These plans have been modified in accordance with recent plan review comments compiled from the various City of Renton reviewing departments. More specifically, the revisions that we have made are as follows: The City of Renton Fire Department has indicated that the minimum fire protection requirements for this project shall be 2,000 gallons per minute of fire flow drawn from one fire hydrant located within 150 feet of the proposed building structure. To meet this minimum requirement we have proposed to install a new fire hydrant along the frontage of N.E. Sunset Boulevard adjacent to the subject property. This fire hydrant will be within 150 feet of the mini -market facility and have a fire flow in excess of 2,000 gallons per minute. 2. The Utility Engineering Division requested that a Water Main Extension Plan shall be prepared and approved for installation of the new fire hydrant. The water main extension design and appropriate construction information is provided on the Site and Utility Plan for this project. The Utility Engineering Division has indicated that secondary containment is required for all underground gasoline storage tanks. The construction drawings which illustrate the product dispensing system is in accordance with this requirement. These plans were included in our original sub- mittal to the City of Renton for the purpose of obtaining a Commercial Building Permit. 4. The City of Renton Engineering Division has made several minor review comments on the set of plans that were returned to our office for the purpose of addressing plan review comments. Each and every comment has been addressed accordingly. Upon approval of these revisions we shall submit the original mylars to finalize the approval process of the civil engineering plans.

New channelization on Duvall Avenue is required by the City of Renton Traffic Engineering Division. The proposed channelization is provided within the attached plans for review by the Traffic Engineering Division. 6. With respect to stormwater utilities, it has been requested that we provide a detail of the controlled outlet manhole and a profile of the detention pipe. This information has been incorporated onto the detail sheet for this project, Sheet C-4A of 5. 7. A temporary erosion and sedimentation control pond shall be installed during construction of this project in accordance with current City of Renton standards. A Temporary Erosion and Sedimentation Control Plan is attached for your review. The Drainage/Detention Report has been modified to include a downstream analysis (minimum of one -quarter mile) of the existing storm drainage system to Honey Creek. The downstream analysis is in the form of a narrative of our site investigation, which is located on pages 2 and 3 of the Drainage/Detention Report. Would you please proceed to process the enclosed information at your earliest possible convenience. I would like to express that our client is extremely anxious to begin construction of this project, therefore, your earliest attention with respect to these plan modifications will be greatly appreciated.

AND N.E. SUNSET BOULEVARD RENTON, WASHINGTON MARCH 23, 1988 ARCO FAC NO. 5491/OUR JOB NO, 2281 INTRODUCTION AND GENERAL INFORMATION: The proposed project lies in a portion of the East half of the Southwest quarter of Section 3, Township 23 North, Range 5 East of the Willamette Meridian in Renton, Washington and is approximately 0.8 acres in size. The subject property is presently used as a nursey and florist shop. The nursery occupies 1.213 acres which are to be subdivided into two lots; the subject property will occupy the southern lot. The subject property is approximately rectangular in shape and is bounded on two sides by public roadway. Duvall Avenue N.E. provides approximately 145 feet of frontage along the east property boundary, and N.E. Sunset Boulevard provides approximately 110 feet of frontage along the south property boundary. The existing groundcover is composed ofapproximate- ly 0.2 acres of pavement and buildings and approximately 0.6 acres of gravel with minimal vegetation. The topographic features of the subject property consist of 1 to 4 percent downward slopes from the northeast to the southwest. This topography is consistent with the surrounding area. The proposed project is to construct a 2,500 square foot, single -story, wood frame mini- market facility and a new free-standing canopy with two tandem pump islands for the retail distribution of gasoline, together with the associated underground gasoline storage tanks. The building structure shall be located in the northwest section of the property and the gas pumps shall be located near the mid -section of the east property line, both of these being surrounded by appropriate parking and landscaping. Since the proposed project will increase the impervious area, consequently increasing stormwater runoff, detention will be required. Research of various city records has revealed that the subject property lies within an area requiring detention design for a 25-year storm and a release rate for a 5-year storm. The topographic survey shown on the design plans for this project has been prepared by Barghausen Consulting Engineers, Inc. OFF -SITE DRAINAGE CONSIDERATIONS: From a site investigation and reference to the attached tributary maps, it is realized that the subject property lies within a large drainage basin, which drains in a southerly direction. The lot adjacent to the north property boundary is presently owned by the nursery and slopes toward the subject property. Storm water runoff from its 0.1 acres of pavement and 0.3 acres of gravel flows onto the subject property. Approximately 75 2281.16 -1- feet north of the north property boundary lies a steep slope which rises 10-to-12 feet. The two lots to the north of this rise slope away from the subject property towards S.E. 107th Place. Storm -water runoff from these two lots and from the remainder of the upland basin is intercepted by grass -lined swale in S.E. 107th Place and is conveyed downstream, bypassing the subject property. Similarly, stormwater runoff from Duvall Avenue N.E. is intercepted via curb and gutter. Stormwater runoff from the 14-foot strip adjacent to the eastern property boundary and within the right-of-way of Duvall Avenue N.E. is collected in the catch basin near the southeast corner of the property boundary. Thus stormwater runoff from the east also bypasses the subject property. By noting the topography of the subject property, it is obvious that stormwater runoff shall not drain onto the subject property from either the west or the south. Consequently, the only off -site drainage comes from the 0.4 acre lot immediately to the north of the subject property. This off -site drainage is considered in the following drainage computa- tions. ON -SITE DRAINAGE CONSIDERATIONS: The subject property consists of one drainage basin which currently discharges Storm - water runoff as sheet flow to the south as dictated by topography. The project site will be regraded to minimize pavement slope and to maintain the existing drainage patterns. The storm drainage provided for the project will be in accordance with the City of Renton standards and guidelines. The system, as it is designed, will be relatively maintenance -free and provide the necessary detention for stormwater flows on this project. The tightlined drainage system which will be constructed per the Grading/Storm Drainage Plan will ensure that storm drainage from the developed area will be conveyed through the detention system as required by the City of Renton. The detention facility shall be equipped with an oil/water separator and a multiple -orifice outlet control structure. Stormwater flows shall discharge from the flow-restrictor control structure into the existing conveyance system located in the north margin of N.E. Sunset Boulevard at the 5-year pre -developed release rate. The proposed storm drainage system will be sized to adequately to handle runoff produced by a 25-year storm. Please reference the drainage and pipe sizing calculations provided in this report. DOWNSTREAM DRAINAGE ANALYSIS: As previously mentioned, the proposed drainage system is designed to detain all on -site storm drainage runoff and release this stormwater at no greater than the existing discharge rate for a 5-year storm. Therefore, the downstream drainage system will not be affected by the increase of on -site stormwater runoff produced by this project. 2281.16 -2- DETENTION CALCULATION 3_ Zq -88 Job No .
