4 STRASBURG CREEK FLOOD CONTROL ENVIRONMENTAL ASSESSMENT, PEDESTRIAN CROSSING ADDENDUM Purpse f Addendum April 22, Purpse f Addendum The Strasburg Creek Fld Cntrl (Schedule B ) Class Envirnmental Assessment (EA) was cmpleted in May 2014 fr the City f Kitchener t assess the preferred means t incrprate the required fld cntrls int the Strasburg Creek system (Strasburg Creek Fld Cntrl Class Envirnmental Assessment Envirnmental Study Reprt, Stantec Cnsulting Ltd., May 2014). The primary fld cntrl feature assciated with the Hurn Rad crssing has already been cnstructed and n changes t this cmpnent are being cntemplated. The riginal study als cnsidered ptential changes t the cnfiguratin f the stream crssing f Fischer-Hallman Rad at the upstream limits f the study area. At this lcatin, there were tw criteria: 1. The crssing is required t cnvey Reginal Strm flws acrss the radway with a maximum upstream fldplain elevatin f m (based n previus fldplain assessments) 2. The City desired a pedestrian crssing at this lcatin as part f the City Trails Master Plan, and the EA assessed whether this trail crssing culd be incrprated as part f the stream cnveyance system Fllwing cmpletin f the Fld Cntrl Class EA, the Regin f Waterl began wrk n an Envirnmental Assessment fr the upgrades t Fischer-Hallman Rad thrugh the same study area. New infrmatin frm this prcess is nw available, including preliminary rad prfile and crss sectins, and a mre detailed cnsideratin f the existing watermain. It has been determined that the watermain is the primary supply fr the Hurn Village Cmmunity, and as such cannt be mved r temprarily shut dwn t facilitate cnstructin. The pedestrian crssing at Fischer-Hallman Rad and Strasburg Creek was identified in the Fld Cntrl EA as a belw-grade crssing (in assciatin with the stream cnveyance system), which wuld require the relcatin f the watermain. With these details nw available regarding the prpsed Fischer-Hallman Rad imprvements, the City has requested that additinal wrk be cmpleted t ensure that the mst apprpriate frm f pedestrian crssing is cnsidered, given that the pedestrian crssing can be independent f the stream cnveyance system. It was determined that additinal examinatin f ptential frms f pedestrian crssing shuld be cmpleted thrugh an Addendum t the Class EA. The prpsed prblem statement fr this addendum is: Determine the mst apprpriate means f prviding a safe pedestrian crssing f Fischer- Hallman Rad t link future urban develpment areas t the west with the Hurn Natural Area and trail system t the east. The crssing must nt cmprmise the Strasburg Creek flw cnveyance capacity, the City f Kitchener Multi-use Pathways and Trails Master Plan, integrate with the Fischer-Hallman Rad Class EA and must minimize impacts t existing infrastructure, including the 450 mm diameter watermain. lm v:\01603\active\ \design\reprt\addendum\rpt_d22-15_lm_scfcea_addendum_v5.dcx 1.1

5 STRASBURG CREEK FLOOD CONTROL ENVIRONMENTAL ASSESSMENT, PEDESTRIAN CROSSING ADDENDUM Backgrund April 22, Backgrund The Strasburg Creek watershed is lcated in the suthwest part f the City f Kitchener. The Main/Middle branch f Strasburg Creek riginates nrthwest f the intersectin f Fischer- Hallman Rad and Bleams Rad and flws generally sutheast thrugh a well-defined, wellvegetated valley crssing Hurn Rad apprximately 1 km west f Strasburg Rad. The Strasburg Creek Master Watershed Plan (SCMWP) was cmpleted by Paragn Engineering Ltd. (nw Stantec Cnsulting Ltd.) and Eclgistics Ltd. in As part f the study, hydrlgic mdelling fr the watershed was cmpleted based n assumed develpment patterns and recmmended a series f majr n-line fld cntrl structures t minimize the ptential fr dwnstream flding and ersin impacts. The Grand River Cnservatin Authrity (GRCA) and the City f Kitchener apprved the SCMWP shrtly after its cmpletin. One f these n-line fld cntrl structures was recmmended fr cnstructin just upstream f the Main Branch s crssing f Hurn Rad. The functin f the prpsed structure was t cntrl utflws fr infrequent strm events t minimize the ptential fr negative dwnstream flding impacts due t the develpment f the upstream catchments. As a result f the SCMWP, the City identified the necessity f preparing a Schedule B Class Envirnmental Assessment (EA) t examine alternatives fr the prpsed means f prviding sufficient cntrls upstream f Hurn Rad. The Class EA fld cntrl recmmendatins have been implemented in cnjunctin with the recnstructin f Hurn Rad and are nw currently in place and functinal. While the primary fcus f the Fld Cntrl EA was t ensure that the flw cntrl targets are achieved dwnstream f Hurn Rad, further evaluatin was als cmpleted at the Fischer- Hallman Rad crssing upstream f Hurn Rad t address fldplain issues with existing and future develpment, and accmmdate a pedestrian crssing. The study made recmmendatins as t the preferred pedestrian crssing cnfiguratin in cnjunctin with the stream cnveyance system. As the Regin f Waterl prceeded with additinal wrk n Fischer-Hallman Rad upgrades, including rad prfiles, crss sectins and watermain details the City has requested that additinal wrk be cmpleted t ensure that the mst apprpriate frm f pedestrian crssing is cnsidered, given that the pedestrian crssing can be independent f the stream cnveyance system. Based n the riginal EA, it was determined that additinal examinatin f ptential frms f pedestrian crssing shuld be cmpleted thrugh an Addendum t the Class EA. 2.1 PREVIOUS REPORTS This Class EA Addendum uses infrmatin frm several ther cmplimentary prjects and City dcuments including the fllwing: lm v:\01603\active\ \design\reprt\addendum\rpt_d22-15_lm_scfcea_addendum_v5.dcx 2.1

