RE: Hydrologic Assessment, 2500 Glenneyre Street, Laguna Beach, Orange County, California The purpose of this technical memorandum is to provide an assessment of the drainage patterns and ensure compliance with City of Laguna Beach “significant watercourse” ordinance1 for the property located at 2500 Glenneyre Street, Laguna Beach, California, and shown in Figure 1 below. The site plan2 and ordinance are exhibited in the appendix.

2  Demonstration of floodplain compliance, as codified in municipal code 25.38.3, which applies only to special flood hazard areas (SFHA), as defined by FEMA, thus does not have jurisdiction at this site, or
 Site drainage plan or water quality management plan (WQMP), which is typically performed by the general civil engineer.

A significant watercourse is not defined by a flood event of a specific recurrence interval, e.g., 2-, 10-, 25-, 100-year, et al. In fact, we are not aware of any documentation or justification that the mapped significant watercourses correlate to any standard or convention, e.g., drainage area, magnitude of flood, observed channel formations, etc. In the absence of any analysis, its delineation appears to be very subjective and lacking a consistent application in the City of Laguna Beach GIS. On a few occasions, Rivertech has requested from the City of Laguna Beach the basis of the mapped significant watercourses but have yet to receive a response, unfortunately.

Accordingly, we estimated flows for a range of recurrence intervals because there is no specific event that defines a significant watercourse, as stated above. A range of flows pragmatically encompasses the "significant" watercourse, which is an otherwise ambiguous term.

Furthermore, the hydrology model confirms the existence of a significant watercourse on the site and establishes a more refined delineation. As was the case with other studies that we have previously submitted to the City of Laguna Beach, the hydrology software employs a utility that delineates watercourses based on flow direction and accumulation using a digital terrain surface. This digital delineation, by itself, establishes the significant watercourse, irrespective of flow estimates.

Floodplain limits do not explicitly relate to the significant watercourse code. However, we performed the floodplain analysis because a riparian habitat is defined as adjacent to the watercourse and within the floodplain, which is relevant to the conservation and avoiding disturbance of riparian vegetation, per §25.50.030(D)(5). Furthermore, we demonstrated that the project improvements are outside of the floodplain limits, which is a case of going the extra mile. Further discussion is provided in the later sections of this memo.

According to the watercourse and property delineated in Figure 1, which was obtained from the City of Laguna Beach geographic information system (GIS) online portal4, the existing significant watercourse and 25-foot statutory setback traverse the property. There is an existing 24-inch corrugated metal pipe (CMP) storm drain pipe that collects runoff upstream of Glenneyre Street at the southern property line. The storm drain culvert inlet intercepts runoff from the

7.8-acre subarea draining to it, and conveys a portion of it to the 24-inch CMP that crosses under Glenneyre Street discharging into the downstream significant watercourse traversing 2553 Glenneyre Street. The storm drain pipe has capacity for the 10-year flow but flood events of greater magnitude will overtop the Glenneyre Street.

Hydrologic Modeling
We digitally delineated the watershed draining to the project site using 1m resolution digital elevation model (DEM), as depicted in Figure 2. Using the Watershed Modeling System (WMS) 3 Floodplain Management, Ordinance of the City of Laguna Beach, Chapter 25.38, https://ecode360.com/42900815#42900815 4 City of Laguna Beach GIS Map, https://lagunabeach.maps.arcgis.com/ 310

3 software, we determined the drainage area to the property downstream limit at Glenneyre Street (hydrologic node 40C) to be 7.8 acres.5 A wide scale map is exhibited in the appendix.

Using the Rational Method, as prescribed in the Orange County Hydrology Manual (OCHM), the peak flows were estimated.6 The hydrologic soil group within the watershed is C, with the supporting soil survey exhibited in the appendix. The land use within the watershed is comprised of single-family units. Using a random sample of parcels within the watershed delineated in Figure 2, the average parcel size is approximately 5,000 ft2, which is analogous to the single-family residential land use (8 – 10 dwellings per acre), as prescribed in OCHM (Figure C-4).

Figure 2. Watershed map.

