Harbert, Pro-Tem Commissioner C. W. Kirby Commissioner Gordon E. Lacy Commissioner W. H. Webster Also present: Acting Clerk to the Board, Shelly Miller Assistant County Attorney, Lee Morrison Planning Department representative, Lanell Swanson The following business was transacted: I hereby certify that pursuant to a notice dated November 20, 1991, and duly published December 19, 1991, in The New News, a public hearing was conducted on January 8, 1992, to consider the revocation of Special Review Permit #908 issued to Laku Landing, c/o Philip G. and Ellen J. Yastrow/Randy Hocking. Said hearing of January 8, 1992, was continued to January 22, 1992, February 5, 1992, February 10, 1992, March 4, 1992, March 25, 1992, and again to May 6, 1992, at 10:00 a.m. At said hearing of May 6, 1992, Lee Morrison, Assistant County Attorney, made this a matter of record. Lanell Swanson, Planning Department representative, said staff recommends this matter be closed. She said the Flood Hazard Development Permit has been approved with the conditions that: 1) the applicants shall continue to pursue the floodway map revision through the Federal Emergency Management Agency (FEMA) ; and 2) any future use of any portion of the property shall comply with the most current floodway study available on the property and with all Weld County regulations. Ms. Swanson also said Lyle Zevenbergen, Resource Consultants and Engineers, Inc. , in a letter dated April 21, 1992, stated no violations any longer exist. Ken Lind, attorney representing Laku Landing, said the permit holders are in agreement with the conditional permit. He said the large stockpile on the south end of the property has been removed, as well as the stockpile of asphalt. Mr. Lind said there are two remaining stockpiles, structural fill and crusher fines, on the north end which have been reduced and are currently being removed and sold. He said all FEMA and Weld County regulations have been met, and he agrees with closing this matter. Tom Francis, surrounding property owner, asked if the letters which he submitted are part of the record. He stated concerns with the one-foot rise created by using the old map. The Board explained that the new lake will comply with the 1991 map. Mr. Francis asked if Lake #1 would also comply with the 1991 regulations. Ms. Swanson assured Mr. Francis that, pursuant to Mr. Zevenbergen's letter, the final proposed conditions for the site would not increase either flood or floodway elevations as long as the development is limited to the features described in the permit. Mr. Francis suggested the Board make a motion to the effect that when the project is completed, it comply with 1991 regulations. Ms. Swanson said that any work done since January 1, 1992, has conformed to current regulations. Mr. Morrison clarified that the final condition of Lake #1 and any new activities will comply with current regulations and suggested the permit holders be allowed an opportunity for rebuttal and/or agreement. He also informed Mr. Francis that his letters were received and are part of the record. There was no other public testimony offered. Mr. Lind said that the permit is conditionally approved on the basis that they comply with current regulations, and the 920400 CC- 4)J-- RE: HEARING CERTIFICATION - LAKU LANDING PAGE 2 permit holders are in full agreement with Mr. Zevenbergen's study. He agreed that all will comply with the 1991 regulations. Commissioner Lacy moved to accept staff's and Mr. Zevenbergen's recommendations, and agree that the project will be finalized according to the 1991 map. Commissioner Webster seconded the motion. Ms. Swanson suggested rather than stating the "1991 map", that the language "most current floodway study available" be used. Commissioners Lacy and Webster agreed to the change in the language, and the motion carried unanimously. This Certification was approved on the 13th day of May, 1992.

Using computer digitizing techniques, the drawings were prepared by Philip Yastrow from aerial photos obtained from the Weld County Treasurer's Office. The Property in question is located on Weld County Aerial Photo Number 0807-19,20,29,30. To the best of my knowledge, the drawings produced from this photo are accurate with respect to the aerial photogrammetric methods used at the time of photography. From the said aerial photo, I have verified the locations of existing geographical features such as the Cache La Poudre River, the Whitney Ditch, the B.H. Eaton Ditch and B.H. Eaton Ditch river return. Using the said aerial photo and sub maps 0807-20-1,0807-20-2 and 0807-20-4, I have verified the location of existing adjacent property lines to within the accuracy of the aerial photos and maps. A map obtained from Simons Li and Associates in Fort Collins was used to verify that with topographic contour intervals of five feet, the only contour line on the Property is at 4770 feet. Also from this map I have verified the location of the one foot floodway and the 100 year flood plain. The 100 year flood plain is slightly exaggerated on the Plot Plan to allow for ease of -graphical representation of the two home sites. At a time designated by the Weld County Department of Planning Services, I will perform this same certification on the l submitted mylar of the Use By Special Review Permit Plan Map.

Plot Plan Tree Farm Our primary agricultural plan calls for two small sized Christmas tree farms. Trees have a proven ability to grow on the Property in the low lying areas and with minor irrigation improvements, we feel large sections of the property can be dedicated to this use. Most of the soil for the tree farm will be provided from the topsoil from the lake areas. The trees will be planted and harvested on a cycle of about seven years. This cycle allows for a large number of substantially mature trees to always be on the Propertyand also allows us to perform the initial planting over a longer time frame. The trees will serve multiple purposes: •Economic benefit • Erosion control • Enhance scenery • Promote wildlife ^'t . :3. .10 �ac'e-a- Ma��- f` , kg 9a Laku Landing 3 - Application for Use By Special Review a a, . v • 3 o` X N• n b - o m a cur s U- U cc b5 � rA a — A I o a v r, 2. 4 m c u a -� E w "-' 0 3 n q a a s �n• `f m• t ; om ya o umo Viom : y J H a C LL V O O .+ O N 0 ,ri .. c O i° 0] m .n m O -O C a N O f E o s E - v a 2 0 o v z " ,_ o tA o .V :3 o a u e m Y a q 0c A a° L?

It is clear that individual stage is the issuance of a Flood Hazard decisions have not resulted in the wisest Boundary Map which indicates which use of flood plains. Flood damages have areas are likely to flood but does not been continually increasing and average show how high the flood will be. Later, annual damages are now estimated to FEMA conducts a Flood Insurance Study be in excess of 3.8 billion dollars. Much to determine the base flood elevations of this loss has been borne by the and, if appropriate,the floodway Nation's taxpayers through disaster relief boundaries.The base flood,often called programs,tax deductions for flood the 100-year flood,has a one percent losses,damages to public facilities that chance of being equalled or exceeded serve flood plain development,and the in any given year.The height of that flood costs of constructing flood control is called the base flood elevation.The projects to protect unwisely located land flooded by this size flood is in the structures.Additionally,local economic base flood plain. Over a 30-year disruptions and loss of life caused by mortgage there is a 26 percent chance flooding are losses which are (about 1 in 4)that this flood or a larger immeasurable. one will occur. The National Flood Insurance Program was created to reduce these losses by promoting a wiser use of flood plains.In return for making subsidized flood insurance available for existing structures,the participating community agrees to regulate new development in the flood plains. Structures which are built in accordance with the agreed-to regulations can also obtain very low cost flood insurance because of their reduced exposure to flood losses.The regulations are adopted by the community in a flood plain ordinance. The ordinance requires all new or substantially improved structures in the flood plain to be protected to a flood elevation determined either by the Federal Emergency Management Agency(FEMA)'or other sources. FEMA's elevations must be used if they are more restrictive. • 'FEMA was created by President Carter on April 1,1979.

Based on the new information, I have refined the construction conditions HEC2 hydraulic model. The existing stockpiles causeapproximatelya 0.2-lootmse in the 100-year water surface elevation at the development site and the next upstream cross section (approximately-one-half mile upstream). If the old floodway is the basis-for comparison,and the stockpiles are assumed tote outside-the delineation of the old floodway,then these stockpiles are not in violation of County regulations. If, however, one uses the new floodway as the basis for comparison, no additional rise in floodway elevations can occur. My-analysis indicates that thestockpilesalso cause an additional 02 foot-of rise-over the regulatory floodway, which is 1.2 feet over the base conditions. Therefore, construction conditions are in violation-of County and FEMA regulations for the 199211oodway. When I compared the aerial photograph with the contour map, I determined that the contour map does not show the correct locations-of some-of the stockpiles. This led me to make further comparisons and the discovery that half of one stockpile (thesouthem most stockpile at the bendway exit) is in-the old floodway. Therefore, strictly speaking, the development has always been in violation of the County regulation prohibiting stockpiles withinfloodways. I believe that the final proposed conditions for the site would not increase-eitherflood or floodway elevations, as long as the development is limited to the features described in the Flood Hazard Overlay District Development permit.

George Kennedy Chairman WELD COUNTY Weld County Commissioners P . U . Box 758 � Greeley , CO 80632 1992 t; it 16 N.'1 9: 35 CLERK Dear Mr . Kennedy . TO Tl iE BOARD I am writing this letter as I have not been allowed to present testimony at the hearings regarding the revocation of Laku Landings Use by Special Review (U . S . R . ) Permit: . This denial is the result of the insistartce by Laku Landings attorney , Mr . Lind , that public testimony not: be heard , even though I ant a neighboring land owner and am directly affected by the commissioners decisions . During the meeting in February of 1992 the board allowed the developers to apply for their Flood Hazard Development Permit (FHDP ) using the " 1980" map for the construction of their first. lake . The ramifications of this decision are that Laku Landing may cause a Wine foot riser in the flood waters by their stockpiling and burning activities . A one foot rise of the flood waters will subject an ADDITIONAL. one third of my farm to flooding . The neighboring land owners are not the people _in violation of Federal , State and Cutint.y regulations . however we are penalized . Laku Landing is in unquestionable violation and they are being rewarded . FFMA regulations regeire the developers to use the most current data regarding floodway location at the time of application for the Flood Hazard Development. Permit ( F11DP ) . Since the developer's just applied for their -'HDP in -February 1992 , they should have to abide by the 1991 regulations . Even if the regulations stated you used the most current dataat the lime of application for the CSR , which they do NOT . the developers were aware of the current. " 1.991 " location of the 100 year flood plain and the floodway as is evidenced by the Certification of Drawings by a:t Registered Engineer included in their Application for Use by Special Review dated March 11 , 1990 . ( see attatched copies ) I understand the dilemma the county is currently in . The developer has proceeded with construction without the proper permits and FFMA is reviewing Weld Counties practices in administering the flood insurance program . 1 understand by allowing th-e construction phase of lake #1 to proceed under the "1980" mappJng it eases financial constraints on the developer to remedy the Situation by marketing the stockpiles rather than relocating them to proper positions . l also understand the risk of my farm being flooded within the next 12 months is small . What I will not understand , nor do I believe FJMA w ' 1 I understand . is if any of the Laku Landing project in its FINAL STATE is allowed to exist in a condition which does not conform to the " 1991 " regulations . I also feel the current lake 41 pr•ojeet should be in this final " .'.991 " compliant state prior to ( he commenceneent of fur.`tlit'r activities . This is to iusurn the developers intent to act within the law and regulations imposed which has not been done in the past . Sincerely , rf� fThtrmas 0 .

