Fesser J:>1 Dalpay Plat Phase III, LUA-07-119, PP Format and Legal Description Review Bob Mac Onie and I have reviewed the above referenced preliminary plat submittal and have the following comments: Comments for the Applicant: The current submittal language/format shown is applicable for a short plat, not a long plat, which is what this subdivision is. The "CERTIFICATION" block that is shown should be replaced with one that is appropriate for a long plat. Make other changes as needed, such as removing all references to "SHORT" from the title block, "Aquifer Protection Notice" block, and other places. Information needed for final plat approval includes the following: Note the City of Renton land use action number and land record number, LUA-08-XXX-FP and LND-10-0464, respectively, on the drawing. The type size used for the land record number should be smaller than that used for the land use action number. Please note that the land use action number for the final plat will be different from the preliminary plat and is unknown as of this date. Provide final 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. Note all easements, covenants and agreements of record on the drawing. \H:\File Sys\LND -Land Subdivision & Surveying Records\LND-10-Plnts\0464\RV0712I4.doc January 7, 2008 Page 2 Note the plat names and lot numbers of the properties adjoining on all sides of the subject parcel, or if not platted, use "UNPLATTED". The city will provide addresses for the proposed lots after the preliminary plat is approved. Note said addresses on the final plat drawing. On the final plat submittal, remove all references to trees (including the "TREE LEGEND"), topog lines and other items not directly impacting the subdivision. These items are provided only for preliminary plat approval. Remove the "CONTOUR INTERVAL" block (Sheet 2 of 2). The City of Renton Administrator of Planning/Building/Public Works, the Mayor and the City Clerk sign the final plat submittal. Also needed is an approval block for the City of Renton Finance Director. Provide appropriate approval blocks and signature lines. Pertinent King County approval blocks (for a long plat) are also needed on the drawing submittal. Note the dimension for the west line of proposed Lot 3 on the drawing sheet (Sheet 2 of 2). All vested owner(s) of the subject final plat need to sign the final plat drawing. Include notary blocks as needed. Note that if there are easements, agreements or restrictive covenants to, and/or by others (neighboring property owners, etc.) as part of this subdivision, they can be recorded concurrently with the plat. The 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) (said documents recorded concurrently with, but following the plat) need to be referenced on the plat drawings. The following language concerning ownership of "Tract A" (sensitive area) applies to this plat and should be noted on the final plat drawing as shown, ![there is to be a Homeowners' Association (HOA): Upon the recording of this plat, Tract A is hereby granted and conveyed to the Dalpay Phase fl! Plat Homeowners' Association (HOA) for a sensitive area. All necessary maintenance activities for said Tract will be the responsibility of the HOA. In the event that the HOA is dissolved or otherwise fails to meet its property tax obligations, as evidenced by non-payment of property taxes for a period of eighteen ( 18) months, then each lot in this plat shall assume and have an equal and undivided ownership interest in the tract previously owned by the HOA and have the attendant financial and maintenance responsibilities. If no HOA is established, then use the following language on the final plat drawing: Lots 1 through 4, inclusive, shall have an equal and undivided ownership interest in "Tract A". H:\File Sys\LND -Land Sub<livision & Surveying Records\LND-10 -Plats\0464\RV0712 l4.doc\cor January 7, 2008 Page 3 The foregoing statement is to be accompanied by language defining the maintenance responsibilities for any infrastructure located on the Tract serving the plat, or reference a separate recording instrument detailing the same. The new 26'X20' wide casement, for ingress, egress and utilities, is shown for the benefit of future owners of proposed Lots 2, 3 ('') and 4. Note on the drawing the following statement: "Area for private 26'X20' ingress, egress and utility easement". Since the new lots created via this plat are under common ownership at the time of recording, there can be no new easement established until such time as ownership of the lots is conveyed to others, together with and/or subject to specific easement rights. Add the following Declaration of Covenant language on the face of the subject drawing, if the previous paragraph applies: DECLARATION OF COVENANT: The owners of the land embraced within this 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 easement( s) shown on this plat to any and all future purchasers of the lots, or of any subdivisions thereof: This covenant shall run with rhe land as shown on this plat. The private ingress, egress and utility easement requires a "New Private Easement for Ingress, Egress and Utilities Maintenance Agreement" statement. Note the attachment on the drawing. Is the 20' wide easement shown over property to the east of proposed Lot 3 recorded? If so, add the recording number to the plat drawing. Need an additional specific easement document (on a city form) be recorded over said easement strip for Lots 2, 3 and 4? Sheet I of 2 references a Declaration of Covenants and Restrictions document. Said document was not included in the plat package we received for review.

Ding, Senior Planner The applicant is requesting Preliminary Plat approval and Environmental (SEPA) Review for the subdivision of an existing 72,332 square foot lot zoned Residential -8 dwelling units per acre (R-8) into 4 lots. The project site was previously part of the Dalpay Estates Div II short plat (LUA03-125), which was recorded in September of 2005 (recording# 20050927900007). As the site was previously part of a subdivision that was recorded less than 5 years ago, the current subdivision is required to be reviewed as a preliminary plat. The proposed lot sizes are as follows: Lot 1 is 8,140 square feet, Lot 2 is 12,985 square feet, Lot 3 is 12,879 square feet, and Lot 4 is 7,462 square feet. Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 would be provided via a private street off of Redmond Court NE. Steep slopes and an unnamed stream are located on the project site and would be protected in a sensitive area tract. 1801 Redmond Place NE City of Renton P!B!PW Department DALPAY PRELIMINARY PLAT PHASE Ill Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page 2of9 B.

The project site is located south of NE 19th Street and west of Redmond Court NE and is zoned Residential -8 (R-8) dwelling units per acre. The proposed lot sizes are as follows: Lot 1 is 8,140 square feet, Lot 2 is 12,985 square feet, Lot 3 is 12,879 square feet, and Lot 4 is 7,462 square feet. Protected slopes and an unnamed stream are located on the central portion of the project Ji\!' and would be protected within an NGPE. No development is proposed on the protected slopes or within .wfeet of the stream. The grading would be limited to the construction of the proposed private street and utilities. Approximately 200- 300 cubic yards of grading is proposed. Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 would be provided via a private street off of Redmond Court NE. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21 C, 1971 as amended), on November 5, 2007, the Environmental Review Committee issued a Determination of Non-Significance -Mitigated Hexrpt 07-119.doc City of Renton P!B!PW Department DALPA Y PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 4 of9 (DNS-M) for the Dalpay Preliminary Plat Phase Ill. The DNS-M included 6 mitigation measures. A 14-day appeal period commenced on November 13, 2007 and ends on November 27, 2007. As of the composition of this report no appeals of the threshold determination have been filed. 3. COMPLIANCE WITH ERC MITIGATION MEASURES 1. The construction of new single family residences shall maintain a 25-foot buffer from the edge of the protected slope, unless based on appropriate subsurface exploration and slope stability analysis a geotechnical engineer concludes that the 25-foot buffer may be reduced. 2. The applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed pursuant to the Department of Ecology's Erosion and Sediment Control Requirements outlined in Volume II of the 2005 Stormwater Management Manual and provide staff with a Construction Mitigation Plan prior to issuance of Construction Permits. This condition shall be subject to the review and approval of the Development Services Division. 3. The storm drainage system for this project shall be required to comply with the requirements found in the 2005 King County Surface Water Design Manual. 4. The applicant shall pay a Parks Mitigation Fee based on $530. 76 per each new single family lot. The fee is estimated at $2,123.04. 5. The applicant shall pay a Traffic Mitigation Fee in the amount of $75 for each new net daily trip prior to the recording of the final plat. It is anticipated that the proposed project would result in the payment of $2,871.00. 6. The applicant shall pay a Fire Mitigation Fee based on $488.00 per new single family lot prior to the recording of the final plat. The fee is estimated at $1,952. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. Lands in the RSF designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies: Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. The proposal project for four lots would arrive at a net density of 4.25 dwelling units per net acre on the project site, which is within the density range required. The proposal to re-subdivide the Dalpay Estates Division 2 parent parcel into a total of 8 lots would arrive at a net density of 4.5 dwelling units per net acre, which is within the density range required. ' ' "). , : ,:,. // i-) \._ /~-·"'·- Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of fess than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on lot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation, but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page 5of9 All of the proposed lots equal or exceed the minimum lot size of 5,000 square feet. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. The proposed new lots would meet the required lot size, width, and setbacks area. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of life for existing residents. The proposed lots are oriented such that all of the lots would have access to a public right-of-way. Approval of this application would not decrease the quality of life for residents in the immediate vicinity. Policy CD-12. Infill development, defined as new short plats of nine or fewer lots, should be encouraged in order to add variety, updated housing stock, and new vitality to neighborhoods. The proposed short plat would subdivide one existing parcel into four lots. Four new residences would be constructed on the new lots, updating the housing stock in the existing neighborhood. B. Compliance with the Underlying Zoning Designation. The 1.66-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of 4 new single-family residential units. Density-The R-8 zone requires a minimum density of 4.0 dwelling units per net acre (du/ac) and permits a maximum density of 8.0 dwelling units per net acre. Net density is calculated after public rights-of-way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 520 square feet of private streets, and 30,866 square feet of critical areas, the proposal for 4 lots would result in a net density of 4.25 dwelling units per acre (4 lots / 0.94 acres = 4.25 dulac). In addition, staff reviewed the proposed subdivision in the context of the previously approved Dalpay Estates Division 2 Short Plat. The proposal to subdivide the parent Dalpay Estates Division 2 parcel into 8 lots would result in a density of 4.5 dwelling units per acre. The proposed subdivision would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone is 5,000 sq ft for parcels that total less than 1 acre in net area. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. The proposed plat would create four lots, Lot 1 would have a lot area of 8,140 square feet, Lot 2 would have a lot area of 12,985 square feet, Lot 3 would have a lot area of 10,929 square feet, and Lot 4 would have a lot area of 7,462 square feet. All of the lots would be interior lots as none of the lots abut a public street. The proposed lots would have lot widths ranging from 67 feet to 90 feet. The proposed lots would have lot depths ranging from 84 feet to 223 feet. As proposed the new lots would comply with the City's minimum lot size, width and depth requirements. Setbacks -In the R-8 zone, the minimum front and side yard along street setbacks are 15 feet for the primary residence and 20 feet for an attached garage, the minimum interior side yard setback is 5 feet and the minimum rear yard setback is 20 feet. The proposed lots appear to contain adequate area to provide for the construction of single family residences after the consideration of the setback requirements. Compliance with these setback standards will be verified prior to the issuance of individual building permits. Building Standards -The R-8 zone permits one single family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 sq ft each, or one per lot at 1,000 sq ft in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is 35% or 2,500 square feet, whichever is greater. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPA Y PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DATE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 6 of 9 The proposal's compliance with these building standards would be verified prior to the issuance of individual building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping -The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum amount of landscaping required for sites abutting a non-arterial public street is 5 feet provided that if there is additional undeveloped right-of-way in excess of 5 feet, this shall also be landscaped. A determination has been made that if no additional area is available within the public right- of-way due to required improvements, the 5-foot landscaped strip may be located within private property abutting the public right-of-way. The project site does not abut any public street frontages; therefore the 5- foot landscape strip is not required. Two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer) are required to be planted within the 15-foot front yard setback area for the proposed lots. A conceptual landscape plan was submitted with the project application. The landscape plan proposes to plant two Autumn Brilliance Serviceberry trees within the front yard areas of Lot 3 and 4. A total of 4 evergreen trees are proposed to be retained and one 6-7-foot tall Shore Pine is proposed to be planted within the 15-foot front yard area of proposed Lot 2. The submitted plan did not include any trees within the front yard area of proposed Lot 1. The landscape plan shall be revised to include two trees within the front yard area of proposed Lot 1. Staff recommends as a condition of approval that a revised landscape plan be submitted prior to the approval of the final plat showing two trees within the 15-foot front yard area of proposed Lot 1. The revised landscape plan shall be submitted to the Development Services Division project manager for review and approval. The applicant will be required to submit a detailed landscaping plan to the Development Services Division for review and approval prior to the issuance of a building permit. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. As proposed, the lots appear to comply with arrangement and access requirements of the Subdivision Regulations. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. Proposed Lot 1 would be oriented to provide its front yard facing to the north, Lot 2 would be oriented to provide its front yard facing to the south, and Lots 3 and 4 would be oriented to provide their front yards facing to the north. Staff recommends as a condition of approval that a note be placed on the face of the final plat map identifying the orientation of the front yards of each of the new lots. Each of the lots would satisfy the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: There are no property corners at intersections. Access and Street Improvements: Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 is proposed via a 20-foot wide private access street off of Redmond Court NE. Private streets are permitted to serve a maximum of 6 lots provided a minimum of two lots abut a public right-of-way. A joint use driveway is permitted to provide access to a maximum of two lots and is required to have a minimum easement width of 20 feet. The existing 20-foot wide access easement off of NE 1 g'h Street currently is approved to provide access to Lots 1-5 of the Dal pay Estates Division 2 Short Plat that was previously approved. The current project is a re-subdivision of Lot 5 of the Dalpay Estates Division 2 Short Plat. The proposal to provide access to Lot 1 of the proposed subdivision would result in a total of 5 lots accessing off of the easement, which would not exceed the maximum number of 5 lots that were permitted to access off the easement permitted under the Dal pay Estates Division 2 Short Plat. Hexrpl 07-119.doc , City of Renton P/8/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 7 of 9 The existing 20-foot wide access easement off of Redmond Court NE was approved as a part of the Veldyke/Webber Short Plat (LUA05-065) to provide access to a maximum of two lots (one of which being Lot 5 of the Veldyke/Webber Short Plat). Therefore, the proposal to provide access to three additional lots (Lots 2-4) proposed to be created under the current subdivision would exceed the maximum number of lots approved to take access off of the existing 20-foot wide easement. In order to provide access to three additional lots, the easement would need to be widened to 26 feet with 20 feet of paving or a Modification to the City's Street Standards would need to be granted. Staff recommends as a condition of approval that a revised plat map be submitted prior to final plat approval widening the existing access easement proposed to provide access to Lots 2-4 to 26 feet with 20 feet of paving or that a Modification to the City's Street Standards be requested and granted by the Development Engineering Supervisor. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Traffic Mitigation Fee. The Traffic Mitigation Fee is based on $75 per net new average daily trip attributed to the proposed subdivision. The proposed 4 new residential lots would be expected to generate approximately 38.28 new average weekday trips ( 4 new homes x 9.57 trips per home = 38.28). The fee for the proposed plat is estimated to be $2,871 (38.28 total trips x $75.00 = $2,871) and is payable prior to the recording of the plat. Topography and Vegetation: The topography across proposed Lot 1 is relatively flat with a gradual slope towards the protected slope areas located within the proposed NGPE. The topography across Lots 2-4 slopes to the southwest at an average grade of 11 percent. In addition, the topography across the central portion of the site slopes down to a ravine with grades in excess of 40 percent. With the project application, the applicant submitted a Geotechnical Report prepared by Dennis Joule, dated January 16, 2004. The Environmental Review Committee adopted the recommendations found in the submitted geotechnical report as mitigation. A Stream Study prepared by Alder NW, dated November 19, 2007 was submitted for the proposed project. A stream was identified within the ravine located on the central portion of the project site. The stream was classified as an intermittent Class 4 stream. A Class 4 stream requires a 35-foot stream buffer; however the City's Critical Areas Regulations require that when a stream buffer falls within a protected slope, the buffer shall extend to the top of the slope. According to the submitted stream study, portions of the 35-foot required stream buffer falls within the protected slope; therefore where the stream buffer falls within the protected slope area, the buffer extends to the top of the protected slope. No development is proposed within the protected slope or the stream buffer area. To protect the critical areas located on the project site, staff recommends as a condition of approval that a Native Growth Protection Easement shall be recorded over the protected slopes, Class 4 stream, and associated buffer area (Tract A) prior to or concurrent with the recording of the final plat map. To notify future residents of the Dalpay Preliminary Plat Phase Ill of the presence of the critical areas, staff recommends as a condition of approval that the edge of the protected slopes, Class 4 stream, and associated buffer be delineated with a split rail fence and identified with signage as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of Utility Construction Permit Application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The project site is currently forested with a variety of trees, shrubs, and ground cover. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made to preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. A significant tree retention plan was submitted with the project application. According to a tree retention plan that was submitted by the applicant, a total of 96 significant trees are located on-site outside of the NGPE, of those 24 would be required to be retained or replaced. The tree retention plan identifies 44 significant trees that are proposed to be retained, which would comply with the retention requirements. To ensure that none of the trees proposed to be retained are damaged during construction, staff recommends as a condition of approval that the trees proposed to be retained are shown on each of the plans submitted as a part of the Utility Construction Permit Application and that protection measures for the trees to ensure survival during construction of the project be submitted for review and approval by the Development Services Division project manager.

