THE SUBDIVISION PROCESS In order to subdivide land in Garfield County, an Applicant is required to complete the following land use processes in the following order: 1) Sketch Plan Review Process, 2) Preliminary Plan Review Process, and 3) Final Plat Review Process. This section will briefly describe the nature of each process and provide general direction including subdivision regulation citations to a potential applicant requesting subdivision approval in Garfield County. All of the Garfield County Zoning and Subdivision Regulations are located for purchase at the Planning Department and can also be found on the World Wide Web at the following address: http://www.garfield-countv.com/building and planning/index.htm A) The Sketch Plan Review (Section 3:00 of the Subdivision Regulations) 1. Purpose The purpose of the Sketch Plan process is to allow an individual an opportunity to propose a subdivision in a "sketch" format to the Planning Department and the Garfield County Planning Commission in order to obtain a cursory review for compliance with the County's land use review documents, regulations, and policies to identify any issues that would need to be addressed if the proposed subdivision were to be pursued. 2. Applicability Any individual proposing a subdivision in Garfield County is required to complete the Sketch Plan review process as the first step in Garfield County's Subdivision process. More specifically, Garfield County defines a subdivision (Section 2:20.48) as the division of a lot, tract or parcel of land into two (2) or more lots, tracts, parcels or separate interests, or the use of any parcel of land for condominiums, apartments or other multiple -dwelling units, as further defined by Colorado state law. 3. Application / Submittal Requirements In order to apply for a Sketch Plan Review an Applicant is responsible for reviewing Section 3:09 of the Subdivision Regulations and providing enough information to the Planning Department in the application to conduct a thorough review and provide the resulting comments to the Planning Commission for their review and comments. Specifically, Section and 3:_z_1:9 of the Subdivision Regulations contain the specific information required to be submitted to the Planning Department in order to satisfy the application requirements in addition to the information requested on this application form. 4. Process / Public Meeting The Sketch Plan review process is considered a 1 -step process because the application is reviewed only by the Planning Commission at a public meeting. In order to appear before the Planning Commission, an applicant will have submitted all required application submittal requirements mentioned above to the Planning Department Staff. Once submitted, Staff will have 15 working days to review the application to determine if all the required submittal information has been submitted as required. If Staff determines that all the required information has been submitted, a letter will be sent to the applicant indicating the application has been deemed "technically complete." It is at this point Staff will also indicate when the application has been 3 • • scheduled to be reviewed before the Planning Commission and will request the applicant supply additional copies to provide the Commission for their review. If Staff determines that all the required information has not been submitted, a letter will be sent to the applicant indicating the application does not comply with the submittal requirements and therefore has determined the application to be "technically incomplete." The letter will also outline the applications deficiencies so that the applicant knows what additional information needs to be submitted. At this point, the applicant has 6 months (180 days) to provide the necessary information to the Planning Department to remedy the application so that it may be deemed technically complete. If the application has not been deemed technically complete within this time, the application will be terminated. Once the application has been deemed technically complete and a date has been established as to when the Planning Commission will review the application, Staff will conduct a land use review of the application using the County's land use regulatory documents including the Zoning Resolution, Subdivision Regulations, and the Comprehensive Plan of 2000. In addition, Staff will also consider referral comments provided from a variety of state and local agencies who may also review the application. As a result, Staff will write a Memorandum on the proposed subdivision to the Planning Commission containing the results on the land use analysis. This Memorandum will also be furnished in advance to the applicant. At the date and time set for the public meeting before the Planning Commission, Staff will present the findings in the Memorandum and the applicant will be required to present the proposed subdivision and respond to comments and questions provided by the Planning Commission. The comments provided to the Applicant by the Planning Department and the Planning Commission as a result of the Sketch Plan Process will be kept on file in the Planning Department for 1 -year from the meeting date before the Planning Commission. If an Applicant does not submit a Preliminary Plan application to the Planning Department within the 1 -year timeframe, the Sketch Plan file will be closed and the Applicant will need to reapply for a Sketch Plan review prior to a Preliminary Plan review. B) Preliminary Plan Review (Section 4:00 of the Subdivision Regulations) 1. Purpose The purpose of the Preliminary Plan review process is to conduct a thorough review of the many aspects that are associated with dividing land in Garfield County for the purposes of residential, commercial, and industrial development. This is the most intensive review step where the Building and Planning Staff, the Planning Commission, and the Board of County Commissioners (BOCC) will conduct a thorough review of all the issues associated with the proposed subdivision against the County's regulatory requirements. Ultimately, the purpose of this process is to identify all the major issues in the proposed subdivision by using the County's Zoning Resolution, Subdivision Regulations, Comprehensive Plan of 2000, as well as other state and local referral agencies that will provide comments on any issues raised in their review. This is the process that will either approve or deny the application request. 4 • • 2. Applicability Any individual proposing a subdivision in Garfield County is required to complete the Preliminary Plan review process as the second and most intensive step in Garfield County's Subdivision process. More specifically, Garfield County defines a subdivision as the division of a lot, tract or parcel of land into two (2) or more lots, tracts, parcels or separate interests, or the use of any parcel of land for condominiums, apartments or other multiple -dwelling units, as further defined by Colorado state law. 3. Application / Submittal Requirements In order to apply for a Preliminary Plan Review, an Applicant must have already completed the Sketch Plan review process addressed in Section 3:00 of the Subdivision Regulations. An applicant requesting Preliminary Plan review will be required to submit this application form, all the required submittal information contained in Sections 4:40 to 4:94 of the Subdivision Regulations as well as address all of the applicable Design and Improvement Standards in Section 9:00 of the Subdivision Regulations. In addition to the substantive submittal information related to the proposed subdivision project itself, an applicant is required to complete all the public notice requirements so that legal public hearings can be held before the Planning Commission and the BOCC which is addressed in Sections 4:20 — 4:31 of the Subdivision Regulations. 4. Process / Public Hearings The Preliminary Plan review process is considered a 2 -step process because the application is ultimately reviewed by two County decision-making entities during public hearings: the Planning Commission who makes a recommendation to the BOCC. In order to obtain dates for the public hearings before the Planning Commission and the BOCC, an applicant will have submitted all required application submittal requirements mentioned above to the Planning Department Staff. Once submitted, Staff will have 30 working days to review the application to determine if all the required submittal information has been submitted as required. If Staff determines that all the required information has been submitted, a letter will be sent to the applicant indicating the application has been deemed "technically complete." It is at this point Staff will also indicate when the application has been scheduled to be reviewed before the Planning Commission / BOCC. Additionally, Staff will provide the applicant with the notice forms to be mailed, published, and posted. If Staff determines that all the required information has not been submitted, a letter will be sent to the applicant indicating the application does not comply with the submittal requirements and therefore has determined the application to be "technically incomplete." The letter will also outline the applications deficiencies so that the 5 • • applicant knows what additional information needs to be submitted. At this point, the applicant has 6 months (180 days) to provide the necessary information to the Planning Department to remedy the application so that it may be deemed technically complete. If the application has not been deemed technically complete within this time, the application will be terminated. Once the application has been deemed technically complete and a date has been established as to when the Planning Commission / BOCC will review the application, Staff will conduct a land use review of the application using the County's land use regulatory documents including the Zoning Resolution, Subdivision Regulations, and the Comprehensive Plan of 2000. In addition, Staff will also consider referral comments provided from a variety of state and local agencies who may also review the application. As a result, Staff will write a Memorandum on the proposed subdivision to the Planning Commission / BOCC containing the results on the land use analysis. This Memorandum will also be furnished in advance to the applicant prior to the public hearings. As mentioned above, Staff makes a recommendation to the Planning Commission and the BOCC regarding the issues raised in the analysis of the proposed subdivision. The Applicant will first propose the subdivision to the Planning Commission who is responsible for making a recommendation of approval, approval with conditions, or denial to the BOCC. Next, the application will be reviewed by the BOCC during a regular public hearing. The BOCC will consider the recommendations from the Planning Staff and the Planning Commission, the information presented by the applicant, and the public. As a result, the BOCC is the final decision-making entity regarding the proposed subdivision and will either approve, approve with conditions, or deny the application. If the BOCC approves the subdivision application at the public hearing, the approval shall be valid for a period not to exceed one (1) year from the date of Board approval, or conditional approval, unless an extension of not more than one (1) year is granted by the Board prior to the expiration of the period of approval. (See the specific information provided in Section 4:34 of the Subdivision Regulations.) Following the hearing, Staff will provide a resolution signed by the BOCC which memorializes the action taken by the Board with any / all conditions which will be recorded in the Clerk and Recorder's Office. Once an applicant has Preliminary Plan approval, they are required to complete the third and final step in the County's Subdivision Process: Final Plat Review. C) Final Plat Review (Section 5:00 of the Subdivision Regulations) 1. Purpose The purpose of the Final Plat review process is to provide the applicant with a mechanism to prove to the County that all the conditions of approval required during the Preliminary Plan review process have been met / addressed to the satisfaction of the Planning Staff and the BOCC. This being the case, the chairman of the BOCC will 6 • • 'sign the Final Plat and have it recorded memorializing the subdivision approval granted by the BOCC. This is the last step in the County's subdivision process. 2. Applicability Any individual proposing a subdivision in Garfield County is required to complete the Final Plat review process as the third and last step in Garfield County's Subdivision process. More specifically, Garfield County defines a subdivision as the division of a lot, tract or parcel of land into two (2) or more lots, tracts, parcels or separate interests, or the use of any parcel of land for condominiums, apartments or other multiple -dwelling units, as further defined by Colorado state law. 3. Application / Submittal Requirements In order to apply for a Final Plat review, an Applicant must have already completed the Preliminary Plan review process addressed in Section 4:00 of the Subdivision Regulations. An applicant requesting Final Plat review will be required to submit this application form, all the required submittal information contained in Section 5:00 of the Subdivision Regulations and responses to all the conditions of approval required as part of the Preliminary Plan review process. 4. Process The Final Plat review process is considered a 1 -step process because the application is ultimately reviewed by the Building and Planning Staff and presented to the BOCC for their signature if the application satisfies all the required submittal information to the satisfaction of the Building and Planning Department. If Staff determines that all the required information has been submitted, a letter will be sent to the applicant indicating the application has been deemed "technically complete." It is at this point Staff will also indicate when the application has been scheduled to be presented to the BOCC for signature. (This is not a public hearing or meeting and therefore does not require public notice.) If Staff determines that all the required information has not been submitted, a letter will be sent to the applicant indicating the application does not comply with the submittal requirements and therefore has determined the application to be "technically incomplete." The letter will also outline the applications deficiencies so that the applicant knows what additional information needs to be submitted. Once the application has been deemed technically complete and a date has been established as to when the BOCC will review the Final Plat, Staff will review the application / Final Plat in terms of adequacy to determine if all the submittal information satisfies the Final plat requirements as well as the responses to the conditions of approval. During this review, Staff will forward the Final Plat the County Surveyor for review and a signature. In the event there are additional questions or clarification issues to be addressed, the County Surveyor will generally contact the applicant to have the plat adjusted as necessary. Once, Staff has completed the review and all required information has been submitted to the satisfaction of the Planning Department 7 • • 'and the County Surveyor has signed the Final Plat in Mylar form, it will be scheduled at the next BOCC meeting to be placed on the consent agenda with a request to authorize the Chairman of the BOCC to sign the plat. Once the Final Plat is signed, it is then recorded by the County Clerk in the Clerk and Recorder's Office for a fee of $11 for the first sheet and $10 for each additional sheet thereafter. This fee shall be paid by the applicant. This act of recording the signed Final Plat represents the completion of the Garfield County Subdivision Process. Please refer to the specific language in the Final Plat portion (Section 5:00) of the Subdivision Regulations for specific timelines and additional responsibilities required of the applicant to complete the Final Plat process. Please Note: This information presented above is to be used as a general guide for an applicant considering a subdivision in Garfield County. It is highly recommended that an applicant either purchase the Garfield County Zoning Resolution and Subdivision Regulations or access them on-line at: http://www.garfield-countv.com/buildinq and planninq/index.htm in order to ascertain all the necessary requirements for each of the three steps including Sketch Pian Review, Preliminary Plan Review, and Final Plat Review.

