ripgut brome (Bromus diandrus, UPL), castor bean (Ricinus communis, FACU), and summer mustard (Hirschfeldia incana, UPL) and is clearly upland.
Based on initial site reconnaissance and focused surveys and vegetation mapping, it was determined that because of the high level of disturbance, the portions of the site immediately north of the wetland areas that occupies the southern edge of the site does not support suitable habitat for special-status plants with the exception of the California walnut. Nevertheless, focused surveys were conducted in the throughout the Study Area in accordance with CDFW’s March 20, 2018 “Protocols for Surveying and Evaluating Impacts to Special-Status Native Plant Populations and Sensitive Natural Communities”, which require the survey provide for inspection of all areas of potential habitat by direct observation by walking meandering transects through areas of suitable habitat.
No special-status plants were detected on the site including within the wetland area and the areas north of the wetland area.

DATE: October 19, 2019 [Updated June 31, 2023] [Revised October 21, 2024] SUBJECT: Results of Determination and Delineation of Potential Wetlands and Environmentally Sensitive Habitat Area on the 7.19-Acre Smith Parcel, City of Malibu, California
Wetland Specialists from Glenn Lukos Associates (GLA) conducted a site review of the Smith Parcel in the City of Malibu [Exhibits 1 and 2] to evaluate the site for areas of potential wetlands as defined by the City of Malibu LCP and California Coastal Act. The initial site visit by GLA was conducted on June 25, 2018, with subsequent visits conducted on April 4, May 23, 2019, and June 4, 2019. More recently, site visits were conducted by GLA to update the 2018 and 2019 data on June 14, 2023. The evaluation also considered whether the site contains wetlands subject to the jurisdiction of the U.S. Army Corps of Engineers (Corps) pursuant to Section 404 of the Clean Water Act, Regional Water Quality Control Board (Regional Board) pursuant to Section 401 of the Clean Water Act or Waste Discharge Requirements of Porter Cologne, or a lake or stream subject to the jurisdiction of the California Department of Fish and Wildlife pursuant to Section 1602 of the Fish and Game Code. At the request of the City of Malibu, the limits of Environmentally Sensitive Habitat Area (ESHA) have been mapped coincident with the extent of the wetlands.
Site Description
The 7.13-acre Smith Parcel is in the City of Malibu, adjacent to Civic Center Way, just west of Stuart Ranch Road [Exhibit 2]. The northern approximately half of the parcel consists of nonnative grassland dominated by ripgut brome (Bromus diandrus, UPL), and includes a few small clumps of non-native trees and native and non-native shrubs. A portion of the southern half of the parcel supports a mosaic of native vegetation, including alkali meadow dominated by saltgrass (Distichlis spicata, FAC) and alkali weed (Cressa truxillensis, FACW), and emergent marsh dominated by California bulrush (Schoenoplectus californica, OBL) and hardstem bulrush (Schoenoplectus acutus, OBL), with patches of Mexican rush (Juncus mexicanus, FACW).
Between the bulrush-dominated marsh and saltgrass areas is an area dominated by a roughly equal mix of non-native curly dock (Rumex crispus, FAC) and alkali bulrush (Schoenoplectus 441

maritimus). A small number of arroyo willows (Salix lasiolepis, FACW) occur on the southern boundary along Civic Center Way that have an understory of upland weeds including carnation spurge (Euphorbia terracinna, UPL), ripgut brome (Bromus diandrus, UPL), and summer mustard (Hirschfeldia incana, UPL) and generally occur outside of the wetland boundary.
The area immediately west and northwest of the potential wetland areas (described below) is dominated by areas of pampas grass (Cortederia selloana, FACU), carnation spurge (Euphorbia terracinna, UPL), ripgut brome (Bromus diandrus, UPL), castor bean (Ricinus communis, FACU), and summer mustard (Hirschfeldia incana, UPL) and is clearly upland. At the southwest corner of the wetland is a small patch of arroyo willow with an understory of pampas grass, carnation spurge, and other upland species that was evaluated for wetland conditions.
