The purpose of this report is to identify the impacts of the proposed parking improvements and how they will relate to the storm water management system currently installed on the Opus site. The detention design of this site is governed by the City of Carmel and Hamilton County. City of Carmel standards were used for the storm sewer and water quality design. 1.1 Project Description The proposed improvements are located within the 13.95 acre Phase 1 North portion of the approximate 23.6 acre Opus North Corporation property. The project will consist of the reconstruction of an existing drive, and the addition of new parking areas as master planned within the first phase of the development. The disturbed area within the parcel is approximately 2.61 acres of the 13.95 acre Phase 1 property. 1.2 Scope of Report This report summarizes the design for the additional parking areas and the reconstructed drive as it relates to the Phase 1 master plan versus overall storm water management system as designed in the Woolpert Drainage Reports dated September 2005 and the supplement dated October 2005. 1.3 Existing Conditions lJ U U U U U U The existing developed site drains to the existing pond where it is detained and ultimately drains South throLi9h a temporary swale and then to two 21" CMP pipes under West Carmel Dr. The remainder of the site drains directly to the temporary swale and then out the 21" CMP pipes. The adjoining properties consist of the following: North: Hotel (82) South: Commercial Strip Mall (82) East: Assisted Living Facility (OM/MF) West: US 31 (Freeway) The soils maps from the US Department of Agriculture, Soil Conservation Service identifies the tributary watershed to contain three soils classifications. These are: Brookston silty clay loam (Sr) and Crosby Silt loam (CrA). 1 0:\ 1999\990399\20200\docs\Engr\Reports\Drainage Report_revised, DOC o [J D o o u u o The Firm map panel numbers 18057C0206F and 18057C0207F dated February 19, 2003, indicate that the site lies in Flood Zone "Xli. These areas are considered to be outside of the 500 year floodplain. 2.0 Pre-developed Conditions 2.1 Pre-developed Site Conditions Allowable Release Rates In the Phase 1 drainage report supplement to the master plan for the Opus North Corporation site done by Woolpert LLP, the existing pond may release up to 2.95 cfs to the existing temporary swale that runs south and ultimately to the twin 21" CMP pipes. This model included 13.95 acres, a time of concentration of 10 min. and a weighted curve number of 90 for the contributing watershed to the wet pond. Please refer to Appendices D and E for the drainage analysis calculations completed by Woolpert LLP. 3.0 Post-Developed Drainage Analysis o u u o U D o D o U 3.1 Post-developed Site Conditions The post-developed drainage analysis consists of a storm sewer network designed to take the proposed parking areas to the existing pond, and, an analysis of the current system as it relates to the Phase 1 master planned storm water management system. The current contributing watershed for the existing pond as updated by the proposed parking areas and storm sewer network is as follows: Area = 9.48 acres Weighted CN = 92 Time of concentration := 10 min. Per the design data by Woolpert, the impact of the additional parking areas continues to follow the Phase 1 master plan design. To accomodate for the higher eN, the future buildout of Phase 1 will contain more grass areas. See Appendix A for Phase 1 Basin map. 3.2 Storm Sewer Network Stormcad was utilized to size the storm sewers using the Rational Method. The 10 year event is contained within the crown of the pipes and the 100 year within the casting of the structure. The storm water will not stage to an elevation that will surcharge the inlets. The pipes are oversized to provide the opportunity for future build out of the site. (See calculations and the inlet basin exhibit in Appendix C). 2 11 U 0\ 1999\990399\20200\docs\Engr\Reports\Drainage Report_revised. DOC ~ ~ J I IJ I :J I ^1 , I IU ~ , I ILl I 4.0 Water Quality Analysis The improvements were analyzed for the provision of water quality. The water quality Best Management Practice (BMP) structure is sized based on the Water Quality Treatment rate. The water quality treatment rate was determined by using hydrograph generation methods. The peak treatment flow calculated for the BMP structure is 2.73 cfs. To treat this flow, a VortSentry HS72 BMP has been detailed. The hydrograph utilized the SCS Type II distribution for 1 inch of rainfall in 24-hours. (See detailed calculations in Appendix B). IJ I IU , I J J J J J U U U U o 5.0 Conclusions The eXisting detention pond contains sufficient storage volume to accept the additional parking areas added to Building #1 on the Opus North Corporation site. The proposed storm drainage system complies with the Phase 1 report and the overall master plan design. There are no adverse impacts anticipated by this design. 3 0:\ 1 999\990399\20200\docs\Engr\Reports\Drainage Report_revised.

