This report focuses on the overall condition of the regional ' drainage system relative to the proposed Park Avenue Improvements Project. The re- gional drainage system is defined as the storm drains conveying runoff from the North Renton drainage basin to Lake Washington. The information presented below is drawn ' from analyses of the Park Avenue North, Garden Avenue North, and Houser Way North drainage systems; these analyses are described in Appendix A. ' DRAINAGE SYSTEM OVERVIEW 1 The North Renton drainage basin consists of approximately 980 acres of developed upland area east of 1-405 (see figure 2) which drains onto 250 acres of flat valley floor west of 1-405. The main storm drain on the valley floor runs west beneath North 8th ' Street from Houser Way North to Garden Avenue North, and then north along Garden Avenue North (figure 3). At the north end of Garden Avenue North, in the vicinity of ' Gene Coulon Memorial Beach Park, the water outlets into the first of a series of five open channels which are connected by culverts. These channels are referred to as the lower ponds. The first and second ponds are on either side of Lake Washington Boulevard, ' the third and fourth are along the northern edge of the Puget Power property, and the last pond is located in Gene Coulon Memorial Beach Park. All drainage from the North Renton basin flows through these ponds into Lake Washington. The regional drainage system consists of all pipes conveying flow from the North Renton drainage basin to Lake Washington. The valley system consists of the pipes on ' the valley floor. The Park Avenue North and Garden Avenue North systems consist of the pipes carrying runoff on those streets, north of North 8th Street. ' There are two points at which the Park Avenue North storm system interacts with the rest of the regional drainage system. Flow from the northern section of the Park Avenue North project and from the first pond, which receives runoff from the rest of the North ' Renton basin, outfalls into the second pond. There is also a cross-connection along North 8th Street which could introduce small flows into the Park Avenue North system from the Garden Avenue North system, but its effects on the regional system would be minimal. The southern part of the Park Avenue North.,lmprovements Proje t drains to the Cedar River, and does not affect the regional drainage system, so it is'lot consid- ered in this report. On-site drainage issues for Park Avenue North have been addressed ' in the design report (Entranco 1992a).

All of the areas draining to the pond system were determined, and di- vided into 17 contributing drainage basins using topographical maps and diagrams of the drainage systems provided by the City of Renton (figure 4). A large section of the Park ' Avenue Improvements Project is represented as basins 12 and 13. Basin 13 drains to the Cedar River, and any impact it would have on the regional drainage system would be minimal. Many of the basins have been divided into subbasins when finer detail was re- quired for a particular study. These subdivided basins include basins 10, 11, 13, 14, 18, and 19. The modeled characteristics of all of the basins and subbasins are shown in Appendix B. Times of concentration for the basins were found using the methodology described in the 1990 King County Surface Water Design Manual (KCSWDM). The longest flow ' routes were determined using topographic maps and storm drain maps provided by the City of Renton. The time of concentration used for a basin was not changed throughout the studies, except for that of the PACCAR site (basin 14) in which the time of concen- tration was changed as site development progressed. See Appendix B. United States Department of Agriculture Soil Conservation Service (SCS) curve ' numbers for pervious land within each subbasin were determined from SCS soil maps (USDA SCS 1973). The amount of impervious surface within each basin was estimated ' on the basis of land use. Land use was determined from aerial photos and field obser- vations. The amount of effective impervious surface within each land use was based upon the following percentages (USGS 1990): Percent Impervious ' Land Use Surface ' Residential 10-35 Multi-family 60 Commercial/Industrial 90 The hydrographs used in the final analyses were generated using the Santa Barbara ' Urban Hydrograph (SBUH) method as defined in the KCSWDM. The rainfalls for the design storms of 2-, 10-, 25-, and 100-year return frequency were taken from the KCSWDM and were 2.0, 2.9, 3.4, and 3.9 inches over a 24-hour period, respectively. ' Runoff from the hillside east of 1-405 creates large flows which are then trapsmitted to the pipe systems on the valley floor, and eventually through the ponds (table 1).

These include the development on the PACCAR ' site and the proposed road improvements along Park Avenue North, Houser Way North, and Lake Washington Boulevard. The increased impervious area will result in an in- crease in the volume of runoff generated in this area, and possibly an increase in the ' peak flows. When detention is provided for these projects, the peak flows can be re- duced, but the volume of stormwater generated will still increase. HYDRAULICS ' Detailed hydraulic analyses were conducted for the valley floor system. The drain- age system on the valley floor is split into three major sections: the Gar-den,Avenue ' North, Houser Way North, and lower pond systems. The Garden Avenue forth/North 8th Street systems make up the major storm drains in the area and conve�Ithe majority of flow, both from the upland area and the valley floor. The system along Houser Way ' North also carries flows from both the uplands and the valley. These both outfall into the ' 91024-20 Regional Drainage Study(10/13/92)caw 7 ' lower pond system, which is in Gene Coulon Memorial Beach Park, and which eventually receives all of the flow from the drainage basin, and flows into Lake Washington (figure ' 3). ' Garden Avenue North/North 8th Street System The storm drains along North 8th Street and Garden Avenue North comprise the ' most significant pipe systems on the valley floor. Along North 8th Street, a 42-inch di- ameter storm drain conveys runoff from the intersection with Houser Way North to the intersection with Garden Avenue North. The existing Garden Avenue North storm drain begins as a 48-inch diameter pipe and transitions into a 54-inch diameter pipe a short distance north of the North 8th Street/Garden Avenue North intersection. This pipe car- nes flows from North 8th Street and Garden Avenue North to the first pond. The Garden Avenue North system carries much of the flow generated on the hillside. ' Additionally, it carries flows from the PACCAR site and local drainage from the adjacent Boeing properties. More than half of the flow entering the pond system is from the Garden Avenue North system, which under existing conditions is limited by the ' backwater effects caused by water levels in the pond system. A new 72-inch diameter line is being added to the Garden Avenue North system as part of the PACCAR development. Once installed, it will nearly double the capacity of the Garden Avenue ' North system. It is scheduled for completion late in 1992. ' Houser Way North System The second major section of the valley floor drainage system is the pipe system along the portion of Houser Way North south of SR 900. It consists of 18-inch to 24-inch diameter pipes which convey the stormwater from the roadway and runoff from 1-405 and the hillside to the pond system. The flows through this system are relatively small com- pared to the Garden Avenue North line, but this system has been shown to flood in the area of the SR 900 overpass. ' Lower Pond System ' The lower ponds are actually a series of open channels connected by culverts. The first pond is located between Park Avenue North and Lake Washington Boulevard. It re- ceives flows from three pipe systems: Garden Avenue North, Houser Way North and the North Basin system, which conveys the flows from Basins 2, 3, and 4 on the hillside (figure 4). There are two 48-inch diameter culverts under Lake Washington Boulevard ' which connect this pond to the second pond. The second pond is between Lake Washington Boulevard and the Burlington Northern Railroad tracks, and is tie outfall for the Park Avenue North drainage system. Two 48-inch culverts lead from this pond to the ' third pond. The third and fourth ponds run along the eastern edge of the Puget Power ' 91024.20 Regionai Drainage Study(10110,921 csw 8 ' property and are connected b three 60-inch CMP culverts. One of the culverts i cur- rently P Y Y s cu ' rently blocked by silt and vegetation. The final pond runs through Gene Coulon Memorial Beach Park and into Lake Washington. Again, there are three 60-inch culverts connecting this pond to the previous one, but one is effectively blocked by vegetation. The vegetation within the channels reduces the flow of water through the pond sys- tem, although maintenance will improve those conditions. The analyses conducted for ' these studies assumed that the channels were in a maintained condition, per direction from the City of Renton. However, it should be noted that these ponds need to be maintained in order to provide the design flow capacity. ' As part of the drainage improvements for the PACCAR site, additional culverts have been installed between the first and second, and the second and third ponds. The con- veyance through the ponds was found to be 35 to 41 percent greater after the pond im- provements and the other Garden Avenue North improvements. Analysis ' Initially, the King County BWPIPE program, a steady-state backwater model, was used in an attempt to gain an understanding of the workings of these systems. Data was obtained from the City of Renton's pipe attribute listing, a number of plan sets of the ' area, and survey data conducted for different studies. A set of curves was developed which defined the flow capacities of different segments of these systems given the steady-state conditions. However, it was found that this system is too complex to accu- rately model using the steady-state assumptions, so the dynamic model EXTRAN was used. This model was formulated to find the flows and water levels in every part of the ' system at five-second time steps over a 24-hour period. A schematic of the model, the major assumptions of the model, and a sample input file are shown in Appendix D. ' The EXTRAN model was updated and improved a number of times and was used to analyze several different options for drainage improvements. The capacities of the ele- ments in the regional drainage system—based on the most recent model improve- ments—are shown in tables 2 and 3. The existing condition indicates the situation at the beginning of the study (table 2), and the future condition assumes the Garden Avenue North improvements (design as of September 24, 1992) are in place (table 3). ' The improvements result in increased flow through the pond system and the Garden Avenue North/North 8th Street lines. Also, conveyance in the rest of the system is not affected. The decrease in peak flow observed at the end of the Park Avenue North line ' is explained below. See figure 5 for pipe locations.

Since the cross-connection between the Garden ' Avenue North system and the Cedar River was found to have such a small capacity, the system draining to the Cedar River will probably not be impacted greatly by any of these proposed changes. One exception would be if the improvements involve removing the cross-connection, although this probably would not greatly increase flows or flooding in the Park Avenue North system. The part of the Park Avenue North system lmost vulnerable to impact is the northern part of the project, which drains to the pond/channel ' system and through Gene Coulon Memorial Beach Park.

The effect on the Park Avenue North system would be dictated by the level of water in the second pond, where the outfall for that system is lo- cated. The pond improvements would tend to decrease the water level, improving the drainage off of Park Avenue North, while the addition of the 72-inch pipe would increase the amount of flow delivered to the ponds and may have the reverse effect, i.e., pond levels would tend to rise. ' 91024-20 Regional Drainage Study(1011 3192)mw 1 1 The EXTRAN model indicated that there would be a period of time during the height of the storm events in which the improvements would cause higher tailwater conditions ' for the Park Avenue North system outfall. This could reduce the flow of water through the system. However, increased water levels in the Park Avenue North pipe system ' were observed only in the two pipes closest to the outfall for a duration of less than two hours for the 25-year design storm. Flows in the rest of the Park Avenue North system were not affected, as shown in tables 2 and 3. tThe peak water levels at the outfall (table 4) increase slightly due to the improve- ments being provided as a part of the PACCAR development. But increased water lev- els occur only for a short period; over the duration of the storm, water levels in Pond 2 tend to be slightly lower. These levels do not lead to flooding in the Park Avenue North system. The backwater analysis conducted for the Park Avenue Improvements Project ' indicated that the Park Avenue North system would be unaffected by backwater if the water level at the outlet was less than or equal to 21.1 feet, so the backwater should have no effect on the conveyance from the system for storms smaller than the 100-year event. ' Table 4 Existing and Future Peak Water Elevations 1 at Park Avenue North Outfall (feet) iDesign Storm Existing Future ' 2-year 19.2 19.5 10-year 20.3 20.4 25-year 20.6 20.8 ' 100-year 20.8 21.0 ' The Park Avenue Improvements Project is unlikely to have a significant regional im- pact on the drainage system as currently designed, as the increased volumes generated by the Park Avenue Improvements Project are relatively small compared to the total ' runoff conveyed through the pond system. Specifics regarding the on-site drainage from the Park Avenue Improvements Project are not included here, but can tie found in the 1 Final Design Studies (Entranco 1992a). 'A At the time of development of the Park Avenue Design Studies, the plans to improve the Garden Avenue North drainage system involved intersecting the 48-inch pipe at the ' 91024-20 Regional Drainage Study(10/13192)Gsw 13 1 Park Avenue North outlet with a new 72-inch pipe. This pipe would have conveyed water under the Burlington Northern Railroad tracks to the pond system further downstream. A ' biofiltration swale was proposed in the Park Avenue Improvements Project design stud- ies to be built in conjunction with that design. However, since the design for the 72-inch ' pipe has changed so that it would outlet in the first pond, the concept for providing biofil- tration in the proposed area will have to be altered accordingly. The revised biofiltration concept would also have to consider the roadway alignment for the Park Avenue North/Lake Washington Boulevard Project as designed by Tudor Engineering. Additionally, the improvements to the ponds would probably eliminate the option of ' designing a sedimentation pond in the pond/channel system. Sedimentation ponds are designed to remove particles from the water, primarily by slowing the water and allowing the particles to fall out. Since the purpose of the pond improvements is to increase the conveyance through the ponds, installing a sedimentation facility would be counter-pro- ductive. Despite the design changes which would be necessary due to the conflicts described above, it may still be possible to construct a biofiltration facility for the stormwater from the Park Avenue North project area. However, space is a major constraint and it is not ' known whether there is adequate room for such a facility. The alternative for water qual- ity enhancement would be to construct a wet vault as described in the Final Design ' Studies (Entranco 1992a). ' SUMMARY A series of modeling efforts have been undertaken to characterize the drainage sys- tems around Garden Avenue North, Houser Way North, and Park Avenue North in Renton, Washington. The regional drainage system was found to be too complex to adequately model with steady-state models, so a model using the EXTRAN module of 1 the US EPA's Storm Water Management Model was developed and refined. The pro- posed improvements to the regional system were not found to have a significant impact on the drainage from the proposed Park Avenue Improvements Project as currently de- signed. However, the water surface elevations in table 4 determined in this study should be used to verify any effects on the final design. ' REFERENCES ' Entranco 1991 Garden Avenue Drainage Study.