The project application includes a Construction Mitigation Plan, which is subject to final approval prior to the issuance of construction permits for the project. Due to the potential for erosion to occur from the project site during construction, the Environmental Review Committee adopted a mitigation measure requiring that erosion control be installed in accordance with the 2005 Department of Ecology Stormwater Management Manual. Relationship to Existing Uses: Single family residential homes surround the subject site. The proposed detached single family residences would be compatible with the surrounding development. D. Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. These fees paid would help offset any additional impacts to emergency services generated from this development. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Fire Mitigation Fee. The Fire Mitigation Fee is based on a rate of $488.00 per new single family lot. The fee is estimated at $1,952.00 ($488 x 4 = $1,952.00) and is payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling. Based on the student generation factor, the proposed plat would potentially result in 2 additional students (0.44 X 4 = 1.76). Storm Drainage/Surface Water: A Technical Information Report prepared by Cramer Northwest, Inc., dated August 13 2007 was submitted with the application materials. According to the report the existing drainage currently sheet flows to the ravine located on the central portion of the project site, where it becomes a small stream, which flows towards NE Sunset Blvd. The submitted report concludes that the proposed project is exempt from detention and water quality improvements per the 1990 King County Surface Water Design Manual. Due to potential downstream drainage problems, the City's Environmental Review Committee imposed a SEPA mitigation measure that requires the project to comply with the 2005 King County Surface Water Design Manual. Applicant will be required to tightline all roof downspout systems and footing drains to a storm system. A geotechnical report dated January 16, 2004 was submitted. A revised report shall be required with the Utility Construction Permit submitted as the report recommends that the roof and footing drains be tied into the neighboring storm vault being built by the Veldyke/Webber Short Plat. It is not clear if this in option or if both parties have agreed to this. The Surface Water System Development Charges are based on a rate of $759.00 x 4 single-family homes. The estimated fees based on the proposed plat are $3,036.00. Payment of these fees will be required prior to issuance of utility construction permit. Water and Sanitary Sewer Utilities: The subject site is located within the City of Renton water service area. An 8-inch water main will be extended to the east property line within a 26-foot utility and access easement provided by the Veldyke/Webber Short Plat. An 8-inch sewer main is being extended from NE 19th internally into the short plat. Available fire flow from the dead end main will be 1,250 gpm. The proposed project is located in the 300 Water Pressure Zone and is outside an Aquifer Protection Zone. Static pressure in the area is approximately 80 psi. Fire flow requirement for single-family residences under 3,600 square feet, including garage is 1,000 gpm. Hydrants are required within 300 feet of all structures. Existing hydrants to be counted as fire protection will be required to be retrofitted with a 5-inch storz quick disconnect fitting. Additional fire flow and hydrants are required if the total square footage of the new single-family structures are greater than 3600 square feet. Lots 2, 3, and 4 will require residential fire sprinkler systems. A minimum of a one inch domestic water meter will be required.

ERC Mitigation Measures Page 1 of 1 December 10, 2007 VelDyke Realty, lnc. 5500 Rainier Avenue South Seattle, WA 98118 Re; Dalpay Preliminary Plat Phase 111 LUA07-119,PP,ECF Dear Chief Daniels, I am writing with regards to the pending short plat and December 4, 2007 Hearing Examiner's meeting. My name is Cheryl Webber-Veldwyk (Webber-VelDyke Plat) and I am currently developing the plat adjacent (to the west of) the Dalpay Plat. I testified to the Hearing Examiner on December 4, 2007 and the pending Dalpay short plat has been put on hold. Dalpay has been requested to negotiate with Webber- Ve!Dyke in acquiring an additional 6' to the 20' easement road for the access to the Dalpay plat. This would now serve 5 homes. (1 serving Webber-Ve!Dyke, 4 serving Dalpay) When the City of Renton approved the Webber-Ve!Dyke plat on August 17, 2005 its conditions were to provide 20' easement road for the future developing of the Dalpay Plat this was written to serve TWO LOTS ( I Dalpay and I Webber-Ve!Dyke) and the stubbing out for water and sewer to serve the Dalpay's lot. I have been developing this since August 17, 2005 at my expense, as written and with no communications from Dalpay of their changing intentions. The overall project is now 70% from completion and approximately $500,000.00 for its improvement. I have recently been notified of Dalpay's intention to increase his plat to 4 lots. The result ofDalpay's increase in building lots will compromise safety and could be a liability to the City of Renton, because emergency vehicle access will be limited if a modification be granted by Public Works and the Fire Department in lieu of taking the recommendations of the City ofRenton's to negotiate a 6' easement from Webber- Ve!Dyke. This would then comply with City Street Standards for emergency vehicles access. The primary reason for writing this email is that I respectfully ask that the City of Renton Fire Department make a recommendation to the Public Works not to grant this modification due to compromising the safety of his future homeowners. j 1 have no problem granting a 6' easement to the Da!Pay's through negotiations. But in the event a modification is granted the safety would be compromised for emergency vehicles access to future home owner's and potentially could become a liability to the City of Renton. Ms. Kayren Kittrich from the Public Works Department agreed I was l 00% correct in my testimony with safety. Ms. Kittrich was generally surprised no conditions and comments were made by the Fire Department. I respectfully ask you, should this modification be presented to the City of Renton Fire Department or The Public Work Department to deny it as The Dalpay's and Webber- VelDyke can make all these reasonable conditions happen with out compromising the safety of the future home owners.