At present, the site is an open grassy meadow with a line of trees and bushes along the west side of the property. There is one existing pond located on the soutb end of the site that will be utilized for stann water detention. Soil types present ansite .include Crosby silt loam and Brookston silt loam. The site currently drains south into the existing pond and then continues south through twin 21" corrugated metal pipes. The allowable release rate from the twin 21" CMP's into the existing manhole south of West Carmel Drive is 5.0cfs. This release rate was set forth in the drainage study "Addendum to Stormwater Management Design Calculations on Hamilton Crossing" dated June 1, 1989 prepared by Paul I. Cripe and Associates. Release rate restrictions were placed on this site, the Duke property to the south, the Meijer property to the east, and Meridian Crossing to the west across U.S. 31. This was due to historical accounts of Permsylvania Street overtopping during intense rainfall events. This drainage analysis follows the drainage designs that wefe done for the Meijer property to the east and the Hamilton Crossing East development to the south. According to the FEMA Flood Boundary and Floodway Map, Community Panel 180081 0007 C, the site does not lie in a floodplain. Proposed Conditions The proposed improvements include three multi-story office buildings, parking areas, two detention ponds, storm and sanitary sewers, and other associated utilities. The entire site will drain to the two proposed detention ponds, located on the west side of the property, ttrrough a storm sewer network. Pond A will flow south to Pond B through a 12" reinforced concrete pipe. AnS" orifice plate on the end of the pipe controls flow through this connecting pipe. In order to prevent flooding, due to the orifice being clogged, an emergency overflow weir will be placed at the 1 OO-year pond elevation of 866.27 ft. Flow from Pond B will be controlled through a 10" orifice plate placed on the end of the 18" reinforced concrete pipe. There will also be an emergency overflow weir placed at the 1 DO-year pond elevation of 861.07 f1. The 18'l pipe will connect to the twin 21" CMP culverts that will be enclosed within proposed manholes. A proposed watershed map for this site can be found in Section 4 of this report The ponds were analyzed using the SCS Method and the Advanced IntercolU1ected Channel and Pond Routing (AdICPR) program version 2.11. The interconnected ponds are designed to regulate the IOO-year, 24-hour rainfall event to the 5.0cfs release rate. This design releases 3.68cfs into the existing twin 21" eMP culverts at the south end of the site. This is 1.32cfs less Woolpert July 2000 Opus landmark at Meridian Opus North Corporation u u u u u U D o U o U D j- -\ U o D U U U U than the restrictive release rate set forth by PaulL Cripe and Associates in their drainage study "Addendum to StOmlwater Management Design Calculations on Hamilton Crossing" dated June 1, 1989. Pond A Pond B Normal Pool 86400 858.70 Acreage 1.67 1.05 Volume (Ac-ft) Release Rate (cfs) 1.63 3.68 The site was divided up into two sub-basins, N-BLDGS and S-BLDG. This was done to detennine what area was going to each pond. The time of concentration was found for each individual basin by assuming travel time over grass and pavement. The runoff value was calculated to be 91 for both drainage basins. Time of concentration calculations and runoff values for each of the sub-basins can be found in Section 2 ofthis report. Conclusion The developmem of this property includes three multi-story office buildings, parking areas, the extension of all necessary utilities, and the reduction of the storm water outflow to help reduce flooding of Pelillsy lvania Street. The proposed development of Opus Landmark at Meridian has been designed in accordance with the Drainage Report for the Hamilton Crossing East development dated November 1998. The post-developed release rate of 3.68cfs is less than the release rate of 5.0cfs set forth in the drainage study by PaulL Cripe and Associates, therefore, no adverse impacts are anticipated from this development.

