3 resources. The responsibility for the management of shoreland areas is hereby recognized by the city. Section 1102.03 Definitions. SHORELAND. Land located within 1,000 feet from the ordinary high water level of the lakes and land located within 300 feet from the streams classified in § 1102.05 or the landward extent of a flood plain designated by ordinance on a river or stream, whichever is greater. The limits of shorelands may be reduced whenever the waters involved are bounded by topographic divides which extend landward from the waters for lesser distances and when approved by the Commissioner. Section 1102.07(1)(c)4. Impervious surface coverage of lots must not exceed the following percentages of lot area: NE RD GD R Single-family 30% 30% 30% 30% Two-family/duplex 30% 30% 30% 30% Triplex/quad/townhomes 35% 35% 35% 35% Commercial/industrial 60% 60% 60% 60% The subject site, 6650 Enid Trail, is a single-family lot located within the shoreland overlay of Rice Lake which is classified as a Natural Environment (NE) lake. Therefore, the maximum allowed impervious surface is 30%. It should be noted that even if this lot were not in the shoreland overlay district, the standard R-1 allowed impervious surface coverage is only 40%. The proposed house plan with 43.7% impervious would not meet either of these minimum requirements. As explained in the MNDNR Shoreland & Floodplain Variance Guidance handout (Attachment #6), in the protection of water quality, the management of rainwater on individual lots is one of our most important tasks. As impervious surface coverage increases, the rate and amount of runoff and pollutants entering the public waters increases. The handout also details “Considerations for Findings”, “Range of Outcomes” and “Conditions on Variances”. Applicant’s Narrative See Attachment #3 for the Applicant’s Narrative. The following summarizes the applicant’s variance arguments followed by City’s response in italics. 1. The lot is irregular with an atypically long driveway. The lot is a standard 80’ wide x 135’ deep R-1 lot. The applicant chose to “flip” the house and relocate the driveway to the north causing it to be longer and larger. 2. The applicant proposes a rain garden/infiltration basin in the rear yard, gutter and downspouts and side yard swale. Reasonable conditions such as rain gardens, porous pavers or downspouts could be required only if all variance criteria are met. As detailed below, these variance criteria are not met.
