Town of Princeton-DCC Bylaw TRUE Consulting Technical Appendix - 1.1 - January 2022
SECTION 1.0 INTRODUCTION AND OBJECTIVES
Development cost charges (DCCs) are not currently levied by the Town of Princeton (the Town). As such, The Town is proceeding with a process to adopt a new DCC bylaw. The objectives for the new DCC bylaw are DCC’s applicable to all catego ries of devel opment including non - residential, D CC’s for all infrastructure categories owned and operated by the Town and full compliance with applicable Provincial guidelines. This technical appendix is a supporting document to the Town’s new DCC Bylaw No . 1015,
2022. This technical appendix provides i nformation on all DCC capital proj ects and details the
calculation methodology for DCC’s for each infrastructure category. This technical appendix follows the recommendations of the Best Practices Guide (3rd edition, dated 2005) as closely as possible.
Town of Princeton-DCC Bylaw TRUE Consulting Technical Appendix - 2.1 - January 2022
SECTION 2.0 DEVELOPMENT COST CHARGE
BYLAW FORMAT
2.1 Time Frame
The Best Pr actices Guide (BPG) describes two options for program time frame that may be used as the basis for determining capital project requirements which then leads to the derivation of DCCs. One option is described as a build out approach where a capital plan is used to define all necessary projects to service dev elopment anticipated to occur to the full extent and level defined by the current Official Community Plan (OCP). For the Town, the build out approach to the derivat ion of DCCs represents the fol lowing difficulties and complications: uncertainty of assistance programs from senior levels of government for road, water supply and sanitary sewer capital projects. changes by senior government to the regulatory standards for water supply, wastewater treatment and disposal, etc. preparation of capital cost estimates for projects that may be constructed 15 to 25 years in the future is, at the best of times, extremely difficult. The second time frame option described as being acceptable in the BPG is the revolving program approach. The revolving program consists of on ly those capital projects which are necessary to service development that is expected to occur in a defined or specified time frame, i.e., a 5- or 10- year period. As co mpared to the build out approach, it is significantly more straightforward with the revolving program to derive a realistic design population for the DCC calculations. It is also more straightforward to accurately describe capital works requirements and cost estimates for a 5 -to-10-year design population than a 25 year or longer time horizon. Uncertainty f actors related to technology, and senior government policies and standards, become less of a concern with the shorter time horizon. In consultation wi th the Town, the revolving pro gram approach is the preferred option for the derivation of DCCs. A 10-year projection time frame has been utilized for the revolving program approach with population and development projections derived from various reputable sources.
2.2 DCC Levy Format
The Best Pr actices Guide recommends that DCC’s should be establ ished on a municipal -wide basis unless there is a significant disparity between those who pay and the benefiting users. A municipal-wide charge means that the same DCC rate is applied for a part icular lan d use
Town of Princeton-DCC Bylaw TRUE Consulting Technical Appendix - 2.2 - January 2022
throughout the municipality regardless of the specific location and benefiting area of a capital project. The BPG presents the following as potential advantages of the municipal-wide approach: the complexity and co sts of administration associated wit h numerous Sector area charges is eliminated. municipal-wide charges “keep it short and simple” and thereby reduces confusion. there is no inequity in development potential between different areas of the municipality. even in the Sector approach there is some “averaging” in the derivation of charges. Wherever practical, the BPG suggests that municipal-wide approaches be utilized. Consistent with the BPG, a municipal-wide format is used for the DCC Bylaw. All capital projects included in the DCC bylaw equally benefit from new development in all sectors of the Town.
2.3 Assist Factors
Section 933(2) of the Local Government Act states that the purpose of DCCs is to provide funds
to ‘ assist’ local government to provide and improve parks and construct i nfrastructure. Accordingly, there is a requirement for municipalities to provide an assist factor in the derivation of DCCs. The assist factor: may be set as low as 1%. generally, reflects Council’s desire to encourage development and is therefore largely a political decision. may be varied from time-to-time by Bylaw amendment to ensure that DCCs do not deter development. may vary by components, for example 5% for sewers, 10% for roads, 25% for parks, etc. With the technical appendi x, the BPG requires that the assist factor and resultant assistance amount be clearly shown. An assist factor of 1% has been used in this Technical Appendix. It should be noted that the assist factor is, for each infrastructure category, applied to the gro ss DCC recoverable amount before subtraction of the current DCC account balance. This m ethod of calculation is in accordance with guidance from the Ministry of Community, Sport and Cultural Development.

