MUNICIPALITY OF ANCHORAGE PLATTING BOARD CASE NO. S-6875 FINDINGS OF FACT AND DECISION IN CASE S-6875 WHEREAS, Bridger Enterprises sought plat: approval for Bavarian Heights Subdivision, a proposal to subdivide approximately 50 acres zoned R-6 into 40 lots and 3 tracts. Plat approval was so~lght under the cluster housing provisions of Title 21, Anchorage Municipal Code 21.45.190., and WHEREAS, the Platting Board held two public hearings on the application of Bridget Enterprises for approval of a plat for Bavarian Heights Subdivision on April 20 and April 27, 1983, and WHEREAS, the Board adopted the following findings and conclusions: Findings: 1. The site of tee proposed subdivision is a "water-logged" area, and much of the surface of the site is covered with two-three feet of peat saturated with water from surface drainage and subsurface flow. 2. Lowerisg the water table is necessary to allow development on the proposed lots with On-site sewage disposal systems as the existing shallow groundwater would be highly sl~sceptible to pollution from on-site sewage disposal systems. 3. Petitioner proposed to lower t~e water table by installing a curtain drain or, more precisely, a fin drain system. 4. It is not certain that the proposed fin drainage plan will succeed in lowerii%g the water table. The system's effectiveness should be demonstrated through at least two freeze-thaw cycles before ~n_Q~_ development commenced. 5. Wells in the area are already of poor quality. As such it is uncertain whether or not petitioner will be able to extract the necessary water to furnish water to the subdivision with a community water system. 6. Soil tests on the lots claimed to be useable without additional drainage were not deep enough to determine their suitability for on-site sewage disposal. Additional soil tests are needed prior to plat approval. Conclusions: 1. Due to the severe consequences of the drainage system's failure after development has co~u~enced, the plat applicant should bear the burden of demonstrating the drainage system's successful operation before plat approval, rather than the public bearisg the risk that the plan would prove inadequate after the plat ]]ad been approved and developmeet had commenced. 2. AMC 21.75.015 requires subdivisions "to assure adequate and properly placed utilities." Petitioner should demonstrate that there will be an adequate water supply system before any development is co~m~enced. -1- C, 15 Bavarial~ Heights Subdivision is in conflict with AMC 21.75.015. The plat conflicts with the public health, safety and general we[fare and with the provision of adequate and properly placed utilities. NOW , THEREFORE, be it resolved by the Platting Board that the plat is denie_~d, pursuant to AMC 21.80.180. THIS RESOLUTION ADOPTED by the Platting Board this 1].th day of July, 1984.

The entire PUD hinges on providing a c~nunity water and sewage system, both of which must be approved by the Alaska Department of Enviromnental Conservation. To this date (5/20), ADEC has not seen the proposed water system and has only briefly seen and discussed a conceptual sewage plan. With all the unknowns regarding soils permeability and depths, a backup sewage system, off- and on-site drainage (runoff) and its relationship to the surrounding area, the community sewage system itself, and the binding guarantees for the perpetuation of both 'the community water and sewage systems~ staff does not feel comfortable with even recom- mending "concept approval." We have met and talked with the petitioners several times to get the data requested which has been promised to either be forthcoming or they have requested conditioning approvals. Nothing has been submitted to this writing (5/20, noon). Although additional information may be received by public hearing time, staff does not feel it is fair to either the Planning Commission o~ the community to either do a hurried review or attach a long list of "conditions of approval" to such a sensitive project. To also be fair to the peti- tioner, we have recommended a postponement rather than denial.