Using computer digitizing techniques, the drawings-were prepared by Philip Yastrow from aerial photos obtained from the Weld County Treasurer's Office. The Property in question is located on Weld County Aerial Photo Number 0807-19,20,29,30. To the best of my knowledge, the drawings-produced from this photo arc accurate with respect to the aerial photogrammetric methods-used at the_time of photography. From the said aerial photo, I have verified the locations of existing geographical features such as the Cache_La Poudre River, the Whitney Ditch, the B.H. Eaton Ditch and_B.H. Eaton Ditch river return. Using the said aerial photo and sub maps 0807.20-1,0807-20-2 and 0807.20-4, I have verified the location of existing adjacent property lines to within the accuracy of the aerial photos and maps. A map obtained from Simons Li and Associates in Fort Collins was-used to verify that-with topographic contour intervals of five feet, the only contour line on the Property is at 4770 feet. Also from this-map I have verified the locationof theme foot floodway and the 100 year flood plain. The 100 year flood plain is slightly exaggerated on the Plot Plan to allow for ease of graphical representation of the two home sites. At a time designated by the Weld County Department of Planning Services, I will perform this same certification on the submitted mylar of the Use By Special Review Permit Plan Map.

As yon may recall,this was the revision requested based on the error in the current Flood Insurance Study. There are three pieces o-f information we now need to make the application complete. The first item needed from the County isa letter to FEMA (but sent to Baker engineers) stating you are aware of the request for a floodway revision. The next item is a copy of a public notice informing the community of the floodway revision. I would assume this would be similar to any other public notice we have done in the past, which we would pay for. It might say something like "...There is spending request for a revision of the floodway in the North Half of Section 29 and the South half of Section 20,Township-6 North, Range 67 West of the 6th P.M., in both the Town of Windsor and the County of Weld..." The only other item we need is a similar letter from the Colorado Water Conservation Board stating they are also aware of the request. After talking with Bryan Hyde, he would like a request from your office to write the letter,instead of directly from me. Please address the FEMA correspondence to: Federal Emergency Management Agency c/o Michelle C.

(RCE) has reviewed the Flood Hazard Overlay District Development Permit for the,roposed Laku Landing development. -Thereviewaddresses 1) interpretation of regulations pertaining to development in a floodway and the appropriate procedures required to meet these regulations,2) review of proposed final conditions hydraulic analysis (HEC-2)and 3) review of the construction conditions HEC2 analysis. Development With a Flooding Boundary As shown in Attachment 1,-encroachment in the floodway fringe-can result in a rise in the water surface. When-development-occurs within the floodway, noaddfional rise is allowed. Therefore,the water surfaces which should be compared are-those generated from pre-and postAevelopmentanalyses, each encroachedhqually.?-his procedure ensures-that_development within the-floodway would not produce any incremental increase in water-surface slevations beyond thoseoccurring after potential idevelopment outside the floodway. Final Conditions The only differences between theTegulatory HEC-2 analysis and the proposed final conditions HEC-2 analysis are a reduction in Manning's n-at the development site and the elevated spectator area. The reduction in Manning's n compensates for-thereduction in cross sectional area caused by the fill required for the spectator area. Theproc-edure_used for calculating the reduction in Manning's n is appropriate and the calculations were confirmed. We conclude that under final conditions no rise would be expected foreither encroached or_unencroached conditions. Construction Conditions For the existing construction conditions, the permitapplication indicates that no rise would occur for unencroached conditions. However, if one compares the water surfaces for equally encroached conditions (Floodway) a 0.2 foot rise occurs at cross section 147200. -This rise is in-violation of regulations. Four problems exist with the HEC2 analysis of construction conditions. These problems include inappropriate placement of the additional cross sections and incorrect analysis-techniques. 3665 JFKParkway, Building 2, Suite-300 • P.O. Box Q • Fort Collins, CO 80522 (303) 223-5556 • Denver Metro (303)372-1806 • FAX (303)223-557-8 Fort Collins, CO • Davis,LA • Laramie, WY Mr. Chuck Cunliffe Weld County March 23, 1992 Page Two The first problem is that the additional cross sections do not fully depict the blockage produced by the-gravel stockpiles. This is especially true of the upstream most stockpile which extends approximately 800 feet across the flow path. The second problem is that the additional cross sectionsare not-encroached to-represent a floodway-condition. This is required to compare floodway conditions. The third problem is that the effects of fill is placed in a flow pathexist upstream and downstream of the-ill. The additional cross sections used in the construction conditions deck-should have additional blockage within the 'flood shadows" of the stock piles. Attachment 2-shows the flood shadows resulting fromtheatockpiles. These flood shadowsare basedon a 1:1 contraction ratio and a 4:1 expansion-ratio as-recommended by the HEC- 2 manual. Theareas within the flood shadows should be considered ineffective during a HEC-2 analysis. The fourth problem is that it appears that the additional cross sections-were surveyed to the lake waters edge. As shown in-Attachment 3,1 is-pore appropriate to survey to the top tank of the lake, thereby excluding the cross sectional area of the lake. When the third and fourth problems are rectified, ao.5' rise is expected at Cross Section 139690 and a-O.1' rise is-expected at crosssection 147200. Conclusions While the-final conditions HEC-2 analysis indicates that the Laku landing development would not increase water surface elevations at -or upstream of the development, it appears that the construction conditions are in violation of-floodway regulations. It is-ouropinion that the stock piles should be removed as soon aspossible. Further analysis is-required to determine the full impact of the-constructiontonditions. This-analysis could be used to determine the necessary amountofatockpile removal and/or replacement. Sincerely, RESOURCE CONSULTANTS A ENGINEERS, INC. Lyle W.

The use is Located in a flood -hazard area which has been defined by the administrator of the Flood Insurance Program for Weld County (Department of Planning Service of Weld County) as a flood hazard overlay district. _Our client' s project was approved by Weld County officials on May 23 , 11990; Phase 1 of the project was commenced during May -of 1991 and finished prior to September of 1991; and our clients applied for a Flood Hazard Overlay District Development Permit on August -8 , 1991 when their use was determined to require such a permit due to the need for a building permit. This August 8 , 1991 Flood -Hazard _Overlay District Development Permit was rejected by the Weld County Planning Department primarily on the basis that Weld County had been provided (from FEMA) some preliminary data which would change the zoning classification of the property being developed from Flood Trone to Floodway. Under the Flood-Prone -zoning then in existence the _project was permissible, but under the Floodway district zoning, the project as previously approved by Meld County would no longer be permissible. Our clients were informed that the regional TEMA office had instructed Weld County to use the preliminary data rather than the Official Weld County Flood Hazard Overlay District Zoning Map which was then in existence and upon which our clients detrimentally relied. Unfortunately, Phase 1 of the project was basically completed at the time the -Flood Hazard Overlay District Permit was applied for and the plans could not then 3be changed. For your convenience I am including a portion of the Meld County Zoning Ordinance relating to the Flood Hazard Overlay District, which I might add, had been approved by the regional -FEMA office. Specifically, I refer you to Section 53 . 4 . 1 -which clearly defines the Official Meld County Flood Hazard Overlay District l 4 Ms. Brenda Coranslo Office of General Counsel February 14 , 1992 Page 2 Zoning Map which was in existence when our client ' s project was approved and when our client ' s Phase 1 project was completed. Nowhere in the Weld County Zoning Resolution is there any kind of statement that this Official Weld County Flood Hazard Overlay District Zoning Map can be changed by some "verbal" order from the regional FEMA office nor does it instruct the permit holder to ignore the Official Weld County Flood Hazard Overlay District Zoning Map. In f-act -and in truth, the applicant is required to comply with said official zoning map. I would advise you that FEMA did approve a revised floodway map which became effective on September 27 , 19191 . This new map was then adopted by Weld County on _January 21, 1992 as the Official Weld County Flood Hazard Overlay District Zoning Map. The regional FEMA office has informed Weld County that they may be in violation of certain FEMA regulations as well as the Flood -Insurance Program for not "complying with" Weld County ' s Zoning Resolution. Clearly, Weld County, as well as my clients , did follow the Weld County Zoning Resolution by using and relying upon the Official Weld County Flood Hazard Overlay District Zoning Map which was in effect when the August 8 , 1991 permit was applied for and when the Phase 1 project was being completed. As this -curious legal interpretation by the regional FEMA office has now placed both Weld County and my client' s project in jeopardy it is necessary that we have some determination that Weld County and my -clients were correct in following the weld County Zoning Ordinance which makes specific reference to the Official Weld County Flood Hazard Overlay District Zoning Map in effect during the summer of 1991 . It would be our opinion that the earliest date that the County should have changed the Zoning Ordinance or "interpretation" of the Zoning Ordinance would have been September 27 , 1991, being the final effective date of the new map. It would -be our request that we receive an opinion from you indicating that as the Weld County Zoning Ordinance referred to the official map that was in existence during the summer of 1991 (prior to the revision effective on September 27 , 1991) that this was the proper procedure and the floodway utilized by my clients during the summer of 1991 was based upon the official -nap that was then in existence. I should add that I do not argue nor dispute the fact that subsequent to September 27 , 1991 any further development upon the project will have to be in accordance with final effective new floodway map dated September 27, 19191. However, to attempt to retroactively apply a zoning map or floodway map not part of the r Ms. Brenda Coranslo Office of General Counsel February 14 , 1-992 Page 3 zoning _ordinance is not in accord with generally accepted legal principles and is clearly not in accordance with the FEMA approved Weld County Zoning Resolution.

