The new floodwall is intended to reduce flood hazards by preventing 80-year floodwaters from entering the ground floor level of the building. The concrete flood control retaining wall would be approximately 4 feet, 4-inches in height and approximately 350 feet in length. The flood wall would extend from the City Library to the Houser Street pedestrian overpass along the south side of the river. The wall would be located 7 feet north of the existing eight-story office building and 32 feet south of the river's ordinary high water mark. The proposal also includes revisions to the existing storm water piping system to prevent surcharge of the river water under the flood control wall in to the building area. The removal of the existing stone wall, sidewalk, benches, two accent lights, and small brick structure would be necessary along the north side of the building. Revision to the existing parking area east of the building, including the removal of the fence surrounding the area, the removal of some asphalt area, and the restriping of the parking stalls, is also proposed. No land clearing or tree cutting is proposed. According to a letter from Northwest Hydraulic Consultants, Inc., dated May 25, 1999, the proposed floodwall would not increase water levels in the Cedar River. A Hydraulic Project Approval was issued for the project December 6, 1999 by the Department of Fish and Wildlife. On August 17, 1999 the Environmental Review Committee issued a Determination of Non-Significance for the project. The proposed site plan for the application was also approved subject to the condition that specified parking areas be revised. A 14-day appeal period commenced on August 23, 1999 and no appeals of the threshold determination or land use decision were filed. All conditions of approval have been satisfied. Construction of the floodwall is anticipated to begin when all necessary permits have been approved. The estimated time frame for the completion of the project would be approximately 60 days LEGAL DESCRIPTION: See attached SEC-TWNP-R: 17-23N-5E WITHIN SHORELINES OF: Cedar River(Urban Designation) APPLICABLE MASTER PROGRAM: City of Renton shsubdev . .

Last August, the project was brought before the Environmental Review Committee and a Determination of Non-Significance was issued. Administrative Site Plan Approval was also given, provided specified modifications to the site plan were made. A two-week appeal period followed the land use decisions and no appeals were filed. As a result of comments made during the ERC meeting for the project, the Parks Division of the Community Services Department requested that the proposed floodwall be designed so that access through the wall was available for future maintenance. During the time that has lapsed since the issuance of the land use decisions, the Community Services Department investigated the feasibility of such a design, including associated costs and structural modifications. As indicated in a memo received from Leslie Betlach, Parks Director(located in attached file), last week the Department determined that the gate access way was not necessary or desirable at this time. Subsequently, a revised site plan was submitted. All conditions of approval have been satisfied and it is now appropriate to issue the Shoreline Permit for the project.

Regards, Le y Lesley Nishihira -City Hall Flood Wall.doc Page 1 CITY OF RENTON iaLL Community Services MEMORANDUM Date: March 24, 2000 To: Lesley Nishihira, Assistant Planner From: Leslie Betlach, Parks Director Re: Historic City Hall Flood Wall I have reviewed the recommendation from Inca Engineers regarding potential modifications to the City Hall Flood Wall in order to allow for the installation of a gate. Based on Inca's analysis, the Parks Department agrees with the recommendation that the installation of a gate, or making modifications to the wall to allow for the future installation of a gate are not necessary or desirable at this time. This decision is attributed to several reasons including but not limited to: cost, significant structural modifications in order to maintain stability, and lack of knowledge at this time regarding potential access requirements and the type of gate that would be best suited for this location. Constructing the wall continuously, at this time, is not only the most economical but makes the most sense. If and when a future need arises for a gate, sawcutting of the wall along with some minor demolition will not adversely impact the existing wall. We will have better knowledge, based on experience, on whether we need a gate and what type would best meet the City's needs.

