Town EngineerqltAf Date: June 19,2008 Re: Resolution 08-22 - A Resolution Approving an Extension for One-Year of the Preliminary Subdivision Plan Approval for the Village (at Avon) Filing No. 4 Summary:.: Resolution 08-22, attached as Exhibit A, is in response to the request by the Village (at Avon) for'. an, extension of the Preliminary Subdivision plan approval and Subdivision Variance approval for the Village-(at Avon) Filing 4.'. The Preliminary Subdivision Plan and the associated Subdivision .Variance are' set to expire two years after approval date, June 27, 2006, unless the applicant requests an extension sixty (60) days before the expiration date, June 27, 2008, showing good`cause..The applicant, -Traer Creek RP LLC, submitted a request for a two-year eidfension of the Preliminary-Subdivision Plan, along with an additional letter that includes a description of good cause for the extension. The extension request is in conformance with requirements of . Avon Municipal Code (AMC) 16.20.110. Staff recommends approval•'of Resolution 08-22, Series_ of 2008, conditionally approving the extension request for a period of one year. Previous Council Action: Town Council approved Resolution 06-14 approving the Preliminary Subdivision Plan and' Resolution 06-13 approving the Subdivision Variance for Village (at Avon) Filing 4, on June 27, 2006. The resolutions are attached as Exhibit B and Exhibit C, respectively. " • Background: Town Council approved the Village (at Avon)" Filing 4' Preliminary Subdivision Plan and associated Subdivision Variance on June 27, 2006. The proposed subdivision is located north of the Swift Gulch Road and Post Boulevard roundabout and includes reconstructed, wetlands, a water tank, and an access road to the water tank. The associated' Subdivision`Vadance increases the maximum road grade from 8.5 percent, as stipulated in the Annexation and Development Agreement for portions of Traer Creek Run north of Interstate 70, to 9.5 percent: Per. Section 16.20:100 of the AMC, the Preliminary Subdivision Plan expires after two years of the approval date. Section 16.20.110 of the AMC states that an extension may be granted for good cause when such request is-submitted by the subdivider in writing to the Town Cleric at least 60 days prior t6the date of approval expiration. On January 15, 2008, the applicant's engineer, Kent Kriehn of Alpine Engineering, submitted the response to the Town's October 20, 2006 comments regarding the Final Plat, -Draft Subdivision Improvements Agreement (SIA) and construction drawings. The Town responded to the submittal on February 15, 2008. In the response, attached as Exhibit D; the Town provided' comments regarding the proposed SIA,', construction drawings, and reminded the applicant of the June 27, 2008 Preliminary Subdivision Plan expiration date. On April 16, 2008, Munsey Ayers, the applicant's representative, submitted the request for a two- year extension of the Preliminary Subdivision Plan, attached as Exhibit E;': but the request did not include a description of good cause as required in AMC 16.20.110. The Town's response, dated April 30, 2008 and attached as Exhibit F, requested the applicant to submit the description of good cause. On June 18, 2008, the Town received a letter from Munsey Ayers, attached as Exhibit G, which included the applicant's description of good cause. 0 Page f• Discussion: Staff is of the opinion that a one-year extension should be granted.to the applicant since ,there is no exposure to the Town because no additional development -beyond the Eagle County Health Services District ambulance facility can occur in the Village (at Avon) until the water tank is constructed. Staff is.recommending a one-year extension instead of'a two=year extension in the event that the Preliminary Subdivision Plan needs to be modified a- s`-a result 'of unforeseen changes to the Village (at Avon) development plan. Thisl is a minimal' burden for ,the applicant because all that is required to apply for. another one-year extension is a formal" written request showing good cause. On March 25, 2008, Staff received..a copy, of a JUT 2001 Cultural Resource: Inventory . Report (Report ) that was prepared by Metcalf Archeological Consultants of ;Eagle, , Colorado. The Report identified 9 sites ;within .the.:Village (at Avon). Of these sites, two may,., be. eligible for the National Register of Historic Places since they hold some data potential. One of the sites along Nottingham Gulch (identified as 5EA1736 in. the