Water Environment - 62-345.500(6)(b), FAC Scoring Guidance The scoring of each indicator is based on what would be suitable for the type of wetland or surface water assessed w/o pres or current w/o pres or current w/o pres or current PART II – Quantification of Assessment Area (impact or mitigation) (See Sections 62-345.500 and .600, F.A.C.) Site/Project Name Application Number Assessment Area Name or Number Impact or Mitigation .500(6)(a) Location and Landscape Support with .500(6)(b)Water Environment (n/a for uplands) with .500(6)(c)Community structure 1. Vegetation and/or 2. Benthic Community with Optimal (10) Condition is optimal and fully supports wetland/surface water functions Assessment conducted by: Moderate(7) Minimal (4) Condition is less than optimal, but sufficient to maintain most wetland/surface waterfunctions Assessment date: Minimal level of support of wetland/surface water functions Twelve attributes are considered to generate the score for Water Environment Not Present (0) Condition is insufficient to provide wetland/surface water functions Twelve attributes are identified in the UMAM Rule to evaluate this category. To provide guidance, examples that depict variation in conditions for each of the attributes are included. • Water levels and flows • Water level indicators • Soil moisture • Soil erosion or deposition • Evidence of fire history • Vegetation - community zonation • Vegetation – hydrologic stress • Use by animal species with specific hydrological requirements • Plant community composition – species tolerant of and associated with water quality degradation or flow alteration • Direct observation of standing water • Existing water quality data • Water depth, wave energy, currents and light penetration Score = sum of above scores/30 (if uplands, divide by 20) current or w/o pres Delta = [with-current] with If preservation as mitigation, Preservation adjustment factor = Adjusted mitigation delta = If mitigation Time lag (t-factor) = For impact assessment areas FL = delta x acres = For mitigation assessment areas Be aware that not all attributes are applicable to all assessment areas and in some cases, some attributes may be more relevant than others. Risk factor = RFG = delta/(t-factor x risk) = Form 62-345.900(2), F.A.C. [effective date 02-04-2004]
Water Environment - 62-345.500(6)(b), FAC Scoring Guidance The scoring of each indicator is based on what would be suitable for the type of wetland or surface water assessed PART II – Quantification of Assessment Area (impact or mitigation) (See Sections 62-345.500 and .600, F.A.C.) Site/Project Name Application Number Assessment Area Name or Number Impact or Mitigation Optimal (10) Condition is optimal and fully supports wetland/surface water functions Assessment conducted by: Moderate(7) Minimal (4) Condition is less than optimal, but sufficient to maintain most wetland/surface waterfunctions Assessment date: Minimal level of support of wetland/surface water functions Not Present (0) Condition is insufficient to provide wetland/surface water functions The final score for the Water Environment category is a reflection of the overall condition of an assessment area, taking into consideration all applicable attributes (do not score each attribute and average them in the end, but rather think of this in terms of what final score best fits the overall conditions of the assessment area). Any whole number score between 0-10 may be used. w/o pres or current w/o pres or current w/o pres or current current or w/o pres .500(6)(a) Location and Landscape Support Delta = [with-current] with .500(6)(b)Water Environment (n/a for uplands) with .500(6)(c)Community structure 1.

Benthic Community with Score = sum of above scores/30 (if uplands, divide by 20) with If preservation as mitigation, Preservation adjustment factor = Adjusted mitigation delta = If mitigation Time lag (t-factor) = For impact assessment areas FL = delta x acres = For mitigation assessment areas The rule lists descriptors of attributes for 4 categories of scores as guidance: •A score of (10) means that the hydrology and water quality fully supports the functions and provides benefits to fish and wildlife at optimal capacity for the assessment area. •A score of (7) means that the hydrology and water quality supports the functions and provides benefits to fish and wildlife at 70% of the optimal capacity for the assessment area. •A score of (4) means that the hydrology and water quality supports the functions and provides benefits to fish and wildlife at 40% of the optimal capacity for the assessment area. •A score of (0) means that the hydrology and water quality does not support the functions and provides no benefits to fish and wildlife. A Summary Worksheet for the Water Environment is included to help in the field assessment scoring. Risk factor = RFG = delta/(t-factor x risk) = Form 62-345.900(2), F.A.C. [effective date 02-04-2004]
