FINDINGS OF FACT 1. The individual signing below has been properly delegated the responsibility for rendering this decision by the Director of the Spokane County Division of Planning. 2. The original development proposal was to divide approximately 69.6 acres into 153 lots for single family residences. 3. The subject preliminary plat was approved by the Board of County Commissioners on January 29, 1993. 4. The proposal is generally located south of and adjacent to 16 Avenue, approximately 900 feet east of Sullivan Road in Section 25, Township 25 N., Range 44 EWM, Spokane County, Washington. 5. The existing zoning of the property described in the application is Urban Residential -3.5 (UR -3.5), established on January 1, 1991, consistent with the Program to Implement the Spokane County Zoning Code. Pursuant to RCW 58.17.195 the proposal does conform to the requirements of the existing Urban Residential -3.5 (UR -3.5) zone. 5cott n 6. The Comprehensive Plan designates this area of the preliminary plat as Urban (U) and the location is inside the Priority Sewer Service Area (PSSA). The Comprehensive Plan designation remains the same since the original preliminary plat approval. 7. The subject property is located inside of the Interim Urban Growth Area (IUGA) adopted by the Board of County Commissioners (BOCC) Resolution #97 -0321. 8. Spokane County has established specific criteria for considering the extension of time for the expiration of preliminary subdivisions, specifically for regular subdivisions, and department policy for short subdivisions. These criteria are found in Section 12.100.118 (Extensions of Time) of the Spokane County Subdivision Ordinance and have been used as a basis for this decision. Section 12.100.118 states that "The Director may administratively approve an extension provided there are no significant changed conditions which would render filing of the plat or binding site plan contrary to the public health, safety or general welfare, and further provided one or more of the following circumstances is found to apply." 1) That some portion of the existing preliminary plat has been finalized since the last extension was granted and the remaining lots would form a unified development consistent with the original approval; Extension Time Findings • ■ File No. PE- 1684 -92 Page 2 RESPONSE: Nine (9) phases of the preliminary plat have been finalized to date and recorded with the County Auditor. The 9 phase was recorded in the County Auditor's Office in March of 2000. 2) That the preliminary subdivision, short subdivision, or binding site plan remains generally consistent with the original plat or binding site plan that was approved, and the sponsor has taken substantial steps towards finalizing the plat or binding site plan, which shall include one, but is not limited to, the following: a. surveying the lots within the development; b. arranging for public services to the site; c. obtaining necessary financing for all or a portion of the preliminary subdivision, short subdivision, or binding site plan; d. the completion of studies or other requirements which were part of preliminary subdivision, short subdivision, or binding site plan approval. RESPONSE: The preliminary subdivision remains consistent with the original plat that was approved. In addition, the applicant has finalized 146 of the originally approved lots, with 7 lots on 2.65 acres remaining. Those 146 lots have been surveyed and connected to public sewer. 3) That at the time the preliminary plat approval was granted, development of the proposal was conditioned upon the extension of public services which are not yet available. This provision shall not apply to public utility extension which the project sponsor would normally fund. RESPONSE: Not applicable. 4) That administrative delays have caused the inability of the applicant to finalize the plat within the five (5) year time period. REPSONSE: Not applicable. 9. This is the fourth request for a time extension. The total life of the preliminary plat has been approximately eight (8) years. 10. The proposal has been circulated to all affected agencies and departments for comment. Additional and /or revised conditions of approval have been recommended by the Spokane County Division of Engineering and Roads. The recommended conditions of approval are included below. CONCLUSIONS BASED UPON A REVIEW of (a) the criteria for approving an extension of time of the expiration date for a preliminary plat and (b) the above Findings of Fact, the following conclusion is made: The proponent has demonstrated progress toward completing the preliminary plat as evidenced in the above Findings of Fact and there are no significant changed conditions which would render filing of the plat contrary to the public health, safety or general welfare. Therefore, a one (1) year extension of time is warranted.

Construction within the proposed public streets and easements shall be performed under the direct supervision of a licensed engineer /surveyor, who shall furnish the County Engineer with "as- built" plans and a certificate in writing that all improvements were installed to the lines and grades shown on the approved construction plans and that all disturbed monuments have been replaced. 5. No construction work is to be performed within the existing or proposed public right -of -way until a permit has been issued by the County Engineer. All work is subject to inspection and approval by the County Engineer. 6. All construction within the existing or proposed public right -of -way is to be completed prior to filing each final plat, or a bond in the amount estimated by the County Engineer to cover the cost of construction of improvements, construction certification, "as- built" plans and monumenting the street centerlines shall be filed with the County Engineer. 7. No direct access from lots to one -half (1/2) rights -of -way until such roads are constructed to County Standards and established as County Roads. 8. No direct access from lots to Stub Road connections until such roads are constructed to County Standards and established as County Roads. 9. Road design, construction and drainage control for 1/2 right -of -way and stub road connections are the responsibility of the developer. 10. Appropriate provision shall be made that the following- described property be held in trust until the continuation of the streets be dedicated or deeded: a one (1) -foot strip at the Extension of Time Findings File No. PE- 1684 -92 Page 6 ends or edges of all streets that terminate or border the subdivision boundary.