THE SUBDIVISION PROCESS In order to subdivide land in Garfield County, an Applicant is required to complete the following land use processes in the following order: 1) Sketch Plan Review Process, 2) Preliminary Plan Review Process, and 3) Final Plat Review Process. This section will briefly describe the nature of each process and provide general direction including subdivision regulation citations to a potential applicant requesting subdivision approval in Garfield County. All of the Garfield County Zoning and Subdivision Regulations are located for purchase at the Planning Department and can also be found on the World Wide Web at the following address: http://www.garfield-county.com/building and planning/index.htm A) The Sketch Plan Review (Section 3:00 of the Subdivision Regulations) 1.

Application / Submittal Requirements In order to apply for a Sketch Plan Review an Applicant is responsible for reviewing Section 3:00 of the Subdivision Regulations and providing enough information to the Planning Department in the application to conduct a thorough review and provide the resulting comments to the Planning Commission for their review and comments. Specifically, Section 3:30, 3:32, and 3:40 of the Subdivision Regulations contain the specific information required to be submitted to the Planning Department in order to satisfy the application requirements in addition to the information requested on this application form. 4. Process / Public Meeting The Sketch Plan review process is considered a 1 -step process because the application is reviewed only by the Planning Commission at a public meeting.

If an Applicant does not submit a Preliminary Plan application to the Planning Department within the 1 -year timeframe, the Sketch Plan file will be closed and the Applicant will need to reapply for a Sketch Plan review prior to a Preliminary Plan review. B) Preliminary Plan Review (Section 4:00 of the Subdivision Regulations) 1. Purpose The purpose of the Preliminary Plan review process is to conduct a thorough review of the many aspects that are associated with dividing land in Garfield County for the purposes of residential, commercial, and industrial development.

An applicant requesting Preliminary Plan review will be required to submit this application form, all the required submittal information contained in Sections 4:40 to 4:94 of the Subdivision Regulations as well as address all of the applicable Design and Improvement Standards in Section 9:00 of the Subdivision Regulations. In addition to the substantive submittal information related to the proposed subdivision project itself, an applicant is required to complete all the public notice requirements so that legal public hearings can be held before the Planning Commission and the BOCC which is addressed in Sections 4:20 — 4:31 of the Subdivision Regulations. 4. Process / Public Hearings The Preliminary Plan review process is considered a 2 -step process because the application is ultimately reviewed by two County decision-making entities during public hearings: the Planning Commission who makes a recommendation to the BOCC. In order to obtain dates for the public hearings before the Planning Commission and the BOCC, an applicant will have submitted all required application submittal requirements mentioned above to the Planning Department Staff. Once submitted, Staff will have 30 working days to review the application to determine if all the required submittal information has been submitted as required.

C) Final Plat Review (Section 5:00 of the Subdivision Regulations) 1. Purpose The purpose of the Final Plat review process is to provide the applicant with a mechanism to prove to the County that all the conditions of approval required during the Preliminary Plan review process have been met / addressed to the satisfaction of the Planning Staff and the BOCC.

Process The Final Plat review process is considered a 1 -step process because the application is ultimately reviewed by the Building and Planning Staff and presented to the BOCC for their signature if the application satisfies all the required submittal information to the satisfaction of the Building and Planning Department. • • If Staff determines that all the required information has been submitted, a letter will be sent to the applicant indicating the application has been deemed "technically complete." It is at this point Staff will also indicate when the application has been scheduled to be presented to the BOCC for signature. (This is not a public hearing or meeting and therefore does not require public notice.) If Staff determines that all the required information has not been submitted, a letter will be sent to the applicant indicating the application does not comply with the submittal requirements and therefore has determined the application to be "technically incomplete." The letter will also outline the applications deficiencies so that the applicant knows what additional information needs to be submitted. Once the application has been deemed technically complete and a date has been established as to when the BOCC will review the Final Plat, Staff will review the application / Final Plat in terms of adequacy to determine if all the submittal information satisfies the Final plat requirements as well as the responses to the conditions of approval. During this review, Staff will forward the Final Plat the County Surveyor for review and a signature. In the event there are additional questions or clarification issues to be addressed, the County Surveyor will generally contact the applicant to have the plat adjusted as necessary. Once, Staff has completed the review and all required information has been submitted to the satisfaction of the Planning Department and the County Surveyor has signed the Final Plat in Mylar form, it will be scheduled at the next BOCC meeting to be placed on the consent agenda with a request to authorize the Chairman of the BOCC to sign the plat. Once the Final Plat is signed, it is then recorded by the County Clerk in the Clerk and Recorder's Office for a fee of $11 for the first sheet and $10 for each additional sheet thereafter. This fee shall be paid by the applicant. This act of recording the signed Final Plat represents the completion of the Garfield County Subdivision Process. Please refer to the specific language in the Final Plat portion (Section 5:00) of the Subdivision Regulations for specific timelines and additional responsibilities required of the applicant to complete the Final Plat process. Please Note: This information presented above is to be used as a general guide for an applicant considering a subdivision in Garfield County. It is highly recommended that an applicant either purchase the Garfield County Zoning Resolution and Subdivision Regulations or access them on-line at: http://www.garfield-countv.com/buildinq and planning/index.htm in order to ascertain all the necessary requirements for each of the three steps including Sketch Plan Review, Preliminary Plan Review, and Final Plat Review. I have read the statements above and have provided the required attached information which is correct and accurate to the best of my knowledge.