6 STRASBURG CREEK FLOOD CONTROL ENVIRONMENTAL ASSESSMENT, PEDESTRIAN CROSSING ADDENDUM Backgrund April 22, 2015 Hurn Natural Area Phase 1 Implementatin Plan (2007). An implementatin plan was prepared fr the City f Kitchener that identified the intended areas f imprvements within the Hurn Natural Area (HNA). These included trails, bardwalks, interpretatin areas and cnnectin pints t the HNA and the surrunding cmmunity. Phase 1 identified a cnnectin and trail alng Strasburg Creek and a cnnectin acrss Fischer-Hallman Rad. Alder Creek Watershed Study and Upper Strasburg Creek Subwatershed Plan Update (2008). The tw watersheds (Alder Creek and Strasburg Creek) are lcated beside each ther and have recgnized inter-relatinships between grundwater systems and surface water systems. This study prvided water quality and water quantity cntrls as well as land use management t prtect vulnerable areas. Upper Strasburg Creek Class EA (Fischer-Hallman Rad crssing) (2008). This study was intended t reslve fldplain and majr flw cntrl issues under existing cnditins, upstream f Fischer-Hallman Rad by determining which mdificatins may be required t the Strasburg Creek Culvert at Fischer-Hallman Rad t reduce the Reginal Strm fld elevatin t 335 m. A Reginal Strm elevatin f 335 m is required t prevent flding f the existing prperties and structures upstream f Fischer-Hallman Rad. The recmmend slutin was the mdificatin f the existing Fischer-Hallman culvert t cnvey Reginal Strm flws under the radway s that the water level was less than 335 m. This EA acknwledged that the Strasburg Creek Fld Cntrl EA culd supersede the Upper Strasburg Creek EA relating t fld cntrl requirements fr the Reginal Strm. Hurn Rad Imprvements Class EA (2010). Hurn Rad thrugh the study area was in need f recnstructin and upgrade due t infrastructure deficiencies related t pavement cnditin, radway traffic capacity, strm drainage, hrizntal and vertical rad gemetrics and vehicle and pedestrian safety. The primary bjective f the Hurn Rad Class EA Study was t identify the preferred alternative fr upgrading the rad crridr t a fully urban cnditin and imprving the verall servicing cnditins f the rad. These imprvements were subsequently implemented as utlined in the Hurn Rad Re-cnstructin final engineering plans (2012) Suthwest Urban Area Study, Strmwater Management Strategy (2011). This study assessed and recmmended strmwater management criteria fr the Rsenberg Area upstream f Fischer-Hallman Rad City f Kitchener Urban Design Manual, Sectin 4.8 Fischer Hallman Rad Crridr (2012). The Urban Design Manual has a clearly defined visin and guidelines fr the Fischer-Hallman Rad Crridr. This crridr will functin as the central spine fr the Rsenberg Cmmunity that will supprt transit thrugh the develpment f cmmercial, residential and ffice develpment thrughut the crridr. The entire streetscape is t create a sense f chesin with distinguishable urban and natural character areas within it. The Strasburg Creek area has been identified as a natural streetscape area within the manual. A midlm v:\01603\active\ \design\reprt\addendum\rpt_d22-15_lm_scfcea_addendum_v5.dcx 2.2