REPORT AND DECISION OF AUGUST 17, 1999 Page 2 of 7 PART ONE: PROJECT DESCRIPTION/BACKGROUND The proposal is to construct a new flood wall adjacent to the old City Hall building on the south side of the Cedar River. The new flood wall is proposed in order to prevent 80-year flood waters from entering the ground floor level of the building. The concrete flood control retaining wall would be approximately 4 feet, 4-inches in height and approximately 350 feet in length. The flood wall would extend from the City Library to the Houser Street pedestrian overpass along the south side of the river. The wall would be located 7 feet north of the existing eight story office building and 32 feet south of the river's ordinary high water mark. The subject site is relatively flat and is fully developed with a combination of building, landscaping, and asphalt parking. The site is externally drained by an underground storm water drainage system directed to the Cedar River. The proposal also includes revisions to the existing storm water piping system to prevent surcharge of the river water under the flood control wall in to the building area. The removal of the existing stone wall, sidewalk, benches, two accent lights, and small brick structure would be necessary along the north side of the building. Revision to the existing parking area east of the building, including the removal of the fence surrounding the area, the removal of some asphalt area, and the restriping of the parking stalls, is also proposed. No land clearing or tree cutting is proposed. In addition, a new concrete walkway would be constructed between the flood wall and the building as well as a new 5-inch high wheel stop curb on the north side of the parking area. Views of the Cedar River from the parking lot and west patio would be blocked by the proposed flood wall. As proposed, access from the south side of the river would also be eliminated. The proposal requires Environmental (SEPA) Review, Administrative Site Plan Approval, and a Shoreline Substantial Development Permit. Construction of the flood wall is anticipated to begin immediately after all permits have been issued. The estimated time frame for the completion of the project would be approximately 60 days. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21 C.240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: (1) Earth Impacts: The site is presently developed with an existing eight story office building formally used as the Renton's City Hall. The site includes associated parking areas, landscaping, and improvements. The majority of the site is flat with a gentle slope between two levels on the east side of the building. An existing rockery divides the two levels on the west and south sides of the building. On site soils consist primarily of compact brown sandy gravel with layers of silty sandy gravel. The project would require the excavation of approximately 500 cubic yards of earthwork for the construction of the new flood control wall. Approximately 50 cubic yards of the excavated materials would be hauled off-site, while the remainder would be reused as backfill after the flood wall is constructed. In addition, the removal of the existing stone wall, siteerc City of Renton P/B/PW Department ininistrative Site Plan Approval&Environmer 'eview Committee Staff Report OLD CITY HALL FLOOD CONTROL WALL LUA-99-100,SA-A, ECF, SM REPORT AND DECISION OF AUGUST 17, 1999 Page 3 of 7 sidewalk, and some areas of asphalt, would be necessary along the north and east side of the building. Benches, accent lights, and a small brick structure would also be removed. The existing ground elevations would not be altered. The project would not require the removal of any existing landscaping. In order to control potential erosion and sedimentation impacts to the river, proposed erosion control measures include the installation of 18-inch filter fences along the area of excavation and along the river side of the work. Existing storm drains would also be surrounded with filter fabric and straw bails. In order to further reduce erosion in potential flooding, sod would be installed over the excavated soil on the river side of the flood wall. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A (2) Water/Shoreline Impacts: The proposal would involve construction work within 32 feet of the high mark of the Cedar River. The Cedar River is regulated by the City's Shoreline Master Program which requires a Shoreline Substantial Development Permit for any non-exempt work within 200 feet of the ordinary high water mark of the river. The Cedar River is also a known spawning area for Puget Sound Chinook Salmon. At this portion of the river, the shoreline consists of sandy gravel soil, natural rock, rock rip rap, and rock gabions. The ground level at the new flood control wall is approximately six feet above the river at the high water line. A letter submitted by Northwest Hydraulic Consultants, Inc., dated May 25, 1999 indicates that the proposed flood wall would not increase flood levels in the Cedar River. No work is proposed to take place in the river. Currently, the site is externally drained by an underground storm water drainage system directed to the Cedar River. The removal and replacement of the concrete walkway along the north side of the building would decrease the total amount of impervious surface on the site. In addition, the existing storm lines would be revised to prevent back flow of flood waters under the new flood control wall. Specifically, one way flap valves would be installed on the ends of two existing storm lines located at the water's edge. Manholes would also be installed on the dry side of the flood wall in order to allow pumping out of accumulated surface water when the flap valves are activated. One storm water line leading up to the river would be abandoned and sealed off. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A B. Recommendation Based on analysis of probable impacts from the proposal, staff recommend that the Responsible Officials make the following Environmental Determination: DETERMINATION OF DETERMINATION OF XX NON-SIGNIFICANCE NON- SIGNIFICANCE-MITIGATED. Issue DNS with 14 day Appeal Period. Issue DNS-M with 15 day Comment and A eal Period. Issue DNS-M with 15 day Comment Period with a Concurrent 14 day Appeal Period. C. Mitigation Measures The analysis of the proposal does not reveal any impacts requiring mitigation above and beyond existing code provisions. siteerc City,of Renton P/B/PW Department iinistrative Site Plan Approval&Environmen ?view Committee Staff Report OLD CITY HALL FLOOD CONTROL WALL LUA-99-100, SA-A, ECF, SM • REPORT AND DECISION OF AUGUST 17, 1999 Page 4 of 7 Advisory Notes to Applicant: The following notes are supplemental information provided in conjunction with the environmental determination.