Similarly, areas to the north of the wetland consist of upland areas dominated by non-native grasses and forbs including ripgut brome (Bromus diandrus, UPL), wild oats (Avena fatua, UPL), garland chrysanthemum (Glebionis coronaria, UPL), western ragweed (Ambrosia psilostachya, FACU), and wild radish (Raphanaus sativus, UPL) with saltgrass which occurs beyond the wetland boundary where non-native upland grasses are predominant.
Wetlands Defined under City of Malibu LCP
In accordance with definitions in the Coastal Act, the City of Malibu LCP defines wetlands as follows:
WETLAND - is defined by Section 30121 of the Coastal Act as lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes, freshwater marshes, open or closed brackish water marshes, swamps, mudflats, and fens. The definition of wetland is further detailed by Section 13577 (b)(1) of the California Code of Regulations as land where the water table is at, near, or above the land surface long enough to promote the formation of hydric soils or to support the growth of hydrophytes, and shall also include those types of wetlands where vegetation is lacking and soil is poorly developed or absent as a result of frequent and drastic fluctuations of surface water levels, wave action, water flow, turbidity or high concentrations of salts or other substances in the substrate. Such wetlands can be recognized by the presence of surface water or saturated substrate at some time during each year and their location within, or adjacent to vegetated wetlands or deep-water habitats.
According to the Coastal Commission, the presence of any one of three wetland indicators (hydrology, hydrophytes or hydric soils) qualifies an area as a wetland under this definition.
Furthermore, the Coastal Commission establishes the upland limit of a wetland as:
442
MEMORANDUM
October 19, 2019 [Updated July 31, 2023] [Revised October 21, 2024]
a. the boundary between land with predominantly hydrophytic cover and land with predominantly mesophytic or xerophytic cover
b. the boundary between soil that is predominantly hydric and soil that is predominantly nonhydric; or
c. in the case of wetlands without vegetation or soils, the boundary between land that is flooded or saturated at some time during years of normal precipitation, and land that is not (14 CCR Section 13577).
The Commission’s determination of the presence of a “One Parameter Wetland” typically follows the methods contained in the U.S. Army Corps of Engineers’ 1987 Wetland Delineation Manual1
(Wetland Manual) and more recently, the 2008 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (AWS v.2.0).2 It should be noted, however, that the Army Corps of Engineers and the Wetland Manual requires the presence of all three factors – wetlands hydrology, hydric soils, and a predominance of hydrophytic vegetation – to determine the presence and delineate the boundaries of a federal wetland. As noted, while the Commission relies on the federal manuals to establish the presence of any of the three parameters, according to Commission staff, typically, the presence of a single parameter (e.g., a predominance of wetland vegetation) is sufficient to demonstrate the presence of a wetland and for the Commission to make a presumptive finding for the presence of wetlands.
Methodology
The site was evaluated during the noted site visits in 2018, 2019, and 2023 for the presence of 1) areas with a predominance of wetland vegetation, 2) the presence of hydric soils, and 3) the presence of field indicators for wetland hydrology. In accordance with the Malibu LCP and Coastal Act wetland definition, the presence of any one of these criteria is potentially sufficient for a determination that wetlands occur, and these same criteria were used to establish the geographic extent of potential wetlands on the site. As discussed in the results section below, as for most delineations in the Coastal Zone, the vegetation is often the criteria that defines the wetland boundary. As such, hydric soils and wetland hydrology are addressed first, followed by a discussion of the methods to define the boundary of potential wetlands based on a predominance of wetland vegetation.

Hydric Soils
Soil pits were excavated at numerous locations on the site to determine whether hydric soils were present. Examination of the soils was performed in accordance with the methodology set forth in the AWS v.2.0. It is important to note that soils pits were not excavated at each paired location because hydric soil indicators were entirely lacking along the wetland boundary in 2018, 2019, and again in 2023, and in fact, from most of the site. Weak indicators for the presence of hydric soils were only detected in the central, wettest portion of the wetland. Data sheets from 2018, 2019, and 2023 include the soils data collected during the site visits. Data Sheets from the 2018/2019 delineation efforts and from the 2023 data collection are included as Appendices A and B.