SECTION 3.0 DEVELOPMENT PROJECTIONS
3.1 Population Projections
Consistent with the revolving program approach described in Section 2.0, the DCC calculations are derived on the basis of a 10- year population projection. Historical population data from Statistics Canada for the Town is present ed in Table 3.1. The 5-year average growth between data sets has ranged from 1.8% to 3.8% between 2001 and 2016. In comparison, the Regional District of Okanagan-Similkameen (RDOS) saw the growth between data sets for the same time periods ranging from -3.3% to 3.7%, while for British Columbia it was 5.3% to 7.0% (see Table 3.2). The census population data was derived from the short-form Census as opposed to the long-form census, which i s collected from a 25% sample of the population. The RDOS Housing Needs Assessment Report (2021) and the Town of Princeton Housing Needs Report (2020) used the long-form census data which provides more housing related data, however, is less accurate in terms of population figures. In terms of annual aver age population growth rates between 2001 and 2016, the Town experienced an average growth rate of 0.56% annually over the 15- year period, as did RDOS, while the province saw a 1.26% increase in growth. When looking at annual average population growth rates over a 5-year period (2011 to 2016) one can see that the Town experienced a slightly higher growth rate of 0.76%, compared to RDOS at 0.56%, whereas the whole of British Columbia was 1.13%.

While BC Stats shows the Regional District with a relatively stable rate of growth between 2016- 2020, the sa me doesn’t hold true for Princeton which shows some notable swings in growth during the same period. This could be attributed to fluct uations in th e mining and forestry industry. Recognizing that there is no current DCC Bylaw in which to reference projected growth rates, nor are population projections included in the Official Community Plan (2008) , additional data should be considered to further assist in determining an appropriate gr owth rate for the Town . As such , projected growth rates from the Princeton Housing Needs Report (2020) and the RDOS Housing Assessment Report (2021) are included below.

The RDOS assessment shows a 4.7% projected 5-year average growth rate for the To wn between 2016-2021 and 3.4% between 2021-2026, as shown in Table 1.4 above. This results in an average annual growth rate 0.93% and 0.67% respectively during those periods. Whereas the Princeton housing report projects a 5 -year average growth rate of 2.9% for the same two periods, resulting in an average annual growth rate of 0.59%. To determine projected populations and development DCC-eligible projects, a conser vative growth rate of 0.72% has been used for population projections within the Town for the next 10 years, as show in Table 3.5 below.

3.1 Resulting Development Projections
3.1.1 Residential
From Section 2.0 , a 10 -year build out timeframe is used for t he DCC calculation. As noted earlier, in the absence of population projections in the current OCP, population projections were derived from Statistics Canada census profile data. The anticipated build out population to 2031 within the Town boundaries is est imated to be 3150 representing an increase in population of 218 between 2021-2031. As compar ed to the projected population of 2 ,932 (2021), the build out population of 3, 150 represents an increase of 218 over the 10-year build out period.
2016 Census popul ation distribution data indicates that the average household size is 2.0
people per unit. Recognizing that the average household size varies depending on the housing type, low density residential will be set at 2.1 persons per unit, medium density at 2.0 persons per unit and high densi ty at 1.5 persons per unit. Based on a review of the historica l household
Town of Princeton-DCC Bylaw TRUE Consulting Technical Appendix - 3.4 - January 2022
and dwelling characteristics (Stats Can), new residential development to the build out population of 218 is assumed to comprise: Low Density Residential 83% 86 units @ 2.1/unit = 180 Medium Density Residential 7% 8 units @ 2.0/unit = 16 High Density Residential 10% 15 units @ 1.5/unit = 22 Total 100% 109 units = 218
3.1.2 Non-Residential
The BPG requires development projections of non-residential land uses i ncluding commercial, industrial, and institutional. Typically, projections of non-residential land uses are based on an assessment of historical building permit data. For small munici palities such as P rinceton, building permit data can lead to erroneous projections recognizing: One or two permits fo r a large industri al or commercial building are better classified as anomalies rather than being indicative of the rate of new development. Lack of consistent reporting of building permits. Often building permits do not differentiate between new constructi on, renovations, or replacement. In the absence of building permits reports, l and utilization data included in the Town’s Princeton Housing Needs Rep ort (2020) was used to show exist ing split between commercial, industrial and institutional uses within the Town.
TABLE 3.6: NON-RESIDENTIAL LAND UTILIZATION
Non-Residential Use Based on Ha Based on Parcels Commercial 34% 41% Industrial 52% 50% Institutional 14% 9%
Non-residential la nd use development ratios developed from building permit data from other small Central Interior municipalities are summarized below: Clearwater 20,000 m2 / 1,000 population increase Sicamous 25,000 m2 / 1,000 population increase Oliver 27,200 m2 / 1,000 population increase Osoyoos 30,000 m2 / 1,000 population increase Taking into consideration the above information, an appropriate ratio to apply to non- residential land use in Princeton for DCC bylaw purposes is 25,000 m² per 1,000 population growth. Based

on a reasonable mix of commerci al, industrial and institutional uses, the estimated new non- residential development for a 3,150 build out population will comprise:

SECTION 4.0 WATER SUPPLY
4.1 New Infrastructure Requirements
In accordance wi th the various referenced infrastructure studies and in consultation with Town staff, the following water supply projects are planned to be constructed in the next 10 years.
4.1.1 Distribution Network
The wat er distribution network projects listed below ar e required to provide a higher level of service in the next 10 years to ac commodate 2,932 in existing population and 218 in new development. Therefore, DCCs should collect 218/3,150 (6.9%) of these project costs. Design Population 3,150 New Development (10 year) 218 Benefit to Population in DCC Horizon 6.9% Project W1: Brooks Booster Station Replacement The Brooks Booster Station is currently running at capacity. D uring summer months, both pumps in the booster station regularly run for twen ty hours per d ay each – with no standby capacity. Furthermore, the Brooks Booster pumps and electrical components are housed in a poorly accessible, below grade chamber which presents challenges due to confi ned space issues. Replacement of this booster station is neces sary to accommodate additional demands throughout pressure zone 770 as identified in the Town ’s Brooks Booster Station Replacement Predesign Report (June 2015). This project has an estimated cost of $760,000. Project W3: Industrial Area Watermain Upgrading The Town’s Water System Capacity Analysis (February 2012) includes a looped water main from the existing industrial area back to the Airfield Reservoir to address fire flow deficiencies in the area. Based on the conceptual alignment in the Water System Cap acity Analysis, approximately 1,400m of 300mm watermain will be installed. This project has an estimated cost of $980,000.
Town of Princeton-DCC Bylaw TRUE Consulting Technical Appendix - 4.2 - January 2022
4.1.2 Water Treatment & Storage
Project W2: New Well at Water Supply Well No. 4 Site The Town’s Water System Capacity Analysis (Febr uary 2012) noted that the current water supply wells (#1, 2, and 4) appear to have adequate capacity to sustain population growth to approximately 3,200 people. Recent analysis of this water supply indicates that the groundwater wells are experiencing capacity degradation issues and may not mee t demand requirements by 2023. Based on recommendations from the T own’s Groundwater Management Strategy (August 2007), a new well with a sustainable y ield of about 45 L /s has been proposed for the water system. Thi s additional capacity would provide service for an addit ional design population of about 1,500 based on a cu rrent per capita Maximum Day Demand (MDD) of about 2,600 l pcd as per the Town’s Water Conservation Plan (January 2020). Therefore, this water supply project would be expected to be adequate to a population projection of about 4, 500. Please note that this population projection does not account for a future decrease in well capacities. This project has an es timated cost of $762 ,000. 100% of the costs related to his project are to be collected from DCCs a s th is project has been initiated to serve the projected population growth. The project has a design population of 4,500 to accommodate future grow th of about 1,500 and the existing population of 2,932. DCC s should collect 218 /1,500 (14.5%) of this project cost. New Growth included in Design Population 1,500 New Development (10 year) 218 Benefit to Population in DCC Horizon 14.5%
4.2 Capital Cost Summary and DCC Calculation
The calculation for net amount recoverable by DCC funding for the wat er supply projects i s summarized in Table 4 .1. The calculation uses the benefit factors described in Section 4 .1 to determine the ‘Benefit to New Development’ for each projec t, the total of which is the DCC Recoverable Cost. Prior to calculating the result ing DCCs, the DCC Re coverable Cost is decreased by the Municipal Assist Factor (1%). There is no applicable grant funding for these projects to be subtracted from the DCC Rec overable Cost. Also, as the Town does not curren tly levy DCCs , existing DCC Reserves are not considered.