MEMORANDUM DATE: May 18, 1982 TO: Platting and Zonin~ Division FROM: Physical Planning Division ~'; SUBJSCT: Zoning Case Reviews ~U 82-53: The; ~roposed development seems generally appropriate for this area of the Hillside, but it should be recognized that there may be substantial problems in its construction. Portions of the area included in the Planned Unit Development astride a "nonsuitable" area for on-site septic tank svstems, as shown in the Hillside Wastewater Plan. This delineation is the result of known wetlands, soils, and related environmental problems. Although individual on-site septic systems may not be practicable for this area, a com- munity water and sewerage system be feasible. If a com- munity sewerage system is provided, there must be guarantees as to its long-term effective operation and maintenance. Normally, this will be a requirement of the subdivision covenant and of the condition of the Planned Unit Development. The petitioner indicates that trails, open space, and screening easements will buffer this project for the existing, built-up lots. Generally, the reservation of por- tions of the tract at the periphery of the development seem to be in keeping with the concept o~ buffer and transition areas, but there may be difficulties with those tracts on the eastern boundary of the project. It is recommended that structures be located on the western portions of those par- cels to the extent practicable. The uses of cul-de-sacs and interior streets in the PUD is recognized and is considered desirable by this Division. ZP 82-52: The Division concurs that the development of this area at low residential densities would be generally difficult. The current Comprehensive Plan calls for higher density develop- ment of 11 to 20 dwelling units per acre to the west of the Bragaw/DeBarr intersection and for commercial development at the intersection itself. The revised Comprehensive Plan generally calls for residential development at the 11 to 20 DU range throughout the area, again excepting the intersec- tion at DeBarr and Bragaw. The revised Comprehensive Plan OO8 soil erosion and sediment control report should be required in order to minimize adverse impacts on Betzen Lake or Fish Creek. A Corps of Engineers permit may also be required. S-6304 - Portions of this subdivision appear to be in Wetland ~30, which is designated mixed development in the Wetlands Plan. The Plan requires a 65 foot structure and fill setback on either side of any creek. Such a creek easement should be required in '~'~his~ subdivision does not appear to be in wetland. ~--~P/DC/mm O07 DATE: TO: FROM: SUBJECT: MEMORANDUM Hay 5, 1982 Zoning & Platting M~sager - - .

Review PUD Plat S'-6-258, Bavariah 'Heights Snb~, Tracts with vacation A-D ~ topographic map of this subdivision and adjacent tax par- cels should be provided to resolve area drainage and road circulation. A PUD is inappropriate if it serves to restrict needed through circulation to adjacent tax parcels which may now lack either (or both) physical and dedicated access. Low lying areas with poor soils and deep peat should be identified; soils logs should be provided for evaluation by Public Works Engineering. Dedicated 60' ROW's should be extended south westerly from Bergweg Court and along the west property line to provide access to Tax Parcels 17-09-202 and 17-09-203. Also, addi- tional dedication is needed to extend Hauptweg Street to the north subdivision boundary. Al~o, a turnaround should be provided on 142nd Avenue. Cul-de-sac having more than 600' in length is not acceptable. A public use easement and drainage easement is needed along the south subdivision boundary from Hauptweg Street to the east boundary of the subdivision. Drainage easements should be provided to accomodate reverse grade on proposed cul-de-sacs. An area drainage plan is needed (to include proposed drainage outfall through Tax Par- cel 17-09-202 and Lot 1, Eaglebrook Subdivision). Resolve erosion and sediment control with Public Works Engineering. The subdivision agreement must provide for a storm drainage system with outfall. A subdivision agreement is needed to construct interior streets which will in the most part be through collector streets. Proposed small lots reflect an urban development pattern. Resolve road improvement standards with Public Works Engineering. 7. Pedestrian circulation should be addressed on the site plan.

The Project Engineer, William C. Hagmaier, states existing soils totally preclude on-.site septic waste disposal. Proposed is e community water and sewer system for any deve- lopment on this 50-acre tract of land. The Utility will not accept the sewer distribution network an/or septic tank and leach field for maintenance or opera%ion. The Homeowner's Association will be required to maintain and operate the wastewater distribut:Lon network and ali. other appurtenances required to make a completely workable system.

