flco-i zone is an intermittent branch of the Rush River. A floodplain analysis was prepared by Matt
A: pel. P.L., of Advanced engineering Concepts to investigate the impact of the proposed dnvevay
,n the Regional Flood Flevation (RFE). This analysis was reviewed by the Department of Natural
Ib: sources and the analysis was found sufficient, therefore conditionally approving the study as
complying with Wisconsin Administrative Code NR 116. Since the Unnamed Tributary is Currently
-napped as Zone A floodplain, an increase of less than 1-foot is allowed as long as a flood easement
o, other appropriate legal arrangement is secured from all adversely affected property owner,, in
c:_,r, Rance with Section 17.40 1.8.4. of the St Croix County Floodplain Zoning Ordinance. On March
26, 2019, an easement was recorded describing the flooding easement between the property owner
,ason Biqnell; and the affected property owner (M. Croix County Highway Department); the
•eccrdinq document number is 1079364.
C March Z/. 2019. the State Sanitary Permit was issued (60704). the building site as proposed in
'he site plan for this permit is swell outside of the lone A floodplain area.
Based on these findings, approval of the Land Use Permit is subject to the following conditions:
1. Future structure or a residence must have any low opening at minimurn of 2-feet above the RFE
alonq the floodway within this property The minimum low opening at the highest point on the
oroperty is 116*1.65'. See Table. 6 (page 5) of the I W I study for corresponding river station along the

Subject: Unnamed Tributary to the Rush River Hoodplain Determination, Town of Pleasant Valley, St.
Croix County, Wisconsin - Floodplain Analysis Conditional Approval
Dear Ms. Borrell,
I he Department of Natural Resources has reviewed the floodplain analysis prepared by Matt Appel, P F ,
of Advanced Engineering Concepts, to investigate the impact the proposed driveway has on the Regional Flood
Elevation (RFF) for an Unnamed Tributary to the Rush River. I he analysis was completed on behalf of Mr- Faison
Bignell, located in Section 16, Township 28 North, Range 1/ West, Town of Pleasant Valley, St. Croix County,
Wisconsin.
The analysis Utilized various method; to calculate the regional flood discharge associated with the Unnamed
Tributary to the Rush River. I hose methods included the 2003 USGS Flood frequency Regression I quations, TR-
SS, Basin Comparison and the Rational Method. As a result of the I R-55 hydrologic analysis, a regional flood
discharge of 177 cfs was used for the analysis.
[he study implemented HEC-RAS 4. 1.0 to establish the Regional Flood Llevation (RFE) for each corresponding
river station. Based on the assumptions applied by Advanced Lngineering Concepts, the RFF for each river
station is presented in the final floodway data table in the report. The proposed driveway is located is between
RS 642 and RS 575. According to the analysis the driveway does cause increases of approximately 0.94 ft.
immediately upstream at RS 642, and 0.12 ft. immediately downstream at RS 515.
1 he final floodplain analysis and report titled "Determination of the Regional Flood Elevation -Jason Bignell
Property" was submitted to the Department on January 16, 2019. The Department will consider the
assumptions applied in the analysis sufficient, therefore conditionally approving the study as cornplying with
Wisconsin Administrative Code NR 116 technical standards for application of St. Croix County's Floodplain
Zoning Ordinance. Since the Unnamed Tributary is currently mapped as a Zone A floodplain, an increase of less
than 1 ft. is allowed as long as the flood easements or other appropriate legal arrangements are secured from all
adversely affected property owners in compliance with 17.40(1)(8)(4) of St. Croix County's Floodplain Zoning
Ordinance.