Following plan acceptance by the Spokane County Engineer, drainage language will be drafted by Spokane County and provided to the Sponsor's Engineer or Surveyor for inclusion with the final plat document. 25. Before the street and stormwater plans are submitted to Spokane County for review and acceptance, a Design Deviation must be submitted to Spokane County for any non- standard elements of the project plans. The sponsor shall acquire approval of the Design Deviation from the County Engineer before construction plans are submitted for review. The Design Deviation request must include adequate engineering justification and drainage calculations, and should include any other agency approvals that may be necessary for the proposed deviation to work as designed. The Design Deviation request shall include a description of maintenance responsibilities. The applicant shall make provision for the perpetual maintenance of any drainage facilities located outside of the public right -of -way. The Spokane County Engineer may deny a Design Deviation or he may impose conditions of approval on the Design Deviation. 26. Adequate drainage easements, granted to Spokane County and /or an acceptable maintenance entity, must be provided for all elements of the drainage plan, in order that proper maintenance may be performed. A Homeowners Association has been proposed for this development. Easements for drainage ditches and natural drainage channels shall be wide enough to contain within the easement the runoff from a 50 year, 24 hour storm event. for the contributing basin, plus a 30% freeboard. The easement shall also include an adequate maintenance access for the drainage course. Any easements and agreements for acceptance, conveyance, treatment, and disposal of stormwater that lie outside of the proposed plat being submitted, must be submitted with the project plans before Spokane County will review the plans for acceptance. Grassed percolation swales larger than 1,200 square feet must be placed in separate tracts that will be maintained by the homeowners association unless a design deviation is granted and shall meet the requirements contained in the Guidelines for Stormwater Management. 27. Maintenance access roads of sufficient width shall be provided to all ditches, ponds, drainage control structures, and any element of the system that may require replacement or maintenance in the future. Easements for drainage ditches shall be a minimum of 20 ft. in width. Extension of Time Findings File No. PE- 1684 -92 Page 8 28. All maintenance access roads shall have a minimum of six inches of gravel, or other type of all- weather driveable surface acceptable to the County Engineer. The maintenance access road shall be designed to accommodate the turning movements of a Bus as defined by AASHTO. If the maintenance road is greater than 300 feet in length, measured from the connecting public roadway or paved private road, than a turn - around shall be provided at its terminus. 29. If the drainage disposal system includes infiltration of stormwater as an element in design, there shall be a site investigation and study conducted by a qualified Geotechnical Engineer prior to final submittal of road and drainage plans that evaluates the potential impacts on surrounding properties, foundations, basements and structures of injecting and infiltrating stormwater and also the affects of imported water for lawn watering. If it is determined that negative impacts are probable, than mitigative measures shall be recommended by the geotechnical engineer and implemented by the applicant. The geotechnical report shall cover all sites where drywells may be proposed. The report shall draw conclusions about the ability of the proposed drywells to function according to the Spokane County Guidelines for Stormwater Management. The site investigation shall also verify if the soils can infiltrate the stormwater at the minimum rate of 0.5 inches per hour for any proposed grassed percolation areas. If the minimum requirement can not be met, an alternative stormwater design will need to be submitted 30. If the project is developed in phases, a phased road and drainage plan shall be prepared by a licensed Professional Engineer, which clearly shows the phasing of the development. The plan must demonstrate that each phase of the development is in conformance with the applicable Spokane County road and drainage standards, and the Conditions of Approval for the plat as well as any applicable regulations that may apply to this project from other governmental authority. The stormwater management systems and roads for this plat shall be constructed and certified to be constructed in accordance with the accepted road and drainage plans, or all the required improvements must be bonded for in accordance with Spokane County regulations, prior to the recording of the final plat. Record drawings and all construction documentation shall be submitted with the proper certification statement. 31. Erosion Control: A Temporary Erosion and Sedimentation Control (TESC) plan is to be prepared by a WA State licensed Professional Engineer, and implemented throughout the duration of construction. The TESC plan is to be prepared using best management practices (BMP's) currently accepted within the Civil Engineering profession, and shall address limits on amount and duration of disturbed areas, which have not been stabilized. The TESC plan is to include, as a minimum, a grading plan, location and details of silt control structures, and street cleaning program. Filter runoff from exposed areas prior to discharging into a detention pond, 208' swale, or infiltration facility. The TESC plan is to be included in the road and drainage plans. The applicant's Engineer is to submit the TESC plan and supporting calculations to Spokane County for review, and shall receive acceptance as part of the plan review process prior to site disturbance. The TESC major structures (such as silt ponds, silt traps) are to be installed prior to other site work and the TESC measures are to be implemented and maintained throughout the duration of construction, including house construction. 32. The sponsor's Engineer shall properly consider and include all applicable mitigation measures, that may be identified in any accepted geo- hazard report for this project, in his final design plans for this project. 33. If the project is phased and one phase depends on another phase for access and /or drainage treatment and disposal, the prior phase shall be completed and certified prior to Extension of Time Findings File No. PE- 1684 -92 Page 9 the submittal of plans for the dependent phase of the development. One foot no access strips on public roads will not be released until the subject phase is completed, certified and accepted by Spokane County for maintenance. No access through a non certified and non - accepted phase of the development may be allowed and no plans will be accepted by Spokane County for construction unless the prior phase is completed and certified by the Sponsor's Engineer. 34. A bond for the anticipated engineering inspection and certification portion of the project shall be posted with the County Engineer prior to plan acceptance. 35. The drainage system outside of the public right -of -way will neither be maintained nor operated by Spokane County forces unless specifically approved by the Spokane County Engineer. Prior to plan acceptance by the County Engineer, the Sponsor shall provide a mechanism, acceptable to the County Engineer, for the perpetual maintenance of the stormwater drainage system. This mechanism shall also provide for the funding of routine maintenance and the replacement of the various components of the drainage system at the end of the service life of the respective components, and any other improvements that may be legally required in the future. An Operations and Maintenance Manual for any non - standards portions of the stormwater management system shall be prepared by the Sponsor's Engineer, and included in the project documents submitted to the County Engineer for acceptance, along with a discussion of the design life of the various components, a calculated annual cost for repair and maintenance, and a calculated replacement cost. Homeowners associations are accepted by the Spokane County Engineer for carrying out the required maintenance functions and responsibilities. 36. This proposed subdivision or development proposal is located within a drainage basin which has been identified by the Spokane County Engineer's and Utilities offices as having stormwater runoff problems. Since this proposed subdivision or development proposal is affected by or is a contributor to stormwater flows, property owners should participate in the planning and implementation of a future basin wide stormwater management system. The following statement shall be placed in the plat dedication: "The owner(s) or successor(s) in interest agree to join in any County- approved stormwater management program and to pay such rates and charges as may be fixed through public hearings for service or benefit obtained by the planning, design, constructing, maintaining or operation of stormwater control facilities."