It is anticipated that the proposed project would result in the payment of $2,871.00. 6. The applicant shall pay a Fire Mitigation Fee based on $488.00 per new single family lot prior to the recording of the final plat. The fee is estimated at $1,952. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. Lands in the RSF designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies: Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. The proposal project for four lots would arrive at a net density of 4.25 dwelling units per net acre on the project site, which is within the density range required. The proposal to re-subdivide the Dalpay Estates Division 2 parent parcel into a total of 8 lots would arrive at a net density of 4.5 dwelling units per net acre, which is within the density range required. Policy LU-148. A minimum Jot size of 5,000 square feet should be allowed on in-fill parcels of Jess than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on Jot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation. but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page 5 of 9 All of the proposed lots equal or exceed the minimum lot size of 5,000 square feet. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. The proposed new lots would meet the required lot size, width, and setbacks area. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of life for existing residents. The proposed lots are oriented such that all of the lots would have access to a public right-of-way. Approval of this application would not decrease the quality of life for residents in the immediate vicinity. Policy CD-12. Infill development, defined as new short plats of nine or fewer lots, should be encouraged in order to add variety, updated housing stock, and new vitality to neighborhoods. The proposed short plat would subdivide one existing parcel into four lots. Four new residences would be constructed on the new lots, updating the housing stock in the existing neighborhood. B. Compliance with the Underlying Zoning Designation. The 1.66-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of 4 new single-family residential units. Density-The R-8 zone requires a minimum density of 4.0 dwelling units per net acre (du/ac) and permits a maximum density of 8.0 dwelling units per net acre. Net density is calculated after public rights-of-way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 520 square feet of private streets, and 30,866 square feet of critical areas, the proposal for 4 lots would result in a net density of 4.25 dwelling units per acre (4 lots / 0.94 acres = 4.25 du/ac). In addition, staff reviewed the proposed subdivision in the context of the previously approved Dalpay Estates Division 2 Short Plat. The proposal to subdivide the parent Dalpay Estates Division 2 parcel into 8 lots would result in a density of 4.5 dwelling units per acre. The proposed subdivision would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone is 5,000 sq ft for parcels that total less than 1 acre in net area. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. The proposed plat would create four lots, Lot 1 would have a lot area of 8,140 square feet, Lot 2 would have a lot area of 12,985 square feet, Lot 3 would have a lot area of 10,929 square feet, and Lot 4 would have a lot area of 7,462 square feet. All of the lots would be interior lots as none of the lots abut a public street. The proposed lots would have lot widths ranging from 67 feet to 90 feet. The proposed lots would have lot depths ranging from 84 feet to 223 feet. As proposed the new lots would comply with the City's minimum lot size, width and depth requirements. Setbacks -In the R-8 zone, the minimum front and side yard along street setbacks are 15 feet for the primary residence and 20 feet for an attached garage, the minimum interior side yard setback is 5 feet and the minimum rear yard setback is 20 feet. The proposed lots appear to contain adequate area to provide for the construction of single family residences after the consideration of the setback requirements. Compliance with these setback standards will be verified prior to the issuance of individual building permits. Building Standards -The R-8 zone permits one single family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 sq ft each, or one per lot at 1,000 sq ft in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is 35% or 2,500 square feet, whichever is greater. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 6019 The proposal's compliance with these building standards would be verified prior to the issuance of individual building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum amount of landscaping required for sites abutting a non-arterial public street is 5 feet provided that if there is additional undeveloped right-of-way in excess of 5 feet, this shall also be landscaped. A determination has been made that if no additional area is available within the public right- of-way due to required improvements, the 5-foot landscaped strip may be located within private property abutting the public right-of-way. The project site does not abut any public street frontages; therefore the 5- foot landscape strip is not required. Two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer) are required to be planted within the 15-foot front yard setback area for the proposed lots. A conceptual landscape plan was submitted with the project application. The landscape plan proposes to plant two Autumn Brilliance Serviceberry trees within the front yard areas of Lot 3 and 4. A total of 4 evergreen trees are proposed to be retained and one 6-7-foot tall Shore Pine is proposed to be planted within the 15-foot front yard area of proposed Lot 2. The submitted plan did not include any trees within the front yard area of proposed Lot 1. The landscape plan shall be revised to include two trees within the front yard area of proposed Lot 1. Staff recommends as a condition of approval that a revised landscape plan be submitted prior to the approval of the final plat showing two trees within the 15-foot front yard area of proposed Lot 1. The revised landscape plan shall be submitted to the Development Services Division project manager for review and approval. The applicant will be required to submit a detailed landscaping plan to the Development Services Division for review and approval prior to the issuance of a building permit. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. As proposed, the lots appear to comply with arrangement and access requirements of the Subdivision Regulations. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. Proposed Lot 1 would be oriented to provide its front yard facing to the north, Lot 2 would be oriented to provide its front yard facing to the south, and Lots 3 and 4 would be oriented to provide their front yards facing to the north. Staff recommends as a condition of approval that a note be placed on the face of the final plat map identifying the orientation of the front yards of each of the new lots. Each of the lots would satisfy the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: There are no property corners at intersections. Access and Street Improvements: Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 is proposed via a 20-foot wide private access street off of Redmond Court NE. Private streets are permitted to serve a maximum of 6 lots provided a minimum of two lots abut a public right-of-way. A joint use driveway is permitted to provide access to a maximum of two lots and is required to have a minimum easement width of 20 feet. The existing 20-foot wide access easement off of NE 191" Street currently is approved to provide access to Lots 1-5 of the Dal pay Estates Division 2 Short Plat that was previously approved. The current project is a re-subdivision of Lot 5 of the Dalpay Estates Division 2 Short Plat. The proposal to provide access to Lot 1 of the proposed subdivision would result in a total of 5 lots accessing off of the easement, which would not exceed the maximum number of 5 lots that were permitted to access off the easement permitted under the Dal pay Estates Division 2 Short Plat. Hexrpt 07~119.doc City of Renton P/8/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 7 of 9 The existing 20-foot wide access easement off of Redmond Court NE was approved as a part of the Veldyke/Webber Short Plat (LUA05-065) to provide access to a maximum of two lots (one of which being Lot 5 of the Veldyke/Webber Short Plat), Therefore, the proposal to provide access to three additional lots (Lots 2-4) proposed to be created under the current subdivision would exceed the maximum number of lots approved to take access off of the existing 20-foot wide easement. In order to provide access to three additional lots, the easement would need to be widened to 26 feet with 20 feet of paving or a Modification to the City's Street Standards would need to be granted. Staff recommends as a condition of approval that a revised plat map be submitted prior to final plat approval widening the existing access easement proposed to provide access to Lots 2-4 to 26 feet with 20 feet of paving or that a Modification to the City's Street Standards be requested and granted by the Development Engineering Supervisor, To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Traffic Mitigation Fee. The Traffic Mitigation Fee is based on $75 per net new average daily trip attributed to the proposed subdivision, The proposed 4 new residential lots would be expected to generate approximately 38.28 new average weekday trips (4 new homes x 9.57 trips per home= 38,28), The fee for the proposed plat is estimated to be $2,871 (38.28 total trips x $75.00 = $2,871) and is payable prior to the recording of the plat. Topography and Vegetation: The topography across proposed Lot 1 is relatively flat with a gradual slope towards the protected slope areas located within the proposed NGPE. The topography across Lots 2-4 slopes to the southwest at an average grade of 11 percent. In addition, the topography across the central portion of the site slopes down to a ravine with grades in excess of 40 percent. With the project application, the applicant submitted a Geotechnical Report prepared by Dennis Joule, dated January 16, 2004. The Environmental Review Committee adopted the recommendations found in the submitted geotechnical report as mitigation. A Stream Study prepared by Alder NW, dated November 19, 2007 was submitted for the proposed project. A stream was identified within the ravine located on the central portion of the project site. The stream was classified as an intermittent Class 4 stream. A Class 4 stream requires a 35-foot stream buffer; however the City's Critical Areas Regulations require that when a stream buffer falls within a protected slope, the buffer shall extend to the top of the slope. According to the submitted stream study, portions of the 35-foot required stream buffer falls within the protected slope; therefore where the stream buffer falls within the protected slope area, the buffer extends to the top of the protected slope. No development is proposed within the protected slope or the stream buffer area. To protect the critical areas located on the project site, staff recommends as a condition of approval that a Native Growth Protection Easement shall be recorded over the protected slopes, Class 4 stream, and associated buffer area (Tract A) prior to or concurrent with the recording of the final plat map. To notify future residents of the Dalpay Preliminary Plat Phase Ill of the presence of the critical areas, staff recommends as a condition of approval that the edge of the protected slopes, Class 4 stream, and associated buffer be delineated with a split rail fence and identified with signage as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of Utility Construction Permit Application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The project site is currently forested with a variety of trees, shrubs, and ground cover. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made to preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. A significant tree retention plan was submitted with the project application. According to a tree retention plan that was submitted by the applicant, a total of 96 significant trees are located on-site outside of the NGPE, of those 24 would be required to be retained or replaced. The tree retention plan identifies 44 significant trees that are proposed to be retained, which would comply with the retention requirements. To ensure that none of the trees proposed to be retained are damaged during construction, staff recommends as a condition of approval that the trees proposed to be retained are shown on each of the plans submitted as a part of the Utility Construction Permit Application and that protection measures for the trees to ensure survival during construction of the project be submitted for review and approval by the Development Services Division project manager. Hexrpt 07-119.doc City of Renton P/8/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page Bo/9 Temporary Erosion and Sediment Control Plan (TESCP) and the use of Best Management Practices would serve to mitigate potential erosion and off-site sedimentation impacts. The project application includes a Construction Mitigation Plan, which is subject to final approval prior to the issuance of construction permits for the project. Due to the potential for erosion to occur from the project site during construction, the Environmental Review Committee adopted a mitigation measure requiring that erosion control be installed in accordance with the 2005 Department of Ecology Stormwater Management Manual. Relationship to Existing Uses: Single family residential homes surround the subject site. The proposed detached single family residences would be compatible with the surrounding development. D. Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. These fees paid would help offset any additional impacts to emergency services generated from this development. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Fire Mitigation Fee. The Fire Mitigation Fee is based on a rate of $488.00 per new single family lot. The fee is estimated at $1,952.00 ($488 x 4 = $1,952.00) and is payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling. Based on the student generation factor, the proposed plat would potentially result in 2 additional students (0.44 X 4 = 1.76). Storm Drainage/Surface Water: A Technical Information Report prepared by Cramer Northwest, Inc., dated August 13 2007 was submitted with the application materials. According to the report the existing drainage currently sheet flows to the ravine located on the central portion of the project site, where it becomes a small stream, which flows towards NE Sunset Blvd. The submitted report concludes that the proposed project is exempt from detention and water quality improvements per the 1990 King County Surface Water Design Manual. Due to potential downstream drainage problems, the City's Environmental Review Committee imposed a SEPA mitigation measure that requires the project to comply with the 2005 King County Surface Water Design Manual. Applicant will be required to tightline all roof downspout systems and footing drains to a storm system. A geotechnical report dated January 16, 2004 was submitted. A revised report shall be required with the Utility Construction Permit submitted as the report recommends that the roof and footing drains be tied into the neighboring storm vault being built by the Veldyke/Webber Short Plat. It is not clear if this in option or if both parties have agreed to this. The Surface Water System Development Charges are based on a rate of $759.00 x 4 single-family homes. The estimated fees based on the proposed plat are $3,036.00. Payment of these fees will be required prior to issuance of utility construction permit. Water and Sanitary Sewer Utilities: The subject site is located within the City of Renton water service area. An 8-inch water main will be extended to the east property line within a 26-foot utility and access easement provided by the Veldyke/Webber Short Plat. An 8-inch sewer main is being extended from NE 191 " internally into the short plat. Available fire flow from the dead end main will be 1,250 gpm. The proposed project is located in the 300 Water Pressure Zone and is outside an Aquifer Protection Zone. Static pressure in the area is approximately 80 psi. Fire flow requirement for single-family residences under 3,600 square feet, including garage is 1,000 gpm. Hydrants are required within 300 feet of all structures. Existing hydrants to be counted as fire protection will be required to be retrofitted with a 5-inch storz quick disconnect fitting. Additional fire flow and hydrants are required if the total square footage of the new single-family structures are greater than 3600 square feet. Lots 2, 3, and 4 will require residential fire sprinkler systems. A minimum of a one inch domestic water meter will be required.

