I have completed mv geologic investigation of the approximately 23 acre tract between Hawk Creek and the Crystal River for purposes of satisfying House Bill 1041. Thd parcel lies in the NW 1/4 of Section 29, T 10 S, R 88 W, mf the Si:th P.M., within the Redstone 7 1/2 minute quagrangle. Pitkin County, Czlorado. Although the parcel is la-gc, only the western corner near the Crystal River was studied as a potential building envelope. '' `agraph/caiI`, this site is within tvs ulinr floodplain of the Crystal River and could be termed a P001 -1y dezined terrace' The lot is heavily wooded, including large conifers. There are linear mounds associated with Hawk Creek to the south and the remnants of twq bridges as shown on the accompanying map with an old dirt road which once connected them. Except for the linear mounds and a well defined swale aw shown, the general area of the site is nearly- level-., _ r�n bedrock formation in the entire -area is the Pennsylvanian ' -Fornian age Maroon Formation which dips roughly 30 degrees to h4e west on the mountainside above the site. The Maroon Fcrmuticn in this area consists mostly of siltstones, s^rdstones, and a few conglomerate units cemented by a red, iron compound called hematite. The building envelope itself most probably lies on alluvial deposits containing silts, jocds, cobbles and boulders. There are some debris fon jcpowits superimposed on the terrace near Hawk Greek as shown a,4 pr,Uably same colluvium near the base of the steep � hillside. A -eccnt flcod cn Hawk Creek has destr'syed the bridge there �`n�� �ld�r �lso�s in the form of^de�rts flows have also ` -;Fqctad the preu.

The landscaping would only have �to'' have a net relief Of approxi t l five feet because of the ma e y z..f a- 0 518 nanomcs from the sourca o! the dabris flown and the evidence their historic p<atn3. hs building envelope as defined should be at least =u fr=et r cm the base of the steep hill becauge of the potential of xi "or- snow slides down to the base. There is no evidence of ._avolanching having historically affected this site, nor was there any evidence of rock:fall or unstable slopes in this 7.:.,7.1+='diate vicinity. Tho Pitkin County floodplain maps of this portion of the Crystal River indicate that the 100 year flood boundary i very close to the top of the bank in this area; therefore, a detailed survey of the 100 -year floodplain will be necessary. Although the 100 -year flood should not overflow the bank: in this straight stretch of the Crystal River, the proposed home should to held at least 0 feet back: from the edge of the Wk: but certainly south of the previously mentioned swale. Access t� � the site was once available, but will now require tne building of a new bridge to the site. This bridge should Piave' as wide a span as feasible in this area and have a. final height of at least two feet .above present grade to allow amain _:.:ace for floods and debris flows to pass beneath. It _•.,-,.id be advisable to have this bridge designed by an arr_i.n=er- familiar with mountain flooding, rather than built by a contractor without the necessary expertise. Soils engineering should be performed at the site specific lc_vel to insure proper- foundation design. This report should include provisions .for positive drainage away from the i QmG site and a perimeter subsurface drain around the f:_,yndstion. If necessary, water for domestic use will be available by the drilling of a fairly shallow well within the c:!_ i i j i na_ envelope. Waste disposal should be available t;l'-ough the usy of a septic sy=stem and accompanying leach ti_ld in this type of permeable soil with a significant depth tQ bedrock; however, the Pitkin County Sanitation Engineer .-auld be consulted for his specific recommenda-tions, .__:pacially in view of the proximity to the Crystal River. 7is site should be a suitable one for the development of a 0.ng l e family residence, if my recommendations are f of l owed . i;; addition, I would like to be present during the staking cf the bu, lding so that final landscaping considerations 7:i be dealt with effectively at that time. please feel free -n calt..act me if there are fur-tner- questions. cincerely, encl.

