RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 2 of 28 1. Introduction In 2012, The City of Ottawa and three conservation authorities (Mississippi, Rideau and South Nation) initiated a program for flood risk mapping within the boundary of the City. A five-year plan for mapping a number of high priority rivers and streams was made. As part of this program, the RVCA has identified 12 stream reaches, where the existing mapping would be updated or mapping will be created for the first time. Historically, the Rideau River from Poonamalie Dam to the Rideau Falls has been segmented in to five reaches for flood mapping studies: 1) Rideau River (Hogs Back to Rideau Falls) 2) Rideau River (Hogs Back to Kars) 3) Rideau River (Kars to Burritts Rapids) [this study] 4) Rideau River (Burritts Rapids to Smiths Falls) 5) Rideau River (Smiths Falls to Poonamalie Dam)

The first three reaches are within the City of Ottawa and were therefore identified for updating during this program. Updating of the first reach (Hogs Back to Rideau Falls) has already been completed (RVCA, 2016). Work on the second reach is nearing completion and a project completion report is being produced concurrently (RVCA, 2017b). This report deals with the third reach (Kars to Burritts Rapids). The middle three reaches are in need of updating and it was decided that a single, comprehensive hydrological analysis done for the entire Rideau River will be a logical approach. This single hydrological study has now been completed (RVCA, 2017a), which should be read along with the present report. The flood quantiles derived from the hydrology report have been used here (and will be used elsewhere) for flood mapping purposes along the Rideau River. This report deals with the flood risk mapping of the third reach of the Rideau River (Kars to Burritts Rapids). The last mapping study (Robinson, 2003) of this reach is now 14 years old. Changes in the landscape have taken place along the shoreline and floodplain, such that the plotted flood limits in some locations may no longer accurately depict areas that are presently flood prone under regulatory flood conditions. It has been deemed desirable and necessary by the City of Ottawa to produce updated flood line mapping, to facilitate the

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 3 of 28 implementation of the natural hazards policies of its Official Plan and the associated zoning by-laws. A funding contribution from the City has enabled the RVCA to prioritize this project within its ongoing, watershed-wide program of flood risk assessment and flood plain delineation. This report provides a summary of the analytical methods used and underlying assumptions applied in the preparation of flood plain mapping for the Rideau River from Kars to Burritts Rapids (Figure 1). The project has been done in accordance with the technical guidelines set out under the Canada-Ontario Flood Damage Reduction Program (FDRP) (MNR, 1986), and the technical guide for the flood hazard delineation in Ontario (MNR, 2002) as laid out by the Ontario Ministry of Natural Resources. It also conforms to the ‘generic regulation’ guidelines of Conservation Ontario (2005). The 1:100 year flood lines delineated here are suitable for use in the RVCA’s regulation limits mapping (as per Ontario Regulation 174/06) and in municipal land use planning and development approval processes under the Planning Act. The Robinson (2003) mapping has been used by RVCA for regulatory purposes since 2003. The present mapping, when endorsed by RVCA’s Board of Directors, will supersede the 2003 Robinson mapping.