The project site is located south of NE 19th Street and west of Redmond Court NE and is zoned Residential -8 (R-8) dwelling units per acre. The proposed lot sizes are as follows: Lot 1 is 8,140 square feet, Lot 2 is 12,985 square feet, Lot 3 is 12,879 square feet, and Lot 4 is 7,462 square feet. Protected slopes and an unnamed stream are located on the central portion of the project site and would be protected within an NGPE. No development is proposed on the protected slopes or within 30 feet of the stream. The grading would be limited to the construction of the proposed private street and utilities. Approximately 200- 300 cubic yards of grading is proposed. Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 would be provided via a private street off of Redmond Court NE. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21C, 1971 as amended), on November 5, 2007, the Environmental Review Committee issued a Determination of Non-Significance -Mitigated Hexrpt 07-1 i 9.doc City of Renton P/B/PW Department DALPA Y PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 4 of9 (DNS-M) for the Dalpay Preliminary Plat Phase Ill. The DNS-M included 6 mitigation measures. A 14-day appeal period commenced on November 13, 2007 and ends on November 27, 2007. As of the composition of this report no appeals of the threshold determination have been filed. 3. COMPLIANCE WITH ERC MITIGATION MEASURES 1. The construction of new single family residences shall maintain a 25-foot buffer from the edge of the protected slope, unless based on appropriate subsurface exploration and slope stability analysis a geotechnical engineer concludes that the 25-foot buffer may be reduced. 2. The applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed pursuant to the Department of Ecology's Erosion and Sediment Control Requirements outlined in Volume II of the 2005 Stormwater Management Manual and provide staff with a Construction Mitigation Plan prior to issuance of Construction Permits. This condition shall be subject to the review and approval of the Development Services Division. 3. The storm drainage system for this project shall be required to comply with the requirements found in the 2005 King County Surface Water Design Manual. 4. The applicant shall pay a Parks Mitigation Fee based on $530.76 per each new single family lot. The fee is estimated at $2,123.04. 5. The applicant shall pay a Traffic Mitigation Fee in the amount of $75 for each new net daily trip prior to the recording of the final plat. It is anticipated that the proposed project would result in the payment of $2,871.00. 6. The applicant shall pay a Fire Mitigation Fee based on $488.00 per new single family lot prior to the recording of the final plat. The fee is estimated at $1,952. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. Lands in the RSF designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies: Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. The proposal project for four lots would arrive at a net density of 4.25 dwelling units per net acre on the project site, which is within the density range required. The proposal to re-subdivide the Dalpay Estates Division 2 parent parcel into a total of 8 lots would arrive at a net density of 4.5 dwelling units per net acre, which is within the density range required. Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of less than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on lot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation, but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Hexrpt 07-119.doc ' City of Renton P/8/PW Department DALPAY PRELIMINARY PLAT PHASE Ill Preliminar; Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page 5of9 All of the proposed lots equal or exceed the minimum lot size of 5,000 square feet. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. The proposed new lots would meet the required lot size, width, and setbacks area. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of life for existing residents. The proposed lots are oriented such that all of the lots would have access to a public right-of-way. Approval of this application would not decrease the quality of life for residents in the immediate vicinity. Policy CD-12. Infill development, defined as new short plats of nine or fewer lots, should be encouraged in order to add variety, updated housing stock, and new vitality to neighborhoods. The proposed short plat would subdivide one existing parcel into four lots. Four new residences would be constructed on the new lots, updating the housing stock in the existing neighborhood. B. Compliance with the Underlying Zoning Designation. The 1.66-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of 4 new single-family residential units. Density-The R-8 zone requires a minimum density of 4.0 dwelling units per net acre (dulac) and permits a maximum density of 8.0 dwelling units per net acre. Net density is calculated after public rights-of-way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 520 square feet of private streets, and 30,866 square feet of critical areas, the proposal for 4 lots would result in a net density of 4.25 dwelling units per acre (4 lots / 0.94 acres = 4.25 du/ac). In addition, staff reviewed the proposed subdivision in the context of the previously approved Dalpay Estates Division 2 Short Plat. The proposal to subdivide the parent Dalpay Estates Division 2 parcel into 8 lots would result in a density of 4.5 dwelling units per acre. The proposed subdivision would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone is 5,000 sq ft for parcels that total less than 1 acre in net area. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. The proposed plat would create four lots, Lot 1 would have a lot area of 8,140 square feet, Lot 2 would have a lot area of 12,985 square feet, Lot 3 would have a lot area of 10,929 square feet, and Lot 4 would have a lot area of 7,462 square feet. All of the lots would be interior lots as none of the lots abut a public street. The proposed lots would have lot widths ranging from 67 feet to 90 feet. The proposed lots would have lot depths ranging from 84 feet to 223 feet. As proposed the new lots would comply with the City's minimum lot size, width and depth requirements. Setbacks -In the R-8 zone, the minimum front and side yard along street setbacks are 15 feet for the primary residence and 20 feet for an attached garage, the minimum interior side yard setback is 5 feet and the minimum rear yard setback is 20 feet. The proposed lots appear to contain adequate area to provide for the construction of single family residences after the consideration of the setback requirements. Compliance with these setback standards will be verified prior to the issuance of individual building permits. Building Standards -The R-8 zone permits one single family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 sq ft each, or one per lot at 1,000 sq ft in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is 35% or 2,500 square feet, whichever is greater. Hexrpt 07-119.doc City of Renton P/8/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DATE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 6af9 The proposal's compliance with these building standards would be verified prior to the issuance of individual building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping -The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum amount of landscaping required for sites abutting a non-arterial public street is 5 feet provided that if there is additional undeveloped right-of-way in excess of 5 feet, this shall also be landscaped. A determination has been made that if no additional area is available within the public right- of-way due to required improvements, the 5-foot landscaped strip may be located within private property abutting the public right-of-way. The project site does not abut any public street frontages; therefore the 5- foot landscape strip is not required. Two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer) are required to be planted within the 15-foot front yard setback area for the proposed lots. A conceptual landscape plan was submitted with the project application. The landscape plan proposes to plant two Autumn Brilliance Serviceberry trees within the front yard areas of Lot 3 and 4. A total of 4 evergreen trees are proposed to be retained and one 6-7-foot tall Shore Pine is proposed to be planted within the 15-foot front yard area of proposed Lot 2. The submitted plan did not include any trees within the front yard area of proposed Lot 1. The landscape plan shall be revised to include two trees within the front yard area of proposed Lot 1. Staff recommends as a condition of approval that a revised landscape plan be submitted prior to the approval of the final plat showing two trees within the 15-foot front yard area of proposed Lot 1. The revised landscape plan shall be submitted to the Development Services Division project manager for review and approval. The applicant will be required to submit a detailed landscaping plan to the Development Services Division for review and approval prior to the issuance of a building permit. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. As proposed, the lots appear to comply with arrangement and access requirements of the Subdivision Regulations. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. Proposed Lot 1 would be oriented to provide its front yard facing to the north, Lot 2 would be oriented to provide its front yard facing to the south, and Lots 3 and 4 would be oriented to provide their front yards facing to the north. Staff recommends as a condition of approval that a note be placed on the face of the final plat map identifying the orientation of the front yards of each of the new lots. Each of the lots would satisfy the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: There are no property corners at intersections. Access and Street Improvements: Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 is proposed via a 20-foot wide private access street off of Redmond Court NE. Private streets are permitted to serve a maximum of 6 lots provided a minimum of two lots abut a public right-of-way. A joint use driveway is permitted to provide access to a maximum of two lots and is required to have a minimum easement width of 20 feet. The existing 20-foot wide access easement off of NE 19th Street currently is approved to provide access to Lots 1-5 of the Dalpay Estates Division 2 Short Plat that was previously approved. The current project is a re-subdivision of Lot 5 of the Dalpay Estates Division 2 Short Plat. The proposal to provide access to Lot 1 of the proposed subdivision would result in a total of 5 lots accessing off of the easement, which would not exceed the maximum number of 5 lots that were permitted to access off the easement permitted under the Dalpay Estates Division 2 Short Plat. Hexrpt 07·119.doc City of Renton P/B/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 7 of 9 The existing 20-foot wide access easement off of Redmond Court NE was approved as a part of the Veldyke/Webber Short Plat (LUAOS-065) to provide access to a maximum of two lots (one of which being Lot 5 of the Veldyke/Webber Short Plat). Therefore, the proposal to provide access to three additional lots (Lots 2-4) proposed to be created under the current subdivision would exceed the maximum number of lots approved to take access off of the existing 20-foot wide easement. In order to provide access to three additional lots, the easement would need to be widened to 26 feet with 20 feet of paving or a Modification to the City's Street Standards would need to be granted. Staff recommends as a condition of approval that a revised plat map be submitted prior to final plat approval widening the existing access easement proposed to provide access to Lots 2-4 to 26 feet with 20 feet of paving or that a Modification to the City's Street Standards be requested and granted by the Development Engineering Supervisor. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Traffic Mitigation Fee. The Traffic Mitigation Fee is based on $75 per net new average daily trip attributed to the proposed subdivision. The proposed 4 new residential lots would be expected to generate approximately 38.28 new average weekday trips (4 new homes x 9.57 trips per home = 38.28). The fee for the proposed plat is estimated to be $2,871 (38.28 total trips x $75.00 = $2,871) and is payable prior to the recording of the plat. Topography and Vegetation: The topography across proposed Lot 1 is relatively flat with a gradual slope towards the protected slope areas located within the proposed NGPE. The topography across Lots 2-4 slopes to the southwest at an average grade of 11 percent. In addition, the topography across the central portion of the site slopes down to a ravine with grades in excess of 40 percent. With the project application, the applicant submitted a Geotechnical Report prepared by Dennis Joule, dated January 16, 2004. The Environmental Review Committee adopted the recommendations found in the submitted geotechnical report as mitigation. A Stream Study prepared by Alder NW, dated November 19, 2007 was submitted for the proposed project. A stream was identified within the ravine located on the central portion of the project site. The stream was classified as an intermittent Class 4 stream. A Class 4 stream requires a 35-foot stream buffer; however the City's Critical Areas Regulations require that when a stream buffer falls within a protected slope, the buffer shall extend to the top of the slope. According to the submitted stream study, portions of the 35-foot required stream buffer falls within the protected slope; therefore where the stream buffer falls within the protected slope area, the buffer extends to the top of the protected slope. No development is proposed within the protected slope or the stream buffer area. To protect the critical areas located on the project site, staff recommends as a condition of approval that a Native Growth Protection Easement shall be recorded over the protected slopes, Class 4 stream, and associated buffer area (Tract A) prior to or concurrent with the recording of the final plat map. To notify future residents of the Dalpay Preliminary Plat Phase Ill of the presence of the critical areas, staff recommends as a condition of approval that the edge of the protected slopes, Class 4 stream, and associated buffer be delineated with a split rail fence and identified with signage as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of Utility Construction Permit Application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The project site is currently forested with a variety of trees, shrubs, and ground cover. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made to preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. A significant tree retention plan was submitted with the project application. According to a tree retention plan that was submitted by the applicant, a total of 96 significant trees are located on-site outside of the NGPE, of those 24 would be required to be retained or replaced. The tree retention plan identifies 44 significant trees that are proposed to be retained, which would comply with the retention requirements. To ensure that none of the trees proposed to be retained are damaged during construction, staff recommends as a condition of approval that the trees proposed to be retained are shown on each of the plans submitted as a part of the Utility Construction Permit Application and that protection measures for the trees to ensure survival during construction of the project be submitted for review and approval by the Development Services Division project manager. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 8of9 Temporary Erosion and Sediment Control Plan (TESCP) and the use of Best Management Practices would serve to mitigate potential erosion and off-site sedimentation impacts. The project application includes a Construction Mitigation Plan, which is subject to final approval prior to the issuance of construction permits for the project. Due to the potential for erosion to occur from the project site during construction, the Environmental Review Committee adopted a mitigation measure requiring that erosion control be installed in accordance with the 2005 Department of Ecology Stormwater Management Manual. Relationship to Existing Uses: Single family residential homes surround the subject site. The proposed detached single family residences would be compatible with the surrounding development. D. Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. These fees paid would help offset any additional impacts to emergency services generated from this development. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Fire Mitigation Fee. The Fire Mitigation Fee is based on a rate of $488.00 per new single family lot. The fee is estimated at $1,952.00 ($488 x 4 = $1,952.00) and is payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling. Based on the student generation factor, the proposed plat would potentially result in 2 additional students (0.44 X 4 = 1.76). Storm Drainage/Surface Water: A Technical Information Report prepared by Cramer Northwest, Inc., dated August 13 2007 was submitted with the application materials. According to the report the existing drainage currently sheet flows to the ravine located on the central portion of the project site, where it becomes a small stream, which flows towards NE Sunset Blvd. The submitted report concludes that the proposed project is exempt from detention and water quality improvements per the 1990 King County Surface Water Design Manual. Due to potential downstream drainage problems, the City's Environmental Review Committee imposed a SEPA mitigation measure that requires the project to comply with the 2005 King County Surface Water Design Manual. Applicant will be required to tightline all roof downspout systems and footing drains to a storm system. A geotechnical report dated January 16, 2004 was submitted. A revised report shall be required with the Utility Construction Permit submitted as the report recommends that the roof and footing drains be tied into the neighboring storm vault being built by the Veldyke/Webber Short Plat. It is not clear if this in option or if both parties have agreed to this. The Surface Water System Development Charges are based on a rate of $759.00 x 4 single-family homes. The estimated fees based on the proposed plat are $3,036.00. Payment of these fees will be required prior to issuance of utility construction permit. Water and Sanitary Sewer Utilities: The subject site is located within the City of Renton water service area. An 8-inch water main will be extended to the east property line within a 26-foot utility and access easement provided by the Veldyke/Webber Short Plat. An 8-inch sewer main is being extended from NE 19th internally into the short plat. Available fire flow from the dead end main will be 1,250 gpm. The proposed project is located in the 300 Water Pressure Zone and is outside an Aquifer Protection Zone. Static pressure in the area is approximately 80 psi. Fire flow requirement for single-family residences under 3,600 square feet, including garage is 1,000 gpm. Hydrants are required within 300 feet of all structures. Existing hydrants to be counted as fire protection will be required to be retrofitted with a 5-inch storz quick disconnect fitting. Additional fire flow and hydrants are required if the total square footage of the new single-family structures are greater than 3600 square feet. Lots 2, 3, and 4 will require residential fire sprinkler systems. A minimum of a one inch domestic water meter will be required.

All short plats shall provide separate water services to each building lot prior to recording of the short plat. Separate permits and fees for water meters will be required. Water System Development Charges are based on a rate of $1,956.00 x 4 new single-family homes. The estimated fees based on the proposed plat layout are $7,824.00. Payment of these fees will be required prior to issuance of utility construction permit. The subject property is served by City of Renton sewer service. An 8-inch sewer main will be extended to the east property line within a utility and access easement provided by the Veldyke/Webber Short Plat. The Veldyke/Webber Short Plat is extending an 8-inch sewer main from NE 191 " internally into the short plat. A separate side sewer stub to each new lot is required prior to the recording of the plat, the minimum slope shall be 2 percent. Sanitary Sewer System Development Charges are based on a rate of $1,017.00 x 4 new single-family homes. The estimated fees based on the proposed plat layout are $4,068.00. Credit is given to the existing homes connected to sewer. Payment of these fees will be required prior to issuance of utility construction permit. This site is subject to the Honey Creek Special Assessment District. Charges are based on a rate of $250.00 x 4. Fees based on the site plan are $1,000.00. Payment of these fees will be required prior to issuance of issuance of the utility construction permit. H.