The proposal is generally located south of and adjacent to 16 Avenue, approximately 900 feet east of Sullivan Road in Section 25, Township 25 N, Range 44 EWM, Spokane County, Washington. 5. The existing zoning of the property described in the application is Urban Residential -3.5 (UR -3.5), established on January 1, 1991, consistent with the Program to Implement the Spokane County Zoning Code. Pursuant to RCW 58.17.195 the proposal does conform to the requirements of the existing Urban Residential -3.5 (UR -3.5) zone. 6. The Comprehensive Plan designates this area of the preliminary plat as Urban (U) and the location is inside the Priority Sewer Service Area (PSSA). The Comprehensive Plan designation remains the same since the original preliminary plat approval. 7. The subject property is located inside of the Interim Urban Growth Area (IUGA) adopted by the Board of County Commissioners (BOCC) Resolution #97 -0321. 8. Spokane County has established specific criteria for considering the extension of time for the expiration of preliminary subdivisions, specifically for regular subdivisions, and department policy for short subdivisions. These criteria are found in Section 12.100.118 (Extensions of Time) of the Spokane County Subdivision Ordinance and have been used as a basis for this decision. Section 12.100.118 states that "The Director may administratively approve an extension provided there are no significant changed conditions which would render filing of the plat Extension of Time Findings File No. PE- 1684 -92 Page 2 contrary to the public health, safety or general welfare, and further provided one or more of the following circumstances is found to apply." 1) That some portion of the existing preliminary plat has been finalized since the last extension was granted and the remaining lots would form a unified development consistent with the original approval; RESPONSE: Nine (9) phases of the preliminary plat have been finalized to date and recorded with the County Auditor. The 9th phase was recorded in the County Auditor's Office in March of 2000. 2) That the preliminary subdivision, short subdivision, or binding site plan remains generally consistent with the original plat or binding site plan that was approved, and the sponsor has taken substantial steps towards finalizing the plat or binding site plan, which shall include one, but is not limited to, the following: a. surveying the lots within the development; b. arranging for public services to the site; c. obtaining necessary financing for all or a portion of the preliminary subdivision, short subdivision, or binding site plan; d. the completion of studies or other requirements which were part of preliminary subdivision, short subdivision, or binding site plan approval. RESPONSE: The preliminary subdivision remains consistent with the original plat that was approved. In addition, the applicant has finalized 146 of the originally approved lots, with 7 lots on 2.65 acres remaining. Those 146 lots have been surveyed and connected to public sewer. 3) That at the time the preliminary plat approval was granted, development of the proposal was conditioned upon the extension of public services which are not yet available. This provision shall not apply to public utility extension which the project sponsor would normally fund. RESPONSE: Not applicable. 4) That administrative delays have caused the inability of the applicant to finalize the plat within the five (5) year time period. REPSONSE: Not applicable. 9. This is the third request for a time extension. The total life of the preliminary plat has been approximately seven (7) years. 10. The proposal has been circulated to all affected agencies and departments for comment. Additional conditions of approval have been recommended by the Spokane County Division of Engineering and Roads. The recommended conditions of approval are included below.

Argonne, Spokane, WA 99212 File if • BEFORE SPOKANE COUNTY DIVISION OF BUILDING & PLANNING IN THE MATTER OF AN EXTENSION OF TIME REQUEST FOR PE- 1684 -92, RIDGEMONT ESTATES NORTH, AN APPROVED PRELIMINARY PLAT FINDINGS OF FACT CONCLUSIONS AND DECISION THIS MATTER, a request for an extension of time from Kenneth J. Tupper has been received and decided upon, pursuant to Spokane County Subdivision regulation (Chapter III, Section G) and RCW 58.17.140. FINDINGS OF FACT AND CONCLUSIONS 1. The individual signing below has been properly delegated the responsibility for rendering this decision by the Spokane County Director of Building and Planning. 2. The proposal consists of a preliminary plat to subdivide approximately 69.6 acres into one hundred and fifty-three (153) lots for single - family residences. 3. The subject preliminary plat was approved by the Hearing Examiner Committee (HEC) on January 29, 1993. 4. The proposal is generally located south of and adjacent to 16`" Avenue and approximately 900 feet east of Sullivan Road in Section 25, Township 25 North, Range 44 E.W.M. Spokane County, Washington. 5. The existing zoning of the property described in the application is Urban Residential 3.5 (UR 3.5), established on January 1, 1991 consistent with the Program to Implement the Spokane County Zoning Code. Pursuant to RCW 58.17.195 the proposal does conform to the requirements of the existing Urban Residential 3.5 (UR 3.5) zone. 6. The Comprehensive Plan designates this area of the preliminary plat as Urban and the location is within the Priority Sewer Service Area. The Comprehensive Plan designation remains the same since the original preliminary plat approval. 7. Spokane County has established specific criteria for considering the extension of time for the expiration of preliminary subdivisions, specifically for regular subdivisions, and department policy for short subdivisions. These criteria are found in Chapter III Section G of the Spokane County Subdivision Ordinance and have been used as a basis for this decision. Section G states, "Approval of a preliminary subdivision shall automatically expire three years after preliminary approval is granted unless a time extension is applied for." and follows with "Upon application for time extension , the Division of Building and Planning Director or designee may administratively approve extensions for up to three (3) year periods provided at least one of the following circumstances is found to apply:" The following are the relevant sections of Section G and the Division of Building and Planning response: 1. That some portion of the existing preliminary plat has been finalized since the last extension was granted and the remaining lots would form a unified development consistent with the original approval; RESPONSE,: Four phases of the original preliminary plat encompassing 64 lots have been finalized and recorded with the County Auditor. 2. That the preliminary plat as approved remains consistent with the Generalized Comprehensive Plan for Spokane County insofar as density AND other development RECEIVED JUN 0 3 1996 ILYieeerillg Extension of Time Findings provisions apply, and the sponsor has taken substantial steps towards finalizing his plat, which shall include but not be limited to: a. surveying the lots within the development, b. arranging for public services to the site, c. obtaining necessary financing for all or a portion of the preliminary plat, d. the completion of studies or other requirements which were part of preliminary plat approval; RESPONSE: The Applicant has finalized 64 Lots of a total of 153 approved lots on approximately 25 acres of the original 69.6 acres. Those 64 lots have been surveyed and connected to public sewer. 3. That at the time preliminary approval was granted, development of the proposal was conditioned upon the extension of public services which are not yet available This provision shall not apply to public utility extension which the project sponsor would normally fund. RESPONSE.: NA File No. PE- I684 -92 Page 2 8. No additional conditions have been recommended by the County Health District, County Utilities and the County Division of Engineering and Roads. The Central Valley School District has responded to the request for extension of time (See letter dated April 8, 1996) and has requested that the County deny the request or condition the approval of the request contingent upon the applicant agreeing to mitigate the impacts of the proposal. 9. This is the first request for a time extension. The total life of the preliminary plat has been approximately three (3) years. The request for time extension was received February 7, 1996. 10. The applicant/owner should show substantially greater progress toward complying with Chapter III, Section G, of the Subdivision Ordinance before requesting an additional extension of time. 11. Subsequent extension of time will only be considered upon a finding of substantial compliance with Chapter III, Section G, of the Subdivision Ordinance; otherwise the preliminary subdivision approval will become null and void. DECISION BASED UPON THE ABOVE Findings of Fact and Conclusions, an extension of time request for application PE- 1684 -92 is hereby APPROVED until June 1, 1999.