Consistency with Site Plan Criteria In reviewing the proposal with respect to the site Plan Approval Criteria set forth in Section 4-31- 33(D) of the Site Plan Ordinance, the following issues have been identified by City Departmental Reviewers and Divisional Reviewers: 1. Conformance with the comprehensive plan, its elements and policies; The subject site is designated Center Downtown on the City's Comprehensive Land Use Map. The proposal would allow for the construction of a flood protection wall. The proposal is consistent with the following policies contained with the Environmental Element: Policy EN-19. Limit development within the 100 year floodplain to that which is not harmed by flooding. Roads and finished floors of structures should be located above the 100 year flood level and new development should provide compensation for existing flood storage capacity due to filling. Policy EN-20. Restrict land uses to those which do not cause backwater or significantly increase the velocity of floodwaters. siteerc City;or Renton P/B/PW Department ginistrative Site Plan Approval&Environmen ?view Committee Staff Report . OLD CITY HALL FLOOD CONTROL WALL LUA-99-100, SA-A, ECF, SM REPORT AND DECISION OF AUGUST 17, 1999 Page 5 of 7 2. Conformance with existing land use regulations; The subject site is designated Center Downtown (CD) on the City's Zoning Map. The proposed flood wall does not fall under the uses regulated by the provisions of the CD zone. 3. Mitigation of impacts to surrounding properties and uses; The proposal would help to reduce flooding impacts to properties south of the proposed flood wall in the event of the 80-year flood event. The concrete flood control wall increase the flood levels in the Cedar River and is not anticipated to create adverse impacts to surrounding properties and uses. 4. Mitigation of impacts of the proposed site plan to the site; The project would take place within 32 feet of the ordinary high water mark of the south side of the Cedar River. In order to control potential erosion and sedimentation impacts to the river, proposed erosion control measures include the installation of 18-inch filter fences along the area of excavation and along the river side of the work. Existing storm drains would also be surrounded with filter fabric and straw bails. In order to further reduce erosion in potential flooding, sod would be installed over the excavated soil on the river side of the flood wall. 5. Conservation of area-wide property values; The proposal is anticipated to conserve area wide property values. 6. Safety and efficiency of vehicle and pedestrian circulation; The proposal includes the removal and replacement of the existing concrete pedestrian walkway located north of the existing building. There are 184 parking stalls provided on or adjacent to the subject site. The proposal would also revise 20 parking stalls located to the east of the office building from standard stall dimensions to compact stall dimensions. No existing spaces would be displaced as a result of the proposal. The proposal would not change the use of the site, nor create areas requiring the need for additional parking. Therefore, the proposal would not be subject to the requirements of the parking regulations. However, the revised stalls would need to satisfy all required stall dimensions and back out distances. The revised compact stalls comply with the required minimum stall width of 8%2 feet and aisle width of 24 feet. However, the proposed lengths of the 12 stalls located on the north side of the parking area are shown with a 4-foot overhang. Although the parking regulations allow the reduction of stall lengths when overhang is provided, only a 2-foot reduction is permitted. The proposed lengths for these 12 stalls are less than the permitted reduction. Prior to the issuance of building permits, the site plan would need to be revised to indicate the appropriate lengths for the 12 compact stalls on the north side of the parking area. This may require revisions to the drive aisle and stall sizes for the row of spaces on the opposite side of the parking area. 7. Provision of adequate light and air; This criteria is not applicable to the proposed flood wall. 7. Mitigation of noise, odors and other harmful or unhealthy conditions; The proposal is not expected to create any harmful or unhealthy conditions. Noise, dust, and odors, which may result from the temporary construction on the site, would be mitigated by the applicant's construction mitigation plan. 8. Availability of public services and facilities to accommodate the proposed use; and Utilities and roads adequately serve the subject site. The proposal would not require the extension of services or further improvements. As part of the proposal, the existing storm lines would be revised to prevent back flow of flood waters under the new flood control wall. siteerc Cite of Renton P/B/PW Department linistrative Site Plan Approval& Environmen view Committee Staff Report OLD CITY HALL FLOOD CONTROL WALL LUA-99-100, SA-A, ECF, SM REPORT AND DECISION OF AUGUST 17, 1999 Page 6 of 7 10.

