SUMMARY REPORT GENERAL WATERSHED ANALYSIS CALZETTI SCHOOL , NXTH ANDOVER, MA. CALCULATION OF 10 YEAR AND 100 YEAR PRE AND POST PROJECT CONDITIONS E PREPARED FOR WILLIAM PRESSLEY & ASSOCIATES 423 COLUMBIA RD CAMBRIDGE, MA. BY : ENVIRCNMENTAL DESIGN & PLANNING, INC. 253 WASH INGZCN ST. BELMONT, MA. 02178 WILLIAM C. PISANO, P.E.- PRINCIPAL-IN-CHARGE FEBUARY 14, 1990 PART CNE : INTRODUCTION & CONCLUSIONS Figure 1 shows the analysis area encompassing rouahly 42 acres . This area was subdivided into 22 subcatchments for the purpose of utilizing the Soil Conservation Service TR-20 model implementation. Figure 2-A and 2-B depicts the catchments-. Table 1 presents summary hydrologic paraneters for the 22 catchments 11 Pre and post" modeling required a total of 49 and 62 modeling operations, respectively, to model the complex interaction of functions, ie computing runoff hdroaraphs, addina hydroaraphs and routing through storage elements. TR20 permits interaction of multiple catchments, storage areas diversions , multiple outlets , etc . The model is widely used in large scale urban drainaae catchment modeling , but lends itself also to smaller complicated watersheds havina multiple flaw directions . Figures 3 and 4 depict the "pre and post" loaic TR- 20 loa_is diarams necessary to model this problem. By inspection it can be seen that the problem is extremely complex. , It should be noted that the diversion option was used to model the interaction of the flaw patterns at the existing Farm Pcnd. The pond is bermed well above ground level The lower strean culvert and the inlet and outlet pipes in pond are at same elevations and have similar diameters When ditch spills it passes into a lea area and flaws to wetland "LL" at about elevation 224-. The pond is completely encircled with a protective berm preventing sheet flaw input. The analysis considered the 100 year and 10 year 24 hour rainfall events ( SCS Type III rainfall ) . The analysis is summarized in Figures 5-7 and in Tables 2 and 3. Figure 2 shows the 100 year pre/post hydrographs leavina the site through the existing sets of twin barrel culverts passing Lnder the Wolf Driveway. The post peak flaw condition is deliberately made less than the pre condition for expediency. Since the surface of the on-site land mass chances from pre to post condtions, an informative calculation is to sum the three hydrographs leaving the site for pre and post conditions. Figures 6 and 7 show the pre and post 100 year and 10 year summed hydrographs for the Wolf culvert, sheet flaw directly onto Abbott and the discharge from the upper wetland culvert. Tables 2 and 3 summarize important pre/post flow conditions at various locations on the site for the 100 and 10 year events respectively. The 100 year calculations indicate that for pre conditions all the on-site storage areas are slight and overtopping occurs ( with the possible exception of the Wolf culvert and the Farm Pcnd) -. On-site around elevation at Wolf cuvert is about 210+/ The existing storage behind the lower wetland road crossing and the two stream crossings are nealible. 2 Similar conclusions are reached for the pre 10 year event. However the upper wetland is not overtopped and normal flow culvert flow occurs. Under post conditions, additional onsite storage is generated in the lower wetland ( by pondino to hiaher elevation) and in a new proposed stormwater detention facility. This latter facility is laraer in size than for earlier represetations. It is intended that the storacre within the new detention pond weuld not tcp for either the 10 or 100 year event ( emergency bypass will still be provided)-. The new lower wetland crossing is designed to pass the 10 year storm without tor-pina , and permit some spill at the 100 year storm event r r , Estimated capacities at different depths of flaw within the rock ditch runninq parallel to Wolf driveway from the culvert crossincr down to Abbott Street is shown in Table 4-. Field measurements were made to ascertain dimensions. The invert profile generally is parallel with the ground fall down the driveway. By inspection of the ditch area , it appears that any flaw depth in excess of 18" would beqin to substantially cause erosion and damage to the existing trees along the driveway. By inspection of Tablas 2-4, there appears to be adecruate capacity to handle project pre and a post flows. However, it is recommended that more substantive rip rap protection at the driveway culvert outlet be provided as a aeneral precaution. Additionally, it is recommended that additional rip-rap protection be provided in the turning section near the intersection at Abbott Street Without such protection erosion on the face slope of Abbott Street may occur 3 PART TWO : TR20 ANALYSIS A. Data Preparation Table 5 depicts the SCS type III fractional distribution used to scale total rainfall per events into 24 hour hyetrearaph. Totals for 100 and 10 year events used are 6-.6 inch and 4.7 inches , respectively. Table 6 depicts the input data for existing conditions . Types of Operations, area ( sa. mile) composite CN values and times of concentration ( hr) are given along with operation controls, etc. Table 7 provides an operation key to the particular TR-20 functions useds in this analysis. Due to the smallness of the watershed and the relatively short length of the main system if spline, the TR20 "Reach" function was not used As a result the design will be slightly conservative. Table 8 presents storage & flaw rating curves develcped for the existing on-site culverted areas. Six such areas are used and the locations are ncted -. Storage was develcped from existing tOpo TOP The "Thysys " culvert routine was used to compute discharge for various headwater elevations. Table 9A-B shows a typical calculation and Figure 8 gives the stage rating curves for the two twin culverts sets crossina Wolf Road. Hydraulic flows at over-toppina conditions for the storage areas were not calculated , only estimated. B. Pre condition Results For the 100 year event Tables 10,11,and 12 depict the hydroaraphs of the three outlets from the site: a) Wolf Way_ culvert, sheet flow from subarea "S" onto Abbott and the upper wetland discharge ( subarea "U") , respectively-. Water surface elevations are also given for various hydroaraph points for the wetlands within subareas " 0 and U"-. Table 13A-B provides summary for all areas summed areas, and storage area outlets for the 100 year event. By inspection it can be seen that nearly all of the storage areas ( with the exception of Farm Pond and Wolf Road culvert ) substantially topped ( the elevations shown are only representative) -. Table 14A B presents similar results for the 10 year storm. The existing storage areas within the strewn section and the lower wetland crossina provide very little attenutation -. The upper wetland area does provide dampening of flows -. Table 15 presents the 10 year storm hydrograph and corresponding water elevations at the Wolf Way culvert entrance. W C. Wolf Way Channel Capacity Figure 9 depicts sketch of rock channel cross section parallel to Wolf driveway from outlet of culvert sets down to Ahbott Street. Tables 16A-B-C present typiial calculations for various assumed depths of flow within the channel section. D. Post Conditions The TR20 model approach for post conditions was as follows. First, all of the impacted areas ( building, pavement, grass, planters, replicated wetlands, etc) were noted for each subcatchment shown on Figure 2B . This impacted areas ( noted in Table 17 A ) were deducted from the Pre project catchments . A total area of 5-.31 acres of impact are noted. Next new catchments and functions were modeled and their catchment areas and characteristics are noted in part B of Table 17. The sum of the new areas obviously equals the sum of the deleted areas from the original set. The new areas discharge to the new detention pond, the lower wetland storage area , and the upper wetland Figure 4 depicts the operational logic for the post condition. Table 18 summarizes the revised post condition input operations to TR20-. Tables 19A-B present the storage and discharge characteristics for the seven storage areas. For storage area 4 ( lower wetland) it is intended to pond up to elevation 217.5. New storage volumes are indicated. Table 20A--B presents typical calculations ( using THYSYS ) for a new proposed twin 1511CMP culvert set at the road crossing. Figure 10 depicts the rating_ curve for the proposed culverts at this location. For storage area 5, the new stormwater detention pond ( G.45 acre-ft at spill) is proposed with a 3 cfs +/- vortex flan controller ( see Figure 11 for approximate curve) and emergency spill at elevation 213.50 ( +/-) -.- ' Spill discharge levels shown are representative and will be adjusted during final design. Tables 21A-B and Tables 22A-B present the 100 year post hydrogrpahs for the new storage pond and Wolf culvert outlets , respectively. Input flaws peaks are also sham. Note that tcpping does not occur at both locations. Table 23A-B summarizes peak flow conditions at all locations and provides peak water surface elevation for each storage area for the 100 year storm event. Note that the road crossing_ at lower wetland is just topped . S Tables 24A-B and Tables 25A-B present the 10 year post hydrocgrpahs for the new storage pond and Wolf culvert outlets respectively. Input flaws peaks are also shown. Table 26A-B summarizes peak flaw conditions at all locations and provides peak water surface elevation for each storage area for the 10 year storm event. Note that topping does not occur at new stormwater pond, the lower wetland area road corssina and the Wolf culvert. - , to ) '1 r AIM)K of � t , �- � "'`�,li (J/') `-� J r/� r• - ) �� ��L_ _ 1' ��J /�� �� ���ICJ L, ��0� n�// •n ,\\ �� � `\\\�� (_1�(."��J _�� •��� � �('� Oi�/ � (� ��',� 0 �--�� �> �� `-� �' — •���� � o���Z �i If to 1 5 i • ' S � � „ `. , .� � � _: ����- ��, -_ ICJ' \`• �'�J �� - = � - r � � .' 1h a �. .is-a�, .y �Yy_ (�Yu ak�,.✓ e M�..9^��ggY n.5.{2k( s iEaeze. ....n- a x-.
