(2) Selected Backfill Material Selected backfill material in the initital backfill zone as hereinafter defined for sewer pipe shall contain no piece of material larger than three (3) inches for all sizes of pipe. (3) Water for Backfill It will be the Contractor's responsibility to make all necessary arrangements for a source of water during all periods of construction and to make all arrangements for delivery of the water to the trench side. b. Sewer Pipe• (1) General The Contractor shall use polyvinyl chloride (P.V.C.) sewer pipe or a pipe having a recommended Chezy Coefficient of 140 or greater. The pipe shall be of the diameter shown on the drawings and the physical properties specified below. (2) Polyvinyl Chloride (PVC) Pipe and Fittings (a) Compound The pipe and fittings shall be made of polyvinyl chloride (PVC) plastic which shall meet the requirements for a Class 12454-B compound. The minimum physical properties and chemical resistance of the PVC compound shall meet the requirements of ASTM D-1784 for a Type 1, Grade 1 compound. (b) Gravity Sewer Pipe and Fittings Polyvinyl chloride (PVC) gravity sewer pipe and fittings shall be Type PSP meeting the requirement of ASTM D-3033. All pipe shall be SDR 41. (c) Marking All pipe shall be marked at intervals of no less than five (5) feet with: Normal pipe size SDR number Type Appropriate ASTM number Working pressure. (d) Couplings All polyvinyl chloride (PVC) sewer pipe shall have an integral belled gasket pocket coupling at one end.. The gasket shall fit snugly into the space between the under lapping spigot and the gasket retaining pocket to form a flexible watertight seal. (e) Gaskets The surface of the gasket shall be smooth and free of pits, cracks, blisters, air marks and other. -imperfections that would impair its use. Gasket strength shall be such that the gasket can be strentch to 150% of it's normal circumference without harm to the gasket. (f) Pipe Length Normal lengths of pipe shall be twenty (20) feet. Other pipe lengths shall be provided if required. (g) Fittings Fittings such as saddle outlets, elbows, tees, wyes, etc. shall be of the same material and compatible in con- struction to the adjacent.pipe. (3) Other than PVC If the Contractor wishes to use other than PVC sewer pipe he shall submit to the Engineer the pipe manufacturers information relative to flow characteristics, load carrying capabilities, and other test results which may be deemed necessary for approval by the Engineers. The Engineers shall notify the Contractor, in writing, within 7 days of receipt of said information as to the acceptability of the pipe. -2- i 0 c. Closure Collars Closure collars shall be constructed of concrete having a minimum twenty-eight (28) day compressive strength of two thousand (2,000) psi. Closure collars shall -be used to make connections and pipe joints when conditions prevent the use of the standard rubber-gasketed joint furnished with the pipe. 3. Workmanship_ a. Excavation and Backfill (1) Clearing the Right of Way Where clearing of the right of way is necessary, it shall be completed prior to the start of the trenching. Brush shall be cut as near to the surface of the ground as practicable and removed to an approved disposal area. The Contractor shall observe all Federal and State laws relating to hauling permits and local regulations relating to burning and/or otherwise disposing of such materials. Under no conditions shall excavated materials be permitted to cover brush prior to clearing and removing same. (2) Obstructions This item shall refer to obstructions which may be removed and do not require replacement. Obstructions to the con- struction of the trench such as but not limited to tree roots, stumps, abandoned concrete structures, and debris of all types shall be removed by the Contractor at his own expense without additional compensation from the Owner. The Engineer will, if requested by the Contractor, make changes in alignment to avoid major obstructions if such alignment changes can be made without adversely affecting the intended functioning of the facility. The Contractor shall pay all additional costs to the Owner resulting from such alignment changes. (3) Trenches Trench excavation shall be to line and grade as established by conventional practice or as ordered by the Engineer. The bottom width of the trench shall not be less than twelve (12) inches or more than twenty-four (24) inches wider than the outside diameter of the pipe to be laid. The trench shall be adequately and properly timbered or shored. The Contractor shall be responsible for the adequacy of all shoring, sheeting, and bracing. Where the bottom of the trench encounters cement gravels, stones, or boulders, excavation shall extend to four (4) inches below the line of pipe bell and then be backfilled and tamped with approved sand or. earth to form a cradle for the pipe. Except where rock, boulders, stones, or cemented gravels occur, trench excavation shall first be made to a plane one (1) inch above the finished grade. The final or finished excavation including bell holes shall be made just ahead of pipe laying. All irregularities in the trench bottom shall be removed by appropriate excavation or backfill. Bell holes shall be excavated for bell and spigot pipe of sufficient dimensions to permit pipe laying to work freely and to positively avoid the bell carrying any weight or loading stresses and so that the pipe shall have a firm bearing of not less