There will be a cast aluminum dimensional letters of the school name and address number near the front entry. See revised A100 for exact location. 2. C100 – COVER PAGE a. A Structure Data Table shall be provided in the plan set. At a minimum, the structure data shall include the following information: structure number reference, upstream structure number, downstream structure number, top casting elevation, upstream pipe elevation, downstream pipe elevation, pipe length, pipe material, pipe size, type of structure and detail reference to type of structure and any notes related to the structure. Structure data table is on Sheet C500. b. Detail sheets identifying pertinent details related to the stormwater management system. All Manholes and Inlets must be pre-stamped with an appropriate message per Hamilton County Standard Detail Drawings per 501.03; Manhole/inlet inside sizing shall be according to the Hamilton County Standard Detail Drawings per 501.03; Bedding and haunching for all reinforced concrete pipe installations per 501.04 (Carmel Standard Drawings); Debris Guard designed in accordance with Hamilton County Surveyor’s Office Standard Detail D-12 shall be provided for any pipe or opening per 302.06.6 Detail D-12 was already on Sheet C601 series (details). Details added per comment: D-16, D-23, CT-1, CT-4 & CT-5 on new Sheet C607. c. Ponding and overflow path throughout the development resulting from a 100-year storm event or from a flood route of an internal detention pond or off-site development or watershed, calculated based on all contributing drainage area, on-site and off-site, in their proposed or reasonably anticipated land use and with the storm pipe system assumed completely plugged, shall be determined, clearly shown as hatched area on the plans, and a minimum width of 30 feet along the centerline of the overflow path contained in permanent drainage easements and shall remain within the limits of the development (shall not encroach onto adjacent properties). A statement shall be added to the secondary plat that would refer the viewer to the construction plans to see the entire extent of overflow path as hatched areas. No fences or landscaping or Center Road Elementary School PZ19060003 SU 2 any other above grade improvements can be constructed within the easement areas that may impede the free flow of stormwater. These areas shall be designated Added hatched 30 foot-wide permanent drainage easement for 100-yr flood route out of basin. It is understood that a statement needs to be added to the Secondary Plat which refers the viewer to construction plans to see overflow path as hatched area. 3. C101 – DEMO PLAN (NORTH) a. Please show any necessary storm water controls on the demolition sheets or revise this note to state that controls shown on C401 must be installed prior to any disturbance. Added note that C401 controls must be installed prior to disturbance. 4. C200 – OVERALL SITE PLAN a. Also, will the path be extended to the southern property line of this parcel? The path along Clay Center Road will run fully across the School’s property and extend to the relocated entrance on the neighboring property. The path is not being extended across the neighbor’s parcel itself. b. Please consider moving some of the racks to the other side of the entrance so people on bikes don't have to cross the entrance walk to park their bikes. The building façade was “stepped back” to allow room to nest the bikes in their proposed location. The available room north of the Main Entrance does not adequately accommodate the bike racks. The Petitioner respectfully prefers to not move the bike racks. c. Please consider providing space for a potential bike safety course to be installed. We have reviewed the course requirements needed to host a bike safety course and will provide a layout plan to the School. The School can utilize this plan to tape-off or chalk-off the course whenever it is needed. The petitioner prefers not to provide any permanent striping for a bike safety course. d. The City of Carmel bicycle parking standards requires that bike racks be installed with 30" between each other and be a minimum of 24" from walls or obstructions. Please refer to section 5.29 of the City's UDO to view the spacing standards to ensure that the racks will be installed in compliance with these requirements. Please include the spacing standards on the detail page along with the rack detail. Please see L502 for Detail. e. Provide a sidewalk connection around this area to allow for full pedestrian connectivity. The pedestrian sidewalk connection safely links Domino Drive to the sidewalks on the north end of the Bus Lot. See L100 series plans. To honor the safety guidelines endorsed by the School Board, pathways cannot cross drives dedicated to service and bus vehicles. They must link to the safe sidewalk network. A sidewalk connection for after-hours athletic parking is provided to ensure they can utilize the primary parking lot. f. Please provide a direct connection to/from the baseball fields to/from this path. See L100 series for a Multi-use path the Petitioner has asked the design team to reflect as an alternate bid. g. Please show/label the electric, gas, HVAC, and/or water meters on the site plan, and also show how they will be screened from view and/or camouflaged. Showed electric, gas, HVAC & water meter call-outs. The outdoor mechanical yard will be fenced from view see A103 for mechanical yard layout. Center Road Elementary School PZ19060003 SU 3 h. Please show/label the drive aisle widths, as well as a typical parking space size. See UDO section 5.28. Added to L100 Site Materials overview plan. i. Please label the