Study Area The Rideau River, from Kars to Burritts Rapids, has no branches and is thus the only stream reach mapped during this study. This 32 km reach extends from the upstream side of Regional Road 6 or Roger Stevens Drive at Kars to the downstream side of the Burritts Rapids Dam (Figure 1). The area mapped is located mostly within the City of Ottawa. However, a 26 km reach separates the City from the County of ; thus mapping of this part also affects North Grenville. The river goes through sparsely populated rural areas. There are a few flood vulnerable areas such as those near the Village of Kars, Lorne Bridge Road, Fenell Lane, Baxter Conservation Area, Fairmile Drive, Hilly Lane and Becketts Landing.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 5 of 28 3. Previous Studies Two flood plain mapping studies that included the reach from Kars to Burritts Rapids have been carried out in the past (James F. MacLaren, 1976; Robinson, 2003). The first study was conducted by James F. MacLaren (1976), with a focus on the reach from Kars to Smiths Falls. Flood frequency analysis was done using available streamflow data at Long Island (1949-1975; 27 years), Merrickville (1942-1975; 34 years) and Poonamalie (1944-1975; 32 years). The 1:100 year floods at these three locations were estimated at 14400, 5300 and 5000 cfs (407.8, 150.1 and 141.6 cms) respectively. Flows at other locations were computed by interpolating flows as a linear function of drainage area. The contribution of Creek was estimated as 8600 cfs (243.5 cms) and was added at the confluence. The determination of the 1:100 year flood profile was based on two components. First, the headwaters upstream of water control structures were computed using the information provided by Park Canada’s Office. Second, the channel profiles upstream were computed using the RBACK computer model (developed by James F. MacLaren and based on the standard step method). Flood lines were then plotted on photo-mosaic sheets. The second attempt to map the Rideau River from Kars to Burritts Rapids was made in early 1990s. This project was commissioned in 1992 and the final report by Robinson (2003) was preceded by a number of interim reports. Different methodologies were tried and many challenges faced; but at the end, the approach based on flood frequency analysis at gauge locations and flow transposition – first advocated by Robinson (1984) – was adopted. A frequency analysis of the streamflow data from 1948 through 1989 at Below Manotick gauge was done, and the three parameter log-normal (3PLN) distribution was selected for conservatism and also for consistency with past studies. It is not clear if the data at the Ottawa gauge was revised. However, it appears that the flood quantiles at Ottawa and Below Manotick were used for estimating the flows at upstream locations by area pro-rating (thus making it an extrapolation rather than interpolation). The details of the hydrological calculations are scattered in various interim reports, but a 1993 report (Robinson, 1993) contains the summary. At the end, however, design flows from Dillon (1989), which were really taken from Robinson (1984), were finally chosen for flood mapping purposes. The estimated flows were then used in the

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 6 of 28 HEC-2 model for water profile computation. Flood lines were plotted on 1:2000 and 1:5000 scale topographical maps. It is noted here that the James F. MacLaren’s (1976) mapping work was extended in 1983 to include major tributaries and is documented in James F. MacLaren (1983) report. Spring floods of nine tributaries were estimated. And the spring floods were used to calculate the flood levels along the tributaries. The hydraulic computation was done using the HEC-2 model, and the floodplain plotted on phot-mosaic sheets. Updating the mapping along these tributaries is not within the scope of the current study, and therefore, the present study has no impact on them.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 7 of 28 4. Topographical Mapping LIDAR: High quality topography is the key to high quality flood risk mapping. Digital elevation models were derived from LIDAR data procured by the City of Ottawa. The LIDAR was flown in April 2007 and August 2012. This data set has a density of about 7 to 8 points per square meter, and an estimated vertical accuracy of 0.10 m (Airborne Imagery, 2013). The City also provided 0.25 m contour lines that were derived from LIDAR data. However, we only used the LIDAR points (spot heights) directly for this study, and the contour lines were never used. In some places, the LIDAR data was missing along the water line or were obscured by trees and shrubs. RVCA staff carried out ground surveys during 2014 and 2015 to collect data to augment the LIDAR data for the purposes of flood line delineation. The accuracy of the LIDAR data was checked in the field by RVCA staff in April-May 2015. The true elevations of features on the ground that are identifiable on the mapping were determined using RVCA’s survey grade GPS equipment (Trimble R8), and compared with the elevations indicated by the LIDAR spot heights, to determine that any differences between mapped and true elevations were within the accuracy prescribed by the FDRP standards. In total, 300 spot heights were verified (see Table B.1 and Figure B.1 in Appendix B). As described in the FDRP guidelines (MNR 1986), the spot height checks are considered satisfactory when 90% of the data points are within 0.33 m of the field measurement. As shown in Table B.1, this criterion has been adequately met1. On average, the spot heights are within 4.9 cm (Figure B.2). At the few locations where these criteria are not met, changes to the landscape since the date of air photo have been identified as the probable cause of the discrepancy. Data at these locations were disregarded in the DTM verification. In the southeast portion of the study area, floodplains extended beyond the 2012 LIDAR coverage, which extended only about 500 m south of the Rideau River. High

1 FDRP (1986) Manual also specifies criteria for checking contour crossings. However, in this study we used only LIDAR spot heights, not contour lines. Therefore, we did not check the accuracy of contour lines supplied by the City of Ottawa.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 8 of 28 quality DTM based on 2001 aerial photography, which met FDRP (1986) specifications, was used in this area. Drape Imagery: The Drape imagery was collected in April-June 2014 with a horizontal accuracy of ±0.5 metre. This high quality colored photo clearly shows the rivers, creeks, land use, houses, buildings, roads, infrastructure, vegetation and other details. 2011 Aerial photo: The 2011 aerial photo was also available from the City of Ottawa. It is accurate, sharp and in colour, and shows various natural and man-made features clearly. Building footprint: The ‘building footprint’ layer was provided by the City of Ottawa for the area inside the urban boundary. It enables us to accurately draw flood lines around buildings. This data layer contained information collected over a number of years.

