GREATER ANCHORAGE AREA BOROUGH PLANNING ~ND ZONING COMMISSION AiqD REGARDING THE PROPOSE R-6 ZONING ON YOUR PROPERTY IN AREA "G". Dear Mr. Mathis~ Mrs. Sturgulewski has asked that I reply in her behalf regarding the above mentioned letter. As you have already been notified', the Plam.~]ng and Zoning Commission will be holding a public hearing on April 27, 1972 to consider what is commonly called the Area "G" zoning program, wherein your property is proposed for R-6 zoning along with a majority of other properties in the same vicinity. The Planning Commi'ssion's action in initiating an extensive amount of R-6 and some R-7 zoning in Area "G" was prompted, in part, by new information and standards regarding the public health needs associated with on site sewer and/or water facilities. I am certain the members of the Planning Commission were unaware of the events that have taken place regarding a public water supply to serve your subdivision at the time.it was initiated for R-6 zoning. Therefore, I would request that you appear at the hearing on April 27th and personally make these facts known to the Commission. in addition,. I would suggest 'that you-discuss this matter with the Borough Department of Environmental Quality so that they can provide the Commission with a recommendation regarding any environmental health hazards associated with the development of each lot in Heritage H.~ights Subdiyjsion with an on site sewage disposal system. Since the purpose of the Planning Commission's hearing on the 27th is to determine whether or not the zoning distmicts proposed are appropriate for each specific parcel of property, it is reasonable to assume that the Commission may make changes in the Area "G" proposal, provided facts can be presented to justify these changes. Mr~ L.0. Mathis Page 2 April 18, 1972 Once the Planning Commission has concluded its hearing, it will then forward its recommendation on Area "G" to the Borough Assembly. The Assembly, like the Planning Commission, will also hold a oublic hearing on this zoning program prior to adopting an ordinance. If you are not in agreement with the Planning Commission's recommendation to the Assembly, you may file, by letter, a formal protest to that recommendation. If 20% or more of those persons who o~ proposed R-6 property within the G-2 Area.actually protest the proposed R-6 zoning, then it will require a 3/4 majority vote of the Assembly rather than a simple majority vote to adopt .the R-6 zoning within G-2. I hope this information satisfactorily answers your inquiry. Please do not hesitate to contact myself or Mr. Dean Blount of the Planning Office if you have any further questions. Sincerely yours, Donald G. Beckord Current. Planning Administrator DGB'/lkm · cc: Mrs. Arliss Sturgul~wski Department of Environmental Quality YUKON DEVELOPMENT CORPORATION Mrs. Arli~s Sturgulewski Chairman Planning Commission Greater Anchorage Area Borough 3500 Tudor Road Anchorage, Alaska Dear Mrs. Sturgulewski: I .am very concerned to find that the Ileritag_~Heights Subdivision located' on tile southeast corner of the intersection of Bi-----~ch-an--~--A-bbott Roads is proposed to be zoned R-6. This would negate all the 'work that has beeh accomplished on tile sub- division to date. It has taken me nearly two years to conclude arr'angements to obtain a public water supply from Central Alaska Utilities using the water sys'tem which is located at the Hanshew School. Although the delay has been costly, we determined that a p~blic water supply should be provided in order to properly develop the subdivision. The street right-of-ways have been cleared and stripped of frost susceptible material. Seven test pits were dug and percolation tests were made to assure that no prob- lems would be encountered in designing proper septic tanks and leaching pits. The design oF the streets has been completed and includes not only asphalt paving but curb and gutter as well ~ire hydr~n.ts !las · ' "~~rnund e ectrical -nd telephone serv~d$¥ ,n-li The excess timber has been hand cuz Trom most of the lots in order to preserve the existing ground cover. The lot sizes range from 16,752 square feet to 22,645 square feet and with the encountered so'il conditions are more than adequate for septic sewage systems when used in conjunc- tion with a public water supply system. In other words, no effort was spared to develop a quality subf]ivision even though the existing Borough regulations were less stringent. Within the past month, after learning that I could count on a public water supply this construction season, I }lave presold four of the lots contingent on providing the utili~ies by August 31, 1972. I am presently negotiating for a land development loan which t hope will not be adversely affected.by this proposed zoning change. From the Zoning Implementation Program, Flap G-l, I notice that subdivisions located to the. south of Abbott and west of Birch Road are zoned R-lA. This is tile zoning · which was originally proposed and later shown on your maps for the Heritage Heights Subdivision. I'would appreciate learning why Heritage Heights was not included in this zoning this time. If there is any way that I can remove this complication immediately~ I would appreciate knowing the procedure because I am afraid that this will adversely affect my application for a land development loan. Your prompt attention on this matter will be appreciated. Sincerely you rs ~2 ~ ,_. o. Yukon Development Corporation 1970 ;Ir.