bicycle parking area or add a Legend to the plan. Added to L100 Site Materials overview plan. j. Please label the building square footage. See L100-L106 Site Materials series. k. Please verify that the parking lot is curbed. The parking lot is curbed. See L100-L106 Site Materials sheets. l. Please address the concerns about noise. Please also refer to the City Code Noise Regulations and maximum allowed dB. The little league baseball fields will not be equipped with a PA or sound system. Carmel Dad’s club currently operates under a ‘curfew’ at its other facilities terminating events at 10 PM Sunday- Thursday and 11 PM Friday-Saturday. m. The Planning Dept. would like to have further discussions with you about the extension of Domino Drive for vehicular access to/from the site. Even if it just ends up being emergency access for Police & Fire. The Petitioner respectfully prefers not to extend Domino Drive into the site due to safety concerns of uncontrolled public through-traffic within the school parcel. The School coordinated with the Fire Department regarding emergency needs and were told a third access is unnecessary. Likewise, it is our understanding that the School and City have received strong objections to the road extension from adjacent neighbors and the developer of Jackson’s Grant. n. Is there any right-of-way to be dedicated? Yes, proposed ROW is indicated on revised plans. o. Upon further examination, north of the north proposed entrance: it was not possible to accomplish the grading of the roadway as was previously shown (100’ straight piece then taper). It caused a vertical conflict of steeper than 3:1 from edge of roadway to existing walk / trail that we are connecting to. 5. C301 – GRADING PLAN (NORTH) a. Per Section 104.02 of the Storm Water Technical Standards, the FFE of the building must be 1' above the adjacent roadway. Please revise. First, we understand the nature and intent of 104.02. The intent is to make sure that a building is not built on a low elevation right next to a roadway such that water runs off of the road and to the building and may flood it. It makes sense that if a building is right next to a roadway and built at least 1 foot higher that this would likely protect the building from flooding. Our proposed building is not adjacent to Clay Center Road. Adjacent would imply: abutting, alongside, touching, joining, having or sharing a common side. None of this is the case here. Between Clay Center Road and the proposed building we have over 290 feet of improvements planned: a sidewalk, a roadway, a parking lot, a sidewalk, a roadway, and then one more sidewalk before we get to the building. The roadway or roadways which are truly adjacent to the proposed building and are therefore applicable per 104.02 are the adjacent roadways directly in front of and directly behind the building. Center Road Elementary School PZ19060003 SU 4 Escape paths have been designed for flood protection: FF= 868.50 for the school building. In front of the building, the highest roadway pavement elevation is 867.18 (1.32 feet lower than FF). The 100-yr overland flow path is designed as such: If the storm water pipe system were to become ineffective, the escape point on the pavement in front of the building is 866.36 near the southwest building edge. From there, the next escape point is a top-of-curb point 867.00 where the roadway / driveway makes a 90 degree turn. The next escape point is a sidewalk point of 866.66. From there, to the other edge of the same sidewalk at 866.46, to 866. 45 pavement elevation to 865.83 pavement elevation (south of loading dock, south pavement edge), to 865.75 top of curb final escape point prior to entering a swale and being gone around the softball field swale toward the detention pond. The highest point in this escape path is 867.00 (1.50 feet lower than FF), so even if water got to 6 inches deep there, it would still be at least 1.00 feet lower than FF of building. Behind the building, the highest roadway pavement elevation is 867.20 (1.30 feet lower than FF): a high point in the turn-around cul-de-sac. The 100-yr overland flow path is designed as such: if the storm water pipe system were to become ineffective, the water runs away from the building and jumps the top of curb at elevation 865.50. In front of the playgrounds there would be a pond which would escape south along the curb line across elevation 865.90 thence again escaping the top of curb at elevation 865.50 and then it would drain toward the retention pond. For this reason, we have met the intent and nature of 104.02. Besides that, the Clay Center Road elevation is as high as 871.7 near the north entrance. 1.00 feet above this would be 872.7, which is 4.2 feet higher than we are proposing. Regarding overflow design, or 100-yr emergency overland flow path, “FR arrow” symbols have been added to Sheets C301 to C304 to show the storm water relief pattern. b. Please provide a swale to more efficiently convey drainage to the east. We have a tree protection zone there, but even so, our proposed grading does create the desired swale. Flow arrows have been added to illustrate the channelized flow pattern. c. the grading plan shall include the delineation of all proposed land disturbing activities, including off-site activities that will provide services to the project site. Please revise. Sheet limits have been adjusted to show all proposed grading limits. d. the grading plan shall include the definition of minimum flood protection grade in accordance with this manual. Definition added to Sheets C301 to C304. Regarding Flood Protection Grade (FPG), this has been determined and labeled for each building and each grading