Runoff is characterized as overland that eventually is concentrated and conveyed by street gutters and storm drain inlets and pipes. Table 1 summarizes the input of the hydrology model, which is shown in more detail in the appendix. The site is located in Basin 275B. The proposed development adds 0.071 acres of impervious surface to the site, which is reflected in the proposed condition for Basin 275B (see below). Hence, the proposed development increases the impervious surface by

1.6% in the watershed. The proposed condition is modeled as 68% impervious for Basin 275B, 5 Watershed Modeling System (WMS), Version 11.2.9, Aquaveo LLC, March 12, 2024. 6 Orange County Hydrology Manual, Orange County Environmental Management Agency, October 1986. 311

Most of the travel paths are overland in swales on residential lots with the remainder along streets, as can be seen in Figure 2 (and the wide format map in the appendix). We used a generalized trapezoidal shape with medium-to-dense vegetation (i.e., roughness coefficient, n = 0.060) to simulate these small shallow swales. Table 2 summarizes the hydrology results.

5 As can be seen in Table 2, the hydrologic model yields a 100-year peak flow of 53 ft3/s at hydrologic node 40C for the existing (pre-project) and proposed (post-project) conditions. Thus, no net increase in runoff occurs as a result of the implementation of the proposed development. The 25- and 10-year peak flows at node 40C are 40 and 33 ft3/s, respectively, for the existing (pre-project) and proposed (post-project) conditions, as well. The minute increase in impervious area coupled with routing and attenuation accounts for no net increase. The purpose of estimating these peak flows is to input into the hydraulic model, discussed in the following section, and to demonstrate that the proposed improvements do not impact the runoff that is conveyed by the significant watercourse.

Detailed hydrologic results and modeling output for the existing (pre-project) and proposed (postproject) conditions are presented in the appendix.

Hydraulic Modeling
We developed a hydraulic model of the significant watercourse using the HEC-RAS7 hydraulic modeling software for the purpose of depicting the flood potential. Figure 3 illustrates the topography, stream centerline, and hydraulic cross-sections (w/ corresponding river station label). The digital terrain was established using high resolution (1m) topographic data.8 Figure 3. Hydraulic model layout and topographic contours (5-ft intervals). 7 HEC-RAS, River Analysis System, Version 6.4, US Army Corps of Engineers, Hydrologic Engineering Center, Sacramento, CA, June 2023.

6 Hydraulic cross-sections were taken at an average of 25-foot intervals (but smaller intervals on the property), as shown in Figure 4 below, to establish a refined one-dimensional hydraulic model. Crosssections are delineated to a sufficient extent such that they contain the 100-year flows.

Execution of the HEC-RAS models for the 100-, 25- and 10-year flood events produced hydraulic results including flood elevations and floodplain limits, among other characteristics of flood flow.

Figure 4 illustrates the 100-year floodplain mapped on the most recent and higher resolution (1m) topographic data and field observations overlaid on the project site plan and reflects the watersurface elevation and top widths from the HEC-RAS output. The 100-year water-surface elevation adjacent to the pathways and stairs is 168.0. Moreover, the at-grade pathways and stairs, and all other elements of the proposed residential structure, are above the flood elevations and outside of the 100-year floodplain limits and thus do not obstruct the flood waters.

As can be seen, at the property downstream (southerly) limit, the 100-year flood elevation is 167.9 feet, where the undersized storm drain culvert produces a backwater effect. Due to the undersized culvert, flow overtops the roadway producing water-surface elevations over the road on the downstream and upstream side at 166.8 and 167.6, respectively.

At the upstream property limit, 100-year water-surface elevation is 190.5 feet. The contours represent 100-year flood elevations intervals (bold every 5 feet). The hydraulic cross sections (in red) are labeled with corresponding stations. It can be seen that the proposed improvements are outside of the 100-year floodplain. Flood events of lower magnitudes produce floodplains of lesser extents (i.e., the modeled 25- and 10-year).

7 The detailed results confirm that the runoff depth in the significant watercourse is typically a foot or less, except at the backwater immediately upstream of the 24-inch storm drain inlet, which is slightly more (i.e., 2 feet or less). Detailed hydraulic results, including HEC-RAS input and output, cross-section and channel profile plots, are exhibited in the appendix.