SECTION 5.0 SANITARY SEWER
5.1 New Infrastructure Requirem ents
In accordance with the various referenced infrastructure studies and in consultation with Town staff, the following sanitary sewer projects are planned to be constructed in the next 10 years. Project S1: Relining of Fenchurch Forcemain The Fenchurch lift station and the associated, older cast iron forcemain were installed in 1960 to pump most of the Town’s municipal wastewater from the downtown c ore to the wastewater treatment facility. A forcemain break occurred in the early 90’s which released untreat ed sewage into the Similkameen River. This break resulted in the Memorial Park wells (located immediately downstr eam of the forcemain river crossing) becoming contaminated. It i s understood that the Town was then forced to shut down the water supply at thi s location after members of the community experienced adverse health issues. Therefore, this forcemain break resulted in interruptions to water and sewer service for the communi ty and also negatively impacted the surrounding environment. Following this ev ent, the T own immediately began planning for the construction of a new forcemain from the Fenchurch lift station. This new forcemain (constructed o f high- density polyethylene) w as commissioned in 1996 and was m eant to act in parallel with the older forcemain during periods of peak usage. Unfortunately, public works rec ords indicate that this preferred operational set-up (i.e., parallel forcemains operating during periods of peak flow) was not acted upon and the older forcemain has been inactive since 1996. The existing lift station and HDPE forcemain are currently at capacity. The Town has also taken the following actions to determine whether the older cast iron forcemain c ould be brought back into service, thereby increasing the capacity of the system. CCTV inspection of the existing pipeline. Two sections of the cast iron forcemain were removed and sent to a materials laboratory to conduct a condition assessment Repair the sections of main that were removed and then conduct a pressure test. The results of t he above have indicated that the existing pipeline cannot be brou ght back into service. As such , it was recommende d that the Town proceed wit h a Cu red in Place Pipe (CIPP) liner installation if this option is found to be viable. Consideration of a different trenchless technology such as pipe bursting or slip- lining of a new pipe within existing cast iron forcemain may also be warranted.
Town of Princeton-DCC Bylaw TRUE Consulting Technical Appendix - 5.2 - January 2022
This project has an estimated cost of $725 ,000. 100% of the costs related to his project are to be collected from DCCs as this project will be initiated to serve the projected population growth. From the Town’s North Princeton Servicing Feasibility Study (July 2019) , this project has a design popul ation of 3,648 to accommodate future grow th of about 716 and the existing population of 2,932. DCCs should collect 218/716 (30.4%) of this project cost. New Growth included in Design Population 716 New Development (10 year) 218 Benefit to Population in DCC Horizon 30.4% Project S2: Culbertson Lift Station Replacement The Culbertson Lift Station is currently running at capacity and has been identified as a priority replacement project in the T own’s Asset Management Plan (June 2019). Furthermore, the Culbertson Lift Station submersible pumps are hou sed in a poorly accessible, below gr ade chamber with no lift out allowances . This confi guration presents significant operational challenges due to co nfined space issues. Replacement of this lift station is necess ary to accommodate additional demands throughout the collection area. This project has an estimated cost of $685,000. The project is required to provide a higher level of service in the next 1 0 years to accommodate 2,932 in existing population and 218 in new development. Therefore, DCCs should collect 218/3,150 (6.9%) of these project costs. Design Population 3,150 New Development (10 year) 218 Benefit to Population in DCC Horizon 6.9% Project S3: Sanitary Sewer Trunk Main Upgrading The existing trunk main to the North Princeton area is undersized and will limit service capacity in this area. Correction of these capacity issues is not a modest issue and would likely involve a general sewer collection system asset replacement program. A suggested strategy from the Town’ s North Princeton Servicing Feasibility Study (July 2019) and Sanitary Sewer Collection System Capacity Evaluation (December 2010 ) to allow development to proceed prior to correcti on of all deficient gravity sew er piping would be to replace three existing sections of gravity piping considered most deficient from a capaci ty perspective. These t hree sections of deficient sewer main ar e located on Riverside R oad, Poplar Street and Lime Street. This project has an overall estimated cost of $608,000. 100% of the costs related to t his project are to be collected from DCCs a s t his project has been initiated to serve the projected population growth. The project has a design population of 3,244 to accommodate future growth