Weinig (Lot 1, Blk 8 Prator Subd.) Comments: 1. Proposed Planned Unit Developement (PUD) do.eR ~_~9~ the current Comprehensive Plan ~Si~_l~D_qu__ireDents for the area. Proposed PUD does__not_m_ e~t the pending Comprehensive Plan density rea~irements for the area. The site for the septic system leach ~ield is within fifty (50) feet of Goldstream Creek. This creek drains into Rabbit Creek. Goldstream Creek flows through areas with both existing homes and those under construction. At the May meeting of the Rabbit Creek Community Council the developer presented his plan for the proposed PUD (S-6258). After the presentation and discussion there was an informal non-binding vote taken. Of those present and voting (approx- imately 19 present with 4 abstentions) the vote was unanimously against the proposed plan. The purpo~_~ of the Planned Unit Developement (PUD) concept //~_t~t__d~_~(~D~__~ c~]~lg]~ly ~anned. There are many issues which the developer has not planned for and many others which are only treated for the immediate developement needs with no thorough plan for the future· Some of these are listed below: a. The fact that most of the area in the proposed PUD is a lake bed. Every year most if not all is covered by water during the Spring and early Summer months· In 1976/77, a wet year, during Winter-Spring-Summer the area was covered by water in depths up to one foot (a few higher small, under 5000 sq.ft., areas were dry). b. Bird and waterfowl nesting areas c. Emergency replacement of sewer lines, septic tanks, and water source cann_o~ be covered by small homeowners fund (see 1971 Jesse Land Trailer Court episode) d.

OR P%ANNED UNIT DEVELOPMENT/ RESIDENTS PLANNING COMMISSION P.O. Box 4-2950 Anchorage, AK 99509 May 19, 1982 Ms. Sherry Willette Dep&rtment of Planning, Plotting and Zoning Division Municipality of Anchorage ]Pouch 6-650 Anchorage, AK 99502 RE: Case S-6258 and CU82-53-Bavarian Heights Subdivision, proposed PUD ])ear Ms. Willette: I have received notices of the public hearing before the Planning and Zoning Co~nission on May 24, 1982, concerning platt approval and PUD approval of Bavarian Heights subdivision. I live on Prater Street above the proposed development, Lot 1, Block 8 Prater Subdivision. My wife and I are opposed to bot~ the platt and the proposed PUD. I am familiar with the area which is proposed for the PUD. For the past six years, I have skied the area in the winter and hiked it in the summer. Although this spring is much drier than usual, doubtless due in part to the drainage ditches which have been dug on the subject property, the area is a classic wetland in any sense of the term. It is low, boggy, and basically moose pasture and cranberry patch. My opposition to the proposed platt and PUD is as follows: 1. The area is zoned for ]t-6. Zoning for that area was done by petition of the homeowners, and approved prior to the area G zoning for most of the hillside. Such zoning occurred in 1971. or 1972. Homeowners who purchased into this area, particularly relying upon the R-6 zoning which had been generated by homeowner petition, are entitled to that protection. 2. The proposed sewage system for the area, which was represented at the Rabbit Creek Community Counsel meeting on May 13, is to be a leach field approximately 3/4 of an acre in area and twelve feet deep. It is predicated upon taking the standard requirement of a three-bedroom house and its leach field, and multiplying by 75, the number of houses in Ms. Sherry Willette Page 2 May 19, 1982 the proposed subdivision. The Department of Health and Environmental Quality informs me that it has received no infor- mation concerning the feasibility and effect of this leach field which goes beyond the description set forth in the blue PUD booklet, which appears in the Planning Department's file. As you are aware, this booklet in no way addresses the effect of a 75-home leach field, upon the water supply which comes by well either on Mercedes Lane to the west of the development, or along Prater to the east. The effect of the volume of water coming from 75 homes drained into a common pit upon surrounding water systems and surface flow is ~omething which should have been addressed in any proposal for a PUD. It is not something to be governed by conditions subsequent, to be tacked on after PUD approval. The planned unit development should be what its name says: Planned Unit Development. In absence of data to the contrary, the obvious dangers which this volume sewage could create would be that the sheer weight of effluent from 75 houses in a single pit area would spread underground pollution into the adjoining aquifers which serve wells on both Prater and Mercedes, as well as the community well system for the 75 homes to be placed upon the subdivision. A secondary possibility which strongly comes to mind is that once the leach field has been filled'to capacity, there will be overflow and surface flow into Gold Creek, which cuts through the subdivision about a quarter of a mile downhill and in which the proposed Golden View Elementary School will be placed. 