Approximately O.4~ acres of wetlands were identified OIl the site. 1.2 This report identifies the jurisdictional status of the project area based on J.F. New & Associates' best professional understanding and interpretation of the Corps of Engineers Wetland Delineation Manual (1987) and Corps of Engineers guidance documents and regulations. Jurisdictional determinations for other "waters ofthe United States" were made based on definitions and guidance found in 33 CFR 328.3, Corps Regulatory Guidance Letters, and the wetland delineation manual. The Corps of Engineers administers Section 404 of the Clean Water Act which regulates the discharge of fill or dredged material into all "waters of the United States, II and is the regulatory authority that must make the final determination as to the jurisdictional status of the project area. 2.0 REGULA TORY DEFINITIONS 2.1 Waters of the United States "Waters of the United States" are within the jurisdiction of the Corps of Engineers under the Clean Water Act. "Waters afthe United States" is a broad term which includes waters that are used or could be used for interstate conunerce. This includes wetlands, ponds, lakes, territorial seas, rivers, tributary streams including any definable intermittent waterways, and some ditches below the "Ordinary High Water Mark (OHWM.)." Also included are manmade waterbodies such as quarries and ponds which are no longer actively being mined or constructed. Wetlands, mudflats, vegetated shallows, riffle and poot complexes, corat reefs, sanctuaries and refuges are all considered special aquatic sites which involve more rigorous regulatory permitting requirements. A specific, detailed definition of "Waters ofthe United States" can be found in the Federal Register (33 CFR 328.3). 2.2 Wetlands Wetlands are a category of "waters of the United States" for which a specific identification methodology has been developed. As described in detail in the Corps of Engineers Wetland Delineation Manual (1987), wetland boundaries are delineated using three criteria: hydrophytic vegetation, hydric soils, and wetland hydrology. J,P, New & ASSOCIates, Inc, IFNA File# OQ..o6-04 Page I u u u u,s- 31 and 126m Street Hamilton County, Indiana July 4,2000 u u u u U J U U. U U [J U o U o 2.2.1 Wetland VegetatioR In the course of developing the wetland determination methodology the Corps, in cooperation with the U.S. Fish and Wildlife Service, Environmental Protection Agency and the Soil Conservation Service, compiled a comprehensive list of wetland vegetation. The indicator status of plant species is expressed in terms of the estimated probabilities of that species occurring in wetland conditions within a given region The indicator categories as defined by the Corps are: u Obligate Wetland (OBL) Occur almost always (estimated probability >99%) under natural conditions in wetlands. F acultative Wetland (FACW) Usually occur in wetlands (estimated probability 67%- 99%), but occasionally found in non-wetlands. Facultative (FAC) Equally likely to occur in wetlands or non-wetlands (estimated probability 34%~66%). Facultative Uoland (F ACU) Usually occur in non-wetlands, but occasionally found in wetlands (estimated probability 1%-33%) Obligate Upland (UPL) Occur almost always (estimated probability >99%) in uplands. Plants which are OBL, F ACW and F AC (except F AC~) are considered wetland species. Positive or negative signs indicate a tendency toward higher (+) or lower (-) frequency of occurrence within a cat~gory. The percentage of the dominant wetland species in each of the vegetation strata in the sample area determines the hydrophytic or wetland status ofthe plant community. Soil type and hydroperiod are two factors important in controlling species composition 2.2.2 Hydric Solls. Hydric soils are defined as soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part. In general, hydric soils are flooded, ponded, or saturated for a week or more during the growing season when soil temperatures are above 320 F. The anaerobic conditions created by repeated or prolonged saturation or flooding results in permanent changes in soil color and chemistry which are used to differentiate hydric from non-hydric soils. In this report, soil colors are described using the Munsell notation system. This method of describing soil color consists of separate notations for hue, value, and chroma which are combined in that order to form the color designation. The hue notation of a color indicates its relation to red, yellow, green, blue and purple; the value notation indicates its lightness, and the chroma notation indicates its strength or departure from a neutral ofthe same lightness J.F, New & Associates, Inc. JFNA Filet! 