The project site is located south of NE 19th Street and west of Redmond Court NE and is zoned Residential -8 (R-8) dwelling units per acre. The proposed lot sizes are as follows: Lot 1 is 8,140 square feet, Lot 2 is 12,985 square feet. Lot 3 is 12,879 square feet, and Lot 4 is 7,462 square feet. Protected slopes and an unnamed stream are located on the central portion of the project site and would be protected within an NGPE. No development is proposed on the protected slopes or within 30 feet of the stream. The grading would be limited to the construction of the proposed private street and utilities. Approximately 200- 300 cubic yards of grading is proposed. Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 would be provided via a private street off of Redmond Court NE. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21C, 1971 as amended), on November 5, 2007, the Environmental Review Committee issued a Determination of Non-Significance -Mitigated Hexrpt 07-119.doc City of Renton PIB/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 4 of 9 (DNS-M) for the Dalpay Preliminary Plat Phase Ill. The DNS-M included 6 mitigation measures. A 14-day appeal period commenced on November 13, 2007 and ends on November 27, 2007. As of the composition of this report no appeals of the threshold determination have been filed. 3. COMPLIANCE WITH ERC MITIGATION MEASURES 1. The construction of new single family residences shall maintain a 25-foot buffer from the edge of the protected slope, unless based on appropriate subsurface exploration and slope stability analysis a geotechnical engineer concludes that the 25-foot buffer may be reduced. 2. The applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed pursuant to the Department of Ecology's Erosion and Sediment Control Requirements outlined in Volume II of the 2005 Stormwater Management Manual and provide staff with a Construction Mitigation Plan prior to issuance of Construction Permits. This condition shall be subject to the review and approval of the Development Services Division. 3. The storm drainage system for this project shall be required to comply with the requirements found in the 2005 King County Surface Water Design Manual. 4. The applicant shall pay a Parks Mitigation Fee based on $530. 76 per each new single family lot. The fee is estimated at $2,123.04. 5. The applicant shall pay a Traffic Mitigation Fee in the amount of $75 for each new net daily trip prior to the recording of the final plat. It is anticipated that the proposed project would result in the payment of $2,871.00. 6. The applicant shall pay a Fire Mitigation Fee based on $488.00 per new single family lot prior to the recording of the final plat. The fee is estimated at $1,952. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. Lands in the RSF designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies: Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. The proposal project for four lots would arrive at a net density of 4.25 dwelling units per net acre on the project site, which is within the density range required. The proposal to re-subdivide the Dalpay Estates Division 2 parent parcel into a total of 8 lots would arrive at a net density of 4.5 dwelling units per net acre, which is within the density range required. Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of less than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on lot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation, but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Hexrpt 07-119.doc , City of Renton P/BIPW Department DALPAY PRELIMINARY PLAT PHASE Ill Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page 5 of 9 All of the proposed lots equal or exceed the minimum lot size of 5,000 square feet. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. The proposed new lots would meet the required lot size, width, and setbacks area. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of life for existing residents. The proposed lots are oriented such that all of the lots would have access to a public right-of-way. Approval of this application would not decrease the quality of life for residents in the immediate vicinity. Policy CD-12. Infill development, defined as new short plats of nine or fewer lots, should be encouraged in order to add variety, updated housing stock, and new vitality to neighborhoods. The proposed short plat would subdivide one existing parcel into four lots. Four new residences would be constructed on the new lots, updating the housing stock in the existing neighborhood. B. Compliance with the Underlying Zoning Designation. The 1.66-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of 4 new single-family residential units. Density The R-8 zone requires a minimum density of 4.0 dwelling units per net acre (dulac) and permits a maximum density of 8.0 dwelling units per net acre. Net density is calculated after public rights-of-way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 520 square feet of private streets, and 30,866 square feet of critical areas, the proposal for 4 lots would result in a net density of 4.25 dwelling units per acre (4 lots I 0.94 acres = 4.25 du/ac). In addition, staff reviewed the proposed subdivision in the context of the previously approved Dalpay Estates Division 2 Short Plat. The proposal to subdivide the parent Dalpay Estates Division 2 parcel into 8 lots would result in a density of 4.5 dwelling units per acre. The proposed subdivision would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone is 5,000 sq ft for parcels that total less than 1 acre in net area. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. The proposed plat would create four lots, Lot 1 would have a lot area of 8,140 square feet, Lot 2 would have a lot area of 12,985 square feet, Lot 3 would have a lot area of 10,929 square feet, and Lot 4 would have a lot area of 7,462 square feet. All of the lots would be interior lots as none of the lots abut a public street. The proposed lots would have lot widths ranging from 67 feet to 90 feet. The proposed lots would have lot depths ranging from 84 feet to 223 feet. As proposed the new lots would comply with the City's minimum lot size, width and depth requirements. Setbacks -In the R-8 zone, the minimum front and side yard along street setbacks are 15 feet for the primary residence and 20 feet for an attached garage, the minimum interior side yard setback is 5 feet and the minimum rear yard setback is 20 feet. The proposed lots appear to contain adequate area to provide for the construction of single family residences after the consideration of the setback requirements. Compliance with these setback standards will be verified prior to the issuance of individual building permits. Building Standards -The R-8 zone permits one single family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 sq ft each, or one per lot at 1,000 sq ft in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is 35% or 2,500 square feet, whichever is greater. Hexrpt 07~119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 6 of9 The proposal's compliance with these building standards would be verified prior to the issuance of individual building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping -The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum amount of landscaping required for sites abutting a non-arterial public street is 5 feet provided that if there is additional undeveloped right-of-way in excess of 5 feet, this shall also be landscaped. A determination has been made that if no additional area is available within the public right- of-way due to required improvements, the 5-foot landscaped strip may be located within private property abutting the public right-of-way. The project site does not abut any public street frontages; therefore the 5- foot landscape strip is not required. Two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer) are required to be planted within the 15-foot front yard setback area for the proposed lots. A conceptual landscape plan was submitted with the project application. The landscape plan proposes to plant two Autumn Brilliance Serviceberry trees within the front yard areas of Lot 3 and 4. A total of 4 evergreen trees are proposed to be retained and one 6-7-foot tall Shore Pine is proposed to be planted within the 15-foot front yard area of proposed Lot 2. The submitted plan did not include any trees within the front yard area of proposed Lot 1. The landscape plan shall be revised to include two trees within the front yard area of proposed Lot 1. Staff recommends as a condition of approval that a revised landscape plan be submitted prior to the approval of the final plat showing two trees within the 15-foot front yard area of proposed Lot 1. The revised landscape plan shall be submitted to the Development Services Division project manager for review and approval. The applicant will be required to submit a detailed landscaping plan to the Development Services Division for review and approval prior to the issuance of a building permit. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. As proposed, the lots appear to comply with arrangement and access requirements of the Subdivision Regulations. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. Proposed Lot 1 would be oriented to provide its front yard facing to the north, Lot 2 would be oriented to provide its front yard facing to the south, and Lots 3 and 4 would be oriented to provide their front yards facing to the north. Staff recommends as a condition of approval that a note be placed on the face of the final plat map identifying the orientation of the front yards of each of the new lots. Each of the lots would satisfy the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: There are no property corners at intersections. Access and Street Improvements: Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 is proposed via a 20-foot wide private access street off of Redmond Court NE. Private streets are permitted to serve a maximum of 6 lots provided a minimum of two lots abut a public right-of-way. A joint use driveway is permitted to provide access to a maximum of two lots and is required to have a minimum easement width of 20 feet. The existing 20-foot wide access easement off of NE 19th Street currently is approved to provide access to Lots 1-5 of the Dal pay Estates Division 2 Short Plat that was previously approved. The current project is a re-subdivision of Lot 5 of the Dalpay Estates Division 2 Short Plat. The proposal to provide access to Lot 1 of the proposed subdivision would result in a total of 5 lots accessing off of the easement, which would not exceed the maximum number of 5 lots that were permitted to access off the easement permitted under the Dal pay Estates Division 2 Short Plat. Hexrpt 07-119.doc ' City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 7 of 9 The existing 20-foot wide access easement off of Redmond Court NE was approved as a part of the Veldyke/Webber Short Plat (LUA05-065) to provide access to a maximum of two lots (one of which being Lot 5 of the Veldyke/Webber Short Plat). Therefore, the proposal to provide access to three additional lots (Lots 2-4) proposed to be created under the current subdivision would exceed the maximum number of lots approved to take access off of the existing 20-foot wide easement. In order to provide access to three additional lots, the easement would need to be widened to 26 feet with 20 feet of paving or a Modification to the City's Street Standards would need to be granted. Staff recommends as a condition of approval that a revised plat map be submitted prior to final plat approval widening the existing access easement proposed to provide access to Lots 2-4 to 26 feet with 20 feet of paving or that a Modification to the City's Street Standards be requested and granted by the Development Engineering Supervisor. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Traffic Mitigation Fee. The Traffic Mitigation Fee is based on $75 per net new average daily trip attributed to the proposed subdivision. The proposed 4 new residential lots would be expected to generate approximately 38.28 new average weekday trips (4 new homes x 9.57 trips per home = 38.28). The fee for the proposed plat is estimated to be $2,871 (38.28 total trips x $75.00 = $2,871) and is payable prior to the recording of the plat. Topography and Vegetation: The topography across proposed Lot 1 is relatively flat with a gradual slope towards the protected slope areas located within the proposed NGPE. The topography across Lots 2-4 slopes to the southwest at an average grade of 11 percent. In addition, the topography across the central portion of the site slopes down to a ravine with grades in excess of 40 percent. With the project application, the applicant submitted a Geotechnical Report prepared by Dennis Joule, dated January 16, 2004. The Environmental Review Committee adopted the recommendations found in the submitted geotechnical report as mitigation. A Stream Study prepared by Alder NW, dated November 19, 2007 was submitted for the proposed project. A stream was identified within the ravine located on the central portion of the project site. The stream was classified as an intermittent Class 4 stream. A Class 4 stream requires a 35-foot stream buffer; however the City's Critical Areas Regulations require that when a stream buffer falls within a protected slope, the buffer shall extend to the top of the slope. According to the submitted stream study, portions of the 35-foot required stream buffer falls within the protected slope; therefore where the stream buffer falls within the protected slope area, the buffer extends to the top of the protected slope. No development is proposed within the protected slope or the stream buffer area. To protect the critical areas located on the project site, staff recommends as a condition of approval that a Native Growth Protection Easement shall be recorded over the protected slopes, Class 4 stream, and associated buffer area (Tract A) prior to or concurrent with the recording of the final plat map. To notify future residents of the Dalpay Preliminary Plat Phase 111 of the presence of the critical areas, staff recommends as a condition of approval that the edge of the protected slopes, Class 4 stream, and associated buffer be delineated with a split rail fence and identified with signage as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of Utility Construction Permit Application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The project site is currently forested with a variety of trees, shrubs, and ground cover. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made to preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. A significant tree retention plan was submitted with the project application. According to a tree retention plan that was submitted by the applicant, a total of 96 significant trees are located on-site outside of the NGPE, of those 24 would be required to be retained or replaced. The tree retention plan identifies 44 significant trees that are proposed to be retained, which would comply with the retention requirements. To ensure that none of the trees proposed to be retained are damaged during construction, staff recommends as a condition of approval that the trees proposed to be retained are shown on each of the plans submitted as a part of the Utility Construction Permit Application and that protection measures for the trees to ensure survival during construction of the project be submitted for review and approval by the Development Services Division project manager. Hexrpt 07-119.doc City of Renton P/8/PW Department DALPA Y PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 8of9 Temporary Erosion and Sediment Control Plan (TESCP) and the use of Best Management Practices would serve to mitigate potential erosion and off-site sedimentation impacts. The project application includes a Construction Mitigation Plan, which is subject to final approval prior to the issuance of construction permits for the project. Due to the potential for erosion to occur from the project site during construction, the Environmental Review Committee adopted a mitigation measure requiring that erosion control be installed in accordance with the 2005 Department of Ecology Stormwater Management Manual. Relationship to Existing Uses: Single family residential homes surround the subject site. The proposed detached single family residences would be compatible with the surrounding development. D. Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention stall indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. These fees paid would help offset any additional impacts to emergency services generated from this development. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Fire Mitigation Fee. The Fire Mitigation Fee is based on a rate of $488.00 per new single family lot. The fee is estimated at $1,952.00 ($488 x 4 = $1,952.00) and is payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling. Based on the student generation factor, the proposed plat would potentially result in 2 additional students (0.44 X 4 = 1.76). Storm Drainage/Surface Water: A Technical Information Report prepared by Cramer Northwest, Inc., dated August 13 2007 was submitted with the application materials. According to the report the existing drainage currently sheet flows to the ravine located on the central portion of the project site, where it becomes a small stream, which flows towards NE Sunset Blvd. The submitted report concludes that the proposed project is exempt from detention and water quality improvements per the 1990 King County Surface Water Design Manual. Due to potential downstream drainage problems, the City's Environmental Review Committee imposed a SEPA mitigation measure that requires the project to comply with the 2005 King County Surface Water Design Manual. Applicant will be required to tightline all roof downspout systems and footing drains to a storm system. A geotechnical report dated January 16, 2004 was submitted. A revised report shall be required with the Utility Construction Permit submitted as the report recommends that the roof and footing drains be tied into the neighboring storm vault being built by the Veldyke/Webber Short Plat. It is not clear if this in option or if both parties have agreed to this. The Surface Water System Development Charges are based on a rate of $759.00 x 4 single-family homes. The estimated fees based on the proposed plat are $3,036.00. Payment of these fees will be required prior to issuance of utility construction permit. Water and Sanitary Sewer Utilities: The subject site is located within the City of Renton water service area. An 8-inch water main will be extended to the east property line within a 26-foot utility and access easement provided by the Veldyke/Webber Short Plat. An 8-inch sewer main is being extended from NE 19'" internally into the short plat. Available fire flow from the dead end main will be 1,250 gpm. The proposed project is located in the 300 Water Pressure Zone and is outside an Aquifer Protection Zone. Static pressure in the area is approximately 80 psi. Fire flow requirement for single-family residences under 3,600 square feet, including garage is 1,000 gpm. Hydrants are required within 300 feet of all structures. Existing hydrants to be counted as fire protection will be required to be retrofitted with a 5-inch storz quick disconnect fitting. Additional fire flow and hydrants are required if the total square footage of the new single-family structures are greater than 3600 square feet. Lots 2, 3, and 4 will require residential fire sprinkler systems. A minimum of a one inch domestic water meter will be required.

