I. GENERAL INFORMATION Applicant: Surveyor: Bobby Swanson S. 312 Farr Road Spokane, WA 99206 (509) 926-0755 Sara Marks W. 1801 Broadway Ave. #110 Spokane, WA 99201 (509) 328-5139 Contact Planner: Tim Lawhead (509) 456 -2205 Location: Generally located north of and adjacent to Broadway Avenue, approximately 1/4 mile east of Flora Road in Section 18, Township 25 North, Range 45 EWM, Spokane County, Washington. Proposal: Preliminary plat to divide approximately 2.63 acres into 8 lots for single family residences and those uses allowed in the Urban Residential -3.5 (UR- 3.5) zone. II. SITE INFORMATION A . Site Size: 2.63 acres Gross Density: 3.04 units per acre B . Comprehensive Plan 1. Land Use Plan: The property is located within the Urban category of the Comprehensive Plan. The Urban category is primarily a residential category of single family, two family, multiple family and condominiums along with neighborhood commercial, industrial parks and recreational 7/93 HEC Staff Report for PE- 1712 -93 Page 100 facilities. This category is intended to provide the opportunity for development of a "city like" environment. Urban areas will be the most intensely developed of all categories. Urban areas will have public water systems, sanitary sewer systems and other public facilities. The net density (excluding roads) should range between 1 and 17 dwelling units per acre within the Urban category. The net density for the proposal is 3.79 dwelling units per acre. The project is inside the Priority Sewer Service Area (PSSA). The proposal is consistent with and implements the Urban category of the Comprehensive Plan. 2 . Arterial Road Plan: The site is adjacent to Broadway Avenue which is designated as a Minor Arterial by the Spokane County Arterial Road Plan. The existing right of way width is 60 feet. In order to implement the Arterial Road Plan, the County Engineer has required that the applicant dedicate a strip of land, 2 feet wide, along the site's Broadway Avenue frontage. In addition, a strip of land 8 feet wide shall be set aside as a future acquisition area. C . Site Characteristics: The topography of the site is essentially flat. A small dilapidated storage shed is located on the site which will be removed prior to any development. The site is vegetated with grass and used for pasture. D. Neighborhood Characteristics: Within 1/4 mile of the site, parcel sizes range from 10,000 square feet to 5 acres and the average parcel size is approximately 3/4 acre. Single family residences are the dominant land use and large animal keeping is common. I -90 borders the site on the north. E. Zoning Analysis: Since January 1, 1991 the site has been zoned Urban Residential -3.5 (UR -3.5). The current UR -3.5 zoning resulted from implementation of the new Zoning Code. From 1961 until the Zoning Code was fully implemented on January 1, 1991, the site and surrounding area was zoned Agriculture (A). Proposal: Urban Residential -3.5 established on January 1, 1991. North: Urban Residential -3.5 (UR -3.5) established on January 1, 1991. South: Urban Residential -3.5 (UR -3.5) established on January 1991. Fast: Urban Residential -3.5 (UR -3.5) established on January 1, 1991. West: Urban Residential -3.5 (UR -3.5) established on January 1, 1991. F . Land Use Analysis: Most property surrounding the proposal is developed with single family residences on lots ranging from 10,000 square feet to 5 acres. Refer to Section D., Neighborhood Characteristics, for additional information on surrounding land use. 7/93 HEC Staff Report for PE- 1712 -93 Page 101 Site: , Vacant, undeveloped, pasture. North: Interstate -90. South: Single family residences and pasture. Fast• Single family residences and pasture. West: Single family residences. G . Circulation: The site fronts on Broadway Avenue which is designated as a Minor Arterial. The County Engineer has required that Broadway Avenue be widened with 12 to 14 feet of asphalt along the frontage of the development. The construction of curb and sidewalk is also required. All lots within the project will be accessed from a public road and cul -de -sac. The road will be paved to a width of 36 feet and will be curbed. H . Design: The preliminary plat design illustrates for standard rectangular and cul- de -sac lots ranging from 10,361 to 13,163 square feet. Street frontage is 80 feet or greater. The minimum lot size in the Urban Residential -3.5 zone is 10,000 square feet. The minimum street frontage is 80 feet. Prior to plat finalization all lots will be checked to assure that zoning standards are met. I. Density: The density is consistent with Urban, Comprehensive Plan, U net density (excluding roads) is 3.79 dwelling units per acre. J. Drainage: A drainage plan is required. This plan must be reviewed and approved by the County Engineer's Department prior to development. The proposal is inside the Aquifer Sensitive Area, therefore "208" storm drainage requirements must be met.. K . Water Supply: The proposal is within the Consolidated Irrigation District. The water district has indicated that they will be able to supply the proposal. A Water Plan will be required. L . Sewage Disposal: Individual on -site septic systems are proposed for sewage disposal and are subject to approval by the Spokane County Health District. All dwelling units will be double plumbed and dry line sewers will be installed to facilitate connection to the public sewer when it is available. M. School: The proposal is in the Central Valley School District No. 356. The Central Valley School District has submitted a letter indicating that schools are currently over crowded. The District suggests that the plat should be denied unless approved with a condition that the developer and the District agree to voluntary fees. The Planning Department has included a condition of approval requiring the project sponsor to negotiate a voluntary agreement with the School District to mitigate impacts of the development on schools. 7/93 HEC Staff Report for PE- 1712 -93 Page 102 N . Fire Protection: The proposal is within Fire District No. 1. The Fire District has required 1 fire hydrant at the entrance to the development. All Fire District requirements must be met prior to finalization of the plat. O. 'Cultural Resources: None have been identified. P . Parks and Recreation: The nearest County park to the site is Sullivan Park which is located approximately 2 miles northwest of the site. Sullivan Park is a 10 acre park equipped with picnic facilities, rest rooms, play equipment, ball field and hiking trails. According to the Spokane County Parks and Recreation Plan, the East Valley Suburban Area has a deficit of park land. The "Plan" recommendations include acquisition of 6 new park sites within the East Valley Suburban Area as well as improvements and expansions of existing parks. The Parks Department has requested that the project sponsor negotiate a voluntary agreement to mitigate impacts on park facilities and provide adequate facilities under RCW 82.02.020 and 58.17.110. This request is included as a condition of approval by the Planning Department. S . Transit: The project is inside the Spokane Transit Authority Benefit Area. Transit service is available approximately 2 blocks west of the proposal at the Flora Road/Broadway Avenue intersection. III. ENVIRONMENTAL REVIEW: An Environmental Checklist was submitted by the sponsor and was reviewed by the County Planning Department. The review considered the specifics of the proposal, other available information, County ordinances, other regulations and laws, possible standard Conditions of Approval, the Generalized Comprehensive Plan, and other County policies and guidelines. The Planning Department has determined that "No probable significant adverse impacts" would result from the proposal being developed and has issued a Determination of Nonsienifrcance ("DNS"). The "DNS" was circulated to 12 other agencies of jurisdiction and other agencies/departments affected by the future development for review and comment. The "DNS" comment period ends July 20, 1993 and was advertised 15 calendar days before said date in the newspaper, by letter to adjacent property owners within 400 feet of the proposal, and by notice on a sign posted on the proposal site. The Hearing Examiner may consider additional environmental related testimony at the public hearing. IV. PLANNING DEPARTMENT SUMMARY AND RECOMMENDATION The proposal conforms to the County Subdivision and Zoning Code regulations. The proposal is also consistent with the Urban Category of the Comprehensive Plan density guidelines. Past land use decisions have considered the availability of sewers and the impact of on -site sewage disposal systems on the Aquifer. As conditioned, the proposal makes adequate provisions for schools, roads, parks and open space as required by RCW 58.17.110. The Planning Department recommends approval of the 7/93 HEC Staff Report for PE- 1712 -93 Page 103 preliminary plat subject to the conditions of approval recommended by reviewing agencies. V.