Hydrological Analysis The hydrological analyses to support this study have been documented in an accompanying report (RVCA, 2017a), and are not repeated here. Suffice it to say that the methodology was based on a thorough review of past studies. Our current methodology for estimating flood quantiles along the Rideau River consists of the following components: o Estimating and using instantaneous flows o Converting ‘regulated flows’ to ‘naturalized flows’ by using the Robinson (1984) methodology o Testing streamflow data for suitability for flood frequency analysis (homogeneity, independence, randomness, and trend) o Using standard flood frequency analysis where long enough streamflow record is available (gauge locations) to estimate flood quantiles o Using area pro-rating to transpose flood quantiles from gauge locations to other locations o Using the hydraulic model (HEC-RAS) to determine the flow split where multiple branches are present

Once we settled on this approach, the available streamflow data and watershed characteristics determined to a large extent the eventual outcome of this analysis, i.e., the flood quantiles. Table 1, taken from RVCA (2017a), shows the flood quantiles that were computed for flood mapping purposes along the Rideau River. Table 2 lists the exponents which were determined from streamflow data and were used in computing flows at ungauged locations. Table 3 shows the flows that were used for hydraulic computation (HEC-RAS modeling). Figures 2 and 3 illustrate the spatial distribution of flood quantiles and their relative magnitude.

Hydraulic Computations 6.1 HEC-RAS Model Following standard procedures (MNR, 1986; USACE, 1990, 2010), a steady-state hydraulic model of the Rideau River was built. The steady state HEC-2 model developed by Robinson (2003) was converted to HEC-RAS and updated to present conditions. The HEC-RAS software (version 4.1.0) developed by the US Army Corps of Engineers (USACE, 2010) was used. It uses the same back water calculation procedure as HEC-2 (USACE, 1990), which has been the industry standard since the 1970s, but with improved data processing and graphical capabilities. Cross-Sections: The cross-sections used in the modeling were imported from Robinson’s (2003) HEC-2 model files. These cross-sections (95 in total) were based on the original 1970 bathymetry generated by sounding technique by Canadian Hydrometric Service (CHS). The above-water part of the cross-sections was extracted from 1:2000 scale topographical mapping generated from aerial photography collected on 26th April 1985. This data was supplemented by field data collected by Robinson (2003) and RVCA staff at that time. The above-water portion of cross-sections matched well with recent LIDAR data and was deemed to be suitable for the current study. Survey work to verify the representativeness of the below-water portions of the cross-sections was considered to be beyond the scope of the current project. In total, 95 cross-sections were used in our HEC-RAS model. Figure 4 shows a schematic of the HEC-RAS model. Figures 9(a-e) show the cross-sections in greater detail, along with the computed Regulatory Flood Levels (RFLs) and flood risk limits. The spacing between and the alignment of river cross-sections within the model were reviewed and adjusted as necessary. Channel Roughness: These values were directly taken from Robinson’s (2003) calibrated HEC-2 model. The Manning’s roughness coefficient was generally between 0.030 and 0.035 in the main channel, and was 0.08 for most of the overbank areas (a tabular listing is included in Appendix A). These values were consistent with standard values, such as those recommended by Chow (1959). As will be seen later in this report, these values were found satisfactory and no further adjustment was necessary.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 11 of 28 Rating Curve: Rating curve at the Rideau River Below Merrickville gauge location was obtained from Water Survey of Canada (WSC) (Figure 5). This rating curve was outside the study reach (Kars to Burritts Rapids) and thus could not be directly used in HEC-RAS model verification. But it would be useful for mapping the next reach (Burritts Rapids to Smiths Falls). Bridges/Structures: Within the study area there are four bridges and one dam (Tables 4 and 5). As-built drawings for all the bridges within the reach were obtained from the City of Ottawa. Bridges in the Robinson study were not directly added to the model since the structures were wide and high with no possibility of affecting the flood flow. The bridges were instead represented as cross-sections with encroachments to represent bridge abutments2. Only the Roger Stevens Drive Bridge was included in the hydraulic model in order to be consistent with the RVCA’s (2017b) model downstream (Kars down to Hogs Back). As-built information for the Burritts Rapids Dam was obtained from Parks Canada’s Rideau Canal Office, Smith Falls and from Acres (1994) report. Tables 6 and 7 lists the cross-sections, bridges and dams that were modified from Robinson’s (2003) during the course of this study, and the reasons for doing so. The design flows from the hydrologic analysis (discussed above), with return periods ranging from 2 to 500 years (Table 1), were used in the HEC-RAS model. Table 3 shows the flows that were input to the HEC-RAS model. At the downstream end of the HEC-RAS model, the model was extended about 1.5 km downstream of Regional Road 6 Bridge. The boundary conditions, i.e., simulated water levels at the downstream end (cross-section -1460), were taken from the recent HEC-RAS model for the downstream reach (from Hogs Back to Kars; RVCA, 2017b). Table 8 lists the boundary conditions for various flood events. All dams were assumed to be fully open during flood conditions. This is the current policy of Parks Canada, the owner and operator of the dams3.

