A previous draft of an Easement Agreement was recorded under Spokane County Auditor No. 9409200309. 3. Renz and the County desire to terminate the Easements referred to in paragraphs 1 and 2 above and concurrently substitute and replace them with this Agreement.

Notwithstanding the provisions of paragraph 2 above, it is specially understood and agreed that the drainage easement may receive the natural flow of water from undeveloped area within the drainage basin for this easement identified in that certain study performed by Simpson Engineers, Inc. in conjunction with Project Nos. P -1684B and P -1684C on file with the Spokane County Engineer. With the consent of Spokane County or at its request, the description of the Developed Property may be expanded to include newly platted or divided properties ( "additional •properties") if (a) the developer of such additional properties has entered into a written agreement with the entity responsible for operation, maintenance and repair of the drainage facilities pursuant to this agreement, (b) said agreement addresses payment of a pro rata share of the costs of operation, maintaining and repairing the facilities by the owner of such properties, in accordance with paragraph 5 below (c) said agreement has been approved as to form by the County and is fully executed and recorded before final plat approval, and (d) thirty days written notice has been provided by Spokane County to the owners of the property described in Exhibit "A" and to the entity responsible for operation and maintenance of the drainage facilities that such additional properties are being added to the Developed Property. 4.

It is specifically understood and agreed, however, that in the event additional properties are added to the description of the Developed Property, the owners of said additional properties shall be required to reimburse the Homeowners Association for the cost of operation, maintenance and repair of said facilities on a pro rata basis. The pro rata annual reimbursement costs for such additional properties shall be determined as follows: Spokane County may, at its option and at any time hereafter, assume responsibility for operation, maintenance and repair of the drainage facilities and may levy service charges on _lots within Ridgemont Estates North 3rd and 4th Additions, and on any additional properties added to the Developed Property, for the pro rata share costs of such operation, determined as follows: SRS /9409 -011 Pro rata share = annual maintenance cost x F. F = number of lots added to the Developed Property divided by (number of lots added to Developed Property + number of lots in Ridgemont Estates North 3rd and 4th Addition). -3- SRS /9409 -011 Pro rata share for each lot = annual maintenance cost divided by (number of lots added to Developed Property + number of lots in Ridgemont Estates North 3rd and 4th Addition).

It is specifically understood and agreed that lots or owners of lots in Ridgemont Estates, Ridgemont Estates No. 2 and Ridgemont Estates No. 3, although included in the definition of "Developed Property ", are not liable for reimbursement of costs or for service charges levied for maintenance, operation and repair of the drainage facilities as provided for in this agreement. This limitation shall not be construed to otherwise limit the statutory authority of Spokane County to levy rates, charges or assessments on such lots or the other Developed Property if the owners of such property receive or will receive services or benefits from additional storm water control facilities installed by the County or from additional storm water services provided by the County. 8. If the Homeowners Association fails to maintain and operate the drainage facilities in good working order, Spokane County may give written notice of such failure to the Homeowners Association and if such failure is not corrected within the period indicated in said notice, Spokane County shall have the right to correct said maintenance failure or compel such failure to be corrected at the expense of the Homeowners Association. -4- 9.

Hormann, P.E., County Engineer The off-site regional retention pond, located just south of the intersection of 16th Ave & Shamrock Rd. will continue to receive stormwater from the "Ridgemont" area, which also includes Ridgemont Estates North 3rd & 4th Add. Therefore, the maintenance responsiblities of this pond need to be formalized as part of the final plat. The easement documents applicable to the off -site regional retention pond are currently under review within the County. As a brief summary of the overall requirements regarding the off -site pond, the existing easement will need to be replaced with a new drainage easement which will encompass a slightly different area, and will have easement language clearly defining maintenance responsibilities. The off -site regional retention pond is to be maintained by a homeowner's association which needs to be formed as a joint association within Ridgemont Estates North 3rd & 4th Addition. As was stated in my letter dated June 20, 1994, this association needs to be formed before the plat can be finalized. Please provide me a copy of the final association documents as soon as the formation is complete. Sincerely, Spokane County Engineers Dean Franz, P.E.