00-06-04 Page 2 u' u o u [J u.s. JJ and 126\h Street Hamilton County, Indiana July 4,2000 The symbol for hue consists of a number from 1 to 10, followed by the letter abbreviation of the color. Within each letter range, the hue becomes more yellow and less red as the numbers increase. The notation for value consists ofnurnbers from 0 for absolute black, to ] 0 for absolute white. The notation for chroma consists of numbers beginning with 10 for neutral grays and increasing at equal intervals. A soil described as IO"YR 3/1 soil is more gray than a soil designated IOYR 3/6. The Corps of Engineers color criteria for hydric soils specifY that the chroma must be /1 if the soil has no mottles (small variations in color), and /1 or /2 if the soil is mottled. u 2.2.3 Wetland Hydrology. Wetland hydrology is defined as the presence of water for a significant period of time at or near the surface (within the root zone) during the growing season. Wetland hydrology is present only seasonally in many cases, and is often inferred by indirect evidence. Hydrology is controlled by such factors as seasonal and long-term rainfall patterns, local geology and topography, soil type, local water table conditions, and drainage. Primary indicators of hydrology are inundation, soil saturation in the upper 12" ofthe soil, water marks, sediment deposits and drainage patterns. Secondary indicators such as oxidized root channels in the upper 12" of the soil, water stained leaves, local soil sUIVey data and F AC-neutral vegetation test are sometimes used to identify hydrology, A primary indicator, or two or more secondary indicators are required to establish a positive indication of hydrology. '-1 U [J o o o o o u o o u o u 2.2.4 Wetland Definition Summary. In general, an area must meet all three criteria to be classified as a wetland. In certain problem areas such as seasonal wetlands which are not wet at all times, or in recently disturbed (atypical) situations, areas may be considered a wetland if only two criteria are met. In special situations, an area which meets the wetland definition may not be within the Corps of Engineers jurisdiction due to a specific regulatory exemption. 3.0 BACKGROUND INFORMATION 3.1 Existinz mal)S Several sources of information were consulted to identify potential wetlands and wetland soil units on the site. These include the U.S. FiSh and Wildlife Service's National Wetland Inventory (NWI) and the Natural Resources Conservation Service's (NRCS) Soil Survey for this county. These maps identify potential wetlands and wetland soil units on the site. The NWI maps were prepared from high altitude photography and in most cases were not field checked. Because of this, wetlands are sometimes erroneously identified, missed, or misidentified. Additionally, the criteria used in identifYing these wetlands were different from those currently used by the Corps of Engineers. The county soil maps, on the other hand, were developed from actual field investigations- However, they address only one of the three required wetland criteria and may reflect historical conditions rather than current site conditions. The resolution of the soil maps limits their accuracy as well. The J.F, New & Associates, Inc. JFNA File# 00-06-04 Page 3 u o u u.s. 31 and l26th Street Hamilton COlmty, Indiana July 4, 2000 o o u o u u u o o o o U D o U I 10 I mapping units are often generalized based on topography and many mapping units contain inclusions of other soil types for up to 15% of the area ofthe w1it. The Corps does not accept the use of either of these maps to make wetland determinations. 3.2 NWl mav The National Wetland IrNentory map of the area (Figures 2 and 3) identifies one wetland centrally located within the project boundary as a palustrine emergent temporarily flooded (PEMA). 3.3 Soil SUJ}lev The NRCS Soil Survey of Hamilton County (Figure 4) identifies two soil series on the site: Brookston silty clay loam (Br) and Crosby silt loam, 0 to 3 percent slopes (erA). According to Hydric Soils of Indiana by County, the Brookston soil series is dominated' by hydric components, while the Crosby soil series contains hydric components. 4.0 SITE INVESTIGATION & DESCRIPTION 4.1 Investization Methodology The delineation of wetlands and other "waters of the U.S. II on the site was based on the methodology described in the Corps of Engineers Wetland Delineation Manual (Technical Report Y-87-1) as required by current Corps of Engineers policy. Prior to the field work, the background information was reviewed to establish the probability and approximate location of wetlands on the site. Next, a general reconnaissance of the project area was made to determine site conditions. The site was then walked with the specific intent of determining wetland boundaries. Data stations were established at locations within and near the wetland areas to document soil characteristics, evidence of hydrology and dominant vegetation. Note that no attempt was made to examine a full soil profile to confirm any soil series designations. However, soils were examined to a depth of at least 16 inches to assess soil characteristics and site hydrology. Complete descriptions of typical soil series can be found in the soil survey for this County. 4.1.1 Site Photographs. Photographs ofthe site are located in Appendix A. These photographs are the visual documentation of site conditions at the time of inspection. The photographs are intended to provide representative visual samples of any wetlands or other special features found on the site inspected 4.1.2 Delineation Data Sheet. \\There stations represent a wetland boundary point they are presented as paired data sheets, one each documenting the upland and wetland sides of the wetland , boundary. The distance the specific upland or wetland stations are from the boundary point is noted on the data sheet. Approximate data station locations are located on Figure 5.