3. No data has been submitted concerning the effect which a community well serving 75 houses will have upon the aquifers currently serving residents along both Prater and the Mercedes Hill area. This should be addressed by the developer before a planned unit development is considered. At the Planning and Zoning Commission hearing, there will be testimony by residents of the Mercedes area that nearby subdivisions have already severely decreased the well flow and caused siltation. The effect of this enormous impoundment of effluents should be addressed before the development is given even preliminary approval. 4. Funding for maintenance and capital improvements of a new sewage system when the proposed leech field fills is allegedly to be made by assessments on each lot and governed by the Homeowners' Association in the proposed subdivision. Very little in the proposed covenants, appearing in the blue PUD booklet, address how this is to be funded. As you are probably aware, even the relatively sophisticated Municipal subdivision agreements which place liens upon all lots in a subdivision to secure proper construction of capital 016 Ms. Sherry Willette Page 3 May 19, 1982 improvements are extremely difficult to enforce. As a former assistant Municipal attorney for both the Borough and the Municipality, who has attempted to enforce many of these subdivision agreements, I can only express dismay at the prospect of relying upon a mere homeowners' association, without even right of Municipal intervention for enforcement of these covenants, It brings to mind the specter of the Jesseland Trailer Court disaster which occurred back in Borough days in November 1971. 5. What happens, if on a below-zero winter,day, the residents of the 75 homes awaken to find that the leach field has over- flowed into the community well system, or that as a consequence of malfunction in the sewage system, the entire subdivision is without sewage facilities? The subdivider will long since have taken his profits and gone. This hardly meets the conceptual standards of a planned unit development. 6. The proposed density for the subdivision exceeds that allowable for this area under both the existing Comprehensive Plan and the pending new Comprehensive Plan. 7. The proposed PUD does not appear to.meet the standards required by the Wetlands Plan recently enacted by the Assembly. The proposed PUD seems to iie in area No. 30 of the Wetlands Plan. A requirement, I believe, is thgt development is required to be set forth in a way which will not harm the wetland area. Certainly, placement of houses along the flatland areas of the proposed development does not respect this. 8. The proposed development seems to lie directly in the standing water areas and areas most susceptible to surface and ground water pollution described in pages ].6 and 28 of the Yydrologic Study of the Hillside prepared for the Borough by the United States Geological Survey in ].975. 9. The proposed development does not seem in conformity with the proposed Cluster Plan now pending before the assembly, in that it does not cluster its buildings in the high dry areas, preserving the lower wetlands from predation. 10. At the Community Counsel meeting on May 13, the developer indicated that alii surface run off would be channeled from the 75 homes into a swell which would lead directly down GoId Creek. What effect will this have upon homeowners downstream, particularly in the subdivisions surrounding the proposed Golden View Elementary School, which straddles both sides of the creek? The engineer was unable to give any figures concerning the proposed or estimated amount of run off. 11. Duration of the proposed homeowners' association covenants, 01 ? Ms. Sherry Willette Page 4 May 19, 1982 as set forth in the blue PUD booklet, is 25 years, with an automatic extension of 10 years, unless the homeowners alter this. However, at any time, under the covenants, a majority of the homeowners can change the covenants, including assessment and lien, at any time they want. What protection does this offer either adjacent homeowners or members of the proposed homeowners' association from sewage pollution if the sewage system fails or pollutes the community water system? In the event of failure of the sewage system, particularly in winter months, there would be undoubtedly be extreme political pressure for the Municipality to construct a sewer system from the Golden View areas set forth in the Hillside Wastewater Plan description, to the proposed PUD. This would force a de facto change in violation of the Hillside Wastewater Plan, which proposes to "fix in concrete" the extent of hillside sewers. No PUD should be allowed to "bootstrap" an extension of sewers beyond the limit set forth in the Wastewater Plan which the Assembly approved on May 18. In short, the. developers have not submitted any information concerning the effect of the sewage system for 75 houses upon either the subdivision's community water supply, or upon that of adjoining neighbors' They have submitted no data concerning the effect of their community wells upon the neighbors' water supply. No PUD should be approved, even in concept, until such data is supplied. My best regards, Richard A.