In preparing this application I have reviewed and addressed each of the items of concern expressed in your letter dated June 24, 2003. The first item relates to requirements of a Cluster Housing Project and as it is my understanding the submittal process prefers Cluster Housing information be provided at preliminary plan stage please consider this application under the normal requirements. The other items of concern are addressed as follows. 1. Section 3.32(E) is now met and lots are indicated on the contour plat. 2. Section 3.32(F) has been addressed on the plat as required. 3. Section 3.32(G) requires a description of any natural or man-made features bordering on or within the development which may require buffering or screening, particularly the 100 year floodplain of any major drainages. There are none to be described that are within the boundaries of this project. • 4. Each of the 2 Acre lots contain a minimum building area of 1 acre that has less than 40% slope. 5. Wastewater will be handled through ISDS on each lot and a registered professional engineer when required by regulations will design each system. 6. The concern of lot slopes is not justified with this project and a site visit will remove this issue of concern. Preparation of a 2 foot contour plat is currently being prepared which will be included as part of the preliminary plat application. Pursuant to Sketch Plan requirements 3:32-B attachment #1 is provided. Pursuant to Sketch Plan requirements 3:32-C attachment #2 is provided. Pursuant to Sketch Plan requirements 3:32-I attachment #3 is provided. The remaining items required for section 3:32 are indicated on the plans provided herewith for your review and consideration.

This deep, well drained, sloping soil is on fans and high terraces (fig. 4). Elevation ranges from 5,100 to 6,200 feet. This soil formed in highly saline alluvium derived from sand- stone and shale. The average annual precipitation is about 12 inches, the average annual air temperature is about 48 degrees F, and the average frost -free period is about 120 days. Typically, the surface layer is strongly .alkaline or very strongly alkaline, pale brown loam about 3 inches thick. The subsoil is brown silty clay loam about 14 inches thick. The substratum is light brown or brown silty clay loam to a depth of 60 inches. Included with this soil in mapping are small areas of Limon, Kim, Heldt, and Wenn soils. Also included are some soils that are high in silt. Permeability is very slow, and available water capacity is moderate. Effective rooting depth is 60 inches or more. Organic matter content of the surface layer is low. Surface runoff is medium, and the erosion hazard is moderate. This soil is used manly for wildlife habitat, limited grazing, and some irrigated farming. Irrigated crops produce very poorly because the soil takes water in very slowly and is droughty. Leaching is needed to remove excess salts if this soil is to be irrioat- ed. Soil amendments containing sulphur are helpful in :teaching the salt. The native vegetation on this soil is mainly saitgrass, alkali sacaton, and greasewocd. When range condition deteriorates, forbs and shrubs increase. Properly managing grazing maintains and im- proves range condition. Seeding improves range in poor condition. Western wheatgrass, alkali sacaton, and tall wheatgrass are suitable for seeding. Preparing a seedbed and drilling the. seed are good practices. Irrigat- ing new seedings is necessary for successful establish- ment.