Swanson, Current Pla;xnsi,o .v ,tLL COLORADO From Laku Landing Flood Hazard Development Permit subject: As we have discussed, there are four possible scenarios regarding additional requirements for the -Laku Landing Flood Hazard-Development Permit application. The four scenarios are: A) Review the application pursuant to the recorded Floodway map, effective -April 22, 1980. B) -Review the application pursuant to the Floodway and Floodprone districts as shown on the USR plat recorded January 30, 1991. L) -Review the application pursuant to the most current study, which was actually recorded by the county on January 21, 1992. The RENA map was effective on September 27, 11991. D) Review the application pursuant to a revised Floodway map. If the application is reviewed pursuant to Scenario A, the following information is still required: The map as submitted must be revised to show the 1980 Floodway and Floodprone boundaries. The Floodway area must be maintained as required by Section -53.6 af the Weld County Zoning Ordinance, specifically: No encroachments shall be permitted unless certification is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of an intermediate regional flood; and, the area within the Floodway may not be used for the storage of flammable or explosive materials, sand and gravel and other mineral deposits, fill material, and materials that, in times of flooding, are buoyant. Certification provided must be supported with detailed engineering data to support the conclusion stated in the certification. Certification has also not been provided showing that the use -will not cause any increase in floodwater levels during an Intermediate Regional Flood and will not limit or restrict the flow capacity of the #loodway. The application as submitted addresses the proposed use AT COMPLETION. The applicants must address these requirements for existing conditions during construction and -mining activities. The area shown in the 1980 scenario as being in the Floodprone districts must conform to Section 53.7 of the Weld County Zoning Ordinance. If the dwelling units are to be covered on this submittal, exact elevations must be provided, both of the Intermediate -Regional :Flood and the lowest floor of the proposed structures. FEMA map numbers must be provided showing the source of information. If another source of information is used, specific information-must be provided regarding that study. The Floodprone area is the only location where sand and gravel could be placed or stored. Each structure or use to be on the property must be addressed pursuant to Sections 26.4, 53.6 and 53.7 of the Weld County Zoning Ordinance. Er ) 11LJ / -1- '7 � I Laku Landing Flood Hazard Development Permit February 11, 1992 Page 2 A registered professional engineer must certify that the water and sewer systems are designed to prevent inundation or infiltration of floodwater into the system or to prevent discharges from the systems into the floodwater of an intermediate regional flood. Scenarios B (the Flood Hazard Overlay District as shown on the recorded USR plat) and C (the Flood Hazard Overlay District as revised by FEMA on September 27, 1991, and adopted by the County on January 21, 1992) , appear to be the same. Under these scenarios, most of the property is in the Floodway. A very small portion of the property is in the Floodprone Districts -- basically, the area to the south of the -property where the homesites are proposed. Under these scenarios, most of the property would be subject to Section 53.6 of the Veld County Zoning Ordinance, as swell as the standards set forth in Section 26.4. Again, any proposed use or structure in the Floodway requires rertific-ation by a registered professional engineer that the proposed use or structure, when built, will not cause any increase in floodwater levels during an Intermediate -Regional Flood. No encroachments, including fill, new construction, substantial improvements, and other development mouldbe permitted unless certification is provided by a registered professional engineer demonstrating that encroachments shall not result in any increase inflood levels during the occurrence of an Intermediate Regional Flood. None of the property in the Floodway could be used for the storage or placement of sand and gravel or any other mineral deposits or fill material. Certification would still be-needed addressing the uses on the property during the construction phases, and not just after the project is completed. All structures in the Floodway area must be certified to meet the standards of Section 33.6 of the Weld County Zoning Ordinance. It there are to be any water or sewer systems in the Floodway, certifications must be provided regarding infiltration and inundation. The standards of Section 53.7 must be certified for the small area which is in the Floodprone Districts, under Scenarios B and C. Again, all structures and water and sewer systems must be addressed pursuant to the requirements of Section 26.4 and 53.7 of the Weld County Zoning Ordinance. The application and certifications must address not only the conditions at completion of the project, but also the uses occurring on the property during the mining and construction activities. If the application is to be reviewed pursuant to ar-evisedYloodway map, Scenario D, the first step is the applicants' in that they must apply for a map revision with FEMA. If the applicants receive the approval of the FEMA administrator, the County may adopt the revised map. This scenario will take at least 60-90 days for -FEMA review, after a complete application is submitted to them and accepted. If a revised map is adopted, the Weld County Zoning Ordinance Sections 14.6, -53.6, and 33.7 would apply as in the other scenarios. pc: Lee Morrison, Assistant County Attorney Ken Lind, Attorney at Law Laku Landing OCT 1 7 1991 World Class Water Ski Site Cec:ty°i ne.3 -Phil Yastrow Randy Hocking (303)229-4544 (303) 353-3750 P.O. Box 332 Windsor, CO 80550 October 16, 1991 Lanell Swanson Weld County Department of Planning Services 915 10th Street Greeley, Colorado 80631 Dear Lanell: The two enclosed documents are being submitted in accordance with The Weld County Zoning Ordinance Flood Hazard Overlay District regulations. The first document is the Flood Hazard Development Permit application supplemental information, amended to reflect the changes made since our last submittal. Please consider this with the pre-printed application and certification form we submitted in August. The second document entitled "HEC-2 Study of Laku landing" contains detailed engineering data which will help explain and document the methods of calculation used in producing this permit application. Also, the enclosed computer diskette contains all of the simulation input and output used by the HEC-2 water surface profiles program. As discussed with Mr. Cunliffe, Planning Staff should review this permit for completeness before _I submit it for final certification by my engineer. Sincerely, L,9 } 4, Phil Yastrow h;hi f 4 FLOOD HAZARD DEVELOPMENT PERMIT III - 1 � OCT 1 7 1991 I FLOOD HAZARD DEVELOPME `t'EyRMIT This proposal is submitted pursuant to our Use By Special Review Permit (USR #908), the purposeof which is gravel mining, processing and reclamation for a recreational facility (ski lakes) in the agriculturalzone district. The purpose of this document is to demonstrate that the proposed building sites and structures are safe from flooding and that the proposal complies with the Weld County Zoning Ordinance. The textual portion of this permit explains how the standards of §53.6 of the Weld County Zoning Ordinance have been orwill be met. Upon completion of the construction phase of our project, there will be no rise in the water levels present during an intermediate regional flood. This Flood Hazard Development Permit application will reference detailed engineering data to support this, as well as describe the methods being used to minimize flood damage should an intermediate regional flood occur before the allowed construction completion date dictated by our Use By Special Review resolution. The data contained in-this permit application will be sufficient to process this permit from a regulatory viewpoint. There is, however, a considerable amount of information contained in the related document entitled "HEC2 Study of LakuLanding", that would be redundant if contained here. Therefore, it is appropriate to include both documents under the same cover. HOMESITE AREA As shown on the attached Flood-Hazard Development Permit Map, approximately 13 acres of land we own outsideof the floodway has been designated for potential homesites.This area includes land located in FP-1 and FP-2 Floodprone Districts and will be elevated using a combination of sand,gravel and topsoil in order to_protect the homesites from flooding. Based on the results of an existing condition floodway study performed by Simons_ i & Associates of Ft. Collins, it has been shown that with suitable vegetation, erosion will not occur significantly in the developed areas of our property, including the elevated homesite area outside of-the floodway. The ground elevation and lowest floor of the homes will equal or exceed the regulatoryflood datum of one foot above the water surface elevation of an intermediate regional flood. The elevations applicable to each homesite will be certified by a licensed surveyor or registered engineer prior to the construction of that structure or dwelling. To further describe the topography of any potential homesite, figure 1 shows the cross section of the FEMA Flood Insurance_Study (FIS) which intersects Laku Landing. The proposed homesite area is located to the south of section 'AA'. Because it is unclear exactly where the dwellings tobexonstructed in the future willbe located, the profile shown in figure shows the extremes necessary for any homesite to be in compliance with §53 of the Weld County Zoning Ordinance. Any dwelling_permitted and constructed in the potential homesite area will be built at a level no less than the regulatory-flood datum with-methods in accordance with §53 of the Weld County Zoning Ordinance andanyapplicable regulations of the Weld County Building Ordinance.

FLOOD HAZARD DEVELOPMENT PERMIT 3 DOMESTIC WATER SUPPLY -Prior to construction of each domestic water system a registered engineer will certify that any such domestic water well and water supply, treatment or storage system is designed to prevent inundation or infiltration of floodwater into such system during an intermediate regional flood. It is our intent to have Empire Labs of Fort Collins certify this at the time of any structure or dwelling's utility system design. SEWER SYSTEMS Prior to construction of each sewer system a registered engineer will certify that such sewage treatment system and individual sewage disposal system is designed to prevent inundation or in- filtration of floodwater into such system and to prevent discharges of the sewage system into the floodwater of an intermediate regional food. It is our intent to have Empire Labs of Fort Collins certify this at the time of any structure or dwelling's utility system design. LAKE IMPROVEMENTS lake Surface All aspects of the lake surface which may affect-the levels of an intermediate regional flood are addressed in the_document "HEC-2 Study of Laku Landing". By the allowed construction comple- tion and material removal date of August 1996, there will be no rise in water surface elevations as aresult of any floodway development.Turing the construction and material removal phase, which is now two years ahead of schedule, flood damage potential will be minimized using many available techniques. These techniques will address water surface elevations as well as sediment transport (erosion). For more information on these techniques, see `CONSTRUCTION PHASE',Tage 4. Judges Towers Minor improvements such as judges towers required for tournament water skiing activities will be built on wood columns that will be anchored asufficient depth into the ground to prevent flotation, collapse or lateral movement of the towers by the hydrodynamic forces of$ooding. All platforms attached to the towers will be elevated above the regulatory flood datum to avoid alteration of the water course. The exact det-ails of construction of the judges towers are not known at this time. To satisfy the curiosity of anyone interested, the judges towers are solely-for the elevated seating of at most two judges on a tower. Figure 3 illustrates conceptually what a tower will look like.