Hohman, P.E. PROPOSED CONDITIONS OF APPROVAL FOR RIDGEMONT ESTATES NORTH TIME EXTENSION 5-31-01 PROJECT # P -1684 I. A Professional Engineer, licensed in the State of Washington, shall submit final road and drainage plans, a drainage report and road and drainage calculations that conform to the April 3, 2001 Edition of the Spokane County Standards for Road and Sewer Construction and the current edition of the Spokane County Guidelines for Stormwater Management and the revised conditions of approval. Final road and drainage plans shall also comply with all applicable county, state and federal laws, ordinances, and interim official controls that are applicable to this project. Final road and drainage plans, related calculations and a drainage report shall receive the County Engineer's acceptance prior to release of a construction or building permit or approval of the final plat. Following plan acceptance by the Spokane County Engineer, drainage language will be drafted by Spokane County and provided to the Sponsor's Engineer or Surveyor for inclusion with the final plat document. 2. Before the street and stormwater plans are submitted to Spokane County for review and acceptance, a Design Deviation must be submitted to Spokane County for any non - standard elements of the project plans. The sponsor shall acquire approval of the Design Deviation from the County Engineer before construction plans are submitted for review. The Design Deviation request must include adequate engineering justification and drainage calculations, and should include any other agency approvals that may be necessary for the proposed deviation to work as designed. The Design Deviation request shall include a description of maintenance responsibilities. The applicant shall make provision for the perpetual maintenance of any drainage facilities located outside of the public right -of -way. The Spokane County Engineer may deny a Design Deviation or he may impose conditions of approval on the Design Deviation. 3. Adequate drainage easements, granted to Spokane County and /or an acceptable maintenance entity, must be provided for all elements of the drainage plan, in order that proper maintenance may be performed. A Homeowners Association has been proposed for this development. Easements for drainage ditches and natural drainage channels shall be wide enough to contain within the easement the runoff from a 50 year, 24 hour storm event. for the contributing basin, plus a 30% freeboard. The easement shall also include an adequate maintenance access for the drainage course. Any easements and agreements for acceptance, conveyance, treatment, and disposal of stormwater that lie outside of the proposed plat being submitted, must be submitted with the project plans before Spokane County will review the plans for acceptance. Grassed percolation swales larger than 1,200 square feet must be placed 1 in separate tracts that N. be maintained by the homeowner, sociation unless a design deviation is granted and shall meet the requirements contained in the Guidelines for Stormwater Management. 4. Maintenance access roads of sufficient width shall be provided to all ditches, ponds, drainage control structures, and any element of the system that may require replacement or maintenance in the future. Easements for drainage ditches shall be a minimum of 20 ft. in width. 5. All maintenance access roads shall have a minimum of six inches of gravel, or other type of all- weather driveable surface acceptable to the County Engineer. The maintenance access road shall be designed to accommodate the turning movements of a Bus as defined by AASHTO. If the maintenance road is greater than 300 feet in length, measured from the connecting public roadway or paved private road, than a turn - around shall be provided at its terminus. 6. If the drainage disposal system includes infiltration of stormwater as an element in design, there shall be a site investigation and study conducted by a qualified Geotechnical Engineer prior to final submittal of road and drainage plans that evaluates the potential impacts on surrounding properties, foundations, basements and structures of injecting and infiltrating stormwater and also the affects of imported water for lawn watering. If it is determined that negative impacts are probable, than mitigative measures shall be recommended by the geotechnical engineer and implemented by the applicant. The geotechnical report shall cover all sites where drywells may be proposed. The report shall draw conclusions about the ability of the proposed drywells to function according to the Spokane County Guidelines for Stormwater Management. The site investigation shall also verify if the soils can infiltrate the stormwater at the minimum rate of 0.5 inches per hour for any proposed grassed percolation areas. If the minimum requirement can not be met, an alternative stormwater design will need to be submitted 7. If the project is developed in phases, a phased road and drainage plan shall be prepared by a licensed Professional Engineer, which clearly shows the phasing of the development. The plan must demonstrate that each phase of the development is in conformance with the applicable Spokane County road and drainage standards, and the Conditions of Approval for the plat as well as any applicable regulations that may apply to this project from other governmental authority. The stormwater management systems and roads for this plat shall be constructed and certified to be constructed in accordance with the accepted road and drainage plans, or all the required improvements must be bonded for in accordance with Spokane County regulations, prior to the recording of the final plat. Record drawings and all construction documentation shall be submitted with the proper certification statement. 8.