These forms are the written documentation of how representative sample stations meet or do not meet each of the wetland criteria. Other points were also inspected during the delineation process but were not specifically recorded on data sheets. I I U 4.1.3 Wetland Boundary Survey. A survey of the wetiand locations is included as Figure 6. I U 4.2 General Site Condition.'i The site is located at the northeast corner of the intersection of U S. 31 and 126th Street and was delineated by I.F. New and Associates on June 19,2000. The majority of the property consists of cropland with a small clump of trees in the central portion of the site. The clump of trees was investigated for wetland characteristics and is described in detail below as Community A. The site also contains a fence line 011 the west boundary that contains moderate to large sized trees and shrubs. One open water/emergent type wetland area was identified, Wetland A, in the south portion of the property boundary and is described in detail below. J I J J 4.3 Technical DescriTJtions , W ctLand A This area is located in the south portion of the subject site, on the north side of 126[h Street (Figure 5). The littoral shelf and bank of the open water system is dominated by shrubby plant species such as black willow (Salix nigra, OBL) and gray dogwood (Comus racemosa, FACW-). Herbaceous species consisted of pond weed (Potamogeton sp., OBL), swamp milkweed (Asclepias incarnata, OBL), spikerush (Eleocharis sp. OBL) and short beaked sedge (Carer breviar, FAC). u J J u u Soils within the wetland area, Test pit A-I, were not examined due to inundation. Test pit A-2 exhibited a matrix color oflOYR4/4 with few mottles ofl0YR 5/4 to a depth of8 inches and lOYR 6/3 with many mottles of 10YR 5/8 to a depth of 16 inches. Hydrological indicators consisted of inundation and drift lines. Results of the FAC-neutral test also indicate that wetland hydrology is present. r--' I I U Community A This area was investigated in detail due to it's proximity to the wetland area depicted on the 1\TWI map. This community is defined by the presence of mature silver maple (Acer saccharinum, F ACW) and gray dogwood (Comus racemosa, FACW-) within the central portion of the fannland. Hackberry (Celtis occidentalis, FAC-) and white mulberry (Moros alba, FAC) are also located within this COIT'J1lunity. The groundcover within tpis small clump of trees consists of garlic mustard (Alliaria petiolata, FAC) and poison ivy (Toxicodendron radicans, FAC+). The type of plant species dominating this community meets the first ofthe three criteria to be considered a wetland. LJ U U o J.F. New & Associates, Inc. JFNA FiJe# 00-06-0'1 Page 5 u u u U.S. 31 and 126L'I Street Hamilton County, [ndiann July 4,2000 u U U U U U D D D o U o U o U o U Soils within this wetland area exhibited a matrix color of IOYR 3/1 to a depth of6 inches and a color of lOYR 3/2 to a depth of 16 inches for test pit B-1, which does not meet the hydric soil criteria (Figure 5). Results of the FAC-neutral test and soil survey data are the only signs of hydrological indicators. However, only two secondary types of hydrological indicators are needed to meet the second criteria. Although the vegetation and hydrology portions appear to meet the criteria, all three criteria must be met to be considered a wetland. It appears that this community does not meet'all three criteria and is not considered a jurisdictional wetland area. '. 5.0 JURISDICTIONAL ANALYSIS 5.1 Corps of Engineers The Corps of Engineers has authority over the discharge of fill or dredged material into "waters of the United States." This includes authority over any filling, mechanical land clearing, or construction activities that occur within the boundaries of any "water of the United States." A permit must be obtained from the Corps of Engineers before any of these activities occur. Permits can be divided into three general categories: Individual Permits, Nationwide Pennits and the Regional General Permit for Indiana. The Regional General Permit for Indiana authorizes activities associated with the construction or installation of new facilities or structures as well as for agriculture or mining. Proposed wetland impacts must be less than 1 acre and meet specific criteria in order to qualify for these permits. Section 401 Water Quality Certification must be obtained from the Indiana Department of Environmental Management before the Corps will perform their permit review. Nationwide Permits have been developed for proj ecis which meet specific criteria and are deemed to have minimal impact on the aquatic environment. Individual Permits are required for projects that do not faU into one ofthe specific Nationwide Permits or the Regional Genera! Permit or are deemed to have significant environmental impacts. These permits are much more difficult to obtain and receive a much higher level of regulatory agency and public scrutiny and may require several months to more than a year for processing. 5.2 Other agencies The Indiana Department of Environmental Management (IDEM) is responsible for issuing Clean Water Act Section 401 pennits known as Water Quality Certification (WQc) in conjunction with Corps 404 permits. For some situations, IDEM has pre-approved WQC; but for most wetland impacts greater than 0.1 acre, a separate application for WQC must be submitted directly to IDEM. The Indiana Department ofNarural Resources (IDNR) has jurisdiction over thefloodway of ditches and streams with a watershed greater than one (1) square mile. If impacts are proposed to jurisdictional floodways, a Construction-In-A-F1oodway permit may be required from the IDNR. J.F. New & Associ~les, Inc.