Verification of Results
The results of this study were verified to ensure that the calculated flows and floodplain limits are not underestimated. In a sensitivity analysis, the drainage area is held constant at 7.8 acres. Table 3 below provides a comparison of the modeled Orange County Hydrology Manual (OCHM) methodology (a modification of the Rational Method) and standard Rational Method, which was developed in 18899 and is used worldwide. The Rational Method is the most widely used method for storm drain design and analysis. The maximum scenario assumes the maximum theoretical value for runoff coefficient and rainfall intensity, which is a function of time of concentration. Five minutes is the lowest time of concentration that can be used with the Rational Method and corresponds to the maximum rainfall intensity. As can be seen in Table 3, the maximum value assumptions produce a 100-year flow that is less than the modeled flow which is another layer of conservativism. We found that the peak flow is much less sensitive to a variation in time of concentration compared to runoff coefficient and rainfall intensity. A time of concentration of 5 minutes is the minimum in the Rational Method, thus, 7 minutes is only slightly higher than the minimum Tc.

Notes: (1) OCHM, Figure B-3; (2) NOAA Atlas 1410; (3) OCHM uses impervious percentage to estimate runoff coefficient For floodplain management, flows are typically based on expected values (i.e., 50th percentile), which is the FEMA standard. However, in this floodplain analysis we applied the OCHM high confidence limits (85th percentile), which adds another layer of conservatism. The deliberate approach of applying conservative assumptions is to minimize the speculation of the variation of parameters, e.g., impervious cover (land use), time of concentration, et al., by establishing a 90th percentile or higher condition, in which the likelihood of underestimating flows and flood potential is very remote.

Recommendations and Conclusions
Based on our observations and review of the City-mapped significant watercourses, the drainage pattern of the significant watercourse does flow through the property. The proposed encroachment will act to hydrologically preserve, enhance or restore the significance of the watercourse.

Moreover, per 25.50.030 (4) and (5), the proposed encroachment, which is limited to the 25-foot setback on west side of the significant watercourse, is not likely to impair the functional purposes of the watercourse hydrologically; and will cause no physical disturbance of the watercourse at any time. The impact on the scenic and ecological purposes is beyond the scope of this report and is addressed in accompanying report submittals.

§ 25.50.030. Significant watercourses.
(A) Identification and Definitions. Significant watercourses are those which are depicted on the city's environmentally sensitive areas map. Significant watercourses include significant natural watercourses and significant modified watercourses. (1) "Significant natural watercourses" are those that are in their natural condition and which serve a distinct functional scenic or ecological purpose. As applied, ecological purposes include those related to wildlife habitats, particularly feeding, watering and breeding areas; and biotic habitat areas. Scenic purposes include those related to view corridors, density relief or general aesthetic appeal. Functional purposes include those related to hydrologic considerations.
(2) "Significant modified watercourses" are those that have been altered from their natural condition, but which continue to serve a distinct functional, scenic or ecological purpose as set forth under subsection (A)(1). Significant modified watercourses include those that have been channelized, piped, culverted or otherwise improved or diverted.