Maintenance of Retention Ponds Spokane County No.'s P- 1684B, P -1684C Dear Dave: C O U N T Y A DIVISION OF THE PUBLIC WORKS DEPARTMENT The issue of maintenance responsibility of the two retention ponds, associated with these projects, needs to be ascertained. The first pond presently functions as a regional retention pond for the Ridgmont area. It is located in a natural tow area, within an open pasture, south and adjacent to the intersection of 16th Ave and Shamrock Street. It is encompassed by a drainage easement dedicated to Spokane County (Auditor's File #8004140245). The easement specifies that the County is not responsible for maintaining the pond; rather the pond is to be privately maintained. The proposed development will encroach upon this easement with a public street and single - family lots; therefore the design engineer has been asked to determine the 100 -yr stormwater elevation and stormwater limits within the pond area. It is planned to revise the limits of the pond and place it within a separate tract. The second pond is planned to be constructed as part of Ridgemont Estates North 3rd & 4th Add. It will be Located within the 3rd Addition, contained within a tract. There is no stormwater maintenance agreement in place for the Ridgemont area. Normally the County will consider assuming maintenance responsibility only when a maintenance agreement is made between the property owners and the County. The agreement states that the County will collect fees from the property owners, and in return the County will inspect and maintain the ponds. Therefore, these ponds will likely need to be privately operated and maintained.

Letter to Dave Renz 22 Anril 1994 Page 2 Because pond maintenance will become more critical with homes nearby, you need to develop a maintenance plan. We need a proposal from you regarding the maintenance organization and plan. This issue will need to be resolved soon. We need to agree on a proposal before the road and storm plans can be approved, and the maintenance details will need to be worked out before final plat approval.

Owners are willing to grant to the County perpetual easements, free of encumbrances and with appropriate access, running through the Property in an alignment acceptable to the County, in considera- tion of the County paying all costs 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 ( "GFC "), monthly service charges, and an In Lieu of Assessment charge (ILA), as specified herein, upon connection of the Property, or future lots therein, to the Facilities. It is the Intent of this Agreement to reduce to writing the Parties' agreement with respect to the conveyance of easements 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 12" sanitary sewer pipe, and necessary 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 co install side sewer connection lines from the "Ts" to individual lots, which shall be She Owners' responsibility to install. All manholes installed within the Facilities shall be designed and constructed to include a one foot (1') 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. Owners agree to grant to the County perpetual easements in the property, free of any encumbrances, along with temporary access easements thereto, all as specifically indicated on Attachment "3 ", 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 eascmenc(s), temporary construction easement permits, access easements, or any other documents required of Owners under the terms of this Agreement. Section 7: USE OF CONSTRUCTED SU3DIVTSION 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 lbt at the time of hook -up to the County's general sewerage system shall pay the County's General Facilities 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 $770.00 for residential properties, currently reduced by a forty percent (401) 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 - I 'tE 994 r•.CE 1135 Under this Agreement, the ILA payable at the time of hook -up shall be permanently fixed at $1,500.00 (tne special benefit for residential parcels within a ULID is currently $2,500.00, which amount is currently reduced by a forty percent (401) County subsidy, leaving a balance of $1,500.00 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 Ease —West Sever line easements, as indicated on Attachment "3 ", 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 $500.00, from bids received recently). The GFC applicable under County ordinance or resolution at the time of hook -up of an individual lot shall be the amount payable, less any County participation moneys applicable to reduce said amounts at tne 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 $1200.00 credit allowed future lot owners shall remain constant, as will the ILA amount. The Parties 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 either 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 co writing and executed with the same formalities as this present Agreement.

No waiver of any breacn of this Agreement shall be held to be a waiver of any other or subsequent breach.

Review No. 4 Spokane County No. P -16840 Dear Doug: A review of the road and drainage plans and calculations for this project has been accomplished. The plan labeled "Drainage Easement Topography" (Sheet 3) needs to be signed and dated by the Developer. Once this is accomplished, the plans can be approved for construction. You can pick up the original plan mylars at the Public Works Building. Please call before you come, so we can have them readily available for you. Sincerely, Spokane County Engineers Dean Franz, P.E.

