The Urban category of the Plan supports a range of residential net densities from 1 to 17 units per acre. The proposed net density of 3.9 units per acre is in accord with the Urban category. The following objectives of the Urban category of the Plan are applidable to this proposal: 1.1_a Promote fill -in within established development areas and existing outlying communities where utilities, arterials, schools and community facilities have already been established. The proposal is located between two existing subdivisions, with school facilities established and has direct access to a Principal arterial. 2 . Arterial Road Plan: The County Arterial Road Plan identifies Wellesley Avenue as a principal arterial with an existing right of way width of 60 feet and a planned width of 100 feet. In order to implement the plan, the County Engineer is requesting 10 feet of dedication and 10 feet be set aside as future acquisition area. The internal roadway serving the site is not designated as an arterial. 3 . County Parks Plan: The Spokane County Parks and Recreation Plan identifies a Community Park within 1 1/2 miles of the site. Plante's Ferry, a 19 acre park is located along Upriver Drive, west of the proposal. The park overlooks the Spokane River and features picnic areas, play equipment and is along the Centennial Trail. C. Site Characteristics: The site is flat with native and pasture grasses. The site contains a house and three accessory structures located at the southwest corner of the lot. The Planning Department, as conditions of approval, will make provisions for the existing structures on the site. The remainder of the parcel is vacant, but was previously utilized for agricultural pursuits. Single- family residences border the site on both the east and west property lines. Wellesley Avenue is adjacent to the site on the south. D. Neighborhood Characteristics: The surrounding neighborhood is predominantly single - family residences. North of the site is open, vacant land. Trentwood Elementary School is located approximately 800 feet east of the proposal, along Wellesley Avenue. Farther east on Wellesley Avenue is East Valley High School. There are older and higher density single - family developments located to the south of the site. E. Zoning Analysis: The surrounding area to the north, south, east, and west is zoned Urban Residential-3.5 (UR -3.5) The sponsor is not requesting a rezone for this proposal and is seeking to create fifteen (15) lots for single- family residences pursuant to the development standards of the existing Urban Residential-3.5 (UR -3.5) zone. North: Urban Residential-3.5 (UR -3.5) established in 1991, previously classified as Agricultural. (ZE -5 -61) 4/93 HEC Staff Report for PE- 1697 -93 Page 87 South: Urban Residential -3.5 (UR -3.5) established in classified as Residential -1 . (7F- 4- 24 -42) East: Urban Residential -3.5 (UR -3.5) established in classified as Residential -I, (ZE- 215 -78) West: Urban Residential -3.5 (UR -3.5) established in classified as Agricultural. (ZE -5 -61) 1991,previously 1991, previously 1991, previously F. Land Use Analysis: The surrounding land use is primarily residential. The subject property and other properties in the area were previously used for agriculture. There has not been recent requests for zone reclassifications or subdivisions in the immediate vicinity. This proposal would be considered a "fill -in" development. There are two schools within a mile of the proposal, Trentwood Elementary and East Valley High School. There may be some large animal keeping in the area as it was a permitted use in the formerly designated Agricultural zone. Site: The existing land use is residential. There is one single- family dwelling on the site, along with accessory structures. The proposed land uses are residential and those uses permitted in the underlying zone. North: The land north of the site is presently undeveloped and vacant. Agricultural activities were pursued in the past and there may be small scale crops that are currently harvested. South: The area south of the proposal is predominantly residential with single - family lots. The lots adjacent to Wellesley Avenue are larger half acre to one acre lots with platted areas further south consisting of smaller lots of 7,000 to 10,000 square feet. East: The land lying east of the proposal is largely residential with lot sizes of approximately 11,000 square feet. Hendrickson Subdivision, a 20 lot subdivision, lies adjacent to