Our project encompasses a 50 acre site located on Northwood Drive approximately 1,200 feet north of Mile 3 on Rabbit Creek Road. We feel that; the cluster development and our proposal in particular is appropriate for the site. The existing soils on this site preclude development on this land under existing R-6 zoning. This cluster ~evelopment incorporates a comprehensive distribution system for all utility services except sewage. An overall land use plan also has delineated ()pen space in addition to residential lots. Our description narrative follows. We feel this project is appropriate for 'the site and in keeping with the community's dew, loping character. We ask you for your support. Sincerely, William C. Hagmaier Project Engineer WCH:dd EAGLE RIVER ANCHORAGE[ HOMEiR (~694.9846 (~ ~9.6~1 (~235.8179 BAVARIAN HEIGHTS SUBDIVISION CLUSTER DEVELOPMENT A. SITE DESCRIPTION: This site is located in the Hillside area north of Rabbit Creek Road and west of Prator Street. The area en- closed by this development contains 50 acreso The topo- graphy in the eastern half of the develo~nent has an average slope of approximately 13%. Vegetation in this area is com- posed of black spruce, white spruce and cottonwood trees with isolated stands of birch and alders. The south central half of the property has a slight slope of 2% to the west, with vegetation restricted to sedges and marsh grass with in- termittent stands of black spruce and birch trees. This portion of the site is noticeably affected by a surficially saturated peat condition. The northern half of the site varies topographically from a negative 13% grade on the east side of the property westerly to a saturated peat bog locat- ed in the north central portion of the site. The northwest corner of the site is typified by a 20' knoll with side slopes approximating 14%. The property is zoned R-6 as is all the surrounding pro- perty adjacent to this subdivision. Access to and from the property is excellent and will be via Northfield [)rive to Rabbit Creek Road. The property is ewned and will be developed by Bridger Enterprises of Eagle River. B. PLANNING OBJECTIVES: The petition area is currently zoned R-6, suburban resi- dential district (large lot). The R-6 district is designed to encourage residential development whi].e at the same time preserving and enhancing those physical and environmental features which add to the desirability of suburban living. As the site is presently zoned, the minimum lot size is 1 1/4 acres. Due to soil conditions (predominantly clay and hardpan silt) the present zoning allows little flexibility in lot layout and in siting the dwelling units. The primary planning objective of the proposed cluster development is to provide single family residential dwelling units with minimum environmental disturbance. The existing soils on this property preclude standard R-6 residential development because of their impervious nature in terms of septic waste disposal. It is this feature that has dictated our planning objectives as follows: a) retain a significant portion of the site in its natural state. b) provide quality housing to the public at the most affordable cost. c) minimize aesthetic disturbance to adjacent areas by providing screening easements and greenbelt areas. These objectives cannot be met under the current R-6 zoning. Approximately half of the 50 acres is totally unsuitable for a typical R-6 lot with both on site waste disposal system and water well. Because the existing soils totally preclude development under this zoning, a community water system is required to serve any dew~lopment on this tract of land. The economics of constructing a community water distribution network and corresponding pumphouses dictates the fact that the density must be maintained at the R-6 level with the homes clustered within the area of suitable soils. The plan that has been submitted for this subdivision has taken into account all technical, economic and aesthetic censiderations, as listed abow~ in our planning objectives. The optimum solution to the constraints upon this property is a clustered community of open space and residential homes with a community water and on-site septic system. We are therefore requesting a density of 0.8 dwelling units per acre in order to meet the planning objectives that we have outlined above° C. PROJECT DESCRIPTION: The project will consist of 40 single family dwellings with an average lot size of 23,000 sq. ft. Each home will have its own private yard and quick access to the ()pen space area. In addition, an internal greenbelt along all roads within the subdivision will be maintained by use of setbacks. This will decrease the visual clustering of the project and provide a more private identity to each of the individual residences. The final aspect of this PUD is the retention of undisturbed open space at the north central and southerly areas within the property~ The construction