BOARD OF COUNTY COMMISSIONERS �������� WELD COUNTY, COLORADO ATTEST: L /�'!/YG EXCUSED William H. Jerke, Chair Weld County Clerk to the Board C\13-\ l Robert D. Masden, Pro-Tern BY: F1LIG� =r LF C�L�e�/ Deputy Clerk the Board William F. Garcia APPR¢GED AS b w�� C David E. Long ounty At rney — o Doug; Rademac r Date of signature: 9Af 2008-1525 PL1765 I appreciate the opportunity to speak with you today concerning this project. The project basically started in 2004. The original design included 8 lots on approximately 115 acres ranging in size from 3.5 acres to 80 acres. Three of the lots boarded the Nazarenes Ditch. In December 2004 I went before the planning commission for change of zone. At that time there was significant opposition from the Nazarenus Ditch Company concerning the 8 lots and the impact on the approximately 5 foot wide and3 foot deep ditch. This ditch also has a 120 foot right of way on the West side of it and a 50 right of way on the East side of it. As a result of the potential impacts to the ditch company, I moved the lot lines to the far West edge of the right of way and redesigned the plan so there were only three lots instead of four boarding the West edge of the right of way. Thus reducing the lot sizes and potential income and increasing engineering and surveying costs. This left the 120 foot right of way access free solely for use by the ditch company and the owner of the larger 80 acre lot. In March of 2005 I came belbre this board for a change of zone hearing. At that time this board required me to enter into an agreement with Nazarenus Ditch Company addressing: • . -review of drainage plan - fencing type -maintenance of the strip of ditch right-of-way - ditch company access The Nazarenus Ditch Company hired an engineer to review and design the drainage plan. This was in addition to the public works review the county required. The requirement by the county commissioners to get an agreement with the ditch made it impossible for me to get approval through the county until I met all the Nazarenus Ditch Company design criteria demands. EXHIBI In T ViLe t jcc'?- lsas - Z • In addition, the agreement with the Nazarenus Ditch Company was to include fencing type, maintenance of the strip of ditch right-of-way and access. This added to the impossibility of moving the project forward without the ditch company approval. These were the impacts that I tried to avoid by moving lot lines off the right of way after opposition was expressed at the planning meeting. The ditch company was in opposition of this project from the start. With that in mind the requirement for me to get an agreement with the ditch company gave them the ability to dictate all design aspects and increase cost for all four of the items the county wanted addressed. Indirectly the county gave the ditch company the ability to require higher standards and implement lofty design criteria that the established county codes were designed to address. If there is any doubt about the authority the ditch company perceived they had, a letter dated February 29th 2008 by the Ditch Company Attorney demonstrates their perceived power by requiring the applicant to: -provide a performance bond in the amount of$20,000 and an additional $2,500 for professional services, installation per design standards. - to limit the applicant to one crossing and that no other crossings be allowed in the County right of way. - to require the applicant to provide liability insurance coverage in adequate and proper amounts on behalf of the Nazarenus Ditch Company with premiums to be paid by the developers or some type of homeowner's association which will be kept in full force and effect with proof of payment of the premiums. -to hold the ditch company not responsible or liable for any losses that occur to livestock or from other damages or losses incurred from their usage of lot 4. - require the applicant to install at her or her successors in interest sole expense and cost, any fences and all fences and gates requested by the ditch company and at reasonable and mutually agreed upon locations. The developer or her successors in interest shall take necessary measures to timely; adequately and properly maintain proper drainage to prevent erosion of the surface of such easement premise. The very nature of the ditch company demands would give an indication that the ditch company believed they were given the authority rights granted to the county by law. It would also suggest they were granted the full rights of the landowner without the cost and liability associated with developing this project. In spite of this, there were also other issues concerning drainage. The county requirements concerning urban drainage standards for land owners desiring to create non urban scale planned