2 This was found to be an acceptable method when scrutinized. When the bridges were modelled using the bridge design editor in HEC-RAS, a water level variation of only 1 cm was found.

3 In a meeting between RVCA and Parks Canada staff on 12 March 2015, the current operating policies for the dams along the Rideau Canal were clarified and confirmed by Parks Canada staff. During flood events, Parks Canada fully opens the dams and allows ‘free flowing’ condition at all structures.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 12 of 28 Once the model was set up, the computed profiles and other parameters were scrutinized to assess the reasonableness of model outputs. Special attention was given to the computed water level and energy profiles near bridges. Adjustments of model parameters – mainly the channel resistance and contraction and expansion coefficients – were made as necessary.

6.2 Model Verification If possible, hydraulic models are generally calibrated and validated before being accepted as representative of the river system being modeled. In this case, our HEC-RAS model is based on Robinson’s (2003) HEC-2 model, which was calibrated and found satisfactory at that time. Therefore, we first tested our HEC-RAS model, without significant changes, to see if it works. We found that it works well, and conforms to available data (collected both during Robinson study and since then). By virtue of being a slightly modified version of the well calibrated Robinson’s (2003) HEC-2 model, the current HEC-RAS model needed almost no adjustment to be considered calibrated. The verification was done in the following ways: o By comparing water levels during 6 April 1999 flood event o By comparing water levels during 11 April 2014 flood event o By comparing water levels during 4 April 2015 flood event

The HEC-RAS model is able to match observed water level data very well for the 1999 event that were also used by Robinson (2003)4. Table 9a indicates that the matching was within 2-13 cm. The 6 April 1999 had a return period between 2 to 5 years. The flood of 11 April 2014 had a return period of about 5 years. This is a well- documented large flood in recent years. The HEC-RAS model simulated the water levels within 1-10 cm (Table 9b). These two events of 1999 and 2014 were used to verify the model and it was concluded that the model was well-calibrated. After this, however, information was also collected during 2015 spring, and we decided to utilize this additional information.

4 This is the only event that Robinson (2003) used for calibration.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 13 of 28 The flow on 4 April 2015 was far below of what can be considered a flood. Nonetheless, it allowed an additional check of the model. The model slightly overestimated the water levels by 16-18 cm (Table 9c). This overestimation may be attributed to the modelling of dam parameters. The dams have been modeled for free flow condition. But on 4 April 2015, not all dams were in free flow condition; and therefore, stop logs and gate openings were added to model them properly. During the verification runs, the dam settings were based on the information supplied by Parks Canada5. This adjustment to the dam conditions without adjusting the other dam parameters, such as contraction and expansion coefficients, may have led the model to overestimating water levels. Figure 6 shows the summary of all three verification events. Our model was able to simulate water levels within 1-13 cm for relatively large flood events. This establishes that the model is good for flood mapping purposes. It is also noted that the model has a slight degree of conservatism. This confirms that our intention of calibrating the model to match observed data as closely as possible, but with a slight degree of conservatism, has been achieved. It has traditionally and widely been accepted that the calibration process is not meant to force the model to fit all observations, but to match the computed water surface profile to observed water levels within a certain limit. A rule of thumb used by the USACE (US Army Core of Engineers) specifies good calibration when the model predicts elevations within 30 cm of observation (Heastead Methods, 2003; Bentley Systems 2007); whereas FEMA (US Federal Emergency Management Agency) suggests a 15 cm tolerance (FEMA, 2009). Our model satisfies both criteria. Our approach of slight conservatism (a combination of hydrologic and hydraulic computations) is also congruent with the current notion of the Precautionary Principle, which applies when there exist considerable scientific uncertainties about causality, magnitude, probability, and consequences of different course of action (UNESCO, 2005). The Precautionary Principle is also a key policy of Environment Canada6.