Lot Plans Provide lot plans to scale for those lots which will have drainage easements. See attached check sheet for detailed requirements. Drainage Calculations Page 5 of 5 Provide a drainage Basin Map showing the on -site subbasins, and off -site basins (if any) flowing onto the property. The Basin Map is to include the following information: * Show topographic features of the site: including contours, stream channels, road ditches and other intersecting man -made channels, and sketch on any relevant structures or streets. * If there are any contributing off -site drainage basins flowing onto the property, then show the topographic features for those areas, the requirements are listed above. * Provide a scale and north arrow. Include the street frontage area, from centerline, in the '208' volume calculations, because it will flow into the pond. * Show the hydrologic travel route used for calculating the time of concentrations, Tc. The Tc route muse be shown for each basin /subbasin. If the Tc is comprised of more than one incremental time (which is normally the case), then label each incremental time Ti, T2, T3, etc. These labels are to be in both the Basin Map and calculations so they can be readily correlated. Identify the location of the Point of Concentration, PC, located at the downstream end of each subbasin. Because the basin map provided is quite inadequate, the storm calculations are considered incomplete and are being returned without being reviewed.

With these plans we provided "R" value test results to assist the county in designing the typical paved roadway section on site. It has come to my attention, through another project, that the information submitted was insufficient and with this update we hope to fill in the missing variables needed by the county to complete the design. The map of the site included shows the sample collection point on the proposed construction site. I have also included an addition to the original geotechnical report provided by the geotechnical engineer. If you have any questions regarding the above stated project, please contact me or Jeff Logan at (509) 328 -5139.

Provide a brief report, with horizontal and vertical profile exhibits, and showing sight triangles. If the sight triangles are outside of the right -of -way, then an easement is to be obtained and shown in the engineering plans. Approval of the calculations should be obtained prior to recording the easement. Normally stationing of roadways in the plans should be west to east, south to north and left to right. It is not necessary to change the stationing in these plans, however keep this drafting standard in mind when working on future projects. 6) List the bench mark location, description, and its elevation.