report) may be.iocated.within,the-area to be. disturbed for the construction of the Filing 4 improvements. The -Report states that data :recovery of, the: site -is a feasible option since it is not located were in-situ; preservation is the best option.,' Staff recommends, as a condition of Resolution 08-22, that. the applicant identifies the location of the.aite to determine if it is. located within. the area.to be disturbed for the construction of'the .Filing 4 .improvements. If the site is located in the area to ..be disturbed, a data recovery effort must b6,'* undertaken to the satisfaction. of the Town before -construction for Filing 4 can start. It should be noted that the June 18, 2008, letter from,Munsey Ayers. (Exhibit-G)' attempts to, connect the request for the Preliminary Subdivision. Plan, extension to.a dispute with the Town regarding the collateralization of the improvements, and the SIA before the Final Plat can be recorded per Section 16.24.100 of the AMC.;; Staff feels that this is a separate issue and is not relevant to the approval • recommendation for Resolution 08-22. Financial Implications: No-financial implications to the Town of Avon .Recommendation: Staff is recommending that the Village (at Avon) Filing 4 preliminary.subdivision plan be granted for one .year,- and a :condition. be added that requires that the developer. conduct an analysis • of the; impacts.of the Filing. 4 construction on.the sites identified in the :July 2001 Cultural Resource. Inventory Report prepared by Metcalf -Archeological Consultants; if :the Filing 4 construction impacts any of the sites than the developer shall undertake- a .'data recovery of the prehistoric site before Filing 4 construction starts.

Set forth below is an outline of the remaining items that need to be resolved before the Final Plat can be scheduled for Town Council consideration. The remaining issues with the construction plans could be a condition of the approval of the Final Plat, though we would prefer to resolve them as soon as, possible. The issues with the Subdivision Improvements Agreement (SIA), however, must be satisfactorily addressed before the Final Plat can be scheduled for Town Council consideration. Subdivision Improvements Agreement: 1. For several reasons, including those described in paragraphs 2 and 3. below, the form of Subdivision Improvement Agreement you submitted is not acceptable. The standard Town of Avon SIA template must be used. I have attached a copy of it and will email you the computer file. Any deviations . from the template which you deem necessary because of a unique aspect of the project must be indicated by underline and strike-through. The draft SIA you submitted states that the proposed improvements are not funded and that no collateral will be posted at this time. Per Section 16.24. 100 of the Avon Municipal Code, the Final Plat cannot be recorded until the SIA is executed and sufficient collateral is provided. The Subdivider's proposal for the Town of Avon Engineering Department to approve the Progress Pay Requests has proven unsatisfactory because it does not provide for adequate collateral and because the associated test reports and letters of acceptance from the utility providers are not received by the time the Progress Pay Requests must be processed. Therefore; the Subdivider must provide collateral in a form that conforms to the requirements in Section 16.24.100 of the Town of Avon Municipal Code. 0 4. The draft SIA proposes breaking the project up into two phases, with the wetlands and associated improvements in the first phase and the water tank in the second phase. Staff supports phasing the project, with the wetlands and associated improvements in the first phase. If the Subdivider would like to split the improvements into two different SIAs, that would be acceptable to staff. That way, the Subdivider could provide collateral now for the first phase and postpone providing collateral for the second phase which is proposed to be constructed several years later. Please be aware, however, per Section 16.24. 100 (1) the plat would not be recorded until after the installation and acceptance of all of the improvements or when collateral is in place for the remaining improvements. 5. Per Section 16.20. 