City f Kitchener Multiuse Pathways and Trails Master Plan (2012). The Master Plan is a cmprehensive City wide plan fr the lng term implementatin f multi-use pathways and trails. Trail types, surfacing, lcatins, wayfinding and general details are identified within this master plan. A trail was identified t crss Fischer-Hallman Rad at Strasburg Creek. This trail wuld prvide a cnnectin t the Hurn Natural Area and the future develpment alng the Fischer-Hallman Crridr. The trail was identified as a desired secndary trail cnnectin (Type 2). Type 2 trails are cnsidered variable surface with 3 seasn maintenance. These trails wuld be 3.0 m wide and culd be cnstructed with a cmpacted granular surface (e.g., stne dust) but cnsideratin culd be given t cnstructing the trails using asphalt r cncrete if site cnditins warrant the change t surface treatment. Strasburg Creek Fld Cntrl EA Envirnmental Study Reprt (2014). Previus studies had cncluded that several prperties were susceptible t flding, and the recmmended measures were t implement fld cntrl structures n Strasburg Creek. The primary bjective f the Strasburg Creek Fld Cntrl EA was t identify the preferred alternative t prvide the required fld prtectin (per the SCMWP) fr fld vulnerable prperties dwnstream f Hurn Rad. The recmmended fld cntrl structures have been cnstructed. The study als cnsidered ptential cnfiguratins fr a belw-grade crssing at the upstream limit f the study area (Fischer-Hallman Rad). It was anticipated that these features wuld be implemented in cnjunctin with Fischer-Hallman Rad imprvements, and therefre they have nt yet been cnstructed lm v:\01603\active\ \design\reprt\addendum\rpt_d22-15_lm_scfcea_addendum_v5.dcx 2.3

21 STRASBURG CREEK FLOOD CONTROL ENVIRONMENTAL ASSESSMENT, PEDESTRIAN CROSSING ADDENDUM Evaluatin f Alternatives April 22, Evaluatin f Alternatives The apprach t the evaluatin f alternatives has been cnsistent with that used in the riginal Class EA study. Thrughut the Addendum prcess, the varius alternatives were reviewed and discussed by the Prject Team and agency representatives. Each alternative was assessed using the evaluatin criteria and with a measure (scre) assigned t each. The measure is based n the individual criteria being scred with the highest pssible scre f 10 fr the best slutin. A scre f 5 was assigned fr slutins that met sme f the established measure fr the criteria and a scre f 1 was assigned t nn-cnfrming r least desirable slutins. Each sectin was ttaled and then averaged t prvide a ttal fr a best pssible scre f 50. Each categry has been weighted equally thrugh this assessment. Table 2 prvides the evaluatin matrix fr the alternatives. Table 3 is a summary f the evaluatin ratinale fr each criterin and each alternative. 4.1 PREFERRED ALTERNATIVE Thrugh the evaluatin prcess there was ne clear alternative that was the preferred ptin, Alternative #4, Optin A: At Creek. Mid-blck crssing near the Strasburg Creek culvert as per the Trails Master Plan. A pedestrian refuge island will be required fr the safe crssing f Fischer- Hallman Rad. Trails will tie int the infrmal trail cnnectins within the HNA which will allw fr future trail cnnectins t be implemented utside f the fldplain. Signage will be implemented t meet the current City and Reginal trail crssing and apprach signage. Refer t Figures 6 and 7. This alternative met the majrity f measures set fr each criterin and achieved 48.3 ut f a pssible 50. The fllwing is a summary f the key elements that established this alternative as the preferred. Natural Envirnment This alternative prvided the best balance f prtectin f envirnmental features, prtectin fr species at risk and prvides a direct cnnectin t the HNA that fits with the Master Plan and the Phase 1 implementatin Plan. Ecnmic Envirnment This alternative prvided the lwest capital cst and lwest lng term maintenance csts. Technical Envirnment The trail within this alterative can be easily implemented, as it nly requires the cnstructin f a trail and signage. There are limited requirements fr permits r impediments t the implementatin f the trail. This alternative prvides the smallest ftprint and minimizes the impact t the fldplain. lm v:\01603\active\ \design\reprt\addendum\rpt_d22-15_lm_scfcea_addendum_v5.dcx 4.1

In additin t the fld cntrl feature, the riginal study als cnsidered ptential belw grade pedestrian crssing cnfiguratins that crssed Fischer-Hallman Rad at the upstream limits f the study area. Fllwing cmpletin f the Fld Cntrl Class EA, the Regin f Waterl began wrk n an Envirnmental Assessment fr the upgrades t Fischer-Hallman Rad thrugh the same study area. New infrmatin frm this prcess is nw available, including preliminary rad prfile and crss sectins, and a mre detailed cnsideratin f the existing watermain. It has recently been determined that the watermain is the primary supply fr the Hurn Village Cmmunity, and as such cannt be mved r temprarily shut dwn t facilitate cnstructin. The pedestrian crssing at Fischer-Hallman Rad and Strasburg Creek was identified in the Fld Cntrl EA as a belw-grade crssing (in assciatin with the stream cnveyance system), which wuld require the relcatin f the watermain. With the prpsed Fischer-Hallman Rad imprvement details nw available, the City requested that additinal wrk be cmpleted t cnfirm that the mst apprpriate frm f pedestrian crssing is cnsidered. This additinal wrk tk the frm f an Addendum t the Class EA. The prpsed prblem statement fr this addendum is: Determine the mst apprpriate means f prviding a safe pedestrian crssing f Fischer-Hallman Rad t link future urban develpment areas t the west with the Hurn Natural Area and trail system t the east. The crssing must nt cmprmise the Strasburg Creek flw cnveyance capacity, the City f Kitchener Multi-use Pathways and Trails Master Plan, integrate with the Fischer-Hallman Rad Class EA and must minimize impacts t existing infrastructure, including the 450 mm diameter watermain.