of individual residences will be gover- ned by the architectual control committee and by the coven- ants, conditions, and restrictions for Bavarian Heights. The covenants, conditions and restrictions for this subdivis- ion are attached with this report. D. OPEN SPACE: The tract of land that currently exists off Rabbit Creek Road lies in a a relatively undisturbed and natural state. It is the petitioner's intent to leave the land in its natural state as much as possible. With the exception of roads and residential home sites, the site will be left in its natural state. Incorporated within the covenants will be provisions to restrict the amount of land that can be cleared for home construction. There will be two types of open space provided in Baw~rian Heights Subdivision. The first type will be held in private ownership by the owners of Lots 1-40. The private open space will be approximately 19,500 sq. ft. per lot which excludes the main structure, driveways and parking aprons. The second type of open space is undisturbed native vegetation which is held in common by the Homeowners Association. This open space is intended to preserve the natural surroundings while, at the same time~ serving as a buffer to the adjacent areas~ These areas are shown as Tract A, B, and C. Total acreage of the undisturbed open space is 21.65 acres. E. ]~NDSCAPING: The natural vegetation on the site consists of feur major plant associations: mixed white spruce/deciduous forest, black spruce forest, scattered birch and alder, and a shrubby wet bog area. Following the drainage pattern, the white spruce/ deciduous forest is found along the eastern ridge of 'the property° Acting as a natural and visual buffer between the Bavarian Heights Subdivision and adjacent land owners, a 25-ft. building setback has been established to retain its character. A very nice stand of mature black spruce is found along the southwest property line. The shrubby wet bog is found at the north central property line and has been left in its natural state. By allowing for existing drainage patterns and establishing a proper development buffer around it, the integrity of the bog will be maintained. Like most of Alaska's natural environment, the existing vegetation is sensitive to development. To minimize impact on the landscape, all manmade cuts will be as minimal as possible and will be seeded and restored to a natural state. In additien to preserving the existing vegetation found on the site, an accent planting area has been provided at the entrance to the subdivision. This landscaped area, with a 6-ft. wood frame, earth mounding and identification sign, sets the mood for the subdivision along with providing separation from existing houses. Plants, selected for their color and ornamental characteristics, will include crabapple, mountain ash, mayday, birch, juniper, roses, lilac, honeysuckle, and cottoneaster. It is the intent of Bavarian Heights Subdivision to cenvey a natural park-like atmosphere through proper land use. This will be accomplished by minimizing impact on the existing natural environment, incorporation of develepment setbacks and maintenance of buffer vegetation. PUBLIC UTILITIES: All utilities for this cluster development will be installed by the developer (with the exception of on-site septic systems). The water system serving this subdivision will be a community system consisting of three to four wells, a pump house and a distribution system which will meet municipal and state D.E.C. criteria. The water rights for this property have been permitted by the Department of Natural Resources in the amount of 31,500 gallons per day. The Homeowners Association will be responsible to sign a contract with a licensed laboratory for the monthly samplings of the water system. The cow~nants, conditions, and restrictions for Bavarian Heights Subdivision provide for a monthly assessment to be levied on each homeowner for maintenance of the community facilities as may be necessary. This monthly assessment will be utilized to pay for all road maintenance that may be necessary, monthly sampling of the water system, maintenance on the water distribution systems, and main- tenance on all ()pen areas that are held in common by the homeowners of Bavarian Heights Subdivision. These monthly assessments will be put into an escrow account and will require two signatures for dispursement of any funds. This method should insure.that sufficient monies are available at such time as any major expenses would occur. Electrical service to this subdivision will be provided by C.EoA., gas service by Alaska Gas, and telephone service by A.T.U. G. TRAFFIC ANALYSIS AND VEHICLE CIRCULATION: Access to this subdivision will be from Rabbit Creek Road[ via Northfield Drive. Internal circulation will be attained by traffic flow on Northfield Drive which will als() serve as the main residential thoroughfares. It is the petitioners intent to upgrade