unit developments added financial impacts to this project. The drainage concerns could have been easily addressed using a less restrictive or rural standard. In fact they probably should have taken into consideration the impact of 8 lots on 115 acres. My engineer Brain Shear of Shear Engineering in Fort Collins indicated to me yesterday that they have never had to build non urban scale planned unit developments to urban drainage standards. The costs verses the benefit associated with building a nine lot non urban planned unit development to urban drainage standards is cost prohibitive as evidenced by the attached cost projections. The final item that I would like to address is the inconsistencies in reaching cost for proportionate share of offsite improvements for Weld County Roads 55 and 72. In a letter dated July 24, 2006 from Drew Scheltinga he indicated my proportionate share of paving would be $49,000. In another letter dated June 07, 2007 from Jesse Hein and Brain Varrella my proportionate share of$49,000 was reiterated. On or about June 23, 2008 I had a phone conversation with Brian Varrella where he indicated the cost would be $76,000. 1 asked him to send me the proposed changes in writing. In January of 2008 after I paid for a new traffic study and provided the information to Brain Varrella, I received a letter from Brian Varrella indicating that my proportionate share would now be $122,000. There were also additional costs in the amount of$15,758 for road stabilization for Weld County Road 55 and $10,224 for Weld County Road 72. This brought the offsite agreement amount to $147,982. Please see cost projections from the improvement agreements. On March 21, 2008 my engineer and I met with several members of publics works to discuss proportionate shares for paving and dust abatement. In that meeting I proposed a non refundable fee in an amount between $ 40,000 and $50,000. On April 22, 2008 I submitted a letter and improvement agreement proposing a $ 40,000 non refundable cash payment in lieu of offsite improvement agreements for Weld County Roads 55 and 72. On May 9, 2008 I received a letter from Brad Mueller indicating that public works wanted $113,724 in cash in lieu of offsite agreements. Please see attached letter dated May 9, 2008. It is important to note the inconsistencies associated with offsite improvements as another element that brought this process to a close. I understand that deciding land use cases are difficult and respect the fact that the decisions you make in attempting to facilitate amenable outcomes without compromising the health and safety of the residents of Weld County and the codes that govern development. However, consideration has to be given to the fact that the ditch company was given the latitude to place restrictive requirements on the development that were unwarranted and significantly increased the cost of finishing this project. In reference to urban drainage requirements the design and the restrictive covenants associated with them are not realistic for non urban scale projects. Logically, one would have to consider the value of this type of design criteria in a rural application. Finally, the inconsistencies in applying a dollar amount to offsite improvements need to be addressed. A landowner cannot be expected to complete a project of this type when costs cannot be locked in. I have spent over$100,000 on this project. I am not willing to spend hundreds of thousands more as a result of the issues outlined above. I urge you to consider the impact of these types of issues on farmers and ranchers of Weld County who have the desire or need to develop their property in the future. Consideration must be given to making the necessary adjustments in policies and procedures to mitigate these problems. Thank you. MELVIN DINNER, P.C.

As you will note from examination and review of your records, I have heretofore submitted correspondence to you relative to this matter dated August 29, 2006, together with copy of a report dated August 22, 2006 prepared by Don Dunker, P.E.. Engineer retained by the Board of Directors of the Nazarenus Lateral Ditch Company. Mr. Dunker has offices located at 33504 WCR 53, Gill, CO 80624. The information provided in August of 2006 was with reference to matters dealing with the drainage report and construction drawings for the Lawley Estates PUD and its potential impact on the Nazarenus Lateral Ditch and the right of way system. Mr. Foss, the Secretary for the Nazarenus Lateral Ditch Company, has recently made available to me a set of nine sheets pertaining to the construction plans for Lawley Estates PUD prepared by Shear Engineering Corporation with offices located at 4836 S. College Avenue, Suite 12, Fort Collins, CO 80525 on behalf of Mark and Sherry Lawley, which