(509) 458-6840 IPF Project No. 98418 , . This report has been prepared by Dean Franz, P.E.; and the staff of Inla.nd Pacific Engineering Company under the direction of the undersigned professional engineer whose seal and signature appear hereon. wns . e , , - 266-35~ o 51tv-~ w~.Ae~ ~Slon,AL"~~~'7. ' EXPIAES Dean Franz, P.E. . 1 GENERAL ' The proposed plat of Carnahan Crest, Phase 2 is a development of 4 duplex residential lots located east of Carnahan Road, south of 17' Ave., and within Spokane County, Washiagton. The proposed plat is located in Sec. 26, Township 25 N.,Range 43 E., W.M. The plat is approximately 1.8 acres, with approx. 0.6 acre for the residential duplex units, the remained is designated for open space. The plat will utilize the road and drainage facilities which were designed for Carnahan Crest, and approved by Spokane County on May 4, 1990. The site will be accessed through the use of private roads, and Grassed Percolation Areas (GPA) for stormwater treatment a.nd disposal. The site consists primarily. of dryland native grasses with some scattered trees. The site generally drains to the northwest, towards Camahan Street. Slopes vary from nearly flat to about 2%. A location map/soils map has been included within the appendix of this document for reference. There are no natural or man-made drainage channels located on-site. The drainage facilities serving both Carnahan Crest and Carnahan Crest Phase 2, are all located within the Carnahan Crest plat. Presently, the approved drainage design for Carnahan Crest provide for GPA. Some of the GPA areas will be modified and enlarged to accommodate the addition of two duplex units. PURPOSE The purpose of this Drainage Report is to present a drainage design approach which is planned to be used in the course of site development. The Drainage Plan is prepared to be in conformance with design standards of the Spokane County C'ruidelines for Stormwater Management. ANALYSIS METHODOLOGY d'c DESIGN Spokane County Guidelines for Stor»rwater Management (GSIv) specify the site analysis for . stormwater pond retention and disposal is to be analyzed using the Bowstring Method. The design , storms are: 10-yr on-site only, and the 50-yr storm event for on-site plus off-site area. The worse- case scenario is to dictate the design. The Bowstring calculations are provided in the Appendix. The analysis demonstrates that two Type `B' standard drywells are needed. A third Type `A' drywell has been added to provide an additional factor of safety. SUBSURFACE SOIL CHARACTERISTICS The Spokane County Soils Survey map (Sht. 74), see Exhibit `B', shows the site consists of preapproved soils Marble Sandy Loam (McB), which is pre-approved for standard drywell discharge, per Spokane County dra.inage sta.ndards C'ruidelines for Stormwater Management (GSM). Spokane County conducted an on-site subsurface investigation in 1989. Three borings were dug on the project site to a depth of approximately 20 ft. The soil logs confirmed the presence of a very granular soil to the depths investigated. See the Appendix for a copy of these soil logs. Inland Pacif~cc Engineering Co. Page 1 Carnahan Crest Phuse 2: Drainage Report OFF-SITE DRAINAGE ' A.a area to the south and east, located off-site, contribute surface runoffonto the project site. Runoff flows onto the site by sheet flow. The contributing off-site area is 1.66 acres. DRAINAGE MAINTENANCE The present plat of Carnahan Crest has ma.intenance responsibilities of the drainage facilities designated to the CARNAHAN CREST OWNERS ASSOCIATION, in a Covenant recorded on July 10, 1990, per Auditors # 9007100278. The same homeowners assoc. will be responsible for maintainiag the dra.inage facilities. A drainage easement will be granted to Carnahan Crest Phase - 2 property for the use of the drainage system. Drainage Summary Storm Ponds for Basin A(qer Basin Map) . The plat of Camahan Crest Phase 2 will have access from the private roads in Camahan Crest, first phase. Therefore, a portion of the drainage facilities in the first phase are to be modified. The modifications are limited to the drainage basin which will be impacted by the second phase, which is Basin A.