Wetland Hydrology
Indicators for the presence of wetland hydrology were evaluated at each of the locations where data was collected in accordance with the methodology set forth in the AWS v.2.0 during the June 25, 2018 and April 2, 2019 site visits. In addition, historic aerial photographs were examined for signs of standing or ponded water during the wet season (October through April).
Specifically, aerial photographs from December 2003, November 2004, December 2005, March 2006, April 2011, December 2013, and February 2016 were examined and the only aerial photograph that showed any ponding was the April 2011 photo which showed two small ponded areas near the western portion of the wetland, measuring 30 by 80 feet and 16 by 40 feet covering an estimated 0.65 acre. The 2022/2023 rainfall season produced nearly double the average rainfall, which resulted in ponding that extended beyond the edge of the wetland as delineated in 2018 and 2019 and ultimately as mapped in 2023 based on the limits of areas with a predominance of plants with an indicator status of FAC or wetter as discussed below.
For an area to meet the minimum threshold for wetland hydrology according to the AWS v.2.0, it must exhibit saturation in the upper 12 inches of the soil surface for a duration sufficient to cause anaerobic conditions (typically considered 14 days) during at least every other year (i.e., 50/100 years). Given this requirement, the potential wetland area does not appear to exhibit wetland hydrology along the outer edges. This would be consistent with observation that saltgrass, a phreatophyte, dominate the outer edges of the wetland. In these areas saltgrass is supported by subsurface water at depths of six feet or deeper (up to 11 feet) as discussed below.
Wetlands Vegetation
Vegetation data was collected at numerous points in 2018 and 2019, with most of the 36 data points collected during 2018 and 2019 established primarily along the northern boundary of the potential wetland to determine the northern extent of wetland, as well as at locations near the eastern and western boundaries of the wetland. Data collection in 2023 included 32 data points 444
MEMORANDUM
October 19, 2019 [Updated July 31, 2023] [Revised October 21, 2024]
concentrated along the northern and western wetland boundaries. Exhibit 3 depicts the location of wetland based on data points in 2018 and 2019. Exhibit 4 depicts the wetland based on the data collected in 2023. The vegetation data along the northern edge in 2018 and 2023 was in most instances collected at “paired” data point locations, with one of the paired data points in potential wetlands and a paired data point in the adjacent uplands along the eastern, northern and western boundary of the wetland [see Exhibits 3 and 4]. At each data point location, the percent cover for each species was recorded along with the wetland indicator status. The presence of hydrophytic wetland indicator plant species was determined based on The National Wetland Plant List.3 Typically, the paired data point locations were between five and six feet apart, and the wetland boundary was then flagged in a manner that bisected the data collection points. As discussed in more detail below, the results are potentially skewed in favor of expanded wetlands because one of the dominant wetland indicator plants, saltgrass (Distichlis spicata, FAC) is a phreatophyte, meaning it has the capacity to reach shallow groundwater (up to 11 feet below the surface), and is thus not a reliable indicator for the presence of wetlands in the absence of hydric soils and wetland hydrology. This is because for an area to be considered a wetland, hydrology must be present in the upper 12 inches of the soil profile (during 50/100 years) for sufficient duration to create anaerobic conditions. The presence of phreatophytes such as saltgrass, which are tapped into ground water at depths of many feet below the ground surface can lead to a “false positive” when considering the status of plants with an indicator status of FAC or wetter (a more detailed discussion regarding the indicator status of the plants on this parcel is included in the “Discussion” section below). After discussing the results of the 2018/2019 field investigations, as well as in 2023, a discussion of previous wetland delineations for the site is provided.