Enclosed please find a "Preliminary Subdivi~ion~ch shows the loca- tion and logs for seven test pits. Percolation tests were run in four of the test pits with varying results from 2.5 minutes/inch to 16 minutes/inch. In my opinion, the fact that the material permeability varies widely confirms our earlier conversation in which we discussed the adviseability of digging the core of the pit and then, by field inspection, determining what percola- tion area is required. This is the procedure that I propose to utilize in assur- ing that the residences in Heritage Heights have pits with adequate percolation areas. As you will recall, I investigated the possibility of connecting the Heritage Heights Sewer into the system of the Hanshew School Complex. Since the line to the school was sized as a lateral to pick up only the school facility, and since a deep draw runs between the school complex and Heritage Heights, over 3000 feet of line and a lift station would have been required to make this connection. Obviously, economics dictate that this is not feasible for a fifteen acre subdivision. F. lt. A. has requested that I obtain a letter from you discussing your opinion as to the feasibility of connecting the Heritage Heights Subdivision to a public sewer. Also, if you concur with my proposal to base the seepage pits design on field inspection and avoid many costly percolation tests, I would appreciate your including a statement of this fact in your letter. Your consideration and opinions will be appreciated. Sincerely yours, PAN AMERICAN CONSULTING ENGINEERS LOM:ma L. O. Mathis, P, E. 1872-E Chief Engineer YUKON DEVELOPMENT CORPORATION 645 "G" STREET. SUITE 201 ANCHORAGE, ALASKA TELEPHONE (907) 272-91~1 %ebruary' 20, 1973 Mr. Jerry Reinwand Department of Environmental Conservation Pouch 0 State of Alaska Juneau, Alaska 99801 Dear Mr. Reinwand: Enclosed please find a record plat of the Heritage Heights Subdivision which was approved on January 20, 1970 by the Greater Anchorage Area Borough. The average size of these lots is slightly over 19,000 square feet. The subdivision has a public water system which is operated by the Central Alaska Utility Company using the well at the Service Hanshew School as a water source. This distribution system was installed last summer and was approved by both the GAAB and your local state office. Although I attempted to connect into the sewer line serving the school complex, this was not poss- ible because the lateral to the school was sized only for the school load and a ravine between the subdivision and the school would have required a lift station. The size of this subdivision would not support the cost of a long main and the lift station. Also, because of the numerous test pits which I dug on the property, I was sure that the soil conditions were satis- factory for on site sewage systems. During the construction of the water system, the ditches were excavated 12 feet below the road grades which in some cases were more than 10 feet below the original ground. In the entire ditch length which forms a loop around the center of the subdivision, not a drop of ground water was encountered. Although there are a few small pockets of wind blown silt, generally the subdivision is underlain with coarse gravel which provides excellent under- ground drainage, The terrain slopes down to the north and west at an aver- age grade of approximately 6%. The 100 foot road right-of-ways located to the west and north of the property provide additional absorption area for the subdivision. A 500 acre park is located to the north of the subdivision. The lots located to the south of the subdivision are 45,000 square feet lots having both on site water and sewage systems. Therefo~ this area will never be a high density location. To my knowledge, Heritage Heights is the only subdivision in this immediate area which has a public water system, natural gas, underground electrical, paved streets, and curb and gutter. The subdivision is approved by FHA. All but six of the lots have been sold, mostly to individuals planning their own residence. The price range of the houses will run $65,000 and up, Lots 13, 20, and 23 have houses under construction at the present time. A house for .Lot 22 was being processed for a loan prior to your emergency regulation. Con- struction was planned on practically all the lots for the coming construction season. February 20, 1973 Mr. Jerry Reinwand Your emergency regulation has stopped the planning for construction on 12 lots that I know of. Since it is very desireable to complete house plans, obtain loans, select contractors, and apply for building permits well before the Spring breakup, I respectfully request a variance for this subdivision which in my opinion does not have a problem for on site sewage systems now nor when it was planned over three years ago. Your prompt attention on this request will be appreciated. Sincerely yours, L. O. Mathis, P.E. Yukon Development Corporation CoG, Mr. Rolf Strickland Mr. Kyle Cherry Hr. L. O. g~thts, P. E.

