This will allow for sufficient lengths to rover the inlet with twelve (1 2) inches beyond they inlet on both ends. 3.0 construction Sequence 3.1 General 31.1. Install the GutterBuddyr"I in front of the curb inlet opening. Each end Of the GutterBuddyTIO should overlap the curb inlet approximately 12". 3.1.2 The Guttel-Buddy"I should be cleaned if a visual inspection shows silt and debris build Lip around the GutterBuddy `11, 3.1.5 To remove the GutterBucld)P, lift out of the opening. 3.1,4 The GutterBuddr is reusable. Once the construction project is complete and it is no longer deeded for sediment control, remove, clean and store out of the sunlight until needed on the next project, 3.1.5 Ponding is likely if sediment is not removed regularly. Inspection of GutterBuddy'm should be on a regular basis and immediately after major raid events. 4.0 Basis of Payment 4.1 The payment for any G€.ltterBuddyT11 used during the construction is to be included in the bid of the overall erosion and sediment control plan and priced by the linear foot.

WATERINIQUANTITY STORMWATER NARRATIVE CHANNEL PROTECTION THE CHANNEL PROTECTION REQUIREMENTS FOR POI -11 ARE BEING SATISFIED BY RELEASING THE POST DEVELOPED 1 -YEAR STORMWATER RUNOFF AT A RATE LESS THAN THE ALLOWABLE RATE CALCULATED USING THE ENERGY BALANCE EQUATION PER SECTION 9VAC25-870-66 - B - 3a. OF THE VIRGINIA STORMWATER MANAGEMENT PROGRAM. THE DRAINAGE AREAS AND ASSOCIATED MAXIMUM ALLOWABLE FLOW RATES ARE SHOWN IN THEENERGY BALANCE CALCULATION ON THIS SHEET AND THE STORMWATER OUTFALL TABLE ON THIS SHEET. IN ORDER TO RELEASE THE POST DEVELOPED 1 -YEAR STORMWATER RUNOFF AT THE RATE SHOWN, A STORMWATER MANAGEMENT SYSTEM HAS BEEN DESIGNED THAT UTILIZES A SERIES OF BMPS, WHICH INCLUDES A WET POND (POND 11) , AND ULTIMATELY RELEASED AS SHEET FLOW TO CONSERVED OPEN SPACE THROUGH A LEVEL SPREADER LOCATED AT THE OUTFALL FOR POIA 1.

IN ORDER TO RELEASE THE POST DEVELOPED 1 -YEAR STORMWATER RUNOFF AT THE RATE SHOWN, A STORMWATER MANAGEMENT SYSTEM UTILIZES A SERIES OF BMPS WHICH INCLUDE A WET POND AND A LEVEL SPREADER THAT RELEASES THE RUNOFF AS SHEET FLOW TO CONSERVED OPEN SPACE. SINCE THE IMPROVEMENTS PROPOSED IN PHASE I OF THE ROAD IMPROVEMENT PLANAR ARE WITHIN THE DRAINAGE RO MENT S AREAS CONTRIBUTING TO POi'S 10 AND 11, AND HAVE BEEN MODELED IN THE ABOVE MENTIONED CALCULATIONS, IT IS THE OPINION OF THE ENGINEER THAT CHANNEL PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI'S 10 AND 11 AND THAT NO FURTHER ANALYSIS IS REQUIRED FOR THE PHASE 1 IMPROVEMENTS. FLOOD PROTECTION FLOOD PROTECTION REQUIREMENTS FOR POI -11 ARE BEING BY MET BY SATISFYING THE REQUIREMENTS SET IN SECTION 9VAC25-870-66 - C -1 AND 9VAC25-870-66 - C -3c. THE 10 -YEAR 24 HOUR STORMWATER RUNOFF RELEASED FROM THE POND 11 IS CONVEYED IN A PROPOSED PIPE NETWORK WHICH HAS BEEN DESIGNED TO SAFELY CONVEY THE RUNOFF WITHIN THE SYSTEM AND IS DISCHARGED THROUGH OUTLET PROTECTION INTO AN EXISTING NATURAL CHANNEL ON SITE. CALCULATIONS FOR THE CAPACITY OF THE PROPOSED OUTFALL PIPE NETWORK CAN BE FOUND ON SHEET C-907. IN ADDITION THE EXISTING CHANNEL HAS BEEN ANALYZED AND FOUND TO ADEQUATELY CONTAIN THE 10 -YEAR 24 HOUR RUNOFF TO THE POINT WHERE THE RUNOFF REACHES A MAPPED FLOODPLAIN. CALCULATIONS AND CHANNEL CROSS SECTIONS FOR THIS CHANNEL CAN BE FOUND ON SHEET C-907. SINCE BOTH THE PIPE AND EXISTING CHANNEL ARE SHOWN AS ADEQUATE, IT IS THE OPINION OF THE ENGINEER THAT FLOOD PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI -11 AND NO FURTHER ANALYSIS IS REQUIRED. FLOOD PROTECTION REQUIREMENTS FOR POI -10 ARE BEING BY MET BY SATISFYING THE REQUIREMENTS SET IN SECTION 9VAC25-870-66 - C -1 AND 9VAC25-870-66 - C -3c. THE 10 -YEAR 24 HOUR STORMWATER RUNOFF RELEASED FROM THE POND 10 IS CONVEYED IN A PROPOSED PIPE NETWORK WHICH HAS BEEN DESIGNED TO SAFELY CONVEY THE RUNOFF WITHIN THE SYSTEM AND IS DISCHARGED THROUGH OUTLET PROTECTION INTO AN EXISTING NATURAL CHANNEL ON SITE. THE EXISTING CHANNEL HAS BEEN ANALYZED AND FOUND TO ADEQUATELY CONTAIN THE 10 -YEAR 24 HOUR RUNOFF TO THE POINT WHERE THE RUNOFF REACHES A MAPPED FLOODPLAIN. CALCULATIONS AND CHANNEL CROSS SECTIONS FOR THIS CHANNEL CAN BE FOUND ON SHEET C-906. SINCE THE EXISTING CHANNEL HAS BEEN FOUND TO BE ADEQUATE, IT IS THE OPINION OF THE ENGINEER THAT FLOOD PROTECTION REQUIREMENTS HAVE BEEN MET FOR POI -10 AND NO FURTHER ANALYSIS IS REQUIRED. ADEQUATE OUTFALL NARRATIVE AT THE POINT WHERE THE RUNOFF REACHES THE RIVER, THE CONTRIBUTING FLOW FROM THE SITE IS LESS THAN I% OF THE TOTAL FLOW IN THE RIVER AND NO FURTHER ANALYSIS IS REQUIRED. ADDITIONALLY, AFTER BEING RELEASED IAS SHEET FLOW THE RUNOFF FROM BOTH POI - 10 AND POI - 11 WILL EVENTUALLY REENTER EXISTING NATURAL CHANNELS THAT OUITFALL INTO THE RIVANNA RIVER. SINCE THE RELEASE FROM BOTH POI - 10 AND P01-11 IS LESS THAN WHAT IS ALLOWED BASED ON THE ENERGY BALANCE EQUATION (SEE ENERGY BALANCE CALCULATIONS ON THIS SHEET), AND THE POST DEVELOPED FLO Vti WILL BE ADEQUATELY CONVEYED INTO THE EXISTING CONVEYANCE CHANNELS THAT ARE IN A MAPPED FLOODPLAIN AIND HAVE THE CAPACITY TO SAFELY CONVEY THE 10 -YEAR RUNOFF TO THE RIVANNA RIVER, IT IS THE OPINION OF THE ENGINEER THAT THE ADEQUATE OUTFALL REQUIREMENT HAVE BEEN MET FOR BOTH POI - 10 AND POI - 11. WATER QUANTITY CONCLUSION IT IS THE OPINION OF THE ENGINEER THAT BECAUSE THE WATER QUALITY, CHANNEL PROTECTION, FLOOD PROTECTION, AND ADEQUATE OUTFALL REQUIREMENTS HAVE ALL BEEN SATISFIED, THE SITE IS IN COMPLIANCE AFTER THE PHASE I SECTION OF THE ROAD IMPROVEMENT PLANS HAVE BEEN COMPLETED AND NO FURTHER ANALYSIS OR CALCULATIONS ARE REQUIRED.

In general, consider watering every days for first month, and then weekly during the remainder of the first growing season (April - October), depending ort rainfall, 9.3. Inspections and Ongoing Maintenance Tasks Maintenance of a wet pond is driven by annual inspections that evaluate tine condition and performance of the pond, including tite following: • Measure sediment accumulation levels in the: forebay. • Monitor the growth of wetland plants, trees and shrubs planted, Record the species and their approximate coverage, and dote the {presence: of any invasive plant species. • Inspect the condition of stormwa,Ler inlets to the pond for material damage, erosion or undercutting. • Inspect the batiks of upstream anddownstream channels for evidence of sloughing, annual burrows, boggy areas, woody growth, Or gully erosion that may Lundern,ine embankment integrity. • Inspect the pond outfall channel for erosion, undercutting, rip -rip displacement, woody growth,y t,tc. • Inspect the condition of the princi{pal spillway and riser for evidence awf spelling, joint failure, leakage, corrosion, etc. • Inspect the condition of all trash racks, reverse -sloped pipes, or flashboard risers for evidence ofclogging, leakage, debris accumulation, etc. • Inspect maintenance access to ensure it is tree of woody vegetation, acrd check to see whether valves, manholes and locks cart be opened and operated:. • Inspect internal and external side slopes of the pond for evidence of +sparse vegetative cover, erosion, or slumping, and make needed repairs immediately. Based on inspection results, specific maintenance tasks will be triggered, Example maintenance inspection checklists for Wet Pontis can be accessed in ,Appendix C of C"hapter 9 of the Virginia Stor-ranvaierllltana,gemeat Mandbook (20 10) or at the: CWP websiteat: ll ttotllwww.cwo.oraJResource LibrarvIControllinct Runoff and Dhseharaeslsm.htm l (scroll to TooW Plan Review, BMP Construction, and Maintenalmce Checklists) For a more detailed maintenance inspection checklist, see Appendix B in CVP )ta cuter Pond and k€'`ed and Afahtttmancc Guidebook (2004). Maintenance is needed so stormwater ,ponds continue to operate as diesigned on a long. -term basis. Wet ponds normally have fewer routine maintenance requirements than other stormwater control measures. Stortll at r pond nianuctiance activities vary regarding the level of effort and expertise required to perform them. Routine