This drawing is not to be considered the actual design, but it is important to note that the tower is extremely simple in design and function. At the time any judges tower is erected, the complete and detailed design will be submitted for approval in accordance with any regulation in the Weld County Building Ordinance. CONSTRUCTION PHASE Because of the lack of non floodway area on our property, mining and processing activities are occurring within the floodway. For thirreason, it is important that we consider methods of flood damage minimization in case an intermediate regional flood were to occur while there are stockpiles on the property. The document "HEC-2 Study of Laku Landing" explores these methods from a scientific perspective, but the general methods are also discussed here. Water Level Minimization All stockpiles now on the property have been analyzed using HEC-2. The placement of material is now being done and will-continue to be done in such a way as two fall into one of the two stockpile _regions shown in figure 4. By placing the material in piles which are-parallel to the direction of water flow, the net effect is much less than perpendicular or-even ranclom placement would cause. The maximum rise in the water surface of a 100 year flood, as calculated by HEC-2 assuming zero conveyance or infinite blockage in the regions shown, is 0.2 feet. Wherefore,-as long as-material is placed in these regions, the rise would never be greater than 2.4 inches. Sediment Transport Minimization Perhaps more important than water level changes is the possibility of any material stockpiled %r ',,- FLOOD HAZARD DEVELOPMENT PERMIT : N ,,,' - Cache la Poudre River d / 1 water�base flood -' 145760 _stockpile regions x 136450 a EO CO &0 ® 1® I I I I I I I III ;x— PnS-aoss sections SCALE(feet) 139690 Figure 4. Stockpile Regions on the propertytheing swept away by flood waters. For this reason,any-material stockpiled an the property in either of the stockpile regionswill beprotected by sandbags filled with sand and gravel 3/8 inch and under. This is the predominate type of material which is a by-product of producing material to the specifications of the Colorado Department of Highways. The sandbagswill protect the stockpiles and the height of the sandbag wall will be at least the height-of the intermediate regional flood water levels. Upon construction of the sandbag wall, certification as to its height will be submitted to Weld County. Stockpile Disposition As a result of creating material under the rigid specifications of the Colorado Department of Highways, there is an excess of 3/8 inch and under material which will not be needed for the highway project or shoreline reclamation. There is a market for this material, but-lot an immediate teed for all of it. In addition there is a much smaller amount of crushed rock remaining because the proportions of types of material actually used on the State project are different than the proportions which occurnaturally on the property. As previously stated, all stockpiles will be placed within either of the two stockpile regions.

Current Stockpile Locations The anticipated schedule for stockpile removal as well as excavation of the second lake is very much dependent on the gravel market. As we have already shown,the fact that our material is being given away greatly increases the demand as well as expedites the speed at which it is removed. Connell Resources is confident of their ability to market the material currently stockpiled based on upcoming bid advertisements. Connell feels that the market for our material will be strong enough to strip the topsoil and begin dewatering-activities on the second lake this winter. As agreed upon by Connell Resources, all stockpiling within the floodway will now fall into one of the two designated stockpile regions, with all material to be removed before the completion date designated by our USR Resolution.

Laku Landing Site Map was made available for public purchase September 26,1991 has a vastly enlarged floodway and has an upstream extent which is greater by more than one mile. 1.2 Purpose Because much of Laku Landing is located in the floodway district of Weld County,there is concern that the lake surface roughness may adversely affect the water surface profile during a flood. The purpose of this document is to show that the proposed floodway development, when built, will not result in any increase in the flood levels during the-occurrence of an intermediate regional flood and that during construction, the effect will be minimal. Throughout this document, the terms "base flood discharge", "intermediate regional flood", and "100 year flood" will be used interchangeably. o, n ,:, • Existing Floodway Study 3 1.3 Scope of Study The different sections of this document discuss: (a) the existing floodway study performed by Simons Li & Associates, with modifications made by Baker Engineers, (b) the technical aspects, both hydrological and topographical of the Laku Landing Development, (c) hydraulic analyses of the proposed conditions, and (d) hydraulic analysis of construction conditions. It has already been determined by FEMA, that no new cross sections need to be added, and no new field surveys-need to be taken for this study. Instead, we will analyze the Laku Landing Development using the same methods that would have been used if Laku Landing existed in its final form before the most recent Flood Insurance Study (FIS). Because of this, all modifications to the existing FIS IIEC-2 data, will be related to the cross section which intersects-the lake area of Laku Landing. This is cross section #139690, and will be the focus of considerable-attention throughout this document. 2. Existing Floodway Study An interesting point concerning the current FIS study, is that for a portion of the river surround- ing Laku Landing, there is no overbank area and therefore, the entire cross section #139690 is considered part of the river channel. For this reason, a single value for Manning's 'n' roughness coefficient is used to_describe the entire cross section. In the case of crosssection #139690, an 'n' value of-0.062 was used, producing a 100 year flood water level of 4769.9 feet. Figure 3 depicts cross section #139690 in the existing FIS study.

Current FIS Study of Existing Conditions Hydraulic Analysis of Proposed Conditions 4 The method used in computing values of Manning's 'n' for the current FIS, according to Scott Queen of Simons ILi & Associates, was to compute the total surface area from the cross section in iquestion-halfway downstream to the-previous cross section -and halfway upstream to the next cross section. Oncethis total surface area was found, the different areas of land that had different roughness characteristics were weighted using the percentage their area wasnfthe total area. This weighting technique was used to achieve a single 'n' value for each channel or overbank -area, eliminating the need for horizontal descriptions of Manning's 'n' using the NH card. 3. Hydraulic Analysis of Proposed Conditions The motivation for performing this study is due to the fact that two lakes are being created in the floodway. During an intermediate regional flood, the lakes will fill completely with water, and then -the flood waters will continue downstream, except that now the flow will be over the water in the lakes instead of the ground which used to occupy the lakes, and water-has a roughness considerably less than that of ground. -For existing ponds within the-scope of the current FIS study,Simons Li & Associates used a Manning's 'n' roughness value of 1102. Figure 4 can be used to determine the area halfway to the upstream and downstream cross sections which we will call the cross sectional related area. The-total surface area of the lakes at LakulLanding is 34 acres, and the total cross section related horizontal surface area is 119 acres. The computer program used to create-these drawings is also capable of calculating-the area of polygons using triangular decomposition. In computing the new area weighted roughness for cross section #139690 it is important to realize that the portion of land that the lakes will occupy has a roughness very close to the total computed existing roughness of-0.062. Before we purchased the land, for several years there has been considerable weed growth occupying the lake area. "Open Channel Hydraulics" by Ven Te Chow (page 113), gives a roughness of 0.05 to 0.07 for scattered brush and heavy weeds in flood plains. This means that the area weighted roughness approach will be reasonably accurate. In computing the new roughness for cross section #139690, we have 0.02 x 34 + 0.062 x (119- 34) i Ob50 n = 119 This section will utilize the HEC-2 water surface profile program to analyze the proposed con- ditions at Laku Landing. First,a simulation will be run showing the drop in water surfaces and increase in flow velocities caused by the presenceofthe lakes during the occurrence of a base flood discharge. Then, a method of-topography change will be introduced which will return-the water surface levels to their original levels which existed at-the time of the current FIS study.

Areas Used In Roughness Calculations 3.1 Flood level Analysis Due To Reduced Roughness As previously stated, the construction of two lakes at Laku Landing since the current FIS will reduce the roughness associated with cross-section #139690. The existing roughness coefficient of 0.062wil1ibe replaced with 0.050, based on the-calculation in the previous section. Referring to the HEC-2 results of the Baker Engineers study see chapter 7 `Existing Conditions Simulation Output', page 15, the only two changes made to this data are the_following: 77178 > NC .050 89c90 C MC 0.055 0.055 > 8C 0.055 0.055 0.062 The above-nomenclature describes the differences to the two files. The first difference is that there is a new line #78 which is NC .050 Hydraulic Analysis of Proposed Conditions 6 The next-difference is a change to the old line #89 (now_line #90 because of the above inserted line) which now reads IC 0.055 0.055 0.062 An arrow at the beginning of a line which points to the left refers to the original file, and a right pointing arrow refers to the changed file. The first of the above changes reflect a new value for Manning's 'n' (for the channel) at cross section #139690 of 0.05. Remember, there is no overbank area for this cross section. The second change resets the channel roughness back to a value of 0.062. A summary of the simulation results is shown in table 1 (for more detailed information, see chapter 9 `Modified Roughness Simulation Output', page 27).

Because of the abundance of Nunn Clay Loam and gravelly-substratum,lthe spectator area will be resistant to-the hydrodynamic forces of flooding, while capable of goorl root penetration from the grass to be grown on it. The type of grass to beplanted on the spectator area has been chosen based on the recommen- dations in "Open Channel Hydraulics" by Ven Te Chow (page 185).Because the soil is ainixture of clay loam and fine gravel, this is considered a fairly erosion resistant soil, so by planting buffalo grass or bluegrass on the spectator area, there will be no erosion at flood water velocities less than five feet per second. Based on the data in table 2, the proposed flow velocity at cross-section #139690 will'be only 3.4 feet per second. The maintenance of the grass is important to consider. All grass surrounding the lake areas, including the spectator area will be maintained with regular mowings to a length not to exceed four inches. In addition, we own an adjudicated well which will be the source of all landscape irrigation water to be used in our underground sprinkler system. 4. Hydraulic Analysis of Construction Conditions During the construction-phase of our project,temporary stockpiles will be located in the floodway. This section will address thesestockpiles, and the methods being used to minimize their effect will be discussed. Although there would be a slight increase in the water levels present during a base flood discharge, the methods of minimization employed make this rise almost imperceptible. The -proposed locations of stockpiles will first be discussed, and then an analysis using the HEC-2 model of the floodway will be given. 4.1 Stockpile Locations At this time, all stockpiles fall into two general location categories: those near the North quarter of the lake area, and-those nearthe South quarter.Figured shows these two generalareas, an-d the effective "sh-allow" area created by any blockage within either area. Theshadow area is essentially a_corridor_parallel with the direction of water flow during a base flood discharge, and perpendicular to the cross section which intersects the lake area. 4.2 Stockpile Sediment Transport In-the event of an intermediate regional flood, it is importantto prevent any stockpiles present on 1 Soil Survey of Weld County, Colorado, Southern Part performed and compiled by the U.S. Department of Agriculture Soil Conser- vation Service in cooperation with the Colorado Agricultural Experiment Station. w " =Y 1 . .A Hydraulic Analysis of Construction Conditions 10 S.