The TESC plan is to be prepared using best management practices (BMP's) currently accepted within the Civil Engineering profession, and shall address limits on amount and duration of disturbed areas, which have not been stabilized. The TESC plan is to include, as a minimum, a grading plan, location and details of silt control structures, and street cleaning program. Filter runoff from exposed areas prior to discharging into a detention pond, 208' swale, or infiltration facility. The TESC plan is to be included in the road and drainage plans. The applicant's Engineer is to submit the TESC plan and supporting calculations t ,tokane County for review, and shai :eive acceptance as part of the plan review process prior to site disturbance. The TESC major structures (such as silt ponds, silt traps) are to be installed prior to other site work and the TESC measures are to be implemented and maintained throughout the duration of construction, including house construction. 9. The sponsor's Engineer shall properly consider and include all applicable mitigation measures, that may be identified in any accepted geo- hazard report for this project, in his final design plans for this project. 10. If the project is phased and one phase depends on another phase for access and/or drainage treatment and disposal, the prior phase shall be completed and certified prior to the submittal of plans for the dependent phase of the development. One foot no access strips on public roads will not be released until the subject phase is completed, certified and accepted by Spokane County for maintenance.

GENERAL INFORMATION II. SITE INFORMATION PLANNING DEPARTMENT REPORT ' TO: SPOKANE COUNTY HEARING EXAMINER COMMITTEE FROM: CURRENT PLANNING SECTION DATE: JANUARY 21, 1993 SUBJECT: PRELIMINARY PLAT OF RIDGEMONT ESTATES NORTH, PE- 1684 -92, WITH EXISTING URBAN RESIDENTIAL -3.5 (UR -3.5) ZONING WITHIN THE AQUIFER SENSITIVE AREA (ASA) OVERLAY ZONE. Applicant: Sullivan South c/o Ken Tupper 12929 East Sprague Spokane, WA. 99216 (509) 928-1991 Surveyor: Charles E. Simpson N. 909 Argonne Spokane, WA. 99212 (509) 926-1322 Contact Planner: William J. Moser Location: Generally located south of and adjacent to 16th Avenue and approximately 900 feet east of Sullivan Road in Section 25; Township 25 N., Range 44 EWM, Spokane County, Washington. Proposal: 153 single family residential Tots and two lots to be used for utility and drainage purposes and those uses allowed in the Urban Residential -3.5 (UR -3.5) zone. A. Site Size: 69.6 acres. Gross Density: 2.2 units per acre B . Comprehensive Plan 1 . Land Use Plan: The property is located within the Urban category and is within the Aquifer Sensitive Area (ASA) Overlay zone. The Urban category is intended to provide the opportunity for development of a "city- like" 1/93 HEC Staff Report for PE- 1684 -92 Page 37 environment which includes various land uses, intensive residential development and public facilities and services (water, sanitary and storm sewer lines, police and fire protection, and other features). Fill in development is encouraged. Residential net densities should have an approximate density of 1 unit per acre to 17 units per acre. This proposal is consistent with these density guidelines. When reviewing new developments, the Comprehensive Plan states: Goal 1.1 "Encourage a variety of housing types and densities." Objective 1.1a "Promotes fill -in within established development areas having adequate power supplies, water, sanitary sewers, streets ..." The proposed plat does conform to the Urban Comprehensive Plan Goals and Objectives for fill -in development. The overall gross density of 2.2 units per acre is within the Comprehensive Plan guidelines. 2 . Arterial Road Plan: The proposal is adjacent to 16th Avenue. The Spokane County Arterial Road Plan designates 16th Avenue as a Minor Arterial with an existing width of 60 feet and a planned width of 80 feet. In order to implement the plan, the County Engineer has required that 10 feet be set aside as future acquisition area. Structure setbacks will be measured from the future acquisition area and the Comprehensive Plan additionally recommends a 35 foot setback along arterials. C . Site Characteristics: The site has been used for agricultural production. There is an existing home site located on the southeastern portion of the site with associated agricultural accessory buildings. The site is bisected by a slight ridge that runs from the southwest to the northeast. Generally, the site drops in elevation from the northwest portion of the site to the southeast portion. The southeast border of the site, is at the base of a bluff. To the east of this bluff (outside of this proposal) is Ridgemont Estates and Ridgemont Estates No. 2 final plats that have been developed with single family dwellings. D. Neighborhood Characteristics: This area has experienced substantial residential development activities in recent years. The majority of the area has been platted and developed at a density similar to the proposal. Rotchford Acre Tracts on the north side of 16th Avenue is the exception with regards to density with lots of one acre per dwelling. This subdivision was platted in 1974. There are still some isolated larger tracts of land in the area used for agriculture and animal keeping. The unplatted area contained on this site is the largest undeveloped parcel in the immediate area. 1/93 HEC Staff Report for PE- 1684 -92 Page 38 E. Zoning Analysis: Proposal: North: South: Fast West: Fast West: Subdivide land presently zoned Urban Residential -3.5 (UR -3.5) zoning established in 1991. Suburban Residential -1 (SR -1) established in 1991, (Rotchford Acre Tracts). Urban Residential -3.5 (UR -3.5) established in 1991. Urban Residential -3.5 (UR -3.5) established in 1991. Urban Residential -3.5 (UR -3.5) established in 1991. F. Land Use Analysis: Site: The existing land use is agricultural with an existing dwelling and accessory structures. The proposed land uses are 153 single family residential lots and two (2) utility lots uses for drainage purposes and a sewage lift station. North: Rotchford Acre Tracts with typical lots of one acre. South: Additions to Ridgemont Estates No. 4 with lots of 10,000 square feet and larger. Ridgemont Estates No. 2 and Ridgemont Estates with lots of 15,000 square feet and larger. Adjacent west at the southeast corner of Sullivan Road and 16th Avenue, is a 15 acre parcel owned by the Seventh Day Adventist Church and; additions to Ridgemont Estates No. 4 with lots of 10,000 square feet or larger. The proposal generally provides lots of 10,000 square feet and along 16th Avenue are increased to 1/2 acre to provide compatibility with existing adjacent lot sizes to the north. G . Circulation: The proposal is adjacent to 16th Avenue with 14 lots having direct access to 16th Avenue. The applicant proposes circular driveways for these Tots to allow vehicles to enter 16th Avenue without backing onto 16th Avenue. Three public roads access the plat off of 16th Avenue, Timberlane Road, Rotchford Road, and 20th Avenue. Timberlane Road on the east boundary of the proposal will connect from 16th Avenue, through Ridgemont Estates No. 4 Additions to the south, to 24th Avenue. This will provide a north -south connection between 16th Avenue and 24th Avenue. Twentieth Avenue which was established in Ridgemont Estates No. 4 will provide access from Sullivan Road through this proposal in a northeasterly direction to 16th Avenue. 