The steady-state analyses indicated that even design flows as low as the two-year return rate were capable of causing wide-scale flooding on the valley floor, due to high flows from the hillside and backwater effects from water levels in the first pond. Also, the pipe system on the PACCAR site was found to be inadequate to convey the two-year peak flows from the basin (Basin 15) draining to the PACCAR system. An 18- inch restrictor pipe in the PACCAR pipe system caused flooding on the site; the pipe was found to have a maximum flow of only 7 cfs under optimal flow conditions, and the peak flow through it for the 2-year storm was estimated to be 12.9 cfs. ' The same backwater analysis was performed for the system with the cross- connection at North 8th Street, outfalling to the Cedar River. The flow from the Garden ' Avenue North system to the Cedar River was found to be small. Depending on the tailwater conditions, the amount of flow entering this system via the cross-connection would be limited to a maximum of 4 to 6 cfs. A set of operational curves was produced for seven sections of the regional stormwater system. These curves define the expected flow given various headwater and 1 tailwater conditions. The curves and a map of the modeled sections are included at the end of this appendix. However, the system was found to be too complex to be modeled adequately using steady-state assumptions; these assumptions would tend to ' overestimate the amount of flooding which would occur under storm conditions. It was suggested that another model, such as the EXTRAN block of the Storm Water Management Model (SWMM), be used to obtain a more accurate understanding of the ' dynamics of the system. ' GARDEN AVENUE ADDENDUM #1 A second study was conducted to determine what drainage alternatives were available for the PACCAR development. The study examined several potential alternatives, including enlarging the culverts for the pond/channel system, bypassing ' stormflow down Houser Way North, and enlarging the existing Garden Avenue North storm drain. Results of a steady-state backwater analysis demonstrated that a combination of increased capacity in both the pond/channel system and the-valley storm 1 drain system would reduce flooding on the valley floor. Improving the valley floor pipe system without improving the pond conveyance was shown to result in better drainage in ' 91024-20 Regional Orainage Study(10/12/92)mw A.1 the Garden Street North area, but with considerable flooding in the pond system. ' Conversely, the effect of increasing the size of the pond system culverts would be negated somewhat unless the capacity of the Garden Avenue North line were increased. ' GARDEN AVENUE ADDENDUM #2 ' After the second part of the Garden Avenue study was completed, ENTRANCO began to analyze the valley floor drainage using the EXTRAN module of the SWMM. The EXTRAN model offers a more detailed analysis of the valley floor drainage, allowing ' the dynamic routing of full hydrographs through the storm drain system. The difference between EXTRAN modeling and the previously used steady-state modeling is that the EXTRAN model allows conditions to be tracked throughout the duration of a storm, Iwhereas the steady-state analysis permits only a snapshot of conditions at one flow rate and assumes that that flow rate is maintained for an indefinite period of time. The EXTRAN model developed for the study represented over 115 pipes and 120 structures for the principal drainage system on the valley floor. Information used to ' define the system was obtained from a combination of sources including field survey, existing plan sets, and the City of Renton database. A schematic of the modeled representation of the system is included in Appendix C of this report, along with a model input file. The model was run to represent 24-hour storms, and the hydrographs entering the system were developed as explained in the Hydrology section of the main body of this report. 1 The predicted volume of flooding throughout the system for the 25-year storm event was approximately 16 acre-feet, of which sixty percent was located on the undeveloped ' PACCAR site. Flooding on the PACCAR site served to promote flooding on adjacent properties. Flood waters built up on the northwest corner of the property, and this water spilled over onto adjacent the low-lying areas along Garden Avenue North, west of the PACCAR site. The runoff that ponded on the PACCAR site came from three sources: rainfall onto the site, flooding due to inadequate conveyance in the storm drain line ' through the property, and discharge from the North 8th Street line. On the pre-developed PACCAR site, a drainage ditch conveyed stormwater to the 1 northwest corner of the site. The outlet of this ditch was a 24-inch diameter pipe which flowed into the North 8th Street storm line. When the North 8th Street storm drain began to surcharge as a result of high flows from the upland areas, water flowed back onto the PACCAR site through the ditch outlet. During the simulation of the 25-year storm event, approximately 4.3 acre-feet of runoff was diverted onto the PACCAR site through the ditch outlet. Discharge onto the site averaged 5.5 cfs over a 9.5 hour period, with a maximum discharge of 17 cfs. The January 9, 1990 storm event was modeled, and the results were compared with ' field observations. According to the EXTRAN model, approximately 3.5 acre-feet of 91024-20 Regional Drainage Study(10/12,92)csw A.2 runoff entered the site through the ditch outlet. The maximum water surface elevation modeled for this storm was approximately 27.5 feet, which is reasonably close to the 'V levels that were observed on the site. The EXTRAN model was used to evaluate potential drainage alternatives for the PACCAR development. This addendum evaluated the need for pumping stormwater offsite, as well as bypass alternatives for some of the flows currently conveyed by the North 8th Street and Garden Avenue North pipe systems. Among the assumptions for this analysis was improvement of the conveyance ' capacity of the pond system. The assumed pond improvements included enlarged culverts beneath both Lake Washington Boulevard and the Burlington Northern Railroad tracks, with the existing 48-inch diameter culverts (two at each location) replaced by tthree 60-inch culverts at each location. The PACCAR site was assumed to be filled to 29 feet of elevation, with the southern half of the site draining, preferably via gravity, to the ' Garden Avenue North system, and the northern half draining to an onsite detention pond. Pumping would be necessary to introduce water from the detention pond to the Garden Avenue North system. ' The pipe system through the PACCAR site was replaced by a 36-inch bypass pipe. This pipe was designed to convey the flows from basin 15 without flooding the site, and connects to the existing storm drain at the intersection of North 8th Street and Garden Avenue North. ' This study looked at the feasibility of bypassing flows from North 8th Street, which currently flow into the Garden Avenue North system, down Houser Way North to allow some capacity in the Garden Avenue North line for use by the PACCAR development. However, model runs indicated that the installation of a Houser Way North bypass would not eliminate the necessity of pumping, nor would it significantly reduce the maximum water levels at the PACCAR outf all. Also, it was found that gravity drainage would not be ' possible for the southern half of the site, necessitating additional pumping. Cross- connections with the North 8th Street system would be removed, so flooding from that ' storm system onto the PACCAR site would be reduced, but the amount of flooding at North 8th Street and Houser Way North would be increased, from 3.8 to 7.5 acre-feet for the 25-year design storm. The pumping and bypass solutions were later abandoned in ' light of new information that allowed a more viable solution, i.e., expanding the conveyance down Garden Avenue North. It is important to note that.@_Il model runs evaluating improvement alternatives throughout all the studies assumed that the pond system channels were cleaned and maintained. Field inspections have shown that in many places there currently are ' bushes and other vegetation which reduce the flow capacity of the system. Per the City of Renton, it was assumed that, in the future, the necessary maintenance4ill occur to ensure unrestricted flow. 1 91024-20 Regional Drainage Study(10112/92)a w A.3 GARDEN AVENUE ADDENDUM #3 ' Addendum No. 3 described the results of EXTRAN model runs to evaluate the impacts of placing a 72-inch line along Garden Avenue North, paralleling the existing ' system and connecting with the North 8th Street storm drain. This line was partially installed as part of past improvements. The results of the EXTRAN modeling indicated that this alternative would significantly increase the capacity of the overall drainage system and would allow PACCAR to discharge stormwater from its developed site via gravity drainage. It would also reduce ' overall flooding relative to the existing conditions. Additionally, the flooding on the PACCAR site and the flooding from runoff onto adjacent properties would be alleviated. Lower water levels along the existing Garden Avenue North storm drain and at the outlet from the PACCAR site were predicted. The flow through the ponds was shown to increase by about 25 percent. However, this design considered the 72-inch pipe to ' outlet into the third pond, and in the final design, this pipe outlets into the first pond. Later runs indicate that discharging to the first pond does not change the conclusions ' regarding this improvement alternative. HOUSER WAY REGIONAL DRAINAGE ANALYSIS The EXTRAN model developed for the Garden Avenue studies was further refined for ' the Houser Way Regional Drainage Analysis. The purpose of this study was to analyze the existing conditions in the vicinity of the Houser Way Relocation Improvements project, and then to evaluate several alternatives to improve the regional runoff conveyance through that area. Model improvements included increasing the detail of the represented drainage along ' Houser Way North. Information was gathered from plan sets supplied by the City of Renton and field investigations. Basins 10 and 19 were broken into sub-basins to more precisely model the flows around the Houser Way North systems. Some hydrographs ' which had been combined earlier to represent a group of basins were split into individual basin hydrographs. The modeled storm drainage systems were extended to capture ' flows from these individual basins on the hillside to the north and the east of the site. The net result of these model improvements is to more accurately represent the function of the systems in the immediate vicinity of Houser Way North. ' A critical assumption was developed to deal with flooding on the hillside. Flooding is predicted at the uppermost point of the pipe from the hillside to the North 8th Street ' storm sewer. That point is called junction 1207 in this version of the model (see Appendix C). Due to the formulation of the EXTRAN model, the water which floods does not return to the system, and is lost. Since the flooding was observed to be ' significant (over 12 acre-feet for the 25-year storm), an alternate pathway for this water 91024-20 Regional Drainage Study(10/12192)=w A.4 was modeled. Based on topographic information and previous studies (City of Renton 1988), it was assumed that this water would appear as street flooding until reaching a swale along 1-405, where it would proceed to flow under 1-405 and into the vacated Houser Way North right-of-way. Although this assumption is based on precedent, and results in a more reasonable simulation than if the loss of stormwater volume were ignored, it is not certain that this is ' the path taken by the floodwater's, and it is unlikely that all of the predicted flooding would occur at this point. The pipe systems further up in the basin were modeled in an effort to check their operation, and these pipes were found to be overloaded and flooding, thus decreasing the flow reaching junction 1207. This indicates that there is some attenuation of high flows within the pipe system in the east basins, and that the actual flows to junction 1207 are lower than the modeled flows. The hydrograph method used is unable to account for attenuation in the pipe system; therefore, modeled results can be assumed to represent a worst-case scenario. The proposed improvements to the Garden Avenue North system were assumed to have occurred. The improvements include both the completion of the 72-inch storm ' drain down Garden Avenue North and increasing the size of the culverts between the ponds. The conveyance between the first two ponds was assumed to be increased by the addition of two 54-inch culverts, and one 84-inch culvert was assumed to be added to the culverts between the second and third ponds. The analysis of this system indicated that under the modeled conditions, the North ' 8th Street line would reach maximum flow during rainfall events approximately the size of the 10-year, 24-hour storm. Instead of passing larger flows, this pipe would serve to create a restriction on the pipes entering the valley floor system at the intersection of ' North 8th Street and Houser Way North, and introduce a backwater situation upstream. The pond system, on the other hand, does not appear to reach its maximum conveyance even during the large flow events. However, the increasing levels in the ponds did begin to show backwater effects on the pipes entering the pond system. ' Street flooding seemed to be relatively unchanged by increasing the size of the culverts in the pond system relative to the preimproved model runs. The flooding at the Houser Way North underpass was estimated at 0.1, 0.7, 1.4, and 2.5 acre-feet for the 2-, 10-, 25-, and 100-year design storms, respectively. No flooding was predicted along Garden Avenue North; however, the backwater conditions caused by the North 8th Street pipe do lead to flooding at North 8th Street and Houser Way North. As noted before, one of the critical assumptions for this modeling was the routing of overflow waters from the area on the hillside to the channel in the Houser Way North right-of-way. It is primarily this flow which seems to result in the flooding in the vicinity of the intersection. Again, it is not certain how much of this flow is actually attenuated in the systems on the hillside. Any attenuation would probably lead to lower predicted flooding on the valley floor. ' 91024-20 Regional Drainage Sluoy(1011 Z'92)c w A.5 ' It was assumed that the primary impact that Houser Way North improvements p ry p y p is would ' have on the regional stormwater system would be to replace the existing open channel with a large-diameter pipe. All three alternatives considered to improve the Houser Way North drainage system involve replacing the channel with a 72-inch pipe. One ' alternative was to replace the 42-inch North 8th Street pipe with a 72-inch pipe. The second alternative also upgraded the North 8th Street pipe to 72-inch and removed a cross-connection between the.72-inch Garden Avenue North pipe system and the ' smaller Garden Avenue North pipe system. The third alternative was to build a 10-foot wide swale and overflow pipe along Houser Way North north of North 8th Street to divert flow from the North 8th Street line and pick up drainage from the hillside. ' Replacement of the channel with a large pipe was found to not affect the operation of the regional drainage system. The existing flooding continues, as well as the existing flows, so the replacement cannot be considered to be a drainage improvement. Of the three alternatives, the second appears to be superior to the first, as the removal of the cross-connection seems to improve drainage in the Garden Avenue North lines. In both ' of the first two alternatives, flooding is reduced but the water levels in the North 8th Street line are increased, which affects the drainage from the PACCAR site. The third alternative does not reduce flooding as much as the other two, but it provides biofiltration and does not affect the drainage from the PACCAR site. Further unpublished investigation in this area evaluated an additional alternative for drainage improvements. There is a site on the hillside, in Basin 9, which appears to provide an opportunity for detention. Storm flows from several pipe systems on the ' hillside could be diverted to a pond constructed on this site, and model runs incorporating such detention have shown that the operation of the regional drainage system may be improved. Also, the size of the pipe necessary to replace the channel ' along Houser Way North could be downsized if such detention were in place. ' GARDEN AVENUE ADDENDUM #4 Addendum No. 4 verified the proposed Garden Avenue North improvements using the refined model formulation as devised for the Houser Way Regional Drainage Analysis. The improvements included installing the additional culverts in the pond ' system as described above and completing the 72-inch line along Garden Avenue North. Modifications of the model included use of the final design elevations and specifications in the model formulation. ' The proposed improvements were estimated to increase the conveyance of the pond system by approximately 35 percent. Predicted flooding would decrease relative to the ' conditions previous to the PACCAR development. The risk of erosion in the three downstream ponds would not increase. ' 91024-20 Regional Drainage Study(1 011 2/9 21 csw A.6 ' Due to higher water levels in the ponds, a small backwater effect was found on the outfall for the Park Avenue North system during part of the storm. However, this was ' observed to be localized at the downstream end of the system and to be of short duration. The conveyance of stormwater from Park Avenue North was unaffected, and ' the maximum water levels within the system decreased slightly. Problems arising in the construction of the drainage improvements along Garden Avenue North forced a modification of the design of those improvements. The changes ' included moving the location of a cross-connection between the two Garden Avenue North pipes and downsizing the connection between the 72-inch pipe and the North 8th ' Street line. When the connection between the 72-inch Garden Avenue North pipe and the North 8th Street pipe was 48 inches, these modifications were found to mimic the original design of the system. The design flows and water levels for the revised system, along with those for the most recent version of the model of the system (circa 1991), are presented in the main body of the report.

The source code for the model as well as a schematic of the junctions follow this section. The hydrograph cards appended onto the model are not included, but they are available upon request. The hydrology for the model runs was determined by Entranco for the original Garden Avenue Drainage Study report from maps, aerial photographs, and field investigation. Subsequent investigation resulted in minor changes which were incorporated into the model. Hydrographs were created with the Santa Barbara Urban ' Hydrograph method, using the King County 24-hour hydrograph. The actual hydrograph generation was performed either on the King County HYD program or by using WaterWorks. In the case of basins which had more than one inlet to the stormwater system, the hydrograph flows were split into equal portions and placed in the appropriate junctions. There are 51 individual inlet points in the system, and 30 of those inlets result from splitting 5 larger hydrographs. ' The attached model code is for the post-developed condition with the proposed improvements. Among the features which differ in the pre-developed condition are the ' pipe system and condition of the PACCAR site, which was modeled to include a series of storage areas for flood waters, the lack of a 72-inch pipe from junction 1605 to 1612 and ' smaller culverts between Ponds 1 (1001), 2 (2001) and 3 (3001). One of the critical assumptions regarding the lower pond system is that the channels are well maintained to allow maximum flow. Currently, the ponds are not in a condition to allow such flow. ' The level of Lake Washington is assumed to be at 15 feet above mean sea level. This tends to be a conservative estimate because the U.S. Army Corps of Engineers regulates the lake water level, and in the winter, when the modeled storm events are likely to occur, the lake is closer to an elevation of 13 feet. However, backwater analyses using the King County BWPIPE model indicated a change in lake level between 12 and 17 feet of elevation has no effect on the conveyance through the pond system. The EXTRAN model was prone to instabilities. An instability results in extreme fluctuations in water levels and/or flows at a given point in the system over a short period ' of time, which often affects several pipes and junctions in the area of the instability. These are a result of the equations in the model and do not necessarily have physical significance, although they generally occurred at times when there was a large increase ' in the amount of flow through an area. Several methods were used to deal with ' 91024-20 Regional Drainage Study(10,12/92)caw C.1 instability problems. The most common method used in this model was replacing a relatively short pipe with an equivalent pipe of longer length. This was done by decreasing the Manning's "n" of the longer pipe so that the flow through the pipe was similar. Occasionally, a long pipe was also shortened by using the same method. The ' pipes in this system were modeled as being between 100 and 500 feet long. Another method was representing a pipe between two manholes as an orifice. It was found that instabilities tended to occur in some manholes having two pipes which flow out of that manhole. In cases where this happened, the higher pipe was replaced with an orifice in ' the model formulation. Finally, some open channels in the system experienced instability. The operation was sometimes improved by representing the channels as ' large storage junctions. The first pond, junction 1000, is one example of this occurrence. The EXTRAN model does not take entrance losses, exit losses and minor losses due ' to bends into account. In order to accurately model the system, the Manning's "n"s in the pipes must be increased to mimic the losses. To find the appropriate changes in the Manning's "n", runs through the system were compared to runs of the BWPIPE model, ' which does account for these losses. It was found that an increase of "n" to 0.017 for concrete pipes and 0.030 for corrugated metal pipes produced the same flow/headwater relationships as the runs accounting for entrance and exit losses. An additional 0.005 ' increase mimicked a 90-degree bend. Therefore, in the model formulation, these adjusted Manning's "n"s were used. SThe final set of assumptions dealt with flooding issues. The EXTRAN model monitors the amount of water which overflows out of a manhole and reports it as flooding, but the ' water does not reenter the stormwater system and is lost. In order to mimic the effects of street flooding, much of which would end up reentering the system at another point or later in the storm, storage junctions and channels were used to represent the area which would flood. The top elevations of the manholes which contribute to the flooding are raised enough to place an orifice between the flooding manhole and the storage junction/channel. In this way, the water is not lost, and the actual amount of flooding at any given time can be determined using the height of water in the storage junction. The issue of flooding on the hillside is related to this. The highest manhole represented on the hillside, junction 1207, displayed flooding at high flows. The flooding was assumed to enter the street and then a nearby swale to be conveyed to another ' point in the system. This agrees with an earlier report by the City of Renton, but the amount of flow which actually follows this route is suspect. It is likely that attenuation occurs in the system further up the hill, resulting in less flood flow. However, with this formulation of the model it was not possible to determine the amount of attenuation, and therefore the amount of water which is shown to flood is the maximum possible flooding. .f '

SWP272265.doc CITY OF RENTON MEMORANDUM DATE: February 23, 1993 TO: Joe Armstrong FROM: Dave Jennings . SUBJECT: ENTRANCO REGIONAL DRAINAGE ANALYSIS - HOUSER WAY PROJECT Thank you for the opportunity to review Entranco's final drainage for the Houser Way Project. I reviewed the report for the comments submitted in my September 10, 1992 memo to you. In general, I thought the report's presentation and content were much improved. I especially think the information or the relative capacities of maintained vs. unmaintained swales through Coulon Park (15% decrease in upstream capacity; 0.8' increase in flood depth when unmaintained) for the 25-year storm event is important and useful. However, some information was not provided as requested. The pertinent comments from my previous memo are repeated below (referring to Entranco's June 4, 1992 submittal): Page 3, table 1: Show additional column(s) for critical water level (depth, feet) and maximum expected flows (cfs) beyond which flooding will occur. Page 4, paragraph 1: What is the maximum flow capacity (in cfs) for each of the pond segments under both "no vegetation" and "existing" (vegetated) conditions? Page 4, paragraph 2: Flood volumes are noted at the Houser Way Underpass for critical storm events. What critical flow value (cfs) must be exceeded before flooding will occur at this location? Provide similar information for the Garden Avenue and North 8th Street locations. Page 6, table 2: Provide critical flow rate capacities (cfs) in the table for which no flooding will occur. Add column(s) showing the amount(s) of flow by which capacity will be exceeded (system floods at 10-year, 24 hour storm ±). Joe Armstrong Entranco Regional Drainage Analysis - Houser Way Project Page 2 SUMMARY: The information on existing flow capacity is critical because it allows direct comparison of nominal capacity with modeled flows. This would provide an indication of how much additional capacity is required to provide an acceptable level-of-service. This information is critical to understanding the limitations in the entire drainage system. In addition, the following points were raised in this review: • Was HSPF used in any part of this analysis? (See Page 7.) Why was HSPF used to model flows? What flow monitoring data was available to provide calibration data? No information on how an HSPF model was developed or applied was provided in the report. • Summary model input and output should be provided in a technical appendix. Model inflows/discharges in each pipe segment vs. pipe capacity should be noted. If any field survey was performed to verify pipe sizes, and/or rim and invert elevations, this data should be provided with the final report. Any input files used with the model should also be provided on floppy disk with appropriate summary documentation. Please provide the Surface Water Utility with at least one (1) copy of the final submittal. Call me at X-6205 if you have any further questions or concerns.