stormwater pond maintenanrce, such as mowin and p q p 1 g removing debris and trash, is needed several times each year (See Table 14.6). More significant maintenance (e,g., removing accumulated sediment) is needed less frequently but requires more skilled labor and special equipment. Ins ection and repair of critical structural features ti embankments and risers) needs to be performed by a qualified professional (e.g., a structural engineer) who has experience in the construction, inspection, and repair of these, features. The maintenance plan should clearly outline how vegetation in the pond and its buffer will be managed or harvested in the future. Periodic mowing of the stormwater: buffer is only required along maintenance rights-of-way and the embankment, The remaining buffer can be managed as a ineadow (mowing every other year) or forest. The maintenance ,:plan should schedule a shoreline cleanup at least once a year to remove trash and floatables. Table 94.6. Typical Wet Pond Maintenance Tasks and ,Frequency Maintenance Items Frequency • Mowing — twice a year COMMENT BY Quarterly or after major storms • Remove debris and blockages (71 inch of rainfall) • Repair undercut ended, and bare call areas p 2 • Mowing Twice a year • Shoreline cleanup to remove trash, debris and 3 floatables. FOR APPROVAL • A full maintenance inspection Annually • Open up the riser to access and test the valves • Repair broken mechanical components, if needed One icor—during a time r the 9 • Pond puffer and aquatic bench reinforcement plantings second year following construction • Forebay Sediment Removal Every 5 to 7 years • Repair pipes, the riser and spillway, as needed From 5 to 25 years 9.4. Sediment Removal Frequent sediment removal from (lie f6febay is essential to maintain the function and performance of a wet pond. Maintenance plans should schedule cleanouts approximately proximately ever 5 p €� 1 1 1 y to 7 years, or when inspections indicate that 50%D uffiprebay sediment storage capacity has been on-site filled. The designer should also check to see whether removed sedirncllts can be spoiled cn Slte or roust be, hauled away. Sediments excavated from wet ,ponds are not usually considered toxic or hazardous. They can be safety disposed of by either land application or land. tilling. Sediment testingmay be needed prior to sediment disposal if the retrofit serves a. hots pot land use. y l l 1 SECTION 10: COMMUNITY & ENVIRONMENTAL CONC:I ENS Wet ponds can generate the following community and environmental concerns that need to be addressed during; design. Aesthetic Issitc:s: Many re idenli feet that wet ponds are in attractive landscape feature, promote a greater sense of corm -nu City and are an attractive habitat for fish and wildlife, Designers should mute that these benefits are often diminished where wet ponds are tinder -sized or have small contributing drainage areas.. Existing Wetlands. 1A ,.vet pond should clever be constructed within an existing natural wetland. Discharges from a wet pond into an .existing natural wetland should be nlinirnized to prevent pollution damage and changes to its hydroperiod. E.vistiarg Forests. Construction of a wet pond may involve extensive clearing of existing forest cover. Designers can expect a great deal of neighborhood opposition if they do not make a concerted effort to save mature trees during {fond design and construction. �� FF P4rh P4 1 � PTJ z o° ow C>Q ZLU L'U 0 H=w Gni ut�za, 5) 1 �m ¢x1—QO¢ XUQF-ca0 =o ii W 1� w � U w O 0 z o0 Q �C alLx �ZQ "''un,o C� � ZU >--U, Z �w �;� wXw Q oW � w m 2> X — — a �G ¢coMLuzz> om > w 0 ° w w , CQ z =xm`==�E ° � z Lu O w¢ O O w 5 (0 0= menZU �w sr . > w �0P4 2--- M�W Y a p O Q ¢`a (14>_ l � w wzZQ�>-x �> Zg2EYYNn. o0 w(D -TX w w� ¢w°Ow Q F 0 >->- ow �3:I-)�:3: d w° w w Lu= 5 Z m Z Z Z 2 z _ Cl) o REVISIONS REV DATE COMMENT BY 1 6/11/18 COUNTY COMMENTS ADB 2 914118 COUNTY COMMENTS RTY 3 9/27/18 FOR APPROVAL RTY KNOW WHAT'S BELOW ALWAYS CALL 811 BEFORE YOU DIG It's fast.