documents indicate that a similar copy of this material was received by the Weld County Public Works Department on January 3, 2008. It is my understanding that a similar copy of this engineering project and the construction plans for Lawley Estates PUD were similarly provided to Mr. Dunker. February 29, 2008 Page 2 It is also my understanding that you have requested comments from the Board of Directors and Shareholders of the Nazarenus Lateral Ditch Company pertaining to the set of documents prepared and/or submitted by Shear Engineering Corporation to the Weld County Public Works Department on January 3, 2008. Based upon the latest documentation submitted by Shear Engineering Corporation and a review of this material by Don Dunker, P.E., as well as the Board of Directors and Shareholders of the Nazarenus Lateral Ditch Company, I am submitting herewith on their behalf the following: 1. Copy of letter report dated February 9, 2008 submitted by Don Dunker, P.E. to the Nazarenus Lateral Ditch Company in connection with matters required prior to any approval of the construction plans for Lawley Estates PUD. At the annual meeting of the Shareholders of the Nazarenus Lateral Ditch Company held on February 16, 2008 the Shareholders and Board of Directors have indicated the following items would be required for approval to be provided to the Lawley Estates PUD plans. 2. All of the items in the letter as outlined by Don Dunker, P.E. in his letter of February 9, 2008 should be required and shown on the engineering plans and all of which must be performed as part of the approval project. 3. Sheet 1/2 of the documents for the Lawley Estates PUD PF-1043 prepared by Coffey Engineering & Surveying, LLC describes a portion of Lot 4 which is the Nazarenus Lateral Ditch and the roads within the easement area utilized for the ditch company; this easement area is solely for the use of the ditch company and not for use by other individuals or other entities. 4. As you will note from information and documentation which has heretofore been presented to you, there is to be a suitable, proper and adequate fence approved by the ditch company to be constructed at the sole cost of Sherry Lawley and/or Mark and Sherry Lawley on the west side of the right of way of that portion of Lot 4 as shown on this Sheet 1/2. The remaining portion of Lot 4 which lies to the north of the right of way and ditch location is currently undeveloped and is not a part or portion of the present development project of Lawley Estates PUD PF-1043. It is my understanding that neither Mr. or Mrs. Lawley have any ownership of what is described as Lot A of Recorded Exemption No. 0801-4-4 RE3581 and this is not shown as part of this project on Sheet 1/ 2. It is also my understanding that there is a fence or a fence to be constructed along the north border of this Lot A as well as along the east side of the right of way of Lot 4 as shown on Sheet 1/2 of the document submitted. February 29, 2008 Page 3 I enclose for your benefit the following: (a) Copy of Warranty Deed dated July 19, 2002, recorded July 22, 2002 at Reception No. 2970916 of the Weld County records executed by the Nazarenus Lateral Ditch Company, a Colorado corporation, as grantor, to Sherry Lawley, as grantee, covering the following described property located in Weld County, Colorado: N/2SE/4 and SE/4SE/4 of Section 4, Township 6 North, Range 64 West of the 6th P.M., Weld County, Colorado (b) Copy of Right of Way and Easement Agreement dated July 19, 2002, recorded July 22, 2002 at Reception No. 2970917 of the Weld County records between the Nazarenus Lateral Ditch Company, a Colorado corporation, as First Party, and Mark Lawley and Sherry Lawley, as Second Party. 5. It will he the obligation and responsibility of the ditch company to provide the maintenance services as required within the right of way and easement area. 6. Outlot B. As you will note from examination and review of the plans, Outlot B as indicated on the plans containing 26,943 square feet or a total of 0.85 acres is the location for a planned detention pond to be constructed by the Developers. In connection with the construction work to occur and the long-term maintenance problems that could impact the right of way and the Nazarenus Ditch the Board of Directors and Shareholders of the Ditch Company believe that a proper solution in order to keep the Lawley project moving forward would be to have the developers obtain and provide a performance bond to the Ditch Company in an amount of not less an $20,0 . 