Northfield Drive to a strip paved road from Rabbit Creek Road to this subdivision. In addition, all internal roads will be strip paved with drainage control. Based on current estimates of driving habits, the proposed 40 lots would generate 320 vehicle trips per day on Northfield. The capacity of Northfield Drive when improved by the petitioner will more than handle the increased traffic flow. No on-street parking will be allowed on any streets. The front yard setbacks for the R-6 zone have been maintained and thus all parking will be restricted to driveways only. H. S~TE DRAINAGE: Site drainage will be accomplished by use of roadside ditching and subdrainage throughout the property. Each road prism will incorporate a subdrain to receive any and all groundwater. In addition all roadside drainage that infiltrates into the adjacent road prism will also be disposed of through the subdrainage system. The outfall for the drainage system will be via drainage easement to the headwaters of Gold Creek. All downstream drainage culverts have been examined and have been rated as more than sufficient to pass this minimal addition to the present flow. It has been estimated by drainage modeling that the quantity of water resulting from this subdivision is cfs. The current flow of water in this drainage ditch/creek is approximately 2-3 cfs., mest of which presently originates from this property as a groundwater source. I. DEVELOPMENT SCHEDULE: It is the petitioner's intent to complete the develop- ment of the roads, water system, and other utilities during the 1983 construction season. Additionally any landscaping will be completed during 1983 if possible. If the landscaping cannot be completed before August 15, 1983, this work will be delayed until the 1984 season. Paving will not be performed until the 1984 censtruction season in order to allow for any secondary consolidation of the roadway during the first year. Development and construction on the individual 'lots will be by the private lot owner and will occur over the next three (3) years (estimated). J. ENVIRONMENtaL CONCERNS: During the development of the project careful consideration will be given to air quality and noise impact in order to minimize the interim disturbance during construction. All equipment will be suitably muffled and the access road into the project, Nerthfield Drive, will be treated with CSS-1 to minimize any dust. K. OWNERSHIP: Lets 1 through 40 will be offered for sale to the public~ Ownership of the individual lots will transfer to the private owner. Tract A, B and C will be held in cemmon ownership by the new Bavarian Heights Home Owners Association for use by its members and their guests. L. CLUSTER DEVELOPMENT STRUCTURE: Attached with this application is a preliminary copy of the Protective Covenants and the Home Owners Association Agreement for the proposed[ subdivision. As described in the covenants~ a home owners association will be formed. The purpose of the association will be to maintain the co,non areas and to carry out the intent of the covenants. The association may adopt bylaws and elect officers to conduct its affairs, make improvements to the subdivision, bring legal action to enforce the covenants and other type of lawful actions. The agreement also provides for common us- age of Tract A, B,and C, by all residents of Bavarian Heights Subdivision. M. PARKING There will be no roadside parking allowed. Ail lots will have adequate driveways and parking areas to preclude any roadside parking. (All road within the subdivision will be signed with "No Parking" signs.) N. TRASH DISPOSAL: Roadside trash disposal service will be provided to the project area by Anchorage Refuse on a weekly basis as is provided to similar projects throughout Anchorage. O. MAIL SERVICE: Mail delivery boxes will be placed at roadside locations by the builders of each respective lot with 'the Post Office providing delivery service.

Every purchaser, his heirs, assigns and successors in the ownership of lots in this subdivision agrees as a condition of purchase that he is automatically a member of the Homeowner's Association. He will abide by the policies now set and as later may be amended by majority decision. He will support such policies and will pay such assessments as may from time to time be levied. The Homeowner's Association will be operated by the sudivider until such time as more than 50 percent of the lots subject to Association 3urisdic~:ion have been conveyed to the ultimate consumers (contractors and other purchasing any of said lots for resale shall not be deemed to be "ultimate consumers"), or October 31, 1985, whichever first occurs, at which time the Association will De activated and there will be an election of officers and[ Executive Committee and dues will De established and levied as determined by the Executive Committee. D-2. VOTING RIGHT-~;. The Association shall bare one class of voting rights.