100 of the Avon Municipal Code, the Preliminary Plan will expire on June 27, 2008, two years after it was approved. The approval may be extended for good cause shown, but the request must be submitted to the Town Clerk 60 days before the approval expiration. Based on information provided to me and the time involved in making the latest revisions, it appears that the SIA and Final Plat may not be executed and approved by Council before the Preliminary Plan expires. Therefore, I recommend that the Subdivider apply for a two year extension. Construction Plans: 6. Updated approval letters from the following organizations must be provided: a. Army Corps of Engineers. b. Eagle River Water and Sanitation District. c. The Village (at Avon) Master Design Review Association. 7. Staff recommends relocating the 100' Electric Easement to the actual location of the power lines. 8. The dates on the Final Plat must be updated to reflect that it is 2008. 9. The utility plans do not include sanitary sewer. This indicates that future construction will require demolition and reconstruction of the road to install sanitary sewer. Staff recommends installation of sanitary sewer during construction of the proposed road. 10. The HP Geotech letter, dated March 22, 2005, indicates the 1.75:1 slope has "some potential for slope movements". This is unacceptable because this will be the only route to the homes on the hill. The maximum allowable slope is 2:1, and as a result, the grading plan in this area must be updated to reflect 2:1 is • • i r i Il. 12. 13. 14. s 15. 16. 17. slopes. Retaining walls may be necessary in this area to keep the maximum slope of 2:1. Please clarify note 6, sheet 2, of the Bates Engineering drawings. Sheet D13 of the Bates Engineering drawings shows a chain link fence detail that is not indicated on any of the site plans. Please indicate where it is proposed or remove the detai I. Please provide sheets L 1.01 and L 1.02 for review. Drainage pipes located on Sheet 6 of the Alpine Engineering (AE) drawings should be extended to the drainage channel. The pipe extending from the water tank on sheet 7 of the AE drawings towards the northeast then crossing the access roads should be labeled. RCP pipe is required for drainages that cross beneath the ROW. The Typical Subgrade Road Section (17+75 to 27+50) on sheet 16 of AE drawings must include the 2' wide shoulders required by the PUD design guidelines. If you have any comments or questions about this letter, please give me a call at (970) 748-4045 and we can set up a meeting.

AYERS 303 5757555 ' MUNSEY(!;OTTENJOHNSON.COM • Based on our April 4 telephone discussion, and pursuant to paragraph 5 of your February 15, 2008 letter to Kent Kriehn, this letter formally requests a two year extension of the Filing 4 Preliminary Plan approval through and including June 27, 2010. By copy of this letter to. Patty,McKenney, 1 also am submitting this request to the Town Clerk as your February 15 letter directs. Separately, in a letter that will follow this request for extension, I would like to confirm and.expand upon our April 4 discussion by outlining a proposed approach to enable construction of the water tank,-access road, wetlands mitigation, and related public improvements during,the period of extension and prior to final action on the Filing 4 Final Plat and associated subdivision improvement agreement. Section 16.24. 100 of the Town Code requires that no final plat be recorded until either (a) the requisite public improvements have been installed pursuant to clause (1); or (b) collateral has been provided to assure completion pursuant to clause (2). Based on clause (1), I inquired with you as to whether it would be possible. for construction of the Filing 4' improvements to proceed without having to first obtain approval and recordation of the Final Plat. Your provisional answer, subject to working through the details and confirtniing.internally, was that this should be possible. We view this as a very productive discussion to pursue. Therefore, we would like to confirm that this approach is viable and to further confirm what the permitting and related requirements will be so that Traer Creek Metropolitan District can be in a position to proceed with its bond issuance with assurance that it can proceed with construction promptly following the bond closing. To that end, I will submit a letter to you that outlines the process as we see it. We then would like to obtain the Town's written comments on and, after incorporating any supplemental or modified information that you believe pertinent,'concurrence with that process. It would be our expectation that the foregoing will provide a framework for the developer and the Town to work 950 SEVENTEENTH STREET SUITE 1600.