The project area runs parallel to 1-405 between Sunset Boulevard and Lake Washington Boulevard in Renton, Washington (figure 1). Planned improvements will extend Houser Way through currently vacated right-of-way from North 8th Street south to Sunset Boule- vard, resulting in loss of existing wetland and an open channel. Runoff from developed upland areas is conveyed through the Houser Way area on the valley floor, by way of the open channel or through one of a number of pipes along the hillside, and is eventu- ally discharged to Lake Washington. An existing EXTRAN storm sewer model (a mod- ule of the EPA SWMM model) of the region was refined to provide increased resolution of the project area, and the refined model was used to analyze how the stormwater is conveyed through the existing system. Using the results of the model runs, several op- tions to mitigate the expected changes in the system due to the Houser Way project were evaluated and costs determined for the various alternatives. It is important to note that this analysis focuses on the Houser Way project as it impacts regional drainage patterns. Project impacts on site drainage, such as in- creased runoff and need for detention, are beyond the scope of this report and would require further analyses. MODELING The hydrology of this basin had been characterized as a part of earlier studies (Entranco, 1991). For the Houser Way analysis, two changes were made in the hy- drological calculations in order to gain further refinement for this analysis. First, the drainage basins around Houser Way were further subdivided into several subbasins and the flows for the design storms were calculated for these subbasins. Hydrographs for all basins were found using the King County method, as delineated in the King County Surface Water Design Manual (1990), using 2, 10, 25 and 100-year 24-hour rain- falls of 2.0, 2.9, 3.4 and 3.9 inches, respectively. The second refinement was to com- bine fewer of the basin hydrographs than had been combined before. Instead, the con- veyance systems were extended to capture flows from individual basins on the hillside to the north and east of the site. The net result of these model improvements is to more accurately mimic the functioning of the systems in the immediate vicinity of Hous- er Way. In previous studies this EXTRAN model had been used to evaluate this area and had been able to reasonably mimic the observations made during the January 9, 1990 storm, a recent storm event with a recurrence interval of around 25 years. The model 91024-22 Regional Drainage Analysis(64i92)aem 1 3 formulation was improved by the inclusion of information from recent sur,/eys conduct- ed by Tudor Engineering and SSOE. This information, along with site observations, al- lowed a more detailed model of the existing Houser Way area to be developed. Two assumptions were made concerning the condition of the lower section of the drainage system. At the direction of the City of Renton, the open channels which start south of Lake Washington Boulevard and travel through Gene Coulon Memorial Beach Park, hereafter referred to as the pond system, are assumed to be well maintained and free of overgrown bushes. This results in a lower resistance to flow than would occur if the ponds were not maintained. Additionally, the culverts connecting the ponds were assumed to be expanded as planned by the PACCAR project. The added culverts in- clude two 54-inch pipes from the southernmost channel (Pond 1) to the next (Pond 2), and one 84-inch pipe from Pond 2 to Pond 3. These two assumptions are critical to the modeling results, as they increase the conveyance in the pond system which, in turn, increases the conveyance of the entire stormwater system. Predicted flooding leads to another critical assumption regarding the model re- sults. At the uppermost point of the pipe which connects to the North 8th Street storm sewer line from the east, flooding is predicted to occur during high flows. In this ver- sion of the model, this point is called junction 1207 (see figure 2). Due to the formula- tion of the EXTRAN model, the water which floods does not return to the system and is lost. Since the flooding was observed to be significant (over 12 acre-feet for the 25- year storm), an alternate pathway for this water was modeled. Based on topographic information and previous studies (City of Renton, 1988), it was assumed that this water would appear as street flooding until it reached a swale along 1-405, eventually dis- charging into the channel along the Houser Way alignment approximately one-third of a mile south of North 8th Street. Although this assumption is based on precedent and results in a more reasonable simulation than had the loss of stormwater volume been ignored, it must be verified be- fore the final design of any system along Houser Way. It is not certain that this is the path taken by the floodwaters, and it is unlikely that all of the predicted flooding would occur at this point. The pipe systems further up into the basin were modeled in an ef- fort to check the functioning of the pipe system, and these pipes were found to be over- loaded and flooded, decreasing the flow to junction 1207. This may indicate that there is some attenuation of high flows within the pipe system in the east basins, and that the actual flows to junction 1207 will be somewhat lower than the modeled flows. The hy- drograph method used is unable to take into account such attenuation, but the modeled results can be assumed to represent a worst case scenario. 91024-22 Regional Drainage Analysis(6AW)aern 2 CURRENT CONDITIONS Selected water levels and pipe flows for the existing conditions model runs are shown in table 1. It is important to note that these results are not necessarily compara- ble to observed storm events due to the inclusion of upgrades to the system. In addi- tion to the assumed upgrades to the pond system discussed above, the conveyance through the system is upgraded by the completion of the 72-inch line down Garden Ave- nue. This line greatly increases the flow capacity to the pond system, and the net re- sult of all of the improvements is a lessening of the backwater conditions which have led to street flooding in the past. Table 1 shows the conditions observed for the different modeled storms given the assumed current conditions. The depth of the stormwater in the system, which deter- mines the flooding situation in the area, is shown for two important locations: the PAC- CAR outfall at North 8th and Garden Avenue (junction 1000) and Pond 1 (junction 1001). Additionally, the flows in several important segments of pipe are shown (in cubic feet per second). Table 1 Current Conditions of Houser Way Drainage System Storm Recurrence Interval (Years) 2 10 25 100 Water Level (ft) at: PACCAR Outfall 2.71 3.14 3.33 3.36 Pond 1 3.16 3.96 4.31 4.49 Flow in Pipe (CFS) North 8th Street 76.90 82.70 82.90 82.90 54-inch Garden 24.30 37.80 47.00 49.00 72-inch Garden 87.90 149.90 146.80 155.40 North Basins 49.80 83.10 89.80 90.40 North Houser 13.00 17.90 20.90 25.60 Pong System 204.40 276.70 316.70 343.90 Houser Channel 31.40 124.10 128.80 128.90 The results in table 1 indicate that under the modeled "current" conditions the 8th Street line would reach its maximum flow during rainfall events approximately the size of the 10-year, 24-hour storm. Instead of passing larger flows, this pipe would serve to create a restriction on the pipes entering the system at the intersection of North 8th Street and Houser Way, and introduce a backwater situation upstream. The pond sys- tem, on the other hand, does not appear to reach its maximum conveyance even dur- 91024-21 Regional Drainage analysis(6/4192)aem 3 ing the large flow events. However, the increasing levels in the ponds do begin to show backwater effects on the pipes coming in from Garden Street and the North Basin for the larger storms. The EXTRAN model also shows the amount of water which flows out of the system as flooding. Street flooding seems to be relatively unchanged by upsizing the culverts in the pond system relative to the preimproved model runs. The flooding at the Houser Way underpass is estimated at 0.1, 0.7, 1.4 and 2.5 acre-feet for the four design storms. No flooding is predicted along Garden Avenue, where most of the regional stormwater flows to the pond system. However, the backwater conditions caused by the North 8th Street pipe do lead to a large amount of flooding at North 8th and Houser (1.1, 8.1, 13.9 and 22.7 acre-feet). As noted before, one of the critical assumptions for this modeling was that the overflow waters from the area on the hillside is routed to the channel along Houser Way. It is primarily this flow which seems to result in the flood- ing in the vicinity of the intersection. Again, it is not certain how much of this flow is ac- tually attenuated in the systems on the hillside. Any attenuation would probably lead to lower predicted flooding on the valley floor. In comparison, the 25-year storm for the existing conditions without the larger pond culverts (but with the assumption of maintained ponds) predicted 1.2 acre-feet of flood- ing at the underpass, 11.7 acre-feet at North 8th Street and Houser Way and 2.8 acre- feet on the hillside, although this run produced 10 percent less flow in the system than the improved condition. The lower amount of flow is because this run used a different hydrograph method which takes attenuation into account. FOCUS The directive for this report is to model the existing stormwater system around the Houser Way site and to provide an analysis of possible improvements to stormwater conveyance. The primary focus concerns the changes in regional drainage due to the Houser Way Improvement project. An analysis of the proposed project indicates that on a regional level the effect of the road improvement will be to alter an area along the railroad tracks south of 8th Street, which currently serves as an open channel for storm flows. It is probable that, in order to construct the roadway, this channel will need to be replaced by an underground pipe. The drainage alternatives considered involve con- verting the channel to a pipe and providing some other improvements in the system. 91024-22 Regional Drainage Analysis(W4l92)aem 4 y DRAINAGE REQUIREMENTS The City of Renton drainage requirements are the same as those defined in the King County Surface Water Design Manual. For this study, Core Requirements 1-4 ap- ply. Core Requirement #1 states that runoff "must be discharged at the natural loca- tion". Depending on interpretation, the natural location for discharge from this area could be considered to be at a specific point within the stormwater system, at Pond 1 or at Lake Washington. The intent of this requirement is to ensure that baseflows of streams are not changed by drainage changes, so the flow between pipes within a stormwater system is of lesser concern. Since the entire system from Houser Way to Pond 1 consists of piped storm drains, the natural discharge of this system can be rea- sonably assumed to be considered to be at Pond 1, which is the assumption used for this analysis. Core Requirement #2 calls for an analysis of upstream and downstream areas which would be impacted by the changes to the drainage system. This study would presumably fulfill much of the analysis requirement. The regional analysis does not consider an increase in the amount of runoff gener- ated in the project area, but Core Requirement #3 applies in that the 100-year, 24-hour peak flow after improvement will be constrained to be no more than 0.5 cfs more than the preimproved 100-year flow. Also, some regional biofiltration may be required as part of the improvement project to replace that occurring in the existing channel. The fourth core requirement indicates that new pipe systems are to be designed to convey the 25-year peak flow. The pipes for this study were designed for such a rate, although, as mentioned earlier, those flows will have to be confirmed before final de- sign. OPTIONS AND RESULTS Three alternatives were considered to improve the functioning of the Houser Way drainage system. For all of the runs, the channel along Houser Way is replaced by four 400-foot long sections of 72-inch pipe set at the slope of the existing ground sur- face. This is due to the assumption that the road placement will require filling the chan- nel. One upgrade alternative is to replace the 42-inch pipe under North 8th Street with a 72-inch pipe. A second is similar to this, but also involves removing the cross con- nection between the 54-inch and the 72-inch lines at North 8th Street and Garden Ave- nue. The third alternative is to build a 10-foot wide swale and 48-inch overflow pipe along Houser Way north of 8th Street to divert some of the flows from the North 8th 91024-22 Reg tonal Drainage Analysis(&4/92)aem 5 Street line and pick up drainage from the hillside. A conceptual drawing of this alterna- tive is shown in figure 3. The swale would have the same surface overflow rate as the existing channel for the 2-year flow, giving it comparable biofiltration capacity. The results for these alternatives for the 100-year storm are shown in table 2.

Alternative 2 is the North 8th Street upgrade with removal of the cross-connection at North 8th and Garden Avenue. Alternative 3 is the bypass swale As shown in table 2, replacement of the channel with a large pipe is not expected to affect the drainage system compared to existing conditions. However, the existing flooding also continues, as well as the existing conveyance, so the replacement cannot be considered to be a drainage improvement. The first alternative, increasing the size of the North 8th Street pipe, leads to in- creased conveyance and reduced flooding throughout the system, eliminating the flood- ing at 8th Street and Houser Way with only a minimal (0.08 acre-feet) amount of flood- ing on Garden Avenue. One major drawback for this option is that it leads to greatly in- creased water levels at the intersection of North 8th Street and Garden Avenue Qunc- tion 1000), where drainage from the PACCAR site enters the system. The higher water levels could lead to restricting the flow of water off of that site and result in flooding. In fact, the predicted flooding on the PACCAR site increases from 0.55 acre-feet to 2.0 acre feet due to the enlarged pipe system. 91024-22 Regional Drainage Analysis(64/92)aem 6 The second alternative improves on the first alternative by removing the cross- connection between the two Garden Avenue lines at North 8th Street. The result is in- creased conveyance through the Garden Avenue systems (254 cfs vs. 235 cfs, 204 cfs for existing) and down the North 8th Street line while the water level at the PACCAR out- fall is 1.5 feet lower than in alternative one. This alternative does lead to some flooding (0.5 acre-feet) from the North 8th Street line, and the water level at junction 1000 is still 2.15 feet higher than under the existing conditions. However, the predicted increase in flooding on the PACCAR site is only 0.15 acre-feet. The bypass swale alternative, like the first two alternatives, also reduces the pre- dicted flooding at North 8th and Houser Way, although it does not eliminate that flood- ing. Additionally, it results in a slightly improved conveyance down Garden Avenue, but does not affect the maximum flow down the North 8th Street line. Overall conveyance through the system is improved by about 23 cfs, and there is no effect on flooding on the PACCAR site. As mentioned above, the swale would reproduce the biofiltration from the existing channel, but there are some uncertainties regarding this option, in- cluding the size of swale which can be built in the space available. These alternatives were run for the 25-year storm as well, and the results are shown in table 3. One of the more important results for this storm is that Alternative 2 does not lead to increased flooding on the PACCAR site for this storm. It is possible that other drainage alternatives may be feasible to achieve the same results, such as replacing one large pipe with two smaller ones, but these were chosen to evaluate options and further design will require more specific information (e.g. sur- vey). A concern about increasing the conveyance through the system is that increases in peak flows will lead to a requirement to provide detention. It is unknown whether the area exists to provide the detention for these alternatives, which would increase the peak flows through the pond system by as much as 82 cfs. The cost for such a facility in this area could be expected to be very significant. COSTS Planning level cost analysis was conducted for the three alternatives. The costs for alternatives 1 and 2 were the same, as the cost of removing the cross connection was assumed to be negligible. Alternatives 1 and 2 were priced out to $1,996,000, and alternative 3 was $2,824,000. These are planning level costs, and are subject to change before final design. Also, there are options which may be as effective at a low- er total cost. The calculations for these costs are shown in Appendix A. 91024-22 Regional Drainage Analysis(64,92)aern 7 Table 3 Comparison of Houser Way Alternatives Alternatives (25-Year Storm) Existing Pipe Only 1 2 3 Height at junction (ft) PACCAR Outfall 3.33 3.34 6.95 5.08 3.20 Pond 1 4.3 0 4.30 4.89 4.98 4.44 Flow in Pipe (cfs) North 8th Street 82.90 82.90 209.00 203.20 82.70 54-inch Garden 47.00 48.90 73.50 62.00 42.00 72-inch Garden 146.80 149.10 169.10 188.90 153.80 North Basin 89.80 90.00 86.00 85.90 89.40 North Houser 20.90 20.90 21.10 21.30 39.60 Pond System 316.70 321.30 391.90 402.20 335.90 Houser Channel 128.80 117.10 117.10 117.10 117.10 Flooding (acre-ft) Houser and 8th St. 13.90 15.60 0.00 0.00 5.40 North Houser 1.40 1.50 1.50 1.50 2.30 PACCAR Site 0.30 0.30 0.50 0.30 0.30 Alternative 1 is the North 8th Street upgrade. Alternative 2 is the North 8th Street upgrade with removal of the cross-connection at North 8th and Garden Avenue. Alternative 3 is the bypass swale. SUMMARY AND CONCLUSIONS There are three alternatives which were evaluated to improve drainage in the vicin- ity of Houser Way. Of these, alternative 2 appears to be superior to alternative 1, as the removal of a cross connection seems to improve drainage in the Garden Avenue li- nes. Alternative 3 does not reduce flooding as much as the other two, but it provides biofiltration and does not affect the drainage off of the PACCAR site. The costs of the first two alternatives is $2,000,000 and the third is $2,820,000. RECOMMENDATIONS FOR FURTHER STUDY There are at least two drainage issues regarding the Houser Way Improvement project which will be important to clarify when proceeding with that project. The first is the previously mentioned drainage/overflow off of the hillside, and the resulting flooding on the valley floor, which must be verified before final design. A second issue is the 91024-22 Regional Drainage Analysis(W4192)aem 8 fact that a portion of the project area currently drains to a bypass pipe which runs through the PACCAR site. Since the flow through the bypass is limited, peak runoff flow rates may be restricted and additional detention may be required in that part of the site. 91024-22 Regional Drainage analysis(WI'W1 —rn 9 Appendix Title Page APPENDIX TITLE LAKE WA5HIWON LEGEND t o FIFE \1UNGT ION 5002 j ® STORAGE JUNCTION 5001 2000 JUNGT ION NIA DU 4002 4001 Q PIPE/OFEN CHANNEL 3002 <.

