BASE MAP

The Base Map of Barangay Tambis I provides a geographical overview of the community’s administrative divisions and its relationship with the local river system. The barangay is organized into four distinct zones: Purok 1 (shaded in light grey), Purok 2 (blue), Purok 3 (dotted beige), and Purok 4 (green lattice), which are distributed horizontally across the territory. The western boundary of the barangay is defined by the Lawigan River, which separates Tambis I from Barangay Guinsaugon, while its northern and southern borders are shared with Barangay Carnaga and Barangay Tambis 2, respectively. This spatial layout is a fundamental reference for local governance, identifying how the community’s residential and land-use zones are positioned relative to neighboring areas and vital water resources.

 

DRAINAGE MAP

The Drainage Map of Barangay Tambis I illustrates the community’s hydrological network and its relationship to the local infrastructure. The landscape is defined by the Lawigan River, which forms the western boundary of the barangay, and is supported by a series of creeks (light blue lines) and irrigation canals (pink dashed lines) that facilitate water flow across the territory. This water system is mapped alongside the local road network (red and yellow lines), highlighting how drainage is integrated with the community’s transportation routes and shared borders with Barangay Carnaga, Guinsaugon, and Tambis 2. By providing this spatial layout, the map serves as an essential tool for local authorities to monitor water resources and plan for effective flood management and agricultural irrigation.

 

ROAD NETWORK MAP

The Road Network Map of Barangay Tambis I provides a detailed overview of the transportation infrastructure and key geographical features within the community. The network is primarily defined by a grid of barangay roads (solid red lines) concentrated near the western settlement area and the Lawigan River, which serves as a prominent natural boundary. These established roads are supplemented by extensive foot trails (dashed red lines) that extend eastward into the community’s interior and a provincial road that connects the area to the broader region. By mapping these routes alongside irrigation canals and the shared boundaries with Barangay Carnaga, Guinsaugon, and Tambis 2, the map acts as a critical planning tool for managing local mobility and accessing remote agricultural or residential sectors.

 

SETTLEMENT AND INFRA MAP

The Settlement and Infrastructure Map of Barangay Tambis I highlights the concentrated development of the community, primarily located in its western sector. The residential Settlement areas (yellow) are strategically clustered around the intersection of the Provincial Road and the Barangay Road, facilitating ease of access for residents. Key community landmarks are identified within this hub, including Institutional areas (blue) and general Infrastructure sites (red), all of which are situated near the local Irrigation lines and the Lawigan River. By illustrating the proximity of public facilities to the transportation network, this map serves as a vital tool for urban planning and resource allocation within the barangay’s boundaries.

 

EXISTING LAND USE MAP

The Land Use Map of Barangay Tambis I provides a comprehensive spatial analysis of how the community’s territory is utilized for economic and residential purposes. The vast majority of the barangay’s area is dedicated to Permanent Crops, such as coconut and fruit trees, covering approximately 181.32 hectares, primarily in the eastern interior. This is followed by Cash Crops (rice and root crops), which encompass 82.13 hectares and are concentrated near the river and irrigation systems in the west. The Settlement or Built-up area is relatively small, occupying only 3.58 hectares near the main road network, and houses essential facilities like the Elementary School (1.27 ha), High School (1.23 ha), and other institutional buildings such as the Health Center and Barangay Hall. This map serves as a critical guide for local development, illustrating the heavy reliance on agriculture and the concentrated nature of public infrastructure.

 

TENURIAL MAP

The Tenurial Map of Barangay Tambis I provides a legal and administrative overview of land ownership and survey status within the community. The vast majority of the barangay’s territory, totaling approximately 244.394 hectares, is classified under CAD Survey (light green stripes). Other significant tenurial classifications include areas under CLOA (~15.146 ha, dark green), Angkon-Angkon (~15.146 ha, dark blue-green), and a small portion with No Declaration (~3.787 ha, orange). By overlaying these legal statuses with the local road network and the Lawigan River, this map serves as an essential tool for the Local Government Unit to manage land rights, address ownership disputes, and plan for future community development.

 

PROTECTION MAP

The Protection Map of Barangay Tambis I highlights specific zones designated for environmental conservation and resource management to ensure the community’s ecological stability. The map identifies two Highly Elevated Areas Katihagan (2.787 hectares) and Tagbaje (1.862 hectares) alongside designated Proclaimed Protected Areas like Lagnason and Dakit (0.181 hectares). Vital water resources are also prioritized for protection, specifically the Lawigan River and Tagbaje Creek. Furthermore, the map demarcates zones for specific economic activities, including a Quarrying area (14.047 hectares) near the river and a Gold Mining Area (8.571 hectares) in the eastern interior. By identifying these sensitive and high-utility zones, the map serves as a critical spatial guide for balancing environmental preservation with local industry.

 

LAND USE CONFLICT & ISSUE MAP

The Base Map of Barangay Tambis I provides a critical overview of the community’s high-risk zones where agricultural livelihoods and residential safety intersect. The map specifically highlights a extensive cash crop and settlement area located within a flood-prone zone (represented by the light blue checkered pattern), which covers nearly the entire western portion of the barangay. This vulnerable area is bordered by the Lawigan River to the west and is intersected by a network of irrigation canals, creeks, and barangay roads. By visually isolating these areas of concern between the boundaries of Barangay Carnaga, Guinsaugon, and Tambis 2, the map serves as a vital strategic tool for local authorities to prioritize flood mitigation and disaster risk management for both residents and their crops.

 

PROPOSED LAND USE MAP

The Protection Map of Barangay Tambis I serves as a strategic guide for environmental conservation and resource management, identifying specific zones that require protection or specialized oversight. The map highlights Highly Elevated Areas such as Katigahan (2.787 hectares) and Tagbaje (1.862 hectares), along with Proclaimed Protected Areas like Lagnason and Dakit (0.181 hectares). It also prioritizes the protection of vital water resources, specifically the Lawigan River and Tagbaje Creek. Additionally, the map demarcates zones for regulated industrial activities, including a Quarrying area (14.047 hectares) near the riverbank and a Gold Mining Area (8.571 hectares) in the eastern sector. By mapping these environmental and economic assets against the local road network, the document provides a clear spatial framework for sustainable land use and ecological preservation.

 

INTERVENTION MAP

The Protection & Intervention Map of Barangay Tambis I identifies specific environmental strategies to combat land degradation and protect local waterways. The plan designates several inland areas for multi-cropping on erosion potential sites (shaded in dark green) to stabilize the soil in high-elevation zones. Along the Lawigan River, the map mandates the establishment of riparian zones featuring bamboo planting and the installation of gabions to prevent bank collapse. Similar interventions are planned for internal creeks, where tree and bamboo planting are recommended to maintain water quality and bank integrity. By integrating these nature-based solutions with the community’s road and irrigation infrastructure, the map serves as a proactive guide for sustainable land management and disaster risk reduction.