This soil is in ca.p .bility subclass Vlls, iiricat2d and nonirrigated. • • 51-01ns=y loam, 6 to 12 percent slopes. This deep, we!i drained, moderately sloping to rolling soil is on allu- vial fans and s!des of valleys. Elevation ranges from 5,000 to 6,500 feet. This soil formed in alluvium derived from sandstone and shale. The average annual precipita- tion is about 14 inches, the average annual air tempera- ture is about 45 degrees F, and the frost free period is about 125 days. Typically, the surface layer is grayish brown loam about 12 inches thick. The subsoil is grayish brown and light gray sandy clay loam about 21 inches thick. The substratum is light gray gravelly sandy clay loam and very gravelly sandy loam to a depth of 60 inches. Included with this soil in mapping are small areas of He!dt. Potts. and Kim soils that have slopes of 6 to 12 percent. These areas make up 5 to 15 percent of the map unit. Permeability is moderate, and available water capacity is moderate. Effective rooting depth is 60 inches or more. Surface runoff is medium, and the erosion hazard is moderate. This soil is used mainly for irrigated hay, fruits, and grazing. Grass -legume mixtures and apples, peaches: and apricots are grown. This soil is irrigated by furrows and flooding. Sprinklers are also suitable. Drop structures in irrigation ditches help to control water and prevent excessive ditch ero- sion. Keeping a grass or legume cover on this soil at Fast three-fourths of the time controls erosion. The native vegetation on this soil is mainly wheat - grass, needleandthread, and sagebrush. When range condition deteriorates, forbs and shrubs increase. When the range is in poor condition, undesira- ble weeds and annual plants are numerous. Properly managing grazing maintains and improves range condi- tion. Reducing brush improves the range. Seeding im- proves range in poor condition. Crested wheatgrass, western wheatgrass, and Russian wildrye are suitable for seeding. Preparing a seedbed and drilling the seed are good practices. Cottontail rabbit, squirrel, pheasant, and some mule deer find habitat on this soil. Community development and recreation are limited by steep slopes and low strength. This soil is in capability subclass IVe, irrigated and nonirrigated. • • 67 — T or r iorthents-tock outcrop complex, steep. This broadly defined unit consists of exposed sandstone and shale bedrock and stony soils that are shallow to moderately. deep over sandstone and shale and stony basaltic alluvium. Areas of this complex occur throughout the survey area. The soils and outcrops are moderately steep to very steep. Slope ranges from 15 to 70 percent. Torriorthents make up about 60 percent of this com- plex, and Rock outcrop makes up 25 percent. The Tor- riorthents are on foothills and mountainsides below the Rock outcrop. Torriorthents are generally clayey to loamy and con- tain variable amounts of gravel, cobbles, and stones. The surface is normally covered with stones weathered from the higher -lying Rock outcrop. South of the Colora- do River, stones and cobbles of basalt are on the sur- face. The Rock outcrop is mainly Mesa Verde sandstone and Wasatch shale. Some areas are covered with basal- tic boulders and stones. Small areas of limestone out- crops and exposed gypsum are in the eastern part of the survey area. Included in mapping are small isolated areas of Ilde- fonso, Lazear, Ansari, Gaynor, Tridell, and Nihill soils. These intermittent areas make up 10 to 15 percent of this map unit. This complex is used for limited grazing, wildlife habi- tat, and recreation. Because of the stones on the surface, the Rock out- crop, and the steep slope, this complex is unsuited to crops. The native vegetation includes wheatgrass, bluegrass, Indian ricegrass, needlegr ass, bitter brush, sagebrush, mountainmahogany and an o✓erstory of pinyon and juni- per. The vegetation should be managed to maintain wood production and limited grazing Selectively thinning the pinyon and juniper improves grazing and provides fire- wood and posts. Steep slopes, moderate to severe ero- sion hazard, and slow regrowth of trees affect harvesting and management. Most of this complex is a prune wintering area for deer. Rabbits, coyote, and a few elk also find food and cover on this complex. Community development is limited by the Rock out- crop, steep slopes, and stoniness. These limitations car be overcome by appropriate design and construction. This complex is in capability subclass Vile, nonirrigat- ed. June 24, 2003 Timothy A. Thulson Balcomb & Green, P.C., Attorneys at Law P.O. Drawer 790 818 Colorado Avenue Glenwood Springs, Colorado 81602 RE: Mamm Creek Commons Sketch Plan Dear Mr. Thulson: Garfield Cotinty BUILDING & PLANNING DEPARTMENT Thank you for the Cluster Sketch Plan application you submitted to this office on June 6, 2003 on behalf of Jimmy M. Sills entitled "Mamm Creek Commons." The purpose of this letter is to inform you that the Garfield County Building and Planning Department needs additional information in order to begin reviewing your application. Your timeliness in providing this information will expedite our ability to place your application the regular Garfield County Planning Commission agenda. As you are aware, yield plans are normally decided at preliminary plan stage, although there is nothing precluding an applicant from effectively proposing a yield and cluster plan at the sketch plan stage (pursuant to Section 4:11 of the Subdivision regulations) if the applicant has also provided "detailed site information for lot configuration analysis at that point." Given this statement, your present application does not include enough information to constitute a complete sketch plan application if you desire a "yield analysis" as part of sketch plan. Therefore, please respond more specifically to the following items. 1. Section 3:32(E) of the subdivision regulations requires that proposed sketch plan(s) shall contain topography of the proposed subdivision showing, at a minimum, five (5) foot contours for terrain with an overall average slope of less than twenty percent (20%) and at a minimum ten foot (10') contours for terrain with an overall average slope of over twenty percent (20%), contours developed by interpolation of U.S.G.S. quadrangle contours are acceptable. The sketch plan submitted to this office contains a correctly scaled graphic representation of the property with topography as it currently exists. However, neither the proposed conventional sketch plan nor the proposed cluster sketch plan contains any topography. This is critical information required to determine a practical and realistic "Yield Analysis" which is the 108 8th Street, Suite 201, Glenwood Springs, Colorado 81601 (970) 945-8212 (970) 285-7972 Fax: (970) 384-3470 • • foundation for the cluster approach to subdivision. Please resubmit both the conventional and cluster sketch plans that include topography pursuant to language in Section 3:32(E) of the subdivision regulations. 2. Section 332 (F) requires that general location and dimensions of all existing and proposed lots, streets, alleys, easements, road rights-of-way, irrigation ditches and water courses within and immediately adjacent to the proposed development. Neither the Yield Plan nor the cluster plan contains any dimensions or lot areas for each lot. 3. Section 3:32(G) of the subdivision regulations requires a description of any natural or man- made features bordering on or within the development which may require buffering or screening, particularly the one hundred (100) year floodplain of any major drainages. Neither the proposed conventional sketch plan nor the proposed cluster sketch plan contains any information regarding this standard. Please resubmit both the conventional and cluster sketch plans that this information. 4. Your sketch plan shows a conventional "yield" of 27 lots based on the A/R/RD zoning allowing for a minimum lot size of 2 acres. However, it is not possible to determine a realistic "yield" of how many lots would be actually allowed based on the limited information related to the evident slopes that exist on the property and the required acreage required for roads and infrastructure. More specifically, because the conventional or cluster sketch plans do not contain any topography, it is impossible to determine if the proposed lot sizes and their associated building envelopes comply with slope and lot size regulations set forth in Sections 5.04.01 and 5.04.02 of the Zoning Resolution of 1978, as amended. Please review the following language: 5.04.01 Lot Slope Determinations: In determining lot slopes for use in establishing minimum lot area requirements and buildable area, existing and proposed lots of less than two (2) acres shall be calculated on an individual lot basis. Contour intervals of five (5) feet or less shall be used to make this determination. For lots of two (2) or more acres in size and tracts of land proposed for other methods of development wherein creation of individual lots within said tract is not anticipated, the determination of lot slope shall be made utilizing available topographic maps. 5.04.02 Development Limitations Based on Lot Slope: (1) Lot Size Less Than 1 Acre: Land with original and undisturbed slope in excess of forty percent (40%) shall not be credited toward lot area in determining whether a lot meets the minimum lot area requirements set forth in the zone district regulations; however, a smaller building envelope may be approved by the Board, as a Special Use permit, after review. (2) Lot Size 1 Acre or Greater: Such lots shall have a minimum building envelope of 1 acre in an area that has less than forty percent (40%) slopes; however, a smaller building envelope may be approved by the Board after review ofthe following which shall be submitted by the applicant: (A) A soil land foundation investigation prepared by a registered, professional engineer. (B) A topographic survey with contour intervals of not more than two (2) feet. L • (C) A site grading and drainage plan prepared by a register, professional engineer. (D) A detailed plan of retaining walls or cuts, and fills in excess of five (5) feet. (E) A detailed revegetation plan. All of the above shall show the minimum building envelope size for each lot and shall provide evidence that all structures and facilities can be built within such building envelope area so as not to disturb any forty percent (40%) slope area. The following shall be conditions of any approval: (A) Foundations shall be designed by and bear the seal of a registered, professional engineer. (B) All final plans required to be submitted by a professional engineer shall be approved in their final form and shall bear the seal of such registered, professional engineer. For all lots: Driveways, access ways and access easements within the development and on the property of developer shall have a maximum grade offourteen percent (14%). (A. 94-046) (3) Ultimately, the conventional sketch plan analysis should prove compliance with these regulations so that a realistic "yield" can be determined. Please review the language above and provide this office with the required analysis showing that each proposed 2 acre lot contains a building envelope of 1 acre in an area that has less than forty percent (40%) slopes. In other words, this exercise truly allows for more accurate determination of how many lots truly could be created ("yield") under conventional two acre zoning. This is critical to determine the bonus lots possible. 5. While the application indicates wastewater will be handled through ISDS on each lot, it is apparent that the significance of steep slopes on the property and the proposed lot configuration proposes ISDS siting issues. Additionally, the sketch plan proposes lots that are less than 1 acre which is not allowed. Please review the sewage disposal regulations below so that your conventional sketch is more appropriately designed so that Staff can more accurately determine a base yield. 5.04.03 Lot Area Restrictions Based on Sewage Disposal Method to be Employed: (1) The following minimum standards shall apply and be used in conjunction with the Garfield County Individual Sewage Disposal System Regulations in all zone districts, and the following table shall be used to determine whether various types of disposal are allowable on various lot areas: TYPE OF DISPOSAL LOT AREA Less than 1-2 acres 1 acre Cesspool (FN1) no no Anaerobic no (FN7) yes (FN4) Disposal On Lot (FN2) over 2 acres no yes • • Aerobic no (FN7) yes (FN4) yes Treatment on Lot (FN3) Treatment Off yes yes yes Lot - Nondis- charging (FN5) Treatment Off yes yes yes Lot - Discharging(FN6) When all other means of disposal are deemed unacceptable, vaults, privies and chemical toilets may be allowable for temporary use or permanent use when approved by the Environmental Health Officer pursuant to the Garfield County Individual Sewage Disposal Systems Regulations and applicable provisions of State Law. In addition, please keep in mind that the Colorado State Board of Health's "Guidelines on Individual Sewage Disposal Systems (Revised 2000) require that no ISDS can be permitted on slopes of greater that 30% unless designed by a registered professional engineer and approved by the local board of health. 6. In addition to lot slope discussed above, it is apparent several of the proposed lots on the conventional yield sketch have lot frontages of less than 25 linear feet. This also jeopardizes the ability to determine a correct yield based on a lot design that does not conform to underlying zoning as required in Section 5.01.05 of the Zoning Resolution of 1978, as amended. Please feel free to call me if you have any questions regarding these requirements.

The 47 acre property which is the subject of this application contains a great deal of significant slope constraints of 40% or steeper slopes. As a result, the number of allowed lots plus a bonus lot will be much lower than this calculation based on Staff's limited analysis of the slopes present on the property. • THE MAMM CREEK COMMONS A CLUSTER HOUSING PROJECT SKETCH PLAN SUMMITTAL June 6, 2003 • • Jimmy Sills 45705 Hwy 6&24 Glenwood Springs CO 81601 Phone (970) 947-9511 Fax (970) 947-9233 June 6, 2003 Mr. Mark Bean Garfield County Planning Department 108 8th Street Suite 201 Glenwood Springs, CO. 81602 Re: Mamm Creek Commons Sketch Plan Dear Mr. Bean, Enclosed herewith please find the Subdivision Application Form and related information for Sketch Plan review of The Mamm Creek Commons project located South of the Garfield County Airport off County Road 319. This project is being proposed based on the Clustering Initiative Amendment recently adopted by Garfield County. In an attempt to address the concerns of a Cluster Option analysis this submittal includes additional information that would not normally be presented at this time. A Sketch Yield Plan is included in order to allow for a Yield Analysis to be undertaken by staff and although not a great deal of time was spent in creating this Yield Plan it is sufficient to identify the benefits of the newly adopted Clustering Initiative. The project is situated on 47.20 acres and designed for 27 single-family 1 -acre lots. There will be a central water system and ISDS as allowed with -in the Clustering Initiative Amendment. Care has been taken in the design of the proposed lots including the location and size of lot driveways being adequate to incorporate installation of an Infiltration System. Of course, final determination will be based on percolation tests. The natural terrain has also been considered and the design of lots and building envelopes has received great attention in order to protect and preserve the natural features. Mamm Creek Commons/Sketch Plan Page 1 • • As the Subdivision process continues and the Rules and Regulations of the Homeowners Association are created, this project will not allow the keeping of "hoofed" animals on any lot or Commons Lands. The H.O.A. will be the entity that owns and will be responsible for the Commons Lands and also the maintenance of all utilities, roads, and drives located with -in the Commons Lands. The rules and regulations for the Common or Greenbelt Lands of this project will include protection from future development of the natural rock bluffs and preservation of the cedar tree areas in order to provide buffering of the residential building envelopes. Allowable structures with -in the Common Lands will be limited to requirements of the project such as pump houses and other common use buildings as determined beneficial by the H.O.A. and approved by a majority of the lot owners. This entity will also be responsible for weed control and erosion management as may be required from time to time. However, the primary goal in creating these lands shall always be to retain the natural landscape. Improvements shall be limited to footpaths or structures that are a benefit to the public and the homeowner's with -in the development. In addition with the Common Lands controlled by the H.O.A. each lot will include Private Natural Lands that will be protected from fencing and other man made features through the rules and regulations of the project. Building envelopes are designated which will identify the areas of fencing and development allowed on each lot in order to minimize the impact on wildlife and future protect the natural features of the lands. Pursuant to Sketch Plan requirements 3 :32-B attachment #1 is provided. Pursuant to Sketch Plan requirements 3:32-C attachment #2 is provided. Pursuant to Sketch Plan requirements 3:32-I attachment #3 is provided. The remaining items required for section 3:32 are indicated on the plans provided herewith for your review and consideration. Supplemental Information required pursuant to section 3:40 is included herewith as attachment #4. The County adoption of the Clustering Initiative Amendment provides the opportunity to create projects that are land friendly and the efforts required to achieve this opportunity should be, and are greatly appreciated. Current zoning that Mamm Creek Commons/Sketch Plan Page 2 • • allows for 2 -acre parcels often results in abusive land use with little control or regulations of the 23 lots that could be created. The additional 4 lots being requested provides funds that can be used to provide a central water system beneficial to fire issues, improve internal roads, and at the same time preserve the natural land features. This Sketch Plan is submitted indicating 27 lots with the knowledge that the actual number of permitted lots is subject to change and will be determined by Staff and the Planning Commission pursuant to section 4.11 of the Preliminary Plan application. Rather than waiting until the Preliminary Plan submittal it was decided to identify this project as a Cluster Housing project now in hopes of receiving comments that will assist in the design and presentation of the Preliminary Plan. For your review the following information is provided to indicate the approximate acreage of the proposed land use: Total acreage included in proposal 47.20 Acres Dedicated as Common Natural Lands (Common Open Space) Dedicated as Private Natural Lands (Greenbelt) Allowed for private fencing and use Allowed for building and improvements 20.20 Acres 42.8% 15.42 Acres 32.7% 8.50 Acres 18.0% 3.08 Acres 6.5% Total Common Open Space/Greenbelt 35.62 Acres 75.5% We look forward to receiving your comments and suggestions regarding this sketch plan proposal and hope the information provided is adequate for scheduling review at the July Planning Commission meeting.