Eligible votes may be cast on all matters that may come before a meeting of the Association. D-3. CREATION OF THE.~0IEN AND PERSONAL OBLIGATION OF ASSESSMENTS.. The lot owners for each lot owned within the subdivision hereby covenant, and each owner of any lot by acceptance of a deed therefor, whether or not it shall be so expressed in such deed, is deemed to covenant and agree to pay the Association: (1) Annual assessments or charges, and (2) Special assessments for capital improvements, such assessments to be established and collected as hereinafter provided. D-4. CONVEYANCE AND SUBORDINATION. The Association shall have the power to assess fees to the lot owners to achieve the objectives of the Homeowner's Association. The lien of the assessments provided for herein shall be subordinate to the lien of any mortgage. Sale or transfer of any lot shall not affect the assessment lien. However, the sale or transfer of any lot pursuant to mortgage foreclosure, or any proceeding in liey thereof, shall extinguish the lien of such assessments as to payments which become due prior to such sale or transfer. No sale or transfer shall relieve such lot from liability for any assessments thereafter becoming due or from the lien thereof. D-5. ANNUAL ASSESSMENTS. The Association will be operated by the subdivider until such time as more than 50% of the lots subject to Association jurisdiction have been conveyed to ~;he ultimate consumers (contractors and others purchasing any of said lots for resale shall not be deemed to be "ultimate consumers"), or October 31, 1985, whichever first occurs. Tile fiscal year for assessments shall be from Now.~mber 1st through October 31st. Upon purchase of a lot or lots by a purchaser, the purchaser shall, at the time of closing, pay the pro rata annual asse.~;sment remaining for the fiscal year's assessment plus one full annual assessment fee of $ which will cause purchaser's annual assessment to be paid through October 31st of the year subsequent ~:o purchase. The subdivider will not pay any assessments for unsold lots but will make up any deficits in the maintenance expense until such time as all lots in the subdivision have been sold. At such time as the Homeowner's Association is activated, the Soard of Directors may fix the annual assessments. D-6. EMERGENCY PROVISION. The Board of Directors may fix an Emergency Assessment, not in excess of per lot, by a two--thirds vote of the entire membership of the Board. The Board of Directors shall have sole discretion as to what constitutes an emergency so long as such dtscreation is exercised justly and reasonably. Such assessment shall only be fixed at a duly constituted meeting of the Board, when= a. Conditions do not allow timE: for a special or regular meeting of the Association mambership to be called, and b. An emergency exists which requires immediate &ction (endangers life, property, or use of the properties), and c. The Association's funds are not: adequate to pay to cost of action to be taken. D-7. SPECIAL ASSESSMENTS FOR CAPITAL IMPROVEMENTS. In addition to the Annual and Emergency Assessments authorized above, the Association may levy, in any assessment year, a Special Assessment applicable to that year only, for the purpose of defraying, in whole or in part, the cost of any construction, reconstruction, repair, or replacement of a Capital Improvement or upon public roads, including rights-of-way, serving thE! subdivision~ including fixtures and personal property related thereto, PROVIDED THAT any such assessment shall have the assent to two-thirds of the lot votes represented at a meeting duly called flor this purpose. D-B. NOTICE REQUIREMBNTS. Written notice of any meeting called for the purpose of taking action authorized under Sections D-5 through D-7 shall be sent to all members not less than fifteen (15) days nor more than thirty (30( days in advance of the mee~:ing. At the first such meeting called, the presence of members or of proxies entitled to cast sixty percent (60~) of all votes shall constitute a quorum. If the required quorum is not present, another meeting may be called subject to the same notice requirements and the required .quorum at the subsequent meeting shall be one-half of the required quorum at the preceeding meeting. No such subsequent meeting shall be held for more than sixty (60) days following the preceding meeting. D-9. UNIFORM RATE OF ASSESSMENT. Both Annual and Special Assessments must be fixed at a uniform rate for ali. lots and may be collected on a monthly, semi-annual, or annual basis by the subdivider or the Association. D-10. DATE OF COMMENCEMENT OF ANNUAL ASSESSMENTS, DUE DATES. The first Annual Assessment shall be paid as set forth in paragraph D-5 above. The Board of Directors shall fix the amount of the Annual Assessment against each lot at least thirty (30) days in advance of each Annual Assessment period. Written notice of the Annual Assessment shall be sent to every owner subject thereto. November 1 shall be the date Annual Assessment are due and payable. The Association shall upon demand, and for a reasonable charge, furnish a certificate signed by an office of the Association setting forth whether the assessments on a specified lot have been paid. D-11. EFFECT OF NONPAYMENT OF ASSESSMENTS: REMEDIES OF THE ASSOCIATION. Any assessment not paid within thirty (30) days after the due da~e shall Dear interest from the due date at the rate established by the Beard of Directors. The Association may bring an action, at law, against the owner personally obligated to pay the same, or foreclose the lien against ['~he property. No owner may waive or otherwise escape liability of the assessments provided herein by non-use of the Common Area or abandonment of his lot. D-12. TERMINATION OF ASSOCIATION. The Association shall be terminated upon the condition of a governmental agency causing to be created a Public Service District which will provide for the maintenance and repair of streets located within the subdivision.

