This investigation is in conjunction with the redevelopment of the DCT Industries property, which was initially designated as Parcel 1 under the original Technical Information Report (TIR) for the Plumbers and Pipefitters Regional Stormwater Retention Facility, dated June 1994 (see Appendix A.) Under the original design there were six parcels within the drainage basin area, totaling 44 acres and within that there was 25.5 acres of impervious surfaces. Each parcel was allocated a specific area of impervious surface, with the exception of the Metro Parcel. This Parcel was not given an allotment for allowable tributary impervious surface. The tributary area from this Parcel was 1.24 acres of pervious area. The original Parcels were identified as Parcels 1, 2, 3, 4A and 4B and Metro. Using the City of Renton's web -based GIS data, the six parcel areas and impervious surfaces for each were checked to compare between the original allocation and current conditions. Copies of the GIS data used are included in this report. The total original allocation for tributary impervious surfaces was 25.5 acres that was divided amount five of the six parcels. As noted above, the Metro Parcel was not allocated to drain impervious surfaces to the regional stormwater shared facility. Of the five parcels with an allotment for tributary impervious surfaces, three have a smaller area of impervious surface than what was allowed. The overall existing impervious surface area tributary to the facility totals approximately 24.06 acres, leaving a 1.44 acre balance. Exhibit A that follows provides a summary area table. The existing regional stormwater shared facility consists of two ponds. These ponds are located on Parcels 2, 4A and 4B. The existing area of these ponds was checked to compare ponds total volume to the original design. The original topographic survey maps were used along with the topographic contours taken from the City's GIS to develop an "existing" storage volume for these ponds. A summary table of the calculated volumes is provided as Exhibit J, and is entitled "Existing Pond Storage Volumes" and summary table This investigation also included a review of the City of Renton's current 2017 City of Renton Surface Water Design Manual which allows for "Shared Facility Drainage Plans" (SFDP's) which the DCT Industries property and five other properties are part of. This SFDP was originally developed and approved by the City of Renton. Using the information within this report; there is about 1.44 acres of unallocated impervious surface area within the boundary of this shared facility drainage plan. The proposed DCT Industrial redevelopment of their parcel (which was originally noted as Parcel 1) is proposing to increase their impervious surface area by about 63,000 square feet or about 1.44 acres. This increase will fall under the original design parameters of the pond storage and its pumps capacity. Therefore no change to the existing system is warranted for the redevelopment of this parcel. There is one item that does need to be addressed; There is an existing surface area from Monster Road SW which has been diverted to this regional stormwater facility which was not originally allocated to it. This roadway area abuts Parcel 1, 2 and part of 3 and generally flows from east to west around the building on Parcel 2 and on to the north pond area. The surface area from this roadway area is about 54,000 square feet or about 1.24 acres. As noted; this area was not allocated to the "Shared Facility Drainage Plan" nor was it part of the Regional Detention Facility Pump Station Agreement and Reciprocal Easements.

