Bragaw Street P. O. Box 196650 Anchorage, Alaska 99519 Subject: Lot 4 Campbell Canyon S/D Septic System Permit Request Ladies and Gentlemen: I am writing to request a permit to construct a new septic system be issued for this property. The proposed systems will serve a new three-bedroom house. Currently the lot is undeveloped. The lot is served by a community water supply. Both primary and reserve septic system shall be installed under this permit. A diverter valve will be installed between the new tank and the new fields. The surrounding developed lots are served by the same community water system. 1. Soils. Two test holes were excavated. The soils logs and percolation tests are on file with your office. No ground water was monitored to a depth of 18 feet below ground level after the monitoring period. Bedrock was not encountered in the test holes. It is my opinion, based on the results of the percolation tests and overall soils appearance; an application rate of 1.2 gallons/day/square feet should be used, using a conventional treatment system. 2. Soil Absorption System Design. a. Percolation Rate: b. Application Rate: c. • Design Flow: d. Min. Absorption Area: e. Total Depth: f. Effective Depth: g. Width: h. Reduction Factor: i. Minimum Length: j. Design Length: k. Effective Absorption Area: 1. Septic Tank Size: 1 to 5 Min Per Inch 1.2 gpd/sf 450 gallons per day 375 sf 9 feet 5.0 feet 2.0-3.0 feet 0.0 37.5 feet 38 feet 380 sf 1,000 gallon 3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and the existing drain field. The proposed drain field upgrade will maintain at least 100 feet from all surface water and drainage ditches. 4. Topography: The average topography in the area of the proposed septic system is approximately 2 percent based on the survey information. The proposed installation will be greater than 50 feet from the shoulder of the steep slopes. Page 2 of 2 5. Drawing Markings: The Drawings are marked "For MoA Review Only". When written notification that the review is complete and that there are no further comments is received from MoA On -Site Department, the note will be removed and "Released for Construction" drawings will be issued. The proposed installation will not affect the future development of the surrounding or existing lots. There are no wells within 200 feet of the proposed septic location or septic systems within 20 feet of the proposed septic location. If you have any questions or concerns, please contact me at 272-8218 Sincerely, Steven R. Pannone, P.E.

Specifically: • Solid pipes transporting wastewater from the house to the septic tank, and from the septic tank to the drain field shall have a minimum of 36 inches of vertical separation between any storm drain or footing drain. If 36 inches of separation cannot be Page 4 of 8 2/21/2007 maintained, install a minimum four -inch (4 -inch) thick insulation buffer between the septic system and the storm drain or footing drain. • Solid pipes transporting wastewater from the house to the septic tank, and from the septic tank to the drain field shall have a minimum of 11 feet horizontal and 18 inches vertical separation between water service lines and mains. Sanitary sewer pipes shall be centered over the crossing and no joint shall be closer than at least half the standard pipe length to the waterline crossing. Septic Tanks and Drain Fields shall be placed no closer than: • 100 feet to any private well, unless previously approved by the MoA; • 11 feet horizontally measured to any water main, water service, storm sewer, street light, transformer pad, electrical/telephone/cable box; • 10 feet horizontally measured to any side lot line • 50 feet up -gradient or 20 feet down -gradient of any footing drain or curtain drain. • Those separation distances required under AMC 15.65 The Contractor shall relocate any item installed with less than minimum measured distances prior to final inspection and at no cost to the Owner. 3.02 LOCATIONS AND GRADES. The Contractor shall verify and record the horizontal and vertical locations of all utilities encountered in the field and record any changes on the Contractor Record Drawings. The Contractor shall hire or employ a Registered Land Surveyor to stake the location of the septic tank, drain fields, property lines, well, 100' well radius, ten -foot property line setbacks, or any other required feature. Failure to properly stake these locations shall be at the risk of the Contractor and the Contractor shall be responsible if the required distances are not met. The septic tank shall be placed at the locations and elevations as shown on the Drawings. The tank shall be set levet to a tolerance of plus or minus 0.05 feet from end to end. The drain field shall be placed in the location shown on the Drawing, with minor adjustments allowed to minimize excavation and accommodate the existing terrain. The drain field piping shall remain level over the length of the drain field. The drain field shall be constructed entirely within 30 feet of the test holes shown on the Drawings. Contact the Engineer immediately if the drain field cannot be installed in the location shown on the Drawings. 3.03 EXCAVATION. Sewer services pipes shall be bedded. Bedding and trench backfill shall be compacted to 95% of maximum density. Material that is placed while frozen or during freezing conditions shall be removed and replaced during periods when the material is thawed so proper compaction can be achieved. Page 5 of 8 2/21/2007 3.04 SEPTIC TANK. The septic tank shall be placed on undisturbed soil on a level grade at a depth as indicated on Drawings. Backfill around the tank with sewer gravel fill to at least the spring line of the tank. Fill above the spring -line of the tank shall be installed in 12 -inch lifts compacted to 95% maximum density. Any damage to the protective coating during installation shall be repaired as recommended by the manufacturer. The tank inlet shall be set at the elevation shown on the Drawings. Care shall be taken during installation to ensure the proper elevation drop between the inlet and the outlet. Install flexible "Fumco" rubber fittings, or approved equal, at connection from tank to inlet and outlet pipes as indicated on the Drawings. The Contractor shall take caution to prevent the tank from floating once it is set in place. The Contractor shall reset the tank to the proper grade if it floats, at no additional cost to the Owner. 3.05 PIPES.
