May 2025

FOREWORD

Flooding is a problem that until now has become an issue that must be solved in Bima City, so there needs to be special handling from various parties, both from the government and the community. Flooding is not a mild problem and occurs every rainy season arrives. The flood came without knowing the place and who inhabited the place. Flooding can occur in residential areas, rice fields, roads, fields, ponds, and even in urban areas. Flood disasters cannot be avoided, but they can minimize their impact by tackling potential flooding.

kegiatan pengendalian banjir di Kota Bima adalah dengan melakukan pembangunan kolam ret e nsi di Amahami di K elurahan Dara serta kolam retensi Taman Ria di K elurahan Monggonao, Kota Bima.
In its solution , the flood problem cannot be done only partially, but as a whole from the smallest problem point to the largest with the solution and control of the flood problem is carried out in the stem which is intact from upstream to downstream. Basically, flood control is an activity of planning, implementing work, exploitation, and maintaining rivers with efforts to repair and regulate river stems in the form of s i stem river network, river normalization, embankment strengthening, pond retention or drainage creation to reduce the risk of potential flooding. The plan for the creation of a retention pond is part of flood control activities in Bima City. One of the plans for flood control activities in Bima City is to build a ret e nsi pond in Amahami in Dara village and a Taman Ria retention pond in Monggonao village, Bima City. In solvingtheflood problem, the flood problem cannot be done only partially, but as a whole from the smallest to the largest problem point with the solution and control of the flood problem is carried out in a complete stem from upstream to downstream. Basically, flood control is an activity of planning, carrying out work, exploitation and maintenance of riverswith efforts to repair and regulateriver stem in the form of river network stem stems, river normalization, embankment strengthening, retention ponds or making drainage to reduce the risk of potential flooding. The plan forthe creation of this retention pond is part of flood control activities in Bima City. One of the plans for flood control activities in Bima City is to build a ret ensi pond in Amahami in Dara villageand a Taman Ria retention pond in Monggonao village, Bima City.

Every business and/or activity that has an important impact on the environment must have an Environmental Document. Therefore, as the initiator's commitment to environmentally sound development, this retention pond construction activity is complemented by an Environmental Document prepared with reference to Government Regulation of the Republic of Indonesia Number 22 of 2021 concerning the Implementation of Environmental Protection and Management, every activity that has an important or non-important impact on the environment must have approval milieu.

CHAPTER 1. INTRODUCTION

Background

Flooding is a natural disaster problem that must be immediately handled by various parties, both the government and the community. High rainfall and decreased river capacity can trigger flood disasters. In addition, river siltation, drainage and other factors are environmental damage caused by forest clearing activities and land conversion that can cause flooding downstream or in urban areas.

Flood control in Bima City is carried out in an effort to prevent the occurrence of larger floods and to increase the resilience of the people of Bima City to flood vulnerability. The activities that will be carried out in this case are the management of Bima City through the construction of the Amahami Retention Pond located in Dara Village, West Rasanae District, and the Taman Ria Retention Pond in Monggonao Village, Mpunda District, Bima City. In order for flood control efforts to prevent or reduce environmental and social risks, environmental and social management documents are needed as a guideline in minimizing negative environmental and social impacts due to the development of flood control infrastructure.

.

Some of the main gaps identified are the completeness of the details of project activities, the analysis of project alternatives that include technological considerations, and the environmental and social impact assessment of each alternative, the assessment and handling of associated facilities, the presentation of baseline data, and the handling of impacts that have not been previously identified (such as sediment handling, discovery of cultural heritage, gender-based violence, K3 risks, and community safety). Therefore, this UKL-UPL Supplement Document is prepared to complement the UKL-UPL document and add information related to the handling of the gap by referring to the NUFReP Environmental and Social Management Framework (ESMF), the NUFReP Stakeholder Engagement Framework (SEF), and the Land Acquisition and Resettlement Policy Framework (Land Acquisition and Resettlement Policy Framework/LARPF) NUFReP. The UKL-UPL Supplement Document, which has contained environmental and social provisions of the Government of Indonesia and the World Bank, will be the main reference for BBWS Nusa Tenggara I and contractors in implementing environmental and social management in flood control activities through the construction of the Taman Ria Retention Pond and the Amahami Retention Pond in Bima City.