Sediment transport modeling is beyond the scope of this report, so it is important to ensure that it does not happen. Any stockpiles remaining on the property between April 15 and August 1 of any year will be treated to eliminate the possibility of sediment transport. This will be done with a solid wall of sandbags filled with sand and small rocks measuring 3/8 inch in diameter and smaller. The height of the sandbag wall will be at least as high as the water level present during a base flood discharge, and this height will be certified by a licensed surveyor. 4.3 HEC-2 Simulation Analysis Using the same HEC-2 model used for the modified roughness and spectator area simulations, further topographic changes were made to represent the North stockpile region. The simulation results derived from the temporary conditions are summarized in table 3.

Temporary Construction Conditions 5. Summary of Results This report has shown that any $oodway development atlaku Landing will-result in-no rise in the water levels of an intermediate-regional flood. In addition, a method of Treating no_change in the water levels was proposed which is in accordance with all federal and local regulations. The hydraulic analyses of this report-started off with a brief introduction to the existing -FIS data and how laku Landing and surrounding properties were modeled by-Simons Li & Associates and Baker Engineers. The cross section which intersects the proposed lake area (#139690) was Summary of Results 12 then examined for existing conditions, and a new roughness coefficient was calculated based on the roughness of theproposed water surface in comparison with that of the existing ground. A simulation was then run on the FIS data with the only change being the newly computed roughness of the single cross section intersecting the lake area at Laku Landing. The result of this -simulation showed a water surface drop of 0.1 feet at cross section #139690 and #147200, which is two cross sections upstream from Laku Landing. The channel velocity increase at these two cross -sections is 0.2 and 0.1 feet per second, respectively. Then, -a-raised spectator area located approximately halfway on the longitudinal axis between the two lakes was proposed. This spectator area was simulated with the results showing no change, rise or fall, in the water levels present in a 100 year flood. The only increase in'channel velocity occurs at-cross section #139690. This is an increase of 0.7 feet per second, yielding a total flow rate of 3.4 feet per second. Using the velocity results, erosion was addressed to insure the integrity of the spectator area. Finally, the temporary conditions which will exist during the construction phase of our project were addressed. The net effect of the two stockpile locations was shown to be 0.1 feet at both cross section #139690 and 0.2 feet at cross section 4145760. At cross section 4139690, the channel velocity increased 1.9 feet per second to 4.6 feet per second, and at cross section #145760, the channel velocity decreased 0.1 feet per second to1.TJ feet persecond.

The textual portion-of this permit explains how the standards of section 26A of the Weld County Zoning Ordinance,described on page three of the_permit application, have been or will be met. POTENTIAL TIOMESITE AREA As shown on the attached Flood Hazard Development Permit M-ap, approximately 13 acres of land we own outside of the floodway has been designated for potential homesites. This area includes land located in F-P-1 and FP-2 Floodprone Districts -and will be elevated using a combination of sand,gravel and topsoil in order to protect the homesites from-potential flooding. Based on the results of an existing condition Iloodway study performed by Simons Li&Associates of Ft. Collins, ithas been shown that with suitable vegetation, erosion will not occur significantly in the developed areas of our property, including-the elevated homesite area outside of the floodway. The ground elevation and lowest floor of the homes will equal or exceed the regulatory flood datum of one-foot above the water surface elevation of an intermediate regional flood. The elevations applicable to each-homesite will be certified by a licensed surveyor or-registered engineerprior to the construction of that structure or dwelling. It is our intent that the homesite area described in this application will cover the two homesites included in the previously approved-USR-908as well as any additional homesites to be permitted in the future that may'be constructed within the 13 acres outside of the floodway. In other words, any dwelling which is ever constructed on the property will meet the flood hazard requirements outlined in this permit. DOMESTIC WATER SUPPLY Prior to construction of each domestic water system a registered engineer will certify that any such domestic water well and water supply,treatment or storage system is designed to prevent inundation or infiltration of-floodwater into such system during an intermediate regional flood. FLOOD HAZARD DEVELOPMENT PERMIT 2 It is our intent to have Empire Labs of Fort Collins certify this at the time of any structure or dwelling's utility system design. SEWER SYSTEMS Prior to construction of each sewer system a registered engineer will certify that such sewage treatment system and individual sewage disposal system is designed to prevent inundation or in- filtration of floodwater into such system and to prevent discharges of the sewage system into the floodwater of an intermediate regional flood. It is our intent to have Empire Labs of Fort Collins certify this at the time of any structure or dwelling's utility system design. LAKE IMPROVEMENTS Minor improvements such as judges towers required for tournament water skiing activities will utilize II piling, telephone poles or similar-type materials-that will be anchored a sufficient depth into the ground to prevent flotation, collapse or lateral movement of the towers by-the hydrodynamic forces of flooding. All platforms attached to the towers will be elevated above the regulatory flood datum to avoid alteration of the water course. The lakes themselves will not cause any rise in the levels of the intermediate regional flood because during a flood, the lakes will fill to capacity,and water will flow past unobstructed. The designedsurface dimensions of the lakes are shown in figure 1,and our reclamation plan indicates that all topographic features outside of the lake area in the floodway will be unchanged. See `CONSTRUCTION PHASE', page 3, for methods we-are using to achieve this. There is the possibility of slight decrease in the water level during an intermediate regional flood, due to the roughness of the lakes' water surface being less than that of earth with stones and moderate vegetation. For this purpose we will conduct a study using the JIEC-2 modeling system, and modification of the single flood insurance study cross section that intersects the East lake. This study is being performed by Tuttle-Applegate. The results of the-study will be available to Weld County after being reviewed by FEMA. The-engineer's certification of complience with Weld County Regulationssequiring-no rise in the flood waters of an intermediatesegional flood is attached.

Lake Surface Dimensions CONSTRUCTION PHASE The construction phase of the project will utilize methods and practices that minimize potential flood damage. These are: • Transfer points of excavated material in process will be minimized from May 1 through June 15 of each year when the risk of flooding is at its peak. Co' n 'n FLOOD HAZARD DEVELOPMENT PERMIT 4 • All aggregate material which in process is already designated for a project, and will not remain on site longer than it takes to complete processing and realistically load and transport it. • Consultation with the Poudre River Commissioner, Shawn Hoff, as to the historical dates of flooding in order to minimize our liability exposure. • Consultation with John Lion and Doug Gore of FEMA to have the benefit of professional opinions relative to flood risk and methods to minimize the impacts of potential flooding. • Unsold topsoil, sand and inferior aggregate is positioned to be pushed back into the ponds once the raw aggregate is removed from the lake bottom for processing. • Material transfer points will be built as high as possible in order to block less water should there be an intermediate regional flood. As shown in the accompanying aerial photo of the Special Review area, topsoil is being placed directly adjacent to the lake edge. This material will be pushed into the lake bottom, once all of the aggregate material is removed from the lake bottom in any given 1000 foot stretch of lake. The design of the gradually sloped shorelines to be constructed using the topsoil and rejected aggregate is shown in figure 2. existing ground level It Si 4 proposed water level r•r.r•r•r•r�r•r y1.1.1.1.1.1.4••.t r.r•r•r•r•r•r•r � rye. . .'.4.4.b4.4.4.4.' r•r•J•r•r•r.r•J .t �., c; ,a4 5w5 r.r.r•r.ry.r•r r +.fT,' , 4.4.4.4.4.4.4.4.• '* t r.r.r.r.r.r.r.r.r r v` r•r•r•r•r' •r•r "' ti.4.1.4 A # 1; ' i 'Y (t0 hatto r•r•r• r•r•nr7 v,, 4.4.4• 4.4.1'4.• d .r.r.r i.r•r•r•r. .

Typical Lake Cross Section In addition, the aerial photo shows all areas used for material transfer-points were scraped smooth, effectively lowering their elevations up to four inches. This will make it very easy to take all of the material, with a four inch margin of safety. In reality, all of the material in these piles is sand or rock, making it very easy to take everything down to the dirt on which they are piled.

Evidence is attached which substantiates that the alteration or relocation shall not adversely affect landowners upstream or downstream from the alteration or relocation. q Property Owner Date: tit/5 1 1°Pi(CRegistered Professional Engineer State of Colorado . ¢/ 3` 7 Date: / /y / ! / LAKU LANDING WATER SKI LAKES WELD COUNTY FLOOD HAZARD DEVELOPMENT PERMIT I hereby certify the proposed use at completion, two (2) water-ski lakes with backfilled, sloping shorelines, to be constructed in the FW (Floodway) District, will not cause any increase in floodwater levels during an Intermediate Regional Flood,and will not limit or restrict the flow capacity of the floodway. It is my understanding that in the final use configuration there will be no berming nor remaining stockpiles. The lake water surface will be -below the surrounding (pre- excavation) grade during non-flood periods. The assertion that the use will not cause increase in floodwater levels is based upon general knowledge of the following items of interest: 1. The excavated lake configuration provides some additional flood storage during filling of the lake freeboard volume as floodwaters rise. 2. The lake water surfaces will obviously offer no vegetation, irregularities, or obstructions to impede or retard flood flows as the previous (existing) topography and groundcover have. ititAbc.c %fc-75 ) Daniel P.