The only soil data provided was a boring log provided on the original construction documents of the City Hall building dated 1966. Soil design parameters can be obtained through the reference of tables and figures provided in a couple of sources. The sources referenced for this project were the 1997 UBC, Volume 2 and Braja Das, 1995. Because this structure is designed for the event of a flood it is assumed that the soils will be saturated. Because the design event is infrequent the probability of flood and seismic events occurring simultaneously is very low and, therefore, not designed for concurrent events. A spreadsheet was developed to assist in the design of this structure for stability against overturning and sliding, and to check bearing pressure against its capacity. The ENERCALC program was used as an independent check on the design. This software has many design features including the design of cantilevered retaining walls. However, this feature of the program is designed for retaining earth. Therefore, the input has been slightly modified for the detainment of water.

OLD CITY HALL 200 MILL AVENUE SOUTH EXHIBIT " A " COMMUNITY SERVICES ADMINISTRATION JIM PAXTON, CIP COORDINATOR PROJECT NARRATIVE DevEto pmEtoRENTON JO 2 1999 OLD CITY HALL FLOOD CONTROL WALL RECEIVED PROJECT NAME, SIZE AND ZONING The project is designated as the Old City Hall Flood Control Retaining Wall, 350 feet long, in an area zoned CD (commercial district)with CA(commercial arterial ) zoned property on the north, CD (commercial district) zoned on the west and R-8 (residential 8 du/acre ) zoned property on the east located on the other side of the 1-405 Interstate. This overall site is located in the north end of the Renton business district and is surrounded by Houser Way, Mill Avenue, Bronson Way, and the Cedar River.. CURRENT USE OF THE SITE The current use of the site is for the Municipal Court Building and the detention services of the Renton Police Department within the Old City Hall Building.There are no known improvements planned to the site or buildings, except to remove the Municipal Court Building under another contract. SITE FEATURES The site is flat, fully developed, and generally has two levels with a gentle slope between levels along the east side of the building and a rockery wall between levels on the west&south sides. The Cedar River is located along the north edge of the property and in the general vicinity of the new flood control wall. SOIL TYPE AND DRAINAGE CONDITIONS The site is covered by a combination of buildings, landscaping and asphalt parking. It is externally drained by an underground storm water drainage system directed to the Cedar River. The soil type is primarily a very compact brown sandy gravel with layers of silty sandy gravel. SCOPE OF PROPERTY AND BUILDINGS The general use and scope of the Old City Hall Property (excluding the Library Building And Library Parking Lot) is as follows: Municipal Court Building -two stories high 4,800 SF (to be removed ) The Old City Hall Building -eight stories high 54,950 SF Total Building Footprint Coverage 14,164 SF Landscaping Area ..48,375 SF Total Parking Including Off-Site Lot 184 stalls Percentage of Site Covered by Buildings -10% Percentage of Site Covered by Landscaping - 32% Percentage of Site Covered by Asphalt -58% Total Site Area excluding Library - 150,000 SF Vehicular Access to the Site is available from Houser Way, Bronson Way and Mill Avenue South PROPOSED OFF-SITE IMPROVEMENTS None TOTAL ESTIMATED CONSTRUCTION COST The present estimated construction cost of the Concrete Flood Control Wall is $ 150,000 including hard and soft costs. The fair market value of the wall is unknown. MATERIALS AND QUANTITIES The new flood control wall will consist of one foot thick plain-faced reinforced concrete. The ground excavation for the wall will include approximately 500 CY, most of which will remain on-site and be used for backfill after the concrete wall is constructed. The existing ground elevations will be left as-is. LANDSCAPING The present landscaping,trees, shrubs, and ground cover, will remain. New sod will be installed over the excavation on the river side of the flood control wall to reduce erosion. LAND DEDICATED TO THE CITY None ADJACENT WATER AREA Cedar River NATURE OF SHORELINE The shoreline of the river along the flood control wall consists of sandy gravel soil, natural rock, rock rip rap, and continuous rock gabbions. The ground level at the new flood control wall is approximately six feet above the river at the high water line. PROJECT USE AND VARIANCE REQUESTS It is anticipated that this Flood Control Wall Project will need to solicit the following agencies for the specific permits listed: JARPA PERMIT—Hydraulic Project Approval from the Department of Fish and Wildlife SHORELINE SUBSTANTIAL DEVELOPMENT PERMIT—from the City of Renton ADMINISTRATIVE SITE PLAN APPROVAL—from the City of Renton PUBLIC WORKS CONSTRUCTION PERMIT—from the City of Renton PUBLIC WORKS CONSTRUCTION PERMIT—from the City of Renton BUILDING PERMIT—from the City of Renton SEPA EXEMPTION —with a Threshold of Determination of Non-Significance from the City of Renton • CONSTRUCTION MITIGATION DESCRIPTION OLD CITY HALL FLOOD CONTROL WALL Construction Dates It is desirable to commence construction of the flood control wall as soon as possible in order to protect the Old City Hall Building from further floods. Construction is expected to commence immediately after all permits are obtained, however, the number of required permits are numerous and a specific time table for construction is difficult to estimate at this time.