6 Canada’s environmental policy is also guided by the precautionary principle and is reflected in the Federal Sustainable Development Act which states that the Minister of Environment must “develop a Federal

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 14 of 28 Based on the above reasoning, the model is considered well calibrated and suitable for flood hazard mapping7.

6.3 Computed Water Surface Profiles Once calibrated, the model was run with the design floods. The 1:100 year computed water surface elevations and other parameters are shown in Table 10. A few typical water surface profiles and all cross-sections are included in Appendix A. Computed water surface elevations for various flood events with return periods ranging from 2 to 500 years are presented in Tables 11 and 12. It should be pointed out that the model has been built and calibrated based on observed flood events in the 130- 320 cms range (at Below Manotick gauge) occurring during spring freshet. Caution should be used when applying this model to simulate water surface profiles for flows outside this range, or for flows that occur during other seasons of the year. Such water surface profiles – simulated using the same parameters, especially the Manning’s roughness coefficient – would be only approximate, and should be used with caution. This is because the river roughness can vary with flow magnitude (with higher resistance associated with lower flows) and with the time of the year (as related to the presence of instream vegetation). It is also acknowledged that the 1:100 year flood is much larger than the flow range used for calibration. However, use of the same calibration parameter (Manning’s roughness calibrated for 130-320 cms flow range) for the 1:100 year flow will result in a very slightly higher (conservative) flood level. This approach is reasonable and is widely accepted as a standard practice.

Sustainable Development Strategy based on the precautionary principle”. The precautionary principle states that: “Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation”. In other words, the absence of complete scientific evidence to take precautions does not mean that precautions should not be taken – especially when there is a possibility of irreversible damage (Environment Canada, 2010).

7 While we consider the model good enough for the purposes of floodplain mapping, we also recognize that further model adjustment/modification may be necessary for other purposes. It all depends on the purpose of the modeling and the features and phenomena a model is meant to capture. We therefore caution against using this model for other purposes without first confirming its suitability.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 15 of 28 In cold climate areas like Ontario, floods may occur with or without ice jam. Here we have only analyzed the ice-free or open water condition. Ice-induced flooding has not been looked at because we are unaware of any ice-related flooding that caused significant concern in this area (Kars to Burritts Rapids). Downstream of Hogs Back, ice jams have historically occurred and have been managed by ice cutting/blasting for at least the last one hundred years.

6.4 Sensitivity Analysis Flood quantiles have the highest degree of uncertainty in our computation and is most likely to affect the water surface profile. Therefore, we decided to test the sensitivity of water surface profile to flow variation. The sensitivity analysis was conducted to determine how much the computed water surface elevations will vary with changes in the value used for the 1:100 year discharge. Six flow conditions were tested:

• 1:100 year flow increased by 5% • 1:100 year flow increased by 10% • 1:100 year flow increased by 20% • 1:100 year flows decreased by 5% • 1:100 year flow decreased by 10% • 1:100 year flow decreased by 20%