Legal Framework

The policies and regulations that apply in Indonesia at the time of the preparation of the UKL-UPL Supplement Document underline the things that are guidelines for managing environmental and social impacts related to the activities to be carried out. The relevant Government of Indonesia policies categorized according to the World Bank's Environmental and Social Standards (ESS) are available in the table below.

Table 1.1 National Regulation on Environmental and Social Management

Environmental and social management in primary drainage rehabilitation/repair/strengthening activities also refers to the World Bank's Environmental and Social Framework (ESF) and the World Bank's Environment, Health and Safety (EHS) Guideline. This includes the environmental and social management framework document that has been compiled in the NUFReP Project, which in turn serves as further guidelines for activities that will use World Bank funding through the NUFReP Project, namely:

Environmental and Social Management Framework (ESMF) for NUFReP Projects;

Land Acquisition and Resettlement Policy Framework (LARPF) for NUFReP Projects;

Stakeholder Engagement Framework (SEF) for the NUFReP Project.

CHAPTER 2. DESCRIPTION OF THE ACTIVITY PLAN

2.1 Name, Location, and Scale of Activity

2.1.1. Construction of the Amahami Retention Pond

Administratively, the development plan for the Amahami Retention Pond in Bima City is located in Dara Village, West Rasanae District, Bima City, West Nusa Tenggara Province.

Boundaries in the village administration for the plan for the construction of the Amanami Retention Pond:

The north is bordered by Paruga Village;

To the east it is bordered by Sambinae Village;

The south is bordered by the Dara Village City Park;

The west is bordered by the Supermarket, Teluk Bima.

The existing conditions at the proposed location of the Amahami Retention Pond currently havefive existing ponds (Ponds A, B, C, D, E) as shown in Figure 2.1. In the plan for the Amahami Retention Pond activity, work will only be carried out on Pools A, B, and C. The three ponds are on land owned by the Bima City Government which is not functional. Pond A and Pond B are empty land whose condition will be waterlogged if it rainswhile Pond C is a swampy land surrounded by mangroves. Pond D and Pond E are not included in the planning of the Amahami Retention Pond because they are land owned by residents.

Retention Ponds A and B are concrete constructions while Retention Pond C is maintained and only normalizedThrough retention pond flood control activities, these three ponds will be connected to each other through a box culvert (Pond A is connected to Pond B, Pond B is connected to Pond C, Pond C is connected to the sea). This can be seen in the retention pool flow scheme in Figure 2.2.

Figure 2. 2 Amahami Retention Pool Flow Scheme

, dengan kedalaman pengerukan material ± 3 sd 4 m dari permukaan tanah. 

The current condition of the Amahami Retention Pond has an area of 7,187 m² or 0.7 Ha and an existing storage capacity of 10,066.75 m³, with the existing area and volume of each pond as follows:

Pool A, area 3548 m² and volume 5124.25 m³

Pool B, area 2334 m² and volume 2082.75 m³

Pool C, area 1305 m² and volume 2859.75 m³

It is planned that later with the earthworks in Ponds A, B, and C, the retention pond reservoir will increase to the following:

.

Retention Pool Plan B

.

Retention Pool Plan C

.

The activity plan of the Amahami Retention Pond generally consists of the repair of drainage channels, the construction of the retention pond, the normalization of the dredging of the retention pond, the installation of the pump system, and the landscape of the retention pond with details can be seen in Table 2.1.

Table 2. 1Scale of Activity Plan at the Amahami Retention Pond

The following are the details of the work that will be carried out on the Amanami Retention Pond:

Drainage Channel Repair

Based on the current condition of the existing channel with dimensions of 1 m wide and 1 m high, it has a discharge capacity of 1.17 m³/s. For the flood during the Q5 repetition of5.24 m³/s, it was still not enough to accommodate the surface runoff discharge, resulting in an overflow of 4.07 m³/s. Therefore, the channel capacity is optimized by maximizing the dimensions to be 1 m wide and 1.5 m high as per the design of the Amahami Primary Drainage with a discharge capacity of 2.08 m³/s. However, this design still overflows to the Q5's discharge of 3.16 m³/s. So that surface runoff in Dara Village needs other alternatives to handling flood inundation, one of which is in the form of retention ponds.

Construction Kolam A & B

.