sheet. For the main school building, the FPG is 868.00. If the storm water drainage system were to become completely ineffective, the highest escape point that the 100-year overland flow route would have to overtake is top of curb point 867.00 (south-most point in southeast corner of 90- degree turn in “drop off zone road”). Such a flow would not exceed 6 inches (half a foot) in depth, so the highest elevation that this flow has been engineered to be is 867.50 in the 100-year (and probably 500-year in this case) storm event. This allows still a minimum of 1.00 feet (probably more) of freeboard in this extreme event which almost certainly will never happen. Center Road Elementary School PZ19060003 SU 5 For the building centered amongst the softball fields, the FPG is 865.80 (2.00 below FF). In no case can water get to this elevation in a 500-year event. For the small maintenance building, the FPG is 864.30. The escape point is a ground point of 864.10 headed east from the inlet nearest this building. Overflow might get to 0.20 feet deep, hitting a 100-year elevation of 864.30. This allows still a minimum of 1.00 feet of freeboard in this extreme event which will probably never happen. e. the grading plan shall include drainage arrows shall be indicated for all surface drainage, swales and on each side of every break in swale slopes. Flow arrows have been added to indicate flow patterns. f. All buildings shall have a minimum flood protection grade shown See response to Part d. g. Please show and label the location of the tree preservation fencing and its location along the woodlands on all grading sheets. Please confirm that it matches up with the tree protection and removal plan sheet LD -100. Tree preservation fence call-out has been added to C301 to C304. Tree preservation fence has been adjusted to be outside of grading zones. Locations agree with Sheet LD100. h. Add subsurface drain to swale. Added subsurface drain to northernmost swale. 6. C302 - GRADING PLAN (SOUTH) a. the grading plan shall include the delineation of all proposed land disturbing activities, including off-site activities that will provide services to the project site. Please revise. Sheet limits have been adjusted to show all proposed grading limits. b. the grading plan shall include the definition of minimum flood protection grade in accordance with this manual. Definition added to Sheets C301 to C304. c. the grading plan shall include drainage arrows shall be indicated for all surface drainage, swales and on each side of every break in swale slopes. Regarding Flood Protection Grade (FPG), this has been determined and labeled for each building and each grading sheet. d. All buildings shall have a minimum flood protection grade shown Regarding Flood Protection Grade (FPG), this has been determined and labeled for each building and each grading sheet. 7. C303 – GRADING PLAN (BASEBALL) a. There are several spot shots labeled as "???". Please provide the elevations for these shots. Spot elevations corrected. 8. C304 – GRADING PLAN (POND) a. It appears that the pond will spill over at a different location than where the emergency spillway is shown. Please show the rip rap where the flood routing shows it spilling over. Center Road Elementary School PZ19060003 SU 6 We don’t see what you are talking about. Emergency spillway is to be completely protected by stone revetment and the plans show this. We believe that the rip-rap is where the emergency spillway is. See 100-year flood routing arrows. b. This would include the normal pool, 100-year elevation, top of bank, etc. All critical pond elevations should be called out now. c. It appears the existing drainage patterns drain to the southeast corner of the property. Is it possible to relocate the spillway to this corner of the pond? Emergency spillway is not advised to be relocated to southeast corner of pond dam. If water were to ever leave the pond via the emergency spillway, we have done our best to choose a gently-sloped path which should minimize the possibility to cause erosion failure to the dam. d. It appears the project is relying on the swale in the adjacent neighborhood. Please provide a swale on the property between the pond and the property line. We have provided an emergency spillway and overflow swale on our property. It is detailed with spot grades and contours on Sheet C304 including an enlarged 1”=30’ plan view. e. the grading plan shall include the emergency flood routing path(s) and their invert elevations from detention facilities to the receiving system. See above comment response. f. the grading plan shall include the location, size, and dimensions of features such as permanent retention or detention facilities, including natural or constructed wetlands, used for the purpose of stormwater management, to include new ponds or basins to be built, critical pond elevations, pond bottom elevation, top bank elevation, spillway location and elevation, and transverse slopes of dry detention areas. All such requested information should be available now. g. the grading plan shall include a drainage summary, which summarizes the basic conditions of the drainage design, including site acreage, off-site/upstream acreage, allowable release rates, post- developed 10-year, and 100-year flows leaving the site, volume of detention required, volume of detention provided, and any release rate. Drainage summary has been added to Sheet C304. 9. C401 – SWPP PLAN a. It appears that silt fence is proposed along the center line of Clay Center Road. Is this accurate? The silt fence has been relocated b. Please show this on the plans and provide a detail. Temporary sediment basin added, temporary rock check dam added and detail provided as needed. 