The project site is located south of NE 1 g" Street and west of Redmond Court NE and is zoned Residential -8 (R-8) dwelling units per acre. The proposed lot sizes are as follows: Lot 1 is 8,140 square feet, Lot 2 is 12,985 square feet, Lot 3 is 12,879 square feet, and Lot 4 is 7,462 square feet. Protected slopes and an unnamed stream are located on the central portion of the project site and would be protected within an NGPE. No development is proposed on the protected slopes or within 30 feet of the stream. The grading would be limited to the construction of the proposed private street and utilities. Approximately 200- 300 cubic yards of grading is proposed. Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 would be provided via a private street off of Redmond Court NE. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21 C, 1971 as amended), on November 5, 2007, the Environmental Review Committee issued a Determination of Non-Significance -Mitigated Hexrpt 07-119.doc City of Renton P/8/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 4 of9 (DNS-M) for the Dalpay Preliminary Plat Phase Ill. The DNS-M included 6 mitigation measures. A 14-day appeal period commenced on November 13, 2007 and ends on November 27, 2007. As of the composition of this report no appeals of the threshold determination have been filed. 3. COMPLIANCE WITH ERC MITIGATION MEASURES 1. The construction of new single family residences shall maintain a 25-foot buffer from the edge of the protected slope, unless based on appropriate subsurface exploration and slope stability analysis a geotechnical engineer concludes that the 25-foot buffer may be reduced. 2. The applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed pursuant to the Department of Ecology's Erosion and Sediment Control Requirements outlined in Volume II of the 2005 Stormwater Management Manual and provide staff with a Construction Mitigation Plan prior to issuance of Construction Permits. This condition shall be subject to the review and approval of the Development Services Division. 3. The storm drainage system for this project shall be required to comply with the requirements found in the 2005 King County Surface Water Design Manual. 4. The applicant shall pay a Parks Mitigation Fee based on $530.76 per each new single family lot. The fee is estimated at $2,123.04. 5. The applicant shall pay a Traffic Mitigation Fee in the amount of $75 for each new net daily trip prior to the recording of the final plat. It is anticipated that the proposed project would result in the payment of $2,871.00. 6. The applicant shall pay a Fire Mitigation Fee based on $488.00 per new single family lot prior to the recording of the final plat. The fee is estimated at $1,952. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. Lands in the RSF designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies: Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. The proposal project for four lots would arrive at a net density of 4.25 dwelling units per net acre on the project site, which is within the density range required. The proposal to re-subdivide the Dalpay Estates Division 2 parent parcel into a total of 8 lots would arrive at a net density of 4.5 dwelling units per net acre, which is within the density range required. Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of less than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on lot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation, but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Hexrpt 07-119.doc City of Renton P/8/PW Deparlment DALPA Y PRELIMINARY PLAT PHASE Ill Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page 5of9 All of the proposed lots equal or exceed the minimum lot size of 5,000 square feet. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. The proposed new lots would meet the required lot size, width, and setbacks area. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of life for existing residents. The proposed lots are oriented such that all of the lots would have access to a public right-of-way. Approval of this application would not decrease the quality of life for residents in the immediate vicinity. Policy CD-12. Infill development, defined as new short plats of nine or fewer lots, should be encouraged in order to add variety, updated housing stock, and new vitality to neighborhoods. The proposed short plat would subdivide one existing parcel into four lots. Four new residences would be constructed on the new Jots, updating the housing stock in the existing neighborhood. 8. Compliance with the Underlying Zoning Designation. The 1.66-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of 4 new single-family residential units. Density-The R-8 zone requires a minimum density of 4.0 dwelling units per net acre (dulac) and permits a maximum density of 8.0 dwelling units per net acre. Net density is calculated after public rights-of-way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 520 square feet of private streets, and 30,866 square feet of critical areas, the proposal for 4 lots would result in a net density of 4.25 dwelling units per acre (4 lots / 0.94 acres = 4.25 du/ac). In addition, staff reviewed the proposed subdivision in the context of the previously approved Dalpay Estates Division 2 Short Plat. The proposal to subdivide the parent Dalpay Estates Division 2 parcel into 8 lots would result in a density of 4.5 dwelling units per acre. The proposed subdivision would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone is 5,000 sq ft for parcels that total less than 1 acre in net area. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. The proposed plat would create four lots, Lot 1 would have a lot area of 8,140 square feet, Lot 2 would have a lot area of 12,985 square feet, Lot 3 would have a lot area of 10,929 square feet, and Lot 4 would have a lot area of 7,462 square feet. All of the lots would be interior lots as none of the lots abut a public street. The proposed lots would have lot widths ranging from 67 feet to 90 feet. The proposed lots would have lot depths ranging from 84 feet to 223 feet. As proposed the new lots would comply with the City's minimum lot size, width and depth requirements. Setbacks -In the R-8 zone, the minimum front and side yard along street setbacks are 15 feet for the primary residence and 20 feet for an attached garage, the minimum interior side yard setback is 5 feet and the minimum rear yard setback is 20 feet. The proposed lots appear to contain adequate area to provide for the construction of single family residences after the consideration of the setback requirements. Compliance with these setback standards will be verified prior to the issuance of individual building permits. Building Standards -The R-8 zone permits one single family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 sq ft each, or one per lot at 1,000 sq ft in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is 35% or 2,500 square feet, whichever is greater. Hexrpt 07-119.doc City of Renton P/BIPW Department DALPA Y PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 6of9 The proposal's compliance with these building standards would be verified prior to the issuance of individual building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum amount of landscaping required for sites abutting a non-arterial public street is 5 feet provided that if there is additional undeveloped right-of-way in excess of 5 feet, this shall also be landscaped. A determination has been made that if no additional area is available within the public right- of-way due to required improvements, the 5-foot landscaped strip may be located within private property abutting the public right-of-way. The project site does not abut any public street frontages; therefore the 5- foot landscape strip is not required. Two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer) are required to be planted within the 15-foot front yard setback area for the proposed lots. A conceptual landscape plan was submitted with the project application. The landscape plan proposes to plant two Autumn Brilliance Serviceberry trees within the front yard areas of Lot 3 and 4. A total of 4 evergreen trees are proposed to be retained and one 6-7 -foot tall Shore Pine is proposed to be planted within the 15-foot front yard area of proposed Lot 2. The submitted plan did not include any trees within the front yard area of proposed Lot 1. The landscape plan shall be revised to include two trees within the front yard area of proposed Lot 1. Staff recommends as a condition of approval that a revised landscape plan be submitted prior to the approval of the final plat showing two trees within the 15-foot front yard area of proposed Lot 1. The revised landscape plan shall be submitted to the Development Services Division project manager for review and approval. The applicant will be required to submit a detailed landscaping plan to the Development Services Division for review and approval prior to the issuance of a building permit. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. As proposed, the lots appear to comply with arrangement and access requirements of the Subdivision Regulations. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. Proposed Lot 1 would be oriented to provide its front yard facing to the north, Lot 2 would be oriented to provide its front yard facing to the south, and Lots 3 and 4 would be oriented to provide their front yards facing to the north. Staff recommends as a condition of approval that a note be placed on the face of the final plat map identifying the orientation of the front yards of each of the new lots. Each of the lots would satisfy the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: There are no property corners at intersections. Access and Street Improvements: Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 is proposed via a 20-foot wide private access street off of Redmond Court NE. Private streets are permitted to serve a maximum of 6 lots provided a minimum of two lots abut a public right-of-way. A joint use driveway is permitted to provide access to a maximum of two lots and is required to have a minimum easement width of 20 feet. The existing 20-foot wide access easement off of NE 19th Street currently is approved to provide access to Lots 1-5 of the Dalpay Estates Division 2 Short Plat that was previously approved. The current project is a re-subdivision of Lot 5 of the Dalpay Estates Division 2 Short Plat. The proposal to provide access to Lot 1 of the proposed subdivision would result in a total of 5 lots accessing off of the easement, which would not exceed the maximum number of 5 lots that were permitted to access off the easement permitted under the Dalpay Estates Division 2 Short Plat. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY FLAT PHASE iii PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 7 of 9 The existing 20-foot wide access easement off of Redmond Court NE was approved as a part of the Veldyke/Webber Short Plat (LUAOS-065) to provide access to a maximum of two lots (one of which being Lot 5 of the Veldyke/Webber Short Plat). Therefore, the proposal to provide access to three additional lots (Lots 2-4) proposed to be created under the current subdivision would exceed the maximum number of lots approved to take access off of the existing 20-foot wide easement. In order to provide access to three additional lots, the easement would need to be widened to 26 feet with 20 feet of paving or a Modification to the City's Street Standards would need to be granted, Staff recommends as a condition of approval that a revised plat map be submitted prior to final plat approval widening the existing access easement proposed to provide access to Lots 2-4 to 26 feet with 20 feet of paving or that a Modification to the City's Street Standards be requested and granted by the Development Engineering Supervisor. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Traffic Mitigation Fee. The Traffic Mitigation Fee is based on $75 per net new average daily trip attributed to the proposed subdivision. The proposed 4 new residential lots would be expected to generate approximately 38.28 new average weekday trips (4 new homes x 9.57 trips per home = 38.28). The fee for the proposed plat is estimated to be $2,871 (38,28 total trips x $75.00 = $2,871) and is payable prior to the recording of the plat. Topography and Vegetation: The topography across proposed Lot 1 is relatively flat with a gradual slope towards the protected slope areas located within the proposed NGPE. The topography across Lots 2-4 slopes to the southwest at an average grade of 11 percent. In addition, the topography across the central portion of the site slopes down to a ravine with grades in excess of 40 percent. With the project application, the applicant submitted a Geotechnical Report prepared by Dennis Joule, dated January 16, 2004. The Environmental Review Committee adopted the recommendations found in the submitted geotechnical report as mitigation. A Stream Study prepared by Alder NW, dated November 19, 2007 was submitted for the proposed project. A stream was identified within the ravine located on the central portion of the project site. The stream was classified as an intermittent Class 4 stream. A Class 4 stream requires a 35-foot stream buffer; however the City's Critical Areas Regulations require that when a stream buffer falls within a protected slope, the buffer shall extend to the top of the slope. According to the submitted stream study, portions of the 35-foot required stream buffer falls within the protected slope; therefore where the stream buffer falls within the protected slope area, the buffer extends to the top of the protected slope. No development is proposed within the protected slope or the stream buffer area. To protect the critical areas located on the project site, staff recommends as a condition of approval that a Native Growth Protection Easement shall be recorded over the protected slopes, Class 4 stream, and associated buffer area (Tract A) prior to or concurrent with the recording of the final plat map. To notify future residents of the Dalpay Preliminary Plat Phase Ill of the presence of the critical areas, staff recommends as a condition of approval that the edge of the protected slopes, Class 4 stream, and associated buffer be delineated with a split rail fence and identified with signage as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of Utility Construction Permit Application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The project site is currently forested with a variety of trees, shrubs, and ground cover. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made to preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. A significant tree retention plan was submitted with the project application. According to a tree retention plan that was submitted by the applicant, a total of 96 significant trees are located on-site outside of the NGPE, of those 24 would be required to be retained or replaced. The tree retention plan identifies 44 significant trees that are proposed to be retained, which would comply with the retention requirements. To ensure that none of the trees proposed to be retained are damaged during construction, staff recommends as a condition of approval that the trees proposed to be retained are shown on each of the plans submitted as a part of the Utility Construction Permit Application and that protection measures for the trees to ensure survival during construction of the project be submitted for review and approval by the Development Services Division project manager. Hexrpt 07-119.doc City of Renton P/B/PW Department DALPA Y PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page Bof9 Temporary Erosion and Sediment Control Plan (TESCP) and the use of Best Management Practices would serve to mitigate potential erosion and off-site sedimentation impacts. The project application includes a Construction Mitigation Plan, which is subject to final approval prior to the issuance of construction permits for the project. Due to the potential for erosion to occur from the project site during construction, the Environmental Review Committee adopted a mitigation measure requiring that erosion control be installed in accordance with the 2005 Department of Ecology Stormwater Management Manual. Relationship to Existing Uses: Single family residential homes surround the subject site. The proposed detached single family residences would be compatible with the surrounding development. D, Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. These fees paid would help offset any additional impacts to emergency services generated from this development. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Fire Mitigation Fee. The Fire Mitigation Fee is based on a rate of $488.00 per new single family lot. The fee is estimated at $1,952.00 ($488 x 4 = $1,952.00) and is payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling, Based on the student generation factor, the proposed plat would potentially result in 2 additional students (0.44 X 4 = 1.76). Storm Drainage/Surface Water: A Technical Information Report prepared by Cramer Northwest, Inc., dated August 13 2007 was submitted with the application materials. According to the report the existing drainage currently sheet flows to the ravine located on the central portion of the project site, where it becomes a small stream, which flows towards NE Sunset Blvd. The submitted report concludes that the proposed project is exempt from detention and water quality improvements per the 1990 King County Surface Water Design Manual. Due to potential downstream drainage problems, the City's Environmental Review Committee imposed a SEPA mitigation measure that requires the project to comply with the 2005 King County Surface Water Design Manual. Applicant will be required to tightline all roof downspout systems and footing drains to a storm system. A geotechnical report dated January 16, 2004 was submitted, A revised report shall be required with the Utility Construction Permit submitted as the report recommends that the roof and footing drains be tied into the neighboring storm vault being built by the Veldyke/Webber Short Plat. It is not clear if this in option or if both parties have agreed to this. The Surface Water System Development Charges are based on a rate of $759.00 x 4 single-family homes. The estimated fees based on the proposed plat are $3,036.00. Payment of these fees will be required prior to issuance of utility construction permit. Water and Sanitary Sewer Utilities: The subject site is located within the City of Renton water service area. An 8-inch water main will be extended to the east property line within a 26-foot utility and access easement provided by the Veldyke/Webber Short Plat. An 8-inch sewer main is being extended from NE 19th internally into the short plat. Available fire flow from the dead end main will be 1,250 gpm. The proposed project is located in the 300 Water Pressure Zone and is outside an Aquifer Protection Zone. Static pressure in the area is approximately 80 psi. Fire flow requirement for single-family residences under 3,600 square feet, including garage is 1,000 gpm. Hydrants are required within 300 feet of all structures. Existing hydrants to be counted as fire protection will be required to be retrofitted with a 5-inch storz quick disconnect fitting. Additional fire flow and hydrants are required if the total square footage of the new single-family structures are greater than 3600 square feet. Lots 2, 3, and 4 will require residential fire sprinkler systems. A minimum of a one inch domestic water meter will be required.

STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. Lands in the RSF designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies: Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. The proposal project for four lots would arrive at a net density of 4.25 dwelling units per net acre on the project site, which is within the density range required. The proposal to re-subdivide the Dalpay Estates Division 2 parent parcel into a total of 8 lots would arrive at a net density of 4.5 dwelling units per net acre, which is within the density range required. Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of less than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on lot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation, but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Hexrpt 07-119.doc ' City of Renton P/BIPW Department DALPA Y PRELIMINARY PLAT PHASE Ill Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page 5of9 All of the proposed lots equal or exceed the minimum lot size of 5,000 square feet. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. The proposed new lots would meet the required lot size, width, and setbacks area. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of fife for existing residents. The proposed lots are oriented such that all of the lots would have access to a public right-of-way. Approval of this application would not decrease the quality of life for residents in the immediate vicinity. Policy CD-12. Infill development, defined as new short plats of nine or fewer lots, should be encouraged in order to add variety, updated housing stock, and new vitality to neighborhoods. The proposed short plat would subdivide one existing parcel into four lots. Four new residences would be constructed on the new lots, updating the housing stock in the existing neighborhood. B. Compliance with the Underlying Zoning Designation. The 1.66-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of 4 new single-family residential units. Density-The R-8 zone requires a minimum density of 4.0 dwelling units per net acre (du/ac) and permits a maximum density of 8.0 dwelling units per net acre. Net density is calculated after public rights-of-way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 520 square feet of private streets, and 30,866 square feet of critical areas, the proposal for 4 lots would result in a net density of 4.25 dwelling units per acre (4 lots / 0.94 acres = 4.25 du/ac). In addition, staff reviewed the proposed subdivision in the context of the previously approved Dalpay Estates Division 2 Short Plat. The proposal to subdivide the parent Dalpay Estates Division 2 parcel into 8 lots would result in a density of 4.5 dwelling units per acre. The proposed subdivision would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone is 5,000 sq ft for parcels that total less than 1 acre in net area. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. The proposed plat would create four lots, Lot 1 would have a lot area of 8,140 square feet, Lot 2 would have a lot area of 12,985 square feet, Lot 3 would have a lot area of 10,929 square feet, and Lot 4 would have a lot area of 7,462 square feet. All of the lots would be interior lots as none of the lots abut a public street. The proposed lots would have lot widths ranging from 67 feet to 90 feet. The proposed lots would have lot depths ranging from 84 feet to 223 feet. As proposed the new lots would comply with the City's minimum lot size, width and depth requirements. Setbacks -In the R-8 zone, the minimum front and side yard along street setbacks are 15 feet for the primary residence and 20 feet for an attached garage, the minimum interior side yard setback is 5 feet and the minimum rear yard setback is 20 feet. The proposed lots appear to contain adequate area to provide for the construction of single family residences after the consideration of the setback requirements. Compliance with these setback standards will be verified prior to the issuance of individual building permits. Building Standards -The R-8 zone permits one single family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 sq ft each, or one per lot at 1,000 sq ft in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is 35% or 2,500 square feet, whichever is greater. Hexrpt 07-119.doc City of Renton P/8/PW Department DALPA Y PRELIMINARY PLAT PHASE Iii PUBLIC HEARING DATE: December 4, 2007 Preliminary Reporl to the Hearing Examiner LUA-07-119, PP, ECF Page 6of9 The proposal's compliance with these building standards would be verified prior to the issuance of individual building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping -The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum amount of landscaping required for sites abutting a non-arterial public street is 5 feet provided that if there is additional undeveloped right-of-way in excess of 5 feet, this shall also be landscaped. A determination has been made that if no additional area is available within the public right- of-way due to required improvements, the 5-foot landscaped strip may be located within private property abutting the public right-of-way. The project site does not abut any public street frontages; therefore the 5- foot landscape strip is not required. Two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer) are required to be planted within the 15-foot front yard setback area for the proposed lots. A conceptual landscape plan was submitted with the project application. The landscape plan proposes to plant two Autumn Brilliance Serviceberry trees within the front yard areas of Lot 3 and 4. A total of 4 evergreen trees are proposed to be retained and one 6-7-foot tall Shore Pine is proposed to be planted within the 15-foot front yard area of proposed Lot 2. The submitted plan did not include any trees within the front yard area of proposed Lot 1. The landscape plan shall be revised to include two trees within the front yard area of proposed Lot 1. Staff recommends as a condition of approval that a revised landscape plan be submitted prior to the approval of the final plat showing two trees within the 15-foot front yard area of proposed Lot 1. The revised landscape plan shall be submitted to the Development Services Division project manager for review and approval. The applicant will be required to submit a detailed landscaping plan to the Development Services Division for review and approval prior to the issuance of a building permit. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. As proposed, the lots appear to comply with arrangement and access requirements of the Subdivision Regulations. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. Proposed Lot 1 would be oriented to provide its front yard facing to the north, Lot 2 would be oriented to provide its front yard facing to the south, and Lots 3 and 4 would be oriented to provide their front yards facing to the north. Staff recommends as a condition of approval that a note be placed on the face of the final plat map identifying the orientation of the front yards of each of the new lots. Each of the lots would satisfy the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: There are no property corners at intersections. Access and Street Improvements: Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 is proposed via a 20-foot wide private access street off of Redmond Court NE. Private streets are permitted to serve a maximum of 6 lots provided a minimum of two lots abut a public right-of-way. A joint use driveway is permitted to provide access to a maximum of two lots and is required to have a minimum easement width of 20 feet. The existing 20-foot wide access easement off of NE 191h Street currently is approved to provide access to Lots 1-5 of the Dalpay Estates Division 2 Short Plat that was previously approved. The current project is a re-subdivision of Lot 5 of the Dalpay Estates Division 2 Short Plat. The proposal to provide access to Lot 1 of the proposed subdivision would result in a total of 5 lots accessing off of the easement, which would not exceed the maximum number of 5 lots that were permitted to access off the easement permitted under the Dalpay Estates Division 2 Short Plat.