This deep, well drained, sloping soil is on fans and high terraces (fig. 4). Elevation ranges from 5,100 to 6,200 feet. This soil formed in highly saline alluvium derived from sand- stone and shale. The average annual precipitation is about 12 inches, the average annual air temperature is about 48 degrees F, and the average frost -free period is about 120 days. Typically, the surface layer is strongly .alkaline or very strongly alkaline, pale brown loam about 3 inches thick. The subsoil is brown silty clay loam about 14 inches thick. The substratum is light brown or brown silty clay loam to a depth of 60 inches. Included with this soil in mapping are small areas of Limon, Kim, Heldt, and Wann soils. Also included are some soils that are high in silt. Permeability is very slow, and available water capacity is moderate. Effective rooting depth is 60 inches or more. Organic matter content of the surface layer is low. Surface runoff is medium, and the erosion hazard is moderate. This soil is used mainly for wildlife habitat, limited grazing, and some irrigated farming. Irrigated crops produce very poorly because the soil takes water in very slowly and is droughty. Leaching is needed to remove excess salts if this soil is to be irrigat- ed. Soil amendments containing sulphur are helpful in leaching the salt. The native vegetation on this soil is mainly saltgrass, alkali sacaton, and greasewood. When range condition deteriorates, forbs and shrubs increase. Properly managing grazing maintains and im- proves range condition. Seeding improves range in poor condition. Western wheatgrass, alkali sacaton, and tall wheatgrass are suitable for seeding. Preparing a seedbed and drilling the seed are good practices. Irrigat- ing new seedings is necessary for successful establish- ment. Reducing brush improves the range •if the grass understory is adequate. Cottontail rabbit and pl;b:-. 1 1t find shelter on this soil if they can obtain food in surrounding areas. Use of this soil for sanitary facilities, for community deveiccme; t, and as a source of construction material is limited by the high shrink -swell potential, slow permeabil- ity, clayey textures, and salinity. This soil is in capability subclass Vlls, irrigated and nonirrigated. • • 51—Qiney loam, 6 to 12 percent slopes. This deep, well drained, moderately sloping to rolling_ soil is on allu- vial fans and sides of valleys. Elevation ranges from 5,000 to 6,500 feet. This soil formed in alluvium derived from sandstone and shale. The average annual precipita- tion is about 14 inches, the average annual air tempera- ture is about 48 degrees F, and the frost -free period is about 125 days. Typically, the surface layer is grayish brown loam about 12 inches thick. The subsoil is grayish brown and light gray sandy clay loam about 21 inches thick. The substratum is Tight gray gravelly sandy clay loam and very gravelly sandy loam to a depth of 60 inches. Included with this soil in mapping are small areas of Heidi. Potts. and Kim soils that have slopes of 6 to 12 percent. These areas make up 5 to 15 percent of the map unit. Permeability is moderate, and available water capacity is moderate. Effective rooting- depth is 60 inches or more. Surface runoff is medium, and the erosion hazard is moderate. This soil is used mainly for irrigated hay, fruits, and grazing. Grass -legume mixtures and apples, peaches, and apricots are grown. This soil is irrigated by furrows and flooding. Sprinklers are also suitable. Drop structures in irrigation ditches help to control water and prevent excessive ditch ero- sion. Keeping a grass or legume cover on this soil at least three-fourths of the time controls erosion. The native vegetation on this soil is mainly wheat - grass, need!eandthread, and sagebrush. When range condition deteriorates, forbs and shrubs increase. When the range is in poor condition, undesira- ble weeds and annual plants are numerous. Properly managing grazing maintains and improves range condi- tion. Reducing brush improves the range. Seeding im- proves range in poor condition. Crested wheatgrass, western wheatgrass, and Russian wildrye are suitable for seeding. Preparing a seedbed and drilling the seed are good practices. Cottontail rabbit, squirrel, pheasant, and some mule deer find habitat on this soil. Community development and recreation are limited by steep slopes and low strength. This soil is in capability subclass IVe, irrigated and nonirrigated. • 67—Torriorthents-Sock outcrop complex, steep. This broadly defined unit consists of exposed sandstone and shale bedrock and stony soils that are shallow to moderately deep over sandstone and shale and stony basaltic alluvium. Areas of this complex occur throughout the survey area. The soils and outcrops are moderately steep to very steep. Slope ranges from 15 to 70 percent. Torriorthents make up about 60 percent of this com- plex, and Rock outcrop makes up 25 percent. The Tor- riorthents are on foothills and mountainsides below the Rock outcrop. Torriorthents are generally clayey to loamy and con- tain variable amounts of gravel, cobbles, and stones. The surface is normally covered with stones weathered from the higher -lying Rock outcrop. South of the Colora- do River, stones and cobbles of basalt are on the sur- face. The Rock outcrop is mainly Mesa Verde sandstone and Wasatch shale. Some areas are covered with basal- tic boulders and stones. Small areas of limestone out- crops and exposed gypsum are in the eastern part of the survey area. Included in mapping are small isolated areas of Ilde- fonsc, Lazear, Ansari, Gaynor, Tridell, and Nihill soils. These intermittent areas make up 10 to 15 percent of this map unit. This complex is used for limited grazing, wildlife habi- tat, and recreation. Because of the stones on the surface, the Rock out- crop, and the steep slope, this complex is unsuited to crops. The native vegetation includes wheatgrass, bluegrass, Indian ricegrass, needlegrass, bitterbrush, sagebrush, mountainmahogany and an overstory of pinyon and juni- per. The vegetation should be managed to maintain wood production and limited grazing. Selectively thinning the pinyon and juniper improves grazing and provides fire- wood and posts. Steep slopes, moderate to severe ero- sion hazard, and slow regrowth of trees affect harvesting and management. Most of this complex is a prime wintering area for deer. Rabbits, coyote, and a few elk also find food and cover on this complex. Community development is limited by the Rock out- crop, steep slopes, and stoniness. These limitations can be overcome by appropriate design and construction. This complex is in capability subclass Vile, nonirrigat- ed. $4d4r. rib d et.