31 NOTICE OF STUDY COMPLETION CLASS ENVIRONMENTAL ASSESSMENT ADDENDUM STRASBURG CREEK FLOOD CONTROL STUDY FISCHER-HALLMAN ROAD PEDESTRIAN CROSSING The Study In May 2014, the City f Kitchener cmpleted a Schedule B Class Envirnmental Assessment (EA) Study t examine fld cntrl ptins fr Strasburg Creek, between Hurn Rad and Fischer-Hallman Rad in the City f Kitchener and Regin f Waterl. The Strasburg Creek watershed is lcated in the suthwest part f the City f Kitchener. The Main, r Middle, branch f Strasburg Creek riginates nrthwest f the intersectin f Fischer-Hallman Rad and Bleams Rad and flws generally sutheast, crssing Hurn Rad apprximately 1 km west f Strasburg Rad. The Strasburg Creek Master Watershed Plan recmmended, amng ther things, a fld cntrl structure just upstream f Hurn Rad t minimize the ptential fr dwnstream flding and ersin impacts. The purpse f the riginal Class EA Study was t evaluate the apprpriate lcatin and cnfiguratin f the fld cntrl measures. A secnd cmpnent f this study als cnsidered the ptential fr a pedestrian crssing at Fischer- Hallman Rad. It was anticipated that a pedestrian crssing wuld be prvided at this lcatin t link the City trail system and culd be cnstructed in cnjunctin with the stream crssing. The preferred pedestrian crssing alternative frm this study was a belw grade pedestrian culvert (apprximately 4 m x 4 m x 45 m lng that wuld als cnvey water during extreme strm events). Additinal details n the surrunding areas have becme available fllwing the cmpletin f the riginal Class EA Study, and the City has elected t review the Fischer- Hallman Rad pedestrian crssing cmpnent t ensure that the mst apprpriate frm f crssing is cnsidered (e.g., abve grade, at grade and belw grade).

Apprximately 100 m f additinal trail length required t bring trail up t rad elevatin. Challenges include pedestrian safety (culd be addressed by a signalized crssing). Cmments/discussin: The Fischer-Hallman Rad imprvements likely t include (EA nt yet cmplete) a full raised median, rundabuts at Bleams Rad and Rsenburg Way, and a multi-use trail n bth sides f the rad. Shw nrth and suth branches f the trail n the west side f Fischer- Hallman Rad t match trail plans.

37 January 29, 2015 Steering Cmmittee Meeting Strasburg Creek Fld Cntrl EA Pedestrian Crssing Addendum Page 5 f 8 Item: Offset trail lcatins n either side f Fischer-Hallman Rad t discurage crssing utside f trail lcatins. Actin: Challenges include an indirect and lengthy trail cnnectin, and there may be safety cncerns since pedestrians are directed t crss at a rundabut. At Grade Crssing (Optin C At Rsenburg Way): Similar t Optin B, but trail crsses at Rsenburg Way, which deviates frm the Master Plan and requires an additinal 550 m f trail. Ptential fr alternate trail alignment suth f the prpsed develpment. Challenges include an indirect and lengthy trail cnnectin, and there may be safety cncerns since pedestrians are directed t crss at a rundabut. Cmments/discussin: Primary trail actually lcated further suth at the Hydr crridr and wuld like t discurage traffic thrugh the Hurn Natural Area. The Regin will nly cnsider a cntrlled crssing if it is mre than 200 m frm an existing pedestrian crssing/refuge and if use warrants. Abve Grade Crssing: Trail lcatin wuld cnfrm t Master Plan, but wuld be required t be a minimum 5 m high t accmmdate truck traffic, which wuld require mre than 100 m f ramps n bth sides f the rad t make the crssing accessible (5% grade). Challenges include the length f ramps required, and that the ramps will have t be lcated utside f the right-f-way. Cmments/discussin: Ownership and maintenance (bth structural and peratinal) f the structure wuld require further discussin between the City and Regin. D Nthing: The D Nthing alternative wuld mean that there is n crssing at this lcatin and wuld require an adjustment t the Master Plan fr cnsistency. lm v:\01603\active\ \design\crrespndence\minutes\min_a29-15_lm_strasburg_ck_addendum.dcx