the proposal on the east property line and features typical lot sizes of 80X136'. The Trentwood Elementary schoolgrounds lie east of the site on Wellesley, which contain recreation facilities. West: The area to the west is residential with approximately 20,000 square foot lots. A 10 lot subdivision, Alexander's Subdivision is located adjacent to the proposal on the west and contains 10 lots with typical lot sizes of 95'X216'. Further along Wellesley, where Wellesley connects with Upriver Drive is the Spokane River, Centennial Trail, and Plante's Ferry Park. G . Circulation: Access to the proposed subdivision is from Wellesley Avenue. Direct access from lots to Wellesley is not permitted. Enema] access will be from 4/93 HEC Staff Report for PE- 1697 -93 Page 88 1 . Preliminary Plat Data Building Setbacks: Front yard Flanking yard Side yard Rear yard Best Road. Best Road will be constructed with a temporary cul -de -sac with a 50 foot right of way, which includes 36 feet of paving with curb. There is a 25 feet unimproved half (1/2) right of way along the north property line of this site. It may be constructed in the future to provide connection to the existing subdivision east of the subject site which also has a east/west 1/2 right -of -way. The County ' Engineer is requesting 25 feet of dedication for this 1/2 right of way. H . Design: All lots within the proposed subdivision are rectangular in design and have frontage on a public right of way. Many of the lots just meet the minimum lot size of 10, 000 square feet required in the Urban Residential -3.5 (UR -3.5) zone. If any lots do not meet the minimum 10,000 square feet requirement at final plat submittal, the sponsor will be required to apply for an administrative exception for a deviation from the minimum lot standards, or adjust the lot lines to comply with with the zoning standards. The proposal has limitations as to lot depths because of the narrow width of the parcel. The public road creates the need for a 50 foot width right -of -way and therefore creates lot depths of 104 feet and 87 feet. Building setbacks create Limited building area on the smaller lots. Proposed Required 30 feet 25 feet 5 feet @ story 20 feet 30 feet 25 feet 5 feet @ story 20 feet NO1 E: The existing structures on the 2, Block 1 and Lot 4, Block 1 will have non- conforming setbacks. Other Site Plan Considerations: The preliminary plat submitted for review indicates a 25 foot setback from the future acquisition area (FAA). The Comprehensive Plan recommends a setback of 35 feet from Principal Arterials. I. Density: The proposed net density is 3.9 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. K. Power Transmission Lines /Other Known Easements: Final plat process requires disclosure of all recorded easements. L . Water Supply: The proposal is within the Trentwood Irrigation Water District. The sponsor will be required to satisfy water district conditions prior to final plat approval. 4/93 HFC Staff Report for PE- 1697 -93 Page 89 M. Sewage Disposal: Sewage disposal shall be accomplished by individual on- site systems. The sponsor will be required to double -plumb and install dry line sewer for future hook -up to a public sewer system. N . School: The proposal is in the East Valley School District No. 361. No comments were received by the school district. O. Fire Protection: The proposal is within Fire District No. 1 . The Fire District and the Division of Buildings Department (Fire Marshall) are required to approve fire protection provisions prior to finalizing the preliminary plat. P . Wetlands: Spokane County Wetland Inventory Maps do not indicate any wetlands on the site. Q. The site is associated with an area of special flood hazard. The regulations of the National Flood Insurance Program may be applicable to this proposal. The County Engineer has included in its conditions of approval provisions for these regulations with the final plat review process. Cultural Resources: None have been identified. R . Special Information: This parcel presently has preliminary short plat approval (SP.- 730 -91). Upon approval of this preliminary plat, SP- 730 -91 will become null and void. III. ENVIRONMENTAL REVIEW: An Environmental Checklist was submitted by the sponsor and was reviewed by the County Planning Depat tutent. 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 Nonsignificance ( "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 April 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.