I would like to note that this is the Preliminary Plan and many issues brought up, though valid, will be addressed at Final Plat, This is allowed according to Section 4:41 of the Garfield County Regulations stating that detailed construction, engineering and design plans at the time of Final Plat submittal. 1 have separated your comments as we discussed in out meeting into items that should be addressed as contingent to the Preliminary Plat approval and comments that will be addressed at time of Final Plat. This project is proposed as two phases. The first phase consists of Lots 1-12 located off of Grass Mesa Road. Phase 1 includes the access drives, grading and drainage facilities, water system, and 1SDS's for these lots. Phase 2 is defined as Lots 13-24 located in the southern portion of the site. These lots gain access from the new road tying into County Road 319 (CR 319). COMMENTS REGARDING PRELIMINARY PLAT CONTINGENCIES Drainage Report: There are no real disagreements with the comments provided. The drainage report will be revised to address the concerns. 1. How were the rainfall depths determined for the 25 -year and 100 -year storms? 2. What percent density of vegetative ground cover was used for the CN calculations? Assumptions should be consistent with the Vegetation Report prepared for the project. 3. What type of vegetation was assumed for each sub -basin? Assumptions should be consistent with the Vegetation Report prepared for the project. 4. The report states that detention will not be required for this site since developed peak flows are approximately equal to existing peak flows.

Sanitary Sewer System: ▪ General response to Sanitary Sewer System: Each lot will have a separate ISDS. Each lot with soils identified by the Geotechnical report with percolation tests between 60 and 120 minutes per inch will require lvlamm Creek Commons Page 2 of 13 FROM :MountainCrossEng,Inc FAX NO. :9709455559 Jul. 13 2004 03:21PM P3 additional geotechnical investigation and an engineered ISDS. This is allowcd by the Colorado Department of Public Health (CDPH) and Garfield County regulations. Engineered systems may include, but not limited to, mound and dosing systems. Location of the combined ISDS systems has yet to be finalized, however, leach fields will be within Common Open Space near the residences being served. The individual lots that may be combined will be addressed at the time of Building permit. 1. Using a leaching type of ISDS will not be an acceptable wastewater disposal alternative for lots 9 through 24 based on the percolation test results and the depth to bedrock reported by 14PGeotech in the report dated March 10, 2004. What type of engineered systems will be used instead? ▪ It is anticipated that a suitable location ffr an ISDS will be located for each lot. If an adequate location within the individual lots cannot be found piping effluent from the residence to a location within nearby Common Open Space suitable for an ISDS leach field may be required. 2. Will the ISDS system be congruent with the diversions and consumptive use calculations for water use? • No, the ISDS's will be designed according to CDPH guidelines. 3. Will the Board of Health approve ISDS for the site considering the percolation rates, land slopes, depth to bedrock, etc? • The Board of Health will approve engineered systems for the areas of slower percolation tests and unfavorable terrain assuming the engineered system meets their requirements. The designs will be completed at the time of Building Permit. 4. The sewer report estimates 140 gpd as average daily sewage. This is much less than estimated in the water use calculations. Supporting calculations and assumptions should be submitted. • The average daily sewage for each residence is based on the CDPH guidelines. ISDS design will be completed at the time of Building Permit and follow CDPH guidelines for sizing. 5. The sewer report proposes that two single family homes will utilize one ISDS system. Which lots are to be paired up? Where will these systems be located? What conditions, covenants, or restrictions will be implemented for these communal systems? Refer to General response to Sanitary Sewer System above. 6. A proposed management plan for the operation and maintenance of the ISDS needs to be provided. • The operation and maintenance of the ISDS systems will be provided with the design and implementation of each system. The Home Owners Association is responsible for defining responsibilities of the ISDS's. These responsibilities will include operation and maintenance of the facilities. Road and Traffic Report: 1. Off-site road impacts and traffic study is absent. Does this need to be provided? • A traffic study will be prepared and submitted as a condition of Preliminary Plan approval.

