INTRODUCTION Wetland Replacement monitoring is required for up to five [5] years following the completion of a wetland replacement project to determine if the replacement wetland achieves the goal of mitigating functions and values lost due to project impacts. The replacement wetland should meet both the general and specific requirements as outlined in Section 8420.0550 Subpart 1. of the 2002 Wetland Conservation Act Rules (Appendix A). This report presents observation for the 2009-monitoring year for the Hunters Pass Development in Albertville, Minnesota. The Hunters Pass development was located in the NE'/ of Section 36, Township 121N, Range 24W, City of Albertville, Wright County, Minnesota (Figure 1). More specifically, the Hunters Pass development is located southwest of the intersection of 701h Street NE and Maciver Avenue NE. The 2009 monitoring site visit took place on November 6th. At that time vegetation was actively senescing, temperatures were in the 60's, and hydrology was assumed to be normal due to generally above average precipitation during the months preceding the site visit (Appendix B). II. PROJECT SUMMARY A total of 1.81 acres (78,844 square feet (sf)) of Type 1 and 3 wetlands were impacted as part of the Hunters Pass Development. Required replacement was at a 2:1 ratio for a total of 3.62 acres (157,687 sf) of replacement, half of which must be New Wetland Credit (NWC). Seven Replacement Wetlands totaling 2.51 acres (109,118 sf) of NWC were approved for _ creation while only 1.81 acres (78,884 sf) of NWC were required for project specific replacement (Figures 2, 2A, and 2B). Extra NWC was created to ensure enough NWC was established for project replacement even if new wetlands were smaller than predicted. Public Value Credit (PVC) replacement was to be derived from a combination of upland buffer adjacent to the new wetlands, preserved buffer areas, and stormwater treatment ponds (Figure 3). Buffer averaging 30-feet in width was to be established adjacent to all Replacement Wetlands and existing wetlands and was to be seeded with a native mesic prairie seed mix. Four areas of existing woodland totaling 51,886 sf were to be preserved. Areas that were utilized as PVC replacement consisted of one preserved buffer area of 17,538 sf adjacent to RA 5, 80,810 sf of native seeded buffer, and five stormwater treatment ponds totaling 82,777 sf. III. MONITORING BACKGROUND/ SITE HISTORY 2009 represents the fourth (4"') year the replacement wetlands on the Hunters Pass development were monitored. The City of Albertville granted approval for the Wetland Replacement Plan in May 2005 (Permit No. 2005-001) and the Army Corps of Engineers granted approval on April 21 ", 2005 (Permit # 04-161467-TJF) (Appendix Q. Construction of the replacement wetlands (with the exception of Replacement Area 3) was completed by the end of 2005, and seeding of all replacement wetlands was done in May of 2006 by Prairie Restorations, Inc. (PRI). Mowing and spot herbicide applications for maintenance purposes occurred during the 2006, 2007, and 2008 growing seasons. RA 3 was constructed prior to the 2007 monitoring season. According to the original developer (Minnesota Development Agency), the Declaration of Restrictions and Covenants over the replacement wetlands and buffer have been recorded. In 2006 buffer signs were installed adjacent to Replacement Areas 5 and 6. The location of .— future buffer signs were staked with wood lath adjacent to Replacement Areas 1, 2, 3 and 4 as they were (and are still) undeveloped lots. No signs were planned adjacent to Replacement Area 7 as this area is not located adjacent to future home sites. The boundaries of all replacement areas (except for RA 3) were located with a Leica GPS unit (with submeter accuracy) at the time of the 2006 monitoring site visit. The boundary was subsequently overlaid onto the approved wetland replacement plan to determine the actual amount of new wetland credit established on the site (Figures 4 to 4C). The survey shows the location of the original wetland delineation, the new wetland boundary (as delineated and located with GPS in the field by KES, and labeled as -built field data on Figures 4A to 4D), with actual NWC shown in cross hatching. For several of the replacement wetlands, the grading plan included some minor scraping into adjacent existing wetlands to construct a smooth transition between the new and original edge which explains why the GPS-located boundary (as -built data) is shown within the existing wetland in many cases. Only new _ wetland areas outside of the original wetland were counted as NWC. Details of the survey will be discussed in the results section. The boundaries of RA 3 and RA 7 were delineated in the field and subsequently located with a Leica GPS unit (with submeter accuracy) in spring 2009. These wetland boundaries are shown on Figure 4 and their sizes were estimated by Arcview. Vegetation management activities conducted by Prairie Restorations in 2009 are provided in Appendix D and included a number of herbicide applications as well as mowing. IV. METHODS Vegetation and hydrology were documented at fixed photo reference points as shown on Figures 5, 7, 9, 11, 