Figures 7 and 8 show the computed water surface profiles and the differences in computed water levels for each condition. Figure 7 indicates that the computed water surface elevations are nearly horizontal and change rather uniformly over the entire length of this river reach. The sensitivity analysis indicates that the computed water level can vary by less than 0.25 m for a 10% variation in flow along most of the river reach, which is typical in the hydrologic estimation of design flow. For a 20% increase in flow, the water level can go up by 0.40 to 0.45 m. The sensitivity analysis provides an indication of the potential effect of changes in the expected flood flows that might result from anthropologic intervention in the watershed or from natural variability such as climate change.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 16 of 28 7. Selection of Regulatory Flood Levels As per Section 3 of the Provincial Policy Statement under the Planning Act (MMAH, 2005, 2014), the regulatory flood in Zone 2, which includes the RVCA, is the 1:100 year flood8. Depending on the local hydraulic conditions, the computed water surface elevation, the energy grade or a value in between is generally taken as the Regulatory Flood Level (RFL). Engineering judgment is applied to recommend an appropriate value for the regulatory flood level at each cross-section, using the model outputs and considering hydraulic characteristics of the river reach, and the inherent limitations of numerical modeling. When the stream velocity is relatively low and varies only gradually over relatively long river reaches, the water surface can generally be taken as the RFL. However, near bridges, culverts and other water control structures, and on steeper reaches where streamflow velocities are higher, and may change more abruptly, the computed water surface elevation may be substantially lower than the energy grade level, with the possibility that the water level may rise to the energy grade near obstacles and irregularities in the channel profile or cross-section which may not be represented in the hydraulic model. In such cases, the regulatory flood level is generally based on the computed energy grade as a conservative approach, given that the numerical model is less likely to be a true representation of reality in such situations. Another possible situation arises when the computed water surface profile is undulating, with downstream water levels occasionally higher than upstream levels. When this occurs, it is more often an artifact from the simplifying assumptions of the modeling scheme than a reliable prediction of the actual differences in flow velocity and depth from one cross-section to the next. Accordingly, the regulatory flood level at the upstream cross-section is taken to be equivalent to the downstream water surface elevation in these situations. Setting RFL equal to the energy grade resolves this problem.

8 Review of historical water level indicates that it never exceeded the estimated 1:100 year flood level. In a recent study on the lower most reach from Hags Back to Rideau Falls (RVCA, 2016), it was found that the highest recorded water level at Carleton University gauge (60.35 m on 28 March 1976) was lower than the estimated 1:100 year flood level of 60.75 m. Furthermore, during subsequent studies on the upstream reaches (Hogs Back to Kars, and Kars to Burritts Rapids) (RVCA, 2017a, 2017b), the same was found at Manotick gauge (81.01 m recorded vs. 81.80 m estimated flood level) and at Becketts Landing (86.76 m recorded vs. 87.31 m estimated flood level). Therefore, the 1:100 year flood is the appropriate mapping standard for the Rideau River.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 17 of 28 In all cases, the RFL is always between the computed water level and energy grade line. Hence, for the sake of simplicity and consistency, the energy grade elevation is often used as the RFL as a standard practice in delineating flood hazard areas. For the present study, the regulatory flood levels were set equal to the computed energy grade and are tabulated in Table 10, along with the computed water surface elevations and energy grades at each cross-section in the model.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 18 of 28 8. Flood Line Delineation 8.1 General Once the RFLs are established, the plotting of 1:100 year flood lines or flood risk limits is a relatively straightforward matter. Given the topographical information in the form of LIDAR spot heights, the inundated area below the RFLs can be easily delineated manually or by using automated computer programs. In the present case, it was done manually with a focus on areas with complex topography, infrastructure, and overbank flow paths. The raw LIDAR spot heights were extensively used in the plotting the flood risk limit. Field surveys were conducted by RVCA staff in 2015 to verify hydraulic connectivity through culvert openings and flood prone areas. This information (Table 13) was used in plotting the flood risk limit near culverts. The record of site-specific information associated with RVCA’s regulatory approval process was compiled since 2012 (Table 14). At none of the locations did the site-specific information warrant an adjustment of the flood lines. Available as-built drawings, building layer, and aerial photographs were used to determine the flood risk limit. Special attention was paid near the outfalls of smaller tributaries to the Rideau River within the study area, since such areas are subjected to flood risk from two sources (backwater from a high Rideau River level, or an extreme flood event on the tributary). The flood plain limits on tributaries have been plotted based only on the flood elevation of the Rideau River – that is, assuming a horizontal water surface profile up along the tributary and an insignificant flow in the tributary itself. Caution needs to be applied when interpreting the flood line information produced in this study in the review of any development or watercourse alteration proposals on the downstream reaches of the tributaries – by taking into consideration the potential effect of high flows originating in the tributary watershed, possibly in combination with high water levels on the Rideau River in an appropriate manner.

Recently, RVCA has consolidated a few rules for drawing flood lines in the vicinity of buildings (Appendix C), which have been followed in this study. Due to the limitations of the data and methodology used in the current mapping done at a large scale, and the small degree of (inevitable) subjectivity in drawing flood lines around buildings at a smaller scale, RVCA recommends that, should the need arise for more accurate flood line delineation near buildings, site-specific information be taken into account when dealing with flood risk at these locations. It is the practice of RVCA to refine flood lines when more accurate information becomes available.