0 for and on behalf of the Ditch Company, together with a letter of agreement. In event the plans are not followed and any damage occurs either during construction or for a period of at least three years after construction, that the_performance bond would be capable of thus providing directions for payment for damages that would occur to the ditch, the right of way and to the shareholders who use the ditch, such as crop losses, etc. , ,:_.x Ac w 1- h cn..a cL;' � [�,..x ,L�2 i"�.r� wait w��1.7 21~�rtc. 4...-..� ((��rr cvJ ly (/YLck 1 w0 .ry<y.;..u..L 7. Crossing of the Right of Way. The Nazarenes Ditch or Lateral has a culvert which goes underneath Weld County Road 72. As you are well aware, Weld County Road 72 is a public right of way 60 feet in width. Based upon the engineering plans as provided, it appears that if there is overflow drainage from what is described as the Outlot B Retention Pond, the overflow drainage would go subsurface underneath the Nazarenus Ditch and right of way in an easterly direction, eventually going into a barrow pit located east of the right of way and Nazarenus Ditch or Lateral. The ditch company is requesting the payment of a sum of not less February 29, 2008 Page 4 u i,L V +nn ` cAptrpi- O1° trb N �u d cr ydil s t than$2,500.00 in order to provide for the capability of providing for professional services to oversee the construction matters dealing with thirossiiig. The plans pertaining to the crossing to be made within Weldtounty Road-7-2 under the right of way and ditch lateral need to provide that proper and adequate notice is provided to the Nazarenus Lateral Ditch Company in advance so that representatives and professional personnel on behalf of the ditch company can he present and available where the pipe for the overflow is to be constructed beneath the Nazarenus Ditch or Lateral and right of way underneath the culvert providing irrigation water for the ditch company and through the right of way. The plan should also provide that approval for the crossing by the developer or any other entity underneath the ditch is limited to this one crossing and that no others in the County right of way be allowed. There is no provision as of the present time to the best knowledge of the Ditch Company for any allowance or approval of any other crossing of the ditch either above the surface or below the surface of the ditch and right of way. 8. Portions of undeveloped Lot 4 lying to the north of the Lawley development project. Portions of Lot 4 of the Lawley Estates PUP project lie north of the developer's project on both sides of the Nazarenus Ditch or Lateral. The Nazarenus Ditch or Lateral at this location, as well as the area south of this location, is presently a concrete structure. Mr. and Mrs. Lawley intend to pasture livestock in this area. " ' r � , J-�} + <,)c-1-L 4 ��--.,.�_e �. tom- i_ Some years prior the Nazarenus Lateral Ditch Company constructed a surface bridge across the ditch in order to have access from west to east and east to west across the ditch area in that portion of Lot 4 of the Lawley Estates PUD which is not presently being developed. Lawley Estates PUD and this Lot 4 actually owns portions of Lot 4 on both sides of the Nazarenus /\ Lateral Ditch in this area. Livestock being pastured on the Lawley property could apparently utilize this bridge to go from one side to the other. It would also appear that at the north end of that portion of Lot 4 which is adjacent to what would be Lot 2 and Lot 3 that access is potentially available to livestock and other sources; accordingly it would appear under the circumstances • TA that the plans for the Lawley Estates PUD needs to provide for providing liability insurance �G coverage in adequate and proper amounts on behalf of the Nazarenus Lateral Ditch Company with the premiums to be paid by the developers or some type of homeowner's association which will be kept in full force and effect with proof of payment of the premiums. .- ( - Gc 5.i& a.0 t--/-1_t--/-1_ a.) (x.- —L(6x] - ci LIC , n - 9. The Lawley Estates PUD provisions should clearly provide that the Nazarenus Lateral Ditch Company shall not be responsible or liable for any losses that occur to livestock or from other damages or losses incurred from their usage of Lot 4. 10. That Sherry Lawley or any successors in interest shall install, at her or successors in interest sole expense and cost, any and all fences and gates requested by the ditch company and at reasonable and mutually agreed upon locations. That the Developer or her successors in , .�V 'LA(T. Cli Iii.'.)

I suggest that after you have had an opportunity to review these matters that you contact me, as well as Don Dunker, the Engineer who is currently representing the ditch company, in connection with these matters. As you will note, I am also submitting a copy of this correspondence to Mr. Dunker, to the Nazarenus Lateral Ditch Company and to G. Brent Coan, of the law firm of Otis, Coan and Stewart, LLC, who has heretofore been representing Mrs. Law-ley.