We present the following review comments for your consideration regarding the referenced proposal: 1. WATER SUPPLY The geologic report of Nick Lampiris dated November 25, 1985 indicates that it should be possible to obtain a drinking water supply from a well drilled in the diluvidi material "within the building envelope" and as long as the minimum separations from the septic system are maintained, we concur with this general conclusion. A well permit has already been issued by the Division of Water Resources. 2. SEWAGE DISPOSAL It should be possible to construct a conventional onsite waste- water disposal system on this site. We do have some concern that the absorption area of the septic system be placed in such a way that it is as far from the creek and the river as is possible. As indicated in the attached correspondence, the other site factors influencing the type and design of a septic system have been evaluated last year and found to comply with Pitkin County Code. 3. OTHER ENVIRONMENTAL HEALTH CONCERNS Other concerns of this department relate to the water quality impacts an the potential of sediment being introduced into the river as a result of the bridge construction. We would suggest that the applicant develop a plan with his contractor and engineer to coincide the timing and construction activities to a period of low flow and, that the design minimize the erosion of the banks during construction. 130 South Galena Street Aspen, Colorado 81611 303/925-2020 MEMORANDUM TO: Pitkin County Planning and Zoning Commission FROM: Francis Krizmanich, Planning Office RE: B r of tz man/Cotton 1041 Geol oqi c/Floodplain Hazards Parcel ID#2729-292-00-006 DATE: July 8, 1986 REQUEST: The Applicants are requestinq Special Review approval to construct a single-family residence on property containing mapped 1041 Hazards including Geologic and Floodplain.. APPLICANT: Stephen Broitzman and Renae Cotton LOCATION: The property is located on the north side of Hawk Creek at its confluence with the Crystal River approximately two (2) miles south of Redstone. ZONING: The property is a 23 acre parcel that is zoned RS -30. It is a legal non -conforming (as to lot size) lot. ACCESS: Access to the property is via private drive from the south which will utilize a bridge to cross Hawk Creek. WATER: tater is proposed to be provided by a well. The Appli- cants have been issued a well permit by the State Division of Water Resources. SEWER: Sewage is proposed to be treated by an on-site wastewater disposal system. MAJOR ISSUES AND CONCERNS: I. Referral Agency Comments: 1. Colorado Geological Survey -- In a letter dated June 20, 1986, Jeffrey L. Hynes commented that the Colorado Geologic Survey has reviewed this application and has no objection to its approval. 2. Environmental Health Department - in a memo dated June 20, 1986 (attached) Bob Nelson submitted the following comments: The Environmental Health Department generally 1 agrees with the Applicants that it should be possible to obtain a drinking water supply from the proposed well. An on-site wastewater disposal system should be able to be constructed on this site. We do have some concern that the absorption area of the septic system be placed in such a way that it is as far from the creek and the river as is possible. Ile would also suggest that the Applicants develop a plan to coincide the timing and construction activities to a period of low flow and that the design minimize the erosion of the banks during construction. 3. Colorado Division of Wildlife - In a letter dated February 5, 1986 (attached) Kevin Wright has commented that this property lies within critical habitat, severe winter range, and production area for elk and is also adjacent to bighorn sheep summer and winter ranges. The specific building site for one single-family residence should not cause major adverse impacts to wildlife in this area if the following guidelines are adhered to: a. Buildina should be limited to the site envelope and no builc-ing should occur farther up on the ridge or along its south facing slope. b. No dogs should be allowed in order to prevent harassment to wintering animals on the ridge. C. Fencing should be restricted to the area around the dwelling and no fencing should occur along property boundaries on the ridge where there are wintering elk. 4. County Planning Engineer - In a memo dated June 19, 1986 (attached) , Tom Newland submitted the following comments: "The following recommendations of Dr. Lampiris' geologic report should be included as conditions of approval: A landscaped berm at least 5 feet high and 400 feet long in the configuration depicted on the submitted plat should be installed to prevent anv flood or debris flow from harming the dwelling unit, 2 M ' - soils engineering should be performed to insure proper foundation placement, construc- tion and drainage flow, Dr. Lampiris should be present at the staking out of the building to insure proper place- ment and configuration of the landscaping improvements. Floodplain Concerns: The building envelope has been properly located outside and above the Crystal River and Hawk Creek floodplains. I have reviewed the proposed bridge that will be used to access the dwelling unit and have found it to conform with county standards. The bridge has been designed and approved by a certified en- gineer, and the deck supports are 2 feet above the 100 year flood level." II. STAFF COMMENTS: The Applicants' property is affected by mapped 1041 Hazards including geologic, floodplain and wildlife concerns. The recommendations of Dr. Lampiris' geologic report should be made conditions of approval as noted by Tom Mewland. The recommendations of the District Wildlife Manager, Kevin Wright, should also be made condi- tions of approval to protect critical wildlife habitat. The Planning Staff also agrees with the floodplain mapping and bridge design completed by the consulting engineers. The Planning Office notes that there is a narrow band of mature vegetation (5.0-100 feet) between the existing access road and the Crystal River. We recommend that this road be shown on the site plan and that it be used to establish the setback from the river. This vegetation should be protected as it is important in maintaining bank stability. RECOMMENDATION: The Planning Office recommends that the Planning Commission recommend that the Board of County Commissioners grant 1041 Hazard Review approval of this application subject to the following conditions: 1. A landscaped berm at least 5 feet high and 400 feet long in the configuration depicted on the submitted plat should be installed to prevent any flood or debris flow from harming the dwelling unit prior to issuance of any Certificate of Occupancv. . 2.. Prior to issuance of a Building Permit, soils engineering should be performed to insure proper foundation placement, construction and drair_aae flow. 3. Dr. Lampiris should be present at the staking out of the 0 . . D C a building to insure proper placement and configuration of the landscaping improvements. 4. The bridge design over Hawk Creek as designed by Buckhorn Goetech is approved by the County Planning Engineer. Any modifications to this design shall be re -certified by a qualified professional engineer and reviewed and approved by the County Planning Engineer prior to construction. To prevent stream sedimentation and bank erosion, the bridge construction may not take place during the months of May through June. 5. To protect critical wildlife habitat: a. No dogs shall be permitted on the property. b. All buildings shall be limited to the defined building envelope. No building shall occur on the ridge or along its south facing slope. C. Fencinq shall be restricted to the area within the building envelope. No fencing shall occur along the property boundaries on the ridge where there are wintering elk. 6. The site plan shall be modified to show the road which traverses the property and this road shall be used to determine the final configuration of the building envelop to protect riparian vegetation and insure stream bank sta- bil ity. . This site plan shall be recorded with the Board's resolution of approval for this project. 7. The Applicant shall follow the Environmental Health Office's requirements for water and septic systems.