Therefore, the proposal to provide access to three additional lots (Lots 2-4) proposed to be created under the current subdivision would exceed the maximum number of lots approved to take access off of the existing 20-foot wide easement. In order to provide access to three additional lots, the easement would need to be widened to 26 feet with 20 feet of paving or a Modification to the City's Street Standards would need to be granted. Staff recommends as a condition of approval that a revised plat map be submitted prior to final plat approval widening the existing access easement proposed to provide access to Lots 2-4 to 26 feet with 20 feet of paving or that a Modification to the City's Street Standards be requested and granted by the Development Engineering Supervisor. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Traffic Mitigation Fee. The Traffic Mitigation Fee is based on $75 per net new average daily trip attributed to the proposed subdivision. The proposed 4 new residential lots would be expected to generate approximately 38.28 new average weekday trips (4 new homes x 9.57 trips per home= 38.28). The fee for the proposed plat is estimated to be $2,871 (38.28 total trips x $75.00 = $2,871) and is payable prior to the recording of the plat. Topography and Vegetation: The topography across proposed Lot 1 is relatively flat with a gradual slope towards the protected slope areas located within the proposed NGPE. The topography across Lots 2-4 slopes to the southwest at an average grade of 11 percent. In addition, the topography across the central portion of the site slopes down to a ravine with grades in excess of 40 percent. With the project application, the applicant submitted a Geotechnical Report prepared by Dennis Joule, dated January 16, 2004. The Environmental Review Committee adopted the recommendations found in the submitted geotechnical report as mitigation. A Stream Study prepared by Alder NW, dated November 19, 2007 was submitted for the proposed project. A stream was identified within the ravine located on the central portion of the project site. The stream was classified as an intermittent Class 4 stream. A Class 4 stream requires a 35-foot stream buffer; however the City's Critical Areas Regulations require that when a stream buffer falls within a protected slope, the buffer shall extend to the top of the slope. According to the submitted stream study, portions of the 35-foot required stream buffer falls within the protected slope; therefore where the stream buffer falls within the protected slope area, the buffer extends to the top of the protected slope. No development is proposed within the protected slope or the stream buffer area. To protect the critical areas located on the project site, staff recommends as a condition of approval that a Native Growth Protection Easement shall be recorded over the protected slopes, Class 4 stream, and associated buffer area (Tract A) prior to or concurrent with the recording of the final plat map. To notify future residents of the Dalpay Preliminary Plat Phase Ill of the presence of the critical areas, staff recommends as a condition of approval that the edge of the protected slopes, Class 4 stream, and associated buffer be delineated with a split rail fence and identified with signage as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of Utility Construction Permit Application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The project site is currently forested with a variety of trees, shrubs, and ground cover. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made to preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. A significant tree retention plan was submitted with the project application. According to a tree retention plan that was submitted by the applicant, a total of 96 significant trees are located on-site outside of the NGPE, of those 24 would be required to be retained or replaced. The tree retention plan identifies 44 significant trees that are proposed to be retained, which would comply with the retention requirements. To ensure that none of the trees proposed to be retained are damaged during construction, staff recommends as a condition of approval that the trees proposed to be retained are shown on each of the plans submitted as a part of the Utility Construction Permit Application and that protection measures for the trees to ensure survival during construction of the project be submitted for review and approval by the Development Services Division project manager. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DATE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page Bof9 Temporary Erosion and Sediment Control Plan (TESCP) and the use of Best Management Practices would serve to mitigate potential erosion and off-site sedimentation impacts. The project application includes a Construction Mitigation Plan, which is subject to final approval prior to the issuance of construction permits for the project. Due to the potential for erosion to occur from the project site during construction, the Environmental Review Committee adopted a mitigation measure requiring that erosion control be installed in accordance with the 2005 Department of Ecology Stormwater Management Manual. Relationship to Existing Uses: Single family residential homes surround the subject site. The proposed detached single family residences would be compatible with the surrounding development. D. Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. These fees paid would help offset any additional impacts to emergency services generated from this development. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Fire Mitigation Fee. The Fire Mitigation Fee is based on a rate of $488.00 per new single family lot. The fee is estimated at $1,952.00 ($488 x 4 = $1,952.00) and is payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling. Based on the student generation factor, the proposed plat would potentially result in 2 additional students (0.44 X 4 = 1.76). Storm Drainage/Surface Water: A Technical Information Report prepared by Cramer Northwest, Inc., dated August 13 2007 was submitted with the application materials. According to the report the existing drainage currently sheet flows to the ravine located on the central portion of the project site, where it becomes a small stream, which flows towards NE Sunset Blvd. The submitted report concludes that the proposed project is exempt from detention and water quality improvements per the 1990 King County Surface Water Design Manual. Due to potential downstream drainage problems, the City's Environmental Review Committee imposed a SEPA mitigation measure that requires the project to comply with the 2005 King County Surface Water Design Manual. Applicant will be required to tightline all roof downspout systems and footing drains to a storm system. A geotechnical report dated January 16, 2004 was submitted. A revised report shall be required with the Utility Construction Permit submitted as the report recommends that the roof and footing drains be tied into the neighboring storm vault being built by the Veldyke/Webber Short Plat. It is not clear if this in option or if both parties have agreed to this. The Surface Water System Development Charges are based on a rate of $759.00 x 4 single-family homes. The estimated fees based on the proposed plat are $3,036.00. Payment of these fees will be required prior to issuance of utility construction permit. Water and Sanitary Sewer Utilities: The subject site is located within the City of Renton water service area. An 8-inch water main will be extended to the east property line within a 26-foot utility and access easement provided by the Veldyke/Webber Short Plat. An 8-inch sewer main is being extended from NE 19th internally into the short plat. Available fire flow from the dead end main will be 1,250 gpm. The proposed project is located in the 300 Water Pressure Zone and is outside an Aquifer Protection Zone. Static pressure in the area is approximately 80 psi. Fire flow requirement for single-family residences under 3,600 square feet, including garage is 1,000 gpm. Hydrants are required within 300 feet of all structures. Existing hydrants to be counted as fire protection will be required to be retrofitted with a 5-inch storz quick disconnect fitting. Additional fire flow and hydrants are required if the total square footage of the new single-family structures are greater than 3600 square feet. Lots 2, 3, and 4 will require residential fire sprinkler systems. A minimum of a one inch domestic water meter will be required.

The project site is located south of NE 19th Street and west of Redmond Court NE and is zoned Residential -8 (R-8) dwelling units per acre. The proposed lot sizes are as follows: Lot 1 is 8,140 square feet, Lot 2 is 12,985 square feet, Lot 3 is 12,879 square feet, and Lot 4 is 7,462 square feet. Protected slopes and an unnamed stream are located on the central portion of the project site and would be protected within an NGPE. No development is proposed on the protected slopes or within 30 feet of the stream. The grading would be limited to the construction of the proposed private street and utilities. Approximately 200- 300 cubic yards of grading is proposed. Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 would be provided via a private street off of Redmond Court NE. 2.