than three-fourths (3/4) of the length of the barrel. Trenches shall be kept free of water until the pipe is laid, joints completed, and thereafter until jointing material is adequately set. M-0 (4) Location of Excavated Materials During trench excavation, the Contractor shall locate the excavated material so it will not completely obstruct a traveled roadway or street. Unlesst otherwise approved by:the Engineer, all streets and roadways shall be kept open to at least one-way traffic. (5) Removal of Water The Contractor shall provide and maintain ample means and devices with which to promptly remove and dispose of all water entering the trench excavation during the time the trench is being prepared for the pipe laying, during the laying of the pipe, and until the backfill at the pipe zone has been completed. The Contractor shall dispose of the water in a suitable manner without damage to adjacent property. (6) Initial Backfill After the pipe lengths have been jointed and jointing material has properly set to the Engineer's approval for backfilling, the bell holes and sides of the .pipe shall be carefully backfilled and thoroughly compacted with approved tampers, supplemented by "walking in", and with approved backfill material of sand or earth in layers not to exceed six (6) inches in thickness. The initial backfill shall be continued in layers of not to exceed six (6) inches in thickness until the backfill is twelve (12) inches above the top of the pipe using approved backfill material of sand or earth. Under no conditions will puddling be permitted for this intital backfill. (7) Trench Backfill After initial backfill, trenches may be backfilled with the material excavated provided rocks and other deleterious materials, if present in the excavated material, are removed. Material containing frost shall not be used for backfill. The firstone (1) foot of backfill above the initial backfill shall be given careful attention as to composition. The entire backfill is to be puddled or firmly compacted as hereinafter stipulated or by other methods if approved by the Engineer. (8) Puddling All trench backfill for this project shall be puddled. Puddling shall be accomplished by first backfilling the trench grade of the travel way, then water shall be added -to the trench for its entire length until it is evident that the backfill material is saturated with water. Additional backfill material is to be added to the trench to compensate for the settlement incurred by the puddling in such an amount so as to bring the final backfill material to within twelve (12) inches of the finished surface of the travel way. The excess excavated material remaining alongside the trench is to be removed from the public right of way and disposed of by the Contractor. The remaining twelve (12) inches of the unfilled trench is to be backfilled in accordance with street surface repair as hereinafter specified or with topsoil material where street surface repair is not required. (9) Excess Excavated Material All excess excavated materials. from excavation and backfill operations shall be hauled and disposed of by the Contractor at locations approved by the Engineer and/or Owner. (10) Surface Runoff Water The Contractor shall at all times protect any open trench from the entrance of surface runoff water due to storms, irrigation, or mishandling of puddling or compacting water by any contractor within the work area. In the event that water does enter a -4- trench, the Engineer may require the Contractor to furnish, at no additional cost to the Owner, the required foundation stabilization gravel to provide a suitable foundation for laying the pipe. b. Sewer Pipe (1) Preparation of Sewer Pipe All pipe and fittings shall be carefully inspected before being laid, and no cracked, broken or defective pipe or fittings shall be used in the work. The ends of the pipe shall be cleaned with a brush, washed, and thoroughly scrubbed where necessary to remove dirt or other foreign material. Extreme care shall be exercised to insure'thatthe inside surfaces of the bell are smooth and free from any projections which would interfere with the assembly or watertightness of the joint. (2) Handling Proper implements, tools, and facilities shall be provided and used by the contractor for. the safe and proper protection of the work. When such damaged pipe cannot be repaired to the satisfaction of the Engineer, it shall not be used in the work. The pipe shall be carefully lowered into the trench to prevent damage to the pipe. Under no circumstances shall pipe be dropped or dumped into trenches. Foreign matter and dirt shall be removed from the inside of pipe before it is lowered into the trench, and it shall be kept clean by approved means during and after laying. (3) Line and Grade Maximum deviation from true line or grade as established by the Engineer, shall be three -eights (3/8) inch. Measurement for grade shall be taken at the pipe invert - NOT AT THE TOP OF PIPE - because of permissible variation in pipe wall thickness. Grade shall be established from batterboards set in the trench at maximum fifty (50) feet intervals. A minimum of three (3) sets of batterboards with string line shall be maintained ahead of the pipe laying at all times. (4) Tests and Inspections (a) Test Specimens Test specimens in the amount set forth in the applicable ASTM Specifications shall be furnished the Owner at no charge. (b) Pipe Inspection Specimens for absorption