INTRODUCTION f��rv� / This section describes the hydrologic and hydraulic methodology used for investigating and evaluating the flooding problem. The analysis included the development of a hydrologic model using procedures outlined in the King County Surface Water Design Manual (KCSWDM) (King County, 1990). The hydrologic model was developed to estimate the runoff rates and volumes to the problem area (Basin A) as well as the other basins of interest (Basins B through D). As previously noted, evaluation of Basins B through D was investigated because routing Basin A flow through the drainage system along NE 27' Street and Kennewick Place NE is a potential solution to the problem. The hydraulic analysis included the development of a King County BWPIPE model of the existing drainage system along as NE 27' Street and Kennewick Place NE which discharges to May Creek. Important assumptions made during the hydrologic and hydraulic modeling as well as the results are included in the following paragraphs. B. HYDROLOGIC METHODOLOGY Peak runoff rates and runoff volumes for each subbasin were estimated using the SBUH method utilized in the KCSWDM HYD computer program. The HYD model was used to predict the system's hydrologic response for the 2-, 10-, 25-, and 100-year 24-hour storm events for both current and future land use conditions. The precipitation depths and rainfall distribution used in the analysis are as follows: 2-year/24-hour: 1.98 inches SCS Type 1a distribution 10-year/24-hour: 2.89 inches SCS Type la distribution 25-year/24-hour: 3.40 inches SCS Type la distribution 100-year/24-hour: 3.85 inches SCS Type la distribution Figure 3 illustrates the HYD model schematic that shows routing of the subbasin flows. Nodes shown on this Figure as well as on Figure 1 reflect the summation of flows from two or more subbasins as they are routed downstream. Other back-up information such as a summary of subbasin characteristics, runoff curve number computations, time of concentrations, and model-summary tables are included in Appendix B. X1159121.998 9/24/97 SECTION 3 Runoff Curve numbers are input variables that the HYD model uses to calculate runoff from different types of land use/vegetation types. Runoff Curve numbers were generally chosen in accordance with Table 3.5.2B of the KCSWDM. For existing land use conditions, it was assumed that all impervious areas are effective (i.e., they are connected to the drainage system). For future land use conditions, a reduction factor was applied to account for the on-site stormwater infiltration and detention systems that will be associated with new development. These on-site facilities would tend to mitigate the increase in the peak runoff rates (and volumes if infiltration systems are used) from new developments. The reduction factor was made by reducing the percent impervious for new development by 40 percent and considering these areas to have runoff characteristics similar to open spaces/yards in good condition (refer to Table 3.5.2B in Appendix B). Times of concentration were calculated in accordance with the 1990 manual. A summary of the existing land use HYD model parameters for each subbasin is given in Table 2. Table 3 provides a summary of the future land use HYD model parameters for each subbasin. Two HYD reservoirs were included in the model analysis. A HYD reservoir is used to simulate a detention and/or infiltration system and is described in the model by a stage/storage/discharge relationship. The first HYD reservoir reflects the stormwater detention/infiltration system constructed as a part of the Pollis Estates development, located on East Aberdeen Avenue NE at NE 21st Street. The input data for this system was taken from the developer's as-built drawings. The infiltration pond at the problem area, located on the west side of Aberdeen Avenue south of NE 24' Street, was also represented in the model with an infiltration rate of 0.003 inches per minute. It is also noted that about a third of the pipe network draining the vicinity of NE 23'd Street, Blaine Avenue NE, and Camas Avenue NE within subbasin A4 is made up of perforated pipe. The model simulations do not include an allowance for infiltration through this system because this system is fairly old (built in 1981) and the extent of infiltration occurring is uncertain. One change in the model subbasin areas was made between the current and future land use simulations. This change relates to subbasin A8. A small portion of this subbasin, designated as subbasin A8a on Figure 1 drains to a closed depression west of Aberdeen Avenue NE and does not presently drain to the problem area. For future land use conditions, it was assumed that this area would develop such that runoff from the area would be connected to the system along Aberdeen Avenue NE. Table 4 gives a summary of the HYD model results for current and future land use conditions. The model results also show that the capacity of the existing stormwater infiltration system in Aberdeen Avenue NE is exceeded for all of the flood events modeled. This is consistent with reports from the City that the existing stormwater infiltration system overflows to the lift station during any large event, often more than once a year. 3-2 R. W. Beck 9/24/97 X1159121.998 ' S HYDROLOGIC AND HYDRAULIC ANALYSIS fIt is important to note that the HYD computer program methodology for hydrograph routing does not simulate flood flow attenuation when a ' conveyance system is undersized (resulting in surcharged flow and associated flood storage) unless the system is specifically modeled as a pond. Nor does the program incorporate channel routing algorithms, which tend to attenuate peak runoff rates. Consequently, the analysis tends to be somewhat conservative. ' C. HYDRAULIC METHODOLOGY To evaluate the capacity of the existing storm drain system along Kennewick Place NE and NE 27' Street, a King County BWPIPE hydraulic model was developed in accordance with KCSWDM methodologies. The BWPIPE model is a direct-step backwater program that can be used to evaluated capacities of pipe systems. The BWPIPE program computes backwater profiles through the system for a range of flows, considering inlet, outlet, and system losses. The BWPIPE program assumes the pipe system is clean and functioning properly. This system was field inventoried and surveyed as part of this project as described in Section 2. The pipe system modeled is illustrated on Figure 2. Elevation and pipe configuration data for pipe reaches 1 through 9 were based upon the field inventory as described in Section 2. Elevation and pipe configuration data for pipe reaches 10 through 14 were based upon the system's design drawings (using a 3.58 elevation datum adjustment to get to the current City datum). The capacity of the existing system is summarized in Table 5. The analysis of the existing pipe system indicates that it has adequate conveyance capacity for the peak flow under both the 100-year existing and future land use storm events in Basin D.