EXPIRES 9/24i qy - Todd R. Whipple, P.E. PURPOSE The purpose of this report is to determine the extent of storm drainage facilities which will be required to dispose of stormwater runoff created by the development of Drake Estates. The storm drainage facilities on this project will be designed to dispose of runoff resulting from a ten year design storm. This development is within the Aquifer Sensitive Area (ASA), and is subject to '208' requirements. ANALYSIS METHODOLOGY The Rational Method is recommended for basins less that ten acres in size, and will be used to determine the peak discharges and runoff volumes. PROJECT DESCRIPTION Drake Estates is a 15 lot plat for single family housing located in Spokane County in Section 35, Township 26 N., Range 44 EWM. Sheet 58 of the Soil Survey of Spokane County, Washington shows that the soil types are GgA (Garrison gravelly loam, 0 -5 % slopes), a somewhat excessively drained soil formed from a variety of igneous rock. From page 6 -18 of the Guidelines for Stormwater Manaeement, this soil belongs to Soil Group B. The project has been divided into 6 basins, Q through U, by the crowns and highpoints of the road design. CALCULATIONS The total and the impervious basin areas used to calculate the times of concentration and the peak flows for each basin are shown on the following pages and tabulated below.

Cq . .35 .30 .30 .30 .30 .25 The runoff coefficients ( "C ") shown in Table 1 were based on the number of dwelling units per gross acre according to Spokane County's Guidelines for Stormwater Manaeement. DESIGN The Bowstring calculations on the previous pages show the required retention volumes and '208' storage volumes for each basin. The required volumes for the '208' ponds and drywells from the Bowstring calculations are tabulated below with the provided volumes and drywells types.

Todd R. Whipple, P.E. PURPOSE The purpose of this report is to determine the extent of storm drainage facilities which will be required to dispose of stormwater runoff created by the development of Drake Estates. The storm drainage facilities on this project will be designed to dispose of runoff resulting from a ten year design storm. This development is within the Aquifer Sensitive Area (ASA), and is subject to '208' requirements. ANALYSIS METHODOLOGY The Rational Method is recommended for basins less that ten acres in size, and will be used to determine the peak discharges and runoff volumes. PROJECT DESCRIPTION Drake Estates is a 15 lot plat for single family housing located in Spokane County in Section 35, Township 26 N., Range 44 EWM. Sheet 58 of the Soil Survey of Spokane County, Washington shows that the soil types are GgA (Garrison gravelly loam, 0 -5% slopes), a somewhat excessively drained soil formed from a variety of igneous rock. From page 6 -18 of the Guidelines for Stormwater Manaeement, this soil belongs to Soil Group B. The project has been divided into 6 basins, Q through U, by the crowns and highpoints of the road design. CALCULATIONS The total and the impervious basin areas used to calculate the times of concentration and the peak flows for each basin are shown on the following pages and tabulated below.

DESIGN The Bowstring calculations on the previous pages show the required retention volumes and '208' storage volumes for each basin. The required volumes for the '208' ponds and drywells from the Bowstring calculations are tabulated below with the provided volumes and drywells types.

EXPIRES 9/24/ OFFICIAL PUBLIC DOCUMENT Todd R. Whipple, P.E. SPOKANE COUNTY ENGINEERS OFFICE ORI9 PROJECT $ SUBMITTAL a RETURN TO COUNTY ENGINEER The purpose of this report is to determine the extent of storm drainage facilities which will be required to dispose of stormwater runoff created by the development of Drake Estates. The storm drainage facilities on this project will be designed to dispose of runoff resulting from a ten year design storm. This development is within the Aquifer Sensitive Area (ASA), and is subject to '208' requirements. ANALYSIS METHODOLOGY The Rational Method is recommended for basins less that ten acres in size, and will be used to determine the peak discharges and runoff volumes. • PROJECT DESCRIPTION Drake Estates is a 15 lot plat, for single family housing located in Spokane County in Section 35, Township 26 N., Range 44 EWM. Sheet 58 of the Soil Survey of Spokane County, Washington shows that the soil types are GgA (Garrison gravelly loam, 0 -5 % slopes), a somewhat excessively drained soil formed from a variety of igneous rock. From page 6 -18 - of the Guidelines for Stormwater Management_ this soil belongs to Soil Group B. er,—,%naeo 4,1 FIELD o&SEgv.1no'4 The project has been divided into 6 basins, Q through U, by the crowns and highpoints of the road design. en 6-11-94 CALCULATIONS The total and the impervious basin areas used to calculate the times of concentration and the "- peak flows for each basin are shown on the following pages and tabulated below.