13, 15, and 17. Plant species dominance was estimated based on a meander survey throughout the new wetland area. The location, composition, and extent of plant communities was described for each replacement area. Hydrology characterizations consisted of aerial coverage estimates during the site visit. Photographs were taken at one to three fixed photo points at each replacement wetland and were referenced to fixed points identified on the wetland replacement plan and labeled accordingly. V. RESULTS Replacement Area 1 (RA 1) (Figures 5 and 6) A total of 6,184 sf of NWC was to be created adjacent to existing wetland by excavating to elevations ranging from 947.0 to 948.0 msl to create saturated and emergent wetland that blended with the original wetland edge. Hydrology was to be supplied by groundwater and shared hydrology from the adjacent wetland. Based on the delineation, a total of 5,987 sf of new wetland was created in RA 1 (Figure 4A). At the time of the November, 2009 site visit over 75 percent of the basin was inundated with at least a few inches of water and the remainder was saturated. RA 1 was well vegetated and the plant community consisted of many dominant natives such as spike rush, common plantain, and barnyard grass. Reed canary grass is present, but abundance appears to be below 50%. Details of the observed plant community are included in Figure 5. Buffer Description A total of 15,246 sf of buffer was proposed adjacent to the west edge of Replacement Area 1. The buffer composition was very similar to that observed during the 2008 monitoring season. The plant community is described in Table 1 below. 1 13A1B ff r Table . u e Species % Cover Species %Cover Schizach rium sco arium 15 Echinacea purpurea Trace El mus canadensis 15 Verbascum tha sus Trace Andro 0 on gerardii 15 Melilotus alba Trace Ratibida pinnata 15 Phalaris arundinacea Trace Bouteloua curti endula 15 Trifolium s .

Hydrology was to be supplied by groundwater and shared hydrology from the adjacent wetland. Based on the 2006 GPS delineation, a total of 2,625 sf of NWC was established in RA 2 (Figure 413). At the time of the site visit, approximately 75 percent of the basin was inundated with one-half to a few inches of water and the remainder was saturated. RA 2 was dominated by spikerush and fowl bluegrass. Details of the plant community are described in Figure 7. Buffer Description A total of 27,878 sf of buffer was proposed adjacent to the west and north edge of the new wetland and was to extend east along existing wetland. Since most of this buffer area extends well east of the replacement wetland, only one-third (9,148 sf) of the total area will be calculated as PVC. Buffer adjacent to the north side of RA 2 was consistent with the plant community _ described in Table 1. As in 2008, buffer further east of RA 2 was slightly different in that white panicled aster, fringed brome, and Canada bluegrass represented more cover than the community described in Table 1. Replacement Area 3 (RA3) (Figures 9 and 10) A total of 4,356 sf of NWC was to be created adjacent to existing wetland by excavating to _ elevations ranging from 950.0 to 951.0 msl to create saturated and emergent wetland that blended with the original wetland edge. Hydrology was to be supplied surface runoff and shared hydrology from the adjacent wetland. Based on the 2009 GPS delineation, a total of 3,777 sf of NWC was established in RA 3 (Figure 4). At the time of the site visit, RA 3 was dry throughout and was dominated by reed canary grass. Details of the plant community are described in Figure 9. Based on past hydrology observations, as well as 2009 hydrology observations it is possible that the majority of RA 3 is not wetland. Buffer Description A total of 6,970 sf of PVC buffer was to be established adjacent to Replacement Area 3. Although the soil stockpile observed in 2008 had been removed, at the time of the 2009 site visit the buffer areas adjacent to the northeast part of RA 3 still appeared to be disturbed and included species such as mare's tail, clover, sweet clover and annual ragweed. Otherwise buffer generally consisted of the same plant community as last season as described in Table 2 below. 4 Table 2.

Hydrology was to be supplied by groundwater and shared hydrology from the adjacent wetland. Based on the 2009 GPS delineation, a total of 6,641 sf of NWC was established in RA 4 (Figure 4B). At the time of the November, 2009 site visit over 75 percent of the basin was inundated with at least a few inches of water and the remainder was saturated. RA 4 was well vegetated and the plant community consisted on many dominant natives such as fowl bluegrass, spike rush, cattail, and native Aster sp. (Symphyotrichum sp.). Details of the observed plant community are included in Figure 11. Buffer Description A total of 11,326 sf of buffer was proposed to surround the new wetland (with the exception of the south edge) and was to extend east along existing wetland. Buffer adjacent to RA 4 was similar to that observed in 2008 as described in Table 3. Buffer further east of RA 4 was similar except that wild bergamot made up 10 percent cover and gray -headed coneflower represented 30 percent. Table 3.