As already noted, portions of the southern half of the site support areas that exhibit a predominance of plants with an indicator status of FAC or wetter and thus are potentially wetland as defined under the Malibu LCP and the Coastal Act. Limited indicators for hydric soils were restricted to the wettest and lowest areas within the central portion of the wetland, which in some areas were not strong enough to make a positive determination for the presence of hydric soils. Primary indicators for the presence of wetland hydrology were not evident in the field during the June 25, 2018 site visit and a review of historic aerial photographs did not indicate that the central portion of the wetland ponds water during years of average rainfall. For an area to exhibit wetland hydrology, it must exhibit wetland hydrology indicators in 50/100 years and occasional ponding in above-average years would not satisfy this criterion. Surface ponding was observed within the central portion of the wetland during the April 2, 2019 site visit but did not extend to the limits of the saltgrass along the northern edge of the wetland as discussed below. It is important to note that the 2018/2019 rainfall season was above average 3 Lichvar, R.W., D.L. Banks, W.N. Kirchner, and N.C. Melvin. 2016. The National Wetland Plant List: 2016 wetland ratings.

rainfall in Malibu, compared with the annual average of 14.92 inches.4 Thus, the extent of
ponding during 2019 does not constitute average conditions (i.e., 50/100 years). As noted above, the rainfall was 169-percent of normal rainfall during the 2022/2023 rainfall season with the 2022/2023 rainfall totaling 25.08.5
Exhibit 3 depicts the wetland boundary based on the predominance of wetland indicator plants observed during the 2018 and 2019 site visits and Exhibit 4 depicts the extent of wetlands based on the predominance of wetland indicator plants during the 2023 site visit. Exhibit 5 shows the wetland boundaries from both 2019 and 2023 and it is evident that along the northern boundary, there was only minimal change, with the boundary shifting slightly south at the eastern end of the northern edge of wetland and a few areas that extend slightly further north in the central portion of the northern edge when compared with the 2019 surveys. In 2023, the wetland boundary expanded at the northwest corner of the wetland and expanded to the west as well.
The slight shift to the south along the northern wetland boundary in 2023, which as noted was a very high rainfall period that produced extensive ponding that extended to the northern wetland boundary and beyond, is best explained by the proliferation of non-native grasses and other forbs due to the excessive rainfall such that many FACU and UPL plants were dominant along the wetland boundary. The proliferation of the upland plants resulted in areas with a predominance of FACU and UPL species in this area such that these areas failed the basic dominance test for wetland vegetation. Thus, we have determined that the most accurate delineation would be achieved by consolidating the 2018/2019 and 2023 mapping. Exhibit 5 represents the consolidation of the 2018/2019 and 2023 maps, creating a wetland boundary using the outermost boundary from both years providing the most expansive/conservative wetland boundary based on the three years of data.
Previous Wetland Mapping by Others
Previous wetland delineations have been prepared for the site as discussed below. It is important to note that none of the previous delineation efforts are recent and none, except for the delineation by Edith Read in 2018, followed the Arid West Supplement, which is the current “Standard” recognized by Coastal Commission Staff. Appendix C addresses the previous jurisdictional delineations in detail, including a comparison with the GLA 2019 and 2023 delineation efforts.
Exhibit 6 depicts the extent of wetlands based on previous mapping, which includes the extent of wetlands as provided in a Coastal Commission Staff Report 5-91-086 dated March 4, 1991, which required 0.25 acre of willow plantings on the periphery of an “existing wetland mitigation 4 https://weather-and-climate.com/average-monthly-precipitation-Rainfall-inches,malibu-california-us,UnitedStates-of-America 5 http://www.laalmanac.com/weather/we139b.php 446

area”. It therefore appears that the potential wetland pre-dates 1991. This same Exhibit 6 also depicts the extent of wetlands provided by the U.S. Fish and Wildlife Service National Wetland Inventory (NWI) Maps. Both the Coastal Commission Staff Report map and the NWI map show the northern wetland boundary to the south of the area delineated by GLA in both 2019 and 2023 and overlain with the two maps on Exhibit 6. However, both maps show the wetland extending further to the west, which is not accurate given that this area is dominated by upland vegetation, including pampas grass (Cortederia selloana, FACU), carnation spurge (Euphorbia terracinna, UPL), ripgut brome (Bromus diandrus, UPL), castor bean (Ricinus communis, FACU), and summer mustard (Hirschfeldia incana, UPL), and is clearly upland.