Suite 400 Bellevue, WA 98004 City of Renton Flood Retaining Wall Along the Cedar River DESIGN NOTES Soil design parameters, usually provided by a geotechnical consultant, were available. The only soil data provided was a boring log provided on the original construction documents of the City Hall building dated 1966. Soil design parameters can be obtained through the reference of tables and figures provided in a couple of sources. The sources referenced for this project were the 1997 UBC, Volume 2 and Braja Das, 1995. Because this structure is designed for the event of a flood it is assumed that the soils will be saturated. Because the design event is infrequent the probability of flood and seismic events occurring simultaneously is very low and, therefore, not designed for concurrent events. A spreadsheet was developed to assist in the design of this structure for stability against overturning and sliding, and to check bearing pressure against its capacity. The ENERCALC program was used as an independent check on the design. This software has many design features including the design of cantilevered retaining walls. However, this feature of the program is designed for retaining earth. Therefore, the input has been slightly modified for the detainment of water.

DESCRIBE THE CURRENT USE OF THE PROPERTY,AND STRUCTURES EXISTING ON THE PROPERTY. IF ANY PORTION OF THE PROPOSED ACTIVITY IS ALREADY COMPLETED ON THIS PROPERTY,INDICATE MONTH AND YEAR OF COMPLETION. An existing eight-story former City Hall Office Building and existing large parking lot compose the primary utilization of the site upon which the flood control wall is being proposed. The building was constructed in 1967 and has been used as a City Hall until 1998. Portions of the building are still being used for the Municipal Jail and Police Department. In the future, the City is planning to utilize the building as general office space. IS THE PROPERTY AGRICULTURAL LAND?❑YES❑NO ARE YOU A USDA PROGRAM PARTICIPANT? ❑YES❑NO 7a DESCRIBE THE PROPOSED WORK COMPLETE PLANS AND SPECIFICATIONS SHOULD BE PROVIDED FOR ALL WORK WATERWARD OF THE ORDINARY HIGH WATER MARK OR The flood control wall will be constructed of reinforced concrete with a cantilevered concrete footing system below ground and a plain rusticated concrete surface above ground. The wall will be exposed approximately four to five feet above the existing ground level and extend along the north side of the Old City Hall site adjacent to the Cedar River bank for a distance of approximately 375 feet. The construction work will occur at a minimum of 25 feet away from the edge of the river and approximately 7 feet away from the exterior wall of the Old City Hall building.. Two existing storm water pipes extending under the proposed flood control wall will have one-way flapper valves installed on the ends of the pipe and two storm water manholes will be installed on the building side of the wall to allow pumping out of surface water behind the flood wall, when necessary. The existing trees, shrubs, and ground cover will be left in place with the addition of sod over the temporarily excavated area adjacent to the flood control wall on the river side of the wall to reduce erosion during flooding. Portions of existing sidewalk and asphalt pavement will be removed and some reinstalled after the concrete flood wall is constructed. There will be approximately 1,380 square feet less impervious surface than presently exists. lb.DESCRIBE THE PURPOSE OF THE PROPOSED WORK The ground floor level of the eight story building is subject to flooding approximately 3 feet high inside the building from the Cedar River during high water flooding conditions. During floods, City personnel install sand- bags on top and beyond the sides of an existing short rock "flood wall" located adjacent to the Old City Hall Building. The flood waters have never been allowed to go beyond this wall and inundate the building. This project is to construct a higher and permanent flood control wall so temporary flood control measures will not be required on a continuing basis. 7c. DESCRIBE THE POTENTIAL IMPACTS TO CHARACTERISTIC USES OF THE WATER BODY. THESE USES MAY INCLUDE FISH AND AQUATIC LIFE,WATER QUALITY,WATER SUPPLY,RECREATION,and AESTHETICS. IDENTIFY PROPOSED ACTIONS TO AVOID,MINIMIZE,AND MITIGATE DETRIMENTAL IMPACTS,AND PROVIDE PROPER PROTECTION Since the construction work is located away from the river, there are no changes to the use of the river, river flow, aquatic life, water quality, water supply, etc. There is no effect on the use of the river for recreation purposes or aesthetics except visual and physical access to the river will be reduced by the presence of the wall in this area. A temporary filter fence will be installed along the entire length of the new wall and between the wall and the river while the work is being done. Bales of straw and filter fabric will also be temporarily installed at each catch basin to prevent sedimentation from entering the storm water system.