1/93 HEC Staff Report for PE- 1684 -92 Page 39 Rotchford Road will align with Rotchford Drive on the north side of 16th Avenue and connect from 16th Avenue to proposed 20th Avenue in the plat. Sonora Road, established in Ridgemont Estates No. 4, will extend northward through the site. There is a loop road which will serve interior lots that connects to Sonora Road on the east side of Sonora Road. There are five (5) interior cul -de -sacs within the proposal that will provide access for 16 lots. Two (2) lots are proposed to be served by private driveways from public roads, Lot 4 of Block 8 and Lot 12 of Block 8. H . Design: Preliminary plat illustrates 153 residential lot and two (2) lots for utilities and drainage. Residential lots will be at a minimum of 10,000 square feet with 80 feet of street frontage. There are 14 lots fronting on 16th Avenue that will be approximately 1/2 acre in size with approximately 150 feet of street frontage. These lots will provide a lot size transition from the 10,000 square foot lots in the proposal to the one acre lots in Rotchford Acre Tracts on the north side of Sixteenth Avenue which also have 150 feet or more of street frontage. The applicant states that duplexes will be prohibited on these 1/2 acre lots. Normally, duplexes are allowed on lots of 20,000 square feet in the Urban Residential-3.5 (UR -3.5) zone. Lots fronting on 16th Avenue will also have circular driveways to access 16th Avenue. Plat design utilizes the ridge that bisects the site by placing 20th Avenue road access on the upper end of the lots. Lot 4 of Block 8 and Lot 12 of Block 8 are proposed to be served by private driveways extending from public road. There will be a required 25 foot structure setback from the edge of these private drives. This setback will need to be taken into consideration when calculating buildable area on lots affected by these setbacks. Lot 4 of Block 8 contains an existing homesite with a dwelling and accessory structures. Lot 10 of Block 8 shows an existing accessory structure within the lot. This structure will have to be removed or incorporated into the lot with the existing dwelling as the primary use on any lot has to be residential. It does not appear this is adequate area for this structure and a dwelling on this lot. There is also an accessory structure noted as "to be removed" on lots 13 and 14 of Block 8. Lot 6 of Block 8 is a utility lot of approximately 1/2 acre proposed to be used as a sewage lift station. The Spokane County Utilities Department requires that this lot be dedicated to Spokane County. Lot 23 of Block 5 is a lot of approximately 11 acres to be used for drainage. This area is the lowest elevation of the site and is located in the northeast corner of the site. Specific utilization of this drainage area is to be determined by the County Engineer Department when drainage plans are finalized. H . Density: The net density is 3.2 units per acre. 1/93 HEC Staff Report for PE- 1684 -92 Page 40 I. J. Drainage: A drainage plan is required. This plan must be reviewed and approved by the County Engineer's Department prior to final plat. Water Supply: The proposal is within the Vera Water District. A water plan is required prior to finalization of any portion of the plan. K . Sewage Disposal: The proposal will connect to public sewer as per requirement of the County Utilities. - L. School: The proposal is in the Central Valley School District No. 356. M. 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. N . Cultural Resources: None have been identified. O. Parks and Recreation: The closest park is Terrace View located at 24th Avenue and Blake Road (13525 E. 24th Avenue). Terrace View is a nine (9) acre park featuring play equipment, a ball field and a swimming pool. P . History: The northwest portion of this site is currently included in the preliminary plat of Ridgemont Estates No. 4, PE- 1423 -82. Specifically, 45 acres of the Ridgemont Estates North proposal already has preliminary approval for 81. Lots as part of PE- 1423 -82. Upon approval of this proposal, PE- 1684 -92, that portion of PE- 1423 -82, that exists on this site will become null and void. PE- 1423 -82 is a preliminary plat approval for 284 lots on 125 acres. To date 86 lots have been finalized. The Spokane County Planning Department is currently reviewing an Extension of Time Application for PE- 1423 -82. 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 Nonsienificance ( "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 January 19, 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. 1/93 HEC Staff Report for PE- 1684 -92 Page 41 IV.

The project is on the gentler slopes at the base of the hill. It will be served with public sewer and public water. The streets will be paved and curbed. There are 62 lots in the plat. There are two pronounced and one secondary draw going through the project. These were formed by runoff from the flatter upper areas of the hill. In this study, we will assume that the upper area of the hill will be left undeveloped. Runoff coefficients will be adjusted accordingly. The purpose of this study is to identify various means of conveying and disposing of anticipated stormwater and snow melt runoff waters. Sizing for ditches, culverts, drywelis, and other conveyance and disposal structures will be determined by using the Rational Method of runoff calculation. Enclosed is a page of formulae and coefficients utilized to characterize the drainage basins related to the project. As you can see from the enclosed map (Exhibit "A ") there are 11 areas as defined by existing drainage basins and those formed in the platted area by paved and curbed streets intercepting natural drainage. We have chosen 10 year and 50 year storms in accordance with current accepted Spokane County,practice for design calculations. Drainage anticipated from areas above the plat will primarily be conveyed through the plat and disposed of in a constructed retention and seepage basin. The conveyance will be by ditch and culvert. Appropriate culvert sizes, ditch cross - sections, and inlet structures have been calculated. Runoff generated by improvements in the platted area will be disposed of by a combination of drywells and by curb and gutter conveyance to the ditches and culverts described in the previous paragraph.