If other alignments lying west of this alignment were selected then there may be significant impacts. For the current alignment, minor adjustments of the sanitary sewer manholes may be required where the new proposed roadway ties into the existing portions of North 8th Street Houser Way North and Sunset Blvd. North. Neither the current or proposed Comprehensive Plan indicate that new wastewater facilities within the proposed project area due to the fact that the proposed roadway is bounded to the east by 1-405 and to the west by the Burlington Northern Railroad right-of-way. If you have additional questions regarding the wastewater system adjacent to the proposed project, please contact Dave Christensen at X-6212. STORM WATER UTILITY COMMENTS: The Storm Water Utility has a number of concerns with the proposed project alignment. We have scheduled a meeting for your staff on April 10th in the Fire Training Room from 10 AM to 12 noon to provide additional information and to answer questions related to meeting the Core and Special Requirements contained in Chapter 1 of the King County Surface Water Design Manual (KCSWDM) which the City has adopted in Chapter 4-22 of the City Code. Ron Straka has prepared a condensed summary and discussion of these requirements which will likely apply to this project for your review (enclosed). In summary, the Storm Water Utility's concerns with the alignment relate to three areas: the project's additional direct storm water impacts, the project's removal of existing storm water management functions, and several additional potential environmental impacts. Mel Wilson Houser Way Relocation and Extension Page 2 First, the impacts of the increased storm water runoff from this roadway on the downstream drainage system will include increased volume and peak storm water runoff and the generation of additional highway related non-point pollutants into the surface water system. Second, the proposed alignment could have significant adverse impacts to the existing surface water system. The area in which the roadway would be constructed currently conveys and attenuates the storm water flows from a substantial portion (nearly 106 acres) of the North Renton sub-basin (see enclosed map), and from our observations, the wetlands and vegetation in this area act to provide water quality treatment of the storm water flows from this sub-basin. Replacing the existing storm water management functions provided in this area which would be lost is a design element to be addressed in your design studies. Third, the proposed alignment appears to have the following: (1) the construction of the roadway in this alignment will result in the removal of a significant portion of the hillside vegetation which serves a visual buffer between 1-405 and the industrial area; (2) the vegetation and wetland area may provide wildlife and bird habitat that should be considered in the design; and (3) the construction of the roadway at the toe of the slope of the 1-405 embankment may require excavation and construction of a retaining wall. There is reported evidence of groundwater seepage from this area which would be expected given the geology of the Renton Highlands. Groundwater conditions relating to the long term stability of the roadway should be addressed. Addressing the environmental issues will be a part of the environmental review for the project. Reasons for selection of this alignment appears to be an important issue.. Possible alignments to the west may have fewer adverse environmental impacts. We hope additional alignments be identified and addressed in the design studies and in the environmental (SEPA) process. We appreciate this early opportunity to review this proposed project. We have enclosed a brief overview of the storm water quantity and quality control mechanisms with their specific benefits excerpted from the King County Surface Water Design Manual for you and your staff's review prior to our meeting. If you have any questions regarding our comments or recommendations prior to our meeting, please give me a call at X-5548. 91-232:RJS:D MC:RLP:ps CC: Ron Straka Dave Christensen Enclosures HOUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3/15/91 The Houser Way relocation and extension project must satisfy all drainage requirements as specified in the City of Renton Storm and Surface Water Drainage Ordinance chapter 4-22 of the City Code (see enclosed excerpt). This includes complying with the portions of the King County Surface Water Design Manual (KCSWDM) which have been adopted in the Ordinance. The Chapters in the KCSWDM which will need to be reviewed and integrated into the design of the project are Chapters 1 (Section 1.2 and 1.3), 3, 4, and 5, along with the other applicable requirements contained in the Storm and Surface Water Drainage Code. Chapter 1 of the KCSWDM is a summary and guide to all requirements which a project must address. These requirements include Core requirements which all projects must comply with and Special requirements which are specific requirements applied to special drainage concerns. This Chapter should be reviewed early in the preliminary design stage in order to scope out the drainage requirements which apply to the project and would need to be integrated into the project design. Chapters 3, 4 and 5 of the KCSWDM specify how the Core and Special requirements are implemented. The following review will address the requirements listed in Chapter 1 and will be a general description of which requirements likely apply to the project. This review will not constitute a definitive listing of which drainage requirements apply to the project, since there is insufficient detail at this time to be extremely specific, but these comments should provide a good guide for a preliminary design and project scoping study. Core Requirements numbers 1 thru 5 will need to be addressed by this project. Core Requirement No. 1: All surface and storm water runoff from the proposed project that proposed to construct new, or modify existing drainage facilities must be discharged at the natural location so as not to divert flow from the natural drainage course. Enclosed is a map of existing drainage facilities and courses in the projects vicinity along with an outline of the drainage area tributary to the project site. This map shows a natural drainage course for the basin which must be accounted for in project design. Core Requirement No. 2: All proposed projects must identify the upstream tributary drainage area and perform an analysis of the drainage system downstream of the proposed project for a minimum of a quarter of a mile, or to a point on the downstream drainage system where the proposed project site constitutes 15 percent or less of the total tributary drainage area. There are three levels of downstream analysis which could be required. A level one downstream analysis is required with the preliminary design and accompany any environmental review. Upon review of the level 1 downstream analysis a determination will be made by the Storm Water Utility by the Plan Review Section if a Level 2 or 3 downstream analysis is warranted. This report describes the drainage basin, the existing drainage facilities and courses, and the downstream system. The report should describe evidence of existing drainage problems or predict potential drainage problems. Core Requirement No. 3 Proposed projects must provide runoff control by a combination of detention facilities and on-site biofiltration measures. Peak rate runoff control must be provided to limit the developed conditions peak rates of runoff from the 2 and 10 year, 24 hour duration storm events so as to not to exceed the pre-developed peak rate of runoff from the project site existing conditions. If a proposed project site post-developed peak runoff rate for the 100-year, 24-hour duration storm event is greater than 0.5 CFS than the pre-developed peak runoff rate for the same storm from the project site existing runoff conditions, than peak rate runoff control must be provided by either detention, retention or infiltration. The KCSWDM Chapter 3 describes the method of analysis which must be used for each peak rate control facility. Proposed peak rate runoff control facilities must be located on-site. The only exemption to this requirement which could apply to this project is if the discharge of the surface and storm water runoff directly to Lake Washington. An analyses must show that the runoff from the site has an adequate outlet to the Page 1 HOUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3/15/91 lake which will not cause significant adverse impacts such a flooding, water quality degradation. fisheries resources destruction, wetlands impacts and other environmental concerns. All projects which qualify for direct discharge to a receiving body of water or regional facility must meet the requirements of Special requirement No. 5: Special Water Quality Controls. Direct discharge to a Lake, Wetland or Closed Depression must meet the requirements of Special requirement No. 8: Use of Lakes, Wetlands or Closed Depressions for Runoff Control. Proposed project runoff resulting from more than five thousand square feet of impervious surface which is subject to vehicular use or storage of chemicals shall be treated prior to discharge from the project site by on-site biofiltration measures as described in chapter 4 of the KCSWDM. Core Requirement No. 4 All proposed projects must demonstrate that a conveyance system exists, or will be constructed, to convey the peak rate runoff for the 100-year design storm originating on the project site plus any existing upstream runoff that will be conveyed through the project site as to satisfy core requirement No.1. The downstream conveyance system must be analyzed in the off-site drainage analysis in Core requirement No. 2. Surcharged conditions for pipe systems and culverts, and bank full conditions for open ditches and channels are acceptable for demonstrating the adequacy of the conveyance system to convey the peak runoff of the 100-year design storm provided that: Runoff is contained within defined conveyance system elements without inundating or overtopping the crown of the roadway; AND/OR, No portion of a building will be flooded; AND/OR, If overland sheet flow occurs, it will flow through a drainage easement. Permits and approvals requiring drainage review will be exempt from demonstrating that conveyance system exists or will be constructed when the Storm Water Utility determines that the proposed project contains sufficient measures to adequately protect the downstream drainage systems; AND, the project proposes to construct 5,000 square feet, or less, of new impervious surface; AND, collect and concentrate surface and storm water runoff from a drainage area for 5,000 square feet, or less. This project is obviously not exempt from this Core requirement. Conveyance system adequacy shall be demonstrated using the Backwater Analysis Methods described in the KCSWDM chapter 4. In addition to demonstrating adequacy of the conveyance system to convey the peak flows for the 100-year design storm, new conveyance systems/elements proposed by the engineering plan shall be analyzed and sized as follows: New pipe systems: New pipe systems shall be designed to convey and contain at least the peak runoff rate runoff for the 25-year design storm using the Methods of analysis described in section 4.3.4 in chapter 4 of the KCSWDM. Structures for proposed pipe systems must be demonstrated to provide a minimum of 0.5 feet of freeboard between the hydraulic grade line and the top of the structure for the 25-year peak rate of runoff. The system shall then be analyzed for the 100-year design storm. Structures may overtop for the 100-year peak rate of runoff as described above. New Culverts: New culverts shall be designed to convey the peak rate of runoff for the 25-year design storm event using the Methods of analysis for Culverts described in Section 4.3.5 in chapter 4 of the KCSWDM to meet the designated headwater requirements and adequately pass the 100- year storm. New Bridges: New bridges shall be designed to pass the 100-year runoff (estimated for facilities without continuous flow frequency records by using the peak runoff for the 100-year design storm) with clearances as specified in Section 4.3.5 in chapter 4 of the KCSWDM. New Drainage Ditches or Channels: New drainage ditches or channels shall be designed to convey at least the peak runoff from the 25-year design storm using the methods of analysis described in section 4.3.7 in chapter 4 of the KCSWDM with a freeboard to overflow of 0.5 feet. In addition, new drainage ditches or channels must demonstrate to convey the peak runoff from the 100-year storm without overtopping. Page 2 HOUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3/15/91 These are some of the specific requirements of Core requirement No. 4 which the proposed project must satisfy. There are other details contained in Core requirement No. 4 which should be reviewed and addressed in the preliminary design phase.(see page 1.2.4.1 of the KCSWDM) Core Requirement No. 5 All engineering plans for proposed projects that propose to construct new, or modify existing drainage facilities shall include an erosion/sedimentation control plan to prevent sediment-laden runoff from leaving the site during construction. The project must meet the requirements of Core requirement No. 5 as described in Chapter 5 of the KCSWDM. This concludes the review of Core requirements which the Houser Way extension and relocation must satisfy. These Core requirements should be further reviewed by the design engineer to ensure conformance with the Storm and Surface Water Drainage Code. The Special requirements which must be satisfied by the project which we can identify at this time given the available information are as follows: Special Requirement No. 5: If a proposed project will construct more than 1-acre of impervious surface that will be subject to vehicular use of storage of chemicals and: a.) proposes direct discharge of runoff to a regional facility, receiving water, lake, wetland, or closed depression without on-site peak rate runoff control; OR b.) the runoff from the project will discharge into a Type 1 or 2 stream, or Type 1, within one mile from the project site; THEN A wetpond meeting the standards described on page 1.3.5-1 of the KCSWDM shall be employed to treat a projects runoff prior to discharge from the site. A wetvault or water quality swale, as described on page 1.3.5.1 and section 4.6 of chapter 4 of the KCSWDM, may be used when a wetpond is not feasible. This project needs to satisfy this requirement and sufficient planning should be done to ensure the design incorporates a wetpond or wetvault. Special Requirement No. 6 If a proposed project will construct more than 5 acres of impervious surface that will be subject to: a.) petroleum storage or transfer; OR b.) high vehicular use (more than 2,500 vehicle trips per day); OR c.) heavy equipment use, storage or maintenance; THEN A coalescing plate, or equivalent, oil/water separator (as described on page 1.3.6-1 and in section 4.6.4 in chapter 4 of the KCSWDM) shall be employed to treat the project's runoff prior to treatment by a wetpond, wetvault, or water quality swale, and/or discharge from the projects site. The project design shall address this requirement to ensure conformance with the City Drainage Ordinance. Page 3 HOUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3115191 Special Requirement No. 8 If a project proposes to use a lake, wetland or closed depression for the peak rate runoff control consistent with Core requirement No.3; THEN the project must: a.) meet all requirements and regulations which pertain to the use of wetlands and other critical areas b.) include water quality controls consistent with Special requirement No.5: Special Water Quality Controls; AND c.) observe limits on any increased to the floodplain as described on page 1.3.8-1 of the KCSWDM. If this project satisfies the Requirements which will allow exemption of on-site peak rate runoff control measures and direct discharge Lake Washington is feasible/permitted, then this Requirement must be satisfied. SUMMARY: The Houser Way extension and relocation project must satisfy the City of Renton Storm and Surface Water Drainage Ordinance and the adopted portions of the King County Surface Water Design Manual. The King County Surface Water Design Manual Core requirements No. 1 thru 5 must be satisfied along with Special requirements No. 5, 6, and 8. These are the requirements which the Storm Water Utility can identify at this time which are applicable to the project. The Core and Special requirements contained in the King County Surface Water Design Manual along with the the requirements contained in the City Storm and Surface Water Drainage Code should be reviewed during the preliminary feasibility/design study phase of the project to ensure that new information or changed conditions warrant a change in the drainage requirements. The King County Surface Water Design Manual contains additional information which describes the requirements in more detail and should be studied for particular design considerations. If you have any questions regarding this summary, please contact Ron Straka at 277-5547. 91-231:RP:ps Page 4 KING COUNTY, WAS HINGTON, SURFACE WATER DESIGN MANUAL KING COUNTY, WASHINGTON SURFACE WATER DESIGN MANUAL REFERENCE - 4 OVERVIEW OF KING COUNTY SURFACE WATER POLICIES 0 KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Other alternatives to on-site runoff quantity controls may be effective in meeting King County's goals of preserving and protecting natural drainage systems. For example, it may be more hydraulically efficient to discharge stormwater without detention if the site is located close to an acceptable receiving body or a regional facility designed to receive the runoff from the site, and the conveyance system to the water body is adequate and water quality protection measures will be constructed. SURFACE WATER QUANTITY CONTROL POLICY The primary means for King County to minimize the impacts of new development on natural and constructed drainage systems downstream is to require on-site detention facilities to limit the peak rates of runoff from design storm events to levels which exist in the undeveloped state. In most cases, the detention performance curve (described below) will control runoff from most newly developed sites without the need to directly address the increased volume of runoff which results due to the addition of impervious surface. This, however, will not be the case with some sites, for example, where the site discharges to a closed depression or where there is severe downstream erosion potential. - Detention Performance Curve The concept of a detention performance curve was formulated to limit downstream flooding and accelerated erosion resulting from new development. This concept was based on a review of the goals of peak runoff rate controls applied to design storm events of specified return frequencies. Traditionally, control of the less frequent, but higher magnitude, events were addressed in order to prevent downstream flooding. It has now been acknowledged that an even more prevalent, and equally destructive, drainage z problem occurs as the result of new development. This is the accelerated erosion of natural and manmade conveyance systems which occurs from all storms. This is particularly the case for runoff r generated from more frequent storms due to the cumulative "increased work" they apply to the conveyance systems. The "increased work" is the product of the increased flow levels times the extended duration of time which runoff occurs. Hydrograph Methods In order to apply the concept of detention performance as well as the other hydrologic and hydraulic analytical tools, it is essential to have a means of representing the runoff of water leaving a basin at a specific point, over a period of time. The hydrograph method serves this function and, thus, characterizes the surface water runoff from a basin, and from which can be extracted numerical values useful in analysis and design. These values include the total volume, peak rate of runoff, and other values developed from processing the hydrograph through other analytical models such as those representing storage or stream channel routing. The utility of this representation has dictated its selection as the primary tool in estimating the existing and proposed developed runoff characteristics of sites in King County, Design Storm Event Method The method of designing facilities based on hydrographs generated from the application of design storm events has been retained for analyzing existing and designing new drainage facilities. It is acknowledged that methods based on calibrated models utilizing continuous rainfall and streamflow records yield the most accurate results and are essential to analyzing certain complex hydrologic problems. Currently, the data requirements and the complexity and level of effort does not warrant the use of continuous models for the design of most on-site drainage systems in King County. Since the SWM Division is using a continuous model (HSPF, Hydrologic Simulation Program Fortran) for preparing Basin Plans, in all likelihood the use of continuous modeling for design of on-site drainage systems will be phased in over time as Basin Plans are adopted or as special projects arise, in particular very large projects such as Master Drainage Plans. U-5 1/90 i KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Hydrograph Method Selection There were a number of objectives sought in the selection of a "yard stick" methodology for generating runoff hydrographs. The major objectives are listed below: o The method must utilize the design storm event concept. o The method must be easily understandable by practicing civil engineers and BALD Division drainage review staff. o The method is preferably known, at least in part, by current practicing civil engineers in King County. o The method must have easily definable and readily obtainable runoff parameters. o The method must generate consistent, reasonable results through the range of basin areas, and existing and developed runoff characteristics. o The method should be executable manually (although likely much more efficiently through the use of programmable calculators and computers). o The method must produce hydrographs which may be readily processed by other algorithms applying concepts such as storage routing. The combination of the Santa Barbara Urban Hydrograph (SBUH) Method using the Soil Conservation Service (SCS) curve numbers was found to most closely meet these objectives and therefore was selected as the "bench mark" hydrograph methodology. SURFACE WATER QUALITY CONTROL POLICY State-of-the-art measures intended to preserve existing water quality or reduce potential pollutant loadings have been incorporated into many of the requirements of this Manual. These measures include design criteria and requirements such as detention facility performance to control erosive discharges from detention basins, detention basin designs that promote controlled sedimentation, and special water quality controls and vegetation-lined channels for biofiltration. A "Background" discussion is provided at the end of this section which describes some of the research, problems, and regulatory direction on the issues of protecting urban runoff quality. Detention Facility Performance Retention/Detention (R/D) facilities provide flow control by detaining, buffering and attenuating flows. These attributes also provide some level of pollution control by detaining the flow long enough for pollutant removal by physical and/or biochemical processes. They are designed to minimize pollutant discharge so that downstream fisheries, habitat and water quality will be preserved. Because of the direct relationship urban sediment has with pollutants and toxic chemicals, R/D facility design criteria provide control of sediment-laden water and downstream erosion. Control of the 2-year 24 hour duration storm events is needed to provide protection from the cumulative impacts that result in downstream erosion. The need for this protection is supported by recent literature indicating that the level of erosion in a channel is directly proportional to the "work" performed on the channel by flowing water. The dominant flow, defined as channel dominant discharge, is the most effective in performing this 'Work" and has been found to be in the range of a 1 - 2 year return frequency flow, or an approximate bank-full channel condition. Results of recent studies have demonstrated that substantial removals of pollutants in urban stormwater can be achieved by gravity sedimentation if turbulent mixing can be avoided and the detention time is long. The pollutants most susceptible to removal are Total Suspend Solids (TSS), hydrocarbons, lead, Biological Oxygen Demand (BOD), and total phosphates. Trap efficiencies of 70 percent of TSS, hydrocarbons and lead; 50 percent of BOD and phosphates: and at least 33 percent of chemical Oxygen 0-6 1/90 rw KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Demand (COD), Total Organic Carbon (TOC), and Total Nitrogen (TN) were reported in the studies. TSS is particularly susceptible to removal by sedimentation and can also be representative of the amount of general pollution due to their affinity for absorbing numerous other pollutants. The most important feature for water quality R/D facility design is to promote siltation by providing maximum detention time of the ponded urban runoff. The hydrologic performance concept for R/D design described previously is primarily for controlling downstream erosion and flood events, but its inherent design also provides long detention times and is therefore ideally suited for water quality control. Computer model test cases run by SWM staff for average development conditions resulted in detention times of approximately 30 hours for the 2-year, 24-hour storm. Additional R/D facility design features generally required to promote sedimentation, infiltration, and biofiltration include: o Utilization of long, narrow pond configurations. The minimum required length/width ratio is two; larger ratios are encouraged. o Installation of inlet and outlet structures at extreme ends of the pond. o Flat pond and tank/vault bottoms provide for minimum flow velocity to promote settlement and biofiltration (in ponds). o Provision of water tolerant, stable vegetative ground cover on pond bottom and sides controls erosion and provides biofiltration. o Provision of 6-inch-deep sediment sump (dead storage) over pond and tank/vault bottom area. o Two-cell pond design. Special Water Quality Controls There are two types of special water quality control facilities provided in this Manual to treat surface water runoff. These are wet ponds and vaults, and water quality swales. They are primarily required to treat runoff from developed areas prior to discharge to sensitive natural drainage features such as wetlands, lakes and streams (when not treated by a retention/detention pond), and prior to infiltration. Both of these types of facilities utilize sedimentation, biofiltration and biologic activity as the mechanisms for removal of pollutants from surface water runoff and have been demonstrated to provide substantial water quality improvements by a number of studies. The SWM Division will continue to participate in on-going programs to further substantiate and quantify the benefits these facilities provide, as well as refine the analytic methods and criteria for their design- Vegetation-Lined Swales and Native Growth Areas Vegetation-lined swales (often referred to a grass-lined channels), when properly designed, have been proven effective as "biofiltration" mechanisms for the removal of sediments, heavy metals, and some nutrients from stormwater leaving developed areas. Suspended particles can settle out if the velocity of flow is slowed over an adequate length of channel and, depending on soil type, infiltration will also provide water quality benefits. The optimum design of vegetation-lined swales minimizes water depth and velocity to promote maximum water contact with channel vegetation and infiltration. The preservation of native growth areas is also very important in preserving water quality, as well as environmental features necessary to protect valuable natural resources and maintain stable slopes. Water quality benefits from these native growth areas are both direct and indirect by providing for pollutant reduction or elimination, and provide physical protection of aesthetics and wildlife habitat. For example, natural vegetative corridors along streams or around wetlands provide biofiltration to incoming pollutants and preserve the aquatic and wildlife habitat along the water's edge. O-7 1/90 KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Background Discharge of stormwater runoff into surface water can result in water quality degradation of the natural surface water system. For example, the Bellevue National Urban Runoff Program (Pitt and Bissonnette, 1984) stated the following stormwater related impacts to a local stream in an urbanizing area: o Reduction in diversity of aquatic species. o Physiological damage to fish populations o Periodic fish kills associated with dumping of toxic substances into the drainage system o Higher water temperature o Channel instability and increased sediment transport o Increased fecal coliform bacteria populations o Reduced aesthetic value Water quality degradation may be acute or chronic. A fishkill is an acute reaction to dumping of a toxic substance (such as antifreeze) into a catchbasin discharging to a stream. Chronic degradation may also include the gradual accumulation of pollutants (including combustion engine by-products such as cadmium, zinc, and lead) which in turn may contribute to a reduction in the diversity of species and physiological damage to the species that remain. Pollutants in urban runoff are usually attached to sediments. In addition, sediments clog and cement spawning gravels and reduce the capacity of conveyance systems. Control of sediment during all phases of urbanization (construction through full development) is therefore critical to reducing the discharge of pollutants to the County's surface waters. Consequently, the County requires all new development to prepare a plan for the control erosion and sedimentation both during and after construction, (see Requirement #5). In the coming years, there will be growing local state and federal emphasis on the control of water quality. The recently completed 1987 Puget Sound Water Quality Plan, underscores the need for basin planning and controlling the discharge of stormwater pollutants at the source. During the next 5 years the Environmental protection Agency and the State of Washington Department of Ecology will be preparing the requirements for a County-wide permit (under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) program) which will set acceptable levels of stormwater pollutants discharged into the County's surface waters. In response to these programs and King County's own goals for enhancement and preservation of environmental quality, King County will continue to review and update its requirements for the protection of water quality to ensure environmental preservation of our water resources. 0.8 1/90 CONCURRENCE CITY OF RENTON DATE..; 1 IN711AU,�DATE 31-4 MEMORANDUM ze JQ-- DATE: April 3, 1991 TO: Mel Wilson VIA: Dick Anderson FROM: Randall Parsons STAFF CONTACT: Ron Straka Dave Christensen SUBJECT: HOUSER WAY RELOCATION AND EXTENSION STORM AND WASTEWATER UTILITY REVIEW WASTEWATER UTILITY COMMENTS: The project proposal will have only a minor impact on the waste water system if the current alignment is implemented. If other alignments lying west of this alignment were selected then there may be significant impacts. For the current alignment, minor adjustments of the sanitary sewer manholes may be required where the new proposed roadway ties into the existing portions of North 8th Street Houser Way North and Sunset Blvd. North. Neither the current or proposed Comprehensive Plan indicate that new wastewater facilities within the proposed project area due to the fact that the proposed roadway is bounded to the east by 1-405 and to the west by the Burlington Northern Railroad right-of-way. If you have additional questions regarding the wastewater system adjacent to the proposed project, please contact Dave Christensen at X-6212. STORM WATER UTILITY COMMENTS: The Storm Water Utility has a number of concerns with the proposed project alignment. We have scheduled a meeting for your staff on April 10th in the Fire Training Room from 10 AM to 12 noon to provide additional information and to answer questions related to meeting the Core and Special Requirements contained in Chapter 1 of the King County Surface Water Design Manual (KCSWDM) which the City has adopted in Chapter 4-22 of the City Code. Ron Straka has prepared a condensed summary and discussion of these requirements which will likely apply to this project for your review (enclosed). In summary, the Storm Water Utility's concerns with the alignment relate to three areas: the project's additional direct storm water impacts, the project's removal of existing storm water management functions, and several additional potential environmental impacts. Mel Wilson Houser Way Relocation and Extension Page 2 First, the impacts of the increased storm water runoff from this roadway on the downstream drainage system will include increased volume and peak storm water runoff and the generation of additional highway related non-point pollutants into the surface water system. Second, the proposed alignment could have significant adverse impacts to the existing surface water system. The area in which the roadway would be constructed currently conveys and attenuates the storm water flows from a substantial portion (nearly 106 acres) of the North Renton sub-basin (see enclosed map), and from our observations, the wetlands and vegetation in this area act to provide water quality treatment of the storm water flows from this sub-basin. Replacing the existing storm water management functions provided in this area which would be lost is a design element to be addressed in your design studies. Third, the proposed alignment appears to have the following: (1) the construction of the roadway in this alignment will result in the removal of a significant portion of the hillside vegetation which serves a visual buffer between 1-405 and the industrial area; (2) the vegetation and wetland area may provide wildlife and bird habitat that should be considered in the design; and (3) the construction of the roadway at the toe of the slope of the 1-405 embankment may require excavation and construction of a retaining wall. There is reported evidence of groundwater seepage from this area which would be expected given the geology of the Renton Highlands. Groundwater conditions relating to the long term stability of the roadway should be addressed. Addressing the environmental issues will be a part of the environmental review for the project. Reasons for selection of this alignment appears to be an important issue. Possible alignments to the west may have fewer adverse environmental impacts. We hope additional alignments be identified and addressed in the design studies and in the environmental (SEPA) process. We appreciate this early opportunity to review this proposed project. We have enclosed a brief overview of the storm water quantity and quality control mechanisms with their specific benefits excerpted from the King County Surface Water Design Manual for you and your staff's review prior to our meeting.