TO: Pre-Application File No. 99-77 FROM: Jennifer Toth Henning SUBJECT: Old City Hall Flood Wall Pre-Application Comments General. We have completed a preliminary review of the pre-application materials for the above- referenced development proposal. The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision makers (e.g., Hearing Examiner, Zoning Administrator, Board of Adjustment, Board of Public Works, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. As we understand the project proposal,the City of Renton intends to install a concrete flood control retaining wall on the north side of the Old City Hall Building (200 Mill Avenue South). The flood control wall would be approximately 4-feet 3-inches in height and extend approximately 400 feet in length. The proposed wall would be located 10 feet north of the former City Hall structure and approximately 29 feet south of the High Water Line. The proposal would also include revisions to the existing storm water system to prevent surcharge of the flooding river water under the flood control wall into the building area. Zoning. The project site is located in the Center Downtown(CD)Zoning designation. Site Plan Review. Development proposals in the CD Zone are subject to Site Plan Review unless exempt from environmental review, or, unless a conditional use permit is needed. The flood wall proposal is not exempt from environmental review and does not require a conditional use permit, therefore the applicant will need to apply for administrative site plan approval. Site plan review would be processed concurrently with environmental review. Environmental Review. The project to reconstruct a shoreline protection structure is subject to environmental review(SEPA). A completed environmental checklist is required to be submitted with the project application. The checklist and narrative should discuss the proposal and disclose any potential impacts to the environment. The application will need to clearly state that the work is being done within 200 feet of the Ordinary High Water Line(OHWL) of the Cedar River, and show the location of the OHWL on the site plan. In addition, you should discuss the schedule for completing \\TS SERVER\SYS2\COMMON\H:\DIVISION.S\DEVELOP.SER\DEV&PLAN.INGVTH\PRE-APPS\FLDWL.DOC April 7, 1999 Page 2 the work, and provide an estimate of the quantity of material to be excavated(cut) and filled (in cubic yards). Erosion control, sedimentation control, impacts to vegetation and wildlife, construction schedule will all need to be discussed. Land Clearing and Tree Cutting Regulations. If the proposal would require the removal of vegetation or the cutting of trees within 25 feet of the ordinary high water mark for the Cedar River, then the applicant would need to apply for a Variance from the Land Clearing and Tree Cutting Regulations. Special consideration should be given to the existing ornamental cherry trees during construction, in order to protect the trees and root structure from damage. Flood Hazard Regulations. A review of the flood hazard regulations indicates that a development permit is required before construction of development begins within any area of special flood hazard. Such development permits include: site plan approval, shoreline substantial development permit, construction permit, and building permit. According to Code Section 4-3-060:E.1 specific information is required to be included on the permit application including a description of the extent to which a watercourse will be altered or relocated as a result of proposed development. Shoreline Substantial Development Permit. The proposal is subject to a Shoreline Substantial Development Permit since the proposal is within 200 feet of the Ordinary High Water Mark of the Cedar River, since the project is considered replacement and not repair, and since the fair market value of the work would exceed$10,000. It does not appear that the project would trigger the need for variances. Once the environmental review is complete and the appeal period has ended,the Shoreline Substantial Development Permit could be issued by the City and sent on to the Department of Ecology. DOE administers a 21-day appeal period. Department of Fish and Wildlife. Before submitting for permits, you should contact the Washington Department of Fish and Wildlife to discuss any permitting issues they may have. WDFW will probably require Hydraulic Permit Approval (HPA). The proposed construction will likely be conditioned to occur during a specific seasonal construction window as established by the State of Washington for fish-bearing waters. Section 7 Consultation with Army Corps of Engineers. If any federal funds will be expended on the proposal,the project may require permits from the U.S. Army Corps of Engineers (USACOE). Consultation with National Marine Fisheries (NMFS)could also be required due to the recent listing th of the Chinook Salmon as an endangered species. Development Services Division staff(project