During these on- sites,bofings were excavated to confirm soil conditions where two conflicting soil reports had been submitted for zog 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 SchumakerGOVeak,: 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, "I 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 yM li t 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 l 4A s ,}. ,.1 .or,-`2. be assi -a lawer, � _�3t, - see attached memo Vfh t tl Meadows)to provide a larger dispersal area. ( I r Page Two—Soil Memo 4/27/04 Massive sandy foams have been assigned a soil application rate of-0.2 gpd/fe with the code Ranges in Comm J tine as of 2/1/04. The application rates listed go the.soil reports were higher due tot structure having boon described A-'ether weak or moderate;Kieft 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 desc ri bed o n 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"1 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.
