Although lt would appear that Colorado may be perlpheral to the eagle's nestlng range, the f lrst recent breedlng by bald eagles r^tas documented at Electra Lake in 1974 and the number of nestlng pairs qradually lncreased to 9 by 1986.

Due to the species'federal and state endangered status, ít is important to monítor nesting activity, document productivity, determine key hunting habltats and lmplement management actlons where necessary to encourage populatlon expanslon. Landowner agreements, habitat manipulation to maintain or encourage prey availability, and nest site stabilizatlon practices are loglcal management tooìs that may be utilized.

Need predoninantly evergreens from the bridqe to the east sideof the 3/4 ac. lot which lies on north side of entry road.The deciduous trees will not provide adequate =".""ñirrq ofpeople and noise. 3- spacing of evergreens should be closer, around 6r, until treesmature and fill out. Trees can then be thinned andtransplanted to other locations in the developrnent. Thescreening along the entry road on the north side needs to bedense so as to total-Iy block nest views. 4 " Plant more evergreens by bridqe on south side of entry roadwhere the 3/4 Ac. homes are located. 5.

If observer is hired: $A.so7frr., Spotting scope Approx. $3oo.oo, Tripod for scope Approx. $1oo.oo. observer provide own binoculars. Misc. sugqestions 1) ff eagles leave nest, r^re may want observers to follow birds tohelp determine feeding sites or alternative roost sites. 2) Observation locations. along 109 Rd. Use Leon Chuc's driveway or puII off a/L âÕ l.nl. hrri 'l cli no envel o nê sIt appears that sink holes will dictate building envelopelocations. Due to lot size there is not much room for adjustment. The building envelopes by the bridge on the south side of the entry road do concern me. If these can be placed as far back on the lot t- 2 as possible, it nay help. The remaininq 3/4 ac,. envelopes are ok. Low profile homes would be best in these locations as well as thelot on the north side of entry road and west side of flole #11 road. hlildlife Corridor Easements The corridors as outlined may allobr some movement. However, once development build out is achieved I do not think they will be of much value as they lead into the main development. They mayprovide access for deer and elk to the golf course which couldresult in damage to fairways and greens. What may determine use ofthese corridors is the amount of activity associated with the homesites. 9_È_þ_e_r_ ç_o_n$ents I have 2 other sugqestions that you may wish to consider. Post eagle buffer zone so homeowners and people associatedwith the development know the boundaries and restrictions.This may help prevent unexpected problems. Install fence around nest tree to prevent vandalism and damageto the nest tree. There will be alot of people travellíngclose to the tree when HoIe #fO is able to be played. This fence could be placecl at the l-OO yard mark from nest and along Hole #tO.