SECTION 3 .. . I .J OpDs L:ihdinilr'i. ;it Meridian Opus North corpora lion Woolpert July 2005 U J DRAINAGE REPORT u u u u u u u o u U D o U o Existing Conditions The existing 23.64-acre site is located in the northwest quadrant of the intersection of West Carmel Drive and Pennsylvania Street in the City of Carmel, Hamilton County, Indiana. At present, the site is an open grassy meadow with a line of trees and bushes along the west side of the property. There is one existing pond located on the south end of the site that has been designated as existing wetlands. Soil types present onsite include Crosby silt loam and Brookston silt loam. The site currently drains south into the existing pond and then continues south through twin.2!" corrugated metal pipes. The allowable release rate from the twin 21" CN.!P's into the existing manhole south of West Carmel Drive is 5.0cfs. This release rate was set forth in the drainage study "Addendum to Stormwater Management Design Calculations on Hamilton Crossing" dated June I, 1989 prepared by PaulL Cripe and Associates. Release rate restrictions were placed on this site, the Duke property to the south, the Meijer property to the east, and Meridian Crossing to the west across u.s. 31. This was due to historical accounts of Pennsylvania Street overtopping during intense rainfall events. According to the FEMA Flood Boundary and Floodway Map, Community Panel 180081 0007 C, the site does not lie in a floodplain. Proposed Conditions The proposed improvements include two multi-story office buildings, parking areas, expansion of the existing detention pond, stonn and sanitary sewers, and other associated utilities. This construction will take place on the northern portion of the overall site. Therefore, the proposed detention will be for this portion of the development as well as the existing building on the north side of the property. The release rate from the proposed pond will be held to 2.95cfs or less which is 59%, 13.95 Acres, of the allowable 5.0cfs for the overall site. This corresponds to the percent of the property that is being disturbed with this current development and the existing north building. u The majority of the site will drain to the proposed detention pond, located on the west side of the property, through a storm sewer network. A small portion of yard area, approximately 0.4 acres, south ofthe pond will direct discharge into the temporary channel. Pond A will outlet into a temporary channel that flows south to the existing twin 21-inch pipes under Carmel Drive. A 7- inch orifice plate will be placed on the outlet pipe from the pond to control the flow into the temporary channel to 2.35cfs. The total flow to the temporary channel is l.92efs. This is less than the allowable 2.95cfs described above. In order to prevent flooding, due to the orifice being clogged, an emergency overflow weir will be placed at the 1 OO-year pond elevation of 867.86 ft A proposed watershed map for this site can be found in Section 2 of this report o u Woolpert October 2005 Opus Landmark at Meridian Opus North Corporation u u U D U U The ponds were analyzed using the SCS Method and the Advanced Interconnected Channel and Pond Routing (AdICPR) program version 3.02. The pond is designed to regulate the lOO-year, 24-hour rainfall event to 2.92efs into the temporary channel that flows to the existing twin 21" CMP culverts at the south end of the site. This is O.03cfs less than the 2.95cfs restrictive release rate described above. U D D o D LJ J [J J J '> ?OClc.\.~np\c.ns :; 0,'1 S e-c Time of concentration calculations and runoff values for the overall basin can be found in Section 2 of this report. The time of concentration was assumed to be 5 minutes Jor all storm sewer calculations and the ronoffvalue was taken as 0.85. Release Rate (cfs) 2.35 Pond A Conclusion The development of this property includes two multi-story office building, parking areas, the extension of all necessary utilities, and the reduction of the storm water outflow to help reduce flooding ofPennsylv3nia Street. The proposed development of Opus Landmark at Meridian has been designed in accordance with the Drainage Report for the Hamilton Crossing East development dated November 1998. The post-developed release rate of 2.92cfs, for the north portion of the site is less than 2.95 efa, the percent ofthe allowable release rate of 5.0cfs set forth in the drainage study '"Addendum to Stormwater Management Design Calculations on Hamilton Crossing" dated June I, 1989 prepared by Paul 1. Cripe and Associates. Therefore, no adverse impacts are anticipated from this development. J U U Woolpert Odober 2005 Opus Landmark.81 Meridian Opus North Corporation o D ." . _ __.~r::./ ,.