Hydrology was to be supplied by groundwater and shared hydrology from the adjacent wetland. Based on the delineation a total of 3,915 sf of NWC was established in RA 5 (Figure 4B). At the time of the site visit 100 percent of RA 5 was inundated with 1 to 2 inches of water. -' The plant community was dominated by fowl bluegrass and included numerous native non -dominants. Details of the plant community are included in Figure 13. Buffer Description A total of 17,538 sf of preserved buffer was originally proposed along the east edge of Replacement Area 5. It did not appear that 17,538 sf of buffer was preserved adjacent to RA 5, but rather an amount likely less than 3,000 sf based on visual estimates. Although preserve buffer is absent in this area, total buffer area on the site exceeds 78,844 sf (i.e. the amount of PVC needed to meet the second half of mitigation requirements for the project). As with other replacement areas on the site, a diverse native buffer was established adjacent to the existing wetland as described in Table 4. Table 4.

Hydrology was to be supplied by groundwater and shared hydrology from the adjacent wetland. Based on the delineation a total 8,215 sf of NWC was established in RA 6 (Figure 4C). At the time of the site visit, approximately 90 percent of the wetland was inundated with 3 to 12 inches of water and the remainder was saturated. The highest portions of RA 6 were -' dominated by fowl bluegrass and green bulrush and the lower portions by cattail and spikerush. Details of the observed plant community are included in Figure 15. Buffer Description A total of 7,628 sf of buffer was proposed adjacent to the north and west sides of RA 6. Buffer adjacent to RA 6 consists of the plant community similar to that described in Table 4. Sweet clover observed the previous year was absent or possibly mowed and not visible. Again, a wood chip trail was observed through portions of the buffer and a small area around the buffer post is planted in sod. Overall these encroachments represent less than 100 sf of buffer. Replacement Area 7(RA 7) (Figures 17 and 18) A total of 76,882 sf of NWC was to be created adjacent to existing wetland by excavating to elevations ranging from 947.0 to 950.0 msl to create saturated and emergent wetland that blended with the original wetland edge. Hydrology was to be supplied by groundwater, surface runoff, and shared hydrology from the adjacent wetland. Based on the delineation a total 77,925 sf of NWC was established in RA 6 (Figure 4). At the time of the site visit approximately 80 percent of the basin was inundated with 3 to 8 inches of water, and the remainder was saturated. The highest portions of the wetland were dominated by fowl bluegrass and big bluestem and lower portions by cattail, spikerush, and fowl bluegrass. Details of the observed plant community are included in Figure 17. Buffer Description A total of 30,492 sf of buffer was proposed adjacent to the east edge of the new wetland. _ At the time of the site visit, the buffer plant community was mowed to the wetland edge. This area lacks wetland signage, and mowing was probably performed by County roadway workers. VI. DISCUSSION Table 6 summarizes the actual amount of NWC established on the site and has been updated from the 2008 report regarding the area of RA 3. Buffer PVC was not calculated. It is assumed that sufficient PVC has been established on site from the combination of stormwater ponds, native buffer and preserved buffer areas which was proposed to total 181,125 sf (4.16 acres), 102,281 sf (2.35 acres) in excess of required PVC replacement.