The parcel lies in the NW 1/4 of Section 29, T 10 S, R 88 W, of the Sixth P.M., within the Redstone 7 1/2 minute quadrangle, Pitkin County, Colorado. Although the parcel is large, only the western corner near the Crystal River was studied as a potential building envelope. Topographically, this site is within the older physiographic floodplain of the Crystal River and could be termed a poorly deVined terrace. The lot is heavily wooded, including large conifers. There are linear mounds associated with Hawk: Creek: to the south and the remnants of two bridges as shown on the accompanying map with an old dirt road which once connected them. Except for the linear mounds and a well defined swale as shown, the general area of the site is nearly level. The bedrock: formation in the entire' area is the Pennsylvanian --Vermian age Maroon Formation which dips roughly 00 degrees to the west on the mountainside above the site. The Maroon Formation in this area consists mostly of siltstones., sandstones, and a few conglomerate units cemented by a red, iron compound called hematite. The building envelope itself most probably lies on alluvial deposits containing silts, sords, cobbles and boulders. There are some debris fan d: -posits superimposed on the terrace near Hawk: Creek: as shown and probably some colluvium near the base of the steep hillside. A -ecent flood on Hawk: Creek: has destroyed the bridge there and older floods in the form of`debr-is flows have also .4nct.ed the area. The building envelope as shown is free of evidence of flooding but in orner to insure aafetv of the proposed home, landscaping should be affected along the southwest side of the building envelope which would deflect any floods or debris flows into the swal e already present to the north of the .site. The landscaping would only have to have a net relief of approximately five feet because of the di �-tance from the source of the debris flows and the evidence of their historic paths. The building envelope as defined should be at least 30 feet from the base of the steep hill because of the potential of minor snow slides down to the base. There is no evidence of avalanching having historically affected this site., nor was there any evidence of rock:fall or unstable slopes in this immediate vicinity. The Pitkin County floodplain maps of this portion of the Crystal River indicate that the 100 year flood boundary is very close to the top of the bank: in this area; therefore, a detailed survey of the 100 -year floodplain will be necessary. Al though the 100 -year- flood should not overflow the bank: in this straight stretch of the Crystal Fiver, the proposed home should be held at least '<_r feet back: from the edge of the bank: but certainly soUth of the previously mentioned swal e. Access to the site was once available, but will now require the building of a new bridge to the site. This bridge should have as wide a span as feasible in this area and have a final height of at least two feet above present grade to allow ample space for floods and debris flows to pass beneath. it ,-jould be advisable to have this bridge designed by an engineer familiar with mountain flooding, rather than built by :a contractor without the necessary expertise. Soils engineering should be performed at the site specific level to insure proper- foundation design. This report should include provisions for positive drainage away from the hi,mesite and a perimeter subsurface drain around the foundation. If necessary, water for domestic use will be available by the drilling of a fairly shallow well within the t,uilding envelope. Waste disposal should be available t „-ouq_h the use of a septic system and accompanying leach field in this type of permeable soil with a significant depth t_,'3 bedrock;; however, the Pitkin County Sanitation Engineer Should be consulted for his specific recommenda-tions, ;-specially in view of the proximity to the Crystal River. 7", i s site should be a Suitable one for the development of a single family residence, if my recommendations are followed. In addition, I woi:rld lik:e to be present during the staking oi-tt of the building so that final landscaping considerations c:< -:n be dealt with effectively at that time.

Ruch, Director 6060 Broadway Denver, Colorado 80216 (297-1192) Crystal River Realty Redstone, CO 81623 Dear Sir: R4,0 ?� w On January 23,1986 I observed a 23 acre parcel of land known as the Broitzman/Cotton Property, Redstone Acres, Redstone, Colorado, SE -14, NW4, Sec. 29, T10S, R88W. This land lies within critical habi- tat, severe winter range, and production area for elk and is also adjacent to bighorn sheep summer and winter ranges. Building within this area could have adverse impacts on wildlife. However, the specific building site (envelope) for 1 single family dwelling should not cause major adverse impacts to wildlife in this area if some guidelines are followed. Building should be limited to the the site envelope and no building should occur farther up on the ridge or along its south -facing slope. In addition, no dogs should be allowed in order to prevent harassment to wintering animals up on ridge as well as added stress. Any fencing should be restricted to the area around the dwelling and no fencing should occur along property boundaries on the ridge where there are wintering elk. Therefore, it is will result from proposed site if my opinion that no major construction of a single the guidelines above are cc.