The Urban category of the Plan supports a range of residential net densities from 1 to 17 units per acre. The proposed net density of 3.9 units per acre is in accord with the Urban category. The following objectives of the Urban category of the Plan are applicable to this proposal: 1.1.a Promote fill -in within established development areas and existing outlying communities where utilities, arterials, schools and community facilities have already been established. The proposal is located between two existing subdivisions, with school facilities established and has direct access to a Principal arterial. 2 . Arterial Road Plan: The County Arterial Road Plan identifies Wellesley Avenue as a principal arterial with an existing right of way width of 60 feet and a planned width of 100 feet. In order to implement the plan, the County Engineer is requesting 10 feet of dedication and 10 feet be set aside as future acquisition area. The internal roadway serving the site is not designated as an arterial. 3 . County Parks Plan: The Spokane County Parks and Recreation Plan identifies a Community Park within 1 1/2 miles of the site. Plante's Ferry, a 19 acre park is located along Upriver Drive, west of the proposal. The park overlooks the Spokane River and features picnic areas, play equipment and is along the Centennial Trail. C. Site Characteristics: The site is flat with native and pasture grasses. The site contains a house and three accessory structures located at the southwest corner of the lot. The Planning Department, as conditions of approval, will make provisions for the existing structures on the site. The remainder of the parcel is vacant, but was previously utilized for agricultural pursuits. Single- family residences border the site on both the east and west property lines. Wellesley Avenue is adjacent to the site on the south. D. Neighborhood Characteristics: The surrounding neighborhood is predominantly single - family residences. North of the site is open, vacant land. Trentwood Elementary School is Located approximately 800 feet east of the proposal, along Wellesley Avenue. Farther east on Wellesley Avenue is East Valley High School. There are older and higher density single - family developments located to the south of the site. E. Zoning Analysis: The surrounding area to the north, south, east, and west is zoned Urban Residential -3.5 (UR -3.5) The sponsor is not requesting a rezone for this proposal and is seeking to create fifteen (15) lots for single - family residences pursuant to the development standards of the existing Urban Residential -3.5 (UR -3.5) zone. North: Urban Residential -3.5 (UR -3.5) established in 1991, previously classified as Agricultural. (ZE -5 -61) 4/93 I-IEC Staff Report for PE- 1697 -93 Page 87 South: Urban Residential -3.5 (UR -3.5) established in classified as Residential -1 . (ZE- 4- 24 -42) East: Urban Residential -3.5 (UR -3.5) established in classified as Residential -1, (ZE- 215 -78) West: Urban Residential -3.5 (UR -3.5) established in classified as Agricultural. (ZE -5 -61) F. Land Use Analysis: 1991,previously 1991, previously 1991, previously The surrounding land use is primarily residential. The subject property and other properties in the area were previously used for agriculture. There has not been recent requests for zone reclassifications or subdivisions in the immediate vicinity. This proposal would be considered a "fill -in" development. There are two schools within a mile of the proposal, Trentwood Elementary and East Valley High School. There may be some large animal keeping in the area as it was a permitted use in the fomrerly designated Agricultural zone. Site: The existing land use is residential. There is one single - family dwelling on the site, along with accessory structures. The proposed land uses are residential and those uses permitted in the underlying zone. North: The land north of the site is presently undeveloped and vacant. Agricultural activities were pursued in the past and there may be small scale crops that are currently harvested. South: The area south of the proposal is predominantly residential with single - family lots. The lots adjacent to Wellesley Avenue are larger half acre to one acre lots with platted areas further south consisting of smaller lots of 7,000 to 10,000 square feet. Fast: The land lying east of the proposal is largely residential with lot sizes of approximately 11,000 square feet. Hendrickson Subdivision, a 20 lot subdivision, lies