I live across Rabbit Creek Road from the area. I ara concerned about the small size of the lots, some are less '-than 1/3 acre. It has always been my understanding that the btmicipality was in favor of low density housing on the hillside. This subdivision would not conform to that goal. Of added concern is the water usage due to high density housing. We all know the hillside cannot support such an increase in population due to the limited watersupply. The only alternative would be for a water system to then be built to eliminate any problems that would arise from the high.density. And this would mean added costs for all of us. By keeping the iot size qn all the new subdivisions in the hillside area large, we may avoid costly public works systems for some time to come. I am concerned also that the added features that the developer must put in, such as paved streets, is adding to the cost of the lots, thus making him divide into smaller lots. By eliminating some of the unnecessary features of the subdivision development, I believe it would be possible to in- ccease the size of the lots and still allow for proper development and reasonable profit for the developer. I would much prefer to drive over a well maintained gravel road than an inadequate paved road any day. In closing, I want to reiterate my conce~s for the high density development of this subdivision and others on the hillside that are threatening the limited water supply of d~e area. By being more reasonable in the requests of providing added features to these subdivisions you are forcing the developers to offer smaller lots in order to make a profit that will inthe end only cause hardship for all of us. Please maintain the goal of the ~DA by not allowing !~igh density development on the hillside. Sincerely, D.

WARD HIGHWAY · ANCHORAGE, ALASKA 99502 June 21, 1982 Municipality of Anchorage Planning and Zoning Co~ission Members Pouch 6-650 Anchorage, Alaska 99502 RE: Case S-6258; CU-82-53; Proposed PUD. Dear Commissioners: "; Bavarian Heights Subdivision ~/(/ [~?~2 /. 1, / f This letter is written on behalf of our client, Bridger Enterprises, in order to both edify the Planning and Zoning Commission members and to answer questions that have been raised regarding the community waste water disposal system. We are presently asking for final approval on the subdivis- ion and concept approval only for the waste disposal system. At this time, we feel that it is premature to request final approval on the waste disposal system because the actual design of the system and the type of community disposal system has yet to be resolved. We are at this time asking for concept approval based on engineering and geotechnical investigations conducted prior to this platting process. We feel that the research performed to date is sufficient to show that a community waste disposal system is feasible at this location, that it has been reviewed by the responsible agencies, and that the ~oncept of a community waste dis- posal system has been approved by the State of Alaska, De- partment of Environmental Conservation. (See attached letter). The concept of a community waste water disposal system is not new. Many small communities throughout Alaska util- ize ()ne or more variations of a community system. These various systems include large septic tank systems, areated lagoons with pre-treatment systems, sub-surface and sur- ficial sand filters with primary settling tanks, and final-. ly, package treatment plants. The decision as to which type of treatment system to be utilized on each individual site requires a great deal of engineering analysis prior to the final recommendation. However, prior to considering any of these methods, soil analysis, drainage analysis, and engine- ering investigations must be made on each individual site to determine if any of these systems are even feasible. ANCHORAGE EAGLE RIVER HOMER (907) 349-6561 (907) 235-8179 Page 2 S & S Engineers, Inc. Bavarian Heights #1119 June 21, 1982 At the present time, these investigations have been made for the Bavarian Heights Subdivision, and it has been determined not only by our engineers, but also by the State reviewing agency, that a number of these methods of commun- ity waste disposal are feasible for this site. Thus, the concept has been found to be feasible and the only remaining decision to be made is which type of system will be utilized on this site. The final design for any system placed on this. site. will. be brought back before, the Planning: . and Zon-- ~ck_Com~ss~on .f~9or_~approval. Prior to per~.orm~ng any ~ ~,~addit~onal on or off-site engl~neer~ng ~nvest~gat~on ~or determining the type of waste disposal system for th~s sub-- division, ~)ur engineers must know the design parameters under which they will be working (i.e. number of lots, configuration of lots, and the location of the lots). Thus