Significant modified watercourses are typified by the continuing presence of a topographic swale or depression and the ability to conduct overflow runoff. Significant modified watercourses that are restored may qualify for redesignation as natural watercourses.
(B) Demolition/Deletion Process. Proposals to add or delete watercourses from the environmentally sensitive areas map, or to change the status of significant watercourses shall be reviewed by the planning commission. Public notice shall be subject to the provisions of Sections 25.05.065 and 25.07.026. The planning commission shall make its determination based on its assessment of the watercourse as it relates to the criteria listed in subsection (A); provided, however, that a significant watercourse can be deleted only if it is determined that it no longer serves a distinct functional, scenic or ecological purpose. The decision of the planning commission may be appealed to the city council pursuant to Section 25.05.070. (C) Alterations Prohibited. Significant natural watercourses may not be filled in, diverted, culverted, lined or otherwise altered, except as necessary to enhance its natural characteristics or its functional or ecological purpose, or in the interest of public safety as determined and approved by the city engineer.
(D) Setbacks.
(1) Extent. A setback of twenty-five feet shall be maintained from both sides of the centerflow line (as determined and approved by the city engineer) of significant watercourses. The setback may be increased in the interest of protecting or mitigating stated environmental concerns as approved by the director of community development. (2) Disturbance of Vegetation Prohibited.
(a) No disturbance of the native vegetation within an established watercourse setback area is permitted at any time, except as part of a fuel modification program approved by the director of community development.
(b) The design review board may approve landscape programs within established City of Laguna Beach, CA
Downloaded from https://ecode360.com/LA4953 on 2025-09-17 318
setbacks designed to enhance or restore native riparian vegetation or the aesthetic character of the watercourse.
(3) Building and Structures Prohibited. No building or structure may be placed in an established setback from a significant watercourse, except for bridge structures for access purposes. Extension of decks, balconies and other portions of a structure are permitted to extend over an established setback, provided:
(a) There are no supports to the ground within the setback area; (b) The extensions may encroach no closer than fifteen feet in horizontal distance to the centerflow line of the watercourse.
(4) Encroachment Variances. Variances for the purpose of placing a building or structure within an established watercourse setback area, other than as permitted in subdivision (3) of this subsection may be granted only when the following findings are made in addition to those listed in Section 25.05.025(F).
(a) The proposed encroachment will act to preserve, enhance or restore the significance of the watercourse.
(b) The proposed encroachment is not likely to impair the functional, scenic and ecological purposes of the watercourse.
(5) Encroachment variances shall be subject to the conditions that no physical disturbance of the watercourse shall occur at any time; and that, where feasible, specified native riparian vegetation shall be replanted where disturbance of vegetation occurs during construction.
(E) Design Review.
(1) Design Review Required. All new development as specified in Section 25.05.040(B)(1) proposed on lots located wholly or partially within an established watercourse setback area shall be subject to design review. This requirement shall apply to development that would otherwise be exempt from design review pursuant to Section 25.05.040(B)(2); provided, however, that the review of development under such circumstances shall be limited to those features considered by the design review board to be related to the protection and aesthetic quality of the watercourse.
(2) Exemption. Development proposals on lots in the R-1 zone that support existing development and which are subject to design review only by reason of subdivision (1) of this subsection may be exempted from design review if the director of community development determines that the project is not likely to have any adverse environmental impacts on the watercourse and their restoration of the watercourse, if altered or disturbed, is not feasible and appropriate. In granting such exemptions, the director of community development may invoke conditions as determined necessary for the protection of the watercourse.
(3) Restoration. In cases where previous development, improvements or other alterations have caused deterioration or degradation of the natural condition of a watercourse, the City of Laguna Beach, CA

Based on its determination, the board may impose conditions for specified restoration activities.
(F) Temporary Fencing. Significant natural watercourses shall be temporarily fenced as required, during construction at locations determined by the city engineer and the director of community development to assure the preservation of the watercourse and vegetative cover.

The fence shall remain in place until construction is complete, at which time it shall be removed. The required setback and channel shall not be used for storage or dumping of materials.

Non-mountainous rainfall intensity regression equation: I(t) = a*t^b Regression 'a' factor = 11.995
Regression 'b' factor = -0.566
Mountainous rainfall intensity values
5 min = 7.560
30 min = 2.080
60 min = 1.510
180 min = 1.030
360 min = 0.800
1440 min = 0.370
Note: Mountainous rainfall intensity values are
calculated by interpolating between known
intensity values.

Non-mountainous rainfall intensity regression equation: I(t) = a*t^b Regression 'a' factor = 10.209
Regression 'b' factor = -0.573
Mountainous rainfall intensity values
5 min = 6.000
30 min = 1.680
60 min = 1.220
180 min = 0.830
360 min = 0.650
1440 min = 0.290
Note: Mountainous rainfall intensity values are
calculated by interpolating between known
intensity values.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.

Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.

Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.

Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.

Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.

Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.

Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.

Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The program used critical depth for the water surface and continued on with the calculations.

Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross section. This may indicate the need for additional cross sections.

Warning: During the standard step iterations, when the assumed water surface was set equal to critical depth, the calculated water surface came back below critical depth. This indicates that there is not a valid subcritical answer. The program defaulted to critical depth.
