El Bird Plumbing Inc. 1008 192nd Ave New Richmond WI 54017 715-246-4516 Subject: Whitetail Meadows Soil Tests To Whom it may concern: I Shaun Bird did the soil tests on this subdivision known as Whitetail Meadows in Richmond township. Aftbr a couple of installations, some of the soils were found to have a more weak structure than what was found in some of the borings. In order to protect home owners and contractors, it is my recommendation after discussing the issue with Pam Quinn from St. Croix County Zoning office that the systems be oversized using a.3 loading rate instead of the original .4 rate. On the lots that were originally sized for a.5, I recommend using a.4, not the new.6 that the state has suggested. The soils are what the tests indicate but the large areas tested did not reveal some of the weaker structures that were found upon installations. If a installer can prove otherwise, that the weaker structures do not exist, then the installer should proceed with the soils that he/she believes are present.

During these on- sites, borings were excavated to confirm soil conditions where two conflicting soil reports had been submitted for zoning department review. The soil profiles, evaluated by myself, Dave Fogerty, and Dave Steel (all certified soil testers) differed from the original soil reports in that massive (structureless) sandy loams were encountered in horizons that were described as having either moderate, medium subangular blocky (2msbk) structure by Adam Schumaker or weak, medium granular structure (Imgr) by Shaun Bird. There apparently has been a misunderstanding between "structure" caused by handling samples of the soil during texturing versus the soil characteristics in situ. The soil, when chunks were taken out of the profile to hand texture, with pressure parted into "crumbs" that appeared at first to be subangular or granular in shape. However, these were not true peds that broke apart along planes of weakness, but fragments created by handling. The soil when observed in the horizon did not have distinct units of structure and should have been reported as "massive". Added notation: on 4/23/04 Mark Iverson (Cedar Corp. certified professional soil scientist), Shaun Bird, and myself did an evaluation of soils on Lots 6 & 9, Richmond Meadows where the original soil report described the third horizon as sandy loam, "1 mgr". On Lot 6 we checked soil profiles within a POWTS distribution cell and then excavated a test pit on Lot 9. The sandy loams in question were a weak, coarse to very coarse subangular blocky structure, where planes of weakness were just discernible when peds were parted from the profile. The peds separated with very light pressure by soil tester. Sand coatings were observed on the ped faces in the Lot 9 soils, which supported the determination that some structure existed to allow water to move through the upper portion of the sandy loam horizon. However, below the weak-structured soil we found massive (structureless) sandy loams and the boundary between these horizons was irregular, which would mean a distribution cell could encounter alternating weak and massive sandy loam. Shaun said he would amend his soil reports with a memo recommending that any sandy loams he identified as "lmgr" or "2 mgr" be assigned a lower loading rate of 0.3 gpd/ft2 (see attached memo for Whitetail Meadows) to provide a larger dispersal area. Page Two - Soil Memo 4/27/04 Massive sandy loams have been assigned a soil application rate of 0.2 gpd/ft2 with the code changes in Comm 83.44-2, effective as of 2/1/04. The application rates listed on the soil reports were higher due to the structure having been described as either weak or moderate, which affects the calculations for sizing of POWTS distribution cells. Obviously, one of the concerns is to make sure loading rates for the soils are not in error and allow undersized POWTS to be installed. For example, in December 2003, Lot 35 of Richmond Meadows subdivision had to have its loading rate reduced to 0.3 gpd/sq. ft. when the installer encountered massive sandy loam at the system elevation. The sandy loam horizon had been described on the soil report as "1 mgr" with firm consistence. Leroy Jansky, Dept. of Commerce Regional Wastewater Specialist, has been consulted on this situation and advised the zoning department to require on-site verifications for any lots with this potential misinterpretation on the soil reports. All soil reports with sandy loam "l or 2 mgr" as its structure will be required to use a design based on the current code's soil application rate for massive sandy loam @ 0.2 gpd/sq. ft. unless additional soil testing proves otherwise.