The submittal is in need of additional information in order to be in compliance with the guidelines as set forth by the City of Cannel. Please revise the plans in accordance with the comments below. o 1. The drainage report refers to "Addendum to Stormwater Management Design Calculations on Hamilton Crossing"ciated June 1, 1989, prepared by Paull Cripe. Please provide a copy of this document to confirm release rate of 5.0 cft for the twin 21-inch storm pipes under West Carmen Drive. This issue has been addressed satnfactorily. 2. The construction plans show "FUTURE/POSSIBLE INDOT RiGHT-OF-WAY" for us. 31 along the west side of the site, which includes approximately two- thirds of the proposed detention area. Please add a note to the construction plans stating that detention is for Phase I & II only and that Phase III shall be handled separately, and include with this note that in the event INDOT obtains this right- of way, the owner of the property shall be responsible for maintaining adequate detention storage. This issue has heen addressed satisfactorily. 3. Sheet C602 provides a Lake Section detail. Please confirm that this detail conforms to the minimum requirements of the Hamilton County Surveyor's Office as shown in Standard Plans D-6, D-7 or D-8, "Lake Cross-Sections ". Per your response letter dated September 13) 2005, the 1 GO-year flood elevation changes osl-'.'ell as the lOG-year discharge rate. Although your plans reflect this change, the drainage narrative has not been revised. To avoid confusion, please review and revise the drainage narrative information accordingly. 4. Please provide calculations for the post-developed time of concentration. This issue has been addressed satisfactorily. 5. Please provide peak runoff calculations for the 2-year and the 10-y"ear storm events. This issue has been addressed satisfactorily. u u u u o o u u u Opus LfIIldmark at Meridian Wool~ert, Inc. O~tober 12, 2005 . PD/(e I of 4 3417 Soul:h Sherman Dr. . DeE"t:h 6rDve, IN 46107 a Tel 317a7BO 01555 . Fax 3 T7D7BOa65i'!5 .". u u u 6. The drainage calculations refer to the detention area as Pond A, whereas the construction plans refer to the detention area as Pond B. Please revise accordingly. This issue has been addressed satisfactorily. 7. The End Cap Detail on sheet C60i shows a 4-inch diameter orifice on a i2-inch diameter pipe. The drainage report states and the drainage calculations corroborate the orifice being a 7-inch diameter with no pipe diameter specified. Please revise this detail accordingly. This issue has been addressed satisfactorily. 8. There is some concern regarding the outlet male and it's considerably flat slope (0.40%) combined with its length (1318 feet). The minimum slope for a grass- lined swale shall be 1.0 percent, and the minimum slopefor a grass-lined swale with a sub-surface drain is one-half percent. Drainage swales shall not exceed 400 feet. Please investigate methods of reducing standing water within the swale. The City of Carmel may comment on this as well and offer measures typically implemented. This issue has been addressed satisfactorily. 9. Please delineate the drainage basins on the drainage basin map provided Thi.. lssue has been addressed satisfactorily. 10. It appears that basin 24 has been mislabeled on the drainage basin map as basin 29. Please review and revise accordingly. This issue has been addressed satisfactorily. 11. Please include the rainfall intensity tablelchart used in the drainage calculations with the drainage report support documentation. This issue has been addres!,ed satisfactorily. J 2. Based on the velocities provided in the drainage calculations, Structures J 3, J 6, 17, 26, 29, 31, 32 and 33 do not meet minimumfulljlow velocity requirements. Minimum storm drainflowing velocity for full pipejlow shall be 2.5 feet per second This issue has been addressed satisfactorily. 13. Please provide hydraulic grade line calculations with the drainage report. Hydraulic grade line calculations are to be included as a part of the storm calculations submittal. The hydraulic grade line calculations should be provided to demonstrate (hat the maximum hydraulic grade line stays below inlet/manhole rim elevations for a 10-year storm event. This issue has been addressed satisfactorily. 