Lot Plans Provide lot plans to scale for those lots which will have drainage easements. See attached check sheet for detailed requirements. Drainage Calculations Provide a drainage Basin Map showing the on -site subbasins, and off -site basins (if any) flowing onto the property. The Basin Map is to include the following information: * Show topographic features of the site: including contours, stream channels, road ditches and other intersecting man -made channels, and sketch on any relevant structures or streets. * If there are any contributing off -site drainage basins flowing onto the property, then show the topographic features for those areas, the requirements are listed above. * Provide a scale and north arrow. * ' Include the street frontage area, from centerline, in the '208' volume calculations, because it will flow into the pond. * Show the hydrologic travel route used for calculating the time of'■ . concentrations, Tc. The Tc route muse be shown for each .---, basin /subbasin. If the Tc is comprised of more than one incremental time (which is normally the case), then label each incremental time Ti, T2, T3, etc. These labels are to be in both the Basin Map and calculations so they can be readily correlated. Identify the location of the Point of Concentration, PC, located at the downstream end of each subbasin.

Township 25 N.. Range 45 E. WM, Spokane County, Washington. The property is located within the Urban category and is within the Aquifer Sensitive Area (ASA) Overlay zone. The soil in the area is classified as GgA (Garrison) based on Sheet 67 of the Soil Survey of Spokane County, Washington. A copy of this sheet is attached. The GgA soil is excessively drained and has moderately rapid permeability. Based on the Spokane County Guidelines for Stormwater Management, this soil type allows the use of Spokane County type "A" or "B" standard concrete drywells. The project is composed of four sub - drainage basins defined by proposed topography and roadway design. Each sub- drainage basin will be sized to handle the treatment of its respective impervious area =off contribution. The resulting outflow will be handled in a dry at the low end of the overall watershed. See appendix for a map which defines these basins PROJECT PURPOSE: In accordance with the Planning Department report dated 7/27/93, (PE- 1712 -93) this project lies within the ASA Overlay zone and is subject to '208' requirements. To assure that these requirements are met. "a drainage plan is required. This drainage plan will determine the storm water facilities required to adequately handle the runoff from a ten year design storm in post development condition. In accordance with the Guidelines for Stormwater Management, the "rational method" will be used to deterrnine the peak discharges and runoff volumes for the various basins. This method is considered adequate for basins less than 10 acres in size. Numerous graphs and charts which appear in this publication will also be used and referenced accordingly. 1 CALCULATIONS: The total basin area and the impervious basin area used in the following calculations is summarized below. Using the # of lots divided by the total basin area, Table 1 in the Guidelines was used to determine the runoff coefficient.

FT Four '208' basins and one drywell were designed using the guidelines identified in addendum #2 - Modified Rational Method Hydrographs. The peak flows for the subdivision will be disposed of in one type "B" drywell. This drywell will be utilized in combination with '208' basins to adequately treat and dispose of the stormwater runoff. The type "B" drywell and '208' basin will be located on the .vest side of the Corbin Court cul -de- sac. See the included drainage basin layout map for the '208' basin layout. Curb inlet capacity design calculations have been provided to show the required length of each inlet. The residual flow from each non - drywell '208' will be handled at the next consecutive drainage basin. 2 SUB -BASIN #2 • DRAINAGE BASIN LAYOUT MAP • SCS PROJECT LOCATION • OVERALL WATERSHED STORM FLOW CALCULATIONS SUB -BASIN #I APPENDIX • '208' POND CALCULATIONS • CURB INLET CALCULATIONS WITH RESIDUAL • '208' POND CALCULATIONS • CURB INLET CALCULATIONS WITH RESIDUAL SUB -BASIN #3 • '208' POND CALCULATIONS • CURB INLET CALCULATIONS WITH RESIDUAL SUB -BASIN #4 • '208' POND CALCULATIONS • CURB INLET CALCULATIONS WITH RESIDUAL • SITE DISTANCE TRIANGLE ANALYSIS • CURB CAPACITY NOMOGRAPH • RUNOFF COEFFICIENTS (C) • RAINFALL INTENSITY CURVES • CHANNEL FLOW NOMOGRAPH • MANNINGS "n" VALUES • BROADWAY AVENUE GRADING SHEET • ASPHALT SECTION DESIGN & "R" VALUE RESULTS 3 1 1 1 1 1 1 \ LOT 3 SUB —BASIN #4 1 PROPOSED - 1 _ LOCATION LOT 4 PROPOSED DRYWELL LOCATION 1 LOT 2 1 } SUB —BASIN /J1 1 1 1 1 1 1 LOT 1 98 Pzi BROADWAY AVENUE SCALE: 1" =50' 1 { DRAINAGE BASIN OVERVIEW 1 BROADWAY SUBDIVISION 1 PROPOSED LOCATION 208' LOT 5 LOT 8 SUB —BASIN $9 PROPOSED '208' LOCATION LOT 7 SUB —BASIN #2 LOT 8 • - _ 97 IMPERVIOUS AREA 98 WAV MIS o 6ItaRS • 5CRVEYCK5 ►.