How was the 30,000 gallon storage volume determined? • The 30,000 gallon storage tank is sized to provide service to Lots 1-12 with the necessary fire protection. All houses will have fire sprinkler systems. Support information will be provided as part of the contingency of approval. 2. How were the water line sizes determined? • The water lines were sized to provide adequate water supply to Lots 1-12. Support information will be provided as part of the contingency of approval. 3. Has the fire district reviewed the hydrant spacing? What parameters are proposed for hydrant locations? Lots 6, 7, and 8 appear to need a fire hydrant. • We are awaiting comments and suggestions from the fire district. Any comments will be addressed in a fashion to satisfy the fire district, the county and the owner. MU -2 • General response to MU -2 comments: This sheet is part of Phase 2 of the proposed Preliminary Plan. The issues below will be negotiated between the Review Engineer, the County, the Fire District, and the Owner to satisfactorily resolve these issues. These issues will be resolved during the continuance period for Phase 2. 1. How was the 30,000 gallon storage volume determined? • The 30,000 gallon storage tank is sized to provide service to Lots 13-24 with the necessary fire protection. All houses will have fire sprinkler systems. Support information will be provided. 2. How were the water line sizes determined? • The were size to provide adequate water supply to Lots 13-24. Support information willbe provided. 3. The valves as shown would allow water from the booster pump to fill Tank #2 directly, without going through the proposed Pump House. Assuming that Tank #2 will be similar in design to Tank #1 and not a pressure tank, there would be no pressure regulation. The 6" line from Phase 1 will likely need to go into the pump house first. Would this cause a revision to the layout and drainage of the #2 Tank/Pump House arrangements? • The booster pump near the south tank is to provide pressure to the upper lots. 4. Has the fire district reviewed the hydrant spacing? What parameters are proposed for hydrant locations? Lots 14, 15, and 24 appear to need a fire hydrant. • We are awaiting comments and suggestions from the fire district. Any comments will be addressed in a fashion to satisfy the fire district, the county and the owner. Mamm Creek Commons Page 4 of 13 FROM :MountainCrossEng,Inc FAX NO. :970945555B Jul. 13 2004 03:22PM P5 MU -3 1. The pumps are proposed for 50 gpm at 180 TDH. What are the fire flow requirements? A water model should be performed showing that the required fire flow will operate at required pressures. ■ Support information will be provided. COMMENTS TO BE ADDRESSED AT FINAL PLAT Soils Report: 1. A note should be included on the plat requiring that a site specific geotech study for each lot be prepared. ■ A note will be added to the Final Plat indicating each site will require a site specific geotechnical study for foundations and ISDS systems. 2. A note should be included on the plat considering the rock fall runout of Lot 24. ■ A note will -be added. Dry Utilities: 1. It is unclear whether or not natural gas is planned for the site. a The Dry Utility Report states that it is not cost effective to serve the site with natural gas. Therefore, it is currently not planned to serve the site with natural gas. Plan Sheet Sets: Preliminary Plat: 1. No drainage easements arc shown for concentrated flows across lots. ■ Drainage casements will be provided on the Final Plat. 2. No utility easements are shown for utilities within Lots 1, 2, 3, and 4. ■ All necessary utility easements will be provided on the Final Plat. General Comments: 1. How will lots 11 and 24 get reasonable access? ■ These lots have access to the lot line as required by the Garfield County Cluster Housing regulations. Access within the lot will be addressed at time of Building Permit. 2. Where will the building envelopes be located? ▪ All building envelopes will be provided on the Final Plat. GR -I 1. Erosion control will be necessary for the concentrated flows from the warped cross section. • The proposed road will be altered to avoid concentrated flows across the road. The downstream side of the road will be protected from erosion with erosion control fabric until vegetation is reclaimed. 2. Silt- bales should be placed in the roadside ditch on the south side of Grass Mesa Road. • Silt bales will be placed on a regular interval as necessary in the roadside ditch on the south side of Grass Mesa Road. Mamm Creek Commons Page 5 of 13 FROM :Mounta inCrossEng. Inc FAX NO. :9709455558 Jul. 13 2004 03:22PM PE 3. Silt fencing should also be considered on areas for Lots 3, 4, and 5 and their access. ■ The disturbed areas within Lots downstream side until vegetation condition. the east and south sides of the disturbed 3, 4, and 5 will be bounded on the has been restored to preconstruction GR -2 ■ General response to GR -2 comments: This sheet is predominately Phase 2 of the proposed Preliminary Plan. The issues below will be negotiated between the Review Engineer, the County, the Fire District, and the Owner to satisfactorily resolve these issues. These issues will be resolved during the continuance period for Phase 2. 1. Runoff velocities along the roadside ditches may be erosive due to the steepness of thc slopes. What permanent methods of erosion protection are planned? • Riprap on erosion control liner will be installed in areas of excessively steep ditch slopes that are subject to significant erosion. This will be designated at the time of Final Plat for Phase 2. 2. Considering that native vegetation is sparse, that outside irrigation is limited, that these slopes are south facing, what methods will be implemented to guarantee that these slopes will be revegetated? Perhaps other permanent erosion control methods could be investigated besides revegetation. • These slopes will be seeded during the preferred time of year and erosion control fabric will be used until adequate vegetation is established. A permanent erosion control fabric with seed will be used. 3. The flow arrows show concentrated flow directed onto Lots 9, 10, 19, 20, and 24 in the most feasible location for building envelopes. Drainage easements will be necessary and they would likely bisect the envelopes. Have alternative routings been considered? • These flows follow historic drainage patterns for the site. The drainages will be considered at the time of determining the building envelopes. 4. A low point is created on thc uphill side of the road through Lot 21 that does not appear to have drainage considered. What is planned to drain this low point? • A more defined channel will be added to provide adequate drainage at time of Final Plat. 5. All the runoff from this site appears to flow down hill to the east and CR 319. There is insufficient detail and topography to show what is there and where the runoff will flow. How does the runoff tie to the drainage of CR 319? • A field investigation revealed that both culverts under County Road 319 are 60" culverts. The first existing culvert under CR 319 is located to the north of the intersection of Grass Mesa Road and CR 319, An 18" culvert is also in place across Grass Mesa Road at the intersection to provide drainage to the larger culvert under CR 319, The second existing 60" culvert is located under CR 319 south of the proposed intersection of CR319 and the proposed access in Phase 2. A 16" culvert is installed under the proposed access road at this intersection to provide drainage to the south 60" culvert. These culverts will be indicated on the Final Plat submittal. Ma,nm Creek Commons Page 6 of 13 FROM :MountainCrossEng,Inc FAX NO. :9709455558 Jul. 13 2004 03:22PM P7 GR -3 1. What vehicle will be used for maintenance of the pump station and water tank? Will the turning radius of that vehicle be small enough to maneuver around the tank and pump station as shown? ■ A 10 ft inside radius and a 22 ft outside radius should be sufficient to provide adequate access to the limited access site. GR -4 1. Runoff velocities after the cut ditch when on the native slope may be erosive due to the steepness of the slopes. The note calls to protect the fill slope with riprap but it may be necessary to protect the native slope also. What permanent methods of erosion protection arc planned? ■ At the time of Final Plat, the note will be changed to state "Daylight to existing grade. Divert flow away from fill slope to existing grade. Use rip rap on erosion control liner to protect fill slope and transition zone to existing grade". 2. What vehicle will be used for maintenance of the pump station and water tank? Will the turning radius of that vehicle be small enough to maneuver around the tank and pump station as shown? ■ A 10 ft inside radius and a 22 ft outside radius should be sufficient to provide adequate access to the limited access site. RD -01 1. The culvert at 2+63 is described as both a 36" culvert and a 60" culvert. ■ A field investigation indicated this is a 48" culvert. This will be updated at time of Final Plat. 2. There may not be adequate cover on the upstream end of the 24" culvert at 5+53 if there is 12" of cover at centerline. The culvert will be lowered and grading will be altered to provide drainage. 3. Based on the grading, it will be difficult to adequately cover the 18" culvert at 5+79. • The cover over this culvert will be improved with the change described above ander comment RD -01.2. RD -02 1. The intersection with Grass Mesa does not meet Garfield County intersection design standards. • Due to the severe condition of the site a variance is requested for this intersection. 2. What is the calculated slope at the connected vertical curves, 3+95? • The grade out of the vertical curve with a PVT at station 3+60.00 is —6.27%. 3. What will be the quantity of water crossing the road in the area of the warped road cross section, 4+26 to 5+05? Will this create erosive velocities? Calculations will be necessary otherwise a culvert should be installed. ■ Concentrated flows will be eliminated because of the change described above under Section GR -1.1.. The flows will be consistent with historic flows. 4, How will water be conveyed across driveways? ■ Culverts will be added under driveways. Grading will be completed to accommodate drainage. Mamm Crook Commons Page 7 of 13 FROM :MountainCrossEnq,Inc FAX NO. :9709455558 Jul. 13 2004 03:23PM P8 5. Will there be a cut ditch on the uphill side of the road? • No. The road section will be warped and a cut ditch is not necessary. RD -03 1. Thc 60" culvert is shown as proposed but the note calls to add headwalls to each end of the existing. • The culvert does exist. However, the culvert may need to be relocated and lengthened to provide adequate access to the lots. 2. How will water get across the access to lot 4? • A culvert will be added in front of Lot 4 (flowing toward Lot 3) allowing drainage to the proposed 24" culvert shown on RD -04. RD -05 • General response to RD -05 comments: This sheet is part of Phase 2 of the proposed Preliminary Plan. The issues below will be negotiated between the Review Engineer, the County, the Fire District, and the Owner to satisfactorily resolve these issues. These issues will be resolved during the continuance period for Phase 2. 2. How will thc arca of the intersection be graded, drained, and tied into existing? There is no existing topography and very little design information given for the intersection to CR 319. • This is part of Phase 2 and a resolution can be negotiated between necessary parties during the continuance period. Currently, topography of this area is unavailable. The proposed road will tie into the existing grade of County Road 319. The existing culvert under this access will be sized and reinstalled to provide adequate drainage from the north to the south where runoff can enter the existing 60" culvert under CR 319. 3. Thc International Fire Code has maximum grade requirements for roadways. Even though thc County may give a variance for the steep grade, the fire district may not provide .fire protection. The local fire district should review and respond in writing concerning the acceptability of the road grades. • We are awaiting comments and suggestions from the fire district. Any comments will be addressed in a fashion to satisfy all necessary parties during the continuance period. 4. The combination of steep and curved is particularly difficult to navigate during snowy conditions. Often a flat, straight section of roadway is designed to allow drivers to recover and/or drive up; however a steep curve makes it difficult to either get up or down. Driver loss of control and sliding should be expected. What different alternatives have been considered? What measures are proposed to make this road safer for travelers? • This site has many severe conditions that require additional investigation. Comments from the Fire District will be considered in determining the options for resolving this issue. As stated earlier, we are awaiting comments from the Fire District. 5. The cross slope of the minor road at 6+06 will need to match the road grade. It will make starting and stopping at the intersection extremely difficult for drivers. Superelcvations of 6% are maximum rules of thumb for sideways sliding during snowy and/or ice conditions; the cross slope of this road will be nearly 12%. Have Mamm Creek Commons Page 8 of 13 FROM :MountainCrossEng,Inc FAX NO. :9709455558 Jul. 13 2004 03:23PM P9 other points of intersection been considered? Has flattening the road grades of the major road been considered? • See previous comment. The condition at this intersection will change with any changes to the road. 6. Berms and/or guardrail should be installed for the curve to protect Lot 15 from out of control vehicles. • Guardrail will be installed along this stretch. 7. Guardrail should be installed along the downhill side of the roadway. • Guardrail will be installed along the downhill side of the roadway between Station 8+00 and 15+00 on Sheet RD -06. RD -06 • General response to RD -06 comments: This sheet is part of Phase 2 of the proposed Preliminary Plan. The issues below will be negotiated between the Review Engineer, the County, the Fire District, and the Owner to satisfactorily resolve these issues. These issues will be resolved during the continuance period for Phase 2. 1. The International Fire Code has maximum grade requirements for roadways. Even though the County may give a variance for the steep grade, the fire district may not provide fire protection. The local fire district should review and respond in writing concerning the acceptability of the road grades. ▪ We are awaiting comments and suggestions from the fire district. Any comments will be addressed in a fashion to satisfy the fire district, the county and the owner. 2. The combination of steep and curved is particularly difficult to navigate during snowy conditions. Often a flat, straight section of roadway is designed to allow drivers to recover and/or drive up; however a steep curve makes it difficult to either get up or down. Driver loss of control and sliding should be expected. What different alternatives have been considered? What measures are proposed to make this road safer for travelers? • This site has many severe conditions that require additional Investigation. Comments from the Fire District will be considered in determining the options for resolving this issue. As stated earlier, we are awaiting comments from the Fire District. 3. Guardrail should be installed along the downhill side of the roadway. • Guardrail will be installed along the downhill side of the roadway between Station 8+00 and 15+00 on Sheet RD -06. 4. The length of the cul-de-sac exceeds the acceptable length. A variance will be necessary. Also, the local fire district should review and respond in writing concerning the acceptability of the cul-de-sac length. It is typical that longer lengths have a second point of emergency ingress and egress. Where is the second point of access proposed? • Due to the severe terrain and location of the cul-de-sac, a second point of access is not located. 5. As part of the variance process, a graphic illustration needs to be provided showing the difference between complying with grades and with excessive grades. This is to be performed to show that cuts and/or fills that exceed 12' in height can be avoided. Mamm Creck Commons Page 9 of 13 FROM :MountainCrossEng,Inc FAX NO. :9709455558 Jul. 13 2004 03:24PM P10 In this case, even with the excessive grades, fill heights at centerline exceed 17'; fill heights from toe of fill to centerline exceed 40' in places. With this large amount of fill, what specific recommendations has the geotechnical engineer made? • The fill for this road was kept to a minimum for reasons within the geotechnical report. The geotechnical engineer will need to be involved and agree to the plans and construction of the excessive fills. RD -07 1. A low point is created at 2+75(+/-) that does not appear to have drainage considered. What is planned to drain this low point? ■ A more defined channel will be developed at time of Final Plat. 2. An access easement will need to be provided that bisects Lots 21 and 22. This is generally discouraged. Have other alternatives been considered to shift the access to common arca and/or a lot line? ■ An easement is shown on Sheet RD -07. This should be shown on the preliminary plat. Alternate routes moving the road to the property line would create significant fill amounts resulting in a less stable and more d-angerous- access. RD -09 1. The cross slope of the road at 6+06 will need to match the major road grade. It will make starting and stopping at the intersection extremely difficult for drivers. Superelevations of 6% are maximum rules of thumb for sideways sliding during snowy and/or ice conditions; the cross slope of this road will be nearly 12%. Have other points of intersection been considered? Has flattening the road grades of the major road been considered? ■ Sec Comment 3 under Section RD -05. The condition at this intersection will change with any changes to the road. 2. The culvert is referred to in plan as 36" and in profile as 24". Either one will require a relatively steep and deep hole to drain the roadside ditch into the invert of the culvert. This will further complicate the difficulties that cars will potentially have after sliding off the road and into the deep roadside ditch. Has the ditch and culvert been considered further from the intersection? ■ To clarify, the proposed culvert is a 36" culvert. The culvert will be moved to approximately Station 1+60 and located approximately at the low point. Roadside drainage will be graded to drain to the new location. A "hole" may still have to be created to provide adequate drainage. This "hole" will be protected from the road with guardrail. 3. Also, when considering the above comment, consider that there is a low point in the road at approx. 1+50 that has not been considered for drainage. ✓ See previous response. 4. The access into lot 15 is steep. Have other alternatives been considered? Perhaps the access into lot 14 could be steepened and shifted to the west and the grades flattened for the access into 15. ■ The existing grade on the cast side of Lot 15 is approximately the same grade as the proposed access. While other alternatives may slightly improve the grade to Lot 15, they would cause additional problems for necess to Lot 14 and the intersection with the road servicing these access roads. Mamm Creek Commons Page 10 of 13 FROM :MountainCrossEng,Inc FAX NO. :9709455558 Jul. 13 2004 03:24PM P11 RD -10 1. The intersection proposes to transition immediately to the vertical tangent. This does not meet the intersection requirements of the County. That aside, what vehicle will be used for maintenance of the pump station and water tank? Has the wheel base and ground clearance of the maintenance vehicle been considered for this proposed access? • This is a limited access road. A variance is requested for this road. A 10 ft inside radius and a 22 ft outside radius should be sufficient to provide adequate access to the limited access site. 2. The culvert inlet appears to be shifted uphill of where the low point would be. Will the culvert be able to drain the low point? • The culvert will be shifted up station and local grading will be completed to insure drainage to the culvert. MU -1 (Items 1-3 shown above under conditions section) 4. What is the proposed routing for phone and power systems? t This will be addressed at Final Plat. 5. The 6" watcr line into Phase II is proposed off the property and within the CR 319 right-of-way. What arrangements and or agreements have been made to show this as planned? • Agreements- will be in place between the county and the owner prior to the construction of the waterline. 6. The ISDS for Lot 6 will have considerable setback requirements with the well and water lines. Has this lot been evaluated to see if buildings, setbacks, and ISDS are all feasible? • All .!SDS leach fields will be on the individual lots or in the Common Open Space. Each ISDS design will be completed at the time of the building permit, at which time setbacks will be more specifically investigated. 7. What is the proposed cover over the water lines? What is proposed for the water line vs. culvert crossings? • All waterlines will be installed with 5 feet of cover. Insulation will be used at the culvert crossings. 8. What is proposed for the high point in the water line in front of Lot 10? ■ An Air/Vac valve will be added at this location. 9. No shut-off or isolation valves are shown for the new water line construction. Is this intentional? • Shut off and isolation valves will be added based on the hydrant locations and will be situated to best suit the system. 10. The 6" water lines to Tank #2 and to Lots 1, 2, 3, and 4 are labeled as existing. What is the status of these lines? When were they constructed? What specifications were used? Were they pressure tested? Were they chlorinated? • This will be clarified on the Final Plat. Mom= Crook Commons Page 11 of 13 FROM :MountainCrossEng,Inc FAX NO. :9709455558 Jul. 13 2004 03:25PM P12 MU -2 (Reins 1-4 shown above under conditions Rection) • General response to MU -2 comments: This sheet is part of Phase 2 of the proposed Preliminary Plan. The issues below will be negotiated between the Review Engineer, the County, the Fire District, and the Owner to satisfactorily resolve these issues. These issues will be resolved during the continuance period for Phase 2. 5. What is the proposed routing for phone and power systems? • This will be addressed at Final Plat. 6, What is the proposed cover over the water lines? What is proposed for the water line vs. culvert crossings? • All waterlines will be installed with 5 feet of cover. Insulation will be used at the culvert crossings. 7. What types of joints are proposed for the water lines constructed in the fill slopes? Thrust blocks and push -on joints may pull apart as the fill settles over time, • Restrained joints will be used in any areas of significant fill. Notes will be added to the drawings indicating specifically which areas will require restrained joints. 8. The fire hydrant should be shifted to the uphill side of the road so that thrust is into the hill instead of out of the hill. The 6" line should terminate into the hydrant. Water services for Lots 22 and 23 should tap into the 6" line. • The fire hydrant will be moved to the other side of the road. MU -3 (Item 1 shown above under conditions section) 2. Where will the floor drain actually daylight? The daylight end does not show up on GR -1, GR -3, MU -1, or RD -01. • This will be addressed at Final Plat 3. Where will the chlorine solution be injected into the water system? • This will be addressed at Final Plat. 4. Even though shop drawings are to be submitted for approval, building specifications and performance criteria will be necessary. • This will be addressed at Final Plat. 5. Where will the pressure switch be located? • This will be addressed at Final Plat. 6. Does the foundation wall detail incorporate the site recommendations of the soils report specific to the pump house? • The foundation detail will be revised. The geotechnichal engineer will provide site specific design requirements at the time of building permit. MU -4 1. Where will the overflow drain actually daylight? The daylight end does not show up on GR -1, GR -3, MU -1, or RD -01. • This will be addressed at Final Plat. 2, On this relatively small tank, will a center support be necessary? If not where will the float and overflow switches be located? • The tank will be designed by others and provided at Final Plat. Marnm Creek Commons Page 12 of' 13 FROM :MountainCrossEn9,Inc FAX NO. :9709455558 Jul. 13 2004 03:25PM P13 3. Is there concern with vandalism? Does the ladder need to be shortened to prevent access? • Suggestion noted and will be addressed and incorporated in the tank design at Final Plat. 4. The funnel weir/orifice is 24". What flow rate determined this size? The drawing shows the supports for the overflow assembly to the tank wall but the note calls for it to thc center support. • The tank will be designed by others and provided at Final Plat. 5. Since there is elevation available elsewhere within the project, what is the reason for locating this tank at a lower elevation? The VFD pumps, pressure tanks, backup generation, as well as the duplication in the second pump house could all be eliminated with a suitable higher elevation. • The owner preferred the proposed configuration for the water system. DET -2 1. Two details exist for thrust blocks that do not correlate. • One of the details will be removed.