S 7125 OLD SEWARD HIGHWAY ' ANCHORAGE ALASKA 99502 1983 Jerry Weaver Platting officer Municipality of Anchorage Pouch 6-.650 Anchorage, Alaska 99502 Dear Mr. Weaver: The following narrative is a drainage and hydrology analysis for Bavarian Hts. Subdivision. This letter is in- tended to quantify and qualify the existence of surface drainage, groundwater, wetlands, and to some extent the com- munity water supply for this subdivision. The 50 acres proposed for development is vegetated with a variety of native grasses and trees including alders, birch, black spruce and white spruce. The topography for the area shows a hill along the east boundary for this prop- erty and a predominant knoll located in the northwest corner of the property. The precipitation equiw~lent for both rain and snowfall in this area is approximately 15-.20 inches per year depending upon the year. The precipitation falling within the area of the subdivision and the adjacent sub- divisions flows in a westerly manner across Bavarian Heights Subdivision. This westerly flow of water across the surface of this 50-acre tract eventually finds its way to the headwaters of Gold Creek, located approximately 1200 feet west of Bavarian Heights Subdivision. The drainage basin for this area encompasses the 50 acres of the proposed Bavarian Heights Subdivision and an additional 20-30 acres east of Bavarian Heights Subdivision. The runoff from the property to the east is minimized due to the existence of a perenially flowing stream approximately 800 feet east/northeast of this subdivision which intercepts the surface water runoff from the upper hillside and channels it into Rabbit Creek. The amount of drainage originating from this fifty acres will not be changed by the addition of this subdivision. The only thing that will be changed will be the length of time for the drainage to reach Gold Creek. P.resently this flow reaches the creek by overland flow, whereas within the proposed subdivision it will reach the creek through a series of storm drains, grassed swales and drainage ditches. 5AGLE RIVER ANCHORAGE HOMER (907} 694-98~6 (907) 349.6561 (907) 235.8179 Page 2 S & S Engineers, Inc. Bavarian Hts. Drainage; February 21, 1983 91119 It is estimated that this subdivision will result in approximately 5.48 acres of impervious area. (2.73 acres of road area, 1.83 acres of homes, and 0.92 acres of driveways and other impervious areas). The drainage resulting from this additional impervious area will be channeled to the grassed swales adjacent to the roadways, in accordance with the road standards of Public Works Engineering. Engineering calculations presently put the total amount of surface runoff from this drainage basin to Gold C~eek at approximately 11.20 cubic feet per second. The addition of the 5.48 acres of impervious area would change the resultant creek hydrograph in that an additional 1.07 cubic feet per second of runoff would reach the creek sooner vi~ the' grassed swales and storm drainage system. The proposed subdivision partially lies within a stand- ing water area described on page 16 of the Hydrologic Study of the H~llside Area, prepared for the Boroughs, by %he U.S. Geological Survey in 1975. However, as stated on page 17 of this study, "field inspection is invaluable in evaluating any potential surficial drainage problem." The study goes on further in stating that "the peat material on the surface can act as a sponge in that it may be saturated one or two feet beneath the surface. The material below the peat, however, may not. be saturated.

Approximately half of this property is overlain by one to three feet of saturated peat with a very dense glacial till located just beneath the peat. The surface drainage provided by the roadway system and the underground storm drain system will d~finitely intercept the surface water presently saturating th~s peat. On page 28 of this same study, this area has been mapped out as being highly susceptible to surface and ground water pollution. The map of that area on page 28 coincides identically with the map on page 16. This designation of high susceptibility exists because it assumes that any conventional septic system installed in this area would discharge into a heavily saturated and permeable ground. Page 3 S & S Engineers, Inc. Bavarian Heights Sub. February 2]., 1983 I~1119 However, field investigation on this site has revealed that it is only the surficial area of peat that is saturated. An engineered drainage plan for this subdivision will result in the "drying out" of this surficially saturated muskeg. This proposed subdivision lies partially within Wet- lands Management Plan, Area ~:30; however, this area has been classified as acceptable for mixed development. In addition, a Nationwide Wetlands Permit was issued by the Corps of Engineers on August 19, 1981. The area of principal concern to the Corps was the north-central portion of this property which has been tracted out and will be left in its natural state. The community water supply system has three wells, a central pumping house and the distribution system of pipes. The three wells currently have a combined pumping capacity of 133 gallens per minute. The primary well is an artesian well rated at 88 gallons per minute, located in the southwest corner of the subdivision. The second well rated at 37.5 gallons per minute, is located at the entrance of the subdivision, adjacent to Northfield Drive. The third well, rated at 7.5 gallons per minute, is located midway between the first and secend wells and approximately 150 feet north of the south property line. All three wells are located approximately 500-900 feet away from any private well. All three wells vary in depth from 140' to as deep as 210 feet. The effect of the proposed community well system upon the aquaifers currently serving residents along both the Prator and Mercedes Hill areas has been evaluated by the Dept. of Natural Resources under the water rights permitting processes and this department has granted water rights of 31,500 gallons per day for this subdivision. Page 4 S & S Engineers, Inc. Bavarian Heights Sub. February 21, 1983 Job ~1119 The community water system as proposed is of sufficient capacity to service the proposed subdivision and has sufficient horizontal and vertical separation from any on-site wastewater disposal system. In addition, all the requirements of all responsible agencies governing the water systems have been complied with. The information contained in the above narrative is the result of numerous site investigations, engineering anal- ysis, and research.