Federal EmergencfManagement Agency Region VIII Denver Perletartenter Cs 1P.O. Box 25267 �yo a Denver, CO §225-0267 = February 3 , 1992 Honorable George Kennedy Chairman, Board of County Commissioners Weld County 915 10th Street Greeley, CO 80631 Dear Mr. Kennedy: The purpose of this letter is to discuss the current non-compliant status of Laku Landing and the February 5 , 1992 Show Cause Hearing on this development. Today members of our Flood Branch and the Colorado Water Conservation Board (CWCB) were briefed by Chuck Cunliffe and Lanell Swanson of your Planning Staff on outstanding issues pertaining to Laku Landing. Deficiencies were itemized and communicated in the County' s September 3 , 1991 letter to Phil and Ellen Yastrow and Randy Hocking, The most serious of these was their failure to provide an engineer' s certification of the impact to the base (100-year) flood elevation of the sand and gravel piles still located in the regulatory floodway. This represents a violation of the County' s floodplain management regulations which requires a certification when a watercourse is altered or relocated and when the proposed development is located in the regulatory floodway. During the meeting we also discussed Mr. Yastrow' s submission of an " . . .analysis of a possible error in the floodway mapping at Laku Landing. . . " . A tape recording between Mr. Yastrow and Mr. Karl Mohr of our Office of Risk Assessment in Washington, D. C. reinforced our past communications with Mr. Yastrow on the procedures to follow when requesting a map revision. Since the above-mentioned analysis may be incomplete, until a thoroughly documented map revision request is submitted and approved by our agency, Laku Landing is noncompliant. Continuance of this violation will result in several adverse situations. First, potential flood heights in the area will be increased and adjacent property owners could sustain increased flood damage. Second, unless floodway development is properly and legally administered, it will set a precedence for future violations. Third, by allowing the violation to go unabated the, County will be subjected to probation action by the Federal Emergency Management Agency (FEMA) . -2- Probation is invoked as a result of a community' s failure to enforce its floodplain management ordinance. During the probation period, all new and renewal flood insurance premiums would be assessed a $50 surcharge. This surcharge is in effect until the probation is terminated. Currently there are 66 flood insurance policies in force for Unincorporated Weld County, Colorado. With the enactment of current and pending Federal legislation, this number could increase as lenders will be required to review existing mortgage portfolios and mandate flood insurance where necessary. We strongly urge the County to bring Laku Landing into compliance with Weld County' s floodplain management regulations. Despite our efforts over the past seven months, this issue remains unsolved. Therefore, should Laku Landing not be in compliance on April 5, 1992, our agency will initiate probation action. We are hopeful the County will take whatever action is necessary to avoid probation. If we can be of assistance, please contact Mrs. Virginia Motoyama of our Flood Branch at (303) 235-4830. Sincerely, I �( X0,1 e Yti Ce�uu� Dr. Marian L. Olson Regional Director cc: Mr. Brian Hyde, CWCB Mr. Leonard Boulas, COEM Ms. Nancy Carpenter, FIA-OLR SHOW CAUSE DATE: February 5, 1992 CASE # ZCH-82 USR-908 PROPERTY OWNER: Philip C. and Ellen Yastrow Randy Hocking ADDRESS: Laku Landing, P.O. Box 332 Windsor, CO 80550 LEGAL DESCRIPTION: Part of the S2 of Section 20, and part of the N2 of Section 29, T6N, R67W of the 6th P.M. , Weld County, Colorado. It is the opinion of the Department of Planning Services' staff that the following standards as approved for Case Number USR-908 are not in compliance. Development Standard #5: The property shall be maintained in compliance with the Weld County Flood Hazard Overlay District Requirements. Although several submittals have been received -by the Department of Planning Services' staff, a Flood Hazard Development permit cannot be approved. Some of the statements made do not comply with Weld County Flood Hazard Regulations. All required issues have not been addressed. The staff has received a copy of a submittal, dated January 6, and directed to FEMA in -Washington, D.C. , concerning a possible error in the floodway mapping. Development Standard #25: All construction on the property shall be in accordance with the requirements of the Weld County Building Code Ordinance. At the time zoning compliance hearing action was initiated, building permit applications had not been submitted for structures which had been placed on the site. Building permit applications have now been submitted but cannot be issued until a Flood Hazard Development permit has been approved. Development Standard #29: The Special Review area shall be limited to the plans shown herein and governed by the foregoing Standards and all applicable Weld County Regulations. Major changes from the plans or Development Standards as shown or stated shall require the approval of an amendment of the permit by the Weld County Planning Commission and the Board of County Commissioners before such changes from the plans or Development Standards are permitted. Any other changes shall be filed in the office of the Department of Planning Services. The stockpiles are not as shown on the recorded Use by Special Review plat. The applicants have not complied with all development standards and all applicable Weld County Regulations. Based upon the information, the Department of Planning Services' staff recommends that the Board of County Commissioners consider revocation of USR-908. INTERNAL CASE MEMORANDUM TO: File FROM: Lanell wan \ Current Planner i 1 NAME: Laku Landing K. LEGAL DESCRIPTION OF PROPERTY: Part of the S2 of Section 20, and part of the N2 of Section 29, T6N, R67W of the 6th P.M. , Weld County, Colorado. DATE: January 8, 1992 CASE NUMBER: ZCH-82 Lee Morrison, Assistant County Attorney, and I met with Brian Hyde, Colorado Water Conservation Board, Ken Lind, Attorney, and Phil Yastrow and Randy Hocking. Ken Lind said they propose the following: No new work will be performed on site except in accordance with the September 17, 1991 Floodway map, or an approved revision to the map. They are basing this proposal on a legal opinion that the current floodway map did not apply to work done prior to September 27, 1991. The County does not necessarily concur with this opinion. Brian -Hyde suggested we try to get FEMA to tell us in writing which maps we were obligated to use during 1991. The portable scale and storage building would also be placed outside of the floodway. The dock should be exempt from building permits, according to Mr. Lind. The County does not necessarily concur with this opinion. The applicants will be proceeding with Sections 65.6 (b) and (d) of the FEMA regulations regarding what they believe to be errors in the last floodway study. FEMA told Phil Yastow he may expect a verbal answer in 30 days. A letter would take longer. We discussed that any structures or stockpiles in the floodplain would still require approval of a Flood Hazard Development Permit. Brian Hyde discussed with the applicants the steps that need to be followed, which are: 1) Using the same base information used in the current floodway study, show that there were errors as the property previously existed. 2) Provide calculations showing the stockpiles and other improvements will still not adversely affect the requirements of Weld County. Should also address how other surrounding properties will be affected. 3) Address final "post-construction" conditions. Brian Hyde and Phil Yastrow discussed 500 feet cross-sections, "n" factors,, and other technical aspects of the application. eL,R '4-+`'' 4 • ‘tHr-H3/4 DEPARTMENT OF PLANNING SERVICES PHONE(303)356��•EST.STREET 400 Inge91510th STREET GREELEY,COLORADO 80631 COLORADO January 9 , 1992 Ms. Brenda Goranslo, Trial Attorney Office of General Counsel FEMA 500 "C" Street, SW Washington, DC 20472 Dear Ms .

Based on the information in Mr. Yastrow's report, it appears that the FIS study identified critical points in the floodway, optimized the floodway channel so that the water surface was at the designated height only at these points and then estimated the coordinates for all other points in the floodway. The study was then rerun to make sure that all other points along the floodway were at or below the designated height of one foot. Three points should be noted about this method of determining the floodway channel: 1) The floodway channel described in the report is only one of a large number of possible solutions. 2) The existing channel description is conservative in that the HEC-2 analysis shows that in most cases the floodway channel is less than half of the designated height and in one case the designated height was iactually below the surface of the floodway. 3) The channel as it is currently defined is overly restrictive in the area around Laku Landing; that is, it could ₹>e made significantly smaller. Mr. Yastrow re-evaluated the floodway channel using the the same methodology. However, in Mr. Yastrow's analysis he made the area around Laku Landing a critical point in the floodway channel thus keeping the water surface at the designated height. Mr. Yasrow's analysis still conservative and is only one of many possible solutions but it should be considered an equally valid analysis in that it also meets the criteria of keeping the water surface in the floodway channel at or below the designated height.

Introduction • 1.1 Purpose Pursuant to §65.6(b) of the FEMA document "National Flood Insurance Program and Related Regulations", the purpose of this document is to describe an error in the floodway mapping of the Cache La Poudre River near Windsor, Colorado. More specifically, the reach of the river in question is located in the North half of Section 20 and the South half of Section 29, Township 6 North, Range 67 West in the County of Weld, Colorado. All data provided in this document are referenced to the existing Flood Insurance Study (FIS), as performed by Simons, Li & Associates and revised by Baker Engineers. The included diskette contains all data generated in documenting the error as well as suggested corrections to the data. For the file names containing simulation data, see chapter 5 `Simulation File Names', page 4. 1.2 General The regulatory floodway is defined as the channel of a river or other water course and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface more than a designated height.' In Weld County, Colorado this designated height is one foot. The computer procedure for delineating a floodway includes: (a) the development of water surface profiles under natural conditions (i.e., prior to encroachment) and (b) the delineation of the des- ignated floodway that meets the requirements stated above. The procedure in HEC-2 encroachment routines allows a program user to make the preliminary estimate of a designated floodway in one operation of the program. Additional computer runs may be made to improve the acceptability of the floodway? This report will show the existing floodway boundary does not meet the above criteria, and will also show the additional computer runs needed to meet the criteria, and how the floodway boundary is changed as a result of this. 1 FEMA, "National Flood Insurance Program and Related Regulations", §59.1, p25I.