McNure Mr. Nick Mezei U.S. Army Corp of Engineers Western Colorado Field Office 402 Rood Ave.' Rm. L4 Grand Junction, CO 81501 RE: Aspen Glen-Project 199375069 Gentlemen: Initially, on behalf of the Aspen Glen companyr \dê wish to thank you for your time in meeting with us on June 9 | 1993. We appreciated the opportunity to clarify the concept of the. Eagle nããt Buffer Zone and the manner in which the concept will be employed to protect any bald eagles which may be present within the Aspen Glen Project. As far as the Aspen GIen Project is concerned, the concept of an Eagle Nest, Buffer Zone was first articulated Þy three gagle experfs who investigated the situation: Mr. Mike Ï{hitfield' Moñtana State University; Dr. Rick Knight, Colorado State University; and Mr. Jerry Craig, Colorado Division of Wildlife. The planr âs conceived by the experts' \ías approved by As_pen_ GIen and the Colorado Divísion of wildlife. The plan involved the creation of an area around the nest tree ín whieh only cert-ain clearly defined activities can occur. The terms and conditions of the pIãn were set forth in a letter from the Colorado Division of V{ildlife to the Garfield County Planning Department dated April 26' Lgg2 (hereafter DOW letter), It rdas the intention of Garfield County and Aspen Glen to have all of the terms of the DOW letter incorþorated into Garfield County Resolution 92-056, the Resolution of thä eoard of County Commissioners of Garfield County approving the Aspen GIen PUD. -the guffer ?,one provisions are set forth in paragrãphs 6-16 of Garfield county Resolution No. 92-056. The Buffer Zone itseLf is an overlay zor.e district. !{e have attached a map hereto (Exhibit F'-16 as referenced in paragraph 6 "{the resolution) which depicts the Buffer Zone. AII future maps and plats of that'portion of the Aspen Glen Project will depict the Mr. Grady L. McNureMr. Nick MezeiU.S. Army Corps of Engineers June L7, L993 Page 2 Buffer Zone as shown on the attached map until and unless theBuffer zone is removed. For so long as the Buffer zone is inplacer Do activity can occur within that Zone except in accordancewith the terms of the Buffer Zone district. It is the position of Garfield County, and Aspen Glen agrees,that "no construction of dwelling ulits or human activities, éxceptas established herein" will occur within the Buffer Zone lparagraþh6 of Resolution 92_-056). Garfield County will have the ãuthórityto enforce the Buffer Zone restrict,ions as they are included withinthe zoning ordinance and will remain for so long as the Buffer Zoneremains in p1ace. The Buffer zone will remain in p1ace, with allof its restrictions, until such time as the Colorãdo Divisíon ofwildlÍfe allows removal of the Buffer Zone, and the Board of CountyCommissioners acts to remove that Zone. fn practical terms, thiË means that only the limited activity set forth in the DO!{ letter isgoing to occur within the Buffer Zone until and unless the Divisionof ffildlife, after consulting with the united States Fish and!{ildlife Service, if it so desires, authorizes the elimination ofthe Buffer Zone. I have conferred with Don DeFord, Garfield CountyAttorneyr olt this issue, and he confirms that t,he foregoing is théintended and correct interpretation of the Buffer zone provisionsof Resolution 92'056. Please feel- free to contact Mr. DePorddirectly if you wish to confirm this matter with him. !{e understand that you have concerns that there is someinconsistency between the Buffer Zone restrictions as contained inResolution 92-056 and the DOW letter. Againr any inconsistency infact was an oversiqht by all parties, ãnd the eoncerns r.rili beresolved as follows: -1. Bui]-dinq Fnvelopes. Aspen GIen's preliminary plan Application will depict a building envelope for each lot within thePUD. The location of the building envelopes on the 3/4 acre lotsadjacent to the Buffer Zone will be approved by the Division ofwirdlife as required by paragraph number 3 of the Dorf letter. 2. One-Hundred Foot Setback on Ouarter Àcre Lots. ParagraphNo. 6 of the DOVÍ letter requests thaL there be a 100-foot setbackfrom the river on the riverside lots within the ä-acre zonedist,ríct on the west side of t,he Roaring Fork River. As explainedin paragraph Lt above, all lots within Aspen Glen will havebuilding envelopes. The building envelopes for the riverside ,4- acre lots will be located such that, there will be a 100-foot .tJ Mr. Grady L. McNureMr. Nick Mezei U.S. Army Corps of Engineers June L"7 , L993 Page 3 setback from the ordinary high water line. Aspen GIen will obtain DOW's approval of these building envelopes to assure that nobuilding envelope for the riverside ]¡-acre lots intrudes on the 100-foot setback. 3. Screeni¡rg. Paragraphs 4 and 7 of the DOlf letter setforth certain requirements regarding screening of the Aspen Glenfacilities from the nest tree. Aspen GIen will submit to the DOV{ a screening plan consistent with aII provisions of paragraphs 4 and7 of the DO!{ letter and obtain approval from the DOll for such screening plan. The screening plan will include vegetative screening for the k-acre residential lots on the west side of the river. The Aspen Glen screening plan will also provide for a screen on the downstream side of the bridge across the river. This screenwill be designed to minimize the noise and visual impact of traffic crossing the bridge upon the nest site. Because Aspen Glen wishesto make sure that the bridge screen is consistent, with otherarchitectural features of the project, the exact design of thebridge screen will not be available at this time. However, the bridge screening plan will be approved by DOT{ and Aspen Glen wi}l submit drawings of the approved plan to the Corps of Engineers. 4. Monitoring Plan. Paragraph No. L of the DOff letter provídes that a program to monitor the presence of the eagles will be established and coordinated by DOI{ and Aspen GIen. Aspen GIen has commenceci work with IlOw- to create an acceptable monitoringprogram. The approved monitoring program will be implemented and be continued at the expense of Aspen GLen. 5. Doq Restrictions.Resolution 92-056 provides that only one dog shall be allowed for each residential unit within the PUD (Condition 42 of the Resolution). Further, such restriction will be imposed and enforced through restrictive covenants (Condition 42l' and final plat notes (Condition 67(D)). This provision is inconsistent, with the DOI{ letter in that the DOW requested that no dogs be allowed within the 3/A-acxe zone district southeast of the nest, the club villas on the west side of the river, and the L'o-acre zone district on the west side of the river. By both covenant andplat note, Aspen GIen wiII provide that no dogs be allowed in those areas. Mr. Grady L. McNureMr. Nick MezeiU.S. Army Corps of EngineersJune L7, 1993 Page 4 _.6: Construction Actívity. Paragraph 9 of the DOW letter andCondition 10 of Resolution 92-056 leC forth restrictions onconstruction activity wit,hin the Buffer Zone and adjacent areas.All _parties agree that the wording of those provisionã is somewhatconfusing. .Aspen GIen agrees wltt¡ the Unitea States Fish andwildlif e service and the Ðow that the word rror,, in the f irstsentence of both such provisions should be deleted so that thereferenced pa.ragraphs clearly refer to "construction activity. "Furthermore, it is agre_ed that the area where construction activityis regulated be more clearly defined to incl,ude the 1gt.h hole. We believe that with two exceptions this letter addresses alItÞ" poínts that, $¡ere discussed at the meeting of June g,1993. Those two exceptions are potential wetlands impãcts of the outfallline and structure for the prop_osed wastewater treatment facíIity,and a clarífication of the wetland enhancement measures that wíiibe undertaken by.Aspen Glen. !{e believe that you have already t oÍwill soon, receive a separate letter from Ãquatic and welÍandConsultants, Aspen Glen's wetland consultants, which separatelyaddresses those two issues. T"I yogr further information, since our meeting of June g Iofficials of Aspen Glen have_ been wofking closely with Kevin Wrighi,of the Division of lrítdlife regarding the vegetative ""r""níngplalt bridge screening pran, buirding enve-lopes, and eagrémonitoring pIan. rt is our understanding that ã great. deal ofpositive progress has been made on those iséues and tñat Aspen Glenis now in the process of makinçt some final- revisions to thoie plansas suggested by DOI{. It is ûur fi¡rther ur¡derstanciing thaL DOW-witlsoon issue a letter setting forth its posit,ion on tñose items. Aspart, of that process, Aspen Gren has agreed, at the suggestion ofD9Il to post the e,agle Buffer Zone so homeowners and other peoplewill know the boundaríes of the Buffer Zone, and. to install ifeircearound the nest tree, at a location acceptable to Dow, to preventvandalism and damage to the nest tree. . A"Pen GIen neither desires nor believes that its project willimpact.bald eagì.s5. This commitment is clearly evidêncãa by theprovisions of the DOW tetter and the applicable provisioris ofGarfield County Resolution 92-056. This commitmeñt is furtherclarified and implemented by the provisions of t,hís letter. lrtetherefore believe t,þat upon your receipt of this letter you willhave the necessary information at hand to allow you to prãceed to Mr. Grady L.