manager) should attend these meetings also. o 2 Coastal Zone Management Certification. Projects conducted that are either authorized by the US 2 r Army Corps of Engineers and/or require federal permits or funding, require Coastal Zone Management Certification from the federal permitting agency or Ecology Headquarters, Coastal Zone 2 N Management Program. cc: Jana Hanson northwest hydraulic consultants inc. sacramento 16300 christensen road,suite 350 vancouver seattle,washington 98188-3418 edmonton (206)241-6000-phone (206)439-2420-fax seattle May 25, 1999 4 Jim Paxton, CIP Coordinator J O TA City of Renton Community Services Eiji Fti1-4x/N,y� Renton City Hall — 5th Floor ��C �y �99 NQ Renton, WA 98055 , 9 Dear Mr. Paxton: RE: Old City Hall Flood Wall and Renton Library Northwest Hydraulic Consultants (nhc) has completed its analysis of proposed projects along the Cedar River between Houser and Bronson Way, namely a proposed flood wall to protect the old Renton City Hall building and proposed revetment along the channel banks under the City of Renton Library. As will be described in the following paragraphs, our study shows that neither project will be expected to increase flood levels in the Cedar River. Proposed Projects The Old City Hall building(also known as the Renton Municipal Building) is located along the Cedar River about 25 ft away from the south bank,just downstream of Houser Way and just upstream of the Renton Library. The bottom floor of the building is on ground which is about 10 ft lower than most of the surrounding overbank floodplain. As a result it lies within the present 100-year floodplain and is potentially subject to flooding, although sandbagging efforts have prevented flood damages during the most recent high flows on the Cedar River. The City is proposing to build a flood wall along the south bank of the river to provide between approximately 80-year and 100-year flood protection for the building. The flood wall would extend approximately from the footbridge at the downstream side of Houser Way to the upstream side of the library, and would be offset from the top bank of the Cedar River by about 18 ft (or about 7 ft away from the building). The location of the building with respect to the river and the proposed location and alignment of the flood wall are depicted in Figure 1. The City of Renton Library is situated "over" the Cedar River,just downstream from Old City Hall and upstream from Bronson Way. It is supported by piers which lie within the main channel of the river. The City is concerned about erosion along both banks of the river under the building, which has exposed the building supports at the tops of the banks and may threaten to undermine the foundations. Rock gabion baskets presently exist along the toe and lower slope of the south bank, while the north bank slope is unprotected. Additional riprap revetment is being proposed along both banks of the Cedar River beneath the Library. Plan and cross-sectional views of the proposed revetment is given in Figure 2. RIVER ENGINEERING / HYDRAULIC MODEL TESTING / HYDRAULIC ANALYSIS AND DESIGN / COASTAL ENGINEERING HYDROI OGY / SEDIMENTATION ENGINEERING / NUMERICAL MODELING / APPLIED RESEARCH / FORENSIC ENGINEERING Jim Paxton, City of Renton 2 May 25, 1999 nhc was retained by the City of Renton to perform an hydraulic analysis to estimate the potential impacts on Cedar River water levels due to the proposed flood wall, and to comment on the any potential hydraulic impacts due to the library revetment project. Hydraulic Analysis An existing HEC-RAS backwater profile computer model exists of the Cedar River through the City of Renton. The model was recently updated with cross-sections surveyed in October 1998 by nhc. For the study of the proposed flood wall, the model was refined in the vicinity of the Old City Hall by the addition of new cross-sections. Overbank portions of the new cross-sections were taken from recent contour mapping which was provided by the city, while the in-channel portions were interpolated from the existing surveyed sections. Figure 1 shows the location and extent of all the model cross-sections in the vicinity of the project. Two hydrologic flow conditions were examined: the most recent estimate of the 100-year peak flow discharge (made by the U.S. Army Corps of Engineers), and the estimated peak discharge of the November 1990 flood event (considered approximately an 80-year flood event). The two events have instantaneous peak discharges of 12,000 cfs (cubic feet per second) and 10,600 cfs, respectively. For both events, the refined model was used to create flood profiles for the existing baseline condition (i.e. no flood wall). Under existing conditions, the low overbank floodplain areas immediately upstream and downstream of the bottom floor of the building would flood; however, the majority of these areas are ineffective in terms of conveying flood water. The police parking lot on the upstream side is ineffective because it is