District 38 Dear Jim, This correspondence is intended to follow-up and confirm our telephone conversation relevant to the above referenced matter which was the subject the the "material injury" letter issued by your office to Jim Hardcastle, Garfield County Planning Department, of June 23, 2004. I also discussed this matter with Dick Wolfe this morning who suggested that given the pendancy of the Garfield County Planning Commission's review of this application (tonight at 7:30 p.m.) that I follow this format. As previously represented the total estimated water supply for the Mamm Creek Commons is slated for augmentation under the West Divide Water Conservancy District Water Allotment Contract (No. 040219W(a)) by and between the District and the 319 Water Company. Any comments to other augmentation sources contained within the application materials reviewed by your office are either in error or are mistated references to District contract. All domestic depletions within the Mamm Creek Commons are to be augmented under the District contract. It is my understanding that all domestic depletions as such will in fact be augmented under the District's substitute water supply plan until such time as the District formally includes its contract with 319 Water Company within it Augmentation Plan pursuant to court decree. As such, these depletions should not cause, pursuant to CRS 30-28-136(1)(H)(I), material injury to other decreed water rights If you could confirm the above to Jim Hardcastle at jhardcastle@garfield-county.com, it would greatly facilitate the review of the application by the Garfield County Planning Commission this evening Should you have any further questions or concerns regarding the above, please feel free to contact me at your convenience. My telephone number is (970)945-6546. Very Truly Yours, Timothy A. Thulson i