Per our meeting last Thursday, June l-7 and your June 16 letter, wê have modified our plans in the following Í¡ays: l-. The access J-oops aJ-ong the entry road have been eliminated. The berm and screening have been continued straight al-ong the entry road. 2. We have eliminated the Lodge PoIe Pines from the bridge to the east side of the 3/4 acre lot which lies on the north side of the entry road. These trees have been replaced with 50 8-10' Spruce and 50 LO-L2' Spruce. frle have added another 60 8-10' Spruce in this area. We have also almost doubled the road to help create the AspenGlen the size of the berm to l-O' hiqh from sol-id screen reguested by the CDOW. 3. AII trees Lo-Lz ' high and L4-L6' high are already too big to plant six feet apart. We believe that the measures outiined ín #2 above satisfy the objective of your request to plant the trees six feet apart. rf you have any questions regarding this issue, pJ-ease talk to our landscape architect Greg Mozian directl-y. 4. More everçtreens have been planned by the bridge on the south side of the entry road where the 3/4 acre homes are located. 5. Landscape screening has been planned for the first seven I/4 acre riverside lots on the west side of the river to the island. Here 7O 2-2 7/2" cottonwood trees wil-I be interspersed with existing mature vegetation. 6. Al-1 building envelopes al-ong the river in the I/4 acre zone district are now l-OO' from hiqh water mark. l i I The Aspen Glen Company . 555 E. Durant Avenue, Suite 4A .

This wilI totally block all- everyday vehicular and pedestrian traffic on both sides of the bridge. Construction traffic wiIl not be aIl-owed to use the bridge when the eagles are present. 8. I{e agree to post the eagle buffer zone so the boundaries are evident to all. 9. We agree to install a fence around the nest tree to prevent vandal"ism and darnage to the nest tree. This fence will be placed at the 1-00 yard mark from the nest and along HoIe #1-O. I am sending you the revised plan overnight delivery so that you can see these chanqes Tuesday morning.

Vegetative screeninq For Blad Eagle Nest Protection Zone The plan should be ãdequate with the changes you made as outlined in my 6/16/93 letter tó you and your 6/21/93 letter to me- If the berm raised to 10' along with the veqetative screening adjustment provides the solid screãn we suggested, then the vegetative screening plan should be adequate. 2. 3/4 Ac. Lot Buildíng Envelopes - As I mentioned in my 6/16/93 letter, the sink holes dictãte envelope location' Due to lot size there is not much room for adjustment. Low profile homes in these locations would be best. Placement of homes as far back as possible, especiatly on the lots just souLheast of the bridge may be helpiul.- If this has been done then envelopes are located adåquately.

Over the past months I have net withAspen Glen, U.S. Army Corps of Engineers, and U.S. Fish andúüildlife Service to ad.dress wil-dlif e concerns, mainly the baldeaE1e. I have attached copies of pertinent letters you may wish toreview (6-16-93 | 6-21,-93, 7-20-93, 7-3A-93). These are some of thesame retters referenced by The u.s. corps of Engineers underSection X of the application. 1-. Dogs have been restricted to l/hone as outlíned in #1-4 of thePUD. However, it is important to also have a kennelrestriction in place and that the kennel be constructed beforethe c.o. is issued. This becomes very important for thosehomesites west of 109 Road if those homesites are alloweddogs. lrfithout a kennel restrictiono¡{prohibition, these dogswill have a negative impact to winte'ring deer and elk along 109 Rd. and the mesa directly above it.
