Addendum to "Lack's I oik sUrnmaty infoi Illation
1 Site specific Monitotirng Issues This stream iestotation site is situated with a municipal soccer
paik directly abutting on the noith side and a sewei easement along much of the south side Yeaily
monitoring was complicated by issues arrsmg floor thud -patty landscape maintenance and easement
maintenance, on multiple occasions, stakes designating monitoring locations from the As Built
documentation were displaced of missing entirely in subsequent years Where possible, ESI attempted to
reestablish monitoiing stations by using non pins placed below the soil surface to facilitate relocation in
subsequent years using a hand held magnetometer
2 Graphical Depictions The Longitudinal Ptofiles have been scaled horizontally by aligning the
locations of majoi grade control stluctutes with the As -Built survey This presentation allows evaluation
of the development of riffle pool sequences and propoitionally distributes any error in field measurement
across the entire reach All fifty Cross Section Profiles have been standardized so bankfull (BKr)
elevation Is based on the drainage basin and is thus unrfolIll from year to yeai This standardization was
also checked and conf imed against the design parameters Field collection of BKF elevation was
inconsistent, in part because many cross sections span lock stluctutes where not mal BKF indicators (e g
depositional benches, moss trim lines, water staining) are subtle of absent
3 Tabular Data Sonle calculations for Cioss Sectional Atea (CSA) and Flood Prone Length
(FPL) mete initially done incoirectly The standardized BKF values (described above) was used to
replace the eiiatic field measurements and CSA values then recalculated As regards FPL, some of these
were initially calculated using cross sectional widths instead of flood prone width These values have
been ie calculated and cotrectly tecoided in the amended SUmmaty Table