The draft drainage report adequately addresses Core Requirements #1 , #2, and a portion of #3. Biofiltration will be required per Core Requirement #3 because the project will be constructing more than 5,000 square feet of new impervious surface that will be subject to vehicular use. Since the design will utilize open ditches and channels for the new conveyance system, and as there appears to be adequate area, this requirement should be readily met without substantial additional costs for the project. The following information should be added to the draft drainage report to allow us to evaluate how Core Requirement #4 will be met: 1) Calculations for Times of Concentration (Tc), per King County Surface Water Design Manual used for computing the peak flows for each subbasin, shown in the Appendix. Further document the results that were obtained for the output files Basin 1-9.25, Basin 1-9.100, and Sum (30,36,48).25 and Sum (30,36,48).100 # - —'+ 2) Showing that the existing conveyance system in the project area has capacity for a 25 year design storm event. This requirement is per Core Requirement #4. Provide backwater calculations for all conveyance storm lines within the project area, and use either the Rational method (if the contributing area is less than 25 acres) and the Santa Barbara Urban Hydrograph method (if the contributing basin is greater than 25 acres) for computing peak runoff, and also enclose Tc calculations for both Rational and Santa Barbara Hydrograph methods. 3) Sizing calculations for sediment trap(s) shall be provided, per Chapter 5, 1990 KCSWD Manual, that fulfills Core Requirement #5. 111191-378:KDS:ps CC: Dick Anderson Gregg Zimmerman . . , ^ ' C C: \KCSWM> SBUH/SCS METHOD FOR COMPUTING RUNOFF HYDROGRAPH STORM OPTIONS: 1 - S.

OCT 131 im� dy to Address Development West of I-405 MANAGEMENT & PLANNING (Garden Plaza - Park Plaza) SERVICES May 1988 , /�i « �-.�, Introduction An analysis (using SCS TR-55 Program) determining the expected flows at the intersection of Garden Avenue N and N 8th Street produced a peak flow of 223.39 c.f.s. based on a 25 year storm event. The 48" reinforced concrete pipe (RCP) running down Garden Avenue N between N 8th Street and Lake Washington Boulevard is grossly inadequate for carrying this flow and the system must be upgraded. In order to have sufficient capacity to carry this flow, a parallel 66" RCP (or material with similar flow characteristics) is required. The length of system to be contributed by the Garden and Park Plaza (see Figure 1) projects was computed using the existing system capacity for allowable outfall and a 25 year design storm. The necessary volume was determined as 18,774 ft3 which corresponds to approximately 790 I.f. of 66" pipe. To maximize the early benefit, the pipe contributions should be started on the lower end of the system and worked upstream. In lieu of on-site detention, this contribution will be added to as further development continues in the Iower portion of the North Renton Basin. That portion of the basin which lies cast of SR 405 would remain as an on-site detention region with any drainage problems on this side being corrected by regional detention rather than by upgrading the I-405 crossings. Basin Charneteristics The North Renton Basin contains approximately 773 acres consisting of two regions with vastly different characteristics. These regions are separated by 1-405. The upper basin area to the east of I-405 is the Highlands region. The lower basin area west of I-405 is the Valley region. 1 • f The Highlands region is roughly bordered by Sunset Boulevard on the north, NE 4th Street on the south, Monroe Avenue NE on the East, and I-405 on the west. This region slopes down to the west at approximately 5 percent. While development consists mainly of residential, there are some smaller areas covered with apartments, commercial sites, and schools. Soils characteristics vary anywhere between Type A to Type C (reference; Soils Survey King County Area Washington, United States Department of Agriculture Soils Conservation Service, Nov. 1973.) The Highlands region discharges into the Valley region through several culverts crossing under I-405. Flows are transported from the Highlands region through the Valley region out to Lake Washington. The Valley region is bordered by 1-405 on the east, Burnett Avenue N on the west, N 4th Street on the south, and Lake Washington on the north. This region has flat slopes and is highly industrialized with a small percentage of residential. The soils category consists of Type C. There are two points of discharge (see Figure 2) from the Valley region. The majority of the flow is discharged through the 48" concrete pipe running north along Garden Avenue N from N 801 Street to Lake Washington Boulevard. From there it discharges through a series of other culverts and open ditches until it reaches Lake Washington. The second outfall is a 24" concrete line running from the end of N 7th Street out to the Cedar River. Due to the shallow slope, the capacity of this line is inadequate, even considering the maximum available head. For this reason, the two systems are interconnected such that the flow which does not flow down the 24" line will backflow into the 48" line running down Garden Avenue N. Page 2 of 5 • Y L' 1 Peak 25 Year Flow Analysis The North Renton Basin was broken up into 11 separate subbasins (see Figure 2) due to topography, existing storm systems, and critical flow control points. The control points were crossings of I-405 and major storm drainage intersection points where one system was joined by another. :' '. Due to time restrictions, it was decided that the peak 25 year flow analysis would be done on the SCS TR-55 Program. Existing and future "CN" values were developed using U.S.G.S. soils maps, aerial photographs, and February 1988 zoning maps (see Figure 3). The travel times and times of concentration were calculated using available information on existing storm systems and topographical information from 1968 City of Renton topographical maps. Running the CN value, time of concentration, and travel time through the TR-55 program for each of the 11 subbasins, the peak 25 year flow at the outlet point of the intersection of Garden Avenue N and N 8th Street from the North Renton Basin was calculated to be 289.22 c.f.s. Upon further study of the flow control points, it was found that Areas 1, 2, and 3 flowed to n 21" Cl' with the maximum capacity of 30 c.f.s. The flows exceeded this volume starting at the 7.9 hour mark at which point the excess flow would take an alternate path to the outlet point.. The excess flow (that above 30 c.f.s.) was lagged by approximately 1/2 hour, which is the time determined for the flow to run down Sunset Blvd, cross 1-405 through the 30" CMP and travel in a ditch along the west side of I-405 to a point joining the original flow path. The resulting peak flow was calculated to be 202.0 c.f.s. When a similar adjustment was performed for area No. 6, the peak flow was found to be 199.1 c.f.s. Pnge 3 of 5 The peak flow which is required to flow down the Garden Avenu N storm line would be the computed peak flow subtracted by the capacity of the 24" CP outfall to the Cedar River. This will yield 186.9 c.f.s. as the necessary volume of flow which the system must eventually carry. j. Existing Capacity The storm line running down Garden consists of approximately 2,375 IS. of 48" RCP with seven manholes in between. Calculating the capacity, using Manning's equation, under full bend conditions (headwater at Roadway surface), a maximum flow of 93 c.f.s. will flow through. Through trial and error on the TR-55, a rainfall of 2.0 inches, corresponding to a 2 year storm, yields n peak flow down Garden Avenue N of 93.2 c.f.s. which is the approximate capacity of the system in question. For calculation of development contribution, the 2 year storm will be the allowable outlet criteria based on the existing systems capacity. Upgrade Line Size Based upon the computed capacity of the existing line down Garden Avenue N and the computed peak 25 year flow, using Mnnning's equation, it was determined that n 66" pipe with nn "n" value of 0.012 is required to parallel the existing 48" RCP. A head of 5.3' is needed to push the 25 year flow through this parallel system of pipes which will discharge into the ponding area on the south side of Lake Washington Boulevard before crossing beneath the road via two 48" CP culverts. Contribution by Park and Garden Plaza On-site detention required for the Park Plaza and Garden Plaza projects was calculated using a 25 year storm with the release rate restricted to the capacity of the existing system (2 year storm). For Pape 4 of. 5 simplification purposes, all three sites were combined as one with an average CN and the longest Tc taken for the site. The combined sites resulted in an area of 10.4 acres, CN of 92, and the longest Tc being 16 min. Running the calculated numbers through the SCS TR-20 program, a predevelopment 2 year now of 3.02 c.f.s. was computed. For post development conditions, the same Tc and a CN of 98 were assumed. Passing the post development flows through a simulated detention system (using n structure and reservoir card based on a 66" pipe with a single orifice and overflow at the top of the pipe), successive runs were performed increasing the length of the pipe until the maximum outflow of 3.02 c.f.s. was attained without encountering overflow conditions. The necessary volume to fit these conditions is 18,774 ft3 of detention. This corresponds to approximately 790 l.f. of 66" pipe which is required, in lieu of on-site detention, to fulfill the requirements.