and strength tests may be selected bythe Engineer in accordance with the applicable ASTM Specifications from pipe in the pipe manufacturer's yard or at the point of delivery to the Contractor. Tests may be performed at the Contractor's expense on the specimens selected. The provisions of applicable ASTM Standards shall apply, except as modified herein, in regard to the number of tests made, the evaluations of such tests, and the rejection or acceptance of pipe. The Owner reserves the right to approve the testing agency, and the:Engineer's evaluation of the results of such tests shall be final. -5- (5) Air Tests for Sewer Lines (a) Amount of Testing The Contractor shall conduct air tests on all sections of sewer lines after backfilling and settling of the trenches and shall furnish all equipment and personnel required to perform the test. i To facilitate the detection of any leaks that may have occurred during the pipe laying operation, the contractor may, at his option, air. test any or all of the sewer lines prior to backfilling. However, this test will be in addition to the required air test following the backfilling and settling of the trench. (b) Leakage Allowance The leakage allowance requirements of the air test shall be considered satisfied if the time required in seconds for the pressure to decrease from 3.5 pounds per square inch (psi) to 2.5 psi is not less than three (3) minutes fifty-seven (57) seconds. (c) Testing Procedure The low pressure air test is a test which determines the rate at which air under pressure leaves an isolated section of pipeline. This rate indicates the presence or absence of pipe damage and/or pipe of poor quality. The test procedure is des- cribed as follows: Step 1. The section of pipe to be tested is plugged at each end. The ends of all branches, laterals, and wyes which are to be included in the test are sealed or plugged. All plugs shall be carefully braced to prevent slippage and blowout due to internal pressure. One of the plugs provided must have an inlet tap or other provision for connecting an air hose. Step 2. Connect one end of the air hose to the inlet tap on the plug and connect the other end of the hose to portable air control equipment. The air control equipment shall consist of pressure guages and valves used to control the rate at which the air flows to the test section and to minitor the air pressure inside the pipe. The air control equipment can then be connected to a source of air supply such as a portable air compressor. Step 3. After the air hoses are properly connected, inject air into the test section. Monitor the air pressure so that the pressure inside the pipe does not exceed five (5) pounds per square inch, gage, (psig)• Step 4: When the pressure inside the test section reaches 4.0 psig throttle the air supply so that the internal pressure is maintained between 4.0 and 3.5 psig for at least two (2) minutes. These two (2) minutes allow time for the temperature of the air to come to equilibrium with the pipe walls. Step 5. After the temperature has been allowed to stabilize for the two (2) minute period, the_air supply should be disconnected, and the pressure allowed to decrease to 3.5 psig. At 3.5 psig a stopwatch is to be started to determine the time required for the pressure to drop to 25. psig. -6- The section of pieline being tested shall be considered acceptable if the time required in seconds for the pressure to decrease from 3.5 to 2.5 psi is equal to or greater than three (3) minutes fifty-seven (57) seconds. (6) Thrust Blocking and Closure Collars The thrust blocks shall be poured against undisturbed earth. No concrete shall be poured until all water has been removed from the excavation. Suitable forms shall be constructed to obtain shapes that will provide full bearing surfaces against undisturbed earth, as indicated on the Plans.' The thrust blocks shall be cured three (3) days before air tests are conducted. Care shall be taken during excavation not be over -excavated in the areas where thrust blocks are to be poured. Before the closure collars are poured, the pipe shall be washed to remove all loose material and soil from the surface on which the concrete will be poured. The entire collar shall be made in one pour, and care shall be exercised to prevent concrete from entering the joint. The collars shall be cured seven (7) days by keeping the surface wet. Closure collars shall be used only when approved by the Engineer. B. MANHOLES 1. Scope This section includes the work necessary for the construction of the precast manholes, including but not limited to the additional excavation and backfill required; concrete and forms; furnishing and placing concrete precast sections, concrete cones, pipes, and fittings; cast iron frames and covers; dust pans; and all incidental and related work. The Contractor may, at his option, use poured -in-place type manholes provided all details of the construction are approved by the Engineer. 