Flow Control Facilities. Under 1.2.3.2 Flow Control Facilities Implementation Requirements; "A. Onsite vs. Offsite Implementation" page 1-45 it notes; All required flow control facilities must be implemented onsite except where the requirements below can be met by direct discharge to a regional or shared facility constructed to provide flow control for the proposed project... Shared facilities may be constructed under a City -developed shared facility drainage plan or under an agreement between two or more private developers. 1. The regional or shared facility must be of adequate size and design to meet the current flow control requirements for the proposed project. Note: the current flow control requirements are those specified by Core Requirement # 3 of this manual unless superseded by other adopted area -specific flow control requirements per Special Requirement #1 (see Section 1.3.1). In some cases where the current flow control requirements differ from those used to originally design the regional or shared facilities, additional analysis and possible retrofitting of the facility may be required to ensure adequate size and design. In other cases where the current flow control requirements are not significantly different or are less stringent, adequate size and design may already be documented by an adopted City basin plan or master drainage plan, and approved shared facility drainage plan, or a detailed drainage analysis approved by the City for a separate permitted developed. 2. The regional or shared facility must be fully operational at the time of construction of the proposed project. In the case of a shared facility, the proposed project must comply with the terms and conditions of all contracts, agreements, and permits associated with the shared facility. If the offsite facility is an existing City - owned facility, the City may charge a special use fee equal to or based on the property value of the detention capacity being used. 3. The conveyance system between the project site and the regional facility must meet the same criteria specified for direct discharge to major receiving water except for Criterion (a) (see "Direct Discharge Exemption" in Section 1.2.3.1). In the case of a shared facility, the criteria are the same, except the conveyance system need only have adequate capacity and erosion protection for buildout of the participating portion 26of the contributing drainage area. (26 = The participating portion includes those properties that have agreements for use of the shared facility) Under 1.3.1 Special Requirement # 1 Other Adopted Area- Specific Requirements (page 1-89 of the 2017 City of Renton Surface Water Design Manual) it notes: • Shared Facility Drainage Plans (SFDP's): SFDP's are approved by the City of Renton to allow two or more projects to share drainage facilities required by this manual. Projects covered by a SFDP must meet any special requirements of that plan. Thresholds — IF a proposed project is in an area included in an adopted master drainage plan, basin plan, salmon conservation plan, stormwater compliance plan, hazard mitigation plan, lake management plan, or shared facility drainage plan.... Requirement — THEN the proposed project shall comply with the drainage requirements of the master drainage plan, basin plan, salmon conservation plan, stormwater compliance plan, hazard mitigation plan, lake management plan, or shared facility drainage plan respectively. Application of this Requirement... The drainage requirements of adopted MDP's, BPs, SCPs Hazard Mitigation Plan, lake management plans, and SFDP's shall be applied in addition to the drainage requirements of this manual unless otherwise specified in the adopted regulation. Where conflicts occur between the two, the drainage requirements of the adopted area -specific regulation shall supersede those in this manual... Projects covered by SFDPs shall demonstrate that the shared facility will be available by the time the project is constructed and that all onsite requirements are met. Project covered by a SFDP are still required to provide any onsite controls necessary to comply with drainage requirements not addressed by the shared facility. The only on-site drainage requirement not covered by this shared facility drainage plan is water quality, which will be addressed with the redevelopment of this project. The DCT Industrial parcel was a partner in the development of this "Regional Detention Facility Pump Station Agreement and Reciprocal Agreement and was designated as Parcel 1 under the original Technical Information Report (TI R) for the Plumbers and Pipefitters Regional Stormwater Retention Facility dated June 1994 (see Appendix C). Areas to the Existinq Shared Facility This investigation reviewed the original TIR's surface areas which were used to design the pumps which control the elevation