This drainage plan has been engineered so as to lower the water table in the areas susceptible to ground water contamination from on-site septic tanks. The drainage system proposed for this development is shown as a blueline drawing attached to the subdivision plat. The drainage system will be composed of both fin ~rains and (~P storm drainage. Both types of proposed drainage are shown on the attached drainage plan. The fin drains will be utilized to intercept the high ground water and lower the groundwater elevation by re-directing 'the drainage through the subdivision The drainage system will then discharge this water to the headwaters of Gold Creek, which is where the present groundwater ultimately ends up. The drainage system as proposed has not increased the amount of drainage to Gold Creek. The purpose of the drainage system is only to permanantly de-water and lower the existing ground water to an elevation acceptable to Dept. of Environmental Protection so that on-site septic systems will function properly, and not contaminate the existing ground water. The fin drain system consists of sections of a flexible vertical fin made of deeply dimpled high strength styrene sheet enveloped in a non-woven polypropelene filter fabric. Perforated plastic pipe is inserted[ into each unit and connected, forming a continuous drainage curtain. Each section of pipe has a flap of fabric that overlaps the adjacent section, preventing any movement of soil into the system~ The vertical fin provides channels on both sides, permitting water to flow vertically to the perforated pipe at 'the base of the fin.

Bavarian Heights Drainage System; February 22, 1983 Job 1119 Upon entering the perforated plastic pipe, the water is then conveyed to the drainage system as shown on the attached drawings. As can be seen from the attached drawings, the fin drains will be utilized to lower the groundwater table by installing these systems upstream of the affected areas. Thus, the fin drain system and connecting storm drainage will act as both a groundwater barrier and drainage conw~yance system. The drainage plan as proposed, was engineered so as to mitigate any impact on the area of standing water in the north-central portion of this subdivision. At the present time, as can be seen from the test hole logs and soil profiles accompanying this report, the water from this bog flows toward the headwaters of Gold Creek through a series of sand and sandy gravel deposits, running in a south-westerly direction across this property. The table below shows the engineering coefficients of permeability for the soils through which the water presently runs in comparison with the permeability coefficient for the fin drain. As can be seen from the table, the permeability coefficients are relatively equal. The permeability of the filter fabric is in fact less than some of the existing soils. Thus, the installation of this fin drain and storm drainage plan will not have any detrimental eff~c~..on th~. bog in terms of lowerlng the water tab"~.

Bavarian Heights Drainage System; February 22, 1983 Job 1119 The drainage system as proposed will lower the ground water table in the affected area without disturbing any of the adjacent areas. The drainage system as proposed will lower the groundwater table a minimum of 4' below soils acceptable for on-site septic systems, in conformance with the requirements of the Dept. of Health and Environmental Protection. There is adequate slope across the property and to Gold Creek to convey this water without any engineering constraints. The system as proposed provides for an economical and environmentally safe development, as well as insuring that there will be no detrimental effect upon any of the adjacent lands. I hope the foregoing discussion will help alay your fears as to the intentions for drainage and on-site septic system installations within this subdivision. If you have any questions regarding the proposed engineering design, the specifications, engineering analysis or construction details, please feel free to call me at 694-9846. Sincerely, W~lliam C. ~agmaier Engineer WCH:dd February & ENGIINEERS, INC. 7125 OLD SEWARD HIGHWAY · ANCHORAGE, ALASKA 99502 18, 1983 Mr. Rexford Turner P.O. Box 589 Eagle River, Alaska 99577 RE: Preliminary soils exploration and percolation tests for Bavarian Heights Subdivision. Dear Mr. Turner: The information contained in this report is the result of our preliminary soils investigation on the Bavarian Heights Subdivision, ~)per Rabbit Creek Road area. Our investigation included the review of previous soils investigations, research of soils d~ta on surrounding property, and field examination with backhoe test pits. Forty-four test pits were excavated and[ examined during October and November of 1981. The test pits were logged and representative samples were taken. These varied in depths from 12 to 21 feet and were spaced throughout the proposed subdivision area. Prior to this report, eight perc tests were performed by Moening, Gray, and Associates during July of 1979, eight test pits were excavated and examined during September of 1978 by