2. Materials- . a. Concrete Concrete used in the construction of the manhole base and other structures specified shall be so proportioned and mixed as to meet a twenty five hundred (2,500) psi compression test after twenty- eight (28) days. There shall be a minimum of five (5) sacks of cement per cubic yards of concrete. Water sahll be provided by the Contractor. (1) Forms Forms for manhole bases and portions of structures below grade shall be matched boards, plywood, or other form material approved by the Engineer. b. Precast Manhole Sections Precast concrete sections for manholes sall be minimum forty-eight (48) inch diameter reinforced concrete pipe, Class II conforming to ASTM C 76, with threaded requirement that the reinforcement shall be four and one-quarter (4 1/4) inches. Cones shall be concentric with wall thickness and reinforcement similar to that of manhole pipe sections. The tops and bottoms of cones shall be parallel. -7- 0 c. Mortar Grout The joints for the precast concrete manholes shall be made with cement mortar or grout consisting of one part cement to two parts of clean, well -graded sand which will pass a one -eights (1/8) inch screen. Admixtures may be used not exceeding the following percentages by volume of cement: hydrated lime, five (5) per cent; diatomaceous earth or other inert materials, ten (10) per cent. The consistency of the mortar shall be such that it will adhere readily to the pipe. No mortar shall be used when its ingredients have been mixed for a period greater than thirty (30) minutes. d. Manhole Extensions The precast concrete grade rings used between the top of the cone and the base of the manhole ring shall have a minimum thickness of two (2) inches and shall be of standard construction. The rings shall be approved by the Engineer before installation. In general, manhole extensions having a minimum heighth of six (6) inches and a maximum heighth of eight (8) inches will be used on all manholes except in cultivated fields and on very shallow manholes or in other locations where a subsequent change in existing grade may be unlikely. e. Manhole Frames, Covers and Dust Pans All manhole frames and covers shall be of the size and shape as shown on Ada County Highway District's Drawing No. 330 or approved equal. A cast iron dust pan shall be furnished with each ring and cover. 3. Workmanship a. Concrete Base The concrete base for the precast manhole shall be constructed so the first section of the precast manhole has a uniform bearing throughout the full circumference of the manhole wall. Sufficient mortar shall be deposited on the concrete base to provide a watertight seal between the base and the manhole wall. b. Placing Precast Manhole Sections The joints for the precast concrete manholes shall be made of cement mortar consisting of one (1) part cement to two (2) parts sand. The walls shall be constructed true to line and grade, as established by the Engineer. Mortar shall be placed on the groove of the lower section of pipe prior to placing the next section of pipe. The entire joint shall be completely filled with mortar and troweled to a smooth finish. c. Manhole Invert The invert of the manhole shall be constructed in conformance with Ada County Highway District's Drawing No. 320. The manhole invert shall provide a smooth flow-through characteristic. No sharp edges or rough sections which will tend to obstruct the flow_of sewage will be permitted. Where a full section of sewer pipe is laid through the manhole, the top shall be broken and the exposed edge of the pipe .shall be completely covered with mortar. All cement mortar used in the construction of the invert shall be troweled smooth. -8- d. Manhole Rings and Covers The cast iron manhole rings and covers shall be installed on the top of the manholes so as to positively prevent any infiltration of surface or groundwater into the manholes. The manhole rings shall be set so the tops of the covers are just flush with the surface of the adjoining pavement_or ground surface unless otherwise shown on the Plans or directed by the Engineer. -9- E13 212 Tenth Avenue South -U-B ENGINE RS, INC.

SHARP Chairman Zoning & Planning The City of Meridian, Ada County, Idaho Ordinance Section 7-517 states: Required use of sewers: The owner or occupant of any house, building or property used for residential, commercial, industrial, governmental or recreational use, or other purpose, situated within the City which is abutting on or having a permanent right of access to any street, alley or right of way in which there is located a public sewer of said City is hereby required to cease using any other method of disposing of sewage, waste or polluted water, and at his expense to connect such building directly with the public sewer in accordance with the provisions of this Chapter, within fifteen (15) days after date of official notice from the City to do so, provided, however, that said sewer is within three hundred feet (300') of any property line of the building to be served or common property line in a multiple building development. The developer of a new subdivision shall, at his expense, construct the necessary extensions of the public sewer system to provide public sewer facilities for each lot in his subdivision. It shall be unlawful for any person to place or deposit in any unsanitary manner on public or private property within the City, or in any area under the jurisdiction of said City, any human or animal excrement, garbage or other objectionable waste. It shall be unlawful to discharge to any natural outlet within the City, or in any area under the jurisdiction of said City, any sewege or other pol- luted waters, except where suitable treatment has been provided in accor- dance with subsequent provisions of this Chapter. Except as hereinafter provided, it shall be unlawful to construct or main- tain any privy, privy vault, septic tank, cesspool or other facilities intended or used for the disposal of sewage.