In the letter, you requested a 2-year extension of the The Village (at.Avon) Filing 4 Preliminary Plan approval. The extension request does not show "good cause" pursuant to Avon Municipal Code (AMC) .16.20.110. Please submit a revised request letter in compliance with AMC 16.20.110, and Staff-will schedule the extension request for Town Council hearing. Staff will only support a I-year extension of the Preliminary Plan if the extension request meets the requirements of such good cause. On March 25, 2008, Staff received a copy of the attached July 2001 Cultural Resource Inventory Report (Report) that was prepared by Metcalf Archeological Consultants.of. Eagle. The.report was prepared for Traer Creek LLC and was a requirement of CDOT to construct the Post Blvd interchange. The Cultural Resource Inventory Report identified 9 sites within the Village at Avon, of these two may be eligible for the National Register of Historic Places since they hold some data potential. One of the sites along Nottingham Gulch (identified as 5EA1736 in the report) may be located within the area to be disturbed for the construction of the Filing No. 4 improvements. The report states that data recovery of the site is a feasible option since it is not located where in-situ preservation.is the best option. The Report only provides a general location for the site. As a result, Staff attempted to visit the site to better determine the location arid impacts of the Filing 4 construction but was unable to do so. Staff is recommending that a condition be added to the Filing 4 Village at Avon extension that requires an analysis of the impacts of the Filing 4 construction on the site and if there is any-disturbance in that area, that the developer undertake a data recovery of the prehistoric site. The second part of your April 16, 2008, letter relates to phasing construction of the Filing 4 improvements and the final plat and SIA. Town Staff is willing to consider your proposal to construct the Filing 4 improvements prior to recording the Filing 4 Final Plat subject to the, following conditions: First, the developer must enter into a SIA before any improvements are constructed per Section 16.24.100'(i) of the AMC, Second, Staff will not-support the Town entering into a SIA for a proposed development that is not fully funded because there must be acceptable collateral ensuring that the project will be completed. Staff will support omitting the collateralization of the tank if there is a separate agreement with the Upper Eagle Valley Water Authority that guarantees and collateralizes completion. E Munsey L. Ayers April '30, 2008 Page 2 of 2 Please submit a proposal that clearly outlines how the developer would like to fund and phase the SIA and that complies with the AMC. If you have any comments or questions about this letter, please give me a call at (970) 748-4045 and we can set up a meeting.

O. Box 975 Avon, CO 81620 Re: The Village at Avon Filing 4; Water Tank Dear Justin: As contemplated by my April 16, 2008; letter requesting a two year extension of the Filing 4 Preliminary Plan • approval, this letter outlines a proposed approach to enable construction of the water tank, access road, wetlands mitigation, and related public improvements during the period of extension and prior to final action on the Filing 4 Final Plat and associated subdivision improvement agreement. Also, as detailed below, this letter responds to the main points your April 30 letter as follows: • "good cause" pursuant to AMC Section 1 6.20.100 for requested 2 year extension: The referenced section provides not direction regarding what might constitute "good cause.". As described more fully below, this is simply, a very pragmatic request based on the fundamental reality that there is no present ability to provide the funding necessary to construct the tank improvements that the Town (in our opinion, inappropriately) has asserted must be collateralized through an SIA as condition of final plat approval and recordation. The requested 2 year extension serves to good causes in that (1) it avoids the need for the parties to engage in!a dispute regarding the proper scope of collateral ization and the proper scope of public improvements serving the lots created by the plat; and (2) it enables what we view as adequate time to put in place the, arrangements to fund and commence construction of the tank site improvements and complete processing of the final plat without further need for extension. With regard to point (2) above, as the discussion below should demonstrate, a I-year extension is not adequate. • Condition regarding archeological site: We previously have addressed this issue through the Metcalf report mentioned in your letter.and are generally amenable to reasonably addressing this issue consistent with the report and generally applicable AMC requirements in like manner as the Town requires of other developments. As to the proposed