Appendix A consists of data sheets that include the field data collected during the June 25, 2018 and June 4, 2019 site visits for vegetation, soils and hydrology. Appendix B includes the 2023 datasheets. Dominant plants during both years within the potential wetland areas include California bulrush (Schoenoplectus californica, OBL) and hardstem bulrush (Schoenoplectus acutus, OBL) in the lower, wetter areas. Between the bulrush-dominated marsh and saltgrass areas is an area dominated by an approximately equal mix of non-native curly dock (Rumex crispus, FAC) and native alkali bulrush (Schoenoplectus maritimus, OBL). Saltgrass (Distichlis spicata, FAC) and alkali weed (Cressa truxillensis, FACW) are dominant along the northern boundary.
There is a somewhat abrupt topographic transition between the northern boundary and adjacent uplands where the dominant species include ripgut (Bromus diandrus, UPL), carnation spurge (Euphorbia terracinna, UPL), western ragweed (Ambrosia psilostachya, FACU), giant horseweed (Erigeron canadensis, FACU), and yellow sweet clover (Melilotus indicus, FACU).
Exhibit 4 includes site photographs of the wetland area taken during the April 2, 2019 site visit showing the lower areas exhibiting ponding and the margins of the wetland along the northern boundary.
U.S. Army Corps of Engineers Jurisdiction
Pursuant to Section 404 of the Clean Water Act, the Corps regulates the discharge of dredged and/or fill material into waters of the United States. The term “waters of the United States” was most recently defined in the Federal Register on September 8, 2023, in the Corps’ regulations at 33 CFR Part 328.3(a)6 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

MEMORANDUM
October 19, 2019 [Updated July 31, 2023] [Revised October 21, 2024]
(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 paragraphs (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 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.
In the absence of wetlands, the limits of Corps jurisdiction in non-tidal waters, such as intermittent streams, extend to the Ordinary High Water Mark (OHWM) which is defined at 33 CFR 328.3(c)(4) as:
...that line on the shore established by the fluctuation 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.
The term “wetlands” (a subset of “waters of the United States”) is defined at 33 CFR 328.3(b) as “those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support...a prevalence of vegetation typically adapted for life in saturated soil conditions.” In 1987, the Corps published a manual to guide its field personnel in determining jurisdictional wetland boundaries. The methodology set forth in the 1987 Wetland Delineation Manual and the Arid West Supplement generally require that, to be considered a wetland, the vegetation, soils, and hydrology of an area exhibit at least minimal hydric characteristics. While the manual and Supplement provide detail in methodology and allow for varying special conditions, a wetland should normally meet each of the following three criteria:
• more than 50 percent of the dominant plant species at the site must be typical of wetlands (i.e., rated as facultative or wetter in the National List of Plant Species that Occur in Wetlands7
);
7 Lichvar, R. W. 2013. The National Wetland Plant List: 2013 wetland ratings. Phytoneuron 2013-49: 1-241. 448
MEMORANDUM
October 19, 2019 [Updated July 31, 2023] [Revised October 21, 2024]
• soils must exhibit physical and/or chemical characteristics indicative of permanent or periodic saturation (e.g., a gleyed color, or mottles with a matrix of low chroma indicating a relatively consistent fluctuation between aerobic and anaerobic conditions); and • Whereas the 1987 Manual requires that hydrologic characteristics indicate that the ground is saturated to within 12 inches of the surface for at least five percent of the growing season during a normal rainfall year, the Arid West Supplement does not include a quantitative criterion with the exception for areas with “problematic hydrophytic vegetation”, which require a minimum of 14 days of ponding to be considered a wetland.