WILLIAMS GRANT P. KINGSFORD BILL BREWER RICHARD F. ORTON, JR. DONALD L. SHARP Chairman Zoning & Planning Today I received a letter from Mr. Jack Dowdle, of Gem Estates, Inc., regarding the subject subdivision. The last paragraph states that if I have further questions to direct them to you. Mr. Dowdle states in the second paragraph that "the buildings have now been constructed on all of the lots so it would be impossible to increase the easement width to sixteen feet as requested". The Meridian City Council, during their meeting of March 3, 1980, required that record drawings of the subdivision and improvements be prepared by Mr. Dowdle and submitted to the City as a condition for final plat approval. At the City Council meeting of May 5, 1980, I asked if Mr. Dowdle had been so informed of the March 3 meeting requirements, and was told that he had not. I then requested that the City Attorney, Mr. Wayne Crookston, so inform Mr. Dowdle of the Council's actions which he said he would do. Until a physical location of the buildings adjacent to the subject sanitary sewer line proves non -compatibility with a wider sanitary sewer easement, the requirement for the additional width of easement remains.

WILLIAMS GRANT P. KINGSFORD BILL BREWER RICHARD F.ORTON, JR. DONALD L. SHARP Chairman Zoning 6 Planning JOSEPH L. GLAISYER Mayor MEMORANDUM TO: Honorable Mayor and City Council FROM: Gary D. Smith, P.E., City Engineer DATE: October 9, 1980 RE: GEM ESTATES '84SDIVISION, SANITARY SEWER SYSTEM As a result of our rt meeting at the site during the evening of October 6, to observe the status of the referenced sewer system, I offer for your consideration the following comments. 1. 8 Inch Diameter Lateral D-1. (The northerly most east -west line). Physically there appears to be adequate room between the buildings if in the future it was necessary to bring in equipment to make any repairs to the lateral. My previous request for a 16 foot wide easement could effectively be reduced to 15 feet. I say this for convenience purposes, since the plat presently has a 10 foot wide easement on the south side of the Northerly lots adjoining this lateral and the City Subdivision Ordinance requires a 5 foot wide sideyard set back which would be designated as "sanitary sewer easement" on the North side of the Southerly adjoining lots. This combination results in the 15 foot wide easement which would be adequate. 2. 8 Inch Diameter Lateral B. (Southerly most east -west lateral.) This lateral is located in an asphalt paved access driveway between apartment buildings. The plat presently shows a 15 foot wide easement for this lateral and its location provides sufficient clearance for possible repair equipment access. 3. 18 Inch Diameter Trunk Line. The location of a portion of the North-South trunk line is within 2-3 feet of the westerly side of one of the apartment buildings. The location does, however, seem to be in accordance with the development plans that were apparently approved by the City at some point of time in the past. The width of the easement for this trunk is shown as 16 feet on the plat and does conform with my earlier request to Mr. Dowdle. 4. 18 Inch Diameter Trunk Line Construction. It is necessary that the developer complete the construction of the trunk line as shown on his Engineer's "Ultimate Sewer Plan -Profile" drawing. The work items yet to be done include: Honorable Mayor and City Council -2- October 9, 1980 a. Connect the new 18" diameter trunk line and plug the existing 18" diameter trunk line at the manhole in West Broadway Avenue at the Southeast corner of the development. b. Connect the new 18" diameter trunk line and plug the existing 18" diameter trunk line at the trunk line manhole located 101.6 feet south of the trunk line manhole in West Idaho Avenue. C. Plug the existing trunk line inlet and outlet at the manhole in West Seventh Street that is located over the 8" diameter lateral identified as "Line B" on the engineering drawings. It will also be necessary to construct a channel through this manhole to promote the transition of flow from the East part of the lateral to the West part. An existing service line from the living units to the South and West of this manhole enters the west side of the manhole on an alignment parallel to the alignment of lateral "B". Presently solids and paper are building up on the manhole shelf. The developer must either remodel the transition of this line into the manhole to eliminate the solids and paper buildup or remove the service therefrom and connect the two affected apartment units to Lateral "B" with standard service taps. If you have any questions, please don't hesitate to call. If you find my comments and recommendations to be in order with the existing situation, I would recommend that the developer be so advised by letter.