Normalization/Dredging of Pool C

Pond C already functions as a water body and ecosystem so that no physical construction activities are carried out here, but to increase the storage capacity of the retention pond is carried out by normalization/dredging. Between Pool B and Pool C will be connected by a culvert in the form of a Box Culvert and then flowed towards the sea.

Pump System Installation

A drainage system with a pump is needed when the pool capacity has reached the maximum limit but there is a backflood so a pump is needed to reduce the pool reservoir. The number of pumps needed is as many as 3pieces with the capacity of each pump is 866 ltr/s.

Nature Based Solution (NBS) Concept

In the Amanami Retention Pond Landscape, there are Nature Based Solution (NBS) activities. In this work there is the planting of 30 trees where the type of tree planted is not recommended for productive trees but trees that benefit from shade for green open spaces such as kersen, ketapang kencana, kiara umbrella, red shoots, and banyans. In addition, it is also considered that the type of plant is not liked by the biota that spreads diseases such as mosquitoes, such as lemongrass, lavender, etc.

Technical Design of Amahami Retention Pond

.Permasalahan utama yang terjadi di Kelurahan Dara merupakan belum adanya jalur pembuangan drainase akibat dari elevasi Kelurahan Dara yang lebih rendah dari sepadan Sungai Padolo sehingga sistem outlet dari drainase di Kelurahan Dara masih belum optimal. Akibat dari hal tersebut limpasan permukaan pada Kelurahan Dara tertidur Jalan Sultan Muhammad Salahuddin. Kolam Retensi Amahami direncanakan untuk menampung sementara limpasan yang ada di Kelurahan Dara dengan harapan mengurangi beban limpasan debit banjir yang terjadi. 

In this activity, the dredging of the base and the construction of a parapet with a pair of river stones were carried out aimed at maintaining soil stability and strengthening the embankment or cliffSbesides it will be built or equipped with other supporting facilities in the retention pond in the form of sluices, park areas that function as public spaces, parking areasand so on.

The operational concept of the Amahami Retention Pond is explained as follows:

There are 2 stream inlets, namely from Dara Village and from the east side of the hill of the Amahami Retention Pond

The inlet from Dara Village is channeled through the collecting drain to the Amahami Retention Pond (Pond A)

When the water reaches an elevation of -0.5 to +0.0, the water from Pool A will be drained to Pool B through Box Culvert

.

Pool C will flowto the sea if it is not in high tide condition, if the installation condition of the door at the outlet of pool C will be closed, and the water will be flowed into the sea with the help of a pump.

In the baseflow condition of the pond at an elevation between -0.5 to +0.0

The Pumping System in the retention pond will be carried out by applying Sluice and Pump Automation with SCADA (Supervisory Control and Data Acquisition) For Water System with the following scenario.

.

.

When the Level in Pool B is full or according to the set point, the channel door to Pool C opens.

SCADA will command the PLC and record all activities in this system with real time loger data.

PLC, or Programmable Logic Controller, is a specialized computer used to automate industrial processes. The PLC acts as a "brain" in an automated system, receiving input from sensors and other devices, processing that information based on a pre-programmed set of instructions, and then controlling the output to operate the machine and equipment.

2.1.2. Construction of Taman Ria Retention Pond in Bima City

Administratively, the construction plan for the Taman Ria Retention Pond in Bima City is located in Monggonao Village, Mpunda District, Bima City, West Nusa Tenggara Province.

Administrative boundaries of the Taman Ria Retention Pond Development Plan:

The north is bordered by Santi Village;

The east is bordered by Penato'i Village;

To the south it is bordered by the Manggemaci Village City Park;

To the west it is bordered by Pane Village.

.

In an effort to control flooding in Bima City, the City Government is in the form of increasing the construction of the Taman Ria Retention Pond from the original 4,000 m2 to an area of ±10,401 m2 so that it can enlarge the reservoir of rainwater runoff discharge and not cause overflow.

The activity plan for the Taman Ria Retention Pond is in the form of Pond 1 with an area of 6,658 m² and Pond 2 with an area of 3,743 m² so that it has a total capacity of 17,353 m³. Between Pool 1 and Pool 2 there is no separation channel so the calculation of the pool capacity is calculated as a total capacity.The location of the Taman Ria Retention Pond plan and the flow scheme of the Taman Ria Retention Pond can be seen in the following image.