Spokane, WA 99212 Subject: Ridgemont Estates North No. 3 & 4 Review #3B: Offsite Pond Spokane County No. P- 1684B, C • Provide a legal description of the proposed easement. C 0 U N T Y A DIVISION OF THE PUBLIC WORKS DEPARTMENT Ronald C. Hormann, P.E., County Engineer Dennis M. Scott, P.E., Director A review of the drainage plans and calculations for this project has been accomplished. The calculations have been reviewed and were found to be in order, complete and correct. Because construction work is necessary to complete the pond, the retention pond plans, which were submitted, need to be included in the Ridgemont Estates North No. 4 road and storm plans. Please change the page numbering system and incorporate the pond plan into the engineering plan set. It was decided in a meeting we held with Dave Renz and Mike Phillips on July 20, 1994, to place the regional pond within an easement: The existing easement is no longer adequate because the affected area is no longer correct (due to proposed plat changes), the responsibility for maintenance is no longer applicable, and some of the easement language needs to be revised. The new easement will need to encompass the entire pond, which includes the area that will be impacted by stormwater storage, for the 100 -yr, 24 hr storm event. The easement also needs to include the 15' wide maintenance access drive connecting from 16th Ave. In order for the County to proceed with the preparation of a new drainage easement, the following information is needed from your office: • Clearly show the limits of the proposed easement on the retention pond plan. 1026 W. Broadway Ave. Spokane, WA 99260 -0170 • (509) 456 -3600 FAX: (509) 324 -3478 TDD: (509) 324 -3166 2 " Offsite Regional Retention Pond (P- 1684B, C) Review No. 3B page 2 • Provide a title report showing proof of ownership of the properties which will be encumbered by the new easement. Included in this, needs to be the list of names and titles (where applicable) of individual(s) who will need to sign the easement document. • The name of the developer who will be responsible for construction work within the easement. And the name of the developer's authorized agent who will be signing the document. • Provide an exhibit of the proposed easement limits in relation to the surrounding properties. Provide on 8 1/2" x 11" or legal size paper. This along with the legal description will be referenced in the new easement documents. The responsibility of maintaining the pond will be with the homeowner's association, which is being formed for Ridgemont Estates North No. 3 & 4 Addition. The maintenance requirements will be specified in the final plat documents, or a separate covenant referenced in the final plat language.

Address all comments by revising the plans and drainage calculations, unless otherwise noted. This pond functions as a regional retention facility. It is located within natural low -area in an open field; and is south and adjacent to the intersection of 16th Ave and Shamrock Rd. The pond is presently within a drainage easement, recorded under Auditor's File No. 8004140245. X Place the pond within a tract and include it in the final plat documents to Ridgemont Estates North 3rd Add. The tract is to encompass the area defined by the 100 -yr max. water surface elevation, plus a 20' wide access point from a public roadway. The tract is to be dedicated to the homeowner's association, who will , �Al, be responsible for maintaining the retention pond. #J1# Ist f4x4 e 7 /A4/9-1" SALAU*v, The plan shows a portion of the flood area (resulting from a 100 - yr s torm) within a future lot. As stated above, the flood area is to be encompassed by a tract and will not be permitted to encroach within a lot. 1/3) Grading Plan: Horizontally define the grading requirements. This is normally done by station /offset call -outs of key points at the bottom of the pond, or by coordinates, and by defining the pond side slope. In this case, it may be more practical to horizontally define key points along each contour line. +'b: The plan indicates a low rise in the easterly portion of the pond, which will be located 1.0' above the bottom of pond. According to the drainage calculations, the bottom of the pond will be a flat, level surface. Address discrepancy. If the intent is to have a flat level bottom set at 2018.0, then state it in the grading plan. 4) / Gravel Maintenance Drive a: Provide a typical cross section of the maintenance drive, showing gravel width, gravel thickness and material.