V = 3 (73,000 + 50,000 +1(50,000)(73,000)) = 733,000 ft It is unlikely that heavy snow depth and deep frozen ground conditions would occur simultaneously. Usually, lack of snowfall permits frozen ground conditions, and heavy snow blankets decrease depth of frost. Assuming 12" of snow is a reasonable conservative estimate, since Spokane winter time snow depth average less than 6 ".* Culvert Calculations: 1. Assuming a 5% grade, and an inlet volume of 20 cfs, the culvert from 5A to 5B should be 18" dia. For a factor of safety, we will use 21" dia. culvert, cmp with an n of .015. 2. For the culvert at the intersection of Ridgemont Drive and Conklin Road, combined runoff for 50 year storm = 39 cfs. culvert slope = 0.081 cmp size required = 21 ", will use 24" for factor of safety. 3. For the culvert across Vera Crest Drive, north of Ridgemont Drive, runoff anticipated = 8.5 cfs, slope = .050 cmp size required = 12 + ", will use 18" cmq culvert for factor of safety. 4. 24" is also adequate for Vera Crest Drive from 8A to 10B. Since drywells will be placed in Uhilig silt loam and Lakeol silt loam, a disposal rate of 1'.0 cfs will be taken for standard double depth drywells. Ditches will never be less than 15% slope with 2 ft. depth and 10 ft. width.

Owners are willing to grant to che County perpetual easements, free of encumbrances and witn appropriate access, running through the Property in an alignment acceptable to the County, in considera- tion of the County paying all casts for the design and construc- tion of such Facilities. Owners and their successors hereby acknowledge an obligation to pay the County's General Facilities Charge L "GFC "), monthly service charges, and an In Lieu of Assessment charge IILA), as specified herein, upon connection of the Property, or future lots therein, to che Facilities. It is the intent of this Agreement to reduce to writing the Parties' agreement with respect to the conveyance of casements to the County, the design and construction of the Facilities, and related matters. Section 2: CAPITAL CONSTRUCTION The County shall be responsible for the design and construc- tion of the Facilities, generally described as 8", 10" and l;" sanitary sewer pipe, and necessary appurtenances thereto. The Facilities are deemed to be a benefit to the public. The design and construction of the Facilities will be in accordance with all applicable Federal, State and Local laws, ordinances, and regulations. The County shall install "Ts" at appropriate locations within the Facilities designated by Owners; however, the County shall not be obligated to install side sewer connection lines from the "Ts" to individual lots, which snail be the C..ners' responsibility to install. All manholes installed within the Facilities shall be designed and constructed to include a one foot I1') concrete ring section In order to facilitate adjustment of the manholes to a proper elevation at such time as roads are constructed within the Property. Page - 2 991 ICI 1135 Owners agree to grant to the County perpetual easements in the prope(cy, free of any encumbrances, along with temporary access easements thereto, all as specifically indicated on Attachment "B ", attached hereto and incorporated by reference' herein. Owners agree, within ten (10) days of written request by the County, to execute any and all necessary perpetual easement's), temporary construction easement permits, access easements, or any other documents required of Owners under the terms of this Agreement. Section 1: USE OF CONSTRUCTED SUBDIVISION SEWER FACILITY Only the Owners of the Property, or subsequent owners, and their successors, assigns or heirs, shall be permitted or author- ized under this Agreement, to tap into or use the Facilities. Owners shall be responsible for the design and construction of any other facilities on the Property, other than the Facilities to be constructed by the County as described herein, that may be necessary in order to use or connect to the Facilities, in conjunction with the subdividing of the Property. As owner of the Facilities, the County may allow, at Its sole discretion, other persons, firms or corporations outside the Property to tap into or use the Facilities. Additionally, as owner. the County will be responsible for maintenance and operation of the Facilities once constructed and accepted by the County. All users of the Facilities shall pay a monthly Main- tenance and Operation Fee as established by the Board of County Commissioners. Section 4: PAYMENT OF GFC AND ILA This section shall apply only to those residential lots which result from approved subdivision of the Property, and which are adjacent to the Facilities and connectable by side sewer thereto. The owner of each lot at the time of hook -up to the County's general sewerage system shall pay the County's General Faciltties Charge (GFC) that is current at that time, reduced by any County participation moneys then applicable to reduce said charge (the present GFC amount equals 2770.00 for residential properties, currently reduced by a forty percent (40%) County subsidy, leaving *462.00 payable by the property owner). Each lot owner at the time of hook -up shall also pay an In Lieu of Assessment charge 'ILA). This charge is deemed equivalent to the special benefit that the County's sewerage system is determined to provide to parcels of land within the most recent county ULID, reduced by applicable County participation moneys. Page - 1 Section 5: COMPLIANCE WITH LAWS The Parries hereto specifically agree to observe all federal, state and local laws, ordinances and regulations, including, but not necessarily limited to, chapter 49.60 RCW, to the extent that they may have any bearing on etcher providing any money under the terms of this Agreement or the services actually provided under the terms of this Agreement. .Section 6: MODIFICATION No modification or amendment of this Agreement shall be valid until the same Is reduced to writing and executed with the same formalities as this present Agreement. Page - 4 n bd ® n °- ' rn 66, ro kJ n M (Z 0 ca ;Ef: 994 ?Lc; 1136 Under this Agreement, the ILA payable at the time of hook -up shall be permanently fixed at *1,500.00 !the special benefit for residential parcels within a ULID is currently 22,500.00, which amount is currently reduced by a forty percent (40%) County subsidy, Leaving a balance of 11,500.00 payable). Each lot within the Property connecting directly, or indirectly, to the Facilities shall receive a credit of *700.00 against the ILA amount at the time of hook -up. This credit given by the County is In consideration of Owners' granting .to the County perpetual easements at the east and west terminus of the East-West Sewer line easements, as indicated on Attachment "B ", the loss of crop revenues to Owners, engineering expenses previously incurred by Owners, the nuisance of the sewer line passing through the Property prior to subdivision and the reduction in value of certain private lots within the Property due to the County easements. A further credit of *500.00 shall be allowed against the ILA to each lot owner at the time of hook -up to compensate for the County's not installing side sewer lines connecting the "Ts" to individual lots, as would be the case if the County was installing a ULID sewerage system the amount of this additional credit amount is based upon the average cost of installing a side sewer connection, estimated as approximately 2500.00, from bids received recently). The GFC applicable under County ordinance or resolution at the tine of hook -up of an individual lot shall be the amount payable, less any County participation moneys applicable to reduce said amounts at the time of hook -up. The GFC amount may increase or change from present figures due to periodic adjustments by the County, and the level of applicable participation moneys may also be reduced or change according to County policy. The combined 11200.00 credit allowed future lot owners shall remain constant, as will the ILA amount.