If other alignments lying west of this alignment were selected then there may be significant impacts. For the current alignment, minor adjustments of the sanitary sewer manholes may be required where the new proposed roadway ties into the existing portions of North 8th Street Houser Way North and Sunset Blvd. North. Neither the current or proposed Comprehensive Plan indicate that new wastewater facilities within the proposed project area due to the fact that the proposed roadway is bounded to the east by 1-405 and to the west by the Burlington Northern Railroad right-of-way. If you have additional questions regarding the wastewater system adjacent to the proposed project, please contact Dave Christensen at X-6212. STORM WATER UTILITY COMMENTS: The Storm Water Utility has a number of concerns with the proposed project alignment. We have scheduled a meeting for your staff on April 10th in the Fire Training Room from 10 AM to 12 noon to provide additional information and to answer questions related to meeting the Core and Special Requirements contained in Chapter 1 of the King County Surface Water Design Manual (KCSWDM) which the City has adopted in Chapter 4-22 of the City Code. Ron Straka has prepared a condensed summary and discussion of these requirements which will likely apply to this project for your review (enclosed). In summary, the Storm Water Utility's concerns with the alignment relate to three areas: the project's additional direct storm water impacts, the project's removal of existing storm water management functions, and several additional potential environmental impacts. Mel Wilson Houser Way Relocation and Extension Page 2 First, the impacts of the increased storm water runoff from this roadway on the downstream drainage system will include increased volume and peak storm water runoff and the generation of additional highway related non-point pollutants into the surface water system. Second, the proposed alignment could have significant adverse impacts to the existing surface water system. The area in which the roadway would be constructed currently conveys and attenuates the storm water flows from a substantial portion (nearly 106 acres) of the North Renton sub-basin (see enclosed map), and from our observations, the wetlands and vegetation in this area act to provide water quality treatment of the storm water flows from this sub-basin. Replacing the existing storm water management functions provided in this area which would be lost is a design element to be addressed in your design studies. Third, the proposed alignment appears to have the following: 0 ) the construction of the roadway in this alignment will result in the removal of a significant portion of the hillside vegetation which serves a visual buffer between 1-405 and the industrial area; (2) the vegetation and wetland area may provide wildlife and bird habitat that should be considered in the design; and (3) the construction of the roadway at the toe of the slope of the 1-405 embankment may require excavation and construction of a retaining wall. There is reported evidence of groundwater seepage from this area which would be expected given the geology of the Renton Highlands. Groundwater conditions relating to the long term stability of the roadway should be addressed. Addressing the environmental issues will be a part of the environmental review for the project. Reasons for selection of this alignment appears to be an important issue. Possible alignments to the west may have fewer adverse environmental impacts. We hope additional alignments be identified and addressed in the design studies and in the environmental (SEPA) process. We appreciate this early opportunity to review this proposed project. We have enclosed a brief overview of the storm water quantity and quality control mechanisms with their specific benefits excerpted from the King County Surface Water Design Manual for you and your staff's review prior to our meeting. If you have any questions regarding our comments or recommendations prior to our meeting, please give me a call at X-5548. 91-232:RJS:D MC:R LP:ps CC: Ron Straka Dave Christensen Enclosures 3M l I Lett) �St1Nv` �J 1�m '♦ �t 17-am / -ytrCt. 4-9trC° [ t-Pf2 \ -BJt Z-aJt[ [-9atS ,"�` ♦-97tt I s-a1fA `JC a--erttt { I L _patt t-6xt C-om ti a-Mt s eatt \ \ c att 3N \ t-am C-axl ttt I dr /• -owat T I , i Li a-csct [--- t I � � C-Grzt 1 L-Galt a-utt - I � n G3Ct Gatt cat[ cxs-J V.\ -cast tat[ s-tat rcnl 4 \ 3 L_J 11-M { at- ' a-carat crrl a-crr{ "9121 t-91•at r L-*nl - hsm 9-9Hz{ HA[ I C-sl•at r 9-s92[ s-sat[ C-93tt. a-siz 1 IryJ � L-9fat s-satt C-9ati �s ►-rr:l \ s-sm t_9 a-sat[ I , �- xt \ a-satt t CC�tt 1S c-stratr arm �S 1-9a'Ct � : •\ ' c-9tat a-rr+[ . t� . 1-91rat t-wnt •\ l ♦-SJtt tt t"c�'at s Hy8 a I � ys C-snl seta �\-sfat c-t3rat {•c; I his 9-sm c-eJat n�lti i n �+ c sxat et tsar � n-rrat a tt ¢=s sari a sat[ can w6 c-sRt swat yo HAB at e-c •I �r—. HOUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3/15/91 The Houser Way relocation and extension project must satisfy all drainage requirements as specified in the City of Renton Storm and Surface Water Drainage Ordinance chapter 4-22 of the City Code (see enclosed excerpt). This includes complying with the portions of the King County Surface Water Design Manual (KCSWDM) which have been adopted in the Ordinance. The Chapters in the KCSWDM which will need to be reviewed and integrated into the design of the project are Chapters 1 (Section 1.2 and 1.3), 3, 4, and 5, along with the other applicable requirements contained in the Storm and Surface Water Drainage Code. Chapter 1 of the KCSWDM is a summary and guide to all requirements which a project must address. These requirements include Core requirements which all projects must comply with and Special requirements which are specific requirements applied to special drainage concerns. This Chapter should be reviewed early in the preliminary design stage in order to scope out the drainage requirements which apply to the project and would need to be integrated into the project design. Chapters 3, 4 and 5 of the KCSWDM specify how the Core and Special requirements are implemented. The following review will address the requirements listed in Chapter 1 and will be a general description of which requirements likely apply to the project. This review will not constitute a definitive listing of which drainage requirements apply to the project, since there is insufficient detail at this time to be extremely specific, but these comments should provide a good guide for a preliminary design and project scoping study. Core Requirements numbers 1 thru 5 will need to be addressed by this project. Core Requirement No. 1: All surface and storm water runoff from the proposed project that proposed to construct new, or modify existing drainage facilities must be discharged at the natural location so as not to divert flow from the natural drainage course. Enclosed is a map of existing drainage facilities and courses in the projects vicinity along with an outline of the drainage area tributary to the project site. This map shows a natural drainage course for the basin which must be accounted for in project design. Core Requirement No. 2: All proposed projects must identify the upstream tributary drainage area and perform an analysis of the drainage system downstream of the proposed project for a minimum of a quarter of a mile, or to a point on the downstream drainage system where the proposed project site constitutes 15 percent or less of the total tributary drainage area. There are three levels of downstream analysis which could be required. A level one downstream analysis is required with the preliminary design and accompany any environmental review. Upon review of the level 1 downstream analysis a determination will be made by the Storm Water Utility by the Plan Review Section if a Level 2 or 3 downstream analysis is warranted. This report describes the drainage basin, the existing drainage facilities and courses, and the downstream system. The report should describe evidence of existing drainage problems or predict potential drainage problems. Core Requirement No. 3 Proposed projects must provide runoff control by a combination of detention facilities and on-site biofiltration measures. Peak rate runoff control must be provided to limit the developed conditions peak rates of runoff from the 2 and 10 year, 24 hour duration storm events so as to not to exceed the pre-developed peak rate of runoff from the project site existing conditions. If a proposed project site post-developed peak runoff rate for the 100-year, 24-hour duration storm event is greater than 0.5 CFS than the pre-developed peak runoff rate for the same storm from the project site existing runoff conditions, than peak rate runoff control must be provided by either detention, retention or infiltration. The KCSWDM Chapter 3 describes the method of analysis which must be used for each peak rate control facility. Proposed peak rate runoff control facilities must be located on-site. The only exemption to this requirement which could apply to this project is if the discharge of the surface and storm water runoff directly to Lake Washington. An analyses must show that the runoff from the site has an adequate outlet to the Page 1 HQUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3/15/91 lake which will not cause significant adverse impacts such a flooding, water quality degradation. fisheries resources destruction, wetlands impacts and other environmental concerns. All projects which qualify for direct discharge to a receiving body of water or regional facility must meet the requirements of Special requirement No. 5: Special Water Quality Controls. Direct discharge to a Lake, Wetland or Closed Depression must meet the requirements of Special requirement No. 8: Use of Lakes, Wetlands or Closed Depressions for Runoff Control. Proposed project runoff resulting from more than five thousand square feet of impervious surface which is subject to vehicular use or storage of chemicals shall be treated prior to discharge from the project site by on-site biofiltration measures as described in chapter 4 of the KCSWDM. Core Requirement No. 4 All proposed projects must demonstrate that a conveyance system exists, or will be constructed, to convey the peak rate runoff for the 100-year design storm originating on the project site plus any existing upstream runoff that will be conveyed through the project site as to satisfy core requirement No.1. The downstream conveyance system must be analyzed in the off-site drainage analysis in Core requirement No. 2. Surcharged conditions for pipe systems and culverts, and bank full conditions for open ditches and channels are acceptable for demonstrating the adequacy of the conveyance system to convey the peak runoff of the 100-year design storm provided that: Runoff is contained within defined conveyance system elements without inundating or overtopping the crown of the roadway; AND/OR, No portion of a building will be flooded; AND/OR, If overland sheet flow occurs, it will flow through a drainage easement. Permits and approvals requiring drainage review will be exempt from demonstrating that conveyance system exists or will be constructed when the Storm Water Utility determines that the proposed project contains sufficient measures to adequately protect the downstream drainage systems; AND, the project proposes to construct 5,000 square feet, or less, of new impervious surface; AND, collect and concentrate surface and storm water runoff from a drainage area for 5,000 square feet, or less. This project is obviously not exempt from this Core requirement. Conveyance system adequacy shall be demonstrated using the Backwater Analysis Methods described in the KCSWDM chapter 4. In addition to demonstrating adequacy of the conveyance system to convey the peak flows for the 100-year design storm, new conveyance systems/elements proposed by the engineering plan shall be analyzed and sized as follows: New pipe systems: New pipe systems shall be designed to convey and contain at least the peak runoff rate runoff for the 25-year design storm using the Methods of analysis described in section 4.3.4 in chapter 4 of the KCSWDM. Structures for proposed pipe systems must be demonstrated to provide a minimum of 0.5 feet of freeboard between the hydraulic grade line and the top of the structure for the 25-year peak rate of runoff. The system shall then be analyzed for the 100-year design storm. Structures may overtop for the 100-year peak rate of runoff as described above. New Culverts: New culverts shall be designed to convey the peak rate of runoff for the 25-year design storm event using the Methods of analysis for Culverts described in Section 4.3.5 in chapter 4 of the KCSWDM to meet the designated headwater requirements and adequately pass the 100- year storm. New Bridges: New bridges shall be designed to pass the 100-year runoff (estimated for facilities without continuous flow frequency records by using the peak runoff for the 100-year design storm) with clearances as specified in Section 4.3.5 in chapter 4 of the KCSWDM. New Drainage Ditches or Channels: New drainage ditches or channels shall be designed to convey at least the peak runoff from the 25-year design storm using the methods of analysis described in section 4.3.7 in chapter 4 of the KCSWDM with a freeboard to overflow of 0.5 feet. In addition, new drainage ditches or channels must demonstrate to convey the peak runoff from the 100-year storm without overtopping. Page 2 HOUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3/15/91 These are some of the specific requirements of Core requirement No. 4 which the proposed project must satisfy. There are other details contained in Core requirement No. 4 which should be reviewed and addressed in the preliminary design phase.(see page 1.2.4.1 of the KCSWDM) Core Requirement No. 5 All engineering plans for proposed projects that propose to construct new, or modify existing drainage facilities shall include an erosion/sedimentation control plan to prevent sediment-laden runoff from leaving the site during construction. The project must meet the requirements of Core requirement No. 5 as described in Chapter 5 of the KCSWDM. This concludes the review of Core requirements which the Houser Way extension and relocation must satisfy. These Core requirements should be further reviewed by the design engineer to ensure conformance with the Storm and Surface Water Drainage Code. The Special requirements which must be satisfied by the project which we can identify at this time given the available information are as follows: Special Requirement No. 5: If a proposed project will construct more than 1-acre of impervious surface that will be subject to vehicular use of storage of chemicals and: a.) proposes direct discharge of runoff to a regional facility, receiving water, lake, wetland, or closed depression without on-site peak rate runoff control; OR b.) the runoff from the project will discharge into a Type 1 or 2 stream, or Type 1, within one mile from the project site; THEN A wetpond meeting the standards described on page 1 .3.5-1 of the KCSWDM shall be employed to treat a projects runoff prior to discharge from the site. A wetvault or water quality swale, as described on page 1.3.5.1 and section 4.6 of chapter 4 of the KCSWDM, may be used when a wetpond is not feasible. This project needs to satisfy this requirement and sufficient planning should be done to ensure the design incorporates a wetpond or wetvault. Special Requirement No. 6 If a proposed project will construct more than 5 acres of impervious surface that will be subject to: a.) petroleum storage or transfer; OR b.) high vehicular use (more than 2,500 vehicle trips per day); OR c.) heavy equipment use, storage or maintenance; THEN A coalescing plate, or equivalent, oil/water separator (as described on page 1.3.6-1 and in section 4.6.4 in chapter 4 of the KCSWDM) shall be employed to treat the project's runoff prior to treatment by a wetpond, wetvault, or water quality swale, and/or discharge from the projects site. The project design shall address this requirement to ensure conformance with the City Drainage Ordinance. Page 3 HOUSER WAY RELOCATION AND EXTENSION PROJECT Summary of Storm Water Requirements: Ron Straka 3115191 Special Requirement No. 8 If a project proposes to use a lake, wetland or closed depression for the peak rate runoff control consistent with Core requirement No.3; THEN the project must: a.) meet all requirements and regulations which pertain to the use of wetlands and other critical areas b.) include water quality controls consistent with Special requirement No.5: Special Water Quality Controls; AND c.) observe limits on any increased to the floodplain as described on page 1.3.8-1 of the KCSWDM. If this project satisfies the Requirements which will allow exemption of on-site peak rate runoff control measures and direct discharge Lake Washington is feasible/permitted, then this Requirement must be satisfied. SUMMARY: The Houser Way extension and relocation project must satisfy the City of Renton Storm and Surface Water Drainage Ordinance and the adopted portions of the King County Surface Water Design Manual. The King County Surface Water Design Manual Core requirements No. 1 thru 5 must be satisfied along with Special requirements No. 5, 6, and 8. These are the requirements which the Storm Water Utility can identify at this time which are applicable to the project. The Core and Special requirements contained in the King County Surface Water Design Manual along with the the requirements contained in the City Storm and Surface Water Drainage Code should be reviewed during the preliminary feasibility/design study phase of the project to ensure that new information or changed conditions warrant a change in the drainage requirements. The King County Surface Water Design Manual contains additional information which describes the requirements in more detail and should be studied for particular design considerations. If you have any questions regarding this summary, please contact Ron Straka at 277-5547. 91-231:RP:ps Page 4 ` KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL KING COUNTY, WASHINGTON SURFACE WATER DESIGN MANUAL REFERENCE - 4 OVERVIEW OF KING COUNTY SURFACE WATER POLICIES 00 ' KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Other alternatives to on-site runoff quantity controls may be effective in meeting King County's goals of preserving and protecting natural drainage systems. For example, it may be more hydraulically efficient to discharge stormwater without detention if the site is located close to an acceptable receiving body or a regional facility designed to receive the runoff from the site, and the conveyance system to the water body is adequate and water quality protection measures will be constructed. SURFACE WATER QUANTITY CONTROL POLICY The primary means for King County to minimize the impacts of new development on natural and constructed drainage systems downstream is to require on-site detention facilities to limit the peak rates of runoff from design storm events to levels which exist in the undeveloped state. In most cases, the detention performance curve (described below) will control runoff from most newly developed sites without the need to directly address the increased volume of runoff which results due to the addition of impervious surface. This, however, will not be the case with some sites, for example, where the site discharges to a closed depression or where there is severe downstream erosion potential. Detention Performance Curve The concept of a detention performance curve was formulated to limit downstream flooding and accelerated erosion resulting from new development. This concept was based on a review of the goals of peak runoff rate controls applied to design storm events of specified return frequencies. Traditionally, control of the less frequent, but higher magnitude, events were addressed in order to prevent downstream flooding. It has now been acknowledged that an even more prevalent, and equally destructive, drainage problem occurs as the result of new development. This is the accelerated erosion of natural and manmade conveyance systems which occurs from all storms. This is particularly the case for runoff F generated from more frequent storms due to the cumulative "increased work" they apply to the conveyance systems. The "increased work" is the product of the increased flow levels times the extended duration of time which runoff occurs. Hydrograph Methods In order to apply the concept of detention performance as well as the other hydrologic and hydraulic analytical tools, it is essential to have a means of representing the runoff of water leaving a basin at a specific point, over a period of time. The hydrograph method serves this function and, thus, characterizes the surface water runoff from a basin, and from which can be extracted numerical values useful in analysis and design. These values include the total volume, peak rate of runoff, and other values developed from processing the hydrograph through other analytical models such as those representing storage or stream channel routing. The utility of this representation has dictated its selection as the primary tool in estimating the existing and proposed developed runoff characteristics of sites in King County. Design Storm Event Method The method of designing facilities based on hydrographs generated from the application of design storm events has been retained for analyzing existing and designing new drainage facilities. It is acknowledged that methods based on calibrated models utilizing continuous rainfall and streamflow records yield the most accurate results and are essential to analyzing certain complex hydrologic problems. Currently, the data requirements and the complexity and level of effort does not warrant the use of continuous models for the design of most on-site drainage systems in King County. Since the SWM Division is using a continuous model (HSPF, Hydrologic Simulation Program Fortran) for preparing Basin Plans, in all likelihood the use of continuous modeling for design of on-site drainage systems will be phased in over time as Basin Plans are adopted or as special projects arise, in particular very large projects such as Master Drainage Plans. O-5 1/90 E E KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Hydrograph Method Selection There were a number of objectives sought in the selection of a "yard stick" methodology for generating runoff hydrographs. The major objectives are listed below: o The method must utilize the design storm event concept. o The method must be easily understandable by practicing civil engineers and BALD Division drainage review staff. o The method is preferably known, at least in part, by current practicing civil engineers in King County. o The method must have easily definable and readily obtainable runoff parameters. o The method must generate consistent, reasonable results through the range of basin areas, and existing and developed runoff characteristics. o The method should be executable manually (although likely much more efficiently through the use of programmable calculators and computers). F o The method must produce hydrographs which may be readily processed by other algorithms applying concepts such as storage routing. The combination of the Santa Barbara Urban Hydrograph (SBUH) Method using the Soil Conservation Service (SCS) curve numbers was found to most closely meet these objectives and therefore was selected as the "bench mark" hydrograph methodology. SURFACE WATER QUALITY CONTROL POLICY State-of-the-art measures intended to preserve existing water quality or reduce potential pollutant loadings have been incorporated into many of the requirements of this Manual. These measures include design criteria and requirements such as detention facility performance to control erosive discharges from detention basins, detention basin designs that promote controlled sedimentation, and special water quality controls and vegetation-lined channels for biofiltration. A "Background" discussion is provided at the end of this section which describes some of the research, problems, and regulatory direction on the issues of protecting urban runoff quality. Detention Facility Performance Retention/Detention (R/D) facilities provide flow control by detaining, buffering and attenuating flows. These attributes also provide some level of pollution control by detaining the flow long enough for pollutant removal by physical and/or biochemical processes. They are designed to minimize pollutant discharge so that downstream fisheries, habitat and water quality will be preserved. Because of the direct relationship urban sediment has with pollutants and toxic chemicals, R/D facility design criteria provide control of sediment-laden water and downstream erosion. Control of the 2-year 24 hour duration storm events is needed to provide protection from the cumulative impacts that result in downstream erosion. The need for this protection is supported by recent literature indicating that the level of erosion in a channel is directly proportional to the "work" performed on the channel by flowing water. The dominant flow, defined as channel dominant discharge, is the most effective in performing this "work" and has been found to be in the range of a 1 - 2 year return frequency flow, or an approximate bank-full channel condition. Results of recent studies have demonstrated that substantial removals of pollutants in urban stormwater can be achieved by gravity sedimentation if turbulent mixing can be avoided and the detention time is long. The pollutants most susceptible to removal are Total Suspend Solids (TSS), hydrocarbons, lead, Biological Oxygen Demand (BOD), and total phosphates. Trap efficiencies of 70 percent of TSS, hydrocarbons and lead; 50 percent of BOD and phosphates; and at least 33 percent of chemical Oxygen 0-6 1/90 rX KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Demand (COD), Total Organic Carbon (TOC), and Total Nitrogen (TN) were reported in the studies. TSS is particularly susceptible to removal by sedimentation and can also be representative of the amount of general pollution due to their affinity for absorbing numerous other pollutants. The most important feature for water quality R/D facility design is to promote siltation by providing maximum detention time of the ponded urban runoff. The hydrologic performance concept for R/D design described previously is primarily for controlling downstream erosion and flood events, but its inherent design also provides long detention times and is therefore ideally suited for water quality control. Computer model test cases run by SWM staff for average development conditions resulted in detention times of approximately 30 hours for the 2-year, 24-hour storm. Additional R/D facility design features generally required to promote sedimentation, infiltration, and biofiltration include: o Utilization of long, narrow pond configurations. The minimum required length/width ratio is two; larger ratios are encouraged. o Installation of inlet and outlet structures at extreme ends of the pond. o Flat pond and tank/vault bottoms provide for minimum flow velocity to promote settlement and biofiltration (in ponds). o Provision of water tolerant, stable vegetative ground cover on pond bottom and sides controls erosion and provides biofiltration. o Provision of 6-inch-deep sediment sump (dead storage) over pond and tank/vault bottom area. o Two-cell pond design. Special Water Quality Controls There are two types of special water quality control facilities provided in this Manual to treat surface water runoff. These are wet ponds and vaults, and water quality swales. They are primarily required to treat runoff from developed areas prior to discharge to sensitive natural drainage features such as wetlands, lakes and streams (when not treated by a retention/detention pond), and prior to infiltration. Both of these types of facilities utilize sedimentation, biofiltration and biologic activity as the mechanisms for removal of pollutants from surface water runoff and have been demonstrated to provide substantial water quality improvements by a number of studies. The SWM Division will continue to participate in on-going programs to further substantiate and quantify the benefits these facilities provide, as well as refine the analytic methods and criteria for their design. Vegetation-Lined Swales and Native Growth Areas Vegetation-lined swales (often referred to a grass-lined channels), when properly designed, have been proven effective as "biofiltration" mechanisms for the removal of sediments, heavy metals, and some nutrients from stormwater leaving developed areas. Suspended particles can settle out if the velocity of flow is slowed over an adequate length of channel and, depending on soil type, infiltration will also provide water quality benefits. The optimum design of vegetation-lined swales minimizes water depth and velocity to promote maximum water contact with channel vegetation and infiltration. The preservation of native growth areas is also very important in preserving water quality, as well as environmental features necessary to protect valuable natural resources and maintain stable slopes. Water quality benefits from these native growth areas are both direct and indirect by providing for pollutant reduction or elimination, and provide physical protection of aesthetics and wildlife habitat. For example, natural vegetative corridors along streams or around wetlands provide biofiltration to incoming pollutants and preserve the aquatic and wildlife habitat along the water's edge. O-7 1/90 KING COUNTY, WASHINGTON, SURFACE WATER DESIGN MANUAL Background Discharge of stormwater runoff into surface water can result in water quality degradation of the natural surface water system. For example, the Bellevue National Urban Runoff Program (Pitt and Bissonnette, 1984) stated the following stormwater related impacts to a local stream in an urbanizing area: o Reduction in diversity of aquatic species. o Physiological damage to fish populations o Periodic fish kills associated with dumping of toxic substances into the drainage system o Higher water temperature o Channel instability and increased sediment transport o Increased fecal coliform bacteria populations o Reduced aesthetic value Water quality degradation may be acute or chronic. A fishkill is an acute reaction to dumping of a toxic substance (such as antifreeze) into a catchbasin discharging to a stream. Chronic degradation may also include the gradual accumulation of pollutants (including combustion engine by-products such as cadmium, zinc, and lead) which in turn may contribute to a reduction in the diversity of species and physiological damage to the species that remain. Pollutants in urban runoff are usually attached to sediments. In addition, sediments clog and cement spawning gravels and reduce the capacity of conveyance systems. Control of sediment during all phases of urbanization (construction through full development) is therefore critical to reducing the discharge of pollutants to the County's surface waters. Consequently, the County requires all new development to prepare a plan for the control erosion and sedimentation both during and after construction, (see Requirement #5). In the coming years, there will be growing local state and federal emphasis on the control of water quality. The recently completed 1987 Puget Sound Water Quality Plan, underscores the need for basin planning and controlling the discharge of stormwater pollutants at the source. During the next 5 years the Environmental protection Agency and the State of Washington Department of Ecology will be preparing the requirements for a County-wide permit (under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) program) which will set acceptable levels of stormwater pollutants discharged into the County's surface waters. In response to these programs and King County's own goals for enhancement and preservation of environmental quality, King County will continue to review and update its requirements for the protection of water quality to ensure environmental preservation of our water resources.

Existing Typical Section PROJECT OBJECTIVE The objectives of this project are to relieve traffic pressure on the North Renton neighborhood residential streets and arterials (Park Avenue North, North 3rd Street and North 4th Street) by providing easier ingress/egress for Boeing and PACCAR employees than currently exists. See "Vicinity Map" in the Appendix for project location. I. Project Background This project came out of the "North Renton Street Improvement Recommendations" report dated April 9, 1990. This report was the culmination of studies directed by Council Resolution 2708 in 1988 to assure that arterials providing access to the North Renton area be designed and operated in a manner that is responsive to the needs of the citizens. Between September 1989, and early 1990, the Public Works Department conducted an intensive citizen participation process in North Renton referred to as the North Renton Arterial Facilitation Process. Technical work was done to develop an implementation strategy for the ideas, concerns and suggestions which resulted from the citizen participation process. From this the following project description has been developed for a project that addresses the above objective. II. Project Description A. Existing Conditions The topography where the new roadway runs between North 8th Street and its interchange with Sunset Boulevard is comprised of a wooded slope area and a drainage area (with some evidence of wetlands.) See "Existing Typical Section" for this section of the project in the Appendix. The topography in the Sunset Boulevard interchange area is basically flat with commercial buildings on the east side of Sunset. B. Scope of work This new roadway starts on the north at North 8th Street where it connects with existing Houser Way. From there it runs south between the existing Burlington North Railroad Tracks and 1-405 and terminates by a new interchange connection (to and from the south) with Sunset Boulevard (SR-900). The northbound lane for this interchange will cross under and connect with SR-900 in front of the existing Omar Kyam Restaurant. The southbound lane for this interchange will connect with SR-900 approximately 300 feet south of the I-405 off ramp. The new roadway will have one-lane in each direction with limited access except for access to PACCAR property and near North 8th Street where it will be wider to provide turning lanes. Page 1 Design and construction of this project will be completed in two phases. See "Schematic Concept" in the Appendix. Phase I: 1) Design the full roadway section between North 8th Street and the new interchange connection with Sunset Boulevard and construct the southbound lane only; 2) Design and construct the southbound lane of the interchange connection with Sunset Boulevard; and 3) Design the northbound lane of the Sunset Boulevard interchange connection through the layout plan phase (to determine location and profile of this roadway connection). Phase II: 1) Prepare contract documents and construct the northbound roadway between North 8th Street and the northbound lane of the interchange connection with Sunset Boulevard; and 2) Prepare final design and construct the northbound lane of the Sunset Boulevard interchange connection. C. Design Elements 1. Pavement and building removals; 2. Excavation and embankment (including investigation and removal of unsuitable soils); 3. Roadway base and pavement; 4. Curbs, gutters, sidewalks and curb ramps; 5. Drainage (new and modifications to existing); 6. Street Lighting (new and modifications to existing); 7. Pavement markings, channelization and signing; 8. Landscaping and erosion control; 9. Structural design for the northbound lane undercrossing of SR- 900 and retaining walls; 10. Adjustment and restoration of disturbed property features; 11. Right of Way and easements; and 12. Railroad track crossings. Page 2 D. Special Considerations 1. Wetlands and EIS analysis; 2. Traffic signal needs analysis for North 8th Street and Houser Way intersection; 3. Down stream analysis for drainage; 4. Weaving and merging analysis for the I-405/southbound Sunset off-ramp and the Houser southbound lane at Sunset (a traffic signal may be needed); 5. Construction sequence and traffic control during construction; and 6. Right of Way impact assessment especially along Sunset Boulevard. E. Right-of-Way/Easements a/ ®N ,r- role- 60V-X Right of Way will be needed from private property along Sunset V4 -MN s TZ/W Boulevard, the Burlington Northern Railroad Company and the �..� � 1 ?toes . Washington State Department of Transportation. Construction and slope W&s 7wWMW- 4-AIV easements will also be necessary. 44=w Asw 4r7p1'' F. Environmental Documents. Because of the evidence of some wetlands in the project area, a wetland assessment will be done. The extent of the wetlands will determine the environmental document needs. G. Permits Permits will be required from the Washington State Department of Transportation and possibly the Fisheries Department. H. Value Engineering This project is over one million dollars, therefore, it is recommended that determination of need for value engineering be made. I. Preliminary Cost Estimate The preliminary cost estimate for this project is $4,720,000, which breaks down as follows: Page 3 Phase I Preconstruction Engineering and Administration $ 320,000 Right of Way/Easements and Administration 800,000 Contract Fee 1,227,000 Construction Control and Administration 98,000 Phase I Total $2,445,000 Phase II Preconstruction Engineering and Administration $ 270,000 Right of Way/Easements and Administration 380,000 Contract Fee 1,505,000 Construction Control and Administration 120,000 Phase II Total $2,275,000 J. Funding Sources The funding will come from the following sources: General Governmental Funds $ 221,200 City of Renton E & H Mitigation 540,800 TIA Grant 3,958,000 K. Project Scheduling Phase I Preconstruction Engineering 1st Quarter '91 thru 2nd Quarter '92 Right of Way/Easements 3rd Quarter '91 thru 3rd Quarter '92 Construction 3rd Quarter '92 thru 3rd Quarter '93 Phase II Preconstruction Engineering 1st Quarter '92 thru 1st Quarter '93 Right of Way/Easements 1st Quarter '92 thru 2nd Quarter '93 Construction 2nd Quarter '93 thru 2nd Quarter '94 III. Involvement/Participation A. Community This project will be taken before the community for review and input on three occasions. The first will be an up-front briefing meeting to let the public know we have started the project, introduce the design consultants and inform them of the scope, budget and schedule. The second meeting will be to present the layout plan alternatives for the project. The third and final meeting will be to present the preliminary design plans. Additional meetings with the North Renton Ad Hoc Committee are also anticipated. Page 4 B. Agencies Washington State Department of Transportation will have a design review and approval role because of the need for I-405 right of way. The Burlington Northern Railroad Company will have a role because of the need for their right of way. The Transportation Improvement Board (TIB) will have a design review and approval role because of their funding. C. Private Utilities Puget Power will be involved to supply power for the street lighting. Puget Power as well as other private utilities may be effected by construction at either end of the project. IV. Staffing A. Project Management The Project Manager through design and construction will be Bob Mahn from the Transportation Systems Division of the Planning/Building/ Public Works Department. B.