Drainage Comments: u Public Works received a Final Drainage, Erosion Control, and Water Quality Report for Lawley Estates PUD (PF-1043) on May 16, 2007. The report was submitted by Brian W. Shear, P.E. #20262, of Shear Engineering Corporation, and is dated May 2007. This report will herein be referred to as the Final Drainage Report. ❑ The Final Drainage Report is stamped, signed, and dated by a registered P.E. licensed to practice in the state of Colorado. All construction plan sheets included as attachments to the Final Drainage Report must be wet-stamped, signed, and dated by a registered P.E. licensed to practice in the state of Colorado. All construction drawings included in the final plan set must be wet-stamped, signed, and dated by a registered P.E. licensed to practice in the state of Colorado. u Shear Engineering has prepared a good drainage report that is well documented and supported with engineering calculations. Public Works appreciates the clear level of effort that was placed in the report. Please address the few outstanding comments as follows: 1. The applicant has proposed the construction of a pipe under WCR 55, and is required to submit an offsite improvements agreement to Weld County. Appropriate right-of-way permits must be approved prior to construction in the County ROW. a. The outlet of the detention pond pipe may not discharge to or be constructed on private property without the written consent of the affected property owner(s). Please provide copies of all necessary written permission in the appendix of the Final Drainage Report. 2. The Final Drainage Report proposes only partial detention of onsite developed flows. The total property is approximately 114.3 acres, but the subdivision lies on 29.7 acres of the property. Lot 4, as shown on Sheet 6 of 9, is 83.8 acres, and borders the 8-lot subdivision on the north and eastern boundary. a. If Lot 4 stormwater runoff will not be detained, the Weld County Board of County Commissioners must approve a variance from current County Code 24-7-130 and Ordinance 2006-7. b. If a variance is requested and approved by the BOCC, the approved detention pond size and release rate for the proposed 29.7 acre subdivision shall be calculated from the 29.7 acres only. Future development on the 83.8 acre Lot 4 will require a separate detention facility. Please note, the current detention pond and outlet structure for the 29.7 acre subdivision will be too small for future expansion on Lot 4, and retrofitting of the proposed detention pond and outlet structures will be extremely expensive. Public Works is concerned that Lot 4, if developed, will face significant difficulties trying to route flow from detention facilities on Lot 4 Page 2 0l4 'Junc 2"`T to roadside ditches east of the Nazarenus Ditch. c. A note must be added to the Final Plat stating any future development on Lot 4 shall be required to construct stormwater detention facilities. These future facilities shall be sized to detain flows from the 100-year storm falling on the fully-developed subdivision, and release at a rate not to exceed the 5-year storm falling on the undeveloped (historic) site, as per Weld County Code 24-7-130(D) and Ordinance 2006-7. 3. Please provide a figure showing the flowpaths, lengths, and slopes used to calculate the time of concentration (Tc). a. In-house calculations show the 5-year historic stormwater runoff, also known as the allowable release rate from the proposed detention pond, to be 4.56 cfs. This is 9% less than the 4.99 cfs calculated in the current drainage report. Please double-check the historic runoff values, and the associated detention pond sizing. b. It appears the calculated detention volume may include offsite flows. Current Weld County Code does not require the detention of offsite contributions; they may be passed through the system undetained. Please double-check detention calculations to include only the onsite 100-year peak inflow discharge, which shall be released at a rate not to exceed the onsite 5- year historic outflow discharge. 4. Please add an appropriate scale and north arrow to the vicinity map, as per Weld County Code 23- 2-50(C.2). 5. The swales and rundown between Lawley Lane and the proposed detention pond are not designed according to UD&FCD standards. Table MD-2 from the USDCM(UD&FCD 2001) is reproduced in the appendix of the Final Drainage Report. According to this table, proposed open channels shall not be designed with Froude numbers greater than 0.80, and longitudinal slopes exceeding 0.60%, without proper permanent erosion control. Please prove that all channels are stable as designed, or prepare appropriate permanent erosion control (revetment) solutions for these swales. 6. The 11.5% slope on the rundown into the detention pond will require grouted boulders per USDCM criteria. Please provide engineering calculations to support the appropriate rock size. As an alternative, the applicant may choose another revetment for the rundown if it can be proven stable under proposed topographic and hydraulic conditions. Alternative revetments may include, but are not limited to, articulating concrete blocks (ACBs), turf reinforcement mats (TRMs), or other reasonable solutions that are supported with engineering design calculations. 7. The current design calls for Type-M grouted riprap, per review comments from the Nazarenus Ditch Company, but the size has not been proven stable with engineering calculations. Please check for stability, using a minimum factor of safety of 1.5. a. A self-launching termination key with a design detail is required for any rock riprap protection located on the emergency overflow spillway. Please follow guidance provided in the USDCM, Chapter 4.4.2.4 (UD&FCD 2001). Another useful guide may be HEC-11, Chapter 2 (FHWA 1989). b. The applicant may choose an alternative revetment for the emergency overflow spillway if it can be proven stable under proposed topographic and hydraulic conditions. Alternative revetments may include, but are not limited to, ACBs, TRMs, or other reasonable solutions supported with engineering design calculations. 