Serving Anchorage, Eagle River, Palmer & WasilJa / ,[AY 5. tlAMMOND, Governor August 27, 1975 Mr. John Gilva Planning Department Greater Anchorage A~ea Borough 3500 Tudor Road Anchorage, AK 99507 Subject: Swiss Alps Subdivision - Eagle River Area Dear Mr. Gilva: I appreciate the opportunity I was given on August 19th to SuLn~it testimony on the Swiss Alps Subdivision. Because the plattin~ bo~ indicated they only wanted to hear new testimony and ~ecauseb of the time limit imposed I would like to provide ]ny remarks in greater detail. I assume that this type information is desired as representa- tion from the department was requested by the borough adminis~ration. The Borough Planning Department staff did an ey-cellent job in charact- erizing the area and the recommendations of the Department of Environ- menfal Qualtiy were all well taken. The p['esent information provided by the develpper and his method of development lead to the staff's right and proper staff recommendation to deny approval. The Swiss Alps Subdivision lies in a unique and environmentally sen- sitive area with the alpine tundra and steep exposed mountains slopes. The subdivision straddles the headwaters of Carol Creek and the Fire Lake drainages and development will effect water uses as they pe~ ~n to water supply and aquatic life. Fire creek is an al~adromous fish stream. Therefore it is essential to define the areas that are suitable for developments, and to proceed with the development of the project such a manner that the environment is protected and impacted, in the least manner in order to protect the ,people who have existing water uses which this project will affect and to protect tile interests of the people of the State. Because of the unique nature of the area and the nP.r.esent_wate,r use~s,conv£~tionat "design by bulldoze~" technique wil~ on work as nas a±ready been established by past history of the 3ect. Similar projects in similar land have been approved (and we will pay in the future for those)~due to all the environmental factors involved this subdivision should be the point where "planning by past precedent" stops and careful considered decisions based on the project's merits are made. Now I would like to speak to specific areas that concern our Department in the areas of responsibility charged to us by the people of the State of Alaska. Water Erosion anJ S~!taEion ?or the last two yea]Es violations of the Alaska Water Quality Standards and statutes have occured in Carol Creek. This pollution has been directly traced to Thillman Wallace's activities in Swiss Alps Subdivision and his work on the access road. This past year similiar violations occurred in Meadow Creek ~ecause of f.~r. Wallace's activities on the re-alignment of Skyline Drive. (Our concerns on the Skyline Drive project have been voiced verbally and by letter to GAf~B Deoartment of Public Works. While some people ~ould try to separate this project from the subdivision it is diffi- cult to see how a reasonable and logical~man could do so.) It appears that the Public Works Department by not requiring adequate plans and proper construction standards has allowed water and ].and pollution in the Skyline Drive area. It is my opinion that based on the hard evidence provided by the last two years experience that if the usual "development by bulldozer" of a subdivision plan that does not consider the land is pursued then disasterious consequences will result. This will cause permanent irrepairable damages to Carol Creek and Fire Creek and the loss of water supplies for the Carol Creek water system and the Eagle River Carwash. The Department of Environmental Conservation has filed charges for the incidents that occured this year and will continue to do so when is our beIief based on the evidence that violations have occurred. For this reason we strongly support the requirement of a storm drainage plan for present construction work as well as for the completed sub- division to present deaf, age and violation before they occur. Sewage DisDosat Based ~n my experience, observations, and review of the soil l~gs and topography many areas'because of soils and slope are unsuitable for on-site sewage disposal. If these areas are utilized for disposal of sewage using on-site systems then the pollution of Carol Creek by pathogenic brganism resulting from human fecal contam- ination is a foregone, conclusion. This will result most importantly _in the contamination of the existing Carol Creek water system and sub- ject those consumers to the whole spectrum of diseases present i~ the intestines of humans such as typhoid, hepatitis, and other gastro- intestinal diseases. The first installation of an on-site system in the drainage of Carol Creek will subject the users of the present Carol Creek water system to the disease potential cited above. No