In this activity, work was carried out on dredging the bottom of the pond, making a soil retaining wall with concrete, garden landscape, and other supporting facilities in the form of sluice gates and pumps. In general, the activities consist of preparatory work, retention pond work, mobile embankment work, pump housework, outlet inlet duct work, outlet inlet sluice gate building work with details can be seen in the table below.

Nature Based Solution (NBS) Concept

In the Taman Ria Retention Pond Landscape, there is a Nature Based Solution (NBS) activity. In this work there is the planting of 20 trees where the type of tree planted is not recommendedas productive trees but trees that benefit from shade for green open spaces such as kersen, ketapang kencana, kiara umbrella, red shoots, and banyans. In addition, it is also considered that plant types are not liked by biota that spread diseases such as mosquitoes, such as lemongrass, lavender, etc.

Technical Design of Taman Ria X Retention Pond

Bima City's flood control in the form of the construction of the Taman Ria Retention Pond with a total area of ±10,401^m2 is an effort to enlarge the reservoir of rainwater runoff discharge so that it does not cause overflow. In addition to temporary shelter, this reservoir can also be used for other facilities including water conservation. This reservoir is expected to be able to accommodate rainwater at peak flood conditions where water cannot be directly flowed to theriver or to the riverand can be flowed downstream by gravity when the outlet conditions towards the river or sea are in a low state.

The operational concept of the Taman Ria Retention Pond is explained as follows:

The Taman Ria Retention Pond has two ponds, where pond 1 and pond 2 are connected or do not have separate channels. The water coming from the Monggo Nao – Pane – Salama Drainage upstream enters the Taman Ria Reservoir through the door of the Taman Olam1and the water flows to the pool 2 .

Water from retention pond 2 will be flowed back to the Monggo Nao – Pane – Salama Primary Channel downstream through the outlet door.

The system in the retention pond will be carried out by applying sluice gate automation with SCADA (Supervisory Control and Data Acquisition) For Water System with the following scenario.

If the elevation of the water level is below an elevation of +5.5 m (WL <5.5 m), then the inlet door and outlet door of the pool will open. The water in the pond will be released;

Ifthe elevation of the water level is between +5.5 m and 7.5 m (5.5 m < WL < 7.5 m), then the inland pool doors are open and the outlet doors of the pool are half open. The water in the pond will be collected andpartially released;

If the elevation of the water level is above +7.5 m ( WL > 7.5 m), then the inlet door and outlet door will be closed. The water in the pond will be accommodated.

The concept of operating the Taman Ria Pond is explained as follows:

Inlet Door

The function of the door at this inlet is to maintain the effect of back water from the channel downstream of the retention pond which has a return flow to the retention pond when the pool capacity has exceeded the normal water level. Because this maximum retention pond has a maximum guard height of 1.5 m from elevation +9 to +10.5. The Peak Elevation Condition in the Monggonao Pane Salama Hulu Drainage is at an elevation of + 8.54.

Looking at the condition at the peak elevation of the drainage upstream of the retention pond and the capacity of this channel is only to reduce flooding when re-Q5mwill need special treatment to overcome the backflow that will occur from the retention pond after the condition of the pond exceeds its normal water level, so it needs door treatment at the retention pond Inlet that is adjusted to the elevation of the door.

Outlet Doors

The concept of door operation downstream of the Taman Ria Retention Pond is as shown in the following table:

The operation of the door downstream of the retention pond can be in the form of a SCADA System just like the Amahami Retention Pond.

Information:

WL : Water Level Condition in the Monggonao Pane Salama Downstream Drainage Retention Pond

Alert 1: The water level condition in the retention pond is still at a safe level for channels upstream and downstream, which is at Elevation + 5.5. The operation of the inlet door and open outlet and retention pool is still able to realease water.

Alert 2: The water level condition in the retention pond is still at a safe level for channels upstream and downstream, namely at an elevation of more than + 5.5 and below +7.5. The operation of the open inlet door of the retention pond holds water, downstream of the pool is still able to realize the discharge and the open outlet door 1/2 is aimed at reducing the load of the retention pond reservoir.

Alert 3. When the water in the channel downstream is full, it reaches an elevation above + 7.5. The retention pond will accommodate the runoff discharge that occurs, the threshold downstream of the pond is closed and the retention pond is in the process of accommodating water flow from elevation + 9 to the top of the water table with a maintenance height still able to accommodate at an elevation of +10. This happened when it experienced a discharge during Q25 re-release and only lasted for 4 hours.