Existing Study The simulation data used for the current FIS study indicate that there is never greater than a one foot rise in the waters of a base flood discharge, if the flow is restricted to the floodway. Table 1 shows the change in flood water surface elevation for each cross section in the study reach. Note that in only two cases does the increase in water surface elevation due to the floodway equal one foot, and in all other cases it is less. This means the existing floodway designation is overly conservative. cross section change due to number floodway (ft.) 129630.000 .6 130980.000 .6 132030.000 .3 133300.000 .4 133330.000 .4 136450.000 .0 139690.000 -.1 145760.000 1.0 147200.000 .7 148950.000 .7 148960.000 .6 149580.000 .9 151100.000 1.0 152250.000 .2 152300.000 .0 152340.000 .0 15P.190 n00 0 Table 1. Summary of Floodway Increase in Water Surface Elevations for Existing FIS The cross section which intersects Laku Landing is #139690, and as shown in table 1, there is actually a drop in the water surface elevation as a result of the floodway encroachments. The floodway regulations allow for a one foot increase in the water level, so it is clear that the size of the floodway at this (and most other cross sections in the study) should be smaller. 3. Suggested Floodway Error Corrections One difficulty in using the automatic encroachment routines in HEC-2(encroachment methods #4 and #5) to determine the floodway boundaries, is that the FIS, as revised by Baker Engineers, has much of the study reach containing no overbank areas, i.e., the entire flood plain is considered river channel. In addition, there is considerable distance and therefore interpolation between existing GR ( r" - `1. Suggested Floodway Boundary Improvements 3 stations. "If there is a large distance between adjacent stations and the ground profile is sloping, the computed encroachment stations will not provide for the proper reduction of conveyance" 3. For these reasons, it is necessary to perform the floodway designation by the manual technique of encroachment method #1. The process for this method is to manually change the floodway boundaries until the desired change in base flood discharge water level is equal to one foot. By-modifying the encroachment station locations_on the cross section which intersects the lake area of Laku Landing(#139690)and the cross sections directly upstream and downstream(#136450 and #145760) a base flood elevation increase of exactly one foot is achieved at cross section #139690. The encroachment station locations for the existing and_corrected simulations are shown in table 2. cross section existing study corrected simulation number left and right left and right 136450 600 3000 1800 2910 139690 600 2800 407 1200 145760 1400 3300 1200 3300 Table 2. Floodway Boundaries For Existing and Corrected Simulations Summarizing the output oT HEC-2, the changes in water surface elevation during a base flood discharge due to floodway encroachment are shown in table 3. Although there are still cross sections with an overly conservative floodway, the increase in water level at Laku Landing due to the corrected floodway is exactly one foot. In reality, the value at all of the cross sections should be one foot, but using the methodology already utilized by the current FIS, described by Paul Clopper of Simons Li & Associates, "... critical areas such as bridges and other points of interest were defined and those locations were given a floodway boundary calculated by the one foot rule. Then the rest of the floodway was drawn in by freehand, following the general course of the base flood discharge water flow." Using this same methodology, we have now defined Laku Landing to be a critical area and computed a new floodway boundary to exactly match the one foot rule at that location. 4. Suggested Floodway Boundary Improvements It is possible to make the floodway boundary even more accurate by adding more cross sections to the area of interest. John Liou of FEMA (Denver) has already stated that we do not need more cross sections through Laku Landing because there is no reason for our study to be any more 3 Corps of Engineers, Hydrologic Engineering Center, "Floodway Determination Using Computer Program HEC-2", pl-1, 'raining Document No. 5, May 1974 Simulation File Names 4 cross section change due to number .floodway (ft.) 129630.000 .6 130980.000 .6 132030.000 .3 133300.000 .4 133330.000 .4 136450.000 .6 139690.000 1.0 145760.000 1.0 147200.000 .3 148950.000 .8 148960.000 .8 149580.000 1.0 151100.000 1.0 152250.000 .2 152300.000 .0 152340.000 .0 1.59390 000 0 Table 3. Summary of Floodway Increase in Water Surface Elevations for Corrected FIS accurate than the rest of the FIS reach on the Cache la Poudre River. We were told, however, that by adding more cross sections, it will most likely benefit us because the floodway will shrink. Based on these statements, we intend to survey more cross sections on the property to more accurately depict the physical attributes of the flood plain. At the time we complete our topographic surveys of these additional cross sections and perform new simulation runs, we will submit the data to FEMA as required by §65.7(d) of the FEMA document "National Flood Insurance Program and Related Regulations". 5.

Box 332 Windsor, CO 80550 LEGAL DESCRIPTION: Part of the S2 of Section 20, and part of the N2 of Section 29, T6N, R67W of the 6th P.M. , Weld County, Colorado. It is the opinion of the Department of Planning Services' staff that the following standards as approved for Case Number USR-908 are not in compliance. Development Standard #5: The property shall be maintained in compliance with the Weld County Flood Hazard Overlay District Requirements. Although several submittals have been received by the Department of Planning Services' staff, a Flood Hazard Development permit cannot be approved. Some of the statements made do not comply with Weld County Flood Hazard Regulations. All required issues have not been addressed. No additional items have been received from the applicants since the Probable Cause Hearing held on November 20. A letter from the Colorado Water Conservation Board is attached. The letter refers to an on-site inspection held on December 3, and supports the staff's opinion that Weld County Flood Hazard Regulations have not been met. Development Standard #25: All construction on the property shall be in accordance with the requirements of the Weld County Building Code Ordinance. At the time zoning compliance hearing action was initiated, building permit applications had not been submitted for structures which had been placed on the site. Building permit applications have now been submitted but cannot be issued until a Flood Hazard Development permit has been approved. Development Standard #29: The Special Review area shall be limited to the plans shown herein and governed by the foregoing Standards and all applicable Weld County Regulations. Major changes from the plans or Development Standards as shown or stated shall require the approval of an amendment of the permit by the Weld County Planning Commission and the Board of County Commissioners before such changes from the plans or Development Standards are permitted. Any other changes shall be filed in the office of the Department of Planning Services. The stockpiles are not as shown on the recorded Use by Special Review plat. The applicants have not complied with all development standards and all applicable Weld County Regulations. Based upon the information, the Department of Planning Services' staff recommends that the Board of County Commissioners consider revocation of USR-908. >- a INTERNAL CASE MEMORANDUM • TO: File FROM: Lanell J.

STATE OF COLORADO COLORADO WATER CONSERVATION BOARD Department of Natural Resources .._ 721 State Centennial Building 1313 Sherman Street Denver,Colorado 80203 Phone: (303) 866-3441 Rov Romer Gosernor December 12, 1991 Da°,n'N.Walker Director Mr. Chuck Cunliffe, Director Weld County Department of Planning Services 915 10th Street Greeley, CO 80631 Dear Mr. Cu inl-ffe:� After reviewing the materials you sent me concerning the proposed Laku Landing water ski development and after visiting the site with you, I would like to comment on the proposal. There appear to be two floodplain management issues related to the site. First is the issue of "temporary" placement of fill in the floodway of the Cache la Poudre River. Second is the issue of permanent fill and construction of structures in the floodway. In the event of a flood, the stockpiles already on the site would act as dams and obstruct flow. I saw three different locations on the site where fill is stockpiled. Two are definitely in the floodway. In view of the fact that filling has been going on for about six months already, I would not consider the activities temporary. All of those pile in the floodway must be removed from the floodway or a floodway revision must be sought. Even if they were temporary, such activities would require a floodplain development permit. Their effect on the floodway would need to be properly mitigated for such a permit to be issued. The "mitigation measures" proposed (sandbagging) do not adequately deal with the rise in water surface that would be caused by the filling. It also appears that the cross-sections utilized in the analysis do not adequately represent the filling that has occurred. The one cross-section showing any filling only touches portions of some of the piles. I disagree with the assertion that no further cross- sections are needed, whether for the "temporary" condition or the proposed permanent condition. Cross-sections need to represent the changes at the site better than the one cross-section does. I would suggest that the model use two cross-sections going through the filled areas. With appropriate cross-sections in the hydraulic,model, the proponent can then try to demonstrate that the ultimate development condition results in no rise in water surface elevation due to fill in the floodway. eRr:rt --, -I MT. Chuck Cunliffe December 12, 1991 Page two The permanent regrading of the site, the construction of review stands for judges, the construction of any spectator area, and so on constitute development in the floodway. As you know,floodway regulations prohibit filling in the floodway that causes any rise (anything greater than 0.00 rise!). If a rise is proposed, the floodway must be revised. As with the "temporary" condition, it appears that a more representative topographic model , in terms of cross-sections, should be employed by the proponent. Another important engineering issue is the issue of roughness ('n' value). That issue needs to be addressed differently. It is true that the 'n' value of the water in lakes is lower than that of rough ground. If, however, that lake is just upstream of fill (i.e. spectator area or stockpile), then floodwaters could not get all the way through the obstructed area. They would have to flow around the obstructed area. In such a condition the lake surface would be part of an area of ineffective flow. In other words, floodwaters do not experience the hydraulic benefits of reduced 'n' values if immediately downstream they are confronted by a major obstruction. The 'n' value should be reduced only for those areas where floodwaters can actually be conveyed. In view of the current and proposed topography on the site, the averaging technique for reducing the 'n' value, specifically as discussed on page 4 of the HEC-2 Study of Lake Landing, does not seem appropriate. Averaging that distinguished between areas of conveyance and areas where flow is obstructed would be more appropriate. The proponents should, therefore, show where the unobstructed flow paths are and change 'n' values only in those areas. I hope these comments are of help to you in resolving this situation. Please let me know if you have any questions or concerns. Sincerely, Brian R.

He said John Liou is completely "taking Weld County off the hook at this time" . He has added more information to the report that we got last week. He said Connell is basically finished with the first lake. About 75% of reclaiming is done. There is still some material left on the property. They are still trying to address how to minimize the potential hazards. He said John Liou is worried about potential sediment transport. They are still talking about annexing to Windsor, but had decided not to annex until this issue has been dealt with. Recently, Windsor has joined FEMA. They are now working on the annexation agreement with the Town of Windsor. We will be getting another letter from them addressing increases in flood level and sediment transport.