compentent health authority would ever permit on-site sewage disposal in the drainage serving a water supply such as the one that exists in Carol Creek. If development is to be allowed at all in the drainage then sewage should be either transported out of this particular drainage disposal or.the developer should work out another source of supply such as a well for the present consumers as a trade-off in the name of jus- tice. It is my opinion that if the use of on-site systems are allowed in this drainage through the approval of a poor subdivision plan the developer wil'l be assured of serious legal action not only for pollution of State waters, but more importantly contamination of a public water supply. For your informa~on and use I am enclosing a count decision for a very similar case which graphically illusnrates the liability that a developer incurrs when he procedes after notice that problems will result because of his action. The Department would expect to fully use this important legal precede~t if prevention is not possible- thyough wise land use. The slope .of the land is very important in sewage disposal. Too high a slope may place such a hydraulic gradient on the sewage aS it moves through the soil that little 'treatment is affected. The grad- ient may become so steep that sewage surfaces on the slope itself. Many sewage disposal system concentrated on small lots on a mountain side provide the potential for predictable pollution of ground and surface waters in lower elevations. ~rainagq The peaty soils of the bowl area of Swiss Alps Subdivision are very extensive and act as a sponge for ground water retention in the Carol Creek drainage. The undisturbed conditions of this area slows down the discharge of water from the drainage insuring ~ significant flow in Carol Creek at all times of the year. This is important, not only for Carol Creek, but also to Fire Creek to which it is a major tributary. It was very evident that the developer's presently existing drainage efforts have caused higher levels of water in the creek than normal. While this is good on the surface it is entirely possible that during months of low historical precipitation that flows may' drop to very critical levels which would not permit the water supplies to have sufficent water and affect aquatic life in this creek and Fire Creek. Again the developer has the very likely potential to affect the existing water uses and he should provide acceptable substitutes to the -two existing major users of the stream. Also the drainage scheme will have the predictable effect of concentra- ting the inadequately treated sewage effluents from the unsuitable soils and conducting them'eventually to Carol Creek. This drainage to lower the water table greatly increases the potential for fecal pollution of Carol Creek drainage. Drainage of certain lands for residential construction can be doubtful process even where public sewers are pro- vided, a~ the potential for flooding of subsurface portions of stzuctures when the drainage scheme is not sufficient to handle the subsurface waters in years of high recharge or when the scheme fails due to plug- ging or mechanical failures of components. Where public sewers are pro- vided "only" damage to. structures may result and sewer flows increase. When on-site sewage disposal system are used then failure of the systems occur and health hazards and pollution result. Great care and expertise is hence required both in design and construction. Wind Erosion Due to the removal of the orginal orgahic surface soils in portions of the subdivision, wind erosion is evident. It is extre- mely important that careful attention be paid to require revegation on disturbed ~ortions such as cuts, fills, and other denuded areas. If these areas are not properly revegetated then the continued wind ero- sion will help lay. the potential for water erosion by inhibiting the ~egetative cover. Dust problems are also very likely from this source as well as traffic flow in the subdivision. Something that is disturbing to me was an inference by the Platting Board was that this subdivision should be approved because of others like it have in the hillside area of the Anchorage Bowl. I have made mistakes which have flowered and produced undesired results. I daily work correcting m~stakes that have been made because of unwise land use. People are forced to spend unreasonable sums and do very uncon- vential and costly thiDgs to attempt secure water and provide safe sewage disposal ~n areas that the land cat provide neifher. Often the house is constructed and people's life savings are at stake. Waivers of serious consequence are sought from existing laws for lots which should not exist in the first place. My point is that at a point in time this must be stopped and future approvals given on up to date