Sheet 4-11 The consultant has showing some erosion control measures on these sheets. It would probably be more appropriate if the erosion control measures are shown on the demolition plan, since the erosion control measures need to be initially employed during this the demolition phase of the project. The plans should show straw bale check dams in the existing paved ditches which are directly downstream of where construction ends. All catch basin grates (existing and new) in the construction area should be covered with silt fence fabric,if the potential exists for silt laden runoff from the construction site to enter the structures. Sheet 21 Drainage system approved. Sheet 22-24 The existing catch basins and storm pipes which are being modified should have been as- built with the rim and invert elevation determined and shown on the plans. The required rim and invert elevations will need to be determined in a manner so that it will not result in a delay of construction. The Storm Water Utility will expect the matching of existing slopes will be done in a manner which will not result in humps or sags in the storm lines. The entire storm drainage system (existing and new)will need to be as-built upon completion of the project. We assume that the existing and new storm systems located on the hospital property will be maintained by the Hospital, and the portions of these systems located in City right-of-way will be maintained by the City. Any storm system on the Hospital property which will be maintained by the City(if any)will require a maintenance easement. We wonder if your Division accepts 90% compaction in the road section instead of 95% compaction for the removed catch basins and new pipe. The plans presently show 90%compaction. Sheet 25 The existing catch basin which the new 27" storm line is connecting into is a type II 72" catch basin not a type I. Sheet 32 The drainage profiles should show all utility crossings to verify that there is no conflicts between utilities. It is not clear why the plans and specifications sole source RCP while we allow other pipe types as long as there is no capacity reduction and the pipe is structurally adequate for the loading from traffic and/or fill over the pipe (see City of Renton Supplemental Specifications). This could reduce the cost of construction. Sheet 33 The Paved Ditch Detail is ok provided that the consultant has sized the ditch for the 25- year storm, which we are assuming this has been done for this system. The Drainage report for this project contained no information about the size requirements for the new ditches. The plans contain no standard details for erosion control, catch basins(type I, type II, Inlets, ect...), pipe bedding and other structures and storm system appurtenance(see City of Renton Standard Details Manual). We suggest that a standard detail sheet for erosion control and storm drainage be included in the plan set, or in the bid document. Other Utility standard details should also be added if they are not already. Special Provisions Erosion control-sec.8-01.3.4(5) Mulching- Check the rate of mulching application indicated in the specification (..at a rate of 2000 per acre.. 2000 what? lbs?, tons? gallons?). Why is section 8-01.3.(8) being deleted. Why not allow the contractor the option of stabilizing the cut slopes with plastic covering until properly seeded and stabilized. This section does not mention any thing about silt fence and its material specification. Include a specification for silt fence and any other erosion control structure utilized(straw bale check dams,ect.). This concludes our review of the S. 43rd ST. Improvement project. If you have any questions regarding this review please contact me at 277-5547. The normal time frame for plan review is usually two weeks, but we were able to satisfy your time constraint this time and will expect your Division to do the same in the event should our Division request such a urgent review.

All provisions in the Master Agreement remain in effect except as expressly modified by this Task Or- der Authorization,and are incorporated herein by reference. *,"Scope of Task Order No.3 I. DESCRIPTION OF PROPOSED WORK The work under this Task Order consists of a preliminary drainage study for the Houser Way Reloca- tion Improvements project. The work includes hydrologic and hydraulic modeling to verify existing conditions in the vicinity of Houser Way,and analysis of options for conveyance of runoff which drains to and downstream of the Houser Way vicinity. Houser Way Off-Site Regional Drainage Analysis Conduct hydrologic and hydraulic modeling to 1) verify existing conditions in the vicinity of the pro- posed project,and 2) analyze options for conveyance of off-site runoff which drains to the Houser Way vicinity. The analysis will focus on regional drainage conditions as they relate to existing conditions along Houser Way. Hydrologic modeling will build upon previous analyses to obtain better resolution in the vicinity of the project. Hydrographs will be generated for the 2-,10-,25-,and 100-year synthetic King County design storm. Hydrographs will be created using the King County SBUH model,per the King County Surface Water Design(KCSWD)Manual. Hydraulic modeling will rely on the SWMM EXTRAN model which was previously developed by En- tranco. This existing model will be expanded to include the regional drainage system in the vicinity of the proposed project. Hydraulic modeling will be used to evaluate the existing conditions and up to three conveyance alternatives for conformance with the requirements described in Core Requirement No. 4: Conveyance Systems in the KCSWD Manual. The City of Renton will select the conveyance al- ternatives to be examined using the model from those recommended by Entranco. Prepare a brief technical memorandum, summarizing the results of the analyses, and documenting the critical assumptions used for the analyses. Prepare planning level cost estimates based on topographical data provided by the City. 9101!4 22 Exh.&Task or.031Huumr Wy.(413192)/jc 1 of 4 EXHIBIT"B "(cont.)

The project area runs parallel to 1-405 between Sunset Boulevard and Lake Washington Boulevard in Renton, Washington (figure 1). Planned improvements will extend Houser Way through currently vacated right-of-way from North 8th Street south to Sunset Boule- vard, resulting in loss of existing wetland and an open channel. Runoff from developed upland areas is conveyed through the Houser Way area on the valley floor, by way of the open channel or through one of a number of pipes along the hillside, and is eventu- ally discharged to Lake Washington. An existing EXTRAN storm sewer model (a mod- ule of the EPA SWMM model) of the region was refined to provide increased resolution of the project area, and the refined model was used to analyze how the stormwater is conveyed through the existing system. Using the results of the model runs, several op- tions to mitigate the expected changes in the system due to the Houser Way project were evaluated and costs determined for the various alternatives. It is important to note that this analysis focuses on the Houser Way„project as it impacts regional drainage patterns. Project impacts on site drainage, such as in- creased runoff and need for detention, are beyond the scope of this report and would require further analyses. �IZo 4 C k�S MODELING �' G pv" The hydrology of this basin had been characterized as a part of earlier studies (Entranco, 1991). For the Houser Way analysis, two changes were made in the hy- drological calculations in order to gain further refinement for this analysis. First, the drainage basins around Houser Way were further subdivided into several subbasins and the flows for the design storms were calculated for these subbasins. Hydrographs for all basins were found using the King County method, as delineated in the King County Surface Water Design Manua! (1990), using 2, 10, 25 and 100-year 24-hour rain- falls of 2.0, 2.9, 3.4 and 3.9 inches, respectively. The second refinement was to com- bine fewer of the basin hydrographs than had been combined before. Instead, the con- veyance systems were extended to capture flows from individual basins on the hillside to the north and east of the site. The net result of these model improvements is to more accurately mimic the functioning of the systems in the immediate vicinity of Hous- er Way. In previous studies this EXTRAN model had been used to evaluate this area and had been able to reasonably mimic the observations made during the January 9, 1990 storm, a recenV,storm event with a recurrence interval of around 25 years. The model GA-zF c�4 y . AG _ -�r ? 91024.22 Regional Drainage Analysis(614/92) iem 1 y� formulation was improved by the inclusion of information from recent sur✓eys%conduct- ed by Tudor Engineering and SSOE. This information, along with site observations, al- lowed a more detailed model of the existing Houser Way area to be developed. Two assumptions were made concerning the condition of the lower section of the drainage system. At the direction of the City of Renton, the open channels which start south of Lake Washin ton Boulevard and travel through Gene Coulon Memorial Beach Park, hereafter referred to as the pond system, are assumed to be well maintained and free of overgrown bushes. This results in a lower resistance to flow than would occur if the ponds were not maintained. Additionally, the culverts connecting the ponds were assumed o be expanded as planned by the PACCAR project. The added culverts in- clude two 54-inch pipes from the southernmost channel (Pond 1) to the next (Pond 2), and one 84-inch pipe from Pond 2 to Pond 3. These two assumptions are critical to the modeling results, as they increase the conveyance in the pond system which, in turn, increases the conveyance of the entire stormwater system. Predicted flooding leads to another critical assumption regarding the model re- sults. At the uppermost point of the pipe which connects to the North 8th Street storm sewer line from the east, flooding is predicted to occur during high flows. In this ver- sion of the model, this point is called junction 1207 (see figure 2). Due to the formula- tion of the EXTRAN model, the water which floods does not return to the system and is lost. Since the flooding was observed to be significant (over 12 acre-feet for the 25- year storm), an alternate pathway for this water was modeled. Based on topographic information and previous studies (City of Renton, 1988), it was assumed that this water would appear as street flooding until it reached a swale along 1-405, eventually dis- charging into the channel aIong,.thaJJQUW&Way alignment approximately one-third of a mile south.of North 8th Street. Although this assumption is based on precedent and results in a more reasonable simulation than had the loss of stormwater volume been ignored, it must be verified be- fore the final design of any system along Houser Way. It is not certain that this is the path taken by the floodwaters, and it is unlikely that all of the predicted flooding would occur at this point. The pipe systems further up into the basin were modeled in an ef- V� n�ftA' 4fort to check the functioning of the pipe system, and these pipes were found to be over- 0 f! loaded and flooded, decreasing the flow to junction 1207. This may indicate that there p� is some attenuation of high flows within the pipe system in the east basins, and that the o� } actual flows to junction 1207 will be somewhat lower than the modeled flows. The hy- ►'` drograph method used is unable to take into account such attenuation, but the modeled V results can be assumed to represent a worst case scenario. 91024.22 Regional Drainage Analysis(64r92)aem 2 CURRENT CONDITIONS Selected water levels and pipe flows for the existing conditions model runs are shown in table 1. It is important to note that these results are not necessarily compara- ble to observed storm events due to the inclusion of upgrades to the system. In addi- tion to the assumed upgrades to the pond system discussed above, the conveyance through the system is upgraded by the completion of the 72-inch line down Garden Ave- nue. This line greatly increases the flow capacity to the pond system, and the net re- sult of all of the improvements is a lessening of the backwater conditions which have led to street flooding in the past. Table 1 shows the conditions observed for the different modeled storms given the assumed current conditions. The depth of the stormwater in the system, which deter- mines the flooding situation in the area, is shown for two important locations: the PAC- CAR outfall at North 8th and Garden Avenue (junction 1000) and Pond 1 (junction 1001). Additionally, the flows in several important segments of pipe are shown (in cubic feet per second).

Instead of passing larger flows, this pipe would serve to create a restriction on the pipes entering the system at the intersection of North 8th Street and Houser Way, and introduce a backwater situation upstream. The pond sys- tem, on the other hand, does not appear to reach its maximum conveyance even dur- 91024-22 Regional Drainage Analysis(6A,92)aem 3 ey ing the large flow events. However, the increasing levels in the ponds do begin to show backwater effects on the pipes coming in from Garden Street and the North Basin for the larger storms. The EXTRAN model also shows the amount of water which flows out of the system as flooding. Street flooding seems to be relatively unchanged by upsizing the culverts in the pond system relative to the preimproved model runs. The flooding at the Houser / Way underpass is estimated at 0.1, 0.7, 1.4 and 2.5-acr`ei4et for the four design storms. No flooding is predicted along Garden Avenue, where most of the regionals stormwater flows to the pond system. However, the backwater conditions caused by the North 8th Street pipe do lead to a large amount of flooding at North 8th and Houser (1.1, 8.1, 13.9 and 22.7 acre-feet). As noted before, one of the critical assumptions for this modeling was that the overflow waters from the area on the hillside is routed to the cha W, along Houser Way. It is primarily this flow which seems to result in the flood- ing in the vicinity of the intersection. Again, it is not certain how much of this flow is ac- tually attenuated in the systems on the hillside. Any attenuation would probably lead to lower predicted flooding on the valley floor. Ir( P7 A,AJ�! R-�a �- CAA-�f�f'iC `::� 17 vv01.c 60 , In comparison, the 25-year storm for the existing conditions without the larger pond . culverts (but with the assumption of maintained ponds) predicted 1.2 acre-feet of flood- � ing at0derpas"1.7 acre-feet at North 8th Street and Houser Way and 2.8 acre- feet on the hillside, although this run produced 10 percent less flow in the system than the improved condition. The Iow-e -amount of flow is because this run used a different hLdrograph method whi h takes attenuation into account. FOCUS ` , r The directive for this report is to model the existing stormwater system around the Houser Way site and to provide an analysis of possible improvements to stormwater conveyance. The primary focus concerns the changes in regional drainage due to the Houser Way Improvement project. An analysis of the proposed project indicates that on a regional level the effect of the road improvement will be to alter an area along the railroad tracks south of 8th Street, which currently serves as an open channel for storm flows. It is probable that, in order to construct the roadway, this channel will need to be replaced by an underground pipe. The drainage alternatives considered involve con- verting the channel to a pipe and providing some other improvements in the system. 9 1U24-22 Regional Drainage Analyse(N4l92)aem 4 A S�r.E DRAINAGE REQUIREMENTS The City of Renton drainage requirements -are the same as those defined in the King County Surface Water Design Manual. For this study, Core Requirements 1-4 ap- ply. �rl�ft1 4. /A i h 4 P Core Requirement #1 states that runoff "must be discharged at the natural loca- tion". Depending on interpretation, the natural location for discharge from this area could be considered to be at a specific point within the stormwater system, at Pond 1 or at Lake Washington. The intent of this requirement is to ensure that baseflows of streams are not changed by drainage changes, so the flow between pipes within a stormwater system is of lesser concern. Since the entire system from Houser Way to Pond 1 consists of piped storm drains, the natural discharge of this system can be rea- sonably assumed to be considered to be at Pond 1, which is the assumption used for this analysis. Core Requirement #2 calls for an analysis of upstream and downstream areas which would be impacted by the changes to the drainage system. This study would presumably fulfill much of the analysis requirement. The regional analysis does not consider an increase in the amount of runoff gener- ated in the project area, but Core Requirement #3 applies in that the 100-year, 24-hour peak flow after improvement will be constrained to be no more than 0.5 cfs more than the preimproved 100-year flow. Also, some regional biofiltration may be required as part of the improvement project to replace that occurring in the existing channel. The fourth core requirement indicates that new pipe systems are to be designed to convey the 25-year peak flow. The pipes for this study were designed for such a rate, although, as mentioned earlier, those flows will have to be confirmed before final de- sign. OPTIONS AND RESULTS Three alternatives were considered to improve the functioning of the Houser Way drainage system. For all of the runs, the channel along Houser Way is replaced by four 400-foot long sections of 72-inch pipe set at the slope of the existing ground sur- face. This is due to the assumption that the road placement will require filling the chan- nel. One upgrade alternative is to replace the 42-inch pipe under North 8th Street with a 72-inch pipe. A second is similar to this, but also involves removing the cross con- nection between the 54-inch and the 72-inch lines at North 8th Street and Garden Ave- nue. The third alternative is to build a 10-foot wide swale and 48-inch overflow pipe along Houser Way north of 8th Street to divert some of the flows from the North 8th 91024-22 Heyonal Droinaye Analyvs(64i92)aem 5 k.. t Ir Street line and pick up drainage from the hillside. A conceptual drawing of this alterna- tive is shown in figure 3. The swale would have the same surface overflow rate as the existing channel for the 2-year flow, giving it corilparable bipfiltration capacity The results for these alternatives for the 100-year storm are shown in table 2.

Alternative 3 is the bypass swale As shown in table 2, replacement of the channel with a large pipe is not expected to affect the drainage system compared to existing conditions. However, the existing flooding also continues, as well as the existing conveyance, so the replacement cannot be considered to be a drainage improvement. The first alternative, increasing the size of the North 8th Street pipe, leads to in- creased conveyance and reduced flooding throughout the system, eliminating the flood- ing at 8th Street and Houser Way with only a minimal (0.08 acre-feet) amount of flood- ing on Garden Avenue. One major drawback for this option is that it leads to greatly in- creased water levels at the intersection of North 8th Street and Garden Avenue (junc- tion 1000), where drainage from the PACCAR site enters the system. The higher water levels could lead to restricting the flow of water off of that site and result in flooding. In fact, the predicted flooding on the PACCAR site increases from 0.55 acre-feet to 2.0 acre feet due to the enlarged pipe system. 91024-22 Regional Drainage Analysis(6i4l92)aem 6 The second alternative improves on the first alternative by removing the cross- connection between the two Garden Avenue lines at North 8th Street. The result is in- creased conveyance through the Garden Avenue systems (254 cfs vs. 235 cfs, 204 cfs for existing) and down the North 8th Street line while the water level at the PACCAR out- fall is 1.5 feet lower than in alternative one. This alternative does lead to some flooding (0.5 acre-feet) from the North 8th Street line, and the water level at junction 1000 is still 2.15 feet higher than under the existing conditions. However, the predicted increase in flooding on the PACCAR site is only 0.15 acre-feet. The bypass swale alternative, like the first two alternatives, also reduces the pre- dicted flooding at North 8th and Houser Way, although it does not eliminate that flood- ing. Additionally, it results in a slightly improved conveyance down Garden Avenue, but does not affect the maximum flow down the North 8th Street line. Overall conveyance through the system is improved by about 23 cfs, and there is no effect on flooding on the PACCAR site. As mentioned above, the swale would reproduce the ;biofiltration from the existing channel, but there are some uncertainties regarding thip option, in- cluding the size of swale which can be built in the space available. I Coh�4��j These alternatives were run for the 25-year storm as well, and the results are shown in table 3. One of the more important results for this storm is that Alternative 2 does not lead to increased flooding on the PACCAR site for this storm. It is possible that other drainage alternatives may be feasible to achieve the same results, such as replacing one large pipe with two smaller ones, but these were chosen to evaluate options and further design will require more specific information (e.g. sur- vey). A concern about increasing the conveyance through the system is that increases in peak flows will lead to a requirement to provide detention. It is unknown whether the area exists to provide the detention for these alternatives, which would increase the peak flows through the pond system by as much as 82 cfs. The cost for such a facility in this area could be expected to be very significant. COSTS Planning level cost analysis was conducted for the three alternatives. The costs for alternatives 1 and 2 were the same, as the cost of removing the cross connection was assumed to be negligible. Alternatives 1 and 2 were priced out to $1,996,000, and alternative 3 was $2,824,000. These are planning level costs, and are subject to change before final design. Also, there are options which may be as effective at a low- er total cost. The calculations for these costs are shown in Appendix A. 9101a 22 Regional Drainage analysis(b411,11)eem 7 Table 3 Comparison of Houser Way Alternatives Alternatives (25-Year Storm) Existing Pipe Only 1 2 3 Height at junction (ft) PACCAR Ouffall 3.33 3.34 6.95 5.08 3.20 Pond 1 4.31 4.30 4.89 4.98 4.44 Flow in Pipe (cfs) North 8th Street 82.90 82.90 209.00 203.20 82.70 54-inch Garden 47.00 48.90 73.50 62.00 42.00 72-inch Garden 146.80 149.10 169.10 188.90 153.80 North Basin 89.80 90.00 86.00 85.90 89.40 North Houser 20.90 20.90 21.10 21.30 39.60 Pond System 316.70 321.30 391.90 402.20 335.90 Houser Channel 128.80 117.10 117.10 117.10 117.10 Flooding (acre-ft) Houser and 8th St. 13.90 15.60 0.00 0.00 5.40 North Houser 1.40 1.50 1.50 1.50 2.30 PACCAR Site 0.30 0.30 0.50 0.30 0.30 Alternative 1 is the North 8th Street upgrade.