Discussion
Based on the predominance of vegetation with an indicator status of FAC or wetter, the site currently contains approximately 1.84 acres of potential wetland in accordance with current interpretations by Coastal Staff of the Coastal Act wetland definitions, which as noted, require the presence of only one of the three wetland criteria (wetland vegetation, hydric soils, and wetland hydrology). There are a variety of factors which should be considered when making such determinations; however, it must also be stressed that the boundary of potential wetlands on Exhibit 6 would be the Commission’s default determination in the absence of more compelling data. It also should be noted that the wetland depicted in the 1991 Coastal Commission Staff Report referenced above, shows the wetland extending to the west into areas currently dominated by upland plants, including dense thickets of pampas grass (Cortederia selloana, FACU) that also lack wetland hydrology and hydric soils.
• Because the potential wetland areas do not exhibit each of the three wetland criteria, the area would not be subject to Corps jurisdiction pursuant to Section 404 of the Clean Water Act. In addition, the area lacks a continuous surface water connection with wetlands defined in 328.3(a)(1) through (3) above so the area would not be subject to Section 404 jurisdiction.
• The area does not meet the CDFW definition of a lake or stream and would not be subject to CDFW jurisdiction pursuant to Section 1602 of the California Fish and Game Code. • As noted for Section 404, because the potential wetland areas do not exhibit each of the three wetland criteria, the area would not be subject to Regional Board jurisdiction pursuant to Section 401 of the Clean Water Act or under the Waste Discharge Requirements of Porter Cologne.
Appendix C is an updated Technical Memorandum that was prepared in response to public comments that supported earlier jurisdictional delineations and rejected GLA’s 2018/2019 delineation. GLA believes that the consistency between the 2018/2019 and 2023 delineations 449

conducted by GLA provides compelling evidence for the accuracy of the GLA delineation which in total is based on 68 data points evaluated over three separate years.

TECHNICAL MEMORANDUM
1940 E Deere Avenue, Suite 250 ● Santa Ana, California 92705 ● 949.837.0404 PROJECT NUMBER: 1373-4CIVI
TO: Ed Mountford
FROM: Tony Bomkamp
DATE: December 12, 2022 [Updated July 31, 2023]
SUBJECT: Response to Patt Healy Email dated November 7, 2022 and Comparison between 2018 Read Jurisdictional Delineation and GLA Jurisdictional Delineations of 2019 and 2023
I previously reviewed the Patt Healy email dated November 7, 2022 and referenced and attached Jurisdictional Delineation Report (Psomas JD) dated February 1, 2002 prepared by Edith Read of Psomas. It is important to note that this updated response follows an updated jurisdictional delineation conducted by Glenn Lukos Associates (GLA) in 2023, which provided a review of the wetland during a rainfall year that was approximately 170-percent above normal, allowing for examination of the wetland area during extreme hydrology conditions and thus ensuring that the wetland has been review by GLA over a six year period with a full range of hydrological conditions. It is also noteworthy that during the three years when GLA collected wetland data, a total of 68 data points, mostly along the wetland boundary were examined as depicted on Exhibits 3 and 4 of GLA’s jurisdictional delineation memo dated June 30, 2023.
It is important to note that the field work for the Psomas JD was conducted over three years prior to the date of the report, specifically on December 10, 1998. Below are comments from Patt Healy followed by my responses as GLA Technical Director and Senior Wetland Specialist.
Further below, I discuss the 2018 JD update also prepared by Edith Read (though she was no longer associated with Psomas when she prepared the 2018 update).
Healy Comment:
According to the Coastal Commission, the presence of any one of three wetland indicators (hydrology, hydrophytes or hydric soils) qualifies an area as a wetland under this definition.
However the 2019 Glen [sic] Lukos Technical Memorandum prepared for Schmidt and Associates Inc didn’t strictly apply the Coastal Act definition since it excluded the saltgrass vegetation, a hydrophyte, existing on the property. Hence the Glen [sic] Lukos wetland Technical Memorandum and the Lukos Restoration Plan can’t be relied on or 596