the final approval on the subdivision design will, to a large degree, dictate the type and size of the final recommendations for the waste water disposal system. The successful operation of a waste disposal system entails physical, chemical, and biological processes, each in varying degrees. The physical operations entail the remo- val of particulate matter, oil, grease and floating material, the removal of floating or suspended particles and the concentration of sludges. The chemical processes are normally utilized in more advanced pre-treatment and secondary treatment systems for the recovery of specific ions and compounds, conversion of sludge to ash, the control of pH, and the conversion of soluble compounds to volatile or precipitate form. The biological processes are normally aerobic in nature for the removal of soluble or colloidal organic material. Page 3 S & S Engineers, Inc. Bavarian Heights #1119 June 21, 1982 In Anchorage, the traditional waste water disposal system consists of a two-compartment septic tank~ a deep trench drain system and inter-connecting pipes, clean-outs and stand pipes. Together these components physically remove and biologically treat waste water. The septic tank alone can remove about 30-50% of the wastes if properly main- tained. The soils surrounding the field treat and dispose of the treated water. The first 8"- 10" of soi]. beneath the drain system provides 90% of the biological treatment of the was~e stream. The remaining 10% of the biological treatment occurs within 4.0 feet of the drain system. In the soil, bacteria literally break down the BOD and solids and incorporate them. Pathogens become trapped in the soil by being absorbed onto soil particles or becoming stuck to the microbial slimes laid down by the soil bacteria. Once trapped~ some pathogens die off because of differences in temperature, lack of moisture and food and other causes° Others are inhibited or ki].led by antibiotic, s, given off naturally by soil fungi, and other organisms. Still others are actually preyed upon by soil bacteria and literally eaten. In order for treatment, to be effective, the soil bacteria must have air and sufficient time to do their work. In addition to the requirement of a permeable soil, there must also be at least four feet of unsaturated aereated soil between the bottom of the disposal field and the underlying layer of (a - saturated soil, b fractured[ bedrock, or c- impermeable soil horizoss)~ in order to provide adequate distance for treatment or purification. If these conditions of soil permeability and unsaturated conditions do not exist at the specified location, the physical conditions of the site must be modified or a different treatment process must be undertaken. A typical site modification would be the installation of curtain drains surrounding the waste disposal area to intercept the ground ~ter and carry it away from the area, as is being proposed for the system in Bavarian Heights Subdivision. The systems presently being analyzed for the Bavarian Heights Subdivision waste disposal include septic tanks with sand filter trenches, sub-surface and urficial sand filters with primary settling tanks, or a package treatment facility. Page 4 S & S Engineers, Inc. Bavarian Heights, #1119 June 21, 1982 These systems with the exception of the package treatment plant are variations of the septic .tank and drain field system presently utilized on the Anchorage Hillside. These systems are all recognized as acceptable methods of waste disposal by the 10-State Standards utilized by reviewing agencies in the State of Alaska. One typical system being researched by our sanitary engineers involves a system as shown below. This in no way reflects the final system design. It is shown only as an example. Sedimentation tank + oil and ~rease separator "~1 sand ~ ......tank ~  f~ten =_.] '~/I" ~ In addition, to any waste disposal system proposed for final approval, a~L1 tanks and components of the system will be insulated to further advance the biological treatment. Further, the CC & R's will restrict the builders to install- ation of flow reduction toilets in all residences to cut down both the demand on the water supply and to reduce the amount of wastewater which requires treatment. _ ~p r i m'-'~ry'~"N~_..