V' Provide bollards at the gravel drive entry, next to the road. Provide 2 fixed outer bollards, and 2 removable inner bollards. Provide and reference a bollard detail. 4' The gravel entry is to have a minimum of a 30' radius at the returns, in the intersection with the paved public road. Show the gravel returns, define the radius size, and show the edge of pavement in the plan. 5) The road pavement is to be set at a minimum of 1.0' above the P/ maximum water level achieved during the 100 -yr storm event. See comments to the drainage calculations, listed below. Storm Drainage Calculations These calculations are labeled "Part II Off -Site Drainage Analysis." D1) The calculations use a precipitation of 2.6" for the 100 -yr, 24 hr storm event. While this amount is common through much of Spokane County, it is not this constant value everywhere. According to the isopluvial map on record at the County, and provided in the Precipitation - Frequency Atlas published by NOAA, the precipitation amount is 3.0 ". Revise the calculations using the // higher precipitation value. t' D2) Basin Offsite 1: Vc: The area listed as "undeveloped hilltop to south" needs to be analyzed as being developed. This could be developed in the future, which is also indicated in the basin map. This increases the impervious area by 105,960 s.f. (i.e. 20% impervious). 'A The regional retention pond area, within the flood area, will generate a CN = 100, and will cover approximately 2.4 acres. The remaining area around the pond will have a CN = 61, as used in the calculations. V c: The two changes listed above, will change the CN from 67.0 to 68.0. Revise the calculations for Offsite-1. Basin Offsite 2: The calculations list the total area for this basin equal to 6.80 acres. However, upon checking the area referencing the basin map, the area is 8.30 acres. Revise basin area in the calculations. A CN of 70, as listed, is correct.

Hormann, P.E., County Engineer Dennis M. Scott, P.E., Director August 4, 1994 Doug Christenson Simpson Engineers, Inc. N. 909 Argonne Rd. Spokane, WA 99212 Subject: Ridgemont Estates North No. 3 & 4 Review #3B: Offsite Pond Spokane County No. P- 1684B, C Dear Doug: C O U N T A DIVISION OF THE PUBLIC WORKS DEPARTMENT A review of the drainage plans and calculations for this project has been accomplished. The calculations have been reviewed and were found to be in order, complete and correct. Because construction work is necessary to complete the pond, the retention pond plans, which were submitted, need to be included in the Ridgemont Estates North No. 4 road and storm plans. Please change the page numbering system and incorporate the pond plan into the engineering plan set. It was decided in a meeting we held with Dave Renz and Mike Phillips on July 20, 1994, to place the regional pond within an easement. The existing easement is no longer adequate because the affected area is no longer correct (due to proposed plat changes), the responsibility for maintenance is no longer applicable, and some of the easement language needs to be revised. The new easement will need to encompass the entire pond, which includes the area that will be impacted by stormwater storage, for the 100 -yr, 24 hr storm event. The easement also needs to include the 15' wide maintenance access drive connecting from 16th Ave. In order for the County to proceed with the preparation of a new drainage easement, the following information is needed from your office: • Clearly show the limits of the proposed easement on the retention pond plan. • Provide a legal description of the proposed easement. 1026 W. Broadway Ave. • Spokane, WA 99260 -0170 • (509) 456 -3600 FAX: (509) 324 -3478 TDD: (509) 324 -3166 Offsite Regional Retention Pond (P- 1684B, C) Review No. 3B page 2 • Provide a title report showing proof of ownership of the properties which will be encumbered by the new easement. Included in this, needs to be the list of names and titles (where applicable) of individual(s) who will need to sign the easement document. • The name of the developer who will be responsible for construction work within the easement. And the name of the developer's authorized agent who will be signing the document. • Provide an exhibit of the proposed easement limits in relation to the surrounding properties. Provide on 8 1/2" x 11" or legal size paper. This along with the legal description will be referenced in the new easement documents. The responsibility of maintaining the pond will be with the homeowner's association, which is being formed for Ridgemont Estates North No. 3 & 4 Addition. The maintenance requirements will be specified in the final plat documents, or a separate covenant referenced in the final plat language. Your office will be provided a draft copy of these maintenance and drainage covenants, along with drainage language normally associated with plats, for coordination and final recording.