of the drainage facility. The Key Map within this TIR shows the following parcels: Parcel 1 (which is the DCT Industrial property) Parcel 2 (building constructed in 1999) Parcel 3 (shows as lot 1 and 2 but the current conditions show it as 1 lot) Parcel 4-A (current Plumbers and Pipefitters facility) Parcel 4-B (building constructed in 2000) Metro's parcel The report notes: The developed site will consist of 44 acres of commercial development with approximately 25.5 acres of impervious surface area (See Developed Drainage Basin Map). Below are the current King County's Assessor's parcel areas: Parcel Number Square Foot Area Acres Parcel 1 418,876 s.f. 9.62 acres Parcel 2 467,264 s.f. 10.73 acres Parcel 3 309,997 s.f. 7.12 acres Parcel 4-A 262,487 s.f. 6.03 acres Parcel 4-13 325,302 s.f. 7.47 acres Metro 160,301 s.f. 3.68 acres Total 1,944,227 sf 44.63 acres Within the noted original TIR's Developed Drainage Basin Map it shows the expected impervious surfaces for each parcel. Using the City of Renton's GIS web based application to determine the existing specific parcel impervious surface areas, the following was developed. (Also see a spreadsheet titled "Impervious Surface Areas for Parcels under Original & Current (GIS) Conditions") Parcel Number Original Impervious Surface Parcel 1 6.5 acres Parcel 2 8.5 acres Parcel 3 Parcel 4-A Parcel 4-B Metro Total 5.7 acres 2.4 acres 2.4 acres 0 acres 25.5 Current Impervious Surface 6.1 acres 8.8 acres 5.2 acres 2.5 acres 1.4 acres 0 acres 24.06 The overall difference between the originally proposed 25.5 acres of impervious surfaces and the existing 24.1 acres of impervious surfaces is about 1.44 acres of non allocated impervious surfaces based on parcel areas only. The proposed DCT Industrial project improvements will increase the impervious surface area on this parcel. The proposal will add 15,000 square feet of roof area and 48,000 of pollution generating surface area, or about 63,000 s.f. or 1.44 acres. Using the existing "Shared Facility Drainage Facility' and the proposed increase in impervious surface for the Parcel 1 property (DCT Industrial property); there will be no increase in impervious surface areas going to this facility. There is one area going to this shared drainage facility that was not included in the original design. There is about 54,048 square feet or 1.24 acres of roadway surfaces from Monster Road SW going to this facility.

There were two storage ponds defined; the north and south ponds which are divided by an existing railroad spur which splits them. There is a 15" equalizing pipe shown on both the existing and developed basin maps between the two storage areas which creates one large storage facility. Under the original TIR, the storage volumes started at elevation 9 for both areas and continue to elevation 19. The total accumulated volume of both areas was determined to be 2,330,453 cubic feet. The current GIS contour surface areas that can be developed were for elevations 16 up to 19 since there are no other contours below this shown. To determine the surface contour areas for elevations below 16, the original surveyed topographic mapping in the original TIR were used (See Appendix A). A spreadsheet was developed to show the existing volume information along with the new updated information. It notes the topographic surfaces used for each elevation, either the original topographic maps or the City's GIS information. Elevations 17 and 19 were assumed but were based on existing GIS contours 16 and 18, since the City's GIS does not include the 1 -foot contours. Using the above contour elevation surface area information, the total estimated accumulated volume of both ponds is around 2,319,140 cubic feet. That amount is around 99.5% of the original calculated volume and that minor difference can be attributed to a rounding error based on the data we have available to calculate this. Therefore our conclusion is that the current volume is essentially the same as the original design volume.

AND MONSTER ROAD THAT DRAINS TO AN EXISTING POND BEHIND THE ELAND DISTRIBUTION FACILITY. THIS POND SERVES AS A REGIONAL DETENTION FACILITY FOR THE BLUME PARCEL SEGRETATION. CURRENTLY, PARCELS 1 AND 2 ARE DEVELOPED WITH LARGE DISTRIBUTION AND MANUFACTURING BUILDINGS AND PARCELS 3, 4A AND 4B ARE UNDEVELOPED WITH TREES, BRUSH AND WETLAND AREAS. THE EXISTING IMPERVIOUS AREA IS 15.9 ACRES. SOILS ON THE SITE ARE A MIXTURE OF WOODINVILLE, PUGET, PUYALLUP AND BEAUSITE. SINCE THE MAJORITY OF THE SOIL IS WOODINVILLE OF THE HYDROLOGIC GROUP "D" AND HAS A MIXED USE OF MEADOW AND FOREST, A COMPOSITE CURVE NUMBER OF 85 IS USED IN THE DRAINAGE ANALYSIS CALCULATIONS. THE TIME OF CONCENTRATION THROUGH THE SITE FROM THE HILL SOUTH OF PARCEL 3 THROUGH THE CONTAINER CORPORATION DRAINAGE SYSTEM AND TO THE POND IS 33.66 MINUTES (SEE EXISTING DRAINAGE BASIN MAP).