8. Please provide appropriate permanent erosion control at pipe outlets and inlets, channel bends, high shear stress channels and swales, or any other areas requiring erosion control. Engineering design calculations must be provided to support the selection of any and all erosion control measures, and must demonstrate that the proposed designs provide stable channel conditions prior to the establishment of vegetation. a. Please specify the size of all rock riprap protection at all culvert outlets for in the construction drawings, and include rock size (D5o) and apron limits (length, width, and thickness). b. Please provide engineering calculations for all culvert outlets. c. Riprap outlet protection for culverts must wrap around flared end sections to prevent local erosion and scour around the FES. 9. Please update the culvert calculations in CulvertMaster to utilize HDS-5 Chart 1, Scale 1 the Page 3 of 4 -hm.?on- proposed pipes under Lawley Lane. According to HDS-5, Table 12, the appropriate entrance loss coefficient (Ke) for a flared end section is 0.50 (FHWA 2001/2005), similar to that of a pipe with a headwall and a square edge entrance. The current Ke value of 0.20 is incorrect. a. The Manning's-n for a CMP shall be 0.025, per the Weld County Storm Drainage Criteria (WCSDC). Please update the analysis for the Lawley Lane culvert crossing. b. All culvert inlets shall include debris racks to prevent clogging due to debris accumulation and to protect the public safety. Debris racks shall be sloped at 3H:1V or flatter per UD&FCD research. 10. There must be a minimum drop of 0.1 ft through the proposed manhole on the proposed detention pond outlet pipeline. 11. Please show the 100-year hydraulic grade line (HGL100) for all pipes, and show the energy grade line (EGL100). Ensure that the design provides that the 100-year EGL is at a minimum of 6 inches below the final finished elevation of any manholes and inlet rim elevations, per WCSDC. 12. Please update the SWMM model to show the same pipe lengths as the plan set. Update all other information for consistency with the construction drawings and Final Drainage Report. 13. Please specify minimum driveway culvert sizes for all lots. These culverts may not impede flows in design ditches, and shall be sized according to the WCSDC. 14. Please include a revegetation plan utilizing approved seed mixes published in the WCSDC Addendum. This plan shall be discussed in the Final Drainage Report. 15. Please include all CUHP input and output data in the Final Drainage Report appendix.- 16. Please add the following note to the Final Plat: "Weld County will not be responsible for the maintenance of drainage related areas." 17. Please show offsite contours for a minimum of 200 ft outside property limits on construction drawing Sheets 1 of 1 (Final Plat), 4 of 9, 5 of 9, 6 of 9, and 8 of 9. 18. Please add a permanent revegetation plan for all disturbed earth. This plan shall comply with all standards defined in the Revegetation section of the WCSDC. 19. Please address all redline comments in the drainage report and on the construction plan drawing contained therein. 20. Please provide a copy of the final Water Service Agreement from the North Weld County Water • District, once signed and approved. This agreement shall be added to the appendix of the Final Drainage Report. 21. Please provide a copy of the final ditch agreements from the Nazarenus Ditch Company, once signed and approved. This agreement shall be added to the appendix of the Final Drainage Report. Recommendations The above comments are prerequisites and shall be fulfilled prior to recording the Final P/at. The applicant shall address the comments listed above during this Final Plan review process. Comments made during this stage of the review process may not be all-inclusive,as revised materials will have to be submitted and other concerns or issues will arise during further review. The review process will continue only when all appropriate elements have been submitted. Any issues of concern must be resolved with the Public Works Department prior to recording the Final Plat. PC.

Comments made during this phase of the subdivision process may not be all-inclusive, as other concerns or issues may arise during the remaining application process. Final Plan Requirements Irrigation Ditches: 1. Sections 4. A. and 4. G. of the Board of County Commissioners zone change resolution required the applicant to provide an agreement with the Nazarenus Ditch Company. A copy of the final agreement shall be provided and requirements contained in the agreement shall be reflected in the drainage report and construction plans. Improvements Agreements: 1. Section 4. C. of the Board of County Commissioners zone change resolution required the applicant to enter into an agreement with the County to proportionally share in the paving of WCR 55 between WCR 74 and SH 392 and to submit a proposed agreement. Prior to future paving, the applicant shall enter into an agreement with the County to proportionally share in dust stabilization operations on WCR 55 and WCR 72. 2. WCR 55 is presently on Weld County's 2006 dust management program. The Applicant noted that previous traffic count data was outdated, and hired Matthew J. Delich (Colorado P.E. #15263) to take three traffic counts on WCR 55 between WCR 74 and SH,392 in July 2007. The following traffic information, as documented from the Delich study, supersedes previous traffic counts on WCR 55 as follows: a. WCR 74 to WCR 72 — 328 ADT b. WCR 72 to WCR 70 —472 ADT c. WCR 70 to SH 392 — 629 ADT 3. The average of the three counts is 476 ADT. Lawley Estates is expected to generate 76 ADT and if half the vehicles go each direction at WCR 55, Lawley Estates will add 38 vehicles to the existing counts. The proportional share to pave WCR 55 would be 38 / 514 = 7.4%. The cost to pave WCR 55 in 2007 figures is approximately $550,000 per mile. The proportional cost sharing for Lawley Estates would then be $122,000, as calculated at Public Works on October 16, 2007. The applicant.. is requested to amend their proposed agreement to meet the Board of County Commissioners zone change resolution using these proportions and costs. Drainage Comments: • Public Works received a Final Drainage, Erosion Control, and Water Quality Report for Lawley Estates PUD (PF-1043) on January 3, 2008. The report was submitted by Brian W. Shear, P.E. #20262, of Shear Engineering Corporation, and is dated December 2007. This report will herein be referred to as the Final Drainage Report. • The Final Drainage Report is stamped, signed, and dated by a registered P.E. licensed to practice in the state of Colorado.