confined between Houser Way and the Old City Hall building. Furthermore, an existing fence along the approximate alignment of the proposed flood wall effectively cuts off this area from actually conveying flood water (although it still floods). The low area just downstream from Old City Hall is ineffective because it is confined between the building and the library parking lot (see Figure 1). For the purposes of simulating existing conditions, it was conservatively assumed the fence was not present and that a small amount of these areas just upstream and downstream of the building would convey flow. This was defined in the HEC-RAS model using ineffective flow limits, based upon a 3:1 expansion of flow and a 1:1 contraction of flow. The Old City Hall building itself was blocked out of the model cross-sections using the blocked obstruction feature. Cross-section plots for the existing condition model are shown in Figure 3. The model was then modified to add the proposed flood wall at each appropriate cross-section, then flood profiles were created for both hydrologic conditions. The flood wall was considered in HEC-RAS to be a levee, which confines flow to the main channel side of the flood wall (levee) and prevents any flow from reaching the Old City Hall building or its adjacent overbank. Cross-section plots for the model with the flood wall in place are shown in Figure 4. Results For each flow condition, 12,000 cfs and 10,600 cfs, the results of the existing condition (no flood wall)were compared to the results of the proposed condition (with the flood wall). This reveals that northwest hydraulic consultants inc. Jim Paxton, City of Renton 3 May 25, 1999 there would be no increases in the water levels of the Cedar River due to the proposed flood wall. In fact the water surface profiles drop slightly with the flood wall in place, as shown in Figure 5. This is because the channel becomes slightly more hydraulically efficient with the flood wall, as there are less transition (contraction or expansion of flow) energy losses. Table 1 presents in tabular form the results of the HEC-RAS model for each modeled condition. This table shows that at all cross-section locations, the computed water surface elevations with the flood wall are at or slightly below the existing condition water surface elevation. The HEC-RAS model, and all its input and output(including Table 1), are based upon the NGVD 1929 vertical datum. The predicted water surface elevations with the flood wall in place are summarized below, given for both the NGVD 1929 datum and the more recent NAVD 1988 datum (assuming a 3.6 ft datum shift). These could be used to set the minimum elevation of the top of the flood wall, assuming no freeboard. Just above Library, section 80.40 Just below Houser Way, section 84.01 (Downstream end of Flood Wall) (Upstream end of Flood Wall) 12,000 cfs: 37.5 ft (NGVD 1929) 37.8 ft (NGVD 1929) (100-year) 41.1 ft (NAVD 1988) 41.4 ft (NAVD 1988) 10,600 cfs: 36.2 ft (NGVD 1929) 36.5 ft (NGVD 1929) (80-yr) 39.8 ft (NAVD 1988) 40.1 ft (NAVD 1988) The model results also predict that for the 100-year flood, given the present channel conditions in the HEC-RAS model, water levels at the upstream end of the Renton Library (cross-section 80.03) do not reach the bottoms of the floor beams of the building. However, the water levels at this location come very close to reaching the bottoms of the structural beams, given the elevations shown on Figure 2. Library Revetment It is our opinion, based upon review of the planned revetment beneath the Renton Library (Figure 2), that there would not be any significant water level or other hydraulic impacts due to the riprap revetment as proposed. On the south bank slope, much of the riprap to be placed would fill in portions of the bank which at present have become scoured out -- between the existing gabions and on the upper slope near the building supports -- and would tend to restore the pre-scoured slope of the bank. On the north bank slope, the presence of a rock wall which protects an existing vault at the upstream side of the library (see Figure 2), already blocks or obstructs some conveyance of flow along the north bank slope. The addition of revetment on the slope immediately downstream is therefore unlikely to have significant impacts to water levels. As a check, this condition was also approximately modeled using HEC-RAS. The results of the model did not show any increase in water level nor any significant change in velocities due to presence of the revetment. northwest hydraulic consultants inc. Jim Paxton, City of Renton 4 May 25, 1999 It was also determined with the HEC-RAS model that a partial or full removal of the rock wall (protecting the vault) could lower Cedar River water levels between Houser Way and the Renton Library by up to 0.5 ft. This, of course, may not be feasible unless other alternatives to protect the vault are considered. The vault, by itself, would not be an obstruction to flow.