Box 332 Windsor, CO 80550 Dear Mr. and Mrs. Yastrow and Mr. Hocking: The Department of Planning Services' staff has completed its review of your submitted Flood Hazard Development Permit application. The application as _ submitted does not adequately address all of the applicable conditions listed in Section 53 .6 of the Weld County Zoning Ordinance. You cannot be selective in what Sections of the Zoning Ordinance you wish to address in your application, but you must address all of the conditions in Section 53.6 that apply to the use of your property. The application should state that the entire property is in the floodway. The most recent study completed by FEMA shows your entire property is located in the floodway. You also need to identify the FEMA flood insurance work maps that you referenced in your Flood Hazard Development Permit application as the "source of information" . The Zoning Ordinance requires that the construction of dwellings shall have the lowest floor, including the basement floor, elevated to or above the regulatory flood datum. Exact elevations of the intermediate regional flood and the lowest floor of the dwellings at the construction site will need to be provided. The Zoning Ordinance requires that structures other than dwelling units must be floodproofed either by elevating or by making the structure watertight below the regulatory flood datum. The narrative and certification should address this requirement for structures such as the judges' tower and any structures used with the mining activities . There is no record of any building permits for the scale and scale house presently located on the property. You need to apply for the building permits immediately. The building permits will not be issued until the structures are included in Flood Hazard Development permit application and it is approved. _Phil and Ellen Yastrow -Randy Hocking _September 3 , 1991 _Page 2 "The Zoning Ordinance requires that no encroachments, including fill, new construction, substantial improvements, or other development shall be permitted unless certification by a registered professional engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of an intermediate regional flood. The certification submitted with your -application addresses the site after construction only. Certification is needed from an engineer regarding the fill placed on the property during construction and the mining activities that are occurring on the property. The certification needs to be supported with detailed engineering data to support the conclusion stated in the certification. The Zoning Ordinance specifically states that land within the floodway shall not be used for the storage or placement of sand and gravel and other mineral deposits or fill material. The final decision to allow stockpiles in the floodway will rest with the Board of County Commissioners. Your application should address in more detail your plans for storage of the stockpiles and the effects the stockpiles will have in the event flooding should occur. The maps submitted with the application did not accurately show the actual construction, mining activities, and placement of stockpiles and berms that are occurring on the Qroperty observed during inspection of the property on August 16, 1991. information detailing the timing and phasing of the mining extraction, stock- piling, and operations should be submitted for review. Detailed engineering data showing the existing topography before the mining activities began and the final planned topography needs to be submitted for review. "The detailed engineering data requested in the above paragraphs shall be certified by a registered professional engineer and should include, but not be limited to, any changed hydraulic conditions on the property, a hydrologic analysis with a description of the methodology used, printouts from the calibration model used in the analysis, a "before and after" topographic map that shows the locations and alignments of all cross- sections used in the hydraulic model, and "as-built" plans. The engineering data must account for the effects of the mining activities (extraction, stockpiles, and berms) that have occurred and continue to occur since the adopted FEMA Flood Insurance Study hydraulic model was developed for your property. I would like to remind you that until Weld County approves the Flood Hazard Development permit, you continue to be in violation of the Weld County Zoning Ordinance and are subject to additional legal action being considered by Weld _County to remedy the violations occurring on your property. Z am requesting that you submit the additional information on or before September 20, 1991. Or ci ; 't : Phil and Ellen Yastrow -Randy Hocking S eptember 3 , 1991 -Page 3 You should be aware that if the County does not have qualified staff or referral agencies are not able to adequately advise the County regarding the review of Flood Hazard Development Permit application, the Board of County Commissioners may authorize that the review be performed by a qualified outside consultant and that you will be responsible for the costs of this review in accordance with Section 29 . 3 of the Weld County Zoning Ordinance. II you or your engineer have any questions about the additional information that is being requested, please call me. -If necessary we can schedule an appointment to review the Flood Hazard Development Permit requirements and Section 53.6 of the Weld County Zoning Ordinance.

I explained that Z had concerns with the Flood Hazard Development permit application submittal regarding the lack of information on the construction phase (berms and gravel stockpiles on property in the Iloodway) and the certification.

DATE: November 6, 1991 CASE NUMBER: ZCH-82 I spoke with Mr. Phil Yastrow today regarding the zoning compliance case. I informed him a hearing date would be set and went over my October 29 memo with him. He said the scale house was being disassembled. The first lake is finished. I also spoke to Randy Hocking, who asked about the authorization for legal action which he had received in the mail. He said the small shed would probably be removed instead of including it on the Flood Hazard application. t// , Chuek-Gunl#€€e—i}LreeEer— ca'z October 29, 1991 • Ail • CC OR ADC1L-.L— Swanson=-Cur ^r P1 er Subject- I.-kku Landing nrrober—J 7 PIMP c,ihmi tral As you have requested, I have reviewed the October 17 submittal from Phil Yastrow and Randy Hocking regarding their Flood Hazard Development Permit application and it's relevance to your letter of September 3. I submit the following: The new narrative does state that the entire property is in the floodway. A drawing is also provided. Specific map numbers are not provided, but the narrative refers to a "newer study, which was made available for public purchase September 26, 1991" . Exact elevations of the lowest floor of the proposed dwellings at the construction site are not provided, although they do provide the extreme, "worst-case" elevations, which may be helpful. A drawing is also provided of this area, the elevation of the intermediate regional flood and where the lowest floor of the dwellings would have to be to meet the Yaquirements. The judges' towers are addressed. The application states that the wood columns will be anchored to a sufficient depth to prevent flotation, co' lapse or lateral movement of the towers. The platforms will be elevated above the regulatory flood datum to avoid alteration of the water course. The narrative states the exact details of construction are not known at this time. Building permit applications have been submitted for the scale house and the shed. I do not see these structures addressed in the narrative. The narrative states that the report has shown that any floodway Development at Laku Landing will result in no rise in the water levels of -an intermediate regional flood. However, during the construction phase, the narrative discusses considering methods of flood damage minimization in case an intermediate regional flood were to occur while there are stockpiles on the property. The placement of material will fall into one of the two stockpile regions which are shown. The placement, of the -material in piles which are parallel to the direction of water flow, causes a net effect much less than perpendicular or random placement, according to the application. The maximum rise calculated for the water surface of a 100-year flood, as calculated by HEC-2, is 0.2 feet. Therefore, the narrative states, as long as the material is placed in _these regions, the rise would never be greater than 2.4 inches. Regarding sediment transport minimization, they propose that any material stockpiled on the property will be protected by sandbags Tilled with sand and gravel 3/8 inch and under. The sandbags will protect the stockpiles and the height of the sandbag wall will be at least the height of the intermediate regional flood water levels, according to the application. .Laku Landing Memorandum October 29 , 1991 Page 2 The anticipated schedule for stockpile removal and excavation of the second lake is not given. He says that Connell Resources feels that the market for the material will be strong enough to strip the topsoil and begin dewatering activities on the second lake this winter. -The narrative states all material will be removed by the completion date designated by the USR, which is August 1, 1996. Stockpile areas are shown on a drawing with the narrative. The applicants have asked for review of this material for completeness before they submit it for final certification by the engineer.

DATE: October 7, 1991 EASE NUMBER: VI-1771 I returned Phil Yastrow's telephone call. He told me that he had received the various letters Trom the County. He indicated that he is still working on revising the Flood Hazard Development -Permit application materials addressing the issues in my letter of September 3, 1991. He plans to submit the revised materials to the County within the next two weeks. He did indicate that the revised Hec II model would address the construction -phases and stockpiles located on the property. Mr. Yastrow's asked that final certification of the information by his engineer not occur until our office is satisfied with the "content" of the information. I told him that we would work with him. He indicated that Mr. Hocking would be applying for the required building permits sometime this week. He asked about -purchasing a copy of the Weld County Building Code Ordinance. 1 told him that it was available for a cost of $3.00. NCY m-44, Federal Emergency Management Agency " Region VIII Denver Federal Center P.O.-Box 25267 oy y;�----- . Denver, CO 80225-0267 October 3 , 19-91 D r, Mr. Phil Yastrow 0CT b 7 1991 T. D. Box 332 v — Windsor, CO 80550 -Weld County Planning Dear Mr. Yastrow: The purpose of this letter is to discuss the current status of taku Landing and its impact on Weld County 's floodplain management program. Since there seems to be a misunderstanding of when _regulatory compliance is required and the role of our agency with regard to floodplain 'development, this letter will attempt to add clarity as well . The National Flood _Insurance Program (N-FIP) regulations serve as minimum standards that all NFIP-participating communities are required to implement. In addition to general floodplain management standards which apply in all areas of special flood hazard (also known as 100-year floodplains) there are specific restrictions to be imposed for development proposed in a regulatory floodway delineated by our agency. Before proposed development (structural or nonstructural) commences in the regulatory floodway, the developer must first demonstrate that "no increase to the base (10O-year) flood elevation" will occur as a result of the development. The responsibility for providing the demonstration rests with the developer and his engineer. After the developer ' s engineer has completed an analysis of the development and has certified what the impact will be to the base flood elevation, this information is provided to the community's floodplain regulatory authority. A community can accept or reject floodway proposals that do or do not cause an increase. What is important to remember is that prior community approval is required before any development in the regulatory floodway begins. Since the NFIP requires communities to adopt and regulate a regulatory floodway once our agency has delineated it, all changes to the current effective floodway must be reported to our agency. St is at this point that our agency provides direction - o the 'developer and community to ensure that the revised floodway meets our agency 's criteria for a floodway revision. It is our understanding that the Zaku Landing proposal currently does not satisfy all of Weld County' s floodplain management criteria which was outlined in the County ' s letter of September 3 , 1991. As discussed above, floodway development must first meet community requirements. If a floodway revision is necessitated, then our agency would assist in the development of the floodway revision. Please note that the only time our office will be involved with your development is after the development has been brought into compliance and a floodway revision will be undertaken. We cannot stress enough the criticality of the current status of Laku Landing' s noncompliance with Weld County' s regulations. Not only is the County' s NFIP status in jeopardy, but you could face additional problems if adjoining property owners to your development incur flood damages as a result of it. We are confident that you will undertake whatever measures are necessary to bring Laku Landing into compliance. All future correspondence and technical data should be directed to the County Planning Services office for review and approval. This office will maintain periodic contacts with the County to determine what progress is being made. Your cooperation is appreciated.

Box 332 Windsor, CO 805.0 February 4, 1992 Lanell Swanson Weld County Department of Plabning Services 915 10th Street Greeley, Colorado 80631 Dear Lanell: The enclosed document entitled "HEC-2 Study of Laku Landing" contains the modified engi- neering data requested by The Colorado Water Conservation Board. More specifically, Mr. Hyde asked for additional cross sections to more accurately depict the construction conditions, as well as a different approach when modeling roughness during the construction phase of our project. The results of the data show 1 hat no matter which floodway is used, new or old, we are not in violation of any FEMA regulations. This is because the additional topography used shows no -rise in the water levels of an intermediate regional flood during construction as well as the as-built condition. If the county determines that the new floodway has been in effect even before it was adopted, the only regulation we are in violation of is the county's which states no stockpiles are to be allowed in the floodway. The enclosed computer diskette contains all of the simulation input and output used by the HEC-2 water surface profiles program as well as survey data used to define the new cross sections.