This project involves replacement of the existing pumps with larger capacity ones and vari ous electrical syste m upgrades to both accommodate these upgrades and also ensure that the new electrical upgrades are housed in an explosion proof manner. Centrix Control Solutions has estimated cost of the cost of this project as $337,400 – although this cost does not include upgrading of the electrical service, trenching, backfilling, and concrete pads. With this in mind this project has an overall estimated cost of $411,000. 100% of the costs related to his project are to be collected from DCCs as this project will be initiated to serve the projected population growth. From the Town’ s North Princeton Servicing Feasibility Study (July 2019) this project has a design population of 3,648 to accommodate future growth of about 716 and the existing population of 2,932. DCCs should collect 218/716 (30.4%) of this project cost. New Growth included in Design Population 716 New Development (10 year) 218 Benefit to Population in DCC Horizon 30.4%
5.2 Capital Cost Summary and DCC Calculation
The calculation for net amount recoverable by DCC funding for the sanitary sewer projects is summarized in Table 5 .1. The calculation uses the benefit factors described in Section 5 .1 to determine the ‘Benefit to New Development’ for each project, the total of which is the DCC Recoverable Cost. Prior to calculating the resulti ng DCCs, the DCC Recoverable C ost is decreased by the Municipal Assist Factor (1%). There is no applicable grant funding for these projects to b e subtracted from the DCC Recoverable Cost. Also, as the Town does not currently l evy DCCs, existing DCC Reserves are not considered.

SECTION 6.0 MUNICIPAL ROADS
6.1 Project Descriptions
Municipal road projects considered necessary t o the DCC population of 3,150 have been identified on the basis of the Town’s Roadworks Capital Plan (February 2011), input and comment from Town administration staff, and “Transportation” objectives of the OCP listed following. Create an accessible environment where people of all ages, using a variety of transportation modes (including walking, cycl ing, motorized scooters, wheelchairs), can move with ease. Promote the use of multiple modes of alternative transportation ( i.e., pedestrians, bicycles, scooters, and wheelchairs) within the community. Consider the needs of pedestrians and cyclists using the road network and where possible provide opportunities to enhance safety of these users. Municipal road projects for the purpose of DCC calculation are illustrated in Appendix A and are summarized by objectives as follows: Collector Road Surfacing o Project R4: Laurie Currie Way Surfacing (Highway 5A to Princeton-Summerland Road) $858,000
Local Road Surfacing/Upgrading o Project R2: Jacobson Road Reconstruction (Old Merritt Highway to Watermain R/W). Presently, the road is not constructed to an ur ban standard and is in poor condition, with a gravel surface, no sidewalks, drainage facilities, nor street lighting. The Town has identified this road as the init ial phase of a future key community access route, consistent with the OCP. It is expected that new development would be responsible for the second phase of this project. $897,000
Local Road Upgrading to provide Sidew alks Linkages between Neighbourhoods . These two roads have been identified by the To wn as key neighborhood linkages w hich presently do not include facilities for pedestrians or bicycles. As such these roads would be widened to include sidewalks complete with adequate drainage facilities. o Project R1: Corina Avenue Widening (School to Lapworth) $740,000 o Project R3: Granby Way Widening (Barr to Stout) $260,000

Utilizing this approach, the Best Practices Guide provides the fol lowing peak afternoon trip generation criteria for DCC apportionment by land use. The guide values have been reduced by 50% for non-residential land uses on the basis that the lower values are more representative of commercial and industrial uses in small municipalities in the central BC Interior area. low density residential 1.02/unit medium density residential 0.66/unit high density residential 0.62/unit commercial 0.007/m² of gross floor area industrial 0.0022/m² of gross floor area institutional 0.009/m² of gross floor area Applying these trip generation criteria to estimated new development as presented in Section 3.0 results in the following trip end totals by land use category.

SECTION 7.0 PARKS
7.1 Project Descripti ons
The Town of Princeton has historically required devel opers to contribute 5.0% of the predevelopment appraised land val ue in lieu of dedication of parkland. Furter details are in the Town’s OCP and the Parks and Recreation Strategic Plan (November 2013). The Town intends to continue this requirement therefore parkland acquisition is not a component of the Parks DCC. Consistent with the pedestrian access objectives as described here in Section 6.0 and the Parks and Trails in Secti on 4.1.7 of the OCP, two trail construction projects as illustrated in Appendix A and described following are planned. • Construction of a pat hway meant to connect the Swan Lake trail system to the Airport trail system. The trail length is approximately 700m (Project P1). • Construction of a pathway meant to connect the Jacobson Road area to the Airport trail system. The trail length is approximately 500m (Project P2). In addition to the above trail projects, construction of a public washroom facility within the Town boundary is planned (Project P3). This project location is currently planned in the general area of the dog park near the Trans Canada Trail, although this location is yet to be confirmed. Cost estimates for all three parks projects are contained in Appendix B.
7.2 DCC Calculations
Capital cost estimates for the t hree parks DCC projects are presented in Table 7 .1. For purposes of calculating t he DCC recoverable cost, the parks projects are assumed to be of general benefit. The percentage apporti oned to new development is the ratio of new development (218 population) to the horizon population (3,150) which is 6.9%.