condition, we would have to see and evaluate the language and hope to work through that with staff in a cooperative manner. Additionally, since we anticipate that permits must be issued by 950 SEVENTEENTH STREET SUITE 1600 DENVER COLORADO 80202 P 303 825 8400 F 303 825 6525 oTTEN10HNSON.COM DENVER ASPEN VAIL VALLEY STEAMBOAT SPRINGS Justin Hildreth June 18, 2008 Page 2 the Town prior to commencement of any work on the tank site improvements; including any grading activities, we believe the condition you propose would more appropriately be incorporated as a requirement of the permit itself, and that adding it as a condition of the extension may well be premature. • "Fully funded" S1A collateralization: I do not understand your interpretation of AMC Section 16.24.100, as your statement that a fully funded SIA must be in place prior to construction of the public = . improvements is directly contrary to the actual language which states that no final plat can be recorded until either the public improvements have been installed (per clause (1)) or collateral is in place to assure completion (per.clause, (2)).: Your letter seems-to focus only on clause (2). As described below, we are proposing to proceed pursuant to clause (1). By way of context, Traer Creek Metropolitan District's ("TCMD") ability to' fund these public improvements is contingent on its ability to issue one or more new series of bonds, or to arrange for alternative financing sources ("Tank Sife Financing"). TCMD's ability to secure the Tank Site Financing will be confingent'on, Commiiments from users for additional commercial development within The'Village (at Avon).. In turn, securing the Tank Site Financing and commitments for users within the next phase of commercial development each are predicated on the ability to obtain the necessary constructionand'grading'permits'from the Town'of ' Avon for both the water tank improvements and the vertical construction within'the next phase of comrercial`: development. These logistical impediments and associated timing difficulties have*created the "chicken and'' egg"'issue that has complicated our discussions regarding the subdivision improvement agreement for the Filing 4. Final Plat., Based on our April 4 telephone discussion regarding a process to obtain the'necessary construction and grading permits prior to approval and recordation of the Filing 4 Final Plat, this letter outlines the process as the developer and TCMD envision it, identifies issues with respect to which we are requesting direction and concurrence from the Town, and seeks the Town's written confirmation of the process in order that TCMD may be in a position to rely on this process in marketing its next series of bonds to finance construction of the water tank and related public improvements. Once we have reached and documented a mutual understanding regarding this approach and the developer has obtained sufficient commitments for users within the next phase of retail development, TCMD will be in a position to promptly proceed with the Tank Site Financing. Once TCMD has funds available, it will be in a' position to commence construction of the, Work (defined below), complete processing of the Filing 4 Final Plat, and provide any assurance of completion that may be required'at the appropriate'time. TCMD would be able to proceed with construction of the Work without the Filing 4 Final Plat having been approved and without having to provide assurance of completion, and potentially to complete all'or a part of the Work prior to Filing 4 Final Plat approval or vertical construction within The Village (at Avon). However, assurance of completion for any uncompleted portions of the Work would be required in connection with the earlier of: (a) Filing 4 Final Plat/subdivision improvements agreement; or (b) granting of a building permit for vertical construction within affected areas of The Village (at Avon). The scope of work anticipated to be financed and constructed pursuant to the Tank Site-Financing is set forth in Appendix A (the "Work"). The Work will be performed in accordance with construction plans and 0 Justin Hildreth June 18, 2008 Page 3 specifications submitted to and approved by you, in your capacity. as Town Engineer; prior to commencement of construction (as revised from time to time and approved by the Town upon request of the developer aitd/o"r TCMD, as applicable, the "Approved Plans"). The Work will be completed in phases, as described in Appendix B. Phase I consists of two.subphases, designated as the Traer Creek Run Subphase and the Wetlands Mitigation Subphase. Phase II also consists of two subphases, designated as the Regional. Tank Access Road Subphase and the Water Storage Tank Site Improvements/Holy Cross Access Road Subphase. The Approved Plans will be substantially consistent with The Village (at Avon) August 2006 Final Plans set forth in Appendix C ("Plan Set"), consisting of: (i) Cover Sheet; (ii) Grading and Drainage Plans, sheets 2 though 21, prepared by Alpine Engineering,. Job No. 8206; (iii) Landscape Plans and Visual Analysis, sheets 1-1.01 and L1.02, prepared by. VAg,.Inc., Project No. 2534; (iv) Culvert Headwall Plans, sheets HW-1 through HW-4, prepared by Golder Associates, Project No: 053-2363; (v) Retaining Wall Plans, sheets 'RW-1 through . RW-9, prepared by Golder,Associate5, Project No. 053-2363A2; and (vi) Tanks_Plans (including Tank Details, Tank Piping, and Telemetry, Instrumentation and Control Layout, sheets S-1'through 522, D1. through D13, P1 through P8 and.11, prepared by Bates Engineering, Project No. 04:026. 