SUMMARY AND CONCLUSIONS There are three alternatives which were evaluated to improve drainage in the vicin- ity of Houser Way. Of these, alternative 2 appears to be superior to alternative 1, as the removal of a cross connection seems to improve drainage in the Garden Avenue li- nes. Alternative 3 does not reduce flooding as much as the other two, but it provides �`'� biofiltration and does not affect the drainage off of the PACCAR site. The costs U the- K.7 first two alternatives is $2,000,000 and the third is $2,820,000. 4. , f RECOMMENDATIONS FOR FURTHER STUDY There are at least two drainage issues regarding the Houser Way Improvement project which will be important to clarify when proceeding with that project. The first is the previously mentioned drainage/overflow off of the hillside, and the resulting flooding on the valley floor, which must be verified before final design. A second issue is the 91024-22 Regional Drainage analyse(614,92)aem 8 fact that a portion of the project area currently drains to a aqypass pipe which runs through the PACCAR site. Since the flow ugh the bypass is limited, peak runoff flow rates may be restricted and additional detention may be required in that part of the site. 91U24-22 Kegional Urainage Analysis(yn'W)ncm 9 Appendix Title Page APPENDIX TITLE LAKE WA5HIN6TON I LEGEND � I 5002 o FIFE \JUNGT I ON ® STOKAGE JUNCTION 500 i 2000 JUNGT ION NLWER 4002 1001 I FIFE/OPEN CHANNEL 3002 4— INFLOW OK 00TFLOW 3001 2002 1904 2001 '�- 1 00 1 1 40 1 1 402 1403 1460 1406 1 1 50 14b 1 1 405 1930 1 450 1451 -�_ I100 1431 1452 1151 1 400 1 432 1 ,433 1 453 I101 I434 II02 160I 1454 '- 1 1 52 1 935 1103 i bO2 193b 1603 r, 11 53 1 1 04 1 437 IIJn\V11 1 604 t 43a 1 1 05 1 605 1 436 1154 11Ob 1606 1711 l 74 I 1792� NOT TO 5GA1.E 1 ► 07 1 607 1106 16045 1710 1740 i l i 09 1609 N p N o 0 p 120 I I Z02 I Z03 - 1 300 I 1 301 750 1 253 135 1dN v i 302 - N v UN o m o do 1252 �--- 11353 1 303 1601 - - - - 309 ►602 1 629 1554 1 700 1 25 1 1 643 1 250 F" v 'IN N _p 1 305 1 603 o c� - , 1 657 1 306 1 604 _ - - 1656 1 730 CEDAR — — — — — —— _ _ 1 645 1605 1859 1 326 1 31 9 I604 1647 1844 160 1 327 1 320 1 407 1 64 1 I N WAv7 ON VALLEY I 1 326 Q N 1 32 1 1 eob dr o - N 18G2 FLOOR D15TI IftJTED 1 8G3 EQUALLY TO JLWT I CNN 0 0 0 o d o IN VICINITY. 1 6L4 F I 61,IRE 2 , 1645 `_)GHEMAT I G OF FIFE SYSTEM t I MODELED WITH EXTUN y � I i 4 O O ♦i. .O�\" 1 •w Oil HOU5E1Z WAY N STREAM BYPASS/OVEM0W PIPE F 1 GUILE 3 .

North Renton Drainage Basin March 22-23, 1993 Stormflows 6 91024-26/Reports/Tm-Mon(6/4/93)/jcw 1 NORTH RENTON MONITORING REPORT INTRODUCTION This memorandum summarizes the findings of the stormflow monitoring study con- ducted by Entranco and the City of Renton during the winter of 1992-93. The goal of this study was to evaluate flow predictions and the hydraulic function of the drainage systems in the North Renton Drainage Basin as it relates to the design of the Houser Way North Improvements Project. The drainage systems have been modeled by Entranco using the Santa Barbara Urban Hydrograph (SBUH) model for flow prediction and the EXTRAN hydraulic model (Entranco 1993). The results of this monitoring study were used to evaluate the modeling assumptions. Recalibration of the models are not a part of this study, but may be undertaken as another phase of the Houser Way North Improvements Project. The most important drainage question regarding the Houser Way North Improvements Project is whether large flows pass through the Houser Way North right-of-way during extreme storm events. Previous modeling analyses predict that the drainage system on the hillside above Houser Way North becomes overloaded at approximately the 10-year storm, resulting in overflow through the Houser Way North right-of-way. Unfortunately, no storm events larger than a 2-year storm occurred during the monitoring period, so this prediction could not be assessed. However, by analyzing the events that did occur, we were able to improve our understanding of the workings of the drainage system. OVERVIEW This stormwater monitoring effort was undertaken as a part of the Houser Way North Improvements Project with the purpose of evaluating the hydrologic and hydraulic model predictions for the drainage system in the area of the project (figure 1). Three types of equipment were used for monitoring: two Isco Type 1870 flow meters, two Stevens Type F water level recorders, and four crest gauges. The Isco meters were located within the manholes at the intersections of North 7th Street/Sunset Way North and North 8th Street/Houser Way North, and provided continuous water levels of the flow through the drainage pipes. The Stevens recorders were located in two open channels: one just south of North 8th Street in the Houser Way North right-of-way and one in the open channel at Gene Coulon Memorial Beach Park. The crest gauges marked the high water levels at the two locations with Isco meters and at two other locations: one at the North 8th Street/Garden Avenue North intersection, and the other at the Houser Way North underpass. 91024-26/Reports/Tm-Mon(6/4193)/jcw 2 Gene Coulon ;:.; ...;:........::. .;:.;:.;;;;;;;;:.;;:.:;>;:.;:;:.;;:.;;:.: Memona d N ; ::>::::::>:�>>>' ' »><':#>>' >`:> :.::.

John Hobson from the City of Renton checked the equipment weekly to record crest gauge levels, change the batteries on the Isco meters, and verify that the mechanical equipment was functioning. One of the Isco meters malfunctioned and was repaired repeatedly, eventually being sent to the factory for maintenance, so there was only one Isco meter functioning from January 14 through March 17. During that time, the functioning Isco meter was located at North 8th Street and Houser Way North. Field observations of two high flow events were made at all locations, one on January 25 and one on March 22. During these storms, flow measurements were taken in the channels where the Stevens recorders were located and in the culverts just upstream of Gene Coulon Memorial Beach Park. Flows and water levels also were inspected throughout the drainage system. The monitoring equipment was removed during the week of April 10, 1993. Rainfall records at SeaTac International Airport indicate that the total rainfall during the monitoring program was lower than average (table 1). Dry weather was encountered during December, January, and February. November rainfall was near normal while March was relatively wet. The largest storm occurred on March 22-23; the total rainfall recorded at SeaTac was 2.07 inches, approximately the same as the rainfall for the 2- year 24-hour storm. Other storms with over one inch of rainfall, as measured at SeaTac, occurred on December 10 (1.33 inches), January 19-20 (1.39 inches), and January 24-25 (1.74 inches). Table 1 Rainfall Comparisons at SeaTac Rain Gauge Rainfall Month 1992-93 Average November 5.6 5.5 December 4.1 6.5 January 4.1 6.2 February 0.4 4.3 March 4.8 3.4 Total 19.0 25.9 Only daily rainfall totals were available from the SeaTac gauge at the time this report was prepared. A second source of rainfall data was King County Surface Water Management. The County maintains a rainfall gauge at approximately 13300 144th Avenue SE in Renton, approximately two miles from the North Renton Basin. Fifteen-minute rainfall totals recorded at this gauge were used to analyze the March 22 storm. The rainfall data allowed us to compare rainfall patterns with the response of the drainage system, and the rainfall/stormwater volumes allowed us to evaluate the land use assumptions used in the 91 024-26/Reports/Tm-Mon(6i4/93)/jcw 4 hydrologic modeling. The total rainfall measured on March 22-23 at the King County gauge was 1.68 inches, which is less than that measured at SeaTac. RESULTS System Function at North 8th Street and Houser Way North One of the major drainage issues in this area is whether or not the system on the hillside overflows during very large storms, and, if so, the route that overflow takes. Unfor- tunately, the mild winter did not provide any storms which would shed light on the over- flow situation. Currently, it is believed that stormflows from 10-year events and larger overflow from the system flow down Sunset Boulevard NE, cross under 1-405, go through the Houser Way North right-of-way and re-enter the storm system near North 8th Street and Houser Way North (figure 1). The flows through the Houser Way North right-of-way were too shallow to measure during non-storm conditions, and even during storm events the peak flow measured was only five cubic feet per second (cfs). This is consistent with the previous modeling which indicated that, until the overflow occurs, the flows through the open channel in the right-of-way are relatively low. In the stormdrain pipe system along North 8th Street, there is a small but steady base- flow through the system, with flows of approximately five cfs flowing throughout the season. During the March 22 storm, flows through the North 8th Street pipe correlate well with rainfall intensities (figure 2), indicating that the timing of the stormflows in the system closely follows rainfall patterns. This confirms the previous modeling results that indicate a similar response. The recorded volume of stormwater through the pipe matches the volume predicted using the hydrologic modeling assumptions or SCS curve numbers (33.4 acre-feet recorded vs. 34.8 acre-feet predicted). By comparing the timing of the peak flows relative to the rainfall patterns, the time of concentration for the area upstream is found to be on the order of 30 to 60 minutes, which again agrees with the previous modeling assumptions. Also, the flow measurements confirm assumptions that the Manning's "n" for the pipes in the Garden Avenue North/Houser Way North vicinity should be 0.017 to take into account all of the entrance and exit losses in the pipes. Based on these observations, the modeling of this part of the system appears to be consistent with the actual conditions monitored. Houser Way North Underpass Houser Way North has experienced serious and recurring flooding at the underpass near Lake Washington Boulevard, so much so that the roadway was closed to traffic during the sampling period. The crest gauge in the manhole at that point indicated that the water level in the storm sewer would often rise, probably due to a backwater effect from the pond system. However, even at its highest point, the water in the manhole was 91024-26/Reports/Tm-Mon(6/4;93)/jcw 5 still over 5.5 feet below the roadway surface. Roadway flooding was observed during the March 22 storm and it was noted that the roadway drains were not conveying stormwater. When the manhole cover in the roadway was removed, water flowed into the drainage system, removing approximately two-thirds of the roadway flooding. From these observations, it is apparent that the frequent roadway flooding at this point can be a local drainage problem, although regional flooding probably occurs here during large storm events. The previous modeling predicted that regional flooding at this intersection would begin with the 2-year design storm, and intensify with larger storms.

As an interim solution, replacing the existing solid manhole cover with a grated cover could remove a significant portion of the flooding. 91024-26/Reports/Tm-Mon(6/4/93)/jcw 6 Ponds According to the Stevens water level recorder in Gene Coulon Memorial Beach Park, there were three events during the monitoring period that generated flows greater than 100 cfs: January 14 (105 cfs), March 14 (104 cfs), and March 22 (118 cfs). The March 22 peak flow is 42 percent less than the 204 cfs predicted peak flow for the 2-year 24- hour design storm previously predicted. This discrepancy is likely to be due to both the lower rainfall total (1.68 inch measured at Renton vs. the 2.1-inch 2-year design storm, a 20 percent difference) and the lower peak rainfall intensities. It is the rainfall intensities, rather than total volumes, that tend to drive peak stormflows. Table 2 demonstrates that the 24-hour design storm is much more intense than the storm on March 22. Table 2 Maximum Rainfall Totals Per Time Span (inches) 2-year, 24-hour March 22, 1993 Time span design storm storm (at Renton) 15 minute 0.15 0.09 30-minute 0.24 0.14 1-hour 0.36 0.20 2-hour 0.52 0.29 6-hour 0.97 0.63 The recorded hydrograph at Gene Coulon Memorial Beach Park for the March 22 event is shown in figure 2. The volume of the stormflow passing through the ponds during this storm was calculated to be 70.6 acre-feet. This is 18 percent less than the 86.2 acre-feet predicted using the measured rainfall and the hydrologic modeling assump- tions (based on SCS curve numbers), indicating that the assumptions used to model the entire basin may be slightly conservative. Flow estimates for the various culverts in the pond system were taken at 8:30 p.m. on March 22. The total flow at that time was 50 cfs and there was approximately 3.5 feet of water in the first pond. Water exited the first pond equally between two 48-inch culverts. Inflows to pond 1 consisted of 20 cfs from the Garden Avenue North 72-inch pipe, 11 cfs from the Garden Avenue North 48-inch pipe, and 19 cfs from the two pipes draining from the north. Of the three 60-inch culverts from pond 3 to pond 4, the middle and the eastern culverts were conveying approximately the same amount of flow while the western culvert was only conveying 15 percent of the total flow (Entranco 1993). Likewise, of the three culverts between ponds 4 and 5, the eastern culvert was conveying only ten percent of the total flow. The culverts with reduced capacity are 91024-26/Reports/Tm-Mon(6/4/90)/jcw 7 clogged with silt and vegetation. These culverts are reducing the conveyance capacity of the pond system and consequently are raising water levels upstream. Previous analyses assumed maintained conditions within the lower pond system (as directed by the City of Renton). The observations made during the current study underscore the need for maintenance to attain maximum flow capacity in the system. The capacities of the pipes entering pond 1 were reduced to some degree by high water levels. Even the 72-inch pipe was affected by backwater, as the pipe was two-thirds full at the outlet, and was only conveying 20 cfs. This confirms the previous modeling which had indicated that the ponds were causing a significant backwater effect on the pipe systems. The backwater effect was probably significantly greater before the recent conveyance upgrades in the pond system. CONCLUSIONS The results of this monitoring study indicate that the previous hydrologic and hydraulic modeling of the North Renton Drainage Basin represents observed conditions reasonably well for small to moderate storm events. The predicted stormflow volumes and routing are consistent with observations, and the fact that the system experiences backwater conditions, even during small storms, was confirmed. Unfortunately, there was no opportunity to confirm how the system functions during large storm events, especially regarding the suspected overflow from the hillside through the Houser Way North right-of-way. Further refinement of the hydrologic and hydraulic models will consist of minor adjustments to the pond system to reflect the effects of siltation in some of the culverts and a full simulation of the March 22-23 storm using recorded rainfall data to compare model predictions with the measurements taken during this study. In addition, further review of the overflow issue will be required including additional field investigations to verify potential overflow routes, and/or increased modeling detail in the immediate vicinity of suspected overflow. These additional model adjustments and analyses will be completed as a part of the Houser Way Roadway Design, which is currently underway.

WLkkb/WJA 1/h.nnin Attachments HOUSER WAY RELOCATION PROJECT DESIGN TEAM MEETING MINUTES OF AUGUST 25, 1993 A design team meeting was held at 10:30 A.M. in the 5TH Floor conference room. The attendees were: Gary Gotti Fire Dept. John Johnson WSDOT Bill File Police Dept. Ginny Hoglund-Gray ENTRANCO Bill Hutsinpiller Park Department Andy Castelle Adolfson John Stein Street Maintenance Gail Roberge Adolfson Allan Johnson Planning & Special Projects Harold Adams Transportation Design Abdoul Gafour Water Utility Joe Armstrong Project Manager Bryson Huie Transportation Operations This was the first meeting of the design team for the Houser Way Relocation project. The purpose of the meeting was to introduce our consultants to the team and to present and discuss the roadway alternatives and the wetland delineation and category classification. Ginny Hoglund-Gray of the prime consulting firm of ENTRANCO was introduced as the project manager. Andy Castelle and Gail Roberge of Adolfson Associates were introduced as the environmental analysts. Ginny presented concept plans and profiles for four(4) Sunset Blvd. connection alternatives and for three (3)N.E. 8th connection alternatives. She went through each alternative discussing the advantages and disadvantages of each alternative. The favored alternative for each end were discussed and supported by the design team. Gary Gotti had concerns with fuel spills related to the many storm outlets that discharge from and above 1405. Harold stated that the storm drainage is a big part of the project and the consultant has identified the storm outlet locations and the regional drainage problems. The drainage design will be determined during the next phase of design and will be presented to the team at our next meeting. Abdoul Gafour asked Gary Gotti if they needed fire hydrants along Houser Way. Gary stated that there would be no requirements for hydrants along Houser Way. Gail Roberge of Adolfson Assoc. presented their findings for the wetland delineation and classification. Gale handed out copies of their rationale for classification and determination along with a map showing location and area(attached). The design team was told how the wetland was delineated and that it fits category 3 classification. The design team supported this finding. Allan Johnson asked if the wetland could be preserved in the preferred alternative. Ginny stated that it would be impossible to shift the alignment over far enough to miss the wetland and provide a buffer. Mitigation measures will be identified in the next design phase and presented to the team at our next meeting. Rationale for Classification of Houser Way Wetlands Adolfson Associates, Inc.

From: Gail Roberge Date: 03/01/94 Subject: Synopsis of meeting with Larry Fisher, WDF As you know, Ralph Nelson and I met with Larry Fisher, Regional Habitat Manager for the Washington Department of Fisheries, on February 23 to discuss the drainage, wetlands, and fisheries protection concepts for the Houser Way project, as a precursor to obtaining an HPA. At the meeting, Ralph and I presented the drainage management concepts: the bioswale, the detention pond, and the created wetlands. Ralph discussed flooding issues and the fact that the project would not increase flows or decrease water quality in Johns Creek at Gene Coulon Park. Larry appeared to be generally satisfied with the fact that (1) the project will not increase flows or degrade water quality in Johns Creek, and may possibly be expected to provide slightly higher water quality in Johns Creek; and (2) drainage will be treated within the bioswale and not piped, as previously planned. Larry also offered the following suggestions for improvements: 1. Check dams should be installed along the bioswale to maximize water/vegetation contact within the Swale. 2. Trees and shrubs should be planted around the wetland and the detention pond to provide shading for temperature control. The concern is that the long, unshaded bioswale would let water temperatures get too high. (Ideally, trees should also be planted along the bioswale for shade, but I was not certain the City would be able to provide this). He expressed concern that if an upgrade to the capacity of the North 8th Street pipe were made, there would be increased water/storm flow into Gene Coulon Park. Since the Houser Way project will not be providing such an upgrade, this is not an issue. I believe that if the above-mentioned suggestions were implemented, and if the drainage management plans remain substantially the same on the HPA application, that Larry would not see a problem with approving the HPA. Once the project is constructed, the City will also be required to obtain an HPA for maintenance of the drainage system (bioswale, detention pond). cc: Joe Armstrong, City of Renton R E C E_ ` _ - Ralph Nelson, ENTRANCO .