~.. Deep trench drain system discharge The systems ]Listed above vary in construction costs, engineering complexity, and the required amount of cost for operation and maintenance. These economic and engineering constraints preclude a final determination as to type and size of the waste disposal system to be utilized for this subdivision until such time as we can receive approval for the subdivision. The final approval for the subdivision will set. the design parameters; ,thus allowi~.0U~ engineers to perform further rese~'!i a~ deslgQ analysis to '~ recommend to kile s~ate- Dep~rtment of Environmental Conser- vation and to the Planning and Zoning Commission for final waste disposal system approval. Page 5 S & S Engineers, Inco Bavarian Heights ~1119 The operation and maintenance of the waste disposal system along with the community water system, roads, walking trails, playing fields, etc. will be coordinated through a homeowners association. However, for the operation and main- tenance of the waste disposal system, the homeowners associa- tion will be required to retain a professional sanitary engineer to perform the required maintenance and analysis of the system that will be utilized. The maintenance schedule will be coordinated with the Municipal Department of Health and the State Dept. of Environmental Conservation for their approval. .~he maintenan~ ~on~ract between the ~ homeowners association and the registered sanitary enginee[. ~will~e rb-neg0tiated e~ry yearl. If. &he homeowners a~S~cia~ion de~ires tO change sanitary engineering consultants, they must first notify the Municipality's Dept.~ ~ of Health and Environmental Protection and the State's Dept. of Environmental Conservation for their approval. The developer for this subdivision will initiate this contract with the sanitary engineering firm and will then convey it ~o the homeowners assoc].atzon at their first association meeting. Planned unit developments have been around for a long time and have worked effectively. The essence of the plan-. ned unit: development is that a collective group of home-- owners are financially and legally responsible for amenities in a subdivision other than their own individual lot and home. These amenities can range from something as insignificant as a small park to a subdivision comprised of private streets, tennis courts, swi~ing pool, community water systems, jogging trails, and street lights for which the homeowners are responsible for the care and maintenance. Theoretically, there is no limit to the amount of responsi- bilities that can be assumed by the homeowners association. Also consistent with membership and organization of a homeowners association, it is usually a requirement that each purchaser of a lot, consistent with a mandatory membership in the association, make an initial cash deposit in the form of dues. The aggregate of these dollars in time, collected by the total membership, provides an initial economic: base for the association. Page 6 Bavarian Heights #11].9 S & S Engineers, Inc. June 21, 1982 Starting with this fund and the subsequent contributions made by the homeowners in the form of monthly dues, there is sufficient money to pay the current expenses as well as provide, in effect, a savings account for unforseen contingencies and repair and maintenance of required items. The amenities for this subdivision will be installed by the developer and will be the developer's responsibility until such time as the homeowners association is activated and their first organizational meeting is held. The establishment and their membership in the Homeowners Association is mandatory upon purchase of the lot in this subdivision. This mandatory membership is addressed as part in parcel of the CCR's. At the first association meeting, the developer will present the membership a proposed budget for operation and maintenance. This initial budget is usually adopted by the membersip as well as the by-laws for the association. Typically, the by-laws will provide that there be at least one annual meeting and financial report, at ~ich time a revised budget will he proposed to the membership for adoption. The budget will reflect the estimate of the operating costs for maintaining the amenities as well as a sinking fund reserve for replacement of any items. Based on the initial budget, the dues will then be assessed to the individual membership. It is the intention of the developer to incorporate into the CCR's of this subdivision any reasonable condit- ions that the Planning Commission may wish to impose on the developer and subsequently the Homeowners Association to assure that the maintenance of the amenities of this sub- division are continually maintained in a responsible manner. We look forward to presenting our proposal for this PUD to the Planning and Zoning Commissiouers for approval. If you have any questio,%s concerning this proposal or the engineering requirements, please call o~ect engineer, Bill Hagmaier at 694.-9846.

There appears to be room for the proposed sewage treatment system and alternative systems. However, final approval of the system would require far more information about the impervious strata location, soils type, the soil percolation and permeability, and the subsurface drainage in the proposed subdivision and on the property next to the subdivision. Therefore, the Department can grant approval of the water and sewer system concept only. Sincerely, "Bruce E.