'As discussed below, the Plan Set is in the process of being revised in response to your prior comments, and we will forward the next iteration of the Plan Set for your further review When the revisions have been completed. • Based on the foregoing, our understanding of the process going forward would be as; follows: • • Required Third Party Approvals. Pursuant to item 6 of your February 15, 2008, letter, updated approval letters will be required.from the_following organizations: • U.S. Army Corps of Engineers, with respect to the Wetlands Mitigation Subphase of Phase I. • Eagle River Water and Sanitation District, with `respect to (a), the "Water" category within the Traer Creek Run Subphase of Phase 1; and (b) Phase 11. • The Village (at Avon) Master Design Review Association, with respect to any component of the Work for which a building permit is required to be issued by the Town. • Plan Set/Approved Plans. Certain of the following issues identified. in your February 15, 2008, letter are pertinent to your approval of the Plan Set/Approved Plans, while others are pertinent to the Filing 4 Final Plat or other anticipated development. We anticipate that you will complete your review and fnalize your approval of the Plan Set/Approved Plans generally along the following lines: • items 6 through .17 of your February 15, 2008, letter to Kent Kriehn set forth. certain relatively minor issues that will need to be resolved before you, in your capacity as Town Engineer, would be in' a position to recommend approval, of the Filing 4 Final Plat. In order to enable you to approve the Plan Set as contemplated herein, our responses are as follows: 0 • Justin Hildreth June 18, 2008 Page 4 • ' ' Item 6 - Updated approval letters from: • Army Corps of En ineers: The previously issued Section 404 permit has expired. Reaching an.understanding with you regarding the process discussed in this letter and, based on that understanding, obtaining a better"sense of when TCMD will be in, a position'to,actually proceed with the Work from a procedural standpoint, will put us in a position to proceed with obtaining a new permit and approval letter for the Wetlands Mitigation Subphase. While we are prepared to undertake steps to resolve those items with the Corps, we hope to coordinate those efforts so that the Wetlands Mitigation Subphase can be accomplished within the term of the newly issued permit. Therefore, it is necessary to reach resolution with you regarding the process for obtaining the necessary Town approvals so that we can coordinate these processes effectively. • Eagle River Water and Sanitation District: The Plan Set is being revised in response 6 yogr comments and comments from the service provider. Therefore, we anticipate having this approval letter once the current revisions have been reviewed and approved. • The Village (at Avon) Master Design Review Association: Written approval will be obtained-once the Plan Set is finalized and you have indicated that-you are in a position to approve. Jt is my understanding that this approval letter is needed for issuance of building permits per the terms of the • annexation agreement, but not for approval of the Plan Set. In any event, we do not anticipate any delays or issues on this approval letter. • Item 7 - Reflect 2008 date on Filing 4 Final Plat: Based on the approach contemplated' in this letter, the date on the Filing 4 Final Plat will be updated in the future to reflect the current date at the time of final action by Town Council on the Filing 4 Final Plat. The revised Plan Set will be dated current. • Item 8 - Relocating 100' electric easement to correspond to actual power line -location: We see this as a Filing 4 Final Plat issue, and not an issue pertinent to final approval of the Plan Set/Approved Plans. Therefore, we will work with Holy Cross to resolve this by a private easement prior to completing the Filing 4 Final Plat process so that the revised easement can be properly reflected in the Filing 4 Final Plat. We anticipate that this will be by separate easement document rather than a plat dedication, but that the plat will reflect the revised easement area. In the mean time, however, we do not view this issue as impacting your ability to approve the Plan Set/Approved Plans. . o Item 