10. C402 – SWPP PLAN (CONST) a. If this is to remain, please move the silt fence so it will not be trenched through the roots and provided tree protection behind the silt fence. The silt fence is now shown in front of the tree protection fencing. b. Please show the Storm Lines on this Plan. The storm lines and structures are now shown on this plan. c. Show a temporary rock check dam around the detention basin outlet structure. The check dam has been added. Center Road Elementary School PZ19060003 SU 7 d. Will the tree line along the south property line be preserved? Yes, it is now shown as being preserved. 11. C403 – SWPP PLAN (FINAL) a. Please show the BMP easement over the BMP's as well as an access easement connecting the BMPE to the City's right-of-way. The BMP access easements have been added. b. Please note here that the plantings proposed below normal pool will need to be plugs rather than seed. A note specifying plugs on the detention banks has been added along with a note to See Plan on L401 and Details on L410. c. Please show the second water quality unit that will be installed per this note. We are unable to locate it on this sheet. The note has been corrected to describe only one Aqua-Swirl BMP unit. d. Please show the location of the signage and provide a detail for these signs. “Do not Mow” signage is shown on Sheet C402 and detailed on Sheet C405. e. Please only show the proposed topography on this sheet. Complete. f. Please show all storm lines on this sheet. Complete. 12. C406 – SWPP INFORMATION a. Please place this narrative in the City's format rather than the States. I have uploaded the document "City of Carmel SWPPP Requirements" to the correspondence folder. This document outlines our format. Complete. 13. C502 – UTILITY PLAN (SOUTH) a. Install valves Valves added per mark-up. b. move hydrant valve to this location Moved hydrant valve location. c. there was prior discussion of a connection to the existing water main in the neighborhood for a loop is this not an option now? There has been a decision to not connect to Domino Drive water main. It would cost a lot of money for little if any gain, and could possibly overtax the existing residential neighborhood system, in particular in the event of a fire at the school. d. "Please see my comments below: i. Is the gas meter going to be inside the outdoor mechanical yard or on the outside wall? Gas meter is to be inside fenced outdoor mechanical yard. ii. I would like the service line to be ran on the southside of the driveway, out of the pavement. Gas line shifted southward as much as we think is possible to meet the request. iii. Do you know when construction will start? Construction will commence in September of 2019. Center Road Elementary School PZ19060003 SU 8 iv.

Please change to red oak as it seems to do better. Per email confirmation with the Urban Forester, white oak is acceptable. 26. LD100 – TREE PROTECTION AND REMOVAL PLAN a. can the fencing from area 5 connect with area 4 to area 3? just fence off everything to the east of the woodlands edge. the green hatching would stay the same but the fencing location would be easier to string in one line and connect the areas. Areas 3-5 connected; See LD100 27. LITHONIA DSX0 a. Are these Light fixture designs proposed for the parking lot only, or are they also proposed for the ball fields? These fixtures are for the parking lot lighting only. 28. STORM REPORT a. The pre-development calculations shall include a pre-development watershed map, including the drainage area designation corresponding to the designations in the drainage calculations, the area in acres for each drainage area and any off-site drainage areas that need to be accommodated by the system, including the fully developed right-of-way per the City of Carmel Thoroughfare Plan, the post developed curve numbers for each drainage area. Existing (pre-this-development) calculations and watershed map have been added which illustrate existing flows. b. There two Appendixes are reversed in the manual. I saw one sheet in there twice and once it was rotated 180 degrees. Hopefully that has not happened this time. c. "For sites where the pre-developed area has more than one (1) outlet, the release rate should be computed based on pre-developed discharge to each outlet point. The computed release rate for each outlet point shall not be exceeded at the respective outlet point even if the post developed conditions would involve a different arrangement of outlet points. Please review, as it appears from review of the existing topography, this site has multiple outlet points." Center Road Elementary School PZ19060003 SU 10 Project has been analyzed in both existing conditions and proposed conditions with its applicable multiple outfall points as determined by the engineer. System models have been included in the report with applicable diagrams and drainage area maps which have corresponding sub-area labels. Calculated detention effect has been illustrated in the conclusion of the Narrative Section of the Storm Water Report. These calculations prove effective detention in both of two possible ways: 1. The 0.1 cfs / acre for a 10-year storm and the 0.3 cfs / acre for a 100-year storm limits. The limits are met. 2. Comparison of proposed outfall point flows to existing outfall point flows for both the 10-year storm and 100-year storm. Reduction of every point flow is achieved. 29. O/M REPORT a. Please relabel this throughout the O&M manual. O&M Report revised to say Wet Pond with Native Banks. b. Please add a section for maintenance of the native plantings and mowing guidelines. Added; see O&M manual.