Inland Pacific Engineering - 707 W. 7th Avenue, Suite 200 Spokane, WA 99204 Re: Road & Drainage Comments 1 for Carnahan Crest, Phase 2 PE-1758 . Dean, ` The County Engineers have performed a cursory review of the road and drainage plans for this project. The drainage plan and calculations, as submitted, appear -to meet the standards as they are set forth in the C'ruidelines for Stormwater Management, with one exception. This is discussed below. The road plans previously approved by the County for Phase 1 are not acceptable. As you are aware, these plans were approved by the County on May 4, 1990. Section 2.02, Paragraph A, Clause 3 of the 1981 Spokane County Road Standards states that plan approvals are effective for two years; therefore, these plans expired on May 4, 1992, over six years ago. . Because Carnahan Crest Phase 2 requires access through Carnahan Crest Phase 1 via roadways that are not constructed and do not have approved plans on file with the County, the County Engineers must require the resubmittal of the road and drainage plans for these roads. Specifically, the. roads in question are 17`hLane and Viewcrest Lane. fllso, Section 2.021 Paragraph A, Clause 3 of the 1981 Spokane County Road Standards states that expired plans shall be revised to reflect current standards. As such, the plans that are resubmitted must conform to the 1995 Spokane County Road and Sewer Stcnrdacrds for Construction, as amended. With this in mind, it appears that there are at least three deficiencies in the expired plan. First, adequate turnarounds have not been provided at the termini of Viewcrest Lane. Second, the intersection return radii at 17" Lane and Viewcrest Lane do not meet the current 30' standard. Third, an erosion and sediment control plan must be submitted to 1026 W. Broadway Ave. 0 Spoicane, W:\ 99260-0170 •(509) 456-3600 FAX: (509) 324-3478 TDD: (509) 324-3166 ~ the County, in conformance with the Addendum to Section 4.5 of the Guidelines for Stormwater Management. Along with the revised plan, financial sureties for the construction and inspection of the roads must be submitted to the County. The amounts of these sureties will be calculated by the County when revised plans are received. This is not meant to be a comprehensive list of items that may need to be added to or revised on the plans. As you know, it is the responsibility of the Design Engineer to ensure that the plans that he/she is submitting conform to the current County standards. Please highlight all changes to the plan in color. You may submit the revised plans at your earliest convenience. Sincerely, Spokane County Engineers / Doug Busko, P.E.

Residential net densities in the Urban category should range between 1 and 17 units per acres. The proposed density of 2.1 units per acre is in accord with the density range suggested by the Urban category. 2. Arterial Road Plan: The proposal has direct access to 17th Lane and Viewcrest Lane which are designed as private roa.ds and are not designated arterials on the Arterial Road Plan. The nearest arterial is Carnahan Road which is located approxi.mately 300 feet west of the proposal, The Arterial Road Plan designates Carnahan Road as a Minor Arterial with a recommended right-of-way width of 80 feet. 3.. County Parks Plan: The Spokane County Parks and Recreation Plan identifies Dishman Hills Natural Area and Edgecliff Park as the nearest park facilities. : Edgecliff Park is designated as a Neighborhood Park and is located approximately 2 miles southeast of the proposal at Eighth Avenue and Park Road. The Dishman Hills Natural Area is designated as a Conservation Area and is located approximately 3 miles southeast of the proposal,,just south of Sprague Avenue and Sargent Road. (See Item S). C. Site Characteristics: The site is presently undeveloped, vacant and reladvely flat. Evergreen trees, natural ground cover, and rock outcroppings are located throughout the site. D. Neighborhood Characteristics: The surrounding area is developed with single family residences to the north, east and wesL Most of the area to the south consists of large acreage tracts, some with single family residences. E . Zoning Analysis: Prior to the implementation of the Spokane County Zoning Code on January 1, 1991, the site and surrounding area was zoned Agricultural Suburban (AS) under the, now expired, Spokane County Zoning Ordinance. Most of the area which has been developed, was developed consistent with the density and development standards under the Zoning Ord.inance. There has not been any recent zone reclassification'requests in the surrounding area.

A Homeowner's Association will be created to own and maintain the common open space. As designed, the common open space serves as buffer between the existing residential developments located to the north and east of the proposal. I. Density: The net density is approximately 2.1 units per acre which is consistent with the Urban Residential-3.5 (UR-3.5) zone and the density guidelines suggested by the Urban category of the Comprehensive Plan. J. Drainage: A drainage plan is required.

The Planning Deparanent has detennined that "No probable significant adverse impacts" wofild result from the proposal being developed and has issued a Determination of Nonsignificance ("DNS"). I The "DNS" was circulated to 14 other agencies of jurisdiction and other agencies/deparnnents affected by the future development for review and comment. The "DNS" comment period ends November 15, 1994 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 norice on a sign posted on the proposal site. The Hearing Examiner may consider additional environmental related testimony at the public hearing. IV.

