Civil Engineering * Project Management DATE: March 20, 2019 TO: City of Meridian 33 E. Broadway Ave Meridian, ID 83642 RE: Warrick Subdivision #1 To whom it may concern: Based on a geotechnical report and experience with various projects in this immediate area, groundwater is at least 5 feet below existing ground elevation. All streets have been designed so that the centerline of the street is at least 3 feet above seasonal groundwater. Respectfully submitted, Chad S. Kinkela, P.E. CK Engineering, P.C.

Box 1115 Meridian, ID 83680 (208)-880-1695 CK Engineering 1300 E. State St Suite 102 Eagle, ID 83616 208.869.0590 mobile chad@cic-engineers.com Wells Subdivision is a 50 lot single family residential subdivision. Within this subdivision there will be 42 single family residential lots and 8 common lots. The project is bound on the north side by Amity Road, on the east side by the Ten Mile Drain, and on the West side by a single family residential Subdivision. On August 8, 2018, MTI excavated test pits on this site. Please see the attached report prepared by MTI. Seasonal high groundwater was observed at approximately 5-8 feet below existing ground, varying a crossed the site. Please note that we are in the process of gaining an additional geotechnical report from Bob Arnold of Site Consulting for test pits at the exact location of each seepage bed. The second Geotechnical Report is also to confirm the percolation rates onsite as we disagree with what the original geotechnical report states. There are two storm drain seepage trenches on this site. The storm drain system was sized using ACHD's storm drain spread sheet and the two seepage trenches (Seepage Bed i and Seepage Bed 2) were designed per ACRD BMP 20. Seepage Bed #1 is 35'W x 3'D x 201'L. Seepage Bed #1 is located within a common lot and takes drainage from drainage areas #1-#6. Seepage Bed #2 is 30'W x 3'D x 76'L. Seepage Bed #2 is located within a common lot and takes drainage from drainage areas #1-#6. Each seepage bed takes water from catch basins which are directed towards catch manholes before discharging into the seepage bed. Each bed is designed to be 3 ft above seasonal high groundwater. Please see attached ACHD spreadsheets and groundwater monitoring report. There are two barrow ditches being added in to the frontage along existing Amity Road. Barrow ditch 1 is REQUIRED to hold a storm drain volume Of 803 CF from drainage area #9. Barrow ditch 2 is REQUIRED to hold a storm drain volume of woo CF from drainage area #10. The barrow ditches have a 4:1 side slopes and are 13 ft wide. This allows the barrow ditches to be 1.375 ft deep and have a storage capacity of 10.31 CF per LF of barrow ditch. Barrow ditch 1 is 189 ft long and barrow ditch 2 is 193 ft long. This gives a DESIGN volume for barrow ditch I of 1948 CF and a DESIGN volume of barrow ditch #2 of 1989 CF. Each barrow ditch has ample storage for the 100 year storm. The barrow ditches are directed towards continuous sand windows with an infiltration rate of 8"/hr. This allows the barrow ditch to drain without ponding occurring. Continuous sand windows are used based on existing Amity Road slopes. Attached is the ACHD spreadsheet showing the storm drain calculations and the MTI geotechnical report. CK Engineering 130o E.