Moening, Gray and Associates~ and[ four test pits were logged by John M. Lambe during December of 1977. The test pit locations for all projects are shown on Figure 1. In all cases, subsurface examination was accomplished with backhoe equipment. Surface drainage throughout the area is in a westerly direction except for the north central area of the property where a southerly trending swale occurs between the east ridge and a small, hill to the west. Drainage is excellent along the easterly ridge and small hill. Drainage in the afore-mentioned swale and southwesterly corner is moderate, due to the lack of suitable outfall. The water tends to percolate into the existing gravel, underlying the southwest corner of the subdivision. EAGLE RIVER ANCHORAGE HOMER (907) 694.9846 (907) 349.6561 (907) 235-8179 Page 2 S & S Engineers, Inc. Bavarian Heights Soils Report; Job February 18, 1983 1119 The surficial soils in this area were deposited during the final glaciation. The primary depositional agents included ice, streams, outwash, and ponds. These produced a somewhat complex series of materials varying widely in character. The northern half of the ridge extending along the east side of the property consists of several feet of silts and silty sandy gravel overlying a fairly well graded sandy gravel to gravelly sand. This material was quite dense and had a moderate to low moisture content with no water table conditions encountered. A slight water seep was encountered at 7' - 8' deep in three of the test holes dug. The percolation tests performed in this area were acceptable for on site waste disposal systems. In the southeast corner of the property, soils consist of a bluish gray sandy silt to clayey silt. The deposit is essentially impervious. It has a low moisture content and very firm consistency except were it is in contact with surface water. Test. pit information indicates the silts and clay are underlain by a w~ry dense sandy gravelly cobble. This material is also impervious. None of 'the perc tests performed in this area met the Municipal Standards for waste disposal systems. The small hill and side slopes in the northwest portion contain a thin veneer of silty sands overlying stratified sandy gravel to gravelly sand. These sands and gravels contain some very thin and apparently discontinous silt beds or lenses. The materials have a low moisture content and all test holes performed in this area will meet the existing Municipal criteria for on site waste disposal systems. The southwest corner of the property consists of gravelly cobble to sandy gravel which is overlain by a thin two foot veneer of silty sandy clays. In some locations closer to the southwest corner of the property the gravel comes entirely to the surface. These gravels are very pervious and at this time a water table exists in this area varying from three feet to nine feet. With proper drainage considerations, this area could meet the existing Municipal criteria for on site waste disposal systems. Page 3 S & S Engineers, Inc. Bavarian Heights Soils Report; February 18, 1983 Job 1119 We conclude that the area under consideration known as Bavarian Heights Subdivision is unsuitable for the most part under its present zoning for subdivision development. A cluster development or PUD is reeo~ended. As can be seen from the attached drawing, approximately 60% of the proposed subdivision property has ground that is unacceptable for on site waste disposal systems due to poor soils and/or groundwater conditions. A comprehensive drainage plan engineered for this 50-acre parcel would allow the use of on-site waste disposal systems on an additional 20-30% of this acreage. Drainage characteristics should be addressed during initial subdivision design. This is particularly important in the southwest corner of the subdivision where surface drainage improvements will be required. The water in the southwest corner of the subdivision apparently comes from a combination of surface flow off of the hill to the east and deep ground water flow coming out of the peat bog in the north central portion of this subdivision. Depending upon road configuration and subdrain placement, this area could w~ry easily be permanently dewatered. There are also some sporadic water seeps at varying depths located along the hill on the east side of the property and the mid central portion of the property. These water seeps are for the most part quite deep and should not interfere with any residential home foundations, nor any on site septic systems. Foundation subbase material will vary and also require individual attention prior to construction. For example, materia].s on site vary in frost susceptibility from NPS to F-4. Consistency of the granular material appears to be generally medium dense to dense. The finer materials or cohesiw~ soils appear to range from stiff to w~ry firm. Where exposed to excessive moisture~ commonly near the surface, the cohesive materials are soft. Because of the wide variety of soils within this large 50-acre tract, it is recommended that all foundation designs be subject to engineering analysis prior to foundation construction.