8.3 Islands in the floodplain Presence of small islands, especially those associated with septic beds, within the floodplain also requires special attention. Recently, RVCA has decided to show small islands with an area less than 1000 m2 as flood risk area (Appendix C) This guidance was followed during this study.

8.4 Flood mapping data in GIS The regulatory flood lines and cross-sections have been incorporated as separate layers in RVCA’s Geographical Information System (GIS). In this system, one can view the flood lines, cross-sections, design flow, water level, energy grade, RFL, and other computed parameters. The flood lines can be overlain on the aerial photography or any other base mapping layers that are in the system and at any scale that suits the user’s need. The regulatory flood line layer is maintained, and updated as required according to the established procedures of the RVCA (RVCA 2005). Figures 9(a-e) shows the flood risk limits as delineated in this study. At all cross- section locations, the RFL is indicated. The general surrounding and land marks are also included for easy referencing.

Project Deliverables The key information or knowledge products generated from this project are: 1) The Flood Mapping Report (this Technical Memorandum) – which summarizes the analytical methods that were used and the underlying assumptions 2) The flood risk limit lines in GIS format (shape files) – identifying the extent of lands which are considered to be vulnerable to flooding during a regulatory flood event (1:100 year flood on the Rideau River) 3) The HEC-RAS model files (input and output) 4) The position and orientation of cross-sections used in the HEC-RAS model, in GIS format (shape files) – which, when used in conjunction with the HEC-RAS model output files, informs the user as to the estimated 1:100 year water surface elevation and the regulatory flood level for any location in the study area

A “documentation folder” containing working notes and relevant background information accumulated during the study process is maintained by the water resources engineering unit within RVCA’s Watershed Science and Engineering Services Department.

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 21 of 28 10. Closure The hydrotechnical and cartographic procedures used in this study generally conform to present day standards for flood hazard delineation, as set out in the MNR’s Natural Hazards Technical Guide (MNR, 2002). The resulting 1:100 year flood lines are suitable for use in the RVCA’s regulation limits mapping (as per Ontario Regulation 174/06) and in municipal land use planning and development approval processes under the Planning Act. The water surface profiles generated in the study will also be useful in the flood forecasting and warning services provided by the RVCA.

Buildings and Islands in Floodplain – RVCA Policy

RideauMapping(KarsToBR).docx 7/18/2017 3:17:05 PM Page 28 of 28 Ferdous Ahmed

From: Ewan Hardie Sent: Wednesday, June 29, 2016 10:35 AM To: Ferdous Ahmed Subject: Buildings in the Floodplain Guidelines

Hi Ferdous, As discussed at recent meetings please consider the following guidelines when undertaking floodplain mapping projects

Effective June 13th 2016, when plotting floodlines RVCA staff will use the following guidelines in order to apply a conservative approach to the delineation of the regulatory floodplain, specifically in areas that have buildings that are in the floodplain or affected by the floodplain: 1. Include any buildings in the floodplain that have any part of the footprint touching the floodplain. This is done to be conservative based on the lack of knowledge on the conditions around the buildings: soil conditions, window wells, walk out doors, building egress are all not known at the time of a floodplain mapping study so it is wise to adopt a conservative approach and include building footprints in the floodplain. 2. With regards to dry islands in and around buildings, islands will be removed if they did not meet the minimum mapping unit acceptable for the data. An envelope of 2 metres around building footprints is to be considered. If the floodplain comes close to or is in this 2m building envelope the entire envelope should be included in the floodplain. This approach is also consistent with the above approach (building footprints) in that the lack of knowledge of the conditions around the building forces the uses of a conservative approach, which is to remove the islands 3. In cases where a building has been included in the floodplain (because of the above criteria), the adjacent building will need to be included in the floodplain as well because of a lack of data in between the buildings and/or the 2m building envelope rule. 4. In the case of townhome or connected type buildings and the floodplain touching the foundations, the building footprint should be included up to the next visible unit partition where the elevation changes

From: Ewan Hardie Sent: Thursday, July 6, 2017 5:12 PM To: Ferdous Ahmed Cc: Brian Stratton Subject: Floodplain delineation guidance

Good Afternoon Ferdous,

As discussed here is the documentation of the guidance that was given to RVCA staff when it comes to plotting floodlines using LiDAR data for this most recent project.

Guidance:

When delineating the regulatory flood water levels, RVCA staff will follow a precautionary principle to include island areas in the floodplain that are up to 1000 square metres.