adjacent to the proposal on the east property line and features typical lot sizes of 80'X136'. The Trentwood Elementary schoolgrounds lie east of the site on Wellesley, which contain recreation facilities. West: The area to the west is residential with approximately 20,000 square foot lots. A 10 lot subdivision, Alexander's Subdivision is located adjacent to the proposal on the west and contains 10 lots with typical lot sizes of 95'X216'. Further along Wellesley, where Wellesley connects with Upriver Drive is the Spokane River, Centennial Trail, and Plante's Ferry Park. G . Circulation: Access to the proposed subdivision is from Wellesley Avenue. Direct access from lots to Wellesley is not permitted. Internal access will be from 4/93 HEC Staff Report for PE- 1697 -93 Page 88 Best Road. Best Road will be constructed with a temporary cul -de -sac with a 50 foot right of way, which includes 36 feet of paving with curb. There is a 25 feet unimproved half (1/2) right of way along the north property line of this site. It may be constructed in the future to provide connection to the existing subdivision east of the subject site which also has a east/west 1/2 right -of -way. The County Engineer is requesting 25 feet of dedication for this 1/2 right of way. H . Design: All lots within the proposed subdivision are rectangular in design and have frontage on a public right of way. Many of the lots just meet the minimum lot size of 10, 000 square feet required in the Urban Residential -3.5 (UR -3.5) zone. If any lots do not meet the minimum 10,000 square feet requirement at final plat submittal, the sponsor will be required to apply for an administrative exception for a deviation from the minimum lot standards, or adjust the lot lines to comply with with the zoning standards. The proposal has limitations as to lot depths because of the narrow width of the parcel. The public road creates the need for a 50 foot width right -of -way and therefore creates lot depths of 104 feet and 87 feet. Building setbacks create limited building area on the smaller lots. 1. Preliminary Plat Data Building Setbacks: Proposed Required Front yard 30 feet 30 feet Flanking yard 25 feet 25 feet Side yard 5 feet @ story 5 feet @ story Rear yard 20 feet 20 feet NOI'E: The existing structures on the 2, Block 1 and Lot 4, Block 1 will have non - conforming setbacks. Other Site Plan Considerations: The preliminary plat submitted for review indicates a 25 foot setback from the future acquisition area (FAA). The Comprehensive Plan recommends a setback of 35 feet from Principal Arterials. I. Density: The proposed net density is 3.9 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. K. Power Transmission Lines /Other Known Easements: Final plat process requires disclosure of all recorded easements. L . Water Supply: The proposal is within the Trentwood Irrigation Water District. The sponsor will be required to satisfy water district conditions prior to final plat approval. 4/93 1i1EC Staff Report for PE- 1697 -93 Page 89 M Sewage Disposal: Sewage disposal shall be accomplished by individual on- site systems. The sponsor will be required to double -plumb and install dry line sewer for future hook -up to a public sewer system. N . School: The proposal is in the East Valley School District No. 361. No comments were received by the school district. O. Fire Protection: The proposal is within Fire District No. 1 . The Fire District and the Division of Buildings Department (Fire Marshall) are required to approve fire protection provisions prior to finalizing the preliminary plat. P . Wetlands: Spokane County Wetland Inventory Maps do not indicate any wetlands on the site. The site is associated with an area of special flood hazard. The regulations of the National Flood Insurance Program may be applicable to this proposal. The County Engineer has included in its conditions of approval provisions for these regulations with the final plat review process. Q. Cultural Resources: None have been identified. R . Special Information: This parcel presently has preliminary short plat approval (SP- 730 -91). Upon approval of this preliminary plat, SP- 730 -91 will become null and void. 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 Nonsignificance ( "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 April 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 1- Iearing Examiner may consider additional environmental related testimony at the public hearing. IV.