The applicant shall pay a Traffic Mitigation Fee in the amount of $75 for each new net daily trip prior to the recording of the final plat. It is anticipated that the proposed project would result in the payment of $2,871.00. 6. The applicant shall pay a Fire Mitigation Fee based on $488.00 per new single family lot prior to the recording of the final plat. The fee is estimated at $1,952. 4. STAFF REVIEW COMMENTS Representatives from various City departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: A. Compliance with the Comprehensive Plan Designation. The site is designated Residential Single Family (RSF) on the Comprehensive Plan Land Use Map. Lands in the RSF designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. The proposal is consistent with the following Comprehensive Plan Land Use and Community Design Element policies: Policy LU-147. Net development densities should fall within a range of 4.0 to 8.0 dwelling units per acre in Residential Single Family neighborhoods. The proposal project for four lots would arrive at a net density of 4.25 dwelling units per net acre on the project site, which is within the density range required. The proposal to re-subdivide the Dalpay Estates Division 2 parent parcel into a total of 8 lots would arrive at a net density of 4.5 dwelling units per net acre, which is within the density range required. Policy LU-148. A minimum lot size of 5,000 square feet should be allowed on in-fill parcels of less than one acre (43,560 sq. ft.) in single-family designations. Allow a reduction on lot size to 4,500 square feet on parcels greater than one acre to create an incentive for aggregation of land. The minimum lot size is not intended to set the standard for density in the designation, but to provide flexibility in subdivision/plat design and facilitate development within the allowed density range. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPA Y PRELIMINARY PLAT PHASE Ill Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF PUBLIC HEARING DA TE: December 4, 2007 Page So/9 All of the proposed lots equal or exceed the minimum lot size of 5,000 square feet. Policy LU-152. Single-family lot size, lot width, setbacks, and impervious surface should be sufficient to allow private open space, landscaping to provide buffers/privacy without extensive fencing, and sufficient area for maintenance activities. The proposed new lots would meet the required lot size, width, and setbacks area. Policy LU-154. Interpret development standards to support new plats and infill project designs incorporating street locations, lot configurations, and building envelopes that address privacy and quality of life for existing residents. The proposed lots are oriented such that all of the lots would have access to a public right-of-way. Approval of this application would not decrease the quality of life for residents in the immediate vicinity. Policy CD-12. Infill development, defined as new short plats of nine or fewer lots, should be encouraged in order to add variety, updated housing stock, and new vitality to neighborhoods. The proposed short plat would subdivide one existing parcel into four lots. Four new residences would be constructed on the new lots, updating the housing stock in the existing neighborhood. B. Compliance with the Underlying Zoning Designation. The 1.66-acre site is designated Residential -8 Dwelling Units per Acre (R-8) on the City of Renton Zoning Map. The proposed development would allow for the future construction of 4 new single-family residential units. Density-The R-8 zone requires a minimum density of 4.0 dwelling units per net acre (du/ac) and permits a maximum density of 8.0 dwelling units per net acre. Net density is calculated after public rights-of-way, private access easements, and critical areas are deducted from the gross acreage of the site. After the deduction of 520 square feet of private streets, and 30,866 square feet of critical areas, the proposal for 4 lots would result in a net density of 4.25 dwelling units per acre (4 lots / 0.94 acres = 4.25 dulac). In addition, staff reviewed the proposed subdivision in the context of the previously approved Dalpay Estates Division 2 Short Plat. The proposal to subdivide the parent Dalpay Estates Division 2 parcel into 8 lots would result in a density of 4.5 dwelling units per acre. The proposed subdivision would comply with density requirements for the R-8 zoning designation. Lot Dimensions and Size -The minimum lot size required in the R-8 zone is 5,000 sq ft for parcels that total less than 1 acre in net area. The minimum lot width required is 50 ft for interior lots and 60 feet for corner lots, and a minimum lot depth of 65 feet is required. The proposed plat would create four lots, Lot 1 would have a lot area of 8,140 square feet, Lot 2 would have a lot area of 12,985 square feet, Lot 3 would have a lot area of 10,929 square feet, and Lot 4 would have a lot area of 7,462 square feet. All of the lots would be interior lots as none of the lots abut a public street. The proposed lots would have lot widths ranging from 67 feet to 90 feet. The proposed lots would have lot depths ranging from 84 feet to 223 feet. As proposed the new lots would comply with the City's minimum lot size, width and depth requirements. Setbacks -In the R-8 zone, the minimum front and side yard along street setbacks are 15 feet for the primary residence and 20 feet for an attached garage, the minimum interior side yard setback is 5 feet and the minimum rear yard setback is 20 feet. The proposed lots appear to contain adequate area to provide for the construction of single family residences after the consideration of the setback requirements. Compliance with these setback standards will be verified prior to the issuance of individual building permits. Building Standards -The R-8 zone permits one single family residential structure per lot. Each of the proposed lots would support the construction of one detached unit. Accessory structures are permitted at a maximum number of two per lot at 720 sq ft each, or one per lot at 1,000 sq ft in size. Accessory structures are permitted only when associated with a primary structure located on the same parcel. Building height in the R-8 zone is limited to two stories and 30 feet for primary structures and 15 feet for detached accessory structures. Maximum building coverage is 35% or 2,500 square feet, whichever is greater. Hexrpt 07M119.doc City of Renton P/8/PW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DA TE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 6 of 9 The proposal's compliance with these building standards would be verified prior to the issuance of individual building permits. Parking -Each detached dwelling unit is required to provide two off-street parking stalls per unit. The proposed building pads appear to be adequately sized for the provision of the required parking. Landscaping -The City's landscaping regulations require the installation of landscaping within the public right-of-way. The minimum amount of landscaping required for sites abutting a non-arterial public street is 5 feet provided that if there is additional undeveloped right-of-way in excess of 5 feet, this shall also be landscaped. A determination has been made that if no additional area is available within the public right- of-way due to required improvements, the 5-foot landscaped strip may be located within private property abutting the public right-of-way. The project site does not abut any public street frontages; therefore the 5- foot landscape strip is not required. Two ornamental trees, a minimum caliper of 1-1/2 inches (deciduous) or 6 -8 feet in height (conifer) are required to be planted within the 15-foot front yard setback area for the proposed lots. A conceptual landscape plan was submitted with the project application. The landscape plan proposes to plant two Autumn Brilliance Serviceberry trees within the front yard areas of Lot 3 and 4. A total of 4 evergreen trees are proposed to be retained and one 6-7-foot tall Shore Pine is proposed to be planted within the 15-foot front yard area of proposed Lot 2. The submitted plan did not include any trees within the front yard area of proposed Lot 1. The landscape plan shall be revised to include two trees within the front yard area of proposed Lot 1. Staff recommends as a condition of approval that a revised landscape plan be submitted prior to the approval of the final plat showing two trees within the 15-foot front yard area of proposed Lot 1. The revised landscape plan shall be submitted to the Development Services Division project manager for review and approval. The applicant will be required to submit a detailed landscaping plan to the Development Services Division for review and approval prior to the issuance of a building permit. C. Compliance with Subdivision Regulations Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. As proposed, the lots appear to comply with arrangement and access requirements of the Subdivision Regulations. Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. Proposed Lot 1 would be oriented to provide its front yard facing to the north, Lot 2 would be oriented to provide its front yard facing to the south, and Lots 3 and 4 would be oriented to provide their front yards facing to the north. Staff recommends as a condition of approval that a note be placed on the face of the final plat map identifying the orientation of the front yards of each of the new lots. Each of the lots would satisfy the minimum lot area and dimension requirements of the R-8 zone. When considering the required setbacks, as well as access points for each lot, the proposed lots appear to have sufficient building area for the development of detached single family homes. Property Corners at Intersections: There are no property corners at intersections. Access and Street Improvements: Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 is proposed via a 20-foot wide private access street off of Redmond Court NE. Private streets are permitted to serve a maximum of 6 lots provided a minimum of two lots abut a public right-of-way. A joint use driveway is permitted to provide access to a maximum of two lots and is required to have a minimum easement width of 20 feet. The existing 20-foot wide access easement off of NE 19'" Street currently is approved to provide access to Lots 1-5 of the Dalpay Estates Division 2 Short Plat that was previously approved. The current project is a re-subdivision of Lot 5 of the Dalpay Estates Division 2 Short Plat. The proposal to provide access to Lot 1 of the proposed subdivision would result in a total of 5 lots accessing off of the easement, which would not exceed the maximum number of 5 lots that were permitted to access off the easement permitted under the Dal pay Estates Division 2 Short Plat. Hexrpt 07-119.doc City of Renton PIBIPW Department DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DATE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 7 of 9 The existing 20-foot wide access easement off of Redmond Court NE was approved as a part of the Veldyke/Webber Short Plat (LUA05-065) to provide access to a maximum of two lots (one of which being Lot 5 of the Veldyke/Webber Short Plat). Therefore, the proposal to provide access to three additional lots (Lots 2-4) proposed to be created under the current subdivision would exceed the maximum number of lots approved to take access off of the existing 20-foot wide easement. In order to provide access to three additional lots, the easement would need to be widened to 26 feet with 20 feet of paving or a Modification to the City's Street Standards would need to be granted. Staff recommends as a condition of approval that a revised plat map be submitted prior to final plat approval widening the existing access easement proposed to provide access to Lots 2-4 to 26 feet with 20 feet of paving or that a Modification to the City's Street Standards be requested and granted by the Development Engineering Supervisor. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Traffic Mitigation Fee. The Traffic Mitigation Fee is based on $75 per net new average daily trip attributed to the proposed subdivision. The proposed 4 new residential lots would be expected to generate approximately 38.28 new average weekday trips (4 new homes x 9.57 trips per home= 38.28). The fee for the proposed plat is estimated to be $2,871 (38.28 total trips x $75.00 = $2,871) and is payable prior to the recording of the plat. Topography and Vegetation: The topography across proposed Lot 1 is relatively flat with a gradual slope towards the protected slope areas located within the proposed NGPE. The topography across Lots 2-4 slopes to the southwest at an average grade of 11 percent. In addition, the topography across the central portion of the site slopes down to a ravine with grades in excess of 40 percent. With the project application, the applicant submitted a Geotechnical Report prepared by Dennis Joule, dated January 16, 2004. The Environmental Review Committee adopted the recommendations found in the submitted geotechnical report as mitigation, A Stream Study prepared by Alder NW, dated November 19, 2007 was submitted for the proposed project. A stream was identified within the ravine located on the central portion of the project site. The stream was classified as an intermittent Class 4 stream. A Class 4 stream requires a 35-foot stream buffer; however the City's Critical Areas Regulations require that when a stream buffer falls within a protected slope, the buffer shall extend to the top of the slope. According to the submitted stream study, portions of the 35-foot required stream buffer falls within the protected slope; therefore where the stream buffer falls within the protected slope area, the buffer extends to the top of the protected slope. No development is proposed within the protected slope or the stream buffer area. To protect the critical areas located on the project site, staff recommends as a condition of approval that a Native Growth Protection Easement shall be recorded over the protected slopes, Class 4 stream, and associated buffer area (Tract A) prior to or concurrent with the recording of the final plat map. To notify future residents of the Dalpay Preliminary Plat Phase Ill of the presence of the critical areas, staff recommends as a condition of approval that the edge of the protected slopes, Class 4 stream, and associated buffer be delineated with a split rail fence and identified with signage as approved by the Development Services Division Project Manager. A fencing and signage detail shall be submitted to the Development Services Division project manager at the time of Utility Construction Permit Application for review and approval. The fencing and signage shall be installed prior to the recording of the final plat. The project site is currently forested with a variety of trees, shrubs, and ground cover. RMC 4-4-070 indicates that existing trees and other vegetation shall be used to augment new plantings for landscaping where practical, and RMC 4-7-130 requires that a reasonable effort should be made to preserve existing trees. A Determination was made by the Director of Development Services that the retention or replacement of 25% of the existing trees would achieve these requirements. A significant tree retention plan was submitted with the project application. According to a tree retention plan that was submitted by the applicant, a total of 96 significant trees are located on-site outside of the NGPE, of those 24 would be required to be retained or replaced. The tree retention plan identifies 44 significant trees that are proposed to be retained, which would comply with the retention requirements. To ensure that none of the trees proposed to be retained are damaged during construction, staff recommends as a condition of approval that the trees proposed to be retained are shown on each of the plans submitted as a part of the Utility Construction Permit Application and that protection measures for the trees to ensure survival during construction of the project be submitted for review and approval by the Development Services Division project manager. Hexrpt 07-119.doc City of Renton P/8/PW Deparlment DALPAY PRELIMINARY PLAT PHASE Ill PUBLIC HEARING DATE: December 4, 2007 Preliminary Report to the Hearing Examiner LUA-07-119, PP, ECF Page 8019 Temporary Erosion and Sediment Control Plan (TESCP) and the use of Best Management Practices would serve to mitigate potential erosion and off-site sedimentation impacts. The project application includes a Construction Mitigation Plan, which is subject to final approval prior to the issuance of construction permits for the project. Due to the potential for erosion to occur from the project site during construction, the Environmental Review Committee adopted a mitigation measure requiring that erosion control be installed in accordance with the 2005 Department of Ecology Stormwater Management Manual. Relationship to Existing Uses: Single family residential homes surround the subject site. The proposed detached single family residences would be compatible with the surrounding development. D. Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the applicant's provision of Code required improvements and fees. These fees paid would help offset any additional impacts to emergency services generated from this development. To mitigate impacts to the local street system, the Environmental Review Committee imposed mitigation on the project in the form of the requirement for payment of a Fire Mitigation Fee. The Fire Mitigation Fee is based on a rate of $488.00 per new single family lot. The fee is estimated at $1,952.00 ($488 x 4 = $1,952.00) and is payable prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District No. 403. According to the Draft Environmental Impact Statement for the City of Renton Land Use Element (January 16, 1992), the City of Renton has a student generation factor of 0.44 students per single-family residential dwelling. Based on the student generation factor, the proposed plat would potentially result in 2 additional students (0.44 X 4 = 1.76). Storm Drainage/Surface Water: A Technical Information Report prepared by Cramer Northwest, Inc., dated August 13 2007 was submitted with the application materials. According to the report the existing drainage currently sheet flows to the ravine located on the central portion of the project site. where it becomes a small stream, which flows towards NE Sunset Blvd. The submitted report concludes that the proposed project is exempt from detention and water quality improvements per the 1990 King County Surface Water Design Manual. Due to potential downstream drainage problems, the City's Environmental Review Committee imposed a SEPA mitigation measure that requires the project to comply with the 2005 King County Surface Water Design Manual. Applicant will be required to tightline all roof downspout systems and footing drains to a storm system. A geotechnical report dated January 16, 2004 was submitted. A revised report shall be required with the Utility Construction Permit submitted as the report recommends that the roof and footing drains be tied into the neighboring storm vault being built by the Veldyke/Webber Short Plat. It is not clear if this in option or if both parties have agreed to this. The Surface Water System Development Charges are based on a rate of $759.00 x 4 single-family homes. The estimated fees based on the proposed plat are $3,036.00. Payment of these fees will be required prior to issuance of utility construction permit. Water and Sanitary Sewer Utilities: The subject site is located within the City of Renton water service area. An 8-inch water main will be extended to the east property line within a 26-foot utility and access easement provided by the Ve/dyke/Webber Short Plat. An 8-inch sewer main is being extended from NE 19'" internally into the short plat. Available fire flow from the dead end main will be 1,250 gpm. The proposed project is located in the 300 Water Pressure Zone and is outside an Aquifer Protection Zone. Static pressure in the area is approximately 80 psi. Fire flow requirement for single-family residences under 3,600 square feet, including garage is 1,000 gpm. Hydrants are required within 300 feet of all structures. Existing hydrants to be counted as fire protection will be required to be retrofitted with a 5-inch storz quick disconnect fitting. Additional fire flow and hydrants are required if the total square footage of the new single-family structures are greater than 3600 square feet. Lots 2, 3, and 4 will require residential fire sprinkler systems. A minimum of a one inch domestic water meter will be required.

All short plats shall provide separate water services to each building lot prior to recording of the short plat. Separate permits and fees for water meters will be required. Water System Development Charges are based on a rate of $1,956.00 x 4 new single-family homes. The estimated fees based on the proposed plat layout are $7,824.00. Payment of these fees will be required prior to issuance of utility construction permit. The subject property is served by City of Renton sewer service. An 8-inch sewer main will be extended to the east property line within a utility and access easement provided by the Veldyke/Webber Short Plat. The Veldyke/Webber Short Plat is extending an 8-inch sewer main from NE 19th internally into the short plat. A separate side sewer stub to each new lot is required prior to the recording of the plat, the minimum slope shall be 2 percent. Sanitary Sewer System Development Charges are based on a rate of $1,017.00 x 4 new single-family homes. The estimated fees based on the proposed plat layout are $4,068.00. Credit is given to the existing homes connected to sewer. Payment of these fees will be required prior to issuance of utility construction permit. This site is subject to the Honey Creek Special Assessment District. Charges are based on a rate of $250.00 x 4. Fees based on the site plan are $1,000.00. Payment of these fees will be required prior to issuance of issuance of the utility construction permit. H.

PROJECT NAME: Dalpay Preliminary Plat Phase 111 PROJECT NUMBER: LUA07-119, PP, ECF PROJECT DESCRIPTION: The applicant is requesting Preliminary Plat approval and Environmental (SEPA) Review for the subdivision of an existing 72,332 square foot lot zoned Residential -8 dwelling units per acre (R-8) into 4 lots. The project site was previously part of the Dalpay Estates Div II short plat (LUA03-125), which was recorded in September of 2005 (recording# 20050927900007). As the site was previously part of a subdivision that was recorded less than 5 years ago, the current subdivision is required to be reviewed as a preliminary plat. The proposed lot sizes are as follows: Lot 1 is 8,140 square feet, Lot 2 is 12,985 square feet, Lot 3 is 12,879 square feet, and Lot 4 is 7,462 square feet. Access to Lot 1 would be provided via an existing 20-foot wide private access easement off of NE 19th Street and access to lots 2-4 would be provided via a private street off of Redmond Court NE. Steep slopes and an unnamed stream are located on the project site and would be protected in a sensitive area tract. HEX Agenda 12-4-07.doc