9 - Inclusion of sanitary sewer in utility plans: The Plan Set contemplates that the Traer Creek Run Subphase will'be an interim, unpaved road. Prior to platting of residential' lots that will be accessed by this road, it will simply provide access to the water tank site for constriction and subsequent maintenance and operations purposes. It will be constructed in the final alignment and.in compliance with applicable requirements to facilitate final paving, but will not include utilities that are not necessary for operation of the water tank. Prior to paving, the water district will have an access easement. Sanitary sewer and any other utilities necessary to serve the residential lots will be installed at a later date when this segment of the road is paved to provide public access to the residential lots. In 0 Justin Hildreth • June 18, 2008 Page 5 sum, the final road improvements would be accomplished in connection with the initial final plat for residential development serviced by this road, and not in connection with the Plan Set/Approved Plans or the Filing 4 plat. • Item 10 -Update grading plan for maximum 2:1 slope/retaining walls: This will be addressed in the revised Plan Set. • Item 11 - Clarification of Note 6, Sheet 2, Bates Engineering drawings: This will be addressed in the revised Plan Set. • . Item 12 -Chain linkfence per Sheet D13 of Bates Engineering drawings: This will be addressed in the revised Plan Set. • Item 13 -Provide Sheets LI.Oland L1.02 for review: This will be addressed in the revised Plan Set. • Item 14 - Extend drainage pipes shown on Sheet 6 of Alpine Engineering drawings to drainage channel: This will be addressed in the revised Plan Set. • Item 15 - Labeling ofpipe shown on Sheet 7 of Alpine Engineering drawings: This will • be addressed in the revised Plan Set. Item 16 - Reflect RCP pipe for ROW crossings: This will be addressed in the revised Plan Set. • Item 17 - Incorporate 2' wide shoulders in Sheet 16 of Alpine Engineering drawings: We anticipate that this will be addressed by modification of the typical sub-grade road section, per the Town's request, to incorporate the 2' wide shoulder. As reflected in the above discussion regarding item 9, this will be accomplished through the final plat approval process for the residential lots to be serviced by the final construction of the road and conversion from temporary private access to the water tank site to public access to the residential lots. • Once the foregoing matters have been resolved to your satisfaction, you will provide written documentation of your approval of the Plan Set. Once that approval is granted, the Plan Set would become the Approved Plans. • Subject to obtaining all required permits and third party approvals, as outlined herein, TCMD would be authorized to proceed with financing and construction of the Work, in phases as described herein, in accordance with the Approved Plans. Except upon request of TCMD and/or the developer, as approved by the Town, the Approved Plans would not be subject to further modification. 40 • Justin Hildreth June 18, 2008 Page 6 • Required Permits (Town of Avon). Upon satisfaction of the foregoing, and upon receipt of a complete application from and payment of applicable fees by the developer and/or TCMD, the Town would issue the following permits: e Grading Permits for each Phase or Subphase, as applicable, which would authorize all - excavation, site"grading, cut,'fll, compaction and erosion control measures associated with the relevant Phase or 'Subphase, inclusive'of any road construction, utility installation and retaining wall construction. • Building Permit for construction of the Water Storage Tank component of Phase ll. • A permit authorizing work to be performed in the public right of way'may be required in connection with tying the Traer Creek Ruin Subphase to existing improvements extending north from the interchange and roundabout. . • No further or additional permits would be required from the Town" of Avon. However, we may have to obtain permits from other entities, such as a state storm water permit. Y Tank Site Financing. • Once you have issued your written approval of the Plan Set and the developer has obtained sufficient commitments from additional retail users to enable TCMD to underwrite a new series of ;bonds, TCMD will proceed with the Tank Site Financing in reliance on the Approved Plans and Town assurance of ability to obtain permits form the Town as described above. In connection with the Tank Site Financing, the Town will provide written confirmation of TCMD'.s ability to obtain the' permits (if not previously obtained) and commence the Work as outlined above, ' which written confirmation may include an opinion letter from the Town's legal counsel with respect to the, foregoing and other matters required by bond counsel. • Proceeds from the Tank Site Financing will be deposited in a TCMD account, in accordance with