All air pollution regulations must be met. 2. Air pollution regulations require that dust emissions during demolition, constnuction and excavarion projects be controlled. This may require use of water sprays, tarps, sprinklers or suspension of activity during certain weather conditions. Haul roads should be treated, and emissions from the transfer of earthen material must be controlled, as well as' emissions from all other construction-related activities. 3. SCAPCA smongly recommends that all traveled surfaces (ingress, egress, parlQng areas, access roads) be paved and kept clean to minimize dust emissions. 4. Measures must be taken to avoid the degosition of dirt and mud from unpaved surfaces onto paved surfaces. If tracking or spills occur on paved surfaces, measures must be taken immediately to clean these surfaces. 5. Debris generated as a result of this project must be disposed of by means other than burning (i.e., construction waste, etc.) 6. All solid fuel burning devices (wood stoves, pellet stoves, etc...) must comply with local, state, and federal rules and regulations. SPOKANE COUNTY DIVISION OF BUILDINGS ; 1.

DESCRIPTION OF WORK Inspection by STI Northwest personnel or other agency personnel shall not relieve the contractor of his responsibility to construct the facilities covered by this agreement to the line and grade shown on the approved plans or as staked by the engineer. This contract agreement does not include construction management, scheduling activities, or preparation of irrigation "Record Drawings" as required by Spokane County for final acceptance of the street and drainage plans. 1. The scope of these construction engineering services includes: A) Periodic observation and reporting of specific construction activities on this project which include; Subgrade, Bases, Pavement, Storm Drainage, and Material Testing; B) Maintenance of all construction records related to construction activities outlined in paragraph "A" above, which may include; daily inspection reports, manufacturers' certifications, material test reports, and correspondence; C) Assurance that the construction of the roads is according to the approved plans accepted by the Spokane County Engineer, Spokane County General Provisions, the Standard Specifications, and applicable portions of the WSDOT Construction Manual; D) Development of Post Construction Record Drawings for Street and Storm Drainage Facilities; it is understood the facilities inspected by firms other than STI Northwest will be certified by those firms in a form acceptable to Spokane County; E) Coordination of the testing of construction materials for compliance to the plans accepted by the Spokane County Engineer, Spokane County General Provisions, the Standard Specifications, and applicable portions of the WSDOT Construction Manual. 2. Prior to acceptance of the roads and drainage facilities by Spokane County, the Engineer shall submit all construction records and the Record Drawing to the Spokane County Engineer. 3. The effort to complete inspection and certifications in accordance with Spokane County requirements varies widely and is closely related to how well your contractor plans his activities, communicates with our inspection staff, and the quality of his work. A pre- construction meeting with the contractor, project sponsor, and STI staff is strongly recommended prior to commencement of any construction activity. This meeting will be held to determine the schedule, client contact, owners representative, and payment responsibility for re-inspection charges for incomplete or inadequate work. Inspection page 3 STI Northwest will provide as much soil and materials testing in house as possible, but will not hesitate to use outside consultants where their specialty is required. We feel we can provide better service in quality control, and streamline the inspection process as required by Spokane County. The soil and material testing is billed on a time and expense basis. A monthly invoice will be prepared and sent to you for the inspection and materials testing. The amount of testing is impossible to anticipate, and will require your contractor and construction manager to coordinate with our inspection department. The services described herein will be performed as needed and billed on the basis of time and expense as outlined in the maximum hourly billing rates by job classification included in the Work Authorization. We estimate the cost of inspection services as outlined above to be approximately $1,425.00. We also estimate the cost of soil and material testing to be approximately $965.00. Ted Clark agrees to provide certifications to STI, or arrange for appropriate certifications from other firms. Ted Clark shall also include provisions in their construction contracts to back charge their contractor for the cost of STI services which may be required for re-inspection or re-testing of facilities which failed to meet the required standards. Billings for said re-inspections will be carefully identified on STI's billing to Ted Clark. Ted Clark will be responsible to back charge their contractor. It is also understood that no work shall commence within any portion of the proposed Spokane County Right of Way without first obtaining a written permit and approved plans from the County Engineer. It is also understood that any project facilities constructed without adequate inspection and documentation by STI Northwest will be removed and rec4nstructed in accordance with approved project plans and Spokane County Specifications, or STI will not be responsible for project certification or submission of record drawings to the County Engineer.