Because the area of RA 3RA 3 is not needed to fulfill mitigation requirements, RA 3 will no longer be monitored. VII. MANAGEMENT ISSUES/RECOMMENDATIONS • Prairie Restorations should continue spot herbicide applications to weedy and invasive species in all Replacement Areas — except Replacement area 3 - through the 2010 growing season. Particular attention is needed in buffer adjacent to Replacement Area 6 and both wetland and buffer areas of Replacement Area 7. • Replacement Area 3 will no longer be monitored due to a lack of hydrology. Vegetation management will continue with the exception of herbicide treatments for reed canary grass control. • Permanent buffer signs should be installed adjacent to all replacement wetlands to deter future encroachment or accidental mowing. 8 Hunters Pass Albertville, Minnesota Figures: Figure 1: Site Location Map Figure 2: Grading Plan Figure 2A: Mitigation Detail Figure 2B: Mitigation Detail Figure 3: Buffer Areas Figure 4: GPS-Located Wetland Boundaries Figure 4A: As -built delineation -RA 1 & 2 Figure 4B: As -built delineation -RA 4 & 5 Figure 4C: As -built delineation -RA 6 Figure 5: Replacement Area 1 Data Sheets Figure 6: Replacement Area 1 Photographs Figure 7: Replacement Area 2 Data Sheets Figure 8: Replacement Area 2 Photographs Figure 9: Replacement Area 3 Data Sheets Figure 10: Replacement Area 3 Photographs Figure 11: Replacement Area 4 Data Sheets Figure 12: Replacement Area 4 Photographs Figure 13: Replacement Area 5 Data Sheets Figure 14: Replacement Area 5 Photographs Figure 15: Replacement Area 6 Data Sheets Figure 16: Replacement Area 6 Photographs Figure 17: Replacement Area 7 Data Sheets Figure 18: Replacement Area 7 Photographs Note: Site boundaries on this figure are approximate and do not constitute an official survey product. v Site Location y St NE z M J Otsego m e m 70th St NE #h St JL, w z 527 r(_ L a) w G-r St. Michael'I Figure 1— Site Location Map c' KJOLHr ��Tr�r AUG ENVIRONMENTAL SERVICES COMPANY yv Hunters Pass (KES No. 2009-002) Albertville, Minnesota +N No Scale ROM M;7`I xzt�i x 1 � 1 1 0 � Q�jJ QQ$M$$Qp'}MM}qiii,,,, OMO� \\ � �•.\\\\ \��`\ e � j 4/ <� \`2=® ��Y' \\ � Rif gill-3 4 cv A.

Subpart 1. General requirements. The standards and guidelines in this part shall be _ used in wetland creation and restoration efforts to ensure adequate replacement of wetland functions and values. In evaluating a wetland replacement plan, the local government unit must determine whether the wetland type stated as the replacement plan goal will result from the replacement plan specifications. If a wetland type other than the replacement plan goal is likely to result, the local government unit must evaluate the plan based on this determination. The local government unit must also determine that the proposed replacement plan will adequately replace functions and public values lost. If adequate replacement and public value is not likely to result, the local government must determine what further measures are necessary to obtain adequate replacement or deny the replacement plan. Subp. 2. Specific requirements. The standards in items A to H shall be followed in all wetland replacements unless the technical evaluation panel determines that a standard is clearly not appropriate. A. Water Control structures must be constructed using specifications provided in the Minnesota Wetland Restoration Guide or their equivalent. Control structures may be subject to the Department of Natural Resources dam safety regulations. B. Best management practices must be established and maintained adjacent to the entire perimeter of all replacement wetlands. C. For replacement wetlands where native, noninvasive vegetation that is characteristic of the wetland type identified as the replacement goal in part 8420.0530, item D, is not likely to become dominant naturally in a five-year period, the replacement wetland shall be seeded or planted with appropriate native, noninvasive species, as determined by the technical evaluation panel. If the replacement wetland is seeded or planted, the seed or planting stock should be from native, noninvasive species of regional wetland origin. During the monitoring period, the applicant must take reasonable steps to control invasion by any nonnative or invasive species, for example, reed canary grass, Canada thistle, common buckthorn, spotted knapweed, leafy spurge, purple loosestrife, and Eurasian water milfoil, that would defeat the revegetation goal of the replacement plan. D. Erosion control measures as determined by the soil and water conservation district must be employed during construction and until permanent ground cover is established to prevent siltation of the replacement wetland or nearby water bodies. E. For all restored wetlands where the original organic substrate has been stripped away and for all created wetlands, provisions must be made for providing and organic substrate unless the technical evaluation panel recommends otherwise. When feasible, the organic soil used for backfill should be taken from the drained or filled wetland dominated by native, noninvasive species. Organic soils for backfill from wetlands dominated by normative, invasive species should be avoided. F. The bottom contours of created types 3, 4, and 5 wetlands should be undulating, rather than flat, to provide a variety of water depths, comparable to natural wetlands in the vicinity or the replacement, and be consistent with part 8420.0547, subpart 2. G. Sideslopes of created portions of wetlands and graded buffer strips must not be steeper than 5:1, five feet horizontally for every one foot vertically as averaged around the wetland. Sideslopes of 10:1 to 15:1 are preferred. More than half of the slopes of graded areas inside the exterior boundaries of restored, created, or enhanced wetlands must be no steeper then 10:1 unless the technical evaluation panel concurs that steeper slopes are acceptable. H. Created wetlands should have an irregular edge to create points and bays, consistent with part 8420.0547, subpart 2.