14. It appears that there is direct run()ff west of building 2, south of the detention area. Direct runofffrom the site needs to be accommodatedfor appropriately. The direct runoffrates need to be added to the release rates developed for the post 1 aD-year and 10.year storms to determine the total peak runoff rate leaving the site. It appears that the plans have been preparedfor Phase I of this project only. The detention pond, which has been designed to accommodate Phase I and Phase II, mus/be constructed as a part of Phase Ifor acceptance. The release rate for the detention pond has been de~igned to include the acreagefor both Phase I and II. There is approximately 1 acre of the 12.9- acre tract in the southwest corner of Phase II thai is not being detained and is directly Opus Landmark al Meridian Woolpen. Inc. October l2, 2005 Page 2 of 4 u o u o u u D o o [J o o u u u u u o discharging south along the proposed outJet swa/e. Tllis discharge needs to be accounted for in the overall discharge ratefor the 12.9-acre tract. The discharge rate at the point the proposed outlet swale leaves the south line of Phase II should not exceed the 2.73 cIs release rate. 15. For any lo/(s) adjacent to any] aO-year local or regional flood area, a minimum flood protection grade (MFP. G.) is required for the pad grade. Please define the MFPG in the construction plans with a statement such as: "Finished floor elevations of all structures shall be no less than 2 fiet above any adjacent] OO-yr local or regional flood elevation (whichever is greater). This issue has been addressed satisfactorily. 16. Drainage arrows shall be provided indicatingjlow direction. Please review and revise accordingly. This issue has been addressed satisfactorily. 17. Normal pool,. 2-year, lO-year and 100-year critical flood elevations shall be provided on the drainage plans. The drainage calculations snow the lOO-year critical flood elevation as 867. 95 whereas the plans show this elewition as 867.69. Please review and revise accordingly. This issue has been addressed satisfactorily. 18. There is no structure data information provided in the construction plans. Please incorporate this information in the construction plans. Please include on sheet C400 structure information to include rim and invert elevations, length, diameter, type and slope of each pipe structure, to include Structure 35. This issue has been addressed satisfactorily. 19. The construction plans do not show the location of the spillway/emergency overflow weir, which should be clearly marked on the drainage plans. The flood route shall be clearly marked on the plans and should be addressed in the drainage report for clarification. Assurances should be made that overflow is conveyed to an aqjacent road ditch or water body in the event that a storm in excess of a lOO-year event occurs or the outlet structure becomes clogged and the pond backs up to a level where the '!'pillway becomes functional. Please review and revise. This issue has been addressed satisfactorily. 20. The Overflow Weir Section on Sheet C602 shows a top of bank elevation of 937.5. Please review and revise. This issue has been addressed satisfactorily. 21. The minimum freeboard elevationfor the detention area is 2-feet above the 100- year critical flood elevation. Please include in the construction plans proposed spot elevations and include/revise the details in Items 3 and 20 above to show this elevation. This issue has been addressed satisfactorily. 22. The invert elevations for Structures 1, 2, 18 and 19 are below the normal pool elevation of 864.0 for the detention area. Please review and revise as necessary. This issue has been addressed satisfactorily. 23. Sheet C301 shows a typical cross-section labeled "SECTION A-A H, with no reference to what this cross section represents. Please review and revise. This issue has been addressed satisfactorily. u o D U I ' U D U o U U U U [J o u u Opus Landmark al Meridian WooJpert, lnc. October J 2, 2005 Page 3 of4 c u u 24. There is a discrepancy with the rim elevations shown on Sheets C300 and C30J and the rim elevat ions provided on the 'Storm Drain Flow Tabulation Form" in the drainage calculations for Structures 2, 3, 4, 5, 6, 7, 8, 9, 1 J, 12 and 13. Please review and revise. This issue has been addressed satisfactorily. 25. Structures 16, 23,24. 25, 27, 30 and 32fail to meet minimum cover requirements. The cover requirements for these structures is where the invert elevation of the largest pipe diameter is less that the difference between the rim elevation and 2- feel plus the largest pipe diameter in fiet. Please review and revise. In reviewing the structures in question, Structure 27 is not constructible based on the given elevations and the diameter of pipe specified. Please review this structure and revise as necessary~ The balance of the structures in question do not meet tire City of Carmel storm design requirements for minimum constructability for cover; however, due to the constraints oflhe outlet elevation, this design is acceptable. It is recommended, but not a cond~tion for approvaL, that Class V pipe and flowablefill be used for these structures per the City of Carmel storm design requirements. u u u u D u Please include with your submittal, one (1) copy ofthe comments indicating the action taken or a written explanation for action not taken.