standards. Projects should not be approved because "ones like it have'~, but on the basis of its merits considered against updated standards which must from time to time change based on newer technology. In line with the above throught one platting-board member stated "other agencies should excerise their own jurisdiction[ That was exactly the reason for my presence at the hearing on Swiss Alps. Irregardless of any laws our Department may have, if unsuitable land is approved for subdivision then punitive measures must be taken by regulatory agencies such as DEQ and our Department instead' of preventative measures. Pre- sently in the State, Borough Platting authorities possess the most significant force and in truth the only real control in land use. While there is an Alaska Pipeline and petroleum development in the Gulf of Alaska may take place, the real impact on this State and its environment is the population that results and how these PeoPle affect the-environ- -ment. In the flurry over caribou and tundra %he~ef~ect of the people on the populated areas of the state and the land, water, and air in these areas have been largely ignored. ~We hope to prevent these pro- blems and "exercise our jurisdiction" by providing input %o the groups who have authority and po~er to see that impact~s--minimized an~ deve- lopment takes place in ~ manner which protects~ our state's environment in the areas where we live, work, and spend the majority of out'time. We have the following specific recommendations for the Swi~s Alps Subdivision: 1. No lot shall be less than 5~acres~ To determine the lot size on sewage disposal capacity alone in the face of other serious environ- mental problems is a fallacy. For an education one should review the way 2 1/2 acre lots have been utilized in"A-he Eagle River, Birchwood, and Chugiak area and see how much disturbance of vegetative cover has taken place in these much less fragile areas. No five acre lot should be resubdividable. 2. Ail five acre lots shall contain slopes and approximately 20,000 square of for sewage disposal. a home site with appropriate land of less than 25% slope 3. No On-site sewage disposal systen~s s~ould be permitted in the Carol Creek drainage portion of the subdivision until appropriate measures have been taken to replace the.existing Carol Creek Water System with a.state approved system. · 4.. A 50 foot wide publicly owned greenbelt shall be provided on each side of the major streams .to preserve the existing high water quality in the Carol Creek drainage. · ' e 5. Only areas which have sultaD1 homesites with sewage disposal areas of proper slope (C251), suitable soils, and proper distances to bedrock and the water table shall be developed. Great care must be taken to define bedrock areas to prevent possible "p~rching" of sewage effluents .and consequent pollution. 6 Areas with little or no potential for ground water for water · water. As the developer has dril].ed supply shall be served with public several wells in the subdivision he should be well on his way to fining these areaS of low potential. · 7 A detailed s~orm drainage plan prepared by a competent engineer shall ~e prepared to cover handling of snowmelt, rainfall and draina~'e . ' able channel liDing~ ~hall be used runoff. In dlsturbed~ ~r~as s~s such areas-~ ~prOV~slOn shall~.b~ uct concentrated flo~ acz~ ~ ~ ~i~s and a ~aintanence p~o~e~u~ cond ~ ~ei~ned sedlmentat~O~ ~ our for propez*3 ~ provided for their operation. This plan will require approval by Department. This approach is required to protect the existing high water quality in the Carol Creek ~rainage. 8. All denuded and disturbed areas shall be revegetated according to plan approved by DEQ in conjunction with ADEC. Minimum disturbance of vegetative cover shall be required of lot owners through appropriate agreements. It is felt that these eight reeow~endations are the very minimum to properly take care of the areaS of the environment with which~.we are charged to protect~ I do not feel these are in conflict with the original staff recomm~endations which were well thought out and 'entirely my considered opinion that no person should judge valid~_ ,~It is also project ff,there investigations have been limited the merits of this to observation of the scar visible from the Glenn Highway and have never set foot on the property itself. The Board Members should be encouraged to make a site inspection before a~y decision is made. ·~ Mr. Roguska ~equested copies of some of the photos I presented at the hearing for the record. If you will stop by our office in Room 1206, MacKay Building and select the ones you want we will provide them at cost. I appreciate t~e opp°~t~tO make these comments, thank you for your patience in reviewing them, and respectfully request they receive con- sideration. Sincerely, Kyle J.