The following is a map of the situation of the Taman Ria Retention Pond along with the elongated and transverse sections of the Taman Ria Retention Pond.

2.3 Suitability of the Location of the Activity Plan with the Spatial Plan

The Bima City Regional Spatial Plan is regulated in Bima City Regional Regulation Number 4 of 20 24 concerning the Bima City Regional Spatial Plan Year 2024 - 2044. To determine the suitability of the location of the activity plan with the spatial plan, it is necessary to analyze the spatial structure plan and the regional spatial pattern plan.

The spatial structure plan is a plan for the arrangement of settlement centers and a network system of infrastructure and facilities that function as a support for the socio-economic activities of the community that hierarchically have functional relationships. The spatial structure plan aims to improve the function and role of service centers as well as improve the quality and service coverage of the urban area's infrastructure network. The following is a description of the suitability of the space structure with the activity plan.

Spatial pattern plan is a spatial allocation distribution plan in an area that includes the allocation of space for protective functions and space allocation for cultivation functions. To find out whether the allocation of the location of the activity plan is in accordance with the activity with the spatial pattern plan map, an overlay of the activity plan location map with a spatial pattern plan is carried out in accordance with the Bima City Regional Regulation Number 4 of 20 2024 concerning the Bima City Regional Spatial Plan Year 2024 – 2044 which is presented in the map on the map on The following image.X

Figure 2.19 Spatial Plan Map of Bima City

Figure 2.20 Analysis of Amahami Retention Pond Space Pattern Plan

Figure 2.21 Analysis of the Taman Ria Retention Pond Space Pattern Plan

Based on the pictures above, it is known that the location of the activity plan is in the RTH designation. In Article 7 paragraph (7) of the Bima City Regional Regulation Number 4 of 20 24 concerning the Bima City Regional Spatial Plan Year 2024 – 2044, it is stated that the strategy for developing mitigation and adaptation in disaster-prone areas as referred to includes the development of green open spaces in areas prone to natural disasters.

In Article 8 paragraph (1) it is stated that the spatial structure plan of the city consists of a service center system, transportation network system, energy network system, telecommunication network system, water resource network system, and urban infrastructure.

Referring to Bima City Regional Regulation Number 4 of 2024 concerning the Bima City Regional Spatial Plan for 2024 – 2044, Article 17 paragraph (2) of water resources infrastructure consists of:

Irrigation network system;

Flood control systems; and

Water resource building.

Paragraph (7) The flood control system as intended in paragraph (2) b in the form of a flood control building includes:

Tanjung retention pond in Tanjung Village, West Rasanae District;

Taman Ria retention pond in Monggonao Village, Mpunda District;

Mande retention pond in South Rabangodu Village, Raba District;

Penanae retention pond in PenanaE Village, Raba District;

Manggemaci retention pond in Sambinae Village, Mpunda District;

Oi Lanco retention pond in Penatoi Village, Mpunda District;

Oi Mbo retention pond in Kodo Village, East Rasanae District;

Jatiwangi retention pond in Jatiwangi Village, Asakota District;

Amahami retention pond in Dara Village, West Rasanae District;

Dodu retention pond in Dodu Village, East Rasanae District;

Nungga retention pond in Nungga Village, East Rasanae District;

Padolo retention reservoir in Kodo Village, East Rasanae District; And

Jetty at the mouth of the Padolo River in Dara Village, West Rasanae District.

Thus, it is concluded that the location of the planned flood control activities of Bima City in the Amahami Retention Pond and the Taman Ria Retention Pond that crosses the RTH designation does not contradict the provisions stipulated in Bima City Regional Regulation Number 4 of 2024 concerning the Bima City Regional Spatial Plan for 2024-2044.

2.4 Indicative Map of Termination of New Permits (PIPPIB)

In completing various efforts to improve and improve the ongoing governance of forests and peatlands, there is a need for continuous efforts to save the existence of primary natural forests and peatlands and to continue efforts to reduce emissions from deforestation and forest degradation, until the availability of forest management preparedness. Therefore, the President of the Republic of Indonesia issued Presidential Instruction of the Republic of Indonesia Number 5 of 2019 concerning the Termination of the Granting of New Permits and the Improvement of Primary Natural Forest andPeat Land Management. The instructions include the termination of the granting of new permits for primary natural forests and peatlands located in conservation forests, protected forests, production forests that include limited production forests, ordinary or permanent production forests, and convertible forests, as well as other areas of other uses as stated in the Indicative Map for the Termination of New Permits.