Public Works appreciates the clear level of effort that was placed in the report, and the progress made since the June 7, 2007 submittal. 1. Public Works requires 3 sets of the construction drawings and 2 copies of the Final Drainage Report. 2. Please address all redline comments in the Final Drainage Report and in the construction drawings. 3. Please note, Per the review memorandum dated June 7, 2007, the applicant has proposed the construction of a pipe under WCR 55 and is required to submit an offsite improvements agreement to Weld County. Appropriate right-of-way permits must be approved prior to construction in the County ROW. 4. Per the review memorandum dated June 7, 2007, if Lot 4 stormwater runoff is proposed to be released un-detained, the Weld County Board of County Commissioners must approve a variance from current County Code 24-7-130 and Ordinance 2006-7. a. Per the review memorandum dated June 7, 2007, if a variance is requested and approved by the BOCC, the approved detention pond size and release rate for the proposed 29.7 acre subdivision shall be calculated from the 29.7 acres only. Future development on the 83.8 acre Lot 4 will require a separate detention facility. As noted in prior comments, the current detention pond and outlet structure for the 29.7 acre subdivision will be too small for future expansion on Lot 4. Future development of Lot 4 will require additional detention facilities on Lot 4. 5. Per the review memorandum dated June 7, 2007, please include a revegetation plan utilizing approved seed mixes published in the WCSDC Addendum. This plan is included in the erosion control Sheet 6 of 9, but is not discussed in the Final Drainage Report, as previously requested. 6. As stated in the review memorandum dated June 7, 2007, the design of proposed swale D4 is not erosionally stable and will result in repairs at the expense of the Homeowners' Association. Please refer to Table MD-2 in the USDCM (UD&FCD 2001), particularly in Major Drainage, Chapter 7, Sections 1.5.3, and 3.2.3, for possible solutions, and adjust the swale D4 design as requested from the June 7, 2007 review memorandum. 7. Please correct driveway culvert riprap sizing calculations for the proposed circular pipes. The December 2007 Final Drainage Report analysis utilizes methodology for rectangular pipes. 8. The headwater-to-depth (HW/D) ratio shall not exceed 1.50 in the 100-year storm event, per the Weld County Storm Drainage Criteria (WCSDC) Addendum, Page 37. Current design calculations show the HW/D ratio to be 1.93 for the 100-year storm. It may be necessary to increase the size of the culverts to maintain appropriate HW/D ratios. Recommendations Please provide corrected construction plans and text prior to recording the Final Plat. The applicant shall address the comments listed above during this Final Plan review process. Comments made during this stage of the review process may not be all-inclusive,as revised materials will have to be submitted and other concerns or issues will arise during further review. The review process will continue only when all appropriate elements have been submitted. Any issues of concern must be resolved with the Public Works Department prior to recording the Final Plat.

You also propose a cash contribution of $40,000 in this letter. I have spoken with Dave Bauer, Public Works, about your proposal. He has relayed to me that Public Works would in fact consider a lump sum non-refundable contribution for off-site impacts resulting from subdivision of the property. That amount totals $113,724 and is based primarily on the original calculations for the off-site impacts. I recommend that you contact Dave at 970-304-6496, extension 3739, to discuss any questions about the calculation or mechanism for payment. You should also contact Dave to determine how this off-site contribution should be reflected in the Improvements Agreement.