The Contractor shall take adequate and proper measure to inform himself as to the existence and location of airy and all underground utilities apt to be encountered during his operation and shall protect the same against damage. If any oi,pes~ conduits, poles, wires, or apparatus are damaged, the Contractor shall inm~.diately notify the Engineer and the utility compaq'if involved. The damage shall be repaired by the authorities having control of same at the Contractor's expense. Whenever the construction is within the area of other public utilities (water, sewer, electrical, telephone, or gas, overhead or underground) shown on the plans and the utility has to be temporarily raised, lowered, guyed, shored or braced, or otheri~ise protected during construction, it shall be done at the exmense of the Contractor and shall be included in the Contractor's bid price for that item of work in place. If construction endangers support of telephone or power poles, the agency having jurisdiction shall be notified and the poles shall be adequately protected by the utility at the expense of the Contractor, before construction is started. The utility company will make available to the Contractor charges that will be made for shoring and guying poles and these charges will be considered by the Contractor in the preparatio~ of his bid.

Tile requirements and insCructions given in the rer.!aining suo-~]aragrapns of this Paragraph A. 1.18 shall apply only to work performed in a public right- of--way or easement and shall not apply to work clone on a building site of a structure. Prior to awardinq the contract, the Owner .rill notify all affected Jtilities to move such of ~heir installations as would be '.,ith~in the confines of ti~e finished improvement. This kind of work by lhe utilities will noFmall7 have ~een accomplished in most instances before the Contractor is worki~]g at points affected. Under some circumstances, however, the work of the utilities may have to be performed during the construction. It shall be the responsi- bility of the Contractor to coordinate his work with that of the utilities ~ in such a manner as to cause the least possible interference. It is the intent of the plans that no utility,, public or private, witi~in right-of-way or easements shall be moved to accommodate the Contractor's equipment or his method of operation when such utility does not interfere with the improvement under construction unless the cost of such removal and replacement shall be at the expense of the Contractor. T~e Engineer shall deter!nine if an existing u~ility must be moved and the utility would then be moved by the utility conpany having jurisdiction over the same at no charge to the Contractor. The EnQineer will not determine that an existing utility must be moved unless it cannot be quved shored braced or bypassed by ordinary procedures. - .... , Method of Servi Any written notice to the Contractor which may be requisite under these specifications may be served on hii~!~ either personally, or by mailing, or by leaving at his last address known to tile Owner. Any written notice to the Owner which may be requisite under these specifica- tions may be served on the Engineer, either personally or by certified mail.

After the required test pressure has been reached, the pumping will be terminated. If the pressure (150 psi) remains constant for fifteen (15) minutes without the aid of a pump, the water line will not be subjected to any further hydrostatic test, If the pressure (150 psi) does not remain constant for fifteen (15) minutes, a leakage test will follow. All valves within the section of line being tested will be closed and reopened as directed by the Engineer, after the required pressure (150 psi) has been obtained and prior to the fifteen (15) minute constant pressure test. (c) Leaka~._e' Test. Tile duration of each leakage test shall be at least ~-o--(-~] hours; and during the test, the main shall be subjected to a constant pressure of 150 pounds per square inch for two (2) hours. Leakage for any newly laid pipe or any valved section thereof is defined as tile quantity of water that is necessary to maintain the specified leakage test pressure after the pipe has been filled with water and the air is expelled. No piping installation will be accepted until the leakage is less than tile number of gallons per hour as determined by the formula: L = 0.00027 ND ~'-~-- which equals the allowable leakage in gallons per hour per 100 feet at 150 pounds per square inch test pressure and shall be as follows: P_ij~_~ia. me.t_e_r (_I.!~!~_es) Gal 1 ons Per Hour 6 O.1191 8 O. 1588 l0 0.1986 12 O. 2383 14 O. 2780 16 0.3177 18 0.3574 20 0.3972 Leakage test on asbestos-cement pioe shall be done only Iipe has been filled witll water for a minimum period of 24) hours.
