The site is located southwest of the intersection of South 7th Street and Cedar Avenue South in Renton, Washington. The proposed lots would range in size from 6,595 square feet to 7,989 square feet. The proposed lots would be accessed via private driveways from Cedar Ave S. The project site is roughly 1.5 acres in size and is currently covered in grass. The site was mass graded as part of the 1-405 project, so there will be no clearing and minimal grading to construct seven single family lots, stormwater vault and associated utilities. One combined detention and water quality treatment vault will be located at the south end of Cedar Ave S in the cul-de-sac. Half street frontage improvements will be constructed on the west side of Cedar Ave S. The site contains sensitive areas, such as coal mine hazards, erosion hazards, steep slopes, and landslide hazards. The applicant submitted a Technical Information Report, Geotechnical Engineering Services Critical Areas Report, Coal Mine Hazard Assessment, and an exception through a waiver under RMC 4-3-050J.5.d for the placement of a wedge-shaped sliver fill and part of a retaining wall within the protected slope area on proposed Tract A. PROJECT LOCATION: 700-800 Block of Cedar Ave S LEAD AGENCY: City of Renton Environmental Review Committee Department of Community & Economic Development The City of Renton Environmental Review Committee has determined that it does not have a probable significant adverse impact on the environment.

Technical Services Bob MacOnie Ph: 425-430-7369 email: bmaconie@rentonwa.gov Recommendations: The property at issue needs to be properly subdivided via a Lot Line Adjustment from that portion of the underlying two parcels reserved by WSDOT in their conveyance to the applicant. This will change the legal description of the property at issue. Note the City of Renton land use action number and land record number, LUA14-000568 and LND-20-0602, respectively, on the final ERC Mitigation Measures and Advisory Notes Page 2 of 5 short plat submittal. The type size used for the land record number should be smaller than that used for the land use action number. The legal description on the final short plat will need to be revised to reflect the lot line adjustment required to properly segregate the property at issue from the property reserved by WSDOT by conveyance to the applicant. The dedication of right of way for short subdivisions requires a separate Deed of Dedication; provide a space to the recording number of same on the short plat. The Deed of Dedication document includes both a legal description exhibit and a map exhibit of the dedicated parcel. The legal description exhibit should be prepared, stamped, dated and signed by the applicant's surveyor. The surveyor should also prepare the map exhibit. The dedication process requires an updated Plat Certificate dated within 45 days of approval of said dedication. Talk to the Project Manager if there are questions or further information is needed. Show two ties to the City of Renton Survey Control Network. The geometry will be checked by the city when the ties have been provided. Provide sufficient information to determine how the plat boundary was established. Include a statement of equipment and procedures used, per WAC32-130-100. Provide short plat and lot closure calculations. Indicate what has been, or is to be, set at the corners of the proposed lots. Note discrepancies between bearings and distances of record and those measured or calculated, if any. The city will provide addresses for the proposed lots as soon as possible. Note said addresses on the final short plat drawing. Do nate encroachments, if any. Do include a "LEGEND" block for the short plat drawing, detailing any symbols used thereon. Do not include topography and utility infrastructure as they are only part of the initial submittal requirements unless they have a direct influence on the subdivision. Note all easements, covenants and agreements of record on the drawing. Note any relevant researched resources on the short plat submittal. Note the plat name and lot and tract numbers of the adjoining properties or note as "Unplatted." Remove the building setback lines noted on the final short plat lots. Setbacks will be determined at the time that building permits are issued. ERC Mitigation Measures and Advisory Notes Page 3 of 5 The City of Renton Administrator, Public Works Department, is the only city official who signs the final short plat. Provide an appropriate approval block and signature line. Pertinent King County approval blocks also need to be noted on the drawing. All vested owners) of the subject final short plat need to sign the final short plat drawing. Include notary blocks as needed. Include a declaration block on the drawing, titled "OWNERS' DECLARATION" riot "CERTIFICATION" or other.

The final short plat drawing and the associated document(s) are to be given to the Project Manager as a package. The recording number(s) for the associated document(s) are to be referenced on the final short plat drawing. Provide spaces for the recording numbers thereof. The new easements for the benefit of future owners of the proposed lots each need a note defining the rights associated with the easement at issue. Since these new "proposed" easements shown aren't "granted and conveyed" until the benefited and/or burdened lots are conveyed to others add the following language on the face of the short plat drawing: DECLARATION OF COVENANT: The owners of the land embraced within this short plat, in return for the benefit to accrue from this subdivision, by signing hereon covenant and agree to convey the beneficial interest in the new private easements shown on this short plat to any and all future purchasers of the lots, or of any subdivisions thereof. This covenant shall run with the land as shown on this short plat. The preceding statement obligates the seller of the lots created to "expressly grant and convey" the lots "together with and/or subject to any new private easements delineated on the short plat in the conveying document.