The Ministry of Environment and Forestry (MoEF) has issued a Decree of the Minister of Environment and Forestry Number: SK.1629/MENLHK- PKTL/IPSDH/PLA.1/3/2022 concerning the Determination of Indicative Maps for the Termination of Business Licensing, Approval of the Use of Forest Areas, or Changes in the Designation of New Forest Areas in Primary Natural Forests and Peatlands in 2022 Period I. The decree also stipulates the map that is an attachment, namely the Indicative Map for the Termination of Business Licensing, Approval of the Use of Forest Areas, or Approval of Changes to the Designation of New Forest Areas in Forests Primary Nature and Peatland (PIPPIB) Year 2022 Period I. In accordance with the map, on the 2007 sheet (Bima), it is known that the location is in an area that has not been terminated with a new permit. The following is presented an overlay of the location map of the activity plan to the Indicative Map for the Termination of New Permits (PIPPIB).

2.5 Alternatives Reviewed

The Amahami Retention Pond Design Review is intended as a continuation of the 2022 Bima City and Regency Flood Reliance DED design against the conditions that occur in 2024. Based on a snapshot of the flood conditions that occurred in Kelurahan Dara taken from the official website of the Bima City Environment Agency (DLH) https://dlh.bimakota.go.id/ on Tuesday, February 13, 2024, it was stated that the flood that occurred on September 10, 2024 occurred due to increased rainfall in Bima City so that inundated the houses of residents in Manggemaci, Paruga and Dara. As a result of this problem, especially what occurs in Dara Village, to reduce the occurrence of floods that occur almost every year in the Dara Village area, one of them is to maximize the condition of the Amahami Retention Pond in Dara Village which has been designed in 2022.

As we already know, the Retention Pond reservoir has a function to accommodate water for a certain time when water cannot be directly flowed to the river body or to the sea, when the river or sea is at high tide or when it is flooded. In addition to temporary shelter, this reservoir can also be used for other facilities including water conservation. This reservoir is expected to be able to accommodate rainwater at peak flood conditions where water cannot be directly flowed to the river or to the sea and can be flowed downstream by gravity when the outlet conditions towards the river or sea are in a low state.

For the Amanami Retention Pond, from a technical aspect, this retention pond is one of the locations chosen because in that location there is an existing pond that can be optimized, besides that there are also several vacant lands around it that can be used to increase the storage capacity of the Amanami retention pond. The Amahami Retention Pond is to help reduce the overflow of water from Dara village and Bima City Bus Terminal which has always been a flood inundation subscription due to its low elevation. With the existence of the Amahami Retention Pond, the drainage system in Dara Village and Dara Terminal will later be partially distributed to the Amahami retention pond. This pond is able to accommodate 39,000 m³ of water with a reduction period of 6 hours. From the economic aspect, the construction of the Amahami retention pond is expected to reduce damage due to flooding inDara Village, wasted time due to floods in Dara Village, so that community productivity is not disturbed and the economy runs smoothly. In addition, with the landscaping arrangement around the amahami retention pond will become one of the spots forpublic activity and is expected to add to the regional PAD.

As for the Taman Ria Retention Pond, when viewed from a technical aspect, the location determined is the ideal location to build a retention pond, where the position is upstream, and has sufficient storage (although not large). With a capacity of around 10,000^m3, it is expected to reduce flooding in the area for approximately 3 hours. Although it is considered short, considering that the location isin the middle of the city and densely populated settlements, it will be very helpful for the community because it can reduce the potential for flooding. Moreover, from the information received from the surrounding community, the height of the flood reached 1.5 meters and damaged many household appliances. From an economic perspective, almost the same as the construction of the Amanami Retention Pond, the construction of the Taman Ria retention pond is also expected to reduce damage caused by floods in Monggonao village, so that community productivity is not disturbed and the economy runs smoothly. In addition, with the landscaping arrangement around the retention pond, Taman Ria will also become one of the spots for community activities and is expected to add to the regional PAD.