Volume is calculated at 6" depth for "208" trcatmcnt and at 8" depth for storage. as follows: At 6" depth: Pond Volume = (0.5 ft. depth x pond floor arca) + (112 x 0.5 x 2.0 x pond floor perimeter) = 0.5A +0.5P At 8" depth: Pond Volume = (0.67 ft. depth x pond floor arca) + (1/2 x 0.67 x 2.68 x pond floor perimeter) = 0.67A +0.89P POND 1: 1 .4--2 0 feet — 6 "= 0.5rt.

Block 2 of Ridgcmont Estates No. 4 - 4th Addition, Tat ono p 4 at thc southeast corner of 20th Avcnuc and Timberlanc Drive. This pond was sized to take drainage from an area which includcd the south sidc of 20th Avcnuc from Timberlanc to Sonora Street. on thc assumption 20th Avenue would slopc downward to«•ard thc west in this section. As it turns out. a high point is being created in 201h Avcnuc at Station 22 +29.82, roughly halfway between the plat linc and thc centerline of Sonora. Original "Paved Area" of "Basin D" of Ridgcmont Estatcs No. 4 - 4th Addition. including south half of 20th Avcnuc to Sonora Street within Ridgcmont Estates North - 2nd Addition that was originally includcd in sizing "Pond D" = 6.820 sq. R. (see attached data for R.E. No. 4 - 4th Addition. dated March 6, 1992) Actual paved arca draining to "Pond D ": From Original "Basin D" of Ridgcmont Estates No. 4 - 4th Addition = 3,310 sq. ft. of asphalt From street and one driveway in Ridgcmont Estates North - 2nd Addition = 2.710 sq. ft. TOTAL = 6,020 sq. R. Conclusion: Since thc area of asphalt pavement draining to existing "Pond D" is less now than it was originally dcsigncd for. the cxisting pond has sufficicnt capacity for drainagc Basin IA of Ridgcmont Estates North - 2nd Addition. ains to thc existing "208" pond in Lot I, Block 3 of Ridgcmont Estates No. 4 - 5th Addition. f east comer of 20th Avcnuc and Timberlane Drive. This pond was sized to take drainage from an area ( "Basin F ") on thc cast side of Timberlanc Drive north of 20th Avcnuc. including a paved temporary cul-dc-sac. The cul-dc-sac is no longer a part of this drainage area, since a drainage pond was dcsigncd on the cast side of Timberlanc immediately north of thc Ridgcmont Estates No. 4 - 5th Addition plat line (sec Ridgcmont Estates North - 1st Addition). The portion of Ridgcmont Estates North - 2nd Addition that drains into this pond is the north half of 20th Avcnuc from the high point at Station 22 +29.82 to thc west. which is a smaller area than the cul-dc-sac was. Area of cast part of cul-dc-sac = 4.680 sq. fl. (see attached data for "Basin F ", submitted Junc 3, 1992) Arca of 20th Avenue from High point to plat lino = 1,580 sq.ft. Conclusion: Since thc area of pavement that is bcing added to the cxisting pond is &ss than the arca of pavcmcnt that is no longer draining to thc pond the net effect is that thc existing pond has sufficient capacity to acccpt thc drainage from Basin 2A of Ridgcmont Estates North - 2nd Addition.

Spokane County Washington Plans and calculations for this area were originally submitted under the title, "Tupper /Seventh Day ,Adventist Church ", and approved by Spokane County Engineers on June 15, .1993.', Tupper's portion of that original submittal was the area east.of the centerline of Timberlane Drive. This portion is now included in "Ridgemont Estates North 1st Addition ", along with additional street area on 16th and 17th Avenues. Thus, two of 1 the orii nal four street plan - profile sheets have been revised to show the additional street area within the plat, and have been retitled "Ridgentont Estates North 1st Addition " Basically, two main areas are affected on the revised (and retitled) plan sheets • (1) 16th Avenue has been extended eastward from Timberlane Drive to the east plat • boundary, and (2) 17th Avenue has been extended from the end of radius east of Timberlane Drive to the east plat boundary., . The two, drainage basins within Ridgemont Estates North - 1st Addition are the same as those used for Tupper's portion of the original submittal (i.e., the portion east of the Timberlane Drive centerline). The NE Basin is north of 17th Avenue and east of Timberlane Drive, while the SE Basin is south of 17th and east of Timberlane. The natural ground slopes downward to the southeast. For purposes of calculating, we have assume) the front 30' of each lot will be sloped toward Timberlane, and we have included -runoff from assumed houses and .driveways on each lot in the plat in the calculations for • on -site drainage basins. " ' ! • 1 : The additional street area now included in the plat slopes eastward,, off the plat, along both • 16th and 17th Avenues. As noted on the plans, this runoffflowsto an area that is within t he overall preliminary plat of "Ridgemont Estates North ", and will be included in future additions as they are developed, 1 1 \ 1 1 1 1 1 1 1 1 1 1 1 1 1 1 SUMMARY TABLE NO.1: ON -SITE DRAINAGE BASINS L Basin Name: N[: SF, Units Total Area 19,957 39,346 sq.0.

IN GENERAL, for any drainage pond with 4:1 side slopes on all sides, the pond volume can be calculated with two components: the volume dircx:tly above the floor area plus the volume above the side slopes. Volume is ralculattxl at 6" depth for "208" treatnumt and at 8" depth for storage, as follows: At 6" depth: Pond Volume = (0.5 ft. depth x pond floor area) + (1/2 x 0.5 x 2.0 x pond floor perimeter) =0.5 A+0.5 P At 8" depth: Pond Volume = (0.67 R. depth x pond floor area) + (1/2 x 0.67 x 2.68 x pond floor perimeter) = 0.67A +0.89P 2.68 fmt - `6- 2.0fwtH POND NE: ** * ** *t **.* *** *** ♦ * **** fit***** 44 * * ** * * * * *R*0* * ** * * *** *** * * "i *iii * *** *44s4s Pond floor Area, A = 1/2 (8 x 13) + (8 x 20) + (9 x 33) = 52 + 160 + 297 = 509 sq. ft.