At the west end of this plat, stormwater from Ridgemont Estates North - 2nd Addition flows eastward into this plat to the low point at Station 2 +06.99, and enters Ponds 4A and 4B The basin data above includes the triangle of area, including asphalt, that lies within R E North - 2nd Addition and flows to Pond 4B. The data for Basin 4A does not include any asphalt within 2nd Addition, because that asphalt is already included for "208" treatment in the existing "Pond 4" in 2nd Addition. The only stormwater from 2nd Addition that reaches Pond 4A is 0.35 cfs excess carryover past the 10 LF curb drop to "Pond 4 ". See the Drainage Report, street plan - profiles, and drainage plan map for Ridgemont Estates North - 2nd Addition. Basins 4A and 4D include land area outside of Ridgemont Estates North - 4th Addition that drains into these' basins from the north. That land is considered in its future developed condition, as per the Preliminary Plat of Ridgemont Estates North (Note: R. E. North - 8th & 9th Additions are the proposed plats to be located immediately to the north of Basins 4A and 4D; they will likely be platted within a year of the current 4th Addition). The anticipated roofs and yards of those future lots are included in Basins 4A and 4D; 3 future roofs/yards drain to Pond 4A, and 6 future roofs/yards drain to Pond 41). The future street(s) and front 30' of each future lot (including driveways) will be included in future drainage facilities. Basin 4C includes about 8,700 sq. ft. of gravel at the lift station site (Utility Lot A), and 3 Tots in Ridgemont Estates North - 3rd Addition (Lots 10 -12, Block I). This basin drains to "Drainage 'Pond 3A ", which.occupies "Utility Lot'`B'" within the northern boundary of R.E. North - 3rd 'Addition. See Part 1 of the 3rd Addtion drainage report and accompanying maps. Basin 4E drains off -site to the large drainage area to the east, along with runoff from Basin 3E of Ridgemont Estates North - 3rd Addition, from the (hillside to the SE of these plats, and from the undeveloped farmland to the northeast of R.E. North - 4th Addition (within the preliminary plat of Ridgemont Estates North). See separate analysis of the large easement area in Part II of the drainage report for Ridgemont Estates North - 3rd Addition. IN GENERAL, fonaiiy drainage pond with 4:1 side slopes on all sides, the pond volume can be calculated with two components: the volume directly above the floor area plus the volume above the side slopes. Only three parameters need be known: ponding depth, floor area and perimeter. Volume is calculated at 6" depth for "208" treatment 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) = 0.5A +0.5P At 8" depth: Pond Volume = (0.67 ft. depth x pond floor area) + (1/2 x 0.67 x 2.68 x pond floor perimeter) = 0.67A + 0.89P POND 4A: 6 " =0.5ft. ********* * * *** * * * * * * * * * * * ** * * * * * * * * * * * ** iii****** * * ** ** * * * * * * * * * * * * * * * * * * * * ♦ * * ** Pond Floor Area, A = 17 x 40 = 680 sq. ft.

Specifically, representative values for soil percolation rates and soil- subgrade "R" values are necessary to evaluate the proposed pavement section and storm drainage disposal system. I The Spokane County Materials Laboratory has reviewed the proposed development plan; made a preliminary investigation of the on -site conditions; and has determined a minimum number of Z percolation rate tests and / stabilometer "R" value tests are I required. It estimates the cost of.such soil borings and tests to be approximately $ /Sao excluding utility location. Additional M terials Laboratory remarks are as follows: 'Vcc c/ 1) p " - /(c S ly ,/ Rg+ C. 7,e, 1 1 ' The Spokane County Materials Laboratory is available to supply this information during the design review process. This information. also may be supplied by any qualified soils firm. The tests and methods must meet Spokane County standards, and be inspected by Spokane County personnel. Please note that the above is a preliminary estimate only; additional tests may be necessary dependent 1 on the conditions encountered, and therefore, actual fees may vary. Actual fees will be based on hourly equipment 'usage rates and salary costs incurred by Spokane County during the progress of the work ' plus a 10 percent administration surcharge. Fees will be invoiced monthly as accrued. Please be advised that signature of this letter constitutes agreement to pay for the above described fees. 1 Failure to pay these fees may result in Delay in completion of approval of the project or other possible sanctions. 1 If you desire to have us undertake this work, please sign below, and return the original to our office.