the bond indenture, for the specific purpose of financing construction of the Work. • The foregoing account will be available to provide assurance of completion of the Work in satisfaction of the subdivision improvements agreement requirements in conjunction with Town approval of the Filing 4 Final. Plat or issuance of building permits for vertical development within The Village (at Avon) as described below. Vertical Construction Within The Village (at Avon). • Prior to TCMD obtaining the Tank Site Financing, further vertical development within residential and commercial areas of The Village (at Avon) may occur only with written verification from Eagle River Water and "Sanitation District of its ability to serve such vertical development without completion of, or 0 Justin Hildreth June 18, 2008 Page 7 upon commencement of construction of, the water tank; provided,, however, that the foregoing shall not apply to construction of the emergency services'faciiity within.Planning Area N. • Prior to approval of the Filing 4 Final Plat, execution of the associated subdivision improvements agreement and provision- of assurance of'completion for the Work, issuance of building permits for vertical construction within The Village (at Avon).(other than the.emergency.services faciliry.within Planning Area N) will be conditioned on the applicant or TCMD providing assurance. of completion of the water tank. Final certificates of occupancy will not be granted until substantial completion of the water tank and preliminary acceptance of the water tank by Eagle River Water and Sanitation District. • After approval of the Filing 4 Final Plat, execution of the associated subdivision improvements agreement and provision of assurance of.completion for uncompleted portions of the Work, issuance of building permits for vertical construction within The Village (at Avon) will be granted upon the Town's receipt of a complete submittal, payment of applicable fees, and compliance withapplicable building codes. Final certificates of occupancy will be granted in accordance with the Town's generally applicable regulations. Approval and Recordation of Filing 4 Final Plat. C Concurrently with obtaining the Tank Site Financing, or at any time thereafter prior to expiration.of the Preliminary Plan approval (as extended), the developer and TCMD will complete processing • of, and the Town Board will take .final action on, the7Filing 4 Final Plat and related subdivision improvements agreement. • Assurance of completion of the Work will be provided as required in the subdivision improvements agreement:- and may be satisfied by the funds being maintained by TCMD in a. dedicated account with respect to which, the Town will have access in the event of a default by TCMD of its obligations under, the subdivision improvements agreement. Miscellaneous. • We anticipate that the procedures for inspection and acceptance of the Work will occur by subphase. To the extent that. TCMD has provided collateral to assure completion or warranty collateral,-such collateral will be released:upon preliminary, or final inspection and acceptance, as applicable. 0 _ Any portions of the Work to be dedicated to the Town or TCMD will be subject to. generally applicable Town standards for inspection, acceptance, warranty periods, warranty collateral and similar matters. • TCMD will retain ownership and maintenance responsibility for the portions of the Work within the Traer Creek Run Subphase and the Wetlands Mitigation Subphase (and potentially including some or all retaining walls within Phase II). . E • Justin Hildreth June 18, 2008 Page 8 • Portions of the,Work to be dedicated to utility providers (and not to the Town) will.be subject to the generally applicable-standards of the applicable utility provider with respect to inspection, acceptance, warranty period, warranty collateral and similar matters. While it is my hope that this letter provides a good outline of the potential process, I also recognize that various of the points discussed above will require further discussion and mutual effort to reach a final resolution. Please review and provide your feedback on the foregoing. 1 should also point out that working through those points should not require delaying. action on-the requested 2 year extension and, in point of fact, is part of the rationale providing "good cause" for the 2 'year request. The 2 year extension will enable sufficient time to work through the necessary details to implement the approach we are proposing, and to thereafter enable TCMD to obtain the funds that will enable construction to commence and processing of the final plat application to occur as generally described above. Again, thank you for your efforts to work through these issues and achieve "a workable solution that addresses the practical realities while also addressing the legitimate and reasonable objectives and needs of the Town, TCMD and the developer. .
